Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a protective net for water conservancy projects. Background Technology

[0002] Water conservancy projects are mostly built in mountainous areas and along rivers. These areas have complex geological conditions and poor slope stability, making them prone to geological disasters such as landslides, collapses, and debris flows. Taking some water conservancy projects in Southwest China as an example, because they are located in earthquake-prone zones with fractured rocks, they face significant slope safety risks during construction and operation. Protective nets are of great significance in these projects, as they can reinforce and protect slopes and effectively reduce the occurrence of disasters. However, some existing protective nets have shortcomings. On the one hand, some protective nets are rigid structures with poor flexibility and high requirements for slope flatness. When encountering rugged terrain or terrain with large slope changes, installation is difficult and it is hard to fit tightly to the slope surface, resulting in protective gaps. On the other hand, the protective performance is lacking. The mesh size of some protective nets is not designed reasonably, and they cannot effectively intercept small pieces of gravel or debris, allowing some objects to pass through the mesh and cause harm. Utility Model Content

[0003] The main purpose of this utility model is to provide a protective net for water conservancy projects, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A protective net for water conservancy projects includes a slope protection frame. The inner front wall, inner rear wall, inner upper arm, and inner lower wall of the slope protection frame are all fixedly connected to a wire rope net body. The left end of the slope protection frame is threadedly connected to four rivet studs. The outer surface of each of the four rivet studs is fixedly connected to a stop block. The four stop blocks are located on the left side of the slope protection frame. The left front and left rear of the slope protection frame are fixedly connected to three threaded fixing rods. The outer surface of the six threaded fixing rods is threadedly connected from right to left to an inner protective structure, a middle protective structure, and an outer protective structure. The outer surface of each of the six threaded fixing rods is threadedly connected to a reinforcing nut.

[0006] Preferably, the inner protective structure includes a wire mesh body, and three reinforcing ear plates are fixedly connected to the front and rear ends of the wire mesh body. Each of the six reinforcing ear plates has a threaded hole that passes through from left to right at the middle of its right end.

[0007] By adopting the above technical solution: the rivet ground nails and blocks fix the slope protection frame to enhance stability; the threaded fixing rods connect the inner, middle and outer protective structures and are locked by reinforcing nuts; in the inner protective structure, the steel wire mesh is equipped with reinforcing ear plates and threaded holes to enhance interception and protection and improve the overall protection effect.

[0008] Preferably, the wire mesh body is located directly to the left of the wire rope mesh body, and the six threaded holes correspond to the positions of the six threaded fixing rods respectively. The area of ​​the wire mesh body is larger than the area of ​​the wire rope mesh body, and the wire mesh body is threadedly connected to the six threaded fixing rods through six reinforcing ear plates.

[0009] By adopting the above technical solution, the area of ​​the steel wire mesh is larger than that of the steel wire rope mesh, and it is located to the left of the steel wire rope mesh, which can provide more comprehensive protection. The inner protective structure is installed firmly by connecting the threaded holes on the reinforcing ear plate with the threaded fixing rod. It works in conjunction with the steel wire rope mesh to enhance the protection of the slope of the water conservancy project and reduce the passage of debris.

[0010] Preferably, the middle protective structure includes a steel rope perforated mesh body, and three reinforcing ear plates are fixedly connected to the front and rear ends of the steel rope perforated mesh body. Each of the six reinforcing ear plates has a threaded hole that passes through to the left and right at the middle of its right end.

[0011] By adopting the above technical solution: the steel rope mesh with holes in the middle can be stably installed in the designated position by means of the reinforcing ear plates at the front and rear ends, and the threaded holes on the ear plates are connected to the threaded fixing rods. The steel rope material and the design of the holes can effectively buffer and intercept impacts of a certain size, thereby enhancing the overall protective performance of the protective net.

[0012] Preferably, the area of ​​the steel rope perforated mesh body is the same as the area of ​​the steel wire mesh body. The steel rope perforated mesh body is located to the left of the steel wire mesh body. The six threaded holes correspond to the positions of the six threaded fixing rods. The steel rope perforated mesh body is threadedly connected to the six threaded fixing rods through six reinforcing ear plates.

