Description

[Detailed Description of the Invention] (Field of Industrial Application) This invention belongs to the field of heat exchange devices, and relates to a snow melting device that melts snow by spraying snow melting water onto the snow in a horizontal plane.

(Prior art) Conventional snow melting means for sprinkling water on the snow layer not only uses a large amount of snow melting water, but also melts only the snow in the areas that are hit by the snow melting water, and that area is used as a passageway for the snow melting water. However, the disadvantage is that the surrounding snow cannot be effectively melted, and if this watering method is used to flow snow melting water down from the ridge to melt snow that has accumulated on the roof, a particularly large amount of snow melting water is required. This made it uneconomical.

(Problems to be solved by the invention) The technical problem of this invention is to provide a snow melting device that efficiently melts snow accumulated on a roof.

(Means for Solving the Problems) In order to solve the above problems, this invention provides injection holes at required intervals on one side of the water pipe below the long snow stopper, and The above-mentioned injection hole is slidably and loosely mounted on the holding fitting with the injection hole facing the required elevation angle, and a drive device is installed in the water pipe to reciprocate in the axial direction beyond the distance between the injection holes, and the water for snow melting is applied to the eaves. This purpose is achieved by injecting it from the ground toward the ridge.

(Function) Snow melting water continuously and uniformly melts snow between layers of snow, and again melts snow at the joint surface between the lower surface of the snow and the roof surface.Moreover, since the snow melting water also participates in snow melting, the amount of snow melting water is extremely economical, and furthermore, The snow layer on the roof is melted sequentially starting from the eaves, so a large amount of snow does not fall all at once.

(Example) To specifically explain this invention with an example,
As shown in Fig. 1, injection holes 3 are arranged at intervals of 30 cm on one side (toward the ridge) of the water pipe 2 below the inverted L-shaped long snow stopper 1, that is, on the eaves side. , the water pipe 2 is slidably and loosely attached to the holding fitting 4 in a desired position so that the snow melting water injected from the injection hole 3 can jump over the snow stopper 1 in front and enter the snow layer at a predetermined angle. The water pipe 2 is reciprocated in the axial direction by a drive device 5 with a stroke of 30 cm or more, and a flexible hose 7 is connected to the water inlet 6 of the water pipe 2. The loosening means using the holding fitting 4 for the water pipe 2 and the reciprocating feeding means using the drive device 5 described above are generally known means.

The snow melting device a constructed in this way is placed on the eaves of the roof as shown in Fig. 2, and the snow melting water supplied from a water source not shown in the figure (ground water is more effective) is supplied to the hose 7. The water is guided and supplied to the water pipe 2, and is injected from each injection hole 3 all at once, and depending on the injection angle and the depth of the snow, the water is sprayed onto the snow or is sprayed into holes in the snow layer. At this time, the water pipe 2 reciprocates with a stroke greater than the interval between the injection holes 3, so the fountain sprays water continuously in a horizontal plane, and the snow layer is continuously and uniformly exchanged heat directly with the snow melting water to melt the snow. Moreover, the snow melting water that enters gradually loses its speed and becomes droplets and falls together with the snow melting water, and flows down the joint surface between the lower surface of the snow layer and the roof toward the eaves, so that the snow melting water thoroughly melts the snow. This means that heat exchange with the snow can be achieved with an extremely small amount of economical water. When the lower snow layer 8 is efficiently melted, the upper snow layer 9 falls, and this snow layer 9
When the snow is melted in the manner described above, the snow layer in the direction of the ridge (front) will slide down under its own weight and be stopped by the snow stopper 1, so choose a time when the outside temperature is relatively high and use the second
If snow melting operation is performed under the conditions shown in the figure, the snow layer on the roof can be sequentially melted at the eaves.

(Effect of the invention) As described above, according to the snow melting device a according to the invention, the injected snow melting water can continuously and uniformly melt snow over the required range between the snow layers without forming a fixed waterway. The snow layer falls like a "daruma drop" and the snow on the roof can be melted one by one at the eaves. Therefore, a large amount of snow can fall at once and cause problems with neighboring houses. Snow melting capacity is increased by achieving efficient heat exchange with a completely economical amount of water, and it is also economical in terms of power since snow melting can be performed with intermittent operation, and there is no impact on the watertightness of the roof top surface. Since the eaves are not left covered with snow for long periods of time, icicles do not form, and there is no risk of accidents caused by falling icicles, and there is no risk of slag leaking due to freezing. It has various effects.
