Description

Technical Field

[0001] The utility model relates to the technical field of drainage wells, in particular to a sewer drainage well cover. Background Art

[0002] A sewer is a type of urban public facility, referring to the pipes through which buildings discharge sewage and rainwater; it also refers to the underground passages through which cities, factories or villages discharge sewage and rainwater. A manhole cover is provided on the surface of the drainage well, which is used to filter larger garbage and does not affect normal traffic on the ground.

[0003] Traditional manhole covers are generally directly set as steel covers, and a filter is set at the bottom of the steel cover to filter silt and garbage. However, the filter of the traditional manhole cover is prone to clogging after filtering garbage, so it needs to be cleaned frequently. Moreover, the traditional filter is generally a horizontal structure, and the garbage it can filter is limited. A small amount of garbage will cause it to clog, which is inconvenient for actual use. Utility Model Content

[0004] The purpose of the utility model is to provide a sewer drainage manhole cover, which solves the problem that the filter screen matched with the manhole cover is prone to clogging after filtering garbage, thereby requiring frequent cleaning, and traditional filter screens are generally horizontal structures, and the amount of garbage filtered is limited. A small amount of garbage will cause it to clog, which is inconvenient for actual use.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A sewer drain manhole cover includes a connecting tube, a convex edge is provided on the top of the connecting tube, a fixing ring is provided inside the connecting tube, a filter cartridge is fixedly installed on the top of the fixing ring, a filter plate is provided on the top of the filter cartridge, four connecting rods are fixedly installed on the bottom of the filter plate, connecting rings are fixedly installed on the bottom of the four connecting rods, and four support rods are fixedly installed inside the connecting tube.

[0007] Preferably, the inner wall of the connecting tube is provided with four slideways, four vertical rods are fixedly mounted on the top of the fixing ring, and rollers are evenly provided on the side walls of the four vertical rods, and the rollers are arranged inside the slideways.

[0008] Preferably, the surface of the vertical rod is evenly provided with insertion holes, the surface of the convex edge is provided with grooves, and an insertion rod is movably inserted into the interior of the groove, and the size of the insertion rod is adapted to the insertion hole.

[0009] Preferably, the bottom of the filter cartridge is set to be an opening, the top and side of the filter cartridge are set to be a mesh structure, and the side wall of the filter cartridge is provided with four reinforcing ribs.

[0010] Preferably, the inner wall of the connecting ring contacts the filter cartridge, the outer wall of the connecting ring contacts the inner wall of the connecting cartridge, and the outer wall of the connecting ring is provided with a notch that matches the size of the vertical rod.

[0011] Preferably, a circular hole for a bolt to pass through is provided on the surface of the convex edge.

[0012] The utility model has at least the following beneficial effects:

[0013] When it rains, rainwater enters through the filter plate and is then filtered from the surface of the filter cartridge, making it easy to intercept impurities and silt on the outside of the filter cartridge. Replacing the traditional filter screen with a filter cartridge can increase the effective filtration area. Even if the filter cartridge is clogged, it starts from the bottom and then slowly moves upwards. Therefore, it is more convenient to use than traditional filter screens. When encountering heavy rainstorms, the entire filter plate, vertical rod and fixed ring can be moved upward simultaneously to make the filter cartridge protrude from the ground. After the filter cartridge protrudes from the ground, the contact area between the filter cartridge and rainwater will increase, further improving the filtration efficiency and reducing the phenomenon of reduced filtration efficiency caused by filter cartridge clogging.

In use, the entire connecting tube 1 is first placed directly on the sewer manhole cover, and the convex edge 3 is used to support the manhole cover. Then the entire fixing ring 9 and the filter cartridge 7 are directly placed on the inside of the connecting tube 1, and the fixing ring 9 is supported by the support rod 2. Finally, the connecting ring 14 is sleeved on the surface of the filter cartridge 7, and the connecting ring 14 is placed on the surface of the fixing ring 9. At this time, the filter plate 12 is just flush with the convex edge 3 under the support of the connecting rod 13. When it rains, The garbage silt is intercepted on the surface of the filter cartridge 7, and the entire filter plate 12 can be directly pulled upward, so that the connecting rod 13 drives the connecting ring 14 to move upward synchronously, and then the garbage and silt are conveniently taken out by using the connecting ring 14, which is convenient for operation and use.

[0029] Furthermore, four slideways 4 are provided on the inner wall of the connecting tube 1, four vertical rods 10 are fixedly installed on the top of the fixing ring 9, and rollers 11 are evenly provided on the side walls of the four vertical rods 10.

[0033] Furthermore, a circular hole for the bolt to pass through is opened on the surface of the convex edge 3. The circular hole provided on the convex edge 3 facilitates the bolt to pass through and fix to the wellhead.

[0034] When the filter is in the water, the filter plate 12 is pulled out of the water filter 7, and the filter plate 12 is pulled out of the water filter 7, so that the filter plate 12 is pulled out of the water filter 7, and the filter plate 12 is pulled out of the water filter 7. When the filter cartridge 7 is pulled out of the ground, the contact area between the filter cartridge 7 and the rainwater will be increased, thereby further improving the filtration efficiency and reducing the phenomenon of reduced filtration efficiency caused by clogging of the filter cartridge 7. The garbage and silt are intercepted on the surface of the connecting ring 14, and the entire filter plate 12 can be directly pulled upward, thereby using the connecting rod 13 to drive the connecting ring 14 to move upward synchronously, thereby facilitating the use of the connecting ring 14 to remove the garbage and silt, making it convenient to operate and use. By providing the slide 4, the vertical rod 10 and the roller 11, it is convenient to remove the entire fixing ring 9 and the filter cartridge 7 from the wellhead, reducing the friction during pulling. By providing the insertion rod 6 and the insertion hole 15, when the filter cartridge 7 needs to be pulled out of the ground for use, the insertion rod 6 can be used to fix it, so that the filter cartridge 7 is kept at a fixed height. The provided connecting ring 14 is sleeved on the surface of the filter cartridge 7, and its outer wall contacts the connecting tube 1, which can effectively remove the internal garbage. The circular hole provided on the convex edge 3 is convenient for the bolt to pass through and fix it to the wellhead.
