[0021] The present utility model will be clearly and completely described below in conjunction with the drawings and embodiments:
[0022] As Figures 1 to 4As shown in the figure, a rainwater runoff diversion device for water supply and drainage according to the present utility model includes a cylinder body 1. The interior of the cylinder body 1 is divided into an upper filtering chamber 3 and a lower sewage discharge chamber 4 by a partition plate 2. An inlet 5 and an outlet 6 are provided on the cylinder body 1 corresponding to the filtering chamber 3, and a sewage discharge port 7 is provided on the cylinder body 1 corresponding to the filtering chamber 3. Among them, a filter screen 8 is provided at one end of the filtering chamber 3 close to the outlet 6 to further filter the discharged rainwater. A runoff diversion port 9 is penetrated through the partition plate 2, and the sewage discharge chamber 4 and the filtering chamber 3 are communicated through the runoff diversion port 9. Floating bodies 10 are provided in both the sewage discharge chamber 4 and the filtering chamber 3 through connecting shafts 14. The connecting shafts 14 are movably arranged on supporting rods 11 in the cylinder body 1. A mesh cover 13 is provided on the partition plate 2 outside the runoff diversion port. The mesh cover 13 is coaxially arranged with the connecting shaft 14, and a through hole for the connecting shaft 14 to movably penetrate is provided at the top of the mesh cover 13. Among them, the floating body 10 located in the filtering chamber 3 is located above the mesh cover 13 to ensure that the floating body 10 can move upward without being affected when the water flow is large, and to ensure that the runoff diversion port 9 can be normally closed. In the present utility model, through the setting of the mesh cover 13, while ensuring that rainwater passes through the runoff diversion port 9, the dirt carried in the rainwater can be intercepted and filtered, avoiding the blockage of the runoff diversion port 9 and the accumulation of dirt inside the sewage discharge chamber 4, ensuring the normal operation of the device and reducing the difficulty of cleaning the dirt.
[0023] Further, the mesh cover 13 is a net-like structure with a hollow interior and an open bottom end, ensuring the smooth passage of rainwater and intercepting dirt in the filtering chamber 3. Only the filtering chamber 3 needs to be cleaned regularly. Among them, the mesh cover 13 is preferably set as a cylindrical structure to ensure the filtering area. In addition, a diversion platform 15 is further provided at the top of the mesh cover 13, and the diversion platform 15 is a conical structure. The bottom end of the diversion platform 15 preferably has the same size as the top end of the mesh cover 13. The setting of the conical diversion platform 15 can avoid the accumulation of dirt at the bottom of the mesh cover 13. The surface of the diversion platform 15 is preferably smooth so that the dirt can slide down smoothly along the smooth slope of the diversion platform 15.
[0024] Further, a cleaning ring 16 is coaxially arranged outside the mesh cover 13, and bristles in contact with the mesh cover 13 are provided on the inner side of the cleaning ring 16. A connecting rod 12 is provided on the cleaning ring 16, and the connecting rod 12 is connected to the floating body 10 located in the filtering chamber 3. As the water flow increases, the floating body 10 will rise and synchronously drive the cleaning ring 16 to rise, thereby achieving the purpose of cleaning the outside of the mesh cover 13, timely cleaning the dirt adhered to the outside of the mesh cover 13, and avoiding blocking the mesh holes and affecting the filtering efficiency. At the same time, for dirt that is difficult to remove, during regular manual cleaning, the floating body 10 can be pulled up and down to drive the cleaning ring 16 to move up and down to clean the mesh cover 13, improving the convenience of cleaning the mesh cover 13. The height of the mesh cover 13 is not greater than the distance from the floating body 10 in the sewage discharge chamber 4 to the runoff diversion port 9 to ensure that when the floating body 10 moves upward to block the runoff diversion port 9, the cleaning ring 16 can complete the cleaning of the mesh cover 13.
[0025] Furthermore, the filter screen 8 in this embodiment is arranged in a radially bent and circular manner along the cylinder body 1, which can increase the filtering area of the filter screen 8 and ensure the filtering efficiency. In addition, the floating body 10 in this embodiment is a floating ball with a smooth surface; the diameter of the floating body 10 located in the filtering chamber 3 is larger than the diameter of the flow diversion port, so as to ensure that when the water flow rate is large, the floating ball moves upward to block the flow diversion port 9. At this time, the water flows through the filter screen 8 for filtration and is discharged from the water outlet 6.
[0026] When the utility model is working, water flows into the cylinder body 1 through the water inlet 5. Since the diameters of the water inlet 5 and the water outlet 6 are usually three to four times that of the sewage outlet 7, when the water inflow rate of the water inlet 5 is less than the flow rate of the sewage outlet 7, rainwater enters the sewage chamber 4 through the flow diversion port 9 for normal flow diversion; when the water inflow rate of the water inlet 5 is greater than the flow rate of the sewage outlet 7, the excess water flow will lift the floating ball. At this time, the flow diversion port 9 is closed, and rainwater passes through the filter screen 8 and enters the reservoir to filter out clean rainwater, completing the flow diversion process; during this process, through the setting of the mesh cover 13, the interception and filtration of dirt are effectively realized, avoiding the blockage of the flow diversion port 9 and the sewage chamber 4. At the same time, the dirt is intercepted in the filtering chamber 3, which is convenient for subsequent regular cleaning. The structure is simple, the operation is convenient, and the practicability is strong.
