Definitions
- the invention relates to an unmanned aircraft of the remote-controlled aerogory type designed to perform measurements of electrical parameters on an object, in particular resistance measurements on buildings whose substantial height makes the checks difficult to implement. More precisely, and according to a preferred example which will be developed in more detail in the present text, the invention finds particular application in the field of wind turbines, for the control of their lightning path.
- a wind turbine must imperatively be equipped with protection against lightning strikes.
- these protections take the form of a lightning path with which all wind turbines are equipped, and which connects each blade to the ground by means of a conductive cable.
- Metal pads are installed in several places along the wind turbine blade, fixed to the surface and connected to the cable constituting said lightning path. This cable is most often made of copper, and connected to the ground at the bottom of the wind turbine.
- the failure of a lightning path is the result of either a manufacturing defect or damage resulting from a lightning strike. During a measurement, the consequence of the defect or damage is an increase in the electrical resistance of the lightning path.
- the question of the repetitively stable mechanical connection refers to the very structure of the drone and more particularly to the connection between on the one hand the element of contact at the end of an arm protruding from the perimeter of said drone and on the other hand the frame of the latter.
- the question of the electrical connection is no less important, since it must guarantee the possibility of obtaining a correct signal once a mechanical contact, more or less stable, has been established.
- the mechanical principles to which the contact element connected to the drone must subscribe are mentioned (mounting with spring means), but without description of a technical configuration which responds precisely thereto.
- the text is hardly more eloquent, contenting itself with mentioning the use of copper wool, without knowing precisely how it is installed in the configuration, which is itself described in a very general.
- One of the objectives of the invention is therefore to provide a technically successful configuration.
- an electrically conductive contact element comprising at least one conductive plate
- the electrically conductive contact element comprises a rigid support perpendicular to the connecting arm coated, at least on its face opposite said arm, with a coating of flexible conductive material.
- the support comprises an external plate whose outer face is covered with copper wool and an internal plate separated from the external plate by rods parallel to the arm allowing adjustment of the distance separating the plates, the layer of copper wool covering the outer plate extending so as to produce a flexible wall joining at least two of said rods.
- foam is interposed between the copper wool and on the one hand the external plate, and between the copper wool and on the other hand the rods joined by the copper wool, to allow any shocks to be absorbed. at the moment of contact with the blade to be measured. It also lightens the device.
- At least one wire constituting the conductive cable is fixed to the outer face of the outer plate, for example by means of metal screws whose head is on the side of said outer face.
- the external and internal supports are substantially inscribed in circles defined by three points materialized by the axes of three rods connecting them. There are therefore preferably only three rods, said circles being strictly speaking those which circumscribe the supports.
- the external support takes the form of a hollow wheel-shaped disc with an external rim in which the rods are fixed and spokes converging towards a fixing hub of the arm
- the internal plate comprises an internal shape joining the fixing zones of the rods, the center of which is provided with an orifice for the passage of the arm.
- These fixing zones are, for example, through cylinders connected in the center by arms connected to each other via curved lines.
- a protection system is provided, consisting of two rigid masts of the same length fixed to the internal plate, developing radially forming an acute angle between them, and connected near their free ends by a rigid wire. In particular, this makes it possible to measure at the blade tip contact without putting the drone at risk.
- a reinforcement mechanism of said protection system which consists of a rod running parallel to said rigid wire, integral with the outer plate and extending beyond it, at the ends of which are fixed rigid stays also fixed at the free ends of the masts.
- the electrically conductive contact element comprises at least one conductive plate constituting the rigid support, coated with an outer padded layer comprising at least one strip of flexible synthetic foam surrounded by a coating of flexible material. driver.
- the coating of the conductive plate on an external side in charge of contact with a pad of the object to be controlled, therefore comprises a particular coating which fulfills a dual function: electrical due to the conductive nature of part of the coating in contact with the conductive plate itself, and mechanical - protective of the structure which undergoes shocks at each approach - due to the use of soft foam, which is therefore resilient.
