[0033] The orientation terms appearing in the following description are all the directions shown in the drawings, and do not limit the specific structures of the blade holder, transportation system, wind farm, and wind turbine generator of the present utility model. In the description of the present utility model, 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 may be a fixed connection, a detachable connection, or an integral connection; it may be directly connected or indirectly connected. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0034] In the current wind power generation industry, the increase in blade size has brought challenges in transportation, especially the transportation problem of ultra-long blades. During the blade transportation process, the stability of the blade holder for clamping and fixing the blade is crucial.

[0035] However, for the blade holders in the related art, when in use, there is a problem that the fixed cavity form cannot closely fit the blade surface, which may lead to risks such as the blade moving during transportation and affect the reliability of blade transportation.

[0036] Based on this, an embodiment of the present application provides a blade retainer, which can ensure the clamping and fixing effect on the blade and ensure the reliability of blade transportation.

[0037] As Figures 1 to 3 shown, an embodiment of the present application provides a blade retainer including a base body 10 and a clamping assembly 20. The base body 10 includes a first seat body 11 and a second seat body 12 which are oppositely arranged. The clamping assembly 20 includes a first clamping member 21 arranged on the first seat body 11 and a second clamping member 22 arranged on the second seat body 12. The first clamping member 21 and the second clamping member 22 are configured to clamp and fix the blade. Among them, at least a part of the first clamping member 21 has degrees of freedom of movement and rotation relative to the first seat body 11, and / or at least a part of the second clamping member 22 has degrees of freedom of movement and rotation relative to the second seat body 12.

[0038] The blade generally includes a blade root, a blade tip which are oppositely arranged along its own length direction, and a blade body located between the blade root and the blade tip. The blade body support device is used to support the blade body of the blade.

[0039] The first seat body 11 and the second seat body 12 can be connected to each other or can be independently arranged, and are preferably connected to each other.

[0040] At least a part of the first clamping member 21 can have a degree of freedom of movement in one direction or can have degrees of freedom of movement in multiple directions relative to the first seat body 11. Optionally, at least a part of the first clamping member 21 can have a degree of freedom of rotation in one direction relative to the first seat body 11. Of course, it can also have degrees of freedom of rotation in multiple directions.

[0041] And / or, at least a part of the second clamping member 22 can have a degree of freedom of movement in one direction or can have degrees of freedom of movement in multiple directions relative to the second seat body 12. Optionally, at least a part of the second clamping member 22 can have a degree of freedom of rotation in one direction relative to the first seat body 11. Of course, it can also have degrees of freedom of rotation in multiple directions.

[0042] The blade holder provided by an embodiment of the present application, when in use, can place the blade between the first seat body 11 and the second seat body 12. Since at least part of the first clamping member 21 has degrees of freedom of movement and rotation relative to the first seat body 11, and / or at least part of the second clamping member 22 has degrees of freedom of movement and rotation relative to the second seat body 12, when the first clamping member 21 and the second clamping member 22 clamp and fix the blade, at least part of the first clamping member 21 can be rotated relative to the first seat body 11, and / or at least part of the second clamping member 22 can be rotated relative to the second seat body 12, ensuring that the first clamping member 21 and the second clamping member 22 can adapt to the blade profile and increasing the contact area with the profile. By moving at least part of the first clamping assembly 20 relative to the first seat body 11, and / or moving at least part of the second clamping part relative to the second seat body 12, the pressure on the blade surface is increased, so that the first clamping member 21 and / or the second clamping member 22 closely adhere to the windward surface and the leeward surface of the blade, reducing the risk of the blade moving during transportation and ensuring the reliability of blade transportation.

[0043] In some optional embodiments, for the blade holder provided by an embodiment of the present application, the first seat body 11 and the second seat body 12 are opposite to each other along the first direction X. At least part of the first clamping member 21 has a degree of freedom of movement along the first direction X relative to the first seat body 11, and / or at least part of the second clamping member 22 has a degree of freedom of movement along the first direction X relative to the second seat body 12.

[0044] When clamping a blade, the first direction X can be the thickness direction of the blade.

[0045] Optionally, at least part of the first clamping member 21 and at least part of the second clamping member 22 can be driven by a telescopic structure, a spiral structure, etc., so that at least part of the first clamping member 21 can have a degree of freedom of movement in the first direction X relative to the first seat body 11, and at least part of the second clamping member 22 can have a degree of freedom of movement in the first direction X relative to the second seat body 12.

