Description
Technical Field
The utility model relates to a municipal administration articles for use technical field, specifically speaking relate to inspection shaft lid.
Background
The inspection well cover is a cover body placed on an inspection well. The inspection well cover comprises an inspection well cover body, and a drain hole is formed in the inspection well cover body. In the prior art, the central line of the drain hole is vertically arranged, so that the requirement for draining can be met under general conditions, but the requirement for rapid draining cannot be met under the condition of more water accumulation, if the area of the drain hole is increased, the bearing strength of the inspection well cover can be reduced, and the effect of blocking sundries from falling can be reduced.
Disclosure of Invention
The utility model aims at providing an inspection shaft lid that sluicing effect is better, stop debris effectual that falls to above-mentioned shortcoming.
The purpose of the utility model is realized like this: the utility model provides an effectual inspection shaft lid drains, it includes the inspection shaft lid body, the inspection shaft lid body on have a sluicing hole, the sluicing hole have the central line, the sluicing hole have central point's middle sluicing hole and the sluicing hole around the middle sluicing hole, characterized by: the peripheral water drainage holes are arranged in a counterclockwise downward mode.
Furthermore, a groove is formed in the upper surface of the inspection well cover body, and the upper surface of the peripheral water drainage holes are arranged in the groove.
Further, the middle drainage hole has a structure with a large upper surface diameter and a small lower surface diameter.
Further, the projection of the upper opening of the peripheral water drainage hole is arranged beside the lower opening.
Further, a section of guide pipe extending downwards is arranged below the drainage hole.
Furthermore, the inspection well cover body is made of cast iron, and a polyurethane layer which is synthesized together is arranged on the inspection well cover body.
The utility model has the advantages that: the inspection well cover has the advantages of better water drainage effect and good sundry falling prevention effect.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic sectional view taken along the direction a-a in fig. 1.
Fig. 3 is a schematic sectional view taken along the direction B-B in fig. 1.
Wherein: 1. the inspection well cover comprises an inspection well cover body 2, a central line 31, a middle drainage hole 32, peripheral drainage holes 4, a groove 5, a guide pipe 6 and a polyurethane layer.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1, 2 and 3, the inspection well cover with good drainage effect comprises an inspection well cover body 1, wherein the inspection well cover body is provided with a drainage hole, the drainage hole is provided with a central line 2, the drainage hole is provided with a central drainage hole 31 at the central part and peripheral drainage holes 32 around the central drainage hole, and the inspection well cover is characterized in that: the peripheral water drainage holes are arranged in a counterclockwise downward mode.
The utility model is made according to the Kapirome phenomenon, which means that the vortex formed at the water leakage port is always discharged in the anticlockwise rotation when sewage is poured into the water tank in the northern hemisphere, thus accelerating the speed of water flow; because the peripheral drainage holes are arranged anticlockwise downwards, the upper openings and the lower openings of the peripheral drainage holes do not correspond (a dislocation phenomenon exists). Can better prevent sundries from falling down and achieve the purpose of the utility model
Furthermore, a groove 4 is formed in the upper surface of the inspection well cover body, and the upper surface of the peripheral water drainage holes are arranged in the groove.
Thus, the water flow rate is faster.
Further, the middle drainage hole has a structure with a large upper surface diameter and a small lower surface diameter.
Therefore, sundries can be better blocked.
Further, the projection of the upper opening of the peripheral water drainage hole is arranged beside the lower opening.
As shown in fig. 3, a border line a on the right side of the upper opening of the peripheral weep hole is left of a left border line b on the lower side. Thus, the sundry blocking effect is better.
Further, a section of guide pipe 5 extending downwards is arranged below the drain hole.
So set up, the sluicing is faster.
Furthermore, the inspection well cover body is made of cast iron, and a polyurethane layer 6 which is synthesized together is arranged on the inspection well cover body.
By the arrangement, the polyurethane layer can play a role in buffering and protecting the inspection well cover body.
In the description of the present invention, it is to be understood that the terms "upper", "lower", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, which are merely for convenience of description of the present invention, and do not indicate or imply that the indicated device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
The above description is only for the specific embodiment of the present invention, but the structural features of the present invention are not limited thereto, and any person skilled in the art can make changes or modifications within the scope of the present invention.
