Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to a snow melting device (i.e., snow melting device) capable of efficiently melting snow in large quantities on roads, roofs, etc. in urban areas, and the structure thereof will be described in detail with reference to the accompanying drawings. Then, it is as follows.

Under the ground: Form a snow input tank (1) in a deeply immersed state.

The size of the snow dumping tank (1) is at least 2 to 3 inches high when viewed from the front, 1 to 3 inches wide, and 1 to 3 inches deep, but it varies depending on the burial location and amount of snow processed. It is possible to design.

The upper part of this snow charging tank (υ) has two openings (Mm) with a snow charging port (33) opened on the ground surface.

The opening/closing lid (2) shown in the drawings may be of a sealed type or a perforated type, and should preferably be treated with resin to prevent snow from adhering to it.

Further, the snow inlet (3) may be formed in one large location, or may be provided in several locations.

A drain pipe (4) is installed in the middle of the side of the snow dumping tank (υ) at a height that allows the desired amount of water to be stored, for example, at least 1 m or more above the bottom wall.

Install a supplementary water sprinkler (5) in the snow dumping tank (1)0
The water sprinkling device (5) in Figure jl1 is a water supply pipe (6), and is shown installed at the upper part of the negative side of the snow dumping tank (1).

g! &2° 3-factor watering device (51 is a watering pipe (7), which shows the case where it is arranged so as to be able to spray water over a wide area.

Furthermore, as shown in FIG. 3, a heating device using a heat pipe (8) may be provided below the two snow charging tanks (υ) to supply heat.

Alternatively, the snow charging tanks (1) may be arranged in parallel at appropriate intervals and communicated with each other through a communication pipe.

Figure 4 shows an example in which a snow dumping tank (1) is installed below the sidewalk, and the snow on the road is melted by sprinkling groundwater (same for rivers) pumped up from the well alJ from the watering nozzle aI on the road (9). Then, the lightning-extinguishing water is collected in a drainage ditch on the side of the road, and this collected water is used as supplementary water to be sprinkled from a water sprinkler (1 ton) (53), and a drainage pipe (4).
) is connected to a drainage earthen pipe buried underground. 〇 Also, by switching the pulp I, groundwater can be directly connected to the snow input tank (
1) You may sprinkle water inside.

For reference, the height of the experiment was 3m, width 2-5" * depth 2.5"
The amount of snow handled by @'s snow input tank in one winter is as follows◎ (4) Condition flow rate 100 no 4~300 no Replenishment water Water temperature 3℃ 0 throughput 2.16011'(11+1'/ Time check (2) Condition flow rate 80014 Make-up water temperature 8 to 10°C Processing amount 6.480 to 21,6001' (7 hours after 3 to 10)
Various conventional snow melting methods, especially road snow melting methods that sprinkle water on the road surface, and waterless snow melting methods that run hot water under the road surface or bury heat panels, have both initial cost and running costs. Because of this, it was not possible to install snow melting equipment on roads with frequent traffic, and snow fell from small alleys and roofs, and piles of snow in gardens and other areas were piled up! i: Special for 2 (: Snow melting equipment cannot be installed, so people have to manually remove snow from snow melting areas on roads, or use dump trucks or sieve trucks to transport snow to rivers or open spaces. The present invention solves these drawbacks, and as mentioned above, it is possible to inject snow while it is deeply immersed in the ground. An opening/closing lid (2) that forms a tank (1) and is provided at the top of this snow dumping tank (1)
The attached snow inlet (3) is opened on the ground, and the snow dumped from the roof or the lightning from the mansion can be removed from the snow inlet (3) using a snow dumper or snow shooter. If the snow is thrown in, the snow will be removed directly from the existing drainage main pipe.
It is possible to remove snow (secondary).

However, if the snow is left in the snow dumping tank (1), the snow cannot be smoothly drained to the main drainage pipe a field, but in this case, the present invention provides a drainage pipe (4) midway along the side of the snow dumping tank (1). Make sure that a certain amount of water is stored at the bottom of the snow dumping tank (1), and since the snow will be dumped into this water, the snow will melt more smoothly, and as it melts, the main drainage pipe will be drained. a3
This will result in H being mixed in.

Furthermore, since a sprinkler device (5) for make-up water was installed in the snow dumping tank (1), water sprinkler device 1 was installed on the snow poured into the snow dumping tank (1).
(If you replenish groundwater, heated water, river water, etc. from 5J, this replenishment water will melt the snow even better, and it will be the same as throwing snow into a river or pond, and it will flow smoothly into the main drainage pipe as it melts.) It will be discharged.

Since the snow throwing tank (1) of the present invention is formed in a state that is deeply immersed under the ground, the entire outer circumference of the snow throwing tank (1) is heated by geothermal heat ζ;
Since the snow is warmed even more, combined with the water injection by the water sprinkler (f5J), snow melting in the snow input tank (υ) is carried out extremely efficiently and quickly.

Snow melting water is not stored in the snow input tank (1), but excess snow melt water is drained as surplus water from the drain pipe (4), so there is always good snow melting in the snow input tank (1). In order to maintain the desired condition, the snow at the top of the snow inlet (3) is occasionally poked with a shovel or the like to drop it to the bottom.Snow can be melted efficiently and quickly by simply repeating the process of putting in new snow. Now, the large amount of snow that fell from roofs and the thunderstorms that piled up due to road snow removal will be gone before we know it, so we need to solve the trouble of removing snow (Second).

In addition, the water supplied from the sprinkler R (5) does not need to be in a large amount like when melting snow on a road surface, and only needs to be small enough to promote snow melting. There is no need to worry.

In addition, since the snow input port (3) is provided with an opening/closing function (23), it becomes a safe snow melting device that will not accidentally fall into the snow input tank (1) from the snow input port (3).

In addition, as shown in Fig. 4 of the facility for the snow input tank (1), existing equipment can be used, which reduces equipment costs, and since natural geothermal heat is used, there is no need for special maintenance equipment, reducing running costs. becomes unnecessary.

Furthermore, maintenance is only required once every 3 to 5 years, so the maintenance costs are lower than that of conventional snow melting equipment, and the maintenance work is extremely simple.
