Snow melting device using geothermal energy

Abstract

Provided is a snow-melting device melting snow without generating a problem such as a ground subsidence settlement, the scattering of water, the freezing of a road surface or the like by effectively utilizing clean inexpensive energy. A heat exchange 10 in which an internal cylinder 12 is installed concentrically in an external cylinder 11 and buried vertically in a ground and a first liquid medium is circulated in the internal cylinder and terrestrial heat is collected, a radiating pipe 20, which is buried in a hairpin curve shape just under a road surface 1 and in which a second liquid medium is circulated in the pipe 20 and snow on the road surface 1 is melted by the heat, a heat pump 30, by which the temperature of the heat of the first liquid medium is increased and the heat is transferred to the second liquid medium, and a heat storage tank 40 in which heat is stored are secured. The heat exchanger 10 is connected to the heat pump 30 to communicate therewith by a first circuit 31 while the heat pump 30 and the radiating pipe 20 are connected by a second circuit 32 to communicate with each other. The first circuit 31 and the heat storage tank 40 are connected by a first communication path 41 to communicate with each other while the second circuit 32 and the heat storage tank 40 are connected by a second communication path 42.

Description

technical field [0001] The invention relates to a snow melting device which utilizes collected geothermal heat to melt snow on roads, tracks of lines and the like. Background technique [0002] In the past, in order to melt snow on roads and railway tracks, the method of pumping groundwater from wells and spraying it on the road surface was adopted. Such a method has the advantages of not polluting the atmosphere and low operating costs because it utilizes the groundwater drawn up as an energy source that does not cause pollution. Contents of the invention [0003] However, using the original technology, because a large amount of groundwater must be drawn, it is easy to cause major problems such as foundation subsidence. Moreover, the water sprinkled on the road surface will splash on passing vehicles and pedestrians, and if the outside temperature is low, it will also cause the road surface to freeze, becoming a hidden danger of inducing traffic accidents.
