Description
Technical Field
The invention relates to a sampling device.
Background
Sampling studies on extraterrestrial celestial bodies are the key content of deep space exploration, while extraterrestrial bodies, such as small celestial stars, are typically small in volume and mass, so that their surface gravity is also small. It is very difficult to achieve landing in such an environment with little gravity, and therefore, existing probes mostly use a "one touch and one go" short contact detection mode, which determines that equipment for sampling on such extraterrestrial celestial bodies must be capable of rapid sampling. Meanwhile, the sampling object on the extraterrestrial celestial body has great uncertainty and may be various forms of substances such as powder, broken stone particles and boulders, so that the sampling mode also has excellent adaptability to the sampling object if the success rate of sampling is ensured.
In view of the above problems, various sampling devices exist in the prior art. For example, patent CN102879219B discloses a catapult impact type sampler which adopts the same principle as japanese falcon to sample, and collects the sputtered dust particles generated by shooting catapult balls to impact the surfaces of small planets, thereby realizing short-time sampling. However, this method is random, has a small sampling amount, is not repeatable, and consumes a lot of resources if multiple samples are needed. For another example, CN104034557B discloses a combined drilling and grappling-shovel sampler which can obtain surface and deep samples and can realize repeated and large-scale sampling. However, both the grab shovel and the drill, the sampling method takes a lot of time, and is not suitable for short-time sampling.

Thus, the partition 104 can separate the whole inner cavity into two relatively independent cavities, so as to avoid the mutual interference between the two groups of samples. Meanwhile, the inclined surface design of the separating body 104 forms a flow guide profile along the excitation direction of the row brush, so that the sample can be ensured to enter a designated area along a set path, and the accurate transmission of the sample can be realized.
In use, the sampling device of the present invention requires that the rotational motion and gas excitation of the brush array assembly 202 be initiated in advance before contact with the sample occurs. When the sampling device is contacted with a sample, the sample contacted with the row brush can be automatically excited and conveyed to the area above the nozzle because the row brush is started, and the part of the sample can be excited for the second time under the action of gas excitation, so that the remote high-speed conveyance is realized, and finally the sample enters the recovery container.
In summary, the sampling device of the present invention can collect samples within several seconds, so that the sampling time is short, and a large number of samples can be collected and repeated sampling can be performed for many times, thereby achieving higher sampling efficiency. The device has extremely high adaptability to the sampling object, namely, the device can realize the full sampling of the samples which can be collected, and can also realize effective avoidance of the samples which can not be collected. The device has the advantages of simple and compact structure, high integration, small volume, light weight and high reliability. When the device is used for sampling, only one driving part 3 and one path of gas are needed to be controlled, so that the requirement on resources is less. Of course, the device is also suitable for other occasions with the requirement of short-time contact downsampling in the deep space exploration and civil fields.
