Description

Technical Field

[0001] The invention relates to the technical field of hydrogen production by electrolysis, and in particular to a device for producing hydrogen by electrolyzing water. Background Art

[0002] Hydrogen production by water electrolysis is a method of producing hydrogen by electrolyzing water. This method is based on electrochemical principles and has the advantages of being environmentally friendly, low-cost, high-efficiency, and renewable. In a water electrolysis hydrogen production device, in order to prevent the mixing of hydrogen and oxygen on both sides, a diaphragm needs to be set between the cathode pool and the anode pool. However, the service life of the diaphragm is limited. Once the diaphragm ages, the gases on both sides will mix. The replacement of the diaphragm of traditional water electrolysis equipment is extremely cumbersome, which will greatly affect the working efficiency of the water electrolysis equipment.

[0003] To this end, Chinese patent CN113737219B discloses a device for preventing mixing of hydrogen produced by electrolysis, which facilitates the replacement of the diaphragm by pulling out the mounting plate from the corresponding mounting groove. When the mounting plate is pulled out, the travel switch is closed and the corresponding negative electrode plate is powered off, causing the corresponding electromagnetic butterfly valve to close, cutting off the connection between the positive electrode pool and the corresponding negative electrode pool, thereby cutting off the hydrogen production reaction between the two. However, the other negative electrode pool can still react with the positive electrode pool to produce hydrogen, so that when replacing the corresponding diaphragm, the diaphragm can be replaced without shutting down the hydrogen generator, making the replacement of the diaphragm more convenient and quick, effectively preventing the mixing of gases on both sides caused by aging of the diaphragm, and increasing the safety during hydrogen production.

[0004] However, although the traditional water electrolysis equipment can continue to work through the secondary diaphragm when replacing the diaphragm, the water electrolysis equipment still needs to stop running during the process of moving the diaphragm, and the working efficiency of the secondary diaphragm is limited. Therefore, the replacement of the diaphragm will still affect the operation of the water electrolysis equipment. Summary of the invention

DETAILED DESCRIPTION

[0030] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] Reference Figure 1-Figure 3 A device for producing hydrogen by electrolyzing water comprises an electrolytic box 1 provided with a negative electrode pool and a positive electrode pool, a bracket 11 is provided in the electrolytic box 1, the bracket 11 is located between the negative electrode pool and the positive electrode pool, a mounting frame 2 and a propulsion device 3 are provided on the bracket 11, at least three mounting frames 2 are provided, at least two working positions are provided on the bracket 11, and a storage position for accommodating the mounting frames 2 is also provided on the bracket 11, wherein two mounting frames 2 are respectively located at two working positions, and the remaining mounting frames 2 are located at the storage positions, and the two sides of the mounting frames 2 located at the working positions are respectively connected to the negative electrode pool and the positive electrode pool, and the propulsion device 3 is used to control the mounting frames 2 to move toward the working positions.

[0032] The present invention realizes the function of alternately working through multiple diaphragms 21 when disassembling and assembling the diaphragm 21 through the electrolytic box 1, the mounting frame 2 and the propulsion device 3, thereby reducing the effect of disassembling and assembling the diaphragm 21 on the water electrolysis efficiency, and the propulsion device 3 achieves the effect of quickly using the spare diaphragm 21 with the diaphragm 21 removed when disassembling the mounting frame 2, thereby solving the problem that the operation efficiency of the equipment will be greatly affected during the disassembly and maintenance of the diaphragm 21 in traditional equipment. A gas storage tank 14 is respectively provided on both sides of the electrolytic box 1, and the two gas storage tanks 14 are respectively connected to the negative electrode pool and the positive electrode pool through the connecting pipe 13, and the negative electrode pool and the positive electrode pool are respectively provided with a negative electrode plate and a positive electrode plate, and two negative electrode pools are provided in the electrolytic box 1; by installing the diaphragm 21 on the mounting frame 2, the effect of quickly disassembling and assembling the diaphragm 21 is achieved. When performing maintenance and inspection of the diaphragm 21, the mounting frame 2 located at the working position is first removed from the bracket 11, and then the spare mounting frame 2 and diaphragm 21 located at the storage position are driven toward the working position by the propulsion device 3, and then the spare diaphragm 21 is used to replace the diaphragm 21 at the working position, so as to achieve the effect of quickly replacing the new diaphragm 21 for work after the diaphragm 21 is removed, thereby ensuring the working efficiency of the electrolysis of water to the greatest extent, and there are at least two working positions on the bracket 11. Therefore, even if the diaphragm 21 at one of the working positions cannot work during the disassembly and assembly process, the diaphragm 21 at the other working position can ensure the normal operation of the electrolysis process, and store hydrogen and oxygen respectively through two gas tanks 14.

