Mechanical movable retaining dam

Abstract

The invention discloses a mechanical movable retaining dam which comprises a dam foundation, a movable dam facing, a bottom rotating shaft, a foundation embedded fixing base, a worm wheel screw rod lifting machine, a pneumatic motor and an air compressor. The foundation embedded fixing base is installed on the dam foundation, the bottom rotating shaft is installed on the foundation embedded fixing base, the movable dam facing is fixedly connected with the bottom rotating shaft and can rotate around the bottom rotating shaft, one end of the worm wheel screw rod lifting machine is movably connected with the back side of the movable dam facing, the other end of the worm wheel screw rod lifting machine is movably connected with the foundation embedded fixing base, the worm wheel screw rod lifting machine is connected with the pneumatic motor, and the pneumatic motor is connected with the air compressor. The mechanical movable retaining dam is reasonable in structure, firm, reliable and capable of not being affected by floating sundries and not being limited by the width of a river. The pressure of the compressed air is converted to the rotating mechanical energy through the pneumatic motor to be used by the worm wheel screw rod lifting machine, the worm wheel screw rod lifting machine pushes the movable facing to lift, and the quality of the water cannot be polluted.

Description

technical field [0001] The invention relates to the field of water-retaining structures, and more specifically relates to a mechanical movable water-retaining dam. Background technique [0002] A dam is a water-retaining structure that intercepts the water flow of a river channel to raise the water level or regulate the flow. It is used for flood control, water supply, irrigation, hydropower generation, and improvement of shipping. Commonly used dams include rubber dams, sluice gates and flap gate dams. Rubber dams are widely used because they are close to the river bed without blocking water, simple in structure, large in span, good in seismic performance, beautiful in shape, and light in weight. , the rubber dam is made of rubber material, which has poor impact resistance, is easy to be scratched by sharp objects, the dam body is easy to burst, and the dam body lifting speed is too slow; although the sluice gate is strong and durable, its construction period is long and th...

Problems solved by technology

Commonly used dams include rubber dams, sluice gates and flap gate dams. Rubber dams are widely used because they are close to the river bed without blocking water, simple in structure, large in span, good in seismic performance, beautiful in shape, and light in weight. , the rubber dam is made of rubber material, which has poor impact resistance, is easy to be scratched by sharp objects, the dam body is easy to burst, and the dam body lifting speed is too slow; although the sluice gate is strong and durable, its construction period is long and the cost is high; the flap door Although the structure of the dam is simple and the construction period is short, it cannot withstand the impact of severe floods, causing it to fail to automatically flap and affect flood control safety. Normal water storage makes it impossible to clean up the floating objects, making the river channel dirty and affecting the landscape effect

Moreover, some dams use hydraulic systems to raise and lower the dam surface. Once the hydraulic oil leaks, it will pollute the water quality.
