[0034] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In the detailed description below, many specific details are set forth in order to provide a comprehensive understanding of the present application. However, it will be apparent to those skilled in the art that the present application can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present application by illustrating examples of the present application. In the accompanying drawings and the following description, at least some of the well-known structures and technologies are not shown in order to avoid unnecessary ambiguity in the present application; and, for clarity, the sizes of some structures may be exaggerated. In addition, the features, structures, or characteristics described below may be combined in any suitable manner in one or more embodiments.

[0035] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of the blade clamp and blade transportation system of this application. In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0036] In the wind turbine industry, the increasing size of blades and their extra-long overhangs present unprecedented transportation challenges. To address this challenge, innovative split-body transporter designs have emerged on the international market, designed to accommodate increasingly stringent regulations for extra-long overhangs. By eliminating the traditional intermediate deck beam, these innovative split-body transporters not only provide greater flexibility but also allow wind turbine blades to be secured directly to the required extra-long overhangs. This design significantly improves transportation efficiency while enhancing safety during transport.

[0037] During transport, the blade body needs to be clamped and locked using a blade clamp to secure the blade's relative position to the transport equipment and ensure safe transport. The blade clamp must be opened and set, the blade placed inside, and then locked. Once the blade is transported to the intended location, the blade clamp must be opened again to remove and install the blade. In other words, the blade clamp must be opened to allow for assembly and disassembly of the blade.

[0038] However, the blade clamps in the related art are difficult to assemble and disassemble the blades, and are prone to causing damage such as scratches on the surface of the blades, affecting the reliability of blade transportation.

[0039] like Figures 1 to 3 As shown, based on this, one embodiment of the present application provides a blade clamp 100, including a clamping component 10 and a driving component 20. The clamping component 10 includes a first clamping portion 11 and a second clamping portion 12 arranged opposite to each other. The first clamping portion 11 and the second clamping portion 12 are configured to jointly clamp and fix the blade. The first clamping portion 11 and the second clamping portion 12 are rotatably connected to each other at one end in the first direction X and are detachably connected at the other end. The driving component 20 is connected between the first clamping portion 11 and the second clamping portion 12. The driving component 20 drives the second clamping portion 12 to rotate relative to the first clamping portion 11, and the maximum angle of relative rotation is greater than or equal to 90°.

[0040] The blade generally includes a blade root, a blade tip and a blade body located between the blade root and the blade tip along its length direction. The blade clamp 100 can be used to clamp and fix the blade body of the blade.

[0041] The first clamping portion 11 and the second clamping portion 12 may enclose and form a cavity 13 with an open setting or a closed setting, which may match at least a portion of the profile of the blade body.

[0042] The first clamping portion 11 and the second clamping portion 12 can be rotatably connected at one end in the first direction X by a structure such as a rotating shaft. The other ends of the first clamping portion 11 and the second clamping portion 12 can be detachably connected by a structure such as a locking component. When it is necessary to place a blade between the first clamping portion 11 and the second clamping portion 12, the other ends of the first clamping portion 11 and the second clamping portion 12 can be disassembled first so that the two can be separated from each other. After the blade is placed between the first clamping portion 11 and the second clamping portion 12, the other ends of the first clamping portion 11 and the second clamping portion 12 can be connected and fixed to clamp and fix the blade.

[0043] The driving member 20 can be fixedly connected to the first clamping portion 11 and the second clamping portion 12, or can be detachably connected. The driving member 20 is configured to apply a thrust to at least one of the first clamping portion 11 and the second clamping portion 12, thereby causing one of the first clamping portion 11 and the second clamping portion 12 to rotate relative to the other.

[0044] When the first clamping portion 11 and the second clamping portion 12 are connected at one end of the detachable connection in the first direction X, the rotation angle between the first clamping portion 11 and the second clamping portion 12 is 0°. When the first clamping portion 11 and the second clamping portion 12 are detached at one end thereof, the maximum rotation angle between the two is greater than 90°, which can be any value between 90° and 180°, and can be 90° to 150°.

