Description

Technical Field

[0001] This utility model relates to the field of water electrolysis processing technology, specifically to a water electrolysis hydrogen production device. Background Technology

[0002] Electrolysis of water to produce hydrogen is a process that uses electricity to decompose water into hydrogen and oxygen. Its basic principle is to use two electrodes in an electrolytic cell, the cathode and the anode, to pass an electric current through the water, causing reduction and oxidation reactions. This reduces hydrogen ions in the water molecules to hydrogen gas, while oxidizing oxygen ions to oxygen gas. Generally, adding an electrolyte (such as sodium hydroxide or potassium hydroxide) can increase the degree of water ionization, thereby accelerating hydrogen production.

[0003] According to a public disclosure (Publication No.: CN218710896U) of a water electrolysis hydrogen production device, a housing is included. A warning component for water level alerts is located on the right side of the housing. The warning component includes a mounting rod on the right side of the housing, with an infrared transmitter and an infrared receiver mounted on the rod. In this invention, by adding the warning component, workers no longer need to monitor the water level constantly, avoiding the need for real-time monitoring to prevent the water level from reaching its limit. This improves worker efficiency and solves the problem of workers being unable to perform other tasks due to the need for constant monitoring. In the aforementioned application, the infrared transmitter and receiver within the warning component work together to trigger an alarm when the water level reaches its limit. However, the timing of the infrared transmitter's signal being transmitted to the infrared receiver during the reflector's movement is not fixed, resulting in a limited timing for the infrared receiver and thus unstable alarm timing, affecting the alarm effect and requiring further improvement. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an electrolytic water hydrogen production device, solving the problems mentioned in the background section. To achieve the above objectives, this utility model is implemented through the following technical solution: An electrolytic water hydrogen production device includes a hydrogen production tank, an electrolytic cell formed on the inner wall of the tank, a water inlet on the side wall of the tank, and a hydrogen outlet pipe fixedly penetrating one end of the side wall of the tank. An alarm device is installed inside the electrolytic cell. The alarm device includes a fixed rod, the bottom of which is fixedly installed at the bottom of the inner wall of the electrolytic cell. A rotating rod is rotatably connected to the side wall of the fixed rod. A fixed block is sleeved on one end of the rotating rod, a pressure plate is fixedly connected to the bottom of the fixed block, and an iron ball is fixedly connected to the other end of the rotating rod. Both sides of the fixed rod are penetrated by one end of a sliding rod and slidably connected to one end of the sliding rod. An alarm is fixedly connected to the inner wall of the electrolytic cell.

[0005] Preferably, the pressure plate's displacement trajectory contacts one end of the sliding rod, while the other end of the sliding rod's displacement trajectory contacts the side of the alarm. A limit spring is fitted onto the outer wall of the sliding rod, and the other end of the limit spring is fixedly installed on the side wall of the fixed rod. The function of the limit spring is to reset the sliding rod and end its contact with the alarm after the water level rises, thus stopping the alarm.

[0006] Preferably, the density of the iron ball is greater than the density of the liquid inside the electrolytic cell, the density of the pressure plate is less than the density of the liquid inside the electrolytic cell, and the mass of the pressure plate is greater than the mass of the iron ball. This design ensures that the end of the rotating rod that fixes the iron ball is not affected by the buoyancy of the water, while the end of the rotating rod that fixes the pressure plate is affected by the buoyancy of the water.

[0007] Preferably, the electrolytic cell is equipped with a dust removal device, which includes a vertical rod. The side of the vertical rod is slidably mounted on the inner wall of the electrolytic cell. A vacuum cleaner is fixedly connected to the inner wall of the electrolytic cell. The dust removal device is used to improve the purity of the water and thus enhance the effect.

[0008] Preferably, a switch is provided at the bottom of the vacuum cleaner, the top of the vertical rod is located directly above the vacuum cleaner, the bottom of the vertical rod is provided with a slope, the shape of the slide rod is set to L, and one end of the slide rod contacts the bottom of the vertical rod on its displacement trajectory. The bottom of the vertical rod is provided with a slope so that it can be better driven to rise by one end of the slide rod when it contacts one end of the slide rod.

[0009] Preferably, one end of the vertical rod passes through a limiting block, and the side of the limiting block is fixedly installed on the inner wall of the electrolytic cell. The limiting block is designed primarily to restrict the sliding of the vertical rod.

[0010] This invention provides a device for producing hydrogen through water electrolysis. It has the following advantages:

[0011] (1) This application achieves a more stable and continuous alarm function by coordinating the rise and fall of the water level inside the electrolytic cell with the buoyancy of the water, and by coordinating the rotating rod, fixing block and other components inside the alarm device. When the water level drops to the bottom, the sliding rod automatically moves to start the alarm.

[0012] (2) When the slide bar is moved, it cooperates with the vertical bar inside the dust removal device to clean the impurities inside the electrolytic cell when the water level drops. Attached Figure Description

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below 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, rather than all the embodiments.

