One, the technical field

The invention mainly applies the fluid mechanics and mechanical principle, relates to the power generation knowledge, and particularly relates to a lever pendulum type power generation system.

Second, background Art

The existing wind or hydroelectric generator is superior to thermal power generation in great popularization due to the adverse factors of stress on an inclined plane, high manufacturing cost, huge engineering amount and the like, but due to the problems in use: such as: the efficiency is low, the ecological environment is changed, the wind power is too small (or too large) and the starting is not possible (or not possible), and the like, and the problems in the application aspect are more.

The ratio of the density of water to the density of air is about 790:1, so the energy of water is much larger than that of wind, the wind and the water are generated when wind energy is utilized, and the utilization of water is far delayed than that of wind energy.

Third, the invention

Aiming at the defects and shortcomings of the prior art, the invention provides the lever pendulum type power generation system which is simple in structure, high in efficiency, wide in application range and capable of changing the collection and conversion mode.

In order to achieve the purpose, the invention adopts the following technical scheme: firstly, a fluid rotary machine driven by fluid (the fluid in the invention refers to the same under wind and water flow) is manufactured, and the fluid rotary machine comprises a shaft hole which is a through hole on the cross line of three or four small straight plates with the same size and which are vertically arranged in an equally-divided and crossed manner. The straight plates are connected through an annular supporting plate, and the supporting plate, the small straight plate and the shaft hole form an impeller. The impeller is shielded on one side by the protective cover by taking the shaft hole as a boundary line, so that the fluid rotating machine is formed, the impeller can be stressed on one side in fluid, and the fluid rotating machine can rotate under the pushing of the fluid.

According to the scheme, the shaft hole pipe of the impeller extends upwards, a large straight plate is installed on the extended shaft hole pipe, and the longitudinal center line of the large straight plate is the center line of the shaft hole. Thus, the axial hole pipe connects the fluid rotary machine and the larger straight plate together, and the fluid rotary machine rotates and the straight plate also rotates.

According to the scheme, a straight rod is inserted into the shaft hole pipe, the top of the straight rod is provided with a straight plate and a fluid rotating machine, a movable fulcrum is arranged at a position which is about 1/4-1/5 away from the lower end of the straight rod, the straight rod forms a lever, and a tension spring is arranged at the bottom end of the lever to form a lever swing system. In the fluid, the fluid rotating machine can rotate under the action of the fluid, the straight plate can rotate along with the fluid, an included angle between the fluid and the straight plate can be repeatedly changed from 0 degree to 90 degrees to 0 degree, the fluid does not apply thrust to the straight plate at 0 degree, the thrust applied to the straight plate by the fluid is maximum when the fluid is rotated to 90 degrees, and the thrust returns to zero when the fluid is rotated to 0 degree, namely the thrust applied to the straight plate is minimum when the straight plate is near 0 degree, and is maximum when the straight plate is near 90 degrees, and the thrust applied to the lever can return to zero from zero to maximum along with the continuous rotation of the straight plate. The effect of extension spring is to make the lever reset, and when the lever received straight board thrust displacement, namely during 0 to 90, the lever received the thrust of straight board and increased gradually and produced the displacement, pulls open the extension spring simultaneously, and after straight board rotated 90, during turning to 0 promptly from 90, the thrust that straight board given the lever reduced gradually, and the pulling force of extension spring is greater than the thrust of straight board gradually, and the extension spring will make the lever reset. It is reasonable that the ideal tension of the tension spring is 1/2 which is the maximum pushing force of the straight plate, so that the pushing force and the pulling force output by the lever swing system are equal. The lever can swing back and forth under the double actions of the straight plate and the tension spring, and the system is a lever swing which is a power source and can output power outwards.

