Auxiliary flashover preventing device for electric power line

Abstract

The invention discloses an auxiliary flashover preventing device for an electric power line. The auxiliary flashover preventing device for the electric power line comprises a sweeping head which is driven by a power device through a transmission hose. The sweeping head comprises a rotating brush which is arranged vertically. One side of the rotating brush is covered with a protection cover with a C-shaped cross section. A handle is fixedly arranged on the outer side of the protection cover. An upper rod which extends transversely is fixedly arranged at the upper end of the inner side of the protection cover. The end of the upper rod is in running fit with the upper end of the rotating brush through an upper connecting device. A lower rod which can swing up and down is hinged to the lower end of the inner side of the protection cover through a horizontal shaft and is in running fit with the lower end of the rotating brush through a lower connecting device. The auxiliary flashover preventing device for the electric power line has the advantages that the structure is reasonable, a scrubbing task can be completed rapidly according to the shape of scrubbed equipment, a short-distance scrubbing mode and a long-distance scrubbing mode can be switched freely and rapidly without changing the position of an operator, the scrubbing angle can be adjusted freely, stubborn stains can be scrubbed away, and scrubbing dead angles are avoided; time and labor are saved, scrubbing personnel can be well protected and can be prevented from inhaling dust and being stained by dust, and the situation that dirt enters the eyes of the scrubbing personnel is also avoided; and wiped-off dust pollutants are prevented from falling onto equipment below, limitation by the scrubbing height is avoided, the scrubbing task can be completed by one person independently, and the scrubbing effect is good.

Description

technical field [0001] The invention relates to an anti-flashover auxiliary device for power lines. Background technique [0002] At present, cleaning and decontamination of power equipment in the power system is a very heavy and repetitive work, and it also has certain harm to the health of the staff. Before the arrival of spring and autumn every year, rain and fog increase. In order to prevent flashover accidents caused by dirt and dust on power equipment, the porcelain parts (mainly insulators) of power equipment need to be dust-removed and cleaned, and then painted. Anti-fouling flashover coating, this work requires a lot of manual work, and the staff wipes it bit by bit with a rag in their hands. The workload is very heavy and the intensity of fatigue is very high.

Problems solved by technology

Before the arrival of spring and autumn every year, rain and fog increase. In order to prevent flashover accidents caused by dirt and dust on power equipment, the porcelain parts (mainly insulators) of power equipment need to be dust-removed and cleaned, and then painted. Anti-fouling flash paint, this work requires a lot of manual work, and the staff wipes it bit by bit with a rag in their hands. The workload is very heavy and the intensity of fatigue is very high.

Moreover, it is inconvenient for the staff to stand and move when cleaning on the equipment, so they can only work with one hand, and the other hand must hold the porcelain column to ensure personal safety and prevent falling from high altitudes. If you can touch the equipment at close range, you will inhale a large amount of dust at the same time, which will also cause considerable damage to your health.

[0003] At present, there is a device on the market that uses the extension rod to lift the rag into the air to scrub the power system equipment, which can solve the problem of dust inhalation or contamination due to the traditional scrubbing method being too close to the power system equipment, and has a better protective effect. , to ensure the health of the operator, but this scrubbing equipment also has the following disadvantages: 1, because the rag is lifted into the air by the extension rod for scrubbing, the scrubbing strength of the rag is greatly reduced, resulting in unclean scrubbing; 2. 1. The operation method of using the extension rod to lift high into the air requires the operator to continuously control the movement of the rag at the high altitude on the ground, which is very time-consuming and laborious; 3. When scrubbing, it is necessary to raise the head and continuously observe the scrubbing process, so that the scrubbed solid particles may fall into the eyes , which seriously threatens the safety of the eyes; 4. When encountering stubborn stains, it needs to be wiped off with force and soaked in water, but it is difficult for the scrubbing equipment that lifts the extension rod to achieve such a function; 5. Since the operator is operating on the ground, the position and The length of the extension rod is fixed and other factors limit, the adjustable range of the scrubbing angle is very small, and it is easy to have a dead angle of scrubbing, and it is impossible to achieve thorough scrubbing; 6. The scrubbing equipment using the extension rod is generally only suitable for scrubbing at a height of less than ten meters. Scrubbing at a height of tens of meters cannot be completed at all, so there is a problem of limited scrubbing height; 7. During scrubbing, dirt and dust will fall to a part of other equipment, dirty other equipment, and adhere to a part of the rag , so it is necessary to scrub the equipment for a while, put the extension rod down, and then clean the rag again, which is very inefficient, and generally requires an auxiliary person who cleans the rag to cooperate with the operation
