The film will help the cleaning block to clean the surface of the circuit breaker body. At the same time, if the circuit breaker body has a vacuum leak due to a gap, a negative pressure will be formed inside the circuit breaker body, thereby adsorbing the cleaning film at the gap. Subsequently, the high temperature generated by the circuit breaker body during operation will melt the cleaning film, so that the cleaning film will seal the gap. In this way, the vacuum degree inside the circuit breaker body can be effectively guaranteed and the service life of the circuit breaker can be increased. The setting of the air guide plate can effectively guide the airflow in the hollow column and increase the airflow intensity.

At the same time, the setting of the cleaning particles 8 can effectively scrape and remove the stubborn stains that are difficult to remove on the surface of the circuit breaker body 1, thereby improving the cleaning effect.

[0024] like Figure 3 As shown, an elastic filter plate 9 is arranged above the transmission rod 5, and a plurality of groups of crushing needles 10 are fixed to the outside of the elastic filter plate 9; during operation, when hail falls into the protective plate 2, it will collide with the elastic filter plate 9, and the crushing needles 10 on the outside of the elastic filter plate 9 will directly contact the hail, thereby crushing the hail, so that the hail will be ejected in the form of ice slag during the movement of the buffer spring 3, thereby not affecting the adjacent circuit breaker.

[0025] like Figure 3 to Figure 4 As shown, a guide tube 12 is fixed inside the transmission rod 5, a guide nozzle 11 is fixed on the top of the guide tube 12, the guide nozzle 11 is fixedly connected to the protection plate 2, a liquid storage bag 13 is fixed on one end of the guide tube 12 away from the guide nozzle 11, the liquid storage bag 13 is installed inside the cleaning block 6, a drain pipe 14 is fixed on one end of the liquid storage bag 13 away from the guide tube 12, and the drain pipe 14 is connected with the cleaning block 6; during operation, the broken hail is easier to melt, and the melted hail flows into the guide nozzle 11 through the elastic filter plate 9, and the elastic filter plate 9 can filter the melted water flow at the same time, and the water flow will flow into the guide tube 12 through the guide nozzle 11, and then flow into the liquid storage bag 13 through the guide tube 12, so that during the movement of the cleaning block 6, the water flow in the liquid storage bag 13 will be sprayed out through the drain pipe 14, thereby improving the cleaning effect of the cleaning block 6 on the surface of the circuit breaker body 1, and also can help the circuit breaker body 1 to dissipate heat.

[0026] like Figure 4As shown, a weighted ball 15 is arranged inside the liquid storage capsule 13, and an elastic sheet 16 is fixed between the weighted ball 15 and the liquid storage capsule 13; during operation, during the movement of the cleaning block 6, the weighted ball 15 will pull the elastic sheet 16 back and forth under the action of inertia force to move, and the movement of the elastic sheet 16 will pull the drain pipe 14 to move, thereby causing the drain pipe 14 to deform and increase the internal pressure, thereby causing the water in the drain pipe 14 to spray out, thereby increasing the amount of water sprayed by the cleaning block 6 during the movement, thereby further improving the cleaning effect and ensuring the heat dissipation effect of the circuit breaker in subsequent work.

[0027] like Figure 4 As shown, a guide column 17 is fixed between the liquid storage capsule 13 and the cleaning block 6, and a thermal expansion column 18 is installed inside the guide column 17. A squeezing block 19 is fixed to the side of the thermal expansion column 18 close to the liquid storage capsule 13, and the squeezing block 19 is slidably connected with the guide column 17; when working, a large amount of heat is generated in the circuit breaker body 1 during operation, and this heat is conducted to the thermal expansion column 18, so that the thermal expansion column 18 is heated and expanded. After the expansion, the thermal expansion column 18 pushes the squeezing block 19 to slide in the guide column 17, and the squeezing block 19 moves to compress the liquid storage capsule 13 to deform it, thereby causing the water in the liquid storage capsule 13 to spray out, and the sprayed water falls on the surface of the circuit breaker body 1, so that the collected water is automatically sprayed out when the circuit breaker body 1 is running at high temperature to help the circuit breaker body 1 to cool down.

