Description

Technical Field

[0001] The utility model relates to a water level gauge for hydraulic surveying, belonging to the technical field of hydraulic engineering. Background Art

[0002] A water level meter is an instrument that automatically measures and records the water level of rivers, lakes, irrigation canals and other water bodies. According to the sensor principle, it can be divided into float type, tracking type, pressure type and reflection type. Among them, the acoustic wave water level meter uses the principle of sound wave reflection on different interfaces to measure the water level. Among them, the air-medium acoustic wave water level meter uses air as the propagation medium of sound waves. The transducer is placed above the water surface, and the sound waves are reflected by the water surface. The water level can be calculated and displayed according to the echo time.

[0003] The existing patent number is CN220508172U, which is a water level meter for hydraulic survey. This device is convenient for adjusting the angle of the ultrasonic level meter by setting an adjustment mechanism. There is no need to install the ultrasonic level meter in the direction of the liquid level, and it can be adjusted later, which improves the convenience of installation. By setting a lifting mechanism, when the liquid level rises, the height of the ultrasonic level meter can be adjusted, so as to avoid shortening the distance between the liquid level and the ultrasonic level meter, which causes the overlapping of the transmitted wave and the reflected wave of the ultrasonic level meter. However, when this device is used to measure the water level of the water surface, it is difficult to ensure the stability of the water surface, and it is easy to have ups and downs during the flow of water source, thereby reducing the water level detection effect; and when the water level changes, the position of the water shoreline will change. It is difficult to achieve the ideal adjustment effect by only manually adjusting the position, and it is difficult to automatically adjust the position of the water level meter according to the change of the water shoreline.
