Description
Technical Field

Background
The soil has temperature due to solar radiation and heat in the earth, and the temperature of the soil at different depths is different. Meanwhile, the temperature of the soil has a periodic variation because the surface temperature is periodically changed along with the day-night or seasonal variation of the solar radiation. In each temperature variation cycle, a maximum value and a minimum value occur. The time at which the temperature is highest or lowest gradually delays as the depth of the soil increases. Meanwhile, the annual amplitude of the soil temperature is rapidly reduced along with the increase of the depth of the soil layer.

By utilizing the characteristics of soil temperature, a new soil energy storage technology is followed, in particular to a ground source heat pump technology in recent years. But the installation depth of the ground source heat pump is fixed and the installation position can not be changed, so that the changed engineering quantity is large, namely the installation is carried out again. However, this inevitably causes the release amount of the soil around the ground source heat pump to be larger than the absorption amount after the ground source heat pump is used for a period of time, or the absorption amount is larger than the release amount, which causes heat imbalance and affects the use efficiency of the ground source heat pump.

The embedding mode can be divided into two modes, the first mode is to dig out the soil below the through hole 101, then put the spiral pipe 2 into the vertical pipe 3, and then backfill the soil; and the other is that the soil is not dug out, the spiral pipe 2 is moved downwards in the rotation process by direct falling, and the spiral pipe 2 is rotated to a specified position like screwing. Because the spiral pipe 2 occupies a limited space, the problem of soil export does not need to be considered, and the soil can be squeezed to the periphery in the process of rotating the spiral pipe 2, so that the soil is tighter.
B. When storing heat energy: a heat source flows in through the liquid inlet main pipe 10, then flows into the spiral pipe 2 through each liquid inlet branch pipe 6, the extension bar 4 and the vertical pipe 3, heats the phase change pipe 203 inside the spiral pipe, the phase change material inside the phase change pipe 203 absorbs heat to generate phase change, stores heat energy, bypasses the first partition plate 202, flows into the other cavity from the tail end of the spiral pipe 2, then flows into the liquid return main pipe 9 along the vertical pipe, the extension bar and the liquid return branch pipe 7, and circulates;
C. when releasing heat energy: the circulation paths of the cold source are the same, and the cold source enters the spiral pipe 2 to absorb the heat inside the phase change pipe 203, so that the temperature of the cold source is increased;
D. when the temperature is adjusted by utilizing the soil temperature: in summer, the underground soil temperature is lower than the outdoor temperature and the indoor temperature, the phase change pipe 203 is in contact with the spiral pipe 2 through the first partition plate 202 to conduct heat, the temperature stored by the phase change pipe 203 is the same as the soil temperature, the circulating liquid flows into the spiral pipe 2 to cool, then the indoor space is refrigerated, and the indoor temperature is adjusted;
in winter, the underground soil temperature is higher than the outdoor temperature and the indoor temperature, the circulating liquid flows into the spiral pipe 2 to be heated, then the indoor is heated, and the indoor temperature is adjusted;
E. because the adjacent spiral pipes 2 are arranged in a staggered manner, the distance between every two adjacent spiral pipes 2 is long, so that the heat energy of the soil around the spiral pipes is conveniently utilized, and the spiral pipes 2 are utilized orderly by adjusting the opening and closing of the electric control valves 8 on the liquid inlet branch pipes 6 and the liquid return branch pipes 7, so that the unbalance of the temperature layer of the underground soil is avoided;
F. the height of each spiral pipe 2 is adjusted regularly, so that the spiral pipes 2 fully utilize the heat energy of soil, when the spiral pipes 2 move upwards, the shifter is fixed, the connecting piece 15 is sleeved on the vertical rod 3, the arc plate 1503 penetrates through the first clamping ring 301, the hydraulic station is connected with the hydraulic cylinder 13, the piston rod 1301 is controlled to move upwards, when the piston rod 1301 moves upwards, the connecting piece 15 rotates, the arc plate 1503 rotates to the position below a radial connecting rod between the first clamping ring 301 and the vertical rod 3, the connecting piece 15 moves upwards to drive the vertical rod 3 to move upwards and synchronously rotate, and the cutting surface 201 is arranged on the outer side of the threaded pipe 2, so that the resistance of soil to the spiral pipe 2 can be reduced by moving upwards in the rotating process, and the threaded pipe 2 can move upwards and downwards conveniently;
when the threaded pipe 2 moves downwards, the upper end cover 5 above the vertical pipe 3 is taken down, the bottom of the extension bar 4 is fixedly connected with the vertical pipe 3, then the threaded pipe 12 moves upwards, the connecting piece 15 is sleeved at the top of the extension bar 4, and the piston rod 1301 pushes the threaded pipe 2 to rotate downwards through the connecting piece 15.
The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
