Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of new energy power generation, in particular to a water electrolysis hydrogen production system based on wind-solar power generation. BACKGROUND

[0002] Under the general trend of global energy pattern towards green and sustainable transformation, water electrolysis hydrogen production, as a highly potential clean energy production technology, has attracted extensive attention and research. Its core principle is to use electric energy to decompose water molecules into hydrogen and oxygen. The produced hydrogen can be used as an efficient and clean energy carrier, applied to fuel cell vehicles, distributed power generation and industrial production, etc., providing a feasible way to reduce dependence on traditional fossil energy and reduce carbon emissions.

[0003] Wind-solar power generation, including solar power generation and wind power generation, has become a key energy source for providing power for water electrolysis hydrogen production process due to its inexhaustible, inexhaustible and environment-friendly advantages. However, the intermittent and fluctuating nature of wind-solar power generation poses a serious challenge to the efficient and stable operation of water electrolysis hydrogen production.

[0004] Taking wind power generation as an example, the natural instability of wind speed makes the output power of wind turbine fluctuate frequently. Even in a relatively stable wind field environment, wind speed will produce continuous small fluctuations due to slight changes in topography, climate conditions and atmospheric turbulence. Such small changes in wind speed will directly lead to changes in output power and current of wind turbine, and in turn make the current delivered to the electrolytic cell fluctuate.

[0005] For water electrolysis hydrogen production, stable current input is one of the key factors to ensure efficient, safe and stable hydrogen production. Unstable current will cause a series of adverse consequences. In terms of hydrogen production efficiency, unstable current will cause frequent changes in electrolysis reaction rate. Since the chemical reaction rate of water electrolysis is directly related to the current intensity, the fluctuation of current will cause the hydrogen generation rate to be unstable, making it difficult for the hydrogen production system to maintain the best production state, thereby reducing the overall hydrogen production efficiency and increasing the production cost of unit hydrogen.

[0013] When the impeller is blown by the wind force, it rotates, thereby driving the rotating shaft to rotate, and driving the main shaft to rotate synchronously under the action of the hydraulic push rod, thereby driving the generator to rotate and converting mechanical energy into electrical energy for water electrolysis.

The transmission gear is fixedly installed on the outer surface of the main shaft away from the horizontal base. The electric push rod is electrically connected to the speed decreasing unit.

[0015] When the speed of the main shaft is lower than the preset value, the controller controls the hydraulic push rod to retract, thereby disconnecting the main shaft and the rotating shaft. At the same time, according to the instantaneous rotating speed of the main shaft driven by the rotating shaft blown by the wind at this time, the gravity ball is swung under the action of the elastic rope, thereby increasing the pressure on the movable plate. As a result, the movable plate contacts the inductive coil on the arc-shaped rod, the effective number of turns of the inductive coil is gradually reduced, the current supplied to the electric push rod is gradually increased, and the controller controls the corresponding electric push rod to extend according to the effective number of turns of the electrically conductive ring iron on the movable plate contacting the inductive coil, thereby driving the first speed increasing gear, the second speed increasing gear or the third speed increasing gear in the corresponding rotating speed interval to mesh with the transmission gear, thereby increasing the rotating speed of the main shaft and ensuring that the current supplied by the generator is quickly and stably within the preset interval, thereby stabilizing small current fluctuations of the wind-solar power generation and improving the hydrogen production efficiency.

[0016] Further, the speed decreasing unit comprises a large gear, an inner tooth ring, an elastic rope, a gravity ball, a support frame, a movable plate, an arc-shaped rod, an inductive coil and a rotating drum.

One end of the elastic rope is fixedly connected to the rotating drum, and the other end is fixedly connected to the gravity ball. One end of the support frame is fixedly connected to the rotating drum, and the other end is rotatably connected to the movable plate. The end of the movable plate close to the rotating drum is rotatably connected to the arc-shaped rod through the electrically conductive ring iron. The arc-shaped rod is fixedly installed on the inner wall of the installation drum. The inductive coil is uniformly wound on the outer surface of the arc-shaped rod. The electrically conductive ring iron on the arc-shaped rod is electrically connected to the electric push rod. The rotating drum is rotatably installed on the boss close to the horizontal base at the end of the annular notch of the installation drum.

