Technical Field

The invention relates to an underwater engineering conveyor belt which can dive infinitely deeply and can dive continuously for a very long time.

Background

At present, various diving equipments with different specifications and models are in endless, wherein the most widely used and mature motor power equipment can only be matched with various equipments running in the air, but not matched with various equipments running underwater, and the reason is that:

if the motor is to be operated underwater, a waterproof sealing structure (for example, a sealing ring of various specifications made of a polymer flexible material such as rubber or plastic serving as a main body) must be provided to resist the penetration of the inside of the motor by the outside water body or high-pressure water body (the water body will damage the motor once contacting with the rotating motor rotor), however, the waterproof sealing structure cannot resist the possibility that fluid including water and air passes through the motor in the molecular order:

the bicycle inner tube and the automobile tire can not be used after being not inflated for a period of time, which fully explains that: the flexible inner tube or the tyre made of the high polymer material rubber or plastic as the main body can not resist air as fluid to pass through the flexible inner tube or the tyre with the molecular magnitude, obviously: the gaps between the molecules in the flexible sheet or block made of rubber or plastic as main body are larger than the diameter of the air molecules, except that the speed of the air molecules passing through the gaps between the molecules is slow.

Through phenomena or experiments of daily life, it can also be proved that: liquid molecules as fluid also pass through the waterproof sealing line formed by any flexible sheet made of rubber or plastic as main body, but the passing speed is slow. If bought fried bread stick food is placed in a plastic bag, the phenomenon that oil on the fried bread stick seeps out of the plastic bag can be found quickly, and the phenomenon that the oil leaks out of the plastic bag can be found by naked eyes or hands of people, because the oil serving as liquid belongs to substances which are not easy to volatilize, and leaked oil molecules can keep the state that the leaked oil molecules leak out of the plastic bag continuously in a liquid state easily; however, if water is contained in the plastic bag, water molecules leaking outside the plastic bag immediately disappear in the visual line of the human eye in the form of evaporation.

Obviously: all the waterproof sealing technical measures (mainly born by adopting a solid sealing element) cannot realize effective permanent sealing effect from the molecular level angle; it is easy to imagine that: the underwater matched dragging motor required by any underwater engineering designed by the effect cannot work or rest permanently under water, and the underwater matched dragging motor must be periodically hoisted and pulled to the shore to be disassembled for maintenance (not for maintenance) which takes water seepage as a main task; if the dragging motor with the underwater adaptation of tens of thousands of watts or even megawatts is used, the trouble caused by the maintenance of' periodically disassembling and removing the water seepage (temporarily not counting the influence of the diving depth) in the use process is not imaginable, so that people are afraid of using the dragging motor with the high-power underwater adaptation in permanent underwater engineering or permanent underwater appliances.

Therefore, the method comprises the following steps: at present, a non-underwater dragging motor which can be matched with a diving apparatus and can dive in an unlimited depth for a long time has not been proposed or appeared. This is a big problem that people always want to solve in the underwater appliances (including engineering) which need to be matched with a proper underwater dragging motor.

Disclosure of Invention

The purpose of the invention is as follows:

the technical scheme of the invention is provided only for thoroughly solving the 'big problem' to be solved, namely the 'big problem' of the underwater adapted motor which meets the high requirement.

The key of the invention is that:

the conventional idea of implementing waterproof sealing by using the solid element which is manufactured by taking the rubber or plastic flexible material as the main body and the matched structure in the prior art is bypassed, and other ways are found to realize that the invention can be realized in a genuine way: when the underwater dragging motor is placed under water for continuous work (including idle time periods), the underwater dragging motor can realize ' deep submergence without regular landing for water seepage and maintenance ' (maintenance is not equal to maintenance ') as described in the name of the invention regardless of the submerging depth and the continuous duration time. If such a requirement can be met, no matter how large the power (e.g., millions of kilowatts) produced by the underwater traction motor is and how deep the underwater vehicle can submerge (e.g., kilometers), it is not important, and then it is easy to use the underwater motor in the underwater equipment.

The invention has the characteristics that:

firstly, because the motor of the invention is of a 'fully-sealed' structure, namely, in a metal sealed isolated cavity formed by a metal sealed isolated shield, all seam positions are realized by a non-detachable welding process (as the welding reliability of the prior art is thoroughly solved), and the motor is matched with an underwater appliance in the vertical direction, conditions are created for supporting the external water body to push against the external water body osmotic pressure or the extremely high external water body osmotic pressure (caused by deep diving) in the motor by the incompressible oil liquid lighter than water through the movable matching gap between the motor shaft seal and the rotating shaft from top to bottom in the motor.

