Description

Technical Field

[0001] This invention belongs to the field of aviation lifesaving technology, and in particular relates to a lifesaving radio activation mode conversion device. Background Technology

[0002] When an aircraft is in distress, after the pilot activates the central pull ring of the rocket ejection seat (hereinafter referred to as the seat), they separate from the seat in mid-air, carrying life-saving equipment. The life-saving radio inside the seat's life-saving pack must automatically activate simultaneously with the separation of the pilot and seat when needed, and can be deactivated when not needed. Once activated, the life-saving radio will automatically transmit the pilot's location beacon, allowing rescuers to quickly determine the pilot's location and initiate rescue operations.

[0003] Traditional escape radios activate automatically via escape radio floats. The activation occurs simultaneously with the separation of the escape seat, relying on the weight of the escape pack's internal life support components after the pack opens to pull the activation pin. Traditional methods lack a mode-off function; once ejected from the rocket ejection seat, the escape radio activates simultaneously. If ejected in enemy-occupied territory, this quickly reveals the pilot's position, hindering rescue efforts. Summary of the Invention

[0004] Purpose of the invention

[0005] To overcome the problem that the rescue radio cannot be turned off in the prior art, this invention provides a rescue radio start-up mode switching device. This device can switch modes at any time when needed. In automatic mode, the rescue radio can automatically start when the person and chair are separated; in manual mode, the radio can be disconnected from the safety pin when the person and chair are separated, without affecting the normal separation of the person and chair.

DETAILED DESCRIPTION

[0031] The present application is realized by the following technical scheme.

[0032] The present application is used for lifesaving radio starting mode conversion of lifesaving bag internal packaging of rocket ejection seat.

[0033] As Figure 1 , lifesaving bag 3 is fixed between inner rubber gasket 11 and outer rubber gasket 12 of the converter.

[0034] As Figure 2As shown, the life-saving radio starting mode conversion device of the present application comprises a converter 1 and a constant force connecting rope 2. The converter 1 is installed on the seat of the life-saving bag 3, and the constant force connecting rope 2 passes through the middle hole of the converter 1 and is connected to the life-saving radio starting pull pin at one end and to the seat chair basin bottom plate at the other end. In the automatic mode, when the person and the chair are separated, the seat gravity pulls the life-saving radio starting pull pin to realize the self-starting of the life-saving radio; in the manual mode, when the person and the chair are separated, the seat pulls the constant force connecting rope to break the safety 16, which does not affect the separation of the person and the chair, and the life-saving radio will not start. The pilot manually opens the life-saving radio at the appropriate time according to the actual needs to release the distress signal.

[0035] As shown in Figure 3 , Figure 4 , the converter 1 is composed of a cover sheet 5, a sliding groove sheet 6, a sliding sheet 7, a steel ball 8, a compression spring 9, a gasket layer 10, an inner rubber gasket 11, an outer rubber gasket 12, and a bottom sheet 13. One end of the gasket layer 10 has a sleeve 20, which passes through the inner rubber gasket 11, the life-saving bag 3, and the outer rubber gasket 12 in sequence and is threadedly connected to the bottom sheet 13. The compression spring 9 is located in the holes 21 on both sides of the sleeve 20 in the axial direction. The inner hole of the sleeve 20, the through hole on the sliding groove sheet 6, and the special-shaped hole 24 on the sliding sheet 7 provide a channel for the constant force connecting rope 2. The specification and model of the compression spring 9 determine the size of the thrust during mode conversion. The steel ball 8 is located on the compression spring 9. The bosses 22 on the sliding groove sheet 6 pass through the holes on the corresponding positions of the sliding sheet 7 and are connected to the other end of the gasket layer 10, pressing the steel ball 8 and the compression spring 9 tightly. The cover sheet 5 is connected to the sliding sheet 7. The main function of the converter 1 is to fix the life-saving bag 3 and provide a channel for the constant force connecting rope 2. The cover sheet 5 is fixed to the end of the sliding groove sheet 6 away from the gasket layer 10. The cover sheet 5 has a through hole coaxial with the through hole on the sliding groove sheet.

[0036] As shown in Figure 5 , the constant force connecting rope 2 includes a spring hook 14, a main rope 15, a safety 16, a main rope 2, and a connecting ring 18 connected in sequence. The main rope 2 is provided with a steel ball 17. The spring hook 14 is hung on the connecting ring of the seat chair basin bottom plate. The connecting ring 18 passes through the special-shaped hole 24 in the middle of the sliding sheet 7 and is connected to the life-saving radio starting pull pin connecting ring 19. The breaking force of the safety 16 is greater than the starting force of the life-saving radio starting pull pin and less than the breaking force of the life-saving radio starting pull pin. The main rope 2 needs to be knotted and positioned at the rear side of the steel ball 17 (close to one end of the connecting ring 18).

[0037] As shown in Figure 7 , the four bosses 22 on the sliding groove sheet 6 pass through the waist-shaped holes on the corresponding positions of the sliding sheet 7 and are connected to the gasket layer 10, pressing the steel ball 8 and the compression spring 9 tightly. By pushing and pulling the sliding sheet 7, the bosses 22 on the sliding groove sheet 6 can move relatively in the waist-shaped holes of the sliding sheet 7.

[0038] As shown in Figure 8The four round shallow grooves on the end of the slide piece 7 near the gasket layer 10 are suitable for the steel ball 17, and the steel ball 17 can be partially contained in the shallow grooves. Every two shallow grooves are located in the sliding route of one steel ball 17. The four shallow grooves and the four waist-shaped holes determine the stroke of the steel ball 8 and the stroke of the slide piece 7. The slide piece 7 has a "key" hole in the middle, which can show a circle or a "I" shape (displayed in the through hole of the cover piece 5 and the slide groove piece) on the converter 1 when pushed on the converter 1. When the circle is displayed, the steel ball 17 on the constant force connecting rope 2 can pass through; when the "I" shape is displayed, the steel ball 17 on the constant force connecting rope 2 is blocked and cannot pass through, thereby meeting the needs of the pilot for the mode conversion of the survival radio station. The "←M" (towards the "I" shape direction) and "→A" (towards the circle direction) can be marked on the upper side of the slide piece 7 to clearly indicate the movement direction of the slide piece, and the red and green mark lines (which can also be changed to other colors according to needs) are respectively marked on the two sides of the end face of the other end of the gasket layer 10 to indicate that the slide piece 7 is pushed to the position. The "I" shape or the circle of the slide piece 7 is displayed on the converter 1 when the steel ball 17 slides into the shallow groove. In order to facilitate the push-pull of the slide piece, a convenient gripping structure can be provided on the edge of the slide piece as the slide piece pushing end 23, such as a bent structure, a convex edge with a slot hole, etc.

[0039] When the pilot pushes the mode to the automatic mode and the pilot-seat is separated, the seat pulls the constant force connecting rope 2 to first pull the survival radio station starting pull pin connecting ring 19 to realize the self-starting of the survival radio station, and then disconnects from the safety device 16, so that the pilot-seat is normally separated. When the pilot pushes the mode to the manual mode and the pilot-seat is separated, the seat pulls the constant force connecting rope 2, and the steel ball 17 on the constant force connecting rope 2 is blocked by the "I" slot on one side of the special-shaped hole, so that the constant force connecting rope 2 is directly disconnected from the safety device 16, which does not affect the separation of the pilot-seat, and the survival radio station will not be started. The pilot manually opens the survival radio station at the appropriate time according to the actual needs to release the distress signal.
