Description

  In the present invention, snow or supercooled rain (hereinafter referred to as snowfall in the present invention) falls on road surfaces, girders, pillars, etc. (hereinafter referred to as road surfaces in the present invention) that are exposed to the outside air in snowy areas. If it adheres to the road surface, freezes, or develops snow, in the case of the road surface, the girder and the pillars and pillars develop into icicles, which impede maintenance and have a great social impact. In order to mitigate these effects, the present invention relates to a combination of devices for preventing adhesion of snowfall and the like by spraying an anti-icing agent on the surface of the road surface or the like during snowfall.

  When snow falls on the road surface in a low temperature area, it develops into ice sheets, snow and icicles due to changes in temperature. The manager of the facility prevents development by snow removal, spraying of anti-icing agent, heating, etc. to prevent icy, ice pillars, and snow accumulation, but it is difficult to respond in a timely manner. It is over.

  When snowfall develops on ice, the road surface becomes slippery, making it difficult for the vehicle to travel safely, drastically lowering the traffic function, greatly affecting the local economy, and increasing vehicle accidents.

  Snowfall develops into icicles, and when the temperature rises, the adhesion of the icicles cannot withstand and falls naturally. Falling icicles are heavy and horny, so they can be injured when hitting a spear and can be dangerous if hitting a vehicle.

  When snowfall develops and snowfall deepens, vehicle traffic becomes difficult, traffic functions decline, and the local economy is affected.

  In order to eliminate the cause of icicles and snowfall, facility managers spend a lot of money to heat girders and pillars and remove snow manually.

  The main body such as a road surface has a large heat capacity, and it is difficult to heat or remove snow with good timing.

  The girders and pillars are structurally high in snowing ice, the scaffolding is unstable, and various protrusions are added, making it more difficult to heat and remove snow manually.

Prior art

  Single equipment used in the present invention (anti-icing agent, storage tank, pressure pump, pressure regulator, expansion tank, solenoid valve, spray nozzle, snowfall sensor, radiation thermometer, anti-icing agent concentration sensor, vehicle sensor, control The device, the anti-icing agent supply pipe, the signal line, etc.) are all general commercial products with versatility.

  An anti-icing agent is a liquid or solid material capable of preventing freezing of water and melting ice. An anti-freezing agent that only prevents freezing cannot melt ice, and it cannot prevent freezing by simply melting ice.

  A storage tank is a general container for storing anti-icing agents. The pressurizing pump is a pump that supplies pressurized anti-icing agent to the spraying device.

  The pressure regulator is a regulator for keeping the pump discharge pressure constant. The expansion tank is a storage tank that stores the anti-icing agent at a constant pressure in order to operate the pump efficiently.

  The solenoid valve is an electric valve that supplies anti-icing agent to the spray nozzle. The spray nozzle is a member that sprays the pressurized anti-icing agent onto the road surface.

  The snowfall sensor is a sensor that detects snowfall and precipitation. A radiation thermometer is a thermometer that measures the surface temperature of road surfaces. The anti-icing agent concentration sensor is a measuring instrument that measures the electrical conductivity of the anti-icing agent adhering to the road surface. The vehicle sensor is a sensor that detects a moving vehicle approaching the spraying device. Both sensors are commonly used sensors.

  The controller is a general sequencer for optimally spraying pressurized anti-icing agent using sensor signals and timer functions.

  The anti-icing agent supply pipe or the like accommodates a supply pipe and an electric wire, and the supply pipe is a general steel pipe or resin pipe that supplies the pressurized anti-icing agent to the anti-icing agent spraying device. The electric wire is a signal line that opens and closes the electromagnetic valve of the anti-icing agent spraying device.

  When there is snow on the road surface at low temperatures, and the temperature is low and the temperature change is small, the snow that adheres to the road surface develops into ice and snow, and in the case of the road surface, it becomes an obstacle to traffic. Fall as a lump. In particular, if there is a change in temperature due to temperature or radiant heat, the ice on the road surface becomes slippery, and the snow accretion on the girders and pillars develops into icicles and falls, which can cause serious damage to human bodies and vehicles.

  In order to avoid damage, facility managers use a large amount of money to heat the road surface, etc., and to remove snow and alert them, but it is very difficult to do them accurately.

  In order to solve the above problems, the pressurized anti-icing agent 5 is sprayed on the road surface 4 by a snow-ice preventing device in which the pressurized anti-icing agent supply device 1 and the anti-icing agent spraying device 2 are connected by a supply pipe 3 or the like. In this way, it is possible to prevent the snow from falling on the road surface 4.

  The first device is an anti-icing agent storage tank 11, an anti-icing agent 111, an anti-icing agent pressurizing pump 12, and a controller 15 that combine the anti-icing agent storage tank 11 and anti-icing agent spray nozzles 22.

Preventing snow accretion in automatic operation by connecting a pressurized anti-icing agent supply device 1 combined with an anti-icing agent concentration sensor 153, an anti-icing agent spraying device 2 incorporating a solenoid valve 21 and a controller 23 with a supply pipe 3 etc. Device.

  The third device is a snow and ice prevention device in which a vehicle sensor 231 of a prior art device is added to the second device in order to reduce the influence on traffic.

  Detecting snowfall, etc., by detecting the snow accretion prevention device connected to the pressurized anti-icing agent supply device 1 and one to several anti-icing agent spraying devices 2 within 0.5 m from the surface of the road surface 4 and the like and connected by the supply pipe 3 etc. At that time, the pressurized anti-icing agent 5 is sprayed from the anti-icing agent spray nozzle 22 onto the road surface 4 or the like manually or automatically. The sprayed anti-icing agent 111 is diffused by about 100 m by a passing vehicle in the case of a road surface, and in the case of a column or a girder, the surface is washed away to prevent snowfall or the like from adhering to the road surface or the like.

  Since the anti-icing agent 111 diffused on the road surface etc. 4 is an electrolytic solution, the ice crystals are broken and melted to form a dilute electrolytic solution, and a thin electrolyte layer is formed on the road surface 4 etc. Does not adhere to. As the anti-icing agent 111, an organic formate is effective from the molecular structure.

  The snow accreting prevention device measures the concentration of the anti-icing agent sprayed on the road surface 4 and the like, and the anti-icing agent 111 is sprayed properly, which is economical.

  Since the snow accreting prevention device is a fixed device, the anti-icing agent 111 can be accurately sprayed without being influenced by traffic congestion on the way unlike the anti-icing agent spraying work vehicle.

  Since the anti-icing agent 111 is sprayed on the snowfall of the girders and pillars, it is safe to flow away like rain in the electrolyte solution without becoming an icicle.
