[0040] Features and exemplary embodiments of various aspects of the present application will be described in detail below. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the application. However, it will be apparent to one of ordinary skill in the art that the application can be practiced without some or all of these specific details. The description of the embodiments is merely illustrative of the application and is not intended to limit the scope of the application, as defined by the appended claims. In the following description, specific terminology and description have been set forth in order to provide a thorough understanding of the application. However, the application readily suggests techniques that can be used in conjunction with the specific language set forth in order to practice the application. As used herein, the article "a" is intended to include one or more items.

[0041] The orientation words appearing in the following description are the directions shown in the drawings, and are not intended to limit the specific structure of the blade body support assembly and the transport system of the present application. In the description of the present application, it should also be noted that, unless otherwise explicitly specified and limited, the terms "mounting", "connecting" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be directly connected, or indirectly connected. For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0042] In the global wind power industry, as the size of wind turbine generators continues to expand, more stringent overhanging requirements are put forward for the transport equipment for transporting blades, such as transport vehicles.

[0043] As Figure 1As shown, the blade 50 in the related art is transported, and a support assembly for supporting the blade body 53 of the blade 50 needs to be set according to different models of the blade 50 when the blade 50 is transported. The support assembly for supporting and holding the blade body has diversified structures and diversified interfaces, so that the interface of the transportation equipment needs to be modified to meet the connection and fixation of different support assemblies for the blade body, which has high modification cost. If not modified, direct connection will be not conducive to the connection with the transportation equipment, and the reliability of the blade transportation is affected.

[0044] Based on this, one embodiment of the present application provides a blade body support assembly and a transportation system. The blade body support assembly can meet the support of the blade 50 and the connection between the blade 50 and the first transportation equipment 60, and ensure the reliability of the transportation of the blade 50.

[0045] As shown, Figures 1-2 One embodiment of the present application provides a blade body support assembly for the blade 50. The blade 50 includes a blade root 51, a blade tip 52, and a blade body 53 between the blade root 51 and the blade tip 52. The blade body support assembly includes a connecting structure 200 and a first blade body holder 100. The connecting structure 200 has opposite first and second ends 202 in a first direction X. The first end is used to connect with the first transportation equipment 60. The first blade body holder 100 is arranged at the second end 202 and connected with the connecting structure 200. The first blade body holder 100 is used to support and fix the blade body 53.

[0046] The connecting structure 200 can include a plate structure or a frame structure.

[0047] When the blade body support assembly is matched with the blade 50, the first direction X can be understood as the thickness direction of the blade 50.

[0048] The connecting structure 200 can be provided with a connecting interface matched with a reserved interface of the first transportation equipment 60, which can be a flange connecting interface or a lock pin connecting interface.

[0049] The first blade body holder 100 is used to support and fix the blade body 53, which can be partially matched with a part of the profile of the blade body 53. It can be connected with the blade body 53 in a clamping or locking manner.

[0050] The first transportation device 60 can be a transportation vehicle. The transportation vehicle mentioned above and below can be an integrated vehicle or a split vehicle. The split vehicle can not be provided with an intermediate vehicle plate beam, and two or more parts of the transportation vehicle are arranged in a split manner. When transporting an ultra-long wind power blade 50, the split transportation vehicle can more flexibly meet the requirements of different countries and regions for the ultra-long suspension regulations. The split transportation vehicle allows the blade 50 to be directly fixed at a position meeting the ultra-long suspension requirements, thereby improving the transportation efficiency and safety.

[0051] The connecting structure 200 has opposite first and second ends 201 and 202 in the first direction X. The first end 201 can be connected to the first transportation device 60. An interface matching a reserved interface of the first transportation device 60 can be arranged on the first end 201 to be connected. The first blade holder 100 for supporting and fixing the blade 53 can be connected to the connecting structure 200. Different interfaces can be arranged on the connecting structure 200 to adapt to different models of the blade 50. That is, by setting the connecting structure 200 to adapt to the structure of the first blade holder 100, the connection requirement between the first blade holder 100 and the first transportation device 60 is ensured, and the structure of the first transportation device 60 does not need to be modified, thereby ensuring the reliability of the transportation of the blade 50.

