Problems solved by technology

[0003] The present invention solves the risk that the core soft bag is scratched, worn, or the soft bag or sealing components may be stuck during the sampling work of the lunar exploration project in the prior art. If it is too large, it will cause insufficient power of the motor to lift the core, which will lead to system failure, and the broken position of the sealing cable is not clear, so that the drawstring buckle cannot be sealed reliably, resulting in the leakage of lunar soil samples.

Abstract

The invention discloses a pull rope buckle sealing component for a lunar soil coring soft bag, and relates to the pull rope buckle sealing component for a soft bag. The pull rope buckle sealing component for the lunar soil coring soft bag aims to overcome the risks that a coring soft bag is scratched and worn, and the soft bag or the sealing component is possibly to cause clamping stagnation and the like when sampling work in a lunar exploration program is performed in the prior art, and solve the problems that equipment performance cannot be fully utilized because core lifting force is too low, a system fails because of insufficient motor core lifting force caused by over-high core lifting force, and a lunar soil sample leaks because a pull rope buckle cannot seal reliably due to an undefined sealing pull cable breaking position. The pull rope buckle sealing component for the lunar soil coring soft bag comprises a pulling rope, a coring soft bag, an inner maintaining core pipe, a limiting ring, a protecting sleeve, a fixing pipe and an integrated pulling cable; the integrated pulling cable comprises a second sealing pulling cable, a first sealing pulling cable, limiting pulling rings, and broken ropes; the coring soft bag is arranged on the inner maintaining core pipe in a sleeving manner; the second sealing pulling cable and the first sealing pulling cable are arranged on thecoring soft bag; two broken ropes are arranged on each of the first sealing pulling cable and the second sealing pulling cable. The pull rope buckle sealing component for the lunar soil coring soft bag is used in the field of lunar soil coring.

Description

technical field [0001] The invention relates to a drawstring-fastened sealing assembly for a soft bag, in particular to a drawstring-fastened sealing assembly for a lunar soil coring soft bag. Background technique [0002] The unmanned lunar exploration project is an important milestone in the history of my country's aerospace development. An important part of the lunar exploration project is the sampling work. Because the moon has the characteristics of large temperature changes and uncertain soil structure, how to do it in the mysterious environment of the moon? The task of unmanned drilling, collecting and packaging samples is particularly difficult; for the sampling and detection of lunar soil surface and deep material, drilling and sampling are mainly used as the main operation mode. The current drilling and coring mechanism is mainly composed of drilling unit and coring Due to the randomness of lunar soil particles, some characteristic particles are stuck at the sampling...
