Description

Safety well lid for drainage and overhaul

Technical Field

The utility model relates to the technical field of urban waterlogging drainage, in particular to a safety well cover for waterlogging drainage and overhaul.

Background

The well lid is a closed part leading to the top of an access of municipal underground facilities, and the well lid is required to be installed in places where public facilities such as tap water, telecommunication, electric power, gas, heat, fire protection, sanitation and the like are installed.

When water is accumulated on the road surface due to a large amount of water, in order to accelerate the drainage of the accumulated water, the well cover on the road surface is often lifted to be placed on the road side, so that the dredging of the accumulated water is accelerated, the well cover is forgotten to be restored to the original position after the accumulated water is drained, the well mouth is exposed on the road surface, and particularly at night, a driver cannot see clearly or hurriedly to the road, and is easily trapped in the road, which is undoubtedly a large traffic trap; in addition, when the urban rainwater is excessively accumulated, under the water pressure, the lifting of the manhole cover is time-consuming and labor-consuming, in addition, if heavy rainstorm occurs in summer, the conventional drainage system is often paralyzed, and if accumulated water cannot be drained timely, urban traffic is affected, and serious urban waterlogging is caused; and when taking place waterlogging drainage speed is limited, if with the direct design great of outlet, leads to the peculiar smell in the sewer pipe to rush out easily, influences the living environment.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the problems that in the prior art, a safety well cover for drainage and overhaul is not easy to lift under water pressure, peculiar smell rushes out of a drainage port, and drainage paralysis in rainstorm weather causes urban inland inundation.

Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.

Example 1

The utility model provides a drainage overhauls uses safety well lid, as shown in fig. 1 to fig. 2, including well frame 1, first drainage network 3 and second drainage network 2 have been laid respectively at the top intermediate position and both ends of well frame 1, be equipped with first drainage chamber 4 under first drainage network 3, first drainage mouth 5 has been seted up respectively on the both sides wall of first drainage chamber 4, it is equipped with second drainage chamber 6 that is used for preventing that the peculiar smell from scurrying to be located between two second drainage network 2 at the periphery of first drainage chamber 4, be equipped with down water hole 10 in the bottom of second drainage chamber 6, the below that is located first drainage chamber 4 on the both sides wall of second drainage chamber 6 corresponds and is equipped with second outlet 7. Through setting up first drainage chamber 4 and the second drainage chamber 6 of establishing each other cover to and the first drainage mouth 5 and the second drainage mouth 7 of upper and lower setting, the rainwater is through discharging away through lower water hole 10, prevents with this that the peculiar smell in the sewer from leading to and rushing out first drainage net 3, influences living environment.

Be equipped with hydraulic plate 9 respectively under every second water drainage network 2 below of being located second outlet 7, hydraulic plate 9's one end articulates on the lateral wall of water derrick 1, set up fluted 14 respectively at hydraulic plate 9's the other end, it is equipped with limiting plate 15 to slide in recess 14, be equipped with compression spring 16 between limiting plate 15 and the inner wall of recess 14, another side at limiting plate 15 is fixed with tip for curved kelly 13, arc draw-in groove 12 has been seted up with kelly 13 corresponding position on the lateral wall of second drainage chamber 6, and the arc end of kelly 13 extends recess 14 and the card is established in draw-in groove 12. When taking place ponding, during water level foam second outlet 7, the jam bar 13 of arc end is deviate from arc draw-in groove 12 owing to receiving pressure to water pressing plate 9, and reset spring 8 is tensile under compression spring's 16 effect, makes water pressing plate 9 open, and rivers increase a offal passageway for drainage rate prevents city waterlogging ponding.

And a return spring 8 is arranged between the middle part of the upper surface of the water pressure plate 9 and the side wall of the water derrick 1. When the rainwater is less or clear weather, reset spring 8 resets, drive water pressure plate 9 rebound, remove the extrusion of the arc end of in-process kelly 13 by second drainage chamber 6 lateral wall, make compression spring 16 shrink drive kelly 13 and limiting plate 15 shrink to recess 14 in, remove to draw-in groove 12 department, compression spring 16 resumes elasticity, make kelly 13 card go into in draw-in groove 12, accomplish the reseing of water pressure plate 9, can also avoid the peculiar smell directly to scurry out from second drainage network 2 simultaneously.

The top that lies in water pressure plate 9 on the lateral wall of second drainage chamber 6 is equipped with stopper 11, and stopper 11 can make water pressure plate 9 accurate quick the reseing.

The working mode of the utility model is as follows: in light rain weather, rainwater flows downwards through the first drainage network 3 and the second drainage network 2, the rainwater passing through the first drainage network 3 flows to the second drainage cavity 6 through the first drainage port 5, the rainwater passing through the second drainage network 2 flows to the second drainage cavity 6 through the second drainage port 7, and then flows away through the drain holes 10 together with the rainwater flowing to the second drainage cavity 6 through the drainage network 3; when meeting heavy rain weather, the rainwater is gathered in second drainage chamber 6 and when flooding second outlet 7 department, and the one end pressurized of water pressure plate 9 is broken away, increases sewer passage for the discharge rate of ponding prevents that drainage system is paralysed, has also avoided the people to open the well lid simultaneously, wastes time and energy and causes the potential safety hazard.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or that certain features may be replaced by equivalents thereof; any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
