Description

Technical Field

[0001] This utility model relates to the field of pipeline protection technology, specifically a protective cover for pipelines in water conservancy projects. Background Technology

[0002] Water conservancy project pipeline protective covers are protective structures designed to address the problems of exposed or shallowly buried water transmission pipelines being susceptible to rockfall impacts, siltation, and environmental erosion.

[0003] Nowadays, protective covers are usually fixed to a base and then limited by a fixing structure. However, the fixing structure cannot be adjusted. After installation, maintenance or replacement of pipes requires the entire structure to be completely disassembled, which is time-consuming, labor-intensive, and increases costs. Utility Model Content

[0004] The purpose of this utility model is to provide a protective cover for water conservancy engineering pipelines, so as to solve the problems mentioned in the background art, such as the inability to adjust the fixed structure of the protective cover for water conservancy engineering pipelines, the need for complete disassembly for pipeline maintenance, and the time-consuming, labor-intensive and costly process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a protective cover for a water conservancy engineering pipeline, comprising a base plate, a fixing plate fixedly connected to the surface of the base plate, reinforcing ribs fixedly connected to both sides of the bottom end of the fixing plate, a rotating shaft rotatably connected to the surface of the fixing plate, a handle fixedly connected to one end of the rotating shaft, a transmission shaft fixedly connected to the end of the rotating shaft away from the handle, a fixing shaft fixedly connected to the surface of the fixing plate, a limit block slidably connected to the surface of the fixing shaft, a base fixedly connected to the upper surface of the base plate, a lower protective cover movably connected to the surface of the base, an upper protective cover movably connected to the upper surface of the lower protective cover, a buffer layer movably connected to the inner surfaces of the lower and upper protective covers, a pipeline body movably connected to the inner surface of the buffer layer, a connecting rod slidably connected to the sides of the lower and upper protective covers, a buffer rib fixedly connected to the upper surface of the upper protective cover, and fixing bolts fixedly connected to the surfaces of the lower and upper protective covers.

[0006] Preferably, the fixed shaft is provided in two sets, and the surface of the limiting block is provided with two sets of circular through holes, and the fixed shaft is disposed in the circular through holes of the limiting block.

[0007] Preferably, the surface of the limiting block is provided with a threaded through hole, and the end of the transmission shaft away from the rotation shaft is disposed in the threaded through hole of the limiting block.

[0008] Preferably, one side of the limiting block is arc-shaped and corresponds to the surface curvature of the lower protective cover and the upper protective cover.

[0009] Preferably, the lower protective cover and the upper protective cover have semi-circular cross-sections, and the lower protective cover and the upper protective cover have the same shape and size.

[0010] Preferably, the buffer layer is annular and has a deformable structure.

[0011] Preferably, the buffer ribs are provided in eight sets, the buffer ribs are crescent-shaped, and the arc of the lower side of the buffer ribs is equal to the surface arc of the upper protective cover. The width of the middle part of the buffer ribs is greater than the width of the two ends.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The protective cover for the pipeline in this water conservancy project can drive the rotating shaft and the transmission shaft to rotate by turning the handle. The limit block can be adjusted to make forward and backward horizontal displacement on the transmission shaft, so that the limit block can fix the lower protective cover and the upper protective cover. It is convenient to disassemble when inspecting the pipeline without having to remove the entire structure, saving time, effort and reducing costs.

[0014] 2. The protective cover for the water conservancy project pipeline can effectively protect the pipeline by setting a buffer layer. At the same time, the buffer layer is deformable and can still fit tightly to the pipeline when the pipeline expands and contracts due to thermal changes. By setting buffer ribs, it can effectively buffer the impact of falling rocks and guide the falling rocks to both sides of the pipeline, reducing the frontal impact, protecting the pipeline, and extending its service life.

[0021] 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.

[0022] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] A protective cover for a water conservancy pipeline includes a base plate 1, which is generally rectangular and flat. Fixing blocks are fixedly connected to the four corners of the base plate 1. Through holes are formed in the fixing blocks, and fixing posts are installed within these holes to fix the entire device to the ground. A fixing plate 2 is fixedly connected to the surface of the base plate 1. The fixing plate 2 is generally rectangular with rounded ends at the top. Reinforcing ribs 3 are fixedly connected to both sides of the bottom end of the fixing plate 2 to improve its stability. Through holes are formed on the surface of the fixing plate 2, and a rotating shaft 4 is rotatably connected inside these holes. The rotating shaft 4 can rotate but is fixed horizontally and cannot move forward or backward. A handle 5 is fixedly connected to one end of the rotating shaft 4, and a drive shaft 6 is fixedly connected to the end of the rotating shaft 4 away from the handle 5. The drive shaft 6 has threads. The length of the rotating shaft 4 is greater than the thickness of the fixing plate 2, and both ends of the rotating shaft 4 protrude from the surface of the fixing plate 2. A fixing shaft 7 is fixedly connected to the surface of the fixing plate 2. The surface of the base plate 7 is slidably connected to a limiting block 8. The upper surface of the base plate 1 is fixedly connected to a base 9. The upper part of the base 9 is arc-shaped, and the arc is the same as the arc of the lower protective cover 10. The surface of the base 9 is movably connected to the lower protective cover 10. The upper surface of the lower protective cover 10 is movably connected to the upper protective cover 11. The inner surfaces of the lower protective cover 10 and the upper protective cover 11 are movably connected to a buffer layer 12. The inner surface of the buffer layer 12 is movably connected to the pipe body 13. The sides of the lower protective cover 10 and the upper protective cover 11 are provided with four sets of through holes that penetrate the lower protective cover 10 and the upper protective cover 11 longitudinally. The through holes are slidably connected to a connecting rod 14. The upper surface of the upper protective cover 11 is fixedly connected to a buffer rib 15. The surfaces of the lower protective cover 10 and the upper protective cover 11 are fixedly connected to a fixing bolt 16. The above structure together realizes the flexible installation and disassembly of the pipe, while reducing the impact on the pipe and extending its service life.

