Description

Technical Field

[0001] The utility model relates to the technical field of bridge flood prevention, in particular to a water conservancy bridge flood prevention device. Background Art

[0002] Bridges are one of the indispensable construction facilities in water conservancy projects. However, floods often occur in rainy areas. When floods occur, the impact of water flow on bridge piers is much greater than usual, which greatly increases the damage to the piers. In addition, large debris such as washed away stones and broken trees in the water flow will often hit the bridge piers, further affecting the service life of the bridge piers.

[0003] In Chinese utility model CN218911100U, a hydraulic bridge flood protection device is disclosed. The hydraulic bridge flood protection device is provided with a collar, a buffer device and a buffer plate. After the water flow hits the buffer plate, the buffer plate compresses the damper and the spring to reduce the impact force. At the same time, the water flow and debris drive the collar to rotate after hitting the vertical plate, which can also consume part of the impact force, avoiding the situation where the water flow and large debris directly hit the bridge pier and thus reduce the service life of the bridge. The spliced ​​fixed frame and collar are more convenient to install and disassemble. However, the hydraulic bridge flood protection device still has the following problems in use:

[0004] There are gaps between the buffer plates of the flood protection device of the water conservancy bridge, which makes it easy for impurities such as stones and branches in the flood to rush into the gaps between the buffer plates, resulting in the compression of the buffer plates being blocked, affecting the buffer effect and the service life.
