Description

[Detailed Description of the Invention] 1. Purpose of the Invention The present invention creates an artificially shallow aquifer, stores solar heat in the summer and mid-season by circulating high-quality water, and melts snow without watering in the winter. roof as a water source and heat source.
This relates to a method used for melting snow on roads, etc.

Previously, there was a method of storing solar heat in the soil during the summer and mid-season, but it was based on the use of well water from deep aquifers, and it was difficult to bring the temperature of the pumped water close to the temperature of the aquarium water. There are also water quality issues.

This cannot be said to be possible anywhere. Furthermore, the efficiency of heat storage was low due to the movement of groundwater.

1) By storing water and heat in an artificial shallow aquifer and using it for circulation, the present invention is not limited by the geological strata of the location, is not subject to restrictions on water quality, and the power required for the water @ ring can be adjusted to the depth of the water. It can be made shallower, making it several minutes smaller than a deep well, and has no negative impact on ground subsidence or general groundwater.

The purpose is to provide a circulating water source for non-sprinkling snow melting.

2. Structure of the Invention The present invention stores the heat required for winter snow melting in an artificial aquifer. 1. A pump installed in one corner of the artificial aquifer, a non-sprinkling snow melting pipe directly connected to the pump, and a water intake system. It is constructed by providing an opening for inflowing water after surface heat exchange at a location away from the pump. Pumps are operated to the minimum necessary, and all of the pumped water is returned to the artificial aquifer through non-sprinkling snow melting pipes, thus forming a complete cycle and never losing weight. By cultivating water that has been heated to 25°C or higher during the summer/mid-season, it is possible to heat and store heat in and around the tank over a long period of time to a ground temperature close to 25°C. Since the free water level of the aquifer is shallow, the power required for the pump is only a few minutes compared to a normal deep well pump.

An embodiment will be described with reference to the drawings. Figure 1 is an elevational sectional view explaining the outline of the configuration, and one artificial diaphragm W# membrane is installed underground so that the internal volume is large enough to cover the required amount of W heat and the cross section is as shown in the figure. . Two pieces of sand are placed at the bottom to create a structure that allows excess water to permeate underground. 1. The artificial isolation membrane has a paddy field structure, and the inside is filled with sand and stone through a cushioning material.

3 A well tube and 5 baffle plates are built into the sand stone. 4
The well cylinder has an appropriate water intake hole or water intake slit, and six pumps are placed inside. The water discharged from the pump 6 passes through the pipe to the branch 7, passes through the ground heat exchange section 8, and returns to the tank through the water outlet 9. Since that amount of water is passed through in a nearly sealed state, 100% of the water is returned without being contaminated.

9 Water that enters the tank from the water outlet exchanges heat with crushed stone,
5 Evil W4 Cross the gap between the boards and return to 6 pump. The water level is almost always maintained at the two ends of the isolation membrane J, and when the amount of water increases due to inflow of rainwater, etc., it passes through the permeation membrane or pipe installed on the outside of the artificial isolation membrane and flows through the two ends of the bottom surface of the artificial isolation membrane.
It is guided by the sand and penetrates underground. Figure 2 is a diagram explaining the state of change in soil temperature, and shows the initial stage of snow melting, for example, around 12 p.m.
The temperature state at the end of the month is shown by the solid line 11, the temperature state at the middle of the snow melting season, for example, late January, is shown by the point l@12, and the temperature state at the end of the snow melting season, for example, late February, is shown by the chain line 3. show,
The vertical axis represents the temperature, and the horizontal axis represents the distance from the pumping position 6 toward the water outlet 9.

3゜Effects of the Invention The present invention locally circulates and uses a certain amount of water regardless of the groundwater, so it has the advantage of being able to ignore the effect on general deep groundwater, and effectively stores and uses solar heat during the summer and intermediate seasons. Therefore, there is no need for artificial heating. Compared to water-sprinkling snow melting, the required power can be reduced to a few minutes because a deep well pump is not used, and since there is no concern about water quality, it can be operated almost maintenance-free, and its economic effects are enormous.
