Description

Runway snow removal system using laser {SHOW REMOVAL DEVICE USING LASER}

The present invention relates to a runway snow removal system using a laser, and in particular, using laser irradiators fixed on both left and right sides of a runway to efficiently remove snow accumulated on a large area on a road, such as a runway, as well as a laser When irradiating, it is irradiated by expanding the radiation range of the laser through the lens and tilting in the up and down directions to improve the snow removal efficiency according to the laser irradiation, or tilting the lens in the up and down directions on the snow removal vehicle. It relates to a runway snow removal system using a laser whose structure is improved so as to efficiently perform snow removal on a road having a large area such as a runway by disposing a laser irradiator that is irradiated by expanding the radiation range of the laser.

In general, calcium chloride is used for snow removal. The calcium chloride is used as the most representative snow removal agent because it has excellent performance, low price, and convenient supply because it can be mass-produced in a factory as a snow removal agent.

However, calcium chloride not only interferes with plant growth and corrodes vehicles, but also corrodes roads and creates holes called 'potholes' in various places, increasing the risk of traffic accidents. In addition, it flows into rivers near roads, impeding the growth of crops in the area and causing water pollution in drinking water sources. Therefore, due to the problem of calcium chloride, various eco-friendly snow removal methods have been proposed to replace it.

A typical example is an eco-friendly snow remover made from recycled food waste. It has an eco-friendly advantage of extracting alternative substances from food waste and concentrating organic acids using a microfiltration membrane to melt snow well.

However, the biggest problem with this eco-friendly snow remover is that it is more expensive than general calcium chloride.

Recently, it has decided to purchase and supply only eco-friendly snow removal agents that have been certified according to environmental regulations, making it inevitable that the cost of snow removal agents will increase.

Eco-Traction, an eco-friendly snow remover made of natural Canadian oxalate without harmful ingredients, is five times more expensive than calcium chloride.

In addition, eco-friendly snow removal agents are said to be effective only one hour after they are sprayed, so there is a point that there is a problem in using them in areas where damage is expected due to heavy snowfall.

On the other hand, a snow removal method using a snow removal agent and a snow removal vehicle equipped with a snow removal device are used in parallel or either one is used.

The snow removal device is mounted on a vehicle and used for snow removal. Looking at the snow removal operation process, first, a bucket that is in close contact with the road surface pushes a large amount of snow to the left or right side of the road. carrying out snow removal work.

Therefore, the bucket moving in close contact with the road surface sequentially pushes a large amount of snow to the left or right side of the road so that the snow is loaded on the edge of the road, and the snow loaded on the edge of the road is transported using a separate transportation means. Since it has to be transported to another place, there is a problem in that it takes a lot of manpower and cost to process the snow loaded on the edge of the road after the snow removal operation is completed.

In addition, looking at the method of snow removal using waste heat of a vehicle, the snow removal device using the exhaust gas of a vehicle of the Republic of Korea Utility Model Publication No. 1986-1961 (19860818 announcement) is located at the tip of a flexible tube that is inserted into the exhaust pipe of the vehicle. A ring is formed at the tip of the pipe-joined injection pipe, and one end of the line is tied to each other. Hang the line on the rollers formed on the left and right sides of the bracket. It is made by connecting it so that it can be wound.

In addition to the snow removal method using the waste heat of the existing vehicle, the snow removal method using a laser is being developed. As disclosed in "Apparatus" (registration date: 2016.06.28), an extrusion means configured on one side of the exhaust line to extrude the exhaust gas exhausted through the exhaust line to the front of the wheel according to the control signal of the selection switch comprising; The extruding means includes: a first branching part configured on one side of the exhaust line to change the exhaust direction of the exhaust gas; a second branch for branching the exhaust gas exhausted through the first branch to be discharged to the wheel or to the outside; and a nozzle located in front of the wheel, so that the snow accumulated in front of the wheel is dispersed by pressure and melted in heat as the exhaust gas induced through the second branch is ejected by pressure. .

As another prior art related to the existing laser snow removal, as disclosed in Korean Patent Publication No. 10-2011-0128702 "Car with snow removal function" (published date: 2011.11.30), it is possible to secure vehicle driving or braking function. In order to do this, it is located in front or behind the driving wheels of a vehicle and irradiates a laser on the road surface to remove snow or ice from the road surface.

Since the prior art related to the conventional laser snow removal apparatus is a method of irradiating a laser along the traveling direction of the vehicle, it merely uses the thermal energy of the laser, and thus the snow removal efficiency cannot be improved.

In addition, in the case of the existing snow removal device, since it is necessary to perform snow removal while driving on a road where the road surface is icy while moving places such as a runway, there is a risk of accidents due to vehicle slippage, and the working time required for snow removal operation This takes a long time, and there is a disadvantage that the snow removal operation range is not widely applied.

Korean Utility Model Publication No. 20-0480756 "Eco-friendly vehicle snow removal device using vehicle exhaust heat and optical laser" (Registration date: 2016.06.28) Korean Patent Application Laid-Open No. 10-2011-0128702 "Automobile with Snow Removal Function" (published on: 2011.11.30)
