Description

Technical Field

[0001] The present invention relates to a real-time monitoring and analysis device and method for the water flow at the outlet of an inverted siphon, belonging to the technical field of water conservancy projects. Background Technique

[0002] In water conservancy projects, an acoustic Doppler current profiler (ADCP) is a device that measures the water flow velocity in water bodies through sound waves. It utilizes the Doppler effect, emits sound waves, and receives the signals reflected from suspended particles or the water body itself in the water body, thereby calculating the distribution of the flow velocity. By integrating the flow velocity data at different depths, the flow rate of the inverted siphon can also be calculated. The ADCP has the following advantages: ① It has a fast measurement speed and can perform quasi-synchronous cross-section measurements; ② The ADCP uses sound waves as sensors, which is not only convenient and fast to operate, but also does not interfere with the water flow during measurement. It can directly measure the flow velocity cross-section and is suitable for various environmental measurements. The investment and use of this instrument can reduce the intensity of manual flow measurement and increase the safety of flow measurement personnel, with advantages such as high measurement accuracy, fast speed, high efficiency, time-saving, and labor-saving; ③ In the traditional measurement method, the measured water depth is restricted by the conditions of the instrument and equipment, and the maximum range is limited. However, the ADCP method can measure the cross-section depth range up to 180 m, and the flow velocity range is 0 to ±20 m / s, with a wider applicable range. The flow velocity in the channel is relatively large, the water quality is concerned, and it is not convenient to arrange boats or personnel to enter the water. At the same time, the water depth and channel width in the lock chamber, transition section, and channel change significantly. The existing technology measures comprehensive data such as flow rate and flow velocity by manually pulling the ADCP device, and the flow rate in the lock chamber section cannot be measured. At the same time, there is a lack of equipment for monitoring the water conditions at the outlet. Summary of the Invention

[0011] Further, the turntable is internally provided with a stepping motor and realizes continuous rotation from 0° to 360° through gear transmission.

[0012] Further, the ADCP device interacts with the total water diversion system in real time through a wireless communication module.
