Description

Technical Field

[0001] This utility model relates to the field of ground source heat pump technology, specifically to a ground source heat pump device for buildings. Background Technology

[0002] Ground source heat pump systems, with their advantages of high efficiency, energy saving, environmental friendliness, and stability, have become one of the mainstream devices for heating, cooling, and domestic hot water supply in modern homes. Their core working principle involves heat exchange between an underground heat exchanger and the soil, groundwater, or surface water. A circulating medium (usually antifreeze, water, or a mixture of both) serves as the heat carrier, transferring and converting low-grade underground heat energy into the indoor environment. The cleanliness of the circulating medium directly determines the heat exchange efficiency of the heat exchanger, the flow performance of the piping system, and the overall service life of the system. Therefore, filtration of the circulating medium is a crucial aspect of the operation and maintenance of ground source heat pump systems.

[0003] While existing ground source heat pump systems for residential buildings are generally equipped with basic filters to remove metal debris and impurities that fall off the pipes in the circulating medium, these filters are usually fixed inside the heat pump. They are prone to clogging during the filtration process and are inconvenient to clean. Since the circulation system of a ground source heat pump for residential buildings is a closed or semi-closed structure, impurities will gradually accumulate on the filter after being intercepted. Existing systems often require the system to be shut down and the filter removed for cleaning or replacement. This is not only cumbersome and time-consuming, but also interrupts heating or cooling services. Especially for scenarios with high continuous operation requirements such as heating in winter and cooling in summer, shutdown for cleaning will seriously affect the user experience. Utility Model Content

[0024] Reference Figures 3-6The angle adjustment assembly includes a first gear 15, a first gear ring 16, and a reciprocating rotation assembly. The first gear 15 is coaxially and fixedly mounted on a recoil tube 13, which passes through the first gear 15. The first gear ring 16 is rotatably mounted inside the support housing 6, and the first gear 15 meshes with the first gear ring 16.

The reciprocating moving assembly includes a moving groove 19, an adjusting disc 20, and a first motor 22. The moving groove 19 is formed on the top side wall of the moving block 17, and the inner top wall of the support housing 6 is located on the moving block 17. An adjusting disc 20 is rotatably mounted on the top side of the groove 19. A rotating shaft 21 is rotatably mounted on the eccentric position of the adjusting disc 20.

Specifically, the operation of the first motor 22 can drive the adjusting disc 20 to rotate. The rotation of the adjusting disc 20 can drive the rotating shaft 21 to move around the adjusting disc 20. At the same time, the rotating shaft 21 pushes the side wall of the moving groove 19, causing the moving block 17 and the first rack to move back and forth. Then, through the meshing of the first rack and the first gear 15, the first gear 15 and the adjacent backwash tube 13 are driven to rotate back and forth.

[0025] In this embodiment, during use, after the operator connects the heat pump body 1 to the underground heat exchanger through the second inlet pipe 8 and the first outlet pipe 4, the operator closes the second shut-off valve 10 and the third shut-off valve and opens the first shut-off valve. The operator then controls the heat pump body 1 to operate, allowing impurities mixed in the circulating medium to be filtered through the filter cartridge 7, thus preventing impurities from entering the heat pump body 1 and affecting its service life. After running for a period of time, the operator closes the first shut-off valve and opens the second and third control valves. Then, clean circulating medium is introduced into the first cavity 11 and the backflushing pipe 13 through the backflushing hose 12. The circulating medium is then sprayed onto the surface of the filter cartridge 7 through a nozzle to achieve backflushing of the filter cartridge 7. Simultaneously, the circulating medium is cleaned through the impurity discharge pipe 9. The discharge of impurities facilitates the cleaning and removal of impurities adhering to the filter cartridge 7 from the filter box. During the impurity discharge process, the operator controls the first motor 22 to operate. The operation of the first motor 22 can drive the adjustment plate 20 to rotate. The rotation of the adjustment plate 20 can drive the rotating shaft 21 to move around the adjustment plate 20. At the same time, the rotating shaft 21 pushes the side wall of the moving groove 19, causing the moving block 17 and the first rack to move back and forth. Then, through the meshing of the first rack and the first gear 15, the first gear 15 and the adjacent backwash tube 13 are driven to rotate back and forth. At the same time, through the meshing of the first gear 15 and the first gear ring 16, multiple backwash tubes 13 are driven to rotate back and forth, which facilitates backwashing at different positions of the filter cartridge 7 and improves the backwashing effect.
