Description

Flushing head and flushing device

The present invention relates to a flushing head for a flushing hose to be used in a duct inspection, comprising 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.

When cleaning the channel, the house connection ducts, which are, for example, 20 cm in diameter, must increasingly be inspected and cleaned. For this purpose, a device is known in the prior art according to DE 102005023024 A1, which comprises a flushing head according to the preamble of claim 1. This rinsing head is guided along with the connected rinsing hose via a carrier vehicle provided with a camera along the main channel to the house connection channel and from there via a

Swivel arm introduced into 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.

CONFIRMATION COPY It is an object of the present invention to minimize the need for the purification of domestic water connections and channels technical effort.

The object is achieved by an article according to claim 1 and by an article according to claim 11.

According to the invention, it is provided that the nozzle are distributed asymmetrically about the longitudinal axis in order to produce a force directed against the weight of the flushing head and exceeding it. In particular, 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. In this way, 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. As a result of the forces exerted on the flushing head by 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. As a result, the flushing head can also be deliberately directed into channels extending transversely from a channel, counter to its longitudinal direction. Preferably, the nozzles are controllable for this purpose, ie closed and / or controllable, for example, via magnetic or other eg pressure-controllable valves. 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, such as paper or fecal residues, located at the bottom of a channel. It can also be more easily introduced into house connection channels.

Advantageously, when nozzles are regularly distributed around a longitudinal axis corresponding, for example, to the longitudinal axis of the flushing hose connected to the flushing head, 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.

In particular, in an embodiment in which the force exerted by the counter to the weight of the rinsing head nozzles force is so great that the rinsing head is supported in a vertical lifting at the apex of a channel, the rinsing head, in addition in the direction of the longitudinal axis of Ka nals is pushed easily in junctions, which point upwards, retract. In order to avoid a non-desired branch, 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.

Preferably, the rotation of a flushing head in this case takes place via a hose arranged on the flushing head, so it can be effected manually. This is also possible over distances of several tens of meters. In addition, 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. Furthermore, an embodiment of a flushing head is advantageous, in which this has at least one and in particular upper-side guide surface, which is provided to support the guidance of the flushing head at the apex or a wall of a channel. This may be, for example, an extended contact surface, ie, the part of the flushing head having the guide is designed in such a way that the flushing head can lean against it about the duct wall approximately parallel or slightly obliquely. The guide surface is preferably a plane or slightly rounded surface, which stands out from the further outer contour of the flushing head and, for example, characterized by flattening of the flushing head on one side. The guide surface serves as a system, via which a floating flushing head can be supported on a channel wall and thereby leads to an alignment of the flushing head in the channel.

Preferably, the guide surface here is a part of a guide body that is angled relative to a part of the flushing head that has the nozzles or that is offset with respect to its longitudinal axis for better alignment of the flushing head to be pushed through a channel. is. The nozzle part, which then also has the receptacle for the flushing hose, is slightly angled with respect to its longitudinal axis relative to the channel wall, which also leads to a stable guidance of the flushing head through a channel in combination with a then obliquely away from the flushing head hose. The same applies to staggered longitudinal axes of the nozzle part and the guide body. The longitudinal axis of the hose and the nozzle part may also correspond approximately. In addition, it is advantageous if the flushing head comprises a functional part, which has, for example, a receiving space. As a result, the functional part, in particular the functional part formed integrally with the guide body, can be made lighter than the nozzle part, which again benefits a guidance of the flushing head. The functional part may also be integrally or in particular interchangeably connected to the nozzle part and connect directly or indirectly thereto.

Particularly advantageously, the flushing head is provided with an opening in the main movement direction receiving space within the functional part, in which a camera is arranged. As a result, the flushing head and in particular in the operating position with a flushing hose arranged thereon are able to completely replace the camera or support carriage known in the prior art. The rinsing head and rinsing hose can be routed without carrier device in main channels as well as in house connection channels and due to the integrated camera, camera carts are no longer necessary. This leads to much more favorable channel inspection expectations, whereby the camera can be operated with the rinse car, for example, via a data recording and playback device, such as a small portable computer. The camera may preferably also be a pivotable camera which is arranged on the outside at least partially in the receiving space or on the rinsing head and leads to a better image of the channel. Such a camera can also be used to inspect subfloors directly below the flushing head. Especially in combination with a guide surface, which can also be used with guide flanges such as webs or other guide belts. te can be supplemented or replaced, and the associated targeted alignment of the rinsing head, the camera is specifically aligned.

