Abstract

The invention discloses a flounder-type underwater glider. An electronic cabin comprises a pressure-resisting cabin, a gravity and gravity center adjustment mechanism, a control system and a lithium battery unit. The inside of the pressure-resist cabin is partitioned into a central area, a middle circular area and an outer circular area. The lithium battery unit is arranged in the middle circular area. The control system includes an overwater control system and an underwater control system which are connected in a wireless manner. The underwater control system and the electronic part of surveying equipment are arranged in the middle circular area uniformly. The gravity and gravity center adjustment mechanism comprises four water bag pump units in same structure, and the four water bag pump units are distributed in the outer circular area symmetrically. The flounder-type underwater glider has the advantages of low cost, low noise, high endurance and high flexibility; the gravity and posture of the glider can be adjusted to realize zigzag or spiral trajectory through controlling the four water bag pump units distributed symmetrically. The flounder-type underwater glider can carry a plurality of underwater scientific-investigation and survey devices simultaneously, continuous data collection in extensive sea areas can be completed automatically, and the data can be transmitted back in real time.

Description

technical field [0001] The invention relates to the technical field of underwater glider, in particular to a flounder-type underwater glider. Background technique [0002] Underwater Glider (Underwater Glider) is a new type of autonomous underwater vehicle (Autonomous Underwater Vehicle: AUV). It adopts buoyancy drive mode to complete zigzag or spiral orbital navigation underwater, and has the advantages of low energy consumption, high efficiency, large endurance (up to thousands of kilometers), low cost and low maintenance cost, and is widely used in long-term , Large-scale marine surveys. In addition, since there is no power mechanism such as a propeller, the noise of the glider is extremely low, so it is of great value in military applications. [0003] At present, there are four mature models of underwater gliders in the world, namely: Spray Glider developed by Scripps Institution of Oceanography (SIO), Sea Glider developed by University of Washington (UW) , Slocum El...
