Self-pressurization space spraying equipment

Abstract

The invention discloses self-pressurization space spraying equipment. The self-pressurization space spraying equipment comprises a drive component, a gas generation source and a spraying component, wherein the drive component comprises a cavity structure for storing liquid material to be sprayed and a piston held in the cavity structure and in contact with the liquid material; the gas generation source comprises a gas generation source body structure connected with the drive component, gas production medicament held in the gas generation source body mechanism, and a push piston for generating high-pressure gas; the spraying component comprises a rotational flow cavity connected with the cavity structure and a rotational flow core arranged in the rotational flow cavity. The self-pressurization space spraying equipment has advantages that pressure needed for liquid spraying is automatically generated by the spraying equipment, and the self-pressurization space spraying equipment only needs the outside to provide an electric initiating signal and does not need the outside to supply pressure and electricity. Under a vacuum condition, the spray liquid material can be atomized completely to be uniformly sprayed to the target surface. When being used in the space, surface treatment for satellite surface equipment is realized through spraying the liquid material so as to improve the surface coating performance thereof; the self-pressurization space spraying equipment can be used for the on-orbit assembly, on-orbit construction and on-orbit lifetime extension of a spacecraft.

Description

technical field [0001] The invention relates to the field of space vehicle equipment, in particular to a self-pressurized space spraying equipment. Background technique [0002] With the development of satellite on-orbit service technology, on-orbit assembly and on-orbit construction of satellites will gradually become a reality. On-orbit assembly and on-orbit construction of the spacecraft have temperature control requirements for the star surface. At the same time, due to the harsh space environment, the spacecraft also needs to carry out necessary surface treatment to achieve environmental protection. All of these require uniform spraying of specific thermal control materials and environmental protection materials on the star surface, so that the star surface has corresponding thermal control and environmental protection functions. [0003] Taking the thermal control of star surfaces as an example, the thermal control coating is one of the main temperature control method...
