[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0021] The present utility model provides a technical solution: As Figure 1 - Figure 4 shown, in this embodiment, an installation structure of a manhole cover alarm device includes a manhole cover alarm device body 1. An installation cylinder 2 is provided at the lower end of the manhole cover alarm device body 1. An installation base 3 is fixedly connected to the lower end of the installation cylinder 2. A rotating disk 13 is provided in the middle of the upper end of the installation base 3. A plurality of arc-shaped sliding grooves 16 are formed through the upper end of the rotating disk 13. A plurality of sliding frames 7 are slidably connected to the inner wall of the installation base 3. A sliding column 15 is fixedly connected to one side of each of the plurality of sliding frames 7. The outer side walls of the plurality of sliding columns 15 are respectively slidably connected to the inner walls of the plurality of arc-shaped sliding grooves 16. A bevel gear two 12 is fixedly connected to the middle of the upper end of the rotating disk 13. A bevel gear one 11 is meshed with one side of the bevel gear two 12. A rotating shaft 9 is fixedly connected to the inner wall of the bevel gear one 11. By placing the bottom of the installation base 3 on the middle of the back of the manhole cover and then rotating the rotating shaft 9, the bevel gear one 11 drives the bevel gear two 12 to rotate, so that the sliding column 15 slides in the arc-shaped sliding groove 16, and the plurality of sliding frames 7 open, and the rubber strip 8 is stuck in the groove on the back of the manhole cover, realizing the quick installation of the manhole cover alarm device body 1. This structure is simple to operate and improves the installation and disassembly efficiency of the staff. An installation groove is provided in the middle of the back of the manhole cover, and the sliding frame 7 is stuck in the installation groove.

[0022] As Figure 2 and Figure 3 shown, both sides of the outer side wall of the rotating shaft 9 are rotatably connected to fixed frames 10. One end of each of the two fixed frames 10 is fixedly connected to the inner top of the installation cylinder 2. The fixed frames 10 are used to install the rotating shaft 9 in the installation cylinder 2.

[0023] As Figure 2As shown in the figure, a fixing bolt 14 is threadedly connected to one side of the outer side wall of the installation cylinder 2. One end of the fixing bolt 14 is threadedly connected to the lower end of the manhole cover alarm device body 1. Through the fixing bolt 14, the manhole cover alarm device body 1 and the installation structure can be separated, and the installation structure can still be reused when replacing the manhole cover alarm device body 1.

[0024] As Figure 1 - Figure 4 shown in the figure, a limiting frame 4 is fixedly connected to one side of the outer side wall of the installation cylinder 2. A hexagonal limiting groove 20 is formed on one side of the limiting frame 4. One end of the rotating shaft 9 is fixedly connected with a hexagonal rotating rod 5. A hexagonal limiting ring 6 is slidably connected to the outer side wall of the hexagonal rotating rod 5. One side of the outer side wall of the hexagonal limiting ring 6 is slidably clamped with the inner wall of the hexagonal limiting groove 20. By pulling the hexagonal limiting ring 6, when the hexagonal limiting ring 6 completely moves onto the hexagonal rotating rod 5, the rotation of the hexagonal rotating rod 5 is released by the hexagonal limiting groove 20. The cooperation of the hexagonal limiting groove 20, the hexagonal limiting ring 6 and the hexagonal rotating rod 5 can prevent the manhole cover alarm device body 1 from falling off the manhole cover. One side of the inner wall of the hexagonal limiting ring 6 is on the hexagonal rotating rod 5 and the other side is in the hexagonal limiting groove 20.

[0025] As Figure 4 shown in the figure, a top rod 19 is slidably connected to one side of the inner wall of the hexagonal rotating rod 5. The lower end of the top rod 19 is fixedly connected with a return spring 18. One end of the return spring 18 is fixedly connected with one side of the inner wall of the hexagonal rotating rod 5. Through the cooperation of the return spring 18 and the top rod 19, it is prevented that the vehicles on the road surface press the manhole cover for a long time, causing the hexagonal limiting ring 6 to slowly move out of the hexagonal limiting groove 20.

[0026] As Figure 3 shown in the figure, a rotating groove 17 is formed in the middle of the upper end of the installation base 3. The inner wall of the rotating groove 17 is rotatably connected to the lower end of the rotating disc 13. The rotating disc 13 and the installation base 3 are connected into a whole through the rotating groove 17.

[0027] As Figure 1 - Figure 4 shown in the figure, a plurality of rubber strips 8 are fixedly connected to the outer side wall of the sliding frame 7. Through the elasticity of the rubber strips 8 themselves, the manhole cover alarm device body 1 can be installed more stably.

[0028] The present utility model provides an installation structure for a manhole cover alarm device, and the specific working principle is as follows:

[0029] When installing the manhole cover alarm device on the manhole cover, first pull the hexagonal limit ring 6. One side of the hexagonal limit ring 6 presses against the ejector rod 19, and the ejector rod 19 enters the groove of the hexagonal rotating rod 5, releasing the sliding of the hexagonal limit ring 6. When the hexagonal limit ring 6 completely moves onto the hexagonal rotating rod 5, the hexagonal limit groove 20 releases the rotation of the hexagonal rotating rod 5. Place the bottom of the mounting base 3 in the middle of the back of the manhole cover, and then rotate the rotating shaft 9 so that the first bevel gear 11 drives the second bevel gear 12 to rotate. Thus, the sliding column 15 slides in the arc-shaped chute 16, causing the multiple sliding frames 7 to open, and the rubber strip 8 is stuck in the groove on the back of the manhole cover. Then push the hexagonal limit ring 6 and lock one end of the hexagonal limit ring 6 in the hexagonal limit groove 20, thus completing the installation.

[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