[0052] In some optional embodiments, the connecting structure 200 includes a first region and a second region distributed along a second direction Y. The first blade holder 100 is arranged on a part of the second end 202 located in the first region. A part of the second end 202 located in the second region is used to connect a second blade holder. The second blade holder is used to support and fix the blade 53.

[0053] The second direction Y can be perpendicular to the first direction X. Optionally, when the first blade holder 100 supports and fixes the blade 50, the second direction Y can be the length direction of the blade 50.

[0054] The connecting structure 200 is divided into the first and second regions along the second direction Y. After the first blade holder 100 is connected to the part of the second end 202 located in the first region, the space of the second region is reserved. The second blade holder carried from another transportation device can be connected to the part of the second end 202 located in the second region, thereby ensuring the connection requirement of the second blade holder.

[0055] In some optional embodiments, the connecting structure 200 includes a first region and a second region distributed along a second direction Y. The first blade holder 100 is arranged on a part of the second end 202 located in the first region. A part of the second end 202 located in the second region is used to connect a second blade holder. The second blade holder is used to support and fix the blade 53.

[0056] The interface portion 203 includes one of a plug hole, a plug pin, and a docking flange. The interface portion 203 and the second blade retainer can be detachably connected by plugging or by inserting fasteners such as bolts into the docking flange.

[0057] The blade support assembly provided in one embodiment of the present application facilitates the connection and disassembly requirements of the second blade retainer transferred from other transportation equipment or the like by providing an interface portion 203 in the second area.

[0058] like Figures 1-3 As shown, in some optional embodiments, the blade support assembly provided in the above-mentioned embodiments of the present application further includes an attitude adjustment member 30, which is connected to the connecting structure 200, and the attitude adjustment structure is used to connect to the first transport equipment 60 so that the attitude of the connecting structure 200 and the first blade retainer 100 relative to the first transport equipment 60 can be adjusted.

[0059] Optionally, the connection structure 200 may be indirectly connected to the first transport device 60 via an attitude adjustment member 30. For example, by providing the attitude adjustment member 30, the movement and / or rotation of the entirety formed by the connection structure 200 and the first blade airfoil retainer 100 relative to the first transport device 60 can be adjusted. When a second blade airfoil retainer is provided on the connection structure 200, adjusting the connection structure 200 can adjust the movement and / or rotation of the entirety formed by the connection structure 200, the first blade airfoil retainer 100, and the second blade airfoil retainer relative to the first transport device 60.

[0060] The blade support assembly provided by one embodiment of the present application can, through the above-mentioned arrangement, adjust the posture of the whole formed by the connecting structure 200 and the first blade retainer 100 relative to the first transport equipment 60 according to at least one of the turning requirements, the inclination angle requirements, the height requirements, etc., or adjust the posture of the whole formed by the connecting structure 200, the first blade retainer 100, and the second blade retainer relative to the first transport equipment 60, thereby further ensuring the transportation reliability of the blade support assembly.

[0061] In some optional embodiments, the blade support assembly provided by one embodiment of the present application, the attitude adjustment member 30 includes a rotation adjustment assembly, which is connected to the connecting structure 200 to drive the connecting structure 200 and the first blade retainer 100 to rotate as a whole relative to the first transport equipment 60.

[0062] The rotation adjusting assembly can have a rotation freedom in at least one direction. For example, the connection structure 200 and the first blade body holder 100 as a whole can rotate the blade 50 as a whole in a first rotation direction by a predetermined angle, and the extension direction of the rotation axis of the first rotation direction can be along the third direction Z, which can be understood as the chord direction of the blade 50 when the blade 50 is installed. In this way, the pitch angle of the blade tip 52 can be changed to ensure the reliability of transportation. Of course, the rotation adjusting assembly can also rotate the blade 50 as a whole in a second rotation direction by a predetermined angle, and the extension direction of the rotation axis of the second rotation direction can be the thickness direction of the blade 50. In some other embodiments, the rotation adjusting assembly can also rotate the blade 50 as a whole in a third rotation direction by a predetermined angle. The extension direction of the rotation axis of the third rotation direction can be the length direction of the blade 50.

[0063] The blade body support assembly provided by one embodiment of the present application can rotate the blade 50 in at least one direction according to the transportation requirements, thereby ensuring the reliability of transportation of the blade 50.

