Description

Technical Field

[0001] The invention relates to the technical field of water electrolysis, in particular to an electrolytic cell protective structure. Background Art

[0002] Water electrolysis is a relatively convenient method for producing hydrogen. Direct current is passed through an electrolytic cell filled with potassium hydroxide or sodium hydroxide, causing water molecules to undergo an electrochemical reaction at the electrodes, decomposing into hydrogen and oxygen. The electrolysis process takes place within the electrolytic cell, which consists of a cell body, an anode, and a cathode. A diaphragm often separates the anode and cathode compartments. A fixed top cover encloses the cell, which is equipped with terminals connecting the cathode and anode, as well as an exhaust pipe. When direct current passes through the cell, an oxidation reaction occurs at the anode-solution interface, and a reduction reaction occurs at the cathode-solution interface, producing the desired product.

[0003] Due to the thermal effect of the electric current, the temperature of the electrolyte will gradually increase, and the electrolysis temperature is generally controlled at 90±5℃. However, the existing water electrolysis hydrogen production system may encounter external factors such as insufficient power supply and power restrictions, as well as internal factors such as process, instrumentation, and equipment failures, which lead to frequent chain adjustments of the electrolytic cell device. The temperature of the electrolytic cell decreases due to long-term shutdown, and when it is restarted, the temperature gradually increases. In general, if the electrolytic cell is started and stopped frequently, the internal cavity of the electrolytic cell will expand or contract due to thermal expansion and contraction, causing the space to shrink or expand. The connection between the electrolytic cell and the top cover will deform due to the thermal expansion and contraction of the internal cavity, resulting in damage to the connection between the electrolytic cell and the top cover, causing gas and liquid leakage, and shortening the operation cycle. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the prior art, the object of the present invention is to:

[0005] An electrolytic cell protection structure, the key of which is to include:

[0006] An electrolytic cell body, wherein the electrolytic cell body is open at the top and hollow inside; an ion diaphragm is fixed in the hollow position inside the electrolytic cell body;

[0007] A top cover is provided to cover the top opening of the electrolytic cell body along a first direction; an electrode sheet structure is fixed below the top cover, and the electrode sheet structure extends into the electrolytic cell body.

[0008] a compensation assembly, sealed between the top cover and the top opening of the electrolytic cell body;

[0009] The compensation assembly includes a guide tube and a corrugated expansion tube fixed on the lower end surface of the top cover; the guide tube extends in the first direction along the inner wall of the electrolytic cell body and is fixedly connected to the top end of the corrugated expansion tube, a first annular mounting plate is fixed to the outer periphery of the bottom end of the corrugated expansion tube, a second annular mounting plate is fixed to the outer periphery of the top of the electrolytic cell body, the first annular mounting plate is fixedly connected to the second annular mounting plate, and the top cover and the first annular mounting plate are fixedly connected via a constraint assembly.

[0010] Through the above implementation method, when the inner cavity of the electrolytic cell body expands and contracts due to thermal expansion and contraction, the compensation component can compensate for the contraction and expansion of the space caused by the thermal expansion and contraction, prevent the air pressure from having an excessive effect on the top cover, and compensate for the connection between the electrolytic cell body and the top cover, thereby reducing the possibility of the inner cavity of the electrolytic cell body impacting and damaging the connection between the electrolytic cell body and the top cover, thereby reducing the possibility of deformation and leakage at the connection, and improving the safety of the device.

[0011] Specifically, thermal expansion and contraction cause the inner cavity of the electrolytic cell to shrink and expand, which will drive the first annular mounting plate fixedly connected to the electrolytic cell body to move in a first direction. The movement of the first annular mounting plate will drive the bellows to expand and contract and deform. The deformation and movement of the bellows compensates for the connection between the top cover and the electrolytic cell body, reducing the possibility of leakage at the connection between the electrolytic cell body and the top cover. The restraint component can adjust the expansion and contraction amount of the bellows and play a certain supporting role. When the device is not put into use, the bellows needs to be temporarily restrained.

