Description

Technical Field

[0001] The utility model relates to the technical field of dam blocking plates, in particular to a flap gate capable of adjusting the water level height. Background Technique

[0002] With the acceleration of climate change and urbanization, the problems of floods and waterlogging are becoming increasingly serious. In order to effectively control floods and drain waterlogging, it is necessary to accurately adjust the water levels of water bodies such as rivers, lakes and reservoirs. The flap gate can automatically adjust the water level according to the flood situation to achieve the purpose of flood control and waterlogging drainage. Water resources are an important part of the ecosystem and play a crucial role in the stability of the ecological environment and the protection of biodiversity. In order to protect the ecological environment, it is necessary to reasonably adjust the water level of the water body to meet the survival and reproduction needs of aquatic organisms. The flap gate can automatically adjust the water level according to the requirements of the ecological environment to provide a suitable living environment for aquatic organisms. For example, when a flood comes, the flap gate can automatically rise to increase the flood discharge capacity of the river channel and prevent floods from overflowing; in the dry season, the flap gate can lower the water level to ensure agricultural irrigation and ecological water use.

[0003] However, during the use of the existing river blocking flap gate, due to the inability to control the scale of the released river water, when too much river water accumulates on the riverbed surface, it is necessary to lift the entire flap gate for release. However, during the release process, due to the influence of river water pressure and impact force, it is impossible to close the flap gate again during the release process, and it can only wait for the water flow to stabilize before closing the flap gate, thus unable to control the river water flow and the released water volume, resulting in the loss of water resources and the problem of waterlogging.

[0004] Therefore, we provide a flap gate capable of adjusting the water level height to solve the above problems. Content of the Utility Model

Moreover, a damping rubber belt 244 is provided at its connection to prevent damage to the flap gate 241 during the disassembly and installation processes. When a large amount of river water needs to be released, the hydraulic cylinder assembly 23 drives the front support adjustment assembly 22 to lift the flap gate 241 at an angle, releasing a large amount of river water. In this way, the usage process of a flap gate capable of adjusting the water level is completed.
