DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example 1

[0027] The preferred embodiment of the sewer manhole cover with a filter assembly provided by the utility model is as follows: Figures 1 to 4 As shown: it includes a manhole cover body 1, a first filter hole 4 is opened on the top of the manhole cover body 1, a first filter screen 3 is fixedly connected to the inner wall of the first filter hole 4, a connecting rod 7 is fixedly connected to the bottom of the manhole cover body 1, a connecting column 5 is movably connected to the outer wall of the connecting rod 7, and a rod hole 6 is opened at one end of the connecting column 5.

[0028] The other end of the connecting column 5 is fixedly connected to the filter frame 2, and a second filter hole 15 is opened at the bottom of the filter frame 2. The inner wall of the second filter hole 15 is fixedly connected to the second filter screen 14, the outer wall of the connecting rod 7 is fixedly connected to the upper connecting piece 9, and the outer wall of the connecting column 5 is fixedly connected to the lower connecting piece 11. During the use of the sewer manhole cover, garbage impurities mixed in rainwater can be filtered and intercepted, thereby preventing garbage impurities on the ground from entering the sewer through rainwater, which can improve the cleanliness of the sewer and facilitate people's subsequent cleaning work, thereby improving the effect of the sewer manhole cover when in use.

[0029] In this embodiment, the aperture of the first filter screen 3 is larger than the aperture of the second filter screen 14, and the second filter screen 14 is located below the first filter screen 3, which can improve the filtering and interception effect of rainwater accumulation.

[0030] Example 2

[0031] Based on Example 1, a preferred embodiment of the sewer manhole cover with a filter assembly provided by the utility model is as follows Figures 1 to 4 As shown: the top of the upper connecting plate 9 and the top of the lower connecting plate 11 are respectively provided with a first threaded hole 10 and a second threaded hole 13, and the inner wall of the first threaded hole 10 and the inner wall of the second threaded hole 13 are both threadedly connected with a threaded rod 12, which can be used to install and disassemble the connection between the connecting rod 7 and the connecting column 5, thereby facilitating the disassembly of the filter frame 2 for cleaning, which is convenient for people to use.

[0032] In this embodiment, the shape and size of the connecting rod 7 match the shape and size of the rod hole 6 , and the connecting rod 7 is snap-connected with the connecting column 5 through the rod hole 6 , which facilitates the connection between the connecting rod 7 and the connecting column 5 .

[0033] Furthermore, one end of the threaded rod 12 is fixedly connected to a handle 8 , and the handle 8 is a round handle, so that the threaded rod 12 can be easily rotated by the handle 8 .

[0034] Furthermore, the number of first filter holes 4 and first filter screens 3 is twenty-two, and each first filter hole 4 and each first filter screen 3 form a group, and the twenty-two groups of first filter holes 4 and first filter screens 3 are arranged in a ring shape on the top of the manhole cover body 1, and the first filter screen 3 is a metal filter screen, which can improve the hardness and wear resistance of the first filter screen 3 during use, thereby increasing its service life.

[0035] In addition, the shape and size of the first threaded hole 10 and the shape and size of the second threaded hole 13 match each other. One end of the threaded rod 12 passes through the top of the upper connecting plate 9 and the top of the lower connecting plate 11 through the first threaded hole 10 and the second threaded hole 13 respectively and extends to the bottom of the lower connecting plate 11, which facilitates the connection of the threaded rod 12 with the upper connecting plate 9 and the lower connecting plate 11.

[0036] During use, when the manhole cover body 1 is in use, rainwater enters the sewer through the first filter hole 4 to drain the road. When the rainwater enters the first filter hole 4, it can first be preliminarily filtered through the first filter screen 3. After the preliminary filtration, the rainwater enters the filter frame 2. The second filter screen 14 in the rainwater manhole cover filter frame 2 is filtered again, so that smaller garbage and impurities mixed in the rainwater can be intercepted and filtered.

[0037] In summary, the sewer manhole cover with a filtering component can filter and intercept garbage impurities mixed in rainwater, thereby preventing garbage impurities on the ground from entering the sewer through rainwater, and can improve the cleanliness of the sewer to facilitate people's subsequent cleaning work, thereby improving the effect of the sewer manhole cover when in use.
