Description

The present invention relates to a snow melting device for melting snow piled up on a site.

In heavy snowfall areas, snow removal work (snow treatment measures) is being carried out to ensure traffic safety during the winter. For example, leaving snow on a residential site on the road delays the snow removal work and is a dangerous act in terms of traffic safety. Therefore, it is necessary to bring the snow on the premises to the designated snow dump.
However, there is a problem that it takes labor and costs such as transportation cost to bring snow into the snow dump.

Therefore, conventionally, a snow melting treatment device capable of suppressing the cost has been provided (for example, Patent Document 1).

The present invention realizes facilitating snow shoveling work on the premises.

The snow melting device of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing the structure of the snow melting device of the present invention. FIG. 2 is a diagram showing a comparative example of the snow melting device of FIG.
The snow melting device of the present invention is provided with a hot water storage tank for inserting snow and two drain pipes having different heights in the hot water storage tank, and limits the amount of water flowing into the drain pipe at a low position.
The snow melting device 10 of FIG. 1 includes a hot water storage tank 14 for charging snow 12 and two drainage ports 16 and 18 having different heights on the side surfaces of the hot water storage tank 14, and hot water storage is provided in each of the drainage ports 16 and 18. Drainage pipes 20 and 22 are connected to the inside of the tank 14. The drain pipes 20 and 22 connected to the drain ports 16 and 18 are provided so as to have different heights. In FIG. 1, the drainage pipe 20 connected to the drainage port 16 at a high position is provided at a position higher than the drainage pipe 22 connected to the drainage port 18 at a low position.
The water storage 14a in the hot water storage tank 14 to be drained is discharged to the outside (drainage groove 24) through the drainage pipes 20 and 22. Further, the tip openings 20a and 22a of the drain pipes 20 and 22 in the hot water storage tank 14 are arranged at positions lower than the drain ports 16 and 18.

The hot water storage tank 14 is provided with an openable / closable lid 14b on the ground surface 26, which is an inlet for snow 12, and the tank body 14c is embedded in the ground 28. A pipe 30a of the heat pump 30 is laid at the bottom of the hot water storage tank 14, so that the water storage 14a in the hot water storage tank 14 can be used as hot water. Further, it is assumed that the back surface of the lid 14b of the hot water storage tank 14 and the inner wall of the tank body 14c are covered with a heat insulating material (not shown).
The operating time of the heat pump 30 is the midnight power usage time zone. As a result, the running cost can be reduced. The water storage 14a of the hot water storage tank 14 can be heated to about 40 ° C. by using midnight electricity. Further, the sound emitted from the heat pump 30 during operation is about 40 dB to 45 dB, and there is no noise trouble.
In the present invention, it is assumed that the water storage 14a cannot be heated during the snow melting operation (time zone when electricity cannot be used at midnight).

Two drain pipes 20 and 22 having different heights are provided in the hot water storage tank 14. Further, the amount of water flowing into the drainage pipe 22 at a low position is limited. In FIG. 1, the tip opening 22a of the drainage pipe 22 at a low position is closed by a lid 32 provided with a plurality of small holes. The amount of water flowing into the tip opening 22a of the drain pipe 22 is limited. Therefore, even if the water level in the hot water storage tank 14 increases with the introduction of the snow 12, the drainage pipe 22 at a low position does not drain the water. Even if it is drained, the amount of water is small.
The hot water 14a in the hot water storage tank 14 before the snow 12 is thrown in is stored up to the position of the drainage port 18 connecting the drainage pipe 22 at a low position.

The snow melting device 34 of FIG. 2 includes one drain pipe 34a in the hot water storage tank 14. The hot water 14a in the hot water storage tank 14 before the snow 12 is put in is stored up to the position of the drainage port 34b connecting the drainage pipe 34a. In the snow melting device 34 of FIG. 2, when the snow 12 is thrown in, the water level in the hot water storage tank 14 rises, and at the same time, the hot water 14a in the hot water storage tank 14 is drained to the outside (drainage groove 24) through the drain pipe 34a. Therefore, since the hot water 14a in the hot water storage tank 14 is drained before the snow 12 to be introduced melts in the hot water storage tank 14, the snow melting ability of the snow melting device 34 before the snow 12 is charged cannot be sufficiently exhibited. Since the constituent parts having the same reference numbers as those in FIG. 1 are the same as the constituent parts in FIG. 1, detailed description thereof will be omitted.
On the other hand, in the snow melting device 10 of FIG. 1, even if the water level in the hot water storage tank 14 rises when the snow 12 is thrown in, the time for the water level to rise to the position of the drain port 16 to which the drain pipe 20 at a high position is connected. In T, the hot water 14a in the hot water storage tank 14 is not drained to the outside (drainage ditch 24) through the drain pipe 22 at a low position, and even if it is discharged, the amount of water is small. That is, a time lag T (time difference) occurs between the introduction and drainage of the snow 12. Therefore, the time T until the water level rises to the drain pipe 20 at a high position can be used for melting snow without wasting the hot water 14a in the hot water storage tank 14. By generating a time lag T (time difference) between the introduction and drainage of the snow 12 in this way, it is possible to prevent a decrease in the snow melting ability of the snow melting device 10 and to melt the snow to be introduced without spending time.
Further, since the heat pump 30 is not operating during the snow melting work, no noise is generated during the work.

FIG. 3 is a diagram showing another embodiment of the snow melting device of the present invention. The snow melting device 36 of FIG. 3 is a hot water storage tank 14 in which a drain pipe connected to a drain port 38 in which the drain ports 16 and 18 of the snow melting device 10 of FIG. 1 are combined is branched. The two drainage pipes 40 and 42 branched in the hot water storage tank 14 are provided so as to have different heights. Further, the amount of water flowing into the drainage pipe 42 at a low position is limited. Similar to the snow melting device 10 of FIG. 1, the tip opening 42a of the drainage pipe 42 at a low position is closed by a lid 32 provided with a plurality of small holes. The amount of water flowing into the tip opening 42a of the drain pipe 42 is limited. Therefore, even if the water level in the hot water storage tank 14 increases with the introduction of the snow 12, the water is not drained from the drain pipe 42 at a low position. Even if it is drained, the amount of water is small. As a result, a time lag T can be generated between the introduction and drainage of the snow 12, the decrease in the snow melting ability of the snow melting device 36 can be prevented, and the snow to be introduced can be melted without taking time.
The hot water 14a in the hot water storage tank 14 before the snow 12 is thrown in is stored up to the position of the drain port 38 connecting the drain pipe 42 at a low position. Further, the water storage 14a in the hot water storage tank 14 to be drained is discharged to the outside (drainage groove 24) through the drainage pipes 40 and 42. The tip openings 40a and 42a of the drain pipes 40 and 42 in the hot water storage tank 14 are arranged at positions lower than the drain port 38.
Other than the above, it is the same as the snow melting device 10 of FIG. 1, and therefore detailed description thereof will be omitted.

The snow melting device of the present invention is suitable for installation in a site such as a house. Rather than melting a lot of snow at once, for example, by melting snow little by little every day, you can bring it to the snow dump, eliminate the pile of snow on the premises, and live a safe and effortless daily life in a snowy country. It is possible by the present invention to make it possible.
