[0041] In a preferred embodiment, as Figure 2 And Figure 3As shown, the protection mechanism 31 further comprises a slide rod 311, a groove is formed on the outer wall of the disconnecting switch 2, the outer wall of both ends of the slide rod 311 is fixedly connected to the inner wall of the groove, and a sliding block 312 is slidingly connected to the outer wall of the slide rod 311, a first spring 313 is connected to the top end of the sliding block 312, the end of the first spring 313 away from the sliding block 312 is connected to the top end of the inner wall of the groove, and the outer wall of the sliding block 312 is arranged with the inner wall of the protective cover 314, and a clamping hole 316 is formed in the outer wall of the clamping plate 315.

[0042] In the above description, the slide rod 311, the sliding block 312 and the first spring 313 are arranged, the protective cover 314 is movably installed on the outer side of the disconnecting switch 2, the disconnecting switch 2 is conveniently protected, and the protective cover 314 is conveniently opened when the disconnecting switch 2 is operated.

[0043] In a preferred embodiment, as shown in Figure 1 and Figure 4 , a second spring 318 is further arranged on the outer wall of the bottom plate 1, a supporting plate 319 is connected to the end of the second spring 318 away from the bottom plate 1, a clamping rod 3110 is connected to the outer wall of one end of the supporting plate 319, and a pulling plate 3111 is connected to the outer wall of the side of the supporting plate 319 away from the clamping rod 3110.

[0044] In the above description, the number of clamping rods 3110 is two, a stress inclined surface is formed in the outer wall of the end of the clamping rod 3110 away from the supporting plate 319, the outer wall of the clamping rod 3110 is matched with the inner wall of the clamping hole 316, the clamping plate 315 can be directly clamped in the clamping hole 317 through the formed stress inclined surface, and the clamping plate 315 is directly clamped and covered; the clamping rod 3110 is matched with the clamping hole 316 during use, and the protective cover 314 is locked.

[0045] In a preferred embodiment, as shown in Figure 2 , Figure 5 and Figure 6 , the anti-misoperation mechanism 32 further comprises an inner sliding groove 322 formed in the inner wall of the sliding groove 321, a roller 323 is movably arranged in the inner wall of the inner sliding groove 322, the end of the roller 323 away from the inner wall of the inner sliding groove 322 is in contact with the outer wall of a connecting sliding block 324, the connecting sliding block 324 is movably arranged in the inner wall of the sliding groove 321, a rotating shaft 325 is rotatably connected to the outer wall of one side of the connecting sliding block 324, a connecting rod 326 is connected to the outer wall of the rotating shaft 325, and the outer wall of the side of the connecting rod 326 away from the rotating shaft 325 is in contact with the outer wall of one end of a limiting rod 327.

[0046] In the above description, by manually dialing the connecting rod 326, the connecting rod 326 drives the connecting slider 324 to move in the inner wall of the sliding groove 321, and the connecting slider 324 drives the roller 323 to move in the inner wall of the inner sliding groove 322. The connecting rod 326 will drive the limiting rod 327 to move. When the connecting slider 324 moves to the horizontal and vertical intersection of the sliding groove 321, the connecting rod 326 can be dialled to the right side, so that the connecting rod 326 drives the limiting rod 327 to rotate to the right side through the rotation of the rotating shaft 325. In this way, the limiting rod 327 can be clamped at the switch of the disconnecting switch 2 (as shown in Figure 3 ), so as to block and limit the switch.

[0047] In a preferred embodiment, as shown in Figure 6 , the number of the inner sliding grooves 322 opened on the inner wall of the sliding groove 321 is two, and the number of the rollers 323 on the connecting slider 324 is two. The two rollers 323 are movably arranged in the inner wall of the inner sliding groove 322.

[0048] In the above description, the connecting slider 324 can be uniformly supported by the left and right sides through the above arrangement, and the frictional force of the connecting slider 324 during movement in the inner wall of the sliding groove 321 can be reduced through the arrangement of the roller 323, so that the movement is more smooth.

[0049] In a preferred embodiment, as shown in Figure 6 , the outer wall of the connecting slider 324 is matched with the inner wall of the sliding groove 321. In this way, the stability of the movement of the connecting slider 324 in the inner wall of the sliding groove 321 can be ensured.

[0050] The implementation principle of the disconnecting switch operating device in the embodiment is as follows:

[0051] In the outdoor environment, the protective cover 314 can be pressed downward, so that the protective cover 314 drives the sliding block 312 to move downward outside the sliding rod 311, and drives the first spring 313 to be extruded and compressed in the moving process. At the same time, with the downward movement of the protective cover 314, the bottom end of the clamping plate 315 will move downward until the clamping plate 315 moves to the inner wall of the clamping hole 317. When the clamping plate 315 moves downward in the inner wall of the clamping hole 317, the bottom end of the clamping plate 315 will contact and extrude the clamping rod 3110. At this time, the bottom end of the clamping plate 315 will contact the stress inclined surface formed on the outer wall of the top end of the clamping rod 3110, so as to extrude and move the clamping rod 3110. At the same time, in the moving process of the clamping rod 3110, the supporting plate 319 can be driven to move outward. With the movement of the supporting plate 319, the second spring 318 will be stretched. After the clamping plate 315 continues to move downward and the clamping hole 316 formed on the outer wall of the clamping plate 315 moves to the position of the clamping rod 3110, the second spring 318 will be reset to pull the supporting plate 319 and the clamping rod 3110 to reset, so that the outer wall of the clamping rod 3110 is clamped and connected to the inner wall of the clamping hole 316. Thus, the clamping and positioning of the clamping plate 315 is completed, and the clamping and positioning of the protective cover 314 is completed. At this time, the protective cover 314 will cover and protect the entire isolation switch 2, so as to prevent outdoor environment from contacting the isolation switch 2, so as to prevent the switch from being opened to cause power failure. When maintenance is needed, the pull plate 3111 can be directly pulled downward to drive the outer wall of the clamping rod 3110 to separate from the inner wall of the clamping hole 316, and then the first spring 313 is reset to drive the sliding block 312 to move upward to drive the protective cover 314 to move upward, so as to open the protective cover 314.

[0052] After the isolation switch is opened during maintenance, the connecting rod 326 on one side can be actuated to drive the connecting sliding block 324 to move rightward in the inner wall of the sliding groove 321. At the same time, the connecting sliding block 324 drives the roller 323 to move in the inner wall of the inner sliding groove 322. At the same time, the connecting rod 326 drives the limiting rod 327 to move rightward. When the connecting sliding block 324 moves to the horizontal and vertical intersection of the sliding groove 321, the connecting rod 326 can be actuated rightward to drive the limiting rod 327 to rotate rightward through the rotation of the rotating shaft 325. In this way, the limiting rod 327 can be clamped on the switch of the isolation switch 2 (as shown in FIG. 12B), so as to block and limit the switch, prevent the switch from being accidentally touched during maintenance to close the isolation switch 2, and cause the risk of electric shock. Figure 3

[0053] It should be noted that in the above description, the isolation switch 2 and its working principle are relatively mature devices in the prior art. The specific model can be selected according to actual needs. The specific power supply mode can be selected to use mains power or a mobile power supply. Details are not repeated here. ​

[0054] The above merely describes preferred embodiments of the present application, and is not intended to limit the scope of protection of the present application.
