Description

Field of the Invention

[0001] The present invention relates to the field of protecting the fragile wingtips of wind turbine blades during transportation, storage and other handling of the wind turbine blades.

[0002] The fragile wingtips are protected by providing protective covers which are mounted over the wingtips and secured to the wingtips by straps. Background of the Invention

[0004] Protection and visual indication of the wingtips of wind turbine blades are very important to ensure that these fragile wingtips are not damaged during transportation and / or storage.

[0005] Existing solutions are typically made of foam with cutouts designed for specific wingtips and secured to the wingtips with straps. However, because the cutouts are designed for specific wingtips, existing solutions are not securely fixed to wingtips of different shapes and sizes and often fall off during transportation or storage.

[0006] In other cases, the straps in existing solutions are over-tightened, potentially damaging the edges of the delicate wingtips.

[0007] Due to the poor adaptability of existing solutions, transport personnel need to use tape to fix the protective cover to the fragile wingtips, but the strong adhesive may damage the paint surface of the fragile wingtips.

[0008] Purpose of the Invention

[0009] One object of the present invention is to realize a protective cover that provides good protection for the fragile wing tips of elongated elements such as wind turbine blades.

[0010] Another object is to achieve a protective cover that is properly fixed to the wing tip and that does not damage the wing tip during the process of fixing the protective cover to the wing tip.

[0011] Another object is to achieve a high visibility protective cover so that the fragile wing tips cannot be accidentally touched during transport or storage of the elongated unit. Summary of the Invention

[0012] One object of the present invention is achieved by a protective cover for a fragile wingtip of a slender unit, the protective cover comprising an inner shell made of an elastic material and an outer shell made of a rigid or semi-rigid material, the protective cover being designed to be installed so that the inner shell surrounds and contacts the wingtip, the outer shell forming the outer upper and lower surfaces of the protective cover, the protective cover comprising at least two through-holes or slits extending from the upper surface to the lower surface of the outer shell, the through-holes or slits being designed to accommodate straps so that the protective cover can be detachably fixed to the wingtip by applying force to the outer shell and utilizing the friction between the wingtip and the inner shell.

[0013] One advantageous effect of the double-shell design (i.e., the inner shell is made of an elastic material and the outer shell is made of a rigid or semi-rigid material) is that the pressure of the fixing straps is evenly distributed through the outer shell, acting on the flat surface of the vulnerable wingtip rather than directly on one or more edges of the vulnerable wingtip. Thus, the protective cover can be properly fixed to the wingtip without the risk of over-tightening, thereby ensuring that the protective cover will not fall off, for example, due to vibrations and / or wind and air resistance during transportation.

[0014] Another advantage of the inner shell being made of an elastic material is that the inner shell fits tightly to the wingtip due to friction.

[0015] In another embodiment of the protective shield, the inner shell and the outer shell of the protective shield are made of a single material, which can be an elastic material, such as polyurethane (PUR). In one aspect of this embodiment, the material can adopt a hard material internal reinforcement structure extending longitudinally of the protective shield and / or across the width of the protective shield. The internal reinforcement structure can also be a mesh or cross pattern to provide additional reinforcement. The hard material of the internal reinforcement structure may include plastic, metal, wood or a composite material. The internal reinforcement structure can be placed in specific parts of the protective shield (such as the area where the pressure of the fixed strap is located) or placed throughout the protective shield to achieve evenly distributed reinforcement.

[0016] In another embodiment of the protective cover, the protective cover is designed to hold a visual indicator.

[0017] One advantage of providing a visual indicator is that fragile wingtips may be easily detected, for example during transport where the wingtip may protrude beyond a portion of the vehicle or during storage where a small and / or thin wingtip may not be easily detected.

[0018] In another embodiment of the protective cover, the protective cover comprises fixing means for fixing one or more second visual indicators in a vertical direction above or below the wing tip.

