Description

Technical Field

[0001] This utility model relates to the field of ecological slope protection technology, and in particular to an ecological slope protection device for water conservancy projects. Background Technology

[0002] With increasing awareness of ecological protection, ecological slope protection technology, as a key means of maintaining ecological balance and preventing soil erosion, is undergoing rapid development and transformation. Ecological slope protection nets have emerged in response to this need. Ecological slope protection nets are usually made of high-strength, corrosion-resistant materials, with good flexibility and permeability. They can effectively adapt to different terrains and water flow conditions. Their unique grid structure not only helps plant roots grow and extend, forming a stable vegetation root network and enhancing the soil's resistance to erosion, but also provides habitat for microorganisms and small animals, promoting the diversity and stability of the ecosystem.

[0003] For example, in the prior art, there is a slope protection net for water conservancy projects that is easy to replace, publication number: CN218990064U. This solution allows for convenient and quick disassembly and replacement of the slope protection net frame and the main body of the slope protection net as a whole. It avoids the disadvantage that the existing slope protection nets and water conservancy slopes used in water conservancy projects are inconvenient to disassemble and replace after installation. This makes disassembly and replacement very time-saving and labor-saving, greatly improving the efficiency of replacement. Moreover, it is simple to operate and easy for people to replace and use.

[0004] However, when the slope protection net is not severely damaged, that is, when there is only a small area of ​​damage, it is not convenient to replace or remove the small area of ​​slope protection net in that area. The slope protection net of the above-mentioned patent is a whole piece of slope protection net. If it is to be removed and replaced, the whole piece needs to be replaced, which is costly and labor-intensive. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art and to propose an ecological slope protection device for water conservancy projects.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an ecological slope protection device for water conservancy projects, comprising a slope protection net body and a fixing mechanism for fixing the slope protection net body. The fixing mechanism includes an installation circular plate, a rotating column rotatably connected to the center of the upper surface of the installation circular plate, the two ends of the rotating column penetrating the installation circular plate and extending outward, a brake bevel gear fixedly connected to the outer surface of the rotating column and above the installation circular plate, four installation blocks arranged in a circumferential array in the edge and center areas of the upper surface of the installation circular plate, threaded rods rotatably connected between each corresponding installation block, a driven bevel gear meshing with the brake bevel gear fixedly connected to the end face of each threaded rod near the brake bevel gear, a sliding groove arranged along the axial direction of the threaded rod is opened on the upper surface of the installation circular plate and below each threaded rod, a sliding block slidably connected in each sliding groove, each sliding block being threadedly connected to the corresponding threaded rod, and a grab hook arranged along the axial direction of the threaded rod fixedly connected to each installation block.

[0007] Preferably, the slope protection net body includes a slope protection net and a fixing frame, and each corner of the fixing frame is fixedly connected with a fixing ring.

[0008] Preferably, a mounting cover is also fixedly connected to the mounting disc. A fixed circular plate through which one end of the rotating column passes is fixedly connected to the upper end face of the mounting cover. Several fixing holes are arranged in a circumferential array on the edge area of ​​the fixed circular plate. A connecting block is fixedly connected to the end face of the rotating column that passes through the fixed circular plate and extends outward. A connecting port with the same diameter as the fixing hole is opened at the end of the connecting block. A fixing column is provided in the connecting port.

[0009] Preferably, the length of the connecting block is equal to the radius of the upper surface of the fixed circular plate.

[0010] A hexagonal block coaxially arranged with the rotating column is fixedly connected to the connecting block.

[0011] Preferably, the bottom of the mounting circular plate is fixedly connected with a plurality of sealing covers in a circumferential array. The bottom of the mounting circular plate and each sealing cover is provided with a mounting hole. A sliding rod is slidably connected in each mounting hole. One end of the sliding rod passes through the sealing cover and extends downward. A pressing block is fixedly connected to the outer surface of the sliding rod and inside the sealing cover. A spring is provided between the pressing block and the mounting circular plate and sleeved on the outer surface of the sliding rod. Limit blocks are fixedly connected to both the upper and lower end faces of the sliding rod.

