An acoustically positioned self-buoyant profiling buoy device

Abstract

The invention discloses an acoustic positioning type self-floating and sinking profile buoy device. Flanks are arranged on both sides of the buoy body, and a gyroscope and an acoustic transducer are arranged inside the buoy. The instrument obtains the movement attitude, and constantly adjusts the angle of the side wings to keep the horizontal distance between the floating and sinking buoys and the set sound source on the seabed fixed, so that the buoys in the self-buoyant-sinking profile move up and down repeatedly in a small range, and the self-buoyant-sinking profile The observation instruments carried on the buoy can measure the profile of marine environmental elements with the help of this rising and sinking movement. The acoustic positioning type self-floating and sinking profiling buoy device involved in the present invention only needs to be launched once, and can work quasi-in-situ for a long time, and the obtained profile data can be transmitted back to the ship or the ground receiving end in time through the antenna.

Description

technical field [0001] The invention relates to an ocean profile buoy measuring device, in particular to a self-floating and sinking ocean profile buoy measuring device that changes the motion trajectory by an acoustic signal. Background technique [0002] Profile measurement of marine environmental parameters is of great significance for oceanographic research, marine scientific investigation, fisheries assessment and maritime military activities. There are generally three ways to conduct profile measurement of marine environmental parameters: quick-disposal, ship-borne and fixed-sensor chain. The data obtained by the disposable and ship-borne type is densely distributed vertically and can be used for small-scale ocean analysis. However, when using it, the ship must be used repeatedly in the sea area to be tested, which requires many personnel, long time, and high cost. Moreover, long-term continuous profile data cannot be obtained. In the sensor chain method, the ship de...

Problems solved by technology

[0006] In view of the situation that the existing self-supporting profile observation buoy drifts with the waves and currents, and is prone to collide with ships and be damaged or float to the shore to stop working, the present invention introduces an acoustic positioning type self-floating and sinking profile buoy device. The buoy body has two The wings are set on the side, and the gyroscope and the acoustic transducer are installed in the buoy. The acoustic transducer receives the acoustic signal from the set sound source on the seabed, obtains the motion attitude through the gyroscope, and constantly adjusts the angle of the fins to maintain the balance of floating and sinking. The horizontal distance between the buoy and the set sound source on the bottom of the sea is fixed, so that the self-buoyant profile buoy moves up and down repeatedly in a small range to avoid drifting with the waves and currents
