[0002] In a ground source heat pump system, the underground heat exchange pipe is a core component for heat exchange, and is usually buried in the deep soil or combined with a pile foundation, and its long-term stable operation depends on the fixing reliability of the pipe and the adaptability to complex geological environment.
[0003] Among them, soil subsidence (especially uneven settlement caused by soft soil layer, backfill area or underground water dynamic change) is a key risk factor leading to damage of the heat exchange pipe.
[0004] In the prior art, the fixing of the underground heat exchange pipe usually adopts a traditional rigid hoop, which fastens the pipe to a support structure (such as a steel reinforcement cage or a prefabricated support) through bolts, and can only realize static fixing. However, the rigid structure of such a hoop cannot adapt to the axial or radial displacement caused by soil subsidence, and is prone to stress concentration between the hoop and the pipe, which may cause the hoop to break due to overload.

CONCRETE IMPLEMENTING METHOD
[0022] In order to make the purpose and advantages of the utility model more clear and explicit, the utility model is specifically described below in combination with examples. It should be understood that the following text is only used to describe one or several specific implementing modes of the utility model, and does not strictly limit the protection scope of the utility model.
[0023] As shown in Figures 1-4 A soil subsidence prevention underground heat exchange pipe support clamp, comprising two clamp outer hoop bodies 1 and an elastic sealing ring 3, the two clamp outer hoop bodies 1 form a ring-shaped clamp, the elastic sealing ring 3 is installed inside the ring-shaped clamp, and the ring-shaped clamp can slide along the axis direction of the elastic sealing ring 3.
[0024] In use, the elastic sealing ring 3 is sleeved outside the connection between the two underground heat exchange pipe bodies 13, and then the two clamp outer hoop bodies 1 are placed outside the elastic sealing ring 3 for fixation. After fixation, the clamp outer hoop bodies 1 extrude the elastic sealing ring 3, so that the elastic sealing ring 3 is tightly fixed outside the connection between the two underground heat exchange pipe bodies 13, ensuring the sealing of the connection. When the soil outside the underground heat exchange pipe body 13 subsides, the clamp outer hoop bodies 1 are pushed, so that the clamp outer hoop bodies 1 displace outside the elastic sealing ring 3. Through the displacement of the clamp outer hoop bodies 1, the soil subsidence is adapted, so as to buffer the pressure applied to the clamp outer hoop bodies 1 when the soil subsides, and reduce the phenomenon that the clamp outer hoop bodies 1 are damaged due to excessive stress when the soil subsides.
[0025] Meanwhile, a groove is formed in the inside of the elastic sealing ring 3, and a protrusion is arranged outside the end of the clamp outer hoop body 1. Through the cooperation of the groove and the protrusion, the displacement of the elastic sealing ring 3 outside the clamp outer hoop body 1 can be reduced.
[0026] In some embodiments, a connecting support can be fixedly connected between the two clamp outer hoop bodies 1, so as to ensure the stability of the connection between the two clamp outer hoop bodies 1.
[0027] In some embodiments, clamp side ears 9 are fixedly connected outside the ends of the two clamp outer hoop bodies 1. The clamp side ears 9 on the two clamp outer hoop bodies 1 are fixedly connected through bolts 10, so that the combination of the two clamp outer hoop bodies 1 is simple and stable.
[0028] As shown in Figures 1-2 and Figure 4 A sliding cavity 7 is formed in the inner wall of the clamp outer hoop body 1, and the elastic sealing ring 3 is installed inside the sliding cavity 7. Through the arrangement of the sliding cavity 7, the relative position of the clamp outer hoop body 1 and the elastic sealing ring 3 can be limited.
[0029] In some embodiments, a clamp inner hoop body 2 is installed inside the sliding cavity 7, and the clamp inner hoop body 2 can slide along the axis direction of the clamp outer hoop body 1. A limiting groove 4 is formed in the inside of the clamp inner hoop body 2, and the elastic sealing ring 3 is fixedly connected inside the limiting groove 4. Through the limiting groove 4 instead of the contact between the clamp outer hoop body 1 and the elastic sealing ring 3, the limiting groove 4 can apply a fixed extrusion force to the circumferential side of the elastic sealing ring 3, so as to more stably limit the elastic sealing ring 3 and reduce the deformation of the elastic sealing ring 3.
[0030] Meanwhile, the sliding cavity 7 is also fixedly connected with an initial positioning structure that is compatible with the inner clamp body 2 of the clamp, which is used to initially position the inner clamp body 2 of the clamp.
[0031] In some embodiments, the initial positioning structure can be a spring fixedly connected inside the sliding cavity 7, and the spring and the inner clamp 2 of the clamp can be fixedly connected, so that the inner clamp 2 of the clamp can be initially positioned by the spring.
[0032] In other embodiments, the initial positioning structure includes multiple limiting protrusions 8, which are divided into two groups. The two groups of limiting protrusions 8 are located on the upper and lower sides of the inner clamp body 2, respectively, and are used to limit the upper and lower sides of the inner clamp body 2. The limiting protrusions 8 are fixedly connected to the inner wall of the sliding cavity 7, and the fixing method can be welding or bonding. When the force on the limiting protrusion 8 does not exceed the warning value, the inner clamp body 2 can be limited by the limiting protrusion 8. When the force on the limiting protrusion 8 exceeds the warning value, the limiting protrusion 8 is forced to fall off the inner wall of the sliding cavity 7.
[0033] Furthermore, the limiting protrusion 8 is preferably a ceramic block fixedly connected to the inner wall of the sliding cavity 7.
[0034] like Figures 2-4 As shown, in some embodiments, sealing inner rings 6 are fixedly connected to the inner wall of the outer clamp 1 at the positions above and below the sliding cavity 7. The sealing inner ring 6 has a hollow structure and good deformation performance. After the outer clamp 1 is fixed, the sealing inner ring 6 can fill the gap between the outer clamp 1 and the underground heat exchange pipe body 13, reducing the impact of debris falling into the sliding cavity 7 on the outer clamp 1 and the inner clamp 2. Moreover, the sealing inner ring 6 has good deformation performance and has less impact on the movement of the outer clamp 1.
[0035] In other embodiments, a telescopic partition 5 is fixedly connected to the inner wall of the sliding cavity 7. The telescopic partition 5 is fixedly connected to the inner clamp 2 on the side near the inner clamp 2. The telescopic partition 5 can be a latex sheet or a bellows. The setting of the telescopic partition 5 can also reduce the impact of debris falling into the sliding cavity 7 on the outer clamp 1 and the inner clamp 2.
[0036] In some embodiments, the telescopic partition 5 and the sealing inner ring 6 can both be installed on the outer clamp body 1.
[0037] like Figures 1-2 As shown, the outer sides of the two clamp outer bodies 1 are fixedly connected with rubber outer layers 11, which can buffer the uneven settlement force generated during soil settlement.
[0038] The outer rubber layer 11 has through holes 12 that are compatible with the bolt 10, so as to facilitate the operation of the bolt 10.
[0039] The above merely describes preferred embodiments of the present application, and it should be noted that, for those skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should also be considered as the protection scope of the present application. The structures, devices and operation methods not specifically described and explained in the present application are implemented according to conventional means in the art, unless otherwise specified and limited.
