Technical Field

The invention relates to the field of river energy collection, in particular to a river energy collecting device, a manufacturing method and a collecting method.

Background

The energy of a river is essentially dependent on the river flow and fall, which in turn is generally expressed in terms of flow; the flow rate is typically measured in cubic feet per second (i.e., cubic feet per second through a particular cross-section) or in metric cubic meters per second (meters)³In seconds).

In the aspect of collecting river energy, the river energy is usually collected by using a water turbine, which is a power machine converting the energy of water flow into rotational mechanical energy and belongs to the mainstream machinery in fluid machinery. Most of modern water turbines are installed in hydropower stations and used for driving generators to generate electricity. In a hydropower station, water in an upstream reservoir is guided to a water turbine through a water guide pipe to push a water turbine runner to rotate so as to drive a generator to generate electricity. The water after doing work is discharged to the downstream through the tail water pipeline. The higher the water head and the larger the flow, the larger the output power of the water turbine is. The water turbine and the auxiliary machine are important hydroelectric equipment which are indispensable components in the hydroelectric power industry, are important equipment for realizing energy conservation, emission reduction and environmental pollution reduction by fully utilizing clean renewable energy sources, and the technical development of the equipment is adapted to the development scale of the hydroelectric power industry in China. Under the strong pulling of the power demand in China, the water turbine and auxiliary machine manufacturing industry in China enters the rapid development period, the economic scale and the technical level of the water turbine and auxiliary machine manufacturing industry in China are both obviously improved, and the water turbine manufacturing technology in China reaches the world advanced level. The equipment such as the water turbine is only suitable for large rivers, the low-efficiency and low-cost performance ratio of the rivers with low flow rate, low fall and small flow rate cannot be applied, and the rivers with low flow rate and low fall cannot be efficiently and effectively utilized in the existing rivers all over the world, so that the resource waste is caused.

Besides hydraulic turbines, other current schemes for energy output by using river fall energy include hydraulic ram pumps, waterwheels, Archimedes screw pumps, hydraulic turbine pumps and the like;

particularly, in the technology of converting river energy into differential pressure gas energy, there is a liquid-gas energy technology, that is, a hydraulic air compression technology, which is basically a positive pressure system, that is, a technology of converting mechanical energy of a water fall into a pressure gas higher than atmospheric pressure. The technology of converting the mechanical energy of river fall into negative pressure gas by using the siphon principle also exists, and all the technical schemes of converting river energy into negative pressure gas pressure difference energy by using the siphon phenomenon have at least the following defects:

firstly, the flow is easy to break, and in order to solve the problem, many people adopt thicker pipes which are only supported for a little time but cannot solve the flow breaking problem;

secondly, the siphonage is bound to have negative pressure, the gas in the water can be separated out as long as the negative pressure exists, and the higher the negative pressure is, and the larger the turbulence and the vibration of the water are, the more the gas in the water can be separated out in a violent and large scale manner; if the gas separated out from the water is not discharged, the gas will accumulate at the upper part in the siphon pipe, and the siphon will cut off the flow after the gas accumulates to a certain degree; in order to stop the flow, the water flow rate must be fast, large air mass is broken into small bubbles through high flow rate and is brought into a sewer pipe for suction and discharge, but the efficiency at the moment of high flow rate is low; meanwhile, the high flow rate also means that more gas is separated out in the water at the same time, and finally, the two aspects of difficult siphon flow cutoff and low efficiency are also the results;

thirdly, at the water outlet end of the siphon, gas is separated out due to turbulence or vibration of the water body, and small bubbles are easy to leap upwards;

fourthly, the water inlet flow rate and the water outlet flow rate of the whole siphon are the same, and gas in water is more easily separated out;

fifthly, when gas is sucked into the downward zone of the sewer pipe by high negative pressure, small bubbles are not fused with water much, and the efficiency is not high;

sixthly, the siphon installed in the existing river is easy to enter the garbage to block;

seventhly, the negative pressure of the existing siphon cannot be utilized and is easy to break; the external work cannot be done; even if the device does work outside, the efficiency is extremely low;

