[0036] Example 1

[0037] Reference Figures 1-8 This is the first embodiment of the present invention, which provides a protective device for wind power testing, including a protective mechanism 100. The protective mechanism 100 protects the test structure 404 in the adjustment mechanism 400. The driving structure 200 is used to move the test structure 404 in the adjustment mechanism 400, and the mounting mechanism 300 is used to fix the driving mechanism 200.

[0038] Specifically, the protective mechanism 100 includes a protective plate 101, a threaded collar 102 at one end of the protective plate 101, and a threaded rod 103 inside the threaded collar 102. The protective plate 101 is arranged with respect to the central axis of the threaded collar 102, and the threaded collar 102 is sleeved on the circumferential sidewall of the threaded rod 103.

[0039] Furthermore, the drive mechanism 200 includes a first servo motor 201, a connecting gear 202 at the output end of the first servo motor 201, and a gear disk 203 on the circumferential sidewall of the connecting gear 202, wherein the tooth blocks on the connecting gear 202 and the tooth blocks on the gear disk 203 mesh with each other.

[0040] Furthermore, the installation mechanism 300 includes a wind turbine tower 301, a fixing rod 302 on the inner wall of the wind turbine tower 301, a sliding rod 303 on the circumferential side wall of the fixing rod 302, a fixing structure 304 on the circumferential side wall of the sliding rod 303, and a limiting groove 305 on the circumferential side wall of the sliding rod 303, wherein the limiting groove 305 is semi-arc-shaped and can effectively limit the installation rod 401;

[0041] Furthermore, the adjustment mechanism 400 includes a mounting rod 401 on the inner wall of the limiting groove 305, a connecting plate 402 at one end of the mounting rod 401, a driving structure 403 at the end of the connecting plate 402, and a test structure 404 at the top of the driving structure 403. The test structure 404 is adjusted in position by the driving structure 403.

[0042] Furthermore, the power generation mechanism 500 includes a power generation fan blade 501 at the top of the wind turbine tower 301, a generator 502 at one end of the power generation fan blade 501, and a battery 503 at the bottom of the generator 502.

[0043] Operation process: When the test structure 404 is affected by severe weather, the mounting rod 401 is first fixed to the wind turbine tower 301 by the fixing structure 304. Then, the drive structure 403 is started to drive the test structure 404 to retract. Then, the first servo motor 201 is started, which drives the connecting gear 202 to rotate. The rotating connecting gear 202 drives the gear disk 203 to rotate. The rotating gear disk 203 can rotate and move the threaded collar 102 fitted on the circumferential side wall of the threaded rod 103. The threaded collar 102 moves up and down while rotating, which can drive the top and bottom threaded collars 102 to move closer to each other. Then, the protective plate 101 moves at an angle. The angle movement can effectively protect the test structure 404, reduce the damage to the test structure 404 caused by sand and gravel blown by strong winds, and also reduce the damage to the test structure 404 caused by hail in severe weather.

[0044] Example 2

[0045] Reference Figures 2-8 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the threaded collar 102 fitted on the threaded rod 103 is rotated by the inclined first helical gear 105 and the second helical gear 204.

[0046] Specifically, the protective mechanism 100 also includes a limiting rod 104 on the circumferential side wall of the threaded rod 103, a first inclined gear 105 at the end of the threaded rod 103, and a receiving block 106 on the circumferential side wall of the threaded collar 102, wherein the protective plate 101 and the threaded collar 102 are connected by the receiving block 106.

[0047] Furthermore, the drive mechanism 200 also includes a second helical gear 204 at the bottom of the gear disk 203, wherein the gear disk 203 is slidably connected to the top of the wind turbine tower 301, and the tooth blocks on the gear disk 203 mesh with the tooth blocks on the first helical gear 105, while the tooth blocks on the first helical gear 105 mesh with the tooth blocks on the second helical gear 204.

[0048] Furthermore, the installation mechanism 300 also includes a fixing block 306 at one end of the limiting groove 305, and a first telescopic spring 307 sleeved on the circumferential side wall of the fixing rod 302, wherein one end of the fixing block 306 is connected to the wind turbine tower 301, and one end of the fixing rod 302 is connected to the wind turbine tower 301.

