MECHANIZED MACHINE FOR DRAIN PIPES CLEANING Russian patent published in 2017 - IPC E03F9/00 B08B9/02 

FIELD: construction.

SUBSTANCE: machine, according to the first implementation version, includes the cable, the motor unit which is in mechanical communication with the cable and made with the possibility of rotating the cable along the longitudinal cable axis. The motor unit comprises the motor and the motor control device. The motor control device is made with the possibility to transform alternating current into direct current, wherein the motor control device transmits direct current to the motor. The machine additionally comprises the casing adapted for accommodating the motor unit, and the rotation speed control device communicating with the motor unit made with the possibility of varying the operating frequency of motor rotation in the range of operating rotation frequencies. According to the second implementation version, of the machine comprises the frame assembly, the housing accommodating the cable, the cable, the electric motor mounted on the frame assembly. The machine according to the third implementation version comprises the frame assembly comprising several long tubular elements, which comprise the first and the second bottom supporting elements, the angular loop element extending between the first and the second bottom supporting elements, the vertical loop element, the vertical mounting plate attached to the vertical loop element. The vertical mounting plate comprises the opening and the upper supporting element comprising the fixed end and the free end. The machine additionally comprises the drive shaft extending through the opening in the vertical mounting plate, the cable comprising an actuating end, which must be inserted into the drain, the drum mounted rotatably on the drive shaft, the motor and the control device of the rotation frequency made with the possibility to determine the current operating frequency of the motor rotation.

EFFECT: increased efficiency and safety in the removal of obstacles from a sewer or a drain.
