Abstract

The invention provides an underwater verticality adjusting device for an ADCP (Acoustic Doppler Current Profiler) sensor. The underwater verticality adjusting device for an ADCP sensor comprises an inner ring assembly, an outer ring assembly, a cantilever mechanism assembly, a support assembly and a yoke, wherein the inner ring assembly is connected with the outer ring assembly through a pin; the outer ring assembly is connected with the support assembly through a pin; the cantilever mechanism assembly is connected with the outer ring assembly through an angle aluminium II; the angle aluminium II is in bolted connection with an outer support and an outer ring underframe; the yoke and the cantilever mechanism assembly are connected by adjusting a leading screw; relative to the outer ring assembly, the inner ring assembly is provided with a rotational degree of freedom; relative to the support assembly, the outer ring assembly is provided with a rotational degree of freedom; and therefore, relative to the support assembly, the sensor is provided with two rotational degrees of freedom, and the sensor can be adjusted according to the heeling condition of the inner and outer rings displayed by a sensor theodolite. The underwater verticality adjusting device for an ADCP sensor can solve the problem that an ADCP sensor cannot be arranged at the vertical position at any time because the measured data is not stable. The underwater verticality adjusting device for an ADCP sensor has the advantages of being high in stability, being high in accuracy and low in price.

Description

technical field [0001] The invention relates to an underwater verticality adjustment device of an ADCP sensor, which belongs to the technical field of hydrological monitoring. Background technique [0002] Water velocity measurement is one of the important tasks in the field of hydrology. With the development of science and technology, an ADCP (Acoustic Doppler Velocity Profile) uses the vertical profile of the location to measure the flow, which has high accuracy. In order to make the ADCP To obtain stable water flow data from the observation instrument, it is necessary to configure a bracket with a verticality adjustment device. The underwater verticality adjustment device of the ADCP sensor disclosed in the patent CN103105507A involves a worm and gear gearbox, a rocker mechanism, a linear bearing, and a guide rod mechanism, and has a complex structure, high assembly difficulty, and high cost; The height of the cantilever beam in the device is low, the verticality adjustm...