[0019] The fixing means may be a through hole or a slit provided on the protective cover, or the fixing means may be a ring or an eyelet provided on the housing.

[0020] One advantage of providing one or more second visual indicators in a vertical direction above or below the wingtip is that if the wingtip is approximately below or above the general field of view during transportation or storage, the vertically arranged second visual indicator can indicate that the wingtip is below or above the second visual indicator, respectively.

[0021] In one embodiment, the second visual indicator can be a line marking strip, band, tape, or rope. The second visual indicator can be freely suspended or attached to a portion of the transport vehicle, a cradle, a shroud of another blade, or any other fixture near the shroud. The second visual indicator can also be positioned horizontally, such as between two adjacent wingtips provided with shrouds.

[0022] In another embodiment of the protective cover, the visual indicator comprises a reflective material.

[0023] One advantage of the visual indicator or secondary visual indicator comprising a retroreflective material is that it is easily detectable under all lighting conditions of the day, whether dawn, daytime, sunset, evening and / or nighttime.

[0024] In another embodiment of the protective cover, the visual indicator comprises a fluorescent material.

[0025] The fluorescent material may be a single color or a mixture of different colors, for example in a stripe or ring pattern.

[0026] One advantage of the visual indicator or second visual indicator comprising a fluorescent material is that its striking color is highly visible, alerting and increasing awareness of persons surrounding the visual indicator and the object covered by the visual indicator.

[0027] In another embodiment of the protective cover, the visual indicator comprises one or more light sources.

[0028] The light source may be a continuous light of one or more luminescent colors, or the light source may be a rotating and / or flashing light of one or more luminescent colors. The light source may be attached to the protective cover via fixing means such as bolts and nuts by clamping or gluing to the protective cover.

[0029] An advantage of the visual indicator comprising one or more light sources is that visibility of the wingtip is further enhanced, thereby improving overall safety during transport and / or storage.

[0030] In another embodiment of the protective cover, the protective cover includes an upper shell part and a lower shell part.

[0031] An advantage of the protective cover comprising an upper shell member and a lower shell member is that a single protective cover is suitable for covering and protecting a variety of wingtip sizes and shapes.

[0032] Another advantage is that if the upper or lower shell part is damaged during operation or degraded due to wear, the upper or lower shell part of the protective cover can be replaced individually without having to replace the entire protective cover.

[0033] In another embodiment of the protective cover, the inner shell is made of polyurethane (PUR). The inner shell material may include hollow sections designed to make the inner shell more deformable, thereby ensuring that the inner shell can conform to the shape of the fragile wingtip, thereby increasing the fastening force of the protective cover to the fragile wingtip.

[0034] In another embodiment of the protective cover, an end stop is provided on the protective cover, configured to protect the longitudinal end of the wing tip.

[0035] In another embodiment of the protective cover, the end stop is provided with a visual indicator and the embodiments of the visual indicator disclosed above.

[0036] In one embodiment of the protective cover, the protective cover is designed to cover one or more trailing edges and / or leading edges or wingtips of the elongated unit, the protective cover is made of an elastic material and includes an inner surface, an outer upper surface and an outer lower surface, the inner surface is designed to be mounted in contact with the upper surface and the lower surface, the outer upper surface and the outer lower surface face outward and away from the inner surface, wherein the protective cover is designed to extend beyond the edge or wingtip of the elongated unit, wherein the protective cover includes at least one through-hole or slit extending from the outer upper surface to the outer lower surface, and the through-holes or slits are designed to accommodate straps so as to detachably fix the protective cover to the elongated unit by applying force to the outer upper surface and / or the outer lower surface and utilizing the friction between the inner surface and the upper surface and / or the lower surface.

[0037] In this embodiment of the protective cover, the protective cover is adapted to cover one or more longitudinal sides and / or edges of the elongated element.The longitudinal sides and / or edges may be the leading edge and / or the trailing edge of the elongated element, such as a wind turbine blade.

