Description

Technical Field

[0001] This utility model relates to the field of ground source heat pump technology, and in particular to a buoyancy-resistant device for underground pipes of ground source heat pumps. Background Technology

[0002] A ground source heat pump is a highly efficient and energy-saving system that utilizes shallow geothermal resources to provide both heating and cooling. Ground source heat pumps achieve heat exchange between the system and the earth through the flow of circulating liquid water or antifreeze with water as the main component in closed underground pipes.

[0003] The prior art disclosure number CN221238004U describes a buoyancy-preventing device for buried pipes. By simultaneously pressing the inner surfaces of both sides of the U-shaped pipe with two sets of tightening components, the device fixes the U-shaped pipe and prevents water or backfill material in the borehole from causing the U-shaped pipe to float up and down during backfilling, thus avoiding deviation in the buried position and improving the fixing effect of the buoyancy-preventing device for buried pipes.

[0004] The shortcoming of the aforementioned existing technology is that it cannot control the horizontal state of the buried pipe. That is, the upper end of the buried pipe opening is always horizontal. If there is a slight deviation, after the buried pipe is fixed by the backfill, the subsequent threaded connection will cause the thread engagement to be unsmooth, resulting in inconvenience in pipe installation.

[0005] Therefore, this application proposes a buoyancy-resistant device for buried pipes of ground source heat pumps. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a buoyancy-resistant device for buried pipes of ground source heat pumps.

[0007] An embodiment of this utility model provides a buoyancy-resistant device for buried pipes of ground source heat pumps, comprising:

[0008] A buoyancy-blocking plate has multiple threaded grooves at its bottom, with bolts threaded into the grooves. A coaxial conical block is fixed to the bottom of each bolt, and the conical block can press against the buried pipe.

[0009] Four support adjustment mechanisms are used to position and level the anti-buoyancy plate. Each support adjustment mechanism includes a screw that passes through the anti-buoyancy plate. A support plate that abuts against the ground is fixed to the bottom of the screw. A fixed cone that can be inserted into the ground is fixed to the bottom of the support plate. A support nut and a positioning nut are threaded onto the screw. The anti-buoyancy plate can be adjusted to a horizontal position by adjusting the support nut and the positioning nut.

[0010] Furthermore, the conical block is welded to the bolt, and the outer wall of the conical block is provided with anti-slip texture.

[0011] Furthermore, the anti-buoyancy plate has four through holes through which the screw can pass.

[0012] Furthermore, two first handles are welded onto the support nut, and the outer walls of the two first handles are covered with a first rubber membrane.

[0013] Furthermore, two second handles are welded onto the positioning nut, and the outer walls of the two second handles are covered with a second rubber membrane.

[0014] Furthermore, a bubble level is installed at the upper end of the anti-buoyancy plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This invention uses the bubble level indicator to precisely adjust the support nut and positioning nut to ensure that the anti-buoyancy plate is absolutely level. This ensures that the upper end of the buried pipe opening is level, providing good conditions for subsequent pipe thread connection and avoiding inconvenience in pipe installation caused by poor thread engagement.

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1-4 As shown in the figure, this utility model embodiment proposes a buoyancy-resistant device for buried pipes of ground source heat pumps, comprising:

[0024] The anti-buoyancy plate 1 is made of high-strength, corrosion-resistant engineering plastics or metal to ensure its long-term stable operation in complex underground environments. Multiple threaded grooves 13 are evenly distributed on the bottom of the anti-buoyancy plate 1. The size and depth of the threaded grooves 13 are precisely designed to ensure a secure connection with the bolts 12.

[0025] The threaded groove 13 is internally threaded with a bolt 12. The bolt 12 is made of high-strength alloy steel and has good tensile and compressive strength. A coaxial tapered block 10 is fixed to the bottom of the bolt 12. The tapered block 10 and the bolt 12 are firmly connected by welding. During the welding process, the welding parameters are strictly controlled to ensure the welding quality and avoid defects such as incomplete welding or missing welding.

[0026] The outer wall of the conical block 10 is provided with anti-slip texture 11, which not only facilitates the rotation of the conical block 10 by construction personnel, thus making it easier to engage the bolt 12 in the threaded groove 13, but also increases the friction between the conical block 10 and the buried pipe when tightening it, preventing the buried pipe from shifting during backfilling. By threading the bolt 12 into different threaded grooves 13, the span between the two conical blocks 10 can be adjusted to accommodate U-shaped pipes of different spans; at the same time, the conical block 10 can also meet the positioning requirements of pre-embedded pipes of various sizes.

