Water retaining dam for water conservancy and hydropower engineering

The utility model relates to a water retaining dam for water conservancy and hydropower engineering, which comprises a dam body, a first groove is arranged on the dam body, a water retaining plate isarranged in the first groove, and the utility model belongs to the technical field of water retaining dams. A containing groove is formed in the top of the dam body, a rotating plate is arranged in the containing groove in a rotating mode, and a first driving piece used for driving the rotating plate to rotate is arranged in the dam body. An abutting part is arranged in the rotating plate in a sliding mode, and a second driving piece used for driving the abutting part to slide out of the rotating plate so as to abut against the water baffle is arranged on the rotating plate. By using the waterretaining dam, the probability that the water retaining plate is broken by pressing can be reduced. 本实用新型涉及一种用于水利水电工程的挡水坝，包括坝体，坝体上设置有第一凹槽，第一凹槽内设置有挡水板，属于挡水坝技术领域。所述坝体的顶部设置有容纳槽，所述容纳槽内转动设置有转板，所述坝体内设置有用于驱动转板转动的第一驱动件；所述转板内滑动设置有抵接部，
