[0013] 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.
[0014] Example: See Figures 1 to 4 This utility model discloses a ditch cover structure with an anti-fall net, comprising a first cover plate 1, and a second cover plate 2 on one side of the first cover plate 1. The combined design of the first cover plate 1 and the second cover plate 2 facilitates individual transportation and installation, reduces handling difficulty, and allows for easy replacement in case of partial damage, significantly reducing maintenance costs and improving the overall practicality of the structure. Both the first cover plate 1 and the second cover plate 2 have anti-slip mechanisms at their tops and anti-fall mechanisms at their bottoms. The arrangement of the first cover plate 1 and the second cover plate 2 enables the function of covering the ditch. The anti-slip mechanism includes protrusions 3 located on the sides of the first cover plate 1 and the second cover plate 2. Both the first cover plate 1 and the second cover plate 2 have anti-slip strips 4 on their tops. The top of the protrusions 3 has multiple threaded holes, in which screws are threadedly connected. The bolt 9, an anti-slip mechanism, through the cooperation of the protrusion 3, anti-slip strip 4 and bolt 9, not only significantly increases the friction of the cover plate surface, effectively preventing pedestrians from slipping when wet or walking, and improving walking safety, but also ensures that the anti-slip structure is stable and reliable, and is not easy to loosen or fail due to long-term use; the surface of the first cover plate 1 and the second cover plate 2 is provided with drainage grooves 5, and each drainage groove 5 is equipped with a water filter plate 14 with honeycomb holes. The design of the drainage groove 5 facilitates the rapid drainage of water accumulated on the surface of the cover plate, preventing rainwater or other sewage from accumulating on the cover plate, keeping the cover plate surface dry, and thus reducing the risk of pedestrians slipping; and the setting of the water filter plate 14 prevents pedestrians' heels from getting stuck in the drainage groove 5 when passing over the cover plate (especially high heels). The side ends of the first cover plate 1 and the second cover plate 2 are provided with limit holes 6.
[0015] In this utility model, a limiting post 7 is fixedly connected to the second cover plate 2 inside the limiting hole 6, and the outer edge of the limiting post 7 is set as a beveled surface for insertion into the limiting hole 6; the matching structure of the limiting hole 6 and the limiting post 7 can accurately realize the positioning connection of the first cover plate 1 and the second cover plate 2, effectively preventing the two cover plates from being misaligned or shifted when subjected to external force, ensuring the stability of the overall structure of the cover plates, and avoiding safety hazards caused by gaps due to misalignment of the cover plates; the anti-fall mechanism includes an anti-fall net 8 located at the bottom of the first cover plate 1 and the second cover plate 2, and the edge of the anti-fall net 8 is provided with a net buckle 10. The net buckle 10 adopts a flexible circular ring structure. When installed, the net buckle 10 will become elliptical due to the tensile force, preventing the connecting end of the net buckle 10 from falling off; thus, the setting of the net buckle 10 facilitates the hanging operation of the anti-fall net 8; multiple horizontally arranged positioning posts are fixedly connected to the inner walls of the bottom of the first cover plate 1 and the second cover plate 2. 12, and the outer end of the positioning post 12 is suspended and fixed with an anti-detachment block. The top of the positioning post 12 is slidably sleeved with a snap-fit block 11 for hooking the mesh buckle 10. The snap-fit block 11 has an L-shaped block structure. A spring 13 is sleeved on the positioning post 12. The spring 13 is located on the positioning post 12 inside the snap-fit block 11, and the sliding sleeve end of the snap-fit block 11 is located on the positioning post 12 between the anti-detachment block and the spring 13. With the setting of the anti-fall net 8, it is easy to effectively prevent debris from falling into the open ditch even if the water filter plate 14 is missing, which greatly improves the safety of the open ditch cover. With the mesh buckle 10 and the snap-fit block 11 with spring 13 and positioning post 12, the hanging and disassembly of the anti-fall net 8 is convenient, which facilitates the later inspection, replacement or maintenance of the anti-fall net 8. In addition, the elasticity of the spring 13 can also ensure that the mesh buckle 10 and the snap-fit block 11 are tightly connected, effectively preventing the anti-fall net 8 from falling off.
[0016] Working Principle: In the use of this utility model, firstly, the first cover plate 1 and the second cover plate 2 are moved to the top of the open ditch, and the limiting post 7 on the second cover plate 2 is aligned with the limiting hole 6 on the first cover plate 1 and connected to prevent misalignment of the cover plates during installation. Then, the anti-slip mechanism is installed. Anti-slip strips 4 are provided on the top of the protrusions 3 on the sides of the first cover plate 1 and the second cover plate 2 to increase the friction of the cover plate surface and prevent pedestrians from slipping. Simultaneously, the bolts 9 threaded in the threaded holes on the top of the protrusions 3 are used to further fix the protrusions 3 to the edge of the open ditch, ensuring the stability of the anti-slip strips 4. Next, the water filter plate 14 is installed in the drain trough 5. Then, the fall protection mechanism is installed. First, the fall protection net 8 is placed at the bottom of the first cover plate 1 and the second cover plate 2, and the mesh buckles 10 on the edge of the fall protection net 8 are aligned with the first cover plate 1 and the second cover plate 2. The snap-fit block 11 on the top of the positioning post 12 on the bottom inner wall of the second cover plate 2, under the action of the spring 13 located between the snap-fit block 11 and the cover plate, automatically hooks the mesh buckle 10, realizing the quick installation of the anti-fall net 8. After the open ditch cover plate structure is installed, each component needs to be checked and adjusted to ensure that the installation is firm. During daily use, the drainage grooves 5 opened on the surface of the first cover plate 1 and the second cover plate 2 can drain the water accumulated in the open ditch in time, while the anti-fall net 8 can effectively prevent debris from falling into the open ditch. When the open ditch needs to be cleaned or maintained, the anti-fall net 8 should be disassembled first, and then the snap-fit block 11 should be disengaged from the mesh buckle 10 by compressing the spring 13, so as to facilitate the removal of the anti-fall net 8. After the open ditch cleaning and maintenance work is completed, the anti-fall net 8 should be reinstalled according to the above installation steps.
[0017] 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.
