Description

Technical Field

[0001] The utility model belongs to the technical field of road drainage, and in particular relates to a municipal road drainage structure. Background Art

[0002] Municipal road drainage refers to the rainwater drainage system on urban roads, which is used to remove rainwater accumulated on the road during rainfall to prevent water accumulation on the road and ensure traffic safety. The municipal road drainage system usually includes rainwater sewers, rainwater pipe networks, rainwater inlets, rainwater grates and other facilities. The design of the municipal road drainage system needs to consider factors such as urban planning, rainfall, road slope, and drainage pipe diameter to ensure that rainwater can be discharged quickly and effectively. The design requires flow calculation, pipe network layout, rainwater inlet setting and other work. Common calculation methods include Manning's formula, flood frequency analysis, etc.

[0003] At present, the municipal road drainage structure of the prior art has the following disadvantages during use:

[0004] On the one hand, a filter structure is set inside the drainage pipe, but the impurities or dirt intercepted by the filter structure are not easy to clean, which makes cleaning more troublesome;

[0005] Secondly, the sewer pipes are connected to the outside. In the summer, when the rain is not in season, there is a lack of structures that can reduce the odor. For this reason, we proposed a municipal road drainage structure. Utility Model Content

On the other hand, it can scrape out the impurities intercepted on the curved surface of the top of the curved filter, making it more convenient to manually open the manhole cover to clean out the impurities in the subsequent cleaning.

[0010] As a preferred implementation, the length of the water guide plate is equal to the length of the middle bridge plate.

[0011] As a preferred embodiment, the disassembly and assembly structure includes a strap a fixed to the bottom end of the arc filter, which is movably overlapped with a strap b fixed to the bottom outer wall of the water guide plate, and a strap c is fixed to the outer periphery of the top end of the arc filter.

[0012] As a preferred implementation, the strap c is fixed in a strap groove provided at the top end of the middle strap plate by two screws.

[0013] As a preferred embodiment, the deodorizing scraping structure includes a bevel gear a rotatably connected by a rotating shaft at the center of the bottom end of the middle sealing plate, the top of the rotating shaft extends to the groove provided at the top of the middle sealing plate, and is fixed to the rotating block, the top of the rotating block is fixed with an n-shaped handle, the bottom of the bevel gear a is meshingly connected with a bevel gear b, the bevel gear b is fixed to the outside of the bidirectional screw, both ends of the bidirectional screw are rotatably connected to the drainage pipe, the outer side of the bidirectional screw is threadedly connected to two symmetrically arranged movable blocks, the bottom ends of the movable blocks are hinged with push-pull rods, the bottom ends of the push-pull rods are hinged with closed scrapers, the opposite ends of the two closed scrapers are rotatably connected to the drainage pipe through a connecting shaft, and the scraping surfaces of the opposite ends of the two closed scrapers are movably fitted to the surface of the arc filter.

[0014] As a preferred embodiment, blocking blocks are movably fitted on the tops of the ends of the two closed scrapers that are away from each other, and the blocking blocks are fixed to the inner wall of the drainage pipe.

[0015] Compared with the prior art, the municipal road drainage structure provided by the utility model has at least the following beneficial effects:

[0016] (1) Through the effect of the anti-odor scraping structure, when the top of the two closed scrapers shown in the attached figure is flush with the top of the middle slat, the odor reflected from the underground pipeline can be reduced, especially in the summer rainy off-season, which has a good effect of reducing the odor. Secondly, it is easy to scrape out the impurities and dirt intercepted on the surface of the four arc-shaped filter screens, so as to facilitate manual cleaning and improve cleaning efficiency;

[0017] (2) By means of the disassembly and assembly structure, when the arc filter needs to be disassembled and replaced, the bottom strip a of the arc filter can be removed from the strip b by loosening the two screws.

[0030] The disassembly and assembly structure can facilitate the disassembly and assembly of the arc filter 7;

[0031] On the one hand, the anti-odor scraping structure 6 can seal the drainage pipe 1 and reduce the odor reflected from the underground pipe 4. On the other hand, it can scrape out the impurities intercepted on the top curved surface of the curved filter 7, making it more convenient to manually open the manhole cover 3 to clean the impurities.

[0032] Further as Figure 1-4 As shown, it is worth to explain in detail that the length of the water guide plate 8 is equal to the length of the middle strap 5.

[0033] The water guide plate 8 enables the incoming sewage to be filtered through the surface of the arc-shaped filter screen 7 to intercept dirt and impurities.

[0034] Further as Figure 1-4 As shown, it is worth explaining in detail that in order to facilitate the disassembly and assembly of the arc filter 7, a disassembly and assembly structure is provided, including a strap a72 fixed to the bottom end of the arc filter 7, and the strap a72 is movably overlapped on the strap b fixed to the outer wall of the bottom of the water guide plate 8, and a strap c73 is fixed to the outer periphery of the top end of the arc filter 7, and the strap c73 is fixed to the strap groove provided at the top end of the middle strap 5 by two screws 71.

[0035] Among them, a screw hole matching with the screw 71 is provided on the inner bottom wall of the mounting groove, and a through hole matching with the screw 71 is opened on the mounting strip c73.

[0036] Further as Figure 1-4 As shown, it is worth explaining in detail that, in order to synchronously scrape out the dirt intercepted on the surfaces of the four arc-shaped filter screens 7 on the one hand, and to reduce the anti-odor effect on the other hand, an anti-odor scraping structure 6 is provided, which includes a bevel gear a64 rotatably connected to the center of the bottom end of the middle sealing plate 2 through a rotating shaft 61, the top end of the rotating shaft 61 extends to the groove provided at the top of the middle sealing plate 2, and is fixedly connected to a rotating block 62, the top end of the rotating block 62 is fixedly connected to an n-shaped handle 63, and a bevel gear b65 is meshedly connected to the bottom of the bevel gear a64, and the bevel gear b65 is fixedly connected to the outer side of a bidirectional screw 66, and the bidirectional screw Both ends of 66 are rotatably connected in the drainage pipe 1, and the outer side of the bidirectional screw 66 is threadedly connected to two symmetrically arranged movable blocks 67, the bottom ends of the movable blocks 67 are hinged with push-pull rods 68, and the bottom ends of the push-pull rods 68 are hinged with closed scrapers 69, and the opposite ends of the two closed scrapers 69 are rotatably connected in the drainage pipe 1 through the connecting shaft 610, and the scraping surfaces of the opposite ends of the two closed scrapers 69 are movably fitted on the surface of the arc filter 7, and the tops of the opposite ends of the two closed scrapers 69 are movably fitted with blocking blocks 611, and the blocking blocks 611 are fixed to the inner wall of the drainage pipe 1.
