Multipurpose rotary steel dam gate

Abstract

The invention discloses a multipurpose rotary steel dam gate, which belongs to the technical field of gates, and comprises a base, a gate, a blocking and rotating mechanism arranged in the base and used for water flow, and a steering drive arranged in the base and used for the gate, and the rotating mechanism comprises a height adjusting part, a driving butt joint part, a rotating rod, a fixed rotating block, a limiting block and a limiting groove. According to the multi-purpose rotary steel dam gate, through the use of the rotary mechanism, the gate can be effectively made to do fan-shaped motion so as to achieve the purpose of controlling the water level, and the multi-purpose rotary steel dam gate is simple in structure, reliable in performance, capable of storing water through the vertical gate and discharging flood through the horizontal gate, capable of solving the contradiction between flood control and water storage of urban river channels, beneficial to ecological environment protection and multi-direction use and suitable for popularization and application. Through the supporting mechanism, the gate can have a supporting effect when the horizontal door overflows, the acting force of the gate cannot directly act on the rotating mechanism, people can walk on the gate, and the effect of the gate is wider and more flexible.

Description

technical field [0001] The invention belongs to the technical field of gates, in particular to a multipurpose rotary steel dam gate. Background technique [0002] Steel dam gates are used to close and open the control facilities of the discharge (discharging) channel, an important part of hydraulic structures, which can be used to intercept water flow, control water level, adjust flow, discharge sediment and floating objects, etc. Steel dam gates are generally It consists of three parts: movable part, embedded part and opening and closing machinery. The steel dam gate is installed on the openings of overflow dams, bank spillways, scuppers, hydraulic tunnels and sluices to regulate flow. It is an important part of hydraulic structures to control upstream and downstream water levels, vent floods, and remove sediment or floating objects. It is a novel, beautiful and practical gate type with simple structure and reliable performance. , collapse the dam to discharge the flood, a...

Problems solved by technology

[0003] The existing gates of steel dams are designed according to the conventional design. The crank arm mechanism is connected with the hydraulic hoist cylinders in the hoist gate chambers at both ends of the dam, so as to drive the bottom shaft to rotate to realize the opening or closing of the gates. However, this This hydraulic transmission method has many defects: it is prone to leakage and pollutes the environment, especially when the hydraulic oil pipe is buried at the bottom of the gate, it will leak and pollute water resources; the observability is poor; the crank mechanism at both ends relies on electrical deviation correction, and the synchronization performance is poor ;The locking mechanism needs to set several points to lock the crank arm mechanism; installation and maintenance are inconvenient, and the operation is complicated. At the same time, the existing steel dam gate is only used for raising the dam and storing water. corresponding use in the environment
