The side of described well body 1 is provided with described collecting fitting 8, and side relative with described collecting fitting 8 on described well body 1 is provided with described overflow pipe 10, and the height of described overflow pipe 10 is lower than described collecting fitting 8. On described well body 1 between described collecting fitting 8 and overflow pipe 10 and near shown overflow pipe 10 positional symmetry be provided with described intercepting sewer 9. The height of described intercepting sewer 9 is near the bottom of shown well body 1, and lower than described overflow pipe 10.
Between described collecting fitting 8 and overflow pipe 10, location roughly halfway up is provided with described downflow weir 11. The inner chamber of described well body 1 is divided into two cavitys in left and right, the intake antrum 4 being respectively connected and the second chamber 101 with described collecting fitting 8 by described downflow weir 11. Described division board 7 it is provided with between described downflow weir 11 and the lower end of overflow pipe 10, the setting substantially vertical with described downflow weir 11 of described division board 7, described division board 7 will be kept apart between described overflow pipe 10 and intercepting sewer 9, described second chamber 101 is divided into upper and lower two chambeies by described division board 7, the overflow cavity 6 being respectively connected with described overflow pipe 10 and the drain chamber 5 being connected with described intercepting sewer 9.With the downside of described division board 7 junction on described downflow weir 11, the position of lower end is provided with described louvered valve 14, downflow weir 11 between described louvered valve 14 and described downflow weir 11 and described division board 7 junction is provided with spilled water hole 12, preferably, described spilled water hole 12 can arrange one or more. It is connected with spilled water hole 12 by described louvered valve 14 between described intake antrum 4 and drain chamber 5.
As in figure 2 it is shown, the upper end of described downflow weir 11 is lower than the upper end of described collecting fitting 8, higher than the upper end of described overflow pipe 10. Preferably, the shaped form that the upper end of described downflow weir 11 is low in centre, two ends are high, the least significant end of this curve is lower than the upper end of described collecting fitting 8, higher than the upper end of described overflow pipe 10; Described division board 7 is curved slab, relatively low in the middle of it, and both sides tilt, and its one end is connected on described downflow weir 11, is positioned at the top of described spilled water hole 12, and other end is connected on the well body 1 being positioned at described overflow pipe 10 lower end.

As shown in Figure 1 and Figure 2, being provided with described float 13 in the both sides of described downflow weir 11, described float 13 vertically can move up and down on described downflow weir 11. As shown in Figure 6, described louvered valve 14 includes flexible strand 141, baffle plate 142 and rotates axle 143, and described baffle plate 142 has multiple, laterally uniform on described downflow weir 11. The two ends of described baffle plate 142 are provided with described rotation axle 143, and one end that described rotation axle 143 is not connected with described baffle plate 142 is arranged on described downflow weir 11, and described rotation axle 143 is free to rotate relative to described downflow weir 11. Described flexible strand 141 is wrapped on described rotation axle 143, thus being together in series by all rotation axles 143, the upper end of described flexible strand 141 is connected with described float 13. When described float 13 rises, driving described rotation axle 143 along rotating clockwise shown in Fig. 6, described baffle plate 142 also rotates clockwise, thus reducing the aperture of described louvered valve 14. When described float 13 declines, it is arranged in baffle plate 142 described in the water jet propulsion of intake antrum 4 along rotating counterclockwise shown in Fig. 6, thus increasing the aperture of described louvered valve 14.
The work process of confluence of rainwater and sewage cut-off equipment of the present invention is:
As shown in Figure 3, Figure 4, when dry season sewage or early-stage rainwater discharge less time, sewage and early-stage rainwater enter described intake antrum 4 by described collecting fitting 8, owing to water level is relatively low, described float 13 is positioned at relatively low position, described louvered valve 14 is in the state that aperture is bigger, so sewage and rainwater enter described drain chamber 5 by described louvered valve 14, flows into sewage treatment plant again through described intercepting sewer 9.
As shown in Figure 5, along with the continuous of amount of rainfall increases after entering rainy season, water level in described intake antrum 4 can increase, described float 13 rises with water level simultaneously, described louvered valve 14 is made to be in the state that aperture is less, reduce the rainwater flow flowed in described drain chamber 5, it is to avoid excessive rainfall enters sewage treatment plant by described drain chamber 5 and intercepting sewer 9; When water level in described intake antrum 4 rises to the upper end of described downflow weir 11, rainwater in described intake antrum 4 can overflow across described downflow weir 11, flow in described overflow cavity 6, at this moment owing to the aperture of described louvered valve 14 is only small, so overwhelming majority rainwater can overflow across described downflow weir 11 and flow in described overflow cavity 6, and entered in water body by described overflow pipe 10.After rainfall terminates, described intake antrum 4 middle water level begins to decline, described float 13 is also with water level decreasing, time below the upper end of water level decreasing to described downflow weir 11, rainwater can not overflow across described downflow weir 11, now owing to described float 13 is still in higher position, described louvered valve 14 is still in the less state of aperture, so the rainwater in described intake antrum 4 flows in described drain chamber 5 mainly through described spilled water hole 12, make described intake antrum 4 middle water level can continue to decline, so that described float 13 declines, increase the aperture of described louvered valve 14, so that the rainwater in described intake antrum 4 can enter in described drain chamber 5 by described louvered valve 14, sewage treatment plant is flowed into finally by described intercepting sewer 9.
Owing to being provided with described downflow weir 11, when extraneous water body water level rises, water in extraneous water body pours in down a chimney in described overflow cavity 6 by described overflow pipe 10, described downflow weir 11 can prevent the water in extraneous water body from pouring in down a chimney into described intake antrum 4 and drain chamber 5, thus avoiding the water in extraneous water body to enter sewage treatment plant in a large number.
