[0002] Wind turbine blades are the core components of wind turbines that convert natural wind energy into electricity for wind turbines. They are also the main basis for measuring the design and technical level of wind turbines. If there is a large-scale migration of birds during rotation, the probability of collision with wind turbines will increase. Wind and visibility are also influencing factors, and the loss of repair is very large.

[0003] Therefore, the prior art bird-strike prevention device for wind turbine blades has a publication number of CN219932332U, which includes a red band, a green band, and a black band, which are respectively coated on three different blades, and are respectively located at different positions of the blade tips. The red band, the green band, and the black band made of reflective material are respectively coated on three different blades, and are respectively located at different positions of the blade tips. The red color has the longest light wave, and the red and green colors are the easiest to distinguish, and red and black are warning colors for birds, so that birds are kept away from wind turbines and prevented from striking wind turbines.

[0004] However, the width of the wind turbine blade is limited, so the length of the coated red band, green band and black band is limited. When the wind turbine blade rotates slowly, the coated red band, green band and black band appear as dots when rotating, which will affect the warning effect. Utility Model Content

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] like Figure 1-4 As shown, the bird-strike prevention device for wind turbine blades includes a plurality of wind turbine blades 4, on which a mounting plate 1 is mounted, on which a clamping block 3, a connecting block 16 and a clamping seat 5 are fixedly connected in a direction from far to near from the body of the wind turbine blade 4, the clamping block 3, the connecting block 16 and the clamping seat 5 are staggered, and a plurality of clamping blocks 3, the connecting block 16 and the clamping seat 5 are respectively fixedly connected with a transparent red tube 2, a green tube 8 and a black tube 9. Specifically, by respectively pouring red, green and black pigments into the red tube 2, the green tube 8 and the black tube 9, circular red, green and black warning bands are formed on the wind turbine blade 4, even if the rotation speed of the wind turbine blade 4 is slow, a good warning effect can still be achieved. In addition, the arranged red tube 2, green tube 8 and black tube 9 can also ensure the stability of the edge of the wind turbine blade 4, to prevent the end of one of the wind turbine blades 4 from shaking under the action of wind when the wind turbine blade 4 stops rotating, thereby causing the wind turbine blade 4 to break.

[0023] To further discuss, in order to ensure the brightness of the color: the two ports of the red tube 2, the green tube 8 and the black tube 9 are respectively integrally formed with a feeding tube 10 and a discharging tube 15, several feeding tubes 10 and discharging tubes 15 are distributed in parallel, and the pipe openings are arranged close to the wind turbine blade 4 body, the feeding tubes 10 and the discharging tubes 15 are fixed on the mounting plate 1, and several feeding tubes 10 and the discharging tubes 15 are staggered. Specifically, sealing plugs are installed at the pipe openings of the feeding tubes 10 and the discharging tubes 15 to prevent the internal pigment from flowing out. In addition, cleaning agent can be poured into the red tube 2, the green tube 8 and the black tube 9 through the feeding tube 10 and the discharging tube 15 to remove the residual pigment on the inner wall of the red tube 2, the green tube 8 and the black tube 9, and new pigment is poured regularly to ensure the brightness of the warning tape.

[0024] To further discuss, in order to fix the mounting plate 1: one side of the mounting plate 1 is fixedly connected with a socket 14 which is plugged into the end of the wind turbine blade 4 and connected by bolts, and the other side of the mounting plate 1 is fixed to the wind turbine blade 4 by a binding strap. Specifically, the socket 14 is fixed to the end of the wind turbine blade 4 by bolts, and then the other side of the mounting plate 1 is fixed to the wind turbine blade 4 by a binding strap, to ensure that the mounting plate 1 can be disassembled and assembled.

[0025] Further discussion, in order to increase the warning effect: a solar housing 6 is also fixedly connected to the mounting plate 1, an inner wall of the solar housing 6 is rotatably connected to a gear 11, an end face of the gear 11 is integrally formed with a columnar protrusion that penetrates the other side wall of the solar housing 6, and a warning whistle 7 is fixedly connected to the end face of the columnar protrusion of the gear 11, the inner side wall of the solar housing 6 is also slidably connected to a rack 12 meshing with the gear 11, and an electric telescopic rod 13 for driving the rack 12 to move is fixedly connected inside, by laying solar power generation panels on the outer wall of the solar housing 6, and installing corresponding transformers and batteries in the solar housing 6, power generation and storage are achieved, and the electric telescopic rod 13 is powered by the battery, and during the migration of birds, when the wind turbine blades 4 rotate, the electric telescopic rod 13 is extended and retracted to achieve the movement of the rack 12, and then the gear 11 meshing with the rack 12 drives the warning whistle 7 to rotate, so that the air outlet of the warning whistle 7 faces the rotation direction of the wind turbine blades 4, so that the warning whistle 7 emits a louder sound, and the sound is used to drive away the birds.

[0026] Working principle: red, green and black pigments are respectively poured into the red tube 2, green tube 8 and black tube 9 through the corresponding feeding tubes 10, so that circular red, green and black warning belts are formed on the wind turbine blades 4. Even if the speed of the wind turbine blades 4 is slow, it can still have a good warning effect. When the speed of the wind turbine blades 4 is slow and there are not many birds, only the red tube 2, green tube 8 and black tube 9 are needed. During the migration of birds, the electric telescopic rod 13 is extended and retracted to realize the movement of the rack 12, and then the gear 11 meshing with the rack 12 drives the warning whistle 7 to rotate, so that the blowing port of the warning whistle 7 faces the rotation direction of the wind turbine blades 4, so that the warning whistle 7 emits a louder sound, and the sound is used to drive away the birds.

[0027] The wiring diagram of the electric telescopic rod 13 and the solar panel in the present invention belongs to the common knowledge in the field, and its working principle is a well-known technology. The model is selected according to the actual use, so the control method and wiring arrangement of the electric telescopic rod 13 and the solar panel are not explained in detail.

[0028] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
