Definitions

  • the invention relates to a device for cleaning and / or inspection of a flow channel, in particular a sewer, with an insertable into the channel, can be acted upon with high-pressure rinse water flushing hose, which is connected at its front end to a at least with a recoil effect generating jet nozzles provided channel nozzle, which is steerable by rotation about its axis.
  • An arrangement of this kind is for example from the DE 10 2011 120 152 A1 known.
  • a hose receiving means provided for receiving a flushing hose supply and designed as a reel is rotated about an axis parallel to the longitudinal axis of the outflowing flushing hose.
  • the reel is for this purpose mounted by means of a rotary joint at the rear of a carrier vehicle and rotatable by means of a drive device. All of the reel associated supply lines and the flushing water line must be performed centrally through the swivel joint. This proves to be very expensive and prone to failure.
  • a further disadvantage of the known arrangement is that it must then be rotated over its entire length in order to effect a rotation of the nozzle nozzle of this receiving flushing hose, which has an unfavorable effect on the achievable accuracy.
  • the flushing hose acted upon by high-pressure flushing water has a torsion spring property which is small but not completely negligible, so that a certain twisting results with a rotation of the flushing hose with increasing length, which causes a precise rotation of the duct nozzle difficult and therefore can lead to errors in the angle of rotation.
  • the known arrangement therefore proves to be not easy, trouble-free and accurate enough.

  • the two elements of the clutch unit are locked against each other A rotational movement about the Spülschlauchachse is therefore transmitted from the rear hose section on the front hose section.
  • the flushing hose therefore has to be twisted overall for rotation of the duct nozzle, which leads to the above-mentioned disadvantages with regard to construction, accuracy and susceptibility to failure.
  • flushing hose is divided into at least two sections which are interconnected by a high-pressure flushing water coupling unit, which is connected to a flushing hose section housing element and axially movable in this, connected to the other flushing hose section Hollow piston element, wherein the housing member and the hollow piston member are supported by a spring against each other and cooperate via an axial movement into a rotary motion converting transducer means.
  • the flushing hose receiving device can therefore be arranged in an advantageous manner stationary, which greatly simplifies the structure and prevents a susceptibility to interference.
  • Another particular advantage of the measures according to the invention is also to be seen in that the clutch unit according to the invention easily and without major. Expenditure can be retrofitted, so that even existing arrangements for cleaning end inspection of flow channels can be equipped with the device according to the invention for rotating the front Spülschlauchabitess and attached thereto nozzle nozzle, which widens their potential applications and thus overall good economy results.
  • the hollow piston element has a circumferentially cooperating with the housing element head and a stepped neck therethrough, which passes through an associated, the housing-side Spellerschlauchan gleich opposite housing opening and connected with its outside thereof, facing away from the head end with the associated Spellerschlauchabites is.
  • the gradation of the hollow piston element results in an advantageous manner also within the Housing element an annular space in which the spring is placeable.
  • This can therefore be expediently designed as a helical compression spring, which comprises the inner region of the neck of the hollow piston element and is guided thereby, which can have an advantageous effect on the reliability.
  • a further advantageous measure may consist in that the transducer device is designed as a link arrangement, which has a provided on the one hand spiral groove and on the other hand provided, engaging in the spiral groove sliding element. This can be accomplished advantageously larger angle of rotation.
  • a particularly preferable Ausgestattung the above measures may consist in that the housing member are provided with an internal thread and the hollow piston member with an external thread engaging therewith. This measure not only results in a favorable producibility, but also leads advantageously to a reliable mutual engagement and thus to a reliable power transmission.
  • the clutch unit is arranged with a comparatively small distance of preferably 1-3 meters in front of the duct nozzle. This ensures that on the one hand, the mobility of the nozzle nozzle is not restricted by the clutch unit and that on the other hand no significant twisting of the leading from the coupling unit to the nozzle nozzle Spülschlauchabitess takes place.
  • FIG. 1 shows a section of a sewer system with an accessible via a shaft 1 channel 2, in which a high-pressure rinse water acted flushing hose 3 and a charged with induced draft suction hose 4 are introduced.
  • the flushing hose 3 carries at its front end provided with jet nozzles 5 channel nozzle 6. It can be provided forward and backward jet nozzles 5, from which in each case a high pressure water jet 7 emerges during operation.
  • the pressure of the high-pressure rinse water is in the order of 100-150 bar.
  • a forwardly directed beam serves to loosen dirt deposits 8.
  • the rays 7 emerging backwards cause a further loosening of the dirt deposits 8 and a recoil drive of the nozzle nozzle 6 and a flotation of the loosened dirt to the lowered to the sole of the channel 2 end of the suction hose 4 out.
  • the duct nozzle 6 can be provided with a lighting and camera device 9. On a forward emerging beam can also be dispensed with.

  • the lowerable into the channel suction hose 4 runs through a trunk 13 of the boom 12 into the channel.
  • the carrier vehicle here in the form of the sewer cleaning vehicle 11, contains a flushing water tank 15, to which a high-pressure pump 16, which supplies the flushing hose 3 with high-pressure flushing water, is connected on the suction side, which can produce a water pressure of 100-150 bar.
  • the flushing water tank 15 is separated in the example shown by an advantageously evacuated sludge tank 17, in which the suction hose 4 opens with its upper end, about which the extracted from the channel 2 water-dirt mixture is thrown into the sludge tank 17.
  • the duct nozzle 6 has to be rotated about its axis, for example to separate a tree root that has grown into the channel 2, or to channel the duct nozzle 6 into a lateral duct branch 2a, for example in the form of a domestic connection.
  • the channel nozzle 6 is rotated about its axis, that the rearwardly directed, emerging from the jet nozzles 5 arranged asymmetrically to the nozzle jet 7 cause a lateral force, whereby the channel nozzle 6 is directed into the lateral Kanala ownede Trent 2a.
  • the flushing hose 3 is divided into two sections 3a, 3b, which are interconnected by a flushed by flushing water coupling unit 18, by means of which a rotation of the front, the nozzle nozzle 6 supporting portion 3a in response to the pressure of the flushing hose 3 flowing through high-pressure rinse water can be effected.
