Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a snow melting tank that can efficiently melt snow that has been removed or removed, and can effectively promote snow disposal in snowy regions.

(Prior art) As is well known, in snowy regions, snow removal and disposal of removed snow are problems, but especially in areas with a large number of houses in areas with heavy snowfall, it is difficult to remove snow and dispose of removed snow. Unable to secure a place to store the snow, they have to load it onto a truck and transport it to a remote dumping site, or pile it up high around their house, which takes a lot of time and effort, and is not economically viable. The current situation is that they are suffering huge losses.

(Problems to be Solved by the Invention) As described above, conventional methods have a problem in that it is extremely difficult to remove snow and treat the removed snow.

Therefore, this invention was made in consideration of the above circumstances, and is capable of efficiently melting and extinguishing snow that has been plowed or removed, is economically advantageous, and is an effective way to dispose of snow in snowy regions. It is an object of the present invention to provide an extremely good water tank for snow melting that can promote snow melting.

(Means for Solving the Problems) A snow melting water tank according to the present invention includes: a drainage tank having a drainage port formed on a side surface, a snow melting tank in which the lower part of the drainage tank is connected to the snow melting tank and the upper part thereof is open; It is equipped with a heat generator installed in the tank.

(Function) According to the snow melting tank configured as described above, when snow is poured into the snow melting tank through the upper opening, the snow is melted by the warm water in the snow melting tank. At this time, the water level in the snow tank is determined by the height of the drain outlet of the drain tank, so excess snowmelt water can flow down from the drain outlet of the drain tank and be discharged into drainage channels, etc. can.

Therefore, it is possible to efficiently melt and eliminate snow that has been removed or shoveled, which is economically advantageous, and can effectively promote snow removal in snowy regions.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings. That is, FIG. 1 schematically shows the embodiment described here, in which an aquarium main body 11 is buried underground E, and a lid 12 provided at the upper part of the aquarium main body 11 in the figure is opened. Thus, the snow shovel operator A can throw the removed snow S into the water tank body 11.

Hot water W is poured into the water tank body 11, and the hot water W is maintained at a predetermined temperature by an electric heater 18 installed in the water tank body 11. For this reason, the aquarium body 1
The snow S thrown into the tank 1 is melted by the warm water W and disappears as water.

At the knee, a drain port 15 communicating with a drain channel 14 is provided on the side surface of the water tank body 11. For this reason, hot water W
The excess snowmelt water is overflowed through the drain 15 and discharged into the drain 14, where the snow melting process is performed.

FIGS. 2(a) and 2(b) each show the detailed structure of the water tank body 11. That is, this aquarium main body 11
is formed into a cylindrical shape with a bottom from a material that has water-blocking and heat-insulating properties. It is buried in E.

Furthermore, the inside of this water tank body 11 is divided into two parts in the vertical direction in FIG. It is formed. However, the partition plate 1B does not reach the bottom of the water tank body 11, and the snow melting tank 17 and the drainage tank 1
8, its lower comrades are connected.

The electric heater 13 is installed underwater in the water tank body 11 constituting the snow melting tank 17, and the water tank body 1
A water level gauge 19 and a water temperature gauge 20 are installed along the inner surface of the wall 1 above the electric heater 13, respectively.

These electric heaters13. The water level gauge 19 and the water temperature gauge 20 are the second
It is connected to an operation control panel 22 installed on the ground via a cable 21 indicated by a dotted line in Figure (b) to be controlled.

Further, a water level mark 23 is attached to the inner wall surface of the water tank body 11 constituting the snow melting tank 17. Furthermore, the upper open end of the snow melting tank 17 is covered with a fall prevention device 24 made of a coarse grid, wire mesh, etc., to prevent humans, animals, etc. from accidentally falling into the snow melting tank 17. has been done.

On the other hand, the above-mentioned drain port 15 is formed on the side wall of the water tank body 11 constituting the water tank 18 at a position close to the water level mark 23 of the water tank body 11.

Here, the lid 12 is provided at the upper open end of the aquarium main body 11, as described above. This lid 12
As shown in the figure, there is a snow melting tank lid 12a that is formed in a disc shape that follows the shape of the upper opening end of the water tank body 11 and can close the upper opening end of the snow melting tank 17, and an upper part of the drainage tank 18. It is separated into a drain tank lid part 12b that closes the opening end.

And these snow melting tank lid part 12a and drainage tank lid part 12
b is rotatably connected by opening/closing fittings 25.25, and only the drain tank cover 12b is fixed to the upper open end of the drain tank 18, so that the snow melting tank cover 12a is As shown in FIG. 4, it is rotated in the directions of arrows A and B, and the upper open end of the snow melting tank 17 comes to be opened and closed.

Here, first, the snow shoveling worker opens the snow melting tank lid 12a and pours water into the snow melting tank 17. In this case, since the lower portions of the snow melting tank 17 and the drainage tank 18 are connected to each other, the water levels of the snow melting tank 1117 and the drainage tank 18 rise at the same level. Then, the water level is at the drain port 15 of the drain tank 18.
When the water reaches this point, the excess water injected beyond that point flows down to the aforementioned drain 14 through the drain 15.
The water level will no longer rise. The water level mark 23 indicates the level at which the water level will no longer rise, and for this purpose, the snow shovel operator only has to inject water up to the level indicated by the water level mark 23.

Next, the injected water is controlled by an electric heater 13 to a predetermined temperature that can be set arbitrarily. This control is performed by automatically controlling the amount of heat generated by the electric heater 13 using the operation control panel 22 based on the detection output of the water thermometer 20. However, since the water thermometer 20 is installed in the water above the electric heater 13, the water temperature of the upper water is controlled to be a predetermined temperature.

Note that the operation control panel 22 operates to automatically stop driving the electric heater 13 based on the detection output of the water level gauge 19 when the water level has not reached the level indicated by the water level mark 23. .

Thereafter, during snow shoveling work, the removed snow is put into the snow melting tank 17. Then, the thrown snow stays in the vicinity of the water surface of the water stored in the snow melting tank 17, that is, in the warm water portion with the lowest density, and is quickly and efficiently melted.

Since the temperature of water is highest at 4°C, this cold snowmelt water, that is, excess snowmelt water, is stored in the snowmelting tank 1.
7, the water flows down through the drainage port 15 and is discharged into the drainage channel 14.

! According to the configuration of the above embodiment, the snow that has been removed or shoveled can be efficiently melted and disappeared, so there is no need for a storage area or dumping area for snow, and the labor required for snow disposal is reduced. One hour and cost can be saved, and snow removal in snowy regions can be effectively promoted.

In addition, it takes advantage of the property that snow quickly and efficiently melts into water with warm water, and also takes advantage of the physical properties of water, making it possible to use energy efficiently and prevent energy wastage. This is also an economic advantage.

Furthermore, in areas with heavy snowfall, snow acts as a heat insulator, so by burying the water tank body 11 underground, the water stored in the water tank body 11 can be prevented from freezing without using the electric heater 13. You can expect the effect of

Moreover, since the partition plate 1B is deeply submerged in the water stored in the water tank body 11, it is possible to prevent cold air from entering from the drain port 15 side. Furthermore, the aquarium main body 11 is not limited to being buried underground, but may also be installed on the floor or on a pedestal.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and can be implemented with various modifications without departing from the gist thereof.

(Effects of the Invention) As detailed above, according to the present invention, snow that has been removed or shoveled can be efficiently melted and eliminated, which is economically advantageous and makes snow removal effective in snowy regions. It is possible to provide an extremely good snow melting tank that can promote snow melting.
