Description

[Technical Field]

[0001] The present invention relates generally to the technical field of wind turbines, and more particularly to an ice fall protection system mounted on a wind turbine tower to protect at least one moving object collision prevention device and / or at least one moving object monitoring device on the wind turbine tower surface from falling ice, both of which are mounted on the wind turbine tower. The moving object can be an animal (flying or non-flying), a moving vehicle (flying or non-flying), etc. An example of a flying vehicle is an unmanned aerial vehicle (drone). [Background technology]

[0002] Today it is known to use moving object monitoring devices (eg, imaging cameras) mounted on the tower of a wind turbine and / or moving object collision avoidance devices (eg, speakers) on the surface of the tower of the wind turbine.

[0003] In case of adverse weather conditions such as snowfall or ice on the outer wall of the tower, ice that accumulates on the blades or spindle of the wind turbine or on the outer wall of the tower often falls onto the above-mentioned equipment attached to the tower, resulting in damage or even destruction of said equipment.

[0004] To protect the above-mentioned device from falling ice, a protection system is used, which includes a cover and a strap, and the cover is attached to the tower by fastening the strap to the tower. More specifically, the strap crosses the cover and the two ends of the arc-shaped portions of the connected strap, surrounding the outer periphery of the tower at the fastening height of the cover, thereby achieving fastening of the cover to the tower. The mounting height of the cover is greater than the mounting height of the above-mentioned device, and the cover is fastened on the same vertical line as the above-mentioned device. The cover has dimensions and a shape that cover the above-mentioned device and thus protect it from falling ice. According to one example, the cover has the shape of a roof that covers the above-mentioned device.

[0005] However, if the cover needs to be replaced, for example because it has been damaged or destroyed by falling ice, a person skilled in the art must climb to the height of the wind turbine tower on which the cover is attached, unclasp the straps to remove the cover, and then install a new cover by refastening it to the wind turbine tower with the straps.

[0006] Therefore, in the above-mentioned existing ice fall protection systems, the skilled worker has to work and stay at the height of the cover for a long time, which makes the work more tiring. Furthermore, the longer the skilled worker stays at the height of the cover, the greater the risk of a work accident.

[0007] Furthermore, it can be seen that existing protection systems are not fastened very tightly to the tower of the wind turbine, and therefore the system can move out of its position, especially if large chunks of ice fall or if ice accumulating on the tower slides, resulting in a person skilled in the art having to climb up to the height of the tower where the system is located in order to return the system to its position. Summary of the Invention [Problem to be solved by the invention]

[0008] It is an object of the present invention to advantageously address the disadvantages and shortcomings of existing systems. [Means for solving the problem]

[0009] The present invention discloses an ice fall protection system for at least one moving object monitoring device and / or at least one moving object collision prevention device mounted on the tower of a wind turbine, the ice fall protection system being adapted to be mounted on the tower of the wind turbine on the same perpendicular line as the at least one moving object monitoring device and / or at least one moving object collision prevention device and at a height higher than the mounting height of the at least one moving object monitoring device and / or at least one moving object collision prevention device, and comprising at least one cover adapted to cover the at least one moving object monitoring device and / or at least one moving object collision prevention device to protect them from falling ice.

[0010] The protection system of the present invention comprises: a mounting base for at least one cover on a tower surface of a wind turbine, the mounting base having a flat surface (A) in the shape of a quadrilateral and at least one pair of opposing walls each extending perpendicularly to the flat surface (A) along each of two opposing sides of the flat surface (A); the mounting base is adapted to be fastened to the tower of the wind turbine by at least one elongated fastening means having two ends and a length sufficient to encircle the outer periphery of the wind turbine tower at a fastening height of the mounting base while crossing the front part of the flat surface (A) from one wall of the mounting base to the other; and after the outer periphery of the wind turbine tower has been encircled, the two ends of the fastening means are adapted to be connected to each other to achieve fastening of the mounting base to the tower of the wind turbine; and the cover comprises an ice splash surface (B) having a quadrilateral shape and at least one pair of opposing sloping walls, each of the opposing sloping walls extending perpendicular to the splash surface (B) along each of two opposing sides of the splash surface (B), each of the two opposing sloping walls subtending the same angle (θ) along each of the two opposing sides of the splash surface (B); The two opposing inclined walls of the cover and the two opposing walls of the mounting base are detachably connected to each other so that the cover can be detachably attached to the tower of the wind turbine, and the splash surface (B) of the cover is adapted to have a certain inclination with respect to the surface of the tower of the wind turbine so that when ice falls onto the splash surface (B), the ice hitting the splash surface (B) is splashed and scattered by the inclined splash surface (B) away from the moving object monitoring device and / or the moving object collision prevention device covered by the cover. It is characterized by:

