Description

Technical Field

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

[0002] Geothermal heat pump systems, also known as ground source heat pumps, use geothermal energy (soil, groundwater, surface water, low-temperature geothermal water, and tailwater) as the cooling source for summer cooling and the low-temperature heat source for winter heating. They provide heating, cooling, and domestic hot water. Laying the pipes is one of the key aspects of the construction of buried pipe ground source heat pump systems, as the depth of the pipes determines the total amount of heat extracted. Therefore, the depth of the pipes must be guaranteed. For buried pipe ground source heat pump systems, especially vertical buried pipe ground source heat pump systems, the drilling depth can reach over 100 meters.

[0003] According to the patent website, a ground source heat pump buried pipe assembly and its usage method are disclosed (authorization announcement number: CN 117967872). B) describes "This invention discloses a ground source heat pump buried pipe installation assembly and its usage method, belonging to the field of ground source heat pump pre-buried construction technology. This ground source heat pump buried pipe installation assembly and its usage method push the pre-buried pipe vertically downwards using a telescopic pipe-laying rod. Furthermore, during the pipe-laying process, a flap-shaped pipe clamp can be installed with the buried pipe, improving construction efficiency and preventing the flap-shaped pipe clamp from falling off due to deviation from the center of the buried hole, thus avoiding problems affecting subsequent construction. Secondly, by rotating the telescopic pipe-laying rod, the first toothed plate drives the second toothed plate and the first gear through the connecting block, causing one end of the insert plate to insert into the side wall of the buried hole, thereby achieving a pre-fixing effect and preventing the buried pipe from floating. During the upward lifting of the telescopic pipe-laying rod, the torsion spring causes the first toothed plate to flip downwards to maintain its vertical position and engage with the second gear. Finally, the rope reel winds up the rope, driving the movable column and fixed cone to insert into the side wall of the buried hole, thus completing the installation and laying of the pre-buried pipe."

[0004] First, the pipe fitting is inserted into the borehole, and the pipe body is wrapped by the arc-shaped clamp. The clamping force is adjusted by bolts to achieve initial fixation. The bottom of the clamp is connected to the borehole casing or wall through a support, and the built-in elastic element buffers the displacement caused by soil settlement and temperature changes. Finally, the clamp position is locked by the locking structure to complete the fixation. There are some problems: First, the installation steps are numerous and the operation is cumbersome. The clamp is a fixed size and it is difficult to adapt to buried pipes of different diameters, which limits its practicality. At the same time, the buried pipe is underground for a long time, and the temperature fluctuates with the season, soil and heat pump operation. If rigid fixation is used, the stress generated by thermal expansion and contraction of the pipe body cannot be released, which can easily lead to deformation and affect the service life. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a ground source heat pump installation device for buried pipes. By adjusting the cooperation of the rotating rod, screw, and cross plate II in the adjustment component, as well as the guiding effect of the moving component, the distance between the first and second moving rings can be precisely adjusted, thereby controlling the opening and closing degree of the rotating arc plate. This allows it to adapt to pipes of different diameters, significantly improving the versatility of the device and the flexibility of the pipe-laying operation. The combination design of the spring and clamp in the protection component, along with the buffer rubber, forms a multi-level buffer protection for the pipe during the pipe-laying process, effectively reducing the rigid collision between the pipe and the device, reducing the risk of scratches or deformation on the surface of the pipe, and ensuring the installation quality of the buried pipe.

[0006] The purpose of this utility model is achieved by the following technical solution: a ground source heat pump installation device for buried pipes, including a lower pipe sleeve, pipe fittings, a cross plate connected to the lower pipe sleeve, an adjustment component connected to the cross plate, a movable ring slidably connected to the cross plate, several L-shaped plates arranged in a circular array on the movable ring, a rotating arc plate rotatably connected to one end of each L-shaped plate, an adjustment plate rotatably connected to the other end of the L-shaped plate, a movable ring rotatably connected to the adjustment plate, a fixing component slidably connected to the pipe fittings, and a protection component connected to the rotating arc plate. The rotating arc plate can rotate and move closer to or away from the pipe fittings. When the rotating arc plate moves closer to the pipe fittings, the protection component can fit against the surface of the pipe fittings for protection. The adjustment component is used to adjust the opening of the arc plate.

[0007] In one optional embodiment, the adjusting assembly includes a rotating rod rotatably connected to the center of the first cross plate, a rotating block fixedly connected to one end of the rotating rod, a screw fixedly connected to the other end of the rotating rod, a second cross plate threadedly connected to the screw, the second cross plate moving along the axial direction of the screw, and a moving assembly disposed on the first and second cross plates. The moving assembly is used to adjust the first and second moving rings to move closer to or away from the rotating rod, and the second cross plate is slidably connected to the lower sleeve.