eighthly, the flow rate of the effluent cannot be adjusted by the existing siphon; meanwhile, the other disadvantage is that small bubbles mixed in the siphon pipe cannot be effectively discharged downwards along with water;

ninthly, in the aspect of the existing negative pressure utilization, water can be sucked from one place to another place only by using a siphon tube, so that the negative pressure utilization method cannot be applied in practice and cannot utilize the negative pressure efficiently;

the existing siphon has extremely low conversion efficiency and serious energy waste;

eleven, another important problem is that the conversion efficiency is very low and the efficiency is very unstable, and just because the efficiency is very low and unstable, a mature technical scheme for converting river energy into negative pressure gas pressure difference energy by utilizing the siphon phenomenon does not exist at present.

Twelve, especially for low head, low flow river, the prior art using siphon negative pressure has no efficient equipment or method.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure more clear, the embodiments of the present disclosure will be described in detail and fully with reference to the accompanying drawings.

Like reference symbols in the various drawings indicate like elements. It should be noted that the described embodiments are only some of the embodiments of the present disclosure, and not all of the embodiments.

All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the disclosure without any inventive step, are within the scope of protection of the disclosure.

Example 1

As shown in fig. 1 and fig. 4 to 9, the river energy collecting device and the manufacturing method of the invention include: a water storage container 1; the upper water pipe 2 is communicated with the water storage container 1; the sewer pipe 3 is positioned below the water storage container 1 and communicated with the water storage container 1; wherein at least the downcomer 3 is at a vertical angle; the gas pipe 4 is arranged in the water storage container 1, one end of the gas pipe 4 is positioned outside the water storage container 1, and the other end of the gas pipe 4 is positioned above the inside of the water storage container 1; at least one air mixing pipe 5, wherein the air mixing pipe 5 is arranged inside the water storage container 1; one end of the air mixing pipe 5 is positioned above the water storage container 1, and the other end is positioned in the sewer pipe 3. The water feeding pipe 2 can be arranged at a vertical angle or can be arranged at a non-vertical angle, so that the water feeding pipe 2 is communicated with the side surface of the water storage container; the upper water pipe 2, the lower water pipe 3 and the water storage container 1 are communicated to form a siphon structure, negative pressure is arranged in the siphon, so that in use, gas in water can be separated out in the process that water flows through the upper water pipe 2, the important factor for separating out the gas in the water is that the traditional siphon can enable the water flow to generate turbulent flow at the bending part of the siphon, no turbulent flow gas can be separated out in a high negative pressure state, but less gas can be separated out in a large scale, and if turbulent flow and vibration exist, the gas in the water can be separated out in a large scale, so that more and more gas is accumulated on the tops of the upper water pipe 2 and the lower water pipe 3, and finally the siphoning is cut off, and on the other hand, the faster the flow rate of the water flow is, and the more energy is lost (wasted); however, the water storage container 1 is added, so that the turbulence or vibration or excessive water flow disturbance of the water in the upper water pipe 2 can be reduced, and the effect of slowing down the flow velocity of the water is realized, so that the effect of reducing gas precipitation in the water is achieved under the action of various factors, and the problem of siphon flow cutoff is solved;

in addition, the water storage container 1 enables a small amount of gas separated out only in a negative pressure state to stay above the water storage container 1, the inside of the water storage container 1 is already negative pressure, the negative pressure in the sewer pipe 3 and the gas mixing pipe 5 is lower, and the gas mixing pipe 5 arranged in the water storage container 1 sucks the gas in the water storage container 1 into the sewer pipe 3 under the action of higher negative pressure to be discharged to the outside, so that siphonic cutoff is further avoided, and the problem of siphonic cutoff is solved; and the efficiency of discharging gas from the downcomer 3 is significantly improved by the added gas mixing pipe 5;

