Claim 7:
8. A method for a live flaw detection of a multi-bundled conductor splicing sleeve using the live flaw detection system according to claim 1, the method comprising the steps of:
(1) assembling the upper apparatus and the lower apparatus respectively, and fixing the foot stand of the unmanned aerial vehicle of the upper apparatus on the pull rods at the top of the press plate frame of the lower apparatus, wherein the slide tables of the two vertical screw slide table modules of the lower apparatus are in a vertical state;
(2) moving the screw slide block of the horizontal screw slide table module outward with the projection imager to a position close to the two vertical screw slide table modules;
(3) extending the retractable rod of the linear retractable apparatus to cause the two vertical screw slide table modules to rotate outward around the respective first rotation shafts mounted on the two sets of press plates, wherein during a rotation, the two vertical screw slide table modules drive the horizontal screw slide table module and the projection imager to swing to an outer side of upper grooves of the two sets of press plates;
(4) controlling the unmanned aerial vehicle to move to above the upper multi-bundled conductor splicing sleeves, determining a position relationship between an entirety of the live flaw detection system and the multi-bundled conductors through the laser sensor and adjusting a position of the unmanned aerial vehicle to land the unmanned aerial vehicle accurately such that the two sets of press plates all span across the upper multi-bundled conductor splicing sleeves through the upper grooves at bottoms of the two sets of press plates;
(5) controlling the locking motors on the press plate frame to work such that the bracket plates rotate upward to hold and lock the upper multi-bundled conductor splicing sleeves to fix the entirety of the live flaw detection system stably on the upper multi-bundled conductor splicing sleeves;
(6) retracting the retractable rod of the linear retractable apparatus, such that the two vertical screw slide table modules return to the vertical state;
(7) adjusting a position of the projection imager through the two vertical screw slide table modules and the horizontal screw slide table module to cause the projection imager to be located under a first upper multi-bundled conductor splicing sleeve of the upper multi-bundled conductor splicing sleeves;
(8) adjusting an angle of the industrial X-ray machine, to cause an X-ray emitted by the industrial X-ray machine to be projected on the projection imager after passing through the first upper multi-bundled conductor splicing sleeve to complete a detection of a structure of the first upper multi-bundled conductor splicing sleeve;
(9) adjusting a horizontal position of the projection imager through the horizontal screw slide table module such that the projection imager is located under a second upper multi-bundled conductor splicing sleeve of the upper multi-bundled conductor splicing sleeves; adjusting the angle of the industrial X-ray machine to cause the X-ray emitted by the industrial X-ray machine to be projected on the projection imager after passing through the second upper multi-bundled conductor splicing sleeve to complete a detection of a structure of the second upper multi-bundled conductor splicing sleeve, wherein similar processes are performed until a detection of the upper multi-bundled conductor splicing sleeves are completed;
(10) repeating the steps of extending the retractable rod and retracting the retractable rod;
(11) completing a detection of each of lower multi-bundled conductor splicing sleeves of the multi-bundled conductors with reference to the steps of adjusting the position of the projection imager, adjusting the angle of the industrial X-ray machine and adjusting the horizontal position of the projection imager;
(12) repeating the step of extending the retractable rod;
(13) controlling the locking motors on the press plate frame to work reversely, such that the bracket plates rotate downward to unlock the upper and lower multi-bundled conductor splicing sleeves; and
(14) controlling the unmanned aerial vehicle to return, to complete an entire detection process.
