Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sensors, in particular to a high-stability leveling device for a water level detector. Background Art
[0002] Existing water level detection usually adopts a liquid level gauge, sets multiple pressure sensors in a deep foundation pit and calculates the water level using pressure values, or uses ultrasonic waves for non-contact detection. For the first type of liquid level gauge, the detection accuracy is low due to the influence of various on-site environmental factors and its own accuracy. For the second type using pressure values, multiple pressure sensors need to be manually installed on the inner wall of the deep foundation pit in advance, which has a large engineering construction difficulty and high labor cost, and the arrangement, setting position and quantity of the pressure sensors will all affect the water level detection accuracy. For the third type of ultrasonic detection method, the water level is calculated using the time difference between transmitting and receiving ultrasonic waves. Although non-contact detection is achieved, in actual detection, the ultrasonic probe is not in an absolutely vertical state, resulting in the ultrasonic signal not being perpendicular to the water surface absolutely. Due to the inclination angle between the ultrasonic signal and the water surface, the detection accuracy is low. To solve this problem, in the prior art, the ultrasonic probe is usually set on a horizontal plate-type leveling structure, and lifting rods are arranged around the leveling structure, and the angle of the ultrasonic probe is adjusted by the up and down movement of the lifting rods. This method requires a complex mechanical structure to drive the lifting of the lifting rods, and the lifting distance is difficult to accurately control. The detection accuracy depends on the adjustment fineness of the lifting rods, with low accuracy. Moreover, the probe must be fixedly connected and perpendicular to the leveling device, and the leveling device and the probe must be fixed above the water level to be measured during use, with poor portability and low flexibility. Since the lifting distance of the lifting rods is short, the adjustable angle is small, and it is not suitable for leveling in cases with a large inclination. In addition, the internal of the water level leveling device usually uses fixed rods combined with screws and other fixing methods to install the adjustment structure, and its stability depends on the connection tightness between the fixing parts and mechanisms such as screws. As the use time increases, the connection firmness between the fixing parts and the screws will become loose, resulting in a reduction in the stability of the entire leveling device. And because the ultrasonic probe is fixed on the leveling structure by the above installation method, it cannot be replaced, and the ultrasonic probe cannot be protected when not in use.
