    RAY TRANSMITTER DEVICE BETWEEN THE ROTOR AND THE GONDOLA IN A
    AEROGENERATOR
    TECHNICAL FIELD OF THE INVENTION
    The present invention relates to a light transmitting device between the rotor and the gondola, configured to be installed in a wind turbine, and the associated installation procedure; which are located within the renewable energy sector of the wind type, as well as in the management and electrical conduction of lightning caused by thunderstorms to land.
    The main purpose of the lightning transmitting device of the invention is to be able to protect sensitive parts of the wind turbine from over-intensities in its main entities, which originate through rays that can fall on said wind turbine, and that cover part of it. Until reaching land. This protection is carried out thanks to a simple, versatile lightning transmitter device, which has an ideal installation facility for the diverse conditions existing at the location of each wind turbine; and that guarantees the correct transmission of the electric current, from the rotor of the wind turbine to the gondola, of the wind turbine (without passing through the blade bearing, bushing and rest of the wind turbine's power train) and from this to ground, in a way safe and effective
    BACKGROUND OF THE INVENTION
    By way of introduction, the variety of locations of wind turbines used in the transformation of wind energy into electrical energy is known, which are located in strategic areas and deprived of physical obstacles in order to maximize wind energy from the wind, see for example mountain tops, sea areas, etc.
    This location in exposed areas and the geometry of the wind turbines, which corresponds to a mast anchored by its base to the ground, and in its upper part there is a bushing from which three or more blades of aerodynamic profile start; makes the probability of attracting lightning be high, and once a beam reaches the wind turbine itself, there is a large current, capable of damaging part of the internal components of the wind turbine itself, with the consequent damage to the company electricity supplier, and the risk for operators to change these deteriorated components in situ according to the extreme locations of the wind turbines themselves. The most critical point of transmission of the beam to the ground occurs when the beam falls on the moving blades and the beam must be transferred to the gondola of the wind turbine itself that remains static, so a link between the moving blades must be available and the static gondola that transmits said ray to earth and that does not affect the normal operation of the blades.
    To solve this problem, a system of protection of the components of the wind turbine against lightning strikes is known, which consists in directing the discharge from the tip of the blade or shovel to the ground, using first an internal cable that joins the tip of the blades, supported on the internal stiffening beam of the blade to subsequently conduct said electric current to the bushing through the blade bearing, and from there to the low speed shaft. It then arrives at the frame through the bearings and, finally, through the rotating crown that joins the frame with the tower, the discharge is carried to the ground. But this solution has the great disadvantage that lightning strikes along this road damages the bearings and the low train, so alternative solutions have been sought.
    In this regard, the patent application of the applicant himself, of publication number ES-2265776, which describes a light transmitting device, which is formed by a first conductive bar fixed to a second insulating bar, and fixed to a wind turbine hub. Thus, a first end of the lightning transmitting device faces a metal band located at the root of each wind turbine blade at a first distance that allows an electric jump of an incident beam at a tip of a wind turbine blade, while a second end faces a gutter of a wind turbine gondola at a second distance that allows the lightning to jump. In this way, the beam is driven from the blade tip where it hits the ground, through a series of conduction means that include the lightning transmitting device, avoiding said means that the beam affects the sensitive parts of the wind turbine.
    This solution guarantees the non-deterioration of the main components of the wind turbine; but it presents an inconvenience mainly referred to the assembly and installation of said light transmitting device with respect to the blade and the water spill; since so that the
    transmission of the beam to the ground is carried out in an optimal way, it is necessary to guarantee predefined and concrete distances between the ends of the conductive bar and the band of the blade and the water slide respectively, without coming into direct contact between them; for this, the transmitter device has to be placed very precisely, since if the distance between the metal band of the blade and the end of the bar, or between the other end of the bar and the water drain is excessive, the tension required to that the electric arc jumps between them increases and may cease to function properly, jumping the arc to other nearby metallic elements of the wind turbine itself, with the consequent problem that this entails. This distance is also affected by the manufacturing tolerances of the shovel and the gutter.
    It should be noted that there are also light transmitting devices with direct contact between the blade (which rotates on its axis and in turn rotates with the bushing) and the gutter (static), but these generate welding problems when a high current passes, generating excessive noise due to friction between components, in addition to requiring frequent maintenance due to wear due to friction between moving and fixed parts.
