It looks like this.

Further, on the frame 9, there is a burner 2 and a fuel tank 13 as a fluid supply device 11 that generates and supplies heating fluid.
is provided.

As shown in FIG. 4, the burner 2 is provided with a horizontal combustion tube 15 inside an outer cylinder 14, and an annular gas manifold 16 is disposed at the base of the combustion tube 15. A nozzle hole 17 is provided around the tip side, and the fuel tank 13 is provided in the gas manifold 16.
are connected to each other via a gas pipe 18, and a pyro sotonoux 19 is provided in the center of the gas manifold 16. Further, a fan casing 20 is formed at the base end of the combustion tube 15, and a fan 21 is rotatably provided within the fan casing 20. In addition, the outer cylinder 15
One end of a guide tube 21 made of a heat insulating material that guides heating fluid is detachably connected to the tip of the combustion tube 15 covered with It is detachably connected to one end of the snow blowing pipe 1 via the snow blowing pipe 1. Further, the fuel tank 13 is fixed on the frame 9, and the fuel tank 13 is fixed on the frame 9.
The burner 2 is fixed to the upper part of the burner 2 via a supporting frame 22 fixed to the frame 9.

It is becoming more and more common. In addition,
In the figure, 23 is a handle attached to the rear part of the frame 9.

Next, lightning extinguishing work will be explained.

f During the snow season, as shown in FIG. 1, for example, the snow blowing pipe 1 is laid in a snow collecting area on a road surface or a snow extinguishing area such as a snow falling area with each heated fluid outlet 5 facing upward. Then, the collected snow A is piled up on top of the snow-blowing pipe 1 so as to bury the snow-blowing pipe 1 therein. In this state, the moving vehicle body 8 is moved and the guide pipe 21 of the fluid supply device 11 is connected to one end of the snow blowing pipe 1 via the connector 6.

At this time, when the burner 12 of the fluid supply device 11 is activated and the hot air generated as a heated fluid is supplied into the through hole 4 of the snow blowing pipe 1 through the guide pipe 21, this hot air is communicated with the through hole 4. The heated fluid is ejected outward from the large number of heated fluid blow-off holes 5, and the snow accumulated on the snow blowing pipe 1 is melted by the lightning extinguishing action due to the heat of the hot air.

In this case, since the through hole 4 of the snow blowing pipe is formed of the cylindrical pipe 3 made of a heat insulating material, the hot air supplied into the through hole 4 is reduced by the outside temperature due to its insulation effect. The heated fluid is ejected from each of the heated fluid blowing holes 5 without any heating, and the snow is melted with high thermal efficiency.

Next, in the embodiment described above, the case where the snow-blowing pipes 1 are arranged in one main river is explained, but the present invention is not limited to this. For example, as shown in FIG. 5, a plurality of snow-blowing pipes 1 are arranged in parallel, It may be formed into a U-shape or a U-shape. In this case, each snow-blowing pipe 1 and a heat conduction base pipe 24 in which each snow-blowing pipe 1 is connected
has the same structure as in the previous embodiment.

Further, in each of the embodiments described above, a case has been described in which hot air from the burner 12 is supplied as the heating fluid to the snow blowing pipe 1, but the present invention is not limited to this, and a boiler may be used as the fluid supply device.
The steam generated from this may be supplied into the snow extinguishing pipe 1 as a heating fluid.

Further, in each of the embodiments described above, the case where the snow-blowing pipe 1 is used as a stationary type installed in a snow-blowing section is explained, but the snow-blowing pipe 1 is not limited to this, and the snow-blowing pipe 1 can be used as a fluid supply device 11 (including the case of a boiler). As the moving vehicle body 8 moves forward, the snow blowing pipe 1 is inserted into snow that has fallen or collected, and the heated fluid blowing holes 5 of the snow blowing pipe 1 are fixed in communication with each other. It may also be used as a self-propelled mobile type that blows out heated fluid to melt snow, as in the case of each of the above embodiments.

〔Effect of the invention〕

According to the present invention, by using a snow blowing pipe that spouts a heated fluid for extinguishing lightning, the snow blowing pipe can be easily installed in a snow melting section such as a snow collecting section, and Snow around the snow pipe can be easily and reliably melted by ejecting heated fluid from each heated fluid outlet of the snow pipe, reducing the equipment and maintenance costs of conventional road heating methods. It is extremely economical as it eliminates the need for lightning, and it is also easy to move and install, making it ideal for lightning extinguishing work at entrances and exits of stores in urban areas, roads in shopping streets, sidewalks, parking lots, etc. .