[0012] In one implementation, the constraint assembly includes a third annular mounting plate sleeved on the outer peripheral side wall of the top cover, a first ear plate is fixed at the four end corners of the outer periphery of the third annular mounting plate, a second ear plate directly below the first ear plate is fixed at the four end corners of the outer periphery of the first annular mounting plate, circular holes are opened on the first ear plate and the second ear plate, screws are passed through the circular holes on the first ear plate and the adjacent second ear plate, the top and bottom ends of the screws pass through the first ear plate and the second ear plate respectively, the parts of the screws passing through the first ear plate and the second ear plate are both provided with nuts through threaded sleeves, and the two nuts respectively interfere with the first ear plate and the second ear plate.

[0013] Through the above implementation method, when the corrugated expansion tube needs to be temporarily constrained, the screw is passed through the first ear plate and the second ear plate from top to bottom in sequence, and the two ends of the screw pass through the first ear plate and the second ear plate respectively, and the parts of the screw passing through the first ear plate and the second ear plate are both provided with nuts through threaded sleeves, and the two nuts respectively contact the first ear plate and the second ear plate. Through the action of the nuts and the screw, the first ear plate and the second ear plate are fixedly connected.

[0014] In one implementation, a guide assembly is provided between the first ear plate and the first annular mounting plate to guide the movement of the second ear plate. There are two guide assemblies, and the two guide assemblies are symmetrically arranged.

[0015] Through the above-mentioned implementation method, through the action of the guide component in the first direction, when the bellows expansion tube undergoes expansion and contraction deformation, it plays a guiding role in the expansion and contraction deformation of the bellows expansion tube, so that the expansion and contraction deformation amounts at the left and right ends of the bellows expansion tube are consistent, thereby reducing the possibility that the electrode sheet structure may damage the inner wall of the electrolytic cell body and cause damage to the electrode sheet structure due to the inconsistent expansion and contraction deformation amounts at the left and right ends of the bellows expansion tube.

[0016] The top end face of said sliding panel also is provided with an interlock plate, and the interlock plate is fixed with a toothed connection between the end face of said interlock plate and the interlock plate, and the interlock plate is fixed with a toothed connection between the end face of said interlock plate and the interlock plate.

[0017] Through the above implementation method, when one end of the corrugated expansion tube produces expansion and contraction deformation while the other end does not produce expansion and contraction deformation, the expansion and contraction deformed end will drive one end of the top cover to move, and the movement of one end of the top cover will drive the guide column at that end to move in the vertical direction. The movement of the guide column will drive the rack fixedly connected to the guide column to move, and the movement of the rack will drive the gear meshing with the rack to rotate, and the rotation of the gear will drive the transmission shaft fixedly connected to the gear to rotate, and the rotation of the transmission shaft will drive another gear fixedly connected to the transmission shaft to rotate, and then drive the adjacent rack and guide column to move in the vertical direction, so that the left and right ends of the top cover move at the same time, reducing the possibility of the electrode sheet structure tilting due to the movement of one end of the top cover.

[0018] In one implementation, a protective box body is provided on the outer side of the electrolytic cell body to protect the electrolytic cell body, and the protective box body is fixedly connected to the top cover.

[0019] Through the above implementation method, the electrolytic cell body is placed inside the protective box body, which protects the electrolytic cell body and reduces the impact of external dust, oil, etc. on the electrolytic cell body. The protective box body is detachably fixed to the top cover, which does not affect the disassembly and assembly of the protective box body.

[0020] In one implementation, a heat-insulating sleeve for reducing the arc of temperature difference change is fixed to the inner periphery of the protection box body, and anti-collision components are provided on the four outer sides of the protection box body.

[0021] Through the above implementation method, the insulation sleeve plays an insulating role on the electrolytic cell body, reducing the possibility of thermal expansion and contraction of the electrolytic cell body, thereby reducing the possibility of deformation and penetration of the electrolytic cell body, improving the safety of the device, and reducing the damage to the electrolytic cell body and the protective box body caused by external impact through the anti-collision component, thereby improving the service life and service life of the device, and facilitating the transportation of the electrolytic cell body and the protective box body.

[0022] In one implementation, the anti-collision component includes a guide rail fixedly connected to the outer periphery of the protective box body, and two first sliders and two second sliders are slidably connected to the guide rail. The two first sliders and the second sliders are symmetrically distributed around the center position of the guide rail. An arc-shaped outer guard plate is fixed between two adjacent first sliders, and an arc-shaped inner guard plate is fixed between two adjacent second sliders. The arc-shaped inner guard plate and the arc-shaped outer guard plate are both protruded toward the outside of the protective box body, and the arc-shaped inner guard plate and the arc-shaped outer guard plate are both elastic.

