An apparatus for guide, cleaning and protection of a standing column well (SCW) type geothermal heat exchanging circulation pipe is inserted into the standing column well in the vertical direction. The apparatus for guide, cleaning and protection of the standing column well (SCW) type geothermal heat exchanging circulation pipe comprises multiple small inflow holes at the bottom part to allow the inflow of underground water; an intake pipe having a water course inside to transport the water exchanged heat with the earth to the ground; a heat exchanger connected to one end of the intake pipe to be supplied with water pumped up by a deep-well pump to perform heat exchange; a discharge pipe connected to one end of the heat exchanger and inserted into the standing well column in the vertical direction to discharge the water exchanged heat with the earth through the heat exchanger into the ground through a water course formed inside; a U-shaped guide pipe mounted at the other end of the intake pipe and of the discharge pipe to connect the intake pipe and the discharge pipe; spacing parts installed at a distance from each other along the intake pipe and discharge pipe in the vertical direction to keep a distance between the intake pipe and the discharge pipe; a connection pipe placed between the bottom part of the intake pipe and discharge pipe and the guide pipe to transport the water exchanged heat and discharged from the discharge pipe into the intake pipe; and a check valve mounted inside the intake pipe. The check valve is opened and closed to transport the water exchanged heat with the earth in one direction, and the guide pipe forms a water course inside and a guide member having a stop groove on the outer surface. |