By a relation to a guide surface or a guide element in

Longitudinally angled lower side, the flushing body can be particularly well inserted into house connection channels. If a house connection channel is to be examined, the flushing head is pushed / pulled in its direction and possibly rotated about its longitudinal axis. Due to the lack of resistance on the guide surface, the flushing head rotates in the e.g. left or right branching channel inside, which is supported by the bevelled lower side and the associated pointed execution of the flushing head.

Preferably, the front-facing lens of the camera is surrounded by an LED light ring, which illuminates the space to be considered well.

The device is further improved if the flushing head is provided with a locating device, via which a clear localization in addition to any bebe measures such as meter wheels is possible.

In a further embodiment according to the invention, the flushing head is assigned a joint, by means of 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. Advantageously, by the joint of the Spülkopfzu- formed with gear, so that the joint is part of the flushing head and having a preferably flange-shaped region to which the flushing hose can be attached.

The use of 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. Although the weight forces acting on the flushing head of the hose and of the water carried therein can not be completely ruled out, the joint minimizes the influence of the force exerted by the hose and the water flowing in it on 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.

Advantageously, the joint is provided with a hollow ball head part, which is arranged in a part of the flushing head and in particular is movably mounted in corresponding joint cup areas of the flushing head. The water can then be transported through the hollow ball head part in the direction of the nozzles and the hose can be flange-mounted centrally on the hollow flange part. While on the one hand a control of the flushing head via the nozzles is still possible, wherein the nozzles can be operated for example via solenoid valves or switchable by different water pressure, the joint advantageously has a degree of freedom and thus a pivot axis through which the flushing head relative to the hose An anglebar is. In particular, this pivot axis is transverse to the direction of the force provided for lifting the nozzle.

For improved orientation in the channel, the flushing head may be provided with a light aiming device, which is preferably equipped with a laser or other blasting medium for illuminating a small punctiform area. By knowing the angle at which the jet is emitted by the flushing head and the distance to the flushing head resulting from contact with the channel, the distance of objects targeted by the beam in the channel can be accurately determined. Thus, for example, defects, house connections and other objects can be located, wherein in addition to the removal of the luminous point from the flushing head, the unwound length of the hose is taken into account and can be automatically detected for example via a data acquisition and evaluation.

A flushing head according to the invention can be provided with a position sensor, via which an orientation of the flushing head is defined in one or more dimensions can be. This also improves the positioning of objects in the channel.

In a working position in which the flushing head is located at the upper vertex of a channel, the pivot axis extends in a rectilinear Kanai preferably at least approximately in a plane which is parallel to the longitudinal direction of the channel and in which the pivot axis is employed at right angles. Considered in a longitudinal direction of the flushing head thus the flushing head can exert a nodding movement. The definition of a pivot axis thus serves to transmit a torque from the hose via the joint to the flushing head and to align the flushing head. By defining such a pivot axis thus exerted by a hose rotational movement leads to the pivoting of the head about its longitudinal axis. The combination of a rotary motion associated with an additional kinking of the flushing head this can be ushered into branches of the channel in a much simpler way and can easily reflect kinks and changes in direction of the channel with.

A slight mobility due to manufacturing tolerances or the like. not excluding a further axis, it is particularly advantageous if the flushing head has only this one pivot axis. The part of the flushing head which does not have the part of the flushing head facing the flushing spray can thus be transferred, for example, by a rotation of the hose through 90 ° in a clockwise direction into a position lying against a right side wall of the channel. By means of the water discharged from the asymmetrical nozzles or through the water discharged through the nozzles. practiced force, the flushing head is then pressed in the presence of a branch arranged on this right side in this, wherein the joint kinks. The introduction of the flushing head into such a branch can be improved by a flattening of the flushing head on a bottom surface opposite the guide surface. The flushing head is thus preferably flattened on its underside and formed angled to its longitudinal extent.

