Description

Technical Field

[0001] The invention belongs to the technical field of aviation life-saving, and in particular relates to a life-saving radio station startup mode conversion device. Background Art

[0002] When the aircraft is in distress, the pilot activates the central pull ring of the rocket ejection seat (referred to as the seat), and then separates the pilot from the seat in the air with life-saving items. The life-saving radio in the life-saving bag in the seat is required to be automatically activated when needed and can be turned off when not needed. After the life-saving radio is activated, it will automatically send the pilot's location beacon so that rescuers can quickly determine the pilot's location and start rescue operations.

[0003] The self-start of the traditional life-saving radio is achieved through the life-saving radio floatation bag. The self-start of the life-saving radio occurs at the same time as the separation of the person and the chair. After the life-saving items in the life-saving bag are opened, the gravity of the life-saving radio is used to pull the life-saving radio start pin to achieve the self-start of the life-saving radio. The traditional method has no mode shutdown function. Once the rocket ejection seat is ejected out of the cabin, the life-saving radio will start synchronously. If it is ejected in the enemy-occupied area, it will quickly expose the pilot's position, which is not conducive to the rescue of the pilot. Summary of the invention

[0004] Purpose of the Invention

[0005] In order to overcome the problem that the life-saving radio cannot be turned off in the prior art, the present invention provides a life-saving radio startup mode conversion device. The device can switch modes at any time when needed. In the automatic mode, when the person and the chair are separated, the life-saving radio can be automatically started synchronously; in the manual mode, when the person and the chair are separated, it can be disconnected from the safety part without affecting the normal separation of the person and the chair.

DETAILED DESCRIPTION

[0031] The present invention is achieved through the following technical solutions.

[0032] The invention is used for switching the start-up mode of the life-saving radio station packed inside the rocket ejection seat life-saving bag.

[0033] like Figure 1 The life-saving bag 3 is fixed between the inner rubber gasket 11 and the outer rubber gasket 12 of the converter.

[0034] like Figure 2As shown, a life-saving radio start mode conversion device of the present invention includes a converter 1 and a fixed force connecting rope 2. The converter 1 is installed on the life-saving bag 3 on the seat, and the fixed force connecting rope 2 passes through the middle hole of the converter 1 and is connected to the life-saving radio start pin at one end, and the other end is connected to the seat basin bottom plate. In automatic mode, when the person and the chair are separated, the life-saving radio start pin is pulled by the gravity of the seat to realize the self-start of the life-saving radio; in manual mode, when the person and the chair are separated, the seat pulls the fixed force connecting rope to disconnect from the fuse 16, which does not affect the separation of the person and the chair, and the life-saving radio will not start. The pilot can manually turn on the life-saving radio at an appropriate time according to actual needs to release a distress signal.

[0035] like Figure 3 , Figure 4 As shown, the converter 1 is composed of a cover plate 5, a slide plate 6, a sliding plate 7, a steel ball 8, a compression spring 9, a cushion layer 10, an inner rubber gasket 11, an outer rubber gasket 12, and a bottom plate 13. The cushion layer 10 has a sleeve 20 at one end, and the sleeve 20 passes through the inner rubber pad 11, the life-saving bag 3, and the outer rubber pad 12 in sequence and is threadedly connected to the bottom plate 13. The compression spring 9 is located in the holes 21 along the axial direction on both sides of the sleeve 20. The inner hole of the sleeve 20, the through hole on the slide plate 6, and the special-shaped hole 24 on the sliding plate 7 provide a channel for the fixed force connecting rope 2. The specification and model of the compression spring 9 determine the magnitude of the thrust during the mode conversion. The steel ball 8 is located on the compression spring 9. The boss 22 on the slide plate 6 passes through the hole at the corresponding position on the sliding plate 7 and is connected to the other end of the cushion layer 10 and compresses the steel ball 8 and the compression spring 9. The cover plate 5 is connected to the sliding plate 7. The main function of the converter 1 is to fix the life-saving bag 3 and provide a channel for the fixed force connecting rope 2. The cover sheet 5 is fixed to the end of the slide slot sheet 6 away from the cushion layer 10. The cover sheet 5 has a through hole coaxial with the through hole on the slide slot sheet.

[0036] like Figure 5 As shown, the fixed 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 which are connected in sequence. A steel ball 17 is arranged on the main rope 2, and the spring hook 14 is hung on the connecting ring of the seat basin bottom plate. The connecting ring 18 first passes through the middle special-shaped hole 24 of the sliding plate 7, and then is connected to the life-saving radio station start-up pin connecting ring 19. The breaking force at the safety 16 is greater than the starting force of the life-saving radio station start-up pin, and is less than the destructive force of the life-saving radio station start-up pin. The main rope 2 is located at the rear side of the steel ball 17 (close to one end of the connecting ring 18) and needs to be knotted for positioning.

[0037] like Figure 7 The four bosses 22 on the chute sheet 6 pass through the waist-shaped holes at the corresponding positions on the sliding sheet 7 and are connected to the cushion layer 10, and the steel ball 8 and the compression spring 9 are compressed. By pushing and pulling the sliding sheet 7, the bosses 22 on the chute sheet 6 can generate relative movement in the waist-shaped holes of the sliding sheet 7.

[0038] like Figure 8The sliding plate 7 has four shallow circular grooves at one end close to the cushion layer 10, which are suitable for the steel ball 17. The steel ball 17 can be partially accommodated in the shallow grooves. Every two shallow grooves are located on the sliding path of a steel ball 17. The size of the four shallow grooves and the four waist-shaped holes determines the stroke of the steel ball 8, and also determines the stroke of the sliding plate 7. The sliding plate 7 has a "key"-shaped hole in the middle, which can display a circle or a "one" shape on the converter 1 as it is pushed (displayed in the through holes on the cover plate 5 and the slide plate). When the circle is displayed, the steel ball 17 on the fixed force connecting rope 2 can pass through; when the "one" shape is displayed, the steel ball 17 on the fixed force connecting rope 2 is blocked and cannot pass through, thereby meeting the pilot's need for the switchable activation mode of the life-saving radio. The upper side of the sliding piece 7 can be marked with "←M" (in the direction of the "I" shape) and "→A" (in the direction of the circle) to clarify the movement direction of the sliding piece. The other end surface of the cushion layer 10 has red and green marking lines on both sides (can also be changed to other colors as needed) to indicate that the sliding piece 7 is pushed into place. When the steel ball 17 slides into the shallow groove, the "I" shape or circle of the sliding piece 7 is displayed on the converter 1. In order to facilitate the push and pull of the sliding piece, a structure that is easy to grasp can be set on the edge of the sliding piece as the sliding piece pushing end 23, such as a bent structure, a convex edge with a slot, etc.

[0039] When the pilot pushes the mode to the automatic mode, when the person and the chair are separated, the seat first pulls the life-saving radio start pin connecting ring 19 through the fixed force connecting rope 2 to realize the self-start of the life-saving radio, and then disconnects from the insurance 16, and the person and the chair are separated normally; when the pilot pushes the mode to the manual mode, when the seat pulls the fixed force connecting rope 2 when the person and the chair are separated, the steel ball 17 on the fixed force connecting rope 2 is blocked by the "I" groove on one side of the special-shaped hole, and is directly disconnected from the insurance 16, which does not affect the separation of the person and the chair, and the life-saving radio will not be started. The pilot manually turns on the life-saving radio at an appropriate time according to actual needs to release a distress signal.

[0040] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable technicians familiar with the technical field to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention.