therefore, the amount of gas separated out from the water is reduced by adding the water storage container 1, and even if a small amount of gas is separated out, the gas is mixed into the sewer pipe 3 through the gas mixing pipe 5 and is taken away; in addition, the added gas conveying pipe 4 enables the gas mixing pipe 5 to suck gas separated out from the upper part inside the water storage container 1, meanwhile, the gas mixing pipe mainly passes through the gas conveying pipe 4 under the action of negative pressure, so that negative pressure equipment is formed, river energy can be converted into negative pressure gas pressure difference energy, and the gas outside the equipment is sucked through the gas conveying pipe 4, namely, the negative pressure is used for doing work outwards. The gas mixing pipe 5 simultaneously carries gas separated out from the water in the water storage container 1 and gas outside downwards through the sewer pipe 3, so that if excessive air separated out from the water is generated, energy for doing work externally is wasted, the arrangement of the water storage container 1 reduces the gas separated out from the water feeding pipe 2, namely the amount of negative pressure for sucking air externally is increased, namely the overall efficiency is increased;

if the air inlet flow of the air conveying pipe 4 is larger than the air mixing flow of the air mixing pipe 5, a large amount of external air can be sucked into the water storage container 1 through the air conveying pipe 4 in a short time, so that siphonic flow cutoff is caused; however, if the air inlet flow of the air delivery pipe 4 is smaller than the air mixing flow of the air mixing pipe 5, the negative pressure energy is wasted; therefore, the air input of the air delivery pipe 4 needs to be controlled in a set range, the air inlet speed of the air delivery pipe is related to the pipe diameter of the air delivery pipe, and the air inlet speed of the air delivery pipe needs to be adapted to the air mixing speed of the air mixing pipe 5, and the standard is as follows: when the invention works, the liquid level of the water in the water storage container 1 is always kept between the end part of the air pipe 4 in the water storage container and the port above the sewer pipe 3, and the siphon is in a state of non-cutoff.

Wherein, in the production implementation, the end parts of the at least one gas mixing pipe 5 are positioned in the downcomer 3 with equal or unequal lengths. As shown in fig. 4 to 9, at least one (i.e., a plurality of) air mixing pipes 5 have unequal lengths, so that the water in the downcomer 3 can more uniformly suck and cut air into small bubbles to bring the small bubbles downward.

As shown in fig. 1, the flow rate in the water storage container 1 is at least not less than the flow rate of the water supply pipe 2 or the water drain pipe 3. Namely, the overflowing cross section of the water storage container 1 is larger than that of the upper water pipe 2 or the lower water pipe 3, so that the water in the upper water pipe 2 flows into the water storage container 1 and then reaches the effect of reducing the flow speed due to the enlarged transition cross section, the turbulence of the water in the upper water pipe 2 can be reduced, the water surface is kept stable, and the precipitation of gas in the water in the upper water pipe 2 is reduced; in addition, the water surface stability also enables the water in the downcomer 3 to reduce turbulence or vibration, so that the water and small bubbles (gas) are more fused in the process of taking the gas away by the downcomer 3, and the situation that the small bubbles are easy to upwards leap after being mutually gathered and enlarged under the condition of turbulence is reduced.

As shown, the diameter of the upper pipe 2 is larger than that of the lower pipe 3. On the basis of the foregoing, it is preferable that the diameter of the upper water pipe 2 is set larger than that of the lower water pipe 3, so that the flow rate of the upper water pipe 2 is reduced and the flow rate of the upper water pipe 2 is reduced under the condition that the flow rate of the lower water pipe 3 is not changed (equal flow rate), which is again beneficial to reducing the precipitation of gas in the water in the upper water pipe 2 during the operation and use. Meanwhile, the embodiment is matched with the water storage container 1 for use, and the combination of the embodiment and the water storage container plays roles of reducing the precipitation of gas in water again and improving the efficiency.

