Virtual anchoring profile buoy

Abstract

The invention discloses a virtual anchoring profile buoy. A posture adjustment module is arranged in an upper shell and comprises an inclination direction adjustment mechanism and a deflection adjustment mechanism. The inclination direction adjustment mechanism comprises an angle motor and a rotation frame driven by the angle motor. The angle motor is fixed into the upper shell. The central line of an output shaft of the angle motor coincides with the main axis of the buoy. The inclination direction adjustment mechanism is installed in the rotation frame and comprises a linear motor, a lead screw, a nut and an eccentric heavy block, wherein the lead screw is perpendicular to the output shaft of the angle motor, the lead screw is driven by the linear motor, the nut is connected to the lead screw in a threaded mode, the nut and the eccentric heavy block are fixedly connected, the eccentric heavy block is arranged in the rotation frame, the eccentric heavy block and the rotation frame are connected in a sliding mode, the linear motor is fixed to the rotation frame, and the linear motor and the eccentric heavy block are arranged on the two sides of the axis of the buoy respectively. The virtual anchoring function of a certain GPS point in the ocean can be achieved by adjusting the pose.

Description

technical field [0001] The invention belongs to the field of mechatronics, in particular to an autonomous motion platform for ocean environment profile observation. Background technique [0002] At present, the United States has independently developed three typical underwater glider, namely Seaglider of Washington University, Spray of Scripps Research Institute and Slocum underwater glider of Webb Research Company. All three underwater glider achieve floating by changing their own net buoyancy The three typical underwater gliders all highlight the function of forward movement, and their forward speed is relatively fast, which is suitable for Track the set path in the horizontal direction, however, its movement speed in the vertical direction is relatively slow, so it is not suitable for fast profile observation of the vertical water column at a certain GPS point. In addition, the current autonomous drifting profiling buoy that Argo plans to use achieves floating and diving...

[0002] At present, the United States has independently developed three typical underwater glider, namely Seaglider of Washington University, Spray of Scripps Research Institute and Slocum underwater glider of Webb Research Company. All three underwater glider achieve floating by changing their own net buoyancy The three typical underwater gliders all highlight the function of forward movement, and their forward speed is relatively fast, which is suitable for Track the set path in the horizontal direction, however, its movement speed in the vertical direction is relatively slow, so it is not suitable for fast profile observation of the vertical water column at a certain GPS point

In addition, the current autonomous drifting profiling buoy that Argo plans to use achieves floating and diving movements by changing its own net buoyancy. However, it does not have an attitude adjustment mechanism to achieve active movement in the horizontal direction, and can only drift with the current
