Description

[Detailed Description of the Invention] This invention relates to a non-sprinkling lightning extinguishing method, in particular a non-sprinkling lightning extinguishing method that artificially uses only the heat of groundwater to melt snow falling on roads and buildings, and returns the groundwater underground. It concerns the lightning method.

In recent years, the method of extinguishing lightning that has fallen on roads and buildings in snowy, cold regions by sprinkling groundwater has become widespread.
In this type of water-sprinkling lightning extinguishing method, the sprinkled groundwater melts the snow, but on the other hand, the water that flows down from roads and buildings into gutters directly flows into rivers and eventually into the ocean, gradually depleting local groundwater resources. Social issues such as land and land laws are becoming more serious.

This invention was developed with the aim of preventing such damage from occurring and completely melting snow on roads and buildings, thereby reducing economic and social activities during the winter in areas with heavy snowfall. This provides a non-sprinkling water lightning extinguishing method that can be used successfully.

According to this invention, the non-sprinkling water lightning extinguishing method involves storing hot water that absorbs solar heat in one well in the summer, pumping up the underground hot water from this well in the winter and placing it in a heat dissipation system buried in roads or buildings. After passing water through the pipes to melt the snow that falls on roads and buildings and to prevent freezing, the cold water is injected into the other well and the cold water is stored underground.In the summer, the cold water is poured into the other well. Water is pumped up from the well and passed through the pipes buried in roads and buildings, absorbing solar heat and turning it into hot water.
It is characterized by storing two.

Other objects, features, and advantages of the present invention will become apparent from the following detailed description along with the accompanying drawings, which illustrate one embodiment of the waterless lightning extinction method of the present invention.

1 and 2 of the drawings show an embodiment in which the waterless lightning extinguishing method of the present invention is applied to a road surface. As shown in the figure, in order to carry out the waterless lightning extinguishing method of the present invention, at least two wells are drilled 1.2 degrees deep underground.
The heat radiation and heat absorption pipes 4 are arranged in a meandering bent shape as shown in FIG. 1, or in parallel as shown in FIG.
Alternatively, it may be buried in an appropriate spiral or zigzag shape. Of course, the pipe 4 can be installed not only on the road surface but also in any place where lightning extinguishing is to be carried out, such as a building or the roadbed of a railway track. In this way, the road surface 5
A pipe 4 buried in an appropriate shape is connected to wells 1 and 2.
are connected to each other.

Therefore, by the combination of the wells 1 and 2 and the buried pipe 4 in this invention configured as described above, the pump 3 is connected to the well 1 into which hot water heated by absorbing solar heat is injected in the summer. If warm water is pumped up in winter, it is possible to pump groundwater that is much warmer (23°C to 25°C) than the normal temperature of groundwater in nature (approximately 12°C to 15°C). If water is passed through the pipes 4 for heat radiation and heat absorption buried under the road surface 5, the heat of the hot water will be transferred to the road surface 5, and the snow that falls on the surface of the road surface 5 or buildings will be melted one after another. It can also prevent freezing and improve road surface 5.
It can effectively extinguish snow falling on buildings.

After the lightning has been extinguished in this way, the cold water is injected deep underground into the other well 2. This cold water injected into the well 2 after lightning extinguishes is injected deep underground to create a cold water zone 8 in an aquifer deeper underground than the impermeable layer 6, thereby preventing wastage or contamination of precious groundwater.

Furthermore, in the summer, if groundwater is pumped up from the cold water zone injected into this well 2, the temperature will be lower (7°C to 10°C) than the normal temperature of groundwater in nature (approximately 12°C to 15°C).
By passing this underground water through pipes 4 buried in the road surface 5 and buildings, the road surface 5 and the buildings absorb solar heat and become warm water, which is then heated to the road surface 5. It can also be used to prevent water from softening and to cool buildings.If this hot water is then injected deep underground through the well 1 without exposing it to the outside air, a warm water zone 7 will be formed in the aquifer below the impermeable layer 6. However, solar heat can be stored underground, and this hot water can then be pumped up again in the winter and used to melt snow, as described above.

Further, although the drawing shows an embodiment in the winter season, it is also possible to provide a pump for pumping water in the well 2 in the summer season in advance so that both pumps can be used by switching.

In this way, according to the non-dispersion water lightning extinguishing method of the present invention, hot water heated by absorbing solar heat in the summer is stored deep in one well, and the underground hot water from this well is pumped up in the winter to clean the road surface. After passing water through pipes buried in buildings to melt snow on roads and buildings and prevent freezing, this cold water is injected deep underground into another well and stored, and this cold water is used in the summer. Water is pumped up and passed in the opposite direction through pipes buried in roads or buildings, absorbing solar heat, turning it into hot water and storing it deep underground in wells. This method uses less water than the conventional method of water lightning suppression. It has a good lightning extinguishing effect, does not spray water on roads or buildings, and does not expose it to the outside air, so the cold water after extinguishing lightning can be injected deep underground using an injection well. A cold water zone can be formed in an aquifer without wasting or contaminating precious groundwater.