[0065] Optionally, the blade body support assembly provided by one embodiment of the present application can include three rotation adjusting parts, which can be arranged in sequence and connected in sequence, for example, can be distributed in sequence along the first direction X, and the rotation adjusting part located at the top end can be connected to the connection structure 200, and the rotation adjusting part located at the bottom end can be directly or indirectly connected to the first transportation device 60. Each rotation adjusting part can include a first seat body and a second seat body hinged to each other through a hinge shaft. Among the plurality of rotation adjusting parts, the rotation axis of one of the rotation adjusting parts can extend along the first direction X, the rotation axis of another rotation adjusting part can extend along the second direction Y, and the rotation axis of the other rotation adjusting part can extend along the third direction Z. Of course, the number of rotation adjusting parts is not limited to three, and can be one, two or more than three.

[0066] The blade body support assembly provided by one embodiment of the present application can rotate the blade 50 in at least one direction according to the transportation requirements, thereby ensuring the reliability of transportation of the blade 50.

[0067] In some optional embodiments, the blade body support assembly provided by one of the embodiments of the present application includes the posture adjusting member 30, which is connected with the connecting structure 200 to drive the connecting structure 200 and the first blade body holder 100 to move relative to the first conveying device 60 as a whole.

[0068] The movement adjusting assembly can drive the connecting structure 200 to have a movement degree of freedom in at least one direction, for example, at least one of the first direction X, the second direction Y and the third direction Z. Optionally, the first direction X can be the thickness direction of the blade 50, the second direction Y can be the length direction of the blade 50, and the third direction Z can be the chord direction of the blade 50.

[0069] The blade body support assembly provided by one of the embodiments of the present application can ensure that the blade body support assembly can drive the blade body 53 of the blade 50 to have a movement degree of freedom in at least one direction, thereby ensuring the conveying reliability of the blade 50.

[0071] For example, at least one of the movement adjusting parts can include a movement rail and a sliding block, and the sliding block can move along the extension direction of the movement rail. The sliding block can be directly or indirectly connected with the connecting structure 200, for example, when the rotating adjusting assembly is included, the sliding block can be connected with the connecting structure 200 through the rotating adjusting assembly.

[0072] For example, at least one of the movement adjusting parts can include a plurality of telescopic cylinders, one of the cylinder body and the steel rod of each telescopic cylinder can be rotationally connected with the first conveying device 60, and the other can be rotationally connected with the other movement adjusting parts or the rotating adjusting assembly, and the movement of the connecting structure 200 and the first blade body holder 100 relative to the first conveying device 60 can be realized by controlling the extension and shortening of the plurality of telescopic cylinders.

[0073] The blade body support assembly provided by one of the embodiments of the present application can ensure that the blade body support assembly can drive the blade body 53 of the blade 50 to have a movement degree of freedom in a plurality of directions, thereby being conducive to adapting to different conveying conditions and ensuring the conveying reliability of the blade 50.

[0081] When the detachable connection end of the first clamping part 11 and the second clamping part 12 is connected, the rotation angle between the first clamping part 11 and the second clamping part 12 is 0°. When the detachable end of the first clamping part 11 and the second clamping part 12 is detached, the maximum rotation angle between them is greater than 90°, which can be any value between 90°-180°, and can be optionally 90°-150°.

[0082] Optionally, the driving component 20 can adopt a structure such as a driving motor, which can be connected to one of the first clamping part 11 and the second clamping part 12 through a base, and the output shaft is connected to the other one of the first clamping part 11 and the second clamping part 12, and the rotation of the output shaft drives the rotation of one of the first clamping part 11 and the second clamping part 12 relative to the other one, so as to achieve the rotation angle driving requirement of the first clamping part 11 and the second clamping part 12. Of course, this is an optional embodiment.

[0083] In some optional embodiments, the vane support assembly provided by an embodiment of the present application can also include the telescopic member 21 and the connecting rod assembly 22, the connecting rod assembly 22 is rotationally connected to the first clamping part 11 and the second clamping part 12 respectively, and the telescopic member 21 is rotationally connected to the first clamping part 11 and the connecting rod assembly 22 respectively.