[0038] In this embodiment, the protective cover is configured with an upper shell member and a lower shell member, each of which is configured to cover two opposing sides or edges of the elongated element. Thus, the upper shell member and the lower shell member are configured to cover the edge and conform to the shape of the edge. In this manner, the upper shell member and the lower shell member are configured to converge and connect near the edge of the elongated element, thereby covering and protecting the edge.

[0039] An advantage of the protective cover comprising an upper shell part and a lower shell part is that a single protective cover can be adapted to cover and protect a variety of wing tips of different sizes and shapes. Similarly, two shell parts of different sizes and shapes can also be fastened together and fixed to the sides or edges of the elongated unit.

[0040] Another advantage is that if the upper or lower shell part is damaged during operation or degraded due to wear, the upper or lower shell part of the protective cover can be replaced individually without having to replace the entire protective cover.

[0041] In another embodiment of the protective cover, the protective cover includes an inner shell made of an elastic material and an outer shell made of a rigid or semi-rigid material, wherein the outer shell forms an outer upper surface and an outer lower surface, and the straps detachably secure the protective cover to the elongated unit by applying force to the outer shell and utilizing friction between the edge or wingtip of the elongated unit and the inner shell.

[0042] One effect of providing an outer shell made of a rigid or semi-rigid material is that when one or more straps apply pressure to the outer shell, the pressure is evenly distributed to all parts of the inner shell, including parts not directly covered by the straps, thereby enhancing the securing effect of the protective cover to the edges and / or wingtips of the slender unit.

[0043] In another embodiment of the protective cover, the elastic material is reinforced by an internal reinforcement structure. The internal reinforcement structure includes a rigid or semi-rigid material for increasing the durability and strength of the elastic material.

[0044] One effect of the elastic material being equipped with internal reinforcements is that the protective cover has greater durability and can be more securely fixed to the elongated element by distributing the clamping force of the straps throughout the elastic material. This distribution of the clamping force throughout the elastic material further prevents damage to the elongated element caused by overtightening of the straps or continuous clamping pressure.

[0045] In another embodiment of the protective cover, the inner reinforcement structure is plastic, metal, wood and / or a composite material.

[0046] In another embodiment of the protective cover, the internal reinforcement structure is arranged parallel and / or perpendicular to the longitudinal direction of the elongated elements.

[0047] In another embodiment of the protective cover, the internal reinforcement structure is arranged in a mesh pattern.

[0048] In another embodiment of the protective cover, the protective cover includes one or more visual indicators.

[0049] In another embodiment of the protective cover, the one or more visual indicators include reflective material, fluorescent material, and / or one or more light sources.

[0050] An advantage of visual indicators comprising reflective or fluorescent materials is that they are easily detectable under all lighting conditions of the day, whether at dawn, daytime, sunset, evening or nighttime.

[0051] The light source may be a continuous light of one or more luminous colors, or a rotating and / or flashing light of one or more luminous colors. The light source may be attached to the protective cover via fixing means such as bolts and nuts by clamping or gluing to the protective cover.

[0052] An advantage of the visual indicator comprising one or more light sources is that visibility of the elongated unit is further enhanced, thereby improving overall safety during transport and storage.

[0053] In another embodiment where the protective cover covers the longitudinal sides and / or edges of the elongated unit, the protective cover is provided with one or more visual indicators and embodiments of visual indicators disclosed herein above.

[0054] In another embodiment of the protective cover, the protective cover includes an upper shell component and a lower shell component, wherein the upper shell component and the lower shell component are configured to be disposed opposite each other with the elongated element positioned between the two components.

[0055] In this embodiment, the upper and lower shell members are connected along the edge of the elongated unit when covering both sides of the respective elongated unit, or there may be a gap between the two members when the protective cover is provided around the edge of the elongated unit.

[0056] In another embodiment of the protective cover, the elastic material is polyurethane (PUR).

