Embodiment 1

[0040] like Figures 1 to 9 As shown, the embodiment of the present invention provides an anti-suffocation cutting device based on the separation signal of a person and a chair, comprising a metal electrode 1, a circuit board 2, a ring knife 3, an electric detonator 4 and a casing 5, wherein: installed on the seat On the metal electrode 1, the metal electrode 1 is connected to the circuit board 2 of the anti-suffocation cutting device through the contact electrode of the external circuit; one end of the ring knife 3 is fixed at the initial position through the rotating shaft 6; the actuating rod of the electric detonator 4 is The ring knife 3 provides thrust; the electric detonator 4, the ring knife 3 and the circuit board 2 are installed in the casing 5; the casing 5 is fixed on the bellows of the oxygen mask.

[0041] In this embodiment, after the bellows cutting device is activated, the working electrode turns on the circuit, and by monitoring the electrical signal of the p...

Embodiment 2

[0055] like Figure 10 As shown, an embodiment of the present invention provides an anti-suffocation cutting method based on a separation signal of a human chair, comprising the following steps:

[0056] (1) After the ejection life-saving device is activated, the pilot ejects out of the cabin in an emergency, and the life-saving system automatically separates the human seat when the life-saving system descends to a certain height, and the ejection seat sends a separation signal when the human seat is separated;

[0057] (2) The separation signal of the person and chair is transmitted to the bellows cutting device through the bellows through the electronic oxygen supply and anti-load regulator and helmet transfer;

[0058] (3) The bellows cutting device works by electric blasting to complete the cutting of the bellows of the oxygen mask. Under the action of tensile stress, the notch and the broken surface are opened to form an oxygen passage.

[0059] The human-chair separatio...

Abstract

The invention discloses an anti-suffocation cutting device and method based on a human-chair separation signal. The anti-suffocation cutting device comprises a metal electrode installed on a seat, and the metal electrode is connected with a circuit board of the anti-suffocation cutting device through a contact electrode of an external circuit; one end of the cutting ring is fixed at an initial position through a rotating shaft; an actuating rod of the electric exploder provides thrust for the cutting ring; wherein the electric exploder, the cutting ring and the circuit board are arranged in the shell; and the shell is fixed on a corrugated pipe of the oxygen mask. According to the device, the corrugated pipe cutting device is triggered by receiving a person-chair separation signal after catapulting off, an oxygen supply channel is opened before entering water, the problem that after emergency catapulting into the sea, an oxygen mask and an oxygen channel are blocked, and consequently a pilot is suffocated is effectively solved, and the safety of emergency catapulting is improved.

Description

technical field [0001] The invention relates to the technical field of aviation lifesaving, in particular to an anti-suffocation cutting device and method based on a separation signal of a human chair. Background technique [0002] Ejection is a common life-saving method for combat aircraft when they are in danger. When the pilot is ejected from the plane in an emergency, it is easy to fall into a coma due to unexpected circumstances, so that the oxygen mask cannot be taken off actively after landing, and it is easy to cause hypoxia drowning when in distress at sea. endanger the life of the pilot. The bellows cutting device is used to solve the problem of oxygen supply for the pilot after the parachute oxygen is exhausted when the pilot ejects from the plane according to the needs of lifesaving on the water. [0003] At present, the oxygen masks currently in service in China do not have the function of preventing suffocation by entering water. In foreign countries, some ox...