[0017] Further, the speed reduction unit further comprises a counterweight, a half-cone block, a pressing plate, a speed reduction block, a magnetic shield, a magnetic block, a spring telescopic cylinder and a ring plate, the counterweight is slidingly installed on the outer surface of the main shaft, the counterweight is placed on the upper surface of the movable plate close to one end of the main shaft, the half-cone block is fixedly installed on the inner surface of the installation cylinder, the pressing plate is abutted with the speed reduction block close to one end surface of the horizontal base, the pressing plate is slidingly installed on the outer surface of the main shaft, the speed reduction block is slidingly connected with the half-cone block, the speed reduction block is made of rubber, the half-cone block is smaller away from one end surface of the horizontal base than close to one end surface of the horizontal base, the speed reduction block is provided with a magnetic block close to one side of the main shaft, the speed reduction block has two, the magnetic blocks of the two speed reduction blocks on the same horizontal plane are opposite in magnetism, the magnetic shield is fixedly installed in the main shaft, the fixed end of the spring telescopic cylinder is fixedly installed on the upper surface of the ring plate, the movable end of the spring telescopic cylinder is fixedly connected with the speed reduction block close to one end of the horizontal base, and the ring plate is fixedly connected with the inner surface of the installation cylinder.

[0018] In the process of driving the main shaft to rotate by the rotating shaft, the large gear is driven to rotate, thereby driving the inner tooth ring meshed with the large gear to rotate, under the transmission of the rotating cylinder, the gravity ball at the end of the elastic rope is rotated, under the action of centrifugal force, the gravity ball deflects outward with a larger deflection amplitude, thereby reducing the pressure on the end of the movable plate, making one end of the movable plate rotate around the support frame, under the action of the gravity of the counterweight, the other end of the movable plate is pressed downward to rotate around the arc-shaped rod, at this time, the counterweight extrudes the pressing plate to drive the speed reduction block to move downward, in the process of moving downward to compress the spring telescopic cylinder, due to the gradually increasing diameter of the half-cone block, the lower parts of the two speed reduction blocks gradually approach each other under the extrusion of the half-cone block, thereby contacting the rotating main shaft, reducing the rotating speed of the main shaft, and the magnetic blocks below the speed reduction block gradually move away from the magnetic shield, at this time, the two magnetic blocks approach each other under the action of opposite magnetic attraction, cooperating with the half-cone block to make the speed reduction block contact the main shaft, reducing the speed of the main shaft, when the rotating speed of the main shaft is higher, the pressure of the gravity ball on the outer end of the movable plate is smaller, the distance of the counterweight descending is more, and the contact area of the speed reduction block and the main shaft is more, thereby the rotating speed of the main shaft is reduced more, the rotating speed of the main shaft is kept in the preset interval, avoiding that the rotating speed of the main shaft is too high to cause the generator to generate a large current fluctuation, thereby the rate of producing hydrogen in the electrolytic tank is unstable, thereby increasing the production cost of producing hydrogen.

[0019] Further, the tooth number ratio of the primary speed increasing gear and the transmission gear is between 2:1 and 5:1, the tooth number ratio of the secondary speed increasing gear is more than that of the primary speed increasing gear, and the tooth number ratio of the tertiary speed increasing gear is more than that of the primary speed increasing gear.

[0020] In order to avoid the sharp change of the rotation speed, when the power is transmitted from the primary speed increasing gear to the transmission gear, the rotation speed is smoothly increased according to the set proportion, and in order to cope with the time-varying wind speed, when the rotation speed of the input power is low, the multi-stage speed increasing system can gradually increase the rotation speed to the required working rotation speed through the cooperation of the gears, and if the input power is unstable, the buffering effect of the multi-stage speed increasing can reduce the influence of the instability on the final output rotation speed, so that the device can maintain good performance under relatively complex working conditions.

[0021] Further, the inductor coil is away from the horizontal base one end for current input end.

