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

Disclosed is a repeatable connection sample conveying channel suitable for extraterrestrial celestial body sampling. An inner pipe, a movable pipe and an outer pipe are sequentially connected in a sleeved manner from inside to outside; the movable pipe can slide along the axis in a cavity formed by the outer wall of the inner pipe and the inner wall of the outer pipe; one end of the inner pipe isin butt joint with a sample collecting container through a guide structure, a fixed supporting ring is fixed to one end of the inner pipe, and the other end of the inner pipe is fixedly connected witha sealing ring; a closed cavity is formed between the inner pipe, the outer pipe and the sealing ring, an air nozzle is arranged on the outer pipe, the closed cavity is inflated through the air nozzle, and the sealing ring and the outer pipe are pushed to move towards the sample collecting container in the axial direction; and tensioning force provided by a tension spring is used for pulling theouter pipe and the sealing ring back to an initial position after air pressure of the closed cavity is relieved. According to the repeatable connection sample conveying channel suitable for extraterrestrial celestial body sampling, a driving source with a high resource demand, a large size and a large weight, such as a motor and a volute spiral spring, is not adopted, an existing gas source, for transferring samples, of a detector is used as a driving source, and the technical problems about sample channel establishment and avoidance are solved at a very low engineering cost.

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...
