Definitions

  • the present invention relates to a flushing head for a flushing hose to be used in a duct inspection, having a plurality of nozzles distributed along a circumference about a longitudinal axis, which are connected via at least one feed to a flushing head access provided for the arrangement of a flushing hose. Furthermore, the invention relates to a flushing device with a flushing hose provided with a previously described flushing head, in particular a flushing carriage for cleaning the channel.
  • a device which comprises a flushing head according to the preamble of claim 1.
  • This flushing head is guided along with the connected flushing hose via a carrier vehicle provided with a camera along the main channel to the house connection channel and introduced from there via a pivoting arm in the house connection channel.
  • the carrier vehicle is in this case controlled by an associated camera carriage, while the flushing hose with the flushing head is operated by a flushing vehicle.
  • a flushing head which has an asymmetrical arrangement of the nozzles, whereby the front part of the nozzle head along the pipe wall along schieift and is automatically pressed into this upon reaching a A concernedelgkanalausündung. Whether this nozzle can float is not revealed.
  • a nozzle which can be spirally guided along a pipe wall, this rotation being effected by a rotation of the hose.
  • the JP 11114513 A discloses a rinsing nozzle provided with an additional camera head, the nozzle body of which can rotate.
  • DE 196 01 253 A1 is to remove a lying in a channel to be cleaned on the floor rinsing nozzle, which also has a camera.
  • the DE 42 26 336 describes a cleaning device for channels or pipes with a rotary tilting joint to a flushing hose rotatably and tiltably connected nozzle body arranged at the back and directed backwards nozzles for bottom-side advancement.
  • the nozzle for generating a counter to the weight of the flushing head directed and this exceeding force are distributed asymmetrically about the longitudinal axis.
  • the number, size and / or power of the nozzles is distributed asymmetrically. The distribution is such that the thrust exerted by the in-use nozzles is directed against the weight of a normally-located nozzle and results in lifting of the flushing head.
  • the flushing head and optionally the associated hose can be guided alone and lifted through the channel and is independent of a carrier vehicle, over whose arm it is guided in the direction of a channel to be cleaned.
  • the flushing head can be controlled and / or guided, in particular in a direction transverse to its longitudinal direction.
  • the flushing head of the laterally and / or obliquely rearwardly directed nozzles with respect to the longitudinal axis of the flushing head the latter not only receives a preferred direction in the direction of the longitudinal axis of the channel to be cleaned, but also transversely thereto.
  • the flushing head can also be deliberately directed into channels extending transversely from a channel, counter to its longitudinal direction.
  • the nozzles are controllable for this purpose, ie closed and / or controllable, for example, via magnetic or other eg pressure-controllable valves.
  • the flushing head By virtue of the force exerted by the force of the flushing head, which is exerted on the flushing head by the medium during operation, the flushing head can be raised and, in particular, can be lifted over the multiplicity of contaminants on the bottom of a channel, such as paper or fecal residues. It can also be more easily introduced into house connection channels.
  • the flushing head is associated with a joint through which the flushing hose can be attached to the flushing head in an articulated manner.
  • This joint can be arranged in a region of the hose directed toward the flushing head, wherein the hose is in turn connected to a flushing head described above.
  • the rinsing head access is formed by the joint so that the joint is part of the rinsing head and has a preferably flange-shaped region on which the rinsing hose can be fastened.
  • a joint has particular advantages in combination with a rinsing head which has nozzles for generating a counter to the weight of the rinsing head directed and exceeding this force, the nozzles are distributed in particular according to their size and / or number asymmetrically about the longitudinal axis.
  • the influence of the hose weight during operation on the flushing head can be reduced, in particular in such a way that the hose can be introduced at an angle at an angle to the flushing head.
  • the flushing head can be better aligned at the end of the hose in a desired position.
  • the force acting on the flushing head weight of the hose and the water guided in this are not completely excluded, but by the joint, the influence of the force exerted by the hose and the water flowing in this flowing force is minimized to the orientation of the flushing head.
  • the flushing head can thus be better supported in the channel, in particular at its apex or on the walls and is better controllable.
  • At least one downwardly operating nozzle is provided with a larger free inner diameter than an upwardly directed nozzle. That is to say, the impulse which can be exerted on the flushing head by this nozzle against the weight force is greater than the impulse acting in the direction of the weight force, so that in total there is a force against the weight force.
  • This allows the nozzle to lift well.
  • Particularly advantageous is the use of at least two downwardly acting nozzles, which leads to a stabilization of the nozzle. The nozzle then staggers less in the raised state. It is understood that under downwardly acting nozzle quite well understood an obliquely downward / rearward acting nozzle.
  • the flushing head in addition in the direction of the longitudinal axis of the channel pushed, easily in junctions that point up, retract.
  • the flushing head is rotatable so that it can move laterally from the apex of a channel and thereby pushed past a branch or pulled by the water jet.
  • the rotation of a flushing head takes place here via a tube arranged on the flushing head, that is to say it can be effected manually. This is also possible over distances of several tens of meters.
  • the nozzle can also be designed to be controllable in order to be able to specifically move into such a channel.
  • a stabilization of the floating flushing head during operation is also achieved in that the flushing head has both predominantly for levitating the flushing head used nozzles and other propulsion nozzles, these nozzles differ in that the beam directions of levitation and propulsion nozzles occupy different angles with the longitudinal axis.
  • the flushing head preferably has a flushing capacity of 200-400 l / min, more preferably 250 to 350 l / min, even more preferably 300-350 l / min. This provides a good balance between the amount required for levitation of the flushing head and the maximum amount that can be introduced into a domestic connection duct.
