360-degree variable diameter pneumatic cleaning purger

Abstract

The invention discloses a 360-degree reducing pneumatic cleaning blower used for cleaning a supporting insulator. The 360-degree reducing pneumatic cleaning blower comprises a fixed machine frame, a left movable mechanical arm, a right movable mechanical arm, a left air cylinder, a right air cylinder, a left air cylinder stroke controller, a right air cylinder stroke controller, a horizontal angling device, a vertical angling device and four pneumatic blowing and cleaning brushes. Hinges at the two ends of the fixed machine frame are connected with the movable mechanical arms, the outer sides of the two ends of the fixed machine frame are provided with the air cylinders, the left air cylinder stroke controller and the right air cylinder stroke controller are arranged on the left air cylinder and the right air cylinder respectively or the fixed machine frame, the outer side of the symmetry axis of the fixed machine frame is connected with the horizontal angling device connected with the vertical angling device, and the four pneumatic blowing and cleaning brushes are placed on the fixed machine frame and the movable mechanical arms. The cleaning blower is integrally installed on an insulating rod or an insulating lifting mechanism through the vertical angling device. The cleaning blower can carry out 360-degree rotation cleaning and synchronous blowing on the insulator, the cleaning diameter can be changed immediately, 360-degree cleaning and blowing on insulators with different diameters and special-shaped insulators with different thicknesses are achieved, and no dead angle of cleaning exists. The cleaning blower is a high-intensity insulating product, and suitable for high and low voltage hot-line work and non-hot-line work with various voltage classes.

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
