Description

Technical Field

[0001] The utility model relates to the technical field of separation, in particular to a roadbed drainage structure for municipal road construction. Background Art

[0002] Roadbed drainage is an important part of maintaining roadbed stability, and is designed to effectively collect and remove surface water and groundwater. In the construction of municipal roads, drainage measures are essential to deal with sewage and rainwater generated during construction. The current common roadbed drainage practice is to directly direct these water bodies into drainage ditches and rainwater wells. However, during construction, a large amount of sediment is often accompanied, which often flows into the drainage system along with sewage and rainwater, gradually accumulating in the drainage ditches and rainwater wells, forming a risk of blockage. In order to prevent the accumulation of debris and sediment in the drainage ditch, the existing practice often uses a filter net for preliminary filtration. However, over time, debris and sludge will gradually accumulate on the filter net, especially on one side of the net, and even block the filter holes, thereby weakening the filtration effect. Subsequent maintenance of the filter net, such as removing it from the drainage ditch for cleaning, is not only time-consuming, but also requires a lot of manpower. Utility Model Content

[0027] The movable rod 5 is connected to the rotating cylinder 11 through a first linkage mechanism. When the movable rod 5 moves up and down, it can drive the rotating cylinder 11 to rotate clockwise and counterclockwise.

[0028] A plurality of scrapers 16 are arranged on the upper surface of the second filter screen 10, and the scrapers 16 are connected to the rotating cylinder 11 through a second linkage mechanism. When the rotating cylinder 11 rotates clockwise and counterclockwise, it drives the plurality of scrapers 16 to move back and forth on the upper surface of the second filter screen 10 to scrape off the blockages adhering to the filter holes of the second filter screen 10.

[0029] In this embodiment, sewage enters the drainage well 3 from the circular floor drain 2 and passes through the first filter screen 4 and the second filter screen 10 for double filtration of impurities before being discharged. The debris accumulated on the first filter screen 4 is exposed to the outside and is therefore easier to clean, while the mud and fine debris entering the drainage well 3 are easily accumulated in the drainage well 3 and adhere to the filter holes of the second filter screen 10, thereby causing the drainage well 3 to be blocked. When the drainage well 3 is blocked, the movable rod 5 is driven downward by stepping on the pedal 6. When the movable rod 5 moves downward, the spring 15 is compressed by the second baffle 14. When the pedal 6 is stopped, the spring 15 is reset to drive the movable rod 5 to automatically move upward. The movable rod 5 is connected to the rotating cylinder 11 through the first linkage mechanism. When the movable rod 5 moves up and down, it can drive the rotating cylinder 11 to rotate clockwise and counterclockwise, thereby driving the lifting rod 12 to rotate in the drainage well 3, so as to clear the debris and silt blocked in the drainage well 3. In order to make water flow smoothly and avoid clogging of the drainage well 3, a plurality of scrapers 16 are arranged on the upper surface of the second filter screen 10, and the scrapers 16 are connected to the rotating cylinder 11 through a second linkage mechanism. When the rotating cylinder 11 rotates clockwise and counterclockwise, it will also drive the plurality of scrapers 16 to move back and forth on the upper surface of the second filter screen 10 to scrape and dredge the blockages adhering to the filter holes of the second filter screen 10, thereby avoiding clogging of the second filter screen 10 and achieving the purpose of smooth drainage in the drainage well 3.

[0032] As a further solution of the present invention, one end of the drainage pipe 9 extends to the inside of the drainage well 3 and is located below the second filter screen 10 , and the other end extends to the outside of the drainage box 1 .

[0033] In this embodiment, rainwater enters the drainage well 3 after being filtered by the first filter screen 4 , and enters the space below the second filter screen 10 after being filtered by the second filter screen 10 , and is then discharged to the outside through the drainage pipe 9 .

[0034] As a further solution of the utility model, a plurality of lifting rods 12 are arranged in a vertical array and are distributed at equal angles on the outer periphery of the rotating cylinder 11, and the surfaces of the lifting rods 12 are treated with a smooth transition.

[0035] In this embodiment, when the movable rod 5 moves up and down, it can drive the rotating cylinder 11 to rotate back and forth clockwise and counterclockwise, thereby driving the lifting rod 12 to rotate in the drainage well 3, thereby achieving the purpose of clearing the debris and silt blocking the drainage well 3, so that the water flows smoothly and avoids the problem of blockage in the drainage well 3.

The ball 25 is movably engaged in the spiral groove 24 and can roll in the track formed by the spiral groove 24 .

[0037] In this embodiment, when the movable rod 5 is inserted into the rotating cylinder 11 and moves up and down, it can drive the ball 25 to roll in the track formed by the spiral groove 24, thereby driving the rotating cylinder 11 to rotate.

[0038] As a further solution of the utility model, the second linkage mechanism includes an annular frame 17 fixed on the second filter screen 10 and a rotating ring 19 fixed on the rotating cylinder 11. A top cover 18 is fixed on the top of the annular frame 17. The rotating cylinder 11 is arranged through the top cover 18. The rotating ring 19 is movably clamped on the inner side of the annular frame 17. A plurality of arc grooves 20 are provided on the rotating ring 19 at equal angles. A clamping column 21 is movably clamped in the arc groove 20. A connecting rod 22 that is arranged through the annular frame 17 is fixed on the clamping column 21.

When the rotating cylinder 11 rotates reciprocatingly clockwise and counterclockwise, it will also simultaneously drive multiple scrapers 16 to reciprocate on the upper surface of the second filter screen 10, so as to scrape and clear the blockages adhering to the filter holes of the second filter screen 10, thereby avoiding blockage of the second filter screen 10.

[0040] As a further solution of the present invention, a soft rubber layer is fixedly adhered to the surface of the scraper 16 .

[0041] In this embodiment, damage to the surface of the second filter screen 10 caused by the scraper 16 when the scraper 16 moves on the surface of the second filter screen 10 is reduced.

[0042] The working principle of the utility model is as follows: after sewage enters the circular floor drain 2, it is discharged after being filtered by the first filter screen 4 and the second filter screen 10. The debris accumulated on the first filter screen 4 is easy to clean, while the mud and fine debris entering the drainage well 3 are easy to accumulate in the drainage well 3 and adhere to the filter holes of the second filter screen 10, thereby blocking the drainage well 3 and affecting the drainage. When the drainage well 3 is blocked, the movable rod 5 is driven to move up and down by stepping on the pedal 6. The movable rod 5 is connected to the rotating cylinder 11 through the first linkage mechanism. When the movable rod 5 is inserted into the rotating cylinder 11 and moves up and down, it can drive the ball 25 to roll in the track formed by the spiral groove 24, thereby driving the rotating cylinder 11 to rotate. When the movable rod 5 moves up and down, it can drive the rotating cylinder 11 to rotate clockwise and counterclockwise, thereby driving the lifting rod 12 to rotate in the drainage well 3 to clear the debris and silt blocked in the drainage well 3, so that the water flow passes smoothly and avoids the drainage well 3 from being blocked. A plurality of scrapers 16 are arranged on the upper surface of the second filter screen 10, and the scrapers 16 are connected to the rotating cylinder 11 through a second linkage mechanism. When the rotating cylinder 11 rotates clockwise and counterclockwise, the plurality of scrapers 16 are also driven to move back and forth on the upper surface of the second filter screen 10 to scrape and clear the blockages adhering to the filter holes of the second filter screen 10, thereby avoiding blockage of the second filter screen 10 and achieving the purpose of smooth drainage in the drainage well 3.
