The implementation principle of the steel pipe inner wall self-rotating type purging device in the embodiment of the application is as follows: rotate bracelet 131 hard, bracelet 131 drive ring gear 132 is at the annular groove 14 internal rotation, and ring gear 132 drives a plurality of gears 133 synchronous rotation, and then realizes the synchronous adjustment to a plurality of fan blade 8 angles, uses retaining member 15 to lock ring gear 132 in annular groove 14 at last for a plurality of fan blade 8's inclination is equal the same.
Then the supporting cylinder 1 is stably placed in the steel pipe, air is introduced into the lantern ring 3 through the air inlet valve 4, air in the lantern ring 3 forms high-pressure air flow through the air nozzle 5, and the high-pressure air flow can sweep oxide skin on the inner wall of the steel pipe; meanwhile, gas in the lantern ring 3 forms high-pressure airflow through the nozzle 7, the high-pressure airflow is in contact with the wind bearing surface of the fan blade 8, the fan blade 8 is pushed to move towards the direction far away from the nozzle 7, the fan blades 8 drive the rotating ring 61 to rotate on the sliding cylinder 2, and the rotating ring 61 drives the arc-shaped brush plate 62 to rotationally scrape and sweep the inner wall of the steel pipe.
The power part 18 is started synchronously, the power part 18 drives the sliding barrel 2 to slide on the supporting barrel 1, so that the air nozzle 5 and the arc-shaped brush plate 62 on the sliding barrel 2 can clean all parts of the inner wall of the steel pipe, and the cleaning effect of the self-rotating type blowing device on the inner wall of the steel pipe is improved.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
