The inner wall of the toothed chute 206 is slidably connected to the outer wall of the rotating rod 204. Since one side of the toothed chute 206 close to the rotating rod sleeve 202 meshes with the self-provided toothed block on the rotating rod 204, and the other side of the toothed chute 206 away from the rotating rod sleeve 202 is an entire annular groove, when the rotating rod 204 is inserted deep into the toothed chute 206 and rotated by a certain angle, it can be fixed within the toothed chute 206.

[0031] One end of the second rotating rod sleeve 203 away from the rotating rod sleeve 202 is fixedly connected to a fixing plate 207. A number of insertion rods 208 are slidably connected to the inner wall of the fixing plate 207. A spring 209 is fixedly connected to the outer wall of the insertion rod 208. The outer walls of the number of springs 209 are all fixedly connected to the outer wall of the fixing plate 207. The spring 209 can, through its own elastic force, always resist the insertion rod 208, enabling the insertion rod 208 to always be inserted into the positioning hole 205 when the rotating rod 204 is normally fixed. A bolt 210 is threadedly connected to the inner wall of the mounting plate 101. A protective cover 211 is threadedly connected to the outer wall of the bolt 210.

A heat dissipation mechanism 3 is provided on the outer wall of the protective cover 211. The heat dissipation mechanism 3 includes a motor 301. When the motor 301 is started, the motor 301 can drive the transmission shaft 302 to rotate, thereby causing the fan blade 312 to rotate and generate wind to dissipate the heat generated during the operation of the circuit breaker body 102. The outer wall of the motor 301 is fixedly connected to the inner wall of the protective cover 211. The bottom output end of the motor 301 is fixedly connected to the transmission shaft 302 through a coupling. A fan blade 312 is fixedly connected to the outer wall of the transmission shaft 302. A fixed block 303 is fixedly connected to the outer wall of the protective cover 211. The transmission shaft 302 can drive the inner pulley 305. When the transmission shaft 302 rotates, it can drive the inner pulley 305 to rotate, thereby driving the belt 306 to rotate.

[0032] The inner wall of the fixed block 303 is rotatably connected to a rotating shaft 304. Pulley 305 is fixedly connected to the outer walls of both the rotating shaft 304 and the transmission shaft 302. A belt 306 is drivingly connected to the outer wall of the pulley 305. The belt 306 can drive the pulley 305. When the belt 306 rotates, it can drive the outer pulley 305 to rotate, thereby causing the rotating shaft 304 to rotate. A connecting rod 307 is fixedly connected to the outer wall of the end of the rotating shaft 304 away from the pulley 305. The inner wall of the end of the connecting rod 307 away from the rotating shaft 304 is rotatably connected to a fixed shaft 308. A plurality of slide rails 311 are fixedly connected to the outer wall of the end of the protective cover 211 close to the fixed shaft 308. The slide rails 311 can define the movement trajectory of the scraper 309, enabling it to slide only within the slide rails 311 and preventing the scraper 309 from falling. The inner wall of the slide rail 311 is slidably connected to the scraper 309. An arc-shaped groove 310 is formed in the inner wall of the scraper 309. The outer wall of the fixed shaft 308 is slidably connected to the inner wall of the arc-shaped groove 310. When the fixed shaft 308 slides within the arc-shaped groove 310, it can drive the scraper 309 to move, thereby performing a dust removal operation on the heat dissipation holes provided on the protective cover 211.

[0033] A specific application of this embodiment is:

[0034] When the staff needs to use the device, first install the circuit breaker body 102 as a whole on the mounting plate 101, install the protective cover 211 on the mounting plate 101 through the bolts 210 to cover the circuit breaker body 102, and install the mounting plate 101 as a whole on the electric pole 1, align the arc-shaped fixing plate 201 with the mounting plate 103 and the mounting plate 101, insert the rotating rod sleeve 202 and the rotating rod sleeve 203, and pull the multiple insertion rods 208 outward at the same time. The outward movement of the insertion rod 208 will compress the spring 209, and the insertion process The rotating rod 204 is rotated in the middle. When the rotating rod 204 is inserted into the depth of the toothed slot 206 and rotated to a certain angle, the toothed slot 206 is meshed with the toothed block on the rotating rod 204 on the side close to the rotating rod sleeve 202, and the toothed slot 206 is away from the rotating rod sleeve 202. The side of the entire annular groove can be fixed in the toothed slot 206. When the positioning hole 205 on the rotating rod 204 is aligned with the insertion rod 208, the insertion rod 208 is released. At this time, the spring 209 will drive the insertion rod 208 through its own elastic force. The breaker body 102 is reset and inserted into the positioning hole 205 to fix the rotating rod 204 to prevent the rotating rod 204 from detaching by itself, so that the mounting plate 101 and the mounting plate 103 can be fixed on the pole 1 as a whole, and the motor 301 is started. The rotation of the motor 301 will drive the transmission shaft 302 to rotate, so that the fan blades 312 rotate to generate wind force, and the outside air is blown into the protective cover 211 to dissipate heat for the circuit breaker body 102. When the transmission shaft 302 rotates, it will drive the inner pulley 305 to rotate, and then drive the belt 306 to rotate so that the outer pulley The pulley 305 rotates, and the rotation of the outer pulley 305 drives the rotating shaft 304 to rotate in the fixed block 303. The rotation of the rotating shaft 304 drives the connecting rod 307 to rotate so that the fixed shaft 308 performs eccentric circular motion around the rotating shaft 304. The fixed shaft 308 slides in the arc groove 310 and drives the scraper 309 to continuously reciprocate left and right in the slide rail 311, thereby performing dust removal operations on the heat dissipation holes on the protective cover 211 to prevent dust from clogging the protective cover 211 and affecting the heat dissipation efficiency of the device.
