Description

Technical Field

[0001] This utility model relates to the technical field of pipeline laying devices, specifically to a laying device for an underground heat exchanger of a ground source heat pump. Background Technology

[0002] Ground source heat pumps are air conditioning systems based on underground heat sources. By burying heat exchange pipes underground, they can extract underground heat sources and deliver heat energy into buildings through components such as compressors to achieve heating. Through conversion, they can also achieve cooling effects, making them an environmentally friendly and energy-saving air conditioning system.

[0003] Ground source heat pumps mainly transport underground heat sources through heat exchange pipes. Therefore, the pipes need to be buried underground, usually by manual or mechanical installation. However, both methods have drawbacks. Manual installation is inefficient and has a high error rate, while mechanical installation cannot be carried out during the process, which affects the efficiency of drilling.

[0004] The current burial process lacks auxiliary equipment; instead, the pipes are directly inserted into pre-drilled holes or pits. During the pipe laying process, the pipes are prone to displacement, which directly affects subsequent use. Therefore, a burial device for a ground source heat pump underground heat exchanger is proposed. Utility Model Content

[0005] In view of the deficiencies in the existing technology, this utility model provides a burial device for underground heat exchangers of ground source heat pumps to improve the verticality of the pipes during installation and avoid affecting the later use of the pipes due to deviation.

[0006] This utility model provides a burial device for an underground heat exchanger of a ground source heat pump, including a positioning plate. A groove is formed in the middle of one side wall of the positioning plate. A stud is rotatably connected in the groove. The stud has a multi-segment structure, and each segment has a bidirectional thread structure. Two movable collars are sleeved on each segment of the stud through the bidirectional thread. A clamping plate is fixedly connected to one side wall of each movable collar. An arc-shaped groove is formed on the opposite side walls of the two clamping plates. A pipe is inserted between each pair of clamping plates.

[0007] As a preferred technical solution of this utility model, a mounting box is detachably connected to the middle of one side wall of the positioning plate, a motor is detachably connected inside the mounting box, the output end of the motor extends into the slide groove and is detachably connected to one end of the stud, a ball bearing is uniformly rotated inside the arc groove, the arc of the arc groove corresponds to the pipe, and the clamping plate moves along the slide groove through a movable collar.

[0008] As a preferred technical solution of this utility model, the bottom edge of the positioning plate is provided with a slot, a slider is snapped into the slot, one end of the slider is fixedly connected to a sleeve, the sleeve is cylindrical in shape, and an anti-slip pad is fixedly connected to the inner wall of the sleeve.

[0009] As a preferred technical solution of this utility model, a pin is fixedly connected in the middle of the bottom side wall of the anti-slip mat. The pin has a conical structure. One end of the pipe that passes through the arc groove is inserted into the sleeve. The anti-slip mat is located between every two clamps.

[0010] As a preferred technical solution of this utility model, a reinforcing plate is fixedly connected to the lower edge of the side of the positioning plate away from the slide groove. The reinforcing plate and the positioning plate are at right angles. A wedge plate is fixedly connected to the corner of the reinforcing plate and the positioning plate. The reinforcing plate is threaded to the ground.

[0011] As can be seen from the above technical solution, the specific effect of the burial device for the underground heat exchanger of the ground source heat pump provided by this utility model is as follows: the positioning plate is placed on the edge of the drilled hole or the excavated pit, and then the pipe is inserted between the two corresponding clamps. This can limit the pipe and ensure that the pipe can move vertically up and down along the clamps. This can avoid the pipe from deviating during the pipe laying process, which would cause problems with the pipe and affect its later use. The rotating connecting ball on the arc groove can ensure the smooth movement of the pipe. Attached Figure Description

Detailed Implementation

[0017] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0018] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0019] like Figure 1-3 As shown, the burial device for a ground source heat pump underground heat exchanger in this embodiment includes a positioning plate 1. A groove 3 is provided in the middle of one side wall of the positioning plate 1. A stud 10 is rotatably connected in the groove 3. The stud 10 has a multi-segment structure, and each segment is provided with a bidirectional thread structure. Two movable collars 11 are sleeved on each segment of the stud 10 through the bidirectional thread. A clamping plate 4 is fixedly connected to one side wall of each movable collar 11. An arc-shaped groove 12 is provided on the opposite side walls of the two clamping plates 4. A pipe 5 is inserted between each pair of clamping plates 4.

