The present invention relates to a snow melting device for melting snow on a road surface or a roof. 2. Description of the Related Art Conventionally, there has been proposed an apparatus that pumps underground hot water with a pump, sprays the hot water, and melts snow accumulated on a road or the like. [0003] This device has the advantage that the snow melting effect is high because hot water is sprayed on the snow as it is. In addition, since hot water, which is a natural product, is used, there is an advantage that environmental problems such as air pollution do not occur. [0004] However, in this conventional device, since it is necessary to pump underground hot water with a pump, the pump is easily damaged by the heat and components contained in the hot water, and the device is difficult to use. There is a problem that durability is poor. Although a pump having excellent heat resistance and the like can be used, such a pump is expensive. [0005] In addition, this conventional device has a problem that it induces land subsidence because it is necessary to pump a large amount of underground hot water. The present invention has been made in view of the above problems, and provides a snow melting apparatus which has excellent durability, can melt snow effectively, and does not cause problems such as air pollution and land subsidence. That is the task. A description will be given with reference to FIGS. 1 to 3. The underground heat utilizing snow melting apparatus according to the present invention supplies the primary antifreeze circulating between the heat exchanger 1 and the heat collecting apparatus 1 buried vertically in the ground to collect and collect the underground heat. A device for transferring underground heat to a secondary antifreeze circulating in the heat exchanger 5 between the heat exchanger 5 and the radiating pipe 6 provided in the snow melting place 10 and melting the snow in the snow melting place 10 with the heat. And a circulation for circulating the primary antifreeze in the return path 9 of the forward path 8 and the return path 9 provided between the heat collector 1 and the heat exchanger 5 for circulating the primary antifreeze. Pump 7
Is provided. FIG. 1 shows an embodiment of a snow melting apparatus utilizing geothermal heat according to the present invention. This device comprises a heat collector 1,
The heat radiating tube 6 and the heat exchanger 5 are provided. The heat collecting device 1 includes a concentric inner tube 3 having a gap passage 4 formed between the outer tube 2 and the inner tube 3 by concentrically inserting and assembling the inner tube 3 into an outer tube 2 whose bottom is closed. It is of a heavy pipe type and is vertically buried under the ground at a depth of 50 m to 100 m. The radiator tube 6 is provided at a snow melting place 10 such as a road surface or a roof.
In addition, it is provided in a so-called hairpin curve shape. The heat exchanger 5 is provided between the heat collector 1 and the radiator pipe 6, and the heat collector 1 is connected to the outward path 8 for circulating the primary antifreeze with the heat collector 1. And the return path 9. Further, the heat radiating pipe 6 is communicated with the heat radiating pipe 6 by a feed path 11 and a return path 12 for circulating the secondary antifreeze liquid. The return path 9 is provided with a circulation pump 7 for circulating the primary antifreeze. In the present embodiment, the outward path 8 communicates with the gap path 4, and the return path 9 communicates with the inner cylinder 3. In such a configuration, when the circulating pump 7 is driven, the primary antifreeze descends through the upper end of the inner cylinder 3 and enters the gap passage 4 at the lower end and rises. During this rise, geothermal heat is collected. The raised primary antifreeze
It passes through the outward route 8 and reaches the heat exchanger 5. In the heat exchanger 5, the heat of the primary antifreeze is transferred to the secondary antifreeze circulating between the primary antifreeze and the radiator pipe 6 by heat exchange. The secondary antifreeze heated by this heat exchange is
The heat is released by the radiator tube 6 to melt the snow accumulated in the snow melting place 10 or prevent the snow from accumulating. The primary antifreeze deprived of heat in the heat exchanger 5 is:
Via the circulation pump 7, it is supplied to the heat collector 1 again to collect the underground heat. By repeating such a circulation, the snow in the snow melting place 10 is continuously melted. In this snow melting apparatus, the underground heat is collected with a primary antifreeze, and the heat is used to melt the snow. Antifreeze. This primary antifreeze has a significantly lower temperature compared to hot water in the prior art. Further, since the circulation pump 7 is provided in the return path 9 through which the primary antifreeze liquid after the heat exchange passes, the primary antifreeze liquid has a lower temperature than that of the forward path 8. Therefore, the circulation pump 7
Does not break down due to the influence of heat or components contained in hot water, and as a result, the durability of the device is greatly improved. At the same time, a conventional pump can be used, so that the device can be inexpensive. Since the heat exchanger 5 is provided to transfer the heat of the primary antifreeze to the secondary antifreeze, the temperature of the primary antifreeze is rapidly reduced by the heat radiating pipe 6 unlike the case where the primary antifreeze is directly supplied to the heat radiating pipe 6. No, it can always be kept above a certain level.
Therefore, the temperature of the secondary antifreeze that absorbs the heat is always
It can be maintained at a certain temperature or higher required for snow melting. Therefore, effective snow melting can be continuously performed for a long time. When performing snow melting, although it depends on the location, it is often more effective to continuously apply a constant low temperature for a long time than to apply a high temperature in a short time. Based on such recognition, the apparatus according to the present invention provides the heat exchanger 5 between the heat collector 1 and the heat radiating pipe 6 to continuously maintain a temperature not lower than a certain temperature required for snow melting for a long time. To be able to give to. If it is desired to obtain a high temperature for a long time, a heat pump may be provided instead of or together with the heat exchanger 5. Further, since the underground heat utilization apparatus utilizes underground heat, there is a great advantage that problems such as land subsidence and air pollution do not occur. The snow melting device according to the present invention can be used as a heating device such as floor heating in addition to snow melting on a road surface or a roof. FIG. 2 shows another embodiment of the underground heat utilizing snow melting apparatus according to the present invention. The feature of this device is that, contrary to the embodiment shown in FIG.
Is to pass through. This device is also excellent in durability and can effectively melt snow without causing a problem such as air pollution, similarly to the above-described device. Note that the heat collector 1 is not limited to the concentric double tube type shown in the present embodiment, but is a so-called U-shaped as shown in FIG.
It may be a character type. In the U-shape, a partition wall 14 is provided at the center of a tube main body 13, and two passages 15 are formed in parallel. The heat exchanger 5 and the circulation pump 7 can be operated by a solar thermal power generator or an internal combustion engine power generator in addition to a commercial power supply. As shown in FIG. 4, the solar power generation device absorbs sunlight with a solar panel 16, stores electricity in a storage battery 19 in a storage battery box 17 via a control board 18 that operates when charging is necessary, and requires a controller 20. An amount of electric power is supplied to the heat exchanger 5 and the circulation pump 7. According to the present invention, a geothermal heat utilizing snow melting apparatus is provided.
The low-temperature primary antifreeze is passed through the circulation pump 7, and since the circulation pump 7 is provided in the return path 9, the primary antifreeze is still lower in temperature after heat exchange. Does not break down due to heat or the like.
Therefore, the durability of the device is greatly improved. Further, since the heat exchanger 5 is provided between the heat collector 1 and the heat radiating pipe 6 to transfer the heat of the primary antifreeze to the secondary antifreeze, the temperature of the secondary antifreeze is always kept above a certain level necessary for melting the snow. Can be kept. Therefore, effective snow melting can be continuously performed for a long time. Further, since the underground heat utilizing snow melting apparatus utilizes underground heat, it does not cause problems such as land subsidence or air pollution.