[0012] Preferably, the bottom of the mounting plate is also provided with several drainage holes.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, regarding fixing and assembly, the brake bevel gear and the driven bevel gear mesh precisely. The rotation of the brake bevel gear drives the driven bevel gear to rotate, and the driven bevel gear drives the corresponding threaded rod to rotate. Each sliding block, combined with the limiting effect of the sliding groove, drives the upper grab hook to move outward, thereby enabling the grab hook to extend and retract precisely. This achieves the fixing of the slope protection net. Furthermore, multiple fixing mechanisms can combine small-area slope protection nets into large-area slope protection nets to meet the slope protection needs of different ranges. At the same time, when the slope protection net is partially damaged, only the corresponding small area of ​​the slope protection net needs to be replaced, without the need for overall replacement, which greatly improves maintenance efficiency and reduces replacement costs.

[0014] 2. In this utility model, the hexagonal block design facilitates the use of special tools to drive the rotating column, making the operation more labor-saving and efficient. The design of the connecting block allows for manual tightening even without special tools, improving the applicability of the device in different scenarios. The cooperation between the fixed column, the fixed hole, and the connecting port can prevent the rotating column from rotating accidentally, ensuring the stability of the slope protection net and preventing loosening.

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] like Figure 1-5 As shown, an ecological slope protection device for water conservancy projects includes a slope protection net body and a fixing mechanism for fixing the slope protection net body. The fixing mechanism includes an installation circular plate 1. A rotating column 2 is rotatably connected to the center of the upper surface of the installation circular plate 1. The two ends of the rotating column 2 pass through the installation circular plate 1 and extend outward. A brake bevel gear 3 is fixedly connected to the outer surface of the rotating column 2 and above the installation circular plate 1. Four installation blocks 4 are arranged in a circular array in the edge area and the center area of ​​the upper surface of the installation circular plate 1. Threaded rods 5 are rotatably connected between each corresponding installation block 4. A driven bevel gear 6 that meshes with the brake bevel gear 3 is fixedly connected to the end face of each threaded rod 5 near the brake bevel gear 3. A sliding groove 7 is opened on the upper surface of the installation circular plate 1 and below each threaded rod 5, and a sliding block 8 is slidably connected in each sliding groove 7. Each sliding block 8 is threadedly connected to the corresponding threaded rod 5. A grab hook 9 is fixedly connected to each installation block 4 along the axial direction of the threaded rod 5. The main body of the slope protection net includes a slope protection net 10 and a fixed frame 11, with fixed rings 12 fixedly connected to each corner of the fixed frame 11.

[0021] The specific working process of this scheme is as follows: When the slope protection net 10 needs to be installed, the workers use a special tool to drive the rotating column 2 to rotate. The rotating column 2 will drive the brake bevel gear 3 on its outer surface to rotate together. Since the brake bevel gear 3 meshes with the four driven bevel gears 6, under the drive of the brake bevel gear 3, the four driven bevel gears 6 respectively drive the threaded rods 5 between the corresponding mounting blocks 4 to rotate. When the threaded rod 5 rotates, because the sliding block 8 is threadedly connected to the threaded rod 5, and the sliding block 8 is restricted in the sliding groove 7 to move only along the axial direction of the threaded rod 5, Each sliding block 8 moves outward along the corresponding threaded rod 5, and the hooks 9 on the sliding block 8 also move and are eventually exposed outside the device. At this time, the workers put the fixing rings 12 at the corners of the fixing frame 11 in the main body of the slope protection net 10 onto the corresponding hooks 9. After the installation is completed, the rotating column 2 is driven to rotate in the opposite direction. The rotating column 2 drives the threaded rod 5 to rotate in the opposite direction through the meshing of the brake bevel gear 3 and the driven bevel gear 6, so that the sliding block 8 drives the hooks 9 to retract inward. The hooks 9 tighten the fixing rings 12, thereby fixing the main body of the slope protection net. When it is necessary to combine a large area of ​​slope protection net 10, multiple such fixing mechanisms can be used to fix each small area of ​​slope protection net body separately, and then splice them into a large area of ​​slope protection net 10. If the slope protection net body of a small area is damaged, follow the reverse steps above, drive the rotating column 2 to move the hook 9 outward, and remove the fixing ring 12 of the damaged slope protection net body from the hook 9 for replacement.