[0057] One effect of the polyurethane elastic material is that it provides strong protection for the covered object. By providing air pillows or cushions within the elastic material, the cover can further resist impacts that would otherwise be transmitted to the protected object. The air pillows or cushions within the elastic material can also prevent damage to the elongated elements due to over-tightening of the straps. BRIEF DESCRIPTION OF THE DRAWINGS

[0078] DETAILED DESCRIPTION

[0079] Figure 1 shows an embodiment of securing the protective cover 10 to the fragile wingtip 1 using two straps 50. To secure the protective cover 10 to the fragile wingtip 1, one or more straps are inserted into through-holes 40 provided in the protective cover 10. Multiple through-holes 40 are provided in the protective cover 10 across its width, perpendicular to the longitudinal extension of the fragile wingtip 1. The provision of multiple through-holes 40 allows the protective cover 10 to accommodate a wide range of wingtip sizes. Another purpose of the multiple through-holes 40 is to tighten the straps, securing the protective cover 10 securely to the fragile wingtip 1 while ensuring contact between the straps 50 and the fragile wingtip 1 and preventing damage from pressure from vibration or friction from the straps 50. The protective cover 10 includes an inner shell 20 made of an elastic material, which contacts the fragile wingtip 1. The elastic material of the inner shell 20 may deform when pressed against the fragile wingtip 1, thereby enhancing the fastening force of the protective cover 10 on the fragile wingtip 1. The protective cover 10 also includes an outer shell 30, which is made of a rigid or semi-rigid material and forms the upper and lower surfaces of the protective cover 10. The rigid outer shell 30 ensures that the pressure of the strap 50 is evenly distributed to the inner shell 20 and on the fragile wingtip 1.

[0080] Figure 1b A rear view of one embodiment of a protective cover 10 secured to a fragile wingtip 1 is shown. The protective cover includes an upper shell component 12 and a lower shell component 14, which enclose the fragile wingtip 1. Both the upper shell component 12 and the lower shell component 14 have an inner shell 20 facing the fragile wingtip 1 and an outer shell 30 facing outward. The protective cover 10 also has a plurality of protrusions 34 configured to protect the fragile wingtip 1 from impact. These protrusions 34 can also be configured to attach reflective markings, fluorescent markings, and / or light sources to enhance the visibility of the protective cover during transport or storage of the fragile wingtip. These protrusions 34 can also be coated with a reflective or fluorescent coating. The protective cover 10 also includes an end stop 32 disposed at an end of the protective cover 10, where the end of the protective cover 10 extends beyond the outermost point of the fragile wingtip 1 or just outside the longitudinally extending end of the fragile wingtip 1. The end stop 32 is configured to protect the fragile wingtip 1 from impact and provide a visual indicator of the fragile wingtip through the use of reflective markings, fluorescent markings, and / or light sources. The end stop 32 may also be coated with a reflective coating or a fluorescent coating.

[0081] Figure 1cA top view shows an embodiment of attaching the protective cover 10 to the fragile wingtip 1 using straps 50 inserted through through-holes 40. Depending on the shape and size of the fragile wingtip 1, the straps 50 are inserted through different through-holes 40 to ensure secure and protective positioning around the fragile wingtip 1. Because two straps 50 are positioned around the protective cover, perpendicular to the longitudinal extension of the fragile wingtip and spaced apart, the elastic material of the inner shell 20, located beneath the straps, conforms to both the leading and trailing edges of the fragile wingtip, thereby preventing the protective cover 10 from falling due to vibration of the fragile wingtip 1 or wind or air resistance.

[0082] Figure 2 One embodiment of an end stop 32 is shown. In this embodiment, the end stop 32 comprises an octagonal plate, but it may also take the shape of a diamond, square, pentagon, hexagon, circle, triangle, cross, or any combination thereof. The end stop 32 also includes a bracket for attaching the end stop 32 to the protective cover 10. The end stop 32 may also be fully integrated with the protective cover 10 by being integrally molded with the protective cover 10, or permanently secured to the protective cover 10 by bonding or welding the materials together.

