ヘリポート用融雪装置

Japanese Patent JP7204152

B2

To provide a snow-melting device for a heliport which effectively uses rainwater, is environmentally friendly, and is economical.SOLUTION: A snow-melting device for a heliport has switching valves 29 and 30 for selectively feeding rainwater of a rainwater tank 22 and an aqueous solution of an antifreezing agent aqueous solution tank 24, and pumps 31 and 32. The device has a pipe 34 for supplying the rainwater or the aqueous solution to a takeoff and landing surface 12a of a heliport 12, and collection means 36, 38, 40, 44 and 45 for collecting the rainwater or the aqueous solution sprinkled from a snow-melting pipe 33. A control device 60 for inputting output of an outside air temperature sensor 59 and controlling the switching valves 29 and 30 and the pumps 31 and 32 is also provided. The control device 60 controls the switching valves 29 and 30 and the pumps 31 and 32 from a signal from the outside air temperature sensor 59, and switches a mode in which the rainwater is fed from the rainwater tank 22 and a mode in which the aqueous solution is fed from the antifreezing agent aqueous solution tank 24. The rainwater tank 22 serves as an oil-water separation device, and can sprinkle and circulate the rainwater or the aqueous solution through the pipe.SELECTED DRAWING: Figure 1
