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 discloses a deep-sea high-speed towing safety control system, which belongs to the technical field of deep-sea towing detection. The hull is connected and communicated with the data energy conversion bearing cabin through the tow cable, the data energy conversion bearing cabin is connected with the ballast through the hydroacoustic release device, and the pressure sensor and altimeter in the ballast are connected to the data through the feeder cable. The energy conversion bearing cabin; the data energy conversion bearing cabin and the detection towing body are connected and communicated through the umbilical cable, and the connection part between the umbilical cable and the detection towing body is equipped with a detachment device; Detect that the towed body touches the bottom or collides with obstacles; if the ballast release method fails, the release command is received through the underwater acoustic release device to complete the disconnection of the physical connection between the ballast and the data energy conversion bearing compartment. The invention can effectively reduce the probability of the bottoming accident of the ballast towing body, reduce the harm of the bottoming accident of the ballast towing body and improve the reliability of detecting the floating of the towing body.

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...
