Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of 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.
[0030] Referring to Figure 1 , Figure 2 and Figure 3, an embodiment provided by the present utility model: a wind power generation wind direction and wind speed detection device, including a wind turbine 1, a housing 2 is fixedly connected to the top of the wind turbine 1, a damping plate 9 is fixedly connected to the inner wall of the housing 2, a first spring 10 is fixedly connected to one side of the damping plate 9, a second mounting plate 16 is provided at one end of the first spring 10, damping devices 17 are fixedly connected to both sides of the bottom of the second mounting plate 16, a second spring 18 is fixedly connected to the inside of the two damping devices 17, clamping plates 23 are fixedly connected to one side of the two damping devices 17, there are two clamping plates 23, and a first rotating rod 26 is provided between the two clamping plates 23, a bolt 24 is threadedly connected to the middle of the first rotating rod 26, a second rotating rod 27 is rotatably connected to the bottom of the first rotating rod 26, a third rotating rod 28 is rotatably connected to the bottom of the second rotating rod 27, a damping block 20 is fixedly connected to the bottom of the third rotating rod 28, a third spring 22 is fixedly connected to one side of the damping block 20, a limiting rod 21 is slidably connected to the middle of the third spring 22 and the damping block 20, fixing blocks 19 are fixedly connected to both sides of the limiting rod 21, first mounting plates 14 are fixedly connected to the bottom of the two fixing blocks 19, the first mounting plates 14 are fixedly connected to the top of the wind turbine 1, and a detection assembly is provided at the top of the housing 2.
[0031] Since the wind turbine 1 generates vibrations during operation, the damping plate 9 can be limited and fixed by the housing 2. The first spring 10 on one side of the damping plate 9 and the damping rod inside it can dampen the vibrations around the housing 2. The first mounting plate 14 can fix and support the damping devices and the fixing blocks 19. At the same time, the second springs 18 and the damping rods inside the two damping devices can dampen the vibrations in the up and down directions of the device. The fixing blocks 19 on the top of the first mounting plate 14 fix the limiting rod 21. The first rotating rod 26 can drive the second rotating rod 27 to move. The second rotating rod 27 can drive the third rotating rod 28 to move. The third rotating rod 28 drives the damping block 20 to move, and the damping rod can squeeze the third spring 22. At this time, the device can be damped, thereby improving the service life of the wind speed and wind direction detection device.
[0032] Refer to Figure 2 , Figure 3 and Figure 4 , one end of the first spring 10 is fixedly connected to a fixing plate. There are four fixing plates, and all four fixing plates are around the first mounting plate 14. The damping devices are between the first mounting plate 14 and the second mounting plate. A first rotating shaft 25 is rotatably connected to the bottom of the first rotating rod 26, and the first rotating shaft 25 is between the first rotating rod 26 and the second rotating rod 27. A second rotating shaft is rotatably connected to the bottom of the second rotating rod 27, and the second rotating shaft is between the second rotating rod 27 and the third rotating rod 28.
[0033] By squeezing the rotating rod 1 (26), the rotating rod 2 (27) is driven to move by the rotating shaft 1 (25). The rotating rod 2 (27) drives the rotating rod 3 (28) to move by the rotating shaft 2. Four damping plates 9, the first springs 10 on one side of the damping plates 9 and the damping rods inside can dampen all around the housing 2.
[0034] Referring to Figure 1 and Figure 2 , the detection assembly includes a wind vane 3 and a connecting rod 6. The top of the second mounting plate 16 is fixedly connected with the connecting rod 6. The connecting rod 6 is at the inner top of the housing 2. The top of the connecting rod 6 is fixedly connected with a first limiting plate 8. There are two first limiting plates 8. There is a first bearing 11 between the two first limiting plates 8. The middle of the first bearing 11 is fixedly connected with a fixing rod 15. One end of the fixing rod 15 is fixedly connected with a second limiting plate 12. There are two second limiting plates 12. There is a second bearing 13 between the two second limiting plates 12. The middle of the second bearing 13 is fixedly connected with a fan 5. The other end of the fixing rod 15 is fixedly connected with the wind vane 3. Damping rods are arranged inside the first springs 10, the second springs 18 and the third springs 22. The top of the first limiting plate 8 is fixedly connected with a wind speed sensor 4. The wind speed sensor 4 is electrically connected with the fan 5. One side of the wind turbine 1 is rotatably connected with a power generation fan blade 7. The wind turbine 1 is electrically connected with the power generation fan blade 7.
[0035] The connecting rod 6 can be limited by the housing 2. By using the first bearing 11 at the top of the connecting rod 6, the wind vane 3 and the fan 5 can be placed on both sides of the first bearing 11. When the wind blows, the wind vane 3 drives the first bearing 11 to rotate. When the wind vane 3 drives the first bearing 11 to rotate, the fan 5 will rotate facing the wind, making the wind speed measurement result more accurate. It realizes the simultaneous measurement of the wind direction and the wind speed, thus improving the practicability of the device.
[0036] Working principle: When in use, when the wind turbine 1 drives the generator fan blade 7 to rotate, vibrations will be generated. At this time, the shock-absorbing plate inside the housing 2 squeezes the first spring 10. By using the first spring 10 and the damping rod inside it, vibration reduction can be carried out around the inside of the housing 2. The shock absorber and the fixing block 19 can be fixed and supported by the first mounting plate 14. At the same time, the second spring 18 and the damping rod inside the shock absorbers on both sides can carry out vibration reduction in the up and down directions of the device. The limiting rod 21 is fixed by the fixing block 19 at the top of the first mounting plate 14. When vibrating up and down, the second mounting plate 16 is pressed downward. The first rotating rod 26 drives the second rotating rod 27 to move by using the first rotating shaft 25. The second rotating rod 27 drives the third rotating rod 28 to move by using the second rotating shaft. The damping block 20 is driven to move by the third rotating rod 28, and the damping rod can be used to squeeze the third spring 22. At this time, the device can be further vibration-reduced, thereby improving the service life of the wind speed and wind direction detection equipment. By placing the wind vane 3 and the fan 5 on both sides of the first bearing 11, when the wind blows, the wind vane 3 drives the first bearing 11 to rotate. When the wind vane 3 rotates, it also drives the fan 5 to face the wind for detection, making the wind speed measurement result more accurate, realizing the simultaneous measurement of wind direction and wind speed, and thus improving the practicability of the device.
[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