[0027] In practice, construction workers can use special tools, such as wrenches with corresponding sockets, to fit onto the conical block 10 and adjust the position of the bolt 12 in the threaded groove 13 by rotating the tool, thereby achieving the tightening and fixing of the buried pipe.

[0028] Four support and adjustment mechanisms are provided for positioning the buoyancy-blocking plate 1 and for adjusting its level. Each support and adjustment mechanism includes a screw 9 that passes through the buoyancy-blocking plate 1. Four through holes are provided on the buoyancy-blocking plate 1, with the diameter of the through holes slightly larger than the diameter of the screw 9 to ensure that the screw 9 can pass smoothly through the through holes while maintaining a certain level of stability. A support plate 4, which is circular or square in design and has a large area, is fixed to the bottom of the screw 9 and rests against the ground. The support plate 4 can evenly distribute the weight of the buoyancy-blocking plate 1 and the buried pipe, improving the stability of the device.

[0029] The bottom of the support plate 4 is fixed with a fixing cone 3 that can be inserted into the ground. The fixing cone 3 is made of high-strength metal and has a sharp tip, which makes it easy to insert into the ground and further enhances the fixing effect of the device.

[0030] The screw 9 is threadedly connected to a support nut 5 and a positioning nut 7. Two first handles 6 are welded to the support nut 5, and the outer walls of the two first handles 6 are coated with a first rubber membrane. The first rubber membrane has good anti-slip properties and a comfortable feel, making it easy for construction personnel to grip and rotate the support nut 5. Two second handles 8 are welded to the positioning nut 7, and the outer walls of the two second handles 8 are coated with a second rubber membrane. The second rubber membrane also has anti-slip and comfortable grip characteristics, making it easy for construction personnel to operate the positioning nut 7.

[0031] The buoyancy-blocking plate 1 can be adjusted to a horizontal position by adjusting the support nut 5 and the positioning nut 7. In the actual adjustment process, the construction personnel first install the four support adjustment mechanisms, pass the screw 9 through the through hole on the buoyancy-blocking plate 1, and make the support plate 4 contact the ground, inserting the fixing cone 3 into the ground. Then, by rotating the first handle 6, the position of the support nut 5 on the screw 9 is adjusted, initially adjusting the height and approximate horizontal state of the buoyancy-blocking plate 1.

[0032] Next, the bubble level 2 is used to test the anti-buoyancy plate 1, and the support nut 5 is further fine-tuned based on the test results. When the anti-buoyancy plate 1 is basically level, the second handle 8 is turned to adjust the positioning nut 7 so that it fits tightly with the support nut 5, and the anti-buoyancy plate 1 is firmly fixed in the current level position.

[0033] Construction workers can precisely adjust the support nut 5 and the positioning nut 7 according to the display of the bubble level 2 to ensure that the anti-buoyancy plate 1 is in an absolutely horizontal state, thereby ensuring that the upper end of the buried pipe opening is in a horizontal state, providing good conditions for subsequent pipe thread connection, and avoiding the problem of inconvenient pipe installation caused by poor thread engagement.

[0034] Before installing the underground pipe, the construction site should be cleaned and leveled to ensure that the ground is firm, flat, and free of debris and obstacles. The four support adjustment mechanisms should be installed in the designed positions so that the support plate 4 is in contact with the ground and the fixing cone 3 is inserted into the ground.

[0035] Then the underground pipe is installed, and after the installation is completed, backfilling is carried out. During the backfilling process, care should be taken to avoid damaging the screw rod 9 and the underground pipe.

[0036] After backfilling, the through hole on the anti-buoyancy plate 1 is fitted over the outside of the screw 9 until the two conical blocks 10 are inserted into the U-shaped pipe. The support nut 5 is adjusted by rotating the first handle 6 to abut against the anti-buoyancy plate 1. The height and approximate horizontal state of the anti-buoyancy plate 1 are initially adjusted. A bubble level 2 is used to check the anti-buoyancy plate 1, and the support nut 5 is further fine-tuned based on the test results to ensure the anti-buoyancy plate 1 is basically horizontal. The positioning nut 7 is adjusted by rotating the second handle 8 to fit tightly with the support nut 5, firmly fixing the anti-buoyancy plate 1 in its current horizontal position, thus ensuring that the U-shaped embedded pipe is horizontal.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
