Description

Technical Field

[0001] The present invention relates to the technical field of renewable energy power generation, and in particular to a water electrolysis hydrogen production system based on wind and solar power generation. Background Art

[0002] As the global energy landscape is shifting towards green and sustainable development, water electrolysis to produce hydrogen has attracted extensive attention and research as a clean energy production technology with great potential. Its core principle is to use electricity to decompose water molecules into hydrogen and oxygen. The generated hydrogen can be used as an efficient and clean energy carrier in many important fields such as fuel cell vehicles, distributed power generation and industrial production, providing a feasible way to reduce dependence on traditional fossil energy and reduce carbon emissions.

[0003] Wind and solar power generation, including solar power generation and wind power generation, has become a key energy source for providing electricity for the electrolysis of water to produce hydrogen due to its inexhaustible and environmentally friendly advantages. However, the inherent intermittent and volatile problems of wind and solar power generation have brought severe challenges to the efficient and stable operation of electrolysis of water to produce hydrogen.

[0004] Taking wind power generation as an example, the natural instability of wind speed causes the power output of wind turbines to fluctuate frequently. Even in a relatively stable wind farm environment, wind speed will continue to fluctuate slightly due to subtle changes in terrain and climate conditions, as well as atmospheric turbulence. Such slight changes in wind speed will directly lead to corresponding changes in the output power and current of the wind turbine, which in turn causes the current delivered to the electrolyzer to fluctuate.

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

[0006] The purpose of the present invention is to provide a water electrolysis hydrogen production system based on wind and solar power generation to solve the problems raised in the prior art.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] The electrolysis water hydrogen production system based on wind and solar power generation comprises an electrolytic box, a power generation unit, a speed increasing unit and a speed reducing unit. The electrolytic box is placed on a horizontal basis, the power generation unit is fixedly installed on one end of the electrolytic box away from the horizontal basis, the power generation unit is fixedly connected to the speed increasing unit, the speed increasing unit is fixedly connected to the power generation unit, the speed increasing unit has the function of increasing the speed of the power generation unit, the speed reducing unit is fixedly connected to the power generation unit, the speed reducing unit is electrically connected to the speed increasing unit, and the speed reducing unit has the function of reducing the speed of the power generation unit.

[0009] The electrolyzer is used for the electrolysis of water to obtain hydrogen and oxygen. The power generation unit is used to convert wind power and light energy into electrical energy. The speed increasing unit is used to increase the speed when the wind speed decreases during wind power generation, causing the output shaft speed to decrease, making the current output unstable and causing the hydrogen production effect to deteriorate. The speed reduction unit is used to adjust the speed to ensure the stability of the output current when the wind speed is too high and the output shaft speed is too fast, causing the output current to fluctuate. In order to ensure the stability of power generation during the hydrogen production process during wind and solar power generation, when the wind force suddenly changes, the small current fluctuations are smoothed out by adjusting the speed increasing unit and the speed reduction unit to stabilize the current entering the power generation unit.

[0010] Furthermore, a positive plate and a negative plate are provided inside the electrolytic box, the positive plate is fixedly installed inside the electrolytic box, the negative plate is fixedly installed inside the electrolytic box, the positive plate is electrically connected to the power generation unit, and the negative plate is electrically connected to the power generation unit.

[0011] The generator transmits the generated direct current to the positive plate and the negative plate, where corresponding chemical reactions occur, thereby realizing the electrolysis of water to produce hydrogen.

