    which allows cleaning actions to be carried out by means of an unmanned aerial vehicle that accesses elevated areas safely and easily.
    This device can perform the previously programmed cleaning actions in a supervised or fully automatic manner, so that dirt is removed effectively before the accumulated layer is too thick. 5
    EXPLANATION OF THE INVENTION
    The cleaning drone is an unmanned aerial vehicle specifically designed for dry cleaning of hard-to-reach areas. Its low cost and simple operation make it an ideal solution both for the conservation of historic buildings of high heritage value, as well as for use in other buildings of lower artistic value (such as industrial buildings, warehouses, concert halls, stations of meter, etc.) that due to their characteristics tend to accumulate large amounts of dust and grease in hard to reach places.
    The cleaning drone is composed of a main body that has a series of 15 sensors, a control system and a set of mechanisms that allow the aircraft to be raised and placed in the desired position and also provides and transmits the movement to the instruments of cleaning that fit into said main body. Therefore, the cleaning instruments move in solidarity with the actuators and are not simply transported by the drone. twenty
    Thus, the cleaning drone has as one of its distinguishing features the integration of a greater number of actuators than those strictly necessary to maintain the support and stability of the device. Such actuators (both strictly necessary and additional), are typically formed by electric motors that can optionally have a propeller that acts as a propeller in their rotor. 25 Actuators or motors have at least one terminal for attaching supplementary instruments that are driven in the same way as the mobile elements that they keep in the drone in the air during use.
    The cleaning instruments have a modular character to provide the drone with greater versatility and facilitate replacement when they have reached the end of their useful life due to wear and tear.
    Depending on the conservation or cleaning action to be carried out, a certain configuration of the design of the central body and instrument assembly may be more appropriate.
    Despite the reduced autonomy of multicopters, they allow cleaning actions both inside and outside buildings, thanks to the excellent maneuverability of the coordination of their electric motors, which in turn allows overcome the effect of air currents in its trajectory.
    For example, for cleaning roofs, the multi-helicopter cleaning drone, which has a supplementary motor in the central area of the main body, of which a stem with a cleaning instrument that rotates at its end 10 is particularly convenient. Said element is not intended to keep the drone in the air, but to clean the surfaces that lightly rubs in its path when the operator approaches a surface.
    A possible variant of this example would have a cleaning instrument attached to each of the propellers of the multicopter, instead of a single instrument in the central motor. This variant reaches locations on the lateral ends of the drone with greater ease. In addition, the alternating direction in the rotation of the motors allows the cleaning instruments to act with opposite movements, which favors the removal of dirt with their friction.
    In addition, the design of the cleaning drone allows the use of instruments that eliminate dust and other types of impurities without contact, for example bars loaded with static electricity 20 that attract the suspended elements due to the action of the propellers. The loading of the bars can be carried out with the help of friction produced by the motors to which a mechanism similar to that of a Van Der Graaff generator has been coupled. It is possible that the drone operator periodically unloads the bars by placing the drone on a base with a ground connection. 25
    The examples described are intended to give a perspective of the multiple possibilities offered by the present invention, its broader spirit being encompassing many other possible configurations.
    Next, the present invention is detailed in correspondence with the preferred embodiment of the cleaning drone and in reference to the figures accompanying the application. In the description that follows, the numerous specific details are set forth with the intention of providing a complete understanding of the invention.
    However, it will be obvious to the technical experts that the present invention can be implemented without these specific details. In addition, on the other hand, some well-known structures are not shown in detail (such as the electronics of the control system), in order to avoid unnecessary darkness and a loss of focus on the description. 5
    BRIEF DESCRIPTION OF THE DRAWINGS
    To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, a set of drawings is attached as an integral part of said description, where, for illustrative purposes and not limitation, it has been represented the following:
    Figure 1.- Schematically shows a bottom perspective view of a possible embodiment of the multi-helicopter cleaner drone (1). Since the illustrated case has four propellers (8), externally it can look like a quadcopter; however, it has a supplementary motor (2) in the central area of the main body, from which a stem 15 (3) is attached, which is connected by means of an anchoring mechanism (in the form of a thread with a Grower-type pressure washer) ( 7) with a cleaning instrument (4) that rotates at its end. Like any other unmanned vehicle, the cleaning drone has a control and navigation system that receives information from the sensors (5) and manages the signals that govern the actions of the actuators, which in this case are conventional electric motors.
    Figure 2.- Schematically shows a perspective view of the variant of the multi-helicopter cleaning drone (1) in which the cleaning instruments (6) are coupled by means of an anchoring mechanism (7) that in this case protrudes from the propellers (8 ).
    Figure 3.- Schematically shows a perspective view of the cleaning drone (1) 25 multicopter in which a supplementary motor (2) has been placed in the central area of the main body, which holds a cleaning instrument formed by a set of bars charged with static electricity (9) that rotates slowly to attract suspended particles.
     30 PREFERRED EMBODIMENT OF THE INVENTION
    An exemplary embodiment of the multicopter cleaner drone (1) is shown in Figure 2. The four propellers (8) keep the drone (1) in the air thanks to the rotation provided by the rotors of the motors. Said rotational movement is communicated to the cleaning instruments (6) that are attached to the axis of the rotors through the propellers (8) by means of an anchor that protrudes in the form of a rod (3), which ends in a mechanism of anchor (which in this case is threaded and secured with washers type Grower) (7), where each of the cleaning instruments (6) is attached. In this case, the instruments (6) have a padded surface, in the form of a disk, that drags the dirt particles with their friction and causes them to fall by the action of gravity. The fabric with which this instrument is coated (6) can be adapted to clean different types of dry surfaces, depending on their texture, roughness, fabric, and so on.
    In this example, the motor located in the central area (2) is not used, so that only the cleaning instruments (6) have been placed in the propeller (10) propeller (8) that 15 provide support to the assembly .
    The instruments (6) can be coupled and removed from the shafts by means of a clamping system that in this case is formed by screw-shaped terminations (7 that fit in the opposite direction of the motor rotation so that the anchor remains firm during the flight In addition, as already indicated, the thread has an anti-vibration mechanism (with Grower type washers) that ensures the fastening of the bolted joint and a uniform distribution of the forces transmitted to the cleaning instrument.
    There are many possible configurations that, in the form of embodiments, fall within the essence of the invention. All of them having in common that the cleaning instruments are not simply carried by the drone, but move in solidarity with the propulsion systems and additional rotary motors that it incorporates.
    For example, a variant is shown in Figure 3 in which the instrument is formed by a set of electrostatically charged bars (9), which attract small particles in suspension. Logically, the speed of rotation of the supplementary motors (2) is adjustable from the control system, and with it the rotation of the corresponding cleaning instruments (9), in accordance with the cleaning operation to be performed and the cleaning head per se.
    The materials used in the manufacture of the different elements that compose it, as well as the shapes, dimensions and accessories that it may present, will be independent of the object of the present invention, being able to be replaced by other technically equivalent ones, provided they do not affect the Essentiality thereof or depart from the scope defined in the claims section. 5
    Once the concept expressed has been established, the claims note is written below, thus summarizing the novelties that are to be claimed.
