Description

Technical Field

[0001] The present invention belongs to the field of inspection equipment, and in particular relates to an inspection device for substation operation and maintenance. Background Art

[0002] With the accelerated development of the State Grid and the improvement of its resource allocation capabilities, the physical form, operational characteristics and functional positioning of the power grid are undergoing profound changes. The equipment level and technological level have been greatly improved, which has put forward high requirements for professional and lean management, and posed major challenges to controlling large power grids and ensuring their safe and stable operation.

[0003] In order to ensure the smooth operation of the power grid, staff are required to patrol and inspect the power grid in the substation. However, with the development of the power grid, the area occupied by the substation continues to expand, and the patrol area of ​​the staff has also increased. Moreover, during the inspection process, since the power grid is generally located at two meters or more, the staff need to constantly check up and down, and carry a certain weight of maintenance tools with them. A single inspection is not only time-consuming and labor-intensive, but also poses certain safety hazards.

[0004] Patent application number CN201920633743.0 proposes a combined tool box for substation operation and maintenance. The patent includes a box body and a cover. One side of the box body is movably connected to the cover via a hinge. The inner wall of the cover is movably connected to a slide groove and a pressure plate. The outer surface of the pressure plate is fixedly connected to a slider. The upper surface of the pressure plate is provided with a spring, and the lower surface of the pressure plate is fixedly connected to a rubber pad. The combined tool box for substation operation and maintenance, through the provision of a mounting plate, serves to facilitate the installation of a limit rod. The limit rod, spring rod, socket plate, and adjustment plate are arranged. When a maintenance tool is placed in the box, the limit rod is pressed down. The adjustment bolt on the adjustment plate squeezes the adjustment plate to the right, clamping the limit rod, thereby confining the maintenance tool inside the box. The sponge layer can prevent the maintenance tool from being scratched, thus playing a role in protecting the maintenance tool. However, this patent does not solve the technical problem raised by this application.

[0005] The patent application number CN202110952304.8 proposes a combined tool box for substation operation and maintenance. The patent proposes that it includes a box body and a box cover arranged on the top of the box body. The left and right sides of the bottom of the inner cavity of the box are fixedly connected to the first partition. When the present invention is working, the starting motor drives the first threaded rod to rotate the first threaded rack and the first bevel gear at the same time. The first threaded rack moves the first extrusion plate, thereby pushing the sliding arc plate to move. The rotation of the first bevel gear drives the second bevel gear to rotate the second threaded rod. The second threaded rod drives the second threaded rack to move the second extrusion plate. The sliding arc plate moves to limit and fix the maintenance tools, thereby preventing the maintenance tools and the tool box from colliding with each other, thereby avoiding damage to the maintenance tools and the tool box. The second extrusion plate moves to fix the document paper, thereby preventing the document paper from wrinkling, and thus avoiding blurring of the data on the document. However, this patent also cannot solve the technical problem raised by this application. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide an inspection device for substation operation and maintenance to solve the problem of inconvenience in the inspection process of the substation.

[0007] In order to solve the above problems, the present invention adopts the following technical solutions:

[0016] Furthermore, the toolbox is arranged parallel to the ladder, the telescopic rod is arranged on a side of the toolbox close to the ladder, and the toolbox is provided with a drawer, and the number of the drawer is at least one.

[0017] Furthermore, an insulating skin is laid on the upper end of the vehicle body.

[0018] The significant beneficial effects achieved by the present invention are:

[0019] 1. The present invention relates to an inspection device for substation operation and maintenance, comprising a vehicle body, a ladder and a telescopic pole with a wireless camera. The ladder and the telescopic pole with a wireless camera are carried on the upper end of the vehicle body to assist in inspection work. The staff can reduce physical exertion and carry more maintenance tools by moving through the vehicle body. When it is necessary to climb up, they can climb up by the ladder. When the inspection height is low, they can perform long-distance viewing by the telescopic pole with a wireless camera. The arrangement of the wireless camera being screwed to the top of the telescopic pole can facilitate the disassembly of the wireless camera. The hollow arrangement of the telescopic pole is used to store the connecting line of the wireless camera to prevent the connecting line of the wireless camera from floating. The present invention enables the staff to operate the vehicle body to carry the ladder and the telescopic pole with the wireless camera to carry out mobile inspection of the substation, which reduces the inspection time and the number of times the staff go up and down to inspect, improves work efficiency, and effectively solves the problem of inconvenience in the inspection process of the substation.

[0020] 2. A toolbox for placing maintenance tools is provided on the vehicle body. The telescopic rod vertically passes through the upper end of the toolbox and is rotatably connected to the upper end of the toolbox through a joint bearing. The connection between the telescopic rod and the toolbox facilitates the storage of the telescopic rod. On the other hand, the setting of the joint bearing can reduce the physical exertion of the staff. When using the telescopic rod with a wireless camera for inspection, the staff only needs to provide a small supporting force to control the telescopic rod. Compared with holding the telescopic rod to inspect equipment located at high places, this undoubtedly reduces the physical exertion of the staff.

