Device for cleaning the inside of sewer or pipe sections

The present innovation relates to a device for the internal cleaning of channel or pipe sections with a drivable cleaning tool as well as a support device for supporting the device in the channel or pipe section to be cleaned.

The aim of the present innovation is to create a device of the generic type that enables optimal and thorough cleaning of channel or pipe sections with the simplest possible drive of the cleaning tool.

This task is now solved by the fact that the

ff cleaning tool consists of a milling disk with both face-mounted milling cutters and radially arranged edge knives, whereby the face-mounted milling cutters completely cover the face, the edge knives are radially adjustable and the milling disk can be driven by means of a turbine thread that can be pressurized with water. i ^;

A device designed in this way enables thorough and perfect cleaning even of heavily soiled sewer or pipe sections, since the cleaning tool is not only able to clean the sewer or pipe sections, but also to grind off any impurities that have accumulated in the sewer or pipe section. The drive of the cleaning tool by means of a turbine wheel that can be pressurized with water ultimately represents the simplest and most practical form for the intended use.

Further features of the innovation are the subject of subclaims.

The accompanying drawings show an embodiment of the innovation, which is described in more detail below.

The device for cleaning the inside of channel or pipe sections, shown in its entirety in Figure 1 and provided with the reference number 10, is equipped with a cleaning tool 11 which can be driven by a turbine wheel 12 which can be operated with pressurized water.

The pressurized water is supplied via a central pressurized water bore 13. This central pressurized water bore 13 opens into one or more radially extending distributor bores 14, whose outlet bores 15, which again run axially to the entire device 10, are directed towards the turbine wheel 12. Centrifugally operated jet deflectors 16 are arranged between the outlet opening 15 and the turbine wheel 12, which extend radially when a predetermined speed is reached or exceeded and prevent further pressurized water from being applied to the turbine wheel 12.

The entire, centrally constructed device 10 is provided with adjustable rollers 17 and also adjustable clamping cylinders 18. By means of the adjustable clamping cylinders 18, the rear end area of the entire device 10 can be fixed in a channel or pipe section 19 to be cleaned, while the adjustable rollers 17 serve to center the part of the device carrying the cleaning tool 11 within the channel or pipe section 10 to be cleaned. This front area can be used independently of the clampable, rear

Section 20 can be moved axially ₍ and by a drive device 21 consisting of pressure cylinders) whose pressure medium supply can be regulated by throttles 23 arranged in the supply lines 22. The throttles 23 make it possible to regulate the feed speed.

Switching options of the throttles 23 can also be switched to a rapid motion for moving the movable part of the device 10 in or out*

In the central area of the cleaning tool II there is a television camera 24, by means of which the channel or pipe section 19 to be cleaned and the progress of the cleaning work can be observed*

The necessary cables 25 leading to the television camera 24 are designed in the form of converted lines, which is shown particularly clearly in Figure 5. These lines 25 are supplied by sealed piston rods.

The cleaning tool 11 is, as Figures 1 and 2 make very clear, equipped with milling cutters 26 in the area of its front surface, which cover the entire front surface of the tool 11. Figure 2 makes this particularly clear.

Furthermore, the cleaning tool 11 has radially extending edge blades 27, which are also adjustable in the radial direction. An automatic radial adjustment option by centrifugal force actuation against the effect of a spring 28 is preferred.

The cleaning tool 11 is provided in its central area with several through holes 29, which

an annular zone. This zone corresponds approximately to the course of the outlet openings 15 through which the pressurized water is directed to the turbine wheel 12. The pressurized water, which is required to drive the cleaning tool 11, can thus pass axially through the cleaning tool 11.

On its outer edge, the cleaning tool is equipped with slots 30 through which the pressurized water can be pumped back, so that the pressurized water not only serves to drive the cleaning tool, but also to transport away milled-out solids.

The course of the pressurized water for the flushing purpose explained above is symbolically indicated in Figure 1 by the dash-dotted line A.

The device according to the innovation can be inserted into the channel or pipe section to be cleaned using the so-called pilgrim step method, with great advantage.

A further advantage of the new device is that the counterforces to the cutting forces are absorbed by the inertia of the rotating milling disk and do not have to be introduced into the pipe or channel wall via complex brackets.