[0046] The blade holder provided by an embodiment of the present application, through the above settings, can make at least part of the first clamping member 21 move in the first direction X towards or away from the second seat body 12. Correspondingly, at least part of the second clamping part can move in the first direction X towards or away from the first seat body 11, so that the first clamping part and the second clamping part can apply sufficient clamping force to the blade. After clamping the blade, the degrees of freedom of rotation of the first clamping member 21 and the second clamping member 22 can also be locked, effectively ensuring the stability of the blade during transportation.

[0047] In some optional embodiments, for the blade holder provided by an embodiment of the present application, the first seat body 11 and the second seat body 12 can enclose to form a cavity 13 that runs through in the second direction Y. The blade can extend into the cavity 13. At least part of the first clamping member 21 is located in the cavity 13 and the rotation axis relative to the first seat body 11 extends along the second direction Y, and / or at least part of the second clamping member 22 is located in the cavity 13 and the rotation axis relative to the second seat body 12 extends along the second direction Y.

[0048] The cavity 13 arranged around the first direction X can be closed or partially open. The first clamping member 21 and the second clamping member 22 can be at least partially located in the cavity 13, such that at least part of the first clamping member 21 located in the cavity 13 has degrees of freedom of movement and rotation relative to the first seat body 11, and such that at least part of the second clamping member 22 located in the cavity 13 has degrees of freedom of movement and rotation relative to the second seat body 12.

[0049] The rotation axis of at least part of the first clamping member 21 rotating relative to the first seat body 11 extends along the second direction Y, and the rotation axis of at least part of the second clamping member 22 rotating relative to the second seat body 12 extends along the second direction Y.

[0050] Optionally, the first direction X and the second direction Y intersect, and can be perpendicular to each other. When the blade holder clamps the blade, the second direction Y can be the length direction of the blade.

[0051] For the blade holder provided by an embodiment of the present application, through the above settings, it is beneficial to ensure the rotation freedom of the first clamping member 21 relative to the first seat body 11, and ensure the rotation freedom of the second clamping member 22 relative to the second seat body 12, which is beneficial to increase the contact area with the blade, provide greater frictional resistance, and ensure the reliability of clamping and fixing the blade.

[0052] In some optional embodiments, one end of the first seat body 11 and the second seat body 12 in the third direction Z can be rotatably connected and the other end can be detachably connected. By rotating the first seat body 11 and the second seat body 12 relative to each other, the first clamping member 21 and the second clamping member 22 are driven to rotate relative to each other, so as to realize the clamping and release of the blade. Optionally, the detachable connection end of the first seat body 11 and the second seat body 12 can be locked or unlocked through a locking member.

[0053] Optionally, the third direction Z intersects with the first direction X and the second direction Y, and can be perpendicular to each other. When the blade is clamped, the third direction Z can be the chord direction of the blade.

[0054] In some alternative embodiments, for the blade holder provided by an embodiment of the present application, the first clamping member 21 includes a first clamping unit 21a, and at least one first clamping unit 21a has degrees of freedom of movement and rotation relative to the first base body 11.

[0055] In some alternative embodiments, the first clamping units 21a included in the first clamping member 21 may be two, three or more spaced-apart clamping units.

[0056] Among the first clamping units 21a included in the first clamping member 21, at least a part of one of the first clamping units 21a may have degrees of freedom of movement and rotation relative to the first base body 11. It is also possible that at least a part of two or more first clamping units 21a have degrees of freedom of movement and rotation relative to the first base body 11.

[0057] When clamping the blade, the first clamping units 21a of the first clamping member 21 may be at least partially distributed along the third direction Z.

[0058] For the blade holder provided by an embodiment of the present application, by making the first clamping member 21 include two or more spaced-apart first clamping units 21a, it is possible to cooperate with the second clamping member 22 to achieve multi-point support for at least one of the windward surface and the leeward surface of the blade, improve the stability of clamping and fixing, facilitate ensuring the stability of the blade relative to the base body 10 after being clamped and fixed, and ensure the reliable transportation of the blade.

[0059] In some alternative embodiments, for the blade holder provided by an embodiment of the present application, the first clamping unit 21a includes a first driving part 211 and a first clamping body 212. The first clamping body 212 is rotatably connected to the first driving part 211 and is configured to clamp the blade, and the first driving part 211 is arranged on the first base body 11 and is configured to drive the first clamping body 212 to move relative to the first base body 11.

[0060] The first driving part 211 includes, but is not limited to, structures such as a telescopic cylinder and a screw rod. The first clamping body 212 and the first driving part 211 may be connected by means such as shaft hinge, ball hinge, and universal joint connection.

