Description

Technical Field

[0001] The utility model belongs to the technical field of water retaining dams, and in particular relates to an adjustable water retaining dam. Background Art

[0002] A dam is a water-retaining structure that intercepts the flow of water in rivers and canals to raise the water level or regulate the flow. It is used for flood control, water supply, irrigation, hydroelectric power generation, improved navigation, etc. Commonly used water retaining dams include rubber dams, sluice gates and flap gate dams. The height of the water retaining dam determines the depth of the water storage. In actual use, the height of the water retaining dam needs to be adjusted to meet the water storage depth.

[0003] The following defects exist in the existing water retaining dam height adjustment: in order to achieve the height adjustment of the water retaining dam, the hydraulic pump used is installed in the river channel, which is soaked in water flow and buried in silt for a long time, and its service life is greatly shortened, and the stability during use cannot be guaranteed. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides an adjustable water retaining dam, and the technical solution adopted is as follows:

[0005] An adjustable water retaining dam includes side bases located on both sides of a river channel, a central base is provided in the middle of the river channel, a water retaining plate is provided on both sides of the central base, lifting grooves for placing lifting plates are provided inside the water retaining plate, the side base and the central base, and a mounting groove perpendicular to the lifting groove is also provided inside the side base and the central base; a hydraulic cylinder is installed inside the mounting groove, and an ear seat for connecting with the hydraulic cylinder is provided at a position corresponding to the mounting groove in the lifting plate.

[0006] Furthermore, a plurality of vertical reinforcing ribs are provided on the side of the lifting plate opposite to the ear seat, and slots are provided in the water retaining plate at positions corresponding to the reinforcing ribs on the side of the lifting plate, which can increase the strength of the lifting plate and prevent it from being easily bent and damaged under the pressure of the water flow.

[0007] Furthermore, the rear side surface of the water retaining plate is an inclined surface, and the bottom thickness of the water retaining plate is greater than the top thickness, thereby ensuring that the water retaining plate is stably placed in the river channel.

[0008] Furthermore, a protrusion is provided on the upper surface of the lifting plate and located inside the side base or the central base, and the ear seat is installed on one side of the protrusion above the lifting plate.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] The lifting plate of the utility model is adjustable. When the upstream water level in the river channel needs to be adjusted, the lifting plate in the water retaining plate can be raised under the support of the hydraulic cylinder. During the lifting and lowering process of the lifting plate, the side base and the central base can play a role of blocking and supporting the lifting plate, and a plurality of reinforcing ribs are provided on the side of the lifting plate facing the upstream of the river channel, which can prevent the lifting plate from tilting or being damaged under the water flow pressure.

[0011] The hydraulic cylinder of the utility model is arranged in the installation groove on the rear side of the side base and the central base, and the bottom of the installation groove is higher than the normal water level of the downstream. The water flow passing through the water baffle or the lifting plate will not flow from the lifting groove to the installation groove under the obstruction of the protrusion above the lifting plate. Therefore, it can prevent the hydraulic cylinder from being soaked by water flow or filled with sand and gravel, thereby extending the service life and stability of the hydraulic cylinder.