The function of the tension spring in the operation of the system is not all beneficial, and the resistance of the tension spring is firstly overcome in the process that the lever is pushed by the straight plate to generate displacement, so the tension spring plays a resistance function at the moment. In order to reduce the efficiency loss of the part, the resetting problem is solved by adopting a mode that two groups of lever pendulum systems work simultaneously, namely, the straight plates of the two groups of lever pendulums are installed at a difference of 90 degrees without using a tension spring for resetting, when the lever of the lever pendulum (A) is displaced in work, the lever of the lever pendulum (B) is just at the resetting position, the bottoms of the two levers are connected by a rope, and the lever (A) can pull the lever (B) to reset. The two (A and B) are alternately carried out, and the reset of the moving lever can be ensured, so that the system can normally work. There is also a small problem that the pushing force for pushing the lever to move and the pulling force for pulling the lever to reset are changed, one is from small to large, the other is from large to small, in the changing process, the force between the two is always equal at a certain point, so the system seems to be stopped, because the stress condition of the system is continuously changed in the non-stop operation, the condition appears instantly, and then disappears along with the change of the stress condition.

The reciprocating lever pendulum is connected with the rotating disc through a connecting rod and can be converted into rotating motion, and the rotating disc is connected with a generator to generate electricity. The technical requirement is that the swing amplitude of the lever pendulum, namely the moving stroke of the bottom end of the lever pendulum, must be larger than or equal to the rotating diameter of the rotating disc, otherwise the rotating disc cannot complete circular motion, which can be realized by setting the diameter of the rotating disc through determining the swing amount of the lever pendulum in advance, fine adjustment can be performed through the height of the connecting position of the connecting rod and the lever, the part of the stroke larger than the diameter of the rotating disc can be solved by changing a round hole of the connecting rod and the rotating disc into a long hole, and the long hole can absorb and adjust the change of the stroke of the part larger than the diameter of the rotating disc.

Because the diameter of the rotating disc is equal to the swing stroke of the lever pendulum, the numerical control is difficult to control, and sometimes (particularly in the sea wave) the swing amount is determined by the wavelength of the sea wave, namely the swing amount is not a fixed value under some conditions, so that the generator is difficult to realize circular motion, a ratchet planetary machine (which describes the content in another patent reported by the inventor, and the application number: 2020101633543 in the current examination and the repeated description is the same below for convenience of examination) can be adopted to solve the problem, and because the ratchet planetary machine has no fixed value requirement on the swing amount of the lever pendulum, the one-way rotation can be generated as long as the connecting rod reciprocates.

The ratchet wheel planetary machine is a planetary wheel structure which changes the reciprocating motion of a straight plate of a connecting rod into circular motion by utilizing the unidirectional rotation function of a ratchet wheel, and the working structure and the principle of the ratchet wheel planetary machine are as follows: a connecting rod is firstly connected with a double-sided rack of a ratchet planet wheel, two sides of the straight plate double-sided rack are respectively provided with a ratchet wheel, when the rack goes upwards, a left ratchet wheel rotates anticlockwise and drives a gear to rotate, the gear drives an inner gear ring to rotate anticlockwise, and the right ratchet wheel idles due to a one-way transmission function and does not transmit torque to the gear. When the rack moves downwards, the left ratchet idles, the right ratchet rotates anticlockwise and drives the gear to rotate, and the gear drives the inner gear ring to rotate anticlockwise.

The ratchet planetary machine also has a small structural defect, namely the phenomenon that the action transmitted to the gear ring is instant pause at the moment when the rack is converted from ascending to descending or from descending to ascending is shown, and the phenomenon is shown as the pause of the rotation of the inner gear ring, which occurs every week in the rotation process.

Fifth, detailed description of the invention

The technical scheme of the invention is explained by combining the drawings and the examples.

As shown in figure 1, the fluid rotary machine of the invention comprises an impeller, wherein the impeller consists of four rectangular straight plates with the same size, the straight plates are vertically crossed in the longitudinal direction and are equally distributed by taking a central line as a central circumference, shaft holes 1 are formed along the central crossed line of the four straight plates, the straight plates are connected by a support ring 3, the straight plates are divided into 6 blades 2 by the support plate after being crossed, the impeller is shielded at one side by taking the shaft holes 1 as a boundary line by a shield 4, and the fluid rotary machine is formed and can rotate due to the unilateral stress of the impeller in fluid.

