Description

Water conservancy project drainage device

Technical Field

The utility model relates to the technical field of drainage devices, in particular to a drainage device for a water conservancy project.

Background Art

Drainage projects refer to projects that collect and discharge human sewage, various wastewater from production, excess surface water and groundwater. The main facilities include drainage ditches or pipelines at all levels and their ancillary buildings. Depending on the different drainage objects and drainage requirements, water pumps or other water-lifting machinery, sewage treatment buildings, etc. can also be added.

In this regard, a Chinese utility model patent with a publication date of October 20, 2023 and a publication number of CN219863254U discloses a water conservancy engineering drainage device, which relates to the field of water conservancy engineering technology, including a filter box, the left side of which is fixedly connected to a drainage pipe, and the right side of which is fixedly connected to a water inlet pipe. In the above scheme, the rotating rod fixedly connected to the lower surface of the motor is rotated by the action of the motor, so that the connecting rod fixedly connected to the left side of the rotating rod is rotated, and the plate brush is rotated by the action of the connecting rod, and the inner cavity of the filter frame is cleaned by the action of the plate brush, thereby preventing the filter frame from being blocked when filtering impurities. When there are too many impurities, the upper surface of the filter box is opened by opening the sealing cover, and the rotating rod is moved upward by lifting the sealing cover upward, so that the filter frame moves upward under the action of the limiting circular plate, so that the staff can clean the impurities in the inner cavity of the filter frame.

In the above technical solution, the filter frame is cleaned from the inside to the outside, and some larger debris filtered out is distributed in the inner cavity of the filter frame. Such debris is difficult to be brushed away. At the same time, larger debris is easy to break the mesh during the brushing process, causing damage to the filter frame. In existing devices, most of them are cleaned by manually removing the filter plate in the device, and the filter assembly in the drainage device is difficult to clean automatically.