The particular one degree of freedom having joint is provided with a flange which advantageously has a profiling for connection to the flushing hose.

A flushing device according to the invention, for example a flushing trolley for channel cleaning, is able, in particular in a training with a camera, to replace the camera carriage previously known from the prior art. Even without an integrated camera can be dispensed with a guidance of the hose through the camera dolly. The flushing hose can be easily pushed past the rake car operator behind a camera dolly or pushed or pulled from another side of the duct to the camera dolly. The often erroneous pivoting of the flushing hose by the vulnerable mechanics of the carrier vehicle is eliminated.

Preferably, the flushing device comprises a flushing hose rotating device, by means of which the flushing hose is rotatable about its longitudinal axis. While experienced personnel can also turn the flushing hose directly manually, this can Rotation, which may require a greater force application with correspondingly far-developed irrigation tubes, be supported by, for example, to be arranged on the purge hose lever. This may also be a device provided with motor or hydraulic actuating means.

Advantageously, the flushing device of a further embodiment of the invention is provided with a telescopic arm, which allows the easier handling of the flushing arm and in particular in a direction vertical to the horizontally extending ground or ground is movable.

For the rotation of the flushing hose, the flushing hose rotation device preferably has a holding unit with a recess provided for receiving the hose, in which the flushing hose can be held against rotation. The holding unit can advantageously be arranged at one end of the telescopic arm and be rotatable about a longitudinal direction of the flushing hose or about an axis which runs parallel to the longitudinal extent of the telescopic arm. For this purpose, the rinsing tube rotating device preferably has at least one pressing means which can be transferred from a non-operating position into a pressing position, by means of which a force can be exerted transversely and / or longitudinally of the tube by the rotating device. By turning the holding unit, a part of the holding unit or a part of the telescopic arm then a torque can be transmitted to the hose, which extends through the hose to the. Flushing continues and at least partially contributes to the rotation of the flushing head. The flushing hose rotating device is in particular motor, pneumatic and / or electrically operable, so that for a rotation of the hose from the operating personnel of the hose does not have to be moved by hand. Preferably, the rotation is electrically actuated. The pressure means is in particular pneumatically actuated, since then a maximum pressure on the hose is adjustable via simple pressure limiter. Rather, the operator may focus on the rinse head and its data displayed by a pickup device. The control of the flushing hose can in this case be effected in particular via a joystick control or a rotary wheel control, which permit an intuitive guidance of the flushing head.

As a pressure means or in particular rotating or rotatable pressure means in the form of wheels, belts, chains or the like. Rolled on the hose means are used.

Advantageously, the or the pressure means have a profiling which acts in the pressure position transversely to the longitudinal direction of the flushing hose, so that a rotation of the flushing hose can be improved without slippage of the hose. For example, these are rollers, belts or the like. Circumferential, profiled means, along which the hose runs along and roll in the longitudinal direction on the hose and having a circumferentially extending longitudinal profiling in the form of circumferential grooves. An improved control of the flushing head and this rotating hose is then when the pressure means is designed as a rotating and / or rotatable attachment means, so that a pivoting of the hose and thus the flushing head and a propulsion thereof can be carried out independently and simultaneously. For this purpose, the investment means may also be designed to drive the rinsing head.

The control of the flushing hose rotating device, which in particular can be actuated pneumatically, is matched with the data acquisition to the effect that the operation of the device and the resulting movement of the flushing head are detected directly and preferably position data on location and orientation of the flushing head can be displayed directly.

The main extension direction of the telescopic arm and the pressure direction of the Andruckmitteis are aligned transversely to each other to allow optimal control of the flushing head.

By forming a holding unit at the lower end of the telescopic arm, this can also serve to cover a channel opening at the same time, so that the protection of the operating personnel also secured by the Spülschlauchdrehvorrichtung.

