7. The use method of the device for taking the underground water heat is characterized by comprising the following steps:
the method comprises the following steps: firstly, a hot water pipe is placed at a geothermal well mouth, the bottom of the hot water pipe is communicated with an underground water pipeline, so that the internal hot water of the underground water pipeline is communicated to the inside of the hot water pipe, and the top of the hot water pipe is communicated to an underground water outlet pipeline;
step two: after the hot water pipe is installed, sliding the sliding sleeve at the bottom of the hot water pipe, further sliding the sliding sleeve towards the bottom of the hot water pipe, moving two pressure rods towards the geothermal well opening by a further connecting plate, enabling a clamping column to fall off from the inside of a limiting groove, enabling a spring to contract when the clamping column is abutted against the side wall of the hot water pipe, conveniently storing and reducing the occupied area before fixing a fixing plate, facilitating installation of the hot water pipe, stopping sliding the sliding sleeve when a clamping tooth at the bottom of the fixing plate is contacted with concrete at the edge of the geothermal well, further fixing a screw to a hole close to the sliding sleeve in a threaded connection mode, limiting the sliding sleeve, fixing a bolt to the concrete by penetrating through one end of the fixing plate, and fixing the bolt to the concrete to realize fixing of an integral structure;
step three: hot water flows into the hot water pipe from an underground water pipeline and then communicates the cold water with the inside of the water inlet pipe, the cold water is conveyed into the connecting ring inside the hot water pipe from the water inlet pipe, further cold water passes through the inside of four connecting pipes from the connecting ring, and then the preheated cold water is conveyed into a plurality of hot water plates with hexagonal prism-shaped structures from the four connecting pipes, water baffles are welded on the inner side walls of the hot water plates in an equidistant and staggered mode, the flow rate of the preheated water inside the hot water plates is reduced, the contact area between the water baffles and the geothermal water is increased by matching the hot water plates, the heat absorption efficiency is improved, and the welded plates welded at equal intervals on the side walls of the connecting rings are arranged in a staggered mode, so that the flow speed of the geothermal water is reduced, the flow rate of the geothermal water is reduced, the contact time between the geothermal water baffles is prolonged, and;
step four: when the water pipe is located, the other end of the water outlet pipe is communicated with the water storage device to store hot water after the water in the hot water plate flows to the inside of the water outlet pipe, the heat absorption plate which is of a wave-shaped structure and is arranged on the inner side wall of the hot water pipe is heated when the underground hot water in the hot water pipe flows, and the heat absorption plate is connected with the heat conduction pipe which is located on the surface of the water outlet pipe outside the hot water pipe, so that the heat preservation of the water in the water outlet pipe is realized.
