[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Reference Figures 1-5A wind farm area monitoring device based on the Internet of Things includes a camera 6 and a support frame 3. A second slide rail 23 is bolted to the outer wall of the support frame 3. A sliding ring 21 is sleeved on the outer side of the support frame 3 and slidably connected to the second slide rail 23. The second slide rail 23 guides the sliding ring 21 to prevent it from rotating during movement. Inside the support frame 3 is a pull rope assembly that moves the sliding ring 21 along the second slide rail 23. The pull rope assembly includes a carrier plate 28, which is bolted to the inside of the support frame 3. A first motor is bolted to the bottom of the carrier plate 28. A worm gear 24 is rotatably connected to the upper surface of the carrier plate 28, and one end of the output shaft of the first motor passes through the carrier plate 28 and is fixed to the worm gear 24. A connecting shaft 27 is rotatably connected to one inner wall of the support frame 3, and a worm wheel 26 is keyed to the outer side of the connecting shaft 27. The worm gear 26 meshes with the worm 24. A take-up roller 25 is bolted to the outside of the connecting shaft 27. A rope 17 is wound around the outside of the take-up roller 25. One end of the rope 17 passes through the top of the support frame 3 and is fixed to the sliding ring 21. The first motor drives the worm 24 to rotate. Since the worm 24 meshes with the worm gear 26, the connecting shaft 27 drives the take-up roller 25 to rotate. The take-up roller 25 unwinds the rope 17, thereby driving the sliding ring 21 to move down along the second slide rail 23 to the required position, and thus moving the camera 6 down to the required position for easy maintenance. A fixing frame 19 is bolted to the top outer wall of the support frame 3. A guide roller 18 is rotatably connected to the fixing frame 19, and the rope 17 passes over the top of the guide roller 18. The guide roller 18 can guide the rope 17 to move in the required direction.

[0030] It should be noted that two first slide rails 22 are welded to the outer side of the sliding ring 21, and a slider 2 is slidably connected to the outer side of the two first slide rails 22. The sliding ring 21 is equipped with a power component that drives the slider 2 to move. The power component includes a gear plate 20, which is welded to the top of the slider 2. A support plate 16 is fixed to the top of the sliding ring 21 by bolts. A geared motor is fixed to one side of the support plate 16 by bolts. The geared motor is model RV75-20-Y1.5KW. A gear 15 is rotatably connected to the other side of the support plate 16, and one end of the output shaft of the geared motor passes through the support plate 16 and is fixed to the gear 15. The gear 15 meshes with the teeth on the gear plate 20. The geared motor drives the gear 15 to rotate, thereby causing the gear plate 20 to drive the slider 2 to move along the first slide rail 22, so that the staff can further adjust the position of the camera 6 according to the usage requirements.

[0031] Specifically, a first connecting rod 5 is bolted to one side of the slider 2. A rotating shaft 10 is welded to one end of the first connecting rod 5. A second connecting rod 7 is rotatably connected to the outside of the rotating shaft 10, and the top end of the second connecting rod 7 is fixed to the camera 6. The second connecting rod 7 and the rotating shaft 10 are fixed by a detachable connecting assembly. The connecting assembly includes two first toothed blocks 8, which are respectively welded to one end of the rotating shaft 10. Second toothed blocks 9 are slidably connected to both ends of the rotating shaft 10, and the first toothed blocks 8 mesh with the corresponding second toothed blocks 9. The top of each of the 9 is welded with a fixing plate 14. A bidirectional threaded rod 12 is rotatably connected to the second connecting rod 7, and both ends of the bidirectional threaded rod 12 pass through the second connecting rod 7 and are threadedly connected to the fixing plate 14. When it is necessary to adjust the angle of the camera 6, rotate the bidirectional threaded rod 12 so that the two fixing plates 14 drive the second tooth block 9 connected to them to move outward along the rotation axis 10 respectively. Then, rotate the second connecting rod 7 around the rotation axis 10 to adjust the angle of the camera 6. After the adjustment is completed, reverse the bidirectional threaded rod 12 so that the second tooth block 9 and the first tooth block 8 can be re-engaged.

[0032] In this invention, a guide rod 13 is slidably connected to the fixed plate 14, and the guide rod 13 is fixed to the fixed plate 14. The guide rod 13 guides the sliding of the fixed plate 14. An electric push rod 29 is fixed to the bottom of the carrier plate 28 by bolts. A bracket 30 is fixed to the extended end of the electric push rod 29 by bolts. A sliding ring 21 has a sliding groove 32 and a slot 31, and the slot 31 is connected to the sliding groove 32. The protrusion on the bracket 30 is inserted into the corresponding slot 31. When the sliding ring 21 moves along the second slide rail 23 to the top of the support frame 3, the position of the bracket 30 corresponds to the position of the sliding groove 32, and the electric push rod 29 is activated. When the electric push rod 29 extends, the card holder 30 enters the slide groove 32, and at the same time, the protrusion on the card holder 30 is inserted into the slot 31, thereby fixing the position of the sliding ring 21. The bottom end of the support frame 3 is fixed with a mounting plate 4 by bolts. The mounting plate 4 is used to fix the support frame 3 in the required position. The top end of the support frame 3 is fixed with a protective eave 1 by bolts. The protective eave 1 can protect the top of the device. The bottom of the camera 6 housing is fixed with a wireless communication module 11, and the wireless communication module 11 is electrically connected to the camera 6. The camera 6 transmits the monitoring image to the external device through the wireless communication module 11 to realize the monitoring function of the wind farm area.

[0033] Working principle of this embodiment: When camera 6 needs to be inspected:

[0034] The first motor is started, which drives the worm 24 to rotate. Since the worm 24 meshes with the worm wheel 26, the connecting shaft 27 drives the take-up roller 25 to rotate. The take-up roller 25 unwinds the rope 17, thereby driving the sliding ring 21 to move down along the second slide rail 23 to the required position, and thus moving the camera 6 down to the required position for easy maintenance by the staff.

[0035] When the position of camera 6 needs to be adjusted:

[0036] Start the reduction motor, which drives the gear 15 to rotate, thereby causing the gear plate 20 to move the slider 2 along the first slide rail 22, so that the staff can adjust the position of the camera 6 according to the usage requirements.

[0037] When the angle of camera 6 needs to be adjusted, rotate the bidirectional threaded rod 12 so that the two fixed plates 14 drive the second toothed blocks 9 connected to them to move outward along the rotating shaft 10 respectively. Then rotate the second connecting rod 7 around the rotating shaft 10 to adjust the angle of camera 6. After the adjustment is completed, reverse the bidirectional threaded rod 12 so that the second toothed block 9 and the first toothed block 8 can be re-engaged.

[0038] When the sliding ring 21 moves along the second slide rail 23 to the top of the support frame 3, the position of the card holder 30 corresponds to that of the slide groove 32. When the electric push rod 29 is activated and the electric push rod 29 extends, the card holder 30 enters the slide groove 32. At the same time, the protrusion on the card holder 30 is inserted into the slot 31, thereby fixing the position of the sliding ring 21.

[0039] It should be noted that the geared motor in this application is prior art, consisting of a motor part, a reducer part, auxiliary components and an output shaft, etc. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0040] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.
