Description
Technical Field
[0001] The present invention relates to the technical field of water level detection, and in particular to a high-precision portable water level detection device, a detection method, an electronic device and a computer-readable storage medium. Background Art
[0002] In the field of construction engineering, deep foundation pit engineering is a common sub-project of super high-rise buildings. In order to ensure the construction safety of deep foundation pits and provide necessary construction conditions for underground projects, the foundation pits need to be pumped and drained to make the groundwater level lower than the lowest elevation of the foundation pit. The groundwater level of deep foundation pits needs to be regularly monitored through observation wells. The water level is an important parameter for determining whether deep foundation pits need to start groundwater pumping. At present, the existing water level detection usually adopts liquid level meter or tape measure, sets up multiple pressure sensors in deep foundation pit to calculate water level by pressure value or uses ultrasonic wave for non-contact detection; The first type of liquid level meter is affected by various environmental factors on site and its own accuracy, resulting in low detection accuracy; The second method of using pressure value requires manual installation of multiple pressure sensors on the inner wall of deep foundation pit in the early stage, which is difficult to construct and has high labor cost, and the arrangement, location and number of pressure sensors will affect the water level detection accuracy; The third ultrasonic detection method uses the time difference between transmitting ultrasonic wave and receiving ultrasonic wave to calculate water level. Although non-contact detection is realized, in actual detection, the ultrasonic probe is not in an absolutely vertical state, which makes the ultrasonic signal unable to be absolutely perpendicular to the water surface. Due to the inclination angle problem between the ultrasonic signal and the water surface This results in low detection accuracy. To address this problem, in the prior art, an ultrasonic probe is usually set on a horizontal plate-type leveling structure, and lifting rods are set around the leveling structure. The angle of the ultrasonic probe is adjusted by moving the lifting rods up and down. This method requires a complex mechanical structure to drive the lifting and lowering of the lifting rods. The lifting distance is difficult to accurately control, and the detection accuracy depends on the adjustment fineness of the lifting rods. The accuracy is low, and the probe must be fixedly connected and vertically connected to the leveling device. When in use, the leveling device and the probe must be fixed above the water level to be measured. The portability is poor and the flexibility is low. In addition, due to the short lifting distance of the lifting rod, the adjustable angle is small, which is not suitable for leveling in cases with large inclinations. Therefore, it is necessary to design a high-precision portable water level detection device, a detection method, an electronic device and a computer-readable storage medium to solve the above technical problems.

When in use, it is not necessary to ensure that the leveling structure must be fixed and vertically set above the water level to be measured. According to the test needs, the operator can hold the detection device and make adaptive adjustments according to the angle corresponding to the direction or position of the detection device, which is highly flexible; the angle adjustment mechanism adopts a driving mode in which the roller is tangent to the outside of the spherical shell, and the inclination angle of the ultrasonic probe is detected in real time through an electronic level meter, and a control module is integrated.