[0083] Figure 3a and 3b Another embodiment is shown in which the protective cover 10 is compactly packed together when not attached to the fragile wing tip. This embodiment also shows how the bracket of the end stop 32 is attached to the protective cover 10 by the fixing means 33.

[0084] Figure 4 The shell part of the protective cover 10 is shown as an example Figure 1b An embodiment of an upper or lower shell member is shown. The shell member includes an inner shell 20 facing the fragile wingtip, an outer shell 30 facing outward, and a plurality of through holes 40. The through holes 40 are designed to receive straps (not shown) to detachably secure the two shell members of the protective cover 10 to the fragile wingtip.

[0085] Figure 5 Another embodiment of securing the protective cover 10 to the fragile wingtip 1 using a strap 50 is shown. A through-hole 40 provided in the protective cover accommodates the strap 50. By spacing the through-hole 40 a certain distance from the edge of the fragile wingtip 1, the strap 50 is prevented from twisting excessively during the securing process and damaging the edge of the wingtip. When the strap 50 is secured around the protective cover 10, the pressure of the secured strap is transferred to the rigid or semi-rigid outer shell 30. The pressure from the outer shell 30 is applied to the inner shell 20. Leveraging the elastic material of the inner shell, the friction between the inner shell and the wingtip secures the protective cover 10 to the wingtip 1.

[0086] Figure 6aAn embodiment of a paddle-shaped protective cover 10 disposed above and below a fragile wingtip 1 is shown. The protective cover 10 includes an inner shell 20 that contacts the fragile wingtip 1, the inner shell 20 being made of an elastic material, and an outer shell 30 of a rigid or semi-rigid material, the outer shell 30 forming the upper and lower surfaces of the protective cover 10. The protective cover 10 also includes a plurality of slits 42 extending from the upper surface to the lower surface of the outer shell 30. The slits 42 are designed to accommodate straps (not shown) so that the two components of the protective cover 10 can be removably secured to the fragile wingtip 1 by applying force to the outer shell 30, utilizing friction between the wingtip and the inner shell 20. The protective cover 10 also includes end stops 32, which include the inner shell 20 and the outer shell 30. The end stops 32 are designed to secure one or more visual indicators.

[0087] Figure 6b Another embodiment of a paddle-shaped protective cover 10 is shown. The protective cover 10 comprises an upper shell component 12 and a lower shell component 14, wherein the two shell components surround the fragile wing tip 1. The protective cover 10 is also provided with a plurality of protrusions 34, which are configured to protect the fragile wing tip 1 from impact.

[0088] Figure 7 One embodiment of the upper shell member 12 of the protective cover 10 is shown. The upper shell member 12 includes a plurality of slits 42 designed to accommodate straps (not shown) and two protrusions 34 along the inner edge of a portion of the outer shell 30. The protrusions can be positioned below the area covered by one or more straps. When the straps secure the protective cover 10 to the wingtip 1, the protrusions 34 lift the straps away from the outer shell 30, thereby increasing downward pressure across the outer shell 30 via the protrusions 34. As a result, the pressure of the secured straps is more evenly distributed across the entire area of ​​the outer shell 30, rather than just in the narrow area covered by the straps themselves.

[0089] Figure 8 Another embodiment is shown, in which a triangular protective cover 10 is positioned above and below a vulnerable wingtip 1. The protective cover 10 has a plurality of through-holes 40 designed to accommodate straps (not shown). The protective cover 10 also has a securing device 44 for vertically securing one or more secondary visual indicators above or below the wingtip 1. The protective cover 10 also has a slot 22 in the inner shell 20, which is configured to increase friction between the wingtip 1 and the inner shell 20 of the protective cover 10.

