Data protection unit fireproof layer

Abstract

The present invention discloses a data protection unit fireproof layer which comprises an upper shell, a fireproof blanket, an inner shell and a chassis. The upper shell is of a hollow barrel-shaped structure and is provided with an opening formed correspondingly to the chassis; the inner shell is arranged inside a cavity formed by the surrounding of the upper shell and the chassis; and the fireproof blanket is arranged between the inner shell and the cavity. The fireproof blanket is tightly filled between the inner shell and the cavity and no other contact except the fireproof blanket exists between the whole body formed by the marine data protection unit upper shell and the chassis and the inner shell, so that the inner shell is protected from being influenced by an external high temperature in an omnibearing manner. The chassis assembly of the data protection unit fireproof layer is also provided with a positioning apparatus which is fixedly connected with each wire. Data connection and power supply connection are not influenced by other factors.

Description

technical field [0001] The invention relates to a marine data protection unit, in particular to a fireproof layer of the data protection unit. Background technique [0002] The marine data protection unit is the most critical equipment in the shipboard voyage data recorder. It is the main component used to save the data items collected and recorded by the recorder, so as to do a good job in the status and output signals of the ship, the command order and operation control of the ship. etc. Backup jobs for pre-selected data items. In order to enable subsequent analysis of the relevant causes of marine casualties. [0003] The International Maritime Organization (IMO) has formulated the standard requirements for marine data protection units. In addition to the requirements for salt spray and watertightness, there are also a series of standards for sprinting, puncture, fire resistance, deep sea pressure and water resistance, etc. The fireproof layer is the main fireproof and ...

Problems solved by technology

This connection also brings a certain amount of heat conduction, which affects the performance of the fire protection layer

In addition, if there is no connecting device between the core or the heat insulation barrel of the marine data protection unit and the shell, the fireproof layer of the marine data unit will be loose relative to each layer, especially the looseness of the fireproof material and the data connection part. This loosening problem is exacerbated after rough sailing

Significantly affected the performance of MDU protection containers