[0012] Furthermore, the power generation unit includes an impeller, a rotating shaft, a main shaft, a generator, a mounting cylinder, a photovoltaic panel, an electric telescopic rod, a connecting plate and a hydraulic push rod, wherein the impeller is fixedly connected to one end of the rotating shaft away from the horizontal foundation, the other end of the rotating shaft is fixedly connected to the connecting plate, the end of the main shaft away from the horizontal foundation is fixedly connected to the fixed end of the hydraulic push rod, the main shaft is fixedly connected to the speed reduction unit, the output end of the hydraulic push rod is slidably connected to the connecting plate, the rotating shaft is installed inside the mounting cylinder, the other end of the main shaft is fixedly connected to the output shaft of the generator, the main shaft is installed inside the mounting cylinder, the generator is fixedly installed inside the electrolytic box, the generator is electrically connected to the positive plate, the generator is electrically connected to the negative plate, the mounting cylinder is fixedly installed on the surface of one end of the electrolytic box away from the horizontal foundation, the photovoltaic panel is rotatably installed on the outer surface of the mounting cylinder, the fixed end of the electric telescopic rod is fixedly installed on the outer surface of the mounting cylinder, the telescopic end of the electric telescopic rod is fixedly connected to the photovoltaic panel, the connecting plate is fixedly connected to the speed increase unit, and an annular notch is provided on the mounting cylinder for installing and fixing the speed reduction unit.

[0013] When the impeller is blown by wind, it rotates, thereby driving the rotating shaft to rotate. Under the action of the hydraulic push rod, the main shaft is driven to rotate synchronously, thereby driving the generator to rotate and convert mechanical energy into electrical energy for water electrolysis. At the same time, in the presence of sunlight, the controller transmits current to the electric telescopic rod, so that the photovoltaic panel rotates outward, fully receiving sunlight, converting solar energy into electrical energy to store electrical energy for the generator in the electrolysis box.

[0014] Furthermore, the speed increasing unit includes a first-stage speed increasing gear, a second-stage speed increasing gear, a third-stage speed increasing gear, an electric push rod and a transmission gear. The first-stage speed increasing gear is fixedly connected to the connecting plate through the electric push rod, the second-stage speed increasing gear is fixedly connected to the connecting plate through the electric push rod, the third-stage speed increasing gear is fixedly connected to the connecting plate through the electric push rod, the transmission gear is fixedly installed on the outer surface of one end of the main shaft away from the horizontal base, and the electric push rod is electrically connected to the speed reduction unit.

[0015] When the speed of the main shaft is lower than the preset value, the controller controls the hydraulic push rod to retract, releases the connection between the main shaft and the rotating shaft, and at the same time, according to the wind speed at this time, the rotating shaft is blown to drive the instantaneous speed of the main shaft to rotate, and the gravity ball is driven to swing under the action of the elastic rope, thereby increasing the pressure on the movable plate, so that the movable plate contacts the inductor coil on the arc rod, the effective number of turns of the inductor coil gradually decreases, and the current delivered to the electric push rod gradually increases. According to the effective number of turns of the conductive ring iron on the movable plate in contact with the inductor coil at this time, the controller controls the corresponding electric push rod to extend respectively, driving the first-stage speed increase gear, the second-stage speed increase gear or the third-stage speed increase gear in the corresponding speed range to engage with the transmission gear, thereby increasing the speed of the main shaft, ensuring that the transmission current of the generator is quickly stabilized within the preset range, smoothing out the small current fluctuations of wind and solar power generation, and improving the hydrogen production efficiency.

[0016] Furthermore, the speed reduction unit includes a large gear, an inner gear ring, an elastic rope, a gravity ball, a support frame, a movable plate, an arc rod, an inductor coil and a rotating drum. The large gear is fixedly mounted on the outer surface of the main shaft, the inner gear ring is meshed with the large gear, the outer surface of the inner gear ring is fixedly connected to the 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, one end of the movable plate close to the rotating drum is rotatably connected to the arc rod through a conductive ring iron, the arc rod is fixedly mounted on the inner wall of the mounting cylinder, the inductor coil is evenly wound on the outer surface of the arc rod, the conductive ring iron provided on the arc rod is electrically connected to the electric push rod, and the rotating drum is rotatably mounted on a boss near one end of the horizontal base of the annular notch opened in the mounting cylinder.

