Description

Technical Field

[0001] This utility model relates to the field of hydrogen storage device technology, specifically a hydrogen storage device for solar-powered hydrogen production. Background Technology

[0002] With the acceleration of industrialization, energy consumption is increasing daily. The reliance on fossil fuels as the primary energy source has led to severe environmental pollution and energy shortages. Hydrogen combustion is pollution-free, has a high calorific value, and is an environmentally friendly clean energy source with broad prospects for replacing fossil fuels. Water, as an abundant renewable energy source, is one of the important raw materials for producing hydrogen and oxygen. Electrolysis of water to produce hydrogen and oxygen has the characteristics of high-efficiency reduction power and clean hydrogen evolution, making it a promising method. Currently, hydrogen production is being carried out using solar energy, which is green and environmentally friendly. Solar power is used to generate electricity, which is then used to electrolyze water to produce hydrogen and oxygen. The hydrogen and oxygen are then stored in tanks.

[0003] Based on the above, the inventors have discovered the following problems: Current hydrogen storage devices simply connect hydrogen pipelines to gas tanks. The gas tank inlet is not easy to seal quickly. When the pipeline is disassembled after hydrogen storage is completed, hydrogen is very easy to leak. Hydrogen is flammable and explosive. After leakage, it mixes with air to form a flammable mixture. If it encounters a source of ignition, it may cause combustion or even explosion, which seriously threatens the safety of personnel.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide a hydrogen storage device for solar-powered hydrogen production, in order to achieve a more practical value. Utility Model Content

[0005] The purpose of this invention is to provide a hydrogen storage device for solar-powered hydrogen production, in order to solve the problems mentioned in the background art.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A hydrogen storage device for solar-powered hydrogen production includes an installation component, a storage component, and a sealing component. The storage component is disposed inside the installation component, and the sealing component is disposed below the storage component. The storage component is used to store hydrogen, and the sealing component is used to seal the storage component. The sealing component includes a connecting pipe, a connecting plate is installed on one side of the connecting pipe, and a connecting seat is installed on the side of the connecting plate away from the connecting pipe. A conical chamber is formed inside the connecting seat, and a magnetic ball is disposed inside the conical chamber. A first electromagnet is installed on the inner wall of the conical chamber at the end away from the connecting plate. The first electromagnet and the magnetic ball are magnetically attracted to each other. A hydrogen inlet pipe is connected to the bottom end of the connecting seat near the first electromagnet. The storage component includes a hydrogen storage tank, and an air inlet is formed at the bottom end of the hydrogen storage tank. A flow meter is installed at the bottom end of the hydrogen storage tank at the air inlet, and the flow meter is fixedly connected to the upper end of the connecting pipe at the end away from the hydrogen storage tank.

[0008] Furthermore, the connecting seat has an installation groove inside one end near the connecting plate, and a second electromagnet is installed inside the installation groove. The second electromagnet and the magnetic ball are magnetically attracted to each other. The first electromagnet is energized, and the second electromagnet is de-energized.

[0009] The beneficial effect of adopting the above-mentioned further solution is that by setting a first electromagnet and a second electromagnet, the first electromagnet attracts the magnetic ball when energized, which can maintain the sealing state of the sealing component and prevent hydrogen leakage. The second electromagnet does not affect the attraction of the magnetic ball by the first electromagnet when it is not energized. When it is necessary to allow hydrogen to enter the storage component, the first electromagnet is no longer energized, so that the magnetic ball slides down to the connecting plate under the action of the conical cavity. The second electromagnet is energized and attracts the magnetic ball, so that the magnetic ball no longer seals the conical cavity.

[0010] Furthermore, the connecting plate has several air holes, and the connecting pipe, connecting plate, connecting seat and hydrogen inlet pipe are interconnected.

[0011] The beneficial effect of adopting the above-mentioned further scheme is that, since several air holes are opened on the connecting plate, and the hydrogen inlet pipe, the connecting seat, the connecting plate and the connecting pipe are connected, hydrogen can enter the interior of the hydrogen storage tank through the conical chamber in the hydrogen inlet pipe and the connecting seat, the connecting plate and the connecting pipe.

