Core and rod replacing mechanism for multi-core and multi-rod deep lunar soil sampler

Abstract

The invention discloses a core and rod replacing mechanism for a multi-core and multi-rod deep lunar soil sampler and belongs to the field of space resource detection. The core and rod replacing mechanism comprises a drilling rod fixing component, a core-pulling pipe fixing and separating component and a driving component, wherein the drilling rod fixing component comprises a drilling rod disk, a drilling rod disk rotating shaft, a barrel-shaped drilling rod clamp, a drilling rod disk positioning grating and a drilling rod disk electromagnetic locking mechanism; the core-pulling pipe fixing and separating component comprises a core-pulling pipe disk, a core-pulling pipe disk rotating shaft, a core-pulling pipe disk electromagnetic locking mechanism, a sample table bracket, a core-pulling pipe disk positioning grating, a lander acting component and a sample table separating dragging plate; the driving component comprises a gear box bracket, a gear box shell, a drilling rod motion driving shaft, a spring, a transitional joint, a drilling rod disk driving shaft, a core-pulling pipe disk driving shaft, a core-pulling pipe disk driving gear group and a drilling rod disk driving gear group. The core and rod replacing mechanism has the advantages that multi-core and multi-rod sampling is realized, frequent large-scale sampling is achieved, rod and core replacement is precise and flexible, and only collected samples can be recycled to reduce the weight of a returning capsule.

Description

technical field [0001] The invention belongs to the technical field of space resource detection, and in particular relates to a core-changing and rod-changing positioning mechanism of a multi-core multi-rod deep lunar soil sampler. Background technique [0002] The moon is the closest celestial body to the earth, and has always been the first choice for human observation and research. The surface of the moon is covered by lunar soil, which is the basic entry point for human beings to understand the composition of the moon. The analysis and research of lunar soil is of great significance, and it has already become an international hot spot. At present, countries or organizations such as the United States, Russia, the European Space Agency, Japan, India, and China have all launched or are actively carrying out lunar exploration programs. According to my country's lunar exploration plan, the lunar exploration project is divided into three strategic stages of "circling", "falli...

Problems solved by technology

Due to the requirements of the working characteristics of the drill pipe, it is relatively thick and heavy, so the ratio of the sampling volume of the increased sampler to the increased weight of the sampler is small, so the cost of increasing the sampling volume is high

[0006] Second, the return weight of the sampler is large

After the sampler finishes sampling, only the lunar soil itself has actual scientific research value, and if the return capsule brings back the bulky sampler, it will inevitably increase the weight of the return capsule, greatly increasing the burden and cost of the return, and the energy utilization rate.
