The invention provides a spring accumulator type flying net retracting device which belongs to the technical field of
aerospace. The device comprises a series type
clockwork energy storage mechanism,a
rope pulley collecting mechanism, a synchronous gear mechanism, a trigger
locking mechanism, a shell, a
control circuit, and the like. The series type
clockwork energy storage mechanism includes a spring shaft, a spring and a middle wheel. The
rope pulley collecting mechanism includes a
rope collecting outlet guide plate, rope pulleys and a spindle. The synchronous gear mechanism comprises a
bevel gear carrier, a large
bevel gear and a small
bevel gear. The trig and
locking mechanism comprises a spring box, a clamping block, a clamping cover, a push-pull
electromagnet and a return spring. When the upper string is wound, the
electromagnet is not energized, the clamping block restricts the rotation of the rope pulleys, loosens the development bar locking screw, and completes the manual winding. The
control circuit board energizes the
electromagnet, the clamping block retracts, and the rope pulleys rotate to take up the rope under the
spring force of the spring, so as to trigger the rope
pulley. The two rope pulleys are synchronously reversed to realize take-up. Locking is performed after take-up is completed, take-up is finished, the clamping block is reset and the rope pulleys arere-locked.
