A spring accumulator type flying net retracting device

Abstract

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.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a spring energy storage type flying net closing device, which is used for closing the flying net in the process of capturing non-cooperative target flying nets in space. Background technique [0002] The space flying net capture system is a new type of on-orbit operating system that launches a large-scale flexible net to capture space non-cooperative targets, including main functional components such as the flying net parent satellite, flying net launch system and closing mechanism. The closing mechanism is generally built in the launching mass of the flying net. After the flying net is launched and forms a specific positional relationship with the captured target, the closing mechanism starts to work to complete the closing, thereby preventing the captured target from escaping. It can be seen that the closing mechanism is an important guarantee for the success of the space fl...
