[0002] The residual chlorine electrode, also known as the residual chlorine sensor or residual chlorine probe, is an online residual chlorine sensor, usually used in conjunction with a residual chlorine detector to form an online residual chlorine monitoring system instrument. It is mainly used to measure the residual chlorine content in water. Its working principle is based on the electrochemical principle, and the concentration of residual chlorine in water is inferred by detecting changes in potential or current on the electrode.

[0003] During the use of existing residual chlorine electrodes, their surfaces are prone to adsorbing and accumulating stains. These impurities will directly affect the accuracy of the measurement results. Users usually need to perform manual cleaning operations regularly. This work not only increases the workload of operators, but may also prolong the overall measurement cycle due to time-consuming cleaning, thereby affecting overall work efficiency. Utility Model Content

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, when it is necessary to clean the impurities generated by the residual chlorine electrode during operation, it is only necessary to throw it into clean water to start it. At this time, due to the electrolysis of water, a large number of bubbles will be generated in the water. These bubbles can quickly remove the impurities on the electrode when they move.

[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1, as Figure 1-Figure 5 As shown, the utility model provides an automatic cleaning device for a residual chlorine electrode, comprising a residual chlorine electrode body 1, an outer wall of the residual chlorine electrode body 1 is provided with an installation groove 2, an outer wall fixed sleeve of the residual chlorine electrode body 1 is provided with an anti-slip pad 3, an outer wall of the residual chlorine electrode body 1 is threadedly connected with a protective sleeve 4, an installation cavity 5 is provided at the bottom of the residual chlorine electrode body 1, a silver chloride electrode 6 is arranged at the top of the inner wall of the installation cavity 5, a mounting seat 7 is arranged on the outer wall of the silver chloride electrode 6, a gold cathode 8 is arranged on the inner wall of the mounting seat 7, a rotating sleeve 9 is provided on the outer wall of the mounting seat 7, a group of paddles 10 is fixedly installed on the outer wall of the rotating sleeve 9, a connecting plate 11 is fixedly installed on the bottom of the rotating sleeve 9, a group of plastic polishing balls 12 are arranged on the top of the connecting plate 11, and the outer walls of the group of plastic polishing balls 12 are in contact with the bottom of the gold cathode 8, and a fixing rod 13 is fixedly installed between the inner walls of the installation groove 2.

[0025] The effect achieved by the entire embodiment 1 is that the anti-slip pad 3 arranged on the outer wall of the residual chlorine electrode can facilitate workers to hold the residual chlorine electrode more stably, and prevent the residual chlorine electrode from falling and being damaged due to factors such as slipping of the palm of the hand and external impact, thereby increasing the time and cost of repairing the residual chlorine electrode. When the electrode is not working, the protective cover 4 can be put on the outside of the electrode to prevent pollutants from entering the inside of the device, causing wear to the internal parts and affecting the detection results. The worker only needs to rotate the protective cover 4 to quickly remove it, so that the electrode can start working. When the residual chlorine electrode is working, the voltage will be transmitted to the inside of the electrolyte through the silver chloride electrode 6 and the gold cathode 8, so as to detect the residual chlorine content in the water. At this time, the relevant impurities will adhere to the surface of the silver chloride electrode 6 and the gold cathode 8 under the action of electrolysis. When the electrode is put into clean water for cleaning, the silver chloride electrode 6 The gold cathode 8 will decompose water through electric current, thereby producing a large amount of hydrogen and oxygen. The related gases will appear in the water in the form of bubbles and continue to diffuse to the outside. When the moving bubbles flow inside the residual chlorine electrode, they will drive a group of paddles 10 to start rotating. At this time, due to the special shape and structure of the paddle 10, when the bubbles pass through the paddle 10, the flow rate on one side is accelerated, while the flow rate on the other side is relatively slow. This difference in flow rate leads to different air pressures on both sides of the paddle 10, generating a force perpendicular to the paddle 10, thus forming a torque that rotates the paddle 10. The rotating paddle 10 will drive the internal rotating sleeve 9 to start rotating inside the mounting seat 7. At this time, the rotating mounting seat 7 drives a group of plastic polishing balls 12 to rotate on the surface of the gold cathode 8 through the connecting plate 11 to remove impurities on the surface of the gold cathode 8.

[0026] Embodiment 2, as Figure 2-Figure 5 As shown, the outer wall of the fixing rod 13 is movably sleeved with a toothed block 14, and the inner wall of the mounting groove 2 is movably inserted into the outer wall of the toothed block 14, a spring 15 is fixedly installed on one side of the outer wall of the toothed block 14, and one side of the outer wall of the spring 15 is fixedly connected to the inner side of the mounting groove 2.

[0027] The effect achieved by the entire embodiment 2 is that it is only necessary to place the device in a beaker or other container filled with clean water, and pull the toothed block 14 to make it rotate on the surface of the fixed rod 13 and stretch the spring 15 to extend from the inside of the mounting groove 2. It is only necessary to clamp the teeth of the toothed block 14 on the outer wall of the container, and the stretched spring 15 will clamp the toothed block 14, thereby fixing the position of the residual chlorine electrode and preventing a large number of bubbles in the water from floating up and bursting, causing the residual chlorine electrode to continuously move, thereby colliding with the beaker wall or other hard objects, causing scratches or damage to the electrode surface.

[0028] Working principle: In order to ensure the stable operation and extend the service life of the residual chlorine electrode, an anti-slip pad 3 is specially designed on its outer wall. This considerate design effectively helps workers to hold it firmly and avoid the electrode from falling and being damaged due to hand slippage or accidental external impact, thereby reducing unnecessary maintenance time and cost. In the non-working state, the protective cover 4 can be easily put on the outside of the electrode to form a barrier to prevent pollutants from invading the interior of the equipment, protect internal components from wear and tear, and maintain the accuracy of the test results. Workers only need to simply rotate the protective cover 4 to quickly disassemble it, so that the electrode can be quickly put into work. When the residual chlorine electrode is started, it uses the precise silver chloride electrode 6 and the gold cathode 8 to work together to accurately transmit the voltage to the electrolyte to detect the residual chlorine content in the water. In this process, the electrolysis will cause some impurities to adhere to the surface of the electrode. To clean these impurities, just place the electrode in clean water and pull the toothed block 14 to make it move along the solid The fixed rod 13 rotates and stretches the spring 15, extending out from the mounting groove 2, and then the teeth of the toothed block 14 are firmly clamped on the edge of the container. The tension of the spring 15 is used to ensure the stability of the electrode, avoid the electrode shaking caused by the bubbles in the water floating up and bursting, and prevent it from colliding with the container wall or other hard objects to cause damage. During the electrolysis process, the silver chloride electrode 6 and the gold cathode 8 decompose water molecules through electric current to generate hydrogen and oxygen. The bubbles formed float and diffuse in the water. When these bubbles flow inside the electrode, they will drive a group of special paddles 10 to rotate. The unique shape and structure of the paddle 10 make the flow velocity on both sides uneven when the bubbles pass through, resulting in an air pressure difference, thereby forming a rotational torque, driving the paddle 10 and the connected rotating sleeve 9 to rotate in the mounting seat 7. As the mounting seat 7 rotates, a group of plastic polishing balls 12 connected by the connecting plate 11 rotate on the surface of the gold cathode 8, effectively removing impurities attached thereto, and ensuring the continuous and efficient operation of the electrode.

[0029] 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.
