A high-pressure water spray system for electric water washing robots in substations

Abstract

The invention provides a high-pressure water spray system for an electrification water washing robot of a transformer substation. The high-pressure water spray system is connected with the electrification water washing robot through a high-pressure pipe; the high-pressure water spray system is characterized in that an electromagnetic clutch is connected with a power takeoff arranged on an automotive chassis, and is connected with a high-pressure water pump through a power transmission device; and a pressure detection device is installed at the output end of the high-pressure water pump, and a water resistor is installed at the tail end of a water outlet pipe. The high-pressure water spray system has the beneficial effects that the output end of the high-pressure water spray system is connected with the electrification water washing robot, and the electrification water washing robot can be connected with an own pure water preparing device through the high-pressure water spray system; and under the condition that a pure water source exists, the electrification water washing robot can be directly connected with the pure water source through the high-pressure water spray system, the system maneuverability is high, and the cost is saved to a certain degree.

Description

technical field [0001] The invention relates to the field of substation live water washing robots, in particular to a high-pressure water spray system used for substation live water washing robots. 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. [0003] In the water flushing process, water purity and pressure are two key indicators. In particular, the conductivity of pure water is the most important factor affecting the flushing of charged water. If the conductivity does not meet the standard, it will cause great harm to equipment and personal safety. [0004] The current substation insulator fl...

AI Technical Summary

Problems solved by technology

[0005] 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 avoid safety accidents caused by short-circuit current, causing casualties. This type of operation method has potential safety hazards;

[0006] 2. The technical requirements for electrified water flushing are relatively high. Affected by various factors such as the environment, pollution accumulation, equipment creepage, and equipment layout, equipment flashover is prone to occur during manual flushing. At the same time, it is faced with high labor intensity, low efficiency, and automation. Low level and many other problems; Considering that the live water flushing operation is affected by various aspects such as flushing angle and water pressure, manual operations sometimes cannot completely flush away the dirt on the outer insulating surface of the equipment

[0007] 3. The existing water washing equipment has low automation, low efficiency, high energy consumption, and great potential safety hazards

Moreover, when the existing water washing equipment is used for water washing operations, it needs to be connected with a special pure water preparation device. In this way, when the site has a pure water source, the flexible replacement of the water intake method cannot be realized, which is likely to cause waste of resources. Able to freely fetch water according to the actual situation on site
