The present invention relates to a pipe device for groundwater and geothermal heat transfer, and more particularly, to provide a pipe device to more effectively raise the groundwater and geothermal heat of a constant temperature to the ground, in particular through the connecting means a plurality of pipes It is possible to connect and use it repeatedly, so that the inside of the groundwater hole can be cleaned periodically, and the maintenance of the facilities inside the facility is easy.In addition, the pipe has excellent corrosion resistance and water resistance, rust and scale In addition, it is to prevent the introduction of various foreign matters into the groundwater by means of the foreign matter injection prevention means, thereby significantly improving the quality and reliability of the product to allow consumers to plant a good image.

As is well known, groundwater [地下水; ground water is underground water with respect to surface water, and geothermal [地 熱; geothermy] refers to the amount of heat released from the inside of the earth to the outside through the surface. Geothermal heat is emitted from the entire surface of the earth to the outside. Higher value in the zone. The outflow methods are based on heat conduction, gas, hot water and volcanic eruptions. Geothermal energy is often used for power generation in places where there is a large amount of crustal heat, such as New Zealand, Italy and Japan. Geothermal heat is also based on the thermal energy generated by the natural collapse of radioactive materials in the earth's crust. On the other hand, heat is hardly released to the surface because the mantle is thermally insulated in the hot earth, where iron and nickel are melted. Appropriate use of the geothermal heat is quite advantageous in terms of environment. There is little carbon dioxide emissions and few pollutants. And geothermal heat can be used in many forms, including direct heating, power generation, heating and cooling through heat pumps, and heat for manufacturing.

The heat exchange structure using the groundwater and the geothermal heat as described above is conventionally used as shown in FIG.

In other words, in order to use the groundwater and geothermal heat with little temperature change throughout the year, the wells (3) and the pipes (1) are inserted into the rock, and the groundwater collected in the wells is pumped by an underwater pump (4) to exchange heat. After the heat exchange in (6), it is repeated to the inside of the well so as to be repeatedly circulated to maximize the heat exchange efficiency between the groundwater and the rock, and in winter the user by using the geothermal energy obtained by heat exchange with the groundwater in the rock In the summer, the heat generated in the user's room is radiated to the ground through the groundwater circulated (not shown in the drawing, 2 is a hole formed in the pipe, and 5 is a circulation pipe connected to the submersible pump and the heat exchanger). to be)

However, the above-described conventional technology has a problem in that the length of the pipe 1 is increased as the depth of the underground deepens, and the problem of installing a long pipe in the basement is very difficult and difficult. It became.

In addition, the conventional technology is excellent in corrosion resistance and water resistance, but because the pipe (1) is simply made of a material of PVC, but too weak to the strength, and foreign matter (rock and rock, sand grain, etc.) naturally occurring inside the groundwater hole In order to remove it, air surging should be carried out every two to three years. Therefore, the facilities (motor pump, pipe, motor cable, etc.) must be lifted and reinstalled. PVC pipe cannot be lifted and removed. There was a serious problem of not being able to.

In addition, the conventional technology has a problem that the groundwater is contaminated by the introduction of various foreign matters because there is no foreign matter input prevention device at the entrance of the underground well.

The present invention has been made in order to solve the above problems of the prior art, it is possible to use a plurality of pipes connected in succession through the connecting means repeatedly connected to the ground water and geothermal heat of a constant temperature more effectively to the ground The second purpose is to make it possible to use a plurality of pipes continuously and repeatedly through the connecting means, so that the inside of the groundwater can be periodically cleaned and the maintenance of the facilities inside The third purpose is to coat polyethylene, epoxy primer and modified polyethylene on the surface of the pipe of the pipe system, so that it has excellent corrosion resistance and water resistance, and has a significantly lower thermal conductivity than simple steel pipe. ), The fourth purpose is underground In order to prevent the introduction of foreign substances into the groundwater by providing the foreign material injection prevention means at the entrance, the fifth purpose is to improve the quality and reliability of the product and thereby to improve the quality and reliability of the groundwater and Provided is a pipe device for geothermal heat transfer.

In order to achieve the above object, the present invention provides a ground water and geothermal heat transfer pipe, the motor protection tube formed in a wide diameter so that the water pump is built-in; A plurality of pipes are installed consecutively at upper and lower ends of the motor protection pipe, and configured to lift and remove for maintenance of groundwater; And connection means installed between the motor protection tube and each pipe to maintain interconnection and airtightness.
