    AEROTRANSPORTABLE PRESSURE LIQUID LAUNCH DEVICE
    The object of the present invention is a device
    5 airborne launching of liquid under pressure, for the cleaning of wind and photovoltaic installations that, in addition, can be used for extinguishing fires, by projecting high-pressure liquid products from an aircraft, preferably a take-off and landing aircraft vertical
    10 (piloted or not) and that has the particularity of being configured as an external load to the aircraft itself, so it is not necessary to be approved as a on-board device.
    State of the art
    15 The loss of wind turbine production due to the so-called aerodynamic profile breakage is well known to those skilled in the art. This happens when the environmental dirt produced by dust, humidity, pollution, impact of insects and absence of rain during a certain period of time cause that breakage 20 of the profile and the weight accumulated on the surface of the blades cause production losses that They are estimated between 5% and 25%. In the same way. It is sufficiently proven that, after an effective cleaning, the productive values return to their original state, as can be read in [Double Stall. C. Bak et al. Riso National Laboratory, 25 Roskilde, June 1998, ISBN 87-550-2417-3) or in [Dust effect of the Performance of Wind Turbine Airfoils. N. Ren et al. Journal of Electromagnetic Analysis & Applications, 2009, 1: 102-107, June 2009). Wind turbine blades cleaning, traditionally. it is done manually, with lifting cranes regardless of
    30 the structures of the wind turbine or by means of a lifting system with shovels through the rotor, in physical contact with moving elements of the turbine. This system is slow, expensive, requires more labor and carries risks for both personnel and the wind turbine structure.
    35 There is also an automatic method by means of pipes fixed to

    the structure emitting a jet of water with detergents at 50 bar pressure for a considerable time while the blades rotate. In this way we try to simulate the cleaning effects of rain. This method, however, does not attack all the angles of the blades with the same effectiveness, nl. the front face of the blades that are precisely the ones that need more clean surface. The amount of water used is high and its implementation and cost is considerable.
    Therefore, the maintenance of wind turbines is a necessity fully admitted within the operational costs and that it is necessary to reduce to increase profitability, since the methods currently known are slow, expensive and with a high risk of the personnel in charge of performing cleaning operations such as the scrito system at: http://www.pro-bel.ca/ProductsAndServicesBJadeAccessEq u¡pment.html
    Also known are US2013133199 or ES2381351 based on the modification of the blade itself, which is impracticable for installed wind turbines.
    On the other hand, helicopter cleaning is widely used in high voltage insulators. Document W02011042011 describes a pressure water cleaning system with helicopters especially suitable for high voltage insulators. However, this helicopter cleaning method, as well as other known ones (FR2586194, IT1244559, GB2261772 or JPH0268297 j, are not directly applicable to the cleaning of wind turbine blades. of the pressures of exit of the water, an adaptation of the angle of attack, a rotation of the exit nozzle and of the set of the pole to obtain some times of profitable and safe execution.In addition, it is necessary to bear in mind that the wind turbines are Windy areas, unlike most high-voltage lines, which contributes significantly to the accuracy of cleaning and requires a solution of its own.
    On the other hand, the existence of offshore wind fields is increasingly common, in which the use of traditional cleaning systems (such as pumper trucks) is impossible, and in

    which bemakeyetplusnecessaryheusefromsystemsfromcleaning
    Airborne
    Further, therequirementslegalinhow muchtothesystems
    Airborne make any possibility of using some systems in other applications totally disposable. That is to say, that the aeronautical norm demands that, for each application, the systems are validated, with what an expert in the matter would discard the direct application of the systems for cleaning of insulators.
    Wind turbine blade cleaning systems are known in the state of the art, at least from DEI02009048778, which describes a cleaning apparatus based on a multipurpose helicopter comprising a tank with a cleaning liquid, as well as a support frame that is attached to the helicopter by one side. The cleaning equipment also includes a mobile washing lance that allows the pressure washing liquid to be directed against the wind turbine blades.
    Document DEI02010048400 describes, on the other hand, a method used to check the structural state of wind turbines turbines. US2006237558 describes, on the other hand, a sprayer for use in helicopter type aircraft. US4477289 also describes an airborne helicopter system for cleaning the insulators in medium and high voltage lines.
    As already mentioned and, in conclusion, the aeronautical regulations for on-board systems are very strict (especially in the European Union "EASA" and the United States "FAA", among others). In fact, all on-board systems require strict homologation procedures (STC) for each different type of aircraft. Thus, the previous cleaning systems, if for example one of them is approved for a Bell212 type helicopter, could never be directly disassembled and mounted on another type of helicopter, even belonging to the same manufacturer (such as a Bell -222) without previously requiring technical-legal approval that, where appropriate, may impose restrictions on use