In order to reduce the susceptibility of the supply line leading to the flushing head, the flushing hose can advantageously at least partially with the Camera cables are connected, for example via a shrink tube. The supply line can also be integrated into the flushing hose itself, for example, in the armor or its water-bearing cavity, which then leads to a better handling thereof by only one cable.

Equal or similar parts are - if appropriate - provided with identical reference numbers. Individual technical features of the exemplary embodiments described below can also lead to developments of the invention with the features of the above-described embodiments.

An inventive flushing according to Figure 1 has a nozzle part 2, to which a functional part 4 is flanged sealingly. To form a guide surface, an upper edge 6 in the longitudinal direction of the flushing head is longer than a lower edge 7. This results in a bevelled end flare to the nozzle part 2, whereby the area around the edge 6 is suitable as a guide surface. A receiving space 8 (see Fig. 2) is sealed with a cover 9. About the cover 9, a camera included with an LED light ring is set in the receiving space 8. The cover 9 has a transparent and to be screened by the LED, annular disc 1 1, which defines a circular disk 19 in this case and a lens 12 of the camera. When using a movable adjusting ring 13, the lens of the camera can be focused.

At the end of the flushing head opposite the front end of the flushing head, the nozzle part 2 has a plurality of nozzles 14 which are arranged in the circumferential direction about a longitudinal axis of the nozzle part 2 and about a longitudinal axis of the guide body or functional part 4.

The nozzle part 2 further has a rinsing head access 16, which serves to define a rinsing hose. From the Spülkopfzugang 16 from the nozzles with the medium, preferably water, supplied.

During operation of the flushing head, it is designed with a flushing hose arranged thereon by virtue of the nozzles in such a way that it rests with the surface around the edge 6 without twisting of the flushing head in the orientation shown on an upper wall or a vertex of a channel to be inspected or cleaned , The camera 17 looks in this case in the direction of a longitudinal direction of the channel. The angled arrangement of nozzle part 2 and guide body 4 leads to a stable position, although the weight of the hose additionally pulls down the flushing head, which is however due to the oblique arrangement of the nozzle partly already partially compensated. If the functional space 8 with the camera 17 is not flanged at an angle to the nozzle part or is not formed obliquely, the camera 17 could alternatively be arranged obliquely in the receiving space to look in the longitudinal direction of the channel.

Alternatively or additionally, the cover 11 shown of the LED unit 18 and the glass attachment 19 of the camera could be designed so that they provide a fish-eye view of the environment and thus provide the greatest possible coverage of the space to be considered. A positioning pin 21 serves for the exact arrangement of the camera unit in the functional space. About a seal 25 pinching brass ring 22, a seal of the intended for receiving the camera cable channel 23 is achieved. This is then sealed with the camera cable opposite the channel to be cleaned.

Nozzle part 2 and guide body 4 are fastened to each other via screw means 24, which causes easy maintenance, in particular of the nozzle part 2. In the rear view of the nozzle part according to the arrow A in FIG. 2, the arrangement of the nozzles about a longitudinal axis 26 of the nozzle part 2 can be seen in FIG. Lower nozzles 27 are formed larger than the nozzles 14 and serve in particular as floating nozzles. The right-side nozzles 14, which are also present in the figure on the outer circumference, serve primarily with the two nozzles 14 visible in FIG. 1 as cleaning nozzles. In addition, these nozzles and the other also used as a propulsion nozzles nozzles 28 has a stabilizing function of in the channel during operation floating flushing head. It is understood that the nozzles 27 and 28 also have cleaning or counter to the force of gravity effects.

The jet direction of the inner nozzles 28 and of the outer nozzles 14 and 27 are angled relative to one another and at different angles with respect to the longitudinal axis 26 (FIG. 4).

In order to ensure optimal guidance during operation, the guide body is also angled with its longitudinal axis 29 by about 13 ° relative to the axis 26. Especially at values between 8 ° and 20 °, a good guidance of the rinsing heads in the channel has resulted. In this case, the cone-shaped head of the guide body ensures good sliding over it even in the case of heavy soiling and obstacles at the channel interior.

