Problems solved by technology
Regardless of whether the pipe is lowered manually or mechanically, there is a problem at present, that is, only the upper end of the buried pipe is subjected to downward force. Due to the flexibility of the buried pipe, it is difficult to keep the buried pipe straight in the borehole, thus Leading to large down pipe resistance, slow down pipe speed and long construction period

The invention relates to a burying device of a buried heat exchanger and capable of applying force at the borehole bottom. The buried heat exchanger comprises two buried pipes and a U-shaped elbow connecting the bottoms of the two buried pipes; the burying device comprises a counterweight piece which can be put into a borehole, two first guiding wheels oppositely arranged at the top of the counterweight piece, a pulling rope and two first rope winders; and one end of the pulling rope is connected with one of the first rope winders, and the other end of the pulling rope sequentially winds around one first guiding wheel, the U-shaped elbow and the other first guiding wheel and then is connected with the other first rope winder. The burying device can apply force to the upper ends and the lower ends of the buried pipes, and thus has the advantages of being high in pipe-down speed, small in resistance and short in construction period.
Description
Technical field [0001] The invention relates to a buried device for a buried heat exchanger capable of applying force at the bottom of a borehole. Background technique [0002] The buried heat exchanger is a device that utilizes the relatively stable temperature of the underground soil and exchanges heat between the soil and the pipeline system buried in the soil around the building. The piping system in the soil and the piping system in the building are respectively provided with circulating fluid. In winter, the soil acts as a heat source. The circulating fluid absorbs the heat from the soil and provides heating to the building through a heat pump unit; in summer, the soil As a cold source, the circulating fluid absorbs heat in the building and discharges it to the soil through the heat pump unit. Compared with the traditional coal-fired, gas-fired heating and air-conditioning cooling methods, the buried heat exchanger only consumes a small amount of electric energy to achieve...