[0090] Figure 9a One embodiment of a protective cover 10 surrounding a fragile wingtip 1 is shown.

[0091] Figure 9b Another embodiment of the protective cover 10 is shown.

[0092] Figure 10aOne embodiment of a protective cover 10 surrounding a fragile wingtip 1 is shown. In this embodiment, the protective cover 10 is provided with end stops 32 and is secured to the wingtip by straps 50 .

[0093] Figure 10b Shown Figure 6a Another embodiment of the protective cover in this embodiment, the protective cover is configured as two parts, one part is used to protect the wing tip 1, and the other part protects the edge of the slender unit, and the two parts are connected together by one or more fixing devices 46.

[0094] Figure 11a Another embodiment of a protective cover 10 for protecting one or more vulnerable edges or wingtips of an elongated element 2 is shown. The protective cover 10 of this embodiment is made of an elastic material and includes an inner surface 60, as well as outer upper and lower surfaces 70 and 71. The inner surface 60 is designed to contact the upper and lower surfaces of the vulnerable edges or wingtips of the elongated element 2, with the outer upper and lower surfaces 70 and 71 facing outward and away from the inner surface. The protective cover is designed to extend beyond the edge or wingtips of the elongated element, forming a protective area around the edge or wingtips. The protective cover 10 is provided with at least one through-hole, wherein the hole is designed to receive a strap to apply force to the outer upper and / or lower surfaces 70 and 71, thereby removably securing the protective cover to the elongated element by utilizing friction between the inner surface 60 and the upper and / or lower surfaces. In this figure, another protective member 80 is provided on the edge of the elongated element opposite the edge covered by the protective cover 10. In this embodiment, the straps 50 are positioned perpendicular to the longitudinal extension of the elongated element. However, one or more second straps 51 may alternatively be positioned parallel to the longitudinal extension of the elongated element and proximate the edge or wingtip of the elongated element 2. In this manner, the second straps 51 can provide a clamping force along the vulnerable edge on the outer upper surface 70 and the outer lower surface 71, further ensuring that the inner surface 60 is securely fixed around the edge or wingtip of the elongated element 2 and remains stable. In this embodiment, the protective cover 10 is further provided with a plurality of protrusions 34 configured to protect the vulnerable wingtip 1 from impact. These protrusions 34 are also configured to hold reflective or fluorescent markings and / or a light source to enhance the visibility of the protective cover during transport and storage of the vulnerable wingtip. These protrusions 34 may also be coated with a reflective or fluorescent coating.

[0095] Figure 11bA cross-sectional view of a protective cover 10 for protecting the trailing edge 3 or wingtip of an elongated element 2 is shown. The protective cover 10 is configured such that its inner surface 60 contacts the upper surface 90 and lower surface 91 of the trailing edge 3 of the elongated element 2. The protective cover 10 is secured to the trailing edge 3 by a strap 50 extending around the cross-section of the protective cover 10 and the elongated element 2. In this figure, the leading edge 4 is also protected by another protective member 80, but this component is not essential for practicing the present invention. This other protective member 80 may include any of the features of the protective cover disclosed herein and other embodiments of the protective cover. The protective cover 10 is further secured to the trailing edge 3 by a second strap 51 extending parallel to the trailing edge 3. This second strap 51 provides a clamping force along the trailing edge 3 on the outer upper surface 70 and the outer lower surface 71, further ensuring that the inner surface 60 is securely fixed around the trailing edge 3 and remains stable.

[0096] Figure 11c Shown as Figure 11a and 11b Another embodiment of another protective member 80 described in the accompanying drawings may include any of the features of the protective cover and other embodiments of the protective cover disclosed herein. The protective member 80 includes a plurality of through-holes 40 or slits 42 designed to receive the straps 50 so that the protective member 80 can be clamped to the elongated element 2 and / or the leading edge 4 of the elongated element 2.
