[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5 As shown, a municipal engineering drainage structure includes a mounting shell 1. The bottom and outer wall of the mounting shell 1 are provided with multiple rows of drainage holes 2. A filter mechanism 3 is installed on the mounting shell 1. The filter mechanism 3 includes a slot 303. The top side of the mounting shell 1 is provided with a slot 303. A filter screen 308 is slidably connected to one end of the mounting shell 1. A cover plate 301 is engaged with the top of the mounting shell 1 through the slot 303. The bottom of the cover plate 301 is connected to the top of the filter screen 308. An inlet 305 is provided between one side of the filter screen 308 and the bottom of the cover plate 301.

[0023] As a technical optimization of this utility model, the mounting shell 1 has a "7" shaped structure. A sink 304 is provided at the top edge of the mounting shell 1. The sink 304 is connected to the top of the slot 303. The cover plate 301 is engaged with the inner side of the sink 304, which facilitates the sewage to enter the filter screen 308 for filtration. After filtration, the sewage is discharged, and the cover plate 301 is closed tightly and will not loosen.

[0024] As a technical optimization of this utility model, a baffle 307 is installed on the top of one side of the filter screen 308. The baffle 307 has a right-angled triangular cross-section. By installing the baffle 307, it is easy for external sewage and debris to enter the interior of the filter screen 308, while the debris inside the filter screen 308 is not easy to be discharged, thus playing a blocking role.

[0025] As a technical optimization of this utility model, a plurality of equally spaced crossbars 306 are installed on the inner side of the filter screen 308. The crossbars 306 have a triangular cross-section. The installation of the crossbars 306 helps to protect the center of the filter screen 308, making it difficult for internal debris to flow back, and at the same time, it can wrap around and trap hair.

[0026] As a technical optimization of this utility model, handles 302 are respectively installed at both ends of the top of the cover plate 301. The handles 302 are frame-shaped structures. The installation of the handles 302 facilitates the holding of the cover plate 301 and makes it easy to pull out the filter screen 308.

[0027] As a technical optimization of this utility model, the bottom ends of the two handles 302 are respectively fixedly connected to the fixed shafts 310. The handles 302 are rotatably connected to the top center line of the cover plate 301 through the fixed shafts 310. The installation of the fixed shafts 310 facilitates the rotation of the handles 302 and the top of the cover plate 301, and makes it easy to cover and store the handles 302 when not in use.

[0028] As a technical optimization of this utility model, a torsion spring 311 is connected between the fixed shaft 310 and the inside of the cover plate 301. The fixed shaft 310 is rotatably connected to the inside of the cover plate 301 through the torsion spring 311. The installation of the torsion spring 311 facilitates the driving of the fixed shaft 310, so that the handle 302 is always kept in the retracted state.

[0029] As a technical optimization of this utility model, a rubber sleeve 4 is fitted and connected to one side of the top of the mounting shell 1. The rubber sleeve 4 has a frame structure. The installation of the rubber sleeve 4 facilitates a stable connection between the mounting shell 1 and the road, provides good sealing, and makes the drainage effect smoother.

[0030] As a technical optimization of this utility model, two grooves 309 are respectively provided at the center of both ends of the top side of the cover plate 301. The grooves 309 are located on one side of the two handles 302. The opening of the grooves 309 facilitates the rotation and unfolding of the handles 302.

[0031] In use, the mounting shell 1 is first installed on the roadside with its top exposed and one side of the top perpendicular to the road surface. The bottom of the mounting shell 1 is connected to an underground pipe via a conduit. During installation, the mounting shell 1 fits snugly against the roadside with the help of the rubber sleeve 4. Then, the handle 302 is turned to lift the cover plate 301 and filter screen 308, inserting the filter screen 308 into the slot 303 until the cover plate 301 and the recess 304 on the mounting shell 1 are securely engaged. The external force is then removed, and the handle 302 is rotated and retracted under the torque of the torsion spring 311. Rainwater or sewage from the road surface enters the filter screen 308 through the drain hole 2 on the exposed side of the mounting shell 1, filtering and storing debris. The filtered sewage flows down into the underground pipe for transport. When debris accumulates and clogs the filter screen 308, the handle 302 is pulled out to remove the cover plate 301 and filter screen 308, thus cleaning the debris.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