- the specific nature of the outer layer gives the assembly a possibility of first superficial absorption of the mechanical stresses which arise at the time of the first physical contacts between the drone and a pad of the object of the measurement, contacts which involve in number of cases of collisions, without the electrical connection suffering too much from a contact which may be unstable. Since it is the outer coating of the plate that achieves the first technical approach to the mechanical and electrical dual function, it is an important constituent of the contact element.
- each strip of the outer padded layer may be made of a polyether-urethane foam core covered with a fabric covering composed of densely woven polyester fibers with copper and nickel fibers.
- a fabric covering composed of densely woven polyester fibers with copper and nickel fibers.
- the conductive plate is preferably made of aluminum, the reduced weight of which is more easily transportable by a drone.
- at least one strand of the conductive cable can be fixed on one side of the conductive plate facing the frame of the aerogory, i.e. the "internal" side of the contact element.
- each pad in contact with which the measurement is taken are pushed into the outer envelope of the object, and the measurement to be performed is then more complicated.
- each pad is in practice made up of a conductive spring fixed to the plate, each spring being surrounded by a flexible conductive tape which covers it at least partially, at least a portion of said proximal springs of the plate being in contact with the conductive coating of at least one strip covering the conductive plate.
- the conductive plate is fixed, via the link mechanism, perpendicular to the link arm, the padded layer then coating one face of the conductive plate of the distal contact element of the chassis of the air gyro. It is in fact the face of the plate which is oriented towards the outside of the drone/arm/contact element assembly, and which faces the object to be measured.
- the conductive plate may however comprise two sections fixed perpendicularly to each other in L, a first section of running parallel to the axis of the arm comprising, on its inner face, the padded layer, the second section running perpendicular to the axis of the arm comprising the mechanism for connecting the conductive plate to the arm.
- the external coating is the same as in the previous configurations. The configuration allows for example an approach along the axis of a blade, which may require different guidance to obtain a more precise positioning, knowing that the movement of the drone then takes place in another direction than previously, rather perpendicular to the axis of the arm carrying the contact element.
- the mechanism for connecting the conductive plate to the arm may comprise, on the one hand, a double ball-and-socket connection sliding along the axis of the arm, and, on the other hand, first return means for the plate in a position perpendicular to the axis of the arm and second return means urging the plate into a deployed position distal to the frame.
- the conductive plate coated with the conductive padding of the invention then has 4 degrees of freedom when mechanical stresses are exerted on it, in most cases when it comes into contact with an object to be tested.
- the return means improve the contact pressure and consequently the electrical contact, making it possible to carry out the measurement under the best conditions.
- the connecting mechanism may comprise a support fixed to the conductive plate and provided with a housing for a ball joint placed at the end of a pole capable of sliding in a slider provided in the arm, said support comprising n fixing feet to which are fixed the first ends of n identical compression springs, the second ends of which are fixed to a ring fixed to the pole, according to a configuration with axial symmetry with respect to the sliding axis in the arm.
- the feet and the compression springs are four (4) in number.
- Axial symmetry means, within the meaning of the invention, that the springs fixed to the feet together exert a resultant force whose component in a plane perpendicular to the axis of the arm is zero.
- the pole may comprise, in the vicinity of the ball joint, a motorized joint operable by remote control between a rectilinear state of the pole and at least one bent state in which a section of the pole comprising the ball joint is bent relative to the rest of the pole and the arm.
- a motorized joint operable by remote control between a rectilinear state of the pole and at least one bent state in which a section of the pole comprising the ball joint is bent relative to the rest of the pole and the arm.
- connection mechanism is such that the pole can slide in a sliding tube connected to the arm of the air gyro, and it has at its end opposite the ball joint a carriage sliding on at least two shafts of a set of parallel shafts forming the arm, a plate of said arm placed in the vicinity of its proximal end of the conductive plate serving as a stop for a first interposed compression spring between said plate and the ring of the perch or the joint.
