Description

Technical Field

[0001] The present invention relates to the technical field of ground source heat pumps, and in particular to a flotation prevention device for a buried pipe of a ground source heat pump. Background Art

[0002] A geothermal heat pump is a device that transfers low-grade thermal energy from shallow land to high-grade heat energy by injecting a small amount of high-grade energy (such as electricity). A geothermal heat pump system can provide heating, air conditioning, and domestic hot water, offering multiple uses. A single system can replace two existing boiler and air conditioning systems, allowing for a wide range of applications. Furthermore, the units offer a long service life of over 15 years, are compact and space-saving, have low maintenance costs, and are highly automated, allowing for unmanned operation. A geothermal heat pump is a form of water-source heat pump that uses water as its heat and cold source by exchanging heat with geothermal energy (groundwater, soil, or surface water). In winter, heat from the geothermal energy is extracted to provide indoor heating, with the geothermal energy serving as the "heat source." In summer, heat is extracted from indoor spaces and released into the groundwater, soil, or surface water, with the geothermal energy serving as the "cold source."

[0003] Although the existing technology can effectively prevent the buried pipe from floating up due to the buoyancy of the backfill material, it often has the following problems: during use, the height of the U-shaped buried pipe cannot be adjusted well, which makes it inconvenient to adjust the U-shaped buried pipe later, affecting the use effect of the device.

[0004] In order to solve the above problems, the present application proposes a flotation prevention device for underground pipes of ground source heat pumps. Summary of the Invention

[0014] Preferably, in the above technical solution, a support disc is fixedly sleeved on the surface of the lifting column, which is used to increase the contact area between the lifting column and the ground, thereby improving the stability of the lifting column.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] Now, various exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that: Unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present invention.

[0034] Unless otherwise specified, the experimental methods used in the following examples are all conventional methods. The materials and reagents used, unless otherwise specified, can all be obtained from commercial sources. The equipment used in the experiments, unless otherwise specified, is well-known to those skilled in the art.

[0035] As shown in the figure, the present invention provides a floating prevention device for ground source heat pump buried pipes, including a fixing plate 1. Two support frames 6 are fixedly installed on the fixing plate 1. A threaded rod 7 is rotatably connected inside the two support frames 6. A connecting block 8 is threadedly connected to the surface of the threaded rod 7. Two fixed hollow rods 10 are fixedly installed at the bottom of the connecting block 8. A limiting slideway 9 is opened on the fixing plate 1. The surfaces of the two fixed hollow rods 10 are slidably connected inside the limiting slideway 9. A U-shaped buried pipe 11 is movably sleeved inside each of the two fixed hollow rods 10.

[0036] When adjusting the position of the U-shaped buried pipe 11, rotate the threaded rod 7. Since the two fixed hollow rods 10 are restricted by the limiting slideway 9, the two fixed hollow rods 10 slide inside the limiting slideway 9, and then the U-shaped buried pipe 11 moves along with the two fixed hollow rods 10, which is convenient for adjusting the position of the U-shaped buried pipe 11, and further convenient for correcting the position of the U-shaped buried pipe 11 to prevent deviation.

[0037] Furthermore, a lifting column 2 is slidably connected inside the fixing plate 1, and a plug rod 3 is slidably connected inside the lifting column 2. Through the arrangement of the lifting column 2 and the plug rod 3, it is convenient to fix the fixing plate 1 on the ground, thereby preventing the U-shaped buried pipe 11 from floating, and avoiding the movement of the U-shaped buried pipe 11 and the fixing plate 1 to the greatest extent, improving the fixing effect of the fixing plate 1 and the U-shaped buried pipe 11.

[0038] A support disc 5 is fixedly sleeved on the surface of the lifting column 2. Through the arrangement of the support disc 5, it is convenient to increase the contact area between the lower end of the lifting column 2 and the ground, and then improve the stability of the lifting column 2 during use.

[0039] Furthermore, a fixed plug rod 12 is slidably connected inside the fixing plate 1. A fixed jack 4 is opened on the surface of the lifting column 2. One end of the fixed plug rod 12 is slidably clamped inside the fixed jack 4. A tension spring 13 is movably sleeved on the surface of the fixed plug rod 12. One end of the tension spring 13 close to the fixing plate 1 is fixedly connected to the surface of the fixing plate 1, and the other end of the tension spring 13 far from the fixing plate 1 is fixedly connected to the surface of the fixed plug rod 12.

[0040] Pull the fixed insertion rod 12, so that the fixed insertion rod 12 slides inside the fixed plate 1 and the fixed insertion hole 4, so that one end of the fixed insertion rod 12 is separated from the inside of the fixed insertion hole 4, and at the same time stretch the tension spring 13, so that the lifting column 2 is no longer fixed, and the lifting column 2 slides inside the fixed plate 1. After adjusting the position of the lifting column 2, stop pulling the fixed insertion rod 12, so that the fixed insertion rod 12 is reset by the tension of the tension spring 13, so that the fixed insertion rod 12 is inserted into the fixed insertion hole 4, thereby realizing the fixation of the lifting column 2, facilitating the adjustment of the height of the fixed plate 1, and further facilitating the adjustment of the height of the U-shaped buried pipe 11, so as to facilitate the adjustment of the height of the U-shaped buried pipe 11 according to the use requirements of the U-shaped buried pipe 11.