As shown in figure 2, the shaft hole 1 of the fluid rotary machine is extended upwards, a large rectangular straight plate 6 is installed on the extended wall pipe, the shaft hole 1 also becomes the shaft hole of the straight plate 6, namely the shaft hole 1 is also the shaft hole of the straight plate 6, and is on the longitudinal central line of the straight plate 6, so that when the fluid rotary machine rotates, the straight plate 6 rotates along with the rotation.

As shown in FIG. 2, the top end of a straight rod is inserted into a shaft hole 1 of a fluid rotary machine, and a movable fulcrum 8 is arranged at a position which is about 1/4-1/5 away from the lower end of the straight rod. The straight rod forms a lever 5, a rope 10 is arranged at the lower end of the lever 5 and connected with another group of lever pendulum systems, and then the lever 7 is connected with a generator 16 through a connecting rod 7, so that a lever pendulum type power generation system is formed.

As shown in fig. 3, the fluid rotating machine rotates in the fluid, the straight plate 6 rotates along with the fluid, when the straight plate 6 rotates to different angles, the pushing force applied to the lever 5 is different, in the rotating process from 0 ° to 90 °, the lever 5 moves along the fluid direction due to the pushing force of the straight plate 6, and since the pushing force changes from zero to the maximum, in the rotating process from 0 ° to 90 ° of the straight plate 6, the pushing force gradually increases, and the tension spring 9 is also gradually pulled apart. Then the straight plate 6 rotates 90 degrees and rotates to 0 degree, the stress of the straight plate 6 is gradually reduced in the rotating process, and the lever 5 is gradually reset under the action of the tension spring 9. In the rotation process of the straight plate 6, the tension spring 9 is pulled open once every 1/4 circles of rotation, the lever 5 is reset once every 1/4 circles of rotation, and the lever 5 swings back and forth under the alternate action of the straight plate 6 and the tension spring 9.

As shown in FIG. 3, the tension spring in the lever pendulum type power generation system works half way in the whole working process to play a role of resistance.

As shown in fig. 4, in order to avoid the resistance action of the tension spring 9, the tension spring 9 is cancelled, and the tension spring resetting mode is replaced by a mode that two groups of lever swing systems work simultaneously, which comprises the following steps: a rope 10 is used at the bottom of the lever 5 to connect the levers 5 of the two systems, and the straight plates 6 of the two systems are arranged at an angle of 90 degrees when the two systems are installed, so that in the work, when the former (A) rotates in the first half circle as shown in figure 4-1, namely when the lever 5 is displaced, the latter (B) rotates in the second half circle as shown in figure 4-2, namely the lever 5 is reset, so that the former pulls the latter to reset, and then the former pulls the latter to reset as in the above condition, or the former (A) and the latter (B) pull each other to reset, although the instant pulling force and the pushing force are equal in the rotating process, the instant pulling force and the resistance of the system are equal, but the continuous operation of the system can be quickly passed through due to inertia.

As shown in fig. 5, the working condition in the sea wave is simpler than that in river water or wind, because the sea wave itself shakes back and forth in the deep sea, the fluid rotary machine and the tension spring do not work at this time, and both can be cancelled, so that the working is simpler. It should be emphasized that, in this case, the uncertainty of the wave length of the sea wave must be considered, and a power generation device with a small rotation radius is adopted as much as possible, because once the swing stroke is smaller than the rotation diameter, the circular motion cannot be completed, and power generation cannot be performed, and other parts similar to the above parts are not described again.

As shown in fig. 6, the structure and vibration damping principle of the ratchet planetary machine: the device consists of a straight plate double-sided rack 11, a ratchet wheel 12, a gear 13, a wave spring 14, a gear ring 15 and a generator 16. Vibration reduction: the gear ring 15 transmits torque to the generator 16 through the wave spring 14, the wave spring 14 is used for absorbing and relieving a pause phenomenon caused by rotation of the gear ring 15 at the moment when the motion direction of the straight plate double-sided rack 11 is changed, namely the moment when the straight plate double-sided rack 11 is changed from ascending to descending or from descending to ascending, the wave spring 14 can also sufficiently transmit the torque to the generator 16, and the generator can normally generate power as usual.

