Description

Technical Field

[0001] The invention relates to the technical field of alkaline water electrolysis hydrogen production equipment, in particular to an assembling device for an electrolytic cell disc spring group and an assembling method thereof. Background Art

[0002] As a clean energy carrier, hydrogen energy is of great significance for promoting sustainable development in fields such as transportation, energy storage and industry.

[0003] At present, the main way to produce hydrogen is through the conversion process of fossil fuels, such as natural gas reforming. This fossil energy-based hydrogen production will produce a large amount of greenhouse gases, especially carbon dioxide. This hydrogen is often called "grey hydrogen". In order to get rid of dependence on fossil fuels and significantly reduce carbon emissions, it is urgent to increase the proportion of hydrogen production using renewable energy. By using renewable energy such as solar photovoltaic power generation and wind power generation to drive the process of water electrolysis, the so-called "green hydrogen" can be produced. The production of this green hydrogen not only does not produce greenhouse gas emissions, but also helps to achieve energy decarbonization. With the maturity and cost reduction of renewable energy technology, as well as the advancement of water electrolysis technology, green hydrogen is expected to play an increasingly important role in energy transformation.

[0004] Since the alkaline electrolyzer is relatively large in size and heavy in weight, it can only be assembled vertically due to the product characteristics, which inevitably requires the installation of disc springs, guide sleeves, guide rings, etc. at one end. Due to the heavy weight of the disc spring assembly, it is difficult to install it manually. Therefore, after the tension screw of the alkaline electrolyzer is installed, it is difficult to install the nut, and there are safety hazards, which affects the assembly quality and speed. Summary of the invention

[0005] The embodiment of the present application provides an assembly device for an electrolytic cell disc spring group and an assembly method thereof to solve the problems of difficult operation and high safety hazards in the prior art when assembling the electrolytic cell disc spring group, thereby improving the assembly quality and assembly speed.

[0006] In order to solve the above technical problems, the present invention adopts the following technical scheme: an assembly device for an electrolytic cell disc spring group, including a load-bearing mechanism and a tightening mechanism. The load-bearing mechanism includes a load-bearing tray and a retaining frame fixed to the load-bearing tray, and the retaining frame is located above the load-bearing tray; a through hole is provided in the center of the load-bearing tray running through the top and bottom, and the tightening mechanism is located below the through hole.

[0007] When using this device to assemble the disc spring assembly of the electrolytic cell, the disc spring assembly and the guide sleeve, gasket, insulating pad and other components can be placed in the retaining frame on the load-bearing tray in order. After the tensioning screw passes through the relevant components in turn, it can pass through the through hole on the load-bearing tray, and finally the nut can be tightened at the lower end of the tensioning screw using the handle. In this process, the tray can maintain the pushing force on each component, thereby reducing the operating intensity, improving safety, and improving the assembly quality and assembly speed.

[0008] Furthermore, the load-bearing mechanism also includes a support beam, a jack and a support seat, wherein the support beam is fixedly connected to one side of the load-bearing tray, the upper end of the jack is supported below the support beam, and the lower end of the jack is fixed to the support seat; the jack can provide an upward thrust to drive the support beam to move, thereby lifting the disc spring group. This not only reduces the labor intensity of the operator, but also improves the safety of the operation.

[0009] Furthermore, the jack is connected to a high-pressure oil pump via a high-pressure oil pipe.

[0010] Furthermore, the high-pressure oil pump is connected to a remote controller via a data transmission line; thus, through the remote controller, the operator can remotely control the switch and pressure adjustment of the high-pressure oil pump, thereby realizing remote control of the jack, improving the flexibility and safety of operation.

[0011] Furthermore, the retaining frame includes a plurality of vertically arranged columns, which are arranged at equal intervals and distributed in a circle around the center of the load-bearing tray.

[0012] Furthermore, the diameter of the through hole on the load-bearing tray is larger than the outer diameter of the tensioning screw on the electrolytic cell, and the diameter of the through hole on the load-bearing tray is smaller than the diameter of the disc spring assembly.