[0012] Furthermore, a circular hole is provided on one side of the outer wall of the hydrogen storage tank, and a pressure gauge is installed inside the circular hole, with the sensing end of the pressure gauge located inside the hydrogen storage tank.

[0013] The beneficial effect of adopting the above-mentioned further solution is that by setting up a pressure gauge with the sensing end of the pressure gauge located inside the hydrogen storage tank, the hydrogen pressure inside the hydrogen storage tank can be monitored in real time. When the pressure is too high or too low, the operator can detect it in time by visually inspecting the pressure gauge.

[0014] Furthermore, the mounting assembly includes a base, a high-pressure air pump is mounted on one side of the top surface of the base, a hose is mounted on the outlet end of the high-pressure air pump, a threaded connector is connected to the end of the hose away from the high-pressure air pump, and the inner wall of the hydrogen inlet pipe is provided with several threads, and the threaded connector is threadedly connected to the hydrogen inlet pipe.

[0015] The beneficial effect of adopting the above-mentioned further solution is that by setting up a high-pressure gas pump and connecting the inlet end of the high-pressure gas pump to the hydrogen pipe of the solar hydrogen production device through a pipeline, when the high-pressure gas pump is started, the high-pressure gas pump can provide sufficient pressure for the delivery of hydrogen, so that the hydrogen can smoothly enter the hydrogen storage tank. By setting up a hose, it is easy to connect the high-pressure gas pump and the hydrogen inlet pipe. Since one end of the hose is equipped with a threaded joint, the threaded joint is connected to the threaded hydrogen inlet pipe, which facilitates the assembly and disassembly of the hose and the hydrogen inlet pipe.

[0016] Furthermore, a reinforcing seat is installed on the upper end of the base, and a bottom ring is installed on the outside of the reinforcing seat. The hydrogen storage tank is located on the upper end of the bottom ring, and the bottom surface of the hydrogen storage tank is in contact with the top surface of the bottom ring. A bracket is installed on the top surface of the reinforcing seat, and a ball screw is provided between the bracket and the reinforcing seat. The two ends of the ball screw are respectively connected to the inner top surface of the bracket and the top surface of the reinforcing seat through bearings. A lifting frame is threaded to the outside of the ball screw. One end of the lifting frame is connected to a top ring, and the bottom end of the top ring is in contact with the top surface of the hydrogen storage tank. A pair of sliding grooves are opened at the end of the lifting frame away from the top ring. Each pair of sliding grooves is provided with a sliding strip inside. One side of each pair of sliding strips is fixedly connected to one side of the inner wall of the bracket, and the outer wall of the sliding strip slides in contact with the inner wall of the sliding groove.

[0017] The beneficial effect of adopting the above-mentioned further solution is that, by setting a reinforcing seat and a bottom ring, the hydrogen storage tank is placed on the bottom ring. The reinforcing seat and the bottom ring provide stable support for the hydrogen storage tank. Through the coordinated use of the ball screw, slide bar, slide groove and lifting frame, when the ball screw rotates, the lifting frame connected by its external thread moves linearly under the action of the slide groove and slide bar, thereby adjusting the position of the lifting frame and the top ring. When the hydrogen storage tank needs to be removed, the lifting frame moves upward, causing the top ring to move upward, increasing the distance between the top ring and the bottom ring. When the hydrogen storage tank needs to be installed, the lifting frame moves downward, causing the top ring to move downward, decreasing the distance between the top ring and the bottom ring, so that the hydrogen storage tank is limited and fixed between the bottom ring and the top ring.

[0018] Furthermore, a servo motor is mounted on the top surface of the bracket, and the output end of the servo motor is fixedly connected to the ball screw. Mounting holes are provided at the four corners of the base.

