Flood prevention device

Abstract

The invention discloses a flood prevention device which is formed by splicing and combining a plurality of independent flood prevention units. Each flood prevention unit comprises a bottom plate, a support frame, a steel plate, an energy absorption sponge, buffer baffles and buffer stop strips, wherein the energy absorption sponge is paved on the steel plate, the buffer baffles are arranged on theinclined face, opposite to the bottom plate, of the steel plate at an interval, and the buffer stop strips are arranged on the horizontal plane opposite to the bottom plate; and the baffle stop strips are flexible, and each buffer stop strip comprises two carbon fiber meshes, two sponge strips and a plurality of sponge particles. The flood prevention device can effectively reduce the impact forceof water flow; the energy absorption sponges can further reduce the impact force, and especially after a previous flood peak wets the energy absorption sponges and when flood peak water flow coming again meets with the wetted energy absorption sponges, the impact force can be obviously reduced; besides, the weight of the energy absorption sponges is greatly increased, the water resistance of theflood prevention device is higher, and the bottom plates are not easy to move when the downward pressure borne by the bottom plates is increased; and during installation, the weight of the energy absorption sponges is low when water is not absorbed, and the flood prevention device is convenient to carry.

Description

technical field [0001] The invention relates to the technical field of flood control and water blocking, in particular to a flood control device. Background technique [0002] Due to the tidal changes of rivers or seawater in nature, especially the flood caused by heavy rain, and the change of river bed height, the water level is constantly changing. Once a spring tide or flood peak occurs, the water level will exceed the dam built on the river bank, which will cause great harm to people's life. big damage. Especially when the water flow of the flood peak reaches the embankment for the first time, the impact force of the water flow on the embankment is the greatest. Once there is a certain depth of water at the embankment, the force on the embankment will mainly come from the pressure of the water flow, and the impact force of the water flow will be weakened. If the dam can resist the impact of each flood peak, the probability of dam failure will be greatly reduced. Tradit...
