    2 °) ES-1070127_U: This invention, as indicated in its statement, has as its object the presentation of a device composed of guides in vertical or horizontal arrangement on which a cleaning carriage that moves by means of motors with a reducer, which transmits its turn to their respective pulleys by dragging of toothed belts, transmission chains or toothed rack. On the other hand, another reduction motor rotates a cleaning roller located with the profile of the cleaning car in contact with the outside of the solar panel; The roller is impregnated with cleaning liquid so that when the car is raised and lowered, the cleaning roller sweeps the solar panel with one or more scrapers and an air-drying complement. At the end of the descent, the remaining liquids are collected in a continuation tray of the profile of the cleaning car that has drain holes.
    3 °) ES-1074781_U: the object of the invention is centered on a vehicle which incorporates a series of elements intended to clean the upper surface of the solar energy collection panels, especially those installed in solar fields, in order to increase their performance, presenting the particularity of incorporating, on the one hand, means to effectively control the approximation of the cleaning brush or cylinder that it has, to the surface of the panels and to maintain its position even if the vehicle travels through uneven terrain, and on the other hand, means to ensure the immediate drying of the panels after cleaning them.
    4 °) WO2010079242A1, procedure for cleaning solar panels, characterized by the projection of water vapor in the form of multiple individual jets at a pressure and temperature conditional on the resistance characteristics of the solar panel to be cleaned and the impurities to be removed, and according to an adjustable angle with respect to the panel, variable according to the type of impurities to be removed, approximately between 30 ° and 90 °, with variable steam temperature between 150 ° C and 200 ° C, variable pressure between 2.5bar and 5 bars, performing gentle contact cleaning in addition to steam jet projection.

    DESCRIPTION OF A PREFERRED EMBODIMENT
    The solar concentrator panel cleaning device equipped for water saving will include three accessory elements, all of which can be implanted working together or only some of them.
    For the purposes of the present preferred embodiment, and in relation to the configuration that includes all the saving systems, the construction of the mirror cleaning equipment in concentration camps will include the elements described below.
    By means of bolted joints, a pair of articulated bars are fixed, which act as a support arm support for flexible sweeping lips (01), to the main structure of the cleaning implement (05). These articulated bars will allow the final end of the supporting arm of flexible sweeping lips (01) to be brought closer to the mirror. In this final end there is a lip stiffening profile (03) on which the flexible sweeping lip (04) is fixed, the profile of which will be adapted to the section of the surface on which it will move. The end of the flexible sweeping lip (04) will be especially flexible so that it folds in contact with the mirror and during the advance of the vehicle, dragging the water existing in the mirror. The arrangement of the lip will be done not perpendicular to the direction of advance of the

    vehicle allowing the flow of collected cleaning liquid to occur in the same direction that favors the evacuation of the same (downward direction, the lip appears more and more delayed as the height decreases).
    By means of bolted joints that allow rotation, fixing is made to the main structure of the cleaning implement (05) of an articulated bar in whose opposite end another similar or similar bar is arranged with the possibility of rotation, thus forming the mobile covering structure ( 06). At a point located on the second bar of the mobile cover structure (06) the rod end of the linear actuator (07) is fixed; the other end of the linear rod (7) is fixed to the main structure of the cleaning implement (5). The arrangement of the actuating elements will allow the folding of the mobile cover structure (06) to be folded behind the main structure of the cleaning implement (05) and also its extension to cover the volume contained between the main structure of the implement of cleaning (05) and the mirror, during the cleaning process when there are no obstacles to it. Attached to this mobile coverage structure (06) there are waterproof screens that allow the containment of existing water in suspension, and finally its channeling until a final process of water recycling.
    It is not considered necessary to make this description more extensive so that any person skilled in the art understands the scope of the invention and the advantages derived therefrom. The materials used, shapes, sizes, number of pieces and disposition of the elements described will be susceptible of variation as long as this does not imply an alteration in the essentiality of the invention.
