Water conservancy channel gate

The utility model relates to the technical field of channel gates, in particular to a water conservancy channel gate which comprises a channel gate frame, adjusting grooves are formed in the two sides of the channel gate frame, lifting adjusting mechanisms are arranged in the two adjusting grooves, and folding gate mechanisms are installed at the bottom ends of the adjusting grooves. Water level sensors are fixedly installed in the middle and at the top of one side of the channel gate frame, an alarm is fixedly connected to the top of the channel gate frame, when flood discharge is conducted on a high water level, a lead screw is driven to rotate through rotation of a driving motor, the horizontal height of the channel gate is conveniently adjusted, and when the channel gate is controlled to be closed, the alarm is fixed to the top of the channel gate frame. And the two servo motors rotate to drive the rotating frame to adjust and rotate, so that the channel gate is conveniently driven to adjust to discharge
