[0030] During specific use, when clearing ice and snow on the power maintenance cables, the power maintenance line ice and snow clearing device needs to be kept stable. The rotation of the plurality of second drive motors 301 is used to drive the first double-track gear 302 to rotate, so that the first double-track gear 302 drives the corresponding two first chains 303 to rotate during the rotation, so that the first chain 303 drives the first driven gear 304 to rotate while rotating, and the corresponding balancing roller 305 is driven to rotate by the rotation of the first driven gear 304, and the balancing roller 305 moves back and forth on the power maintenance cable, and the damping rod 307 on the protective shell 306 is used to alleviate the bumps of the balancing roller 305 during the movement to ensure the smooth movement of the power maintenance line ice and snow clearing device.

[0031] like Figure 4 As shown, the ice crushing mechanism 4 includes two groups of fixed connecting rods 401 fixedly connected to the bottom end of the top of one end of the overall frame 1, the bottom ends of the two groups of fixed connecting rods 401 are fixedly connected with an arc-shaped limiting cylinder 402, the outer side of the arc-shaped limiting cylinder 402 is symmetrically sleeved with two symmetrical gear rings 403, the outer side of the gear ring 403 is fixedly connected with a second gear 404, the top of the second gear 404 is meshed and connected with a transmission gear 405, one side of the transmission gear 405 is fixedly connected with a transmission motor 406, and the bottom end of the transmission motor 406 is fixedly connected to the top of one end of the arc-shaped limiting cylinder 402; A plurality of second rotating gears 407 are meshed and connected between the gear rings 403, and a connecting shaft 408 is fixedly connected to the bottom end of each second rotating gear 407, and a snow removal brush 409 is fixedly connected to the bottom end of the connecting shaft 408, and the connecting shaft 408 is interlaced and movably connected with the inner wall of the arc-shaped limiting cylinder 402; The second electric telescopic rod 4010 is fixedly connected to both sides and the top side of the arc-shaped limiting cylinder 402 , and the telescopic end of the second electric telescopic rod 4010 is fixedly connected to a scraper 4011 .

[0032] During specific use, the transmission motor 406 is rotated to drive the transmission gear 405 to rotate, and the rotation of the transmission gear 405 makes it easy to mesh and rotate with one of the second gears 404, so that when the second gear 404 meshes and rotates, it drives the gear ring 403 to rotate, which is convenient for meshing and driving a plurality of second rotating gears 407. When each second rotating gear 407 rotates, it also drives the connecting shaft 408 to rotate, thereby driving the snow removal cleaning brush 409 to rotate the cable to clean ice and snow.

[0033] like Figure 7 As shown, the moving mechanism 5 includes a moving frame 501 fixedly connected to one end of the L-shaped fixed frame 102, a plurality of small motors 502 are fixedly connected to the outer side of the moving frame 501, a transmission end of each small motor 502 is fixedly connected to a second double-track gear 503, a gear chain 504 is meshingly and transmission-connected to the outer side of the second double-track gear 503, one end of the gear chain 504 is transmission-connected to a second driven gear 505, one side of the second driven gear 505 is movably connected to the telescopic connection of an electric hydraulic cylinder 506, the top of the electric hydraulic cylinder 506 is movably connected to the side of the moving frame 501, a third electric telescopic rod 507 is fixedly connected to the inner side of the moving frame 501, a deicing scraper 508 is fixedly connected to the telescopic end of the third electric telescopic rod 507, and a small moving roller is fixedly connected to one side of the second driven gear 505.

[0034] During specific use, when clearing ice and snow on the cables of power maintenance equipment, in order to facilitate the movement of the ice and snow clearing device for the power maintenance lines, the ice and snow on the outside of the cables on the power maintenance equipment are quickly cleared, and the second double-track gear 503 is driven to rotate by the rotation of a number of small motors 502, and the two gear chains 504 on the outside are driven to rotate by the rotation of the second double-track gear 503, so that the gear chain 504 drives the corresponding second driven gear 505 to rotate during the transmission process, so as to drive the small moving roller on one side to move on the cable for de-icing. At the same time, in order to adjust the fixing force with the cable crawling, the telescopic adjustment of the electric hydraulic cylinder 506 is convenient to adjust the fitting force between the small moving roller and the cable, so as to facilitate the mobile de-icing of the power equipment.

[0035] A switch panel is fixedly connected to one side of the overall frame 1, and a protective layer is fixedly connected to the surface of the switch panel.

[0036] The surface of the switch panel is fixedly connected with the first drive motor control switch, the electric telescopic rod control switch, the second drive motor control switch, the transmission motor control switch, the second electric telescopic rod control switch, the small motor control switch, the electric hydraulic cylinder control switch and the third electric telescopic rod control switch.

[0037] A line ice and snow clearing method is implemented based on the above-mentioned power maintenance line ice and snow clearing device, and specifically includes the following steps: Using the moving mechanism 5, the rotation of the small motor 502 drives the second double-track gear 503 and the second gear 404 chain 504 to transmit, so that the second driven gear 505 and the small moving roller move along the power cable to the position that needs to be cleaned. Adjust the extension and contraction of the electric hydraulic cylinder 506, adjust the contact strength between the small moving roller and the cable, so that the device moves stably and tightly along the cable.

[0038] Before breaking the frozen ice on the cable, the snow on the cable is first cleared. The snow-clearing roller 2013 on the lifting frame 2012 is fitted with the power maintenance cable through the telescopic adjustment arm 2011 of the first electric telescopic rod 2014. The snow-clearing roller 2013 rolls along the cable to clear the snow on the cable.

[0039] The ice-breaking mechanism 2 is started, and the first rotating gear 202 is driven to rotate by the transmission of the first driving motor 201. The first rotating gear 202 is engaged to drive the rack 203 to move up and down, and adjust the opening and closing size of the two crushing connecting frames 205 driven by the movable pin 204. Through the cyclic rotation of the first driving motor 201, the limiting rod 209 inside the sliding groove 206 is limited by the first gear 2010, and the two crushing connecting frames 205 are controlled to move closer or farther, thereby controlling the spring 207 to swing, so that the crushing head 208 breaks the frozen ice on the cable.

[0040] After breaking the ice, the ice crushing mechanism 4 is started to crush the ice. The transmission motor 406 drives the transmission gear 405 to rotate, meshes with one of the second gears 404 to rotate, and drives the second gear 404 circle 403 and the second rotating gear 407 to rotate. The second rotating gear 407 drives the connecting shaft 408 and the snow removal cleaning brush 409 to rotate to clean the crushed ice on the cable. At the same time, the second electric telescopic rod 4010 drives the scraper 4011 to clean the inside of the arc-shaped limit cylinder 402 to ensure that there is no residual crushed ice.

[0041] During the whole cleaning process, the balancing mechanism 3 always works to keep the device stable. The second driving motor 301 drives the first double-track gear 302 to rotate, and drives the balancing roller 305 to move on the cable through the first chain 303 and the first driven gear 304. The protective shell 306 and the damping rod 307 provide additional stability and shock absorption effect.

[0042] When the ice and snow on the power cables are completely cleared, the moving mechanism 5 is used to move the device to the next position that needs to be cleaned, and the above steps are repeated to clean.
