[0023] like Figure 1-2 As shown, a new type of integrated anti-fall manhole cover includes a manhole hoop 1, the outer circumferential surface of the manhole hoop 1 is provided with an installation area 11, the upper end of the installation area 11 is hinged with a manhole cover body 2, the inner wall of the installation area 11 is rotatably connected with a connecting block 3, one end of the connecting block 3 is fixedly connected with a connecting steel ring 4, the inner wall of the connecting steel ring 4 is welded with a warning tripod 5 and a metal anti-fall net 6, and a warning mark 7 is welded on one side of the metal anti-fall net 6.
[0024] When in use, the metal anti-fall net 6 can be opened by connecting the steel ring 4 during maintenance to avoid dismantling and prevent the occurrence of secondary missed installation. If the maintenance period is long and the manhole cover is difficult to restore for a while, the warning tripod 5 and warning sign 7 on the metal anti-fall net 6 can remind passers-by, reduce the possibility of non-construction personnel approaching, and greatly reduce safety hazards;
[0025] Under the connection of the connecting block 3, the connecting steel ring 4 can be rotated on the well hoop 1, and the connecting block 3 is rotatably connected in the installation area 11. When the connecting block 3 is rotated to 120°, one side of the connecting block 3 will be against the inner wall of the installation area 11, thereby realizing automatic limiting. Since the maximum rotation angle of the connecting block 3 is 120°, which is greater than 90°, when the connecting steel ring 4 cooperates with the connecting block 3 to rotate 120° together, the connecting steel ring 4 and the metal anti-fall net 6, the warning tripod 5 and the warning sign 7 can all remain stable and are not easy to close automatically. The warning tripod 5 and the warning sign 7 can also remind passers-by more prominently.
[0026] like Figure 1 As shown, the connection block 3 and the connection steel ring 4 are fixedly connected by bolts 8 .
[0027] When in use, the connecting block 3 and the connecting steel ring 4 are designed to be split, and the two are fixedly connected by bolts 8. When the connecting steel ring 4 and the inner wall welding parts are damaged, the bolts 8 can be unscrewed to facilitate disassembly and replacement.

[0031] During use, when the metal anti-falling net 6 is turned to open, the warning tripod 5 and the warning sign 7 will not be blocked by the grid of the metal anti-falling net 6, thereby making the warning tripod 5 and the warning sign 7 more eye-catching.
[0032] like Figure 2 As shown, the side of the warning tripod 5 away from the metal anti-fall net 6 is coated with red reflective paint, and the side of the warning sign 7 away from the metal anti-fall net 6 is coated with yellow reflective paint.
[0033] When in use, the warning triangle 5 and the warning sign 7 can be more eye-catching at night through the reflective paint and bright color matching.
[0034] In summary, the specific working process of the present scheme is as follows: the connecting block 3 is rotatably connected in the installation area 11. When the connecting block 3 is rotated to 120°, one side of the connecting block 3 will be against the inner wall of the installation area 11, thereby realizing automatic limiting. Since the maximum rotation angle of the connecting block 3 is 120°, which is greater than 90°, when the connecting steel ring 4 cooperates with the connecting block 3 to rotate 120° together, the connecting steel ring 4 and the metal anti-fall net 6, the warning tripod 5 and the warning sign 7 can all remain stable and are not easy to close automatically. The warning tripod 5 and the warning sign 7 can also remind passers-by more conspicuously. The metal anti-fall net 6 is integrated with the well hoop 1. During maintenance, the metal anti-fall net 6 can be rotated and opened by the connecting steel ring 4 to avoid dismantling and prevent the occurrence of secondary omission of installation. If the maintenance period is long and the well cover is difficult to restore for a while, the warning tripod 5 and the warning sign 7 on the metal anti-fall net 6 can remind passers-by, reduce the possibility of non-construction personnel approaching, and greatly reduce safety hazards.
