Description

A dam gate for hydroelectric power generation

technical field

The utility model relates to the technical field of dam gates, in particular to a dam gate for hydropower generation.

Background technique

The dam gates of existing hydroelectric power generation mostly adopt the up and down opening and closing type, and the gate shape is rectangular. When the gate of this structural form is opened, the bottom of the gate will be subject to the pressure of the huge surge of water flow, causing the bottom of the gate to be easily deformed, so that the bottom deviates from the original position and is prone to water leakage.

The telescopic rod driving device is rotatably connected to the base, the base is set at the end of the gate frame away from the beam, the base is provided with a sealing groove matching the gate plate, and the inner wall of the sealing groove is provided with a sealing strip. A spring is arranged at the bottom of the sealing groove, and the other end of the spring is connected with a sealing pressing plate, and a sealing block is installed on the sealing pressing plate.

Preferably, the lifting device is a hoist.

Preferably, the telescopic rod driving device is a hydraulic motor, and the telescopic rod driving device is provided with a waterproof cover.

Preferably, the sealing block is made of rubber, has a certain degree of elasticity, and can be attached to the gate plate without gaps.

Compared with the prior art, the utility model has the beneficial effects that: when in use, the rubber sealing plate can be used as a buffer material, and the telescopic rod drive device can prevent long-term use, the impact of convection on the gate plate caused by displacement, and the sealing groove It can make the gate plate and the sealing block fit more perfectly, and prevent the overflow of water flow when the water is stopped. This utility model has simple structure, convenient operation, prolongs the service life of the gate, and improves the sealing performance of the gate.