[0022] In order to facilitate the gravity ball to swing outward under the action of centrifugal force when the main shaft speed is lower than the preset value, the gravity ball rotates upward along the arc-shaped rod under the action of its own gravity, so as to control the corresponding electric push rod to extend to drive the corresponding speed increasing gear to engage with the transmission gear, thereby increasing the rotation speed of the main shaft, ensuring the output current of the generator stable, and providing good hydrogen production conditions.

[0023] Further, the movable plate is provided with a guide groove at the end away from the main shaft.

[0024] In order to make the gravity ball swing under the action of centrifugal force, the guide groove provides a certain movement path for the gravity ball. Without the guide groove, the swing of the gravity ball is disturbed by vibration, air flow and other interference factors, so that the swing of the gravity ball is more stable and predictable, which is beneficial to the stable operation of the device.

[0025] Further, the hydraulic push rod is electrically connected with the external controller, and the electric telescopic rod is electrically connected with the external controller.

[0026] In order to realize the automation of the device, save labor, and facilitate the controller to identify the rotation of the impeller to drive the rotation of the shaft, so as to drive the rotation speed of the main shaft to reach the preset interval, the controller controls the hydraulic push rod to retract, cooperates with the speed increasing unit to drive the rotation of the main shaft, thereby increasing the rotation speed of the main shaft, so that the output current of the generator reaches the stable interval range, and reduces the problems such as the decrease of hydrogen production efficiency caused by current fluctuation.

[0027] Compared with the prior art, the beneficial effects of the present application are:

[0028] 1. When the rotating speed is too low, the controller controls the hydraulic push rod to retract, disconnecting the main shaft and the rotating shaft, and the gravity ball swings according to the instantaneous rotating speed of the main shaft, increasing the pressure on one end of the movable plate, so that the effective number of turns of the other end of the movable plate and the inductive coil is reduced, the current supplied to the electric push rod is gradually increased, and the controller controls the electric push rod to drive the first speed increasing gear, the second speed increasing gear or the third speed increasing gear corresponding to the rotating speed interval to mesh with the transmission gear, so as to increase the rotating speed of the main shaft, ensure that the current supplied by the generator is quickly and stably in the preset interval, suppress the small current fluctuation of the wind and light power generation, and improve the hydrogen production efficiency.

[0029] 2. When the rotating speed is too high, the gravity ball is deflected outward under the action of centrifugal force, the pressure on one end of the movable plate is reduced, the other end of the movable plate is rotated downward under the action of the gravity of the counterweight, and the speed reducing block is moved downward, the lower part of the speed reducing block is gradually pressed by the half-cone block, and the half-cone block is in contact with the main shaft, the magnetic block in the lower part of the speed reducing block gradually moves away from the anti-magnetic plate, and the half-cone block is in contact with the main shaft, so that the rotating speed of the main shaft is reduced, the pressure of the gravity ball on the outer end of the movable plate is smaller, the distance of the counterweight is greater, the contact area of the speed reducing block and the main shaft is greater, and the rotating speed of the main shaft is reduced to be kept in the preset interval, so that the electrolytic tank is prevented from being unstable in the production of hydrogen gas due to the large current fluctuation of the generator caused by the high rotating speed of the main shaft, and the production cost of hydrogen production is increased.

[0030] 3. The gravity ball swings under the action of centrifugal force, the guide groove on the movable plate provides a certain movement path for the gravity ball, avoids the interference factors such as vibration and air flow, makes the swing of the gravity ball more stable and predictable, and is beneficial to the stable operation of the device.