[0020] A mounting box 8 is detachably connected to the middle of one side wall of the positioning plate 1. A motor 9 is detachably connected inside the mounting box 8. The output end of the motor 9 extends into the slide groove 3 and is detachably connected to one end of the stud 10. A ball bearing 13 is evenly rotated inside the arc groove 12. The arc of the arc groove 12 corresponds to the pipe 5. The clamping plate 4 moves along the slide groove 3 via the moving collar 11. A reinforcing plate 2 is fixedly connected to the lower edge of the side of the positioning plate 1 away from the slide groove 3. The reinforcing plate 2 and the positioning plate 1 are at right angles. A wedge plate is fixedly connected to the corner of the reinforcing plate 2 and the positioning plate 1. The reinforcing plate 2 is threaded to the ground.

[0021] The preferred technical solution in this embodiment is as follows: the starter motor 9 drives the stud 10 to rotate, and through the principle of threaded connection, drives multiple pairs of movable collars 11 to move, thereby driving the clamping plate 4 to clamp and limit the pipe 5. The clamping plate 4 can limit the vertical movement of the pipe 5, thus ensuring that the pipe 5 will not deviate during the lowering process, ensuring that the pipe 5 is lowered vertically into the corresponding borehole or excavated pit, and ensuring that the pipe 5 can smoothly absorb and transport the underground heat source. In addition, a ball bearing 13 is rotatably connected on the arc groove 12, which ensures that the pipe 5 can move smoothly in the arc groove 12 while ensuring the limitation of the pipe 5.

[0022] The bottom edge of the positioning plate 1 has a slot 6, and a slider 14 is snapped into the slot 6. One end of the slider 14 is fixedly connected to a sleeve 7. The sleeve 7 is cylindrical and an anti-slip pad 16 is fixedly connected to the inner wall of the sleeve 7. A pin 15 is fixedly connected to the middle of the bottom side wall of the anti-slip pad 16. The pin 15 is conical. One end of the pipe 5 that passes through the arc groove 12 is inserted into the sleeve 7. The anti-slip pad 16 is located between every two clamping plates 4.

[0023] A preferred technical solution in this embodiment is as follows: a slot 6 is opened at the bottom edge of the positioning plate 1, and a sleeve 7 is fixedly connected in the slot 6 by a slider 14. As the pipe 5 descends, its bottom end will be inserted into the sleeve 7. As the pipe 5 continues to descend, the slider 14 will disengage from the slot 6, thereby pushing the sleeve 7 into the pit. When it descends to the bottom, the pin 15 will be inserted into the bottom of the pit. The sleeve 7 and the pin 15 can ensure the stability of the pipe 5 and improve the anti-tilting effect of the pipe 5.

[0024] The equipment is used as follows: First, place the positioning plate 1 on the edge of the corresponding pit. Then, fix the positioning plate 1 to the ground by passing screws through the reinforcing plate 2. Next, place the pipe 5 between the two corresponding clamping plates 4. Then, start the motor 9 in the mounting box 8 to drive the stud 10 to rotate. As the stud 10 rotates, it drives the two corresponding moving collars 11 to move along the stud 10 through the threaded connection, thereby driving the clamping plates 4 to clamp and position the pipe 5. Then, move the pipe 5 downward. As the pipe 5 descends, its bottom end will be inserted into the sleeve 7. As the pressure increases, the slider 14 will be pushed out of the slot 6. Finally, insert the pin 15 into the bottom of the pit to provide support for the pipe 5 and ensure the vertical stability of the pipe 5. During the descent, the pipe 5 will be restricted by the clamping plates 4 to prevent the pipe 5 from shifting during the descent.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
