[0002] Chinese patent document CN221609061U discloses a municipal drainage manhole cover, comprising a manhole cylinder, a manhole cover body movably connected to the top of the manhole cylinder, and a disassembly unit inside the manhole cylinder. The disassembly unit includes multiple mounting components fixedly connected inside the manhole cylinder, each mounting component having an mounting groove inside, and a hydraulic rod fixedly connected inside the mounting groove. A filter screen is installed inside the manhole cylinder, and multiple vertical plates are fixedly connected to the bottom of the filter screen, with limit grooves inside each vertical plate. This invention allows users to remove the manhole cover body, then reset the output end using the hydraulic rod, thus releasing the filter screen. Finally, the filter screen can be removed and its surface cleaned. Compared to disassembling the filter screen by rotating bolts, this method is more time-saving and labor-saving, thereby improving the efficiency of cleaning the filter screen.

[0003] The aforementioned municipal drainage manhole cover is prone to clogging the filter screen with debris during use, and it cannot isolate odors from the sewer, causing odors to rise from the drain outlet and causing discomfort to passersby. Therefore, it can be improved. Utility Model Content

[0007] Preferably, the metal main body circular frame has four sets of positioning holes that are equidistantly distributed in a ring. Positioning blocks are inserted into the positioning holes, and trapezoidal circular blocks are fixedly installed on the inner wall of the filter collection cylinder. This not only strengthens the filter collection cylinder but also makes it easy to lift the filter collection cylinder from here.

[0008] Preferably, an annular reinforcing block is fixedly installed at the bottom of the metal main body circular frame, and the annular reinforcing block is fixedly installed to the outer wall of the connecting cylinder, which improves the stability of the metal main body circular frame and the connecting cylinder.

[0009] Preferably, an annular retaining strip is fixedly installed on the outer wall of the connecting cylinder, and an internally threaded connecting cylinder is threadedly sleeved on the outer wall of the connecting cylinder, with one end of the internally threaded connecting cylinder in contact with the annular retaining strip.

[0010] Preferably, the outer wall of the internally threaded connecting cylinder is provided with two or more sets of strip-shaped actuating grooves that are distributed in an annular shape at equal intervals.

[0011] Preferably, the connecting assembly includes a connecting threaded post and a connecting round block. The hollow funnel-shaped rubber has four sets of slots that are evenly distributed in an annular pattern. The inner wall of the internally threaded connecting cylinder has a threaded groove. One end of the connecting threaded post passes through the slot and is threaded into the threaded groove. The other end of the connecting threaded post is fixedly connected to the connecting round block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This municipal drainage filtration mechanism, through the combined use of a metal grid disc, connecting cylinder, annular baffle, internally threaded connecting cylinder, hollow funnel-shaped rubber, connecting threaded column, connecting round block, filter collection cylinder, trapezoidal round block, and positioning insert, can perform preliminary and secondary filtration of discharged water. The multi-stage operation improves the filtration effect, and the shape of the filter collection cylinder makes it less prone to clogging. On the other hand, it can prevent backflow of odors, avoiding discomfort to passersby caused by odors from the drainage outlet. Furthermore, the hollow funnel-shaped rubber is easy to disassemble and replace, enhancing the comfort and practicality of the filtration mechanism. Attached Figure Description

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a municipal drainage filtration mechanism, including a metal main circular frame 1, a filter collection cylinder 8, and an anti-odor structure. A connecting cylinder 3 is fixedly installed at the bottom of the metal main circular frame 1, and a metal grid plate 2 is snapped onto the metal main circular frame 1. The filter collection cylinder 8 is disposed on the metal main circular frame 1 and is located at the bottom of the metal grid plate 2. A positioning block 10 is fixedly installed on the outer wall of the filter collection cylinder 8. The anti-odor structure is disposed on the connecting cylinder 3 and consists of an internally threaded connecting cylinder 5 and a hollow funnel-shaped rubber 6. A connecting component 7 is disposed on the internally threaded connecting cylinder 5 and the hollow funnel-shaped rubber 6.

[0022] The metal main body circular frame 1 has two sets of symmetrical actuation ports on its left and right sides. The metal main body circular frame 1 has four sets of equidistant positioning ports on its ring. Positioning blocks 10 are inserted into the positioning ports. Trapezoidal blocks 9 are fixedly installed on the inner wall of the filter collection cylinder 8. An annular reinforcing block 11 is fixedly installed at the bottom of the metal main body circular frame 1. The annular reinforcing block 11 is fixedly installed on the outer wall of the connecting cylinder 3. An annular baffle 4 is fixedly installed on the outer wall of the connecting cylinder 3. The internally threaded connecting cylinder 5 is threaded onto the outer wall of the connecting cylinder 3. One end of the internally threaded connecting cylinder 5 is in contact with the annular baffle 4. The outer wall of the internally threaded connecting cylinder 5 has two or more sets of equidistant strip actuation grooves on its ring.

[0023] The connecting assembly 7 includes a connecting threaded post 71 and a connecting block 72. The hollow funnel-shaped rubber 6 has four sets of equally spaced annular slots. The inner wall of the internally threaded connecting cylinder 5 has a threaded groove. One end of the connecting threaded post 71 passes through the slot and is threaded into the threaded groove. The other end of the connecting threaded post 71 is fixedly connected to the connecting block 72. During drainage, the metal grid disc 2 automatically filters out larger impurities. Then, after the water passes through the filter collection cylinder 8, smaller impurities are automatically intercepted and filtered. The weight of the water then squeezes the hollow funnel-shaped rubber 6 to open and automatically discharge it. On the one hand, it can perform preliminary and secondary filtration of the discharged water. The multi-stage operation makes the filtration effect better. The shape of the filter collection cylinder 8 makes it less prone to clogging. On the other hand, it can prevent backflow of odors, avoiding discomfort to passersby caused by backflow of odors at the drainage point. The hollow funnel-shaped rubber 6 is easy to disassemble and replace, enhancing the comfort and practicality of the filtration mechanism.

[0024] Working principle: When draining water, the metal grid disc 2 automatically filters out larger debris. Then, after the water passes through the filter collection cylinder 8, smaller debris is automatically intercepted and filtered out. Then, the weight of the water squeezes the hollow funnel-shaped rubber 6 to open and automatically discharge it.

[0025] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
