The invention discloses an automatic
water intake device for ecological flow. The automatic
water intake device for the ecological flow comprises a water conveying
pipe buried in a dam and a buoyancybox floating on the water. The automatic
water intake device for the ecological flow is characterized by further comprising a first bent
pipe, wherein one end of the first bent
pipe is connected withthe water conveying pipe, the other end of the first bent pipe is provided with a water inlet pipe through a connection component, the water inlet pipe can rotate around the
horizontal axis perpendicular to the
water flow direction, the lower end of the water inlet pipe is connected with the connection component, the upper end of the water inlet pipe is provided with a
grating cover allowing waterinflow, a flow guide plate is arranged in the
grating cover and always keeps horizontal when the water inlet pipe rotates, and the flow guide plate is connected with the
buoyancy box through a connection chain. According to the automatic water intake device for the ecological flow, due to the action of the connection chain at the upper end of the flow guide plate, the flow guide plate always keeps horizontal when rotating around a shaft lever, so that the water inflow section formed between the water inlet pipe and the flow guide plate can be adjusted; when the
water level rises, the flow speed for the
water flow to enter the water conveying pipe is increased, when the
water level falls, the flow speed for the
water flow to enter the water conveying pipe is reduced, when the
water level rises, the water inflow section is reduced, when the water level falls, the water inflow section is increased, and the flow guide plate controls the water intake flow under various water levels.
