Repairing device applied after removal of bacterial plaques on surface of material in cabin of space station and application method

Abstract

The invention discloses a repairing device applied after removal of bacterial plaques on the surface of a material in a cabin of a space station and an application method, and relates to the technical field of cabin inner surface repairing. The repairing device comprises a liquid storage bag, a sample injector and a brush head, wherein a liquid outlet of the liquid storage bag is communicated with an inlet of the sample injector; and the brush head is arranged at the front end of the sample injector. The equipment is small and light, is simple to operate, is matched with a water-based antibacterial and mildew-proof agent, and can be used for repairing after removal of the bacterial plaques on the surface of the material in the cabin under microgravity. Negative-pressure automatic liquid supply is realized according to the following manner: a movable handle is pressed / loosened, and the water-based antibacterial and mildew-proof agent is automatically injected by utilizing the pressure change in a volumetric flask. The adjustability of the sample injection amount is realized according to the following manner: the brush head is selected according to the required coating area and the required position of the surface of the material in the cabin of the space station, the required sample injection amount is determined, the movable handle is pressed to enable an adjusting gear to be matched with a positioning sleeve, and the sample injection amount can be adjusted by rotating the adjusting gear. The suck-back prevention function is realized according to the following manner: the design of one-way valves is adopted, only one of the two one-way valves is opened at the same time, liquid can only move in the single direction, and liquid backflow can be prevented.

Description

technical field [0001] The invention relates to the technical field of cabin interior surface repair, in particular to a repair device and a method for using it after removing bacterial plaque on the surface of materials in a space station cabin. Background technique [0002] The space station provides a suitable living environment for astronauts to stay for a long time, and also provides favorable conditions for the growth and reproduction of microorganisms. Among them, pathogenic microorganisms will affect the health of astronauts; fungi and molds will corrode and degrade various equipment and materials in the space station, thereby affecting the normal use of precision instruments and equipment, and in severe cases, the entire platform of the space station will be at risk of paralysis. [0003] In the event of microbial contamination, wet wipes or cotton swabs are generally used internationally to remove microbial plaques on the surface of materials. However, the stabili...

Problems solved by technology

Since this patent uses chemical oxidation solution and UV-cured coating to complete the surface repair of the material in the cabin twice, it needs to complete two times of liquid inflow and outflow to smear the surface. Turn on the fan and ultraviolet lamp to dry the surface, the operation process is relatively cumbersome, and it is not convenient for astronauts to operate in microgravity