[0023] Through the above-mentioned implementation method, when the outside world collides with the curved inner guard plate and the curved outer guard plate, the curved inner guard plate and the curved outer guard plate will be deformed in turn, and respectively drive the second slider fixedly connected to the curved inner guard plate and the first slider fixedly connected to the curved outer guard plate to slide on the guide rail, thereby producing a buffering effect. The impacting object will also produce a reaction force under the action of the curved inner guard plate and the curved outer guard plate, resulting in deceleration and turning, thereby reducing the damage to the protective box body.

[0024] In one implementation, anti-slip plates are fixed to both ends of the guide rail, reinforcing ribs are fixed at the connection between the anti-slip plates and the guide rails, and a rubber anti-collision block is fixed to the side of the anti-slip plate close to the first slider.

[0025] Through the above implementation method, by arranging anti-slip plates at both ends of the guide rail, the possibility of the first slider and the second slider falling off the guide rail is reduced, and by arranging reinforcing ribs at the connection between the guide rail and the anti-slip plate, the connection strength of the anti-slip plate is improved. The action of the rubber anti-collision block reduces the possibility of the first slider colliding with the anti-slip plate and causing damage to the anti-slip plate.

[0026] In one implementation, a first base plate is fixed to the bottom end of the protective box body, a spirit level located next to the protective box body is fixed to the upper surface of the first base plate, a second base plate is arranged directly below the first base plate, a rubber pad is fixed to the bottom end of the second base plate, and the first base plate and the second base plate are fixedly connected by a leveling structure.

[0027] Through the above implementation, the rubber pad can reduce the impact of the electrolytic cell body on the electrolytic cell body during transportation and placement. A number of axial guide columns are fixed at the middle position between the first bottom plate and the second bottom plate. The guide columns include a sleeve column and an extension column. The bottom end of the sleeve column is fixedly connected to the upper surface of the second bottom plate, and the extension column is slidably connected inside the sleeve column. One end of the extension column extending out of the sleeve column is fixedly connected to the lower end surface of the first bottom plate. The first bottom plate is supported by the several guide columns, and the first and second bottom plates are conveniently fixedly connected. A certain gap is formed between the first and second bottom plates, which facilitates the forklift to carry the protective box body and the electrolytic cell body, reducing damage to the outer surface of the electrolytic cell body by the lifting rope. When the second bottom plate is placed on an uneven ground or operating table, it can be seen through the spirit level that the protective box body and the electrolytic cell body are not in a horizontal state. At this time, the protective box body is leveled by the leveling structure, reducing the possibility of uneven electrolysis of water on the left and right sides of the electrolytic cell body causing a pressure difference on both sides of the ion diaphragm and a decrease in gas purity.

[0028] In one implementation, the leveling structure includes a horizontally arranged connecting plate, the connecting plate is fixedly connected to the second base plate, the bottom end of the connecting plate is flush with the bottom end of the second base plate, an elastic plate is provided above the connecting plate, the connecting plate and the elastic plate are an integrated structure, the angle between the connecting plate and the elastic plate is thirty to forty-five degrees, the whole formed by the connecting plate and the elastic plate is elastic, the end of the elastic plate close to the first base plate extends horizontally toward the lower end surface of the first base plate, the elastic plate is movably connected to the lower end surface of the first base plate, a threaded rod is threaded on the elastic plate, the center line direction of the threaded rod is perpendicular to the elastic plate, a spherical head is fixed to the bottom end of the threaded rod, the spherical head is in contact with the upper surface of the connecting plate, and a handle is fixed to the top end of the threaded rod.

[0029] Through the above implementation method, when the height of the first base plate needs to be adjusted, the staff manually turns the handle, and the rotation of the handle will drive the rotation of the threaded rod. Through the action of the thread, the threaded rod moves on the elastic plate, and the movement of the threaded rod will drive the movement of the spherical head. The movement of the spherical head on the upper surface of the connecting plate will drive the rotation of the elastic plate. The rotation of the elastic plate will drive the first base plate to move in the vertical direction. The height of the first base plate can be adjusted by the movement of the elastic plate to facilitate leveling of the spirit level.