[0028] like Figure 3 As shown, a focusing plate 20 is fixed inside the protective plate 2, and the focusing plate 20 is fixedly connected to the elastic filter plate 9. A focusing groove is provided on the surface of the focusing plate 20 below the elastic filter plate 9. When working, the focusing plate 20 is designed to effectively gather the water flow after the hail melts and make it flow into the guide pipe 12, thereby achieving the effect of focusing.

[0029] like Figures 2 to 3 As shown, the protection plate 2 is rotatably connected to the outside with multiple sets of transmission wheels 21, and a buffer plate 22 is fixed to the outside of the transmission wheel 21; when working, the setting of the transmission wheel 21 can make the hail contact with the transmission wheel 21 in the process of hitting the protection plate 2 and popping out, and the transmission wheel 21 will slow down the speed of the hail popping out, thereby reducing the impact of the hail on the adjacent circuit breaker after popping out.

[0030] Embodiment 2 like Figures 5 and 6As shown, compared with Example 1, another implementation of the present invention is: a fixing frame 23 is fixed on both sides of the support frame 4, and a hollow column 24 is fixed on one end of the fixing frame 23 away from the support frame 4, and a sliding plug 26 is slidably connected inside the hollow column 24, and a connecting rod 25 is fixed on the top of the sliding plug 26, and the connecting rod 25 is connected through the hollow column 24, and the connecting rod 25 is fixedly connected to the protective plate 2; when working, during the movement of the protective plate 2, it will simultaneously drive the connecting rod 25 to move, and the movement of the connecting rod 25 will push the sliding plug 26 to slide in the hollow column 24, and the sliding plug 26 will generate airflow during the sliding process, and the airflow will be ejected to the surface of the circuit breaker body 1 through the hollow column 24, thereby blowing away the dust brushed off by the cleaning block 6 during the scraping process of the surface of the circuit breaker body 1, thereby ensuring the heat dissipation effect of the circuit breaker body 1 during subsequent work.

[0031] like Figures 5 and 6 As shown, the lower end of the hollow column 24 is rotatably connected with a rotating shaft 27, and a plurality of groups of pneumatic blades 28 are fixed on the outside of the rotating shaft 27. A winding wheel 29 is fixed on the inside of the rotating shaft 27, and a cleaning film 30 is wound around the outside of the winding wheel 29. An air guide plate 31 is arranged above the rotating shaft 27, and the air guide plate 31 is fixedly connected to the hollow column 24. When working, during the process of gas discharge in the hollow column 24, the air flow will blow to the pneumatic blades 28, thereby driving the pneumatic blades 28 to rotate, and the rotation of the pneumatic blades 28 will drive the rotating shaft 27 to rotate, and then drive the winding wheel 29 to rotate, and the winding wheel 29 will rotate after rotating. The film 30 is released, and the released cleaning film 30 will help the cleaning block 6 to clean the surface of the circuit breaker body 1. At the same time, if the circuit breaker body 1 has a vacuum leak due to a gap, a negative pressure will be formed inside the circuit breaker body 1, so that the cleaning film 30 will be adsorbed at the gap. Then, the high temperature generated by the circuit breaker body 1 during operation will melt the cleaning film 30, so that the cleaning film 30 will seal the gap. In this way, the vacuum degree in the circuit breaker body 1 can be effectively guaranteed, and the service life of the circuit breaker can be improved. The setting of the air guide plate 31 can effectively guide the airflow in the hollow column 24 and improve the airflow intensity.

