Description

A kind of voltage wire ice removing device

Technical field

The utility model relates to the apparatus for examination and repair of electric power transmission line, especially a kind of voltage wire ice removing device.

Background technology

At the beginning of 2008, south China area suffers the continuous especially big snowfall of large area, high-tension line large area icing, cause high-tension line can't bear the heavy load and break, electric power facility is seriously damaged, and population suffered from disaster is up to 100,000,000 more than, and direct economic loss exceedes 1,100 hundred million yuan, this precipitate ice and snow disaster has brought very big destruction to Chinese the earth transmission line, and therefore deicing of high-voltage wires problem comes into one's own.

Electric wire deicing method of the prior art, or dependence is manually beaten mode deicing or is utilized resistance wire coil heating deicing.

Artificial deicing method, remains one of main de-icing method of China at present, because of without configuration relevant device, also just there is no cost of investment.But this method efficiency is low, and environment is very big to performance constraint, operator's life security is also difficult to guarantee.

Heating ice-melting method, to make wire self produce abundant heat by the electric current in increase transmission line to come off to avoid covering of ice and snow to amass or existing icing is melted, as excess current de-icing, short circuit current ice-melt, DC ice melting etc., but all there is larger problem in these methods.Excess current de-icing system loading is large, and interruption duration is long, and operation easier is large.The voltage drop that when short circuit current ice-melt, short circuit causes is very large on transmission system impact, and especially the short circuit of 220KV and above high-tension line has a strong impact on the normal power supply of transmission system; On the other hand, short circuit ice-melt power consumption is large, also needs to revise protection definite value, but also must under short-circuit conditions, guarantee the power supply of system safety and responsible consumer, and operating process complexity, loaded down with trivial details, requires high to dispatcher.

Summary of the invention

For the deficiencies in the prior art part, the utility model aims to provide a kind of voltage wire ice removing device, guarantees to improve deicing efficiency, and easy to operate.

For solving the problems of the technologies described above, the technical solution adopted in the utility model: a kind of voltage wire ice removing device, comprise vehicle frame and bracket, a pair of front wheel and a pair of rear wheel are set in the both sides of vehicle frame, be fixed with connecting rod straight down in the bottom surface of vehicle frame, lower end at connecting rod connects bracket, motor A is installed on bracket, motor A connects output shaft, one end at output shaft is equipped with crank, at the outer end of crank hinge-coupled jump bit, in crank rotation process, jump bit contacts with peripheral high-voltage line respectively, on the rear wheel axle of vehicle frame, be provided with motor B, on bracket, be provided with for the battery to motor A and motor B supply of electrical energy, on the connection circuit of battery, be provided with remote control switch.

Also be equipped with in vehicle frame front end both sides the Ice scraping knife that is sleeve-shaped, described Ice scraping knife is enclosed within on high-voltage line.

Adopt technique scheme, by this device frame on high-voltage line, front wheel and rear wheel are used for being assemblied in high-voltage line, then starter motor A and motor B, crank starts rotation, the jump bit of crank outer end beats on icing high-voltage line, jump bit is made up of elastomeric material, as rubber etc., jump bit can be broken the ice on high-voltage line into pieces, but, can not damage high-voltage line, because the outer end of jump bit and crank is hinge-coupled, like this, after jump bit beats on high-voltage line, can be around hinge through, jump bit can not be stuck on high-voltage line, simultaneously, at the Ice scraping knife of vehicle frame front end both sides in the time travelling forward, like this, the ice cube not departing from completely on high-voltage line is removed by Ice scraping knife.

Said apparatus, by mechanical movement deicing, effectively improves the efficiency of deicing, after this device frame is on high-voltage line, due to by straighforward operation, easy and simple to handle.