[0033] Reference Figure 3-Figure 5 The propulsion device 3 includes a first elastic member 31 and a pushing assembly 32, the first elastic member 31 is installed on the bracket 11, and one end of the first elastic member 31 is connected to the mounting frame 2 in the storage position, and the first elastic member 31 is in a vertical state, a cover plate 12 for limiting the moving direction of the mounting frame 2 is slidably installed on the electrolytic box 1, and both ends of the mounting frame 2 are provided with a pushing assembly 32 for pushing the mounting frame 2, in the working state, the pushing assemblies 32 of adjacent mounting frames 2 abut against each other, when the mounting frame 2 in the working position is removed, the mounting frame 2 in the storage position adjacent to the mounting frame 2 moves toward the working position under the pushing action of the pushing assembly 32, and moves to the working position under the elastic force of the first elastic member 31.

[0034] The present invention realizes the function of automatically driving the mounting frame 2 located at the storage position to move toward the working position through the first elastic member 31, the push assembly 32 and the cover plate 12. The bracket 11 is provided with a first hinge seat 311, one end of the first elastic member 31 is hinged to the first hinge seat 311, and the other end of the first elastic member 31 is hinged to the second hinge seat 312, and the second hinge seat 312 is connected to the mounting frame 2. When the mounting frame 2 located at the storage position is in the reset state, the pushing assemblies 32 on both sides of the mounting frame 2 are respectively abutted against the pushing assemblies 32 on the mounting machines located at the two working positions, and then the first elastic member 31 is preferably a nitrogen spring. When disassembling the mounting frame 2, the operator first slides the cover plate 12 to make way for the position where the mounting frame 2 needs to be disassembled, and then disassembles the mounting frame 2, and then removes the diaphragm 21 located on the mounting frame 2. At the same time, the pushing assembly 32 on the side of the mounting frame 2 located at the storage position close to the disassembled mounting frame 2 loses its abutting force, and the pushing assembly 32 on the other side pushes the mounting frame 2 toward the working position, thereby destroying the force balance of the mounting frame 2, causing the first elastic member 31 to tilt and the first elastic member 31 to stretch, thereby pushing the mounting frame 2 toward the working position, replacing the original mounting frame 2 and diaphragm 21 to work.

[0035] Reference Figure 5 and Figure 6 The pushing assembly 32 includes a pushing block 321 and a second elastic member 322. The pushing block 321 is slidably mounted on the mounting frame 2. Both ends of the second elastic member 322 are connected to the pushing block 321 and the mounting frame 2 respectively.

[0036] The present invention realizes the function of pushing the mounting frame 2 located at the storage position to deviate after the mounting frame 2 is disassembled by means of the push block 321 and the second elastic member 322, so as to achieve the effect of destroying the force balance of the mounting frame 2, so that the first elastic member 31 can stably drive the mounting frame 2 to move. After the mounting frame 2 is disassembled, the push assembly 32 on the side of the mounting frame 2 located at the storage position close to the disassembled mounting frame 2 loses the pressing force, and the push block 321 on the other side thereof pushes the mounting frame 2 to move toward the working position under the elastic force of the second elastic member 322, thereby destroying the force balance of the mounting frame 2, causing the first elastic member 31 to tilt, and the first elastic member 31 to extend, thereby pushing the mounting frame 2 to move toward the working position, replacing the original mounting frame 2 and the diaphragm 21 to work.

[0037] Reference Figure 4 A rotating frame 4 is rotatably arranged on the bracket 11, a diaphragm 21 is arranged on the rotating frame 4, and a rotating driver 41 for controlling the rotation of the rotating frame 4 is also arranged on the bracket 11.

