The utility model discloses a sewage backflow prevention stopper for a sewer, which comprises a stopper body; the stopper body stops the platform and fixes on the pipeline inner wall including stopping platform and baffle, and the downside end that stops the platform is provided with the protruding connecting block that is used for rotating the pivot of connecting with the baffle is fixed, the inboard of protruding connecting block is provided with movable cavity. The setting that blocks platform and baffle through setting up can effectually prevent the sewage backward flow under the condition that does not influence water downward flow, and the filter screen that sets up simultaneously can effectively prevent bulky impurity from blockking up the sewer, and it has effectively solved the problem that sewer sewage backward flow and easy jam.

Description

Sewage backflow preventer for sewer

Technical Field

The utility model relates to an antifouling water backward flow technical field of sewer specifically is an antifouling water backward flow stopper of sewer.

Background

The sewer is an urban public facility and refers to a pipeline for removing sewage and rainwater from a building; also refers to underground channels for removing sewage and rainwater in cities, factories or villages. Generally, a sewage system is used for collecting and discharging domestic wastewater generated in cities and industrial wastewater generated in industrial sewage.

The drainage pipeline used in the family is also called as a sewer, the existing pipeline has no protection or protective equipment, after the pipeline is blocked, sewage flows back to the first floor or the negative floor through the pipeline, troubles are brought to a user owner, and mice often enter a room through the sewer.

Therefore the utility model provides an antifouling water backward flow stopper of sewer solves above-mentioned problem, can effectually prevent the sewage backward flow, can effectively prevent bulky impurity jam sewer simultaneously.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a sewage backflow stopper is prevented to sewer to solve the problem that proposes in the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

a sewage backflow prevention stopper for a sewer comprises a stopper body; the stopper body stops the platform and fixes on the pipeline inner wall including stopping platform and baffle, and the downside end that stops the platform is provided with the protruding connecting block that is used for rotating the pivot of connecting with the baffle is fixed, the inboard of protruding connecting block is provided with movable cavity.

As a further aspect of the present invention: the inner side of the blocking platform is provided with a through hole, and the area of the through hole is smaller than that of the baffle.

As a further aspect of the present invention: also comprises a filter screen arranged on the inner wall of the pipeline.

As a further aspect of the present invention: the blocking platform, the baffle, the filter screen and the rotating shaft are all formed by injection molding of plastic materials.

As a further aspect of the present invention: and a rotary dirt cleaning port is arranged on the pipeline on the filter screen, and a rotary cover is connected with the rotary dirt cleaning port in an internal thread manner.

As a further aspect of the present invention: the filter screen is positioned above the stopper body.

Compared with the prior art, the beneficial effects of the utility model are that: the setting that blocks platform and baffle through setting up can effectually prevent the sewage backward flow under the condition that does not influence water downward flow, and the filter screen that sets up simultaneously can effectively prevent bulky impurity from blockking up the sewer, and it has effectively solved the problem that sewer sewage backward flow and easy jam.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example one

Referring to fig. 1 to 3, in an embodiment of the present invention, a sewage backflow prevention stopper for a sewer includes a stopper body; the stopper body comprises a stopping platform 1 and a baffle 2; the utility model discloses a sewage treatment device, including baffle 2, baffle 1, movable cavity 6, baffle 2, baffle 1, baffle 2, baffle 1 is fixed at the pipeline inner wall, and the downside end that blocks platform 1 is provided with the bulge connection piece for rotate to connect pivot 3 fixed with baffle 2, thereby realize the rotation of baffle 2, the inboard of bulge connection piece is provided with movable cavity 6, and the setting of movable cavity 6 plays limiting displacement to baffle 2, prevents that baffle 2 from rotating excessively, thereby can't realize baffle.

Preferably, the inner side of the blocking platform 1 is provided with a through hole, and the area of the through hole is smaller than that of the baffle 2, so that the baffle 2 can only rotate to a horizontal state when rotating upwards.

The utility model discloses in the concrete implementation process, still including installing filter screen 5 on the pipeline inner wall, filter screen 5 is used for blockking of bulky impurity, prevents that bulky impurity from blockking up the sewer, and filter screen 5's mounted position is in the play water department who blocks platform 1 throughout and goes up the pipeline in, and concrete mounted position does not do the injecing from the distance that blocks platform 1, can select the installation according to the family condition.

Preferably, block that platform 1, baffle 2, filter screen 5 and pivot 3 all adopt plastics material injection moulding, the anticorrosion, acid and alkali-resistance, long service life.

Example two

In embodiment a concrete implementation process, there is the trouble problem of bulky impurity clearance on the filter screen 5, consequently, this embodiment two optimizes this, and is concrete, is located be provided with rotatory dirt cleaning mouth 4 on the pipeline on the

filter screen

5, 4 threaded connection in rotatory dirt cleaning mouth have the swivel cap, when needs clearance, open the swivel cap, can realize bulky impurity clearance on the filter screen 5, convenient to use through dirt cleaning mouth 4.

It needs the prior art application to explain very much in this application, the setting that blocks platform and baffle through the setting under the condition that does not influence water downward flow, can effectually prevent the sewage backward flow, and the filter screen that sets up simultaneously can effectively prevent bulky impurity jam sewer and be the innovation point of this application, and it has effectively solved the problem that sewer sewage backward flow just blockked up easily.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