[0061] For the blade holder provided by an embodiment of the present application, the first clamping unit 21a adopts the above structural form, and can use the first clamping body 212 to contact the blade and jointly clamp and fix the blade with the second clamping assembly 20. Since the first driving part 211 drives the first clamping body 212 to move relative to the first seat body 11, it is beneficial to adjust the clamping force of the first clamping body 212 on the blade. Moreover, the first clamping body 212 is rotatably connected to the first driving part 211, so that when clamping and fixing the blade, the angle of the first clamping body 212 relative to the first seat body 11 and the first driving part 211 can be adjusted to better fit the blade profile, increase the contact area, and then drive the first clamping body 212 to move through the first driving part 211 to clamp and fix the blade, which can ensure the clamping and fixing effect on the blade and ensure the reliability of blade transportation.

[0062] In some optional embodiments, the first driving part 211 includes a first telescopic cylinder 2111, and the first telescopic cylinder 2111 is connected between the first seat body 11 and the first clamping body 212.

[0063] The first telescopic cylinder 2111 can be a pneumatic cylinder, a hydraulic cylinder or an electric cylinder.

[0064] One of the cylinder body and the cylinder rod of the first telescopic cylinder 2111 can be connected to the first seat body 11 and the other can be connected to the first clamping body 212. Exemplarily, the cylinder body of the first telescopic cylinder 2111 can be fixedly connected to the first seat body 11 and its cylinder rod can be rotatably connected to the first clamping body 212.

[0065] For the blade holder provided by an embodiment of the present application, through the above settings, the first clamping body 212 can be driven to move by the extension and shortening of the first telescopic cylinder 2111, and the first telescopic cylinder 2111 can be directly or indirectly rotatably connected to the first clamping body 212, so that the first clamping body 212 has degrees of freedom of movement and rotation relative to the first seat body 11, ensuring the clamping and fixing of the blade holder.

[0066] It can be understood that the cylinder body or the cylinder rod of the first telescopic cylinder 2111 of part of the first clamping units 21a can be directly rotatably connected to the first clamping body 212 to meet the movement and rotation requirements of the first clamping body 212 relative to the first seat body 11.

[0067] Certainly, in some optional embodiments, for the blade holder provided by an embodiment of the present application, the first driving part 211 of at least one first clamping unit 21a further includes a transmission rod 2112. One end of the transmission rod 2112 is rotatably connected to the first seat body 11 and the other end is rotatably connected to the first telescopic cylinder 2111, and the first clamping body 212 is rotatably connected to the transmission rod 2112.

The first clamping body 212 can be rotatably connected to the transmission rod 2112 through the third rotating shaft 215. Optionally, the first rotating shaft 213, the second rotating shaft 214, and the third rotating shaft 215 are spaced apart from each other and arranged in parallel.

[0069] For the blade holder provided in an embodiment of the present application, through the above settings, it can make up for the insufficient height of the first seat body 11, utilize the transmission rod 2112 to realize the transmission of the power of the first telescopic cylinder 2111, drive the transmission rod 2112 to rotate through the elongation or shortening of the first telescopic cylinder 2111, so that the transmission rod 2112 can rotate relative to the first seat body 11 and drive the first clamping body 212 to move relative to the first seat body 11. At the same time, the first clamping body 212 is rotatably connected to the transmission rod 2112, so that the first clamping body 212 can rotate relative to the first seat body 11, which can also ensure the requirements for the movement and rotation degrees of freedom of the first clamping body 212, and the base body 10 has sufficient space to install the first clamping assembly 20.

[0070] As Figures 1 to 4 shown, in some optional embodiments, for the blade holder provided in an embodiment of the present application, the first driving parts 211 included in the first clamping unit 21a are arranged in pairs and symmetrically distributed on both sides of the first seat body 11, and the first driving parts 211 arranged in pairs are both rotatably connected to the first clamping body 212.

[0071] The first driving part 211 can include the first telescopic cylinder 2111. Of course, the first driving part 211 can also include the first telescopic cylinder 2111 and the transmission rod 2112. The specific connection manner with the first clamping body 212 can adopt the connection form in the above embodiment, and will not be repeated here.

[0072] The first driving parts 211 arranged in pairs of the first clamping unit 21a can be rotatably connected to the first clamping body 212 through the same rotating shaft.

[0073] For the blade holder provided in an embodiment of the present application, by arranging the first driving parts 211 included in the first clamping unit 21a in pairs and symmetrically distributing them on both sides of the first seat body 11, and both the first driving parts 211 arranged in pairs are rotatably connected to the first clamping body 212, it can ensure the stability of driving the first clamping body 212 and ensure the reliability of blade transportation.

