Description

Technical Field

[0001] This utility model relates to the field of heat pump unit technology, specifically to a high-efficiency medium-deep geothermal energy heat pump unit. Background Technology

[0002] Medium-deep geothermal heat pump units are a type of equipment that efficiently utilizes medium-deep geothermal energy. By consuming a small amount of electricity, they transfer heat from a low-temperature heat source, such as medium-deep underground rock and soil, to a high-temperature heat source. They are widely used in heating, cooling, and domestic hot water supply.

[0003] A search revealed that patent document CN219713705U discloses a high-efficiency medium-deep geothermal heat pump unit. This heat pump unit uses an adapter between the plate and the docking seat for quick installation and disassembly during the installation process. This ensures the heat transfer effect of the heat pump unit while facilitating its disassembly, greatly improving the convenience of use.

[0004] However, when making a quick connection between the unit and the geothermal pipe, the entire unit needs to be moved. Since the unit is generally quite large, a lot of manual intervention is required during the movement, which reduces the ease of connection between the unit and the geothermal pipe and makes it inconvenient to operate.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model discloses a high-efficiency medium-deep geothermal heat pump unit.

[0025] This utility model provides, for example Figure 1-3 The high-efficiency medium-deep geothermal heat pump unit shown includes a heat pump unit 1 and a geothermal pipe 2. The upper end of the geothermal pipe 2 is connected to a support pipe 3. The outer wall of the support pipe 3 is fitted with a sealing pipe 4. The inner wall of the sealing pipe 4 is provided with connecting threads. The lower end of the outer wall of the heat pump unit 1 is connected to a connecting pipe 5. The outer walls of the support pipe 3 and the connecting pipe 5, which are close to each other, are provided with sealing threads 6, which are threaded into the sealing pipe 4. Through the cooperation between the threads, the connection sealing between multiple pipes can be guaranteed, and the connection between the geothermal pipe 2 and the heat pump unit 1 can be guaranteed to be stable.

[0026] A connecting frame 7 is fixedly installed at the bottom of the upper end of the geothermal pipe 2. The connecting frame 7 is L-shaped. A limiting pipe 8 is fixedly installed at the end of the connecting frame 7. A pushing and rotating mechanism is provided between the limiting pipe 8 and the sealing pipe 4. The pushing and rotating mechanism includes two symmetrically arranged guide blocks 9. The two guide blocks 9 are fixedly installed on the inner wall of the limiting pipe 8. A guide groove 10 is opened on the outer wall of the end of the sealing pipe 4 near the geothermal pipe 2. The guide groove 10 is spirally arranged. The guide block 9 is slidably installed in the guide groove 10. Through the sliding cooperation between the guide block 9 and the guide groove 10, when the position of the guide block 10 is fixed, the sealing pipe 4 can rotate according to the rotation path of the guide groove 10, thereby sealing and fitting the outer wall of the support pipe 3 and the connecting pipe 5 and completing the docking.

[0027] In order to allow the sealing tube 4 to move laterally while rotating itself, and to provide a threaded seal on the outside of the support tube 3 and the connecting tube 5, such as... Figure 2-3 As shown, a connecting ring 11 is fitted on the outer wall of the geothermal pipe 2. A locking bolt 14 is threaded through the outer wall of the connecting ring 11. The locking bolt 14 is screwed into the pipe wall of the geothermal pipe 2. An electric push rod 12 is fixedly installed on the outer wall of the connecting ring 11. A push plate 13 is fixedly installed at the end of the output shaft of the electric push rod 12. A through hole is opened in the inside of the push plate 13, and it is rotated and fitted on the outside of the sealing pipe 4 through a bearing. The electric push rod 12 can stably push the sealing pipe 4 and can rotate inside the push plate 13 during the movement to ensure the thread sealing effect.

[0028] Working principle: When installing this high-efficiency medium-deep geothermal heat pump unit, first install the geothermal pipe 2 to a suitable underground location, and place the heat pump unit 1 in a preset position close to the geothermal pipe 2, so that the connecting pipe 5 and the support pipe 3 are aligned, ensuring that the sealing threads 6 of both can cooperate with the sealing pipe 4. Start the electric push rod 12, and the output shaft of the electric push rod 12 extends to push the push plate 13. Since the push plate 13 is rotated and sleeved on the outside of the sealing pipe 4 through the bearing, the push plate 13 will not restrict the rotation of the sealing pipe 4 while pushing the sealing pipe 4 to move laterally.

[0029] Under the push of the electric push rod 12, the sealing tube 4 approaches the support tube 3 and the connecting tube 5. When the sealing tube 4 approaches to a certain extent, the guide block 9 on the inner wall of the limiting tube 8 contacts and begins to cooperate with the spiral guide groove 10 on the outer wall of the sealing tube 4. As the sealing tube 4 continues to move forward, the guide block 9 slides in the spiral guide groove 10. Because the guide block 9 is fixed on the limiting tube 8 and its position remains unchanged, according to the characteristics of the spiral structure, the sealing tube 4 will rotate while moving forward.

[0030] The rotation of the sealing tube 4 causes the connecting threads on its inner wall to gradually engage with the sealing threads 6 on the outer walls of the support tube 3 and the connecting tube 5. During this process, the electric push rod 12 continuously provides a stable thrust to ensure that the sealing tube 4 can be tightly threaded and sealed on the outside of the support tube 3 and the connecting tube 5, thus completing the rapid connection between the geothermal pipe 2 and the heat pump unit 1.

[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
