Leading, construction cost is low, executive capability is strong, short construction period, has been the mark post enterprise of Chinese going global.By 2015
End, Chinese Railway operation total kilometrage and high-speed railway operation mileage respectively reach 12.1 ten thousand kilometers and 1.9 ten thousand kilometers, it is contemplated that 2030
Railway operating kilometrage target is 200,000 kilometers after year.The traction locomotive of high ferro is by the pantograph on locomotive or motor-car roof
Slide block contact the electric energy transfer of electric substation to traction locomotive with the sliding friction of contact line.Cold district is due to long-time
Sleety weather, make contact line be frozen parcel, gradually form icing and even drip and slip, the icing in contact line is for locomotive
Harm is huge, not only affects the railway system normally to run, and can also cause contact line because of extra the increased weight of frost, is made
Into the failure of caving in of tower pole support.There are at least 7 trains in the Beijing-Shanghai express railway of July 13 in 2011, because icing causes contact line
Failure stop off, is particularly acute in the northern area of China.
High ferro locomotive speed is fast, and operation train number frequency is high, contact line is liftoff height, is again that high voltage supply (pacify by 25KV noncontacts
Full distance is 20CM), contact line icing is removed, sleet, haze have a difficulty, and icing is not removed and just can not meet electric power machine overall height
The stream that takes of speed operation is required.Although existing de-icing method can remove icing, deicing effect is undesirable.Particularly coldly
The sleet in area, ice and snow weather, often front just handle well, back freezes again, and the icing of contact line has had a strong impact on electric locomotive
Operation take stream.
Chinese patent literature (the day for announcing：On September 1st, 2010, notification number：CN201566513U a kind of electrification) is disclosed

Disconnecting switch, uplink and downlink contact net by supply arm end partition bipolar load-break switch be connected into ice-melt loop.
Above-mentioned technical proposal solves the problems, such as to be attached to the icing on contact line surface by Joule heat thawing.But this skill
Art scheme needs power failure segment processing, and time-consuming, and energy consumption is more.
Chinese patent literature (the day for announcing：2-015 April 29, notification number：CN204296473U) disclose a kind of by electricity
Bend slide plate, including upper surface is provided with the conductive bracket of locating slot, is provided with what is electrically connected with conductive bracket in the locating slot
Conductive slide plate, the front end of the conductive slide plate is provided with the ice scraper part for striking off frost on contact net, the ice scraper part
Sustained height plane is near the surface of contact net near the surface of contact net with the conductive slide plate so that ice scraper part can
To contact with the frost on contact net well, while will not also hinder conductive slide plate to carry out power taking so that scrape ice function and take
Electricity Functional becomes one, and train does not affect power taking when ice is scraped；Meanwhile, scrape deicing using the mechanical property of ice scraper part
Frost.
Above-mentioned technical proposal solves the problems, such as power train, and in cold weather power taking is difficult, but this technical scheme is sharp
Defrosting effect is scraped with the mechanical property of ice scraper part poor, removed not thoroughly, be easily damaged contact line.
The content of the invention

Electric current, locomotive moves ahead.
When having icing in sleet, haze, contact line, the driver in locomotive 1 first opens the illumination in joystick control 26
Lamp 22 and photographic head 25, convenient observation ice coating state.Open the first valve 7, the second valve 21 again to provide to flame device 9 side by side
Mixed gas, then open ignition switch 27 and light bocca 24, and by the burning of bocca 24, simultaneously flame, to contact line, makes contact
Icing on line is heated and melts rapidly, then by adjusting the gas output of the first valve 7, the second valve 21 controlling bocca
The size and temperature of 24 jet flames.Icing in contact line is subject to outside the flame of the injection of bocca 24, also by from flame
The impact of gas injection in mouth 24, makes the icing also not melted completely prematurely pop out contact line 5 and is shed to deicing device 3
The bottom of U-shaped groove.These prematurely pop out the icing block of contact line, and cold snap and locomotive are easily made during running at high speed
Into secondary icing, to prevent secondary icing to be provided with heater 16 in the cavity body of deicing device 3.Added by heater 16
After icing after heat melts completely, the overfall 17 along the U-shaped groove rear end of deicing device 3 flows out.
Typically deicing device 3 is arranged on locomotive head, pantograph 4 is arranged on the tailstock, it is therefore an objective to flame device 9
After the heating of contact line flame, icing has the process fully melted and come off, and headstock and tailstock spacing are bigger, and the time difference is longer, covers
Ice-out is more abundant, and the stream that takes that can more meet electric locomotive high-speed cruising is required.Melt the icing and flame temperature in contact line
Height, the length of heat time heating time and motor-car the speed of service it is relevant.
The deicing device speed is fast, and efficiency high can quickly remove the icing in contact line, reach the mesh of rapid rush-repair
, the normal power taking of pantograph pan 15 is enable, EMUs is normally run.
A kind of high ferro electrical contact line deicing device, solves motor-car contact line in the state of not having a power failure, driver's cabin
Interior i.e. achievable maintenance de-icing work is time saving and energy saving.Such as the flame device repacking of deicing device is arranged on locomotive is used for
Road snow removing, except good effect is obtained on ice.
Those skilled in the art are inspired by the device, and the structural change for carrying out on this basis is in this patent
Protection domain within.
