DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pool and drainage of snowmelt water after snowmelt in a snowmelt chamber in a buried type snowmelt apparatus.

[0002]

2. Description of the Related Art Hitherto, a technique relating to a buried snow melting apparatus has been known. For example, JP-A-61-2
57515, JP-B-46-35541, JP-B-46-35542, and JP-A-62-2.
No. 58009, Japanese Unexamined Utility Model Publication No. Sho 62-129426, and Japanese Unexamined Patent Publication No. Sho 49-129327. As a conventional technique, a technique shown in FIG. 12 has been known for a snow melting machine that melts snow using a burner. That is, a snow melting tank 57 is provided on a traveling device consisting of a running wheel 55 and a sled 56, a snow melting tank 58 is provided in the snow melting tank 57, and a burner 59 is attached to a side portion of the snow melting tank 58. The hopper 60 is disposed on the top 57, and the snow input from the hopper 60 is melted in the snow melting tank 58 and discharged from the drain pipe 61.
62 is a fuel tank, 63 is a handle, 64 is an operation box, and 65 is a stand.

[0003]

However, in the above-mentioned conventional buried type snow melting apparatus, as disclosed in Japanese Patent Application Laid-Open No. 61-257515, the snow melting chamber and the hot air chamber are completely separated from each other in the vertical direction. It had a low thermal efficiency, such as melting snow, or had a configuration in which snow-melted water that had melted drips underground. Therefore, it is necessary to wait until the snowmelt water infiltrates the underground, and if the continuous snowmelt is not possible or the water surface of the sewer is higher than the buried position, there is a problem that the buried snowmelt device cannot be buried. It was. Further, the technology of Japanese Utility Model Publication No. 46-35541 and Japanese Utility Model Publication No. 46-35542 discloses a technique in which a plurality of pipes are used as snow melting cylinders in a snow melting chamber arranged on the ground to melt snow only by blowing hot air.
It is a method of pouring snowmelt water onto the ground, and it is not widely used due to the high snow input position, the large installation space for the equipment, and the necessity of storing it in a storage place except during winter. There was no.

[0004] Another conventional technique is to melt snow by domestic wastewater or to melt snow by heating temperature in a house.
The melting power of the snow was weak, and it was impossible to sufficiently melt the snow in a short time. The present invention, by burying the snow melting device in the ground, facilitates the introduction of snow into the snow melting tank, and also configures the passage of the snow melting water between the bottom of the snow melting cylinder and the bottom of the snow melting chamber,
A pool of snow-melting water is formed, the snow-melting water is introduced into a pump chamber formed at one corner of the snow-melting chamber, and is pumped by a submersible pump to be drained to a sewer. Further, the snow melting water passage is provided below the snow melting tube so that the snow melting water does not reach the burner and extinguish the fire.

[0005]

SUMMARY OF THE INVENTION The present invention is configured as follows to solve these problems. The snow melting room 1 except for an opening that can be opened and closed by the snow melting room lid 5
Is buried in the ground, a base 27 is placed in the snow melting chamber 1, and a long snow melting tube 26 is placed on the base 27 in a state of being floated in a horizontal direction. A burner chamber 29 in which the burner 12 is provided is provided, and the hot air discharge port of the burner 12 projecting from the burner chamber 29 in the direction of the snow melting chamber 1 communicates with the inside of the snow melting cylinder 26 so as to communicate with the lower surface of the snow melting cylinder 26 and the snow melting chamber. 1
The snowmelt water can pass through the bottom of the burner chamber.
29 below the snow melting chamber 1 on the opposite side to the bottom of the snow melting chamber 1.
The pump chamber 2 protrudes lower than
The submersible pump 3 is arranged in the
It is configured to enter .

[0006]

Next, the operation will be described. In the present invention, the upper part of the snow melting chamber 1 constitutes a space for snow melting with the snow melting cylinder 26, and the space between the bottom of the snow melting chamber 1 and the snow melting cylinder 26 is formed as a passage or pool of snow melting water. Therefore, when the snowmelt water is introduced in the direction of the submersible pump 3 in the pump chamber 2, it may hinder the movement of the snowmelt water, or may cause the burner 12 in the burner chamber 29.
The snow melt water had reached it, and fire extinguishing was no longer possible. Also, since the snowmelt water is pumped up by the submersible pump 3 and drained into the sewer, the snowmelt water is allowed to flow underground, or the snowmelt water overflows above the ground, as in a conventional snow-melting machine of the above-ground type, which freezes. That is no more.
