Description

Technical Field

[0001] The utility model relates to the technical field of power transmission line inspection, in particular to an autonomous obstacle-crossing power transmission line inspection device. Background Art

[0002] Transmission lines refer to power lines that transmit electric energy from power plants to power load centers and communicate between power systems. Among them, transmission lines that use poles and insulating materials to raise the conductors off the ground are overhead transmission lines. Transmission lines are outdoors for a long time. Some line corridors need to pass through various complex geographical environments, such as passing through large reservoirs, lakes or mountains. Due to environmental or human influences, certain defects will appear on the surface of the transmission lines. Therefore, it is necessary to regularly inspect the surface of the transmission lines, and repair the defects after detection, so as to ensure the long-term normal operation of the transmission lines.

[0003] In order to inspect transmission lines for defects, small drones are usually used to walk along the transmission lines to conduct inspections along the way. During use, the entire inspection device is first set up on the transmission line by the drone, and then the walking wheels are driven to walk along the transmission line to conduct inspections for defects along the line. However, since the transmission lines pass through complex geographical environments such as large-scale reservoirs, lakes or mountains, obstacles such as mud or other lumps may adhere to the surface of the transmission lines. Since the walking wheels often do not have an obstacle clearing function, the entire inspection device cannot move further when encountering obstacles, and further inspections must be carried out after the obstacles are cleared, thereby reducing the overall inspection efficiency.

[0004] Therefore, it is necessary to invent an autonomous obstacle-crossing transmission line inspection device to solve the above problems. Utility Model Content

[0005] In order to address the deficiencies of the prior art, the purpose of the utility model is to provide an autonomous obstacle-crossing transmission line inspection device, which solves the problem in the prior art that, because the transmission lines pass through complex geographical environments such as large-scale reservoirs, lakes or mountains, obstacles such as mud or other lumps may adhere to the surface of the transmission wires, and because the walking wheels often do not have an obstacle-clearing function, the entire inspection device cannot move further in line with the obstacles when encountering them, and needs to clear the obstacles before it can move forward for inspection, thereby reducing the overall inspection efficiency.

[0006] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0007] An autonomous obstacle-crossing transmission line inspection device comprises a U-shaped traveling frame capable of traveling along a transmission line, a bottom surface of a side branch of the U-shaped traveling frame being located at an upper part being provided with a plurality of telescopic components with controllable sliding distances for sliding along its traveling direction, and the lateral sliding of each of the telescopic components does not interfere with each other, the telescopic components can autonomously be lifted and lowered longitudinally, a mounting plate is detachably connected to the bottom end of the telescopic component, a traveling wheel capable of rotatably abutting against a transmission line is rotatably provided below the bottom surface of the mounting plate, inspection components capable of video recording the transmission line are provided on the left and right side walls of each of the mounting plates, and obstacle monitoring components capable of monitoring obstacles on the transmission line are provided on the left and right side walls of a side branch of the U-shaped traveling frame being located at an upper part.

[0010] As a preferred solution of the utility model, one side of the bottom surface of the mounting plate is detachably connected to a mounting seat, and the other side of the bottom surface of the mounting plate is connected to a bracket. A rotating part is detachably installed in the mounting seat, and a rotating rod is rotatably provided on the side of the rotating part close to the bracket. The walking wheel is detachably mounted on the rotating rod, and one end of the rotating rod located outside the walking wheel is rotatably connected to the bottom end of the bracket.

[0011] As a preferred solution of the utility model, an arc-shaped groove is formed on the outer peripheral side wall of each of the traveling wheels, and a plurality of anti-slip arc strips are connected to the surface of the arc-shaped groove.

[0012] As a preferred solution of the utility model, the four corners of the upper side branch of the U-shaped walking frame can be detachably installed with flying components, and the bottom surface of the lower side branch of the U-shaped walking frame can be detachably installed with multiple power storage components.

[0013] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0014] In the utility model, the two inspection parts on the left and right sides of each mounting plate perform defect inspection on the transmission line. When the walking wheel moves along the transmission line from left to right, the obstacle monitoring part located on the right side of the U-shaped walking frame monitors and warns the obstacle at the front end of the transmission line.

In the utility model, without the need for additional obstacle clearing devices to clear obstacles on the transmission line, obstacle avoidance is completed by the three traveling wheels passing over obstacles in turn, and autonomous obstacle crossing is achieved without affecting the continuity of the inspection, thereby improving the overall inspection efficiency.

[0022] The top of each telescopic component 7 is detachably connected to an upper connecting plate 6, the top of the upper connecting plate 6 is connected to a slide 3, and the bottom surface of a side branch of the U-shaped walking frame 1 located at the top is installed with a guide rail 2 along its walking direction. The slide 3 is slidably connected to the guide rail 2, and the sliding of the slide 3 along the guide rail 2 is electrically controlled, so that the sliding of the slide 3 is intelligent.

[0023] The bottom end of each telescopic component 7 is detachably connected to a lower connecting plate 8, a mounting plate 9 is mounted on the bottom surface of the lower connecting plate 8, side connecting plates 16 are mounted on the left and right side walls of the mounting plate 9, and an inspection piece 17 is detachably mounted below the side connecting plate 16.

The three traveling wheels 12 completely pass over the obstacle, that is, the entire inspection device completely passes over the obstacle on the transmission line; when the traveling wheels 12 travel along the transmission line from right to left, the obstacle monitoring component 18 located on the left side of the U-shaped traveling frame 1 monitors and warns of obstacles at the front end of the transmission line.
