Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0022] Please refer to Figures 1-3, the present utility model provides a technical solution: a blade conveyor for wind power generation, including a placement plate 1 and a lifting ring 2 fixedly installed on the upper surface of the placement plate 1. An accommodation groove 3 is formed on the upper surface of the placement plate 1, and a protective pad 4 is fixedly connected to the inner wall of the accommodation groove 3. Three groups of sliding grooves 5 are formed on both the front and rear sides of the upper surface of the placement plate 1. A slider 6 is slidably connected inside each group of sliding grooves 5. A moving plate 7 and a linkage plate 16 are respectively fixedly connected to the upper and lower surfaces of the three sliders 6 on the front side and the upper and lower surfaces of the three sliders 6 on the rear side. A fixed column 8 is fixedly connected to the left side of the inner surface of each group of moving plates 7, and a fixed clamping plate 9 is fixedly connected to the inner surface of each group of fixed columns 8. A limiting component is installed on the right side of the outer surface of each group of moving plates 7. The limiting component includes a fixed cylinder 10 fixedly installed on the right side of the outer surface of the moving plate 7. A lead screw 11 threadedly connected to the moving plate 7 is threadedly connected inside each group of fixed cylinders 10. The inner end of each group of lead screws 11 is rotatably connected to a moving clamping plate 12 through a bearing. Rubber pads are fixedly connected to the inner surfaces of each group of fixed clamping plates 9 and the inner surfaces of each group of moving clamping plates 12. Three limiting shafts 15 that are all movably inserted into the moving plate 7 are fixedly connected to the outer surface of each group of moving clamping plates 12. A driving wheel 14 is fixedly sleeved on the outer end of each group of lead screws 11. A driving shaft 17 is fixedly inserted into the middle of the lower surface of each group of linkage plates 16. A driving component is installed on the lower surface of the placement plate 1. The driving component includes an electric push rod 19 and a slide rail 18 fixedly installed on the lower surface of the placement plate 1. A slide bar 20 is slidably connected to the outer surface of the slide rail 18. A driving block 21 whose left side surface is fixedly connected to the output end of the electric push rod 19 is fixedly connected to the lower surface of the slide bar 20. Driving plates 22 are fixedly connected to both the front and rear surfaces of the slide bar 20. A driving groove 23 adapted to the driving shaft 17 is formed on the lower surface of each group of driving plates 22. Two reinforcing blocks 13 whose upper surfaces are fixedly connected to the upper surfaces of the driving plates 22 are fixedly connected to the lower surface of the slide bar 20.
[0023] In the present utility model, in order to enable the driving shaft 17 to drive the linkage plate 16 smoothly, the outer diameter of the driving shaft 17 is set to be one-half of the width of the linkage plate 16, and the center line of the driving shaft 17 coincides with the vertical center line of the adjacent linkage plate 16, so that the driving shaft 17 can apply the acting force to the adjacent linkage plate 16 more evenly and effectively, greatly improving the smoothness of the driving shaft 17 driving the adjacent linkage plate 16 to move.
[0024] In the present utility model, in order to lift the placement plate 1 stably, the number of lifting rings 2 is set to four groups. The two lifting rings 2 on the front side and the two lifting rings 2 on the rear side are symmetric with each other with the longitudinal center line of the placement plate 1 as the center, so that the four lifting rings 2 can apply acting forces to the placement plate 1 evenly and effectively, thereby effectively improving the stability of the movement of the placement plate 1.
[0025] In the present utility model, in order to enable the limiting shaft 15 to uniformly limit the adjacent movable clamping plates 12, the material of the limiting shaft 15 is set to stainless steel, thereby improving the service life of the limiting shaft 15. And three adjacent groups of limiting shafts 15 are arranged in a circular array centered on the center line of the adjacent movable clamping plates 12, so that the three adjacent groups of limiting shafts 15 can uniformly and effectively limit the adjacent movable clamping plates 12, greatly improving the smoothness of the movement of the movable clamping plates 12.