As shown in the figure, in the aspect of the size proportion of the upper water pipe 2 and the lower water pipe 3, in a further experiment based on the former text, the same parameters are used, when the diameter of the lower water pipe 3 is 250mm, the diameter of the upper water pipe 2 is also 250mm, the actually measured conversion efficiency hardly exceeds 25%, the flow speed of water in the upper water pipe 2 is observed to be high, the water surface in the water storage container 1 fluctuates severely, so that the water inlet of the lower water pipe 3 is unstable, the turbulence is large, and the energy loss is large. When the diameter of the water feeding pipe 2 is changed to 500, the water flow in the water storage container 1 is observed to be very stable, and the actually measured conversion efficiency is improved to 52%. This is because when the caliber of the water supply pipe 2 is increased, the flow velocity in the pipe is greatly slowed down, the water flows into the water storage container 1 stably, and the water inflow of the sewer pipe 3 is also stable. Therefore, the diameter of the upper water pipe 2 is at least 1.5 times that of the lower water pipe 3. For example, the diameter of the downcomer 3 is 250mm, and the diameter of the downcomer 2 should preferably be more than 375 mm; where the diameter of the upper pipe 2 is preferably at least 1.5 times the diameter of the lower pipe 3, but may be less than 1.5 times if too high efficiency is not required.

As shown in the foregoing, the pipe diameter of the downcomer 3 is at least 180 mm or more. Wherein the tube diameter is preferably 200 mm.

As shown, at least the end of the gas mixing pipe 5 in the downcomer 3 is at a horizontal angle. Namely, the shape of the gas mixing pipe 5 is approximate to L shape; in other words, the two ends of the air mixing pipe 5, wherein the end inside the downcomer 3 is set (bent) at a horizontal angle; in the experiment, when the air mixing pipe 5 is positioned at a vertical angle, a cavity is formed below the downward flowing water of the downcomer 3, and the end part of the air mixing pipe 5, which is positioned at least in the downcomer 3, is set to be a horizontal angle, and because the downcomer 3 is positioned at a vertical angle, the water in the downcomer 3 flows vertically from top to bottom, so that the air outlet direction of the downcomer and the water flow in the downcomer 3 form an intersecting angle, the gas discharged by the air mixing pipe 5 is directly cut into small bubbles by the water in the downcomer 3, and the smaller the bubbles are, the more the negative pressure is favorable for taking the air downwards; thereby increasing the efficiency, i.e. the external gas sucked away by the underpressure. Meanwhile, the characteristic is matched with the water storage container 1 to be implemented, and is combined with the advantages brought by the water storage container 1, so that the overall efficiency is further improved.

As shown in the figure, the gas mixing pipe 5 in the downcomer 3 is provided with at least one gas outlet slit 11 and/or at least one gas outlet hole. By providing at least one air outlet slit 11 in the main body of the air mixing pipe 5 in the downcomer 3, the air outlet slit 11 can be replaced by an air outlet hole, thereby further improving that the air mixing pipe is more easily cut into small bubbles by the water flowing downwards from the downcomer 3 and flows downwards after being mixed with the water in working use.

As shown, the at least one air outlet slit 11 and/or the at least one air outlet hole are arranged within 180 degrees around the horizontal lower side of the air mixing pipe 5. The lower part of the gas mixing pipe 5 is in a range of 180 degrees, namely a half circle of the lower part of the gas mixing pipe 5 which is positioned in the downcomer 3 and is positioned at a horizontal angle; the at least one air outlet seam 11 and/or the at least one air outlet hole are/is arranged below the horizontal plane, so that water in the downcomer 3 is not easy to enter the air mixing pipe 5 to influence the working efficiency. Wherein in production practice, the gap width of the vent gap 11 is between 1 and 5 mm, preferably 2 mm; and as shown in the figure, when the air outlet slits 11 are arranged, more than two air outlet slits 11 are respectively arranged on each air mixing pipe 5.

As shown in the figure, an inclined plate 12 fixedly connected with the downcomer 3 and/or the gas mixing pipe 5 is arranged above the gas mixing pipe 5 in the downcomer 3. Since various wastes are usually generated in the river, the purpose of the added sloping plate 12 is to prevent or reduce the waste hanging at the position, and the arrangement of the sloping plate 12 also plays a role in guiding the water flow, so that the water in the sewer pipe 3 flows downwards more stably.

