Description

Technical Field

[0001] This utility model relates to a high-voltage electrolytic hydrogen production electrolyzer assembly, specifically a high-voltage electrolytic hydrogen production electrolyzer assembly that is easy to disassemble and assemble. Background Technology

[0002] High-pressure electrolysis hydrogen production electrolyzer is a device used to efficiently produce hydrogen. It decomposes water molecules into hydrogen and oxygen under high pressure by electrolyzing water.

[0003] Chinese patent discloses a high-voltage electrolytic hydrogen production electrolyzer assembly that is easy to disassemble and assemble (authorization announcement number CN220034679 U). This patented technology allows for the removal and replacement of only the damaged parts when the ion exchange membrane or electrode rods are damaged, eliminating the need to replace the entire electrolyzer assembly and thus reducing electrolysis costs. This patented technology, through a pump and injection pipe, enables more efficient and precise injection of electrolyte into the electrolyzer, avoiding uneven injection that could affect the electrolysis process. However, this patented technology still lacks convenience in the disassembly and assembly of the electrode rods and the opening and closing of the sealing cap. Therefore, those skilled in the art have provided a high-voltage electrolytic hydrogen production electrolyzer assembly that is easy to disassemble and assemble to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a high-voltage electrolytic hydrogen production electrolyzer assembly that is easy to assemble and disassemble, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-voltage electrolytic hydrogen production electrolyzer assembly that is easy to assemble and disassemble includes an electrolyzer, a tank cover, electrode rods, snap-fit ​​devices, hinges, spring clips, and an ion-exchange membrane. A hinge is installed at one end of the electrolyzer and the tank cover, and a spring clip is installed at the other end of the electrolyzer and the tank cover. The spring clip includes a rocker arm, a slot plate, and a slot plate mounting bracket. The tank cover is installed above the electrolyzer, and two electrode rods are installed on the tank cover. Each electrode rod has three snap-fit ​​devices installed on it, and the snap-fit ​​devices are also installed on the tank cover. Two liquid injection holes are symmetrically arranged at the bottom of the electrolyzer, and a water pump is installed below the liquid injection holes and mounted on a base plate. Four identical mounting posts are arranged at the bottom of the electrolyzer and mounted on the base plate. An ion-exchange membrane mounting slot is provided in the middle of the electrolyzer, and an ion-exchange membrane is installed in the ion-exchange membrane mounting slot.

[0007] As a further embodiment of this utility model: a rocker arm is installed at one end of the slot cover, and the other end of the rocker arm is installed in the slot plate. The slot plate is provided with a groove of a special structure and the bottom of the groove is W-shaped. The slot plate is slidably connected to the slot plate mounting bracket. Two identical springs are installed at the top of the slot plate and the other end of the springs is installed on the slot plate mounting bracket. Two identical locking blocks are provided at both ends of the inner wall of the slot plate mounting bracket and the locking blocks are located above the slot plate. The slot plate mounting bracket is installed on the top side of the electrolytic cell.

[0008] As a further embodiment of this utility model: the lower part of both the outer shell and the inner shell is a conical structure, the conical structure of the inner shell is provided with four grooves and a ball is provided in the groove, and the spring abutment is provided at the top of the ball.

[0009] As a further embodiment of this utility model: the buckling device includes an outer shell, an inner shell, a first spring, a telescopic rod, a fixing pin, a spring stop plate, and a ball. The outer shell is installed in the buckling groove, and the inner shell is provided inside the outer shell. The first spring and the telescopic rod are installed on the top of the inner wall of the outer shell, and the spring stop plate is installed on the other end of the first spring and the telescopic rod.

[0010] As a further improvement of this utility model: the top of the slot cover has several magnetic thin plates, and a snap-fit ​​slot and a rod slot are provided directly below the magnetic thin plates. The three snap-fit ​​slots are arranged circumferentially and equidistantly on the outside of the rod slot. The slot cover is provided with a total of two rod slots and six snap-fit ​​slots. An electrode rod is installed below each rod slot, and a snap-fit ​​device is installed in each snap-fit ​​slot. A chuck is installed on the snap-fit ​​device, and the chuck is fixedly connected to the electrode rod.