[0026] The electrical components appearing in this article are all electrically connected to the external main controller and 220V mains power, and the main controller can be a conventional known device such as a computer for control.
[0027] The working principle of the present utility model is as follows:
[0028] S1. Fix the blade. Place the blade on the protective pad 4 in the placement groove 3, and then start the electric push rod 19. The output end of the electric push rod 19 extends to drive the driving block 21, the sliding bar 20 and the driving plates 22 on the front and rear sides to move to the right along the track of the slide rail 18 at the same time. Thus, the driving plates 22 on the front and rear sides can respectively apply forces to the driving shafts 17 on the front and rear sides through the driving grooves 23 on the front and rear sides at the same time. Furthermore, the driving shafts 17 on the front and rear sides can respectively drive the linkage plates 16, the sliders 6 and the moving plates 7 on the front and rear sides to move inward along the track of the chute 5 at the same time, so that the fixed clamping plates 9 and the movable clamping plates 12 on the front and rear sides can move inward at the same time. Since the thicknesses of the two ends of the blade for wind power generation are different, when the inner side of the fixed clamping plate 9 contacts the blade to fix the thicker end of the blade, the inner side of the movable clamping plate 12 has not yet contacted the thinner end of the blade. At this time, rotate the driving wheel 14, and the driving wheel 14 drives the lead screw 11 to rotate clockwise, so that the lead screw 11 can drive the movable clamping plate 12 and the limiting shaft 15 to move inward relative to the moving plate 7 and the fixed cylinder 10 to fix the thinner end of the blade.
[0029] S2. Dismantle the blade. Use an external hoisting device to lift the placement plate 1 and the blade. When reaching the placement position, start the electric push rod 19. The output end of the electric push rod 19 contracts to drive the driving block 21, the sliding bar 20 and the driving plates 22 on the front and rear sides to move to the left along the track of the slide rail 18 at the same time. Thus, the driving shafts 17 on the front and rear sides can respectively drive the linkage plates 16, the sliders 6 and the moving plates 7 on the front and rear sides to move outward along the track of the chute 5 at the same time, so that the fixed clamping plates 9 and the movable clamping plates 12 can move outward at the same time, thereby conveniently releasing the fixation of the blade.
[0030] In summary, for the blade conveyor for wind power generation, by setting the output end of the electric push rod 19 to contract, it can effectively drive the driving block 21, the sliding strip 20 and the driving plate 22 to move to the left along the track of the slide rail 18, so that the moving plate 7 can conveniently and stably drive the fixed clamping plate 9 and the moving clamping plate 12 to move outward along the track of the chute 5, so that the two groups of fixed clamping plates 9 and the two groups of moving clamping plates 12 can simultaneously release the fixation of the blade, thereby improving the convenience of blade disassembly and the practicality of the conveyor. By setting the driving plates 22 on the front and rear sides to move along the track of the slide rail 18 simultaneously with the movement of the sliding strip 20, the driving shafts 17 on the front and rear sides can simultaneously drive the linkage plates 16, the sliders 6 and the moving plate 7 on the front and rear sides to move inward along the track of the chute 5, so that the fixed clamping plate 9 and the moving clamping plate 12 can move inward simultaneously to fix the blade. After the fixed clamping plate 9 completes the fixation of one end of the blade, only by rotating the driving wheel 14 can the moving clamping plate 12 stably fix the other end of the blade, greatly improving the stability of blade fixation. By setting the driving wheel 14 to be manually rotated, the driving wheel 14 can conveniently and stably drive the lead screw 11 to rotate. The lead screw 11 is threadedly connected to the fixed cylinder 10 and the moving plate 7, and the lead screw 11 is rotatably connected to the moving clamping plate 12. When the lead screw 11 is rotated, the moving clamping plate 12 can stably move inward in the horizontal direction, and the limiting shaft 15 is movably inserted into the moving plate 7 to limit the moving clamping plate 12, which effectively improves the smoothness of the movement of the moving clamping plate 12.

[0032] The above describes the preferred embodiments of the present patent in detail, but the present patent is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of the present patent.
