[0052] In this embodiment, please refer to Figure 3-Figure 5 The shape of the baffle body 122 is consistent with the shape of the manhole 110, and the baffle is installed in the second clamping groove 111; a plurality of first through holes 121 are provided on the baffle body 122.

[0053] Please refer to Figure 3-Figure 5 The shape of the first through hole 121 can be arc, circular, sector-shaped, rectangular, etc., and its shape can be selected according to actual needs.

[0054] Optionally, the plurality of first through holes 121 are arranged at equal angles along the midpoint of the baffle body 122 .

[0059] It is understandable that, in this embodiment, after the filter element 130 is engaged with the first engaging groove 1211, the clamping element 123 is engaged with the first engaging groove 1211, and then the clamping element is connected and fixed to the first engaging groove 1211. Then, the filter element 130 and the clamping element 123 are sequentially mounted and fixed to the baffle body 122. When the tank body 010 is filled with liquid, the liquid passes through the first through hole 121, the filter element 130, the second through hole 1231 and the manhole 110 in sequence and then enters the cavity 011 inside the tank body 010.

[0060] It is worth mentioning that, in an optional embodiment, the number of the filter elements 130 is consistent with the number of the clamping elements 123 and inconsistent with the number of the first through holes 121.

[0063] In this embodiment, the cover structure 140 includes a movably connected base 141 and a cover body 142. The base 141 is provided with a through cavity, one end of the base 141 is fixedly connected to the tank body 010 through a fixing member, and the through cavity is arranged opposite to the manhole 110.

[0064] In this embodiment, please refer to Figure 1 The cover structure 140 includes a connecting rod 143. The outer wall of the base 141 is symmetrically provided with a first fixing member 1411 and a second fixing member 1412. The connecting rod 143 is curved, and the cover body 142 is fixed on the connecting rod 143; one end of the connecting rod 143 is movably connected to the first fixing member 1411 on the base 141 through a movable member, and the other end of the connecting rod 143 is locked with the second fixing member 1412 of the base 141 through a locking pin or the like.

[0065] The working principle of the manhole structure 100 proposed in this embodiment is:

[0066] When the liquid in the tank body 010 shakes and generates impact, the shaking liquid first impacts the buffer plate structure 120 , and then mitigates the impact of the liquid inside the tank body 010 on the cover structure 140 , thereby preventing the liquid in the tank from leaking from the manhole 110 .

[0067] When the staff needs to enter the tank body 010 for maintenance, the staff can lift the buffer plate structure 120 as a whole by the handle; after the maintenance is completed, the baffle body 122 can be lowered to the second clamping groove 111 on the edge of the manhole 110.

[0068] When filling the tank body 010 with liquid, there is no need to lift the buffer plate structure 120, and filling can be done directly at the manhole 110. The buffer plate structure 120 with multiple first through holes 121 can prevent high impact force during filling and can also play a filtering role.

[0069] In summary, the manhole structure 100 proposed in the utility model, by setting a buffer plate structure 120 with multiple first through holes 121 at the manhole 110, when the liquid in the tank body 010 shakes and impacts, the buffer plate structure 120 blocks the shaking liquid from impacting the cover structure 140, and alleviates the impact of the liquid inside the tank body 010 on the cover structure 140, thereby preventing the liquid in the tank from leaking from the manhole 110; at the same time, when the tank body 010 is filled with liquid, the buffer plate structure 120 with multiple first through holes 121 can prevent high impact force during filling and can also play a filtering role.
