Description

Technical Field

[0001] The present invention relates to the technical field of pipe clamp devices, and in particular to an adjustable ground source heat pump pipe clamp. Background Art

[0002] Ground source heat pump pipes are used to transport heat source media buried underground. The use of ground source heat pump pipes requires the use of pipe clamps to stably fix them underground to avoid vibration caused by the heat source media entering the pipe body, which makes the pipe body unstable.

[0003] Existing pipe clamps are generally composed of two semicircular clamps, which are clamped on the surface of the pipe body with two semicircular clamps and then fastened with bolts. They are easy to use and have a simple structure. However, although the existing pipe clamps can achieve stable installation of the pipe body, there is a large clamping force between the pipe clamp and the pipe body. When the medium flows into the pipe body, the pipe body will shake, and there will be a large friction between the pipe body and the pipe clamp, which will cause the insulation layer on the surface of the pipe clamp to wear. When the wear of the insulation layer gradually increases, a large gap will exist between the pipe clamp and the pipe body, causing the pipe clamp to gradually loosen, thereby affecting the stability of the pipe body. In addition, the ground source heat pump pipe body heats up when there is a medium and cools down when there is no medium. Under the action of thermal expansion and contraction, the insulation layer on the surface of the pipe body is easy to fall off, further increasing the possibility of a gap between the pipe body and the pipe clamp. Therefore, an adjustable ground source heat pump pipe clamp is proposed to solve the above problems. Summary of the Invention

[0028] The upper clamping plate 22, the lower clamping plate 14, the locking screw 23 and the locking nut cooperate with each other to achieve the clamping function of the pipe body 1. By providing the moving rod 4, the compensation component and the limit component, the pressure of the medium inside the pipe body 1 is used to move the moving rod 4 downward, thereby causing the compensation component and the limit component to cooperate with each other, so that the lower clamping plate moves up and fits tightly against the surface of the pipe body 1, thereby compensating for the gap between the lower clamping plate 14 and the pipe body 1 caused by the wear of the insulation layer on the surface of the pipe body 1.

[0029] The tube body 1 and the lower clamping plate 14 are provided with aligned through-holes, the outer tube 3 is fixedly connected to the through-hole of the tube body 1, the through-hole of the lower clamping plate 14 is slidably connected to the outer tube 3, and a support plate 2 is provided below the lower clamping plate 14. A guide hole is provided at the center of the support plate 2, and the outer tube 3 is fixedly connected to the guide hole. The support plate 2 can support the outer tube 3, and thus support the compensation component and the limit component;

[0030] A movable through groove is provided on the surface of the outer tube 3, and a limiting component symmetrical to the movable through groove is provided on the surface of the outer tube 3, and a compensation component is provided between the limiting components;

[0031] The setting of the limit assembly allows the linkage gear 13 to rotate only in one direction, and thus the lower clamping plate 14 can only move upward and not downward, ensuring that the lower clamping plate 14 can continuously compensate for the gap caused by wear of the insulation layer, thereby ensuring the stability of the pipe clamp in clamping and fixing the pipe body 1.

[0032] The bottom end of the support plate 2 is fixedly connected to the support leg 8, the top of the support plate 2 is provided with a guide groove, the inner wall of the guide groove is provided with a limit slide groove 11, a push plate 6 is provided in the guide groove, and the two side surfaces of the push plate 6 are fixedly connected with limit sliders 7 adapted to the limit slide groove 11. The limit slide groove 11 cooperates with the limit slider 7 to ensure that the push plate 6 can slide stably, and the push plate 6 can lift the linkage tooth plate 5 through the trapezoidal block 12, and then lift the lower splint 14.

[0033] Furthermore, a roller is provided at the top of the push plate 6 , and a threaded barrel 10 is fixedly connected to the bottom end of the push plate 6 , and a bidirectional screw 9 is threadedly connected to the inner side of the threaded barrel 10 .

[0034] Further benefits are achieved: the setting of the roller can reduce the friction between the push plate 6 and the inclined surface of the trapezoidal block 12, and the bidirectional screw 9 and the threaded barrel 10 can drive the push plates 6 to move toward each other, providing power for the movement of the push plates 6.

[0035] Furthermore, a moving rod 4 is slidably connected to the inner side of the outer tube 3 , a surface of the moving rod 4 is fixedly connected to a plurality of meshing teeth, and the top end of the moving rod 4 extends to the interior of the tube body 1 .