[0013] Furthermore, the tightening mechanism includes a handle, and a positioning sleeve capable of cooperating with the nut is arranged at the end of the handle; a ratchet is also arranged between the positioning sleeve and the handle.

[0014] The present invention also discloses a method for assembling an electrolytic cell disc spring assembly, which uses the above-mentioned device for assembling an electrolytic cell disc spring assembly and specifically comprises the following steps: S1. Place the disc spring assembly, guide sleeve, gasket and insulating pad in the retaining frame on the load-bearing tray; S2. Use the load-bearing mechanism to transmit the lifting force upward to lift the disc spring assembly; S3. When the upper end of the disc spring assembly is in contact with the pressure plate surface at the lower end of the electrolytic cell body, the tensioning screw is passed through the insulating pad, gasket, disc spring assembly, guide sleeve, and nut below the electrolytic cell body in sequence; S4. Tighten the nut using a tightening mechanism.

[0015] It can be seen from the above technical solutions that the present invention has at least the following technical effects or advantages: 1. When using this device to assemble the disc spring assembly of the electrolytic cell, the disc spring assembly and the guide sleeve, gasket, insulating pad and other components can be placed in the retaining frame on the load-bearing tray in order. After the tensioning screw passes through the relevant components in turn, it can pass through the through hole on the load-bearing tray, and finally use the handle to tighten the nut at the lower end of the tensioning screw. In this process, the tray can maintain the pushing force on each component, thereby reducing the operating intensity, improving safety, and improving the assembly quality and assembly speed.

[0016] 2. Use a jack to support the bottom of the support beam. The jack provides an upward thrust to drive the support beam to move, so as to lift the disc spring group. This not only reduces the labor intensity of the operator, but also improves the safety of the operation.

[0017] 3. The jack is hydraulically driven and the high-pressure oil pump is connected to a remote control through a data transmission line. Therefore, through the remote control, the operator can remotely control the switch and pressure adjustment of the high-pressure oil pump, thereby realizing remote control of the jack and improving the flexibility and safety of operation.

DETAILED DESCRIPTION

[0020] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0021] The present invention discloses an assembly device for an electrolytic cell disc spring assembly, which includes a load-bearing mechanism and a tightening mechanism. The load-bearing mechanism is used to support an insulating pad 17, a gasket 16, a disc spring assembly 15 and a guide sleeve 14 below an electrolytic cell body 19. When a tightening screw 18 passes through the insulating pad 17, the gasket 16, the disc spring assembly 15 and the guide sleeve 14 in sequence, the tightening mechanism can drive a nut 13 to be tightened by the lower end of the tightening screw 18.

[0022] like Figure 1 As shown, the load-bearing mechanism includes a load-bearing tray 1 and a retaining frame 2 located on the load-bearing tray 1. The load-bearing tray 1 is flat, and a through hole is provided at the center of the load-bearing tray 1, which runs through the upper and lower parts. The provision of the through hole enables the lower end of the tightening screw 18 to pass through the load-bearing tray 1, so as to facilitate the manipulation of the tightening mechanism to tighten the nut 13 on the lower end of the tightening screw 18. Specifically, the diameter of the through hole on the load-bearing tray 1 is larger than the outer diameter of the tightening screw 18 on the electrolytic cell, thereby ensuring that the lower end of the tightening screw 18 can smoothly pass through the load-bearing tray 1. In addition, the diameter of the through hole on the load-bearing tray 1 is smaller than the outer diameter of the disc spring, thereby ensuring that the load-bearing tray 1 plays a role in supporting the disc spring. It should be understood that the diameter of the through hole is larger than the maximum size of the nut.

