Definitions

  • the invention relates to a device for rehabilitation, in particular for cleaning pipes, with a cleaning part that can be connected to a supply part via a connecting pipe, which is comprised of a supply pipe for supplying an inflatable sealing part with a medium, at least in sections, which is between the Supply part and the cleaning part is arranged within the tube.
  • a water-inflatable sealing part is known, which is inserted into the pipe to be cleaned and inflated and seals the inside of the pipe from the environment. If the pipe is completely blocked, a pressure between the blockage and the sealing part, which corresponds to the water pressure, is built up via the cleaning part, which is formed from a pipe section, so that, on the one hand, the blockage can be removed and, on the other hand, contaminated water is not unwanted exits the pipe. With very stubborn dirt or blockages, however, the known cleaning device can no longer be used with a view to success.
  • the known sealing part in the manner of a storage bladder, would turn inside out against its direction of action and release the pipe outlet.
  • the sealing part can also be torn off at the point of the connection transition with the connecting or supply pipe, which leads to the cleaning part or to the sealing part.
  • the use of the known device has its limits, particularly outside the sanitary area, when very high pressures have to be built up to remove contaminants, for example in pipelines.
  • a device for the rehabilitation of pipes in which root-killing foams can be introduced into pipes via the connecting pipe, in order to eliminate any root work that may have occurred.
  • the mentioned connecting pipe is surrounded by the inflatable sealing part, which remains in its inflated state at the pipe entrance, whereas for the supply of the root-killing foam, the connecting pipe is guided from the sealing part to the respective location within the pipe to be treated.
  • a feed plug is embedded in the end of the sealing part, which causes sealing problems.
  • This known device is not very suitable for cleaning pipes, for example in the form of blockages.
  • the invention has for its object to provide a device for rehabilitation, in particular for cleaning pipes, which does not have the disadvantages described and which can be used in a variety of ways, and therefore not needs to be limited to use in the sanitary area.
  • This object is achieved by a device having the features of claim 1.
  • the entire sealing part comprises the supply pipe radially, that the sealing part is fixed with its two ends to the supply pipe and that the supply pipe has radially arranged openings that open into the interior of the sealing part Even at high pressures, the sealing part securely comes into contact with the inner wall of the pipe and cannot come off, especially not turn it inside out. A secure seal is therefore guaranteed in every operating state. Since the sealing part is firmly connected to the supply pipe, it is moved together with it within the pipe and inflated only at the point of contamination or blockage. Consequently, there is no friction between the sealing part and the pipe or with the supply or connecting pipe, so that low-wear operation is ensured.
  • water, compressed air and other cleaning media, fungicides, root-killing foams or renovation material, such as pipe cladding materials to be sprayed on can be fed into the interior of the pipe, depending on the intended use, via the cleaning part.
  • the sealing part can be, for example Introduce harmful media into the pipe from the supply part via the connecting pipe, whereas the sealing part can be supplied with an inflating medium, such as nitrogen gas, from the supply pipe for an inflation process.
  • the device according to the invention can also be used in supply lines, for example in pipelines.
  • a medical application within vascular systems is also conceivable.
  • the device according to the invention could or the like by means of a catheter in the respective bloodstream to remove cholesterol deposits. be used.
  • the cleaning and / or swelling medium to be supplied in each case can also be supplied by the supply part under high pressure, provided that the supply part has the necessary pressure-increasing devices for this.
  • the pressure for the inflatable sealing part must also be increased in order to prevent the cleaning medium with the dirt particles from escaping into the environment in an undesired manner.
  • the cleaning part has a spherical cleaning head which is provided with passages distributed over the ball surface. It is preferably provided here that the passages run along lines that radiate from the center of the spherical cleaning head. Because of this arrangement, treatments can be carried out specifically with the cleaning part inside the tube. To increase the pressure, the passages can be provided with nozzle-like inserts.
  • the sealing part is formed from an elastically flexible bead-like ring, in particular from rubber material. Because of this design, pipes which are not circular in cross-section, for example pipes with a square cross-section, can also be easily treated, in particular cleaned.
  • the elastically resilient ring not only adapts to different pipe geometries, but also compensates for surface roughness within the pipe and can create a larger width on the inner circumference of the pipe, which results in an improved seal.
  • the sealing part when the sealing part is inflated, the ring is deformed and inflated from the center towards the two ends thereof, so that a good sealing effect is achieved from the beginning and, moreover, a high sealing surface is available.
  • the supply pipe is sleeve-like and is sealingly connected to the connecting pipe to form a chamber at the end. This achieves a compact construction of the cleaning device according to the invention.
  • a return pipe is arranged between the sleeve-like pipe section and the connecting pipe, which can be connected to a disposal device and which has a connecting opening which opens into the open between the cleaning part and the sealing part.
  • the medium supplied via this pipe can be removed from the pipe together with the removed dirt particles via the return pipe.
  • the contaminated cleaning medium can then be delivered to a disposal device which preferably filters the contaminants out of the cleaning medium, which in turn can then be returned to the cleaning part via the connecting pipe.
