Abstract

The invention discloses a black box pressure-resistant storage tank for a submersible vehicle. The black box pressure-resistant storage tank comprises a pressure-resistant cylinder, an elliptical head, a flat welding flange, a cover plate, reinforcing ribs, lifting lugs and lug plates. A black box for the submersible vehicle is installed on a black box base through a black box fastener, and a black box cable penetrates out of a tank through a cable cup-shaped pipe joint on a pressure-resistant cylinder and is sealed through a pressing gasket, a sealing filler and a cup-shaped pipe joint nut on the cable cup-shaped pipe joint. The cover plate is attached to the sealing face of the flat welding flange filled with the O-shaped sealing ring through a stainless steel surfacing face, the cover plate and the sealing face of the flat welding flange filled with the O-shaped sealing ring are pressed and sealed through a connecting bolt, a gasket and a nut which are made of stainless steel, and a discharging semi-penetration pipe fitting used for filling gas into the tank so as to check the gas tightness is welded to the cover plate. The discharging semi-penetration pipe fitting after inspection is sealed through an insulation sealing gasket and a sealing nut, and the inner surface and the outer surface of the tank body and the inner surface and the outer surface of the tank cover are coated with anti-corrosion coatings. The storage tank is resistant to high pressure, waterproof and anti-corrosion, and cable connection, tightness detection and operation are facilitated.

Description

technical field [0001] The invention belongs to the field of underwater pressure-resistant storage structures, in particular to a black box pressure-resistant storage tank for submersibles. Background technique [0002] The black box for submersibles is a kind of data recording equipment, which is placed in the outer superstructure of the pressure-resistant hull, and is used to collect and store the navigation data information of the own ship. It itself does not have waterproof ability, and it needs to be protected by a pressure-resistant storage structure. The existing black box pressure-resistant storage structure is resistant to seawater corrosion, poor sealing performance, complicated opening mechanism, and large volume, which is not conducive to the arrangement and removal in the narrow superstructure. Contents of the invention [0003] The purpose of the present invention is to provide a black box pressure-resistant storage tank for submersibles, which is high-pressu...
