- the cleaning system consists of a, the diameter of the well or container adapted, e.g.
- the cleaning head 1 is advantageously adapted to the shape of the well or the container or pipe system to be cleaned and therefore may have rectangular or polyhedral cross-sections.
- the cleaning head 1 consists of a part.
- the high-pressure water supply 7 via a high-pressure line 7 from above centrally into the cleaning head 1. About radially arranged channels, the high-pressure water supply 7 is arranged to those on the outer circumference
- Cavitation and high-pressure nozzles 2 which are advantageously arranged alternately in two planes.
- a dirty water pump 3 the suction is located centrally within a shielding hood 4.
- the dirty water pump 3 is mechanically connected via a flange 10 with the shielding hood 4 and the cleaning head 1.
- the shielding hood 4 and the cleaning head 1 can be easily separated from the dirty water pump 3 and replaced by a larger or smaller diameter in diameter. This depends on the size of the system to be cleaned or on the wear of the cavitation and high-pressure nozzles 2.

- the procedure for cleaning well systems and open, tubular containers or pipe systems is carried out in the following steps.
- the cleaning head 1 is drained via a cable or a rigid connection in the well, container or pipe system to the point where the video head 8 with the camera 15 determines the transition from the well pipe to the slot bridge filter 12 or a surface to be cleaned and the cleaning head 1 with the cavitation and high-pressure nozzles 2 is located opposite the surface to be cleaned. Subsequently, the cavitation and high-pressure nozzles 2 are aligned so that the
- Cavitation and high-pressure nozzles 2 are directed perpendicular to the surface to be cleaned or at a defined angle to the surface to be cleaned and the cavitation and high-pressure nozzles 2 are at an optimum distance from the surface to be cleaned.

Abstract
L'invention vise à proposer un dispositif ainsi qu'un procédé afférent qui permettent, dans des systèmes fluidiques ouverts existants, par exemple des systèmes de puits ou des réservoirs tubulaires ouverts ou des systèmes de canalisation, d'éliminer de manière fiable et à moindre coût les incrustations, dépôts et microfilms présents dans les composants du système et de les évacuer hors des composants du système vers l'extérieur du système. Le système de nettoyage de puits est composé d'une tête de nettoyage ronde (1) adaptée au diamètre du puits ou du réservoir et comportant sur sa circonférence extérieure des buses à cavitation et haute pression (2), au-dessus de laquelle est agencée une pompe à eau contaminée (3) reliée mécaniquement à la tête de nettoyage (1) et dont l'ouverture d'aspiration se trouve au centre à l'intérieur d'un capot de protection (4) et qui est munie d'une évacuation (5) de l'eau contaminée en direction d'un réservoir collecteur. Ledit capot de protection (4) présente une fente d'aspiration (6) périphérique par rapport à la tête de nettoyage (1), et les buses à cavitation et haute pression (2) de la tête de nettoyage (1) sont reliées à une pompe haute pression (13) externe par une conduite haute pression (7), et sous la tête de nettoyage (1) sont agencés une tête vidéo (8) munie d'une caméra (15) et plus bas un panier perforé de réception (9) adapté au diamètre du puits ou du réservoir, des conduites d'alimentation en énergie et de commande allant des composants correspondants, par exemple la pompe à eau contaminée (3), jusqu'à un pupitre de commande externe du puits ou du système à nettoyer. Le procédé de nettoyage de systèmes de puits consiste à lâcher la tête de nettoyage (1) dans le puits par l'intermédiaire d'un câble. La pompe haute pression (13) et la pompe à eau contaminée (3) sont ensuite mises en marche simultanément, et les buses à cavitation et haute pression (2) sont ainsi également activées. Une aspiration des impuretés et des particules enlevées est effectuée directement dans la zone des buses à cavitation et haute pression (2) par l'aspiration (6) de l'eau contaminée. Seules les particules grandes et lourdes tombent en direction du panier perforé de réception (9) et sont reçues par le panier perforé de réception (9).
