Description

Technical Field

[0001] The utility model relates to the technical field of probe pipes, in particular to an assembled ground source heat pump probe pipe. Background Art

[0002] Geothermal heat pump technology, invented by Austrians in the 1980s, offers a valuable opportunity to maximize the use of natural heat and cooling while reducing electricity and other energy consumption. With China's increasing emphasis on energy conservation and emission reduction, geothermal heat pump technology has seen strong growth in China. Initially used in high-end residential buildings such as villas, geothermal heat pumps have recently gained widespread adoption in large public buildings.

[0003] A ground-source heat pump system is a central air conditioning system that provides cooling, heating, and domestic hot water to buildings at low operating costs. It boasts significant environmental and energy-saving advantages. The ground below the surface (6 meters below ground) has a relatively constant temperature, 20°C higher than the average outdoor temperature in winter, making it an excellent low-temperature heat source. In summer, it averages 12°C lower than the outdoor temperature, making it an excellent heat sink with high heat capacity and renewable energy. As early as the 1930s, Europe pioneered the innovative invention and use of ground-source heat pump central air conditioning systems, combining modern heat pump technology with ground temperature. Because the ground temperature is relatively constant, ground-source heat pump central air conditioning systems can achieve approximately 40% energy savings compared to air-source heat pumps. In winter, the system absorbs low-grade heat energy from the subsoil and raises it to high-grade heat energy to heat the building, while also storing cold energy in the subsoil for summer cooling. In summer, the system transfers heat from the building to the subsoil, achieving summer cooling while also storing heat in the ground for winter use.

[0004] Geothermal heat pumps are extremely durable, with very few moving parts. All components are either buried underground or installed indoors, shielding them from harsh outdoor weather. Therefore, they are maintenance-free air conditioning and heating systems, saving maintenance costs. However, because most of the piping is buried underground, leaks can be difficult to detect. Therefore, a prefabricated geothermal heat pump probe is required to inspect the underground piping and ensure proper operation. Utility Model Content

Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0025] As attached Figure 1-4 The assembled ground source heat pump probe shown includes a first shell 1 and a second shell 2 assembled with the first shell 1 to form an insulation sleeve. The cross-sectional profiles of the first shell 1 and the second shell 2 are both arc-shaped, and the first shell 1 and the second shell 2 are connected into a whole by bolts.

[0026] One end of the first shell 1 and the second shell 2 is provided with a accommodating portion 12, and a rotation detection component is detachably arranged in the accommodating portion 12. The rotation detection component includes a gear 31, which is meshed and connected with an inner gear ring 32. Rotating brackets 33 are installed on both sides of the gear 31, and a servo motor 34 for driving the gear 31 to rotate is fixedly installed on any one of the brackets 33.

[0027] The bracket 33 is also fixed with a temperature sensor 332 and an eddy current sensor 333. The temperature sensor 332 can monitor the surface temperature of the heat pump pipeline 5 in real time, while the eddy current sensor 333 can detect cracks in the heat pump pipeline 5 so that the staff can repair the damaged or broken pipeline in time.

[0028] In some embodiments, the housing 12 is provided with a raised locking protrusion 121. The inner gear ring 32 has a circular hole corresponding to the locking protrusion 121. The locking protrusion 121 locks the inner gear ring 32 in its rotation. Rotation grooves 321 are provided on both sides of the inner gear ring 32. The bracket 33 is equipped with a protrusion 331 that fits into the rotation grooves 321, allowing the bracket 33 to rotate around the axis of the inner gear ring 32. Furthermore, a sealing ring is provided on the end surface of the housing 12.

[0029] In some embodiments, the inner gear ring 32 can be split into two parts along the radial direction, and both parts can be installed in the receiving portions 12 of the first shell 1 and the second shell 2 .

[0030] In some embodiments, both ends of the first shell 1 and the second shell 2 are provided with semicircular flanges 4 , and the semicircular flanges 4 are provided with first through holes 41 for connecting bolts.