[0017] Furthermore, the speed reduction unit also includes a counterweight block, a semi-conical block, a pressure plate, a speed reduction block, an anti-magnetic plate, a magnetic block, a spring telescopic cylinder and a ring plate, the counterweight block is slidably mounted on the outer surface of the main shaft, the counterweight block is placed on the upper surface of the movable plate close to one end of the main shaft, the semi-conical block is fixedly mounted on the inner surface of the mounting cylinder, the pressure plate is close to an end surface of the horizontal base and abuts against the speed reduction block, the pressure plate is slidably mounted on the outer surface of the main shaft, the speed reduction block and the semi-conical block are slidably connected, the speed reduction block is made of rubber material, the end surface of the semi-conical block away from the horizontal base is smaller than the end surface close to the horizontal base, a magnetic block is arranged on the side of the speed reduction block close to the main shaft, there are two speed reduction blocks, and the magnetic properties of the two magnetic blocks on the same horizontal plane of the speed reduction blocks are opposite, the anti-magnetic plate is fixedly mounted inside the main shaft, the fixed end of the spring telescopic cylinder is fixedly mounted on the upper surface of the ring plate, the movable end of the spring telescopic cylinder is fixedly connected to one end of the speed reduction block close to the horizontal base, and the ring plate is fixedly connected to the inner surface of the mounting cylinder.

[0018] In the process of the rotating shaft driving the main shaft to rotate, the large gear is driven to rotate, thereby driving the inner gear ring meshing with it to rotate. Under the transmission action of the rotating drum, the gravity ball at the end of the elastic rope is driven to rotate. Under the action of centrifugal force, the gravity ball deflects outward with a larger amplitude, thereby reducing the pressure on the end of the movable plate, so that one end of the movable plate rotates around the support frame. Under the action of the weight block's own gravity, the other end of the movable plate is pressed downward to rotate around the arc rod. At this time, the weight block squeezes the pressure plate to drive the speed reduction block to move downward. In the process of the speed reduction block moving downward to compress the spring telescopic cylinder, due to the increasing diameter of the semi-conical block, the lower parts of the two speed reduction blocks gradually come into contact with each other under the action of the semi-conical block squeezing. The two magnetic blocks are attracted to each other and cooperate with the semi-conical block to make the speed reduction block contact with the main shaft, thereby reducing the speed of the main shaft. When the speed of the main shaft is higher, the pressure applied by the gravity ball to the outer end of the movable plate is smaller, the distance the counterweight block drops is greater, and the contact area between the speed reduction block and the main shaft is greater, thereby correspondingly reducing the speed of the main shaft more, so that the speed of the main shaft is maintained within the preset range, avoiding the high speed of the main shaft causing large current fluctuations in the generator, resulting in unstable rate of hydrogen production in the electrolytic box, thereby increasing the production cost of hydrogen production.

[0019] Furthermore, the tooth number ratio between the first-stage speed-increasing gear and the transmission gear is between 2:1 and 5:1, the number of teeth of the second-stage speed-increasing gear is greater than that of the first-stage speed-increasing gear, and the number of teeth of the third-stage speed-increasing gear is greater than that of the first-stage speed-increasing gear.

[0020] In order to achieve a moderate speed increase ratio and avoid drastic changes in speed, when the power is transmitted from the first-stage speed increase gear to the transmission gear, the speed increases steadily according to the set ratio. At the same time, in order to cope with the ever-changing wind speed, when the speed of the input power is low, the multi-stage speed increase system can gradually increase the speed to the required working speed through the synergy of gears at each stage. 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, so that the device can maintain better performance under relatively complex working conditions.

[0021] Furthermore, the end of the inductor coil away from the horizontal base is a current input end.

[0022] In order to facilitate that when the main shaft speed is lower than the preset value, the gravity ball swings outward with a smaller amplitude under the action of centrifugal force, and rotates upward along the arc rod with a larger amplitude under the action of its own gravity, thereby controlling the corresponding electric push rod to extend and drive the corresponding speed-increasing gear to engage with the transmission gear, thereby increasing the main shaft speed, ensuring the stability of the generator output current, and providing good hydrogen production conditions.