[0019] The beneficial effect of adopting the above-mentioned further solution is that by setting a servo motor, when the servo motor is working, it drives the ball screw to rotate, and by opening mounting holes at the four corners inside the base, it is easy to install the base in a designated position by bolt fasteners.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: This solar-powered hydrogen storage device connects the inlet of a high-pressure gas pump to the hydrogen pipe of the solar-powered hydrogen production device via a pipeline. A conical chamber is designed, with the inner diameter of the end near the connecting plate being larger than the inner diameter of the end away from the connecting plate. A magnetic ball is located inside the conical chamber at the end away from the connecting plate. Since the first electromagnet is energized and the second electromagnet is de-energized, the first electromagnet attracts the magnetic ball, which then seals the conical chamber. When hydrogen needs to be allowed to enter for storage... During assembly, the first electromagnet is de-energized, causing the magnetic ball to slide down into the conical chamber and reach the connecting plate. The second electromagnet is then energized, attracting the magnetic ball and preventing it from blocking the conical chamber. This allows operators to easily monitor the rate and total amount of hydrogen storage. A flexible hose facilitates connection to the high-pressure gas pump and hydrogen inlet pipe. When the high-pressure gas pump is started, it provides sufficient pressure for hydrogen delivery. Several air holes are opened on the connecting plate, and the hydrogen inlet pipe, connecting seat, connecting plate, and connecting pipe are interconnected, allowing hydrogen to pass through... Hydrogen gas enters the hydrogen storage tank through the hydrogen inlet pipe, the conical chamber within the connecting seat, the connecting plate, and the connecting pipe. A flow meter installed at the bottom of the storage tank allows for real-time monitoring of the hydrogen flow rate. A pressure gauge, with its sensing end located inside the storage tank, allows for real-time monitoring of the internal hydrogen pressure. Operators can visually detect excessively high or low pressure readings by checking the pressure gauge. After hydrogen injection is complete, the high-pressure gas pump is shut off, the first electromagnet is energized, and the second electromagnet is de-energized. The first electromagnet attracts the magnetic ball. At this time, the magnetic ball seals the conical chamber to prevent leakage when the hose is disassembled from the hydrogen inlet pipe. Since one end of the hose is equipped with a threaded connector, which is connected to the threaded hydrogen inlet pipe, it is easy to disassemble the hose and the hydrogen inlet pipe. When the servo motor works, it drives the ball screw to rotate. The lifting frame connected to its external thread moves linearly under the action of the slide groove and slide bar, thereby adjusting the position of the lifting frame and the top ring. When the hydrogen storage tank needs to be removed, the lifting frame moves up, causing the top ring to move up, thus increasing the distance between the top ring and the bottom ring.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5This utility model provides a technical solution: a hydrogen storage device for solar-powered hydrogen production, comprising an installation component 1, a storage component 2, and a sealing component 3. The storage component 2 is disposed inside the installation component 1, and the sealing component 3 is disposed below the storage component 2. The storage component 2 is used to store hydrogen, and the sealing component 3 is used to seal the storage component 2. The sealing component 3 includes a connecting pipe 31, a connecting plate 32 is installed on one side of the connecting pipe 31, and a connecting seat 33 is installed on the side of the connecting plate 32 away from the connecting pipe 31. A conical cavity 34 is formed inside the connecting seat 33, and a magnetic ball 35 is disposed inside the conical cavity 34. A first electromagnet 36 is installed on the inner wall of the conical cavity 34 at the end away from the connecting plate 32. The first electromagnet 36 and the magnetic ball 35 are magnetically connected. Attracted, the bottom end of the connecting seat 33 is connected to a hydrogen inlet pipe 38 near the first electromagnet 36. The storage component 2 includes a hydrogen storage tank 21, with an air inlet at the bottom end of the hydrogen storage tank 21. A flow meter 22 is installed at the air inlet at the bottom end of the hydrogen storage tank 21. The end of the flow meter 22 away from the hydrogen storage tank 21 is fixedly connected to the upper end of the connecting pipe 31. A conical chamber 34 is provided, with the inner diameter of the end of the conical chamber 34 near the connecting plate 32 being larger than the inner diameter of the end away from the connecting plate 32. A magnetic ball 35 is located inside the end of the conical chamber 34 away from the connecting plate 32. Since the first electromagnet 36 is energized and the second electromagnet 37 is de-energized at this time, the first electromagnet 36 attracts the magnetic ball 35, and the magnetic ball 35 blocks the conical chamber 34.