[0002] With the advancement of technology, especially the rapid development of sensor and automation technologies, people have begun to explore the application of high-precision sensors and automation techniques in measuring water surface evaporation. However, existing water surface evaporation measurement devices still have some problems. For example, some ultrasonic-based measurement devices have shortcomings in measurement accuracy, environmental adaptability, and sensor protection. Especially in sub-zero temperature environments, the measurement accuracy of ultrasonic sensors is affected; and under conditions of water shortage in the evaporation dish, the sensor is easily damaged.

[0010] In a further embodiment, a cylindrical hole is provided at the end of the telescopic part of the telescopic push rod away from the fixed part.

[0011] In a further embodiment, the photoelectric liquid level sensor is horizontally connected to a cylindrical orifice via a pulley, and the photoelectric liquid level sensor can move in the vertical direction.

[0012] The technical effects and advantages of this utility model are as follows:

[0030] Working principle:

[0031] This high-precision telescopic water surface evaporation measuring device, after water is injected, connects the measuring cylinder 8 and the evaporation pool 9 through the rigid connecting pipe 10, ensuring a consistent water level. Pressing the control button 2 activates the motor 11c, which drives the telescopic push rod 11, which in turn lowers the photoelectric liquid level sensor 7 via the pulley 5. When the photoelectric liquid level sensor 7 contacts the water surface, its internal electrical signal changes and is fed back to the main controller 3. The main controller 3 then stops the motor 11c. At this time, the display screen 4 shows the current water level data. Simultaneously, the float 12a inside the measuring cylinder 8 changes with the water level, driving the displacement sensor 12c via the connecting rod 12b to generate an electrical signal that is transmitted to the main controller 3. The main controller 3 integrates the measurement data from different times, calculates the difference between the two water level measurements, and thus obtains the water surface evaporation rate, displaying the result on the display screen 4.