If the invention is horizontally placed under water, a gap between the circular rotating shaft and the shaft seal position is also necessarily horizontally placed, the external water pressure at the lower part of the circle is necessarily higher than the external water pressure at the upper part of the circle, external water at the lower part (end side) of the circle shaft seal position can smoothly permeate into the metal sealing isolation cavity of the invention through the shaft seal, and oil in the cavity is extruded out of the invention from the upper part (end side) of the circle shaft seal position, so that the seepage water in the motor is accumulated and then contacts with the motor rotor and leads the rotor to reduce the speed (counter electromotive force caused by the conductive water between the stator and the rotor with high rotating speed), and finally the damage of the motor is caused.

Secondly, because the oil is filled between the stator and the rotor in the invention, although the rotation speed of the underwater vehicle causes some resistance (properly reduces) compared with air, the full exertion of the whole electric energy efficiency of the underwater vehicle cannot be influenced to a great extent as long as the underwater vehicle is matched with the underwater vehicle with not great rotation speed requirement.

It is a well-established prior art that if the high speed torque or the low speed torque required in the practical application can be adjusted by a transmission such as a gearbox.

Third, because the invention has been set up the specialized oil filling nozzle, and, set up in the bottom position of the metal seal isolated cavity, it has not obviously high low part with the shaft seal position of the motor shaft exit that locates at the above-mentioned bottom too, this opens (fills the oil fluid) can close (cut off the oil circuit) oil filling nozzle this can't prevent the fluid molecule from can't cross (only the speed is not fast) specially set up the organization (component) at any time, it is unable to form alone to let the oil fluid in the above-mentioned metal seal isolated cavity leak the gap or channel of the oil molecule from its peripheral or upper position beyond the bottom to go out.

-in the prior art, for example: the waterproof sealing ring made of high molecular rubber and the matched compression structure of the submersible pump form a gap or a passage (only with an unpleasant crossing rate) which cannot prevent fluid (gas or water) molecules from penetrating beyond the gap or the passage at the periphery or the upper part of the integral structure of the submersible pump:

under the compression of external high-pressure water, water molecules of the waterproof sealing element at the bottom of the submersible pump inevitably pass through the waterproof sealing element to enter the submersible pump body, and meanwhile, in the process of extrusion, air molecules at the upper part in the body pass through the waterproof sealing structure at the upper part to leak out to low-pressure water at a higher position outside the submersible pump body. -it is not difficult to see in the process: the continuous infiltration of external water and the accumulation inside the motor are the root cause of two major defects that the submersible pump in the prior art can not dive deeply and must be regularly landed to remove the infiltration maintenance (not maintenance), and: the greater the depth of diving, the shorter the "periodic" cycle time.

Detailed Description

To achieve the object of the present invention, you use the following technique, which is characterized by:

the waterproof sealing measure related to the invention is not formed by a shielding structure formed by a conventional waterproof sealing rubber material element, but is formed by ideally supporting the water seepage pressure of external high-pressure water from inside to outside through the structure of the waterproof sealing rubber material element without the assistance of any waterproof sealing element, and thus the waterproof sealing shielding measures are achieved: the purpose of infinite deep diving and extremely long-time continuous diving is dual;

the depth of the infinite deep diving of the underwater engineering conveyor belt is definitely far greater than that of the prior art;

the underwater engineering conveyor belt can continuously work underwater for a time which is not required to be maintained or repaired and is once more than that of the prior art.

The motor structure adopted by the invention is as follows:

at least the rotor 2 or the rotor 2 and the stator 1 are surrounded by a narrow metal seal isolation shield 4 or a wide metal seal isolation shield 5 in a three-dimensional manner, and a rotating shaft 6 which can vertically penetrate through a motor shaft seal 7 downwards is arranged at the bottom of the narrow metal seal isolation shield 4 or the wide metal seal isolation shield 5;

the bottom of the narrow metal sealing isolation shield 4 or the wide metal sealing isolation shield 5 is provided with an oil filling nozzle D or an oil filling nozzle D which is arranged through a pipe union at the other place of the bottom;

the narrow metal sealing isolation shield 4 or the wide metal sealing isolation shield 5 is filled with oil S;

all splicing gaps related to the narrow metal sealing isolation shield 4 or the wide metal sealing isolation shield 5 are connected through a non-detachable welding process.

