Rubber dam self-collapsing protection method and device and device usage method

Abstract

The invention relates to a rubber dam self-collapsing protecting method and device and a device using method. According to the rubber dam self-collapsing protecting method, automatic drainage and dam collapse of a rubber dam, namely, a rubber dam bag in a water-filled state are controlled through a lever system. The rubber dam self-collapsing protecting device is mainly composed of water inlet pipe, the lever system, a bottom shaft rotation valve, a drain pipe and the rubber dam bag which are sequentially connected; one end of a transverse straight rod of the lever system is provided with a water collecting tank communicated with the water inlet pipe, and the other end of the transverse straight rod of the lever system is provided with a pulling straight rod which can open the bottom shaft rotation valve; when the water level is higher than the water inlet end of the water inlet pipe, water enters the water collecting tank, the water collecting tank sinks, therefore, the lever system loses balance and drives the pulling straight rod to move upwards, then the bottom shaft rotation valve is opened, and automatic dam collapse of the rubber dam is achieved. The rubber dam self-collapsing protecting method and device and the device using method have the advantages that the automatic dam collapse of the rubber dam can be achieved through a hydraulic and automatic mode, therefore, accidents caused by the fact that the dam cannot be collapsed in time can be effectively avoided, and life safety and property safety of people can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of rubber dams, in particular to a rubber dam self-collapsing protection method, a device and a method for using the device. Background technique [0002] With the development of polymer synthetic materials, rubber dams have been widely used in water conservancy. Due to its adjustable dam height, small flood discharge and water resistance, large discharge capacity, dam crest overflow, small dam height, convenient management, short construction period, and low investment, rubber dams are widely used in water storage, power generation, and irrigation. , water supply and groundwater recharge requirements, rubber dams are also especially suitable for urban water environment projects. Therefore, the rubber dam has become a very common low-head river-blocking structure in China. In recent years, the rubber dams that have been built in my country have played an active role in regulating and storing water resources...

Problems solved by technology

For poorly managed or unattended medium and small rubber dam projects, when encountering sudden floods, it is very easy to cause rubber dam project safety accidents and upstream flooding losses due to failure to drain the dam in time