The lateral surface of the cone 5 is inclined relative to the lateral surface 31 of the guide body to advantageously 20 ° to 45 ° in order to slide along obstacles well. Due to the structure of the flushing head results in a preferred direction of movement of the flushing head forward / upward, but which leads to a rotation of the flushing head to a pivoting of the flushing head to one side of the channel. In addition, this orientation of the flushing head is particularly well suited to meet at a shallow angle to a main channel abutting house water connections and to introduce the flushing head can in this. For this purpose, rinsing heads provided in particular with controllable nozzles can be arranged along a longitudinal axis. For example, be rotated by 90 ° or 180 ° and be provided with an opposite thrust to push well into the small house connection channels can.

In the exploded view of FIG. 4, the camera is shown as a simple fixture, which is completely inserted into the receiving space 8. The cover 9 is also a single mounting part, in which the individual lenses or to be screened cover are used. The whole device can thus be both easy to build and disassemble for maintenance purposes.

For this purpose, the nozzles are formed as by means of Allen key in the nozzle part 2 can be screwed, preferably made of ceramic nozzles.

Although the flushing head with guide body 4 and nozzle part 2 is formed in two parts, it can of course be formed in one piece or in several parts. The longer the edge 6 is formed compared to edge 7 and the more strongly the cylindrical part is bent, the more intersect the longitudinal axes 26 and 29. This can be made dependent, for example, on the weight of the flushing hose to be lifted during operation. The heavier the rinsing hose is, the stronger is the angling, whereby, for example, the camera cable with the rinsing hose is protected together by means of a shrinking tube.

According to the invention, a functional part 4 can be replaced as needed. Thus, the embodiment according to the invention according to FIG. 5 has a functional part 4, which has a non-cylindrical base body. Rather, the functional part 4 is designed so that it has a clearly pronounced guide surface 32 which serves to guide or align the flushing head. The functional part 4 is further offset with respect to a vertical axis at the nozzle part 2 attached, which can be seen in particular in FIG. 6 and leads to an offset of the two longitudinal axes of the nozzle part and functional part 4. A longitudinal axis 33 of the functional part is offset relative to a longitudinal axis 26 upwards. Through the guide or alignment surface 32, the flushing head is aligned in operation so that the camera looks in the longitudinal direction of the channel. The flushing head according to FIG. 6 has an LED ring around the lens which has been changed compared with the previous exemplary embodiment. Instead of a positioning pin 21, moreover, the receiving space is provided with a peripheral edge 34, which lead to a precise arrangement of the camera 17 in the receiving space 8. Instead of the guide surface 32 or in addition to it, guide elements in the form of, for example, longitudinally arranged webs may be provided on the flushing head, which serve for the targeted alignment of the flushing head or support its movement through the channel.

The flushing head according to the embodiment of FIG. 7 is like the flushing head of FIG. 1 constructed in several parts and has a nozzle part 2, in which according to the invention a universal joint is integrated as a joint 40. A flange portion 41 of the hinge 40 protrudes from the flushing head and serves to attach a clamp 42 of the flushing hose end. Part 42 represents a shortened Aufpresskupplung, the at the

Flange 41 of the joint head is flanged and preferably a maximum Extension of 6 cm considered in the direction of the flushing hose has. By using such a shortened press-on coupling, the flushing head can be improved into a branch, which is arranged, for example, at a 90 ° angle to the channel. On the upper side of the flushing head there is again a guide surface 32, wherein flushing heads according to the invention are already adequately guided if they have two points which are spaced behind one another in the longitudinal direction and serve the abutment at a vertex of the channel. This may be two humps or projections lying one behind the other in the longitudinal direction, ie in the direction of a dashed line, which is congruent to the section line 43 in FIG. 8.

By means of a guide line or guide surface defined by two or three points, a well-conducted and movable flushing head is created, in particular in connection with a joint with a degree of freedom or a pivot axis.

The flushing head according to the invention according to FIG. 7 also has a camera insert, which is tightly closed by a cover 9. This cover 9 holds a disc 11, behind which for illuminating the channel advantageously a plurality of LEDs is arranged as well as in the recess of the disc 11 located lens 12 of the camera.

