Description

Technical Field

[0001] The present application relates to the technical field of underwater vehicles, and in particular to a deep-sea pressure-resistant storage device for underwater vehicles and a method of using the device. Background Art

[0002] The voyage data recorder for underwater vehicles is a "legal" device, which is mainly used to record important information in various devices of underwater vehicles that is closely related to the safe navigation of underwater vehicles, and provide objective evidence for the investigation, analysis and judgment of underwater vehicle accidents. The data storage medium is the final storage medium of the voyage data recorder. When a major accident occurs in an underwater vehicle, the data stored in the data storage medium becomes an important key evidence. The data storage medium of the traditional voyage data recorder is arranged in the superstructure outside the pressure-resistant hull, which cannot directly withstand the large seawater pressure for a long time, and does not have the ability to communicate data underwater. It needs to be protected by a pressure-resistant storage structure outside it, which increases the volume and brings certain difficulties to the arrangement and salvage of the data storage medium. At the same time, the nominal storage capacity of the data storage medium of the traditional voyage data recorder is only 64GB at most, and there is not enough space to store the cabin video camera data, which greatly affects the type and amount of data stored in the data storage medium.

[0003] At the normal diving depth of the underwater vehicle, the data storage medium of the traditional navigation data recorder cannot directly withstand the seawater pressure, which directly affects the security of the data stored in the data storage medium. At the same time, when the underwater vehicle is navigating underwater, it is necessary to ensure that the navigation data recorder host in the cabin always transmits data to the data storage medium outside the cabin and stores it, and it is necessary to ensure that the data transmission link has a certain waterproof capability. The data storage medium of the navigation data recorder used in the traditional underwater vehicle is equipped with a pressure-resistant storage tank on the outer shell, and the longitudinal watertight cable enters the tank through the cable cup-shaped pipe joint on the pressure-resistant storage tank and connects to the data storage medium. However, when the underwater vehicle is diving, seawater sometimes penetrates into the pressure-resistant storage tank through the cable cup-shaped pipe joint, causing the data interface of the data storage medium to burn out due to water ingress. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a deep-sea pressure-resistant storage device and a method of use for underwater vehicles in response to the above-mentioned problems, which can reliably record more important information closely related to the safe navigation of underwater vehicles, thereby improving the navigation data recorder to provide more objective evidence for accident analysis and judgment.

[0036] like Figure 1-Figure 4 As shown, the present invention proposes a deep-sea pressure-resistant storage device for underwater vehicles, comprising a pressure-resistant inner cylinder and a pressure-resistant outer cylinder which are arranged inside and outside, a heat insulation component is filled between the pressure-resistant inner cylinder and the pressure-resistant outer cylinder, a data storage module 1 is placed in the pressure-resistant inner cylinder, a storage control module 2 is arranged on the top of the heat insulation component, a watertight connector socket 3, a discharge half-tank pipe 4, a cross reinforcement rib 5 and a handle 6 are arranged on the top of the pressure-resistant outer cylinder, and the storage control module is connected to the data storage module and the watertight connector socket through a communication line respectively.

[0037] Mounting holes are provided on the cross reinforcement ribs as an interface for fixing the outboard platform of the underwater vehicle. At the same time, a handle is provided on the pressure-resistant outer cylinder to meet the underwater lifting requirements of the deep-sea pressure-resistant storage device. The outboard platform base can be fixed in position through the mounting holes on the cross reinforcement ribs. When the deep-sea pressure-resistant storage device needs to be taken out, the bolts on the cross reinforcement ribs can be unscrewed and the handle can be grasped to take it out.

[0038] The heat insulation assembly includes an inner phase change heat insulation cylinder 7 and an outer heat insulation cylinder 8, which are respectively composed of a phase change cylinder body and a phase change cylinder cover and a heat insulation cylinder body and a heat insulation cylinder cover.

[0039] Furthermore, the pressure-resistant outer cylinder includes an outer cylinder shell 9 and an outer cylinder top cover 10.

The watertight connector socket is provided with a corresponding watertight connector socket cap 19 (see Figure 5 ).

[0047] A watertight connector socket is fixed on the top cover of the outer cylinder. The watertight connector is longitudinally watertight and resistant to high water pressure. The plug and the watertight cable can be made of vulcanization one-piece molding technology, which can meet the needs of transmitting data and power supply from the main engine in the cabin to the deep-sea pressure-resistant storage device.

[0048] Furthermore, the discharge half-pass tank pipe is embedded in the outer tube top cover and fixed by welding. The top pipe opening is connected and sealed by a sealing nut 20. A sealing gasket 21 is provided on the contact surface between the sealing nut and the top pipe opening (see Figure 6 ).

[0049] The deep-sea pressure storage device is filled with gas by discharging the half-pass tank pipe to check the tightness of the deep-sea pressure storage device. After the inspection, the sealing gasket and the sealing nut are tightened to keep the deep-sea pressure storage device sealed.

[0050] The method for using the above-mentioned deep-sea pressure-resistant storage device includes the following contents:

[0051] Place the inner phase change insulation cylinder and the outer insulation cylinder in the outer cylinder shell, place the data storage module in the inner cylinder shell, cover the inner cylinder top cover, and lead out the communication line connected to the storage control module, then place the pressure-resistant inner cylinder into the inner phase change insulation cylinder, cover the phase change cylinder cover and the insulation cylinder cover in turn, and lead out the communication line; place the fixing plate on the insulation cylinder cover, clamp the fixing plate with a spring clamp, and then fix the storage control module on the fixing plate, one end of the storage control module is connected to the communication line led out from the pressure-resistant inner cylinder to communicate with the data storage module, and the other end is connected to the watertight connector socket; when the watertight connector socket is connected to the watertight cable to communicate with the main engine in the cabin, the main engine in the cabin provides power to the deep-sea pressure-resistant storage device, and at the same time transmits the data information collected by the main engine in the cabin to the storage control module through the watertight cable, and the data is stored in the data storage module after being processed by the storage control module; when the watertight connector socket is not connected to the watertight cable, press the watertight connector socket cap on the watertight connector socket to prevent water from entering the watertight connector socket.
