Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model Figures 1-6

[0023] ​As shown in the figure, a cleaning device for the production of moving contacts of a single magnetic circuit breaker includes a support frame 1, a cleaning frame 2 and a cleaning component 3. A plurality of waste holes 21 are formed in the bottom plate of the cleaning frame 2, and the cleaning frame 2 is arranged on the support frame 1. The cleaning component 3 is arranged on the support frame 1 above the cleaning box. The cleaning component 3 includes a sliding plate 31, a fixed pipe 32 and a rotating pipe 33. The sliding plate 31 is horizontally slidably arranged on the support frame 1 through a linear guide rail. A first synchronous belt 12 is arranged on the support frame 1, which is in transmission connection with a first motor 11 arranged on the support frame 1 and is fixedly connected with the sliding plate 31. The fixed pipe 32 is fixedly arranged on the sliding plate 31. The rotating pipe 33 is rotatably arranged at the lower end of the fixed pipe 32 and is communicated with the fixed pipe 32. The rotating pipe 33 is in transmission connection with a second motor 34 arranged on the sliding plate 31 through the cooperation of a synchronous belt and a synchronous pulley. A plurality of transmission rods 35 arranged in an annular array along the axis of the rotating pipe 33 are fixedly connected to the rotating pipe 33. A plurality of vertical material pushing rods 351 are fixedly connected to the transmission rods 35. A plurality of cleaning pipes 36 communicated with the rotating pipe 33 and located between adjacent two transmission rods 35 are fixedly connected to the rotating pipe 33. A plurality of cleaning nozzles 361 are arranged on the cleaning pipes 36.

[0024] Specifically, the structure of the rotating pipe 33 rotatably arranged on the fixed pipe 32: An installation convex ring 321 is formed at the lower end of the fixed pipe 32. A water passing hole 322 is formed in the installation convex ring 321, and a rotating shaft 323 is formed at the lower end of the installation convex ring 321. The rotating pipe 33 is composed of an upper pipe 331 and a lower pipe 332 fastened together by bolts. The installation convex ring 321 is placed in the lower pipe 332 so that the rotating shaft 323 is inserted into a rotating hole formed in the lower pipe 332. The upper pipe 331 abuts against the installation convex ring 321 to realize the rotational connection between the rotating pipe 33 and the fixed pipe 32. A sealing ring is arranged between the upper pipe 331 and the installation convex ring 321.

[0025] In the above structure, when cleaning the moving contact of the single magnetic circuit breaker (hereinafter referred to as the moving contact), the moving contact with cleaning is placed in the cleaning frame 2 and laid flat on the bottom plate of the cleaning frame 2, the material-pickup rod 351 is inserted between the moving contact pieces, the fixed pipe 32 is connected to the external water pump, and the second motor 34 drives the rotating pipe 33 to rotate on the fixed pipe 32 through the cooperation of the synchronous wheel and the synchronous belt. The rotating pipe 33 drives the transmission rod 35 and the cleaning pipe 36 to rotate, and the transmission rod 35 drives several material-pickup rods 351 to rotate. The rotating material-pickup rod 351 pokes the moving contact laid flat in the cleaning frame 2, causing the moving contact to continuously flip in the cleaning frame 2. At the same time, the water pump pumps cleaning liquid into the fixed pipe 32. The cleaning liquid entering the fixed pipe 32 enters the cleaning pipe 36 and is sprayed out through the cleaning nozzle 361. The cleaning liquid sprayed from the cleaning nozzle 361 that continuously rotates with the cleaning pipe 36 is sprayed onto the continuously flipping moving contact to The head is rinsed. At the same time, the first motor 11 drives the sliding plate 31 to slide horizontally on the support frame 1 through the first synchronous belt 12, and drives the rotating material-dispensing rod 351 and the cleaning nozzle 361 to move repeatedly above the cleaning frame 2, and repeatedly rinses the moving contact spread in the cleaning frame 2. The oil, dirt, dust and other waste materials flushed are discharged from the cleaning frame 2 from the waste outlet along with the waste water, thereby realizing the cleaning of the moving contact. In the above cleaning process, the rotation and movement of the material-dispensing rod 351 can fully mobilize the moving contact placed in the cleaning frame 2 so that it can be continuously and fully turned over. The rotation and movement of the cleaning nozzle 361 can make the sprayed cleaning liquid fully cover the constantly turning moving contact placed in the cleaning frame 2 and fully rinse all surfaces of the moving contact, thereby achieving a more thorough cleaning effect. In addition, the cleaning process only requires manual loading and unloading operations of the moving contact, which saves manpower and improves cleaning efficiency.