[0013] By adopting the above technical solution: the steel rope mesh and the steel wire mesh have the same area and are arranged in sequence. They are connected to the threaded fixing rod through the reinforcing ear plate and threaded hole, and are firmly installed in the middle layer of the protective net. Its structure can buffer and disperse the impact force. In conjunction with the inner steel wire mesh, it can provide graded protection against debris of different sizes and impact forces, thereby improving the overall protection effect.

[0014] Preferably, the outer protective structure includes a fine reinforced protective net, and three reinforcing ear plates are fixedly connected to the front and rear ends of the fine reinforced protective net. Each of the six reinforcing ear plates has a threaded hole that passes through from left to right at the middle of its right end.

[0015] By adopting the above technical solution: the fine reinforced protective net is connected to the threaded fixing rod through the reinforced ear plates at the front and rear ends and the threaded holes on the top, so as to achieve a stable installation. Its fine structure can effectively block small debris. As the outermost line of defense, it works in conjunction with the internal structure to enhance the overall comprehensiveness and tightness of the protective net.

[0016] Preferably, the area of ​​the fine reinforcing protective net is the same as the area of ​​the perforated mesh of the steel rope. The fine reinforcing protective net is located to the left of the perforated mesh of the steel rope. The six threaded holes correspond to the positions of the six threaded fixing rods. The fine reinforcing protective net is threadedly connected to the six threaded fixing rods through the six reinforcing ear plates. The six reinforcing ear plates are located to the right of the six reinforcing nuts.

[0017] By adopting the above technical solution: the fine reinforced protective net and the steel rope have the same area of ​​perforated mesh and are arranged in sequence. They are connected to the threaded fixing rod through reinforced ear plates and threaded holes to ensure stable installation. It is located on the outermost layer. Its fine structure can intercept small particles. The reinforced ear plates and reinforced nuts cooperate to further tighten it, thereby enhancing the overall ability of the protective net to block external debris and improving the protective effect.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In this utility model, the steel wire rope net is fixed by the slope protection frame, which enhances the stability of the overall structure. The rivet nails and blocks work together to firmly install the protective net on the slope and prevent it from shifting. The threaded fixing rods provide connection support for each layer of the protective structure, which is convenient for installation and disassembly and maintenance. The inner, middle and outer protective structures work together to form a multi-layered protection system, which can intercept stones and debris of different sizes in different grades, effectively improving the protection performance. The reinforcing nuts further tighten each layer of the protective structure to ensure that they are tightly connected, so that the protective net can play a stable role in the complex water conservancy environment and reduce the impact of water conservancy projects on disasters such as soil erosion and landslides.

[0020] 2. In this utility model, the multi-layered protective structure is progressively enhanced. The steel wire mesh first intercepts larger stones, the steel rope mesh further blocks medium-sized objects, and the fine reinforced protective net intercepts small pieces of gravel and debris, achieving graded protection and greatly improving interception efficiency and protective performance. Each layer of the protective structure is connected to the threaded fixing rod through reinforced ear plates and threaded holes, making installation convenient and stable, as well as easy to disassemble and maintain. The protective net area is progressively larger and can expand the protection range, effectively reducing protection loopholes. Overall, it can provide reliable protection for water conservancy projects, resist various impacts and damage, and ensure the stability and safety of the project. Attached Figure Description

[0030] Please see Figure 1-4 This utility model provides a technical solution:

[0031] A protective net for water conservancy projects includes a slope protection frame 1. The inner front wall, inner rear wall, inner upper arm, and inner lower wall of the slope protection frame 1 are all fixedly connected to a wire rope net body 2. The left end of the slope protection frame 1 is threadedly connected to four circumferences of rivet nails 3. The outer surface of each of the four rivet nails 3 is fixedly connected to a stop block 4. The four stop blocks 4 are located on the left side of the slope protection frame 1. The front and rear left ends of the slope protection frame 1 are fixedly connected to three threaded fixing rods 5. The outer surfaces of the six threaded fixing rods 5 are threadedly connected from right to left to an inner protective structure 6, a middle protective structure 7, and an outer protective structure 8. The outer surfaces of the six threaded fixing rods 5 are threadedly connected to a reinforcing nut 9.

