Description

Technical Field

[0001] This utility model relates to a positioning device, specifically, to a positioning device for a ground source heat pump pipeline interface. Background Technology

[0002] A ground source heat pump is a highly efficient, energy-saving, and environmentally friendly air conditioning system that utilizes shallow geothermal resources for both heating and cooling. By inputting a small amount of high-grade energy, it transfers energy from a low-temperature heat source to a high-temperature heat source. In winter, it extracts heat from the soil, raises its temperature, and supplies it to the room for heating. In summer, it extracts heat from the room and releases it back into the soil, maintaining a relatively even underground temperature year-round. During installation and use, the ground source heat pump is connected by multiple connecting pipes 3. To ensure the stability of these connections, positioning devices are typically used to position them, reducing the swaying during operation. However, most existing connecting pipes 3 rely on bolts 31 and nuts 32. During the operation of a ground source heat pump, the liquid flowing inside the connecting pipeline 3 impacts the pipeline 3, causing it to shake at the connection point and misalign. This shaking forces the bolt 31 and nut 32 to rotate away from each other, resulting in loosening of the bolts and nuts. Consequently, the fixing effect of the bolts and nuts on the connecting pipeline 3 decreases, making it difficult to maintain a seal at the connection point using only a positioning device. Therefore, we propose a ground source heat pump pipeline interface positioning device. Utility Model Content

[0003] The purpose of this utility model is to provide a ground source heat pump pipeline interface positioning device to solve the problems mentioned in the background art.

[0004] To address the aforementioned problems, the present invention aims to provide a ground source heat pump pipeline interface positioning device, comprising a base, with a positioning mechanism on the upper side of the base. The positioning mechanism includes a moving component and two limiting components. The moving component connects the two limiting components to the base. The moving component drives the two limiting components to move closer to or further away from each other. When the limiting components move to a position close to the bolt and nut, the two limiting components press against the connection point of the connecting pipeline, while simultaneously restricting the position of the bolt and nut.

[0005] As a further improvement to this technical solution, the limiting component includes a mounting ring, which is composed of two semicircular rings connected together, and the mounting ring is slidably sleeved on the outside of the connecting pipeline.

[0006] As a further improvement to this technical solution, the mounting ring has several movable grooves on the side near the bolt, and a positioning block is rotatably connected inside the movable groove. The positioning block has a positioning groove on the side near the bolt, and the positioning groove matches the cross-sectional shape of the bolt and nut.

[0007] As a further improvement to this technical solution, a torsion spring is provided between the positioning block and the inner wall of the movable groove. The two ends of the torsion spring are fixedly connected to the side wall of the positioning block and the inner wall of the movable groove, respectively. When the limiting component restricts the position of the bolt and nut, the torsion spring drives the positioning block to rotate in the direction of tightening the bolt and nut.

[0008] As a further improvement to this technical solution, a sliding groove is provided on the upper side of the base, and the moving component includes a screw rotatably connected inside the sliding groove. Two mounting seats are threadedly connected to the screw, and the upper side of the mounting seats passes through the sliding groove and extends outward.

[0009] As a further improvement to this technical solution, the top of the mounting base slides in contact with the bottom of the mounting ring, and the bottom of the mounting ring away from the bolt has several screw holes, through which the mounting base and the mounting ring are connected together by screws passing through the screw holes.

[0010] As a further improvement to this technical solution, the screw has oppositely oriented threads on the sidewalls near both ends, and the two mounting seats are connected by two threaded screws. During rotation, the screw drives the two mounting seats to move closer to or further away from each other.

[0011] As a further improvement to this technical solution, the upper side of the base is provided with a shell, and through holes are opened on the corresponding side walls of the shell, and the connecting pipeline is located inside the through holes.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This ground source heat pump pipeline interface positioning device involves workers connecting the pipelines together with bolts and nuts, and then placing an installation ring on the pipeline. The installation ring is rotated according to the positions of the bolts and nuts to align the positioning block with them. The installation ring is then connected to a moving assembly, which fixes the installation ring and moves it closer to the bolts and nuts. When the positioning block approaches the bolts and nuts, the worker tightens the positioning block, causing it to fit over the bolts and nuts. Simultaneously, a torsion spring applies a rotational force to the positioning block, restricting the position of the bolts and nuts and reducing loosening caused by their rotation.

[0015] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1 Please see Figure 1 - Figure 4 As shown, the purpose of this embodiment is to provide a ground source heat pump pipeline interface positioning device, including a base 1, two connecting pipelines 3 are connected together by bolts 31 and nuts 32, a housing 11 is provided on the upper side of the base 1, the connection of the connecting pipelines 3 is located inside the housing 11, the housing 11 is assembled together by two housings, through holes are opened on the corresponding side walls of the housing 11, the connecting pipelines 3 are located inside the through holes, a sealing rubber ring is provided between the through holes and the connecting pipelines 3, the gap between the connecting pipelines 3 and the through holes is blocked by the sealing rubber ring, so as to prevent dust from entering the interior of the housing 11 and prevent dust from accumulating inside the housing 11 and affecting the use of the positioning device. At the same time, the sealing rubber ring buffers the friction between the through holes and the connecting pipelines 3, reduces the damage caused by the friction between the connecting pipelines 3 and the through holes, and extends the service life of the connecting pipelines 3. A positioning mechanism 2 is provided on the upper side of the base 1. The positioning mechanism 2 includes a moving component and two limiting components. The moving component connects the two limiting components to the base 1. The moving component drives the two limiting components to move closer to or further away from each other. When the limiting components move to a position close to the bolt 31 and nut 32, the two limiting components press against the connection of the connecting pipe 3. At the same time, the limiting components restrict the position of the bolt 31 and nut 32. After the two connecting pipes 3 are connected, the moving component drives the two limiting components to move closer to the bolt 31 and nut 32, so that the limiting components are located outside the bolt 31 and nut 32. By restricting the position of the bolt 31 and nut 32 by the limiting components, the loosening of the bolt 31 and nut 32 caused by the shaking of the connecting pipe 3 is reduced, thereby extending the fixing time of the bolt 31 and nut 32 to the connection of the two connecting pipes 3 and ensuring the normal use of the two connecting pipes 3.

