Example Embodiment
[0046] Example one
[0047] Such as Figure 1-4 As shown, a diversion system for controlling sewage and initial rainwater pollution includes a rainwater pipe 1, a sewage pipe 2 and a diversion control unit 3. The rainwater pipe 1 is parallel to the sewage pipe 2, and the rainwater pipe 1 is provided with several diversions. Control unit 3, the diversion control unit 3 is connected to the sewage pipe 2 through the diversion pipe;
[0048] The diversion control unit 3 includes a diversion well 4, one side of the diversion well 4 is provided with a first inlet 5, the first inlet 5 corresponds to the other side of the diversion well 4 is provided with a first outlet 6, the first inlet 5 and the first outlet 6 Connect the rainwater pipe 1 on both sides of the shunt well 4 respectively;
[0049] The diversion well 4 is provided with a second outlet 7 on the side close to the sewage pipe 2, and the second outlet 7 is connected to the inlet end of the diversion pipe, and the outlet end of t...

[0058] Example two
[0059] Such as Figure 5 As shown, as a specific implementation, the passage control unit 8 includes a dynamic power transmission mechanism 81, a lifting mechanism 82, an opening and closing mechanism 83, and a resetting mechanism 84. The dynamic power transmission mechanism 81 is connected to the opening and closing mechanism through the lifting mechanism 82. 83. The opening and closing mechanism 83 is arranged on the second outlet 7 to control the opening of the second outlet 7; the reset mechanism 84 is connected to the lifting mechanism 82 to drive the opening and closing mechanism 83 to reset;
[0060] The dynamic power transmission mechanism 81 includes an impeller 811, an input shaft 812, a reversing transmission mechanism 813 and an output shaft 814;
[0061] The lifting mechanism 82 includes a gear 821 and a rack 822;
[0062] The opening and closing mechanism 83 includes a valve plate 831 and a sliding seat 832;
[0063] The reset mechanism 84 includes a ...
Example Embodiment
[0071] Example three
[0072] Such as Figure 6-7 As shown, and further, as an optimization of the second embodiment, the output shaft 814 is connected to a limit mechanism. The limit mechanism includes a ratchet wheel 851, a pawl 852, a spring 853, a slider 854, a sliding rail 855, a connecting rod 856 and a float 857, the ratchet wheel 851 is fixed on the output shaft 814, the ratchet wheel 851 is matched with the pawl 852, the pawl 852 is connected to the slider 854 through a pin, and a spring 853 is arranged between the bottom of the pawl 852 and the slider 854, the slider 854 is slidably connected to the sliding rail 855 in the diversion well 4, the bottom of the sliding block 854 is fixedly connected to the upper end of the connecting rod 856, and the lower end of the connecting rod 856 is fixedly connected to the floating ball 857.
[0073] The floating ball 857 is affected by the liquid level in the diversion well 4. When there is no liquid level or the liquid level is low...