As shown in the figure and the foregoing, the liquid level control part 7 communicated with the gas transmission pipe 4 is arranged in the water storage container 1, and when the liquid level control part 7 floats up and down in the water storage container 1, the liquid level control part 7 opens or closes the gas transmission pipe 4. On the basis of the foregoing, when the liquid level control component 7 is not installed, the gas flow ratio between the gas conveying pipe 4 and the gas mixing pipe 5 is preferably that the gas inlet flow of the gas conveying pipe 4 is equal to or less than the gas mixing flow of the gas mixing pipe 5; after the liquid level control component 7 is installed, the gas flow ratio between the gas pipe 4 and the gas mixing pipe 5 can be set to be that the gas inlet flow of the gas pipe 4 is equal to or larger than the gas mixing flow of the gas mixing pipe 5; the liquid level control part 7 is additionally arranged, so that the air inlet flow of the air conveying pipe 4 can be set to be larger than or equal to the air mixing flow of the air mixing pipe 5, the efficiency is increased, when the water level in the water storage container 1 is lowered and siphoning is likely to be about to cut off, the liquid level control part 7 closes or closes the air inlet of the air conveying pipe 4, so that the siphoning is not cut off and is continuously operated, and after the water level in the water storage container 1 is raised, the liquid level control part 7 opens the air conveying pipe 4 and gradually and more opens the air conveying pipe 4; so that the external air is continuously sucked by the negative pressure, thereby achieving the highest efficiency. The embodiment is not limited thereto, if the liquid level control component 7 is replaced by an electromagnetic valve, the position of the electromagnetic valve can be set outside the water storage container 1, and only the liquid level probe can be set inside the water storage container.

As shown in the figure, the liquid level control part 7 is a ball float valve or a solenoid valve. And any other liquid level valve product may also be substituted.

As shown in the figure, the upper end of the downcomer 3 is located inside the water storage container 1 at a level equal to or higher than the bottom of the water storage container 1. By the scheme, the end part above the downcomer 3 is controlled to be at the horizontal position height in the water storage container 1 so as to control different flow rates and flow velocities of the downcomer 3.

As shown in the figure, the position of the upper end part of the downcomer 3 can be adjusted. The height between the upper end part of the downcomer 3 and the liquid level inside the water storage container 1 is lower, the downward flow speed of water inside the downcomer 3 is higher, when the fall is large, the position of the downcomer is moved downwards so as to enable bubbles mixed in water to quickly fall down and prevent the bubbles from floating upwards after being fused, the distance between the water inlet of the downcomer 3 and the liquid level inside the downcomer is adjustable, namely the position of the water inlet at the upper end part of the downcomer 3 is vertically adjustable; the specific embodiment of the adjustment can be that the height of the upper end part of the downcomer 3 can be increased or decreased by adding a pipeline detachably connected with the upper end part of the downcomer 3, or the downcomer 3 can be arranged to be in sliding connection with the water storage container 1, so that the height of the upper end part of the downcomer 3 in the water storage container 1 can be adjusted, or other equivalent schemes can be adopted to realize the height adjustment of the upper end part of the downcomer 3.

As shown in fig. 6 to 8, the horizontal section of the gas mixing pipe 5 in the downcomer 3 accounts for 15% to 65% of the horizontal section of the downcomer 3, so that the mixing efficiency of the gas and the water entering the downcomer 3 from the gas mixing pipe 5 is improved.

Example 1.1

As shown in fig. 9, the shape and structure of the downcomer 3 and the air-mixing pipe 5 are not limited, and the exterior of a plurality of air-mixing pipes may be set in a communicating state in addition to embodiment 1.

