Detachable bottom-supported ADCP(acoustic doppler current profiler) bearing device

Abstract

The invention discloses a detachable bottom-supported ADCP(acoustic doppler current profilers) bearing device. The detachable bottom-supported ADCP bearing device comprises a support frame, an outer frame, an inner frame and a bottom contact prevention rack, wherein the outer frame has a rotational degree of freedom relative to the support frame; the inner frame has a rotational degree of freedom relative to the outer frame; the bottom contact prevention rack limits a bottom contact surface of the bearing device on four surfaces; and an ADCP is fixed to a fixed rack of the inner frame. According to the detachable bottom-supported ADCP bearing device, after the bearing device is put to the sea bottom, the ADCP can be adjusted to the position perpendicular to a water current through the entire structure design; clump weights are connected to the inner frame, so that after the ADCP is sunken to the sea bottom, the front surface is not upside-down; the entire structure adopts a detachable connection manner, so that maintenance is facilitated; and the ADCP can be prevented from being interfered by benthos through the support frame, the outer frame, the inner frame and the bottom contact prevention rack, so that the detection result is more stable.

Description

technical field [0001] The invention relates to the field of mechanical processing, and more specifically relates to a detachable bottom-sitting ADCP carrying device. Background technique [0002] The full name of ADCP is Acoustic Doppler Current Profilers, which refers to the acoustic Doppler current profiler. It is a flow measurement device developed in the early 1980s that uses the principle of the Doppler effect to measure flow velocity. ADCP is superior in principle. It breaks through the traditional mechanical rotation-based sensor current meter, and uses an acoustic transducer as a sensor. The transducer emits acoustic pulse waves, and the acoustic pulse waves pass through anti-scatterers such as sediment particles and plankton that are unevenly distributed in the water body. In backscattering, the signal is received by the transducer, and the flow velocity is calculated by measuring the Doppler frequency shift. ADCP has the characteristics of being able to directly ...

Problems solved by technology

According to actual needs, each type of bearing device will be different. For the bottom-mounted type of load-bearing device, the difficulty is due to the complex topography of the seabed, unevenness, or uneven subsidence of the support point, which causes the load-bearing device to tilt, so the bottom-mounted type requires a universal mechanism. After the ADCP is put into the seabed, it can be adjusted to the position of the vertical water flow. At the same time, it is necessary to consider avoiding the effect of the water flow to make it tilt, thus affecting the monitoring accuracy
