AI Technical Summary
Existing hydrological monitoring poles are prone to getting tangled with debris during long-term operation, which can obscure the scale lines, accelerate corrosion, and increase maintenance difficulty. Current cleaning methods are time-consuming and labor-intensive.
A hydrological monitoring and early warning rod was designed, which adopts a hollow water level rod, combined with an electric cylinder-driven lifting seat and blade structure to automatically cut away entangled debris, and uses an elastic diaphragm to prevent impurities from entering, ensuring that the scale is clearly visible.
It enables automatic removal of tangled debris, extends equipment life, reduces maintenance costs, and ensures the accuracy of water level monitoring data and the timeliness of early warnings.
