[0029] The movable plate 6 is driven upward by the pull ring 7, and the telescopic plate 4 is pulled upward in the connecting plate 3 under the drive of the movable plate 6. During the pulling process, the movable plate 6 will also drive the pull rope 12 to pull the two filter frames 8 upward. The filter frame 8 is folded together with the connecting plate 3 with the cooperation of the hinge 9, and the garbage in the filter net 10 is wrapped between the filter frame 8 and the connecting plate 3, so that the garbage will not be scattered into the sewer. When the movable plate 6 continues to move upward, the folded filter frame 8 will be lifted out of the placement groove 18, so that the garbage sandwiched between the filter frame 8 and the connecting plate 3 can be easily cleaned.

[0030] Reference Figure 2-3 The buffer mechanism includes a plug-in slot 13 and a buffer tube 14. The buffer tube 14 is sleeved inside the plug-in slot 13, and a buffer rod 15 is sleeved inside the buffer tube 14. A pressure plate 16 is fixedly provided at the bottom of the buffer rod 15, and a buffer spring 17 is fixedly provided at the bottom of the pressure plate 16.

[0031] The buffer rod 15 drives the pressure plate 16 to squeeze the buffer spring 17, causing the buffer spring 17 to deform. At the same time, the elastic force of the buffer spring 17 is used to buffer and absorb the impact force brought by the manhole cover body 2, thereby reducing the damage to the manhole cover body 2 caused by the impact.

[0032] Reference Figure 3 The top of the buffer rod 15 is fixedly connected to the manhole cover body 2 , a placement groove 18 is provided through the top of the manhole cover body 2 , and a plurality of drainage grooves 19 are provided through both ends of the placement groove 18 .

[0033] By inserting the buffer tube 14 and the buffer rod 15 into the insertion groove 13, the connection and fixation between the manhole cover body 2 and the manhole cover frame 1 can also be achieved.

[0034] Reference Figure 4 The movable plate 6 is sleeved inside the placement groove 18 , the telescopic plate 4 is fixedly connected to the movable plate 6 , and the length of the telescopic plate 4 is smaller than that of the connecting plate 3 .

[0035] By placing the movable plate 6 in the placement groove 18 and the pull ring 7 being lower than the inner wall height of the placement groove 18, it can be ensured that the pull ring 7 will not be higher than the upper side of the manhole cover body 2 and trip passers-by.

[0036] Referring to 1 , the drainage trough 19 , the manhole cover frame 1 and the manhole cover body 2 are all square structures.

[0037] Reference Figure 3 A limiting block 20 is provided below the filter frame 8, the limiting block 20 is fixedly connected to the inner wall of the manhole cover frame 1, the filter frame 8 abuts against the limiting block 20, and the filter screen 10 is made of nylon.

[0038] The garbage is collected through the filter 10, and the filter 10 is made of nylon, has acid and alkali resistance, good corrosion resistance, and has a certain elasticity. When the filter frame 8 and the connecting plate 3 are folded, the garbage can be better gathered.

[0039] Working principle: When cleaning, the staff pulls the pull ring 7, and the movable plate 6 is driven to move upward through the pull ring 7. The telescopic plate 4 is moved upward in the connecting plate 3 under the drive of the movable plate 6. At the same time, the movable plate 6 will also drive the pull rope 12 to pull the two filter frames 8 upward, and the filter frame 8 and the connecting plate 3 are folded together with the cooperation of the hinge 9, and the garbage in the filter net 10 is wrapped between the filter frame 8 and the connecting plate 3, so that the garbage will not be scattered into the sewer. The movable plate 6 will lift the folded filter frame 8 from the placement groove 18 during the continuous upward movement, so that the garbage sandwiched between the filter frame 8 and the connecting plate 3 can be easily cleaned. After cleaning, repeat the above actions, and then lift the filter frames 8 folded on both sides of the connecting plate 3 from the placement groove 18 and slowly put it in, until the movable plate 6 closes the placement slot 18, the telescopic plate 4 also enters the connecting plate 3, and the pull rope 12 is continuously relaxed to make the filter frame 8 contact with the limit block 20 to carry out daily garbage filtering. There is no need to open the manhole cover body 2, the filter screen 10 can be cleaned separately, so as to achieve the purpose of convenient cleaning, saving time and effort; in daily use, when the vehicle on the road presses on the manhole cover body 2, the buffer rod 15 will squeeze the buffer cylinder 14 with the impact force brought by the manhole cover body 2, and the buffer rod 15 drives the pressure plate 16 to squeeze the buffer spring 17, so that the buffer spring 17 is deformed, and at the same time, the elastic force thereof is used to buffer and absorb the impact force, thereby reducing the damage caused by the impact to the manhole cover body 2 and prolonging the service life of the manhole cover body 2.
