Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is broadly applicable to roofs, rooftops, roads in snowy areas,
The present invention relates to a snow melting device and a water level double-adjustment tank which utilize exhaust heat of an engine to remove snow from gardens, parking lots, railroad tracks, or obtain water for daily use from snow.

In particular, the third and fourth inventions are such that the main part thereof is movable.

In particular, the fifth invention relates to a water tank capable of double-adjusting the water level of a water tank used for a snow melting device using exhaust heat of an engine. And the sixth invention is
An infrared lamp snow melting means is added to the first invention.

[Prior Art] Conventionally, with respect to snow removal, snow on roofs and roofs in snowy areas has been manually removed using a scoop, and then transported to a river or the like and discarded. In addition, snow on roads was removed by snowplows and groundwater was sprinkled to melt the snow. Furthermore, the snow in the garden and parking lots was thrown away or melted into rivers. And, the snow on the railroad track was removed by Russell cars and rotary cars.

In addition, there was no simple and efficient snow melting device that can move its main part and can be applied to snow melting such as snow removal at many places.

On the other hand, in order to obtain water for daily use by melting snow in cold areas such as high mountains and extreme areas, heating with a heater, which is very inefficient, was used.

Furthermore, there is a water tank that is used for other things such as a snow melting device that uses exhaust heat of an engine, and the water level is adjusted by a float valve, but this was all a tank with only a single adjustment.

And there is no snow melting device that uses an efficient infrared lamp.

[Embodiment] Hereinafter, a snow melting device using an exhaust heat of an engine, a water level double adjustment tank, and a power generation / exhaust heat snow melting device according to the present invention will be described in detail with reference to the accompanying drawings using an embodiment thereof. . FIG. 1 is a side cross-sectional view of one embodiment of the first, fifth and sixth inventions of a snow melting device for utilizing exhaust heat of an engine, a water level double adjustment tank, and a power generation / exhaust heat snow melting device according to the present invention. The figure is shown.

First, there is a water (smelting water) tank 10 as shown in FIG. 1 which is covered with a heat insulating material. Inside the water tank 10 is a radiator 21 of a gasoline engine 20, which cools the engine 20 to an appropriate temperature and at the same time raises the water temperature in the water tank 10. Then, the water 12 in the water tank 10 whose water temperature has risen is guided by the pump 30 driven by the engine 20 to the snowmelt water flow path 41 such as the roof 40 by the water supply pipe 50,
The water discharge part 60 sprinkles water there and melts snow. The water discharger 60 does not necessarily have to be a spring clerk, but may simply be the outlet of the water supply pipe 50. That is, any material that matches the snow melting location may be used.

At this time, it is advisable to adopt a double structure in which the water supply pipe 50 is surrounded by the exhaust pipe 22 as shown in FIG. 1 so that the water supply pipe 50 is warmed by the exhaust heat from the engine 20. Furthermore, it is better to wrap it with a heat insulating material. Exhaust may be directly applied to the water sprinkling outlet of the sprinkler or the like.

Next, the snow melted by this heated and sprinkled water is
It is poured onto the woven and knitted filter 70 that is installed in an inclined shape through the snowmelt water flow path 41. Dust 80 such as gravel and paint fragments is washed away by water on this slope and is naturally slid off and removed. Then, a part of this water falls on the pan 13 of the water tank 10. When the water level in the water tank 10 is below the upper limit line, the upper water quantity adjusting float valve 14 in the water tank 10 opens, and the water from the above-mentioned pan 13 which is the main flow path flows into the water tank 10. This upper water quantity control float valve
When 14 is closed, it will overflow from the filter 70 and out of the water tank 10. This water tank filtered 10
The water 12 that has entered the inside is warmed and is circulated and reused again by the water pump 30 for snow melting.

On the other hand, the engine 20 causes the generator 90 to rotate, and the infrared lamp 91 is turned on by the electricity to melt the snow.

In this way, when the water flowing into the tank 10 is small and the water level in the water tank 10 decreases and reaches the lower limit line,
The lower water amount adjusting float valve 16 of the faucet 15 such as a water supply serving as an auxiliary flow path is opened to supply tap water or the like. Rainwater that has flowed in in excess of the upper limit water level should overflow from the drainage port 17. Of course, if not, it will overflow the portion of filter 70 above. In addition, with the above water amount adjusting float valve 14
The 16 floats may be separated as shown in the figure, but may be shared by both.

Thus, the engine 20 may be insulated by water when installed in the pocket 18 of the water tank 10 as shown by the dotted line in FIG. On the other hand, a water pump 30 may be provided in the snowmelt water flow path 41 to pump up the water 12 and pour it into the water tank 10. The filter 70 is provided with an inclination so that the flow of water from the snowmelt water flow path 41 naturally keeps it in a clean state.

