Abstract

A portable ultrasonic open channel water level automatic tracking and flow measuring device is made of European standard aluminum profiles, a liquid level ultrasonic sensor is installed at the top endof the device to measure the water level height of an open channel, a double-axis linear guide rail mechanical aluminum profile is arranged in a guide rail, and a supporting rod is fixedly connectedwith the guide rail through a fixing base plate. A sliding block and a screw rod are mounted on the built-in double-axis linear guide rail; the sliding block is connected with a steering engine, the sliding block and the steering engine are driven by a stepping motor arranged on the lead screw to slide up and down on the lead screw, the steering engine is connected with a measuring rod and controls the rotation angle of the measuring rod, and ultrasonic probes are installed at the two ends of the measuring rod to conduct 360-degree vertical plane rotation measurement. The device is simple in structure, convenient to carry and high in measurement precision, is widely applied to flow measurement of open channels, and has important practical significance for water conservation of irrigation areas.

Description

technical field [0001] The invention relates to an open channel ultrasonic flow measuring device, in particular to an open channel ultrasonic flow measuring device based on the ultrasonic time difference method. Background technique [0002] Existing technology: a utility model patent for an "ultrasonic radar flow measurement system" disclosed by the publication number CN206515468U, including a central station and a radar station for wireless communication with the central station. The radar station includes a monitoring room, a radar bracket, a radar probe, and a monitoring room It is equipped with an acquisition controller, a power supply connected to it, and a wireless transmission module. The radar bracket is set above the monitored water body. Multiple radar probes are fixed on the radar bracket and emit ultrasonic waves to the water surface of the upstream water body. Each radar probe is connected to the water body. The acquisition controller in the monitoring room is ...