[0023] Furthermore, a guide groove is provided at an end of the movable plate 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. When there is no guide groove, the swing of the gravity ball is prevented from becoming chaotic due to interference factors such as vibration and air flow, making the swing of the gravity ball more stable and predictable, which is conducive to the stable operation of the device.

[0025] Furthermore, the hydraulic push rod is electrically connected to an external controller, and the electric telescopic rod is electrically connected to an external controller.

[0026] In order to realize the automation of the device and save manpower, it is convenient for the controller to identify that the rotation of the impeller drives the rotation of the shaft, so that the speed of the main shaft does not reach the preset range. The controller controls the hydraulic push rod to contract and cooperates with the speed increase unit to drive the main shaft to rotate, thereby increasing the main shaft speed and making the output current of the generator reach a stable range, reducing the occurrence of problems such as decreased hydrogen production efficiency caused by current fluctuations.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. When the speed is too low, the present invention controls the hydraulic push rod to retract through the controller to release the connection between the main shaft and the rotating shaft. At the same time, the gravity ball is swung according to the instantaneous speed of the main shaft, thereby increasing the pressure on one end of the movable plate, thereby reducing the effective number of turns between the other end of the movable plate and the inductor coil, and gradually increasing the current delivered to the electric push rod. The controller drives the first-stage speed-increasing gear, the second-stage speed-increasing gear or the third-stage speed-increasing gear in the corresponding speed range to mesh with the transmission gear according to the effective number of turns of contact between the conductive ring iron on the movable plate and the inductor coil at this time, thereby increasing the speed of the main shaft, ensuring that the transmission current of the generator is quickly stabilized within the preset range, smoothing out the small current fluctuations of wind and solar power generation, and improving the hydrogen production efficiency.

[0029] 2. When the rotation speed is too high, the gravity ball of the present invention deflects outward with a larger amplitude under the action of centrifugal force, thereby reducing the pressure on one end of the movable plate, so that the other end of the movable plate rotates downward under the action of the gravity of the counterweight block, pushing the speed reduction block to move downward. In the process of the speed reduction block moving downward, the semi-conical block squeezes the lower part of the speed reduction block and gradually approaches each other to contact the main shaft, thereby reducing the rotation speed of the main shaft. At the same time, the magnetic block at the bottom of the speed reduction block gradually moves away from the anti-magnetic plate and approaches each other to cooperate with the semi-conical block to make the speed reduction block contact with the main shaft, thereby reducing the speed of the main shaft. The higher the rotation speed of the main shaft, the smaller the pressure applied by the gravity ball to the outer end of the movable plate, the longer the distance the counterweight block descends, the larger the contact area between the speed reduction block and the main shaft, and the rotation speed of the main shaft is reduced to be maintained within the preset range, thereby avoiding excessively high spindle speed causing large current fluctuations in the generator, resulting in unstable rate of hydrogen production in the electrolytic box, thereby increasing the production cost of hydrogen production.

[0030] 3. The present invention provides a guide groove on the movable plate to make the gravity ball swing under the action of centrifugal force. The guide groove provides a certain movement path for the gravity ball, avoiding the gravity ball from becoming disorderly due to interference factors such as vibration and air flow, making the swing of the gravity ball more stable and predictable, which is conducive to the stable operation of the device.

The arc rod 47 is fixedly installed on the inner wall of the mounting cylinder 25. The inductor 48 is evenly wound on the outer surface of the arc rod 47. The conductive ring iron set on the arc rod 47 is electrically connected to the electric push rod 34. The rotating drum 49 is rotatably installed on a boss at one end of the annular groove opened in the mounting cylinder 25 near the horizontal foundation.

