産業上の利用分野
この発明は極めて省エネルギー性の高い融雪装置に関す
る。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a snow melting device that is extremely energy efficient.
従来の技術
従来降り積った雪を融かそうとすれば、地下水を汲み上
げて散水したり、更にその水を加熱して散水することも
あり、多大の外部エネルギや燃料を必要としていた。Conventional Technology In the past, in order to melt fallen snow, groundwater had to be pumped up and sprinkled, and the water had to be heated and sprinkled, which required a large amount of external energy and fuel.
問題点を解決するための手段
この発明はヒートパイプを応用し、その一端を地表面に
近く地中にたて方向に設置し、ヒートパイプの内部には
蒸気の流れを制御するダンパが取り付けられている。そ

検知し、降雪がなく、かつ地中の温度が地表面温度より
高い場合のみ、ダンパを閉じるようにしたものである。Means for Solving the Problems This invention applies a heat pipe, one end of which is installed vertically underground near the ground surface, and a damper is installed inside the heat pipe to control the flow of steam. ing. Sensors detect snowfall, ground surface temperature, and underground temperature, and close the damper only when there is no snowfall and the underground temperature is higher than the ground surface temperature.
実施例

図とも２４は地表端、２５は反対側の地中端とする。In the heat pipe, there is a wick 22 and a steam passage 23 in the container.
, and a damper 21 for blocking the airflow. 3 is a sensor for the ground surface temperature T+, 4 is a sensor for the underground temperature T2, 5 is a snowfall sensor using, for example, a phototube, 10 is a damper adjustment device, 6 is a signal line to the damper, 7, 8.9 is a signal line with each sensor. Moreover, FIG. 2 is an enlarged explanatory diagram of the heat pipe 2, and FIG.
In both figures, 24 is the surface end, and 25 is the underground end on the opposite side.
夏期の地表面温度Ｔ＋が高く、地中温度Ｔ２が低いとき

の熱を地下に貯える作用をする。When the ground surface temperature T+ is high in summer and the underground temperature T2 is low, the damper 21 opens and the medium is heated at the ground surface end 24 and becomes steam.1. The medium passes through the passage 23 as indicated by the envelope arrow 26' and emits heat to the surroundings at the underground end 25, condenses and becomes a liquid, which then flows through the wick 22 as indicated by the dotted arrow 27 due to capillary action.
', and reaches the underground end 24, thus acting to store the heat from the earth's surface underground.
次に降雪時には地表面温度Ｔ、の方が地中温度Ｔ２より
低いので、今度は地中端２５で吸熱して媒体は蒸気とな

雪を融かす。熱はヒートパイプ自体の作用で夏期に地中

めて省エネルギ型の融雪装置である。Next, during snowfall, since the ground surface temperature T is lower than the underground temperature T2, heat is absorbed at the underground end 25 and the medium becomes steam, which rises up the passage 23 as indicated by the dotted arrow 26 and rises to the surface end 25.
As it radiates heat and melts, the medium condenses and becomes a liquid, which descends in the wick 22 as shown by the solid arrow 27 and returns to the underground end 25, thus carrying the heat from the earth to the earth's surface.
melt the snow Heat is generated by the heat pipe itself, which pumps out the heat stored underground in the summer and uses it to melt snow in the winter, making it an extremely energy-saving snow melting device.

’ｌ’２の場合のみである。Next, snowfall sensor 5 does not detect snow, and temperature sensor 3.
According to 4, when the underground temperature T2 is higher than the ground surface temperature T1 (which is often the case in winter), there is no point in transporting underground heat to the ground surface even though there is no snow; Only when does not detect snow and 'r+ <'l'2,
The damper regulator is closed and heat transfer is stopped. Even if snow is not detected (even if T, >T), it would be meaningful to transport and store heat from the earth's surface underground, which is almost impossible. At that time, it is the same as in summer, the damper is open and the heat pipe works regardless of whether there is snow or not.The damper is closed and the heat pipe stops working regardless of whether there is snow or not. <
Only in the case of 'l'2.

運び上げることができる。Fig. 3 shows another embodiment in which a plurality of heat pipes 2, 2', 2", etc. (three in the figure) are installed vertically under the ground 1. of heat can be stored deep underground, and when it snows, a large amount of heat can be carried up from deeper to the ground surface.

地表面に運ぶことはない。Effects The snow melting device of the present invention has such a structure, and by the action of the heat pipe, heat from the ground surface is stored underground in the summer, and when snow falls in the winter, the heat from the ground is used to melt the snow on the ground surface. It is an extremely energy-saving type, and the damper inside the heat pipe cuts off the flow of heat when there is no snow and the ground surface temperature is low, so the underground heat is wasted away at the ground surface. Never carry it.
