Technical Field

[0001] The utility model relates to the technical field of assembly structures, and particularly relates to an assembly structure of a dam protection net for water conservancy projects. Background Technique

[0002] The dam protection net for water conservancy projects is a protection structure used to protect dams from erosion, scouring and impact by external objects. This protection net is usually made of high-strength materials such as steel wire ropes, polyester fibers (PES) or polypropylene fibers (PP), etc., and has good weather resistance and tensile strength. At the same time, during floods, the protection net can intercept floating objects and sundries to avoid damage to the dam.

[0003] Most of the existing dam protection nets are fixed to fixed piles by multiple groups of bolts to complete the assembly work of the protection net, which is time-consuming and laborious, increases the workload of operators, and at the same time reduces the subsequent disassembly and replacement efficiency of the protection net. Therefore, an assembly structure of a dam protection net for water conservancy projects needs to be proposed. Content of the Utility Model

[0008] Preferably, a bearing is fixedly connected to the inside of the connecting plate, and the connecting plate is movably connected to the threaded rod through the bearing.

[0009] Preferably, the locking block penetrates through the inside of the insertion block and extends into the inside of the fixing pile, and the locking block is movably connected to the insertion block and the fixing pile.

[0010] Preferably, the protection mechanism includes a bolt, a connecting rod, a protection plate and a diversion hole. A bolt is movably connected inside the reinforcing frame. One end of the bolt is fixedly connected to a connecting rod. A protection plate is movably connected to the outer wall of the connecting rod.

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

[0013] 1. For this assembly structure of a dam protection net for water conservancy projects, through the coordinated use of the loading and unloading mechanism, during the use of the device, by inserting the insertion blocks on both sides of the reinforcing frame into the fixing piles, then pulling the pull handle upwards, through the connection of the movable rod, the height of the limiting block and the insertion rod is lifted. Then, by rotating the rotating handle, the rotation of the threaded rod is driven. Subsequently, through the mutual meshing of the threaded rod and the first right-angle plate, the position of the connecting plate is driven to move. At the same time, the locking block is driven to insert into the fixing pile and penetrate through the insertion block. Then, by releasing the pull handle, the elastic force of the spring is restored, driving the height of the limiting block and the insertion rod to drop. Subsequently, the insertion rod is driven to insert into the inside of the rotating handle to lock the state of the threaded rod, effectively improving the stability of the protection net assembly, saving time and effort, reducing the workload of the operator, and improving the assembly efficiency of the protection net, facilitating subsequent disassembly or replacement.

At the same time, when the water flow impacts the protection net body, the water flow first passes through the diversion holes on the protection plate, enters through the small-diameter orifice of the diversion hole, and exits through the large-diameter orifice, reducing the speed of the water flow and at the same time reducing the impact force of the water flow on the protection net body, effectively improving the protection effect on the protection net body.

The insertion block 501 is movably connected inside the fixed pile 1. One side of the fixed pile 1 is fixedly connected with the first right-angle plate 502. The threaded rod 503 is movably connected inside the first right-angle plate 502. One end of the threaded rod 503 is movably connected with the connecting plate 504. A bearing is fixedly connected inside the connecting plate 504. The connecting plate 504 is movably connected with the threaded rod 503 through the bearing, preventing the connecting plate 504 from rotating with the rotation of the threaded rod 503 and improving the stability of the connecting plate 504. One side of the connecting plate 504 is fixedly connected with the locking block 505. The locking block 505 penetrates inside the insertion block 501 and extends into the inside of the fixed pile 1. The locking block 505 is movably connected with the insertion block 501 and the fixed pile 1, improving the connection stability between the insertion block 501 and the fixed pile 1, and at the same time improving the installation stability of the reinforcement frame 3 and the protection net body 4 with the fixed pile 1.

[0024] Working principle: When using the assembly structure of the dam protection net for water conservancy projects, first insert the insertion blocks 501 on both sides of the reinforcement frame 3 into the fixed piles 1 on both sides respectively. Then pull the handle 512 upwards. Through the connection of the movable rod 509, drive the lifting of the height of the limit block 508 and the insertion rod 507, and then drive the extrusion of the spring 510 by the limit block 508.

Then align the bolt 601 with the corresponding position of the reinforcement frame 3 and turn the connecting rod 602 to drive the engagement of the bolt 601 and the reinforcement frame 3, achieving the installation work of the protection plate 603 and the reinforcement frame 3. When the water flow impacts the protection net body 4, the water flow first passes through the diversion holes 604 on the protection plate 603, enters through the small-diameter openings of the diversion holes 604, and exits through the large-diameter openings, reducing the speed of the water flow and at the same time reducing the impact force of the water flow on the protection net body 4. Just like this, the use process of the assembly structure of the dam protection net for water conservancy projects is completed.
