Definitions

  • the invention relates to a helicopter-based cleaning device consisting of a helicopter on which or in which a tank with a cleaning liquid and a holding frame are attached to which on one longitudinal side an elongated washing lance is attached, through which the cleaning liquid to the tip of the wash lance can be brought and to which a pump with a drive for conveying the cleaning agent is mounted.

  • Such a method of purification is e.g. known for the rotor blades of large wind turbines. If the facilities are so large that the rotor blades from the ground no longer with reasonable effort, e.g. are accessible by mobile lifts, the rotor blades are spent in a vertically downward position and blocked.

  • the helicopter equipped in this way is controlled by its pilot, for example, along the insulators of high-voltage lines, so that cleaning fluid emerging from the tip of the washing lance accompanies itself high pressure impinges on the insulators and solves by the force of the impact thereon impurities and flushes away.
  • One cause for an abrupt interruption of the flow of the cleaning agent may be a gust of wind which hits the helicopter shortly before the tank is completely emptied with the cleaning fluid. To compensate for this blast, a change in the position of the helicopter is required, which also changes the liquid level in the almost empty tank for the cleaning liquid.
  • the object of the invention is to design, arrange and equip the components required for a cleaning device on a helicopter in such a way that its operation is also in critical flight conditions - such as, for example, in gusts - as few repercussions on the aircraft as possible.
  • the invention teaches that the underside of the tank in the normal position of the helicopter is at least partially inclined relative to the horizontal, so that the rest of the cleaning liquid collects for the most part on a relatively small area and in the immediate vicinity of this surface of the intake manifold of a Pipe or a hose is arranged, which (r) is connected to the pump. This ensures that always - regardless of the exact orientation of the helicopter relative to the horizontal - suck the suction nozzle of the pump cleaning liquid and can promote to the nozzle at the top of the wash lance.
  • the invention proposes that the underside of the tank is shaped like a segment of a hollow truncated cone or a hollow pyramid.
  • the pump can still suck in cleaning fluid and continue to escape without hindrance even in the case of a greatly inclined attitude of the helicopter. This not only shortens the processing time, but also noticeably increases the security against unexpected air blasts.
  • a further embodiment with an increase in the security against instabilities in the helicopter's attitude by the absence of the flow of cleaning fluid is the installation of at least one so-called "buffing plate" in the tank. orderly.

  • the nozzle is to be arranged pivotably and move either along a straight line oscillating or on a circle. As a result, the jet moves out of the nozzle on a fan-shaped or hollow conical surface.

  • at least one brush or a rotating brush and / or a wash cloth or at least one rotating wash cloth be attached to the tip of the washing lance as an additional cleaning mechanism.
  • Such a cleaning mechanism enhances the cleaning effect sustainable and thus allows a faster flying over of the surface to be cleaned, which is equivalent in the end to a reduction in aviation effort.
  • an extension tube is pivotally mounted, at the free end of the washing nozzle or the cleaning mechanism are arranged.
  • This extension tube is replaced by an auxiliary actuator, e.g. a spring or a pneumatic cylinder spread. This further reduces the accuracy with which the pilot must follow the contour of the surface to be cleaned. As long as it reaches a surface which is arranged within the pivoting range of the extension tube, sufficient cleaning of the surface is ensured.

  • a position control loop is established which adjusts a constant distance between the washing nozzle and / or a cleaning mechanism and the surface to be cleaned.
  • the pilot's positioning work may be transferred in part to a second operator by attaching two handles to the wash lance that are located within reach of an operator sitting in the interior of the helicopter. Using these handles, the second man in a helicopter can maneuver the wash lance and thus relieve the pilot of much of his task.
  • this second operator can only move the washing lance manually.
  • the invention proposes that the wash lance is movable by two main actuators whose direction of action is offset by about 90 degrees from each other.
  • the washing lance can be moved not only in one direction, but in two directions, thus describing a spherical segment with its tip.
  • These two main actuators can be activated by the operator, for example, with one control button each. If the main actuators do not have such high self-locking that they block the movement of the wash lance in their passive state, it makes sense to move the control keys close to or on the handles with which the operator controls the wash lance.
  • the holding work is supported by the operator and the actuators amplify the movements intended by the operator. Since such an operation requires getting used to, in addition to the intention of the operator to operate the wash lance in a particular direction, the timely actuation of the control button, it makes sense for a simplified operation to control the actuators as a servo device, ie to incorporate a detection for the force exerted by the operator on the handles on the wash lance and activate the actuators by these sensors. For this purpose, a proportional detection of the force exerted by the operator will usually be required, which in turn with a proportional control of

  • Another advantageous equipment variant increases the safety of the operation for the drive of the pump: If an internal combustion engine is used for it, it must suck in its combustion air. At higher speeds of the aircraft, the flow rate is so high that the negative pressure generated by the engine is no longer sufficient for safe air intake and the engine stops. Then the pilot does not have to land and put back on the ground the combustion engine mounted outside the boom.

Abstract

La présente invention concerne un appareil de nettoyage à base d'un hélicoptère, lequel appareil est composé d'un hélicoptère auquel ou dans lequel sont fixés un réservoir de liquide de nettoyage et un cadre support. Une lance de lavage allongée est fixée au cadre support, sur un côté longitudinal. Le liquide de nettoyage peut être amené à travers cette lance de lavage jusqu'à la pointe de cette dernière. Une pompe montée sur le cadre support comprend un mécanisme d'entraînement permettant de transporter le produit de nettoyage. Lorsque l'hélicoptère se trouve en position normale par rapport à l'horizontale, le dessous du réservoir est au moins partiellement incliné de manière que le reste du liquide de nettoyage s'accumule en grande partie sur une surface relativement très petite et l'orifice d'aspiration d'un tube ou d'un tuyau relié à la pompe se trouve à proximité immédiate de cette surface.
