[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] As attached Figure 2 and attached Figure 4 As shown, an intelligent manhole cover displacement monitoring device based on the Internet of Things includes a manhole cover base 1 and a manhole cover 4. Multiple sets of positioning rods 13 are installed on the lower edge of the manhole cover 4. Multiple sets of insertion holes 15 are provided at the bottom of the manhole cover base 1 to cooperate with the insertion of the positioning rods 13. Inserting the positioning rods 13 into the insertion holes 15 prevents the manhole cover 4 from rotating in the manhole cover base 1 and ensures the stability of the manhole cover 4.

[0025] As attached Figure 1 and attached Figure 2 As shown, the bottom inner side of the manhole cover base 1 is provided with multiple sets of installation cavities 5. Pressure sensors 6 are installed inside the installation cavities 5. The pressure sensors 6 are connected to wires 20, which are connected to an external control terminal. The wires 20 supply power to the pressure sensors 6 and transmit data. Pressure blocks 7 slide through the upper side wall of the installation cavity 5. The manhole cover 4 is placed inside the manhole cover base 1 and presses against the multiple sets of pressure blocks 7. The multiple sets of pressure sensors 6 detect pressure and determine that the manhole cover 4 is installed normally.

[0026] An annular limiting plate 3 is installed on the top of the manhole cover base 1. An alarm light 9 connected to a pressure sensor 6 is installed inside the annular limiting plate 3. Multiple mounting slots 8 are provided on the upper side of the annular limiting plate 3. The alarm light 9 is installed inside the mounting slot 8. A transparent acrylic plate 10 is installed on the outside of the slot opening of the mounting slot 8. The transparent acrylic plate 10 protects the alarm light 9 and is light-transmitting. When the manhole cover 4 is tilted or lost, if one or more pressure sensors 6 cannot detect the pressure, the data is transmitted to the control terminal to prompt the staff about the location and status of the manhole cover 4, so that the manhole cover can be repaired in time. At the same time, the alarm light 9 is lit and flashes to warn passing vehicles and pedestrians and prevent damage to vehicles and pedestrians.

[0027] The lower end of the manhole cover base 1 is connected to a positioning tube 2, which is installed in the road surface borehole to position the manhole cover base 1. The side wall of the installation cavity 5 is provided with a drain outlet 21, one end of which penetrates the inner wall of the positioning tube 2. Rainwater from the road surface enters the installation cavity 5 and is discharged through the drain outlet 21 into the positioning tube 2 and then into the urban sewer system, preventing water accumulation in the installation cavity 5 from damaging the pressure sensor 6.

[0028] Example 2

[0029] Based on the previous embodiment, the manhole cover 4 is not equipped with a lifting handle. To facilitate the removal of the manhole cover 4 from the manhole cover base 1, as shown in the attached... Figure 3 and attached Figure 4 As shown, the manhole cover 4 has multiple interconnected sliding cavities 11 inside. A movable frame 12 moves vertically within each sliding cavity 11. The bottom of each sliding cavity 11 has a through hole 14 through which a positioning rod 13 slides. The top of the positioning rod 13 slides into the sliding cavity 11 and connects to the lower side of the movable frame 12. A storage groove 16 is located at the center of the manhole cover 4. A threaded sleeve 17 passes through the bottom of the storage groove 16. A threaded shaft 18 passes through the inside of the threaded sleeve 17 and is connected by threads. The lower end of the threaded shaft 18 is rotatably connected to the middle of the movable frame 12. A screwing block 19 is installed on the upper end of the shaft 18. The screwing block 19 is stored inside the storage groove 16. A cross-shaped slot is provided on the upper side of the screwing block 19. A cross-shaped plug with a screwdriver-like structure is inserted into the cross-shaped slot on the upper side of the screwing block 19. Rotating the cross-shaped plug causes the screwing block 19 and the threaded shaft 18 to rotate. The threaded shaft 18 moves upward from the threaded sleeve 17. The screwing block 19 is taken out from the storage groove 16. The threaded shaft 18 drives the moving frame 12 to move upward. The moving frame 12 drives the positioning plug 13 to be pulled out from the plug hole 15. Holding the screwing block 19 can drive the manhole cover 4 to move upward and take the manhole cover 4 out of the manhole cover base 1.
