Problems solved by technology

[0004] The above-mentioned gas transmission sample scheme and the conventional mechanism of the re-connectable sample channel cannot be realized, and there are no mature products for reference. Therefore, a new re-connectable sample transmission channel scheme needs to be designed to meet the task requirements

Embodiment

[0052] 1) The overall scheme design of the repeatable connection sample transmission channel

[0053]The inner tube 1, the outer tube 4 and the sealing ring 3 form a sealed cavity, and the gas enters the sealed cavity from the gas nozzle 2 to drive the moving tube 8 to move outward. During the outward movement of the moving tube 8, the tension spring 6 is elongated, and the fixed support ring 9 always slides and supports the inner wall of the moving tube 8, and the sliding supporting ring A5 and the sliding supporting ring B7 cooperate with the sliding support on the inner wall of the outer tube 4 until the moving tube 8 is docked with the sample collection container 10, thereby establishing a through channel to realize sample transmission. After the sample is transferred, the air supply is stopped, and the pressure is released in the sealed chamber composed of the inner tube 1, the outer tube 4 and the sealing ring 3, thereby losing the thrust on the moving tube 8, and the mo...

Abstract

A re-connectable sample transmission channel suitable for sampling extraterrestrial celestial bodies. The inner tube, moving tube and outer tube are set sequentially from the inside to the outside; the moving tube can slide along the axis in the cavity formed by the outer wall of the inner tube and the inner wall of the outer tube ; One end of the inner tube is docked with the sample collection container through the guiding structure; one end of the inner tube is fixed with a fixed support ring; the other end of the inner tube is fixedly connected to the sealing ring; a closed cavity is formed between the inner tube, the outer tube and the sealing ring, and the outer There is an air nozzle on the tube, which is used to inflate the airtight chamber through the air nozzle to push the sealing ring and the outer pipe to move axially towards the sample collection container; the tension provided by the tension spring is used to move the outer The tube and sealing ring are pulled back to the original position. The present invention does not use motors, scroll springs and other drive sources with large resource requirements, large volume and weight, but uses the existing gas source for transferring samples of the detector as the drive source, and realizes the sample channel at a small engineering cost The establishment and avoidance of technical problems.

Description

technical field [0001] The invention relates to a repeatable connection sample transmission channel suitable for sampling extraterrestrial celestial bodies, belonging to the technical field of deep space detection. Background technique [0002] Extraterrestrial celestial bodies are an important carrier for humans to understand the origin and evolution of the universe and the solar system, and carry rich scientific information. Therefore, it is of great significance to sample and return extraterrestrial celestial bodies. [0003] After the extraterrestrial object sampling device collects the sample, it needs to transfer the sample to the sample collection container. The use of gas to transfer the sample to the sample collection container through the pipeline avoids the addition of additional sample transfer mechanisms, and the overall resource cost is small, which is a better sample transfer method. However, since there is a sealed door at the entrance of the sample collecti...