[0011] An important advantage of the above-described protective system of the present invention, in which the mounting base remains fastened to the tower, is that replacing the cover requires less time than replacing a cover in existing protective systems, since the fastening means remain fastened to the mounting base on the tower surface, eliminating the need to unfasten and refasten the fastening means. With the protective system of the present invention, a skilled worker only needs to disconnect the destroyed cover from the mounting base and then connect a new cover to the mounting base, which can be easily accomplished because the cover is removably connected to the mounting base. Therefore, the time a skilled worker spends at the height of installing the cover in the protective system of the present invention is shorter than that spent in existing protective systems, making the work less tiring and reducing the risk of work accidents compared to the risks present in existing protective systems.

[0012] Furthermore, due to the fact that in the protective system of the present invention, a mounting base with a flat surface that is traversed by the fastening means is fastened to the tower, and the cover itself is not fastened to the tower as in the case of the existing systems in which the cover itself is traversed by the fastening means, the attachment of the protective system of the present invention to the tower is more rigid than that of the existing systems. This is because the mounting base of the protective system of the present invention has a flat surface and does not protrude significantly from the tower, in contrast to the uneven and bulky covers (e.g., roof-shaped covers) of the existing protective systems. Therefore, the protective system of the present invention is very resistant to being dislodged from its position even if a large block of ice falls on it, and therefore a person skilled in the art does not need to climb to the height of the tower to which the protective system is attached in order to return the protective system to said position.

[0013] According to one embodiment of the present invention, each of the two opposing walls of the mounting base is provided with at least one hole, so that at least one elongated fastening means passes through the at least one hole in each of the two opposing walls while crossing the front part of the flat surface (A) of the mounting base from one wall to the other of the mounting base, so that after two ends of the at least one fastening means are connected, the mounting base is mounted on the tower in such a way that the entire rear part of the flat surface (A) of the mounting base is in contact with the wall of the tower; Each of the two opposing inclined wall portions of the cover has at least one hole located at each of the two opposing inclined wall portions such that the hole overlaps with the corresponding hole in each of the two opposing wall portions of the mounting base after the two opposing inclined wall portions of the cover are connected to the two opposing wall portions of the mounting base, whereby the at least one fastening means passes through the at least one hole in each of the two opposing inclined wall portions of the cover and the at least one hole in each of the two opposing wall portions of the mounting base simultaneously while crossing the front portion of the flat surface (A) of the mounting base from one wall portion to the other wall portion of the mounting base.

[0014] According to another embodiment of the present invention, the mounting base comprises at least one fastening means guide fixed to at least one area of ​​the front surface of the face (A) of the mounting base, which is an area through which at least one fastening means passes while crossing the front surface of the face (A) from one wall of the mounting base to the other wall, and the at least one guide comprises two walls which face each other on the front surface of the face (A) and are fixed apart from each other so that at least one fastening means can pass between the walls of the guide.

[0015] According to yet another embodiment of the present invention, at least one of the two opposing walls of the mounting base comprises at least one opening adapted to receive and secure at least one removable bracket to said at least one of the two opposing walls, and the at least one removable bracket comprises at least one magnet on a surface thereof, such that an attractive force exerted by the magnet against the wall of the wind turbine tower helps to hold the mounting base on the tower when the mounting base is attached to the tower, and the at least one removable bracket is adapted to be inserted into said at least one opening only when the mounting base is attached to the tower and to be withdrawn from said at least one opening after the mounting base has been attached to the tower.

[0016] According to another embodiment of the invention, the at least one fastening means is a wire rope.

[0017] According to another embodiment of the invention, at least one area of ​​the rear side of the flat surface (A) of the mounting base is made of a slip-resistant material.

[0018] According to yet another embodiment of the present invention, the ice fall protection system comprises ice breaking means removably attached to the splash surface (B).

