Problems solved by technology

There are many problems in the flap gate dam, mainly including: first, water blocking, unable to withstand the impact of severe floods
The second is that it is easy to be jammed by floating objects or silted up by upstream mud and sand, resulting in the inability to turn over automatically and affecting flood control safety.
The third is that after the flood, the flap door was stuck by foreign objects when it was closed again, causing a large amount of water leakage

Embodiment Construction

[0023] see figure 1 and Figure 5 , the movable dam surface 1 is set, and the movable dam surface 1 is hinged on the fixed support 2 through the hinge shaft 9 at its bottom, and the length can be adjusted on the backwater side of the movable dam surface 1 to form a " The hydraulic cylinder 7 supported by the "people" character, the height of the movable dam surface 1 can be adjusted by adjusting the elongation of the hydraulic cylinder 7. include adjustments such as figure 1 The movable dam surface 1 shown is at the highest position, as figure 2 The movable dam surface 1 shown is at the position of two-thirds of the height, and image 3 The movable dam surface 1 shown is fully brought down, close to the river bed without blocking water.

[0024] In the specific implementation, the corresponding structural settings are also included in:

[0025] The hydraulic cylinders 7 as the support mechanism need to be arranged in a row at intervals along the axial direction of the hi...

Abstract

The hydraulic dam is characterized in that a movable dam surface is set. The movable dam surface is hinged on the fixed support with its bottom edge through the hinge shaft. man" supported hydraulic cylinders. The invention has the advantages of low cost, good safety, high reliability, no water blocking, durability, and can automatically release the dam to discharge floods like a flap gate dam.

Description

Technical field: [0001] The invention relates to a dam structure in water conservancy facilities, in particular to a lifting dam. Background technique: [0002] In order to store water on the river without affecting the safety of flood control, rubber dams that can be raised and lowered are widely used all over the world. However, the rubber dam not only has high cost, but also has poor safety and reliability and short service life. [0003] In addition to rubber dams, traditional movable dams also include water locks and flap gate dams. Barriers are the most costly and have a long construction period. There are many problems in the flap gate dam, mainly including: first, it blocks water and cannot withstand the impact of a catastrophic flood. The second is that it is easy to be jammed by floating objects or silted up by upstream mud and sand, resulting in failure to automatically turn over the board and affecting flood control safety. The third is that after the flood, ...
