Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an auxiliary device for the installation of geothermal heat pump well pipelines. Background Technology

[0002] Ground source heat pump technology is a highly efficient and energy-saving air conditioning system that utilizes shallow geothermal resources. When implementing a ground source heat pump project, it is necessary to drill holes underground and bury U-shaped or W-shaped heat exchange pipes (i.e., buried pipes). These buried pipes are connected upwards through wellheads and are an important component of the entire system.

[0003] However, in actual engineering construction, the installation and connection of geothermal heat pump well pipelines present certain technical challenges. After drilling, the construction site often features soft soil or uneven surfaces with accumulated debris, lacking a stable and robust foundation. During critical operations such as pipeline lowering, docking, heat fusion, and water injection pressure testing, a temporary, stable support platform is needed to support and position the pipeline. Existing construction methods mostly employ temporary, simple supports or operate directly on unstable ground. These temporary solutions are not only time-consuming and inefficient, but also pose safety hazards during pipeline docking and high-pressure testing due to unstable support points, making it difficult to guarantee the accuracy and reliability of the pipeline connection.

[0004] Furthermore, ground source heat pump projects are characterized by numerous locations spread across a wide area and the need for frequent site relocation. Existing auxiliary equipment or temporary platforms are often bulky, complex to install and dismantle, or difficult to quickly and easily remove and store from the ground once fixed. This significantly reduces the work efficiency of construction personnel and increases the transportation and deployment costs of auxiliary equipment.

[0005] Therefore, this utility model proposes an auxiliary device for the installation of ground source heat pump well pipelines to solve the problem that the existing technology lacks a pipeline installation auxiliary platform that can be quickly deployed and stably anchored on the construction site, and can be easily retrieved after the operation is completed, which affects the construction efficiency and safety.

[0010] Preferably, the limiting component further includes an outer tube, a movable rod, and a force-applying block. The outer tube is sleeved outside the first fixed rod. The movable rod is slidably disposed inside the outer tube. The force-applying block abuts against the force-receiving block in the locked state. By axially moving the movable rod, the force-applying block can be driven to disengage from the force-receiving block, thereby releasing the limiting lock on the first fixed rod.

[0011] Preferably, the limiting component further includes a fixing ring and a spring, the fixing ring is fixed on the moving rod, one end of the spring abuts against the force-applying block, and the other end abuts against the fixing ring.

[0012] Preferably, the ground source heat pump well pipeline installation auxiliary device further includes a support for supporting the pipeline, a rotating rod connected to the support, and a disassembly mechanism disposed in the housing. The rotating rod and the disassembly mechanism cooperate with each other to realize the detachable connection between the support and the housing.

[0013] Preferably, the disassembly mechanism includes a second fixing rod and a limiting block. The second fixing rod rotates in conjunction with the first rotating rod, and the limiting block is controlled by the rotation of the second fixing rod to move between a locked position that engages with the outer casing and an unlocked position that disengages from the casing.

[0014] Preferably, the disassembly mechanism further includes a force-applying column, and the limiting block abuts against the force-applying column when it moves to the unlocked position.

[0015] Preferably, the disassembly mechanism further includes a second spring and a damping rod, both of which are connected to the limiting block.

Detailed Implementation

[0026] Example: Reference Figures 1 to 6 This utility model provides an auxiliary device for the installation of ground source heat pump well pipes, which aims to solve the problem that existing auxiliary devices for the installation of ground source heat pump pipes have complex structures, cannot be quickly deployed, fixed and stored on the construction site, and affect construction efficiency.

[0027] like Figure 1 As shown, the auxiliary device for installing geothermal heat pump well pipeline includes a housing 1 as an installation base, and multiple fixing plates 6 extending circumferentially from the housing 1. The fixing plates 6 are fixedly connected to the housing 1, and the bottom of the housing 1 is also fixedly connected to a bottom cone column 9 for insertion into the ground. The core structure of the device is a rotating mechanism 5 located at the end of each fixed plate 6. The rotating mechanism 5 is used to drive and lock the bottom cone rod 55 that can be inserted into the ground. Reference Figures 2 to 4 The rotating mechanism 5 specifically includes a rotating rod 51, one end of which is fixed to a fixed plate 6. A rotating wheel 52 is rotatably mounted on the rotating rod 51. A bottom cone rod 55 is fixedly connected to the outer peripheral wall of the rotating wheel 52 via a connecting block 57. The rotating mechanism 5 also includes a fixed rod 54, which passes through the rotating wheel 52 and drives the rotating wheel 52 to rotate, thereby switching the bottom cone rod 55 between a retracted position within the fixed plate 6 and a working position extending out and perpendicular to the fixed plate 6. A fixed block 53 is fixedly connected to one end of the fixed rod 54 and is connected to the rotating wheel 52 for transmitting the rotation of the fixed rod 54 to the rotating wheel 52. To lock the bottom cone rod 55 in its working position, the device also includes a limiting component 56, which rotates synchronously with the fixed rod 54; see reference Figure 2 and Figure 6 The limiting component 56 includes a second fixing block 561, on which a force-bearing block 567 is provided. When the operator rotates the first fixing rod 54 to switch the bottom cone rod 55 to the working position, the force-bearing block 567 on the second fixing block 561 cooperates with the limiting structure on the second fixing plate 6 to limit the rotation of the first fixing rod 54, thereby reliably locking the bottom cone rod 55 in the working position.

