Description

Snow removing liquid spraying device {SNOW REMOVAL LIQUID SPRAYING DEVICE}

The present invention relates to an apparatus for injecting snow removing liquid for freezing of roads, and more particularly, when snow is accumulated or frozen in roads, tunnel entrances or toll gates by snow falling in winter, automatic snow removal liquids for snow removal and thawing. The present invention relates to a snow removal apparatus for preventing traffic accidents caused by sliding of a vehicle in advance, and preventing the injection module for injecting snow removal solution from being blocked or damaged due to freezing.

In general, if snow falls or freezes on the road during the winter months, snowfall or freezing on vulnerable roads such as toll gates, bridges, curves, slopes, and tunnel entrances on the highways may interfere with vehicle traffic. Or cause a traffic accident.

Therefore, it is absolutely required to remove snow accumulated on the road and forcibly thaw the road.

As such, the most common method of removing or thawing snow on the road is spraying snow on the road, such as calcium chloride and thawing agents, or friction agents such as sand or salt, or using snowplows such as scrapers. How to do this is widely practiced.

However, the conventional method of spraying snow or sea ice as described above requires huge manpower, equipment, and cost because snow is sprayed using a car, or a worker moves directly and sprays snow or snow by hand. At the same time, there was a problem that the efficiency of the work falls.

In addition, by spraying the snow remover by manual work, there is a problem that the snow removing agent is not evenly sprayed on the road is not properly made snow removal.

In other words, the road is composed of several lanes, so the width of the road is wide, so when the snow is sprayed depending on the manual work, the snow should be sprayed repeatedly several times, which takes a lot of time to perform the snow removal work. There was a problem of being exposed to the risk of an accident.

In order to solve such a conventional problem, Patent Document 1 is a piezoelectric element and an electrode active polymer element is installed in the lower portion of the pavement to pressurized by the driving pressure and vibration of the vehicle to generate electricity; A heating wire disposed on the pavement and supplied with electricity to generate heat to heat the pavement; A temperature and humidity sensor installed on the pavement to measure temperature and humidity of the road surface; A microprocessor that allows electricity to be supplied to the heating wire when frost prevention and snow removal operations are required according to the measurement result of the temperature and humidity sensor; The road surface freezing prevention and snow removing apparatus using a self-power generation, characterized in that it comprises a capacitor for storing the electricity generated by the piezoelectric element and the electrode active molecule element and supplying electricity to the hot wire.

However, the patent document 1 has to re-pave the existing road due to the piezoelectric element installed in the lower part of the road pavement, thereby there is a problem that takes a lot of time and cost of installation.

In addition, the hot wire disposed on the pavement to perform the snow removal function by generating heat has a high possibility of breakage due to the cars running on it, there is a problem in that maintenance is difficult.
