Description

Technical Field

[0001] The present invention relates to the technical field of electrical equipment maintenance, and in particular to an insulator string cleaning device based on a drone. Background Art

[0002] With the development of my country's industry, the rapid increase in the transportation mileage of electrified railways, and the continuous increase in residents' electricity consumption, the capacity and voltage of the power supply network have also been increasing accordingly, which requires the power supply system to have higher safety and operational stability. In the power supply system, high-voltage insulators are an important component, and their maintenance status is very important to the safe operation of the line. Due to long-term exposure to the environment, a layer of conductive dirt will form on its surface, which will cause flashover and other accidents, posing a great threat to the normal operation of the power grid.

[0003] The Chinese patent with application number CN202111247086.4 discloses a flushing device for a high-altitude live insulator string, which flies a drone with a main cleaning mechanism to the vicinity of the insulator string to be cleaned, collects video information through the camera on the drone, and transmits it to the display so that the staff can obtain the position of the main cleaning mechanism. The staff turns on the motor-driven water pump in the main cleaning mechanism to spray the water in the distilled water tank from the water spray pipe to clean the insulator string. However, in the above technical scheme, only the water spraying method is used to flush the insulator string, which has a weak cleaning effect on the insulator string, and the water spray pipe can only flush a certain area on the side of the insulator string facing the main cleaning mechanism at a time. If the insulator string is to be cleaned 360 degrees, the direction of the drone needs to be adjusted multiple times, thereby adjusting the water spraying direction of the water spray pipe, and even the drone needs to rotate 180 degrees around the insulator string to clean the back of the insulator string, resulting in low cleaning efficiency of the insulator string.

The sliding seat 441 is arranged in the slide groove 460, and the dual-axis motor is vertically arranged in the sliding seat 441, and its two output shafts respectively pass through the upper and lower ends of the sliding seat 441 and are connected to the driving wheel 442. The driven wheel 443 is rotatably arranged at the upper and lower ends of the sliding seat 441, and the central axis of the driven wheel 443 is parallel to the central axis of the driving wheel 442. The universal ball 444 is rotatably arranged on the sliding seat 441.

It should be noted that the first brush base 445 and the second brush base 446 are at a certain distance from the upper and lower end surfaces of the first arc-shaped clamp 420, so that the cleaning component 440 will not collide with the nozzle 450 when moving.

[0043] Among them, by setting the clamping support part 800, when the device cleans the insulator string, the insulator string can be clamped by the electric clamp 840. At this time, the rotor of the drone body 100 can be stopped appropriately, and the drone body 100 can be stopped on the clamping support part 800. In order to improve the carrying capacity of the clamping support part 800, the first adjustment cylinder 810, the second adjustment cylinder and the electric clamp 840 are all made of high-strength carbon fiber material, and their exteriors are coated with insulating coatings. Preferably, an insulating rubber 841 is also provided in the electric clamp 840 to increase the friction between the electric clamp 840 and the insulator string. A pressure sensor is provided in the insulating rubber 841, and the pressure sensor is electrically connected to the control system. The clamping force of the electric clamp 840 on the insulator string is collected in real time through the pressure sensor. Specifically, the electric clamp 840 is preferably clamped on the interval between two adjacent insulators of the insulator string. The number of the limiting slide groove and the limiting convex strip 821 are both four. The four limiting slide grooves are evenly distributed on the two vertical inner side walls of the first adjusting cylinder 810, and the four limiting convex strips 821 are evenly distributed on the two vertical side walls of the second adjusting cylinder 820. By arranging the limiting slide groove and the limiting convex strip 821, the bearing capacity of the clamping support part 800 is increased.

[0044] In summary, the drone-based insulator string cleaning device provided by the present invention performs high-altitude cleaning operations by carrying a rotating cleaning mechanism on the drone body, and replaces manual operations with automated equipment, thereby improving the safety of operations. The cleaning device can quickly locate and clamp the insulator string, and scrub the porcelain bowl on the insulator in a circumferential cleaning manner, thereby improving the cleaning efficiency.
