Abstract

The invention provides an automatic soft bag sealing device for drilling and coring. The automatic soft bag sealing device comprises a rotating drill rod, a coring pipe and a soft bag. The coring pipe is arranged in the rotating drill rod and coaxially arranged with the same, the soft bag is hung in the coring pipe, and the lower end of the soft bag is fixed at the lower end of the coring pipe. A circular groove is circumferentially formed in the inner wall of the coring pipe in the direction that the soft bag is close to an opening. A memory alloy clamping ring is arranged in the groove. A thermostatic heater is arranged at the top end of the rotating drill rod, and is electrically connected with the outer side of the memory alloy clamping ring through a lead. The automatic soft bag sealing device for drilling and coring is used for sealing the soft bag directly by the aid of mechanical effect of high-temperature memory alloy in the sealing process after lunar soil collection in an agravic environment is finished, and has the advantages of high reliability, light weight, simple structure, convenience in operation and the like.

Description

technical field [0001] The invention belongs to a sealing technology for soil collection under the state of weightlessness in spaceflight, in particular to an automatic sealing device for soft bags used for drilling and coring. Background technique [0002] There are abundant mineral deposits on the moon, such as titanium, silicon, aluminum, iron and helium-3, among which helium-3 is the most promising new energy source for human beings in the future. Certain rare metal elements on the moon can be used more in military affairs. Therefore, sampling and research on lunar soil is the need of the times and is of great significance. The third phase of my country's lunar exploration project plans to launch a probe to sample the lunar surface and return it around 2017. The lunar soil sampling and coring device is an indispensable and important link in the lunar exploration work. How to realize the acquisition, collection, packaging, etc. of lunar soil in the complex space environm...
