Technical Field

[0001] The utility model relates to the technical field of manhole covers, in particular to a manhole cover which is convenient and safe for flood discharge. Background Art

[0002] When urban roads encounter floods or heavy rains, the water flow will push the garbage on the ground onto the sewer manhole covers on both sides of the road, which will cause the garbage to block the drainage outlet, further making it impossible for the accumulated water to be discharged, affecting normal traffic. The current common solution is to open the sewer manhole cover to release the water and put the manhole cover aside, which creates a dangerous situation. The deep drainage hole of the sewer will bring great safety hazards to pedestrians, cyclists or vehicles, especially at night. For this reason, we propose a manhole cover that is convenient and safe to discharge flood water to solve the problems raised in the above background technology. Utility Model Content

[0020] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-4 As shown, a manhole cover for convenient and safe flood discharge includes a manhole cover body 1, a plurality of leakage holes 2 arranged evenly are provided on the manhole cover body 1, a grille cover is provided on the manhole cover body 1, and the grille cover is arranged on the upper outer side of the leakage holes 2; the grille cover includes a plurality of supporting columns 3 and a plurality of connecting beams 4, the plurality of supporting columns 3 are evenly arranged on the outer side of the manhole cover body 1, and the connecting beams 4 are arranged above the supporting columns 3; the cross sections of the supporting columns 3 and the connecting beams 4 are both circular. This design has a simple structure and is easy to use. Through the cooperation of the manhole cover body 1 and the grille cover and other components, when encountering floods or heavy rains and needing to discharge flood water, it is only necessary to flip the manhole cover instead of removing the manhole cover and putting it aside. Garbage can be effectively blocked to ensure rapid discharge of flood water. The grille cover forms an outwardly convex structure on the manhole cover, which will not cause pedestrians to fall into the sewer, and has high safety. It can also be flipped under normal use to prevent obstruction to the road, and can fully meet the city's demand for manhole covers.

[0022] In order to ensure the structural strength of the grille cover, the support columns 3 and the connecting beams 4 are fixed by welding. Moreover, the support columns 3 and the connecting beams 4 can both be cast iron pipes.

[0023] A plurality of circular openings matching the supporting columns 3 are provided on the outer side of the manhole cover body 1, and the lower part of the supporting columns 3 is inserted into the circular openings to fix the lower part of the supporting columns 3, thereby ensuring the connection strength between the grille cover and the manhole cover to improve the use effect of the manhole cover.

[0024] The manhole cover body 1 is in the shape of a rectangular parallelepiped, and the leakage hole 2 is in the shape of a long strip. The length direction of the manhole cover body 1 is perpendicular to the length direction of the leakage hole 2. The circular openings on the front and rear sides of the manhole cover body 1 are arranged at equal intervals along the length direction of the leakage hole 2. The circular openings on the left and right sides of the manhole cover body 1 are arranged between two adjacent leakage holes 2, so that the grille cover is arranged on the outside of the leakage hole 2, and can reduce the impact on the structural strength of the manhole cover body 1 itself.

[0025] The manhole cover body 1 is a cast iron manhole cover, and the lower part of the support column 3 is welded and fixed to the cast iron manhole cover to further ensure the connection strength between the grille cover and the manhole cover.

[0026] When this design is in use, a grille cover is provided on the manhole cover body 1. When encountering floods or heavy rains and needing to discharge flood water, the manhole cover body 1 can be flipped 180° so that the grille cover is located above the manhole cover body 1 and protrudes from the road surface, thereby effectively blocking garbage and the like and ensuring rapid discharge of flood water. In addition, since the grille cover forms an outwardly convex structure, pedestrians can be prevented from falling into the sewer, thereby having higher safety. During normal use, the manhole cover body 1 can also be flipped so that the grille cover is located below the manhole cover body 1 to prevent obstruction of the road and affect the normal flow of traffic, thereby fully meeting the city's demand for manhole covers.

[0027] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
