Towed line array head-rope mini-type connecting structure

Abstract

The invention provides a towed line array head-rope mini-type connecting structure which comprises a conical hole nut, a conical hole screw rod and head-ropes. The head-ropes comprise the first head-rope and the second head-rope connected with the first head-rope. The inner surface of the conical hole nut is connected with the outer surface of the first head-rope. The inner surface of the conical hole screw rod is connected with the outer surface of the second head-rope. The conical hole nut is in threaded connection with the conical hole screw rod. High-strength reliable connection of broken kevlar ropes can be quickly achieved in small space in a towed line array PU sheath, maintenance time is remarkably shortened, and maintenance cost is remarkably reduced. Chamfers of 1 mm are formed at the through hole end of the conical hole nut and the through hole end of the conical hole screw rod, the towed line array head-rope mini-type connecting structure is suitable for the towed line array winding and bending state, and the kevlar ropes are prevented from being damaged by sharp corners.

Description

technical field [0001] The invention relates to the technical field of towed line arrays of underwater acoustic equipment such as seabed oil exploration in ocean engineering, and in particular to a micro-connection structure of load-bearing ropes of towed line arrays. Background technique [0002] The towed line array is the core component of underwater acoustic equipment such as marine engineering submarine oil exploration equipment. It is mainly composed of kevlar load-bearing ropes, hydrophones, PU sheaths, supporting structures and signal amplification and transmission circuits. The PU sheaths are filled with lightweight Oil. In order to improve the detection ability of the echo signal of the seabed formation, the towed line array is generally hundreds of meters long to accommodate enough hydrophones. The towed line array is subjected to seawater resistance during the towing process. In order to ensure that the distance between the hydrophones remains unchanged, kevlar ...

AI Technical Summary

Problems solved by technology

During operation or maintenance, once the kevlar load-bearing rope of the tow line array is cut, the kevlar rope of the entire tow line array must be removed and replaced, so there are problems such as large maintenance workload and high cost of the tow line array kevlar load-bearing rope

[0004] At present, no technology of the same type as the present invention exists, and no similar method exists in documents and documents
