Claims (12)

1. The hydromechanical method of cleaning the inner surface of the pipe mainly from solid deposits, including entering into the cleaned cavity of the cleaning element, supplying liquid, bringing the cleaning element into rotation, moving it into the pipe cavity with destruction and separation of solid deposits from the pipe surface, their removal from the cleaning zone characterized in that in order to ensure cleaning of pipes of small diameter, curved pipes, as well as pipes completely clogged with solid deposits, the liquid is fed into the inner cavity of the treatment element nta under pressure, the rotation of the cleaning element around its axis is carried out in the direction opposite to the direction of cutting the teeth and at a speed of at least 100 rpm, and each tooth, backed up along an Archimedean spiral, moves along a helical, single or multiple path, and each subsequent the tooth follows the groove formed by the previous tooth tangentially with its lateral edges, displaces and chops off the hard deposits, forming a stepped surface until the deposits are completely removed, completed by a bead cut into cili core of the cleaning element. 2. The hydromechanical cleaning method according to claim 1, characterized in that the liquid is supplied under a pressure of 2 to 8 kgf / cm ² . 3. A hydromechanical device for cleaning the inner surface of the pipes mainly from solid deposits, comprising a body in the form of a body of revolution, in front of which there is a cleaning element with channels for supplying liquid, and the tail part is connected to the rotational drive of the body, characterized in that to ensure cleaning pipes of small diameter, curved pipes, as well as pipes completely clogged with solid deposits, in it the treatment element is made in the form of a truncated cone on the forming surface of which the tooth is cut with the value at a higher zatylovaniya pen width than the magnitude of lift per tooth, the value of the selected conditions zatylovaniya

where K is the amount of backing across the width of the pen (with a groove);
P is the pitch of the screw thread;
φ is the angle of inclination of the cone of the working part of the treatment element;
Z is the number of feathers of the treatment element (with grooves),
while the teeth on adjacent feathers are staggered relative to each other, the feathers are separated by grooves to which channels for supplying fluid are connected, and a cylindrical girdle is made behind the last tooth.  4. The hydromechanical cleaning device according to claim 3, characterized in that the width of the cylindrical belt is made larger than the screw cutting step, and the diameter of the cylindrical belt is chosen equal to the diameter of the larger base of the truncated cone of the cleaning element.  5. The hydromechanical cleaning device according to claim 4, characterized in that the bead is made on a cylindrical girdle with a rectangular profile, and its step is selected more than the step of the teeth of the treatment element.  6. The hydromechanical cleaning device according to claim 4, characterized in that the bead is made on a cylindrical girdle with a trapezoidal profile, and its step is selected greater than the step of the teeth of the treatment element.  7. The hydromechanical cleaning device according to claim 3, characterized in that for cleaning pipes partially clogged with solid deposits, the direction of cutting the bead on the cylindrical belt of the cleaning element is opposite to the direction of cutting the teeth on the cleaning element.  8. The hydromechanical cleaning device according to claim 3, characterized in that for cleaning pipes completely clogged with deposits, the direction of cutting the bead on the cylindrical belt of the treatment element is similar to the direction of cutting the teeth on the treatment element.  9. The hydromechanical cleaning device according to claim 3, characterized in that in order to equalize the load on the working part of the cleaning element by preliminarily destroying the middle zone of the deposits, a pyramid is made at the end of the smaller base of the truncated cone of the cleaning element, on the lateral surfaces of which there are grooves, which are a continuation grooves of the treatment element.  10. The hydromechanical cleaning device according to claim 3, characterized in that for aligning the load on the working part of the cleaning element by pre-breaking the middle zone of deposits in the end face of the smaller base of the truncated cone of the cleaning element, a groove is made in which a plate with cutting edges made rigidly is fixed similar to the cutting edges of a pen drill.  11. The hydromechanical cleaning device according to claim 3, characterized in that the cutting of the teeth on the forming surface of the cleaning element is made one or multiple.  12. The hydromechanical cleaning device according to claim 3, characterized in that the housing, the cleaning element and the tail part are made in one piece.
