Problems solved by technology

However, for the deep-sea high-speed towing system (towing speed 5-6kn), the possibility of ballast towing body bottoming accidents during high-speed towing increases, and the damage is intensified. After a failure, the reliability requirements for the release of the towing body after a fault are higher. The original safety control measures can no longer meet the demand. It is urgent to further improve the safety control strategy of deep-sea towing and improve the safety of deep-sea high-speed towing equipment.

Abstract

The invention, which belongs to the technical field of deep sea dragging detection, discloses a deep sea high-speed dragging safety control system. A ship body is connected and communicated with a data energy conversion force-bearing cabin through a towing cable, the data energy conversion force-bearing cabin is in force-bearing connection with a ballast device through an underwater acoustic release device, and a pressure sensor and an altimeter in the ballast device are connected with the data energy conversion force-bearing cabin through a feed cable; the data energy conversion force-bearingcabin is connected and communicated with a detection towed body through an umbilical cable, and a cable releasing device is arranged at the connecting part of the umbilical cable and the detection towed body; the ballast device prevents the detection towed body from touching the bottom or colliding with an obstacle in a ballast release mode; and if the ballast release mode fails, the underwater acoustic release device receives a release instruction to complete disconnection of physical connection between the ballast device and the data energy conversion force-bearing cabin. According to the invention, the probability of a grounding accident of the ballast towed body can be effectively reduced, the harm of the grounding accident of the ballast towed body is reduced, and the floating reliability of the detection towed body is improved.

Description

technical field [0001] The invention relates to a deep-sea high-speed towing safety control system, in particular to a safety control strategy and composition of a deep-sea high-speed towing system, and belongs to the technical field of deep-sea towing detection. Background technique [0002] The safety design of deep-sea towed equipment is one of the key technologies of the deep-sea towed detection system, and it must be considered in the development of deep-sea towed detection equipment. [0003] At present, the international deep-sea towing system mostly adopts two-stage towing mode (gravity ballast towing body + weak positive buoyancy towing body), the towing speed is generally 1-2kn, and its safety design mainly considers the redundant design of towing cable strength and towing failure. The underwater acoustic release of the rear detection towing body, the satellite communication and cursor indication after the detection of the towing body's floating surface, etc., bett...