- This first spring is provided to absorb the axial components of the forces resulting from the contacts and in particular from the shocks, while guaranteeing that once past the transient mechanical effects linked to the latter, the electrical connection can be established in an optimal manner, since the contact element is then permanently pushed against the pad to be tested.
- this plate is able to slide on at least two shafts of the arm, a second compression spring being interposed between said plate and an intermediate stop fixed to the shafts of the arm.
- the two springs do not have the same stiffness, so that their mechanical effects are cumulative and act temporally in a staggered manner, their distinct absorption capacity preferably being expressed at least partially sequentially.
- Said plate can also comprise, according to the invention, the sliding tube of the pole, said tube itself being able to slide in an orifice of the intermediate stop.
- the axial guidance is therefore multiple, on the one hand for the pole in the tube and on the other hand for the tube in the orifice, reflecting the existence of the two springs of different stiffnesses which allow a differentiated control of the movements of the pole and therefore of the contact element on the one hand, and of the plate forming abutment of the first spring on the other hand.
- This sliding guidance is also dependent on the carriage, the guide of the plate, etc.
- the intermediate stop can also serve as a support for a mast at the upper end of which are secured optical means of the type at least one camera and/or at least one laser guide beam emitter.
- Camera(s) can work in combination with laser pointers designed to help the pilot better aim, in flight, at the surface patch which signals the existence of a connection with the path of lightning from a wind turbine blade. With this visual aid, said pilot can manage the approach of the target located on the object in an optimal manner.
- Figure 1 shows a schematic view of an overall system for measuring the failure of the lightning path of a wind turbine using a drone according to the invention
- Figure 2 shows in perspective view part of an arm secured to a drone and comprising a contact element according to the second variant of the invention
- Figure 3 illustrates a three-quarter front perspective view of the first contact element variant
- Figure 4 shows a rear three-quarter perspective view of said first contact element variant
- Figure 5 shows a side view of the first contact element variant
- Figure 6 illustrates a front perspective view of this first contact element variant
- Figure 7 shows in perspective the contact element of the second variant
- Figure 8 shows a digression from the second variant of contact element more particularly suitable in the case of embedded lightning path measurement pads
- Figure 9 shows a third variant of contact element for taking rather axial measurements, for example at the end of wind turbine blades
- Figure 10 illustrates a variant in which the mechanism for connecting the contact element to the arm is articulable, the articulation of which retains the straight state of the arm;
- Figure 11 shows the same variant with the arm in the bent state;
- Figure 12 shows a perspective view of part of the mechanism for connecting the contact element to the arm, more particularly comprising the ball joint and the first means for returning said plate to a position perpendicular to the axis of the arm;
- Figure 13 shows a top view of part of the mechanism for connecting the conductive plate of the second variant to the arm, illustrating more fully the second return means of the contact element, the assembly contact element/pole in rest position axially deployed; and
- FIG. 14 represents a perspective view of this mechanism, the contact element/pole assembly in the axially contracted position, when the second return means are stressed by mechanical stresses applied to the contact element.
- the complete measurement system shown very schematically comprises a drone A directed by an operator, for example by means of a CCD camera, and provided with a pole at the end of which an element contact allows the establishment of an electrical connection with a pad, in this case placed on a blade P of the wind turbine E.
- Said contact element which will be described more substantially below, must make sufficient electrical contact to perform a quality measurement capable of being exploited by a measuring instrument C which can be coupled to a computer O on which runs an application specifically provided for the processing of the measured signals.
- the measurement and exploitation of the results therefore remain in the hands of an operator in charge of carrying out the operations to check the validity of the lightning path, who remains at the bottom of the mast of the wind turbine E, and who can, if necessary be the one piloting the drone A.
- the measuring instrument is connected on the one hand to the mass at the bottom of the wind turbine E, and on the other hand to a cable which comes from the flying machine A and is electrically connected to the lightning path via the electrical connection established through the drone A with the contact point on the wind turbine E.
