Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of municipal drainage, in particular to an underground well anti-falling object device. Background Art
[0002] Urban drainage facilities are responsible for organizing and discharging urban rainwater. During rainfall, rainwater carries debris such as garbage, weeds, and leaves from the road into stormwater wells, causing blockages. Therefore, before the flood season arrives each year, a large amount of manpower and material resources are required for routine cleaning and dredging. At the same time, with global warming and the frequent occurrence of extreme weather, it has become common practice to open urban rainwater grates to accelerate drainage during summer rainstorms. The opening of rainwater grates can easily cause pedestrians to fall into wells, greatly increasing municipal safety hazards. In addition, in addition to drainage facilities, cities also have common concealed engineering facilities such as sewage facilities, cable facilities, septic tanks, and machine wells. Damage to the manhole covers of these facilities due to disrepair, abandonment, or loss will lead to frequent risks of falling objects and pedestrians falling into wells, causing property losses and major safety hazards to people.
[0003] The existing underground well anti-falling device has a relatively simple structure, which only fixes a net bag at the wellhead. The size of the net bag is relatively fixed and has poor adaptability, resulting in strict requirements on the well diameter size; and the fixed net bag is difficult to disassemble, resulting in garbage and waste accumulated on the net bag being difficult to clean; in addition, the mesh size of the existing net bag is large and not elastic, so it is difficult to ensure effective collection of some smaller garbage, which will still cause blockage of the underground well. Summary of the Invention
[0004] The utility model aims to provide an underground well anti-falling device in response to the defects of the prior art.
[0005] In order to achieve the above purpose, the present invention can adopt the following technical solutions:
[0006] The underground well falling object prevention device described in the present invention includes an annular support frame fixed on the edge of the underground wellhead, and an elastic net bag covered in the underground wellhead; a plurality of ear plates are evenly distributed circumferentially on the inner upper edge of the annular support frame, and a connecting buckle is clamped on the ear plate, and the connecting buckle is composed of an upper buckle ring and a lower buckle ring to form an "8" buckle structure, and openings are provided on the upper buckle ring and the lower buckle ring, and a self-rebounding locking rod is hinged on the opening, and hanging plates clamped on the lower buckle ring are evenly distributed circumferentially on the upper edge of the elastic net bag; a stainless steel pull rope passing through the center of the annular support frame is connected between two opposite ear plates in a group, and a spring rope whose lower end is connected to the bottom center of the elastic net bag is connected at the center of the stainless steel pull rope.
[0007] Furthermore, a vertically downward core shaft is provided at the bottom of the upper buckle ring, and a horizontally rotating ring that is clamped on the core shaft is provided at the top of the lower buckle ring. The upper buckle ring and the lower buckle ring are connected as a whole through the core shaft and the ring rotation, so that the lower buckle ring can rotate arbitrarily in the horizontal direction.
[0008] Furthermore, spring buckles are provided at both ends of the stainless steel pull rope and both ends of the spring rope. The two ends of the stainless steel pull rope are clamped on the two opposite ear plates through the spring buckles, and the two ends of the spring rope are respectively clamped on the center of the stainless steel pull rope and the center of the bottom of the elastic net bag through the spring buckles, which facilitates the installation and disassembly of the stainless steel pull rope and the spring rope.
[0009] The advantage of the utility model is that it can be widely used in various underground wells of existing municipal drainage projects, and is adaptable to underground wells of different well diameters and shapes; at the same time, the connecting buckles hung on the inner ear plates of the annular support frame, combined with the hanging pieces uniformly distributed along the circumference on the edge of the elastic net bag, can also facilitate the installation and disassembly of the elastic net bag, effectively preventing pedestrians from falling into the well, and allowing the debris collected in the elastic net bag to be quickly removed; in addition, the elastic net bag can not only increase the carrying capacity of debris, but also reduce the mesh size as much as possible under the action of the rebound contraction force, effectively preventing smaller garbage from falling through the mesh holes, and improving the debris interception capability.

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0016] like Figure 1-3 As shown, the underground well falling object prevention device described in the utility model includes an annular support frame 1 fixed on the edge of the underground wellhead. The annular support frame 1 can be processed into any annular structure such as a circular ring, a rectangular ring, etc. according to the shape of the wellhead of the underground well, so that it is widely applicable to various underground wells in existing municipal drainage projects, and is suitable for underground wells of different well diameters and different shapes.
[0017] A plurality of ear plates 2 are evenly distributed along the circumference of the inner edge of the annular support frame 1. The ear plates 2 are arranged horizontally, and each ear plate 2 is hung with a connecting buckle 3. Figure 5 As shown, the connecting buckle 3 is composed of an upper buckle ring 3.1 and a lower buckle ring 3.2. Specifically, a vertically downward core shaft 3.3 is provided at the bottom of the upper buckle ring 3.1, and a sleeve 3.4 that can be adapted to be sleeved and rotated horizontally on the core shaft 3.3 is provided at the top of the lower buckle ring 3.2, so that the upper buckle ring 3.1 and the lower buckle ring 3.2 are rotatably connected as a whole through the core shaft 3.3 and the sleeve 3.4, forming an "8" buckle structure, ensuring that the lower buckle ring 3.2 can rotate arbitrarily in the horizontal direction; in addition, an opening 3.5 for inserting an object should be provided on the upper buckle ring 3.1 and the lower buckle ring 3.2 of each connecting buckle 3, and a self-rebounding locking rod 3.6 is hinged on the opening 3.5. When the outer side of the self-rebounding locking rod 3.6 is subjected to force, it will rotate inward to open the opening 3.5. When the self-rebounding locking rod 3.6 is released from the force, it will automatically rotate outward to rebound and close the opening 3.5.
[0018] The cam 3 is provided with a plurality of hooks 5 on the circumference of the mouth of the elastic net bag 4, and each hook has a hook hole 3.2 on the lower buckle 3.2, so that the elastic net bag 4 can be easily connected with the annular support frame 1, and the installation and removal of the elastic net bag 4 are convenient. The debris collected in the elastic net bag 4 can be quickly cleared away. At the same time, the elastic net bag 4 can also increase the carrying capacity of the debris under its own elastic action, and reduce the mesh size as much as possible under the action of its own rebound and contraction force, effectively preventing small garbage from falling from the mesh, improving the debris interception ability, and effectively preventing pedestrians from falling into the well.
[0019] In addition, in order to further improve the carrying capacity of the elastic net bag 4, a stainless steel pull rope 6 passing through the center of the annular support frame 1 is connected between one set of two opposite ear plates 2, and a spring rope 7 whose lower end is connected to the bottom center of the elastic net bag 4 is connected to the center of the stainless steel pull rope 6. Figure 4As shown, both ends of the stainless steel pull rope 6 and both ends of the spring rope 7 are provided with spring buckles 8 for convenient hanging. The two ends of the stainless steel pull rope 6 can be hung on the two opposite ear plates 2 through the spring buckles 8, and the two ends of the spring rope 7 can be hung on the center of the stainless steel pull rope 6 and the center of the bottom of the elastic net bag 4 respectively through the spring buckles 8, which facilitates the installation and disassembly of the stainless steel pull rope 6 and the spring rope 7.
