Miniature terrestrial ecological system experimental apparatus capable of operating under microgravity environment

Abstract

The invention belongs to the technical field of aerospace life guarantee and discloses a miniature terrestrial ecological system experimental apparatus capable of operating under a microgravity environment. The miniature terrestrial ecological system experimental apparatus capable of operating under the microgravity environment is mainly used for miniature terrestrial ecological system operation experiment under a weightless environment. The miniature terrestrial ecological system experimental apparatus capable of operating under the microgravity environment mainly comprises a plant area 1, ananimal area 2, a solid waste area 3, a water tank area 4 and an electric control area 5. Plants can be planted in the plant area 1 to generate oxygen for organisms in the animal area 2 and the solidwaste area 3 to use; animals can be raised in the animal area 2; microbiological treatment solid wastes can be inoculated in the solid waste area 3; the nimal area 2 and the solid waste area 3 can both generate carbon dioxide for the plants in the plant area 1 to use; the water tank area 4 can provide water for the plants and can realize system water circulation; the electric control area 5 can monitor and control various physical and chemical indexes and parameters in each sub area in a system; and meanwhile, illumination can be provided for the plants to guarantee the normal operation of theapparatus. The miniature terrestrial ecological system experimental apparatus capable of operating under the microgravity environment has the advantages of simple structure and high automation degree; and the miniature terrestrial ecological system experimental apparatus capable of operating under the microgravity environment can be used for studying the effect of space environment special conditions on an integral terrestrial ecological system and each biological links

Description

technical field [0001] The present invention proposes a miniature terrestrial ecosystem experiment device that can operate in a microgravity environment, and can carry experiments on orbiting aircraft such as spacecraft and space stations. At the same time, it can also realize the independent operation of each biological module to study the parameters of the system. The invention has compact structure, complete partitions, high space utilization rate and high degree of automation, and can study the influence of special conditions of space environment (microgravity, weak magnetic field, long-term low-dose radiation) on the whole terrestrial ecosystem and each biological chain in real time. Background technique [0002] With the rapid development of human spaceflight, the scope of human exploration of extraterrestrial planets continues to expand. The establishment of a lunar base and manned landing on Mars have become the main research tasks at present. In order to realize th...
