For example, setting up rainwater collection systems for rainwater recycling and utilization; building sewage treatment plants to treat sewage before discharge, etc. These measures help protect the environment, the efficient use of resources, and reduce negative impacts on nature.

[0003] The publication number 'CN220133068U' "An underground rainwater and sewage pipe diversion and modification structure" discloses that rainwater generated in rainy weather can be collected through a water storage tank, so that impurities can be separated from rainwater under the action of the diversion component in the water storage tank, thereby improving the practicality of the diversion component, and rainwater that has been filtered in layers under the action of the first baffle plate and the filter net can be discharged to the surface under the action of a water pump through the through hole, so that the filtered rainwater can be used for multiple purposes, so that impurities filtered in the rainwater can be discharged into the sewage pipe under the action of the connecting pipe. However, during the actual use of the above structure, the first baffle plate and the filter net may accumulate impurities and affect the filtration process, and the rainwater is directly diverted there. If the rainfall is large, water may accumulate on the road. Therefore, in order to solve the above problems, the present application provides an underground rainwater and sewage pipe diversion structure.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0005] In order to solve the problem that impurity accumulation affects the filtering effect and only setting up diversion may cause water accumulation, the present application provides an underground rainwater and sewage pipe diversion structure.

[0021] The following is combined with Figure 1-3 This application is described in further detail.

[0022] Embodiment 1

[0023] Reference Figure 1-3 A underground rainwater and sewage pipe diversion structure includes a ground body 1, a second cylindrical groove 5 and a rectangular groove 7 connected to the second cylindrical groove 5 are arranged inside the ground body 1, a perforated plate 6 and a filter screen 8 are fixedly arranged in the rectangular groove 7 from top to bottom, a rainwater pipe 9 is arranged on the side wall of the rectangular groove 7 below the filter screen 8, a vertical rod 15 is arranged in the rectangular groove 7, and a plurality of cleaning brushes 18 are fixedly connected to the side wall of the vertical rod 15, the vertical rod 15 moves downward, the rainwater pipe 9 is not connected with the rectangular groove 7, and the cleaning brushes 18 move downward to the upper surface of the perforated plate 6 and the filter screen 8 respectively.

[0024] A first cylindrical groove 4 is provided inside the ground body 1, and the first cylindrical groove 4 is connected with the rectangular groove 7 through the water groove 14, and the connecting position is located below the filter 8. When the rain is heavy, the rainwater can be directly discharged through the first cylindrical groove 4 via the rectangular groove 7. A telescopic rod 16 is fixedly connected to the lower wall of the rectangular groove 7, and the telescopic rod 16 is fixedly connected to the vertical rod 15, and the vertical rod 15 is elastically connected to the lower wall of the rectangular groove 7 through a spring 17.

[0025] A sliding groove 21 is provided on the side wall of the rectangular groove 7 located on one side of the rainwater pipe 9 , and a closing plate 20 is slidably provided in the sliding groove 21 . The closing plate 20 is fixedly connected to a connecting plate 19 , and the connecting plate 19 is rotatably connected to the vertical rod 15 .

[0026] An isolation plate 13 is fixedly arranged between one side of the filter screen 8 and the lower wall of the rectangular groove 7, and a sewage trough 11 is formed between the isolation plate 13 and the side wall of the rectangular groove 7. A sewage pipe 12 is arranged through the side wall of the sewage trough 11. Rainwater is filtered through the perforated plate 6 and the filter screen 8 due to gravity and is directly discharged through the rainwater pipe 9. Impurities on the perforated plate 6 and the filter screen 8 fall into the sewage trough 11 under the impact of the water flow, and the mixed part of the rainwater is discharged through the sewage pipe 12.

[0027] An emergency cover 3 that can be opened by rotating is arranged above the first cylindrical groove 4. The emergency cover 3 is a cover plate with a semicircular opening commonly seen on the market. It is a common existing technology. It can be connected to the outside by rotating half a circle. It will not be described here. A filter cover 2 with a through hole is arranged above the second cylindrical groove 5 to block larger garbage as a preliminary filter during rainwater treatment. The rainwater pipe 9 is fixedly connected and connected to a drainage pipe 10, which can be connected to a rainwater well in a city pipeline.

[0028] In actual use, when the structure is in normal operation, the emergency cover 3 is closed, and rainwater falls into the rectangular groove 7 through the filter cover 2 and the second cylindrical groove 5. Due to the effect of gravity, the rainwater is filtered by the perforated plate 6 and the filter screen 8 and discharged through the rainwater pipe 9. The impurities on the perforated plate 6 and the filter screen 8 are mixed with part of the rainwater and fall into the sewage tank 11 and discharged through the sewage pipe 12.

[0029] When it rains, the impurities on the perforated plate 6 and the filter screen 8 may accumulate too much and cause blockage. At this time, the rainwater is diverted slowly. Open the filter cover 2 and press down the vertical rod 15, so that the connecting plate 19 drives the closing plate 20 to move downward, separating the rectangular groove 7 and the rainwater pipe 9. At this time, the cleaning brush 18 fits the upper surface of the perforated plate 6 and the filter screen 8, and the vertical rod 15 is rotated to rotate the cleaning brush 18 to move the impurities on the perforated plate 6 and the filter screen 8. Since the rainwater pipe 9 is blocked, the water level in the rectangular groove 7 rises and can only be discharged through the sewage pipe 12, so that the rapid water flow drives the moved impurities into the sewage pipe 12 and discharges the impurities;

[0030] When the rainfall is heavy and the drainage speed of the diversion structure cannot ensure normal drainage, the emergency cover 3 is opened, and the rainwater is discharged into the rectangular groove 7 through the first cylindrical groove 4 and the water flow groove 14, and is directly discharged through the drainage pipe 10, reducing the possibility of water accumulation.
