As the winding wheel 42 rotates, the tension rope 43 will gradually be wound onto the outer surface of the winding wheel 42. At this time, the other end of the tension rope 43 will drive the connecting block 32, thereby causing the entire movable ladder 3 to begin to move upward along the inner surface of the mounting groove 21, and vice versa.

[0066] The present invention drives the winding wheel 42 to rotate through the first driver 41, winds or unwinds the tension rope 43 on the winding wheel, thereby driving the movable ladder 3 to move on the fixed ladder 2, thereby achieving the raising or lowering of the movable ladder 3, so that inspectors can perform inspections and maintenance at different positions.

[0088] Specifically, in this embodiment, an isolation mesh plate 75 is detachably mounted on one side of the sundry box 72 located at the air inlet pipe 76 , and one end of the air inlet pipe 76 away from the fan 73 abuts against the isolation mesh plate 75 .

[0089] The present invention provides an isolation mesh plate 75 between the fan 73 and the debris collecting box 72 to prevent the fan 73 from sucking in debris when the fan 73 is running.

[0090] In one embodiment, the present invention is used as follows:

[0091] When operators need to go up to inspect substation equipment, Figure 1 As shown, the operator first starts the second driver 541. As the second driver 541 runs, the active rod 542 begins to rotate. At this time, the driven rod 543 will rotate driven by the active rod 542. At the same time, the other end of the driven rod 543 will drive the movable plate and the four connecting plates to move downward as a whole. Finally, the support plate 55 will contact the ground and support the mounting plate 1 as a whole, and the four moving wheels 12 will be off the ground, thereby ensuring the stability of the mounting plate 1 as a whole during the inspection.

[0092] Then the operator starts the first driver 41. As the first driver 41 runs, the winding wheel 42 starts to rotate. As the winding wheel 42 rotates, the tension rope 43 is gradually wound onto the outer surface of the winding wheel 42. At this time, the other end of the tension rope 43 drives the connecting block 32, thereby causing the movable ladder 3 to start moving upward on the fixed ladder 2. Finally, when the limit block 31 moves to the top, the operator can climb to a high place through the fixed ladder 2 and the movable ladder 3 and inspect the equipment.

[0093] When the operator needs to clean up the debris on the ground, the operator aims the trapezoidal debris suction hood 74 at the debris on the ground and starts the fan 73. As the fan 73 runs, the air at the bottom of the debris suction hood 74 will pass through the debris suction hood 74 and the connecting pipe 78 in turn into the interior of the debris collection box 72, and then be discharged to the external environment through the isolation mesh plate 75, the air inlet pipe 76, the fan 73 and the air outlet pipe 77. At the same time, the debris on the ground will enter the interior of the debris collection box 72 with the air flow and be isolated in front of the isolation mesh plate 75, thereby realizing convenient cleaning of the debris on the ground.

[0094] In another embodiment, the use process of the present invention is as follows:

[0095] When operators need to go up to inspect substation equipment, Figure 2 As shown, the operator first starts the second driver 541. As the second driver 541 runs, the connecting rod 47 begins to rotate. At this time, the inner surface of the connecting rod 47 drives the connecting column 49 during the rotation, thereby moving the movable frame 544 downward. Finally, the support plate 55 will contact the ground and support the entire mounting plate 1, while the four moving wheels 12 will leave the ground, thereby ensuring the stability of the entire mounting plate 1 during the inspection.

[0096] Then the operator starts the first driver 41. As the first driver 41 runs, the lead screw 44 starts to rotate, and the two movable blocks 453 start to move toward each other. The movement of the movable block 453 causes the first connecting rod 451 to start rotating. At the same time, the other end of the first connecting rod 451 drives the second connecting rod 452, causing the second beam to also start rotating. Finally, the other end of the second connecting rod 452 drives the connecting block 32, thereby causing the movable ladder 3 as a whole to start moving upward along the fixed ladder 2. Finally, when the limit block 31 moves to the highest point, the operator can climb to a high place through the fixed ladder 2 and the movable ladder 3 and inspect the equipment.

[0097] When the operator needs to clean up the debris on the ground, the operator aims the trapezoidal debris suction hood 74 at the debris on the ground and starts the fan 73. As the fan 73 runs, the air at the bottom of the debris suction hood 74 will pass through the debris suction hood 74 and the connecting pipe 78 in turn into the interior of the debris collection box 72, and then be discharged to the external environment through the isolation mesh plate 75, the air inlet pipe 76, the fan 73 and the air outlet pipe 77. At the same time, the debris on the ground will enter the interior of the debris collection box 72 with the air flow and be isolated in front of the isolation mesh plate 75, thereby realizing convenient cleaning of the debris on the ground.

Such modifications and variations are all within the scope defined by the appended claims.
