Description

Technical Field

[0001] The utility model relates to the technical field of municipal drainage equipment, in particular to a manhole cover for municipal drainage which is anti-falling and anti-automatic flipping. Background Art

[0002] There are more and more underground pipelines in cities, and accordingly, various inspection wells and manhole covers also play an important role. Inspection wells are generally located at pipeline intersections, bends, places where pipe diameters or slopes change, and at certain intervals on straight pipe sections to facilitate regular inspection of ancillary structures.

[0003] The existing combination of the well seat and the cover is installed in the well seat by the deadweight of the cover. This installation method is not secure. When a heavy object is pressed on the edge of the cover, it is easy to cause the cover to flip and deflect, thereby causing the well seat and the cover to separate, posing a safety hazard. At the same time, this installation method can be disassembled at will by others, making it easy for theft and leaving the well seat open. Utility Model Content

[0004] The problem solved by the utility model is to provide a municipal drainage anti-fall and anti-automatic flip-up manhole cover, which solves the existing combination of a manhole seat and a cover body. The cover body is installed in the manhole seat by its own weight. This installation method has an unstable connection. When a heavy object presses on the edge of the cover body, it is easy to cause the cover body to flip and deflect, and then cause the manhole seat and the cover body to separate, posing a safety hazard. At the same time, this installation method can be disassembled at will by others, which is easy to be stolen, resulting in the technical problem that the manhole seat is in an open state.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A municipal drainage anti-fall and anti-automatic flip-up manhole cover comprises a manhole seat and a cover body. The cover body is detachably mounted on the manhole seat, a support ring is provided inside the manhole seat, a plurality of clamping blocks are mounted at equal angles on the inner wall of the manhole seat, an anti-fall net is mounted on the bottom of the manhole seat, a plurality of right-angled grooves are opened at equal angles on the side wall of the cover body, and the clamping blocks are engaged with the right-angled grooves.

[0007] Preferably, a limiting hole is provided on the clamping block.

[0008] Preferably, the top side of the cover body is provided with anti-slip grooves, and the top of the cover body is symmetrically provided with adjustment holes.

[0009] Preferably, a ring groove is provided on the top of the cover body, a ring plate is installed in the ring groove, and a threaded hole is provided on the ring plate, and a bolt is threadedly installed in the threaded hole.

[0010] Preferably, the bottom side of the ring plate is provided with plug posts at equal angles, and the bottom ends of the plug posts are located in the right-angle grooves.

[0011] Preferably, an inner cavity is opened at an equal angle inside the cover body, the plug post is located inside the inner cavity and a movable plate is installed, and a spring is sleeved on the outer side of the plug post and located between the top wall of the inner cavity and the movable plate.

[0012] The beneficial effects of the present invention are as follows: through the cooperation between the clamping block of the well seat and the right-angle groove of the cover body, the well seat and the cover body are limited and initially installed; through the up and down movement of the ring plate and the elastic deformation of the spring, the plug column is easily inserted into the limiting hole of the clamping block, thereby reinforcing the connection between the well seat and the cover body, avoiding the cover body from tipping over and moving during use, ensuring that the cover body is always located on the well seat during the non-maintenance municipal pipeline connection stage, avoiding pedestrians or vehicles from falling.

[0018] The following will be combined with the accompanying 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.

[0019] Specific examples are given below.

[0020] See also Figures 1 to 3When the well seat 1 and the cover body 2 are assembled, the card block 4 is located in the horizontal section.

[0021] The top of the cover body 2 is provided with an annular groove 10, and a ring plate 11 is installed in the annular groove 10. The ring plate 11 is located in the annular groove 10. At this time, the top side of the ring plate 11 is translated with the top side of the cover body 2 to avoid the appearance of a convex structure, and a threaded hole 12 is provided on the ring plate 11. A bolt 13 is installed in the threaded hole 12. When the bolt 13 rotates downward in the threaded hole 12, the bottom end of the bolt 13 acts on the cover body 2. As the bolt 13 rotates, the ring plate 11 is driven to move upward, and the plug column 14 located in the right-angle groove 9 is received in the inner cavity 15, and the spring is pressed against the movable plate 16. 17 is compressed, and after the disassembly and assembly are completed, the bolt 13 is removed from the threaded hole 12, and the column 14 is installed at equal angles on the bottom side of the ring plate 11, and the bottom end of the column 14 is located in the right-angle groove 9, and the cover body 2 is provided with an inner cavity 15 at equal angles. The column 14 is located in the inner cavity 15 and a movable plate 16 is installed. A spring 17 is installed on the outside of the column 14 and between the top wall of the inner cavity 15 and the movable plate 16. The compressed spring 17 returns to its original state, driving the ring plate 11 and the column 14 to move downward, and the column 14 is inserted into the limiting hole 5 of the block 4.

[0022] Working principle: Install the bolt 13 into the threaded hole 12, and the bottom end of the bolt 13 acts on the cover body 2. As the bolt 13 rotates, the ring plate 11 is driven to move upward, and the column 14 located in the right-angle groove 9 is received into the inner cavity 15, and the spring 17 is compressed by the movable plate 16. At this time, the cover body 2 is installed into the well seat 1. First, the block 4 enters the top of the vertical section of the right-angle groove 9, and then the cover body 2 is rotated, and the block 4 is stuck in the horizontal section of the right-angle groove 9. At this time, unscrew the bolt 13, and the compressed spring 17 returns to its original state, driving the ring plate 11 and the column 14 to move downward, and the column 14 is inserted into the limiting hole 5 of the block 4 to realize the installation of the well seat 1 and the cover body 2.

[0023] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
