In the normal maintenance and use process, the maintenance platform 2 is lifted by the lifter 1 and is protected by the protective fence 3 arranged at the top of the maintenance platform, so that maintenance personnel can normally maintain the photovoltaic panel;

when the photovoltaic panel is required to be replaced and maintained, a maintenance person pulls the outer expansion plate 422 outwards, the outer expansion plate 422 drives the guide groove 423 to move when moving, so that relative sliding occurs between the rotating shaft 421 and the guide groove 423, when the guide groove 423 moves to the other end of the guide groove 423 to be in contact with the rotating shaft 421, an operator can rotate the outer expansion plate 422 outwards, the outer expansion plate 422 rotates 180 degrees to be inserted into the side face of the guide groove 423, in the process, the maintenance person pulls the inserting connection rod 542 outwards, the inserting connection rod 542 moves to drive the limiting piece 543 to move to compress the compression spring 544, after the outer expansion plate 422 rotates 180 degrees, the maintenance person loosens the inserting connection rod 542 at the moment, under the resilience of the compression spring 544, the limiting piece 543 reversely moves and drives the inserting connection rod 542 to be inserted into the limiting groove 545 on the outer expansion plate 422, so that the inserting connection rod 542 can limit rotation of the outer expansion plate 422, and stability of the outer expansion plate 422 in the outer expansion using process is good.

After the outer expansion plate 422 is stably completed, the maintainer pulls out the front fence 31 and the side fence 32 on the maintenance platform 2 and inserts the front fence 31 and the side fence 32 into the inserting groove 51 on the outer expansion plate 422, so that the front fence 31 and the side fence 32 can protect the side of the outer expansion plate 422, and the maintainer can perform maintenance operation with better safety.

After that, maintenance personnel can rotate the support pipes 532 downwards and pull the support pipes 532 downwards, so that relative sliding can occur between the support pipes 532 which are sleeved in sequence, the lowest support pipe 532 is in stable contact with the ground, when the support pipes 532 are pulled outwards, the air pressure inside one end of the support pipes 532 close to the pressure control groove 5331 is rapidly reduced, the part of the support pipes is in a negative pressure state, the air flow of the through groove 5335 cannot meet the neutralization of the negative pressure inside the support pipes, therefore, the baffle 5337 can be subjected to traction force moving towards the inside of the support pipes 532, the baffle 5337 is separated from the notch of the pressure control groove 5331, at the moment, the outside air can directly enter the support pipes 532 from the notch of the pressure control groove 5331, the relative sliding speed between two adjacent support pipes 532 is relatively high, and the support pipes can be rapidly spread.

Then, maintenance personnel stand at the outer expansion plate 422 and carry out maintenance operation, and can control the hydraulic cylinder 412 to start, make its flexible end stretch out, because its both ends respectively with set up in the bearing groove 413 inside and accept the fixing base 414 of board 411 bottom and rotate and be connected, and, hydraulic cylinder 412 initial state is in the inclined state, therefore when hydraulic cylinder 412 flexible end stretches out, accept the board 411 and can rotate the slope, make its inclination can keep close the state with the photovoltaic board, then control lift 1 adjusts the position height of accepting the board 411, make the board 411 be close to the bottom of photovoltaic board, and promote the photovoltaic board, make its bottom fall on accepting board 411, then carry out auxiliary support through accepting board 411 surface's support strip 415, then the operator again control lift 1 carries out upward to accepting board 411, make accepting board 411 carry out the complete bearing, then the operator again control hydraulic cylinder 412 flexible end is continued stretching out, make the gradient of accepting board 411 increase, thereby make the board 411 that bears the photovoltaic board 411 can follow the place of single axle photovoltaic support and remove down through swinging down and change to the work of photovoltaic board more convenient for the maintenance.

When the receiving plate 411 carrying the photovoltaic panel moves downward under the drive of the lifter 1, the downward movement speed is slower, and in the process, the adjacent two support pipes 532 slide each other and enter the inside of the outer support pipe 532, so that the internal air pressure of the outer support pipe 532 is increased, at this time, the high-pressure air in the outer support pipe 532 can only be discharged from the through groove 5335 to the pressure control groove 5331 and discharged to the outside through the pressure control groove 5331, so that the mutual approaching movement speed between the adjacent two support pipes 532 is slower, and thus the stable support effect is played on the outer expansion plate 422 in the downward movement process of the outer expansion plate 422, and the support strength of the outer expansion plate 422 is higher.