[0049] Furthermore, the fixing structure 304 includes a pin 304a on the circumferential sidewall of the sliding rod 303, a connecting rod 304b on the sidewall of the pin 304a, and a second telescopic spring 304c sleeved on the circumferential sidewall of the connecting rod 304b. The fixing structure 304 also includes a connecting block 304d at the top of the fixing block 306, a pressing groove 304e on the sidewall of the connecting block 304d, a through hole 304f on the circumferential sidewall of the sliding rod 303, and a slot 304g on the circumferential sidewall of the mounting rod 401.

[0050] The rest of the structure is the same as in Example 1.

[0051] Operation process: When the protective plate 101 needs to be activated to protect the test structure 404, the first servo motor 201 is activated. The first servo motor 201 drives the connecting gear 202 to rotate. The rotating connecting gear 202 drives the gear disk 203 to rotate. The rotating gear disk 203 drives the second helical gear 204 to rotate. The rotating second helical gear 204 drives the first helical gear 105 to rotate. The first helical gear 105 drives the threaded rod 103 to rotate. The rotating threaded rod 103 drives the threaded collar 102 sleeved on the circumferential side wall of the threaded rod 103 to rotate and move. The threaded collar 102 moves up and down while rotating, thereby driving the top and bottom threaded collars 102 to move closer to each other. Then, the protective plate 101 moves at an angle. The angle movement can effectively protect the test structure 404.

[0052] Example 3

[0053] Reference Figures 5-8 This is the third embodiment of the present invention. The difference between this embodiment and the previous embodiments is that the connection stability of the drive structure 403 is improved by using a hinged telescopic rod 403i, so as to prevent the test structure 404 from shaking due to wind and other wind forces during the movement, which would affect the test accuracy.

[0054] Specifically, the drive structure 403 includes a disk 403a at the end of the connecting plate 402, a storage tray 403b at the bottom of the disk 403a, a second servo motor 403c at the top of the storage tray 403b, and a drive gear 403d at the output end of the second servo motor 403c.

[0055] Furthermore, the drive structure 403 also includes a driven gear 403e at the top of the disk 403a, a threaded sleeve 403f at one end of the driven gear 403e, a lead screw 403g inside the threaded sleeve 403f, a fixed post 403h at the top of the disk 403a, and a telescopic rod 403i on the side wall of the fixed post 403h, wherein the driven gear 403e is distributed in a circular array with respect to the midpoint of the drive gear 403d.

[0056] Furthermore, the telescopic rod 403i includes a connecting shaft 403i-1 on the side wall of the fixed column 403h, a fixed cylinder 403i-2 at one end of the connecting shaft 403i-1, a moving rod 403i-3 inside the fixed cylinder 403i-2, a hinge shaft 403i-4 at the end of the moving rod 403i-3, and a triangular piece 403i-5 connected to both ends of the hinge shaft 403i-4, wherein the triangular piece 403i-5 is hollow on both sides and in the middle.

[0057] Furthermore, the test structure 404 includes a working box 404a at the top of the triangular piece 403i-5, a test shaft 404b inside the working box 404a, a wind power tester 404c at the top of the test shaft 404b, a fixed gear 404d at the bottom of the test shaft 404b, and a limiting gear 404e on the circumferential side wall of the fixed gear 404d. The fixed gear 404d and the limiting gear 404e are used to prevent the wind power tester 404c from being damaged due to excessive rotation speed.

[0058] Furthermore, the test structure 404 also includes a pressure sensor 404f on the circumferential side wall of the working box 404a, and a temperature sensor 404g on one side of the working box 404a, through which the temperature and pressure at various heights of the wind turbine tower 301 are detected.

[0059] The rest of the structure is the same as in Example 2.

[0060] Operation process: By starting the second servo motor 403c, the second servo motor 403c drives the drive gear 403d to rotate. The rotating drive gear 403d drives the driven gear 403e to rotate. The rotating driven gear 403e drives the threaded sleeve 403f to rotate. The rotating threaded sleeve 403f drives the lead screw 403g to move within the threaded sleeve 403f, thereby effectively driving the test structure 404 to extend outward or retract inward. Then, the wind force is detected by the wind force tester 404c. When testing the wind speed, the fixed gear 404d and the limiting gear 404e are used to prevent the wind force tester 404c from rotating too fast and being damaged.