[0022] like Figure 2 As shown, a mounting cover 13 is also fixedly connected to the mounting disc. A fixed circular plate 14, through which one end of the rotating column 2 passes, is fixedly connected to the upper end face of the mounting cover 13. Several fixing holes 26 are arranged in a circular array on the edge area of ​​the fixed circular plate 14. A connecting block 15 is fixedly connected to the end face of the rotating column 2 that passes through the fixed circular plate 14 and extends outward. A connecting port 16 with the same diameter as the fixing hole 26 is opened at the end of the connecting block 15. A fixing column 17 is provided in the connecting port 16. The length of the connecting block 15 is equal to the radius of the upper surface of the fixed circular plate 14; A hexagonal block 18, coaxially arranged with the rotating column 2, is fixedly connected to the connecting block 15.

[0023] Further explanation of this solution: The installation cover 13 and the installation circular plate 1 can further reduce the entry of external dust and soil into the device. After the fixing operation of the hook 9 to the slope protection net 10 is completed by the rotating column 2, the operator can rotate the connecting block 15 slightly so that the connecting port 16 on the connecting block 15 is aligned with a certain fixing hole 26 on the fixing circular plate 14. Then, the fixing column 17 is inserted into the connecting port 16 and the corresponding fixing hole 26. At the same time, since the length of the connecting block 15 is equal to the radius of the upper surface of the fixing circular plate 14, it can be ensured that the connecting port 16 has a sufficient range of rotation to align with different fixing holes 26. Through the fixing action of the fixing column 17, it can effectively prevent the rotating column 2 from rotating unexpectedly in the non-operational state, ensuring the stability of the fixing state of the hook 9 to the slope protection net 10 and preventing the slope protection net 10 from loosening. The hexagonal block 18 is designed to make it easier for workers to use special tools to engage with the hexagonal block 18 and drive the rotating column 2 to rotate, making the rotation operation of the rotating column 2 more convenient and labor-saving, and improving the work efficiency when installing and dismantling the slope protection net 10. Meanwhile, when staff do not have special tools, they can manually turn the connecting block 15, which in turn drives the rotating column to rotate. This allows the hook 9 to extend and retract even with a slightly reduced operating speed, further improving the portability and practicality of the device.

[0024] like Figure 5As shown, a number of sealing covers 19 are fixedly connected in a circumferential array at the bottom of the mounting plate 1. Mounting holes 20 are provided at the bottom of the mounting plate 1 and in each sealing cover 19. A sliding rod 21 is slidably connected in each mounting hole 20. One end of the sliding rod 21 passes through the sealing cover 19 and extends downward. A pressing block 22 is fixedly connected to the outer surface of the sliding rod 21 and inside the sealing cover 19. A spring 23 is provided between the pressing block 22 and the mounting plate 1 and sleeved on the outer surface of the sliding rod 21. Limiting blocks 24 are fixedly connected to both the upper and lower ends of the sliding rod 21.

[0025] The purpose of this solution is that the elasticity of the spring 23 allows the sliding rod 21 to always fit tightly against the slope surface. Even if there is some unevenness on the slope surface, it can be adjusted by the extension and retraction of the sliding rod 21 to ensure the stable installation of the mounting plate 1. At the same time, the sealing cover 19 can protect the internal spring 23 and the compression block 22, preventing external soil, water and other substances from entering and affecting their normal operation, thus extending the service life of the components.

[0026] like Figure 3 As shown, the bottom of the mounting plate 1 is also provided with several drainage holes 25.

[0027] The purpose of this solution is to ensure that when rainwater or other water accumulates at the bottom of the mounting plate 1, the water will be discharged in time through the drainage hole 25, thus avoiding the water from lingering at the bottom of the mounting plate 1 for a long time and reducing the water's immersion and corrosion on the mounting plate 1 and related bottom components.

[0028] Meanwhile, after fixing each small area of ​​the slope protection net body separately and splicing them into a large area slope protection net 10, the overall fixing of the slope protection net 10 can be completed by driving fixing piles into the fixed slope surface and then putting the fixing rings 12 at the four corners of the large area slope protection net 10 onto the corresponding fixing piles.

[0029] In addition, the threaded rod 5, the brake bevel gear 3, and the driven bevel gear 6 in this design are all made of stainless steel. Furthermore, the special tool mentioned in this solution for driving the rotating column 2 to rotate is a tool that already exists in the prior art. You can refer to the electric hex wrench in the prior art. When using it, simply align the electric hex wrench with the hexagonal block 18 in this solution and complete the engagement between the two. After that, powering on the electric hex wrench will drive the rotating column 2 to rotate, further promoting the progress of this solution.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