[0030] As described above, the nickel-based alloy composite material for electrodes, preparation method and electrocatalytic electrode of the present invention include at least the following beneficial effects: when the inner cavity of the electrolytic cell body expands and contracts due to thermal expansion and contraction, the compensation component compensates for the spatial contraction and expansion caused by the thermal expansion and contraction, preventing the air pressure from exerting excessive force on the top cover, compensating for the connection between the electrolytic cell body and the top cover, reducing the possibility of the electrolytic cell body cavity impacting and damaging the connection between the electrolytic cell body and the top cover, thereby reducing the possibility of deformation and leakage at the connection, and improving the safety of the device.

DETAILED DESCRIPTION

[0037] The following describes the embodiments of the present invention through specific examples. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for the purpose of illustrating the present invention and are not intended to limit the scope of protection of the present invention.

[0038] like Figure 1-5 As shown, the present invention provides a technical solution: an electrolytic cell protection structure, comprising an electrolytic cell body 1 with an open top and a hollow interior, an ion diaphragm 2 fixed in the middle position of the electrolytic cell body 1, a top cover 11 for closing the opening position of the electrolytic cell body 1 is provided on the top of the electrolytic cell body 1, an electrode sheet structure 12 is fixed below the top cover 11, and the electrode sheet structure 12 extends into the electrolytic cell body 1, and a protective box body 6 is provided on the outside of the electrolytic cell body 1 to protect the electrolytic cell body 1, and the protective box body 6 is fixed to the top cover 11. The top cover 11 and the electrolytic cell body 1 are connected by a compensation component 3. The electrolytic cell body 1 is divided into a cathode chamber and an anode chamber by an ion diaphragm 2, and the electrode sheet structure 12 is composed of a cathode sheet and an anode sheet. The cathode sheet extends into the cathode chamber, and the anode sheet extends into the anode chamber. In addition, an air outlet pipe and a terminal connected to the top cover 11 are provided on the top cover 11. The top cover 11 is fixedly connected to the electrolytic cell body 1. The structure of the electrolytic cell body 1 and the connection between the electrolytic cell body 1 and the top cover 11 are all existing technologies, so they will not be described in detail here.

[0039] The electrolytic cell body 1 is placed inside the protective box body 6, which protects the electrolytic cell body 1 and reduces the impact of external dust, oil, etc. on the electrolytic cell body 1. The protective box body 6 is detachably fixed to the top cover 11, which does not affect the disassembly and assembly of the protective box body 6. At this time, the protective box body 6 and the top cover 11 form a closed structure. When the inner cavity of the electrolytic cell body 1 expands and contracts due to power outages, excessive operating temperature, or excessive operating temperature, the compensation component compensates for the contraction and expansion of the electrolytic cell body 1 caused by the thermal expansion and contraction, thereby compensating for the connection between the electrolytic cell body 1 and the top cover 11, reducing the impact damage caused by air pressure on the connection between the top cover 11 and the electrolytic cell body 1, and thereby reducing the possibility of deformation and leakage at the connection between the electrolytic cell body 1 and the top cover 11, thereby improving the safety of the device.

[0040] like Figure 1 and Figure 2 and Figure 3, a guide tube 303 is fixed to the lower end surface of the top cover 11, and the guide tube 303 extends vertically downward along the inner wall of the electrolytic cell body 1. A corrugated telescopic tube 304 is sleeved on the outer side of the guide tube 303. The top of the corrugated telescopic tube 304 is fixed to the lower end surface of the top cover 11, and the top of the guide tube 303 is fixedly connected to the top of the corrugated telescopic tube 304. A first annular mounting plate 301 is fixed to the outer periphery of the bottom end of the corrugated telescopic tube 304, and a second annular mounting plate 101 is fixed to the outer periphery of the top of the electrolytic cell body 1. The first annular mounting plate 301 and the second annular mounting plate 101 are fixedly connected by a number of locking bolts 302. Through the cooperation of the number of locking bolts 302, the first annular mounting plate 301 and the second annular mounting plate 101, the top cover 11, the corrugated telescopic tube 304 and the electrolytic cell body are 1 forms a sealing structure. The top cover 11 and the first annular mounting plate 301 are fixedly connected by the constraint component 4. When the electrolytic cell body 1 expands and contracts due to heat or cold, the first annular mounting plate 301 fixedly connected to the electrolytic cell body 1 will be driven to move. The movement of the first annular mounting plate 301 will drive the bellows 304 to expand and contract. The expansion and contraction of the bellows 304 compensates for the connection between the top cover 11 and the electrolytic cell body 1, compensating for the spatial contraction and expansion of the inner cavity of the electrolytic cell body 1 caused by thermal expansion and contraction, thereby reducing the possibility of leakage at the connection between the electrolytic cell body 1 and the top cover 11. The expansion and contraction of the bellows 304 can be adjusted by the constraint component 4. When the device is not in use, the bellows 304 needs to be temporarily constrained.

