Hydraulically driven type adjustable weir

Abstract

The invention discloses a hydraulically driven type adjustable weir. The hydraulically driven type adjustable weir comprises two balancing weight protecting covers, a weir plate, two weir plate driving groove wheels, a rotating shaft, a shaft seat, a balancing weight, gravity driving wheels and steel wire ropes; the rotating shaft is mounted on the shaft seat, the two weir plate driving groove wheels are mounted at the two ends of the rotating shaft correspondingly, the bottom of the weir plate is fixedly connected with the rotating shaft, the two side edges of the weir plate are pressed on the two weir plate driving groove wheels correspondingly, one ends of the steel wire ropes are fixed to the weir plate driving groove wheels, the other ends of the steel wire ropes wind around the gravity driving wheels to be connected with the balancing weight; the two balancing weight protecting covers are arranged on the two sides of a river channel correspondingly; and the gravity driving wheelsare fixed to the upper parts of the inner walls of the balancing weight protecting covers. The hydraulically driven type adjustable weir adopts hydraulic automatic driving operation, extra power sources do not need to be provided, and after using, it can be ensured that the river channel or a pipe duct has sufficient water in the dry season, and waterlogging caused by river rising in the rainy season is avoided.

Description

technical field [0001] The invention relates to adjustable weir equipment in the field of flood control and storage, in particular to a hydraulically driven adjustable weir. Background technique [0002] When the rainy season comes, the water level in the city's flood control channels and pipes will continue to rise. During the heavy rain season, the river water will often rise and cause waterlogging. However, when the dry season comes, the water level in the river will decrease due to the long-term drought, and in severe cases, the water level in the river and irrigation canal will be dried up. [0003] In order to ensure that there is enough water in the river channel or canal during the dry season, and that there will be no waterlogging due to the rise of the river during the rainy season, this requires us to consider the use of a system that can be automatically opened and closed according to the water level when designing and constructing these water conservancy facilit...

AI Technical Summary

Problems solved by technology

[0006] However, most of the existing adjustable weirs are driven by motors, which not only consumes a lot of energy, but also requires manual control, resulting in a large workload for later maintenance

In addition, it is inconvenient to install in many environments due to the limitation of electricity consumption
