With the technology that the present mankind have, a large amount of samples can not be taken on the earth and analyze, what can do is take back trace sample Returning ball, or directly analyzes it on asteroid.The falcon bird number of Japan was launched in 2003, asteroid 25143 is sampled, first country that successful acquisition sample also successfully returns on asteroid, falcon bird is launched spheroid number after arriving at asteroid surface and to hit the mark object in different location, the object of sampling is reached by the surface rock granule dust etc. splash on asteroid, powder sample is so just inevitably brought to reclaim problem, in addition, in order to study rock and the soil regime of asteroid surface zones of different better, so enable the dust insulation package from different site collection as far as possible, study respectively, result is allowed more to have science and reference significance.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, a kind of retracting device of deep-space asteroid sample collection detector is provided.
The technical solution used in the present invention is: the mechanism of a kind of the automatic recovery sealing, sample insulation package, and it mainly comprises: recovery capsule, sample inlet pipe mouth, encapsulation cylindrical shell, O shape rubber seal, rotation division board, drive motor, linking springs, slide block, spring steel plate and Compress Spring thereof.
Key structural feature is: described rotation division board, encapsulation cylindrical shell, O shape rubber seal, linking springs, slide block, spring steel plate and Compress Spring are all placed in recovery capsule, the lower end of described recovery capsule has notch, one end of sample inlet pipe mouth, through after this notch, communicates with encapsulation cylindrical shell, recovery capsule inwall has cone tank at notch left end place, makes spring steel plate on slide block enter rear automatic clamping wherein, Compress Spring is positioned at recovery capsule low order end, one end of support slipper, the excircle of slide block evenly fixes some spring steel plates, the other end of slide block supports encapsulation cylindrical shell by linking springs, a cylindrical cavity is had in encapsulation cylindrical shell, the latter half of cylindrical cavity evenly has the chamber of three circular sections, rotate division board and be placed in cylindrical cavity, having a cross section is the opening of circular arc, rotate division board to match with encapsulation cylindrical shell, three separate confined spaces can be formed, drive motor is arranged on the bottom of encapsulation cylindrical shell, its output shaft is connected with rotation division board, O shape rubber seal is arranged in the groove of encapsulation cylindrical shell outside.
Beneficial effect of the present invention: under the prerequisite of asteroid surface sputtering sampling, realizes by the specific structural features rotating spacing block and encapsulation cylindrical shell the insulation package that different location gathers grit; By the indoor design of recovery capsule, under the driving of Compress Spring, automatically can complete the sealing action that sampling terminates rear encapsulation cylindrical shell, and the snap-in force of O shape rubber ring is provided by linking springs.The present invention is a kind of compact conformation, and packaging mechanism is reclaimed in the isolation that robotization realizes, and whole action implementation procedure is also simple and reliable.