[0041] Further, a lifting slideway 14 is opened on one side of the fixed hollow rod 10. A lifting rod 15 is slidably connected inside the lifting slideway 14. A limiting column 16 is fixedly installed inside the fixed hollow rod 10. The lifting rod 15 slides on the surface of the limiting column 16. One end of the lifting rod 15 is fixedly installed with a hanging rod 17. The lower end of the hanging rod 17 is fixedly installed with a lifting plate 18. Rolling wheels 25 are rotatably connected inside both ends of the lifting plate 18. A square rod 22 is fixedly installed inside the fixed hollow rod 10. Two clamping plates 19 are slidably connected on the surface of the square rod 22. Rubber pads 23 are fixedly installed on the opposite sides of the two clamping plates 19. Extrusion grooves 20 are opened on the opposite sides of the two clamping plates 19. Both ends of the lifting plate 18 are slidably connected inside the two extrusion grooves 20 respectively. The two rolling wheels 25 are respectively rollingly connected inside the two extrusion grooves 20. Two return springs 21 are movably sleeved on the surface of the square rod 22. The opposite ends of the two return springs 21 are respectively fixedly connected to the two clamping plates 19. The opposite ends of the two return springs 21 are both fixedly connected to the inside of the fixed hollow rod 10. A limiting baffle 24 is fixedly sleeved on the square rod 22.

[0042] Pull up the lifting rod 15, causing the lifting rod 15 to move upward on the surface of the limiting column 16 and inside the lifting slideway 14, thereby driving the hanging rod 17 and the lifting plate 18 to move upward. Since the shapes of the two extrusion grooves 20 are both inclined, when the two lifting plates 18 move upward, they squeeze the two clamping plates 19 and the two extrusion grooves 20, causing the two clamping plates 19 to move away from each other on the surface of the square rod 22 and squeezing the two return springs 21. Then insert the U-shaped buried pipe 11 into the inside of the fixed hollow rod 10. As a result, the U-shaped buried pipe 11 will be blocked by the limiting baffle 24, and then stop pulling the lifting rod 15. The two clamping plates 19 are reset by the elastic force of the two return springs 21, causing the two clamping plates 19 to move relatively, so that the two rubber pads 23 clamp the surface of the U-shaped buried pipe 11, facilitating the fixation of the U-shaped buried pipe 11, improving the convenience of fixing the U-shaped buried pipe 11, preventing the U-shaped buried pipe 11 from sliding, and facilitating the assembly of the device.

[0043] Through the setting of the limiting baffle 24, it is convenient to limit the depth of insertion of the U-shaped buried pipe 11 into the fixed hollow rod 10.

[0044] Working principle:

[0045] Rotate the threaded rod 7. Since the two fixed hollow rods 10 are restricted by the limiting slideway 9, the two fixed hollow rods 10 slide inside the limiting slideway 9, causing the U-shaped buried pipe 11 to move along with the two fixed hollow rods 10, facilitating the adjustment of the position of the U-shaped buried pipe 11.

[0046] Through the setting of the lifting column 2 and the insertion rod 3, it is convenient to fix the fixing plate 1 on the ground, thereby preventing the U-shaped buried pipe 11 from floating.

[0047] Pull the fixed insertion rod 12, causing the fixed insertion rod 12 to slide inside the fixing plate 1 and the fixed insertion hole 4. One end of the fixed insertion rod 12 is disengaged from the inside of the fixed insertion hole 4, and at the same time, the tension spring 13 is stretched. Then the lifting column 2 is no longer fixed. The lifting column 2 slides inside the fixing plate 1. After adjusting the position of the lifting column 2, stop pulling the fixed insertion rod 12. The fixed insertion rod 12 is reset by the tension of the tension spring 13, causing the fixed insertion rod 12 to snap into the fixed insertion hole 4, thereby realizing the fixation of the lifting column 2 and facilitating the adjustment of the height of the fixing plate 1.

[0048] Pull the lifting rod 15 upward, so that the lifting rod 15 moves upward on the inner surface of the lifting slideway 14 and the surface of the limiting upright post 16, thereby driving the hanging rod 17 and the lifting plate 18 to move upward. Since the shapes of the two extrusion grooves 20 are both inclined, when the two lifting plates 18 move upward, they will extrude the two clamping plates 19 and the two extrusion grooves 20, causing the two clamping plates 19 to move away from each other on the surface of the square rod 22 and extruding the two return springs 21. Then insert the U-shaped buried pipe 11 into the inside of the fixed hollow rod 10. At this time, the U-shaped buried pipe 11 will be blocked by the limiting baffle 24, so stop pulling the lifting rod 15. The two clamping plates 19 are reset by the elastic force of the two return springs 21, causing the two clamping plates 19 to move relatively, so that the two rubber pads 23 clamp the surface of the U-shaped buried pipe 11, which is convenient for fixing the U-shaped buried pipe 11.

[0049] Although the present invention has been disclosed above with embodiments, it is not intended to limit the present invention.

Therefore, the protection scope of the present invention is defined by the claims and their equivalent forms.