[0032] Working principle: When encountering extreme weather with hail, the hail falling from the sky will collide with the protective plate 2, thereby effectively protecting the circuit breaker body 1 from being directly hit by the hail, and in the process of the hail hitting the protective plate 2, the buffer spring 3 will be deformed under the action of the impact force, thereby buffering the impact force, so that the circuit breaker body 1 can be effectively protected from the impact of hail and the service life of the high-voltage vacuum circuit breaker outdoors can be extended; When the protective plate 2 is subjected to the impact force of the hailstones and the buffer spring 3 is compressed, the protective plate 2 will simultaneously drive the transmission rod 5 to move, and the movement of the transmission rod 5 will drive the cleaning block 6 to move back and forth. During the movement, the cleaning block 6 will simultaneously drive the bristles 7 to scrape the surface of the circuit breaker body 1, thereby effectively removing the dust accumulated on the surface of the circuit breaker body 1 and improving the heat dissipation effect of the circuit breaker body 1 during subsequent work. At the same time, the setting of the cleaning particles 8 can effectively scrape and remove the stubborn stains on the surface of the circuit breaker body 1 that are difficult to remove, thereby improving the cleaning effect; and when the hailstones fall into the protective plate 2, they will collide with the elastic filter plate 9. At this time, the crushing needles 10 on the outside of the elastic filter plate 9 will directly contact the hailstones, thereby crushing the hailstones. In this way, the hailstones will be ejected in the form of ice slag during the movement of the buffer spring 3, thereby not affecting the adjacent circuit breakers; at the same time, the crushed hailstones are easier to melt, and the melted hailstones flow into the guide nozzle 11 through the elastic filter plate 9. At the same time, the elastic filter plate 9 can filter the melted water flow, and the water flow will flow into the guide pipe 12 through the guide nozzle 11, and then flow into the liquid storage bag 13 through the guide pipe 12. In this way, during the movement of the cleaning block 6, the water flow in the liquid storage bag 13 will be sprayed out through the drain pipe 14, thereby improving the cleaning effect of the cleaning block 6 on the surface of the circuit breaker body 1, and at the same time, it can also help the circuit breaker body 1 to dissipate heat; and during the movement of the cleaning block 6, the weighted ball 15 will reciprocate under the action of the inertial force to pull the elastic sheet 16 to move, and the movement of the elastic sheet 16 will pull the drain pipe 14 to move, thereby driving the discharge pipe 14 to deform and increase the internal pressure, thereby causing the water in the drain pipe 14 to spray out, increasing the amount of water sprayed during the movement of the cleaning block 6, thereby further improving the cleaning effect and ensuring the heat dissipation effect of the circuit breaker in subsequent work; and the design of the focusing plate 20 can effectively gather the water flow after the hail melts and make it flow into the inside of the guide pipe 12, thereby achieving the effect of focusing; After the hail, a large amount of water will be stored in the liquid storage capsule 13 and not discharged. At this time, the circuit breaker body 1 will generate a large amount of heat during operation. This heat will be transferred to the thermal expansion column 18, so that the thermal expansion column 18 will expand due to the heat. After the expansion, the thermal expansion column 18 will push the extrusion block 19 to slide in the guide column 17. The extrusion block 19 moves to compress the liquid storage capsule 13 to deform it, so that the water in the liquid storage capsule 13 is sprayed out, and the sprayed water falls on the surface of the circuit breaker body 1. In this way, the collected water is automatically sprayed out when the circuit breaker body 1 is running at high temperature to help the circuit breaker body 1 to cool down. The arrangement of the transmission wheel 21 outside the protection plate 2 can make the hail contact the transmission wheel 21 when it hits the protection plate 2 and pops out. The transmission wheel 21 will slow down the speed of the hail popping out, thereby reducing the impact of the hail on the adjacent circuit breaker after it pops out. During the movement of the protective plate 2, it will simultaneously drive the connecting rod 25 to move. The movement of the connecting rod 25 pushes the sliding plug 26 to slide in the hollow column 24. During the sliding process of the sliding plug 26, airflow will be generated. The airflow will pass through the hollow column 24 and spray to the surface of the circuit breaker body 1, thereby blowing away the dust brushed off by the cleaning block 6 during the scraping process of the circuit breaker body 1, thereby ensuring the heat dissipation effect of the circuit breaker body 1 during subsequent work; and during the gas discharge process in the hollow column 24, the airflow will blow to the pneumatic fan blades 28, thereby driving the pneumatic fan blades 28 to rotate, and the rotation of the pneumatic fan blades 28 drives the rotating shaft 27 to rotate, and then drives the winding wheel 29 to rotate, and the winding wheel 29 is driven to rotate. The reel 29 releases the cleaning film 30 after rotation, and the released cleaning film 30 helps the cleaning block 6 to clean the surface of the circuit breaker body 1. At the same time, if the circuit breaker body 1 has a vacuum leak due to a gap, a negative pressure will be formed inside the circuit breaker body 1, so that the cleaning film 30 will be adsorbed at the gap. Subsequently, the high temperature generated by the circuit breaker body 1 during operation will melt the cleaning film 30, so that the cleaning film 30 seals the gap, thereby effectively ensuring the vacuum degree in the circuit breaker body 1 and improving the service life of the circuit breaker. The setting of the air guide plate 31 can effectively guide the airflow in the hollow column 24 and improve the airflow intensity.