[0019] Example 1

[0020] Please see Figure 1-4An electrolytic water hydrogen production device includes a hydrogen production tank 1, an electrolytic cell 2 on the inner wall of the hydrogen production tank 1, a water inlet 3 on the side wall of the hydrogen production tank 1, and a hydrogen outlet pipe 4 fixedly penetrating one end of the side wall of the hydrogen production tank 1. An alarm device 5 is installed inside the electrolytic cell 2. The alarm device 5 includes a fixing rod 51, the bottom of which is fixedly installed at the bottom of the inner wall of the electrolytic cell 2. A rotating rod 52 is rotatably connected to the side wall of the fixing rod 51. A fixing block 53 is sleeved on one end of the rotating rod 52. A pressure plate 54 is fixedly connected to the bottom of the fixing block 53. An iron ball 55 is fixedly connected to the other end of the rotating rod 52. Both sides of the fixing rod 51 are penetrated by one end of a sliding rod 56 and slidably connected to one end of the sliding rod 56. An alarm 57 is fixedly connected to the inner wall of the electrolytic cell 2. The pressure plate 54 contacts one end of the slide rod 56 along its displacement trajectory, while the other end of the slide rod 56 contacts the side of the alarm 57 along its displacement trajectory. A limit spring 58 is sleeved on the outer wall of the slide rod 56, and the other end of the limit spring 58 is fixedly installed on the side wall of the fixing rod 51. The function of the limit spring 58 is to reset the slide rod 56 after the water level rises, ending the contact between the slide rod 56 and the alarm 57, thus stopping the alarm. The density of the iron ball 55 is greater than the density of the liquid inside the electrolytic cell 2, while the density of the pressure plate 54 is less than the density of the liquid inside the electrolytic cell 2, and the mass of the pressure plate 54 is greater than the mass of the iron ball 55. This design ensures that the end of the rotating rod 52 that fixes the iron ball 55 is not affected by the buoyancy of the water, while the end of the rotating rod 52 that fixes the pressure plate 54 is affected by the buoyancy of the water.

[0021] In use, when the water level drops, the pressure plate 54 fixed to one end of the rotating rod 52 is subjected to the buoyancy of the water, and the buoyancy point moves downward. Because the mass of the pressure plate 54 at one end of the rotating rod 52 is greater than that of the iron ball 55 fixed to the other end of the rotating rod 52, the rotating rod 52 is driven to rotate clockwise. When the water level drops to the bottom of the electrolytic cell 2, the pressure plate 54 fixed to the rotating rod 52 will contact one end of the sliding rod 56 that slides through one side of the fixed rod 51. This will cause the alarm 57 fixed to the inner wall of the electrolytic cell 2 to move to one side and press the switch on one side of the alarm 57 to start the alarm. When the water level rises again, the pressure plate 54 fixed to the rotating rod 52 will rise due to the buoyancy of the water and gradually disengage from the sliding rod 56. Under the elastic action of the limit spring 58, the sliding rod 56 will automatically reset and the alarm will end.

[0022] Example 2

[0023] Please see Figure 1-4Based on Embodiment 1, a dust removal device 6 is installed inside the electrolytic cell 2. The dust removal device 6 includes a vertical rod 61, the side of which is slidably mounted on the inner wall of the electrolytic cell 2. A vacuum cleaner 62 is fixedly connected to the inner wall of the electrolytic cell 2. The dust removal device 6 is used to purify the water and thus improve the effect. A switch is provided at the bottom of the vacuum cleaner 62. The top of the vertical rod 61 is located directly above the vacuum cleaner 62, and the bottom of the vertical rod 61 has an inclined surface. The slide rod 56 is L-shaped, and one end of the slide rod 56 contacts the bottom of the vertical rod 61 on its displacement trajectory. The inclined surface at the bottom of the vertical rod 61 is designed to better allow it to be driven upward by the slide rod 56 when in contact with it. One end of the vertical rod 61 passes through a limiting block 63, the side of which is fixedly mounted on the inner wall of the electrolytic cell 2. The limiting block 63 is designed primarily to restrict the sliding of the vertical rod 61.

[0024] In use, based on Embodiment 1, since the slide rod 56 is set in an L-shape, when the slide rod 56 moves to contact the alarm 57, it will cause the other end of the slide rod 56 to move accordingly, thereby causing the other end of the slide rod 56 to contact the bottom of the vertical rod 61 sliding on the inner wall of the electrolytic cell 2. This will cause the vertical rod 61 to move upward under the limiting action of the limiting block 63, thereby causing the top of the vertical rod 61 to accurately contact the switch set at the bottom of the vacuum cleaner 62, thereby causing the vacuum cleaner 62 to perform dust removal on the inside of the electrolytic cell 2.

[0025] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