[0021] 3. In order to prevent the telescopic rod from leaving the joint bearing during the extension and retraction process, a flange is provided at the bottom end of the telescopic rod to block the telescopic rod. A card holder adapted to the flange is provided at the bottom end of the tool box. The card holder is used to allow the connecting cable of the wireless camera to extend from the bottom end of the telescopic rod. A wire reel with a winding spring is provided on one side of the card holder to store the connecting cable to prevent the connecting cable from being scattered when the telescopic rod is extended or retracted.

[0022] 4. The setting of the ladder rotating and connecting to one side of the upper end of the vehicle body can facilitate the staff to directly connect the ladder to the vehicle body without having to carry the ladder off the vehicle body. The guardrail arranged around the upper end of the vehicle body is used to protect the vehicle body. The revolving door opened on the guardrail is used to block the ladder and facilitate the ladder to be connected. The entry and exit doors arranged symmetrically with the revolving door are used to facilitate the staff to get on and off the vehicle body.

[0023] 5. The ladder is a telescopic ladder that can be adjusted in height for easy use. The wire clip set on one side of the upper end of the ladder is used to clamp the telescopic rod. The wire clip can facilitate the staff to stretch the telescopic rod to the upper end of the ladder and clamp it. The wireless camera can be disassembled for use, which is convenient for checking places that the staff cannot see.

[0024] 6. The staff can bend the flexible sleeve into any shape and use it to extend the wireless camera into a position that is inconvenient for the staff to view.

[0025] 7. In order to conduct inspections at night, at least four evenly distributed headlights are set around the vehicle body. The setting of the headlights can monitor the situation around the vehicle body and facilitate response to emergencies.

[0026] 8. The searchlight connected to the upper end of the toolbox can illuminate high places, making it convenient for staff to inspect and repair high places.

[0027] 9. The toolbox is set parallel to the ladder and the telescopic rod is located on the side of the toolbox close to the ladder, which makes it convenient for the staff to connect the telescopic rod to the line card and use the wireless camera. The drawer set on the toolbox is used to store maintenance tools.

[0028] 10. The setting of the insulation skin on the upper end of the vehicle body can isolate the wires scattered on the ground and prevent the current from being transmitted to the workers on the vehicle body. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] As a further optimization of the present invention, a toolbox 6 is provided on the vehicle body 1, and the telescopic rod 3 vertically passes through the upper end of the toolbox 6. The telescopic rod 3 is rotatably connected to the upper end of the toolbox 6 through a joint bearing 7, and the telescopic rod 3 is slidably connected to the joint bearing 7.

[0048] As a further optimization of the present invention, a flange 8 is provided at the bottom end of the telescopic rod 3, a holder 9 adapted to the flange 8 is provided at the bottom end of the tool box 6, a wire reel 10 is provided on one side of the holder 9, and a winding spring 11 is provided inside the wire reel 10.

[0049] Specifically, the vehicle body 1 can be an electric vehicle or a fuel vehicle with a steering wheel, preferably a flatbed vehicle, a ladder 2 is placed on the upper end of the vehicle body 1, and a groove is provided on one side of the upper end of the vehicle body 1 to match the bottom end of the ladder 2. The ladder 2 is fixed by the groove when moving, and a tool box 6 is fixedly connected to the upper end of the vehicle body 1. The tool box 6 is located on one side of the ladder 2. The tool box 6 is a double-door type. The telescopic rod 3 is hollow inside and vertically passes through the upper end of the tool box 6. The telescopic rod 3 is preferably a telescopic rod 3 for a mop. The telescopic rod 3 and the upper end of the tool box 6 are rotatably connected by a joint bearing 7. The telescopic rod 3 is slidably connected to the joint bearing 7. The outer ring of the joint bearing 7 is fixedly connected to the tool box 6. A flange 8 is provided at the bottom end of the telescopic rod 3 to prevent the telescopic rod 3 from being pulled out of the joint bearing 7. A wireless camera 4 is rotatably connected to the upper end of the telescopic rod 3. There is a card seat 9 that is compatible with the flange 8, and an opening is provided on the side wall of the card seat 9. The setting of the card seat 9 is used to make a certain gap between the bottom end of the telescopic rod 3 and the bottom end of the tool box 6, which is convenient for the connecting wires on the wireless camera 4 to extend out. The hollow setting inside the telescopic rod 3 can conveniently hold the connecting wires of the wireless camera 4 to prevent the connecting wires of the wireless camera 4 from floating outside.
