Abstract

The utility model provides a wind clean ring, which comprises various wind push bowls which are connected on an insulating ring, wherein the bowl sides of the wind push bowls are polygons, the side number of the polygons is between 4 and 8, the bowl sides are further provided with angle or radian bulges, the angles of the bulges are any one of between 30 degrees and 60 degrees, the insulating ring penetrates through holes of the wind push bowls, the two sides of the through holes of the wind push bowls are respectively provided with buckles which are integrally connected with the insulating ring, and the two buckles which are relative clamp the two sides of the through holes of the wind push bowls. Because the wind push bowls use polygonal bowl sides, the contact area with insulators can be effectively increased, when the wind push bowls drive the clean ring to rotate along the planes of the insulators under the action of wind, the bulges on the bowl sides can remove dust and fouling on the surfaces of the insulators, thereby greatly increasing the clean degree of the insulators.

Description

The wind-force wiper ring

Technical field

The utility model relates to the transmission line cleaning device, more specifically, relates to a kind of wind-force wiper ring.

Background technology

In the electrical power transmission system, the insulator of transmission line is because natural climate can accumulate dirt, and as travel fatigue, accumulated snow etc., because these dirts cause the pollution flashover phenomenon to take place, the pollution flashover phenomenon can cause the tremendous economic loss to electric power system.

In order to remove the dirt on the insulator, the dirt on the insulator wind-force wiper ring removal insulator is used in electric power system.The schematic diagram of insulator wind-force wiper ring can be referring to Fig. 1, be by a dead ring 1 and be through a plurality of wind-force of arranging by same direction on the dead ring and promote bowl 11 (noting label overstrikings) _ to constitute, this wiper ring will be in insulator 2 surface rotation or swings under natural wind action during work, wind-force promotes wiper ring and rotates along insulator, on the wiper ring each promotes the edge of bowl 11, under the effect of frictional force, just can constantly scrape off the dirt on the insulator surface, thereby guarantee the cleaning of insulator surface.

This insulator wind-force wiper ring is the natural edge cleaning dirt that promotes bowl 11 by wind-force when work, because it is tangent and parallel contact relations with insulator 2 surfaces that wind-force promotes the edge of bowl 11, wind-force promotes bowls 11 at the dust on insulator 2 surfaces with move above the dirt; Because it is 11 circles that wind-force promotes bowl, therefore contact for point with the contact-making surface of insulator 2, contact-making surface is very little, when wind-force promotes, so it is very small to strike off the strength of dust and dirt, thereby has influenced the cleaning quality of wiper ring, can not satisfy the requirement of removing contamination of insulator.

The utility model content

The utility model aims to provide a kind of wind-force wiper ring, can solve above-mentioned wind-force promotion bowl and contact with insulator point, and contact-making surface is less, can not satisfy the problem of removing contamination and requiring of insulator.

According to an aspect of the present utility model, a kind of wind-force wiper ring is provided, comprising: comprise that each wind-force that is connected on the dead ring promotes bowl, the bowl limit that wind-force promotes bowl is a polygon.

Further, polygonal limit number is between 4 to 8.

Further, wind-force promotion bowl is made up of the bowl wall of a circular arc and the bowl wall on each plane.

Further, the projection that also has angle or radian on the bowl limit.

Further, the unspecified angle of Tu Qi angle between 30 degree and 60 degree.

Further, Tu Qi angle is 45 degree.

Further, the connection that dead ring and wind-force promote between the bowl comprises: dead ring passes the perforation that wind-force promotes bowl, the perforation both sides that wind-force promotes bowl have the buckle that is connected with the dead ring one respectively, and two relative buckles hold the perforation both sides that wind-force promotes bowl.

Wind-force in the utility model promotes bowl, owing to adopt polygonal bowl limit, can effectively increase the contact area with insulator, when wind-force promoted bowl and driving wiper ring under the wind-force effect and rotate on the plane of insulator, the projection on the bowl limit can be removed the dust and the dirt of insulator surface.Promote bowl with circular wind-force and compare, because the bowl limit has become the line contact with contacting by a contact of insulator, the bigger cleannes that improve insulator.

Embodiment

Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.

Wind-force in the wind-force wiper ring in the utility model promotes bowl, and its rim of a bowl adopts polygon, between the limit number preferred 4 to 8, in the present embodiment, wind-force promotes bowl and adopts 6 limit shapes, and through on probation, it is best to the cleannes of the outer surface of insulator that the wind-force of 6 limit shapes promotes bowl.Its schematic diagram can be referring to Fig. 2, Fig. 3 and schematic diagram illustrated in fig. 4.

Fig. 2 shows the front view that wind-force promotes bowl, Fig. 3 shows the left view that wind-force promotes bowl, Fig. 4 shows the cutaway view of Fig. 2, constitute by planar section 22 and circular arc portion 23 on the bowl wall of wind-force promotion bowl, the bottom is perforation 24, the projection 21 that has angle or radian on the bowl limit of wind-force promotion bowl is used for when wind-force promotes the wiper ring rotation, by the spot on the projection removal insulator.In the present embodiment, adopt the projection 21 of angle, the angle of projection 21 can be between 30 degree or 60 degree, and preferred 45 degree are to shorten the rainwater time of staying.If wind-force promotes bowl projection 21 is not set, also can play certain cleaning effect.

Referring to connection diagram illustrated in fig. 5, each wind-force promotes bowl perforation 24 by bowl bottom and is fixed on the dead ring 25, fixedly have even number buckle 26 on the dead ring 25, and buckle 26 is relative in twos, wind-force is promoted bowl be stuck on the dead ring 25, realization fixedly holds or activity holds.If fixedly hold, then each wind-force promote that bowl all can't rotate and the line part on each bowl limit all on same plane; If activity holds, then each wind-force promotion bowl can rotate along dead ring 25.The schematic diagram that connects each wind-force promotion bowl on the dead ring 25 can be referring to Fig. 6.

After being installed to wiper ring on the insulator 2, can adopt polygon because wind-force promotes bowl referring to schematic diagram illustrated in fig. 6, the flat contact surface of the line part on its bowl limit and insulator 2 is bigger.During work, under wind-force promotes, projection 21 on the bowl limit of wind-force promotion bowl is rotated on insulator 2 upper surfaces, scrape the dust and the dirt on insulator 2 surfaces, realize dedusting and decontamination, can play the effect of removing dirt on the insulator better, cleaning effect that can more effective raising wiper ring.

Wind-force wiper ring in the utility model, owing to adopt polygonal bowl limit, can effectively increase the contact area with insulator, when wind-force promoted bowl and driving wiper ring under the wind-force effect and rotate on the plane of insulator, the projection on the bowl limit can be removed the dust and the dirt of insulator surface.Promote bowl with circular wind-force and compare, because the bowl limit has become the line contact with contacting by a contact of insulator, the bigger cleannes that improve insulator.

Be preferred embodiment of the present utility model only below, be not limited to the utility model, for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
