Parachuting device for recorder recovery

Abstract

The invention relates to recorder recovery in the field of aerospace, specifically to a parachuting device for recorder recovery, which solves the problem of difficult recorder recovery in the field of aerospace and which comprises an accommodating box and a parachute box, wherein the outer wall of a side plate at one side of a parachute box cover is fixed with a clamping block, the outer wall of the side plate at opposite side of the parachute box cover is fixed with a spring with raised lower part; the inner wall of the side plate at one side of a parachute box body is fixed with a main clamping block, the side plate at opposite side of the parachute box body is provided with a slot; an energy accumulator and an initiation control device are arranged below the main clamping block, the free end of a plunger post of the energy accumulator is aligned with the lower part of the spring; the initiation control device comprises a height sensor, a stepping motor and a control single chip machine, a power output shaft of the stepping motor is fixed with a poking sheet for poking a switch for the energy accumulator; a bottom plate of the parachute box is equipped with a compression spring, and a parachute, ropes of which are fixed with the bottom plate of the parachute box and on the top of which a GPS positioning device is fixed, is arranged between the compression spring and the parachute box cover. The parachuting device for recorder recovery has simple and reasonable structure, can effectively protect recorder in the process of recovery, and can offer positioning information after a recorder lands.

Description

technical field [0001] The invention relates to the recovery of recorders in the aerospace field, in particular to parachute equipment for recovery of recorders. Background technique [0002] At present, after a flying object is lifted into the air in the field of aerospace, it is often necessary to recover the recorder that is separated from the flying object or the recorder that fell together with the flying object to read the monitoring data recorded in the recorder, so as to collect the data of the flying object’s launch Parameter information such as trajectory and speed are used for subsequent research and verification of flying objects. For example: the state recorder installed in the rocket propulsion section records the parameter information of the rocket lift-off in real time during the ascension process of the rocket, separates from the rocket together with the propulsion section, and falls from a high altitude. Due to the great fall of the recorder from a high al...