[0074] In some alternative embodiments, for the blade holder provided in an embodiment of the present application, the second clamping member 22 includes a second driving portion 221 and a second clamping body 222. The second clamping body 222 is rotatably connected to the second driving portion 221 and is configured to clamp the blade. The second driving portion 221 is disposed on the second seat body 12 and is configured to drive the second clamping body 222 to move relative to the second seat body 12.

[0075] The second driving portion 221 includes, but is not limited to, structures such as telescopic cylinders and screw rods. The second clamping body 222 and the second driving portion 221 may be connected by means such as shaft hinges, ball hinges, and universal joint connections.

[0076] It can be understood that the above embodiments of the present application are all exemplified by taking the first driving portion 211 including the first telescopic cylinder 2111 as an example. However, it is not limited thereto. In some embodiments, the first driving portion 211 may also include structures such as linear motors, the cooperative structure of rotary motors and scissor forks, etc., which can achieve length changes and directly or indirectly drive the first clamping body 212 to move relative to the first seat body 11.

[0077] For the blade holder provided in an embodiment of the present application, the second clamping assembly 20 adopts the above structural form, and can use the second clamping body 222 to contact the blade and jointly clamp and fix the blade with the first clamping assembly 20. Since the second driving portion 221 drives the second clamping body 222 to move relative to the second seat body 12, it is beneficial to adjust the clamping force of the second clamping body 222 on the blade. Moreover, the second clamping body 222 is rotatably connected to the second driving portion 221, so that during the process of clamping the blade, the angle of the second clamping body 222 relative to the second seat body 12 and the second driving portion 221 can be adjusted to better fit the blade profile and increase the contact area. Then, the second driving portion 221 drives the second clamping body 222 to move to clamp and fix the blade, which can ensure the clamping and fixing effect on the blade and ensure the reliability of blade transportation.

[0078] In some alternative embodiments, for the blade holder provided in an embodiment of the present application, the second driving portion 221 includes at least one of a second telescopic cylinder and a driving screw rod.

[0079] The second driving part 221 may include a second telescopic cylinder. The second telescopic cylinder may be connected between the second seat body 12 and the second clamping body 222. The second telescopic cylinder and the second seat body 12 may be fixedly connected and rotatably connected to the second clamping body 222. The telescopic movement of the second telescopic cylinder can drive the second clamping body 222 to move relative to the second seat body 12. And the second telescopic cylinder is rotatably connected to the second seat body 12, which can drive the second clamping body 222 to rotate relative to the second seat body 12, so as to satisfy that the second clamping body 222 has degrees of freedom of movement and rotation relative to the second seat body 12, and better fit the blade profile. By extending the second telescopic cylinder, the blade can be locked and fixed, ensuring the clamping stability of the blade.

[0080] Certainly, in some embodiments, the second driving part 221 may also include a driving screw. The driving screw is rotatably connected to the second clamping body 222. The driving screw and the second seat body 12 may be in clearance fit with each other. The relative position between the driving screw and the second seat body 12 after adjustment is fixed by a pair of locking nuts arranged on the driving screw. For example, the relative position between the driving screw and the second seat body 12 can be shortened by clamping and fixing the second seat body 12 with two locking nuts. When it is necessary to adjust the relative position between the driving screw and the second seat body 12 to drive the second clamping body 222 to move, the two locking nuts can be unlocked, so that the driving screw can move relative to the second seat body 12 and drive the second clamping body 222 to move to a proper position, and then the locking nuts are tightened to lock the position of the adjusted driving screw again, which can also ensure the driving requirements for the degrees of freedom of movement and rotation of the second clamping body 222.

[0081] In some alternative embodiments, the blade holder further includes a leading edge fitting 30 and a trailing edge fitting 40. The leading edge fitting 30 is rotatably connected to the base body 10 and is configured to cooperate with the leading edge of the blade. The trailing edge fitting 40 is fixedly connected to the base body 10 and is configured to cooperate with the trailing edge of the blade. Through the above arrangement, the stability of the blade during transportation can be further improved.

[0082] On the other hand, an embodiment of the present application further provides a blade transportation system, including a transportation device and the above-mentioned blade holder, and the blade holder is arranged on the transportation device.

[0083] The blade holder can be directly or indirectly connected to the transportation device. The blade is clamped and fixed by the blade holder, and the blade is transported to a predetermined position by the transportation device. The transportation device includes but is not limited to a transport vehicle or a transport ship.
