Data protection container of navigation data recorder

Abstract

The invention provides a data protection container of a navigation data recorder. The data protection container comprises a container structure and a top cover structure. The top cover structure is arranged at the top of the container structure, and the top cover structure is mounted on the container structure through a fastening structure; the fastening structure and the container structure are installed in a hinged mode. The floating structure is arranged to enable the container to be integrated; after falling into the sea, the container can rise more quickly by virtue of the buoyancy of a floating ball; the whole air bag is adopted when the air bag is not used; an upper plastic plate and a lower plastic plate are directly rotated and then pressed down, so that the space occupied by thefolded air bag is further reduced; meanwhile, a wire between the upper part and the lower part in the air bag is spiral, so that a phenomenon of knotting due to rotation of the upper plastic plate andthe lower plastic plate is avoided; after the whole device is lifted to the water surface through the air bag, a fluorescent plate arranged at the top end can reflect certain light, the correspondingposition can be determined more accurately when the container is found, so that the searching and salvaging time is further shortened.

Description

technical field [0001] The invention belongs to the technical field of data recorders, and more specifically relates to a data protection container of a voyage data recorder. Background technique [0002] Data recorder, data recorder also refers to a marine black box, a special device that can provide important clues to the mysterious disappearance of a ship at sea. This kind of marine recorder that records sound, radar and other data on tape day and night is based on the use Developed by the black box. The sturdy case weighs around 90kg and uses eight-track tapes to record the sound of the engine control room as well as the background sounds of the boat as it sails. The entire system is housed in a half-meter-square waterproof case. placed in the wheelhouse. In addition, the tape can be disassembled in a fireproof and waterproof quick-float box on the deck. The date, time, compass and radar were all recorded. [0003] In the patent application number: CN201510654446.0, ...
