Impact penetration submerged deep water frozen soil continuous sampling device

Abstract

The invention relates to an impact penetration submerged deep water frozen soil continuous sampling device and belongs to the technical field of deep space exploration. The device comprises a follow-up cable, a rotating shaft, a main shell, an impact penetration type submerging device, a locking mechanism and a sampling mechanism; the rotating shaft is fixedly arranged at the top end in the main shell; the impact penetration type submerging device is vertically arranged in an inner cavity of the main shell in the axial direction; the follow-up cable is wound on the rotating shaft; one end of the follow-up cable is fixed, and the other end of the follow-up cable is fixedly connected with the top end of the impact penetration type submerging device after winding the rotating shaft; the locking mechanism is arranged on the outer wall of the impact penetration type submerging device and extends out of the main shell, so that the impact penetration type submerging device is locked and limited or unlocked and released relative to the main shell; and the sampling mechanism is arranged at the bottom end of the main shell. According to the device of the invention, a tunneling and coring scheme based on an impact penetration submerging driving mechanism is designed, an unmanned autonomous sampling and sample transfer full-flow movement action flow is realized, and the problems of connection of movement actions and system integration are systematically solved.

Description

technical field [0001] The invention belongs to the technical field of deep space detection, and relates to a continuous sampling device for impact penetration submerged deep water frozen soil. Background technique [0002] The scientific task of sampling and detecting water, ice and permafrost in the permanent shadow area of ​​​​the lunar polar region of the fourth phase of my country's lunar exploration project. According to the analysis results of lunar exploration data at home and abroad, the depth range of 0.5-3m in the depth profile of the lunar polar region is the high probability enrichment area of ​​water ice. In order to ensure the probability of obtaining water-containing ice samples, it is required to carry out sampling at a depth of about 1m. Considering that the fourth phase of my country's lunar exploration project is an unmanned lunar exploration project, all scientific exploration must be completed under unmanned conditions, so the sampling plan adopted nee...

Problems solved by technology

The advantage of the drilling scheme is that the drilling energy density is high, and the drilling and sampling of frozen soil can be realized more reliably; the disadvantage is that the external mechanism supporting the drilling tool drilling and sampling is particularly complicated, heavy in weight, large in size, and high in power consumption. There is a certain conflict between the needs of spaceflight
