[0023] A substation frame includes a substation frame crossbeam, wherein the substation frame crossbeam is any one of the above substation frame crossbeams.

[0024] Working Principle: Installation Process: When docking, align the positioning pin 202 of the first docking plate 201 with the positioning pin hole 204 of the second docking plate 203 and insert it until the first docking plate 201 and the second docking plate 203 are in contact with each other; Rotate the linkage cover plate 206 in the movable cavity 205 so that the locking pin 207 passes through the locking hole 208 of the uppermost positioning pin 202, completing the initial fixation; Flip the L-shaped clamping plates 301 on both sides of the first docking plate 201 so that they fit into the second clamping slots 302 of the second docking plate 203. At this time, the first linkage block 304 and the second linkage block 306 pass through the first clamping slots 303 of the L-shaped clamping plates 301 respectively. The fastening nut 308 is rotated to be threadedly connected with the threaded rod 305 and tightened. The L-shaped clamping plate 301 is locked through the cooperation of the connecting rod 307 and the threaded rod 305 to complete the crossbeam docking.

[0025] De-icing operations: The first motor 402 is started, and drives the first driving gear 403 to rotate, and at the same time drives the first driven gear 405 to rotate.

The rotation of the second driven gear 507 drives the driven rod 504 to rotate, and the linkage roller 505 is driven to rotate, so that the rubber plate 506 alternately hits the first reinforcement rod 104 and the second reinforcement rod 105, thereby shaking off the ice on the surface. The auxiliary wheel 508 on the top of the second linkage frame 501 rolls along the second main support 102 and the third main support 103 to ensure smooth movement of the de-icing mechanism.