[0019] According to another embodiment of the present invention, the ice breaking means is removably attached to the splashing surface (B) and comprises two triangular faces (C, D) arranged relative to each other so that they abut at their common line (Z) and converge above at their common convergence point (S), so that the two triangular faces (C, D) form a pyramidal structure with the splashing surface (B) having the common convergence point (S) as its vertex, so that when ice falls onto the splashing surface (B), the ice hitting the pyramidal structure is crushed and the crushed ice is splashed and scattered by the two triangular faces (C, D) away from the moving object monitoring device and / or moving object collision prevention device and to both sides of the moving object monitoring device and / or moving object collision prevention device.

[0020] According to another embodiment of the invention, the two triangular faces are flat.

[0021] Furthermore, according to another embodiment of the present invention, the two triangular faces are zigzag shaped with sharp edges that will strike when the ice breaks against the pyramidal structure.

[0022] The invention also proposes a wind turbine equipped with at least one ice fall protection system as described in the above embodiments.

[0023] The present invention will now be more fully disclosed to those skilled in the art by reference to the accompanying drawings, which show, by way of example and not limitation, a preferred embodiment of an ice fall protection system, also referred to as "ice protection."

DETAILED DESCRIPTION OF THE INVENTION

[0025] Preferred exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.

[0026] As shown in Figures 1, 3 and 4, the ice fall protection system for at least one moving object monitoring device and / or at least one moving object collision prevention device on the tower surface of a wind turbine comprises a cover (10) adapted to be mounted on the tower of the wind turbine at a height higher than the mounting height of the above-mentioned devices and on the same vertical line as the above-mentioned devices. Furthermore, the cover (10) is adapted to sufficiently cover the above-mentioned devices to protect them from falling ice. In particular, the dimensions of the cover depend on the dimensions of the above-mentioned devices and are such that sufficient coverage of the above-mentioned devices is achieved to prevent ice from falling onto the above-mentioned devices.

[0027] In one example not shown in the drawings, when more than one of the above-mentioned devices is mounted on the tower, more than one cover is mounted above the above-mentioned devices at the same perpendicular line, and these covers are sized to fully cover the above-mentioned devices. The more than one cover may be mounted at the same height around the periphery of the tower, or at different heights on the tower depending on where the above-mentioned devices they are to cover are mounted.

[0028] Furthermore, as shown in Figures 1, 2 and 4, the above-mentioned protection system comprises a mounting base (1) for the cover on the tower surface of the wind turbine and at least one fastening means (15, 15') for the mounting base (1) on the tower surface of the wind turbine.

[0029] As shown in Figure 2, the mounting base (1) comprises a flat surface (A) having a quadrilateral shape and a pair of opposing walls (2, 2') each extending perpendicular to the flat surface (A) along each of two opposing sides of the flat surface (A). Although the flat surface (A) in Figures 1, 2 and 4 is rectangular in shape, it may have another shape, for example a square shape, according to other examples not shown in the drawings.

[0030] As shown in FIG. 4, the mounting base (1) is adapted to be attached to the tower of a wind turbine by fastening means, specifically, by two ropes (15, 15′), each having two ends and a length sufficient to encircle the outer periphery of the tower of the wind turbine at the height where the system is to be installed. After each of the two ropes (15, 15′) encircles the outer periphery of the tower, the two ends of each rope (15, 15′) are connected to each other to complete the attachment of the mounting base (1) to the tower. According to one example not shown in the drawings, the two ends of each rope (15, 15′) are connected to each other by fastening one end to the other end, or by a tensioner. According to another example not shown in the drawings, when the two ends of each rope (15, 15′) are connected using a tensioner, at least one spacer is placed on the outer wall of the tower along the periphery, so that each rope (15, 15′) encircling the outer periphery of the tower passes through the spacer. The spacers are adapted to keep each rope (15, 15') passing through them away from the outer wall of the tower so that the tensioner does not come into contact with the tower.

[0031] Furthermore, as shown in Figures 2 and 4, each of the two opposing walls (2, 2') of the mounting base (1) has two holes, so that the rope (15) passes through each of the two opposing holes (16, 16") and the rope (15') passes through each of the two opposing holes (16', 16'") while crossing the front portion of the flat surface (A) of the mounting base (1) from one wall (2) to the other wall (2') of the mounting base (1), and after the two ends of each rope (15, 15') are connected, the mounting base (1) is mounted to the tower with the entire back portion of the flat surface (A) of the mounting base (1) in contact with the wall of the tower. According to one embodiment, at least a certain area (preferably the entire area) of the back surface of the flat surface (A) of the mounting base (1) is made of a slip-resistant material (e.g., rubber) with a high slip coefficient, thereby making the mounting base (1) less likely to move, for example, if a large block of ice falls on it.