[0028] Reference Figure 2 The limiting component 56 also includes an outer tube 562, which is sleeved on the outside of the fixed rod 54, and a movable rod 563 is slidably disposed inside the outer tube 562; the limiting component 56 also includes a force-applying block 566, which abuts against the force-receiving block 567 in the locked state to limit the movement of the force-receiving block 567; The moving rod 563 is connected to the force-applying block 566 in a transmission manner. When it is necessary to unlock, the moving rod 563 can be moved axially to drive the force-applying block 566 to move, so that it is disengaged from the force-bearing block 567. At this time, the limit lock of the fixed rod 54 is released, and the operator can rotate the fixed rod 54 in the opposite direction to drive the bottom cone rod 55 to rotate back to the storage position. To ensure the structure can automatically reset after unlocking, the unlocking structure also includes a retaining ring 564 and a spring 565. The retaining ring 564 is fixed on the moving rod 563, and one end of the spring 565 abuts against the force-applying block 566, while the other end abuts against the retaining ring 564. During the process of unlocking the force-applying block 566 by driving the moving rod 563, the spring 565 is compressed. When the external force is released, the elastic force of the spring 565 acts on the force-applying block 566, restoring it to its initial position where it can abut against the force-receiving block 567. This unlocking structure with a reset function ensures that the device can stably perform the next unlocking operation.

[0029] As a preferred embodiment, to enable rapid disassembly and installation of the upper support 7 and the lower base, the device further includes the support 7, the rotating rod 3, and the disassembly mechanism 8, such as... Figure 1 As shown, the bracket 7 is used to support the pipe. The rotating rod 3 is connected to the bottom of the bracket 7. The disassembly mechanism 8 is set inside the outer shell 1. The rotating rod 3 and the disassembly mechanism 8 cooperate with each other to realize the detachable connection between the bracket 7 and the outer shell 1. An outer ring 2 is fixedly connected to the upper part of the outer shell 1. The rotating rod 3 is rotatably inserted in the outer ring 2. The bracket 7 includes a fixing plate 4, which is used to directly support the pipe.

[0030] As another preferred embodiment, refer to Figure 1 and Figure 3The disassembly mechanism 8 includes a second fixing rod 81, which rotates in conjunction with the first rotating rod 3; the disassembly mechanism 8 also includes a limiting block 83, which is controlled by the rotation of the second fixing rod 81 and can move between the locked position of the snap-fit ​​housing 1 and the unlocked position of the snap-fit ​​housing 1.

[0031] As another preferred embodiment, refer to Figure 3 The disassembly mechanism 8 also includes a force-applying column 84, which abuts against the force-applying column 84 when the limit block 83 moves to the unlock position to ensure that it is fully unlocked.

[0032] In another preferred embodiment, the disassembly mechanism 8 further includes a second spring 82 and a damping rod 85. The second spring 82 and the damping rod 85 are both connected to the limiting block 83 to provide a restoring force and damping buffer when the limiting block 83 moves, so as to ensure the smoothness of the disassembly operation and prevent misoperation or damage caused by accidental vibration or impact.

[0033] The working principle is as follows: First, the device is deployed and secured: After placing the device at the predetermined position above the wellhead, the operator holds and rotates the first fixing rod 54. The first fixing rod 54 drives the rotating wheel 52 to rotate outside the second rotating rod 51 through the first fixing block 53, thereby driving the connecting block 57 and the bottom cone rod 55 to rotate synchronously, causing the bottom cone rod 55 to rotate from a horizontal position stored inside the second fixing plate 6 to a working position perpendicular to the ground. During the rotation, the limiting component 56 rotates synchronously with the first fixing rod 54. The force-bearing block 567 on the second fixing block 561 in the limiting component 56 is limited by the slot of the limiting structure on the second fixing plate 6. The force-bearing blocks 567 move closer to each other and are locked by the force-applying block 566, thereby locking the first fixing rod 54 and preventing it from rotating in the opposite direction, thus achieving the self-locking fixation of the bottom cone rod 55. Subsequently, the operator applies downward pressure, causing the four bottom cone rods 55 and the central bottom cone column 9 to insert into the ground, completing the stable fixation of the device.

[0034] Next, the pipeline installation work is carried out: After the device is stabilized and fixed, the operator places the pipeline on the fixed plate 4 on the support 7, performs water injection and pressure testing, and after passing the test, the vertical pipeline installation work is carried out by utilizing the rotatability of the fixed plate 4.

[0035] Next, the upper support 7 is disassembled: After the operation is completed, the operator holds the outer ring 2 with one hand and rotates the rotating rod 3 with the other hand. The rotating rod 3 drives the fixed rod 81 in the disassembly mechanism 8 to rotate, so that the limiting block 83 controlled by the fixed rod 81 disengages from the locking of the outer shell 1. Under the coordinated action of the spring 82 and the damping rod 85, the limiting block 83 moves smoothly to the unlocked position and abuts against the force column 84. At this time, the fixed rod 81 can be pulled out of the outer ring 2, thereby realizing the rapid separation of the upper support 7 from the lower outer shell 1.

[0036] Finally, the device is retrieved: When it is necessary to detach the auxiliary device from the ground, the operator needs to first release the lock of the bottom cone rod 55. At this time, pull the moving rod 563 in the outer tube 562 upward. The moving rod 563 drives the fixed ring 564 to move upward and squeeze the spring 565, thereby driving the force block 566 to move upward and release it from the abutment lock on the force block 567. After the lock is released, the operator rotates the fixed rod 54 in the opposite direction. The force block 567 rotates under the limiting action of the fixed plate 6, driving the bottom cone rod 55 to rotate upward. Finally, it rotates and is stored inside the fixed plate 6, which facilitates the transportation and storage of the device.
