FIELD: machine building.
SUBSTANCE: invention relates to the category of professional household equipment intended for cleaning of areas from unnecessary objects or materials. Automated self-contained cleaning machine comprises engine, cleaning agent with mechanical destructive effect, collector of treated contaminants and storage container for liquid nitrogen, connected with unit for its application and distribution on surface. Liquid nitrogen storage container is made in the form of a Dewar flask, and connected to it unit for its application and distribution on surface is made in form of cryodestructor, supplying liquid nitrogen to a certain and limited area of surface with contamination by means of controlled subsystem, consisting of an expandable hose, on the end of which a positionable working element with a side wall is installed, which prevents leakage of liquid nitrogen. Cleaning agent having a mechanical destructive effect on the contamination detected and frozen as per incoming signal is made in the form of a needle baffle driven by means of a compressor. Collected contaminants collector is made in form of complex controlled system consisting of suction device with trapping chamber, at the input of which a rotating brush is installed, and at the outlet there is a container for temporary storage of incoming crumbled contaminants with the catching chamber. Machine is equipped with photodetectors, which identify contamination by means of surface heterogeneity, information on parameters of which enter information-analytical system of machine computer controlling operation, made with possibility of generation and sending, taking into account in advance the data on technical parameters of the machine, optimal control signals, activating, deactivating and controlling production processes related to detection of pollution and its elimination from the surface.
EFFECT: invention provides higher efficiency and quality of operation.
