The sealing cover plate 304 can seal the front end of the protective bin 200. By setting the sliding hole 312 and the sealing strip 313 The sealing effect can be increased. When the hydraulic telescopic column 101 is opened, the high-temperature resistant insulating column 103 will be pushed to move. The moving high-temperature resistant insulating column 103 will drive the high-temperature resistant high-voltage wire 104 to move in the wire groove 311. During the movement of the high-temperature resistant insulating column 103, the L-shaped connecting rod 300 will be driven to slide in the sealing groove 314 on the protective bin 200, thereby limiting the moving direction of the L-shaped connecting rod 300.

[0028] Working principle of this utility model:

[0029] By providing the protection bin 200 and the rainproof top cover 201, protection can be provided for the high temperature resistant insulating column 103 to prevent rainwater from dripping into the high temperature resistant insulating column 103. The sealing cover plate 304 can seal the front end of the protection bin 200. The sliding hole 312 and the sealing strip 313 can increase the sealing effect. When the hydraulic telescopic column 101 is opened, it will push the high temperature resistant insulating column 103 to move. The moving high temperature resistant insulating column 103 will drive the high temperature resistant high voltage wire 104 to move in the wire groove 311. During the movement of the high temperature resistant insulating column 103, it will drive the L-shaped connecting rod 300 to slide in the sealing groove 314 on the protection bin 200, thereby limiting the movement direction of the L-shaped connecting rod 300. The moving L-shaped connecting rod 300 will drive the U-shaped movable frame 301 to move, and during the movement of the U-shaped movable frame 301, it will slide on the two guide strips 305 respectively through the two guide slots 307, thereby limiting the moving direction of the U-shaped movable frame 301. By setting blocks 306 on both sides of the guide strips 305, the U-shaped movable frame 301 can be prevented from slipping. The continuously moving U-shaped movable frame 301 will drive the two connecting plates 302 to move, so that the connecting plates 302 push the movable plates 303 to move by cooperating with the connecting shafts 309, and the movable plates 303 will drive the sealing cover plate 304 to move. When the sealing cover plate 304 moves, it will drive the sliding holes 312 to separate from the sealing strips 313. The sealing cover plate 304 itself will also slowly move away from the protection chamber 200, and the continuously moving movable plate 303 will slowly move out from between the two limit baffles 400. When the movable plate 303 is placed horizontally, the torsion spring 310 is always in a compressed state. When the movable plate 303 is separated from the limit baffle 400, the movable plate 303 is no longer restricted by the limit baffle 400. The compressed torsion spring 310 will drive the movable plate 303 to flip downward by cooperating with the rotating hole 308. The flipped movable plate 303 will rotate on the connecting shaft 309 through the rotating hole 308, so that the movable plate 303 can achieve the flipping effect. The continuously flipping movable plate 303 will drive the sealing cover plate 304 The sealing cover plate 304 is flipped over so that it can be detached from the front of the protective chamber 200 to avoid blocking the high temperature resistant insulating column 103. At this time, the continuously moving high temperature resistant insulating column 103 can move normally for ignition operation. When the high temperature resistant insulating column 103 retreats and resets, the connecting plate 302 will also move in the opposite direction and follow the reset, so that the connecting plate 302 pulls the movable plate 303 to move and reset, and the movable plate 303 that is moved and reset will be squeezed by the limit baffle 400 and flipped over. During the continuous flipping process, the sealing cover plate 304 will be driven to flip over to the front of the protective chamber 200 again, and then the continuously moving movable plate 303 will drive the sealing cover plate 304 to seal the front of the protective chamber 200.
