Description

Technical Field

[0001] The utility model relates to a sewage interception and overflow device for drainage pipelines, belonging to the technical field of sewage treatment equipment. Background Technique

[0002] In the urban drainage system, the initial rainwater is the focus of attention for rainwater pollution. The initial rainwater refers to the rainwater at the beginning of rainfall, generally referring to the precipitation with a thickness of 10 - 15 mm on the ground that forms surface runoff. Since a large amount of polluting gases such as acidic gases in the air, automobile exhaust, and factory waste gas are dissolved in the rainwater at the beginning of rainfall, and after falling to the ground, due to washing the roof, asphalt concrete road, etc., a large amount of pollutants are contained in the initial rainwater, and the pollution degree of the initial rainwater is relatively high, even exceeding that of ordinary urban sewage. The initial rainwater often directly enters the urban drainage system through the rainwater inlet, bringing a certain degree of pollution to the urban drainage system.

[0003] Chinese Patent No.: CN219011439U mentions a sewage interception and overflow device for drainage pipelines. By arranging a box body inside the rainwater inlet and installing the box body on the structure wall at the end of the drainage pipeline, the overflow chamber inside the box body is connected to the drainage pipeline through a drainage port, and the filter bricks are embedded in the slots on one side of the box body. The initial rainwater enters from the rainwater inlet, and after being treated by the filter bricks, it enters the overflow chamber from the filtration outlet and then is discharged into the drainage pipeline, forming filtration of the initial rainwater entering the rainwater inlet and improving the treatment effect of the initial rainwater. However, the rainwater inlet in this device has a certain depth. When the rainwater drives garbage and impurities into the rainwater inlet, the rainwater is discharged into the drainage pipeline through the filter bricks, while the garbage and impurities will accumulate in the rainwater inlet, which is inconvenient for people to clean. At the same time, the rainwater at the bottom of the rainwater inlet cannot be discharged into the drainage pipeline through the filter bricks, and it will ferment and stink together with the garbage and impurities after a long time of accumulation. Now, there is an urgent need for a sewage interception and overflow device for drainage pipelines to solve the above problems. Content of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a sewage interception and overflow device for drainage pipelines to solve the problems mentioned in the above background technique. The structure of the utility model is reasonable and has good practicability. Adopting an interception and filtration structure, it can filter the rainwater multiple times and intercept and collect the garbage and impurities it carries, thus facilitating the centralized treatment by the staff, and preventing the rainwater from accumulating and fermenting and stinking, and being able to discharge it, which is conducive to popularization and use.

[0005] To achieve the above object, the utility model is realized through the following technical solutions: A sewage interception and overflow device for drainage pipes, comprising a rectangular groove, a high-strength interception grille, a garbage filter screen and an impurity filter plate. The rectangular grooves are arranged on the upper left and right sides of the rainwater inlet. A diversion slope is arranged at the lower end inside the rainwater inlet. A drainage pipe is vertically arranged on the right side at the lower end inside the rainwater inlet, and a filter brick is longitudinally arranged on the left end face of the drainage pipe. Strip plates are fixed to the left and right ends of the high-strength interception grille. The two strip plates are respectively located in the two rectangular grooves, and the high-strength interception grille is horizontally located at the upper end inside the rainwater inlet. First connecting rods are longitudinally fixed around the lower end of the high-strength interception grille. The garbage filter screen is horizontally fixed to the lower ends of the plurality of first connecting rods through a plurality of first flange bolts. A second connecting rod is longitudinally fixed in the middle of the lower end of the garbage filter screen. The impurity filter plate is horizontally fixed to the lower end of the second connecting rod through a second flange bolt. An impurity filter frame is integrally fixed to the upper end of the impurity filter plate.

[0006] Further, an inclined grille is inclined and fixed to the upper end of the filter brick.

[0007] Further, buckling grooves are formed in the upper ends of the two strip plates.

[0008] Further, the garbage filter screen is directly above the impurity filter frame.

[0009] Further, the edges of the garbage filter screen and the impurity filter frame are both in contact with the inner surface of the rainwater inlet.

[0010] The beneficial effects of the utility model: For the sewage interception and overflow device for drainage pipes of the utility model, because the utility model adds a diversion slope, a filter brick, an inclined grille, a high-strength interception grille, a first connecting rod, a first flange bolt, a garbage filter screen, a second connecting rod, an impurity filter frame and an impurity filter plate, through our design improvement and actual use, it shows that this device adopts an interception and filtration structure, can filter rainwater multiple times, and can intercept and collect the garbage and impurities it carries, thus facilitating the centralized treatment by staff, and will not cause the rainwater to accumulate and ferment and stink, and can discharge it, which is conducive to popularization and use.

