Problems solved by technology

At first, it was mainly used in military affairs. Its movement method is to drag in a straight line at a fixed depth. The change of depth is realized by changing the length of the cable and changing the speed of the ship. The purpose is also single, and it is only used for detecting targets.
From the end of the 20th century to the present, tow body technology has been widely used in the field of marine monitoring, equipped with sensors for various purposes, but all use two-dimensional control, that is, to control the tow body to perform wave-like movement underwater, but not to control the attitude of the tow body. The trim angle is too large when the drag body rises and dives, so it is not suitable for carrying acoustic or optical sensors

Abstract

The invention relates to a full-depth three-dimensional control dragger comprising a main streamline body, sweeping type wings, a tail wing, a fence and a drag bar, wherein the sweeping type wings are positioned at both sides of the main streamline body in a connecting way; the tail wing is positioned on the tail part of the main streamline body in a connecting way; the fence is positioned below the main streamline body in a connecting way; a rotating shaft of the sweeping type wings is connected with the drag bar; the tail wing is in an H shape and comprises a tail wing fixing frame, an automatic heeling control device and a tail wing control machine, wherein the middle of the tail wing fixing frame is fixedly connected with the tail part of the main streamline body, the upper end of thetail wing fixing frame is connected with the automatic transverse-inclination control device, and the lower end of the same is connected with the tail wing control machine. The invention realizes thethree-dimensional control of the dragger and can control the posture of the dragger in water, prevent a trim angle from being overlarge when the dragger ascends or descends, automatically regulate the heeling of the dragger according to the state of the dragger in the water and ensure that the dragger is stably operated.

Description

technical field [0001] The invention relates to a towed carrier in water, in particular to a large-depth three-dimensional control towed body capable of carrying various sensors such as ocean monitoring, acoustics, and optics, and used for profile measurement of various ocean physical and chemical parameters. Background technique [0002] The towing body is dragged by the mother ship through cables, and its technology has been researched and developed for decades. Initially, it was mainly used in military affairs. Its motion method was tow in a straight line at a fixed depth. The change of depth was realized by changing the length of the cable and changing the speed of the ship. From the end of the 20th century to the present, tow body technology has been widely used in the field of marine monitoring, equipped with sensors for various purposes, but all use two-dimensional control, that is, to control the tow body to perform wave-like motion underwater, but not to control the...
