Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy dams, in particular to a dam structure. Background Art

[0002] Flood control dams are an important part of urban development and construction. At the same time, the use of scientific and standardized dam construction methods and management systems is of great importance to the construction safety and quality of dam projects. When the flood control dam intercepts the water flow to a certain extent, it is necessary to use the drive component to extract the gate to open the drainage trough to relieve pressure and drain water. However, there will be a lot of floating objects on the water surface. When the pressure is relieved and the water is drained, the floating objects may be sucked into the drain outlet, causing the drain outlet to be blocked, which has a great impact on the drainage.

[0003] For example, Chinese patent publication number CN219840037U discloses a flood control and drainage structure for a dam, including a dam body and a drainage groove provided on the dam body, and also including a valve, which is arranged on the dam body and is used to block the drainage groove, a driving component, which is arranged in the dam body and is used to drive the valve to move and open; a push plate, which is arranged on the valve; when the drainage groove is blocked, the hydraulic push rod is started to drive the valve to move and close the drainage groove, and at the same time drive the hexagonal protrusion to insert into the hexagonal groove, and use the auxiliary component to drive the push plate to move along the inner wall of the drainage groove.

[0004] However, in the above scheme, although the device is convenient for cleaning the garbage in the gutter when in use, it is not convenient for intercepting the garbage in the water flow and preventing it from entering the gutter, which will still cause the gutter to be blocked, affecting the flood discharge efficiency and the convenience is not high.