    and designs impossible to assume, technically and economically _ Even on the same helicopter model, but with European registration, it would not be valid with other countries such as the US.
    Therefore, against the systems described, the need for a system that is not dependent on the type of aircraft used is imposed.
    Description of the invention
    It is an object of the present invention, an airborne device for releasing pressurized liquid, according to the first claim that accompanies the present specification. Particular embodiments of the invention are described in dependent claims.
    Thanks to this device, it is possible to separate the device from the aircraft used since, being transported externally, in the same way as a cargo basket, it does not need any type of approval, but simply comply with the specifications of the baskets for each helicopter (i. e. weight, centering, center of gravity and essentially dimensions) marked by its manufacturer and / or aircraft operator. Thus, its treatment is not that of an on-board system, but that of an external load.
    Another advantage over the prior art is that the device is operated remotely, that is, unlike in the cited documents, the operator is housed inside the cabin of the aircraft or, if the aircraft is unmanned , from the ground control console itself.
    The present invention aims at washing blades and wind turbine structures. Currently, the cleaning of wind structures is done from ropes or by lowering a basket along the mast, taking on average 1.5 days to complete the cleaning process of the structure, with the consequent loss of production and risk for Workers . In the face of these systems, the present invention allows cleaning the same structure in approximately 10-20 minutes using detergents.
    s

    biodegradable _ If, in addition, it is desired to proceed in defrosting operations, the device of the invention optionally has a heating unit by pellet burner configured to heat the water to approximately 80 ° C which is subsequently mixed with antifreeze. In these cases, it is possible to increase the productivity of the wind farm by 100% and reduce the use of fossil energies to cover periods of inactivity.
    Also, simultaneously, it incorporates a gyro-stabilized filming system that allows the thorough inspection of the structures by means of high resolution video and thermographic equipment, thus avoiding the extra costs of having to hire another supplier to perform Periodic inspection
    It is another object of the present invention to provide a device for washing and inspecting photovoltaic installations. Pollution, dust or saltpeter are elements that reduce the solar collection capacity of the panels, which causes yield losses. Periodically, it is necessary to proceed to the washing of the photovoltaic panels, but in those facilities that have a large number of panels, cleaning becomes a very slow, difficult and expensive task. However, thanks to the invention, as with wind farms, it is possible to reduce cleaning costs and exponentially increase the performance of the facilities. In addition, the panels are simultaneously visual, HD and IR inspected, thus avoiding the cost overrun of an inspection company.
    Another object of the present invention is the washing of insulators and simultaneous inspection of high voltage lines. The current insulator cleaning equipment with helicopters that currently exist
    (in practice, only two helicopter models) have a number of drawbacks: the distance of the cleaning water jet is 1.5 meters; They are only approved for two helicopter models; it is necessary to keep the helicopter door open so that the operator can use the cleaning device; the cleaning equipment is attached to the chassis of the helicopter which

    hinders the position of the helicopter with respect to the wind; there is a constant danger due to the proximity of the operation to the lines; the
    systems currentThey areunablefromto washheinsulatorcentralinthe
    most fromlines ofhightension
    Do not however,Thank youtothePresentinventionbeget
    to solve these problems, adding, in addition, the possibility of using biodegradable and dielectric detergent, as well as performing the thermo-graphic and visual inspection in high definition simultaneously, avoiding to hire two separate services.
    It is another object of the present invention to fight fires in urban and forestry areas. Thanks to the present invention, it is possible that a helicopter is able to enter urban areas for firefighting reaching heights that the current stairs or fire cranes are unable to operate. At the same time, the device of the invention records and retransmits live images thanks to its gyro-stabilized filming system and thermal imager that allows, even through smoke, to distinguish the existence of people in a passenger compartment or inform, by time that attacks the fire, of the hottest points in the area. In addition, in forested areas it will allow the directional firing of liquids or the complete emptying of the tank.
    Throughout the description and the claims the word "comprises" and its variants are not intended to exclude other technical characteristics, additives, components or steps. For those skilled in the art, other objects, advantages and features of the invention will be derived partly from the description and partly from the practice of the invention.
