Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 and 2, the novel overflow drainage system for the water reservoir comprises an overflow pipe, a sewage discharge pipe 1, a drainage ditch 2 and a water collection pit, wherein the upper end of the overflow pipe is a water inlet and is arranged in the water reservoir and the height of the overflow pipe is flush with the overflow water level of the water reservoir; the lower end of the overflow pipe is a water outlet and is arranged right above the drainage ditch; in the embodiment, the overflow pipe comprises an upper-section pipe body 3, a middle-section pipe body 4 and a lower-section pipe body 5 which are connected with each other, the upper-section pipe body, the middle-section pipe body and the lower-section pipe body are straight pipes, the upper-section pipe body is arranged in the reservoir, the upper end of the upper-section pipe body is flush with the overflow water level, and the upper-section pipe body is fixedly arranged on the side wall of the reservoir through a pipe hoop; the middle section pipe body is communicated with the lower end of the upper section pipe body and the upper end of the lower section pipe body, and the middle section pipe body penetrates through the wall of the reservoir; the lower section pipe body is arranged outside the water storage tank, and the lower end of the lower section pipe body is arranged above the drainage ditch.
