Water retaining dam for water conservancy and hydropower engineering

Abstract

The utility model relates to the technical field of water conservancy and hydropower engineering, and discloses a water retaining dam for water conservancy and hydropower engineering, which comprises a dam body, a mounting frame fixedly mounted at the front end of the dam body, a filter screen fixedly mounted on the mounting frame, and a connecting frame fixedly mounted at the top end of the filter screen. Garbage floating on the dam is blocked through a filter screen, then a second driving motor is controlled to drive a second gear plate installed at the output end of the second driving motor to rotate, and due to the fact that the second gear plate and a first gear plate are meshed with each other, the garbage floating on the dam is blocked. Therefore, when a second gear block drives a first gear block to rotate, a first threaded rod can also rotate, and when the first threaded rod rotates, a fixing frame can be driven to move, so that a push plate at the bottom of the fixing frame pushes garbage filtered on a filter screen to one side; and therefore, a worker can more conveniently clean the garbage floating on the water surface.
