Description

Technical Field

[0001] The utility model relates to the technical field of drainage devices, and more specifically to a new type of drainage device for water conservancy construction. Background Art

[0003] At present, during the construction of water conservancy projects, it is necessary to use a drainage device to drain the construction area. However, the drainage device occupies a large space, making it inconvenient to carry and reducing its flexibility of use. In addition, during the use of the drainage device, the surface of the filter screen needs to be cleaned to filter impurities. When too many impurities are cleaned, the export filter box needs to be lowered, which brings great inconvenience to use.

[0004] For example, announcement No. CN216223325U discloses a new type of drainage device for water conservancy construction, which includes a support seat, a protective cover is arranged above the support seat, a water pump is fixedly arranged inside the protective cover, a filter box is arranged on the left side of the protective cover, the filter box is arranged with a coarse-effect filter screen and a medium-effect filter screen, and brushes are arranged on the left sides of the coarse-effect filter screen and the medium-effect filter screen.

[0005] It can be seen from the above-mentioned public scheme that the drainage device is assembled from components such as a support base, a water pump, a filter box and a sedimentation box. It occupies a large space and is not easy to carry and move, which reduces the flexibility of the drainage device. In addition, during use, it is necessary to use a brush to clean the impurities and debris intercepted on the surface of the coarse-effect filter net and the medium-effect filter net, and the cleaned filtered impurities are stored in the filter box and need to be cleared out in time, which brings great inconvenience to use.
