Description

Technical Field

[0001] This utility model belongs to the field of buried pipe technology, and in particular relates to an installation structure for shallow geothermal energy buried pipes. Background Technology

[0002] Shallow and medium-depth geothermal energy is a renewable and clean energy source that has been widely used in building heating and cooling in recent years. As the core component of heat exchange, the quality of underground installation and the accuracy of its location directly affect the heat transfer efficiency and operational stability of the geothermal system.

[0003] In existing technologies, the installation of buried pipes mostly involves manual placement and temporary fixing, which generally suffers from problems such as unstable support structures, non-adjustable installation height, and difficulty in accurately controlling the position of the pipes. Especially in environments with uneven terrain or soft backfill, the pipes are prone to displacement or inconsistent burial depth, which in turn affects the overall operating efficiency of the geothermal system. At the same time, buried pipes often require a certain degree of lateral adjustment after installation to adapt to the pre-buried path or joint alignment, but most existing clamping structures are rigidly fixed and lack structural designs that allow for fine-tuning.

[0004] Based on this, this utility model designs a buried pipe installation structure for shallow to medium-depth geothermal energy to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the problems in existing buried pipe installation methods, which mostly rely on manual placement and temporary fixing. These methods often result in unstable support structures, unadjustable installation heights, and difficulty in precisely controlling pipe positions. In particular, in environments with uneven terrain or soft backfill, pipes are prone to displacement or inconsistent burial depths, thus affecting the overall operating efficiency of the geothermal system. Furthermore, buried pipes often require lateral adjustments after installation to adapt to the pre-buried path or joint alignment. However, most existing clamping structures are rigidly fixed and lack structural designs that allow for fine adjustments. Therefore, this utility model proposes a buried pipe installation structure for medium-shallow geothermal energy.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A shallow to medium geothermal energy buried pipe installation structure includes a support base, a base plate fixedly connected to the support base, an adjustment device installed inside the support base, limit devices symmetrically installed on the adjustment device, and a fixing device installed inside the support base.

[0008] The adjusting device includes a first threaded rod and an adjusting hole. A nut is sleeved on the first threaded rod, and a support plate is fixedly connected to the first threaded rod. The nut is fixedly connected to the upper surface of the support base. The adjusting hole is opened inside the support base, and the first threaded rod is located inside the adjusting hole.

[0009] As a further description of the above technical solution:

[0010] The limiting device includes a connecting plate, which is fixedly connected to a support plate. A second threaded rod is provided inside the connecting plate. A pressure plate is fixedly connected to one end of the second threaded rod. A rotating shaft is installed inside the pressure plate, and a rotating rod is sleeved on the rotating shaft.

[0011] As a further description of the above technical solution:

[0012] The pressure plate and the rotating shaft are connected by a rotation.

[0013] As a further description of the above technical solution:

[0014] Limiting rods are symmetrically installed on the outside of the support plate, and a sliding connection is formed between the limiting rods and the connecting plate.

[0015] As a further description of the above technical solution:

[0016] The limiting device also includes several rotating rollers. The support plate has an installation groove, and the several rotating rollers are evenly installed in the installation groove and are rotatably connected to the installation groove.

[0017] As a further description of the above technical solution:

[0018] The fixing device includes a rotating plate and a limiting groove. The rotating plate is covered with an installation sleeve. The limiting groove is formed inside the first threaded rod. The width of the limiting groove is greater than the diameter of the rotating plate's cross-section, and the rotating plate is locked inside the limiting groove.

[0019] As a further description of the above technical solution:

[0020] The mounting sleeve has an internal thread, and the rotating plate has an external thread, forming a threaded connection between the rotating plate and the mounting sleeve.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0022] 1. In this utility model, an adjustment device is set inside the support base. The adjustment device includes a first threaded rod, a nut, and an adjustment hole. During installation, the operator can rotate the first threaded rod to move it up and down in the adjustment hole, thereby driving the support base to rise and fall as a whole, achieving precise control of the installation height of the buried pipe. The nut is fixedly connected to the upper surface of the support base to ensure structural stability and reliability during adjustment. In actual construction, this adjustment mechanism can be flexibly adjusted according to the ground slope or the unevenness of the foundation to ensure that all buried pipes are at the same elevation, avoiding uneven heat transfer or damage to the buried pipes due to different burial depths. It effectively adapts to complex and changing terrain environments and improves the stability of system operation.

[0023] 2. In this utility model, the limiting device and the fixing device work together to achieve stable clamping of the buried pipe and lateral adjustment after installation. The limiting device includes a connecting plate, a second threaded rod, a pressure plate, a rotating shaft, and a rotating rod. The pressure plate is rotatably connected to the connecting plate through the rotating shaft and clamped by the rotating rod. After clamping, the position of the buried pipe can be firmly limited. Furthermore, several rollers are set inside the pressure plate structure and installed in the installation groove of the support plate to form a rolling contact interface, so that the buried pipe can still be finely adjusted and slid in the horizontal direction after being clamped. The operator can push the pipe to move laterally in the initial clamping state to complete the alignment with adjacent pipe sections or interfaces. Finally, the pressure plate is completely locked, realizing a precise and flexible installation process. This structural design not only ensures the clamping stability during pipe installation, but also allows lateral movement within a limited range, greatly improving the convenience of construction and installation accuracy, and helping to improve the overall installation quality and service life of the buried pipe system.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-4 ,

[0032] First embodiment:

[0033] This utility model provides a technical solution: a shallow geothermal energy buried pipe installation structure, including a support base 1, a base plate 2 fixedly connected to the support base 1, an adjustment device 3 installed inside the support base 1, limit devices 4 symmetrically installed on the adjustment device 3, and a fixing device 5 installed inside the support base 1.

