Abstract

The utility model relates to a mechanical brush head for cleaning a column type insulator, which comprises two brush discs with a polygonal shaft hole in the center. Long brush hairs are clamped between the two brush discs; the two brush discs are screwed down and fixedly arranged through bolts; brush hairs are arranged on the outer side surfaces of the two brush discs and are made of steel wires or are formed by mixing steel wires and brush hairs; and each brush disc is made of an insulating material. The mechanical brush head has the advantages that the structure is simple, the maintenance is convenient, and the specification of the mechanical brush head is completely identical with that of the existing brush head; as the brush hairs are arranged at the outer sides of the brush discs, when the umbrella edge of the column type insulator is cleaned, the brush head can thoroughly clean dirt in an inner cavity of the umbrella edge and can also clean hardened dirt; and compared with the cleaning effect of the existing mechanical brush, the cleaning effect of the mechanical brush head is greatly improved. Therefore, the mechanical brush head is an ideal upgraded product of the existing product.

Description

Clean the mechanical brush that pillar insulator is used

[technical field]

The utility model relates to a kind of mechanical brush that is used to clean pillar insulator.

[background technology]

High-tension insulator is the electric elements that are used for the tenaculum electric conductor and make its insulation, is generally clamped with adhesive gummed or machinery by insulating part (like porcelain spare) and metal-ware (like steel pin, chapeau de fer, flange etc.) to form.Insulator is used very wide in power system, generally belongs to external insulation, under atmospheric conditions, works.The external belt electric conductor of the bus of overhead transmission line, power plant and electric substation and various electrical equipments must be used the insulator support, and makes it and the earth (or ground connection thing) or other have the conductor insulation of potential difference.

The disruptive discharge that takes place along insulating surface is called flashover, and flashover property is the main electric property of insulator.For avoiding the puncture that is in operation, the breakdown voltage of insulator is higher than flashover voltage.Because insulating part exposes for a long time in the atmosphere of filth, its surface has built up dirt, and these dirts contain salt, acid, alkaline components; Generally all water-soluble; The water-soluble back of dirt electrolyte, electric conductivity is strong, and the flashover voltage when the dirt insulator makes moist is significantly less than its dried, wet flash-over voltage; Leakage current is increased, thereby cause insulator arc-over.Because the successful reclosing rate after the pollution flashover tripping operation is very low, the pollution flashover of insulator develops into large tracts of land, long pernicious power outage easily.The pollution flashover of high-voltage transmission line insulator string is one of key factor that influences operation of power networks, and along with the aggravation of power system development and all kinds of pollutions, the dirt flashover fault is serious day by day, and it seriously hampers safe, stable, the economical operation of power system.

The existing conventional means that solves pollution flashover is that the insulator dirt is cleaned; But the cleaning performance of existing cleaning brush araeosystyle insulator is unsatisfactory; Reason is that existing insulator surface has long following rib, is used to realize bigger creep age distance, has often gathered a large amount of dirts under its umbrella in the rib inner chamber; All adopt the edge to have the disc brush (shown in accompanying drawing 1) of bristle and clean brush, the upper and lower surfaces of rib inner chamber can't clean up under the umbrella.

[utility model content]

The utility model technical problem to be solved is to provide a kind of mechanical brush that is used to clean pillar insulator, can remove the dirt in the rib inner chamber under the pillar insulator umbrella comprehensively.

The technical scheme of the utility model is: clean the mechanical brush that pillar insulator is used, comprise that two centers have the brush dish of polygonal shaft hole, accompany bristle between said two brush dishes, this bristle is symmetrically distributed along said axis hole center; Tighten fixingly between said two brush dishes through bolt, said two brush dish lateral surfaces are provided with bristle.

As the further improvement of such scheme, said two brush dishes are processed by insulating materials, and its effect is to prevent that operating personnel from getting an electric shock.

Another kind as such scheme improves, and said bristle is mixed and made into by steel wire or by steel wire, bristle, its objective is to disposing the dirt of insulator surface sclerosis better, reaches superior cleaning.

The advantage of the utility model is: this product structure is simple, and is easy to maintenance, and specification and existing brush are identical; Owing to be employed in brush dish arranged outside bristle; During rib, brush can all clean up the dirt in the rib inner chamber under the umbrella, and can fall the dirt removal that has hardened under cleaning the pillar insulator umbrella; Cleaning performance is brushed with significantly than existing machinery and improves, and is the desirable upgrading products of existing product.

[description of drawings]

Combine embodiment that the utility model is done further to describe with reference to the accompanying drawings.

Fig. 1 is the structural representation of existing machinery brush,

Fig. 2 is the structural representation of the utility model,

Fig. 3 is the vertical view of the utility model brush dish.

[specific embodiment]

Referring to accompanying

drawing

2,3, clean the mechanical brush that pillar insulator is used, comprise that two centers have the brush dish 1 of polygonal shaft hole 3, polygonal shaft hole 3 is used for cooperating with motor transmission shaft.Accompany long brush hairs 2 between two brush dishes 1, long brush hairs 2 is symmetrically distributed along axis hole 3 centers, tightens fixingly between two brush dishes 1 through bolt, and two brushes coil 1 lateral surface and are provided with the bristle 4 that coils 1 approximate vertical with brush.

Two brushes coil 1 profile and can be made into circle or regular polygon, are processed by insulating materials such as bakelite or plastics, and its effect is to prevent that operating personnel from getting an electric shock.Along axis hole 3 a plurality of bristles hole is set at its lateral surface when making bakelite brush dish, bristle 4 is installed in the bristle hole.If the plastic bruss dish, directly one-shot forming when brush dish extrusion molding of bristle 4.

Bristle 4 is mixed and made into by steel wire or by steel wire and bristle, its objective is that general bristle quality is softer in order can dispose the dirt of the dry and hard sclerosis of insulator surface apace, is difficult to remove clean to this sclerosis dirt.

Although illustrated and described the embodiment of the utility model; For those of ordinary skill in the art; Be appreciated that under the situation of principle that does not break away from the utility model and spirit and can carry out multiple variation, modification, replacement and modification to these embodiment, the scope of the utility model is limited accompanying claims and equivalent thereof.