[0026] In addition, on the basis of the above structure, the cleaning frame 2 can be longitudinally slidably arranged on the support frame 1 through a linear guide rail, and the support frame 1 is rotatably provided with a first transmission screw 14 which is screwed on the cleaning frame 2 and is transmission-connected to the third motor 13 arranged on the support frame 1. The third motor 13 drives the first transmission screw 14 to rotate, and the first transmission screw 14 drives the cleaning frame 2 to slide longitudinally on the support frame 1 through threaded cooperation with the cleaning frame 2, so that the cleaning frame 2 is close to or away from the cleaning component 3, which facilitates the loading operation of placing the moving contact into the cleaning frame 2 and the unloading operation of taking the moving contact out of the cleaning frame 2.

[0027] In addition, based on the above structure, the moving paths of the material removing rods 351 on the two adjacent transmission rods 35 are staggered with each other, that is, the rotation paths of the material removing rods 351 on the two adjacent transmission rods 35 with the transmission rod 35 are not in the same yard, so that the material removing rods 351 on the two adjacent transmission rods 35 can stagger the moving contacts, and the moving contacts can be flipped more fully in the cleaning frame 2, thereby achieving a more thorough cleaning effect.

[0028] In addition, based on the above structure, a number of downwardly concave waste discharge grooves 22 are formed on the bottom plate of the cleaning frame 2, and a number of waste discharge holes 21 are opened in the waste discharge grooves 22. The waste and waste water flushed will be concentrated in the waste discharge grooves 22 under the flushing of the cleaning liquid and discharged from the cleaning frame 2 through the waste discharge holes 21, reducing the residue of waste and waste water in the cleaning frame 2, thereby ensuring the cleaning effect.

[0029] In addition, based on the above structure, the material tapping rod 351 is fixedly connected to a brush plate 37 located on one side of the material tapping rod 351, and the brush plate 37 is provided with a number of cleaning bristles 371. When the material tapping rod 351 is inserted between the moving contacts placed in the cleaning frame 2, the cleaning bristles 371 are against the moving contacts. When the material tapping rod 351 moves the moving contacts along with the transmission rod 35, the brush plate 37 moving along with the transmission rod 35 drives the cleaning bristles 371 to move and continuously brush the moving contacts placed in the cleaning frame 2, thereby cooperating with the flushing of the cleaning nozzle 361 to achieve a more thorough cleaning effect.

[0030] In addition, on the basis of the above structure, a blanking push plate 23 is horizontally slidably provided in the cleaning frame 2, and a second synchronous belt 25 is provided on the cleaning frame 2, which is transmission-connected to a fourth motor 24 provided on the cleaning frame 2 and fixedly connected to the blanking push plate 23. A blanking port 26 opposite to the blanking push plate 23 is provided on the side panel of the cleaning frame 2, and a blanking cover 27 fastened to the cleaning frame 2 by bolts is hinged on the blanking port 26. When cleaning the moving contact, the blanking push plate 23 is located at the end of the cleaning frame 2 away from the blanking port 26, and the blanking cover 27 is fastened to the cleaning frame 2 to close the discharge port 26. After cleaning is completed, the third motor 13 drives the cleaning frame 2 to move downward away from the cleaning component 3 so that the material rod 351 withdraws from the moving contact, and then the discharge cover 27 is flipped to open the discharge port 26. The fourth motor 24 drives the second synchronous belt 25 to drive the discharge push plate 23 to move toward the discharge port 26 in the cleaning frame 2, so that the discharge push plate 23 pushes the moving contact that has been cleaned in the cleaning frame 2 to fall out of the cleaning frame 2 from the discharge port 26, thereby facilitating the discharge operation after cleaning is completed, saving manpower and improving the cleaning efficiency.

[0031] In addition, on the basis of the above structure, the blanking push plate 23 includes a fixed plate 231 and a lifting plate 232. The fixed plate 231 is inserted into the support rod 28 provided on the cleaning frame 2, and the lifting plate 232 is longitudinally slidably provided on the fixed plate 231 through the guide rod. The fixed plate 231 is rotatably provided with a second transmission screw 291 which is screwed on the lifting plate 232 and is connected to the fifth motor 29 provided on the fixed plate 231. The fifth motor 29 drives the second transmission screw 291 to rotate, and the second transmission screw 291 drives the lifting plate 232 by screwing it. The lowering plate 232 moves longitudinally on the fixed plate 231 to adjust the distance between the lower end of the lifting plate 232 and the bottom plate of the cleaning frame 2. When the moving contact is placed in the cleaning frame 2, a certain gap is created between the lower end of the lifting plate 232 and the bottom plate of the cleaning frame 2. The lifting plate 232 is driven by the second synchronous belt 25 along with the fixed plate 231 to flatten the moving contact placed in the cleaning frame 2, so that the moving contact is flat on the bottom plate of the cleaning frame 2, thereby facilitating the loading operation before cleaning. After cleaning is completed, the lifting plate 232 moves downward to insert into the moving contact and contact with the bottom plate of the cleaning frame 2, and the unloading operation can be carried out.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