[0054] like Figure 6 , 10As shown in Figures 11, the speed reduction unit 4 also includes a counterweight block 410, a semi-conical block 411, a pressure plate 412, a speed reduction block 413, a magnetic shielding plate 414, a magnetic block 415, a spring telescopic cylinder 416 and a ring plate 417. The counterweight block 410 is slidably mounted on the outer surface of the main shaft 23, the counterweight block 410 is placed on the upper surface of the movable plate 46 close to one end of the main shaft 23, the semi-conical block 411 is fixedly mounted on the inner surface of the mounting cylinder 25, the pressure plate 412 is close to one end of the horizontal base and abuts against the speed reduction block 413, the pressure plate 412 is slidably mounted on the outer surface of the main shaft 23, and the speed reduction block 413 is slidably connected to the semi-conical block 411 The speed reduction block 413 is made of rubber, the end face of the semi-conical block 411 away from the horizontal foundation is smaller than the end face close to the horizontal foundation, a magnetic block 415 is arranged on the side of the speed reduction block 413 close to the main shaft 23, there are two speed reduction blocks 413, and the magnetic properties of the magnetic blocks 415 of the two speed reduction blocks 413 on the same horizontal plane are opposite, the anti-magnetic plate 414 is fixedly installed inside the main shaft 23, the fixed end of the spring telescopic cylinder 416 is fixedly installed on the upper surface of the ring plate 417, the movable end of the spring telescopic cylinder 416 is fixedly connected to the end of the speed reduction block 413 close to the horizontal foundation, and the ring plate 417 is fixedly connected to the inner surface of the mounting cylinder 25.

[0055] In the process of the rotating shaft 22 driving the main shaft 23 to rotate, the large gear 41 is driven to rotate, thereby driving the inner gear ring 42 meshing therewith to rotate. Under the transmission action 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 the weight block 410's own gravity, the other end of the movable plate 46 is pressed downward to rotate around the arc rod 47. At this time, the weight block 410 squeezes the pressure plate 412 to drive the speed reduction block 413 to move downward. In the process of the speed reduction block 413 moving downward to compress the spring telescopic cylinder 416, due to the increasing diameter of the semi-conical block 411, the lower parts of the two speed reduction blocks 413 are gradually squeezed by the semi-conical block 411. The two magnetic blocks 415 are close to each other, thereby contacting the rotating main shaft 23 and reducing the rotation speed of the main shaft 23. At the same time, the magnetic block 415 at the bottom of the speed reduction block 413 gradually moves away from the anti-magnetic plate 414. At this time, the two magnetic blocks 415 are close to each other under the action of opposite attraction and cooperate with the semi-conical block 411 to make the speed reduction block 413 contact with the main shaft 23, thereby reducing the speed of the main shaft 23. When the speed of the main shaft 23 is higher, the pressure applied by the gravity ball 44 to the outer end of the movable plate 46 is smaller, and the distance the counterweight block 410 drops is longer, so that the contact area between the speed reduction block 413 and the main shaft 23 is larger, thereby correspondingly reducing the speed of the main shaft 23 more, so that the speed of the main shaft 23 is maintained within the preset range, avoiding the excessively high speed of the main shaft 23 causing the generator 24 to generate large current fluctuations, resulting in an unstable rate of hydrogen production in the electrolytic box 1, thereby increasing the production cost of hydrogen production.

[0056] like Figure 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 number of teeth of the second-stage speed-increasing gear 32 is greater than that of the first-stage speed-increasing gear 31 , and the number of teeth of the third-stage speed-increasing gear 33 is greater than that of the first-stage speed-increasing gear 31 .

[0057] In order to make the speed increase ratio appropriate and avoid the rapid change of the speed, when the power is transmitted from the first-stage speed increase gear 31 to the transmission gear 35, the speed is steadily increased according to the set ratio. At the same time, in order to cope with the ever-changing wind speed, when the speed of the input power is low, the multi-stage speed increase system can gradually increase the speed to the required working speed through the synergy of the gears at each level. 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, so that the device can maintain good performance under relatively complex working conditions.

[0058] like Figure 6 As shown, one end of the inductor 48 away from the horizontal base is a current input end.