[0023] The retainer 2 is arranged above the load-bearing tray 1. In the present embodiment, the retainer 2 comprises a plurality of vertically arranged columns, which are arranged at equal intervals above the load-bearing tray 1 and are distributed in a circle around the center of the load-bearing tray 1. When the load-bearing tray 1 supports the disc spring assembly 15 above it, there is a small gap between the outer periphery of the disc spring assembly 15 and the retainer 2, thereby enabling the disc spring assembly 15 to maintain the correct position during the assembly process and avoid misalignment. In other embodiments, the retainer 2 may be a cylindrical shape that penetrates from top to bottom.

[0024] like Figure 2As shown, the load-bearing mechanism also includes a support beam 3, a support seat 4 and a jack 5. The support beam 3 is arranged horizontally, and one end of the support beam 3 is fixedly connected to one side of the load-bearing tray 1, so that when the position of the support beam 3 rises, the position of the load-bearing tray 1 can be driven to rise accordingly, thereby lifting the disc spring group 15 upward. It should be understood that the other end of the support beam 3 can be connected to a fixed object to form a lever mechanism, or a heavy object can be placed at the other end of the support beam 3 to keep the support beam 3 balanced. The force can be transmitted to the load-bearing tray 1 through the support beam 3, so that there is enough operating space under the load-bearing tray 1, which is convenient for tightening the nut 13 on the lower end of the tightening screw 18.

[0025] The support seat 4 and the jack 5 are both installed below the support beam 3. The lower end of the jack 5 is fixed to the support seat 4 to maintain the stability of the jack 5. The upper end of the jack 5 is connected to the lower bottom surface of the support beam 3, so that when the jack is extended, it can drive the load-bearing tray 1 to move upward, thereby supporting the disc spring group 15.

[0026] The jack 5 is hydraulically driven. Figure 1 As shown, the hydraulic interface of the jack 5 is connected to a high-pressure oil pipe 9, and the other section of the high-pressure oil pipe 9 is connected to a high-pressure oil pump 10. The high-pressure oil pump 10 can pump hydraulic oil into the high-pressure oil pipe 9, thereby providing high-pressure hydraulic oil for the jack 5, and then driving the jack 5 to provide lifting force. In addition, the high-pressure oil pump 10 is also connected to a remote controller 12 through a data transmission line 11, so that the operator can remotely control the switch and pressure adjustment of the high-pressure oil pump 10 through the remote controller 12, thereby realizing remote control of the jack 5, improving the flexibility and safety of operation. Among them, the jack 5 is a commercially available product, and the jack 5 can be remotely controlled through the high-pressure oil pipe 9 and the high-pressure oil pump 10, which is also a prior art, and is well known to those skilled in the art, so it will not be repeated.

[0027] like Figure 1 As shown, the tightening mechanism is located below the load-bearing tray 1. In this embodiment, the tightening mechanism is an existing tightening tool, which includes a handle 6, a positioning sleeve 8, and a ratchet 7 located between the handle 6 and the positioning sleeve 8. Among them, the positioning sleeve 8 is installed and fixed at one end of the handle 6, and its function is to cooperate with the nut 13. When the ratchet 7 is turned, the positioning sleeve 8 can clamp or loosen the nut 13 through the forward or reverse rotation of the ratchet 7. When the nut 13 is clamped by the positioning sleeve 8, the nut 13 can be tightened by rotating the handle 6.

[0028] The present invention also discloses an assembly method of an electrolytic cell disc spring assembly, which adopts the above device and specifically comprises the following steps: S1, place the disc spring assembly 15, the guide sleeve 14, the gasket 16, and the insulating pad 17 in the retaining frame 2 on the load-bearing tray 1; S2, using the load-bearing mechanism to transmit the lifting force upward to lift the disc spring assembly 15; S3. When the upper end of the disc spring assembly 15 is in contact with the pressure plate surface at the lower end of the electrolytic cell body 19, the tensioning screw 18 passes through the insulating pad 17, the gasket 16, the disc spring assembly 15, the guide sleeve 14, and the nut 13 below the electrolytic cell body 19 in sequence; S4. Tighten the nut 13 using a tightening mechanism.
