Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a bridge freeze prevention device and a bridge freeze prevention device,

The present invention relates to a bridge freeze prevention device and a method of controlling a freeze prevention device. In order to prevent the freezing phenomenon occurring in the winter on a bridge road passing through the sea or a river, an anti- The present invention relates to a bridge freezing prevention device and a method of controlling a freezing prevention device for preventing and removing freezing of a road surface by spraying a calcium chloride solution mixed with calcium chloride into a river when the bridge is a steel bridge.

Generally, there is freezing phenomenon by snow or rain in the winter on the bridge or overpass road.

Among the reasons for freezing in bridges and overpasses, it is necessary to drain water on both sides of the road during winter rainfall or snowfall, but when the drainage channel is frozen or foreign matter is generated, water generated by rainfall or snowfall is not drained There is a problem that freezing occurs on the road surface due to the frost being frozen immediately.

In recent years, in order to prevent freezing of the road surface, freezing of roads is removed by making a calcium chloride solution sprayable to both sides of a snowmobile or a bridge and an overpass.

However, it is inconvenient for the administrator in charge of the bridges provided for spraying the calcium chloride solution to directly move and replenish the calcium chloride solution depending on the usage amount, and it is known whether the calcium chloride solution is exhausted due to frequent injection of the calcium chloride solution due to heavy snowfall There is an inconvenience that an administrator has to check directly.

In addition, there is a problem that the calcium chloride solution must be produced and transported in a certain place.

The production of calcium chloride solution from the bridges installed in the whole country and transporting them, and replenishing them to the respective bridges causes problems such as low production cost and labor cost efficiency.

[

Here, the directions of the nozzle grooves 251, 252, and 253 of the injection nozzle 250 can be manufactured according to the user's discretion.

In addition, the seawater injected through the injection nozzle 250 is injected with a considerable pressure or is sprayed in the form of flowing water. The diameter of the injection nozzle 250 is selected according to the width of the road surface or the road traffic situation .

In addition, the heating coil 260 generates heat only to the extent that it does not freeze by applying a slight heat to the entire nozzle of the injection nozzle 250.

(D) shows an enlarged view of the water collecting tank 130. In the water collecting tank 130, water is sprayed by the spray pump 220 formed on the guard rail 30 on both sides of the road surface, And a heat insulating material 170 is formed on the outer circumferential surface of the transfer pipe 210 to prevent condensation generated inside the transfer pipe 210 by moving the seawater through the transfer pipe 210.