[0017] refer to Figure 5 - Figure 7 The limiting component includes a mounting ring 23, which consists of two connected semi-circular rings. The mounting ring 23 is slidably sleeved on the outside of the connecting pipeline 3. Several movable grooves are opened on the side of the mounting ring 23 near the bolt 31. Positioning blocks 24 are rotatably connected inside the movable grooves. Several positioning blocks 24 are set in a corresponding position to the bolt 31 and nut 32 on the connecting pipeline 3. A butterfly knob is coaxially fixed to the side of the positioning block 24 away from the bolt 31 through the mounting ring 23. When the operator turns the butterfly knob, it drives the positioning block 24 to rotate. A positioning groove is opened on the side of the positioning block 24 near the bolt 31. The positioning groove matches the cross-sectional shape of the bolt 31 and nut 32. When the bolt 31 and nut 32 are inside the positioning groove, the bolt 31 and nut 32 are in close contact with the inner wall of the positioning groove. A torsion spring is installed between the positioning block 24 and the inner wall of the movable groove. The two ends of the torsion spring are fixedly connected to the side wall of the positioning block 24 and the inner wall of the movable groove, respectively. When the mounting ring 23 moves close to the bolt 31 and nut 32, it stops moving. The operator turns the butterfly knob to rotate the positioning block 24 to store the torsion spring. Then the operator continues to move the mounting ring 23 to put the positioning block 24 on the outside of the bolt 31 and nut 32. At this time, the torsion spring drives the positioning block 24 to rotate, so that it applies a force to the bolt 31 and nut 32 in the tightening direction. The torsion spring and the positioning block 24 slow down the speed of the bolt 31 and nut 32 rotating in the opposite direction, prolonging the time for the bolt 31 and nut 32 to loosen and separate, ensuring the connection effect between the two connecting pipes 3.

[0018] refer to Figure 5The upper side of the base 1 is provided with a sliding groove. The moving component includes a screw 21 rotatably connected inside the sliding groove. One end of the screw 21 passes through the base 1 and is fixedly connected to a hexagonal knob. The operator turns the hexagonal knob with a wrench to make the screw 21 rotate. Two mounting seats 22 are threadedly connected to the screw 21. The side walls of the screw 21 near both ends are provided with threads in opposite directions. The two mounting seats 22 are threadedly connected by two threaded screws 21. During the rotation of the screw 21, the two mounting seats 22 move towards each other or away from each other. The upper side of the mounting base 22 extends through the sliding groove. The top of the mounting base 22 slides in contact with the bottom of the mounting ring 23. The bottom of the mounting ring 23 away from the bolt 31 has several screw holes. The mounting base 22 and the mounting ring 23 are connected together by screws passing through the screw holes. By threading the screws into different screw holes, the tilt angle of the mounting ring 23 on the mounting base 22 is changed, thereby adjusting the position of the positioning block 24 on the mounting ring 23 so that the positioning block 24 corresponds to the position of the bolt 31 and the nut 32. This makes it easy for the positioning block 24 to be sleeved on the outside of the bolt 31 and the nut 32 during the movement of the mounting ring 23. The mounting base 22 drives the mounting ring 23 to move during the movement.

[0019] When using this device: During the installation of connecting pipeline 3, the workers connect the two connecting pipelines 3 together using bolts 31 and nuts 32. Then, the workers assemble the mounting ring 23 so that it is located outside the connecting pipeline 3. The workers rotate the mounting ring 23 so that the positioning block 24 corresponds to the position of the bolts 31 and nuts 32. After the position of the mounting ring 23 is adjusted; The workers connect the mounting ring 23 to the mounting base 22 with screws. Then, the workers turn the screw 21 with a wrench to rotate it, causing the two mounting rings 23 to move closer to the bolt 31 and nut 32. When the mounting rings 23 move to the position close to the bolt 31 and nut 32, the mounting rings 23 stop moving. The operator turns the butterfly knob to make the positioning block 24 rotate. During the rotation, the positioning block 24 stores the torsion spring. When the positioning groove corresponds to the shape of the bolt 31 and nut 32, the positioning block 24 stops rotating. Then, the mounting ring 23 continues to move towards the bolt 31 and nut 32, so that the positioning block 24 is fitted on the outside of the bolt 31 and nut 32. At this time, the torsion spring applies a force to the positioning block 24, bolt 31 and nut 32 in the tightening direction to slow down the speed at which the bolt 31 and nut 32 loosen due to reverse rotation.