    That is why, in view of the inconvenience existing during the assembly and guarantee of the predefined distances for the electric arc to jump between the metal band of the blade, the conductive bar, and the water spill, the appearance of a new lightning transmitting device capable of being installed in any type of wind turbine, which allows its adaptability to the variability in the distances between the metal bands of the blades and the pouring element, and that guarantees at all times the correct electrical conduction between the two elements when a beam reaches the wind turbine structure through its respective blades; and all this with a simple transmitter device, easy installation and maintenance, and economically competitive with regard to the state of the art known to date. DESCRIPTION OF THE INVENTION
    The present invention relates to a light-transmitting device between the rotor and the gondola of the wind turbine, configured to be installed in a wind turbine of blades that rotate with respect to a hub, where said wind turbine additionally comprises a gutter element, so that the Transmitter device comprises the following main entities:
    - A first electrically conductive plate, where one of its ends is separated a distance from a metal band located at a root of each blade; - a second conductive plate of electricity, where one of its ends is separated a distance from the pouring element of said wind turbine; -medical conductors of electricity between the first and second plate; - an electrical insulator coupled to said first and second conductive plates; wherein said insulator is in turn coupled to the hub of said wind turbine; and - means of relative displacement between the first and second plate, said means configured to guarantee a predefined distance between the end of the first plate and the metal band located at the root of each blade; and between the end of the second plate and the pouring element.
    It should be noted that the separation distance between one of the ends of the first plate and the metal band · located at a root of each blade; and the distance of separation between one of the ends of the second plate and the pouring element of said wind turbine; It is one that guarantees the creation of a sufficient electric arc so that the electric current passes from the metal band to the water spill element through both plates.
    Clarify also that the concept of plates refers to any type of metal piece of substantially rectangular geometry and has a reduced thickness, its variable section being able to be circular, bar type, or rectangular, prism type, etc.
    In view of the main entities of the transmitting device, the following developments are observed with respect to the state of the existing art, and in particular based on the lightning transmitting device described in patent application publication number ES2265776; since in the transmitter device object of the invention, the existence of two plates electrically connected to each other is described by means of electrically conductive means; in this way, when the number of conductors becomes independent in two plates, it is possible to accurately position the location of the first end of the first plate with respect to a metal band located at a root of each blade; and the second end of the second plate with respect to the water spill. And for this reason, it is possible to maintain at all times an exact distance between the elements that are part of the electric path of the current coming from the electric beam, ensuring that the electric arc circulates where it is intended to circulate, until it reaches the ground through the water spill described.
    Additionally, it is described that both plates are coupled, directly or indirectly, to an electrical insulator, which in turn is coupled, again directly or indirectly, to the corresponding wind turbine hub. In this way, the electrical insulator guarantees the impediment of the passage of current from the first plate to the bushing; avoiding the deterioration of the bearings and other mobile elements of said wind turbine.
    In relation to the means of relative displacement between the first and second plate, remembering that they are configured to guarantee a predefined distance between the end of the first plate and the metal band located at the root of each blade; and between the end of the second plate and the pouring element; Two preferred possibilities of realization are contemplated:
    A) The first embodiment describes the possibility that the relative displacement means between both plates comprise: - An oblong groove belonging to the second plate, and - at least a first hole belonging to the first plate, which is located internally with with respect to the projection of the oblong groove of the second plate on the first plate; and where at least one fixation is coupled respectively to the groove and the hole, allowing the relative position between both plates to be modified depending on the length of said groove.
    It is noted that the oblong groove of the second plate ensures that the distance between the ends of flat tracks can be modified, which is directly related to the length of the oblong groove itself, being a simple and versatile solution for each type of installation; being able to describe a procedure for installing the light transmitting device, which comprises the following steps: a) Position the first plate at a certain distance with respect to the metal band located at the root of each blade; b) position the second plate at a certain distance from the element
    watersheds of said wind turbine;
    c) fixing, by means of said, at least one, fixing, both plates through the part overlapof the first plate with respect to the second plate, through the oblong groove of thesecond plate and said, at least one, hole of the first plate.
    Noting that, in this alternative embodiment, the conductive means of theelectricity between the first and second plate are the plates themselves, being in contactbetween them thanks to said, at least one, fixation.
