Problems solved by technology

[0004] With the continuous development of towing technology, in order to realize a certain complex working mode or realize certain functions, when multiple acoustic units need to be carried in the towing system at the same time, when a single towing body cannot accommodate multiple acoustic units, it is necessary to carry multiple towing units. When the body is towed underwater at the same time, the towing mode of this single-cable single-towing body cannot meet the actual needs

Abstract

The invention discloses a flexible vertical towing chain system for an underwater multi-towed body, including triangular trailers, a connection point at the top of the triangular trailer is rotatablyconnected to the tractor of the streamer, Is the drag point of the entire drag chain, at the front and rear connection point of the low half of the triangular trailer, a lead chain is mainly compose of a lead chain body, Lower rotational shaft configuration, a lead chain body is connected with a triangular trailer, a low rotating shaft is connected with that lower end of the lead chain body, the lower rotating shaft is connected with the suspension chain, front and rear suspension points are arranged on the towing body unit, the two suspension points are respectively suspended with the front and rear suspension chains through a unit connecting shaft, and a plurality of towing body units are simultaneously hitched on the two suspension chains according to actual requirements. The inventionrelates to a novel underwater towing structure mode suitable for multi-towed bodies, which can simultaneously carry multiple acoustic units for underwater target detection, topography and geomorphology exploration, marine scientific investigation, military investigation and the like.

Description

technical field [0001] The invention relates to the field of underwater towing systems, in particular to a flexible vertical towing chain system for multiple underwater towing bodies. Background technique [0002] The research and development of the towed system has a history of several decades. From the end of the 20th century to the present, the towed diversion technology has been widely used in the marine field, equipped with various acoustic instruments for different purposes, and applied in marine scientific investigations, military investigations, target detection, seabed Topographic and geomorphic surveys, marine environmental surveys, etc. [0003] Common active towing systems mostly use a single towing body scheme. As the name implies, this scheme consists of a single towing body. Acoustic sensors are arranged inside the towing body. Change the working depth of the dragged body. The structure of such a towing system is relatively simple, the technology is relative...
