Detailed Description
The invention is described in detail below by way of example with reference to the accompanying drawings.
The invention provides an extraterrestrial celestial body sampling sealed container which is used for in-situ preservation and vacuum sealing of an extraterrestrial celestial body sampling return sample, and avoids the sample from being polluted by atmosphere in the process of returning to the ground. As shown in fig. 1 and 2, the sampling sealed container of the present invention comprises a sealed cover body 1, a sample receiving assembly 2, a flexible door cover 3, an observation porthole 7, a mechanical arm sample container 8, a filter screen 4, a locking assembly 5, a sealed tank body 6 and a sealed rubber ring 9;
one end of the sealing cover body 1 is connected with a peripheral control motor, and the other end of the sealing cover body is connected with the sample accommodating component 2 through screws. The container is equipped with two sets of flexible door closure 3, installs respectively in the sample collection mouth and the arm sample collection mouth of blowing of sample storage assembly 2 through the screw. The screen 4 is installed on the side wall of the sample storage assembly 2 through screws, the observation porthole 7 is fixed on the side wall of the other side of the sample storage assembly 2 through a pressing plate and screws, and the mechanical arm sample container 8 is installed inside the sample storage assembly 2 through the pressing plate and a polytetrafluoroethylene gasket. The locking assembly 5, the sealed tank body 6 and the sealing rubber ring 9 are all in-tank devices, the sealed tank body 6 is fixedly arranged at the mass center position of the returning capsule, the locking assembly 5 is connected with the sealed tank body 6 through screws and flanges, and the sealing rubber ring 9 is vulcanized on the sealed tank body 6.
The observation porthole 7 and the mechanical arm sample container 8 are made of transparent bulletproof glass, the container can be polished by the transparent bulletproof glass, and a peripheral camera or a video camera can observe the air blowing sample in the sample storage assembly 2 and the collection condition of the mechanical arm sample in the mechanical arm sample container 8 through the transparent bulletproof glass; the flexible door cover 3 is made of superelastic memory alloy, and the rest materials are aluminum alloy.
Before sampling, the sealing cover body 1 and the sample receiving assembly 2 (comprising the flexible door cover 3, the observation porthole 7, the mechanical arm sample container 8 and the filter screen 4) are separated from the sealing container 6, the sealing container 6 is positioned in the return cabin, the sealing cover body 1 and the sample receiving assembly 2 are positioned outside the return cabin, and the air-blowing sample sampling pipe is inserted on the sample receiving assembly 2.
