The base 2 is placed at the monitoring position; the rotation drive unit is started to drive the housing 1 to rotate, and the monitoring angle of the smart camera 5 is adjusted; the lifting frame 3 moves up, pushing the rotating plate 4 to rotate upward in the slot 6, and then driving the smart camera 5 to rotate upward; the lifting frame 3 moves down, and the rotating plate 4 is pushed downward by the first spring 9, driving the smart camera 5 to rotate downward; the indoor space is photographed by the smart camera 5, and the monitoring picture is transmitted to the cloud platform for processing via the network.

[0038] At the same time, multiple magnetic units are sequentially arranged on the lifting frame 3 and located at both ends of the roller 11. The lifting unit is arranged at the bottom of the shell 1. The lifting frame 3 is arranged on the lifting unit. The pushing component 13 is arranged inside the lifting frame 3.

The two ends of the two second springs 16 are respectively connected to the bottom of the rotating metal block 15 and the two sides of the support block 14. The electromagnetic plate 12 is arranged below the rotating plate 4. The pushing component 13 is a self-locking electric push rod; the electromagnetic plate 12 is energized to generate magnetic force, and then when the rotating plate 4 is adjusted to a suitable angle, the pushing component 13 is started, driving the supporting block 14 to move upward, so that the rotating metal block 15 is close to the electromagnetic plate 12, thereby adsorbing each other to complete the fixation of the rotating plate 4, and avoiding the rotating plate 4 from shaking when the smart camera 5 is shooting. At the same time, when the rotating metal block 15 moves up and fits the electromagnetic plate 12, the rotating metal block 15 can rotate on the supporting block 14, and then adapt to different inclination angles of the rotating plate 4. When the magnetic attraction limit ends, the electromagnetic plate 12 is powered off, and the pushing component 13 drives the rotating metal block 15 to move downward.

[0039] Then, the lifting frame 3 has a slide groove 25, and the two sliders 24 are slidably connected to the slide groove 25.

The two connecting plates 22 are cross-arranged and are both sleeved on the outside of the cross shaft 23. The cross shaft 23 makes the two connecting plates 22 cross-arranged so as to rotate inward and outward, thereby driving the lifting frame 3 to move up and down. The support plate 17 supports the entire lifting unit. The first driving component 18 is a self-locking motor; when the first driving component 18 is started, it drives the two symmetrical screw rods 20 to rotate through the connection of the connecting shaft 19, and cooperates with the threaded block 21 to drive the two connecting plates 22 to rotate on the cross shaft 23 and retract inward. At the same time, the end of the connecting plate 22 away from the threaded block 21 drives the slider 24 to slide in the slide groove 25, thereby moving the lifting frame 3 upward, and vice versa.

[0040] Again, the second driving component 26 is arranged inside the base 2, and the output end of the second driving component 26 is fixedly connected to the first gear 27, the first gear 27 and the second gear 28 are meshed with each other, one end of the driving shaft 29 is fixedly connected to the bottom of the outer shell 1, the other end of the driving shaft 29 passes through the base 2 and is rotatably connected to the inner bottom wall of the base 2, the second gear 28 is sleeved on the outside of the driving shaft 29, one end of the two stabilizing slide bars 30 are fixedly connected to the bottom of the outer shell 1, the base 2 has an annular groove 31, and the other ends of the two stabilizing slide bars 30 are slidably connected to the annular groove 31.

Therefore, by rotating the two smart cameras 5 and arranging the smart cameras 5 on both sides of the housing 1, the front and rear sides of the housing 1 can be monitored and photographed at the same time, and the up and down rotation of the smart cameras 5 can greatly improve the monitoring range.

[0042] Finally, the height adjustment unit is sequentially arranged on the base 2; the adjustment rod 36 has a plurality of slots 40, the base 2 has a groove 41, the adjustment rod 36 is slidably connected to the base 2, the clamping rod 37 is located inside the groove 41, one end of the clamping rod 37 passes through the groove 41 and is mutually adapted with the clamping groove 40, the other end of the clamping rod 37 is fixedly connected to the handle 39, the two ends of the third spring 38 are respectively movably connected to the handle 39 and the inner wall of the groove 41, and the third spring 38 is sleeved on the outside of the clamping rod 37. When it is necessary to adjust the overall height of the monitoring device, the clamping rod 37 is pulled out through the handle 39, and then the adjustment rod 36 is pulled out from the base 2, at this time, the handle 39 is released, and the third spring 38 rebounds, driving the clamping rod 37 to enter the slot 40, so as to limit and fix the adjustment rod 36.

[0043] When using a cloud platform-based monitoring device of this embodiment, the base 2 is placed in the monitoring position; the second driving component 26 is started, driving the first gear 27 to rotate, and by meshing with the second gear 28, driving the driving shaft 29 to rotate, so that the housing 1 and the two smart cameras 5 rotate, and the monitoring angle of the smart camera 5 is adjusted; the first driving component 18 is started, and through the connection of the connecting shaft 19, the two symmetrical screws 20 are driven to rotate, and cooperate with the threaded block 21 to drive the two connecting plates 22 to shrink and rotate inward, and at the same time, the end of the connecting plate 22 away from the threaded block 21 drives the slider 24 to slide in the slide groove 25, thereby causing the lifting frame 3 to move upward, driving the roller 11 to move upward, and then the roller 11 contacts and rotates with the rotating plate 4, pushing the rotating plate 4 to rotate upward; driving the smart camera 5 to rotate upward; when the lifting frame 3 When moving downward, the rotating plate 4 is pushed downward by the rebounded first spring 9, driving the smart camera 5 to rotate downward; after adjusting to a suitable angle, the pushing component 13 is started, driving the supporting block 14 to move upward, so that the rotating metal block 15 is close to the electromagnetic plate 12, thereby adsorbing each other to complete the fixation of the rotating plate 4, and preventing the rotating plate 4 from shaking when the smart camera 5 is shooting. At the same time, when the rotating metal block 15 moves up and fits the electromagnetic plate 12, the rotating metal block 15 can rotate on the supporting block 14, and then adapt to different inclination angles of the rotating plate 4. When the magnetic limit is completed, the electromagnetic plate 12 is powered off, and the pushing component 13 drives the rotating metal block 15 to move downward. At this time, the second spring 16 rebounds, driving the supporting block 14 to reset, so as to continue magnetic attraction next time; at this time, the indoor is photographed by the smart camera 5, and the monitoring picture is transmitted to the cloud platform for processing via the network;

[0044] Through the above-mentioned structural setting, two of the smart cameras 5 are installed on the monitoring equipment, which can simultaneously shoot in two directions, and can simultaneously adjust the two smart cameras 5 to move up and down and rotate, which greatly improves the indoor monitoring range.
