Detailed implementation mode

[0021] The present utility model will be further described below in conjunction with the accompanying drawings and implementation modes.

[0022] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , wherein, Figure 1 is a schematic structural diagram of a preferred embodiment of a municipal rainwater drainage structure for preventing blockage and odor overflow provided by the present utility model; Figure 2 is Figure 1 the sectional structural diagram shown; Figure 3 is Figure 2 the enlarged schematic diagram of a part of the structure shown; Figure 4 is Figure 2 the enlarged schematic diagram of a part of the structure shown. A municipal rainwater drainage structure for preventing blockage and odor overflow includes a drain pipe 1. At the bottom between the inner walls of the drain pipe 1, a conical cylinder 9 is fixedly connected. On the inner wall of the conical cylinder 9, evenly distributed guide rods 11 are fixedly connected. At the top of each guide rod 11, a limiting ring 12 is fixedly connected. The outer parts of the guide rods 11 all penetrate and are slidably connected with collars 15. Between the collars 15, an airbag 13 is fixedly connected. At the bottom of the airbag 13, two connecting rods 17 are fixedly connected. At the bottom of each connecting rod 17, a sealing plate 14 is fixedly connected. In the middle at the bottom of the conical cylinder 9, a through hole 16 is opened, and the through hole 16 penetrates and is slidably connected with the sealing plate 14. Due to the entry of rainwater, the airbag 13 is driven to float upward. At the same time, due to the arranged guide rods 11 and collars 15, the airbag 13 can float vertically. Through the floating of the airbag 13, the sealing plate 14 connected thereto is driven to rise, so as to open the through hole 16, enabling rainwater to drain through this place. After the drainage is completed, due to the lack of buoyancy of water, the sealing plate 14 drives the airbag 13 to fall downward until the sealing plate 14 seals the through hole 16 again, thereby preventing odor from emitting therefrom.

[0023] In the middle between the inner walls of the drain pipe 1, four fixing rods 7 are fixedly connected. Between the fixing rods 7, a conical guide plate 8 is fixedly connected. The filtered rainwater flows from the outer side of the inner wall of the conical cylinder 9 to the middle of the inner side under the guidance of the conical guide plate 8.

[0024] A fixing ring 5 is fixedly connected to the top between the inner walls of the drain pipe 1, enabling the filter screen 4 to be installed in the drain pipe 1. The top of the fixing ring 5 is fixedly connected with evenly distributed insertion blocks 10, which can be better installed with the fixing ring 5.

[0025] The filter screen 4 passes through and is slidably connected to the middle of the top of the fixing ring 5, and the filter screen 4 is also passed through and slidably connected with the insertion blocks 10, which can filter impurities in the rainwater and prevent the drain pipe 1 from being blocked.

[0026] A collection bucket 6 is fixedly connected to the bottom of the filter screen 4, which can collect the filtered impurities for convenient subsequent cleaning.

[0027] A cover body 2 passes through and is arranged at the top of the drain pipe 1 to prevent objects from falling into the drain pipe 1. The top of the cover body 2 is provided with evenly distributed drain ports 3, enabling rainwater to enter the interior of the drain pipe 1 through the drain ports 3.

[0028] The working principle of a municipal rainwater drainage structure for preventing blockage and odor overflow provided by the present utility model is as follows:

[0029] First, during use, the filter screen 4 is aligned with the insertion blocks 10 on the fixing ring 5 and thus installed inside the drain pipe 1, and then the cover body 2 is covered on the top end of the drain pipe 1. When draining water, rainwater enters the interior of the drain pipe 1 through the drain ports 3 and first passes through the filter screen 4 to filter the debris in the rainwater, and the filtered impurities fall into the collection bucket 6 for collection. The filtered rainwater passes through the conical guide plate 8 and flows from the outer side to the middle inside of the inner wall of the conical cylinder 9 under the guidance of the conical guide plate 8. Due to the entry of rainwater, the airbag 13 floats upward, and at the same time, due to the arranged guide rods 11 and sleeves 15, the airbag 13 can float vertically. Through the floating of the airbag 13, the sealing plate 14 connected thereto is driven to rise, thus opening the through hole 16, enabling rainwater to drain through this place. After the drainage is completed, due to the lack of buoyancy of water, the sealing plate 14 drives the airbag 13 to fall downward until the sealing plate 14 seals the through hole 16 again, thereby preventing odors from emitting therefrom.

[0030] Compared with the related technology, a municipal rainwater drainage structure for preventing blockage and odor overflow provided by the present utility model has the following beneficial effects:

[0031] The utility model provides a municipal rainwater drainage structure for preventing blockage and odor overflow. Firstly, through the mutual cooperation of the conical cylinder 9, guide rod 11, limit ring 12, airbag 13, sealing plate 14, collar 15 and through hole 16, when rainwater is drained, the rainwater enters the inner wall of the conical cylinder 9, thereby driving the airbag 13 to float upward. At the same time, due to the arranged guide rod 11 and collar 15, the airbag 13 can float vertically. Through the floating of the airbag 13, the sealing plate 14 connected thereto is driven to rise, thereby opening the through hole 16, enabling the rainwater to drain through this place. After the drainage is completed, due to the lack of buoyancy of water, the sealing plate 14 drives the airbag 13 to fall downward until the sealing plate 14 reseals the through hole 16, thereby preventing the odor from emitting therefrom and not affecting the service life due to long-term contact with water.

[0032] The utility model provides a municipal rainwater drainage structure for preventing blockage and odor overflow. Through the mutual cooperation of the fixed ring 5, filter screen 4 and collection bucket 6, when the sundries in the collection bucket 6 need to be cleaned, only the filter screen 4 needs to be lifted out of the drain pipe 1 for treatment. And through the arranged filter screen 4, the sundries in the water can be effectively filtered, preventing the inner wall of the drain pipe 1 from being blocked and affecting the drainage effect.

[0033] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present utility model.
