[0024] 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.
[0025] Example: Please refer to Figure 1-4 A pipe fixing structure for use in water conservancy and hydropower includes two sets of upper limit rings 1, a lower limit ring 2 is provided below the two sets of upper limit rings 1, a connecting seat 3 is fixedly connected to the bottom end of the lower limit ring 2, a base 4 is fixedly connected to the bottom end of the connecting seat 3, two sets of upper connecting plates 5 are fixedly connected to the front and rear ends of the upper limit ring 1, two sets of lower connecting plates 6 are fixedly connected to the front and rear ends of the lower limit ring 2, and an adjustable anti-loosening structure is provided at the top of the upper connecting plate 5.
[0026] Please see Figure 1-4 The pipe fixing structure used for water conservancy and hydropower also includes an adjustable anti-loosening structure. The adjustable position fixing structure includes a first nut 7, which is fixedly connected to the top of the upper connecting plate 5. A first screw 8 is movably connected inside the first nut 7. A first limiting hole 9 is opened on the right side of the first nut 7. A second screw 10 is movably connected inside the first limiting hole 9. A first handle 11 is fixedly connected to the right side of the second screw 10. A first limiting post 12 is fixedly connected to the left side of the second screw 10. A second limiting hole 13 is opened on the left side of the first nut 7. A third screw 14 is movably connected inside the second limiting hole 13. A second handle 15 is fixedly connected to the left side of the third screw 14. A second limiting post 16 is fixedly connected to the right side of the third screw 14.
[0027] Two sets of upper connecting plates 5 are arranged symmetrically, and two sets of lower connecting plates 6 are arranged symmetrically. The outer dimensions of the first screw 8 match the dimensions of the first nut 7, and the first screw 8 can move up and down in the first nut 7. The outer dimensions of the second screw 10 match the first limiting hole 9, and the second screw 10 can move left and right under the action of the first handle 11. The outer dimensions of the third screw 14 match the second limiting hole 13, and the third screw 14 can move left and right under the action of the second handle 15.
[0028] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, in use, the pipe is placed on the top of the lower limiting ring 2, and then the upper limiting ring 1 is placed on top of the pipe. The pipe is fixed by turning the two sets of first screws 8 through the first nut 7. Then, by manually turning the first handle 11, the first handle 11 drives the second screw 10 to move left and right in the first limiting hole 9, so that the first limiting post 12 and the first screw 8 are tightly fitted. By manually turning the second handle 15, the second handle 15 drives the third screw 14 to move left and right in the second limiting hole 13, so that the second limiting post 16 and the first screw 8 are tightly fitted. This fixes the first screw 8 and the first nut 7 in place, thus preventing the pipe from becoming loose.
[0029] A first movable plate 17 is fixedly connected to the right side of the left connecting seat 3, and a second movable plate 18 is fixedly connected to the left side of the right connecting seat 3. A second nut 20 is fixedly connected to the bottom end of the first movable plate 17, and a fourth screw 19 is movably connected inside the second nut 20. The first movable plate 17 and the second movable plate 18 can rotate at an angle, and the fourth screw 19 can move up and down inside the second nut 20.
[0030] Specifically, such as Figure 1 As shown, when the two pipes are connected at an angle, the pipes are relatively fragile. In use, the angle between the first movable plate 17 and the second movable plate 18 is adjusted, and the fourth screw 19 passes through the second nut 20 to fix the pipes, thereby achieving the fixation of the two pipes installed at an angle.
[0031] Two sets of fixed plates 22 are fixedly connected to the top of the two sets of upper limit rings 1. Two sets of support seats 21 are movably connected above the two sets of fixed plates 22. Three sets of second movable columns 24 are fixedly connected to the top of the two sets of fixed plates 22 respectively. Three sets of first movable columns 23 are fixedly connected to the bottom of the two sets of support seats 21 respectively. Springs 25 are sleeved on the outside of the three sets of first movable columns 23. The outer diameter of the second movable column 24 matches the inner diameter of the first movable column 23. The second movable column 24 and the first movable column 23 can move up and down.
[0032] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, in use, a fixing plate 22 is fixedly connected to the top of the upper limit ring 1, and three sets of second movable columns 24 are fixedly connected to the top of the fixing plate 22. Three sets of first movable columns 23 are fixedly connected to the bottom of the support plate. The positions and dimensions of the first movable columns 23 and the second movable columns 24 are matched. A spring 25 is sleeved on the outside of the first movable column 23, thereby achieving effective buffering of the pressure above and thus protecting the pipeline.
[0033] Working Principle: In use, this invention first places the pipe at the top of the lower limiting ring 2, then covers the top of the pipe with the upper limiting ring 1. The pipe is then fixed by turning the two sets of first screws 8 through the first nut 7. Next, manually turning the first handle 11 causes the second screw 10 to move left and right within the first limiting hole 9, tightly engaging the first limiting post 12 with the first screw 8. Manually turning the second handle 15 causes the third screw 14 to move left and right within the second limiting hole 13, tightly engaging the second limiting post 16 with the first screw 8. This fixes the first screw 8 and the first nut 7 in place, preventing the pipe from leaking out. In the case of loosening, and secondly, when the two pipes are connected at an angle, the pipes are relatively fragile. By adjusting the angle between the first movable plate 17 and the second movable plate 18, and fixing it by passing the fourth screw 19 through the second nut 20, the two pipes can be fixed at an angle. At the same time, by fixing the top of the upper limit ring 1 with a fixing plate 22, and fixing the top of the fixing plate 22 with three sets of second movable columns 24, and fixing the bottom of the support plate with three sets of first movable columns 23, the positions and dimensions of the first movable columns 23 and the second movable columns 24 are matched. A spring 25 is sleeved on the outside of the first movable column 23, thereby effectively buffering the pressure from above and protecting the pipes.
[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