[0055] In the process that the rotating shaft 22 drives the main shaft 23 to rotate, the large gear 41 is driven to rotate, thereby driving the inner tooth ring 42 meshing with the large gear 41 to rotate, under the transmission of the rotating cylinder 49, the gravity ball 44 at the end of the elastic rope 43 is driven to rotate, under the action of centrifugal force, the gravity ball 44 deflects outward with a large deflection amplitude, thereby reducing the pressure on the end of the movable plate 46, so that one end of the movable plate 46 rotates around the support frame 45, under the action of the gravity of the counterweight 410, the other end of the movable plate 46 is pressed downward to rotate around the arc-shaped rod 47, at this time, the counterweight 410 presses the pressing plate 412 to drive the speed reduction block 413 to move downward, in the process that the speed reduction block 413 moves downward to compress the spring telescopic cylinder 416, since the diameter of the half cone block 411 is getting larger and larger, under the pressing action of the half cone block 411, the lower parts of the two speed reduction blocks 413 gradually approach each other, thereby contacting the rotating main shaft 23, so as to reduce the rotating speed of the main shaft 23, at the same time, the magnetic blocks 415 inside and below the speed reduction block 413 gradually move away from the anti-magnetic plate 414, at this time, the two magnetic blocks 415 approach each other under the action of opposite magnetic attraction, and cooperate with the half cone block 411 to make the speed reduction block 413 contact the main shaft 23, thereby reducing the speed of the main shaft 23, when the rotating speed of the main shaft 23 is higher, the pressure of the gravity ball 44 on the outer end of the movable plate 46 is smaller, the distance of the counterweight 410 descending is more, so that the contact area of the speed reduction block 413 with the main shaft 23 is more, thereby the rotating speed of the main shaft 23 is reduced more, so that the rotating speed of the main shaft 23 is kept in a preset interval, thereby avoiding that the rotating speed of the main shaft 23 is too high to cause the current fluctuation of the generator 24 to be large, so as to cause the rate of producing hydrogen in the electrolytic tank 1 to be unstable, thereby increasing the production cost of producing hydrogen.

[0056] AsFigure 8 As shown, the tooth ratio of the first-stage speed-increasing gear 31 to the transmission gear 35 is between 2:1 and 5:1, the second-stage speed-increasing gear 32 has more teeth than the first-stage speed-increasing gear 31, and the third-stage speed-increasing gear 33 has more teeth than the first-stage speed-increasing gear 31.

[0057] To ensure a moderate speed increase ratio and prevent abrupt changes in speed, the speed increases smoothly according to a set ratio when power is transmitted from the first-stage speed-increasing gear 31 to the transmission gear 35. Simultaneously, to cope with constantly changing wind speeds, the multi-stage speed-increasing system can gradually increase the speed to the required operating speed through the coordinated action of each gear stage when the input power speed is low. If the input power is unstable, the buffering effect of the multi-stage speed increase can reduce the impact of this instability on the final output speed, enabling the device to maintain good performance under relatively complex operating conditions.

[0058] like Figure 6 As shown, the end of the inductor 48 furthest from the horizontal foundation is the current input terminal.

[0059] To facilitate the smaller outward swing amplitude of the gravity ball 44 under the action of centrifugal force when the speed of the main shaft 23 is lower than the preset value, the gravity ball 44 rotates upward along the arc rod 47 with a larger amplitude under its own gravity, thereby controlling the corresponding electric push rod 34 to extend and drive the corresponding speed-increasing gear to mesh with the transmission gear 35, thereby increasing the speed of the main shaft 23, ensuring the stable output current of the generator 24, and providing good hydrogen production conditions.

[0060] like Figure 5 As shown, a guide groove is provided at the end of the movable plate 46 away from the main shaft 23.

[0061] To ensure that the gravity ball 44 swings under centrifugal force, the guide groove provides a defined path for its movement. This prevents the gravity ball 44 from swinging erratically due to vibrations, airflow, and other disturbances, which would occur without the guide groove. The guide groove makes the swing of the gravity ball 44 more stable and predictable, thus contributing to the stable operation of the device.

[0062] like Figure 4 , 9 As shown, the hydraulic push rod 29 is electrically connected to the external controller, and the electric telescopic rod 27 is electrically connected to the external controller.

[0063] In order to automate the device and save manpower, the controller can identify when the impeller 21 rotates and drives the shaft 22 to rotate, thereby driving the main shaft 23 to rotate. If the speed is not within the preset range, the controller controls the hydraulic push rod 29 to retract, which, together with the speed increase unit 3, drives the main shaft 23 to rotate, thereby increasing the speed of the main shaft 23. This ensures that the output current of the generator 24 reaches a stable range, reducing the problems of decreased hydrogen production efficiency caused by current fluctuations.