[0011] As a further embodiment of this utility model: the bottom disc-shaped structure of the fixing pin is installed at the lower end of the chuck, and the diameter of the disc structure of the fixing pin is larger than the diameter of the through hole on the chuck, and the chuck is provided with three through holes.

[0012] As a further embodiment of this utility model: the spring stop plate also has a frustum structure. The lower end of the frustum structure of the inner shell, the inner shell, and the spring stop plate is provided with a through hole and a fixing pin is installed in the through hole. The upper diameter of the fixing pin gradually increases downward and the middle diameter is smaller and the bottom diameter is larger, forming a disc shape.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The spring buckle used in this utility model can quickly lock and open the electrolytic cell and the cell cover. The cell cover can be flipped over by a hinge. When the cell cover and the electrolytic cell are closed, the rocker arm at one end of the cell cover can slide into the irregular groove on the slot plate and finally embed into the middle of the W-shaped structure at the bottom of the groove. Thus, the upward movement of the rocker arm is restricted. At this time, the upward movement of the slot plate will be blocked by the locking block. At this time, the electrolytic cell and the cell cover cannot be opened directly. By pulling the slot plate upward and then downward, the electrolytic cell and the cell cover can be unlocked.

[0015] 2. The snap-fit ​​device used in this utility model allows the electrode rod to be securely and quickly installed on the slot cover and facilitates quick assembly and disassembly. The snap-fit ​​device locks the chuck on the electrode rod between the disc structure at the bottom of the fixing pin and the outer shell. When installing the electrode rod, first insert the electrode rod into the rod slot. At this time, the chuck is located below the outer shell, and the chuck and the outer shell have not yet been inserted into the fixing pin. When the fixing pin is inserted, because the diameter of the first part of the fixing pin increases, the fixing pin can push the ball outward. Due to the outward push of the ball, the inner shell slides on the outer shell and slides upward. When the fixing pin is inserted into the middle part, because the diameter of the middle part is smaller, the ball moves inward under the action of the spring, and the outer shell moves downward. At this time, if the fixing pin is to be pulled out, it will not be successful because the ball is pressed by the spring plate. The snap-fit ​​device fixes the electrode rod on the slot cover. To unlock, a strong magnet of the corresponding shape of the magnetic thin plate needs to be placed at the magnetic thin plate so that the spring plate is attracted and moved upward, thereby unlocking. The locking process of the snap-fit ​​device only requires the insertion of the fixing pin, which is very convenient. Attached Figure Description

An ion membrane mounting tank 105 is arranged in the middle of the electrolytic cell 1, and an ion membrane 7 is installed in the ion membrane mounting tank 105.

[0025] The top of the slot cover 2 has several magnetic thin plates 201. Directly below the magnetic thin plates 201, there are snap-fit ​​slots 203 and rod slots 202. The three snap-fit ​​slots 203 are arranged circumferentially and equidistantly on the outside of the rod slots 202. The slot cover 2 has a total of two rod slots 202 and six snap-fit ​​slots 203. An electrode rod 3 is installed below each rod slot 202. A snap-fit ​​device 4 is installed in each snap-fit ​​slot 203. A chuck 301 is installed on the snap-fit ​​device 4. The chuck 301 is fixedly connected to the electrode rod 3.

[0026] The buckling device 4 includes an outer shell 401, an inner shell 402, a spring 403, a telescopic rod 404, a fixing pin 405, a spring stop plate 406, and a ball 407. The outer shell 401 is installed in the buckling groove 203. The inner shell 402 is provided inside the outer shell 401. The spring 403 and the telescopic rod 404 are installed on the top of the inner wall of the outer shell 401. The spring stop plate 406 is installed on the other end of the spring 403 and the telescopic rod 404.

