Title:
LIQUID ANTI-ICING AGENT SUPPLY DEVICE AND LIQUID ANTI-ICING AGENT SUPPLY METHOD
Document Type and Number:
WIPO Patent Application WO/2013/121591
Kind Code:
A1
Abstract:
The invention addresses the problem of providing a liquid anti-icing agent supply device for which burying in the road surface is unnecessary and setting on long sections of road surface is possible and which can control multiple spraying means with a single device. A liquid anti-icing agent supply device provided with: a sensor unit for detecting various external conditions; a storage tank for storing the liquid anti-icing agent; road surface supply units for supplying the liquid anti-icing agent to the road surface via spray nozzles; and a liquid supply control unit that, according to the detection results of the sensor unit, controls the pressure of the liquid anti-icing agent supplied from the circulation tank to the road surface supply units as well as the open period and opening intervals for the electric spray valves of the road surface supply units. The road surface supply units are provided with accumulator-type storage tanks with filler gas, spray pressure adjustors and electric spray valves. Since liquid anti-icing agent stored in a pressurized state in the accumulator-type storage tanks is supplied to the road surface by spraying via the electric spray vales and spray nozzles, setting on long sections of road surface is possible and multiple spraying means can be controlled with a single device.