- the contact element 10, as shown in particular in Figures 2 to 9 comprises in its second variant a plate 11 coated, on its face opposite the arm 40, with a padded layer 12 consisting of a plurality of strips 13 whose core is made of flexible synthetic foam, for example polyether-urethane.
- This core is surrounded by an equally flexible fabric covering, for example composed polyester fibers woven with copper and nickel fibers, metal fibers that make it conductive. All these strips 13, individually and collectively, conduct electricity to the plate 11, on which they are for example glued by means of a conductive adhesive.
- all the strips 13, the free surfaces of which are intended to be potentially in contact with the object to be measured, can come into contact with, for example, a surface patch of a wind turbine blade P E connected to a lightning path, as in the example of FIG. 1.
- the effective contact zone therefore forms an electrical connection with a cable which connects the contact element 10 with the measuring instruments C, also connected to ground to complete the circuit.
- Figures 3 to 6 show the first variant of contact element 100, having conductive copper wool in coatings 101, 102 in two orientations, which are electrically and preferably mechanically connected.
- the coating part 101 of copper wool is arranged on the external plate 110, which is connected to an internal plate 120 via three rods 130. Foam is interposed between the support and the copper wool, and also between the rods 130 involved and the copper wool covering them.
- the plates 110, 120 are not made of conductive material. The distance of the two plates 101, 102 is adjustable in the direction of these rods 130.
- At least one wire (not shown) constituting the aforementioned connection cable is electrically connected to the copper wool, for example by means of a metal screw screwed into the external face of the plate 110, said wire being attached between the head of the screw and the external face of the plate 110.
- the cable Preferably, provision has been made for the cable to consist of three screws.
- this contact element 100 has a protection system making it possible to prevent the blade on which the measurement is carried out from damaging the rotors of the drone in particular.
- This system has two masts 200, 201 at the ends of which are protection balls 210, 211, connected by a rigid wire 212 which bars access to the blade if it starts moving.
- An additional mechanism for reinforcing the protection system is provided within the scope of the invention. It comprises a rod 220 running parallel to said rigid wire 212, which is fixed so secured to the outer plate 110, on its inner face, and protrudes from it on each side.
- Rigid stays 221, 222, also fixed to the protective balls 210, 211 of the masts 200, 201, are fixed via other balls 223, 224.
- the assembly forms a protective structure which preserves the integrity of the drone from the invention even in the event of movement of the blade of the wind turbine.
- the two masts 200, 201 are actually oriented upwards, when the drone is in flight, and form a triangle with the rigid wire 212, a triangle whose apex is downwards, in the vicinity of the arm 21 or the lower stem 130.
- the contact element 10 of the second variant of Figure 7 is standard, while it includes additional components in the configuration of Figure 8: conductive protrusions 14 developing parallel to the axis of the arm 40 , and which are for example and preferably made in the form of elastically deformable pads 14, at least in the axis of the arm 40, for example springs covered with a conductive tape.
- conductive pads 14 have a deformability which makes the outer surface of the padding 12, when it is embellished with said pads 14, able to touch the pads pressed into a surface and to make an appropriate electrical connection there, making the contact element 10 effective even when the test pellets are not flush with the surface of the object to be tested, for example a wind turbine blade P E.
- the conductive plate 11 consists of an L, which means that it comprises two sections 11' and 11” fixed perpendicularly to each other, so to allow approaches adapted to geometries, for example of blade tips P.
- a first face 11' of plate 11 is oriented substantially parallel to the axis of arm 40. It is this face 11' which has on its inner face, i.e. the face of the interior volume partially delimited by the two panels 11' and 11 the padded layer 12.
- the second panel 11" is therefore oriented substantially perpendicular to the axis of the arm 40, and includes the mechanism for connecting this part 11" of the conductive plate 11 to the arm 40, which will be explained in more detail below.
- Figures 10 and 11 illustrate the existence of a joint 60 placed on the pole 21 in the vicinity of the ball joint 22 and the ring 25, which therefore divides the pole between a main section 21 and a section of end 21 'which can be arranged in an angled manner, as shown in Figure 11 in a configuration provided with the variant of the contact element 10 with deformable rods 14 of Figure 4.
