Abstract

The invention relates to the cleaning of pipes and allows to increase the cleaning performance of the internal surface of the pipeline. The device, in addition to the group of inclined nozzles 4, also has a group of nozzles 5, the axes of which are perpendicular to the surface of the deposits. Under the influence of vertical jets sediment is intensively destroyed. Rollers 2 have channels in the form of Segner wheels and are Segner movers that allow the device to move during the operation of the nozzles 5. 1 Cp. f-ly, 4 ill.

The invention relates to the cleaning of pipes with devices moving along the pipes from the inside, and can be used in communal households, melioration and other areas of the national economy.

The purpose of the invention is to improve cleaning performance.

Figure 1 shows the device, a longitudinal section; PA figure 2 - section aa in figure 1; on fig.Z - section bb in figure 2; figure 4 - section bb In figure 2.

The device for cleaning the internal surface of the pipeline has a hollow body 1 connected by means of a pressure hose placed on the drum to the pump (not shown).

The housing 1 has support rollers 2. On the housing 1, as on the axis of rotation, a nozzle head 3 is installed, the center of mass of which is offset from the axis of rotation. The nozzle head 3 has a group of inclined nozzles 4 directed toward the displacement of the center of mass, as well as means for moving the device along the pipeline from the inside due to the energy of the working agent jets. Such a tool is rocnik 2, since each of them is a propeller, due to the fact that in its body the channels in the form of segner wheels are in communication with the cavity of the housing 1.

The nozzle head 3 has an additional group of directional displacement, the center of mass of the nozzles 5, the axes of which are perpendicular to the stop; housing, and the device has a spool for communicating the cavity of the orpus, depending on the pressure of the working agent, either with means for moving the device 2 and with an additional group of nozzles 5, or only with a group of inclined nozzles 4. The spool is a hollow cylindrical cup 6 with by-pass holes 7, spring-loaded spring 8 and placed in the cavity of the housing 1 with the possibility of axial movement between the two extreme pollens, in one of which the spool closes the channel 9, and in the other - the channel 10. The axis of the rollers 2 cross with the axis of the housing 1 at a right angle, with each roller 2 having two oppositely directed segner wheels 12 and 13, and the device is equipped with an additional slide valve to communicate the cavity of the housing 1 in the direction of the housing in the pipeline

unidirectional Segner wheels either one or the other direction.

The spool is a ball 14, placed with the possibility of axial movement under the action of the force of its own weight in channel 15 between two extreme positions, in one of which it overlaps channel 16, and in the other - channel 17.

A device for cleaning the internal surface of the pipeline works as follows.

The device is inserted into the pipeline and the pump is turned on. Working fluid

A flexible hose is fed into the vileness of the body. When the pressure is not enough to move the spring-loaded valve 6, the working fluid through the bypass holes

7 and the channels 10 passes to an additional group of vertical nozzles 5 and simultaneously enters the cavity of the body, and from there along one of the channels, for example 16, to the channels 12 of unidirectional Segner wheels. As a result of the expiration of the working agent from the vertical nozzles 5, there is an intensive destruction of the deposits, and the device rises above the deposits and is pressed by the rollers 2 to the upper pipe arch. The operation of the Segner wheels provides the rollers 2 with rotation for moving the device forward. During the cleaning process, it is possible that the housing 1 rotates around its axis. The nozzle head 3 will not change its position relative to the vertical axis, and the valve 14 will block channel 16. In this case, the working fluid will flow through channel 17 to the segner wheels 13 and by changing the direction of rotation of the rollers 2 the direction of movement of the device does not change.

Thus, pre-cleaning takes place, consisting in the destruction of deposits by vertical jets as the device moves forward.

- To conduct final cleaning noBbmiajoT pressure working fluid-. ti to vestchiny sufficient to move the spool 6 to the extreme forward position. At the same time access is slave

whose fluid to the Segner wheels and to the group of vertical nozzles 5 is blocked and access to the inclined nozzles 4 is opened. The jets elapsed from the inclined nozzles 4 wash away the destroyed deposits. The movement of the device along the pipeline is carried out by winding a flexible hose onto the drum. The operation of the proposed device in the final cleaning mode in principle does not differ from the operation of the device of the prototype. In this mode, the device can move forward also under the action of the horizontal component of the reactive force of the inclined jets. Depending on the angle of inclination of the nozzles and the pressure of the working fluid, the rollers 2 can move either along the bottom or along the upper tube arch.

The use of the invention to improve the cleaning performance due to the intensification of the destruction of deposits by vertical jets. The rollers made of Segner wheels in combination with the spool can increase the reliability of the device.
