360-degree variable diameter pneumatic cleaning purger

Abstract

The invention discloses a 360-degree variable diameter pneumatic cleaning purifier for cleaning pillar insulators. It includes a fixed frame, left and right movable mechanical arms, left and right cylinders, left and right cylinder stroke controllers, horizontal anglers, vertical anglers and Four pneumatic purge sweep brushes. The two ends of the fixed frame are hinged to connect the movable mechanical arms. There are separate cylinders on the outside of both ends of the fixed frame. The left and right cylinder stroke controllers are respectively placed on the left and right cylinders or on the fixed frame. The outside of the symmetry axis of the fixed frame is connected to a horizontal angle device. The horizontal angle device Connected to the vertical cornerer, four pneumatic purging brushes are placed on the fixed frame and the movable robotic arm. The above-mentioned cleaning and purging device is installed on an insulating rod or an insulating lifting mechanism by a vertical angle device. This cleaning and purging device can perform 360-degree rotational cleaning and synchronous purging of insulators, and can instantly change the cleaning diameter. It can perform 360-degree cleaning and purging of insulators of different diameters or special-shaped insulators with uneven thickness, without cleaning dead corners; this cleaning device The purge is a high-strength insulating product, suitable for high and low voltage live and non-live operations of various voltage levels.

Description

technical field [0001] The invention relates to a pneumatic cleaning machine for cleaning post insulators, in particular to a variable-diameter pneumatic cleaning purger capable of cleaning insulators with different diameters at 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. When these pollutants are wetted by heavy fog and light rain, they will form electrolytes and destroy insulation, 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. ...

AI Technical Summary

Problems solved by technology

The widely used anti-pollution flashover technology for external insulation of power equipment is to adjust the creepage distance, surface brushing and manual cleaning. 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