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

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

[0061] In order to make the gravity ball 44 swing under the action of centrifugal force, the guide groove provides a certain movement path for the gravity ball 44. In order to avoid the swing of the gravity ball 44 becoming chaotic due to interference factors such as vibration and air flow when there is no guide groove, the swing of the gravity ball 44 is made more stable and predictable, which is conducive 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 realize the automation of the device and save manpower, the controller can identify that the rotation of the impeller 21 drives the rotating shaft 22 to rotate, thereby driving the main shaft 23 to rotate. When the speed does not reach the preset range, the controller controls the hydraulic push rod 29 to contract and cooperate with the speed increase unit 3 to drive the main shaft 23 to rotate, thereby increasing the speed of the main shaft 23, so that the output current of the generator 24 reaches a stable range, and reduces the occurrence of problems such as decreased hydrogen production efficiency caused by current fluctuations.

[0064] Working principle of the present invention:

[0065] When the impeller 21 receives the wind force, it rotates, thereby driving the rotating shaft 22 to rotate, and under the action of the hydraulic push rod 29, the main shaft 23 is driven to rotate synchronously, thereby driving the generator 24 to rotate and convert mechanical energy into electrical energy. The generator 24 transmits 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 produce hydrogen. At the same time, in the presence of sunlight, the controller transmits current to the electric telescopic rod 27, so that the photovoltaic panel 26 rotates outward, fully receives sunlight, and converts solar energy into electrical energy to store electrical energy for the generator 24 in the electrolytic box 1.

[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, release the connection between the main shaft 23 and the rotating shaft 22, and at the same time, according to the wind speed at this time, the rotating shaft 22 is blown to drive the instantaneous speed of the main shaft 23 to rotate, and under the action of the elastic rope 43, the gravity ball 44 is driven to swing, increasing the pressure on the movable plate 46, so that the movable plate 46 is in contact with the inductor 48 on the arc rod 47, the effective number of turns of the inductor 48 gradually increases, and the current delivered to the electric push rod 34 gradually increases. According to the effective number of turns of the conductive ring iron on the movable plate 46 in contact with the inductor 48 at this time, the controller controls the corresponding electric push rod 34 to extend, driving the first-stage speed increase gear 31, the second-stage speed increase gear 32 or the third-stage speed increase gear 33 in the corresponding speed range to engage with the transmission gear 35, thereby increasing the speed of the main shaft 23, ensuring that the transmission current of the generator 24 is quickly stabilized within the preset range, smoothing out the small current fluctuations of wind and solar power generation, and improving the hydrogen production efficiency.

[0067] In the process of the rotating shaft 22 driving the main shaft 23 to rotate, the large gear 41 is driven to rotate, thereby driving the inner gear ring 42 meshing therewith to rotate. Under the transmission action 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, so that one end of the movable plate 46 rotates around the support frame 45, and under the action of the weight block 410's own gravity, the other end of the movable plate 46 is pressed downward to rotate around the arc rod 47. At this time, the weight block 410 squeezes the pressure plate 412 to drive the speed reduction block 413 to move downward. In the process of the speed reduction block 413 moving downward to compress the spring telescopic cylinder 416, due to the increasing diameter of the semi-conical block 411, the lower parts of the two speed reduction blocks 413 gradually come into contact with each other under the action of the squeezing of the semi-conical block 411. The two magnetic blocks 415 are attracted to each other by opposite charges and cooperate with the semi-conical block 411 to make the speed reduction block 413 contact with the main shaft 23, thereby reducing the speed of the main shaft 23. When the speed of the main shaft 23 is higher, the pressure applied by the gravity ball 44 to the outer end of the movable plate 46 is smaller, and the distance the counterweight block 410 drops is longer, so that the contact area between the speed reduction block 413 and the main shaft 23 is larger, thereby correspondingly reducing the speed of the main shaft 23 more, so that the speed of the main shaft 23 is maintained within the preset range, thereby avoiding the excessively high speed of the main shaft 23 causing the generator 24 to generate large current fluctuations, resulting in an unstable rate of hydrogen production in the electrolytic box 1, thereby increasing the production cost of hydrogen production.