[0041] like Figure 1 and Figure 2 and Figure 3The constraint component 4 includes a third annular mounting plate 401 sleeved on the outer peripheral side wall of the top cover 11, and a first ear plate 402 is fixed at the four end corners of the outer periphery of the third annular mounting plate 401. A second ear plate 403 located directly below the first ear plate 402 is fixed at the four end corners of the outer periphery of the first annular mounting plate 301. Circular holes are opened on the first ear plate 402 and the second ear plate 403. The first ear plate 402 and the adjacent second ear plate 403 are penetrated by screws 404 through the circular holes. The top and bottom ends of the screws 404 pass through the first ear plate 402 and the second ear plate 403 respectively. The parts of the screws 404 that pass through the first ear plate 402 and the second ear plate 403 are threaded. A nut 405 is sleeved thereon, and the two nuts 405 respectively conflict with the first ear plate 402 and the second ear plate 403. When the bellows expansion tube 304 needs to be temporarily constrained, the screw 404 is passed through the first ear plate 402 and the second ear plate 403 from top to bottom. The two ends of the screw 404 pass through the first ear plate 402 and the second ear plate 403 respectively, and the parts of the screw 404 passing through the first ear plate 402 and the second ear plate 403 are both sleeved with nuts 405 through threads. The two nuts 405 respectively conflict with the first ear plate 402 and the second ear plate 403. Through the action of the nut 405 and the screw 404, the first ear plate 402 and the second ear plate 403 are fixedly connected.

[0042] When the device is formally used, the screw 404 and the nut 405 are removed from the first ear plate 402 and the second ear plate 403 without affecting the telescopic use of the second ear plate 403.

[0043] like Figure 2 and Figure 3 A guide assembly 5 is provided between the first ear plate 402 and the first annular mounting plate 301 to guide the second ear plate 403. There are two guide assemblies 5, and the two guide assemblies 5 are symmetrically arranged. Through the action of the guide assembly 5, when the bellows expansion tube 304 undergoes expansion and contraction deformation, the expansion and contraction deformation of the bellows expansion tube 304 is guided, so that the expansion and contraction deformation amounts of the left and right ends of the bellows expansion tube 304 are consistent, reducing the possibility that the electrode sheet structure 12 damages the inner wall of the electrolytic cell body 1 and the electrode sheet structure 12 is damaged due to the inconsistent expansion and contraction deformation amounts of the left and right ends of the bellows expansion tube 304.

