A kind of maintenance device and application method after removing bacterial plaque on the surface of materials in the cabin of a space station

Abstract

The invention discloses a repair device and a method for using it after removing bacterial plaque on the surface of a material in a space station cabin, and relates to the technical field of cabin inner surface repair, including a liquid storage bag, a sample injector and a brush head; a liquid outlet and an inlet of the liquid storage bag The inlet of the sampler is connected, and the brush head is arranged at the front end of the sampler. The equipment is small and light, easy to operate, and combined with water-based antibacterial and antifungal agents, it can realize the repair of the surface of the material in the cabin after the plaque is removed under microgravity. Negative pressure automatic liquid supply, by pressing / releasing the movable handle, using the pressure change in the volumetric flask, the water-based antibacterial and antifungal agent is automatically injected. The sample injection volume can be adjusted. Select the brush head according to the required coating area and position of the material surface in the space station cabin, and determine the required sample injection volume. Press the movable handle to make the adjustment gear cooperate with the positioning sleeve, and rotate the adjustment gear to adjust the injection volume. sample size. Anti-suckback, with one-way valve design, only one of the two one-way valves is open at the same time, the liquid can only move in one direction, which can prevent the liquid from flowing back.

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
