A method for using the power supply vehicle for power equipment maintenance as claimed in claim 8, characterized in that: The following steps are involved: Step 1: When it is necessary to perform maintenance on the electric power equipment, loosen the adjusting screw (91), adjust the position of the sliding rod (92) according to the specifications of the cables and insulators to be cleaned, so that there is a suitable cleaning distance between the cleaning brushes (93), move the sliding rod (92) to a suitable position, and tighten the adjusting screw (91); Step 2: The output end of the second electric linear module (31) moves to drive the third electric linear module (32), the output end of the third electric linear module (32) moves to drive the movable bracket (33), the movable bracket (33) moves to drive the first drive motor mechanism (34), the first drive motor mechanism (34) moves to drive the rotating plate (35), the rotating plate (35) moves to drive the second drive motor mechanism (36), the lower side of the multi-stage hydraulic cylinder (4) is fixedly mounted on the output end of the second drive motor mechanism (36), the output end of the second drive motor mechanism (36) rotates to drive the multi-stage hydraulic cylinder (4) to rotate to a suitable angle, the second drive motor mechanism (36) moves to drive the multi-stage hydraulic cylinder (4), the multi-stage hydraulic cylinder (4) moves to drive the rotating bracket (6), the rotating bracket (6) moves to drive the multiple adjustable cleaning devices (7) and the maintenance device (10), and the multi-stage hydraulic cylinder (4) starts to extend to a suitable position; Step 3: When cleaning the cable or insulator, the double-shaft motor (72) rotates to drive the turntable (81), the turntable (81) rotates to drive the fixed rod (82), the fixed rod (82) rotates to drive the rotating frame (83) to swing back and forth along the rotation trajectory of the fixed rod (82), and the rotating frame (83) swings back and forth to imitate the cleaning action to remove dust on the cable or insulator; Step 4: When maintaining the cable, the output end of the first electric linear module (101) moves to drive the heating plate (102) to move, and the two heating plates (102) are moved close to each other to clamp the ropes, ribbons, etc. on the cable, and the heating plates (102) are powered on, so that the heating plates (102) melt the ropes and ribbons to disconnect them; Step 5: When performing long-distance power supply, open the door (2) on the left side of the power supply vehicle body (1), pull out the fixed bracket (54), move the fixed bracket (54) so ​​that the slider (52) moves on the guide bracket (51), pull out the fixed bracket (54) so ​​that the cable turntable (56) is moved out of the power supply vehicle body (1), connect one end of the cable to the power output end of the power supply vehicle body (1), and connect the other end to the power interface to be powered. When the length of a roll of cable is not enough, pick up the remaining cable turntable (56) from the slot of the fixed bracket (54), and connect the cables on different cable turntables (56) to each other, so as to extend the power supply distance.
