Figure 1-4As shown, the water level observation device for hydrological monitoring includes: a counterweight frame 1 installed on the river bank; a support rod 2, the support rod 2 is fixed on one side of the counterweight frame 1; an isolation cylinder 3, the isolation cylinder 3 is rotatably installed on the support rod 2 and is located in the river, and water inlets are provided on both sides of the isolation cylinder 3, and isolation nets 4 are installed in the two water inlets; a float 5, the float 5 is placed in the isolation cylinder 3, and the float 5 is used to reflect the water level; a top plate 6, the top plate 6 is installed on the top of the float 5; an infrared rangefinder 8, the infrared rangefinder 8 is installed on the top inner wall of the isolation cylinder 3, and the emission port of the infrared rangefinder 8 is located directly above the top plate 6; a cleaning component, the cleaning component is arranged on the isolation cylinder 3, and the cleaning component is used to clean the isolation net 4.
[0023] In this embodiment, the counterweight frame 1 is installed on the river bank to provide stable support for the entire device, ensuring that the device is stable and not easily washed away or displaced by the water flow. The support rod 2 provides vertical support for the isolation cylinder 3, so that it can be stably located in the river. The isolation cylinder 3 is located in the river and cooperates with the water inlet and isolation net 4 to prevent large floating objects from entering the interior of the isolation cylinder 3, while allowing water to pass through, so that the float 5 can rise and fall with changes in water level. The rotation design of the isolation cylinder 3 helps to adjust the direction as needed to reduce water flow resistance. The float 5 moves up and down with the rise and fall of the water level, intuitively reflecting the current water level situation. The top plate 6 serves as the measurement target of the infrared rangefinder 8. The water level information is accurately obtained by measuring the distance between the top plate 6 and the infrared rangefinder 8. The infrared rangefinder 8 can measure the distance between the top plate 6 and the infrared rangefinder 8 non-contact, thereby accurately obtaining water level data and avoiding the influence of human errors in traditional observation methods.
[0024] In a further preferred embodiment of the present invention, the cleaning assembly includes a cleaning ring 14, two connecting ropes 15, two extension plates 16 and two adjusting parts. The cleaning ring 14 is movably mounted outside the isolation tube 3. The two connecting ropes 15 are fixed on the top of the cleaning ring 14. The two extension plates 16 are respectively fixed on both sides of the isolation tube 3. The two adjusting parts are respectively installed on the top of the two extension plates 16 and are respectively connected to the two connecting ropes 15. The adjusting parts are used to adjust the extension length of the connecting rope 15.
[0025] In this embodiment, by moving the cleaning ring 14, floating objects attached to the isolation net 4 can be scraped or brushed off, keeping the isolation net 4 clean and unobstructed. The up and down movement of the cleaning ring 14 can be conveniently controlled by the connecting rope 15 to achieve cleaning of the isolation net 4. The extension plate 16 provides space for installing an adjusting member, so that the adjusting member can be stably fixed on the isolation cylinder 3 and the extended length of the connecting rope 15 can be conveniently adjusted. When the isolation net 4 needs to be cleaned, the extended length of the connecting rope 15 can be adjusted by the adjusting member to move the cleaning ring 14 to the position that needs to be cleaned, and then the cleaning ring 14 can be released to move it up and down to scrape or brush off floating objects on the isolation net 4. This design not only improves the cleaning efficiency, but also reduces the labor intensity of manual cleaning, thereby ensuring the long-term stable operation of the water level observation device.