[0034] The adjusting device 3 includes a first threaded rod 301 and an adjusting hole 304. A nut 302 is sleeved on the first threaded rod 301, and a support plate 303 is fixedly connected to the first threaded rod 301. The nut 302 is fixedly connected to the upper surface of the support base 1. The adjusting hole 304 is opened inside the support base 1, and the first threaded rod 301 is located inside the adjusting hole 304. The first threaded rod 301 passes through the adjusting hole 304, and the nut 302 sleeved on its outer side is fixedly connected to the upper surface of the support base 1. A threaded transmission structure is formed between the nut 302 and the first threaded rod 301. The operator only needs to rotate the first threaded rod 301 to drive it to move up and down in the adjusting hole 304, thereby precisely adjusting the height of the entire support base 1. This method of adjustment not only provides a continuous adjustment range and precise control, but also relies on the nut 302 to provide sufficient axial support force to ensure that the adjusted position does not revert or shake, adapting to the requirements of complex construction ground elevation.

[0035] Specifically, such as Figure 1-2 As shown, the limiting device 4 includes a connecting plate 401, which is fixedly connected to the support plate 303. A second threaded rod 402 is provided inside the connecting plate 401. A pressure plate 403 is fixedly connected to one end of the second threaded rod 402. A rotating shaft 404 is installed inside the pressure plate 403. A rotating rod 405 is sleeved on the rotating shaft 404. A rotatable connection is formed between the pressure plate 403 and the rotating shaft 404. Limiting rods are symmetrically installed outside the support plate 303, and a sliding connection is formed between the limiting rods and the connecting plate 401.

[0036] During operation, an adjustment device 3 is installed inside the support base 1. The adjustment device 3 includes a first threaded rod 301, a nut 302, and an adjustment hole 304. During installation, the operator can rotate the first threaded rod 301 to move it up and down within the adjustment hole 304, thereby driving the support base 1 to rise and fall as a whole, achieving precise control over the installation height of the buried pipe. The nut 302 is fixedly connected to the upper surface of the support base 1 to ensure structural stability and reliability during adjustment. In actual construction, this adjustment mechanism can be flexibly adjusted according to the ground slope or the unevenness of the foundation to ensure that all buried pipes are at the same elevation, avoiding uneven heat transfer or damage to the buried pipes due to different burial depths. It effectively adapts to complex and changing terrain environments and improves the stability of system operation.

[0037] Second embodiment:

[0038] Specifically, such as Figure 3-4 As shown, the limiting device 4 also includes several rotating rollers 406. The support plate 303 has an installation groove, and the several rotating rollers 406 are evenly installed in the installation groove. The rotating rollers 406 are evenly distributed in the installation groove to form a rotational fit with the installation groove. During installation, the pipe can roll and slide on the rotating rollers 406. This structure allows the buried pipe to be adjusted laterally before the pressure plate 403 is fully clamped, and locks it after the position is aligned by the pressure plate 403. This fit method takes into account both clamping reliability and pre-alignment flexibility, and is particularly suitable for occasions where the connection accuracy of the buried pipe interface is high.

[0039] Furthermore, a rotatable connection is formed between the rotating plate 501 and the mounting groove. The fixing device 5 includes a rotating plate 501 and a limiting groove 503. The rotating plate 501 is covered with a mounting sleeve 502. The limiting groove 503 is opened inside the first threaded rod 301. The width of the limiting groove 503 is greater than the diameter of the cross-section of the rotating plate 501, and the rotating plate 501 is locked in the limiting groove 503. The mounting sleeve 502 has an internal thread, and the rotating plate 501 has an external thread. A threaded connection is formed between the rotating plate 501 and the mounting sleeve 502. The rotating plate 501 is inserted into the limiting groove 503 opened in the first threaded rod 301, and the width of the limiting groove 503 is greater than the diameter of the cross-section of the rotating plate 501, so that the rotating plate 501 can rotate in the groove while being radially limited. This fit structure ensures that the rotating plate 501 will not slip when subjected to axial force, and allows for fine-tuning of its angle. Controllable rotation is achieved without dislocation, which helps to adjust the clamping direction or lock the state.

[0040] During operation, the limiting device 4 and the fixing device 5 work together to achieve stable clamping of the buried pipe and lateral adjustment after installation. The limiting device 4 includes components such as a connecting plate 401, a second threaded rod 402, a pressure plate 403, a rotating shaft 404, and a rotating rod 405. The pressure plate 403 is rotatably connected to the connecting plate 401 through the rotating shaft 404 and is clamped by the rotating rod 405. After clamping, the position of the buried pipe can be firmly limited. Furthermore, several rotating rollers 406 are provided inside the pressure plate 403 structure and installed in the mounting groove of the support plate 303. Inside, a rolling contact interface is formed, allowing the buried pipe to be finely adjusted and slid horizontally even after being clamped. Operators can push the pipe laterally in the initial clamped state to align it with adjacent pipe sections or interfaces, and finally lock the pressure plate 403 completely, achieving a precise and flexible installation process. This structural design not only ensures the clamping stability during pipe installation but also allows for lateral movement within a limited range, greatly improving construction convenience and installation accuracy, and helping to improve the overall installation quality and service life of the buried pipe system.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
