A device for maintaining dredging water conservancy gates that reduces the influence of gate slots

Abstract

The invention discloses a device for maintaining and dredging a water conservancy gate that reduces the influence of a gate slot, comprising a building body, a water channel with an upward opening is arranged on the top of the building body, a gate frame is fixedly arranged at the front end of the water channel, and left and right symmetrically arranged openings face the water channel on the inner wall of the gate frame frame. There is a fixed gate track on the end wall of the gate groove far away from the water channel, a gate is slidingly connected in the gate frame, the gate is dynamically connected to the bottom of the gate opening device, and an upper pull rope is fixed on the top surface of the gate symmetrically. , the end of the upper stay rope far away from the waterway bypasses the left and right symmetrical winding wheels and is fixedly connected to the top surface of the slider. The slider is located in the slider chute and is slidably connected with it. The dredging starting mechanism can automatically block the door slot of the corresponding height when the gate is opened, protect the door slot, and can dredge the gate in time.

Description

technical field [0001] The invention relates to the related technical field of water conservancy gates, in particular to a device for keeping and dredging water conservancy gates which reduces the influence of gate slots. Background technique [0002] The gate is used to close and open the control facility of the discharge (discharging) channel. An important part of hydraulic structures, it can be used to intercept water flow, control water level, regulate flow, discharge sediment and floating objects, etc. [0003] The discharge flow produces a low-pressure vortex at the gate slot, which affects the flood discharge capacity and promotes cavitation of the water flow. The gate slot is easy to be cavitated, and the discharge water contains more impurities. If it is not dredged in time, it will easily block the gate and reduce the flood discharge capacity. Contents of the invention [0004] Aiming at the deficiencies of the above-mentioned technologies, the present invention...

Problems solved by technology

[0003] The discharge water produces a low-pressure vortex at the gate slot, which affects the flood discharge capacity and promotes cavitation of the water flow. The gate slot is easy to be cavitated, and the discharge water contains more impurities. If it is not dredged in time, it will easily block the gate and reduce the flood discharge capacity.
