[0028] Further, the mounting rod 11 is used in combination with the adjusting bolt 22, the adjusting rod 23 and the mounting plate 24, and the air bag 5 is combined with the mounting ring 12 into a sealing mechanism. Since the diameters of the well 2 are different due to different constructions, the mounting plate 24 is attached to the inner wall of the well 2 by adjusting the expansion and contraction of the adjusting rod 23, is fixed in the well 2 by using a bolt, is fixed by rotating the adjusting bolt 22 to fix the adjusting rod 23, achieves the effect of mounting the mounting ring 12, and can be used in the well 2 with different diameters.

Figure 1

[0029] ​Further, the damper 14 and the base 13 form an adjusting mechanism, the plug 9 and the second downspout 8 are matched in size, and the arrangement of the plug 9 and the second downspout 8 is consistent, the dampers 14 are uniformly distributed around the drain ring 15, the plug 9 is installed on the bottom plate 10 through bolts, the bottom plate 10 is installed on the base 13 through the support rod 4, when it rains, rainwater is discharged into the shaft 2 through the downspout 7, when the amount of water is small, the rainwater in the shaft 2 is discharged through the drain port 17, the bottom of the drain port 17 is provided with a drain baffle 18, the drain baffle 18 is opened by the weight of the rainwater, and when the rainwater is discharged, the drain baffle 18 is closed by the elastic force of the spring, when the amount of rainwater is too large, the rainwater in the shaft 2 will accumulate, and when the weight of the accumulated rainwater is greater than the elastic force of the damper 14, the base 13 will descend, a gap is formed between the base 13 and the drain ring 15, and water is discharged, so that the water discharge capacity is increased, and due to the descent of the base 13, the bottom plate 10 is driven to descend, so that the plug 9 is separated from the second downspout 8 (as shown in Figure 2 , the water discharge capacity of the well lid 3 is increased, and through the movement of the plug 9, the probability of clogging of the water inlet of the well lid 3 is also reduced.

[0030] Further, the air inlet valve 1402 of the damper 14 is larger than the air outlet valve 1403, because the air inlet valve 1402 is larger than the air outlet valve 1403, the descending speed of the piston 1404 is greater than the ascending speed, the ascending speed of the piston 1404 is slowed down, the ascending of the base 13 is slowed down, and the discharge of the rainwater in the shaft is more thorough.

[0031] Further, the drain ring 15 and the filter screen 6 form a garbage collection and cleaning mechanism, garbage on the road surface will enter the shaft 2 along with the rainwater, and will cause the shaft 2 to be blocked as time accumulates, the bottom of the mounting ring 12 is provided with the filter screen 6, the filter screen 6 can collect the garbage in the shaft 2, and the filter screen 6 can be cleaned by the staff regularly (as shown in Figure 4 , the filter screen 6 can be cleaned or replaced, and the shaft 2 can be maintained.

[0032] Further, the bottom plate 10 has a protection function, because the daily maintenance of some drainage well covers is not done, and the daily aging causes some drainage well covers to be unable to withstand the weight of pedestrians and to collapse, causing accidents, when the pedestrian steps on the well cover 3, the pedestrian will first fall on the bottom plate 10, and the bottom plate 10 will stop descending after descending a certain distance, so as to prevent the pedestrian from falling and causing dangerous accidents.

[0033] Working principle: by adjusting the telescopic adjusting rod 23, the mounting plate 24 is attached to the inner wall of the shaft 2, and is fixed inside the shaft 2 by bolts. Turning the adjusting bolt 22 fixes the adjusting rod 23, achieving the effect of installing the mounting ring 12. After fixing, the air bag 5 is inflated to fill the gap between the mounting ring 12 and the shaft 2, achieving the effect of sealing. When it rains, rainwater is discharged into the shaft 2 through the downspout 7. When the amount of water is small, the rainwater in the shaft 2 is discharged through the drain 17. The bottom of the drain 17 is provided with a drain baffle 18, which is opened by the weight of the rainwater. When the rainwater is discharged, the drain baffle 18 is closed by the elastic force of the spring. When the amount of rainwater is too large, the drain 17 cannot discharge the water in time, and the shaft 2 will accumulate rainwater. When the weight of the accumulated rainwater is greater than the elastic force of the damper 14, the base 13 will descend, forming a gap between the base 13 and the drain ring 15, discharging water and increasing the drainage capacity. Moreover, the descent of the base 13 drives the bottom plate 10 to descend, causing the plug 9 to separate from the second downspout 8 (as shown in Figure 2 ), increasing the drainage capacity of the well lid 3. The movement of the plug 9 also reduces the probability of clogging of the downspout of the well lid 3. The garbage on the road surface will enter the shaft 2 with the rainwater, and will cause the shaft 2 to be clogged over time. A filter screen 6 is arranged at the bottom of the mounting ring 12, which can collect the garbage in the shaft 2. The filter screen 6 can be cleaned regularly by the staff (as shown in Figure 4 ). The bottom plate 10 and the drain ring 15 can be removed by the staff to clean or replace them (as shown in ), facilitating the maintenance of the shaft 2.

[0034] Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can modify the technical solutions described in the foregoing embodiments, or make equivalent replacements to part of the technical features, as long as they are within the spirit and principles of the present application. Any modification, equivalent replacement, improvement, etc. made within the scope of the present application shall be included in the protection scope of the present application.
