    The invention relates to a tool for cleaning large areas, in particular ship hulls, with a tool body and at least one nozzle body whose nozzles are positioned radially starting from the surface center of the nozzle body.
    A tool of the type mentioned can be found in WO 1996/12570 A2, wherein a substantially cylindrical tool body is provided on the circular base of a nozzle body is arranged with a plurality of nozzles. This rotating nozzle body in operation has a substantially rectangular base. A disadvantage of this device is that the removal rates are very low, for example, when removing paint layers of a ship's hull due to the relatively small effective area of the tool.
    It is therefore an object of the invention to provide a tool of the type mentioned, which has a high efficiency and whose operation is environmentally friendly.
    This object is achieved in that two rotating nozzle body are arranged on the tool body, and further at least one sealing element is resiliently mounted on the tool body. The arrangement of two rotating nozzle body on the base of the tool body, a high removal rate is achieved. Since the tool is preferably used on non-planar surfaces such as Schifumpf, and incurred in the removal of impurities and paint layers by water jet and / or sand blasting large amounts of Abtragsmaterial that should not get into the environment, the invention provides that the tool body is arranged at least one resilient sealing element. Due to the resilient mounting, the sealing element adapts to the contour of the surface to be machined and the tightness of the tool is thereby substantially improved.
    In a preferred embodiment of the invention, the sealing element is designed as a substantially annular brush body. This brush body encloses the two rotating nozzle body and seals the tool body to 0 * 1 2 of the surface to be machined against the environment, so that the abrasive material can be sucked through the tool body.
    The tightness of the sealing element is further significantly improved in a particularly preferred embodiment of the invention, if the sealing element additionally has a substantially flat plastic seal, in particular neoprene, which at least partially surrounds the brush body. By combining a flexible, flat plastic seal with a brush body, the tightness increases significantly, which also reduces the required performance of the exhaust system.
    Particularly preferably, it is provided that the nozzle body has three rotor arms, in which the nozzles are positioned. By this rotor system, a high Abtragsieistung can be realized, because this nozzle body is particularly suitable for high rotational speeds. At the same time a suction effect is generated by this shape of the nozzle body, which additionally supports the suction of the material removed.
    In this case, it is particularly preferably provided that nozzles are arranged along the longitudinal axis of the rotor arm of the nozzle body, wherein the longitudinal axes of the nozzles intersect the base surface of the rotor arm substantially orthogonal. Investigations by the applicant have shown that this arrangement allows optimal removal of impurities or paint layers of the surface to be treated.
    If the surface to be worked on is not to be completely cleaned, but only in certain areas, as is usually the case with ship hull maintenance, then it is necessary for the cleaning or coating of the surface following the cleaning to make the transition between the cleaned area and intact area not jumped, but running. Therefore, in a particularly preferred embodiment of the invention, at least one nozzle arranged at the distal end of the rotor arm is provided on at least one rotor arm, which intersects the base of the rotor arm at an angle of between 2 ° and 10 °, preferably 5 ° the orthogonal deviates to the base of the rotor arm. Below " distal end of rotor arm " is understood in this context 3 that end of the rotor arm, which faces away from the surface center of the nozzle body. This inclination of the last nozzle reduces the rate of material removal in this area, resulting in the desired " gentle " Transition between machined and unprocessed surface is achieved.
    An essential point in the use of the tool according to the invention is the avoidance of the escape of erosion material into the environment. For this purpose, an exhaust system is provided, wherein the tool body has at least one, preferably two or four suction openings for the connection of an exhaust system. In this case, it is particularly preferably provided that the shape of the tool body essentially corresponds to an open cylinder with an elliptical base surface, two suction openings preferably being arranged on the longitudinal sides of the base area and two suction openings on the tool body wall in the region of the vertices of the elliptical base area. Of course, all suction openings in the tool body wall and / or the base can be arranged.
    The suction performance is further improved if, according to a further embodiment of the invention, at least one suction channel is provided in the tool body wall, which opens into at least one suction opening. Thus, the flow conditions are improved within the tool body, so that the suction also increased significantly in combination with the sealing element.
    In a particularly preferred embodiment of the invention, the nozzle bodies are drivable via a drive system with a hydraulic motor and a gearbox.
    The invention is explained in more detail below with reference to a non-limiting exemplary embodiment with associated figures. Show in it
    Fig. 1 is a first perspective view of the tool from the front, and
    Fig. 2 is a sectional view of the tool body.
    The tool 100 according to the invention according to FIGS. 1 and 2 has a tool body 110 which has a substantially elliptical base 111, on which two nozzle bodies 200 are arranged. Further, 0 < r - Ος-ΙοΊΖ 4 encloses the two nozzle bodies 200 a tool body wall 112 substantially orthogonal to the base 111.
    On the outside of the tool body wall 112, a sealing element 120 is arranged, which consists of a brush body 121 and a neoprene gasket 122 which partially surrounds the brush body 121. The sealing element 120 is fastened to the tool body 110 via four spring bearings 123, wherein this resilient mounting permits adaptation of the sealing element 120 to the surface to be machined. In operation, the tool according to the invention 100 due to this combination seal consisting of brush body 121 and neoprene seal 122 and the resilient mounting on the spring bearings 123 optimal tightness against the environment, so virtually no Abtragsmaterial enters the environment and at the same time the suction can be optimally dimensioned. For the suction of the space material suction openings 113 are provided in the tool body 110, wherein the flow conditions within the tool body by the arrangement of suction channels 114 which lead to the suction openings 113, further improved.
    In order to obtain an optimum removal rate of the tool 110 according to the invention, the nozzle bodies 200 each have three rotor arms 201, on which nozzles 202 are arranged substantially radially.
    On at least one rotor arm, as shown in Figure 2, the longitudinal axes A of the nozzles 202 arranged substantially normal to the base E of the rotor arm 201, only the nozzle 202 'at the proximal end 203 is made inclined, the angle α in the present Embodiment of the invention is about 5 °. In this way, a lower removal rate is obtained in the area of the surface machined by this part of the rotor arm 201, as a result of which the desired profile between machined and unprocessed surface is obtained. Via a central supply line 115, the cleaning agent, for example water, abrasive agents such as sand or mixtures of abrasive agents with water or solvents by means of high pressure (500 to 3,000 bar) to the nozzles 202, 202 'passed, and via the nozzles 202, 202' brought to the surface to be machined 5. A hydraulic motor in this case causes, for example via a bevel gear, a rotation of the nozzle body 200 in order to obtain a uniform machining of the surface. The resulting waste of removed material, as well as the water used and / or abrasive agent are sucked through the suction holes 113 to minimize stress on the environment with these materials. Furthermore, the sealing element 120 according to the invention supports the suction during the removal.
    Finally, sensors may be additionally attached to the tool body 110 to monitor and control the optimal alignment of the tool 100 with a surface. These may be, for example, proximity sensors based on ultrasound technology and the like. Likewise, inspection devices such as cameras and the like may be provided. The tool 100 has proven particularly suitable for use in automated maintenance systems for processing curved surfaces, such as ship hulls. Here, the tool 100 is arranged in a tool holder, which is brought via an arm system to the surface to be machined.
