The selection of electrode materials is crucial and needs to have good electrical conductivity and corrosion resistance. The diaphragm plays a role in separating the anode and cathode regions to prevent the mixing of products. The design of the electrolytic cell should consider factors such as efficient mass transfer, heat dissipation, and safety. It is widely used in water treatment, sanitation and disinfection and other fields, playing an important role in ensuring water quality safety and public health.

[0003] For the existing electrolytic cell of a sodium hypochlorite generator, in order to ensure the sealing performance and structural strength, a large number of bolts and nuts are used for fastening connection at both ends of the end covers.

[0021] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0022] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0023] Embodiment 1 is as Figures 1 - 4 shown. The present utility model provides an electrolytic cell for a sodium hypochlorite generator, which includes an electrolytic cell body 1. Two fixing rings 2 are fixedly sleeved on the outer surface wall of the electrolytic cell body 1. A set of clamping grooves 3 are opened on the inner surface walls of the two fixing rings 2. A slider 4 is movably inserted into the inner surface walls of the two sets of clamping grooves 3. An installation plate 5 is movably sleeved between the outer surface walls of the two sets of sliders 4. A set of sliding grooves 6 are opened on one side of the outer walls of the two installation plates 5, and the outer surface walls of the two sets of sliders 4 are movably inserted into the two sets of sliding grooves 6. A fixing rod 7 is fixedly connected to one side of the outer walls of the two sets of sliders 4. A worm gear 8 is movably sleeved between the outer surface walls of the two sets of fixing rods 7. A set of arc grooves 9 are opened on one side of the outer walls of the two worm gears 8, and the outer surface walls of the two sets of fixing rods 7 are movably inserted into the two sets of arc grooves 9. A rotating shaft 10 is fixedly inserted into the inner surface walls of the two worm gears 8. A first bearing 11 is fixedly sleeved on the outer surface walls of the two rotating shafts 10. A worm 12 is meshed and connected to the outer surface walls of the two worm gears 8. A turning handle 13 is fixedly sleeved on the outer surface walls of the two worms 12. Two second bearings 14 are fixedly sleeved on the outer surface walls of the two worms 12. A limiting groove 15 is opened on the outer surface wall of each of the two sets of sliders 4. A limiting rod 16 is movably inserted into the inner surface wall of each of the two sets of limiting grooves 15. A pull ring 17 is fixedly connected between the outer surface walls of the two sets of limiting rods 16. A set of springs 18 are fixedly connected to one side of the outer walls of the two pull rings 17.

[0024] The effect achieved by the entire Embodiment 1 is that when it is necessary to disassemble the two end caps 20 for maintenance or repair, first pull the pull ring 17. The pull ring 17 drives a set of limit rods 16 to move outward, so that a set of limit rods 16 are disengaged from the corresponding limit slots 15, thereby releasing the fixed restriction on a set of sliders 4. At the same time, the movement of the pull ring 17 will stretch a set of springs 18, enabling the springs 18 to accumulate elastic potential energy. Subsequently, by rotating the handle 13, the handle 13 drives the worm 12 to rotate, and the worm 12 further drives the worm wheel 8 to rotate. Since a set of arc-shaped grooves 9 are designed on one side of the outer wall of the worm wheel 8, and a fixed rod 7 is movably inserted into the inner wall of each arc-shaped groove 9. As the worm wheel 8 rotates, the positions of a set of arc-shaped grooves 9 move relatively, prompting a set of fixed rods 7 to move along the path of the arc-shaped grooves 9 towards the center of the worm wheel 8. This movement drives a set of sliders 4 fixedly connected to a set of fixed rods 7 to move synchronously, enabling a set of sliders 4 to smoothly slide into the corresponding sliding grooves 6 and finally completely move out from the inside of a set of clamping grooves 3. This process enables the end cap 20 to be easily removed from the fixing ring 2, facilitating cleaning, replacing electrodes or other necessary maintenance work. In this way, the maintenance and repair operations of the equipment are greatly facilitated, and the maintenance efficiency is significantly improved. At the same time, due to the adoption of a multiple locking mechanism, it is ensured that the end cap 20 can maintain a stable fixed state during use, preventing a decrease in electrolysis efficiency or safety problems caused by loosening.

[0025] Embodiment 2 is as Figures 2 - 4 shown. A set of connecting blocks 19 are fixedly installed on the tops of the two mounting plates 5. A set of end caps 20 are fixedly connected between the outer surfaces of the two sets of connecting blocks 19. First embedding grooves 21 are opened on the inner surfaces of the two fixing rings 2 and the bottoms of the two mounting plates 5. A first sealing gasket 22 is movably inserted between the inner surfaces of the four first embedding grooves 21. The bottoms of the two mounting plates 5 are fixedly connected with embedding blocks 23. Two second embedding grooves 24 are opened on the outer surfaces of the two embedding blocks 23. A second sealing gasket 25 is movably inserted into the inner surfaces of the four second embedding grooves 24.

[0026] The effect achieved by the entire Embodiment 2 is that first, two second embedding grooves 24 are opened on the outer surface of the embedding block 23, and a sealing gasket is movably inserted into the inner surface of each of the two second embedding grooves 24. The main function of the two second sealing gaskets 25 is to provide an additional sealing effect. They can effectively prevent the leakage of the electrolyte, ensuring the stability and safety of the internal environment of the electrolytic cell. In addition, a first sealing gasket 22 is movably inserted between the inner surfaces of the two first embedding grooves 21. The first sealing gasket 22 not only further enhances the overall sealing performance of the electrolytic cell, but also reduces the tiny gaps caused by vibration or temperature changes through the optimization of its material and structure, thereby further preventing the leakage of the electrolyte and ensuring the continuity and efficiency of the electrolysis process.

[0027] Working principle: During use, when the two end covers 20 need to be removed for maintenance or overhaul of the equipment, the unlocking step is first performed. This step begins with pulling the pull ring 17. The displacement of the pull ring 17 drives a group of limit rods 16 to move outward until they are completely separated from the group of limit grooves 15 in which they are located, thereby releasing the fixed constraints on a group of sliders 4. At the same time, the movement of the pull ring 17 also pulls a group of springs 18 to stretch. The springs 18 therefore store elastic potential energy to provide reset power for subsequent operations. Subsequently, by rotating the turning handle 13, the turning handle 13 is used as a power input to drive the worm 12 to rotate. The meshing relationship between the worm 12 and the worm wheel 8 causes the worm wheel 8 to rotate accordingly. A group of arc grooves 9 designed on one side of the outer wall of the worm wheel 8 changes its position relatively with the rotation of the worm wheel 8. This change guides a group of fixed rods 7 movably inserted in the inner wall of the arc groove 9 to move along the arc trajectory toward the center of the worm wheel 8. A group of fixed rods 7 then drives a group of sliders 4 connected thereto to move synchronously, so that a group of sliders 4 slide into corresponding The end cover 20 is then moved out of the fixing ring 2 and the locking state of the slider 4 and the end cover 20 is restored.

[0028] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
