Description

Technical Field

[0001] The present invention relates to the technical field of power grid maintenance, and in particular to a large-scale power grid power safety maintenance device. Background Art

[0002] In the power system, it is necessary to conduct regular inspections of the power grid, usually using drones, helicopters or manual inspections, to promptly detect and deal with potential faults or problems. When cable equipment fails, troubleshooting and repair work is carried out;

[0003] Regarding the above inspection methods, manual inspection is inefficient and has certain safety risks, while helicopter inspection is too costly. Therefore, drone inspection and maintenance is a more common method. Drone inspection and maintenance mainly involves loading a camera on the drone and flying it along the cable. During the flight, the camera captures the cable image to check for damage and other problems.

[0004] However, this method also has some shortcomings in actual use. For example, the camera can only shoot one side of the cable when shooting the picture, so the back of the cable cannot be inspected. If it flies around the cable, it will be time-consuming and labor-intensive, and will also lead to low maintenance efficiency. Therefore, in order to solve the above shortcomings, this application proposes a large-scale power grid safety maintenance equipment. Summary of the Invention

[0038] Example, by Figure 1-15The present invention includes a drone 1, a traction device 2 is installed at the bottom of the drone 1, and a shooting device 3 is installed at the bottom of the traction device 2, the traction device 2 includes a shell 21, and side panels 29 are fixedly connected on both sides of the bottom of the shell 21, and an electromagnet 291 is embedded in the bottom of the side panel 29, and the shooting device 3 includes a U-shaped plate 31, and iron plates 32 are fixedly connected to the tops of both sides of the U-shaped plate 31, and the electromagnet 291 and the iron plate 32 are magnetically connected. The shooting device 3 is magnetically connected to the bottom of the traction device 2 through the electromagnet 291 and the iron plate 32. When not in use, the shooting device 3 is magnetically fixed to the bottom of the traction device 2, which can improve the stability of the shooting device 3 located at the traction device 2, that is, under the drone, to prevent it from shaking and affecting the stability of the drone 1 flight. When it is necessary to release the fixation of the shooting device 3, it is only necessary to cut off the power to the electromagnet 291 to make it have no magnetic attraction, and then the iron plate 32 will no longer be magnetically fixed.

[0039] The shell 21 is fixedly connected to the bottom of the drone 1, and the traction device 2 also includes a shaft 23, which is movably connected to the inside of the shell 21.

When the traction rope 25 is extended so that the shooting device 3 is put on the cable and is towed and moved by the traction device 2 and the drone 1, the drone 1 will inevitably fly in front of the shooting device 3, but the extended lengths of the two traction ropes 25 are the same. Therefore, the herringbone elastic rope 26 can adaptively stretch at this time, so that when the drone 1 flies forward, the two traction ropes 25 are basically in a straightened state. At the same time, the elastic force of the herringbone elastic rope 26 can also prevent the shaking of the shooting device 3 when moving on the cable from being directly pulled to the drone 1 through the traction rope 25 to affect its flight stability.

[0042] The shooting device 3 also includes two limiting mechanisms 35, which are respectively connected to both sides of the shooting device 3. Notches 36 are provided on both sides of the shooting device 3. The limiting mechanisms 35 pass through the notches 36. The U-shaped plate 31 is movably connected to two upper rollers 33 distributed front and back. The top of the U-shaped plate 31 is fixedly connected to an upper camera 34, and the upper camera 34 is located between the two upper rollers 33. The limiting mechanism 35 includes a mounting plate 351, which is movably connected to the notch 36 through a hinge. The outer side of the mounting plate 351 is movably connected to two electric push rods through a hinge seat. 358, the top of the second electric push rod 358 and the bottom of the iron plate 32 are movably connected by a hinge seat, and the inner side of the mounting plate 351 is slidably connected to a fixing rod 352, and the end of the fixing rod 352 is movably connected to a lower roller 353, and the lower roller 353 is located directly below the upper roller 33. The notch 36 can be used to embed the mounting plate 351, and the mounting plate 351 can be pulled by the second electric push rod 358 to rotate to the outside of the U-shaped plate 31 in a horizontal direction. At this time, all the structures on the inner side of the mounting plate 31 are located on the outside of the U-shaped plate 31, so it will not affect the U-shaped plate 31 being put on the cable, or being removed from the cable, and there will be no obstruction or interference with the cable during the period.

