Obviously, the described embodiments are part of the present application Examples, not all examples. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

Example:

Referring to Figures 1-3, the anti-blocking structure of pipelines for municipal engineering water supply and drainage includes a drainage well 1 and a water inlet pipe 2, and the water inlet pipe 2 is connected to one side of the drainage well 1. The inner walls on both sides of the drainage well 1 are provided with chute 16, and the inner surface of the chute 16 is slidably connected with a slider 18, and the outer surface of the side of the slider 18 away from the inner side wall of the drainage well 1 is welded with a filter screen 2 12. Two 12 are positioned at water inlet pipe 2 lower sides. The lower surface of the filter screen two 12 is painted with glue 17, the filter screen two 12 is connected with a foam block 15 through the glue 17, a hole 7 is provided on one side of the drainage well 1, and a card slot 10 is provided on the inner wall of the upper side of the hole 7. The 7 places are connected with the sewage collecting pipe 5, and the end of the sewage collecting pipe 5 away from the drainage well 1 is bent upward. Drainage well 1 is provided with retaining groove 11 near the side wall of hole 7, and the inside of retaining groove 11 is slidably connected with blocking plate 13, and the lower surface of blocking plate 13 is welded on the upper surface of slide block 18, and the upper surface of blocking plate 13 The surface abuts against the top of the inner wall of the slot 10, the outer surface of the lower end of the sewage collection pipe 5 is connected with a connecting pipe 4, the connecting pipe 4 is vertically arranged, and the side of the connecting pipe 4 far away from the sewage collection pipe 5 is connected with a drain pipe 3 for drainage One end of the pipe 3 near the water inlet pipe 2 is connected to the inside of the drain well 1, and the drain pipe 3 is positioned at the lower side of the filter screen two 12.

When there is too much sludge accumulated on the upper surface of the filter screen 12, the filter holes inside the filter screen 12 will be blocked, so that the sewage will stay on the upper end of the filter screen 12, and at the same time, foam will be caused due to the lack of water flow at the lower end of the filter screen 212. The buoyancy of the block 15 disappears, thereby driving the blocking plate 13, the slide block 18 and the filter screen two 12 to move downward. In addition, when the blocking plate 13 moves downward, the internal water flow of the drainage well 1 can flow to the The inside of the drainage pipe 3, so as to avoid as far as possible that the drainage well 1 is blocked and the sewage cannot be discharged.

Referring to Figure 1-2, the end of the sewage collection pipe 5 away from the drainage well 1 is threaded, and the internal thread of the sewage collection pipe 5 is connected with a protective cover 6. The staff opens the protective cover 6 by turning it, and then inserts the high-pressure water gun into it. Connect to the end of the sewage collection pipe 5 close to the protective cover 6 to flush the inside of the sewage collection pipe 5, so that to a certain extent, it is convenient for the staff to clean up the sludge and impurities accumulated in the sewage collection pipe 5.

Referring to Fig. 2, the top inside of the connecting pipe 4 near the protective cover 6 is provided with a filter screen one 9, through which the sewage collected by the sewage collection pipe 5 into the connection pipe 4 is filtered. The drainage wells 1 are at a vertical angle, so as to avoid silt or sundries from entering the connecting pipe 4 to a certain extent and causing blockage inside the drainage pipe 3 .

With reference to Fig. 2, the material of glue 17 is polyurethane waterproof glue, replaces traditional glue by glue 17, thus avoid foam block 15 and filter screen 2 12 soaking in pipeline for a long time and cause foam block 15 and filter screen 2 12 as far as possible Disconnect between them, and avoid the foam block 15 from moving on the lower surface of the filter screen two 12 to a certain extent.

Referring to FIG. 2 , the drainage well 1 is provided with a limit ring 14 inside the upper end of the drain pipe 3 , and the foam block 15 is blocked by the limit ring 14 to prevent it from sliding down excessively.

With reference to Fig. 2, the upper surface of blocking plate 13 and the inner wall top of draw-in groove 10 are all provided with magnet 8, and two groups of magnets 8 opposite sides can attract each other, after the sludge on filter screen two 12 upper surfaces is cleaned, make blocking The plate 13 moves upwards, so that the two groups of magnets 8 are connected. At the same time, the stability of the blocking plate 13 is increased through the connection between the two groups of magnets 8, thereby avoiding the movement of the blocking plate 13 as much as possible. In addition, through the blocking plate 13 Block the end of the sewage collecting pipe 5 close to the drainage well 1, so as to prevent the sludge collected inside the sewage collecting pipe 5 from being poured back into the drainage well 1 as much as possible.

The implementation principle of the embodiment of the pipeline anti-blocking structure for municipal engineering water supply and drainage is as follows:

When there is too much sludge accumulated on the upper surface of the filter screen 12, the filter holes inside the filter screen 12 will be blocked, so that the sewage will stay on the upper end of the filter screen 12, and at the same time, foam will be caused due to the lack of water flow at the lower end of the filter screen 212. The buoyancy of the block 15 disappears, thereby driving the blocking plate 13, the slide block 18 and the filter screen two 12 to move downward. In addition, when the blocking plate 13 moves downward, the internal water flow of the drainage well 1 can flow to the The inside of the drainage pipe 3, so as to avoid as far as possible that the drainage well 1 is blocked and the sewage cannot be discharged.

The staff opens the protective cover 6 by turning, and then flushes the inside of the sewage collection pipe 5 by plugging the high-pressure water gun into the end of the sewage collection pipe 5 close to the protective cover 6, so that it is convenient for the staff to clean the sewage collection pipe 5 to a certain extent. Clean up the sludge and impurities accumulated in the interior, filter the sewage that is introduced into the connecting pipe 4 through the filter screen 19, and at the same time, pass through the vertical angle between the sewage collection pipe 5 and the drainage well 1, so that To a certain extent, try to avoid silt or sundries from entering the inside of the connecting pipe 4 to cause blockage inside the drain pipe 3 .
