However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0018] like Figure 1-Figure 8 An Internet of Things device for detecting the status of a municipal public manhole cover shown in the figure comprises a manhole body 1 and a manhole cover 2, wherein the end of the manhole body 1 is connected to the manhole cover 2 via a rotating shaft, a fixing frame 3 is fixedly installed on the inner wall of the manhole body 1, a mounting groove 4 is provided on the surface of the fixing frame 3, a cylinder 5 is movably arranged inside the mounting groove 4, and the bottom end of the cylinder 5 is connected to the inner wall of the mounting groove 4 via a rotating shaft, a positioning frame 6 is fixedly arranged on the surface of the manhole cover 2, and the output end of the cylinder 5 is connected to the positioning frame 6 via a rotating shaft, so that the manhole cover 2 can be opened and closed pneumatically, and the degree of automation is high, a first outer frame 7 and a second outer frame 8 are fixedly arranged on the surface of the manhole cover 2, the second outer frame 8 is fixedly connected to the top of the first outer frame 7, and the positioning frame 6 is arranged between the first outer frame 7 and the second outer frame 8. In the middle part of the second outer frame 8, an arc-shaped opening 10 is opened at the top of the second outer frame 8, and a sensor body 11 is installed inside the arc-shaped opening 10. A squeezing mechanism 13 is arranged inside the first outer frame 7, and a clamping mechanism 14 is arranged inside the second outer frame 8. The squeezing mechanism 13 cooperates with the clamping mechanism 14. Through the cooperation between the squeezing mechanism 13 and the clamping mechanism 14, when the manhole cover 2 is covered on the surface of the well body 1, the clamping mechanism 14 can clamp and fix the sensor body 11, and the sensor body 11 can be stably installed on the surface of the manhole cover 2. When the manhole cover 2 is opened, the clamping mechanism 14 cancels the clamping of the sensor body 11, thereby facilitating the staff to disassemble and assemble the sensor body 11, saving the labor cost of the operator.

[0019] An arc-shaped support plate 25 is provided at the center of the second outer frame 8, and the arc-shaped support plate 25 corresponds to the sensor body 11. The sensor body 11 is placed on the surface of the arc-shaped support plate 25. The sensor body 11 can be directly placed on the arc-shaped support plate 25, and it is very convenient for the staff to take the sensor body 11.

[0020] Four positioning holes 12 are evenly opened on the surface of the sensor body 11, and the clamping mechanism 14 includes two transverse plates 22, which are respectively installed on both sides of the arc-shaped support plate 25. A rotating rod 23 is fixedly installed below the end of the arc-shaped support plate 25, and the end of the transverse plate 22 is movably sleeved on the surface of the rotating rod 23. An L-shaped clamping rod 24 is fixedly set in the middle of the transverse plate 22, and the top of the L-shaped clamping rod 24 is clamped in one of the positioning holes 12. The end of the L-shaped clamping rod 24 is provided with an arc chamfer, which pushes the end on the outer side of the transverse plate 22 upward, and the other end of the transverse plate 22 can be rotated upward with the rotating rod 23 as the center. At this time, the top of the L-shaped clamping rod 24 can be directly inserted into the positioning hole 12 to realize the positioning of the sensor body 11.

[0021] A positioning block 26 is fixedly installed at the middle end of the inner wall of the second outer frame 8, and a second spring 27 is arranged below the positioning block 26. The bottom end of the second spring 27 is connected to an extrusion block 28, and the extrusion block 28 is located above the other end of the cross plate 22. Under the action of the second spring 27 and the extrusion block 28, when no external force is applied to the cross plate 22, the elastic force of the second spring 27 can push the cross plate 22 downward. At this time, the cross plate 22 rotates downward with the rotating rod 23 as the center, so that the L-shaped clamp rod 24 expands outward. At this time, the L-shaped clamp rod 24 has no clamping effect on the sensor body 11.

