Controllable underwater towing body

Abstract

The present invention provides a controllable underwater towing body. It includes main body, two forced sinking hydrofils and attitute-stable float. Said invention also provides the concrete structure of the above-mentioned every portions. Said towing body has good attitude stability, strong autonomous stable power, high deep operation efficiency and simple control mechanism.

Description

technical field [0001] The invention relates to a carrier of a marine underwater detection device, in particular to a controllable underwater towing body. Background technique [0002] The controllable underwater towed body is a key component of the underwater towed system. It is towed by a surface towed ship through a towed cable to perform underwater detection tasks. Its body can be loaded with nutrients, pH values, etc. according to different purposes. Chemical element detection sensors or acoustic and photophysical detection sensors such as sonar and optical cameras. The operator on the tugboat can control the trajectory and attitude of the towed body through a certain control method to achieve the purpose of performing different underwater dynamic detection tasks. The working nature of the underwater environment detection sensor requires that the towed body has a stable attitude when working, and has fast and flexible attitude, trajectory adjustment and control capabil...

AI Technical Summary

Problems solved by technology

The main defect of this type of towed body in the form of a cylindrical main body is: the main body’s pitch and roll damping is small, resulting in a large pitch and roll angle of the towed body during the towing process. For its normal operation, it is necessary to constantly adjust the angle of attack of the control surface of the drag body, or artificially change the position of the drag point

This requires complex control mechanisms and manipulation actions, which increases the complexity of the design of the dragging body control system and the difficulty of user manipulation, making these dragging bodies difficult to obtain due to the complexity of the control mechanism, large structure, or difficulty in having good attitude stability. less than promotional use

On the other hand, some existing lightweight towed bodies are difficult to be satisfactorily used in actual underwater operations due to the single control action and difficulty in ensuring the stability of the towed body during operation.

Obviously, the above-mentioned defects of the existing controllable underwater towed body have become a major obstacle restricting the development of the controllable towed body to the practical direction