- the purely rectilinear configuration of Figure 10, with the contact element variant 10 of Figure 7, allows operation such as devices without articulation 60.
- This articulation is motorized, that is to say it can be controlled remotely, from the operator placed for example at the bottom of a wind turbine E, which can give it an angle depending on the configuration of the object to be controlled. This angle is arbitrary, the adjustment being continuous in an angular interval depending on the configuration of the joint 60.
- the angular sector covered by said joint 60 is of the order of 90°.
- Figure 12 shows more precisely the connection mechanism with four degrees of freedom which connects the contact element 10 to the arm 40, the understanding of which also results from Figures 2, 10 to 14.
- a support 20 is fixed to the aluminum conductive plate 11, a central sleeve of which includes a housing for a ball joint 22 constituting the end of a pole 21 arranged to slide in the arm 40.
- This support 20 also comprises four feet 23 for fixing to the plate 11, the free ends of which have means for fixing compression springs 24 which are otherwise identical fixed to a ring 25 of the pole 21.
- the assembly has a symmetry with respect to the axis of the arm 40, necessary to guarantee the permanent return of the pole 21 to the rest position perpendicular to the plate 11.
- the sliding mechanism of the pole 21 in the arm 40 comprises a sliding tube 30 secured to a plate 31 movable in translation on three shafts 41, 42 , 43 forming the arm 40.
- a first compression spring 33 is placed between the ring 25 and the plate 31.
- a second compression spring 34 is interposed between the plate 31 and an intermediate stop 35, comprising an orifice in which the tube 30 is able to slide freely.
- the pole 21 is fixed, at its end opposite the ball joint 22, to a carriage 36 sliding on the shafts 41, 42 of the arm 40.
- the operation of the sliding controlled by the compression springs 33, 34 is then the following: when a stress is exerted on the contact element 10, for example at the time of contact with the pellet of a wind turbine blade P E, the component of this stress of appearance parallel to the axis of the arm 40 causes said contact element 10 to move towards the frame of the drone A, the drone A/arm 40/contact element 10 assembly then undergoing retraction.
- the force applied to the contact element 10 is absorbed by the springs 33, 34, which can if necessary contract sequentially, due to their different stiffness, depending on the intensity of the stress.
- the pole 21 slides in the tube 30, which provides some guidance for said sliding, the main guidance of which is however provided by the carriage 36 which slides on the shafts 41, 42 of the arm 40.
- the spring 34 contracts, and the plate 31 moves: this is what is illustrated in Figure 14.
- the tube 30 moves in an orifice of the intermediate stop 35.
- the spring 33 is also stressed in compression. Since the stresses applied to the contact element 10 are rarely only oriented along the axis of the arm, other stress components apply, which result in the ball joint 22 rotating in its housing.
- piloting aid means are embedded in the drone, which are in this case fixed in the upper part of a part comprising the intermediate stop 35 and having for this purpose a mast 50: it this is, according to one possible configuration and as already mentioned, at least one camera 51 able to operate in combination with laser pointers 52, which are for example managed by the system to intersect in front of the contact element 10 with a view to help the pilot to better aim, in flight, a surface patch, so as to allow a connection with the lightning path of a wind turbine blade.
- the piloting aid means could be replaced by the implementation of guidance by lidar.
- the signals and images they provide to the pilot located at the bottom of the wind turbine allow substantial assistance for piloting the drone, the pilot being able to optimally manage the approach of the target located on the object, after having chosen, depending on the nature of said target, one of the three contact elements described above.
- the examples of technologies given above are not exhaustive of the invention, which on the contrary encompasses multiple variants of shapes and structure, such as for example for the mechanism of connection between the contact element 10, 100 and the arm 40, or the design modes of the quilted conductive coating of the contact element 10, 100 as illustratively shown in the configurations described in more detail previously.