[0045] The blade clamp 100 provided by one embodiment of the present application has a first clamping part 11 and a second clamping part 12 that are rotatably connected to each other at one end in the first direction X and are detachably arranged at the other end, so that the first clamping part 11 and the second clamping part 12 can be opened and arranged. The driving component 20 is set and connected between the first clamping part 11 and the second clamping part 12. The driving component 20 drives the first clamping part 11 to rotate relative to the second clamping part 12 and makes the maximum rotation angle greater than or equal to 90°, so that the blade can be installed between the first clamping part 11 and the second clamping part 12 through the opening formed by the maximum angle after rotation, or separated from the first clamping part 11 and the second clamping part 12. The blade can maintain a sufficiently large safety distance from the first clamping part 11 and the second clamping part 12 during the disassembly process, reducing the difficulty of disassembly and assembly of the blade, effectively avoiding the risk of the blade being scratched and damaged during the disassembly process, and ensuring the reliability of blade transportation.

[0046] Alternatively, the drive component 20 may be a drive motor or the like, which may be connected to one of the first clamping portion 11 and the second clamping portion 12 via a base, and have an output shaft connected to the other of the first clamping portion 11 and the second clamping portion 12. The output shaft rotates to drive one of the first clamping portion 11 and the second clamping portion 12 to rotate relative to the other, thereby achieving the required angular drive of the first clamping portion 11 and the second clamping portion 12. Of course, this is an optional embodiment.

[0047] In some optional embodiments, the blade clamp 100 provided in one embodiment of the present application, the driving component 20 may also include a telescopic member 21 and a connecting rod assembly 22, the connecting rod assembly 22 is rotatably connected to the first clamping part 11 and the second clamping part 12 respectively, the telescopic member 21 is rotatably connected to the first clamping part 11 and the connecting rod assembly 22 respectively, and the telescopic member 21 drives the second clamping part 12 to rotate relative to the first clamping part 11 through the connecting rod assembly 22.

[0048] The linkage assembly 22 may include a plurality of connections forming a connection structure.

[0049] The telescopic member 21 includes but is not limited to a pneumatic cylinder, a hydraulic cylinder, an electric cylinder, and the like.

[0050] The blade clamp 100 provided in one embodiment of the present application, through the above-mentioned arrangement, can provide power through the telescopic part 21 of the driving component 20, and through the extension and contraction of the telescopic part 21, transmit the power to the second clamping part 12 through the connecting rod assembly 22, driving the second clamping part 12 to rotate clockwise or counterclockwise relative to the first clamping part 11, and can also meet the driving requirements of the second clamping part 12, so that the second clamping part 12 rotates relative to the first clamping part 11, thereby ensuring the clamping and release requirements of the blade.

[0051] Continue reading Figures 1 to 3 As shown, in some optional embodiments, a blade clamp 100 provided by an embodiment of the present application has a first rotation center aa between the first clamping part 11 and the second clamping part 12, a second rotation center bb between the first clamping part 11 and the connecting rod assembly 22, a third rotation center cc between the second clamping part 12 and the connecting rod assembly 22, a first connecting line MM between the first rotation center aa and the second rotation center bb and a second connecting line NN between the first rotation center aa and the third rotation center cc form an angle β; the driving component 20 drives the clamping component 10 to switch between a closed state and an open state, in the closed state, β < 180°; in the open state, β < 90.

[0052] The first rotation center aa can be understood as: the first clamping portion 11 and the second clamping portion 12 are connected by a first rotation shaft, and the axis of the first rotation shaft can be understood as the first rotation axis.

[0055] The first rotating axis, the second rotating axis and the third rotating axis are parallel to each other.

[0056] like Figure 2 As shown, in the closed state, the first clamping portion 11 and the second clamping portion 12 are connected to each other at one end thereof which can be detachably connected. The relative rotation angle between the first clamping portion 11 and the second clamping portion 12 is 0°.

