River dam water retaining gate

Abstract

The invention discloses a river dam water retaining gate, and belongs to the technical field of gates. The river dam water retaining gate comprises a gate frame, a driving part, a gate plate, a linkage structure, a smashing structure, a water level sensor and a limiting structure, the gate plate is arranged in the gate frame and can move up and down in the gate frame, the gate plate moves downwards to be closed in the state of making contact with the bottom end in the gate frame, and water flows are prevented from passing through the gate frame. The gate plate moves upwards to be separated from the bottom end in the gate frame to be opened, the water flows pass through the gate frame, the driving part is arranged at the upper end of the gate frame, the driving part is used for driving thegate plate to move vertically in the gate frame, sliding grooves are formed in the front inner side wall and the rear inner side wall of the gate frame, and the smashing structure slides in the sliding grooves and is located on the right side of the gate plate. The smashing structure is used for smashing large blockages intercepted on the right side of the gate frame, the effect that a water outlet is not prone to being blocked by the blockages can be achieved, and the flood discharge efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of gates, and more specifically, relates to a dam water retaining gate. Background technique [0002] The gate is a control facility for closing and opening 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] Among the current water conservancy engineering facilities, the construction of barrages is a very popular water conservancy construction, in which gates are widely used to control the amount of water. The gates include up and down lifts, and its opening and closing are completed by electric machinery. Through the opening and closing of the gates, the circulation and interception of upstream and downstream river water are realized, so as to achieve the purpose of river water storage and flood discharge. [0004] Because the river often carries g...

Problems solved by technology

[0004] Because the river often carries garbage on the water, when the gate is opened, the garbage flows downstream along the water. When the garbage volume is large, it is easy t
