[0023] Next, with reference to the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. 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.

[0024] Embodiment

[0025] Please refer to Figures 1 to 6 , which is an embodiment of the present utility model. This embodiment provides a technical solution: a bird-friendly wind farm, including

[0026] Multiple friendly wind turbine generators 1 installed in the site. The friendly wind turbine generator 1 includes a tower 11 fixed on the ground, a wind turbine nacelle 12 installed at the top of the tower 11, multiple blades 13 installed at the front end of the tower 11, an ultrasonic bird repeller 15 and a radar detector 16 installed on the top of the wind turbine nacelle 12. And a loudspeaker 14 is also installed on the front surface of the tower 11. The model of the ultrasonic bird repeller 15 is XKQN-10. During actual operation, the radar detector 16 will sense the birds in the site. When it senses that the birds are flying near the friendly wind turbine generator 1, the ultrasonic bird repeller 15 will emit ultrasonic audio to drive away the nearby birds. At the same time, the sound emitted by the loudspeaker 14 can also be used for further driving away. The technical principle of the radar detector 16 sensing the birds and driving them away through the ultrasonic bird repeller 15 is already a well-known technology fully disclosed in the prior art. For details, reference can be made to the existing patent with the publication number CN212845944U, and no further elaboration will be made here;

[0027] Two cylindrical bases 171 are welded and fixed on the top surface of the wind turbine nacelle 12. And a rotatable mounting seat 17 is rotatably installed on the top surface of the cylindrical base 171. The ultrasonic bird repeller 15 and the radar detector 16 are respectively fixed on the top surfaces of the two rotatable mounting seats 17 by bolts. An adjusting mechanism is also provided between the rotatable mounting seat 17 and the cylindrical base 171, so that the ultrasonic bird repeller 15 and the radar detector 16 can be rotated and adjusted in the installation orientation according to different installation requirements in the later stage, improving the overall flexibility of use.

[0028] Among them, the adjusting mechanism includes two inner sliding grooves 181 opened inside the rotatable mounting base 17. An inner sliding seat 188 is slidably installed in the inner sliding groove 181. Two springs 189 are installed between the inner sliding seat 188 and the inner wall of the inner sliding groove 181. The bottom surface of the inner sliding seat 188 is welded and fixed with a bottom sliding rod 187. A bottom sliding groove 184 corresponding to the bottom sliding rod 187 is opened on the bottom surface of the rotatable mounting base 17. The bottom end of the bottom sliding rod 187 passes through the bottom sliding groove 184 to the bottom of the rotatable mounting base 17 and is welded and fixed with a bottom clamping plate 183. A limiting clamping block 185 is welded and fixed on the inner surface of the bottom clamping plate 183. A plurality of limiting clamping grooves 172 corresponding to the limiting clamping block 185 are opened on the circumferential surface of the cylindrical base 171. The limiting clamping block 185 is inserted into one of the limiting clamping grooves 172 to realize the stable limit of the rotatable mounting base 17 during daily use. Two strip-shaped side notches 173 corresponding to the inner sliding grooves 181 in position are symmetrically opened on the surface of the rotatable mounting base 17. An arc-shaped pull rod 186 is welded and fixed on one side of the inner sliding seat 188. The end of the arc-shaped pull rod 186 passes through the strip-shaped side notch 173 and is rotatably installed with a strip-shaped dial 182 through a rotating shaft. The length of the strip-shaped dial 182 is 1.5 times the width of the strip-shaped side notch 173. In the later stage, when the operator needs to rotate and adjust the installation orientation of the ultrasonic bird repeller 15 or the radar detector 16, only need to pull the strip-shaped dial 182 out of the strip-shaped side notch 173 forcefully, so that the inner sliding seat 188 is laterally displaced and the spring 189 is compressed, so that the bottom sliding rod 187 drives the bottom clamping plate 183 to be laterally displaced, and the limiting clamping block 185 is moved out of the limiting clamping groove 172. At this time, rotate the strip-shaped dial 182 by 90 degrees. Because the length of the strip-shaped dial 182 is 1.5 times the width of the strip-shaped side notch 173, the two ends of the strip-shaped dial 182 can be placed on the edge of the rotatable mounting base 17 at this time, which can prevent the strip-shaped dial 182 and the arc-shaped pull rod 186 from rebounding. At this time, because the limiting clamping block 185 has been moved out of the limiting clamping groove 172, the limit on the rotatable mounting base 17 can be released. Then rotate the rotatable mounting base 17 on the top of the cylindrical base 171 to change the installation orientation of the ultrasonic bird repeller 15 or the radar detector 16. When rotated to the appropriate position, only need to rotate the strip-shaped dial 182 back by 90 degrees, so that the strip-shaped dial 182 no longer lies on the edge of the rotatable mounting base 17, and then release the strip-shaped dial 182, so that the spring 189 can smoothly push the inner sliding seat 188 back, and the bottom clamping plate 183 drives the limiting clamping block 185 to reset. Finally, the limiting clamping block 185 can be inserted into the limiting clamping groove 172 at other positions, and the rotatable mounting base 17 can be limited again, so as to complete the rapid rotation adjustment of the installation orientation of the ultrasonic bird repeller 15 or the radar detector 16.

[0029] Among them, two cylindrical slots are formed on one side of the inner sliding seat 188. One end of the spring 189 is inserted into the cylindrical slot, and the other end of the spring 189 abuts against the inner wall of the inner sliding groove 181. The design of the cylindrical slot enables the spring 189 to be limited to a certain extent, preventing the spring 189 from shifting in the inner sliding groove 181.

[0030] Among them, a through hole is formed through between the inner sliding groove 181 and the strip-shaped side notch 173, and the through hole corresponds to the arc-shaped pull rod 186 for the arc-shaped pull rod 186 to pass through smoothly and slide subsequently.

[0031] Among them, an L-shaped rubber plate 1821 is also adhesively fixed to the inner surface of the strip-shaped dial 182. And a circular positioning protrusion 1822 is integrally provided at the bottom of the L-shaped rubber plate 1821. Both are made of rubber material and will undergo elastic deformation when being squeezed. Four circular positioning grooves 1861 corresponding to the circular positioning protrusion 1822 are uniformly formed on the circumferential surface of the arc-shaped pull rod 186. And the circular positioning protrusion 1822 is embedded into one of the circular positioning grooves 1861. When the strip-shaped dial 182 rotates by 90 degrees subsequently, the circular positioning protrusion 1822 will be squeezed into another circular positioning groove 1861 to realize the auxiliary limit after the rotation of the strip-shaped dial 182.

[0032] Among them, a rotating groove is formed inside the cylindrical base 171, and a rotating seat is rotatably installed in the rotating groove. The top end of the rotating seat extends to the top of the cylindrical base 171 and is fixed to the rotatable mounting seat 17, enabling the rotatable mounting seat 17 to rotate smoothly on the top surface of the cylindrical base 171.

[0033] Among them, a plurality of warning signs 131 are installed on the end surface of each blade 13. The warning signs 131 can be red or black signs, which can play a certain warning role for birds.

[0034] Although the embodiments of the present utility model have been shown and described (see the above detailed description), for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
