[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1 and 4As shown, to achieve the above functions, the technical solution adopted by this utility model is as follows: A clamping device for wind turbine blade support includes a support plate 1, with opposing bases 2 fixedly connected to both ends of the support plate 1. A track 3 is fixedly connected to the top of a set of bases 2, and a clamping mechanism 4 is slidably inserted into the track 3. The clamping mechanism 4 includes a bracket 41 fixedly connected to an angle adjustment mechanism 8. A double-ended lead screw 42 is rotatably connected between the top and bottom walls of the bracket 41. A handle 43 fixedly connected to the double-ended lead screw 42 is rotatably connected to the top wall of the bracket 41. When the handle 43 is grasped and rotated clockwise, the double-ended lead screw 42 is rotated clockwise. The double-ended lead screw 42 is provided with symmetrically arranged threads, and symmetrically arranged nut seats 44 are threadedly connected to the double-ended lead screw 42. The two sets of nut seats 44 are opposite to each other under the rotation of the double-ended lead screw 42. The support 41 has a sliding groove 45 on its side wall, and a nut seat 44 is slidably inserted into the sliding groove 45. The sliding groove 45 limits the movement of the nut seat 44, allowing it to move in a straight line. When the handle 43 is gripped and reversed, it drives the double-ended screw 42 to reverse, thereby driving the two sets of nut seats 44 to move relative to each other and adjust the distance. An electromagnetic suction block 46 is fixed to one end face of the nut seat 44, so that the position of the electromagnetic suction block 46 can be adjusted according to the specifications of the root cylinder of the wind turbine blade, so that the electromagnetic suction block 46 moves to a position that abuts against the inner wall of the root cylinder of the wind turbine blade. A power source located outside the double-ended screw 42 is fixed to the middle of the support 41. The power source can activate the electromagnetic suction block 46 to magnetically fix it to the root cylinder of the wind turbine blade, thereby fixing the root of the wind turbine blade.

[0023] like Figures 1-3 As shown, an angle adjustment mechanism 8 for driving the clamping mechanism 4 to rotate is fixedly connected to a set of bases 2. The angle adjustment mechanism 8 includes an angle adjustment motor 81 fixedly connected to the upper part of one side wall of a set of bases 2. A rotating plate 82 is fixedly connected to the output end of the angle adjustment motor 81. When the angle adjustment motor 81 is turned on, the rotating plate 82 is driven to rotate. The rotating plate 82 is slidably inserted into the track 3. The track 3 is arranged in a ring shape and one end face is provided with an annular groove that is slidably inserted into the rotating plate 82. The annular groove can limit and support the rotating track 3. A support rod 83 is fixedly connected to the other end face of the rotating plate 82. The support rod 83 is fixedly connected to the middle of the bracket 41. The track 3, the support rod 83 and the output end of the angle adjustment motor 81 are concentrically arranged. The support rod 83 drives the clamping mechanism 4 to rotate under the drive of the rotating plate 82, thereby adjusting the angle of the fixed wind turbine blade to adapt to different transport requirements.

[0024] like Figure 1 , 2As shown in Figure 5, another set of bases 2 has opposing supports 5 fixedly connected to both ends. A rotating shaft is rotatably connected to each support 5, and a strap 6 is wound around the rotating shaft. Rotation of the rotating shaft causes the ends of the strap 6 to retract or unfold, thereby adjusting the length of the unfolded section of the strap 6 to secure the wind turbine blades. Both ends of the strap 6 are fixedly connected to the rotating shafts on the two sets of supports 5 respectively. A retraction / untraction mechanism 7 for driving the strap 6 is fixedly connected to the side wall of the other set of bases 2. The retraction / untraction mechanism 7 includes a motor base 71 fixedly connected to one side wall of the other set of bases 2. A rotary motor 72 is fixedly connected to the side wall of the motor base 71. A transmission gear 73 is fixedly connected to the output end of the rotary motor 72. Turning on the rotary motor 72 drives the transmission gear 73 to rotate. A driven gear 74 meshes with the transmission gear 73, and the driven gear 74 is rotatably connected to one side of the motor base 71. The driven gear 74 rotates with the transmission gear 73, and the transmission gear 73 and the driven gear... The other end face of 74 is connected to a drive wheel 75. The drive gear 73 and the driven gear 74 drive the two sets of drive wheels 75 to rotate respectively. The drive belt 76 is slidably attached to the drive wheel 75. One end of the rotating shaft on the support 5 is fixedly connected to a driven wheel 77, and the driven wheel 77 is slidably attached to the drive belt 76. The drive wheel 75 drives the drive belt 76 to rotate, and the driven wheel 77 also rotates accordingly. By turning on the rotary motor 72 to make it rotate forward or backward, the two sets of driven wheels 77 can be driven to rotate relative to each other or in opposite directions. When the two sets of driven wheels 77 rotate relative to each other, the wrapped binding strap 6 can be unfolded to facilitate the wind turbine blade to pass through and be placed under the unfolded binding strap 6. When the two sets of driven wheels 77 rotate in opposite directions, the two ends of the binding strap 6 can be continuously rolled up, and the length of the unfolded section in the middle of the binding strap 6 is shortened, which can bind and fix the wind turbine blade to the top of the base 2 located on the motor base 71, thereby clamping and positioning the transported wind turbine blade.
