DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Please refer to Figure 1 - Figure 2, the present utility model provides a technical solution: a centralized water supply structure, including a tank body 1;

[0018] In the middle of the inner wall at the top end of the tank body 1, a water inlet pipe 11 penetrates and communicates. On one side of the inner wall at the bottom end of the tank body 1, a drain pipe 12 penetrates and communicates. In the middle of one side of the tank body 1, a servo motor 13 is fixedly connected by bolts. The motor shaft of the servo motor 13 penetrates the outside of the tank body 1 and is fixedly connected to a first rotating rod 14. The other end of the first rotating rod 14 is fixedly connected to one side of a fixed frame 15. A filter screen 16 is detachably installed inside the fixed frame 15. A sealing ring 17 is adhered to the outside of the fixed frame 15. The sealing ring 17 fits with the inner wall of the tank body 1. On the other side of the fixed frame 15, a second rotating rod 18 is horizontally and fixedly installed. The other end of the second rotating rod 18 is rotatably connected to the inner wall of the tank body 1 through a bearing. The controller 22 controls the servo motor 13 to work. Through the first rotating rod 14, the filter screen 16 inside the fixed frame 15 can be driven to rotate 180 degrees. Further, the water discharged from the water inlet pipe 11 can backwash the impurities on the surface of the filter screen 16, which is convenient and fast.

[0019] Inside the inner wall of the drain pipe 12, a water flow sensor 2 is fixedly connected by screws. Inside the drain pipe 12, a first solenoid valve 21 is provided. The first solenoid valve 21 is placed above the water flow sensor 2. Above the other side of the tank body 1, a controller 22 is fixedly connected by screws. By providing a water flow sensor 2 inside the drain pipe 12, the drainage volume of the drain pipe 12 can be detected, and further the usage condition of the filter screen 16 inside the tank body 1 can be detected. When the drainage volume is lower than the threshold value of the water flow sensor 2, the water flow sensor 2 transmits the data to the controller 22. Further, the controller 22 can automatically control the first solenoid valve 21 to close and at the same time control the servo motor 13 to work, so as to automatically clean the filter screen 16.

[0020] On the other side of the inner wall at the bottom end of the tank body 1, a sewage discharge pipe 3 penetrates and communicates. Inside the sewage discharge pipe 3, a second solenoid valve 31 is provided. The controller 22 can automatically control the opening and closing of the second solenoid valve 31, which is convenient for discharging the sewage generated by cleaning the filter screen 16.

[0021] When a centralized water supply structure is in use, by providing a water flow sensor 2 inside the drain pipe 12, the drainage volume of the drain pipe 12 can be detected, and further the usage condition of the filter screen 16 inside the tank body 1 can be detected. When the drainage volume is lower than the threshold value of the water flow sensor 2, the water flow sensor 2 transmits the data to the controller 22. Further, the controller 22 can automatically control the first solenoid valve 21 to close and at the same time control the servo motor 13 to work. Through the first rotating rod 14, the filter screen 16 inside the fixed frame 15 can be driven to rotate 180 degrees. Thus, the water discharged from the water inlet pipe 11 can backwash the impurities on the surface of the filter screen 16. Further, the controller 22 controls the second solenoid valve 31 to open, and the sewage generated by cleaning the filter screen 16 can be conveniently discharged through the sewage discharge pipe 3.
