Description

Self-signal adjusting and protecting cofferdam wall in flood disaster flood season

Technical Field

The invention relates to the technical field of flood disaster prevention, in particular to a self-signal regulation protection cofferdam wall in a flood disaster flood period.

Background

Flood disasters include both flood disasters and rain disasters. Among them, the disasters caused by the increase of water volume in rivers, lakes and coastal waters, the flooding caused by water level rising and the torrential flood are called flood disasters due to strong rainfall, ice and snow melting, ice slush, dam burst, storm tide and the like; the large amount of accumulated water and runoff are generated due to heavy rain, heavy rain or over-concentrated long-term rainfall, and the drainage is not timely, so that the disasters caused by waterlogging and flooding of lands, houses and the like are called as waterlogging disasters. Flood disasters and rain flood disasters often occur in the same area simultaneously or continuously, are sometimes difficult to define accurately, and are often collectively called flood disasters.

According to chinese patent CN104878727B, the piston rod in the oil cylinder barrel is utilized to push the valve plate forward, lower the flood discharge, pull the valve plate to raise the water storage, and support the valve plate to bear the hydraulic load of the upstream face, so the operation is simple, the operation is stable, safe and reliable, no matter the oil cylinder or any control element of the pipeline is damaged, the valve plate will not be lowered, the operator needs to manually observe, and the effective driving adjustment is performed, the operator is in the dangerous position of flood disaster, the safety problem of the operator is easy to occur, and the regulation and control of the implemented equipment are affected.

According to Chinese patent, the drainage amount can be controlled according to different pressures of water in flood seasons, when the water amount reaches a certain amount, the movable plate can be pressed to move, the drainage hole is enabled to drain water, the more the water amount is, the more the pressure is, the more the drained water is, and when the water amount is less, the pressure is lower, the movable plate is pushed under the reaction of the spring to reduce the drainage amount, so that the drainage according to the water pressure is effectively realized, and the damage to an inclined wall is avoided. It is in long-time flood disaster, takes place the deposit of grit easily for it takes place to block, thereby makes water pressure not obtain the release, erodees the cofferdam wall, makes its whole emergence damage, is difficult to restrain the flood disaster.

In conclusion, the conventional cofferdam wall needs personnel to regulate and control in flood disasters, personnel safety cannot be guaranteed, and gravels can impact and block the cofferdam wall, so that the overall safety of the cofferdam wall is damaged.
