Description

Filtering type drainage well cover

Technical Field

The technical scheme of the invention relates to a filtering type drainage well cover, in particular to equipment adopting the well cover, a rubber gasket, a filter screen, a chain and a sewer pipeline, and belongs to the field of water supply and drainage equipment.

Background

At present, when the plumbing well lid is installed on the mouth of sewer, be usually with well lid base and the connection of sewer mouth upper portion direct contact, nevertheless because well lid and sewer mouth have certain deflection at the in-process of preparation, direct rigid connection is unstable, the problem that rocks appears easily. Simultaneously, in municipal administration plumbing engineering, the stolen thief of sewer well lid is stolen more easily, or when rainwater weather needs open the sewer well lid and carry out quick drainage, at this moment the passerby falls through very easily, has the potential safety hazard.

The security of current drainage well lid when using is relatively poor, and when the water under the drainage well lid climbs drainage well lid for the drainage well lid appears rolling easily and opens the phenomenon, when the pedestrian steps on drainage well lid under the state of overflowing, falls easily to the sewer in, has the potential safety hazard. And traditional drainage well lid self does not have filtration for drainage well lid makes drainage well lid sewer under the well lid appear blocking phenomenon easily in long-time use, thereby has increased the mediation number of times of sewer, has brought the inconvenience for the user.

To above-mentioned problem, the event needs to design a device, and it can solve the sewer cover and appear rocking problem easily after the installation, can also prevent that the pedestrian from falling, reduces the potential safety hazard, still has filtration simultaneously, prevents that the obstructed phenomenon from appearing in the sewer.

Disclosure of Invention

The invention aims to overcome the defects of the prior art, and provides a filtering type drainage well cover which can solve the problem that a sewer cover is easy to shake after being installed, improves the safety coefficient, has a filtering structure, prevents the sewer from being blocked, and overcomes the defects in the prior art.

The invention is realized by the following technical scheme:

the filtering type drainage well cover comprises a well cover body, a rubber gasket, a filter screen, a lock chain and a sewer pipe, wherein the well cover body is provided with a lock chain buckle A and a convex edge, the pipe wall of the sewer pipe is provided with a lock chain buckle B and a threaded hole, and the filter screen is provided with a filter screen buckle. The rubber gasket is fixedly installed on a sewer line, the well cover is installed on the sewer line through the convex edge, the filter screen is communicated with the filter screen fastener and the threaded holes in the pipe wall of the sewer line are installed on the sewer line below the well cover, one end of the chain is connected with the chain fastener A, and the other end of the chain is connected with the chain fastener B.

The upper part of the well cover is provided with a well cover opening and sparse small holes.

The filter screen is made of an iron net, and a filter screen notch is formed in the filter screen.

The wall of the sewer pipeline is coated with a red fluorescent powder layer.

The components of the filtering type drainage well cover are well known to those skilled in the art and can be obtained by well-known methods, and the connecting method of the components can be mastered by those skilled in the art.

The anti-falling device has the beneficial effects that the problem that the sewer cover is easy to shake after being installed is solved, the pedestrian can be prevented from falling, the potential safety hazard is reduced, and meanwhile, the anti-falling device is also provided with the filtering structure, so that the phenomenon that the sewer is blocked is prevented. The red fluorescent powder layer is coated on the pipe wall of the sewer pipeline, so that the alertness of pedestrians and vehicles walking at night can be improved, and the probability that the pedestrians and vehicles fall down the sewer pipeline at night is reduced.

Detailed Description

The invention is further described with reference to the following figures and examples.

As shown in fig. 1 to 5, the well cover device for water supply and drainage of the invention comprises a well cover 1, a rubber gasket 3, a filter screen 4, a chain 5 and a sewer pipe 2, wherein the well cover 1 is provided with a chain fastener a103 and a convex edge 104, the pipe wall of the sewer pipe 2 is provided with a chain fastener B201 and a threaded hole 202, and the filter screen 4 is made of an iron net and is provided with a filter screen notch 402 and a filter screen fastener 401. Rubber packing ring 3 fixed mounting is on sewer pipe 2, and on well lid 1 installed the rubber packing ring 3 on sewer pipe 2 through protruding edge 104, rubber packing ring 3 played the cushioning effect for well lid 1 takes place to rock when preventing to have vehicle or pedestrian to pass through. The filter screen 4 is installed on the sewer pipe 2 below the well lid 1 through the filter screen buckle 401 and the threaded hole 202 on the pipe wall of the sewer pipe 2, and is used for preventing pedestrians from falling off and blocking the sewer pipe 2 due to the fact that large impurities enter the sewer pipe 2, and the filter screen notch 402 can prevent the filter screen 4 from being clamped by the lock chain 5, so that the filter screen 4 can be taken out conveniently. One end of the lock chain is connected with the lock chain buckle A103, and the other end of the lock chain is connected with the lock chain buckle B201, so that the well lid 1 is fastened, the theft and the flushing by the large water can be prevented.

1 upper portion of well lid is equipped with well lid opening 101 and sparse aperture 102, and well lid opening 101 is convenient for the staff and is opened well lid 1, and sparse aperture 102 can accelerate the emission of ground rainwater, and under the condition of rain in the lower, unnecessary moisture can be discharged through aperture 102 fast, has reduced the number of times that the staff comes to open well lid 1. The wall of the sewer pipeline 2 is coated with the red fluorescent powder layer 6, at night, the well cover 1 is stolen or opened, so that the safety potential hazard to pedestrians and vehicles is great, at the moment, the red fluorescent layer can play a good warning role for the pedestrians and the vehicles, and the risk of falling to the sewer pipeline 2 is reduced.

Therefore, the scope of the present invention should not be limited to the disclosure of the embodiments, but includes various alternatives and modifications without departing from the scope of the present invention, which is defined by the claims of the present patent application.