[0036] Further benefits are achieved: the moving rod 4 can move downward under the pressure of the medium inside the tube body 1, thereby causing the linkage gear 13 to rotate, and then the linkage gear plate 5 drives the lower clamping plate 14 to move upward, so that the lower clamping plate 14 moves upward to achieve a compensation function.

[0037] Furthermore, the top end of the moving rod 4 is fixedly connected to an elastic membrane 15 , and the edge of the elastic membrane 15 is fixedly connected to the inner wall of the tube body 1 .

[0038] Further benefits are as follows: the elastic membrane 15 can perform the sealing function of the through-port and at the same time increase the force-bearing area of ​​the top end of the moving rod 4 , so that the medium in the tube body 1 generates a greater downward pressure on the moving rod 4 .

[0039] Furthermore, the limiting assembly includes a circular box 16 fixedly connected to the surface of the outer tube 3, a groove 1601 opened on the inner wall of the circular box 16, a limiting tooth 19 slidably connected to the inside of the groove 1601, a connecting shaft 21 rotatably connected to the inner wall of the circular box 16, and a turntable 17 fixedly connected to the surface of the connecting shaft 21.

[0040] Further benefits are achieved: with the cooperation of the helical teeth 20 and the limit teeth 19, the turntable 17 can rotate in one direction, and then the linkage gear 13 can rotate in one direction, so that the lower splint 14 can only move upward, ensuring the stability of the lower splint 14 after compensation, thereby realizing the continuous compensation function.

[0041] Furthermore, a connecting spring 18 is fixedly connected between the limiting teeth 19 and the inner wall of the groove 1601 , and a plurality of oblique teeth 20 are distributed in a circumferential manner on the surface of the rotating disk 17 .

[0042] A further advantage is that the helical teeth 20 cooperate with the limiting teeth 19 and the connecting spring 18 so that the turntable 17 can only rotate in one direction, thereby ensuring the limiting function of the limiting assembly.

[0043] Furthermore, the compensation assembly includes a linkage gear 13 fixedly connected to one end of the connecting shaft 21 and a linkage tooth plate 5 fixedly connected to the bottom end of the lower clamping plate 14, and the linkage gear 13 is engaged with the linkage tooth plate 5 and the meshing teeth.

[0044] Further benefits are achieved: the compensation component can move the lower clamping plate 14 upward when the movable rod 4 moves downward, thereby compensating for the gap caused by the wear of the insulation layer and ensuring the stability of the pipe clamp in clamping the pipe body 1.

[0045] Furthermore, a trapezoidal block 12 is fixedly connected to the bottom end of the linkage tooth plate 5 , and the inclined surface of the trapezoidal block 12 faces the roller.

[0046] Further benefits are achieved: the trapezoidal block 12 moves upward under the squeezing action of the push plate 6, thereby pushing the linkage tooth plate 5 upward, adjusting the position height of the lower clamping plate 14, making it convenient to clamp and fix the pipe body 1 with different diameters, and at the same time providing clamping force for the clamping of the lower clamping plate 14.

[0047] When the present invention is in use, by rotating the bidirectional screw 9, the threaded barrel 10 drives the push plate 6 to move toward each other, and the push plate 6 squeezes the inclined surface of the trapezoidal block 12, so that the trapezoidal block 12 drives the linkage tooth plate 5 to move upward, and the linkage tooth plate 5 drives the lower clamping plate 14 to move upward, and the height of the lower clamping plate 14 is adjusted to facilitate the application of pipe bodies 1 with different diameters. The pipe body 1 is placed between the lower clamping plate 14 and the upper clamping plate 22, and then the locking screw 23 is matched with the locking nut to achieve the clamping and fixing function of the pipe body 1;

[0048] When the insulation layer on the surface of the pipe body 1 is worn for a long time and becomes thinner, a gap is generated between the lower clamping plate 14 and the pipe body 1 (the upper clamping plate 22 is located above the pipe body 1. When wear occurs between the pipe body 1 and the upper clamping plate 22, the upper clamping plate 22 is caused by its own gravity to When the gear 13 is in the open position, the gear 13 is in the open position, and the gear 13 is in the open position, so that the gear 13 can not move downwards, and the gear 13 can not move downwards, so that the gear 13 can not move downwards, and the gear 13 can not move upwards, so that the gear 13 can not move downward ... upwards, so that the gear 13 can not move upwards, so that the gear 13 can not move downwards, so that the gear 13 can not move downwards, so that the gear 13 can not move downwards, so that the gear 13 can not move downwards, so that the gear 13 can not move upwards, so that the gear 13 can not move