As shown in fig. 2 and the foregoing, in the river energy collecting device and the manufacturing method of the invention, in embodiment 2, on the basis of embodiment 1, the water storage container 1, the water feeding pipe 2 and the water discharging pipe 3 therein are replaced by the fluid pipe 6; the fluid pipe 6 comprises an upper water pipe 2 and a lower water pipe 3; wherein at least the downcomer 3 is at a vertical angle; a gas pipe 4 is arranged at the highest horizontal position of the fluid pipe 6, one end of the gas pipe 4 is positioned outside the fluid pipe 6, and the other end of the gas pipe 4 is positioned above the interior of the fluid pipe 6; at least one gas mixing pipe 5, said gas mixing pipe 5 being mounted within said fluid pipe 6; one end of the gas mixing pipe 5 is positioned above the fluid pipe 6, and the other end is positioned in the downcomer 3 inside the fluid pipe 6. On the basis of the embodiment 1, the difference lies in that the water storage container 1 is omitted, so that the original function is also provided under the condition that the characteristics of the water storage container 1 are reduced, only the amount of gas separated out in the process that water flows through the water feeding pipe 2 is increased, and the difference between the amount of the gas separated out and the amount of the gas separated out is not large compared with that of a conventional siphon pipe, so that the condition can be met under the condition that the requirement on the efficiency of the use occasion of the embodiment is not high, and the requirement on cost reduction is met.

Wherein said fluid pipe 6 is preferably arranged in a U-shape or an L-shape or a V-shape or other similar shapes.

As shown in the figure, a liquid level control part 7 is arranged in the fluid pipe 6, the liquid level control part 7 is communicated with the air conveying pipe 4, and when the position of the liquid level control part 7 floats up and down in the fluid pipe 6, the liquid level control part 7 opens or closes the air conveying pipe 4. Through installing liquid level control part 7 in fluid pipe 6 and with the air-supply pipe 4 intercommunication, consequently, when the inside water level of fluid pipe 6 descends, when making the siphon probably be about to cut off the flow, liquid level control part 7 then closes in step or close the admit air of air-supply pipe 4, makes the siphon not appear cutting off the flow to continuous operation for after the water level in fluid pipe 6 rises, liquid level control part 7 then opens in step or increases the flow of air-supply pipe 4, makes and continues to be inhaled outside gas by the negative pressure, thereby realizes the highest of efficiency.

As shown in fig. 3, the highest horizontal position of the fluid pipe 6 is provided with a cavity with a water flow rate not less than that of the upper water pipe 2 and the lower water pipe 3 to replace the water storage container 1. The water flow rate of the water arranged on the main body of the fluid pipe 6 and at the highest horizontal position is not less than the cavities of the upper water pipe 2 and the lower water pipe 3, so that the water storage container in the embodiment 1 is replaced, and under the scheme of the embodiment 2, the adjustment can be conveniently carried out when the efficiency is increased as necessary.

As shown, the upper end of the downcomer 3 is inside the downcomer 2. By this means, as in example 1, the same level of the upper end of the downcomer 3 inside the fluid pipe 6 can be controlled to achieve different flow rates and flow rates for the downcomer 3. And the height of the end above the downcomer 3 inside the fluid pipe 6 is also the same as in embodiment 1, and can be arranged in an adjustable solution.

Example 3

As shown in fig. 1 to 9, the river energy collecting method of the present invention includes the river energy collecting device and the manufacturing method described in embodiments 1 and 2; the specific scheme is as follows: wherein the water supply pipe 2 is disposed upstream of the river;

wherein the downcomer 3 is disposed downstream of a river; discharging water upstream of the river to downstream of the river through the water storage container 1 and the sewer pipe 3 by siphon through the water supply pipe 2; gas precipitated by the upper water pipe 2 and external gas sucked by the gas conveying pipe 4 are positioned in the water storage container 1, so that water forms an internal water level 10; the water storage container 1 is utilized to reduce the turbulence of river water in the upper water pipe 2 so as to reduce the precipitation of gas in water under a high negative pressure state, so that the lower water pipe 3 can stably feed water to improve the efficiency; sucking the gas in the water storage container 1 into the water in the downcomer 3 by the gas mixing pipe 5 through negative pressure and discharging the gas to the downstream of the river; the negative pressure generated in the water storage container 1 is converted into negative pressure gas pressure difference energy, and the negative pressure gas pressure difference energy is used for doing work to the outside through the gas transmission pipe 4. In use, a river of arbitrary flow rate is selected, and the apparatus according to embodiments 1 to 2 of the present invention is disposed at a dam as shown in fig. 1 to 3, in which the upper water pipe 3 is disposed upstream of the river, and the lower end thereof is inserted into the upstream water surface 8; the downcomer 3 is arranged at the downstream of the river, the lower end of the downcomer is inserted into the downstream water surface 9, the upstream water is conveyed to the downstream by using siphoning, and in the process, the river energy is converted into negative pressure gas pressure difference energy by using negative pressure generated by siphoning, and the maximization of energy conversion efficiency is realized; the air outside is sucked through the air delivery pipe 4, namely, the negative pressure does work outwards, so that the water conservancy power generation, the electroless pump water, the electroless aeration oxygenation, the seawater desalination and other purposes are realized outwards.