[0032] According to another example shown in Figures 2 and 4, the mounting base (1) comprises four rope guides (19) fixed to four different areas of the front surface of the flat surface (A) of the mounting base (1), in which the ropes (15, 15') pass across the front surface of the surface (A) of the mounting base (1) from one wall (2) to the other wall (2') of the mounting base (1). 2 and 4, each rope passes through two guides (19), each of the four guides (19) having two walls facing each other at the front of the surface (A) and fixed (for example, by means of threaded fastenings such as screws) at a distance from each other (the distance between the two walls must correspond to the diameter of the rope) so that the rope (15, 15') can pass through these walls and each guide (19) guides the rope (15, 15') across the front of the flat surface (A) of the mounting base (1) from one wall (2) to the other wall (2') of the mounting base (1). According to another example not shown in the drawings, each rope could pass through only one guide (19) or more than two guides (19).

[0033] According to another example shown in Figure 2, each of the two opposing walls (2, 2') of the mounting base (1) has two openings (6) adapted to receive and secure two removable brackets (7) to each of the two opposing walls (2, 2'). According to an example not shown in the drawings, the securing can be achieved by screw fasteners. Each of the four removable brackets (7) in Figure 2 has a magnet in the center of its surface, so that the attractive force exerted by the magnet against the tower wall helps the mounting base (1) to be attached to the tower when the mounting base (1) is attached to the tower. The four removable brackets (7) are adapted to be inserted into the four openings (6) only when the mounting base (1) is attached to the tower of the wind turbine and to be withdrawn from the four openings (6) after the mounting base (1) has been attached to the tower, because after completion of said attachment the mounting base (1) is fastened and held to the tower surface by ropes (15, 15'). According to another example not shown in the drawings, each of the two opposite walls (2, 2') of the mounting base (1) comprises one or more openings (6) adapted to receive and fix one or more removable brackets (7) to each of the two opposite walls (2, 2').

[0034] According to one embodiment, the ropes (15, 15') are wire ropes. The advantage of wire ropes over other fastening means is that they provide a more solid and durable fastening of the mounting base (1) to the tower. According to another embodiment, instead of ropes, straps or chains or adjustable hoops or similar elongated fastening means could be used to attach the mounting base (1) to the wind turbine tower. Also, according to another example not shown in the drawings, only one rope could be used to attach the mounting base (1), although it is clear that using two or more ropes increases the stability of attaching the mounting base (1) to the wind turbine tower.

[0035] As shown in Figures 1 and 3, the cover (10) includes a flat, quadrilateral-shaped ice splash surface (B) and at least one pair of opposing, sloping walls (12, 12'), each of which extends perpendicular to the splash surface (B) along two opposing sides of the splash surface (B), and each of the opposing, sloping walls (12, 12') exhibits the same slope (θ) along each of the two opposing sides of the splash surface (B). While the splash surface (B) in Figures 1 and 3 is rectangular, it may have another shape, such as a square, according to other examples not shown in the drawings. The shape and perimeter of the splash surface (B) correspond to the shape and perimeter of the flat surface (A) of the mounting base (1).

[0036] As shown in Figures 1, 2, 3, 4 and 5, the two opposing inclined walls (12, 12') of the cover (10) and the two opposing walls (2, 2') of the mounting base (1) are detachably connected to each other so that the cover (10) can be detachably attached to the tower of the wind turbine, and the splash surface (B) of the cover (10) is adapted to be inclined with respect to the surface of the tower of the wind turbine so that when ice falls onto the splash surface (B), the ice hitting the splash surface (B) is bounced and scattered by the inclined splash surface (B) away from the moving object monitoring device and / or the moving object collision prevention device covered by the cover (10).

[0037] More specifically, according to the examples of Figures 1, 2, 3, 4 and 5, the two opposing inclined walls (12, 12') of the cover (10) are provided with five holes, and the two opposing walls (2, 2') of the mounting base (1) are each provided with five holes that are appropriately positioned so that the holes in the mounting base (1) overlap with the holes in the cover (10) after the mounting base (1) is connected to the cover (10). After the mounting base (1) is connected to the cover (10) as described above, the screw fastening parts are simultaneously passed through the five holes of the mounting base (1) and the five holes of the cover (10) that overlap them, thereby achieving a detachable connection by screwing the two opposing inclined walls (12, 12') of the cover (10) to the two opposing walls (2, 2') of the mounting base (1), and essentially a detachable connection of the mounting base (1) to the cover (10).

