Description

{A Automatic spraying system of liquid freezing inhibitor of road-diffusion calcium acetate to prevent black ice and prevent slip in winter}

The present invention removes snow accumulated on bridges or ramp sections of roads in winter and sprays an eco-friendly anti-freeze agent to prevent condensation and slipping in order to prevent the road surface from freezing due to moisture. It relates to an automatic spraying system of a liquid freeze inhibitor for calcium acetate diffusion to prevent road diffusion.

In general, snow and ice melting devices to remove snow or ice from roads in winter are mainly installed in ramp sections or entrances and exits, and spray calcium chloride solution (salt water) to remove snow or ice from roads to prevent road safety. have.

Such a salt water spraying device is not eco-friendly due to salt water, so it does not overcome the disadvantages of corroding metals such as vehicle age or roadside steel structures, and the more it is used due to side effects after use, it accelerates environmental pollution such as water pollution. There is a problem.

In addition, black ice, which refers to the phenomenon of road freezing, in which the snow melted on the road freezes back into thin ice when the temperature suddenly drops recently, has emerged as a big problem in winter.

In addition to snow or rain on the road, the black ice looks like asphalt to the naked eye even on a clear day, but due to black ice, which is thin ice, there is a continuous sliding accident on the road recently, and it is 14 times more slippery than normal roads and 6 times more slippery than snowy roads. When driving at 50 km, the braking distance is more than four times longer than that of a dry road, so you can face the risk of unexpected accidents on the road.

9 is a registered patent No. 10-1528129 automatic salt water spray system, as shown, the automatic salt water spray system is a main server 10 installed in the snow removal situation room, the main server 10 and the network sharer (11) The mobile 20 that can be linked and controlled through the main server 10 and the network router 31 are wirelessly connected to the CCTV 30 to monitor the snow removal site situation, and the main server 10 and The Ethernet module 40 connected between the network sharer 31 and the local server 50 for communication with the local server 50, the local server 50 installed in the field control room S, and the local server Through the input module 51 to 50, the traffic measurement sensor 60 (60a) that transmits the traffic volume data that measured the real-time traffic volume of the snow removal site, and the main through the output module 52 of the local server 50. It consists of a plurality of I-type spray nozzles 90 and Y-type spray nozzles 100 for automatically spraying salt water by driving the actuator 80 according to the command of the server 10.

However, the conventional automatic salt water spray system is a system that detects vehicle traffic while checking the snow removal site and sprays salt water. Since salt water has to be sprayed in, it is not possible to spray salt water in advance, so the snow removal cannot be effectively processed because salt water is sprayed in the state of snow, and it is a structure that cannot remove black ice at all. The death caused many problems in the surrounding environment.

In addition, the prior art has a problem in that maintenance time and cost are significantly increased because it is difficult to perform long-term storage or normal functioning and maintenance of the injection system due to deterioration due to rust, etc., so that repair and parts must be replaced every year.

In addition, the liquid freeze inhibitor (KMG) is spread to the road surface by the wheels of the moving vehicle, so that the maximum effect can be exerted with a minimum consumption amount, and the antifreeze agent sprayed on the road surface is used as an additive for a considerable amount of time (3 days~ 7th) It does not evaporate and remains on the road surface to prevent freezing as well as to prevent slipping. The purpose of this is to minimize equipment and installation costs due to compact equipment.
