The function of the present invention is as follows. Even if it doesn't snow unlike the conventional one, the water is raised to 11 ° C by using the midnight power. If there is snowfall the next morning and you want to melt the snow, throwing the snow into hot water at 11 ° C and activating the sprinkler 7 will shower the snow from above.
Next snow will be melted. Most of the snow will be melted in this process except heavy snow. The snow that became sherbet due to the influence of geothermal heat during the day will slowly melt and undergo secondary snow melting. At 11:00 pm, the temperature sensor works to start power supply at midnight, and if snow remains, current flows through the heat pipe to generate heat and melt snow, and the third snow melt is performed. Even after the snow melt, electricity will flow until the water temperature reaches 11 ° C.

This is approximately as follows with reference to FIG. The operating principle is that the cartridge heater 5A4 is incorporated in a part of the vacuum pipe 5A3 containing the hydraulic fluid 5A2.
Boiled, the steam 5A6 moves at high speed in the vacuum pipe,
The condensate 5A7 is repeatedly evaporated and condensed, and the temperature of the entire vacuum pipe becomes uniform in a short time. Vacuum pipe 5A3
Is made of carbon steel pipe, so it has very good thermal efficiency.

In this case, the cartridge heater 5A4 is detachably incorporated into the vacuum pipe 5A3 by pushing it into the vacuum pipe 5A3 and fixing it with a screw, and is adjustable from 300W to 200W. The lead cable 6 connected to each of the heat pipes 5A passes through the protective case 4 and is drawn out of the snow melting tank case as described above.

[0016]

Since the present invention is configured as described above, it has the following effects. A. When melting snow in a semi-solid state, the heat pipe can melt the same snow in 3/5 time as compared with the conventional method. This is because all the heat pipes in the parallel state heat as a surface. B. Since the water temperature is raised to a certain temperature in advance and showering is performed, it is sufficient to use only midnight power. Therefore, the running cost can be greatly reduced. That is, compared with the snowmelt power, the late-night power is 1/4 for the basic charge and 7/10 for the usage charge. Moreover, as a result of the hot water being poured from above the snow by the submersible pump 7A and stirring, the temperature difference of the water can be eliminated, so the heat generated can be effectively utilized for snow melting. C. Since the set temperature of the water temperature can be freely changed at the switchboard, the snow melting ability can be changed. D. Moreover, since the heat pipe is exposed on the upper surface of the bottom of the snow melting tank, it can be easily attached and detached. Since each heat pipe is an independent circuit of 300 W to 200 W, the output can be changed later by increasing or decreasing the number of heat pipes. As a result, the output can be changed with the same type.