When this snow melting device is not used except in winter, it is advisable to install a drainage cock in the pulp to allow water to drain. It is only necessary that the water for operation snow melting does not freeze at temperatures below 0 ° C, and there is no need for it to be “high-temperature water” at 10 ° C or higher like well water. On the other side of the Sea of Japan side, there are few days when the temperature drops below 0 ° C even during snowfall, and it is only on sunny days during the day that the snow is removed from the roof. And the temperature is 5
It often rises to around 10 ℃. This device is mainly operated when the outside temperature is 0 ° C or higher.

Further, if the water supply pipe 50 is kept warm by using the exhaust gas of the engine 20, there is no fear of ice puncture of the water supply pipe 50. The engine 20 described above does not have to be new and can be used as a second-hand automobile engine and is therefore inexpensive. The water in the water tank 10 should be prepared in case of heavy snow or when it is difficult to melt the snow on a cold day.
A heater 80 may be provided to further heat 12.

Then, as in the side sectional view shown in FIG. 2, the exhaust gas from the engine 20 heats the water 12 in the water tank 10 through the warm exhaust pipe 23 passing through the water tank 10. Will be even more efficient. of course,
Instead of this, a pipe whose both ends are connected to the water tank 10 may be wound around the exhaust pipe 23 of the engine.

On the other hand, if the above structure is divided into two blocks and the main part thereof is made movable, it becomes economical in many cases. That is, it is assumed that the snow melting device is composed of a movable heating unit 1 and a snow melting unit 2 installed in a house, etc., and the movable heating unit 1 is a place where snow melting is required in each house or the like. It is brought in and connected to the snow-melting section 2 installed in, so that it can operate integrally.

The snow melting section 2 is composed of the water supply pipe 50, the water discharge section 60, and the snow melting water flow path 41. And the said heating part 1 consists of the above-mentioned thing other than these.

The radiator 21 does not necessarily have to be a closed type as in the present embodiment, and an open type that is open without the water tank 10 may be used depending on its application. Of course in this case,
If the degree of openness is not reduced in consideration of the degree of exchange of water with the tank 10, the engine 20 will be too cold and it will be difficult to drive it.

Further, the generator may be rotated by the engine 20 and the electric power may generate heat to be used for melting snow on the roof or road.
Further, if the water supply pipe 50 is warmed by the heat, the water passing therethrough is warmed from the beginning of this operation, so that the snow can be efficiently melted. In this case, in the third and fourth aspects of the invention, if the water is heated near the water pump 30, the equipment of the snow melting section can be saved. Of course, it goes without saying that the heat may be used to heat the water in the water tank 10.

For this power generation, it is generally preferable to use a generator attached to the engine itself. At first, the pump is separated from the engine and does not rotate.First, the electricity is used to heat the water in the water pipe 50, etc., and then the water pump is operated to perform the initial operation. Becomes smooth.

Thus, in the embodiment of the present invention, not only the above-described snow removal but also the melted water can be used as domestic water etc. if the snowmelt water flow path and the snow are clean. Hence,
An embodiment in which the power generation engine in a mountain hut or the like and the above engine 20 are shared is also possible. That is, the exhaust heat of an engine used for other purposes such as power generation is not thrown away and used for melting snow.

[Effects of the Invention] Since the snow melting device using the exhaust heat of the engine, the water level double-adjustment tank, and the power generation / exhaust heat snow melting device according to the present invention are configured as described above, they are used for snow removal during snow removal. You no longer have to spend a lot of effort and money. And because the thaw water is used as the hot water for melting snow, groundwater is not necessary and it is a water-saving type. On the other hand, there is a possibility that very economical domestic water may be easily obtained by using the exhaust heat of the engine required for other purposes such as power generation and the amount of power required to rotate the water pump. became. And since the water heating uses the exhaust heat from the engine, it became simple and efficient.

Further, in the third and fourth aspects of the invention, since the heating part which is the main part of the invention is movable, only one heating part can be used for the snow melting part installed in each place. Moreover, since the snow melting portion may be equipment such as simple piping, it is very economical when there are many places to be removed.

In the fifth aspect of the invention, first, water is poured into the water tank from the mainstream water channel, but the upper water amount adjusting float valve adjusts the water in the water tank to a constant amount. However, since the water flow from this main waterway is uncertain, if the flow rate is insufficient, the lower water flow control float valve works to ensure a steady water supply by providing definite auxiliary water injection such as tap water. Became.

Finally, in the sixth aspect of the invention, snow absorbs infrared rays very well, so the snow melting effect is very high. The efficiency is very high because the fuel is not simply burned, but the engine is rotated to generate electricity and the heat burned by the engine is also used for melting snow.

Further, since the infrared lamp can irradiate infrared rays from any direction to any area without fixing it to one area, snow melting can be efficiently performed.
