An underwater glider attitude adjustment mechanism with full-angle pitch angle adjustment

Abstract

The invention discloses an underwater glider attitude adjustment mechanism for full-angle pitch angle adjustment, which includes a fixed seat, a support plate, a pitch limit plate, a swing rod, a swing rod fixing part, a lead screw fixing cover, a lead screw nut, and hexagonal fine teeth. Nut, trapezoidal screw, pitch motor, eccentric mass, self-lubricating bearing, supporting square tube, rolling motor, fixed slider, fixed plate, gear bearing end cover, cable sensor, angle sensor, swing rod self-aligning ball bearing, Self-aligning ball bearings, circular bushings, tension rods; the attitude adjustment mechanism is set inside the cabin of the underwater glider, and the front eccentric mass and the rear eccentric mass are driven by the pitch motor to move forward and backward along the axis or the front eccentric is driven by the roll motor The mass block and the rear eccentric mass block rotate circumferentially to change the position of the center of gravity of the underwater glider body, and cooperate with the buoyancy control system to return and discharge oil to realize the attitude adjustment of the underwater glider.

Description

technical field [0001] The invention belongs to the field of underwater gliders, in particular to an underwater glider attitude adjustment mechanism with full-angle pitch angle adjustment capability. Background technique [0002] Underwater glider is a new type of marine detection and monitoring equipment. It has the characteristics of long battery life, wide cruising range, low cost, easy operation and high degree of intelligence. By carrying different mission sensors, it can efficiently complete a variety of marine environment detection and information. Collect tasks. Its working principle is to use the buoyancy adjustment system to adjust the micro buoyancy and change the position of the center of gravity through the attitude adjustment mechanism to realize the sawtooth heave motion. The attitude angle adjustment is controlled by an eccentric mass block with a variable position inside the glider. With the in-depth study of underwater glider technology, there have been ma...

Problems solved by technology

[0003] However, the length of the underwater glider cabin is limited, and the more mature attitude adjustment mechanisms mentioned above cannot adjust the pitch angle in a wide range by axially moving the battery pack.
