  • the present invention relates to a drive system for a water lance blower according to the preamble of claim 1 and a method for its operation.
  • the cleaning of heating systems is also carried out, among other things, with the help of water lance blowers, which emit a concentrated water jet through the combustion chamber onto the opposite wall.
  • water lance blowers which emit a concentrated water jet through the combustion chamber onto the opposite wall.
  • the water jet from water lance blowers generally follows a certain predetermined path on the surface to be cleaned, also called a blow figure, this path generally running in a meandering or spiral manner and possibly avoiding obstacles, openings or other sensitive zones.
  • Another two-axis control is also known from WO 93/12398, which precisely controls the water lance by means of two spindle drives running perpendicular to one another, which in turn are held by means of a guide frame.
  • the blowing lance is guided by mechanisms and central drives, drive and bearing elements being mounted and arranged in a frame construction in the space around the blowing guides, which take up a large space.
  • the often large length of the lance and the water supply lead to great leverage and Forces, which in turn require corresponding guides, drives and frames.
  • each hatch there is not enough space available in the area of each hatch, which can be any opening in which a water lance blower should advantageously be arranged.
  • the object of the present invention is therefore to create a drive system for a water lance blower, which can be arranged flexibly even in confined spaces and also allows the free choice of any blow figures and any movement speeds.
  • the object of the invention is also to provide a suitable method for operating such water lance blowers.
  • the water lance blower according to the invention for cleaning heating systems can be moved by at least one movement element which is connected at one end to the water lance blower and at the other end directly to the heating system.
  • the drive system is equipped with position transducers for the precise determination of the position of the water lance, as a result of which a controlled driving style can be achieved.
  • the movement element is at least part of a manipulator arm.
  • One end of the manipulator arm can preferably be attached to the heating system in such a way that the water lance blower is easily accessible in terms of maintenance and inspection, without unnecessarily restricting the space on a work platform.
  • the manipulator arm itself can be designed freely, and in one embodiment the movement element itself is the manipulator arm.
  • the arrangement of the ends of one or more movement elements in one plane, which extends perpendicular to a vertical plane through the movement point of the water lance, allows this movement point to be moved far forward into the hatch or the heating system, as a result of which larger swivel ranges and more favorable leverage ratios result in the drive system.
  • the vertical level is to be understood as a corresponding horizontal through the movement point. If only one movement element is used, this is preferred, its length and its direction can be changed, and thus fulfills the functions of a manipulator arm. If there are two movement elements, they only need to have linear drives to move the water lance on any path.
  • a third movement element which can then support the drive, is very important for such arrangements.
  • more than three movement elements can also be used.
  • very complex, non-linear movements of the movement element or elements are required, for example, to carry out a meandering blow figure, so that simple control, in particular timing control, is no longer an option for such arrangements.
  • the drive system has displacement sensors for the exact determination of the position of the water lance, so that now it is not possible to use a pure control but a controlled control along a target movement line.
  • the position transducers enable precise control of the blow figure so that the movement elements can be regulated accordingly.
  • the drive system also allows certain parts of the blow figure to run at a first speed and other parts of the blow figure, for example non-contaminated or sensitive areas, to run at a second speed.
  • any blow figures and any speed profiles can be programmed or saved by recording on site.
  • the displacement transducers can either be arranged in the movement elements themselves as typical displacement or angle transducers, or they can be arranged on one or more displacement transducer arms. It is important that they can measure the exact position of the water lance in relation to a reference position, which may be determined before the blowing process begins. Capacitive, inductive or magnetic sensors as well as digital pedometers and the like are suitable as displacement sensors.
  • the control takes place in a common control electronics which receives the measured values of the displacement transducers, compares them with the target values of the given blow figure and controls the movement elements accordingly.
  • the movement elements can be, for example, hydraulic or pneumatic reciprocating pistons, as well as known spindle or rack and pinion drives, also electric or magnetic drives or the use of a manipulator arm are possible.
  • it can also be advantageous to adapt the movement elements to the spatial conditions with levers, cables, chains, swivel joints and the like.
  • One method for operating the system according to the invention is that the system is set up on site and then the blowing figure is run for the first time using a template or by visual observation of the water jet and the associated measured values of the displacement sensors are stored. It is also possible to calculate the setpoints for the displacement transducers for any blowing figure after the measured values of the displacement transducers have been determined for specific reference points.

Abstract

L'invention concerne une soufflante pour lance à eau utilisée pour nettoyer des installations thermiques. Une lance à eau (6) est montée mobile (5) avec son embouchure sur ou dans une lucarne (2) et peut projeter un jet d'eau jusqu'aux zones d'une paroi pouvant être atteintes depuis la lucarne (2) à travers l'installation thermique en fonctionnement où se trouvent des flammes et/ou des fumées. La soufflante pour lance à eau peut être déplacée par au moins un élément de déplacement (8.1, 8.2, 8.3) relié à une extrémité à la soufflante pour lance à eau et à l'autre extrémité directement à l'installation thermique. Des capteurs de déplacement servent à déterminer avec précision la position de la lance à eau (6). On utilise de préférence trois éléments de déplacement (8.1, 8.2, 8.3) dont les points de fixation (9.1, 9.2, 9.3) forment avec le point de déplacement (5) de la lance à eau (6) des angles compris notamment entre 80° et 140° environ. Ces soufflantes pour lance à eau peuvent être utilisées même dans des conditions défavorables, en ce qui concerne l'espace disponible, et projeter tous motifs voulus d'eau pouvant être prédéterminés à volonté et avec différents profils de vitesse.