  • a closed circuit for the cleaning medium can be achieved in this way.
  • the disposal device can also consist of the continuation of the pipe or another pipe into which the contaminated cleaning medium can be discharged.
  • the connecting pipe and the supply pipe are connected to the supply part, which has at least one pressure accumulator for the storage of fluid or gas.
  • the device can be designed as a mobile maintenance unit which can be operated directly via the supply part without further connections to external supply devices.
  • At least parts of the connecting, supply and return pipe are flexible.
  • the device can then be used without difficulty in pipes with a large number of curved areas.
  • the tube 10 has a circular diameter. To remove contamination or blockage (not shown) within this tube 10, the cleaning device has been inserted into the tube 10 at a suitable location (not shown).
  • the device has a cleaning part 12 which is connected to a supply part (not shown) via a connecting pipe 14 which is only partially shown in the figure.
  • the device also has an inflatable sealing part 16, which has a predeterminable volume occupies and which is arranged between the supply part (not shown) and the cleaning part 12 within the tube 10.
  • the cleaning part 12 has a spherical cleaning head 18, which is provided with passages 20 in the form of bores, the cleaning head being connected to the connecting pipe 14.
  • the passages 20 are uniformly distributed at predeterminable distances from one another over the circumferential surface of the cleaning head 18.
  • the sealing part 16 is formed from an elastically resilient ring 22 made of a suitable rubber material. This ring 22 can be filled with nitrogen gas via a supply pipe 26.
  • the supply pipe 26 is sleeve-shaped and has one end connected to a supply line 24, which is part of the supply pipe.
  • the pipe section 26 is penetrated by the connecting pipe 14 to form a chamber 28 and is sealingly connected to the end thereof by means of sealing means 29.
  • the ring 22 is in turn sealingly connected to the outer circumference of the sleeve-like tube section 26, which has passages 30 in the form of radially arranged bores for establishing a connection between the ring volume and the chamber volume.
  • two sleeve-shaped clamps 32 are provided which grip around the ends of the ring 22.
  • the connecting pipe 14 and the supply pipe 26 are connected to the supply part (not shown), each of which has a pressure accumulator for storing a cleaning medium or nitrogen gas.
  • the direction of transport of the gas within the mentioned supply line 24 is indicated by an arrow in the figure.
  • An adjustable check valve 34 ensures that the pressure within the bubble-like sealing part 16 is a predeterminable variable, that could damage the rubber or pipe 10 when it reaches its burst pressure.
  • a further controllable valve 35 ensures that the gas once introduced into the ring 22 cannot inadvertently flow back to the accumulator.
  • At least parts of the connecting pipe 14 and the supply pipe 26 in the form of the supply line 24 are flexible in order to be able to follow pipe curvatures of any kind (not shown).
  • the cleaning and renovation device is preferably advanced within the pipe 10 via the connecting pipe 14, which is designed to be flexibly developed from a hose drum.
  • the sealing part 16 is kept essentially pressureless, so that when it collapses, it cannot rub in a damaging manner along the inner circumference of the tube 10.
  • the cleaning head 18 comes into contact with contamination which adversely affects the line cross section of the tube 10, which is noticeable to the operator if the device cannot be pushed further into the tube 10 via the connecting tube 14, a cleaning process is triggered.
  • the supply line 24 is pressurized with gas, which leads to an expansion of the ring-like sealing part 16 via the supply pipe 26.
  • the pumping up or filling of the annular chamber volume with gas is continued until the sealing part 16 is in sealing contact with the inner circumference of the tube 10.
  • a safe, sealing system can be produced by means of an appropriate pressure measuring device (not shown), which detects the pressure increase within the annular chamber.
  • the cleaning medium in the simplest case water, is then passed into the interior of the pipe 10 via the connecting pipe 14 and the passages 20 of the cleaning head 12. The water particles flowing out of the nozzle-like passages 20 dissolve the pollution and thus remove these or pipe blockages.
  • the cleaning part 12 can be moved longitudinally, wherein the cleaning head 18 can be mechanically moved back and forth by means of the connecting pipe 14 with the pipe section 26 held at rest, the position of which is determined by the inflated ring 22 .
  • the cleaning head 18 can be mechanically moved back and forth by means of the connecting pipe 14 with the pipe section 26 held at rest, the position of which is determined by the inflated ring 22 .
  • a negative pressure can be generated via the supply part within the connecting pipe 14 and the cleaning medium with the dissolved dirt particles can be sucked out of the pipe 10. Subsequently, the pressure within the sealing part 16 is reduced, so that the ring 22 collapses and can be taken out of the pipe 10 with the cleaning device or continued to the next contamination or blockage point.
  • the second embodiment of the cleaning device shown in FIG. 2 corresponds essentially to the first embodiment, so that only the differences between the two embodiments are discussed below. Corresponding parts of the two embodiments are reproduced with the same, but for the second embodiment, each with 100 increased reference numerals.