[0044] like Figure 2 and Figure 3 and Figure 4The guide assembly 5 includes a positioning plate 509 fixedly connected to the outer periphery of the first annular mounting plate 301, a control box body 503 is fixed to the upper end surface of the positioning plate 509, an upper fixing plate 501 located just above the positioning plate 509 is fixedly connected to the outer periphery of the first ear plate 402, a lower fixing plate 506 located just below the positioning plate 509 is detachably fixed to the outer side wall of the electrolytic cell body 1, an axial sleeve 505 is fixed to the upper end surface of the lower fixing plate 506, and an axial guide column 502 is fixed to the lower end surface of the upper fixing plate 501. The column 502 passes through the control box body 503 and the positioning plate 509 from top to bottom, and the guide column 502 passes through the positioning plate 509 and extends into the sleeve 505. A rack 504 is fixed to the outer wall of the circumference of the guide column 502. The guide column 502 and the rack 504 are all slidably connected to the control box body 503, the positioning plate 509 and the sleeve 505. A gear 507 engaged with the rack 504 is rotatably connected in the control box body 503. A transmission shaft 508 is provided between two adjacent gears 507. The transmission shaft 508 Both ends of the bellows 304 are penetrated by adjacent control box bodies 503 and are rotatably connected to the control box bodies 503. The transmission shaft 508 penetrates the interior of the control box body 503 and is fixedly connected to the axis position of the gear 507. When one end of the bellows 304 produces telescopic deformation and the other end does not telescope synchronously, the telescopic end will drive one end of the top cover 11 to move. The movement of one end of the top cover 11 will drive the guide column 502 at that end to move in the vertical direction. The movement of the guide column 502 will drive the rack fixedly connected to the guide column 502. 504 moves, and the movement of the rack 504 will drive the gear 507 meshing with the rack 504 to rotate. The rotation of the gear 507 will drive the transmission shaft 508 fixedly connected to the gear 507 to rotate. The rotation of the transmission shaft 508 will drive another gear 507 fixedly connected to the transmission shaft 508 to rotate, thereby driving the adjacent racks 504 and guide columns 502 to move in the vertical direction, so that the left and right ends of the top cover 11 move at the same time, reducing the possibility of the electrode sheet structure 12 tilting due to the movement of one end of the top cover 11.

[0045] like Figure 3 The inner circumference of the protective box body 6 is fixed with an insulation sleeve 601 that reduces the thermal expansion and contraction of the electrolytic cell body 1. The four outer sides of the protective box body 6 are provided with anti-collision components 7. The insulation sleeve 601 has an insulation effect on the electrolytic cell body 1, reducing the possibility of thermal expansion and contraction of the electrolytic cell body 1, thereby reducing the possibility of deformation and penetration of the electrolytic cell body 1, improving the safety of the device, and reducing the damage caused by external impact to the electrolytic cell body 1 and the protective box body 6 through the action of the anti-collision component 7, thereby improving the service life and service life of the device, and facilitating the transportation of the electrolytic cell body 1 and the protective box body 6.

[0046] like Figure 2 and Figure 3The anti-collision component 7 includes a guide rail 701 fixedly connected to the outer periphery of the protective box body 6, and two first sliders 702 and two second sliders 703 are slidably connected to the guide rail 701.

An arc-shaped outer guard plate 705 is fixed between two adjacent first sliders 702, and an arc-shaped inner guard plate 704 is fixed between two adjacent second sliders 703. The arc-shaped inner guard plate 704 and the arc-shaped outer guard plate 705 are both convex toward the outside of the protective box body 6. The arc-shaped inner guard plate 704 and the arc-shaped outer guard plate 705 are convex toward the outside of the protective box body 6. The outer guard plates 705 are elastic. When the outside world collides with the arc-shaped inner guard plate 704 and the arc-shaped outer guard plate 705, the arc-shaped inner guard plate 704 and the arc-shaped outer guard plate 705 are deformed in turn, and respectively drive the second slider 703 fixedly connected to the arc-shaped inner guard plate 704 and the first slider 702 fixedly connected to the arc-shaped outer guard plate 705 to slide on the guide rail 701, thereby producing a buffering effect. In addition, the impacting object will also produce a reaction force under the action of the arc-shaped inner guard plate 704 and the arc-shaped outer guard plate 705, resulting in deceleration and turning, thereby reducing the damage to the protective box body 6.

[0047] like Figure 2 and Figure 3 , anti-slip plates 706 are fixed at both ends of the guide rail 701, and reinforcing ribs are fixed at the connection between the anti-slip plates 706 and the guide rail 701, and a rubber anti-collision block is fixed on the side of the anti-slip plate 706 close to the first slider 702. By arranging anti-slip plates 706 at both ends of the guide rail 701, the possibility of the first slider 702 and the second slider 703 falling off the guide rail 701 is reduced, and by arranging reinforcing ribs at the connection between the guide rail 701 and the anti-slip plate 706, the connection strength of the anti-slip plate 706 is improved, and the possibility of the first slider 702 colliding with the anti-slip plate 706 and causing damage to the anti-slip plate 706 is reduced by the action of the rubber anti-collision block.