[0022] The extrusion mechanism 13 includes two push rods 18, which are slidably arranged on both sides of the inner cavity of the first outer frame 7, and a side plate 19 is fixedly installed on the inner side of the push rod 18. A second rack 20 is arranged on the surface of the side plate 19, and a gear 21 is meshed on the surface of the second rack 20. The end of the gear 21 is connected to the first outer frame 7 through a rotating shaft, and a frame block 15 is movably arranged below the gear 21. The frame block 15 is located on the inner side of the side plate 19, and a first rack 17 is arranged on the surface of the frame block 15. The first rack 17 is meshed with the gear 21. A first spring 16 is arranged between the frame block 15 and the manhole cover 2, and a push block 31 is fixedly arranged on the top of the push rod 18. The push block 31 is arranged below the cross plate 22, and the push block 31 is in a straight line with the extrusion block 28. When the frame block 15 is in a straight line, the push block 31 is arranged below the cross plate 22. When the block 15 is pressed downward, the gear 21 rotates counterclockwise under the action of the first rack 17, and because the gear 21 is meshed with the second rack 20, the side plate 19 can drive the top rod 18 to slide upward during the counterclockwise rotation of the gear 21. At this time, the top block 31 has an upward squeezing force on the cross plate 22, and the cross plate 22 will rotate upward with the rotating rod 23 as the center to realize the positioning of the sensor body 11. Since the frame block 15 and the manhole cover 2 are connected by the first spring 16, when no pressure is applied to the frame block 15, the frame block 15 will be ejected by the elastic force of the first spring 16. At this time, the first rack 17 drives the gear 21 to rotate clockwise, so that the side plate 19 can drive the top rod 18 to slide downward, and the top block 31 does not cause squeezing force on the cross plate 22.

[0023] A square hole 9 is formed on the surface of the first outer frame 7 , and the surface of the frame block 15 passes through the square hole 9 , so as to ensure that the frame block 15 can move freely and prevent the frame block 15 from being bound by the first outer frame 7 .

[0024] Protruding blocks 29 are fixedly provided on both sides of the top of the fixing frame 3, and a protruding block 30 is fixedly provided on the top of the protruding block 29, and the protruding block 30 corresponds to the frame block 15, so that when the manhole cover 2 is covered on the top of the well body 1, the protruding block 30 has a squeezing force on the frame block 15, so that the sensor body 11 can be fixed on the surface of the manhole cover 2.

[0025] The sensor body 11 is installed at the center of the manhole cover 2. The sensor body 11 can better detect the manhole cover 2 from all aspects, realize functions such as real-time monitoring, automatic alarm and remote monitoring, and improve management efficiency.

[0026] Working principle: First, the staff places the sensor body 11 on the arc-shaped support plate 25 through the arc-shaped opening 10. When the manhole cover 2 is covered on the manhole body 1, the protrusion 30 has a certain squeezing force on the frame block 15. When the frame block 15 is pressed downward, the gear 21 rotates counterclockwise under the action of the first rack 17, and because the gear 21 is meshed with the second rack 20, the side plate 19 can drive the top rod 18 to slide upward during the counterclockwise rotation of the gear 21. At this time, the top block 31 has an upward squeezing force on the cross plate 22, and the cross plate 22 will rotate upward with the rotating rod 23 as the center. Then, at this time, the top of the L-shaped clamp rod 24 can be directly plugged into the positioning hole 12 to realize the positioning of the sensor body 11, thereby The sensor body 11 can better detect the manhole cover 2 in all aspects, realize functions such as real-time monitoring, automatic alarm and remote monitoring, and improve management efficiency. When the manhole cover 2 is opened, the protrusion 30 does not apply pressure to the frame block 15, and the frame block 15 will be ejected by the elastic force of the first spring 16. At this time, the first rack 17 drives the gear 21 to rotate clockwise, so that the side plate 19 can drive the top rod 18 to slide downward. At the same time, the elastic force of the second spring 27 can push the cross plate 22 downward. At this time, the cross plate 22 rotates downward with the rotating rod 23 as the center, so that the L-shaped clamp rod 24 expands outward. At this time, the L-shaped clamp rod 24 has no clamping effect on the sensor body 11, and the staff can take the sensor body 11 at will.

Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements fall within the scope of the present invention claimed.
