The diversion hole 7 is opened on the diversion turntable 6. The drive motor 8 is fixedly installed in the diversion box 1, and the output shaft of the drive motor 8 is fixedly connected to the bottom of the diversion turntable 6;

[0026] The connecting mechanism includes a sliding pipe 9, a guide pipe 10, two fixed plates 11 and two hydraulic cylinders 12. The sliding pipe 9 is slidably installed in the diversion pipe 3, the guide pipe 10 is fixedly installed on the top of the sliding pipe 9, the two fixed plates 11 are fixedly installed on the outer wall of the guide pipe 10, the two hydraulic cylinders 12 are fixedly installed on the bottom inner wall of the diversion box 1, and the output shafts of the two hydraulic cylinders 12 are fixedly connected to the two fixed plates 11 respectively.

[0027] like Figure 3 As shown, the anti-backflow mechanism includes a guide ring 13, a plurality of positioning blocks 14 and a floating ball 15. The guide ring 13 is fixedly mounted on the inner wall of the shunt pipe 3, and a plurality of positioning blocks 14 are equidistantly mounted on the inner wall of the shunt pipe 3 in an annular shape. The floating ball 15 is arranged between the guide ring 13 and the positioning blocks 14.

[0028] By providing an anti-backflow mechanism, it is possible to prevent rainwater or sewage from flowing back into the rainwater pipe 4 and the sewage pipe 5 when the amount of rainwater or sewage discharged is large.

[0029] like Figure 3 As shown, a connecting pipe 16 is fixedly installed at the bottom of the diversion turntable 6, and the bottom of the connecting pipe 16 extends into the corresponding guide pipe 10;

[0030] By providing the connecting pipe 16 , the guide pipe 10 can be sleeved on the connecting pipe 16 to prevent rainwater or sewage from splashing out.

[0031] like Figure 3 As shown, an annular groove 17 is provided at the bottom of the guide ring 13, and the annular groove 17 is adapted to the float 15;

[0032] By providing the annular groove 17 , the float 15 can be stuck in the annular groove 17 after the float 15 rises, thereby preventing rainwater or sewage from flowing back.

[0033] like Figure 3 As shown, a support base is fixedly installed at the bottom of the driving motor 8, and four support legs are fixedly installed at the bottom of the support base, and the four support legs are fixedly connected to the bottom inner wall of the shunt box 1;

[0034] By providing the support seat and the support legs, the drive motor 8 can be supported and fixed, thereby improving the stability of the drive motor 8.

[0035] like Figure 3 As shown, the outer diameter of the connecting pipe 16 is slightly smaller than the inner diameter of the top of the guide pipe 10, and the outer diameter of the sliding pipe 9 is slightly smaller than the inner diameter of the diverter pipe 3;

[0036] The above-mentioned size setting makes it easy for the flow guide pipe 10 to be sleeved on the connecting pipe 16 and for the sliding pipe 9 to slide in the flow distribution pipe 3 .

[0037] The working principle of the rainwater and sewage diversion and discharge device for sponge cities provided by the utility model is as follows:

[0038] Step 1: When it is not raining, the diversion hole 7 faces the diversion pipe 3 connected to the sewage pipe 5, so that the sewage in the water inlet pipe 2 is discharged into the sewage pipe 5 through the guide pipe 10, the slide pipe 9 and the diversion pipe 3, and is transported to the sewage treatment plant through the sewage pipe 5;

[0039] The second step: when it rains, the driving motor 8 is started, the driving motor 8 drives the diversion turntable 6 to rotate, so that the diversion hole 7 is directly opposite to the diversion pipe 3 connected to the rainwater pipe 4, the hydraulic cylinder 12 is started, the hydraulic cylinder 12 drives the fixed plate 11 to move upward, the fixed plate 11 drives the guide pipe 10 and the sliding pipe 9 to move upward, so that the guide pipe 10 is sleeved on the connecting pipe 16, and the rainwater is introduced into the rainwater pipe 4 through the guide pipe 10, the sliding pipe 9 and the diversion pipe 3 for discharge;

[0040] The third step: when the amount of rainwater or sewage discharged in the rainwater pipe 4 and the sewage pipe 5 is large, the rainwater or sewage enters the diversion pipe 3, and the rainwater or sewage will cause the float 15 to float and get stuck in the annular groove 17 on the guide ring 13, thereby blocking the guide ring 13, thereby preventing the rainwater or sewage from flowing back.

[0041] It should be noted that the equipment structure and drawings of the utility model mainly describe the principle of the utility model.