[0048] like Figure 5, a first bottom plate 8 is fixed to the bottom end of the protective box body 6, a level 10 located next to the protective box body 6 is fixed on the upper surface of the first bottom plate 8, a second bottom plate 801 is provided directly below the first bottom plate 8, a rubber pad is fixed to the bottom end of the second bottom plate 801, the first bottom plate 8 and the second bottom plate 801 are fixedly connected by a leveling structure 9, through the action of the rubber pad, the electrolytic cell body 1 is transported and placed to reduce the impact of the electrolytic cell body 1, a plurality of axial guide columns are fixed at the middle position between the first bottom plate 8 and the second bottom plate 801, the guide columns include a sleeve column and an extension column, the bottom end of the sleeve column is fixedly connected to the upper surface of the second bottom plate 801, the extension column is slidably connected to the sleeve column, and one end of the extension column extending out of the sleeve column is connected to the first bottom plate The lower end surface of the plate 8 is fixedly connected, and the first bottom plate 8 is supported by the action of a number of guide columns, and the first bottom plate 8 and the second bottom plate 801 are conveniently fixedly connected, and a certain gap is formed between the first bottom plate 8 and the second bottom plate 801, which is convenient for a forklift to carry the protective box body 6 and the electrolytic cell body 1, and reduces the damage to the outer surface of the electrolytic cell body 1 by the lifting rope. When the second bottom plate 801 is placed on an uneven ground and operating table, it can be seen through the action of the spirit level 10 that the protective box body 6 and the electrolytic cell body 1 are not in a horizontal state. At this time, the protective box body 6 is leveled by the action of the leveling structure 9, reducing the possibility that the left and right electrolyzed water in the electrolytic cell body 1 will be unbalanced, resulting in a pressure difference on both sides of the ion diaphragm 2 and a decrease in gas purity.

[0049] like Figure 5The leveling structure 9 includes a horizontally arranged connecting plate 901, which is fixedly connected to the second bottom plate 801, and the bottom end of the connecting plate 901 is flush with the bottom end of the second bottom plate 801. An elastic plate 905 is provided above the connecting plate 901. The connecting plate 901 and the elastic plate 905 are an integrated structure. The angle between the connecting plate 901 and the elastic plate 905 is thirty to forty-five degrees. The whole formed by the connecting plate 901 and the elastic plate 905 is elastic. The end of the elastic plate 905 close to the first bottom plate 8 extends horizontally toward the lower end surface of the first bottom plate 8. The elastic plate 905 is movably connected to the lower end surface of the first bottom plate 8. A threaded rod 902 is threaded through the elastic plate 905, and the center line direction of the threaded rod 902 is perpendicular to the elastic plate 905. A spherical head 903 is fixed to the bottom end of the threaded rod 902, and the spherical head 903 is in contact with the upper surface of the connecting plate 901. A handle 904 is fixed to the top of the threaded rod 902. When the height of the first base plate 8 needs to be adjusted, the staff manually turns the handle 904. The rotation of the handle 904 will drive the rotation of the threaded rod 902. Through the action of the thread, the threaded rod 902 moves on the elastic plate 905. The movement of the threaded rod 902 will drive the movement of the spherical head 903. The movement of the spherical head 903 on the upper surface of the connecting plate 901 will drive the rotation of the elastic plate 905. The rotation of the elastic plate 905 will drive the first base plate 8 to move in the vertical direction. The height of the first base plate 8 can be adjusted by moving the elastic plate 905 to facilitate the leveling of the spirit level 10.

[0050] During use, the first annular mounting plate 301 and the second annular mounting plate 101 are fixedly connected by a plurality of locking bolts 302. A rubber sealing strip is provided at the connection between the first annular mounting plate 301 and the second annular mounting plate 101 to improve sealing. At this time, the top cover 11 and the bellows expansion tube 304 seal the electrolytic cell body 1. The nut 405 is removed by threading, so that the screw 404 is disconnected from the first ear plate 402 and the second ear plate 403.

[0051] The staff placed the electrolytic cell body 1 in the protective box body 6. The bottom of the electrolytic cell body 1 was completely fitted with the bottom of the protective box body 6. The protective box body 6 reduced the impact of dust, oil, etc. on the electrolytic cell body 1.

