Description

wind cleaning ring

technical field

The utility model relates to a power transmission line cleaning device, in particular to a wind cleaning ring.

Background technique

In the power transmission system, due to the natural climate, the insulators of the transmission line will accumulate dirt, such as dust, snow, etc., due to these dirt, pollution flashover will occur, and pollution flashover will cause huge economic losses to the power system.

In order to remove the dirt on the insulators, the power system uses the insulator air cleaning ring to remove the dirt on the insulators. The schematic diagram of the insulator wind cleaning ring can be referred to Fig. 1, is made of an insulating ring 1 and a plurality of wind driving bowls 11 (note that the label is bolded) arranged in the same direction on the insulating ring 1, when working in the natural wind Under the effect, the cleaning ring will rotate or swing on the surface of the insulator 2, and the wind force will push the cleaning ring to rotate along the insulator, and the edges of each pushing bowl 11 on the cleaning ring will be able to continuously scrape off the dirt on the surface of the insulator under the action of friction. Dirt, so as to ensure the cleanliness of the insulator surface.

This insulator wind cleaning ring is to push the natural edge of the bowl 11 by the wind to clean dirt when it is working. Because the edge of the bowl 11 pushed by the wind is in a tangential and parallel contact relationship with the surface of the insulator 2, the wind pushes the bowl 11 on the surface of the insulator 2. The dust and dirt move on it; since the wind pushes the bowl to be 11 round, the contact surface with the insulator 2 is point contact, and the contact surface is very small. When the wind pushes, the force to scrape off the dust and dirt is very small, thus affecting The cleaning quality of the cleaning ring cannot meet the cleaning requirements of the insulator.

Utility model content

The utility model aims to provide a wind cleaning ring, which can solve the above-mentioned problem that the wind pushes the bowl to point contact with the insulator, the contact surface is small, and cannot meet the cleaning requirements of the insulator.

According to one aspect of the present invention, a wind cleaning ring is provided, comprising: each wind pushing bowl connected to the insulating ring, and the sides of the wind pushing bowls are polygonal.

Further, the number of sides of the polygon is between 4 and 8.

Further, the wind-driven bowl is composed of a circular arc bowl wall and bowl walls of various planes.

Furthermore, there are angled or curved protrusions on the edge of the bowl.

Further, the angle of the protrusion is any angle between 30 degrees and 60 degrees.

Further, the angle of the protrusion is 45 degrees.

Further, the connection between the insulating ring and the wind-driven bowl includes: the insulating ring passes through the perforation of the wind-driven bowl, and the two sides of the perforated hole of the wind-driven bowl respectively have buckles integrally connected with the insulating ring, and two opposite buckles Hold the wind to push the perforated sides of the bowl.

The wind-driven bowl in the utility model can effectively increase the contact area with the insulator due to the use of the polygonal bowl edge. Dust and dirt on the surface of the insulator can be removed. Compared with the circular wind-driven bowl, since the contact between the edge of the bowl and the insulator changes from point contact to line contact, the cleanliness of the insulator is greatly improved.

Detailed ways

The utility model will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

The wind force pushes the bowl in the wind force cleaning ring in the utility model, and its mouth adopts polygon, and the number of sides is preferably between 4 to 8. In the present embodiment, the wind force pushes the bowl to adopt a hexagonal shape. After probation, the hexagonal shape The wind push bowl cleans the outer surface of the insulator best. For its schematic diagram, refer to the schematic diagrams shown in FIG. 2 , FIG. 3 and FIG. 4 .

Fig. 2 shows the front view of the bowl pushed by the wind, Fig. 3 shows the left side view of the bowl pushed by the wind, Fig. 4 shows the sectional view of Fig. 2, the bowl wall of the bowl pushed by the wind is composed of a plane part 22 and an arc part 23 The bottom is perforated 24, and there are angled or curved protrusions 21 on the edge of the bowl driven by the wind, which are used to remove stains on the insulator through the protrusions when the cleaning ring is driven by the wind to rotate. In this embodiment, angled protrusions 21 are used, and the angle of the protrusions 21 can be between 30 degrees and 60 degrees, preferably 45 degrees, so as to shorten the rainwater residence time. If the wind pushes the bowl and does not set the protrusion 21, it can also play a certain cleaning effect.

Referring to the connection schematic diagram shown in Figure 5, each wind-driven bowl is fixed on the insulating ring 25 through the perforation 24 at the bottom of the bowl, and an even number of buckles 26 are fixed on the insulating ring 25, and the buckles 26 are opposite to each other to push the wind force. The bowl is clamped on the insulating ring 25 to realize fixed clamping or movable clamping. If it is fixedly clamped, each wind-forced bowl cannot rotate, and the straight parts of each bowl edge are on the same plane; Refer to FIG. 6 for a schematic diagram of connecting various wind-driven bowls on the insulating ring 25 .

After the cleaning ring is installed on the insulator 2, you can refer to the schematic diagram shown in Figure 6, because the wind force pushes the bowl to adopt a polygonal shape, and the straight line portion of the bowl edge and the plane contact surface of the insulator 2 are larger. When working, under the wind force, the wind force pushes the protrusion 21 on the edge of the bowl to rotate on the upper surface of the insulator 2, scraping the dust and dirt on the surface of the insulator 2 to achieve dust removal and decontamination, which can better remove The effect of dirt on the insulator can more effectively improve the cleaning effect of the cleaning ring.

The wind force cleaning ring in the utility model can effectively increase the contact area with the insulator due to the use of the polygonal bowl edge. Dust and dirt on the surface of the insulator can be removed. Compared with the circular wind-driven bowl, since the contact between the edge of the bowl and the insulator changes from point contact to line contact, the cleanliness of the insulator is greatly improved.

The above are only preferred embodiments of the utility model, and are not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