[0038] Furthermore, according to the example of Figures 1, 2, 3, 4 and 5, each of the two opposing inclined walls (12, 12') of the cover (10) has two holes. Specifically, as shown in Figure 3, the inclined wall (12) has two holes (17, 17'), and the inclined wall (12') has two holes (17", 17'") dimensioned to allow the ropes (15, 15') to pass through. The holes (17, 17', 17'', 17''') are provided at each of the two opposing walls (12, 12') of the cover (10) so as to overlap with the corresponding holes (16, 16', 16'', 16''') of the two opposing walls (2, 2') of the mounting base (1) after the two opposing inclined walls (12, 12') of the cover (10) are connected to the two opposing walls (2, 2') of the mounting base (1); As a result, the ropes (15, 15') cross the front portion of the flat surface (A) of the mounting base (1) from one wall portion (2) to the other wall portion (2') of the mounting base (1), and simultaneously pass through the holes (17, 17', 17'', 17''') in each of the two opposing inclined walls (12, 12') of the cover (10) and the holes (16, 16', 16'', 16''') in each of the two opposing walls (2, 2') of the mounting base (1).

[0039] According to the example of Figures 6a and 6b, the ice fall protection system comprises ice breaking means (13) connected to the splash surface (B) by welding. In an alternative embodiment not shown in the drawings, said connection could be achieved by screwing the ice breaking means (13) to the splash surface (B).

[0040] In the example of Fig. 6a, the ice breaking means (13) is connected to the splash surface (B) of the cover (10) and comprises two flat triangular faces (C, D) arranged relative to each other such that they abut at their common side (Z) and converge above at their common convergence point (S), the two triangular faces (C, D) forming a pyramidal structure with the splash surface (B) of the cover (10) having the common convergence point (S) as its apex. When ice falls onto the splash surface (B), it hits the pyramidal structure and is consequently shattered, and the shattered ice is repelled and scattered by the two triangular faces away from the moving object monitoring device and / or moving object collision prevention device covered by the cover (10) and on both sides of the moving object monitoring device and / or moving object collision prevention device.

[0041] In the example of Fig. 6b, the two triangular faces (C, D) of the ice-breaking means (13) are not flat like those in Fig. 6a, but have a zigzag shape that forms sharp edges (77) over the entire area of ​​the pyramidal structure against which ice striking the pyramidal structure is broken. This is the only difference between the protection systems of Examples 6a and 6b. The advantage of the zigzag triangular faces is that ice breaking is achieved over the entire area of ​​the pyramidal structure, and not only in the area of ​​the common side (Z) of the two flat triangular faces, as in the example of Fig. 6a. Therefore, the zigzag triangular faces are more effective at breaking up ice falling on them.

[0042] Figures 7a and 7b show an exemplary embodiment of a mounting system (70) for three moving object monitoring devices (a dome camera (71), a thermal imaging camera (72), and a dome security camera (73)) and one moving object collision prevention device (a speaker (74)), and the protection system of Figures 6a and 6b mounted above the system (70) to protect the devices from falling ice.

[0043] In the example of Figures 7a and 7b, there is a gap (H) between the mounting system (70) and the ice fall protection system. According to another example not shown in the drawings, the protection system is mounted directly above the mounting system (70), in which case there is zero gap (H) between the mounting system (70) and the ice fall protection system.

[0044] According to another example not shown in the drawings, the mounting system (70) may include one, two, or three of the above four devices of Figures 7a and 7b, or any combination of more than four devices. Also, according to other examples not shown in the drawings, the ice fall protection system covers a mounting system of a different configuration than that of the mounting system (70) of Figures 7a and 7b, and a moving object monitoring device and / or moving object collision prevention device on a different tower surface than the moving object monitoring device and / or moving object collision prevention device of the example of Figures 7a and 7b.

[0045] The wind turbine may be equipped with at least one ice fall protection system as described in the above examples of the detailed description of the preferred embodiments and shown in the drawings.

[0046] It should be noted that the above description of the invention has been made with reference to preferred embodiments, but is not limited thereto, and therefore any changes or modifications in shape, form, size, materials used and construction techniques are deemed to be within the spirit and scope of the invention.
