A multi-chamber underwater towed body controlled by louvered forced sinking hydrofoils with attitude stability

Abstract

The invention discloses a window-blind-type forced sinking hydrofoil control posture stable multi-cabin underwater dragging body. The dragging body comprises a main body, a heaving control mechanism,a longitudinal inclination control mechanism and a bow changing control mechanism; instrument bins are of a streamline cavity structure, the three instrument bins are arranged in parallel at intervals, the instrument bins at the two sides and the instrument bin in the middle are in rigid connection through two fixed horizontal wings; a control bin is of a similar right-angled triangular prism structure; the bottom of the control bin is in rigid connection with the instrument bin in the middle through a stand column, the control bin is in rigid connection with the instrument bins at the two sides through two inclined struts; a fixed spoiler is fixed to the tail of the instrument bin in the middle; two guide pipe propellers are arranged at the tail ends of the instrument bins at the two sides, and a stern bin is arranged at the rear end of the control bin; a cable hole is formed in the front end of the control bin. The dragging body has the advantages that the heaving motion is stable tocontrol, the towing stability is good, control is flexible, and equipment arrangement is reasonable.

Description

technical field [0001] The invention relates to an underwater towed body, in particular to a louver-type forced-sink hydrofoil control attitude stable multi-chamber underwater towed body. Background technique [0002] The underwater towed body is an underwater device that is towed by ships, submarines or helicopters and sails under the water surface under the control of wired remote control to dynamically monitor the parameters of the underwater physical and chemical environment. Underwater towed body is one of the important means of marine environment monitoring, marine hydrological data observation, and marine disaster early warning. [0003] With the advancement of science and technology, the underwater towing body has developed from the earliest ones that can only drag in a straight line at a fixed depth or change the depth of water entry only by retracting and releasing cables, to the two-dimensional wave-like motion on the vertical surface that can be realized through ...

Problems solved by technology

How to enhance the towing stability and maneuverability of the underwater towing body in a simple and effective way is still one of the key technologies to be solved in the research and development of the underwater towing body. The existing multi-degree-of-freedom controllable underwater towing body often exists In the process of heave motion control, the attitude instability leads to problems such as the failure of the mounted optical sensor and other environmental detectors, and the ability to control the movement in the horizontal plane is also lacking. These deficiencies greatly affect the efficiency of underwater environment detection.
