Problems solved by technology

[0009] At present, most of the domestically produced marine data protection units are designed purely from the perspective of blocking heat conduction, and the internal structure and outlet methods are mostly disordered after a long and turbulent voyage, which greatly affects the performance and use of the marine data protection unit. life

Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0024] Such as figure 1 As shown, the present invention describes a marine data protection unit, which includes an outer shell, a thermal insulation bucket and a core. The heat insulation barrel is located between the outer casing and the inner core, a fireproof layer 2 is arranged between the outer casing and the heat insulation barrel, and a paraffin layer 4 is arranged between the heat insulation barrel and the inner core.

[0025] The outer casing includes an upper casing 11, a base 12 and a chassis 13, and the chassis 13 is fixed on the inner side of the bottom of the upper casing 11 by bolts. Strip hole 14 is arranged.

[0026] The heat-insulating barrel includes a heat-insulating barrel shell 31, a liquid layer 32, a vacuum barrel 33 and a heat-insulating barrel cover 34. There is a gap 35 on the edge of the heat-insulating barrel cover 34, and the v...

Abstract

The invention discloses a ship data protection unit which comprises an outer shell, a heat insulation barrel and an inner core, wherein the heat insulation barrel is located between the outer shell and the inner core, a fireproof layer is arranged between the outer shell and the heat insulation barrel, and a paraffin layer is arranged between the heat insulation barrel and the inner core. Through the modularized design, the functions of various layers are independent, the ship data protection unit is dismountable, the assembly and maintenance costs are lower, the various layers independently wrap the inner layers, no physical connection exists between a carrier for storing backup data, namely an electronic hard disc, and the other layers except the adjacent two layers, so that heat can be avoided being transferred to the electronic hard disc through physical connection.

Description

technical field [0001] The invention relates to a ship-borne navigation device, in particular to a data backup storage device for a ship-borne navigation data recorder. Background technique [0002] The marine data protection unit is the most critical equipment in the ship-borne voyage data recorder. The ship-borne voyage data recorder is a ship-borne voyage data recorder that is used for international voyages in accordance with relevant requirements and records the status and output of the relevant ship. Pre-selected data items such as signals, ship command orders, and operational controls. [0003] The data items collected and recorded by the shipboard voyage data recorder are stored in the main engine, and are also transmitted to the marine data protection unit through the data cable as a backup. The role of the marine data protection unit is to enable subsequent analysis of the relevant causes of marine accidents. [0004] The International Maritime Organization (IMO) h...
