Description

Anti-icing Spray Apparatus for High-speed Train}

The present invention relates to an anti-icing liquid spraying device for high-speed trains, and more particularly, by spraying high-viscosity anti-icing liquid to high-speed trains to promote continuous adhesion efficiency of the anti-icing liquid and at the same time to efficiently prevent freezing generated in high-speed trains. It relates to an anti-icing liquid injection device for possible high-speed trains.

In general, railroad vehicles such as trains and subways run along structural rails, and securing the safety of trains and passengers is very important as a means of transportation for transporting many people or goods. Furthermore, since the safety of railroad vehicles is becoming more important due to the recent opening of high-speed trains and the high-speed and high-density of existing lines, technical research on safety inspection, maintenance, and management of railroad vehicles is being actively conducted.

Here, a railway vehicle is composed of a wheel part, a chassis part, a body part, and an accessory device. Among them, the wheel part is fixed to one axle. The part supported and connected to the wheel view must have bearing capacity to withstand high-speed operation and load, and is the basic skeleton of a vehicle to which safety devices such as connectors and brakes are attached. is composed of a coupler capable of connecting vehicles to each other and a brake device capable of controlling speed.

Furthermore, the bogie is a driving device of a railway vehicle, and is a key device of a vehicle that supports the body and transmits the pulling force and braking force to the front and rear vehicles. It is a very important part directly related to driving stability and riding comfort.

However, when it snows in winter, snow sticks to the bogies, causing accidents and breakdowns of railroad vehicles, and it is difficult to inspect vehicles.

As a prior art that has been disclosed to solve the above problems, Korean Registered Patent Publication No. 1407940 (2014.06.10.) discloses an anti-icing device for a railroad vehicle that sprays an anti-icing liquid to prevent freezing of the railroad vehicle. An anti-icing liquid supply unit for receiving and supplying the anti-icing liquid, a spray unit installed around the rail through which the railway vehicle passes and spraying the anti-icing liquid supplied from the anti-icing liquid supply unit to the railway vehicle, and installed outside the spray unit and an anti-icing bulkhead preventing the anti-icing liquid sprayed from the spraying unit from scattering around the rail, and the anti-icing liquid supply unit includes a tank for storing the anti-icing liquid, and connecting the tank and the spraying unit to the tank. A supply pipe for supplying the anti-icing liquid stored in the injection unit to the spray unit, and a spray pump provided in the supply pipe to suction the anti-icing liquid stored in the tank and discharge it to the spray unit, thereby forming an anti-icing liquid film on the surface of the railway vehicle. An anti-icing device for a railway vehicle is known which can easily perform a vehicle inspection while preventing accidents and breakdowns of a railway vehicle by preventing icing.

However, in the case of the prior art described above, it is only possible to maintain the attachment state for one week in a train running at a typical speed of around 100 km/hr, and a high speed running on a rail at a high speed of 200 km/hr to 400 km/hr or more. Since all the anti-icing liquid is removed during train travel, it is difficult to continuously exert an anti-icing effect, and even when a high-viscosity anti-icing liquid is simply developed and applied, it is difficult to spray smoothly.

In addition, conventionally, there is a problem in that it is difficult to recover the anti-icing liquid and the maintenance cost increases because it is operated only with a structure that can be simply sprayed because it is operated with only one tank for storing the anti-icing liquid.
