360-degree diameter-changing pneumatic sweeper

Abstract

The invention discloses a 360-degree diameter-changing pneumatic sweeper for sweeping a post insulator. The 360-degree diameter-changing pneumatic sweeper comprises a fixed machine frame, a left movable mechanical arm, a right movable mechanical arm, a left cylinder, a right cylinder, a left cylinder stroke controller, a right cylinder stroke controller, a horizontal angle turning device, a vertical angle turning device and four pneumatic sweeping brushes. Hinges at two ends of the fixed machine frame are connected with the movable mechanical arms, the cylinders are arranged on the outer sides of two ends of the fixed machine frame respectively, the left cylinder stroke controller and the right cylinder stroke controller are arranged on the left cylinder and the right cylinder or the fixed machine frame respectively, the outer side of a symmetrical axis of the fixed machine frame is connected with the horizontal angle turning device, the horizontal angle turning device is connected with the vertical angle turning device, and the four pneumatic sweeping brushes are arranged on the fixed machine frame and the movable mechanical arms. The whole sweeper is installed on an insulating rod or an insulating lifting mechanism through the vertical angle turning device. The 360-degree diameter-changing pneumatic sweeper can perform 360-degree sweeping on the insulator, the sweeping diameter can be changed in real time, 360-degree sweeping can be performed on the insulators of different diameters or special insulators nonuniform in thicknesses, and sweeping blind corners are avoided; and the sweeper is a high-strength insulating product and is suitable for high and low voltage live working of various voltage grades and non-electrified working.

Description

technical field [0001] The invention relates to a pneumatic cleaning machine for cleaning post insulators, in particular to a variable-diameter pneumatic cleaning device capable of cleaning insulators with different diameters in 360 degrees. Background technique [0002] Substation insulators are the support and insulation facilities for high-voltage equipment in substations. Due to being outdoors all the year round, the surface of insulators is prone to form a dirty layer. These pollutants are wetted by heavy fog and light rain, which can easily cause pollution flashover accidents. Pollution flashover accidents can cause line tripping and power outages in light cases, and cause grid disassembly in severe cases, causing large-scale catastrophic power outages. Therefore, insulators should be cleaned and decontaminated regularly. [0003] Our country has carried out anti-pollution flashover work for more than 40 years. The widely used anti-pollution flashover maintenance tec...

AI Technical Summary

Problems solved by technology

Manual cleaning must be carried out with power outages. Even if there are alternate power outages, it will cause certain risks and hidden dangers to the stable operation of the power grid.

The insulator cleaning machines that have come out are all driven by power cords, electric drills or motors, and there are potential safety hazards in high-voltage insulation. They can only clean 1 / 3 or 1 / 4 of the outer circumference of the insulator at a time, and cannot clean the insulator 360 degrees; the cleaning The machine needs to change 3-4 working positions around the insulator on the ground, move the insulation lifting bracket and cleaning equipment 3-4 times, and perform 3-4 cleanings in different directions of the insulator to complete the 360-degree cleaning of an insulator