The dragging motor structure in the invention is an independent machine type structure which can be separately and additionally matched with other underwater projects:

the structure of the independent machine type is completely the same as the structure of the motor adopted by the invention, except that the matched object is not an underwater engineering conveying belt but other underwater engineering facilities or functional instruments, so that: exactly the same content is not repeated here.

The structure style of another independent machine type structure in the present invention is also substantially the same as the above-mentioned "motor structure adopted in the present invention", except that:

only the bottom of the narrow metal sealing isolation shield 4 or the wide metal sealing isolation shield 5 is provided with an oil filling nozzle D or the bottom is provided with the oil filling nozzle D through a pipe connection at other places; "this piece of content.

The invention relates to a 'full-sealing' type structure problem of a metal sealing isolation shielding cavity, which comprises the following steps:

because the gaps among the metal molecules are smaller than the diameters of the air molecules or the water and oil molecules, the metal sealing isolation shielding cavity forms a fully-sealed structure, and the air or the water and oil molecules can be prevented from passing through the metal sealing isolation shielding cavity; the sealing rings or structures of various specifications made of high molecular materials mainly made of rubber or plastics are absolutely impossible to prevent the fluid molecules from passing through.

Only by eliminating the existence of all the static sealing elements which are usually made of rubber-plastic high polymer materials in the prior art in structural design and only allowing the movable fit gap between the motor-storing rotor 6 and the shaft seal 7 (allowing water or oil to leak from the gap-certainly allowing water or oil molecules to pass through the gap), the 'full-sealing' structural state can be formed.

The invention relates to the problem that the motor rotating shaft 6 must be vertically placed downwards:

according to the known knowledge, any substance has the phenomena of expansion and contraction with heat: when the motor is started to work, the temperature is proper

When the motor is lifted, a little oil in the motor will leak out through a gap between the motor rotating shaft 6 and the shaft seal position 7; when the motor is not in work in power failure, the temperature can be properly reduced, and the external high-pressure water body can seep into the inside along the gap to a little. Such a periodic program will cycle forever without adversely affecting the motor.

If the rotating shaft of the motor is placed upwards, the method cannot be used:

when the motor is not in work and can be properly cooled when the motor is powered off, the external high-pressure water body can slightly seep into the motor along a movable fit gap between the motor rotor 6 and the shaft seal 7, however, the seeped external water body cannot stay or suspend on the top or above the motor but continuously sinks due to the fact that the specific gravity of the water is greater than that of the oil, and the oil in the motor is suspended on the top or above the motor and further is leaked from the gap or extruded to the outside of the motor. Obviously, this is the process that this lets inside fluid of motor be replaced and outwards be hollowed by the external water body of infiltration gradually, just is difficult to take place at last:

the conductive water contacts the motor rotor 2, and then, under the action of the back electromotive force, the motor rotor 2 is decelerated obviously to cause the motor to be damaged under the abnormal condition of overcurrent. -it is clear that:

the above-mentioned bad effect of damaging the motor can be avoided only by the working mode of arranging the rotating shaft 6 of the motor downwards. This should be a well-known common physical phenomenon caused by the electrical problems involved with water being able to conduct electricity, and is described or reminded herein.

In summary, the following steps:

generally, the motor is a mature product, and the motor cannot be easily damaged as long as the motor rotor 2 is ensured to be always in rotating operation in the oil S. Therefore, the motor rotor 2 in the invention is arranged in the metal sealing isolation shielding cavity, so that the problem that the self-damage is easy to occur after the motor rotor is operated for a long time is not worried. Durable instruments driven by motor traction, for example: washing machines, refrigerators and air washers, etc., which generally have reached standards, are equipped with prior art dragging motors as power-generating parts, and the service life of the maintenance-free disposable fittings can be more than 15 years, while the world name brand can reach more than 30 years, and if the best materials are adopted for the preparation, the service life of the maintenance-free disposable fittings can exceed 50 years. Therefore, when the invention which belongs to a simple product adopts a non-detachable welding process to implement a 'full-sealing type' structure (so that the product cannot be detached for maintenance), the service life of the invention for one time is not influenced.