As shown in the figure, the gas flow rate ratio of the gas transmission pipe 4 and the gas mixing pipe 5 is set to be related to the internal water level 10 in the water storage container 1, so that the internal water level 10 in the water storage container 1 is always kept between the gas transmission pipe 4 and the port of the downcomer 3. Through the scheme, the external work is continuously done through negative pressure.

As shown in the figures, it is preferable to use the structure in which the diameter of the upper water pipe 2 is larger than that of the lower water pipe 3, thereby reducing the flow rate of the upper water pipe 2 to reduce the turbulence or vibration or jumping or tumbling of the water.

As shown in the figure, at least the end of the gas mixing pipe 5 in the downcomer 3 is set to a horizontal angle, so that the end is in direct contact with the water flowing vertically downwards in the downcomer 3, and the gas discharged from the gas mixing pipe 5 is cut into small bubbles by the water in the downcomer 3, thereby improving the gas-liquid mixing efficiency and discharging the gas from the downcomer 3 to the downstream of the river.

As shown in the figure, at least one air outlet slit 11 and/or at least one air outlet hole are/is arranged by the air mixing pipe 5 in the downcomer 3, so that air bubbles mixed in the river water of the downcomer 3 are more uniform.

As shown in the figure, the at least one air outlet slit 11 and/or the at least one air outlet hole are/is arranged in a range of 180 degrees around the horizontal lower part of the air mixing pipe 5 to prevent water from entering the air mixing pipe 5.

As shown in the figure, an inclined plate 12 fixedly connected to the downcomer 3 and/or the air mixing pipe 5 is provided above the air mixing pipe 5 in the downcomer 3 to prevent the accumulation of the garbage of the river.

As shown in the figure, a liquid level control part 7 connected with the gas transmission pipe 4 is arranged in the water storage container 1, so that the liquid level control part 7 floats up and down in the water storage container 1 depending on the internal water level 10 in the water storage container 1, and the liquid level control part 7 opens or closes the gas transmission pipe 4.

As shown in the figure, the position of the upper end part of the downcomer 3 is arranged to be adjustable in height so as to adjust the flow rate of water in the downcomer 3.

As shown in the figure, the horizontal section of the gas mixing pipe 5 in the downcomer 3 is set to occupy 15% -65% of the section of the downcomer 3, so that the river energy collection efficiency is improved.

Wherein the end below the downcomer 3 is located within 1 meter below the downstream water surface 9 to reduce the pressure value at which positive pressure gas is generated and negative pressure is lost.

Wherein the lower end of the upper water pipe 2 is located at least 0.5 m below the upstream water surface 8 to reduce the generation of vortex air intake when water enters.

As mentioned above, the horizontal section of the gas mixing pipe 5 in the downcomer 3 is set to occupy 15% -65% of the section of the downcomer 3, and the specific method is as follows: firstly, acquiring the fall between the upstream water surface 8 and the downstream water surface 9; and by adjusting the distance between the upper end of the downcomer 3 and the internal water level 10; and setting the proportion between the horizontal section of the gas mixing pipe 5 and the section of the downcomer 3 according to the fall and the distance so as to improve the efficiency. In further experiments, different fall heights and heights between the position of the upper end part of the downcomer 3 and the inner water level 10 in the water storage container 1 respectively play important roles in improving the efficiency; in the experiment, the diameter of the downcomer 3 was 250 mm; when the fall between the upstream water surface 8 and the downstream water surface 9 is 0.5-0.7 m, the distance between the position of the upper end part of the downcomer 3 and the inner water surface 10 in the water storage container 1 is 0.15-0.2 m, and the proportion between the horizontal section of the corresponding gas mixing pipe 5 and the section of the downcomer 3 is preferably set to be 15-20%, if the proportion is too high, the efficiency is reduced; when the fall is 1.3-3 m, the distance between the position of the upper end part of the downcomer 3 and the inner water level 10 in the water storage container 1 is preferably 0.15-0.5 m, the proportion of the horizontal section of the gas mixing pipe 5 to the section of the downcomer 3 is preferably set to be 25-65%, and if the proportion is too low, the efficiency is reduced.