The joint of the embodiment according to the invention of FIG. 8 has one degree of freedom and is located about a plane lying in the plane of the figure and transverse to the cutting line 43. pivoting pivot axis. With reference to FIG. 8, the head thus pivots vertically upwards or dives into the figure.

The ball head 44 is held in a socket which is formed by two parts 46 and 47. In the part 47, this is a Verschraubungs- part, which is the simple determination of the ball head and which has on its outside a not-shown thread 48, about that the ball head part can be screwed into the housing of the flushing head. Through the hollow inner part 49 of the ball head, the incoming water passes to the nozzles 14 and 28. Instead of a guide of the data lines through the area 23, these may also be passed centrally through the hollow ball and head centrally into the flushing head.

Advantageously, as can be seen in FIG. 9, the flushing head is formed asymmetrically about a longitudinal axis 26. The main part of the flushing head is offset in the direction of the top, for example, the guide surface 32. The underside is angled with respect to the longitudinal axis 26 with an edge 51, while an upper side with a visible in the view edge 52 is approximately parallel to the axis 26. As a result of such an asymmetric design, the flushing head can swivel very well into even small branches of, for example, 10 cm in diameter.

The pivotability of the flushing head is defined in FIG. 9 by an angle α. Advantageously, rinsing heads according to the invention are at an angle of + α or - α with α greater than or equal to 10 ° swiveled. Preferably, the flushing head is pivotable overall over a range of 30 ° to 70 °, more preferably in a range of 40 ° to 60 °. The angle α in this case is measured in accordance with FIG. 9 as the angle about which the flushing head pivots, for example, about a pivot axis defined by a bolt of the ball joint, which is held in the ball socket. + ct hereby means a pivoting upward, -a downward and thus in the figure in a region below the longitudinal axis. Up and down can therefore also mean a position relative to the orientation of the flushing head.

10 shows a plurality of LEDs 53 on a metal carrier 54, which serves to cool the LED and acts as an LED light ring. This metal ring is suspended on the preferably made of metal housing and the flushing head and thus very well cooled, which causes an extension of the life of the LED's.

Due to the preferably symmetrical arrangement of the LEDs around a lens 12, the channel is uniformly illuminated. Preferably, a lower LED 53 is provided with a greater luminous intensity than an upper LED 53, in order to illuminate well located at the front and under the flushing head at a located at the top of the channel arrangement of the flushing head.

Not shown in FIG. 10 is a light targeting device, which can be arranged in particular in the same room in which the LEDs 53 are arranged. Alternatively or additionally, the device can also be arranged in a bore, for example, of the cone-shaped body 5. In the functional part of the flushing head Preferably, the position sensor is also arranged, via which in particular an inclination along a channel longitudinal axis or a rotation about a longitudinal axis of the flushing head can be detected and evaluated.

According to FIG. 11, a flushing device according to the invention is provided with a flushing head rotating device 61 which has at its lower end a holding unit 63 held by a telescopic arm 62. This holding unit has three pressure means 64 which, in the present case, are designed as revolving rollers and can exert a system pressure on a rinsing hose to be led through a recess 66. The pressure means 64 are rotatable relative to the lid 68 together with a lower part 67 of the holding unit. At the same time, the holding unit 63 is designed to cover the opening of a channel, whereby it does not have to be additionally covered during operation. Through the central opening of the hose can still be well inserted into the channel, the rinsing head under high pressure water is effectively prevented by leaving the channel by the holding unit and / or an additional attached to this or on the telescopic arm cover. An injury risk for the operating personnel is reduced.

Of the three pressure means only the one right pressure means via a lifting cylinder 69 in an inoperative position can be transferred. In the investment position, however, the applied pressure is distributed over all three pressure means. The rollers run off the hose and serve to transmit torque to the hose. In the bottom view according to FIG. 12 it can be seen that the pressure means 64 are distributed approximately symmetrically about the hose. About a lever mimic with a rod 71, the right pressing means located in the figure is moved by means of the two lifting cylinder 69 in the direction B.
