A diversion pipe 221 is connected and arranged at the end of the inclined pipe of the inclined tee 220. The end of the diversion pipe 221 is connected and arranged with a confluence pipe 230. The confluence pipe 230 serves as the total diversion pipe to introduce the sewage overflowing from the main drainage pipe 210 into the overflow riser 410;

[0033] Please continue to refer to Figure 3 , the sewage protection component 300 is connected and arranged with the main drainage component 200 to assist in preventing overflow of the toilet sewage. The sewage protection component 300 includes a sewage pipe 310 connected and arranged with the confluence pipe 230.

[0039] Working principle: When the utility model is in use, when the main drain pipe 210 has a backflow situation, the sewage is transported through the diversion pipe 221 into the confluence pipeline 230, and then introduced into the overflow riser 410. The overflow riser 410 is used as the drainage channel after overflow, enabling the backflow sewage to be discharged in time. Moreover, during backflow, the sewage is collected in the overflow riser 410 until it reaches the position of the liquid level sensor 420. The liquid level sensor 420 detects the overflow information, uploads the backflow information to the remote terminal, and controls the solenoid valve 421 to open, realizing synchronous drainage alarm, and striving for valuable time for emergency treatment and rescue, so as to reduce the risk of people's property losses caused by indoor backflow sewage in low-rise buildings of high-rise buildings;

[0040] Moreover, when the confluence pipeline 230 is blocked, the upward flowing water flows through the half tee 320 and the through pipe 321 into the anti-backflow pipe 330, and then is led out through the docking of the anti-backflow pipe 330 and the overflow riser 410, preventing the confluence pipeline 230 from being blocked and not being processed in time, resulting in backflow into the toilet and then into the bathroom.

[0041] Although the present utility model has been described above with reference to the embodiments, however, without departing from the scope of the present utility model, various improvements can be made to it and components therein can be replaced with equivalents.
