Claim 7:
8. A method for inspection and cleaning of straight hollow cylindrical objects for generating time-stamped cleaning data to monitor the condition of the cylindrical object and to estimate quality and effective service life of the cylindrical object, the method comprising the steps of:
connecting cleaning device to a main control unit and inserting it inside the cylindrical object;
powering ON a drive assembly to drive the cleaning device linearly along the length of the cylindrical object while rotating spirally along a longitudinal axis of the cleaning device thereof and acquiring a plurality of pre-cleaning images of an inner wall of the cylindrical object at plurality of sections travelled by the cleaning device;
simultaneously spraying a pressurized cleaning liquid radially on the inner wall of the cylindrical object;
storing the pre-cleaning images in a memory storage module of a main computer of the main controller unit;
opening a plurality of brush units of a scrubbing unit to press radially to the inner wall of the cylindrical object and linearly reciprocating the scrubbing unit at a high frequency for wet scrubbing of the inner wall of the cylindrical object to remove sludge and sediment;
spraying a pressurized lubricant oil radially on inner wall of the cylindrical object by linearly driving the cleaning device inside the cylindrical object;
opening a plurality of brush units of a wiping unit and a mopping unit, along with lint free stretchable cloth cap, to press radially to the inner wall of the cylindrical object for mopping the sludge and sediment and wiping excess lubricating oil, wherein the mopping and wiping is achieved by a twisted linear motion of the cleaning device;
acquiring a plurality of post-cleaning images of inner wall of the cylindrical object, at plurality of sections travelled by the cleaning device, by driving the cleaning device inside the cylindrical object linearly along the length of cylindrical object while rotating spirally along the longitudinal axis of the cleaning device thereof;
storing the post-cleaning images in the memory storage module of the main computer;
analyzing and processing the pre-cleaning and post cleaning images and deriving the cleaning performance with a central processing module and a graphical processing module of the main computer to detect uncleaned patches;
generating a selective cleaning sequence of scrubbing, mopping and wiping to clean the uncleaned patches; and
generating a report of cleaning operation to provide cleaning status of the cylindrical object and indicating the presence of any surface anomaly on the inner wall of the cylindrical object.
