Description

Technical Field

[0001] The utility model relates to the technical field of circuit distribution network, in particular to a maintenance device used for circuit distribution network operation. Background Art

[0002] The power distribution network receives electricity from the transmission grid or regional power plants and distributes it locally or in stages according to voltage to various users through distribution facilities. It is composed of overhead lines, cables, towers, distribution transformers, disconnectors, VAR compensators, and other ancillary facilities, playing a crucial role in distributing electricity within the power grid. During maintenance on the power distribution network, workers need to carry intelligent electronic devices and repair tools to the fault site. These workers typically place tool boxes and other maintenance equipment on the ground and bend over to retrieve them. However, the environments and spaces where repairs are needed are often complex and cramped, making it difficult for workers to reach their tools, hindering maintenance work.

[0003] Patent No. CN213753470U in the prior art discloses a circuit distribution network operation and maintenance device, which relates to the technical field of circuit distribution network-related equipment. The device comprises a housing, a fixed box disposed within the housing, a plurality of connecting rods fixedly connected to both sides of the fixed box, one end of each of the connecting rods being fixedly connected to the inner wall of the housing, a slide rail fixedly connected to both sides of the fixed box, a first tool box slidably connected between the two top slide rails, and a second tool box slidably connected between the two bottom slide rails, a linkage portion disposed on both sides of the fixed box, two slide bars slidably connected to both sides of the housing, and a single limit plate fixedly connected to one side of each of the two slide bars on the same side. In the present utility model, two height adjustment portions are screwed onto two mounting bases, respectively. The height of the height adjustment portion can then be increased by rotating a knob according to the actual needs of the operator, allowing the operator to conveniently access maintenance tools without having to frequently bend over.

[0004] However, there are the following disadvantages: in the process of repairing the circuit, if a narrow space is encountered, most of the horizontal spaces are relatively narrow. When the horizontal space is narrow, the above-mentioned utility model cannot open the tool box, and the lifting mechanism of the above-mentioned utility model cannot adjust the height of the tool box in real time. When the road surface is uneven, the contact area between the two height-adjusting parts and the ground is small, the center of gravity is unstable, and it is easy to tilt and slip. Therefore, a maintenance device for circuit distribution network operation is needed. Utility Model Content

The second rotating bar 49 is rotatably installed on the second supporting block 410. The first motor 41 is started, and the first motor 41 drives the first screw 42 to rotate. The rotation of the first screw 42 drives the first supporting block 46 and the second supporting block 410 to move. The first supporting block 46 and the second supporting block 410 move at the same time to drive the tool box 3 to move. The tool box 3 is moved out of the maintenance box 1, and the staff can use the tools in the tool box 3. When not in use, the first motor 41 is rotated in the opposite direction to store the tool box 3 into the maintenance box 1. This arrangement can drive the tool box 3 to be extended and retracted, which is convenient for the staff to use and store.

[0027] Further, refer to Figure 2 A support rod 411 is installed in the maintenance box 1, and the first screw rod 42 is rotatably installed in the support rod 411. The setting of the support rod 411 can support the first screw rod 42 so that the first screw rod 42 can rotate normally.

[0028] Further, refer to Figure 2 A rotating block 412 is installed on the first support block 46, and the first rotating bar 45 is rotatably installed on the rotating block 412. The setting of the rotating block 412 can connect the first rotating bar 45 and the first support block 46, so that when the first rotating bar 45 rotates, it can drive the first support block 46 to move.
