Description

Dispensing system that distributes liquid snow removal agent remotely}

The present invention relates to a spraying system for remotely spraying a liquid snow removing agent, and more particularly, to grasp the temperature and humidity of a place where a spraying system for spraying a liquid snow removing agent is installed remotely and to notify a manager by wireless communication if it is above a reference value. Remote control of the snow remover that prevents clogging due to debris generated after evaporation in the connecting pipe by recovering the remaining solution in the pipe after spraying, as well as allowing remote control of the spray after checking the scene while watching the image. It is related with the spraying system which sprays by air.

In general, when snow accumulates or freezes on vulnerable road surfaces, such as bridges, curved covers, ascents, and entrances to tunnels, including straight roads, it may interfere with vehicle traffic and worsen road usage conditions. The same applies to dust accumulated on the road.

One way to clear and melt snow is to apply snow and snow thawing agents, such as calcium chloride, or friction agents, such as sand and granulated chips. This method is almost impossible to spread the spraying agent on the multi-lane wide road surface, and there are problems with traffic control and obstacles. There is a method of spraying the spraying machine mechanically using the spraying vehicle, but there are problems in traffic control and equipment operation. .

The use of equipment and manpower-dependent snow removal and thawing work requires equipment and personnel input to the site, so rapid snow removal is virtually impossible. For this reason, various methods have been studied.

Representatively, the technology of the 'snow plow spraying device of the road' of the Republic of Korea Patent Registration No. 225035, the 'road marker bottle with the spray function' of the Republic of Korea Patent Registration No. 750937 is known.

The above techniques are proposed to replace the spray spreading machine with mechanical spraying as a technique for preliminary recovery and prompt treatment of roads requiring snow removal.

Patent No. 225035 'Road Snow Plowing Apparatus' is composed of several injection ports connected to an installation room, a snow removing storage tank, a compression pump, and a compression pump, and has a predetermined height from a road centerline, a median separator, or an edge road surface. Install a nozzle so as to spray snowplow on the road surface. This technique is difficult to unify management because the spraying means and the spraying means are separated. It is a road facility for simply spraying the spraying agent needed on the road. It is not useful. It is operated by direct operation. This is impossible to follow and install on the go.

Patent No. 750937 'Road Snow Plowing Apparatus' includes a main body with a reflecting plate attached thereto, a support body which is integrally installed at the lower part of the main body, and a support bolt which passes through the main body and is fastened to the support body. It is a road marker bottle including the main body's internal space is equipped with a spray nozzle connected to a liquid supply source and a connector so that the liquid can be injected. The main body is buried in the ground through a bracket, and the contents of the liquid supply source are not separated. Spray into the spray nozzle through the pump.

This technology is installed in the central separator and is floating, and there is a high possibility of clogging and breakage of the nozzle. Remote control of the timing of spraying is not possible, which makes it difficult to respond early. The liquid supply and the spraying means are separated, so unified management is difficult. There are many limitations in the choice of installation location.

'Liquid spreading device' of the Republic of Korea Patent No. 0985174, it is possible to respond early in snow removal through real-time remote control.

On the other hand, all conventional road liquid spraying apparatus including a remote control function through wired and wireless data communication has a problem in that the spraying agent is sprayed by using the commercial power provided by the main operator as a pump driving power source in common. Therefore, power cable wiring to power the pump system is essential, and there is a possibility of an electric leakage due to leakage of rainwater. Therefore, the electrical stability is low and the operation stops in case of power failure.

In addition, since the facility is left unattended on the road, it cannot cope with expensive electronic parts damage or theft due to carelessness and neglect of monitoring.

In addition, more sophisticated control was required according to the surrounding conditions because it was left on the road and put into operation standby state. For example, managers could provide various information necessary for the operation of the liquid spreading device in real time, such as road condition information and current facility management status. It was necessary to convey. For example, climate and environment information affecting the operation of the liquid spreading device such as temperature and humidity.

In addition, efficient operation can be expected by acquiring and transmitting various information required for remote control operation, but current technology remains in basic power control such as simple power control and pump driving by wired / wireless data communication.

In addition, the conventional remote spraying device is not reinstallable and not free to move, thus making it impossible to adjust or change a simple position. And there is a problem that can not be reused repeatedly.

In addition, since the general power is used as a driving source, the system is impossible to operate in special areas, power failures, and flooded areas where power is not available, and stability is inferior due to the possibility of leakage or electric shock due to water contact while the standby power is flowing. There is this.

In addition, conventionally, in order to install a device for spraying the spraying agent with a pump and spraying on the road, a complicated wiring work and a circuit breaker, etc., in consideration of a short circuit and an electric shock are basically required, so that initial construction and dismantling workability are not good.

As a prior art for solving the above problems, Korean Patent Publication No. 10-1140768 (2012.05.03. Announcement) "remote snow removal system" is a cylindrical body having a storage compartment 101; An outer casing having a pump for pumping the spreading agent and a nozzle for spraying the spreading agent; A remote terminal device having a data communication unit and recognizing and driving data transmitted from an authorized manager terminal for processing the external data received through the data communication unit to control the driving of the pump; A solar cell unit formed by installing a solar panel outside the body and the outer casing to supply power required by power driving components including the pump and the remote terminal device; And a manager terminal for transmitting a control signal to the remote terminal device as data through a wired or wireless communication network and receiving a data signal transmitted from the remote terminal device through a wired or wireless communication network.

However, the above prior art has a problem in that the liquid crystallization agent is coagulated, the concentration is lowered, so that snow removal is not properly performed.

In addition, since the liquid snow removing agent is not completely removed from the connecting pipe supplied to the nozzle after spraying the liquid snow removing agent, there is a problem in that the spraying is not performed properly due to the phenomenon of the liquid snow removing agent remaining in the connecting pipe due to low temperature.

In addition, the prior art is configured to be limited to the liquid snow removal agent stored in the body, so that when the snow falls for a long time it is difficult to spray the liquid snow removal agent, as well as can not fill the liquid snow removal agent can not be properly made There is a problem.