[0064] The working principle of the present application is as follows:

[0065] When the impeller 21 is blown by the wind force, it rotates to drive the rotating shaft 22 to rotate, and the main shaft 23 is synchronously rotated under the action of the hydraulic push rod 29, thereby driving the generator 24 to rotate and converting mechanical energy into electrical energy. The generator 24 delivers the generated direct current to the positive plate 11 and the negative plate 12, and corresponding chemical reactions occur on the positive plate 11 and the negative plate 12, thereby realizing water electrolysis to obtain hydrogen. At the same time, under the condition of sunlight, the controller delivers current to the electric telescopic rod 27, thereby driving the photovoltaic panel 26 to rotate outward to fully receive sunlight and convert solar energy into electrical energy for the generator 24 in the electrolysis box 1 to store electrical energy.

[0066] When the speed of the main shaft 23 is lower than the preset value, the controller controls the hydraulic push rod 29 to retract, thereby disconnecting the main shaft 23 and the rotating shaft 22. At the same time, according to the instantaneous speed of the rotating shaft 22 driven by the wind speed, the gravity ball 44 is swung under the action of the elastic rope 43, thereby increasing the pressure on the movable plate 46, making the movable plate 46 contact with the inductor coil 48 on the arc-shaped rod 47, gradually increasing the effective number of turns of the inductor coil 48, and gradually increasing the current delivered to the electric push rod 34. According to the effective number of turns of the electrically conductive ring iron on the movable plate 46 contacting with the inductor coil 48, the controller controls the corresponding electric push rod 34 to extend, thereby driving the first-stage speed-increasing gear 31, the second-stage speed-increasing gear 32, or the third-stage speed-increasing gear 33 in the corresponding speed interval to mesh with the transmission gear 35, thereby increasing the speed of the main shaft 23 and ensuring that the current delivered by the generator 24 is rapidly and stably within the preset interval, thereby stabilizing small-amplitude current fluctuations of wind-solar power generation and improving hydrogen production efficiency.

[0067] In the process that the rotating shaft 22 rotates to drive the main shaft 23 to rotate, the large gear 41 is driven to rotate, thereby driving the inner tooth ring 42 engaged with the large gear 41 to rotate, under the transmission of the rotating drum 49, the gravity ball 44 at the end of the elastic rope 43 is driven to rotate, under the action of centrifugal force, the gravity ball 44 deflects outward, thereby reducing the pressure on the end of the movable plate 46, the end of the movable plate 46 rotates around the support frame 45, under the action of the weight of the counterweight 410, the other end of the movable plate 46 is pressed downward to rotate around the arc-shaped rod 47, at this time, the counterweight 410 extrudes the pressing plate 412 to drive the speed reduction block 413 to move downward, in the process that the speed reduction block 413 moves downward to compress the spring telescopic cylinder 416, since the diameter of the half-cone block 411 is larger and larger, under the extrusion of the half-cone block 411, the lower parts of the two speed reduction blocks 413 gradually approach each other, thereby contacting the rotating main shaft 23, the rotating speed of the main shaft 23 is reduced, at the same time, the magnetic blocks 415 in the lower part of the speed reduction block 413 gradually move away from the anti-magnetic plate 414, at this time, the two magnetic blocks 415 approach each other under the action of opposite sex, cooperate with the half-cone block 411 to make the speed reduction block 413 contact the main shaft 23, the speed of the main shaft 23 is reduced, when the rotating speed of the main shaft 23 is higher, the pressure of the gravity ball 44 on the outer end of the movable plate 46 is smaller, the distance of the counterweight 410 descending is more, the contact area of the speed reduction block 413 and the main shaft 23 is more, thereby the rotating speed of the main shaft 23 is reduced more, the rotating speed of the main shaft 23 is kept in the preset interval, the rotating speed of the main shaft 23 is prevented from being too high to cause the current of the generator 24 to fluctuate greatly, thereby the rate of producing hydrogen in the electrolytic tank 1 is prevented from being unstable, thereby the production cost of producing hydrogen is increased.
