Substation live water washing robot system and method

Abstract

Disclosed are a charged water-flushing robot system and method for substation. The system comprises a main flushing robot, an auxiliary flushing robot, and a pure water preparation apparatus, wherein the main flushing robot and the auxiliary flushing robot are respectively connected to the pure water preparation apparatus via a high pressure pipeline; the main flushing robot comprises a vehicle body moving mechanism, a lifting mechanism and a water gun flushing mechanism; the vehicle body moving mechanism is connected to a revolving platform (8) of the lifting mechanism via a revolving bearing, the revolving platform (8) of the lifting mechanism is mounted with a multi-sectional multi-stage telescopic arm, the multi-sectional multi-stage telescopic arm are connected to the water gun flushing mechanism via a levelling cylinder. The device uses a robot instead of human labour to complete an insulator flushing operation in a substation to enable operators to stay within a safety region, thereby ensuring the safety of the operators, reducing labour intensity, and improving the flushing efficiency and automation level.

Description

technical field [0001] The invention relates to a system and method for a substation charged water washing robot. Background technique [0002] Substation insulators are exposed to the external environment for a long time, and dirt is easy to deposit on the surface. These dirt are prone to pollution flashover accidents when they are damaged by bad weather. The washing operation of insulators with live water can improve the reliability of power supply, reduce power failure losses, and ensure the safety of substations and transmission lines. At the present stage, the washing operation of substation insulators mainly has the following shortcomings: [0003] 1. Most of the cleaning methods are carried out by cleaning technicians who enter the site with hand-held cleaning equipment. Manual cleaning not only depends on the weather conditions, but also requires cleaning personnel to have a high technical level and skilled operation procedures. Standardized safety protection to av...

AI Technical Summary

Problems solved by technology

[0003] 1. Most of the cleaning methods are carried out by cleaning technicians who enter the site with hand-held cleaning equipment. Manual cleaning not only depends on the weather conditions, but also requires cleaning personnel to have a high technical level and skilled operation procedures. Standard safety protection to avoid safety accidents caused by short-circuit current, causing casualties. This type of operation has potential safety hazards

[0004] 2. Manual operations are faced with many problems such as high labor intensity, low efficiency, and low level of automation; the technical requirements for electrified water flushing are relatively high, and are affected by various factors such as the environment, pollution, equipment creepage, and equipment layout. Equipment flashover prone to occur during flushing

[0005] 3. Considering that the flushing operation of live water is affected by various aspects such as flushing angle and water pressure, manual operation sometimes cannot completely flush away the dirt on the outer insulating surface of the equipment

For insulators in special geographic locations, the use of a separate water washing robot also has the problem of being unable to guarantee effective washing of substation insulators in all directions. Therefore, it is necessary to cooperate with the auxiliary washing equipment and the main washing robot to achieve effective washing of all positions of the insulators. rinse

[0006] 4. The existing water washing equipment has low automation, low efficiency, high energy consumption, and great potential safety hazards

Moreover, the existing water washing equipment does not have the function of pure water preparation, and needs to be equipped with a special pure water preparation device. The equipment occupies a large area, and it cannot achieve flexible control in an environment with small space; or the pure water preparation capacity is poor. , resulting in potential safety hazards during flushing operations
