Description

Technical Field

[0001] This utility model relates to the field of water conservancy and hydropower construction technology, specifically a protective device for water conservancy and hydropower construction. Background Technology

[0002] Water conservancy projects are generally built in mountainous or valley areas with rugged terrain, which are prone to geological disasters such as landslides and mudslides. The stability of the slopes directly affects the overall quality of the project, so the application of slope protection technology is particularly important.

[0003] Application No. 202322962977.9 discloses a slope protection device for water conservancy and hydropower construction. The device allows for quick disassembly and replacement of the replacement box, making it easy to operate. During use, simply moving two pull plates towards the center is sufficient to complete the disassembly and assembly of the replacement box, facilitating replacement and maintenance without having to remove the entire protective frame, thus avoiding disruption to the surrounding protective frames in normal use.

[0004] The size and structure of the protective frame in the above application are fixed, but the surface of the slope is uneven, making it difficult to fit the protective frame. At the same time, a large number of protective frames are required, resulting in high costs. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a protective device for water conservancy and hydropower construction, which solves the problems mentioned in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a protective device for water conservancy and hydropower construction, comprising an installation box, an internal storage groove, a rotatably connected roller inside the storage groove, a protective net wrapped around the outer side of the roller, an inlet / outlet inside the installation box on one side of the storage groove, one end of the protective net passing through the inlet / outlet and fixedly connected to a protective strip, first mounting components installed on corresponding sides of the installation box, and second mounting components installed on corresponding sides of the protective strip, both the first and second mounting components having mounting holes inside, the protective strip having an L-shaped structure, and multiple protruding spikes fixedly connected to one side of the protective net.

[0007] Preferably, a guide roller is installed inside the storage groove and on one side of the protective net.

[0008] Preferably, one end of the spool is provided with a spring.

[0009] Preferably, the mounting box has multiple positioning holes inside and on one side of the storage slot and inlet / outlet. A pressure plate is slidably connected inside the storage slot and on one side of the roll. Multiple positioning spikes are installed on one side of the pressure plate. The multiple positioning spikes pass through the protective net and are inserted into the multiple positioning holes.

[0010] Preferably, a threaded post is threadedly connected to one side of the mounting box, and one end of the threaded post is rotatably connected to the pressure plate.

[0011] Preferably, the protective net is a steel wire rope net.

[0012] This utility model provides a protective device for water conservancy and hydropower construction, which has the following beneficial effects:

[0013] 1. This protective device for water conservancy and hydropower construction uses a protective net installed between the installation box and the L-shaped protective strip. With the rotation of the roller inside the installation box, the protective net can be unfolded to the required length according to the slope area, fitting the slope perfectly. It does not require a large number of nets and has a low cost. At the same time, the multiple protruding spikes on the protective net help increase friction with the slope, making the protective net more stable. Furthermore, the L-shaped structure of the protective strip can further intercept falling debris and other materials.

[0014] 2. This protective device for water conservancy and hydropower construction uses a spring at one end of the reel to automatically rotate the reel and rewind the unfolded protective netting. This improves efficiency and reduces manpower consumption. Furthermore, the pressure plate inside the installation box pushes multiple positioning spikes to move under the action of the threaded column, which facilitates secondary fixation of the unfolded protective netting and avoids instability caused by the tension of the protective netting due to the spring.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a protective device for water conservancy and hydropower construction, including an installation box 1. The installation box 1 has a storage groove 2 inside, and a roller 3 is rotatably connected inside the storage groove 2. A protective net 5 is wound around the outside of the roller 3. An inlet / outlet 4 is located inside the installation box 1 and on one side of the storage groove 2. One end of the protective net 5 passes through the inlet / outlet 4 and is fixedly connected to a protective strip 6. The stretching of the protective strip 6 causes the protective net 5 to drive the roller 3 to rotate, thus unfolding the protective net 5 to a corresponding length, covering the slope surface for slope protection. The protective net 5 is a steel wire rope net, possessing high strength and flexibility, adaptable to various terrains and effectively protecting slopes. A spring is provided at one end of the roller 3 to provide force for the rotation of the roller 3 and the automatic winding of the protective net 5. First mounting parts 7 are installed on corresponding sides of the installation box 1, and second mounting parts 8 are installed on corresponding sides of the protective strip 6. Both the first mounting parts 7 and the second mounting parts 8 have mounting holes 9 inside, facilitating the installation of the installation box 1 and the protective strip 6. The protective strips 6 are L-shaped and fixed to the slope to intercept falling rocks and other materials. Multiple protruding spikes 10 are fixedly connected to one side of the protective netting 5 to increase friction with the slope surface and make the netting 5 more stable. A guide roller 11 is installed inside the receiving groove 2 on one side of the protective netting 5 to limit its movement and prevent wear with the mounting box 1. Multiple positioning holes 12 are opened inside the mounting box 1 on one side of the receiving groove 2 and the inlet / outlet 4. A pressure plate 13 is slidably connected inside the receiving groove 2 on one side of the roller 3. Multiple positioning spikes 14 are installed on one side of the pressure plate 13, passing through the protective netting 5 and inserting into the positioning holes 12. A threaded post 15 is threaded to one side of the mounting box 1. One end of the threaded post 15 is rotatably connected to the pressure plate 13, causing the pressure plate 13 to shift as the threaded post 15 rotates. The multiple positioning spikes 14 on the pressure plate 13 are then inserted into the positioning holes 12, passing through the protective netting 5 for secondary fixing.

[0022] In summary, when using this protective device for water conservancy and hydropower construction, the installation box 1 is fixed to the slope by nails and the first mounting parts 7 on both sides of the installation box 1. Then, the protective strip 6 is pulled. Through the connection between the protective strip 6 and one end of the protective net 5 wrapped around the outside of the inner roller 3 of the installation box 1, the roller 3 is rotated, causing the protective net 5 to unfold to the corresponding length and cover the slope. After the protective strip 6 is fixed to the slope by the second mounting part 8, the protective net 5 is pressed down, causing multiple protruding spikes 10 on the protective net 5 to pierce into the slope. At this time, the threaded post 15 connected to the threaded connection on the installation box 1 is rotated, pushing the pressure plate 13 inside the installation box 1 to move. This causes multiple positioning spikes 14 on one side of the pressure plate 13 to pass through the protective net 5 and insert into multiple positioning holes 12 in the storage groove 2, thus fixing the protective net 5 a second time. The protective net 5 and the L-shaped protective strip 6 intercept falling rocks and other materials on the slope. Similarly, as needed, the operation can be repeated to increase the position of the installation box 1 and the protective strip 6 and expand the protection range of the protective net 5.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