    Also, and in order to position the two plates with respect to the electrical insulator,the possibility is described in which the first plate has a tear configured forallow the fixing of said plate with respect to a support, which is in turn coupledto the electrical insulator; and the second plate has a tear also configured forallow the fixing of said plate with respect to the support.
    Again, said fixing embodiment is associated with an installation procedure of thelightning transmitting device object of the invention, which comprises the followingstages:d) fix, through a first fixing element, the first plate with respect to the supportthrough the corresponding tearing of said first plate; Ye) fix, through a second fixing element, the second plate with respect to thesupport through the corresponding tearing of said second plate.
    In this way, to ensure all the installation and exact location of the devicetransmitter in said first alternative, it is necessary to set the distances betweenthe conductive elements of the metal band and the water slide with respect to theends of the first and second plate, then, on the other hand, fix bothwith respect to the support coupled to the electrical insulator.
    B) The second embodiment describes the possibility that the displacement meansRelative between both plates include:-A first elastic spring coupled on one side to the first plate, and on the other hand to theinsulating;-a second elastic spring coupled on one side to the second plate, and on the other hand to theinsulating;- an electrical conductor cable coupled to both the first plate and the second plate,
    and -where at each end of each plate closest to the metal band and to the pouring element respectively, insulating elements configured to come into contact in said metal strip and the pouring element are located respectively thanks to the elastic force of two elastic springs; and configured said insulating elements to avoid contact between the ends of the plates and the metal band and to the pouring element respectively.
    Substantial differences are observed with respect to the first alternative of realization of the displacement means, since in this case the existence of oblong fixations or grooves is not contemplated to define the exact distance between the end of the first plate and the metal band. of the shovel, and between the end of the second deck and the water slide; since in this second alternative it is the insulators associated with said plates, who, once in contact with said metal band and the water slide respectively, manage to guarantee at all times the exact distance to achieve the desired electric arc.
    In this regard, and in relation to said second alternative, an installation procedure of the lightning transmitting device is described, which comprises the following steps: a) Fix one end of the first plate at a predefined distance with one of the insulating elements, said end being embedded with respect to the insulating element; b) fixing one end of the second plate at a predetermined distance with respect to another of the insulating elements, said end remaining embedded with respect to the insulating element; c) fix the respective elastic springs to each end of each plate opposite the respective insulating elements; d) attach the elastic springs to the insulator; e) connect each plate through the electrical conductor cable; and f) positioning the transmitting device between the metal band of the root of each blade and the water spill element of said wind turbine, until one of the insulating elements with said metal band comes into contact, and the other insulating element with the water spill element, due to the elastic springs associated with the plates fixed to each said insulating element.
    It is observed that in this second alternative, there is permanent contact between the
    insulating elements and the corresponding metal band of the shovel and the gutter; and therefore there may be wear of said insulating elements that requires periodic maintenance of greater frequency than in relation to the first alternative; but that as an advantage over this one it is observed that the distance between the ends of the plates and the metal band of the blade and the water slide is always constant, being predefined in stages a) and b) of the associated procedure. On the other hand, since there is no direct contact between the plates and the blade band and the water slide respectively, no welding points will occur when the beam passes, which does happen with the systems based on direct contact. Finally, the insulating material is selected to have high friction resistance and low coefficient of friction, to reduce possible noise and wear.
    Finally, and in relation to both alternative embodiments, the preferred option is described in which the electrical insulator is coupled to the wind turbine hub through a base that has relative displacement means between the electrical insulator and the wind turbine bushing. . Allowing a greater degree of installation flexibility in order to absorb geometry errors or installation of the elements adjacent to the lightning transmitting device object of the invention.
    Said displacement means can comprise a plurality of oblong grooves configured to allow coupling between said base and the bushing through respective fixing means; where said oblong grooves are positioned in the same height adjustment direction of the lightning transmitting device itself; In this way, a method of height adjustment of the light transmitting device is described, which comprises coupling the electrical insulator with respect to the wind turbine hub, through the means of relative displacement between both elements mentioned above.
    Thus, with the proposed invention, a light transmitting device is obtained that is capable of being able to protect the wind generator from overcurrents in its main entities, and caused by atmospheric rays that can fall on said wind turbine; thanks to a simple, versatile lightning transmitting device, which has an ideal installation facility for the diverse conditions existing at the location of each wind turbine; and that guarantees the correct transmission of the electric current from the origin to earth in a safe and efficient way.
