[0029] The outer side of the anti-falling net plate 5 is connected with a plurality of support rods 6 at equal angles. The support rods 6 at the outer side of the anti-falling net plate 5 are placed on the top of the support block 4 to facilitate the placement of the anti-falling net plate 5. The top of the anti-falling net plate 5 is provided with an anti-falling net 7. An operating ring 8 is installed on the outside of the anti-falling net 7. A clamping block 9 is installed on the top of the support rod 6. The clamping block 9 is clamped in the mesh of the anti-falling net 7 to facilitate the limiting of the anti-falling net 7. A limiting piece 10 is installed on the top of the clamping block 9;

[0030] A snap-in hole 11 is provided at the bottom of the support block 4, a snap-in rod 12 is installed at the bottom of the support rod 6, a limiting hole 13 is provided in the middle of the snap-in rod 12, a sliding long hole 14 is provided at the bottom of the support rod 6, a sliding long rod 15 is installed inside the sliding long hole 14, a sliding tube 16 is slidably installed outside the sliding long rod 15, a connecting plate 17 is installed at the bottom of the sliding tube 16, the length of the sliding long rod 15 is four times the length of the sliding tube 16, the top of the connecting plate 17 is in sliding contact with the bottom of the support rod 6, so as to drive the connecting plate 17 to move, a limiting rod 18 is installed at the bottom of the connecting plate 17, and the outside of the limiting rod 18 is wrapped with an anti-slip ring 19, and the snap-in rod 12 is snapped into the support block 4, one end of the limiting rod 18 is clamped in the limiting hole 13 at the position corresponding to the anti-slip ring 19, which is convenient for limiting the clamping rod 12. A connecting long hole 20 is opened on the top of the connecting plate 17, and a positioning rod 21 is installed on one end surface of the support block 4. The positioning rod 21 is placed in the middle position of the connecting long hole 20. The diameter of the positioning rod 21 is equal to the width of the connecting long hole 20, which is convenient for the positioning rod 21 to pass through the middle of the connecting long hole 20. A rotating stopper 22 is rotatably clamped on the outside of the positioning rod 21. The length of the connecting long hole 20 is twice the length of the rotating stopper 22. The rotating stopper 22 is in rotational contact with the outer end surface of the connecting plate 17, which is convenient for limiting the connecting plate 17.

[0031] The working principle and use process of the utility model are as follows: the embedded base 3 of the manhole cover is embedded in the ground, the connecting plate 17 at the bottom of the supporting rod 6 of the anti-falling net plate 5 is slid toward the middle of the anti-falling net plate 5, and then the supporting rod 6 of the anti-falling net plate 5 is placed on the top of the supporting block 4, so that the snap-in rod 12 is snapped into the inside of the snap-in hole 11, and then the rotating block 22 is rotated to the horizontal position to align with the connecting long hole 20, and then the connecting plate 17 is pushed to make the sliding tube 16 move along the sliding long rod 15, so that the limiting rod 18 is snapped into the inside of the limiting hole 13 to limit the snap-in rod 12;

[0032] When the connecting plate 17 moves, one end of the positioning rod 21 and the rotating block 22 pass through the connecting long hole 20, and finally the rotating block 22 is rotated downward to make the rotating block 22 rotate and fit with the outer end surface of the connecting plate 17, so as to limit the connecting plate 17, and by placing the supporting rod 6 of the anti-falling net plate 5 on the top of the supporting block 4, the clamping rod 12 is clamped with the clamping hole 11, and then the clamping rod 12 is limited by the limiting rod 18, and the rotating block 22 limits the connecting plate 17, so as to achieve double limiting, so that the connection position is more stable, and the anti-falling net plate 5 will not fall off due to the vibration of the manhole cover;

[0033] Finally, place the anti-falling net 7 on the top of the anti-falling net plate 5, with the operating ring 8 facing upward, and pass the top of the clamping block 9 and the limiting piece 10 through the mesh of the anti-falling net 7;

[0034] When the manhole cover is opened or damaged, the anti-falling net 7 inside the manhole cover can collect impurities such as fallen leaves, and the anti-falling net plate 5 can block heavier objects to prevent impurities from passing through the manhole cover and entering the sewer. At the same time, the anti-falling net plate 5 can also prevent pedestrians from falling into it at night, thereby improving the safety of the manhole cover. The surface pattern of the artistic cover plate 2 can also play a beautifying effect.

[0035] When cleaning the fallen leaves and impurities on the surface of the anti-falling net 7, simply pull the operating ring 8 on the top of the anti-falling net 7 upwards to remove the anti-falling net 7, thereby taking out the fallen leaves and impurities for cleaning;

[0036] When it is necessary to remove the anti-falling net plate 5 for operation, first remove the anti-falling net 7, then rotate the rotating block 22 to align with the connecting long hole 20, then pull the connecting plate 17 to separate the limiting rod 18 from the limiting hole 13, and finally pull the anti-falling net plate 5 upward.

[0037] Finally, it should be noted that the above description is only a preferred example of the present utility model and is not intended to limit the present utility model. Although the present utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