[0052] The thermal insulation sleeve 601 is used to insulate the electrolytic cell body 1, thereby reducing the possibility of thermal expansion and contraction of the internal cavity of the electrolytic cell body 1. The thermal insulation sleeve 601 is elastic. When the internal cavity of the electrolytic cell body 1 expands and contracts, causing the space to shrink and expand, the thermal insulation sleeve 601 reduces the possibility of the internal cavity air pressure impacting the electrolytic cell body 1 and causing deformation of the electrolytic cell body 1, thereby reducing the possibility of deformation of the protective box body 6, thereby increasing the service life of the protective box body 6.

[0053] Then, the protective box body 6 is fixedly connected to the top cover 11;

[0054] Observe the spirit level 10 to determine whether the protective box body 6 is in a horizontal state. When the protective box body 6 is not in a horizontal state, grasp the handle 904 and manually rotate the handle 904. The rotation of the handle 904 will drive the rotation of the threaded rod 902, and the rotation of the threaded rod 902 will drive the rotation of the elastic plate 905. The rotation of the elastic plate 905 controls the movement of the first bottom plate 8 in the vertical direction. The guide pillar guides the movement of the first bottom plate 8 until the protective box body 6 is in a horizontal state, thereby reducing the possibility that the electrolysis of water in the electrolytic cell body 1 is unbalanced due to the protective box body 6 not being in a horizontal state, resulting in a pressure difference on both sides of the ion diaphragm 2 and a decrease in gas purity.

[0055] At the same time, through the gap between the first bottom plate 8 and the second bottom plate 801, when it is necessary to transport the protective box body 6 and the electrolytic cell body 1, a forklift can use the gap between the first bottom plate 8 and the second bottom plate 801 to transport the electrolytic cell body 1, thereby reducing the damage to the outer wall of the electrolytic cell body 1 and the protective box body 6 caused by the lifting rope;

[0056] When the power is turned on and the switch is turned on, when the electrode sheet structure 12 and the electrolytic cell body 1 are in operation, if the operating temperature is too high, too low, or there is a power outage, causing the inner cavity of the electrolytic cell body 1 to expand and contract due to heat, the bellows 304 compensates for the contraction and expansion of the space caused by the thermal expansion and contraction. The contraction and expansion of the inner cavity of the electrolytic cell body 1 will cause the bellows 304 to deform, and the flow guide tube 303 slides within the bellows 304. The bellows 304 reduces the impact of the air pressure in the electrolytic cell body 1 on the connection between the top cover 11 and the electrolytic cell body 1, thereby reducing the possibility of leakage at the connection and improving the safety of the device.

[0057] At the same time, when one end of the bellows expansion tube 304 is deformed, the top cover 11 at the deformed end of the bellows expansion tube 304 is tilted, and the movement of the top cover 11 will drive the guide column 502 fixedly connected to the top cover 11 to move in the vertical direction. The movement of the guide column 502 will drive the movement of the rack 504 fixedly connected to the guide column 502. The movement of the rack 504 will drive the rotation of the gear 507 meshing with the rack 504. The rotation of the gear 507 will drive the rotation of the transmission shaft 508 fixedly connected to the gear 507. The rotation of the transmission shaft 508 will drive the gear 507 at the other end to rotate, thereby facilitating the balance of the left and right ends of the top cover 11, reducing the possibility of the electrode sheet structure 12 being damaged by contact with the inner wall of the electrolytic cell body 1 due to the imbalance of the left and right ends of the top cover 11;

[0058] One end of the transmission shaft 508 is close to the cathode chamber, and the other end is close to the anode chamber;

[0059] When the outside world collides with the arc-shaped inner guard plate 704 and the arc-shaped outer guard plate 705, the arc-shaped inner guard plate 704 and the arc-shaped outer guard plate 705 are deformed in turn, and respectively drive the second slider 703 fixedly connected to the arc-shaped inner guard plate 704 and the first slider 702 fixedly connected to the arc-shaped outer guard plate 705 to slide on the guide rail 701, thereby producing a buffering effect. The impacting object will also produce a reaction force under the action of the arc-shaped inner guard plate 704 and the arc-shaped outer guard plate 705, resulting in deceleration and turning, thereby reducing the damage to the protective box body 6 and increasing the service life of the protective box body 6. This is the use process of the electrolytic cell protection structure. At the same time, the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
