Description

AUTOMATICALLY UPON SNOWS OR ICE ROAD SPRAY TO SPRAY MY SPRAY SYSTEM UNATTENDED}

The present invention relates to a spraying system for spraying a snow removing agent, a thawing agent, or a spreading material such as sand, grains, particles, chips, etc. More specifically, it detects a climate factor using a temperature sensor, a humidity sensor, an ultrasonic sensor, and the like. The present invention relates to an unmanned spreading system that automatically spreads the spreading material for snow removal and thawing when snow falls or the road freezes.

In general, when snow falls or freezes during the winter months, snow accumulation or freezing on roads such as bridges, curves, uphill roads, tunnel entrances, etc. can lead to tremendous obstacles in the traffic and not only safety accidents. As the risk is increased, rapid snow removal and thawing should be performed.

Conventional methods for removing snow from roads or thawing roads include spraying snowplows such as calcium chloride or a friction agent such as sea ice or sand on a road, or performing snow removal using a snowplow such as a scraper.

However, such a conventional method requires the use of a vehicle and the like, and requires a great amount of manpower and equipment, as well as the workability is poor because it needs to spray snow removal agent or thawing agent by hand.

In addition, if the heavy snow falls snow on the road sharply accumulates, if the rapid snow removal is not performed, the traffic of the vehicle is paralyzed and the risk of traffic accidents increase, but according to the conventional method described above, the snow removal operation is considerably delayed. Likewise, it cannot cope with a situation that requires rapid snow removal.

In addition, in the relatively wide section of the road it is difficult to perform the snow removal evenly in each lane by the conventional method described above, when performing the snow removal must control or restrict the traffic of the vehicle for the safety of the workforce. In particular, when the snow removal is carried out at a time such as midnight or dawn, it is a great burden on the worker, there is a fear that a variety of work safety accidents that occur.

So far, various methods have been researched and developed.

Examples include the 'snow plow spraying device' of Korean Patent No. 10-225035, the 'road marker bottle with spray function' of Korean Patent No. 10-750937, and the 'snow plow spraying' of Korean Patent No. 10-684621 System, 'remote control method of snow removal system using smartphone' of Korean Patent No. 10-1066210, 'remote control anti-icing system and operation method thereof' of Korean Patent No. 10-839024.

The above-mentioned prior arts are proposed to replace the dust spreading or spraying with the mechanical spraying or spraying or to remotely control the spreading spraying at a remote location as a technique proposed for the preliminary recovery and prompt action of the road surface necessary for snow removal or ice making.

First, Korean Patent No. 10-225035 'Road Snow Plowing Apparatus' is composed of a plurality of injection holes connected to the installation chamber, the snow removal storage tank, the compression pump, the compression pump, the center line and the central separator of the road, or Spraying snow remover to the road surface by installing a nozzle to have a certain height from the edge road surface.

However, the prior art as described above is difficult to unify management because the spraying means and the spraying means are separated. It is also low in utilization as a road facility for simply spreading the necessary spraying material on the road surface. And since it is operated by direct operation, it is difficult to respond early, it is restricted in the installation position selection, and mobile installation is impossible.

In addition, Korean Patent No. 10-750937 'Snow Snow Plow Sprayer' is a main body with a reflecting plate, a support that is integrally installed in the lower part of the main body to support the main body and the fastening bolts to be fastened to the support It is a road marker composed. In the inner space of the main body, there is a built-in spray nozzle connected to a liquid supply source and a connector to eject the liquid. The main body is buried in the ground through the bracket and is not separated, but sprays the contents of the liquid source from the outside into the spray nozzle through the pump.

However, the prior art as described above is floating in the central separator portion and is likely to be clogged or damaged. In addition, remote control of the timing of injection is impossible, making early response difficult. In addition, since the liquid supply and the injection means are separated, unified management is difficult and there are many restrictions in the installation location selection.

In addition, the 'snowplow spraying system' of Korean Patent No. 10-684621 is a rail constructed on the shoulder of the road, a truck spraying snowplow, a chloride tank supplying chloride water, a drive control unit for remote control of the truck, chloride It consists of opening and closing control unit for opening and closing the water tank. It is sprayed on the road by receiving the chloride water from the chloride tank while the bogie is remotely driven and moved along the rails.

However, the prior art as described above can spray the chloride water by remote control, it is difficult to spray the chloride water in the right place because it can not accurately determine whether the snow falls or the road surface is frozen in the place where the truck is installed in the remote place. To do this, CCTV must be installed at each location where the truck is installed, and the manager must continuously monitor the CCTV.

And the 'remote control method of the snow removal system using a smartphone' of Korean Patent No. 10-1066210 as a component of a remote terminal device for operating a smartphone, a mobile communication network, a nozzle. It transmits SMS (Short Message Service) data through a smartphone to operate the nozzle of the remote terminal device to drive or monitor the snow removal control system.

However, the prior art as described above can remotely control or monitor the snow removal control system, but it is difficult to check whether the snow falls on the place where the snow removal control system is located or whether the road surface is frozen.