Specific embodiments

[0016] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] Please refer to Figures 1-3 , the present utility model provides a technical solution: a sewage interception and overflow device for a drainage pipeline, including a rectangular groove 2, a high-strength interception grille 9, a garbage filter screen 12 and an impurity filter plate 16. The rectangular groove 2 is opened on the left and right sides of the upper end of the rainwater inlet 1. A diversion slope 3 is arranged at the lower end inside the rainwater inlet 1. A drainage pipeline 4 penetrates through the right side of the lower end inside the rainwater inlet 1. And a filter brick 5 is longitudinally arranged on the left end face of the drainage pipeline 4. Strip plates 7 are fixed at both the left and right ends of the high-strength interception grille 9. The two strip plates 7 are respectively located in the two rectangular grooves 2. And the high-strength interception grille 9 is horizontally located at the upper end inside the rainwater inlet 1. First connecting rods 10 are longitudinally fixed around the lower end of the high-strength interception grille 9. The garbage filter screen 12 is horizontally fixed at the lower ends of the plurality of first connecting rods 10 through a plurality of first flange bolts 11. A second connecting rod 13 is longitudinally fixed in the middle of the lower end of the garbage filter screen 12. The impurity filter plate 16 is horizontally fixed at the lower end of the second connecting rod 13 through a second flange bolt 14. An impurity filter frame 15 is integrally fixed at the upper end of the impurity filter plate 16. This design solves the problem that garbage and impurities in the original device will accumulate in the rainwater inlet, which is inconvenient for people to clean, and will ferment and stink together with the garbage and impurities after long-term accumulation.

[0018] As the first embodiment of the present utility model: an inclined grille 6 is inclined and fixed at the upper end of the filter brick 5. By adding the inclined grille, the rainwater overflowing to the upper end of the filter brick 5 can be discharged. And the filter brick 5 can filter the rainwater in the rainwater inlet 1. Thus, the rainwater in the rainwater inlet 1 can flow through the filter brick 5 and into the drainage pipeline 4. At the same time, the setting of the diversion slope 3 makes the rainwater in the rainwater inlet 1 not accumulate, and all of it will flow to the left side of the filter brick 5.

[0019] Both upper ends of the two strip plates 7 are provided with buckling grooves 8. Through the provided buckling grooves 8, it is convenient for the staff to lift the strip plates 7 and the high-strength interception grille 9. The garbage filter screen 12 is located directly above the impurity filter frame 15. The edges of the garbage filter screen 12 and the impurity filter frame 15 are both attached to the inner surface of the rainwater inlet 1. The added garbage filter screen 12 can filter the garbage passing through the high-strength interception grille 9, and the settings of the impurity filter frame 15 and the impurity filter plate 16 can filter and collect the impurities passing through the garbage filter screen 12.

[0020] As the second embodiment of the present utility model: The external rainwater will first flow into the rainwater inlet 1 through the high-strength interception grille 9, and the width of the opening of the high-strength interception grille 9 is five centimeters, which will not affect people walking on the high-strength interception grille 9. The garbage filter screen 12 can filter the garbage passing through the high-strength interception grille 9, and the impurity filter frame 15 and the impurity filter plate 16 can filter and collect the impurities passing through the garbage filter screen 12, so that the rainwater will not carry garbage and large impurities and fall to the lower end inside the rainwater inlet 1. The setting of the diversion slope 3 makes the rainwater in the rainwater inlet 1 not accumulate, and all of it will flow to the left of the filter brick 5. Then the rainwater in the rainwater inlet 1 can pass through the filter brick 5 and flow into the drainage pipe 4. When there is a lot of rainwater in the rainwater inlet 1 and it submerges the inclined grille 6, the overflowing rainwater in the rainwater inlet 1 will flow into the drainage pipe 4 through the opening of the inclined grille 6. After use, hold the two buckling grooves 8 and lift upward, and the high-strength interception grille 9, the garbage filter screen 12, the impurity filter frame 15 and the impurity filter plate 16 will be removed from the rainwater inlet 1, which is convenient for the staff to clean the garbage and impurities filtered by the garbage filter screen 12, the impurity filter frame 15 and the impurity filter plate 16.
