Problems solved by technology

The disadvantage is that if the connection is broken, the floating board will lose its indication function
And to make the plank overcome the weight of the black box and float on the water surface, it will take a lot of plank, which takes up a lot of valuable volume on the aircraft, and the required plank is too large to be separated from the accident aircraft.

Embodiment 1

[0076] Embodiment 1, the black box and the buoyant black box in which vaporizable substance or compressed gas liquid nitrogen is directly packed in a sealed soft bag

[0077] Such as figure 1 , the black box 1 and the solid or liquid gasifiable substance or compressed gas 4 are packed into a sealed soft bag 2, and the sealed soft bag 2 is equipped with a solid or liquid gasifiable substance or compressed gas 4 that can be turned into gas; the sealed soft bag 2. The drainable weight of the maximum volume in the state of full gas or low-density gas is greater than the sum of the weight of all components of the entire buoyant black box. Vaporizable substance or compressed gas 4 uses liquid carbon dioxide. Put the floatable black box in an environment where the liquid carbon dioxide does not vaporize on the plane or ship, that is, provide the floatable black box with an environment of -20°C and 2.0 atmospheric pressure. Part of the sealed soft bag 2 is provided with conductive s...

Embodiment 2

[0078] Example 2, the black box is separated from the sealed soft bag, and the vaporizable substance or compressed gas liquid nitrogen is directly packed in the floatable black box in the sealed soft bag

[0079] Such as image 3 , the black box is separated from the sealed soft bag, but the black box 1 is connected with the sealed soft bag 2 with a soft rope 3 or a rigid object, and the sealed soft bag 2 is filled with a solid or liquid gasifiable substance or compressed gas 4 that can become a gas; sealed The maximum volume drainable weight of the soft bag 2 filled with gas or low-density gas state is greater than the sum of the weights of all components of the entire floatable black box. Vaporizable substance or compressed gas 4 uses liquid argon. Place the buoyant black box in an environment that does not vaporize liquid argon on an airplane or ship.

Embodiment 3

[0080] Embodiment 3, the black box is directly installed in a sealed soft bag, the vaporizable substance or compressed gas is packed in a storage container, and the sealed soft bag is connected to the storage container by a conduit with a valve to communicate with the floatable black box

[0081] Such as Figure 5 , the black box 1 is directly contained in the sealed soft bag 2, and the sealed soft bag 2 communicates with the storage container 7 containing the vaporizable substance or the compressed gas 4 through a conduit 9, and the conduit 9 is provided with an emergency valve 8; A device for separating the section 9 of the conduit between the emergency valve 8 and the storage container 7; the drainable weight of the maximum volume of the air-filled or low-density gas state in the sealed soft bag 2 is greater than the sum of the weight of all components of the entire buoyant black box. Vaporizable substance or compressed gas 4 selects liquid nitrogen for use, storage contain...

Abstract

The invention provides a floatable black box with an emergency gas bag, which relates to the technology that black boxes of a plane and a ship can float on the water after falling into the water. The black box is positioned into a seal soft bag or the black box is connected with the seal soft bag by a soft rope or a rigidity object, and solid or liquid gasifiable objects or compressed gas which can change gas are arranged in the seal soft bag which is fully filled with gas. When gas or low-density gas is fully filled into the seal soft bag, the largest-volume drainable quantity is larger than the total weight of the components of the floatable black box. The volume of the floatable black box is smaller in zero defects, the floatable black box can become a balloon body and float on the water in an accident, is easy to find, has no need to deeply salvage, is very easy to recover on the sea and greatly saves time and expense for recovering the black box.

Description

technical field [0001] The invention belongs to the technical field of aircraft black boxes, in particular to the technology that the black boxes of aircraft and ships can float on the water surface after being dropped into water. Background technique [0002] Now after an accident of an airplane or a ship, if the black box falls into the sea, even if the position of the black box can be detected by electronic equipment, it is difficult for divers to salvage the black box. In particular, the black box fell into the deep sea above 3,000 meters, and neither divers nor robots could salvage the black box. Even if it falls into the shallow sea, it will take time, effort and money to salvage the black box. [0003] China 02236272.X "Aircraft Black Box Positioning Float" discloses a device for indicating the position of an aircraft black box falling into water, especially relates to a kind of aircraft black box positioning float, including the black box, which is characterized in ...
