[0063] At the same time, through the linkage setting of the third transmission belt 33, when the first rotating rod 21 rotates, the second connecting rod 32 can be driven to rotate synchronously, thereby driving the second bidirectional screw 26 fixedly connected to the second connecting rod 32 to rotate synchronously inside the second groove plate 24, and then driving the two movable horizontal plates 28 threadedly connected to the second bidirectional screw 26 to move synchronously and in opposite directions;

[0064] The thread of the second bidirectional screw 26 is arranged opposite to the thread of the first bidirectional thread 12. When the first bidirectional thread 12 drives the two first blocking plates 14 to move away from each other, the second bidirectional screw 26 can drive the two movable horizontal plates 28 to move closer to each other. The second fixing rod 27 can support and connect the movable horizontal plate 28, and can also improve the stability of the movement of the movable horizontal plate 28.

[0065] At this time, the two movable horizontal plates 28 will drive the third blocking plate 30 to move toward one end close to each other through the telescopic rod 29 at the bottom, and move to the top of the guide groove in the shape of an inverted trapezoidal cylinder, and play a blocking effect on the top of the guide groove;

[0066] The second limiting plate 31 can limit the movement of the third blocking plate 30 on the inclined surface at the top of the V-shaped guide plate 10.

[0067] Through the telescopic setting of the telescopic rod 29, when the movable horizontal plate 28 drives the third blocking plate 30 to move, the distance between the third blocking plate 30 and the movable horizontal plate 28 can be adaptively adjusted, thereby avoiding the fixed length of the telescopic rod 29 affecting the movement of the third blocking plate 30 driven by the movable horizontal plate 28;

[0068] After the third blocking plate 30 blocks the guide groove of the V-shaped guide plate 10, the height of the rainwater-sewage mixed water accumulated on the top of the V-shaped guide plate 10 will gradually increase. When the height of the rainwater-sewage mixed water reaches the second pipe 3, it can be directly discharged from the inside of the box body 1 through the second pipe 3.

[0069] When the rainfall sensor 7 detects that the rainfall is gradually decreasing, the active motor 16 can be driven to rotate in the reverse direction;

[0070] At this time, the linkage setting of the first transmission belt 17 can drive the first bidirectional thread 12 to rotate in the opposite direction, and make the two first blocking plates 14 approach each other to block the second pipe 3;

[0071] At the same time, the linkage setting of the second transmission belt 23 can drive the first rotating rod 21 to rotate in the opposite direction, thereby driving the second blocking plate 19 to move upward, and making the second blocking plate 19 cancel the blocking effect of the flow opening opened by the fixed partition plate 8;

[0072] At the same time, through the linkage setting of the third transmission belt 33, the second bidirectional screw 26 can be driven to rotate in the opposite direction, and the two movable transverse plates 28 can be driven to move away from each other. At this time, the movable transverse plate 28 can drive the third blocking plate 30 to cancel the blocking effect on the guide groove;

[0073] At this time, the liquid whose top of the first inclined guide plate 9 is lower than the second pipe 3 will flow to the end close to the V-shaped guide plate 10 through the inclined setting of the first inclined guide plate 9, and enter the top of the V-shaped guide plate 10 through the flow opening opened in the fixed partition plate 8, and then enter the inner side of the third pipe 4 through the reserved groove opened in the V-shaped guide plate 10;

[0074] Thereby, the phenomenon of sewage accumulation inside the box body 1 can be reduced, thereby improving the internal environment of the box body 1.

[0075] The motors mentioned above are all motors with power-off self-locking capabilities, such as servo motors.

[0076] Embodiment 3:

[0078] The municipal public engineering rainwater and sewage diversion device provided in Example 1 and Example 2 is further optimized. Specifically, Figure 11-13 As shown, the filter assembly 6 includes a hollow plate 34 and a fourth sealing plate 35. A second movable groove is opened at one end of the top of the box body 1 close to the first pipe 2. The top of the box body 1 is fixedly connected to the hollow plate 34. The position and size of the hollow plate 34 correspond to the second movable groove. The top of the hollow plate 34 is rotatably connected to the fourth sealing plate 35 through a hinge. The fourth sealing plate 35 has a sealing effect on the hollow plate 34.

