Description

Technical Field

[0001] This utility model relates to the field of water monitoring technology, and in particular to an automatic flood early warning instrument for small watersheds. Background Technology

[0002] The automatic flood warning instrument for small watersheds is a device used to monitor and warn of floods in small watersheds. It uses multiple sensors to monitor relevant hydrological data in the small watershed in real time. Through water level sensors, it accurately measures changes in water level. The device analyzes and processes this data according to preset algorithms and thresholds. When the monitored data reaches or exceeds the set flood warning threshold, the instrument will automatically trigger the warning mechanism.

[0003] Sensors are exposed to the outdoor environment and are affected by factors such as severe weather, flood impacts, siltation, and biological adhesion. Debris carried by floods can impact the sensor, reducing its accuracy. Siltation can cover the water level sensor, affecting measurement accuracy. Biological adhesion to the sensor surface can also interfere with accurate data acquisition. Existing technologies protect the sensor from direct impacts by floods, debris, and external environmental factors by installing protective shells or covers. Metal grids are placed around the water level sensor to block larger debris. However, in actual use, after prolonged use, impurities will accumulate on the metal grid, requiring cleaning. But since the metal grid is welded to the device, cleaning becomes more difficult. Utility Model Content