[0008] In one optional embodiment, the moving component includes a threaded rod rotatably connected to a cross plate, a limiting rod two fixedly connected to the cross plate, and a limiting rod one symmetrically connected to the cross plate, wherein the limiting rod one and the limiting rod two are used to guide the moving ring one and the moving ring two.

[0009] In one optional embodiment, the second movable ring has a plurality of through holes arranged in a circular array, and the adjusting plate is slidably connected to the second movable ring through the through holes.

[0010] In one optional embodiment, when the first moving ring moves away from the second moving ring, the adjusting plate causes the rotating arc plates on the L-shaped plate to move closer to each other; when the first moving ring moves closer to the second moving ring, the adjusting plate causes the rotating arc plates on the L-shaped plate to move away from each other.

[0011] In one optional embodiment, the protective component includes a spring fixedly connected to one end of the rotating arc plate, a clamping plate fixedly connected to the other end of the spring, and sliding rods symmetrically arranged on the cross plate, with the sliding rods fixedly connected to the clamping plate.

[0012] In one optional embodiment, a through hole is provided on the rotating arc plate, and the sliding rod is slidably connected to the rotating arc plate through the through hole.

[0013] In one alternative embodiment, the surface of the clamp is provided with cushioning rubber.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. By adjusting the cooperation between the rotating rod, screw and cross plate II in the adjustment component, as well as the guiding effect of the moving component, the distance between the moving ring I and the moving ring II can be precisely adjusted, thereby controlling the opening and closing degree of the rotating arc plate. This can adapt to pipes of different diameters, significantly improving the versatility of the device and the flexibility of pipe lowering operation.

[0016] 2. The combination design of springs and clamps in the protection components, along with buffer rubber, forms multi-level buffer protection for the pipe fittings during the pipe laying process. This effectively reduces rigid collisions between the pipe fittings and the device, lowers the risk of scratches or deformation on the pipe fitting surface, and ensures the installation quality of the buried pipe.

[0029] The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or apparatus.

[0030] Please refer to Figure 1-8 The ground source heat pump installation device includes a lower pipe sleeve 1, a pipe fitting 4, a cross plate 21 connected to the lower pipe sleeve 1, an adjusting component connected to the cross plate 21, a movable ring 212 slidably connected to the cross plate 21, several L-shaped plates 210 arranged in a circular array on the movable ring 212, a rotating arc plate 211 rotatably connected to one end of each L-shaped plate 210, an adjusting plate 29 rotatably connected to the other end of the L-shaped plate 210, a movable ring 28 rotatably connected to the adjusting plate 29, a fixing component 214 slidably connected to the pipe fitting 4, and a fixing component connected to the rotating arc plate 211. The protective component on the pipe 4 allows the rotating arc plate 211 to rotate and move closer to or away from the pipe 4. When the rotating arc plate 211 moves closer to the pipe 4, the protective component can fit against the surface of the pipe 4 for protection. The adjustment component is used to adjust the opening of the arc plate 211. With the cross plate 21 as the support base, the adjustment component, the moving ring 28, the moving ring 212, the L-shaped plate 210 and other components are integrated to form an adjustable clamping structure, which provides structural support for the subsequent control of the opening and closing of the rotating arc plate 211 by the adjustment component. At the same time, the protective component is directly connected to the rotating arc plate 211 to ensure real-time protection of the pipe 4.

[0031] In a preferred embodiment of this utility model, the adjustment assembly includes a rotating rod 22 rotatably connected to the center of the first cross plate 21, a rotating block 24 fixedly connected to one end of the rotating rod 22, a screw 23 fixedly connected to the other end of the rotating rod 22, and a second cross plate 25 threadedly connected to the screw 23. The second cross plate 25 moves along the axial direction of the screw 23 and a moving assembly is provided on the first cross plate 21 and the second cross plate 25. The moving assembly is used to adjust the first moving ring 28 and the second moving ring 212 to move closer to or further away from the rotating rod 22. The second cross plate 25 is slidably connected to the lower sleeve 1. The rotating block 24 operates the rotating rod 22 to drive the screw 23 to rotate, so that the second cross plate 25 moves along the axial direction of the screw 23. The displacement is transmitted through the moving assembly, and the distance between the first moving ring 28 and the second moving ring 212 is precisely controlled, thereby realizing the adjustment of the opening and closing degree of the rotating arc plate 211, adapting to pipes 4 of different diameters, and improving the versatility of the device.

[0032] In a preferred embodiment of this utility model, the moving component includes a threaded rod 26 rotatably connected to a cross plate 21, a limiting rod 213 fixedly connected to a cross plate 21, and a limiting rod 27 symmetrically connected to a cross plate 25. The limiting rods 27 and 213 guide the moving rings 28 and 212. The threaded rod 26 cooperates with the limiting rods 27 and 213 to provide a stable guiding path for the movement of the moving rings 28 and 212, avoid displacement deviation, ensure the precise pushing of the adjusting plate 29 onto the L-shaped plate 210, and ensure the reliability of the opening and closing adjustment of the rotating arc plate 211.

