Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the present invention provides a flood discharge device for reservoirs. The purpose is to solve the existing flood discharge devices for reservoirs. The gate can flexibly adjust the water level only by means of power supply, driving device and detection equipment. Repeatedly inspect and monitor the water level, and adjust the opening and closing of the gate according to the water level, which is a waste of labor

Abstract

The invention relates to a flood discharge device for a reservoir, comprising a dam, a first gate, a connecting rod, a transmission device and a movable gate. The dam is arranged at the outlet of the reservoir and connects the mountains at both ends of the reservoir. The lower part of the dam is provided with drainage holes, the dam body is provided with a first wear-resistant ring, and the upper part of the first gate is fixed with a connecting rod. The transmission device includes a worm wheel, a worm, a housing and a hand wheel. The upper part of the body is provided with a flood discharge hole, and the stepped surface in the flood discharge hole is hinged with a movable gate. The movable gate is hinged on the hinge shaft. For the flood discharge device of the reservoir, the gate can flexibly adjust the water level with the help of power supply, driving device and detection equipment. Using manpower to open and close the gate to adjust the water level requires repeated inspections and monitoring of the water level, and the opening and closing of the gate is adjusted according to the water level, which is a waste of labor. .

Description

technical field [0001] The invention relates to the field of water conservancy engineering, in particular to a reservoir flood discharge device. Background technique [0002] Reservoirs are water conservancy engineering buildings that hold back flood water and regulate water flow, and can be used for irrigation, power generation, flood control and fish farming; it refers to artificial lakes formed by building barrages at the narrow mouths of ravines or rivers. It plays the role of flood control, water storage and irrigation, water supply, power generation, fish farming, etc.; due to continuous heavy rainfall, the water level of the reservoir is exceeded. Drainage of the downstream flood discharge area. [0003] The existing flood discharge device of the reservoir is to build a dam at the outlet of the reservoir, and a gate is installed in the dam. The gate can adjust the water level flexibly with the help of power supply, driving device and testing equipment. The driving eq...