[0024] Furthermore, two sets of fixed shafts 7 are provided, and the fixed shafts 7 are symmetrically distributed vertically around the transmission shaft 6. Two sets of circular through holes are opened on the surface of the limiting block 8, and the fixed shaft 7 is set in the circular through holes of the limiting block 8. A limiting piece is provided on the part of one end of the fixed shaft 7 away from the fixed plate 2. The size of the limiting piece is larger than the circular through hole on the limiting block 8. The above structure allows the limiting block 8 to slide horizontally back and forth on the fixed shaft 7.

[0025] Furthermore, the surface of the limiting block 8 is provided with a threaded through hole, and the end of the drive shaft 6 away from the rotating shaft 4 is set in the threaded through hole of the limiting block 8. The limiting block 8 is connected to both the drive shaft 6 and the fixed shaft 7. The above structure together realizes that the rotation of the drive shaft 6 can drive the limiting block 8 to move horizontally back and forth, thereby enabling the limiting block 8 to limit the lower protective cover 10 and the upper protective cover 11.

[0026] Furthermore, one side of the limiting block 8 is arc-shaped and corresponds to the surface curvature of the lower protective cover 10 and the upper protective cover 11, so that the limiting block 8 can completely fit the surface of the lower protective cover 10 and the upper protective cover 11 to limit them and prevent them from shaking.

[0027] Furthermore, the lower protective cover 10 and the upper protective cover 11 have semi-circular cross sections, and the lower protective cover 10 and the upper protective cover 11 have the same shape and size. The lower protective cover 10 and the upper protective cover 11 can be fitted together to form a hollow cylinder, which can carry the buffer layer 12 and the pipe body 13 inside.

[0028] Furthermore, the buffer layer 12 is annular and has a deformable structure. The material can be memory foam or other high-resilience materials, so that the pipe body 13 can be completely confined inside the lower protective cover 10 and the upper protective cover 11. At the same time, it prevents the pipe body 13 from being squeezed by thermal expansion and contraction, causing rupture and leakage. When the pipe size recovers, the size of 12 also recovers, ensuring that it still has the ability to deform after compression.

[0029] Furthermore, eight sets of buffer ribs 15 are provided, evenly distributed on the upper surface of the upper protective cover 11. The buffer ribs 15 are crescent-shaped, and the arc of the lower side of the buffer ribs 15 is equal to the arc of the surface of the upper protective cover 11. The width of the middle part of the buffer ribs 15 is greater than the width of the two ends. The buffer ribs 15 on the upper protective cover 11 are generally high in the middle and low on both sides. This creates an inclined angle that can guide the falling rocks above to both sides of the pipe, avoiding impact on the front of the pipe.

[0030] Working principle: During installation, the operator rotates handle 5 to drive the rotating shaft 4 and transmission shaft 6 to rotate. The limiting block 8 is threaded onto the transmission shaft 6, while the fixing shaft 7 restricts the rotation of the limiting block 8, so that the limiting block 8 can only move horizontally back and forth. Rotate the limiting block 8 away from the base 9. At this time, place the lower protective cover 10 on the base 9, then put the buffer layer 12 on the pipe body 13 and place it on the lower protective cover 10. Place the upper protective cover 11 on the buffer layer 12 and align the fixing bolts 16 on the upper protective cover 11 with the fixing bolts 16 on the lower protective cover 10. Fix them with bolts. During the bolt tightening process, the buffer layer 12 is squeezed and deformed, tightly fitting the lower protective cover 10, the upper protective cover 11 and the pipe body 13, fixing the three together. At this time, the operator rotates handle 5 to move the limiting block 8 horizontally to fit the lower protective cover 10 and the upper protective cover 11, limiting the lower protective cover 10 and the upper protective cover 11 on the base 9, completing the installation. When pipeline maintenance is required, repeat the above process to remove the pipeline for repair or replacement and then reinstall it.

[0031] When rocks or other heavy objects fall, the shape of the buffer rib 15 is high in the middle and low on both sides with a certain angle of inclination. When impacted by falling rocks, the above structure can deflect the direction of gravity of the falling rocks to both sides of the pipe. At the same time, the buffer rib 15 can be made of deformable material, which can effectively reduce the impact on the front of the pipe. Moreover, the buffer layer 12 itself has deformability and wraps around the pipe body 13, which can effectively protect the pipe.

[0032] 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.
