Description

Technical Field

[0001] The utility model belongs to the technical field of power transmission line facilities, and in particular relates to a foreign matter cleaning device for a power transmission line. Background Art

[0002] The transmission line is realized by using a transformer to step up the voltage of the electric energy generated by the generator, and then connecting it to the transmission line through control equipment such as circuit breakers. Transmission lines are divided into overhead transmission lines and cable lines. Overhead transmission lines are composed of line towers, conductors, insulators, line hardware, guy wires, tower foundations, grounding devices, etc., and are erected above the ground. According to the nature of the transmitted current, transmission is divided into AC transmission and DC transmission.

[0003] As a commodity, electricity has become a necessity for production and life in thousands of households. Transmission lines have been running in the natural environment for a long time and are prone to entanglement with foreign objects. For example, foreign objects such as agricultural greenhouse plastics, shade nets, woven belts, advertising cloth, kites and kite ropes are entangled in power transmission lines due to wind and other reasons. After being exposed to rain or moisture, these foreign objects have poor insulation properties and are prone to cause transmission line tripping, short circuit and other accidents, seriously affecting the safety of power supply to the power grid. Therefore, it is necessary to regularly clean up foreign objects on the transmission lines to prevent harmful situations. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a transmission line foreign matter cleaning device, which can clean the foreign matter on the transmission line and ensure the safety of electricity use.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A power transmission line foreign matter cleaning device comprises a base, the bottom of the base is provided with four casters, the top of the base is provided with a telescopic component, the top of the telescopic component is fixedly connected with a mounting plate, and the top of the mounting plate is provided with a cleaning component;

[0007] The telescopic assembly includes a first servo motor, an "X"-shaped telescopic frame and a lifting bar, wherein the first servo motor is arranged inside the base, and a bidirectional threaded rod is fixedly connected to the output end of the first servo motor, and the bidirectional threaded rod is rotatably connected to the two inner walls of the base;

[0008] The two ends of the bidirectional threaded rod are threadedly connected to two moving blocks, a movable groove is provided at the top of the base corresponding to the bidirectional threaded rod, the upper parts of the two moving blocks pass through the movable groove and are fixedly connected with a movable shaft, the direction of the movable shaft is horizontally perpendicular to the bidirectional threaded rod, and an "X"-shaped telescopic frame is hingedly connected above the two movable shafts;

[0009] The telescopic frame is provided with a plurality of parallel lifting bars at equal intervals from bottom to top, each lifting bar is provided with a slide groove matching the movable shaft in the middle, the movable shaft runs through the slide groove, and anti-dropping sheets are fixedly provided at both ends of each movable shaft.

[0010] Through the above technical solution, the two moving blocks can be driven to move closer or farther from each other by rotating the threaded rod, thereby finally achieving the extension or shortening of the telescopic rod and extending the cleaning assembly to the height of the power transmission line. Both ends of the movable shaft pass through the slide groove, and the movable shaft forms an anti-slip structure through the anti-slip sheet, so that the movable shaft can move along the slide groove while the anti-slip sheet can prevent the movable shaft from detaching from the slide groove, thereby ensuring the normal operation of the telescopic assembly.

[0011] Furthermore, a limiting rod slidably connected to the moving blocks is provided through the bottom ends of the two moving blocks, the limiting rod is parallel to the bidirectional threaded rod and both ends of the limiting rod are respectively fixedly connected to the two inner walls of the base.

[0012] Furthermore, the cleaning assembly includes two cylinders fixedly connected to the inner side walls of the mounting plate, the other ends of the two cylinders are fixedly connected to push blocks, the top of each push block is provided with a support rod, the top of each support rod is connected to a bearing seat, the top of each bearing seat is fixedly connected to a cleaning wheel, a second servo motor is provided inside the top wall of the cleaning wheel, and the output end of the second servo motor is fixedly connected to a cleaning blade.

[0013] Through the above technical solution, after the cleaning component is sent to a high place by the lifting component, the cylinder is used to push the two cleaning wheels to clamp the power line in the middle, and the second servo motor drives the cleaning blade to rotate to cut foreign matter on the power line. This structure can remove foreign matter without manual approach to the power line, avoiding close contact between workers and power lines and reducing safety hazards.

[0014] Furthermore, each of the cleaning wheels is symmetrically distributed about the center line of the mounting plate. The two opposite sides of each of the cleaning wheels are both arc-shaped concave structures.

[0015] Through the above technical solution, the two cleaning wheels can better fit the outside of the wires, clamping the transmission line in the middle, and the cleaning wheels can rotate through the bearing seat at the bottom when removing foreign matter along the transmission line, reducing the wear of the cleaning wheels on the wires.

[0016] Furthermore, the two cleaning blades are staggered in height direction.

[0017] The above technical solution can avoid safety accidents caused by contact and chipping between cleaning blades when removing foreign objects wrapped around electric wires.

[0018] Compared with the prior art, the power transmission line foreign matter cleaning device of the utility model has the following beneficial effects:

[0019] (1) The first servo motor, the threaded rods on both sides, the moving block and the movable shaft cooperate with each other to drive the bottom ends of the telescopic rods to move closer to each other, so that each layer of the lifting strip can be raised and lowered, and the mounting plate pushes the cleaning component to the height of the wire to remove foreign objects. There is no need for manual climbing to a high place for cleaning, which reduces the workload of workers and also reduces the risk of injury to workers.

[0020] (2) The cleaning component is set up, using a cylinder to push two cleaning wheels to clamp the power line in the middle, and the second servo motor drives the cleaning blade to rotate to cut foreign matter on the power line, thereby avoiding close contact between workers and the power line and reducing safety hazards.