[0038] The present invention realizes the function of further increasing the spare diaphragm 21 through the rotating frame 4 and the rotating driver 41. In order to improve the utilization rate of the diaphragm 21, the area of ​​the bracket 11 should not be too large, so only one spare mounting frame 2 and diaphragm 21 are provided on the bracket 11. When the diaphragm 21 and the mounting frame 2 on one side are removed, one of the spare mounting frames 2 replaces the mounting frame 2 and the diaphragm 21 to work under the drive of the propulsion device 3. When both mounting frames 2 at the working position are removed, only one spare diaphragm 21 is not enough to use. For this reason, a rotating frame 4 is designed, and the rotating frame 4 is driven to rotate by the rotating driver 41 to rotate the diaphragm 21 on the rotating frame 4 to the working position, so as to achieve the effect of replacing the diaphragm 21 at the original working position. In order to ensure the sealing of the rotating frame 4, a soft rubber sleeve for improving the sealing is provided in the second accommodating chamber 113 for rotating the rotating frame 4. The soft rubber sleeve is not shown in the figure, and the soft rubber sleeve is only one of the preferred ways to improve the sealing. Only when the rotating frame 4 rotates to the working position, the rotating frame 4 and the bracket 11 are tightly fitted, and when the diaphragm 21 on the rotating frame 4 is not in the working position, the sealing of the electrolytic box 1 is ensured by the soft rubber sleeve.

[0039] Reference Figure 4 and Figure 7 A mounting plate 42 is detachably provided on the rotating frame 4 , and the diaphragm 21 located on the rotating frame 4 is arranged on the mounting plate 42 .

[0040] The present invention realizes the function of quickly disassembling and assembling the diaphragm 21 on the rotating frame 4 through the mounting plate 42. The rotating frame 4 can move between two working positions under the drive of the rotating driver 41, and when the rotating frame 4 is in a horizontal state, the diaphragm 21 on the rotating frame 4 is located at the working position. When the rotating frame 4 is in a vertical state, the diaphragm 21 on the rotating frame 4 is located outside the electrolytic box 1. The diaphragm 21 on the rotating frame 4 can be replaced or maintained by removing the mounting plate 42 on the rotating frame 4, thereby improving the maintenance portability of the diaphragm 21 on the rotating frame 4. Since a spare mounting frame 2 and a diaphragm 21 are originally provided on the bracket 11, the diaphragm 21 on the rotating frame 4 is only temporarily reserved. When the diaphragm 21 on the rotating frame 4 is used, since the mounting frame 2 on the working position is more portable, the diaphragm 21 on the rotating frame 4 is replaced by the diaphragm 21 on the working position, thereby reducing the utilization rate of the diaphragm 21 on the rotating frame 4, so that when the spare diaphragm 21 is insufficient, the diaphragm 21 on the rotating frame 4 can be used for emergency use.

[0041] Reference Figure 4 and Figure 7 : A buckle groove 421 for grasping is provided on both sides of the mounting plate 42.

[0042] The buckle grooves 421 of the present invention realize the function of facilitating the operator to disassemble and assemble the mounting plate 42. Since the outer arc surface of the mounting plate 42 is flush with the arc surface of the rotating frame 4, there is no good gripping point when disassembling the mounting plate 42. Therefore, by providing the buckle grooves 421 on both sides of the mounting plate 42, it is convenient for the operator to disassemble the mounting plate 42 from the rotating frame 4, thereby improving the portability of disassembly and assembly of the mounting plate 42 on the rotating frame 4.

[0043] Reference Figure 3 and Figure 5 A transverse plate 22 is disposed at the top of the mounting frame 2, and the transverse plate 22 is slidably matched with the bracket 11, and a first handle 221 for grasping is disposed on the transverse plate 22.

[0044] The present invention realizes the function of facilitating the operator to move the mounting frame 2 through the transverse plate 22 and the first handle 221. The bracket 11 is provided with a first storage compartment and a second storage compartment, and the first storage compartment is also provided with a guide rail 112 for guiding the movement of the transverse plate 22. The mounting frame 2 located at the storage position and the working position is both in the first storage compartment, the rotating frame 4 is located in the second storage compartment, and the second storage compartment is provided with a storage groove for the first elastic member 31 to rotate. When maintaining the diaphragm 21, it is necessary to move the diaphragm 21 by disassembling the mounting frame 2. For this purpose, the transverse plate 22 and the first handle 221 are provided on the mounting frame 2, and the sliding of the mounting frame 2 is guided by the sliding cooperation between the transverse plate 22 and the bracket 11, and the first handle 221 is a long handle for easy gripping, which further improves the disassembly efficiency and portability of the diaphragm 21.