[0057] like Figure 3As shown, in the open state, the first clamping part 11 and the second clamping part 12 are detachably connected at one end and detached from each other, and the first clamping part 11 rotates relative to the second clamping part 12, optionally to a maximum angle.

[0058] The blade clamp 100 provided in one embodiment of the present application meets the driving requirements for the relative rotation of the first clamping part 11 and the second clamping part 12 through the above-mentioned arrangement, which is conducive to the rotation of the second clamping part 12 relative to the first clamping part 11 and the maximum angle of relative rotation is greater than or equal to 90°, thereby reducing the difficulty of disassembly and assembly of the blade and the risk of damage by scratches. At the same time, by making β < 180°, the driving component 20 can be prevented from getting stuck when driving the first clamping part 11 and the second clamping part 12 to rotate relative to each other, thereby ensuring the smoothness of opening and closing of the first clamping part 11 and the second clamping part 12.

[0059] In some optional embodiments, a blade clamp 100 provided by an embodiment of the present application has a second rotation center bb between the first clamping portion 11 and the connecting rod assembly 22, a third rotation center cc between the second clamping portion 12 and the connecting rod assembly 22, a fourth rotation center dd between the telescopic member 21 and the connecting rod assembly 22, and a distance from the third rotation center cc to the second rotation center bb is greater than a distance from the fourth rotation center dd to the second rotation center bb.

[0060] The fourth rotation center dd can be understood as follows: the telescopic member 21 and the connecting rod assembly 22 are connected via the fourth rotation shaft, and the axis of the fourth rotation shaft can be understood as the fourth rotation center dd.

[0061] The fourth rotating axis, the first rotating axis, the second rotating axis and the third rotating axis are parallel to each other.

[0062] The blade clamp 100 provided in one embodiment of the present application, through the above-mentioned arrangement, enables the telescopic member 21 to be arranged between the first clamping part 11 and the second clamping part 12, so that the telescopic member 21 can achieve the driving requirement of relative rotation of the first clamping part 11 and the second clamping part 12 under a smaller telescopic stroke, thereby reducing the driving difficulty.

The driving component 20 drives the first clamping part 11 to rotate relative to the second clamping part 12 and makes the maximum rotation angle greater than or equal to 90°, so that the blade can be installed between the first clamping part 11 and the second clamping part 12 through the opening formed by the maximum angle after rotation, or separated from the first clamping part 11 and the second clamping part 12. During the disassembly and assembly process, the blade can maintain a sufficiently large safety distance from the first clamping part 11 and the second clamping part 12, reducing the difficulty of disassembly and assembly of the blade, effectively avoiding the risk of the blade being scratched and damaged during the disassembly and assembly process, and ensuring the reliability of blade transportation.

[0091] In some optional embodiments, the blade transportation system provided in one embodiment of the present application further includes a transportation device including a transportation vehicle, and the blade transportation system further includes an adapter frame 200, the adapter frame 200 is arranged on the transportation vehicle, and the blade clamp 100 is connected to the adapter frame 200.

[0092] With this arrangement, when a blade is hoisted from another transport device, such as a transport ship, to a transport vehicle, or when it is hoisted from a transport vehicle to a transport ship, the drive component 20 drives the first clamping portion 11 to rotate relative to the second clamping portion 12, with the maximum rotation angle being greater than or equal to 90°. This ensures that the blade can be hoisted straight up and down, reducing the difficulty of assembly and disassembly of the blade and preventing the risk of scratches and damage to the blade during assembly and disassembly. The corresponding adapter frame 200 facilitates the connection between the blade clamp 100 and the transport vehicle.

[0093] Although the present application has been described with reference to preferred embodiments, various modifications may be made thereto and components may be substituted with equivalents without departing from the scope of the present application. In particular, the various technical features described in the various embodiments may be combined in any manner as long as there are no structural conflicts. The present application is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
