Description

[Detailed description of the invention] This invention is a dust removal method that removes drainage obstructions such as mud and gravel that flow into drainage basins such as both water basins and sewage basins, and reduces the need for internal cleaning work such as drainage ditches. It is related to the device.

That is, this invention consists of a cylindrical body having a collar on the upper edge that engages with the mouth edge of the drainage basin, and a bottom plate that is detachably attached to the lower part of the cylindrical body and has an overflow tube in the center. An embodiment of the dust removal device for a drainage basin will be described below based on the drawings.

The drawing shows a longitudinal sectional view of the embodiment, where 1 is a known concrete drainage basin and 2 is a drainage basin cover.

3 is a cylindrical body provided with an overflow hole 4 in the upper part and a flange 5 on the upper edge that engages with the mouth edge of the drainage basin 1; 6 is detachably attached to the lower part of the cylindrical body 3; and a bottom plate having a water overflow pipe 7 in the center, 8 a net basket detachably attached to the lower part of the cylindrical main body 3;
Reference numeral 1 denotes a rod-shaped handle provided on the cylindrical main body 3. In this embodiment, stop pins 9 that protrude inwardly and outwardly are provided at opposing positions at the bottom of the cylindrical main body, and the stop pins are provided on the bottom plate 6 and the net basket 8. An L-shaped groove 10 that engages with the bottom plate 9 is provided so that the bottom plate 6 and the mesh basket 8 can be attached to and detached from the cylindrical main body 3, respectively.

With the structure described above, when rainwater or sewage flows into the drainage basin 1 from the drainage hole provided in the lid 2, gravel or heavy water flows into the area A surrounded by the overflow tube 7, the cylindrical body 1, and the bottom plate 6. After the garbage has been removed, the water that overflowed the overflow tube and light garbage flow into the net basket 8.
Fine dust and water that have passed through the net basket 8 flow into a drain pipe 12.

The accumulated earth and sand can be drained by holding the handle 11 and lifting it up to empty the earth and sand.

Since it can be disassembled, it is extremely easy to clean the inside, and regular mud removal work can be carried out quickly.The simple structure makes it suitable as a dust removal device for drainage basins. be.
