Description

Technical Field

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

[0002] A silt dam is a type of dam structure in water conservancy and hydropower projects. A silt dam can intercept the lost soil in the river channel in areas with severe soil erosion, thereby forming a silt landform, thereby expanding the area of ​​cultivated land and facilitating production and life. After the silt flows to one side of the silt dam for a period of time, the silt settles below the river channel, and the water flows through the irrigation culvert on the silt dam to the other side of the silt dam. When the water flows into the interior of the silt dam, the floating debris in the water will clog the interior of the silt dam, affecting the normal use of the silt dam.

[0003] After searching, a Chinese patent discloses a silt dam structure (authorization announcement number CN218712677U), including a silt dam body, the surface of the silt dam body is provided with a stacking structure, the stacking structure includes a long frame, the surface of the long frame is fixedly connected to the silt dam body, the inner wall of the long frame is fixedly installed with a filter screen, the surface of the long frame is fixedly connected to a baffle, the surface of the long frame is fixedly connected to a partition, the surface of the silt dam body is fixedly connected to a long plate, the surface of the long plate is slidably covered with a push plate, the surface of the push plate is slidably connected to the long frame, the surface of the push plate is fixedly connected to two connecting ropes, the surfaces of the two connecting ropes are both slidably covered with a stopper sleeve, the stopper sleeve is an elastic sleeve, and the surface of the stopper sleeve is fixedly connected to a positioning frame. Although this patented technology solves the disadvantage of the prior art that the debris on the filter screen of the silt dam is relatively scattered, making it difficult for staff to collect floating debris in the water.

[0004] However, the above device still has some shortcomings in actual use. The most obvious one is that when the water level in the silt dam rises to the height of the baffle, the debris around it will also float to the same height as the baffle. At this time, the push plate will push the debris floating on one side of the baffle to the other side during its movement, resulting in the filter being unable to filter the debris, which is then blocked inside the silt dam, affecting the normal use of the silt dam. In addition, workers need to pull the connecting rope by hand, but the resistance of the push plate is large, and it is very inconvenient to pull the connecting rope manually. Utility Model Content