[0032] In this embodiment, the inner protective structure 6 includes a wire mesh 61. Three reinforcing ear plates 62 are fixedly connected to both the front and rear ends of the wire mesh 61. Each of the six reinforcing ear plates 62 has a threaded hole 63 passing through its right end. The wire mesh 61 is located directly to the left of the wire rope mesh 2. The six threaded holes 63 correspond to the positions of the six threaded fixing rods 5. The area of ​​the wire mesh 61 is larger than the area of ​​the wire rope mesh 2. The wire mesh 61 is threadedly connected to the six threaded fixing rods 5 via the six reinforcing ear plates 62. The middle protective structure 7 includes a steel rope perforated mesh 71. Three reinforcing ear plates 72 are fixedly connected to both the front and rear ends of the steel rope perforated mesh 71. Each of the six reinforcing ear plates 72 has a threaded hole 73 passing through its right end. The area of ​​the steel rope perforated mesh 71 is the same as the area of ​​the wire mesh 61. The perforated mesh body 71 is located directly to the left of the wire mesh body 61. The six threaded holes 73 correspond to the positions of the six threaded fixing rods 5. The perforated mesh body 71 of the steel rope is threadedly connected to the six threaded fixing rods 5 through the six reinforcing ear plates 72. The outer protective structure 8 includes a fine reinforced protective net 81. The front and rear ends of the fine reinforced protective net 81 are fixedly connected with three reinforcing ear plates 82. The right end of each of the six reinforcing ear plates 82 has a threaded hole 83 that passes through from left to right. The area of ​​the fine reinforced protective net 81 is the same as the area of ​​the perforated mesh body 71 of the steel rope. The fine reinforced protective net 81 is located directly to the left of the perforated mesh body 71 of the steel rope. The six threaded holes 83 correspond to the positions of the six threaded fixing rods 5. The fine reinforced protective net 81 is threadedly connected to the six threaded fixing rods 5 through the six reinforcing ear plates 82. The six reinforcing ear plates 82 are located directly to the right of the six reinforcing nuts 9.

[0033] Through the above scheme: the wire rope mesh 2 is fixed inside the slope protection frame 1. It has a certain degree of flexibility. The rivet nails 3 and the stop blocks 4 cooperate to fix the slope protection frame 1 to the slope surface. Even if the slope surface is rugged or the slope changes greatly, it can be installed relatively stably. At the same time, the wire mesh 61, the steel rope perforated mesh 71 and the fine reinforced protective net 81 are connected to the threaded fixing rod 5 by the reinforcing ear plate 1 62, reinforcing ear plate 2 72, reinforcing ear plate 3 82 and the corresponding screw holes. This connection method allows each layer of protective structure to have a certain amount of room for movement, which can better adapt to the shape of the slope and reduce protective gaps. Therefore, from the inner layer to the outer layer, the mesh size of the protective net gradually decreases. The wire mesh 61 can initially intercept larger stones, the steel rope perforated mesh 71 can further intercept medium-sized gravel, and the fine reinforced protective net 81 can effectively intercept small gravel and debris. Through this graded interception, the overall protective performance is improved.

[0034] It should be noted that this utility model is a protective net for water conservancy projects. During use, firstly, the wire rope net body 2 is fixed inside the slope protection frame 1. Then, by using rivets 3 and stoppers 4, the slope protection frame 1 is securely installed on the slope of the water conservancy project, thus fixing the foundation of the entire protective net. The threaded fixing rods 5 on the slope protection frame 1 provide connection support for each protective layer. The inner layer of wire mesh 61 is threadedly connected to the threaded fixing rods 5 through threaded holes 63 on the reinforcing ear plate 62. The middle layer of steel rope perforated mesh 71 is connected to the reinforcing ear plate 72 and threaded holes 63. Similarly, 73 is connected to the threaded fixing rod 5. The outer layer of fine reinforced protective netting 81 is also connected to the threaded fixing rod 5 via the reinforcing ear plate 82 and the threaded hole 83. Finally, it is locked with the reinforcing nut 9 to ensure that the protective structures of each layer are tightly combined. Therefore, when stones or debris impact the protective netting, the wire mesh 61 first intercepts larger objects, the steel rope perforated mesh 71 further blocks medium-sized objects, and the fine reinforced protective netting 81 intercepts small pieces of gravel and debris, thus achieving graded protection. In this way, the overall structure works together to effectively solve the problems of poor terrain adaptability and insufficient protective performance of existing protective netting.