[0033] In a preferred embodiment of this utility model, the second movable ring 212 is provided with a plurality of through holes arranged in a circular array. The adjusting plate 29 is slidably connected to the second movable ring 212 through the through holes. The through hole design makes the sliding connection between the adjusting plate 29 and the second movable ring 212 smoother, reduces frictional resistance, facilitates the rapid response of the adjusting plate 29 when the first movable ring 28 moves, and improves the sensitivity of the opening and closing adjustment of the rotating arc plate 211.

[0034] In a preferred embodiment of this utility model, when the first moving ring 28 moves away from the second moving ring 212, the adjusting plate 29 causes the rotating arc plates 211 on the L-shaped plate 210 to move closer to each other. When the first moving ring 28 moves closer to the second moving ring 212, the adjusting plate 29 causes the rotating arc plates 211 on the L-shaped plate 210 to move away from each other. The relative displacement of the first moving ring 28 and the second moving ring 212 drives the adjusting plate 29 to push and pull the L-shaped plate 210, thereby controlling the opening and closing direction of the rotating arc plates 211 and meeting the clamping requirements of different pipe diameters.

[0035] Please refer to Figure 7 In a preferred embodiment of this utility model, the protective component includes a spring 32 fixedly connected to one end of the rotating arc plate 211, a clamping plate 33 fixedly connected to the other end of the spring 32, and sliding rods 31 symmetrically arranged on the cross plate 21. The sliding rods 31 are fixedly connected to the clamping plate 33, and the spring 32 and the clamping plate 33 are combined to form a buffer structure. When the rotating arc plate 211 clamps the pipe 4, the spring 32 absorbs the impact force through deformation, and the sliding rods 31 restrict the movement direction of the clamping plate 33 to avoid deviation, effectively reducing frictional damage to the surface of the pipe 4.

[0036] In a preferred embodiment of this utility model, a through hole is provided on the rotating arc plate 211, and the sliding rod 31 is slidably connected to the rotating arc plate 211 through the through hole. The through hole design makes the sliding connection between the sliding rod 31 and the rotating arc plate 211 more stable, avoids the sliding rod 31 from getting stuck when the rotating arc plate 211 rotates, and ensures that the buffering function of the protection component is functioning normally.

[0037] In a preferred embodiment of this utility model, the surface of the clamping plate 33 is provided with buffer rubber. The buffer rubber further enhances the flexibility of the clamping plate 33 when it comes into contact with the pipe 4, reduces the wear caused by rigid collision, and improves the protection effect on the pipe 4.

[0038] Please refer to Figure 8 Other embodiments: The protective component can also adopt other structures in the prior art. Replacing the sliding rod 31 and the spring 32 with rubber or buffer sponge can adapt to the size of the pipe 4 when it expands and contracts with heat. Moreover, the rubber or buffer sponge structure is simple and the cost is relatively low.

[0039] During operation, the lower sleeve 1 is first connected to the fitting 4. The rotating block 24 in the adjusting assembly is rotated, causing the rotating rod 22 to rotate, which in turn causes the screw 23 to rotate. Since the cross plate 25 is threadedly connected to the screw 23 and slidably connected to the lower sleeve 1, the cross plate 25 moves along the axis of the screw 23. At this time, the threaded rod 26, the limiting rod 1 27, and the limiting rod 213 in the moving assembly work together to guide the moving ring 1 28 and the moving ring 212 toward or away from the rotating rod 22. When the moving ring 1 28 moves away from the moving ring 212, the adjusting plate 29, through its sliding connection with the moving ring 212, pushes the rotating arc plate 211 on the L-shaped plate 210 to move closer to each other; when the moving ring 1 28 moves closer to the moving ring 212, the adjusting plate 29 drives the rotating arc plate 211 to move away from each other, thereby adjusting the opening and closing state of the rotating arc plate 211 to adapt to the size of the fitting 4. Meanwhile, the sliding rod 31 in the protective assembly slides in the through hole as the rotating arc plate 211 rotates, and the spring 32 applies a buffering force to the pipe fitting 4 through the clamping plate 33. The buffering rubber on the surface of the clamping plate 33 further reduces the friction damage to the pipe fitting 4 during the pipe laying process. The fixing member 214 slides and fixes the pipe fitting 4 in a fixed position, and finally completes the pipe laying operation of the underground pipe.

[0040] Although only certain components and embodiments of this application have been illustrated and described, many modifications and alterations will be apparent to those skilled in the art without actually departing from the scope and spirit of the claims, such as variations in the size, dimensions, structure, shape and proportion of the various elements, installation arrangement, material use, color, orientation, etc.

[0041] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