[0027] The lower parts of both the outer shell 401 and the inner shell 402 are tapered. The tapered structure of the inner shell 402 is provided with four grooves and a ball 407 is provided in each groove. The spring abutment 406 is provided at the top of the ball 407.

[0028] The spring stop plate 406 also has a frustum structure. The inner shell 402, the inner shell 402, and the spring stop plate 406 all have through holes at the lower end of their frustum structures, and a fixing pin 405 is installed in the through hole. The upper diameter of the fixing pin 405 gradually increases downward, and the middle diameter is smaller while the bottom diameter is larger, forming a disc shape.

[0029] The bottom disc-shaped structure of the fixing pin 405 is installed at the lower end of the chuck 301, and the diameter of the disc structure of the fixing pin 405 is larger than the diameter of the through hole on the chuck 301. The chuck 301 is provided with three through holes.

[0030] A rocker arm 601 is installed at one end of the slot cover 2, and the other end of the rocker arm 601 is installed in the slot plate 602. The slot plate 602 has a groove with a special structure and the bottom of the groove is W-shaped. The slot plate 602 is slidably connected to the slot plate mounting bracket 603. Two identical springs 604 are installed at the top of the slot plate 602, and the other end of the springs 604 is installed on the slot plate mounting bracket 603. Two identical locking blocks 605 are provided at both ends of the inner wall of the slot plate mounting bracket 603, and the locking blocks 605 are located above the slot plate 602. The slot plate mounting bracket 603 is installed on the top side of the electrolytic cell 1.

[0031] Working principle of this utility model:

[0032] The spring buckle 6 can quickly lock and open the electrolytic cell 1 and the cell cover 2. The cell cover 2 can be flipped by the hinge 5. When the cell cover 2 and the electrolytic cell 1 are closed, the rocker 601 at one end of the cell cover 2 can slide into the irregular groove on the slot plate 602 and finally embed into the middle of the W-shaped structure at the bottom of the groove. Thus, the upward movement of the rocker 601 is restricted. At this time, the upward movement of the slot plate 602 will be blocked by the locking block 605. At this time, the electrolytic cell 1 and the cell cover 2 cannot be opened directly. By pulling the slot plate 602 upward and then downward, the electrolytic cell 1 and the cell cover 2 can be unlocked.

[0033] The latching device 4 allows the electrode rod 3 to be securely and quickly installed on the slot cover 2 and facilitates quick assembly and disassembly. The latching device 4 locks the chuck 301 on the electrode rod 3 between the disc structure at the bottom of the fixing pin 405 and the outer shell 401. When installing the electrode rod 3, first insert the electrode rod 3 into the rod slot 202. At this time, the chuck 301 is located below the outer shell 401, and the chuck 301 and the outer shell 401 have not yet been inserted into the fixing pin 405. When the fixing pin 405 is inserted, because the diameter of the initial section of the fixing pin 405 increases, the fixing pin 405 can push the ball 407 outwards. This outward push of the ball 407 causes the inner shell 402 to... The outer shell 401 slides and the inner shell 402 slides upward. When the fixing pin 405 is inserted into the middle section, the ball 407 moves inward under the action of the spring due to the smaller diameter of the middle section, while the outer shell 401 moves downward. At this time, if the fixing pin 405 is to be pulled out, it will not be successful because the ball 407 is pressed by the spring abutment 406. The latching device 4 fixes the electrode rod 3 on the slot cover 2. To unlock, a strong magnet of the corresponding shape of the magnetic thin plate 201 needs to be placed at the magnetic thin plate 201 so that the spring abutment 406 is attracted and moved upward, thereby unlocking. The locking process of the latching device 4 only requires the insertion of the fixing pin 405, which is very convenient.

[0034] The structure of the injection hole 101 and the water pump 102 is for pumping in electrolyte, and the ion membrane 7 can be quickly pulled out of the ion membrane mounting slot 105 for easy disassembly and assembly.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