[0045] Reference Figure 4 and Fig. 9 A sliding cover 121 is slidably mounted on the cover plate 12, and a second handle 122 is mounted on the sliding cover 121.

[0046] The present invention realizes the function of facilitating the operator to open and close the cover plate 12 through the sliding cover 121 and the second handle 122. When disassembling the mounting frame 2, the operator slides the sliding cover 121 by gripping the second handle 122, thereby avoiding the gap for the mounting frame 2 to pass through. When disassembling the mounting frame 2, the operator only needs to slide the sliding cover 121 toward the corresponding side by the width of one mounting frame 2, thereby ensuring the stable fixation of the remaining mounting frames 2, and can also quickly reset the mounting frame 2 after disassembling it. A magnet is provided on the second hinge seat 312, and a docking groove docking with the second hinge seat 312 is provided on the mounting frame 2. When the magnet cooperates with the docking groove, it cooperates with the mounting frame 2 by magnetic attraction. When disassembling the hinge seat located in the storage position, the operator slides the slide cover 121. When the mounting frame 2 loses the abutment effect of the slide cover 121, the first elastic member 31 extends and the mounting frame 2 is removed at the same time. The portability of disassembly is improved by the elastic force of the first elastic member 31, and the second hinge seat 312 is removed from the mounting frame 2 during the disassembly process. During installation, it is necessary to overcome the elastic force of the first elastic member 31 and fix the mounting frame 2 to the bracket 11 through the slide cover 121.

[0047] Reference Figure 6 : An oblique guide block 3211 is provided at the bottom of the push block 321, and the oblique guide block 3211 is slidably matched with the mounting frame 2.

[0048] The present invention realizes the function of guiding the push block 321 to slide by the inclined guide block 3211, so as to facilitate the operator to install the mounting frame 2 on the bracket 11. When the mounting frame 2 is installed on the bracket 11, it is necessary to compress the push assembly 32 so that the push assembly 32 on the adjacent mounting frame 2 is tightly matched. For this purpose, an inclined guide block 3211 is provided on the push block 321. When the mounting frame 2 is pushed onto the bracket 11, the mounting frame 2 pushed to the working position by the propulsion device 3 is first pushed to the storage position, and then the mounting frame 2 is pushed down. During the pushing process, the inclined guide block 3211 below the push block 321 contacts the push block 321 on the adjacent mounting frame 2, and then the push block 321 is guided to move by the inclined surface of the inclined guide block 3211, and the second elastic member 322 is compressed so that the push blocks 321 on the adjacent mounting frames 2 are abutted against each other.

[0049] Reference Fig. 9 and Fig.10: A mounting seat 5 is slidably installed on the bracket 11, and a guide tube 51 is provided on the mounting seat 5. A tapered opening 511 is provided on the side of the guide tube 51 close to the mounting frame 2. A guide rod 52 is provided on the mounting seat 5, and a third elastic member 521 is sleeved on the guide rod 52. The two ends of the third elastic member 521 are respectively connected to the mounting seat 5 and the bracket 11; in the working state, when the mounting frame 2 is disassembled, the mounting seat 5 moves toward the bracket 11 under the elastic force of the third elastic member 521, and when the propulsion device 3 drives the mounting frame 2 located in the storage position to move toward the working position, the tapered opening 511 of the guide tube 51 will be squeezed to move the guide tube 51 away from the mounting frame 2.

[0050] The present invention achieves the function of preventing the gases on both sides from mixing from the gap of the bracket 11 through the mounting seat 5, the guide tube 51, the tapered mouth 511, the guide rod 52 and the third elastic member 521. When the mounting frames 2 at the two working positions are removed, they need to be temporarily used through the diaphragm 21 on the rotating frame 4, and the rotating frame 4 is located in the second accommodating chamber 113. There is a gap between the second accommodating chamber 113 and the first accommodating chamber 111, which results in a gap at the mounting frame 2 on the working position of the bracket 11. In order to prevent the gases on both sides from leaking and mixing from the gap, the guide tube 51 is provided for sealing and guiding.

[0051] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
