| titleOfInvention | Drainage pipeline grating device |
| abstract | The invention discloses a drainage pipeline grating device. The drainage pipeline grating device comprises a water body filtering area with a water inlet pipeline and a water outlet pipeline. A grating cylinder with the vertical axis is arranged in the water body filtering area. The grating cylinder is provided with a tangent inlet communicated with the water inlet pipeline and a grating net arranged on the peripheral wall of the grating cylinder. The grating cylinder serves as a filtering structure, and therefore the defect that impurities easily adhere to an existing straight-flow type filter screen is overcome; the tangent inlet is formed, a water body forms rotational flow in the grating cylinder, and therefore the water flow direction is parallel and tangent to the cylinder wall, the impurities can not adhere to screen holes of the cylinder wall, and the problems that the water filtering area is sharply narrowed due to impurity adhesion, flowing is not smooth, and water overflows out of the water inlet of the water inlet pipeline are solved. |
