Problems solved by technology

Since the actuator of this device is a pyrotechnic cutter, when there are multiple pressing points on the satellite, it is necessary to set up multiple pyrotechnic cutters between the satellite body and accessories, and between components, which increases the duration of the spaceflight. Cost, occupying a lot of space on the star, and the pyrotechnic cutter cable, power supply, etc. will also increase the weight of the unlocking system; and the detonation component is used during separation, the gas impact load generated after detonation is large, and it is easy to generate redundant objects and cause damage to surrounding equipment. Cause adverse effects; when the pyrotechnic cutter at a certain compression point fails, the compression point cannot be effectively released, reducing the reliability of unlocking

Embodiment Construction

[0017] Such as image 3 , Figure 4 As shown, the space linkage compression release mechanism of the present invention consists of a compression cap 201, a compression rod 202, a housing 1, a spring cover 2, a spring 3, a spring support 4, a locking link 5, a U-shaped link 6, Straight connecting rod 7, connecting pin 8, fixed pin 9, guide pin 11, rope connector 12, rope guide ring 13, interlocking rope 14 and high-friction gasket 15 form.

[0018] Such as Figure 8 As shown, the housing 1 is provided with a fixed pin shaft hole 101 , a guide groove 102 , a spring through hole 103 and a connection port 104 for a pressing rod.

[0019] The spring 3 is located between the spring cover 2 and the spring support 4 , and the spring support 4 is fixed on the spring through hole 103 . The locking link 5 has a "<" shape structure, and the two locking links 5 are assembled inside the housing 1 through two fixed pin shafts 9 and distributed symmetrically. The locking link 5 can rotate ...

Abstract

Space linkage pressing the release mechanism, through a rope linkage link mechanism to achieve locking and unlocking the tightening rod.Under the premise of maintaining the unchanged mechanical interface of the original rod type, the lock -up and unlocking the original firework cutter with the rope link mechanism to achieve the unlocking function.The agency overcomes the traditional pressure release agency at each pressure point to use a firework cutter (or other release power sources) to achieve the unlocking function, so it can reduce a large number of spacecraft firework cutters (or other power source unlocking unlockingThe number of devices) reduces costs. At the same time, the agency has a low impact load when unlocked, does not generate excess objects, and can achieve multiple tightening points and unlocking function.

Description

technical field [0001] The invention relates to a space linkage pressing and releasing mechanism which is used to realize the fixed connection between a satellite body and an accessory, and between parts and parts when a spacecraft is launched, and can release constraints according to predetermined instructions after orbiting. Background technique [0002] At present, the bearing unit of the compression release device on the spacecraft mostly uses a compression rod made of titanium alloy, and the compression rod is cut off by a pyrotechnic cutter during release. Use a labor cutter to cut off the compression rod. Such as figure 1 , figure 2 As shown, it is a compression release device widely used on spacecraft at present, which is composed of a compression cap 201, a compression rod 202, a compression seat 203, and a pyrotechnic cutter 204. The pyrotechnic cutter 204 is internally provided with a piston 2041 And cutting device 2042. Its working principle is as follows: t...
