Drainage device for water conservancy project

Abstract

The invention aims to provide a drainage device for a water conservancy project. The drainage device comprises a drainage channel and a diversion channel communicating with the drainage channel. The drainage channel is provided with a water inlet and a water outlet. The diversion channel is located between the water inlet and the water outlet. A flow limiting gate is arranged at the position, between the diversion channel and the water outlet, of the drainage channel. The flow limiting gate moves in the vertical direction and can enter the drainage channel to limit part of water flow to pass through the water outlet. The diversion channel is provided with a diversion outlet. The connecting position of the drainage channel and the diversion channel is rotationally connected with a diversiondoor capable of closing a connecting port between the drainage channel and the diversion channel. The drainage channel is provided with a drive mechanism controlling the flow limiting gate to move upand down, and the drive mechanism drives the diversion door to rotate at the same time. According to the drainage device, when the flow of water passing through the drainage channel is too large, water passing through the drainage channel is guided to the diversion channel and drained out, and the situation that all water flow flows to branches from the drainage channel, and consequently the branches are overloaded and break a dike is avoided.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering equipment, in particular to a drainage device for water conservancy engineering. Background technique [0002] The water conservancy drainage device is a kind of equipment that controls the flow direction of the water flow according to the user's needs. The user uses the water conservancy drainage device to divert the water flow to other directions to make full use of the existing hydraulic resources. It has certain beneficial effects. [0003] In the prior art, the Chinese patent document with the authorized notification number CN110820674A discloses a drainage device for water conservancy engineering, including a casing, a pipeline and a lifting assembly. The uppermost end of the casing is provided with an upper hole, and the lowermost end of the casing is provided with a lower hole. Installed at the lower end of the lower hole of the shell, the lifting assembly includes a...