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-5This utility model provides a technical solution: A mounting groove is formed inside the connecting seat 33 at one end near the connecting plate 32. A second electromagnet 37 is installed inside the mounting groove. The second electromagnet 37 and the magnetic ball 35 are magnetically attracted. The first electromagnet 36 is energized, and the second electromagnet 37 is de-energized. Several air holes are formed on the connecting plate 32. The connecting pipe 31, connecting plate 32, connecting seat 33, and hydrogen inlet pipe 38 are interconnected. A circular hole is formed on one side of the outer wall of the hydrogen storage tank 21. A pressure gauge 23 is installed inside the circular hole. The sensing end of the pressure gauge 23 is located inside the hydrogen storage tank 21. By setting the first electromagnet 36 and the second electromagnet 37, the first electromagnet 36, when energized, attracts the magnetic ball 35, maintaining the sealing state of the sealing assembly 3 and preventing hydrogen leakage. The second electromagnet 37, when de-energized, does not affect the attraction of the magnetic ball 35 by the first electromagnet 36. An electromagnet 36 attracts hydrogen gas. When hydrogen needs to enter the storage component 2, the first electromagnet 36 is de-energized, causing the magnetic ball 35 to slide down to the connecting plate 32 under the action of the conical chamber 34. The second electromagnet 37 is energized and attracts the magnetic ball 35, so that the magnetic ball 35 no longer blocks the conical chamber 34. Since several air holes are opened on the connecting plate 32, and the hydrogen inlet pipe 38, the connecting seat 33, the connecting plate 32 and the connecting pipe 31 are connected, hydrogen gas enters the interior of the hydrogen storage tank 21 through the hydrogen inlet pipe 38, the conical chamber 34 in the connecting seat 33, the connecting plate 32 and the connecting pipe 31. By setting a pressure gauge 23, the sensing end of the pressure gauge 23 is located inside the hydrogen storage tank 21, and the hydrogen pressure inside the hydrogen storage tank 21 can be monitored in real time. When the pressure is too high or too low, the operator can detect it in time by visually inspecting the pressure gauge 23.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-5This utility model provides a technical solution: the mounting assembly 1 includes a base 11, a high-pressure air pump 12 is mounted on one side of the top surface of the base 11, a hose 13 is mounted on the outlet end of the high-pressure air pump 12, a threaded connector is connected to the end of the hose 13 away from the high-pressure air pump 12, the inner wall of the hydrogen inlet pipe 38 is provided with several threads, and the threaded connector is threadedly connected to the hydrogen inlet pipe 38, a reinforcing seat 14 is mounted on the upper end of the base 11, a bottom ring 15 is mounted on the outside of the reinforcing seat 14, a hydrogen storage tank 21 is disposed on the upper end of the bottom ring 15, the bottom surface of the hydrogen storage tank 21 is in contact with the top surface of the bottom ring 15, a bracket 16 is mounted on the top surface of the reinforcing seat 14, and a ball screw is provided between the bracket 16 and the reinforcing seat 14. The ball screw 17 is connected at both ends to the inner top surface of the bracket 16 and the top surface of the reinforcing seat 14 via bearings. A lifting frame 18 is threaded onto the outer side of the ball screw 17. One end of the lifting frame 18 is connected to a top ring 110, the bottom end of which is in contact with the top surface of the hydrogen storage tank 21. A pair of sliding grooves are provided at the end of the lifting frame 18 furthest from the top ring 110. Each of the sliding grooves contains a sliding strip 19. One side of each sliding strip 19 is fixedly connected to one side of the inner wall of the bracket 16. The outer wall of the sliding strip 19 slides against the inner wall of the sliding groove. A servo motor 111 is mounted on the top surface of the bracket 16, and the output end of the servo motor 111 is fixedly connected to the ball screw 17. Mounting holes are provided at the four corners of the base 11. A high-pressure gas pump 12 is installed, and its inlet is connected to the hydrogen pipe of the solar hydrogen production device via a pipe. When the high-pressure gas pump 12 is started, it provides sufficient pressure for the hydrogen delivery, allowing the hydrogen to smoothly enter the hydrogen storage tank 21. A flexible hose 13 is provided to facilitate the connection between the high-pressure gas pump 12 and the hydrogen inlet pipe 38. Since one end of the flexible hose 13 has a threaded connector, which connects to the threaded connection of the hydrogen inlet pipe 38, it is easy to assemble and disassemble the flexible hose 13 and the hydrogen inlet pipe 38. The hydrogen storage tank 21 is placed on the bottom ring 15 by a reinforcing seat 14 and a bottom ring 15. The bottom ring 15 and the bottom ring 14 provide stable support for the hydrogen storage tank 21. A servo motor 111 is installed so that when the servo motor 111 is working, it drives the ball screw 17 to rotate. The lifting frame 18, which is externally threaded to the ball screw 17, moves linearly under the action of the slide groove and the slide bar 19, thereby adjusting the position of the lifting frame 18 and the top ring 110. When the hydrogen storage tank 21 needs to be removed, the lifting frame 18 moves upward, causing the top ring 110 to move upward, thus increasing the distance between the top ring 110 and the bottom ring 15. When the hydrogen storage tank 21 needs to be installed, the lifting frame 18 moves downward, causing the top ring 110 to move downward, thus decreasing the distance between the top ring 110 and the bottom ring 15, so that the hydrogen storage tank 21 is limited and fixed between the bottom ring 15 and the top ring 110.

