Embodiment Construction
[0015] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0016] According to one aspect of the invention, the present invention provides a thermal insulation bucket for marine data protection unit, such as figure 1 As shown, it includes an outer shell 1, an inner shell of a liquid layer and an upper cover 3 of a thermal insulation bucket. The shell 1 is a cylindrical stainless steel shell, and one end is provided with a first opening 13 corresponding in size and shape to the upper cover 3 of the heat-insulating bucket. The shell 1 is made of 304 stainless steel. The 304 stainless steel has the rust resistance and corrosion resistance suitable for the data unit in the marine environment, and has a certain high temperature resistance, which is conducive to the service life of the marine data unit. The inner shell of the liquid layer is arranged in the outer shell 1 and has a se...

The invention discloses a marine data protective unit heat insulation barrel which comprises an outer shell, a liquid layer inner shell and a heat insulation barrel upper cover. A liquid layer is installed between the liquid layer inner shell and the outer shell, a vacuum barrel and the outer shell share the same heat insulation barrel upper cover, a liquid layer is further installed inside the heat insulation barrel upper cover, and open holes and hole plugs are arranged on the outer shell and the heat insulation barrel outer wall and are matched with assembly of the liquid layers and vaporization heat release. Liquid inside the liquid layers of the outer shell and the heat insulation barrel upper cover is mixed liquid utilizing blue ice as principal raw material, and an appropriate unstable-state temperature is set through reasonable proportioning components. When the liquid layers absorb excessive heat, the liquid inside the liquid layers is evaporated to break through the hole plugs, and the heat is released outside the heat insulation barrel. By means of the structure, when the heat insulation barrel is continuously placed under the high temperature of 260 DEG C for 10 hours, the temperature of the liquid layer inner shell cannot exceed 80 DEG C.
Description
technical field [0001] The invention relates to a marine data protection unit, in particular to a heat insulation bucket of the marine 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. backup of pre-selected data items, etc., to enable subsequent analysis of the causes of marine casualties. [0003] The International Maritime Organization (IMO) has formulated standard requirements for marine data protection units. In addition to meeting the requirements for salt spray watertightness, they also need to withstand a series of standards such as sprint, puncture, fire resistance, deep sea pressure and water resistance, and marine data protection. The heat insulation...
