Floating protector for black box

Abstract

The invention discloses a floating protector for a black box. The floating protector comprises a positioning base, a laser positioning assembly and a data recording assembly; the positioning base is arranged at the bottom part of the laser positioning assembly; the data recording assembly is arranged at the top part of the laser positioning assembly; the top part of the positioning base is provided with an elastic plugging sleeve and base permanent magnets; the laser positioning assembly includes a pressure-resistant cover body, a positioning storage battery, a compressed nitrogen tank and a laser emission floating ball body; and a pressure-resistant sealing cavity and a fixed countersink are arranged in the pressure-resistant cover body. According to the floating protector, according to the laser beam riding guidance principle, after being analyzed by an error signal analysis processor, a command is transmitted to a horizontal driving motor or a longitudinal driving motor to drive driving impellers to rotate, thereby guaranteeing that the data recording assembly is within the range of a laser beam all the time, preventing the data recording assembly from drifting along, and facilitating accurate positioning.

Description

technical field [0001] The invention relates to the technical field of aircraft black boxes, in particular to a black box floating protection device. Background technique [0002] As we all know, the "aircraft black box" is one of the special electronic recording devices for aircraft. It can record voice conversations half an hour before the aircraft stops working or crashes and two hours of flight altitude, speed, heading, rate of climb, rate of descent, acceleration, consumption, etc. Flight parameters such as fuel volume, landing gear retraction and GMT, as well as aircraft system operating conditions and engine operating parameters are all recorded. However, the timely acquisition of the aircraft black box needs to be determined by the environment and geographical location of the aircraft crash. There are still some deficiencies in the black box device of the aircraft: 1. The black box is usually installed at the tail of the aircraft, a position with a high safety factor...

[0002] As we all know, the "aircraft black box" is one of the special electronic recording devices for aircraft. It can record voice conversations half an hour before the aircraft stops working or crashes and two hours of flight altitude, speed, heading, rate of climb, rate of descent, acceleration, consumption, etc. Flight parameters such as fuel volume, landing gear retraction and GMT, as well as aircraft system operating conditions and engine operating parameters are all recorded. However, the timely acquisition of the aircraft black box needs to be determined by the environment and geographical location of the aircraft crash. There are still some deficiencies in the black box device of the aircraft: 1. The black box is usually installed at the tail of the aircraft, a position with a high safety factor, and a fixed connection is generally used. When the aircraft encounters a shipwreck, the black box will fall into the deep sea with the aircraft and it is difficult to salvage; 2. When the black box is separated from the accident aircraft, the black box does not have its own drive system and usually sinks to the bottom of the sea, and search and rescue personnel cannot obtain it at a fixed point; 3. Because the sea water is in a state of motion, the black box usually moves with the undercurrent of the seabed, which makes it difficult for search and rescue personnel Looking for, so the present invention provides a kind of black box floating protection device