[0033] Specifically, the working principle of this solar-powered hydrogen storage device is as follows: During use, mounting holes are made at the four corners of the base 11 to facilitate installation of the base 11 in the designated position using bolts. The inlet of the high-pressure gas pump 12 is connected to the hydrogen pipe of the solar-powered hydrogen production device via a pipe. A conical chamber 34 is provided, with its inner diameter at the end near the connecting plate 32 being larger than that at the end away from the connecting plate 32. The magnetic ball 35 is located inside the conical chamber 34 at the end away from the connecting plate 32. Since the first electromagnet 36 is energized and the second electromagnet 37 is de-energized, the first electromagnet 36 attracts the magnetic ball 35. At this time, the magnetic ball 35 exerts its force on the conical chamber... Chamber 34 is sealed. When hydrogen needs to enter storage component 2, the first electromagnet 36 is de-energized, causing the magnetic ball 35 to slide down to the connecting plate 32 under the action of the conical chamber 34. The second electromagnet 37 is energized, attracting the magnetic ball 35, so that the magnetic ball 35 no longer seals the conical chamber 34. This allows operators to easily monitor the speed and total amount of hydrogen storage. The flexible hose 13 facilitates connection between the high-pressure gas pump 12 and the hydrogen inlet pipe 38. When the high-pressure gas pump 12 is started, it can provide sufficient pressure for hydrogen delivery. Because several air holes are opened on the connecting plate 32, and the hydrogen inlet pipe 38, connecting seat 33, connecting plate 32 and connecting pipe 31 are connected... The connection allows hydrogen gas to enter the hydrogen storage tank 21 through the hydrogen inlet pipe 38, the conical chamber 34 in the connecting seat 33, the connecting plate 32, and the connecting pipe 31. A flow meter 22 installed at the bottom of the hydrogen storage tank 21 can monitor the hydrogen flow rate in real time. A pressure gauge 23, with its sensing end located inside the hydrogen storage tank 21, can monitor the hydrogen pressure inside the tank in real time. If the pressure is too high or too low, the operator can visually detect it by checking the pressure gauge 23. After hydrogen injection is complete, the high-pressure gas pump 12 is turned off, the first electromagnet 36 is energized, and the second electromagnet 37 is de-energized. The first electromagnet 36 attracts magnets. Ball 35, at this time, blocks the conical chamber 34 to prevent leakage when the hose 13 and hydrogen inlet pipe 38 are disassembled. Since one end of the hose 13 is provided with a threaded connector, the threaded connector is connected to the threaded hydrogen inlet pipe 38, which facilitates the disassembly of the hose 13 and hydrogen inlet pipe 38. When the servo motor 111 works, it drives the ball screw 17 to rotate. The lifting frame 18 connected to its external thread moves linearly under the action of the slide groove and slide bar 19, thereby adjusting the position of the lifting frame 18 and the top ring 110. When the hydrogen storage tank 21 needs to be removed, the lifting frame 18 moves up and drives the top ring 110 to move up, so that the distance between the top ring 110 and the bottom ring 15 increases.
