[0002] A water conservancy project is a project built to eliminate water disasters and develop and utilize water resources. When a water conservancy project is completed, its water level needs to be monitored to avoid excessive water level differences between upstream and downstream, resulting in dam breaches and overpressure. After searching, the patent with application number 202320731377.9 discloses a water conservancy water level monitoring device, including a cylinder, and an anti-winding mechanism is set at the bottom of the cylinder. An interception net is set to intercept water plants to prevent the floating ball from winding and affecting the measurement results.