On the basis of the above embodiments 1 to 3, in terms of the lengths of the upper water pipe 2 and the lower water pipe 3, the higher the negative pressure of the siphon is, the more easily the gas dissolved in the water is precipitated, the solid negative pressure cannot be too high, and the solid negative pressure needs to be controlled within 8 meters of the pressure of the water column (i.e. the absolute pressure is more than 0.02 mpa).

As shown, the head between the upstream water surface 8 and the downstream water surface 9 should be smaller than the height between the upstream water surface 8 and the internal water surface 10. The height between the upstream water level 8 and the internal water level 10 is called the inverted U clear height; for example, the fall between the upstream water surface 8 and the downstream water surface 9 is 1-2 m, and the net height of the inverted U should be set to 4-7 m, which is to control the equivalent fall. The equivalent fall is a value obtained by subtracting the inverted U net height from the equivalent pure water column height after the average density of the downcomer 3 is reduced after air is introduced;

assuming that the net height of the inverted U is 5 meters and the drop height is 2 meters, the pure water pressure at the water outlet of the downcomer 3 is equal to 7 meters, and after air intake, assuming that the void ratio of the downcomer 3 is 20%, the equivalent pure water height of the downcomer is 7 x (1-20%) =5.6 meters, and the equivalent drop height from the upstream to the downstream is 5.6 meters minus the 5 meters of the net height of the inverted U at this time, which is 0.6 meter. If the difference is 2 meters, the air does not enter a little, which is equal to the difference between pure water of 2 meters at the upstream and the downstream, the water passing amount of a 250mm caliber pipeline per hour can reach 700 square per hour, but if the difference is 0.6 meters, the water passing amount of the 250mm pipeline per hour is 180 square per hour. The pipeline with the same caliber can normally run, and the smaller the overflow is, the lower the flow speed is, the smaller the flow speed is, the lower the flow speed is, the smaller the energy loss of the flow speed is;

however, if the net height of the inverted U is 1 meter, the fall is 2 meters, and the porosity is still 20%, the equivalent fall is (1 + 2) × (1-20%) -1=1.4 meters, the flow rate of the 250 pipeline per hour reaches 500 square, the flow rate is too high, and the efficiency is very low;

the invention has the following parameters: the overflow of the water storage container 1 is at least not less than the overflow of the upper water pipe 2 or the lower water pipe 3, the diameter of the upper water pipe 2 is greater than the diameter of the lower water pipe 3 and the air mixing pipe 5, the position of the upper end part of the lower water pipe 3 is adjustable, the horizontal section of the air mixing pipe 5 in the lower water pipe 3 accounts for 15% -65% of the horizontal section of the lower water pipe 3, and through the adjustment of the above parameters, the energy conversion efficiency of the negative pressure energy acquisition device on the river fall reaches 84.7% to the maximum in the actual tests of engineering and laboratories;

in practical tests of engineering and laboratories, the river energy collecting device, the manufacturing method and the collecting method of the invention calculate the energy conversion efficiency of the river fall as follows:

data to be tested during actual measurement has water flow Q₁(m cultivation/H), head height H₁(m) of the reaction mixture. The power of the water flow is P₁=Q₁/3600*1000*9.8*H₁ ；

Gas flow Q of air inlet under normal pressure₂(m cultivation/H), height of water column under negative pressure H₂(m) of the reaction mixture. Gas at this timePower of P₂=-101325*Q₂/3600*ln(1-1000*9.8*H₂/101325).

Energy conversion efficiency η = P at this time₂/P₁ 。