[0043] The inner side of the mounting plate 351 is fixedly connected to a limiting sliding sleeve 355, and the end of the fixing rod 352 away from the lower roller 353 is fixedly connected to the limiting slider 354, and the limiting slider 354 is slidably connected to the inside of the limiting sliding sleeve 355.

An electric push rod 357 is fixedly connected between the bottom plate 356 and the fixing rod 352. During normal use, the electric push rod 357 can push the fixing rod 352 and the lower roller 353 upward, thereby cooperating with the upper roller 33 to clamp the cable, so that the shooting device 3 can be stably put on the cable and pulled and moved, and since the distance between the upper roller 33 and the lower roller 353 is adjustable, it is suitable for maintenance use of cables of different models.

[0044] A triangular oblique block 38 is fixedly connected to the inner side of the mounting plate 351, and a side camera 39 is fixedly connected to the inclined surface of the triangular oblique block 38.

[0045] Two blocks 37 are fixedly connected to both sides of the U-shaped plate 31, and the notch 36 is located between the two blocks 37. The notch 36 extends to the inside of the mounting plate 351. The block 37 can play a blocking and limiting role when the mounting plate 351 rotates to the inside of the notch 36, thereby preventing the mounting plate 351 from rotating excessively and causing the position of the lower roller 353 and the side camera 34 to be offset.

[0046] Working principle:

[0047] When in use, the remote-controlled drone 1 flies above the cable, then moves down to a certain height so that the U-shaped plate 31 is sleeved on the cable, and the upper roller 33 is pressed on the cable, then the electric push rod 2 358 is started to push the mounting plate 351 to rotate downward until the mounting plate 351 is rotated from horizontal to vertical and is located inside the notch 36. At this time, the lower roller 353 is located under the cable, and then the fixing rod 352 can be pushed up by the electric push rod 1 357, that is, the lower roller 353 moves up to cooperate with the upper camera 34 to clamp the cable. At this time, the upper camera 34 and the two side cameras 39 are respectively located directly above and diagonally below the two sides of the cable, shooting the cable in a triangular shape to ensure that the cable can be shot in all directions without any damage. For the inspection of blind spots, after the position of the shooting device 3 is in place, the drone 1 can be controlled to fly to a certain height to avoid accidental contact and interference with the cable during its operation. During this period, it can be driven by the motor 27, and then the meshing transmission of the two bevel gears 28 drives the shaft 23 and the double-groove rope pulley 24 to rotate. When the double-groove rope pulley 24 rotates, the traction rope 25 can be extended to a certain length. At this time, the traction device 2 follows the drone 1 to move up a certain height away from the shooting device 3, and then the drone 1 is remotely controlled to fly along the cable at a certain distance, and the shooting device 3 on the cable is pulled by the traction rope 25 in the traction device 2 to move. When removing the shooting device 3 from the cable, only the above steps need to be reversed.

[0048] When carrying out the expansion loading and cleaning of the cleaning structure, first load the expansion plate frame 4 onto the side surface of the traction device 2. The loading through hole 403 at the corner of the expansion plate frame 4 can provide a loading hole position. After the expansion plate frame 4 is assembled and fixed, the positioning buckle sleeve 702 of the positioning column sleeve 7 can be covered on the positioning shaft seat 5 to achieve alignment and advancement. Then, the end of the threaded loading shaft frame 8 is aligned with the internal threaded carrier tube 6. The threaded loading shaft frame 8 can be rotated and pushed into the internal threaded carrier tube 6 to achieve insertion and fixation, thereby achieving alignment of the telescopic longitudinal cylinder 9, the motor group 11 and the insulation. Fixing and supporting the cleaning brush disc 12; when performing the cleaning action, the electric push rod 10 drives the longitudinal support sleeve 901 and the longitudinal sliding liner 902 to slide, so as to adjust the height position of the bottom motor group 11 and the insulation cleaning brush disc 12. When it is adjusted to the required height position, the reduction motor 1104 can be used to drive the insulation cleaning brush disc 12 to rotate, so that the bottom of the insulation cleaning brush barrel 1203 contacts the contaminated part of the power facility, and the rotating insulation cleaning brush barrel 1203 is used for rotational cleaning, thereby realizing precise cleaning and maintenance operations.
