Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a snow melting device for processing snow that has fallen and accumulated in snowy areas.

The issue of snow disposal is an extremely important concern for people living in areas with heavy snowfall, but due to various reasons such as the rise in land prices in urban areas and surrounding areas, people living in these areas are especially concerned about the accumulation of snow in their own houses and gardens. It was difficult to dispose of accumulated snow within one's own premises, and sometimes problems even occurred with neighbors over snow disposal.

For this reason, bathtub-style snow melting devices that use kerosene as a heat source, and devices that use underground water or seawater to melt snow by installing snow melting channels have been developed, but these devices are extremely disadvantageous in terms of cost and maintenance. Therefore, the reality is that it has not yet become widespread.

Therefore, snow melting is an easy and inexpensive way to dispose of snow that has accumulated on roofs, etc., as well as snow that has accumulated in front of entrances and gardens, or snow that has been removed from roads and piled up on individual premises. The provision of such equipment was widely desired by consumers.

The present invention has been made in view of this situation, and involves putting snow into a snow melting tank installed in the depth direction of the ground, and pouring geothermally heated water at the bottom of the snow melting tank onto the snow. Alternatively, the above-mentioned conventional problems are attempted to be solved by providing a snow melting device configured to pump up household wastewater (wastewater from a bathtub and kitchen) and sprinkle water.

An embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

The figure shows a cylindrical hole, for example, about 1 m in diameter and about 3 m deep, installed in the garden of an ordinary house, in the depth direction, and filled with concrete, FRP (fiber reinforced resin), etc. This figure shows a snow melting device A in which a snow melting tank 1 is embedded in the upper opening and has a lid 1a that can be freely opened and closed.

To explain in detail, a water storage section 2 is provided at the bottom of the snow melting tank 1,
An appropriate amount of water that is heated to approximately 7 to 10 degrees Celsius by geothermal heat is stored. In addition, a pump 3 for pumping up water from the water storage section 2 is disposed in the upper part of the snow melting tank 1, and the water is stored in the water storage section 2 with one end opened in the water storage section 2 and the other end connected to the inlet side of the pump 3. A pumping pipe 4 that guides the water to the upper part and a pump 3 communicate with the pumping pipe 4, and the pumped water in the water storage section 2 is transferred to the upper water spout 5a and the lower water spout 5.
A water sprinkling device is provided, which is comprised of a water sprinkling pipe 5 that guides the water pipe 5 to Further, a pipe 11 is connected to a middle part of the pumping pipe 4, and is connected to a tank (not shown) for storing domestic wastewater discharged from the kitchen, etc., and a switching pulp 12 is provided at the connecting part. There is. Further, this water sprinkling pipe 5(3) is provided with an opening/closing pulp 7a. Moreover, the drainage vibro is branched from the water sprinkling pipe 5 to the outside of the snow melting tank 1 and guided to the sewer. 7b is an opening/closing pulp provided in the drainage vibro.

Incidentally, since the dirt contained in the stored water settles on the bottom wall of the water storage section 2, in order to prevent this dirt and the like from clogging the opening at the tip of the pumping pipe 4, a A partition @1b is provided in a protruding manner, and a filter 8 for preventing dust from flowing into the pumping pipe 4 is similarly provided at the upper end of the partition wall 1b.

Further, reference numeral 9 indicates a ladder arranged in a row on the side wall of the snow melting tank 1, and 10 indicates a grid made of steel, for example, installed inside near the upper opening of the snow melting tank 1, and is used to prevent children from falling into the tank 1. It functions as a crusher for the snowpack that is thrown into the ground.

Next, the operation of the snow melting device A having such a configuration will be explained. □ When using it for the first time, first inject it into the water storage part 2.
Over time, this water is heated to approximately 7 to 10 degrees Celsius by geothermal heat. After this, the lid 1a of the snow melting tank 1
Open the tank and dump the snow that has accumulated on the premises etc. into tank 1. This snow passes through the grid 10 and accumulates in the tank 1, although some of it melts with the stored water. Then, the pump 3 is operated to pump up water warmed by the geothermal heat in the water storage section 2, and water is sprinkled on the accumulated snow from the respective water sprinkling ports 5a, 5, and 5b to melt the snow.

Furthermore, when domestic wastewater is used as water for snow melting, the pipe 11 and the pump 3 may be communicated with each other by switching the switching valve 12.

At this time, the snowflakes that did not fall from the grid 10 are also turned into sherbet-like by the water from the upper water sprinkling port 5a.
The snow falls smoothly into the tank 1 and is gradually melted, especially by water sprinkling from the lower water sprinkling port 5b.

Then, when the amount of water in tank 1 increases, start watering (evening 5).
Close the opening/closing pulp 7a on the side and open the opening/closing pulp 7b on the drainage vibro side to guide the pumped water to the drain pipe 6.
The amount of water in the tank 1 is adjusted by draining the water into a sewer (not shown).

In this way, snow melting equipment that uses geothermal heat can be manufactured with a relatively simple configuration, which eliminates the disadvantages in terms of maintenance and management of equipment that uses conventional kerosene, etc., and also provides energy-saving effects. The production cost can also be reduced.

Furthermore, since this device is installed underground in the depth direction, it does not require much land for installation, which is advantageous in terms of cost. Therefore, from the viewpoint of effective land use, it is more effective to install this device under the floor of a building. Furthermore, by providing this device integrally with the foundation of the building itself, efficiency is further increased in terms of cost and the ability to utilize household waste heat.

Note that the pump 3 according to this embodiment is reversible,
Moreover, if the upper water sprinkling port 5a is configured to be connectable to an external water pipe, clogging of the filter 8 can be easily removed and cleaning efficiency can be improved.

If the floor of the room for storing pump 3 is left partially open...
It is clear that not only can air be supplied into the tank 1, but also the heat of the motor of the pump 3 can be used, and the snow melting effect can be enhanced.

Furthermore, if the upper outer periphery of the snow melting tank 1 is surrounded by a mound of earth as shown in the figure, the heat retention effect within the tank 1 can be enhanced and the snow melting efficiency can be increased.

Then, a pipe for circulating the water in the tank may be installed in the ground around the outer circumference of the snow melting tank to serve as an auxiliary heat exchanger and warm the circulating water with geothermal heat. Effective use of geothermal heat can be achieved.

Alternatively, instead of using a circulation pipe as an auxiliary heat exchanger, one end of a heat pipe may be installed inside the snow melting tank, and the other end may be installed underground, so that geothermal heat can be absorbed into the snow melting tank via the heat pipe. good.

As explained above, according to the present invention, a snow melting tank is provided underground in the depth direction, and the snow put in the tank is watered using geothermally heated water or domestic wastewater. With this configuration, the manufacturing cost of the device itself, the installation space, and the cumulative cost of maintaining and managing the device can be kept low. It is also possible to obtain an energy saving effect.
