Description

Technical Field

[0001] This utility model relates to the field of buried pipe technology, specifically a spliced ​​buried pipe for ground source heat pumps. Background Technology

[0002] A ground source heat pump is a highly efficient and energy-saving air conditioning device that utilizes shallow geothermal resources (also known as geothermal energy, including groundwater, soil, or surface water) to provide both heating and cooling. Geothermal heat pumps transfer low-grade heat energy to high-grade heat energy by inputting a small amount of high-grade energy (such as electricity).

[0003] Ground source heat pumps typically work with buried pipes to exchange heat with geothermal resources. Existing buried pipe systems often use two integral straight pipes connected to a U-shaped pipe. These integrated straight pipes are transported to the site and then cut according to the actual conditions, which is inflexible and requires large trucks for transport, making it inconvenient. While spliced ​​buried pipes exist, the connectors used in these systems are directly clipped onto the straight pipes, making them prone to slippage and resulting in poor stability between the connectors and the pipes. Therefore, an improved technology is urgently needed to solve this problem in the existing technology. Utility Model Content

[0025] Please see Figure 1-4 This utility model provides a technical solution: a spliced ​​buried pipe for a ground source heat pump, including a straight pipe 1, a bend 2, a connecting cylinder 3, a stabilizer 4, and a connection port 5. There are several straight pipes 1, connecting cylinders 3, and stabilizers 4. Two adjacent straight pipes 1 are connected to each other through the connecting cylinder 3. The two ends of the bend 2 are respectively connected to the corresponding straight pipes 1 through the connecting cylinder 3. The top of the two straight pipes 1 at the top is provided with a connection port 5. One end of the connection port 5 is provided with a third external thread interface 10. The connection port 5 is connected to the internal thread 8 at the end of the corresponding connecting cylinder 3 through the third external thread interface 10. The other end of the connection port 5 is provided with a pipe interface 11. The pipe interface 11 is connected to the pipe of the ground source heat pump group. The connecting cylinders 3 on both sides are corresponding to each other and are respectively connected to the stabilizers 4.

[0026] The straight pipe 1 is provided with a first external thread interface 6 at both ends, the bent pipe 2 is provided with a second external thread interface 7 at both ends, and the connecting cylinder 3 is provided with an internal thread 8 at both ends. The straight pipe 1 is connected to the corresponding internal thread 8 at the end of the connecting cylinder 3 through the first external thread interface 6, and the bent pipe 2 is connected to the corresponding internal thread 8 at the end of the connecting cylinder 3 through the second external thread interface 7.

[0027] An annular groove 9 is provided in the middle of the connecting cylinder 3;

[0028] like Figure 5-6 As shown, the stabilizer 4 includes a connecting plate 401, a U-shaped component 402, a limiting screw 403, and a locking nut 404. The connecting plate 401 has U-shaped components 402 at both ends and several connecting holes 406 for connection with an external support via bolts and nuts. The U-shaped component 402 mates with the corresponding annular groove 9 of the connecting cylinder 3. The height of the U-shaped component 402 is the same as the height of the annular groove 9 to ensure that the connecting cylinder 3 does not wobble up and down after being connected with the U-shaped component 402, thus ensuring connection stability. The inner width of the U-shaped part 402 is consistent with the outer diameter of the annular groove 9 of the connecting cylinder 3 to ensure that the connecting cylinder 3 and the U-shaped part 402 will not wobble in the horizontal direction after they are connected, thus further ensuring the stability of the connection. A limit screw 403 is provided at the outer end of the U-shaped part 402. Through holes 405 are opened on both sides of the outer end of the U-shaped part 402. The limit screw 403 passes through the through holes 405 on both sides of the outer end of the U-shaped part 402 to realize the connection between the limit screw 403 and the U-shaped part 402. The limit screw 403 cooperates with the locking nut 404.

[0029] Installation method and operating principle: Connect the straight pipe 1 to the connecting cylinder 3 through the first external thread interface 6 to obtain two straight pipes 1. Then connect the bottom connecting cylinder 3 to the second external thread interface 7 of the bend pipe 2 to complete the connection between the straight pipe 1 and the bend pipe 2. At the same time, connect the stabilizing frame 4 to the connecting cylinder 3. Specifically, mate the U-shaped part 402 of the stabilizing frame 4 with the corresponding annular groove 9 of the connecting cylinder 3. Then pass the limiting screw 403 through the through holes 405 on both sides of the outer end of the U-shaped part 402. Finally, screw the locking nut 404 onto the limiting screw 403. At this time, through the cooperation of the limiting screw 403 and the U-shaped part 402, the connecting cylinders 3 on both sides are limited, completing the assembly. At this time, the entire buried pipe forms a U-shaped structure, with the middle position supported by the stabilizing frame 4. This utility model has a reasonable structure. The buried pipe is spliced ​​together by straight pipe 1, bent pipe 2 and connecting cylinder 3. It can be flexibly spliced ​​according to the actual situation, which greatly improves the flexibility and applicability. The connecting cylinder 3 is provided with an annular groove 9. The connecting cylinders 3 on both sides correspond one-to-one. The corresponding connecting cylinders 3 are respectively connected to the U-shaped parts 402 and the limiting screws 403 at both ends of the stabilizing frame 4, thereby ensuring the support and stability of the entire buried pipe and avoiding the deformation of the buried pipe due to splicing.
