[0002] In the daily operation of a city, manhole covers are an important component of the urban drainage system, and their design and application directly affect the efficiency and safety of urban drainage. Traditional manhole covers often suffer from problems such as bulky design, inconvenient opening, and susceptibility to theft or damage. These problems not only affect the normal operation of the urban drainage system but also bring many inconveniences to citizens' daily lives. Furthermore, during the drainage process after rain, various debris floating on the road surface can easily enter the sewers, causing blockages over time. In addition, in some crowded areas, personal belongings inevitably fall into the sewers, and the complex internal environment of the sewers makes the retrieval process complicated. Therefore, a new type of urban construction manhole cover needs to be designed. Utility Model Content

[0012] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0013] A manhole cover for urban construction includes a manhole cover mounting frame 1, a manhole cover body 2, and a connecting pin 3. The manhole cover body 2 is connected to the inner top side of the manhole cover mounting frame 1 through the connecting pin 3. A locking pin 4 is provided between the manhole cover mounting frame 1 and the manhole cover body 2.

[0014] The above describes the main structure, fixing relationship, and connection relationship of the manhole cover. (See attached diagram.) Figure 1 and attached Figure 2 .

[0015] The manhole cover mounting frame 1 consists of a ground frame 5 and an underground frame 6. The underground frame 6 is located on the bottom side of the ground frame 5 and is integrally formed with the ground frame 5. The inner side of the ground frame 5 is recessed. The two ends of the ground frame 5 are respectively provided with a manhole cover connecting groove 7 and a manhole cover locking groove 8. One end of the ground frame 5 at the manhole cover connecting groove 7 is provided with a through pin hole 9. One end of the manhole cover body 2 is connected to the manhole cover connecting groove 7 by a connecting pin 3, and the manhole cover body 2 can rotate around the connecting pin 3. The other end of the manhole cover body 2 is embedded in the manhole cover locking groove 8, and the other end of the manhole cover body 2 is fixed in the manhole cover locking groove 8 by a locking pin 4. The inner side wall of the manhole cover locking groove 8 is provided with a locking plate groove 10, and the locking pin 4 is embedded in the locking plate groove 10 and can rotate in the locking plate groove 10.

[0016] The above describes the composition of the manhole cover mounting frame 1 and its corresponding positional relationships, including its main connection relationships with the manhole cover body 2, and corresponding attachments. Figure 3 .

[0017] The manhole cover body 2 consists of a manhole cover plate 11, a bottom parallel convex sliding strip 12, a side end fixing lug 13, a side end connecting lug 14, a bottom triangular mesh 15, and a mesh fixing frame 16. The side end connecting lug 14 and the side end fixing lug 13 are arranged opposite to each other at both ends of the manhole cover plate 11. The manhole cover plate 11 has several sets of drain outlets 17, which are arranged at equal intervals. The bottom parallel convex sliding strip 12 is arranged on the bottom side of the manhole cover plate 11, and the bottom parallel convex sliding strip 12 is arranged parallel to each other at the intervals of the drain outlets. The manhole cover plate 11, the bottom parallel convex sliding strip 12, the side end fixing lug 13, and the side end connecting lug 14 are integrally fixed. The bottom triangular mesh 15 is arranged in three sets side by side, and the center plate... The bottom triangular mesh 15 has a depth and height on both sides of the plate. The mesh fixing frame 16 is fixed on the side of the bottom triangular mesh 15. The mesh fixing frame 16 has a connecting groove 18. The bottom parallel convex slide strip 12 can be slidably embedded in the connecting groove 18 on the mesh fixing frame 16. The side of the side fixing ear 13 has a locking plate groove 10. The side fixing ear 13 is embedded in the manhole cover locking groove 8. The locking plate groove 10 on the side fixing ear 13 and the locking plate groove 10 in the manhole cover locking groove 8 are correspondingly set. The locking pin 4 is embedded in the locking plate groove 10 and can rotate in the locking plate groove 10. The side connecting sleeve 14 is embedded in the manhole cover connecting groove 7 through the connecting pin 3.

[0018] The above describes the main components and their positional relationships of the manhole cover body 2, as well as its connection relationship with the manhole cover mounting frame 1. (See attached diagram.) Figure 4 .

[0019] 1. Manhole cover installation frame; 2. Manhole cover body; 3. Connecting pin; 4. Locking pin; 5. Ground frame; 6. Underground frame; 7. Manhole cover connecting groove; 8. Manhole cover locking groove; 9. Pin hole; 10. Locking plate groove; 11. Bottom parallel convex sliding strip; 12. Side end fixing ear; 13. Side end connecting sleeve ear; 14. Bottom triangular mesh; 15. Mesh fixing frame; 16. Drain outlet; 17. Connecting sliding groove; 18.

[0020] In practical applications, the installation process of this manhole cover is very simple. First, align the side connecting lug 14 of one end of the manhole cover body 1 with the manhole cover connecting groove 7, and insert the connecting pin 3, allowing the manhole cover body 1 to rotate flexibly around the connecting pin. Next, embed part of the underground frame 6 into the pre-dug manhole, ensuring that the ground frame 5 is flush with the road surface. Then, insert the side fixing lug 13 of the other end of the manhole cover body 1 into the manhole cover locking groove 8, at which point the locking plate groove 10 on the side fixing lug 13 precisely corresponds to the locking plate groove in the manhole cover locking groove 10. Finally, insert the locking pin 4 into these two corresponding locking plate grooves 10. Since the locking pin 4 can rotate within the locking plate groove 10, this ensures that the manhole cover body 1 is firmly fixed on the manhole cover mounting frame 1, and also facilitates opening the manhole cover for maintenance and other work when needed.

[0021] In daily use, when rainwater or other debris needs to be drained into the sewer, the water flows in through several sets of equally spaced drain outlets 17 on the manhole cover. Floating debris, such as leaves and plastic bags, is intercepted by the triangular mesh screens 15 at the bottom of the cover. Three sets of these triangular mesh screens 15 are arranged side-by-side, with the central mesh screen 15 being deeper than the two side mesh screens. This design makes it easier for debris to be collected in the shallower mesh screens on the sides, preventing it from accumulating in one place and affecting drainage. Simultaneously, parallel convex sliding strips 12 are provided on the bottom side of the manhole cover 11, arranged parallel to each other at the spacing of the drain outlets 17. These strips cooperate with the connecting grooves on the mesh fixing frame 16, enhancing the overall structural stability of the manhole cover and facilitating the removal of the triangular mesh screens 15 from the manhole cover 11 for cleaning. This effectively reduces the problem of debris clogging the sewer and minimizes the cost and effort of retrieving debris that has accidentally fallen into the sewer.

[0022] Moreover, this tight connection structure greatly reduces the possibility of the manhole cover being stolen by cutting the connecting rod. Traditional manhole cover connections are relatively simple, making them easy for criminals to use tools to cut the connecting rod and steal the cover, posing a threat to urban safety. This manhole cover, however, uses connecting rod 3, locking pin 4, and precise fit between all parts to form a tight, integrated structure between the cover and its mounting frame, increasing the difficulty of theft and ensuring the normal operation of the urban drainage system and the safety of citizens. Therefore, it is highly suitable for widespread use in urban water conservancy projects.

[0023] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