As shown in fig. 7, the structure and the work flow of the ratchet planetary machine are as follows: fig. 7-1 is an enlarged view of the generator, and fig. 7-2 is an enlarged view of the ratchet. As shown in fig. 7-3, when the straight double-sided rack 11 moves upward, the ratchet wheels 12 installed on both sides of the rack 11 rotate, but only the left ratchet wheel 12 transmits a rotational force to the left gear 13 due to the unidirectional rotation function of the ratchet wheels 12, so that the left gear 13 rotates counterclockwise. At this time, the right ratchet 12 idles and does not transmit the rotational force to the right gear 13. After the straight double-sided rack 11 reaches the limit point, it follows that the straight double-sided rack goes downward, as shown in fig. 7-4, the ratchet wheels 12 installed at both sides of the rack 11 rotate, the left ratchet wheel 12 idles due to the function of unidirectional rotation and does not transmit the rotation force to the left gear 13, and at this time, the right ratchet wheel 12 transmits the rotation force to the right gear 13, so that the right gear 13 rotates counterclockwise. The ring gears 15, which are installed outside the two gears 13, are rotated by being alternately pushed by the two gears 13, and both are rotated counterclockwise. This achieves the object that the toothed ring 15 is rotated anticlockwise, whether the rack 11 is up or down, and that it rotates regardless of the stroke.

The structure is a main structure of the invention, and the working principle is as follows:

the fluid rotating machine rotates by itself under the action of fluid, and the straight plate 6 rotates because the fluid rotating machine and the straight plate 6 are coaxial holes.

During the rotation process, the included angle between the straight plate 6 and the fluid can be repeatedly cycled from 0 degrees to 90 degrees and then to 0 degrees, and the stress of the straight plate can be continuously changed from zero to the maximum and then to zero.

Since the top of the lever 5 penetrates into the shaft hole of the straight plate 6, the lever 5 also receives periodic thrust along with the rotation of the straight plate 6, and the thrust can be continuously zero from zero to the maximum and then to zero. The lever 5 generates reciprocating and amplified pushing and pulling force on the connecting rod 7 at the lower end due to the action of the fulcrum 8.

The contained angle of extension spring 9 between straight board 6 and the fluid flow direction is not atress when 0, along with constantly increaseing of lever 5 thrust, extension spring 9 will be pulled open gradually, straight board 6 reachs 90 positions after that, simultaneously lever 5 reachs the limit, straight board 6 can be turned back to 0 again from 90 gradually thereupon, its atress also is constantly reducing, the thrust that lever 5 received also can diminish from the biggest gradually, when being less than extension spring 9's pulling force, extension spring 9 will reset lever 5, continuous circulation like this, the fluid is incessant flows, lever 5 will be continuous produces thrust and pulling force to connecting rod 7, will generate electricity.

In the circulating working process of the system, the tension spring 9 does not work usefully in the process of rotating the straight plate 6 from 0 degree to 90 degrees, namely the pushing process of the connecting rod 7, the tension spring 9 plays a role of resistance in the pulling process by the pushing force to hinder the work, and only after the straight plate 6 rotates 90 degrees, the straight plate rotates from 90 degrees to 0 degree, the tension spring plays a role of resetting, so that the tension force of the tension spring enables the connecting rod 7 to realize the tension force.

The work doing process comprises the following steps: preferably, in the fluid, the fluid rotating machine rotates to drive the straight plate 6 to rotate, the straight plate 6 pushes the lever 5 to shift, then the tension spring 9 resets the lever 5, as a result of shifting and resetting, the lever 5 swings, and the lower end of the lever 5 pushes and pulls the connecting rod 7 and the generator 16 to generate electricity.

The force arm ratio of the lever 5 can be increased and the stress area of the straight plate 6 can be increased according to the requirement to achieve the purpose of obtaining greater efficacy.

The above description is only for the purpose of illustrating the general principles of the present invention, and is intended to cover such departures from the present disclosure as come within known or customary practice within the art to which the invention pertains.