[0079] The filter assembly 6 also includes a movable vertical plate 36, a filter box 37, a connecting strip 38, a handle 39, a first supporting plate 40 and a second supporting plate 41. The movable vertical plates 36 are gap-fitted on both sides of the inner side of the box body 1 near one end of the first pipe 2, and a filter box 37 is arranged between the two movable vertical plates 36. The filter box 37 is far away from the end of the first pipe 2 and the bottom of the filter box 37 are provided with a plurality of filter holes, and the outer sides of both sides of the filter box 37 are fixedly connected with a plurality of connecting strips 38, and the filter box 37 is slidably connected to the movable vertical plate 36 through the connecting strips 38. The handles 39 are fixedly connected on both sides of the top of the filter box 37, and the first supporting plate 40 is fixedly connected to the bottom of the movable vertical plate 36. The first supporting plate 40 is extended to the bottom of the filter box 37 near one side of the filter box 37, and the second supporting plate 41 is fixedly connected to both sides of the box body 1 near one end of the first pipe 2, and the second supporting plate 41 is arranged below the first supporting plate 40.

[0080] The filter assembly 6 also includes a double-headed motor 42, a fixed seat 43, a second rotating rod 44, a connecting belt 45, a first roller 46 and a second rotating roller 47. The double-headed motor 42 is fixedly connected to the center position of the top of the box body 1, and the two sides of the top of the box body 1 are fixedly connected to the fixed seat 43. The position of the fixed seat 43 corresponds to the double-headed motor 42. The output ends on both sides of the double-headed motor 42 are fixedly connected to the second rotating rod 44, and the side of the second rotating rod 44 away from the double-headed motor 42 is rotatably connected to the fixed seat 43. The outer side of the second rotating rod 44 is fixedly connected to the connecting belt 45, and the second rotating The rod 44 plays a role in winding and reeling the connecting belt 45. A third movable groove is provided on both sides of the hollow plate 34 near one end of the double-headed motor 42. The top of the inner side of the third movable groove is rotatably connected to the first roller 46. The middle part of the two sides of the inner side of the hollow plate 34 is rotatably connected to the second roller 47. The end of the connecting belt 45 away from the second rotating rod 44 passes through the inner side of the third movable groove and bypasses the top of the second roller 47 to extend to the inner side of the box body 1. The end of the connecting belt 45 away from the second rotating rod 44 is fixedly connected to the top of the movable vertical plate 36, and the first roller 46 plays a tensioning role on the connecting belt 45.

[0081] Specifically: by setting the filter holes provided in the filter box 37, the sewage discharged from the first pipe 2 into the inner side of the box body 1 can be filtered, and larger impurities such as branches, stones, garbage, etc. that may be contained in the sewage can be intercepted, thereby preventing the impurities from entering the inner side of the second pipe 3 or the third pipe 4 and causing blockage;

[0082] After the accumulation inside the filter box 37 reaches a certain level, the double-headed motor 42 is turned on to drive the second rotating rod 44 to rotate, and the connecting belt 45 is reeled up. At this time, the length of the connecting belt 45 is shortened, thereby driving the movable vertical plate 36 to move upward. The first supporting plate 40 fixedly connected to the bottom of the movable vertical plate 36 can support the filter box 37, thereby driving the filter box 37 to move upward synchronously. The second roller 47 and the first roller 46 can be used to improve the stability of the lifting of the movable vertical plate 36 by the connecting belt 45.

[0083] At the same time, the fourth blocking plate 35 is turned over to cancel the blocking effect on the top of the hollow plate 34. When the movable vertical plate 36 drives the movable vertical plate 36 to move to the inside of the hollow plate 34, the handle 39 can be pulled to drive the connecting strip 38 to be pulled out of the inside of the movable vertical plate 36, so that the filter box 37 can be separated from between the two movable vertical plates 36, so that the impurities inside the filter box 37 can be cleaned.

[0084] Subsequently, the filter box 37 can be reinserted between the two movable vertical plates 36 and connected to the movable vertical plates 36 via the connecting strips 38. Subsequently, by loosening the length of the connecting belt 45, the movable vertical plates 36 are lowered inside the box body 1. By setting the second supporting plate 41, the first supporting plate 40 can be supported, thereby limiting the position of the filter box 37 inside the box body 1, thereby facilitating the filter box 37 to filter the sewage discharged from the first pipe 2.

[0085] The motors mentioned above are all motors with power-off self-locking capabilities, such as servo motors.
