[0030] [First embodiment]

[0031] like Figure 1-5The figure shows a micro-rain self-driven intelligent rainwater and sewage diversion device provided by the first embodiment of the utility model, comprising a box body 1, on which a mixing port 11, a sewage port 12 and a rainwater port 13 are respectively opened; rainwater and sewage flow into the box body 1 through the mixing port 11, the mixing port 11 is arranged on one side of the box body 1, and the mixing port 11 is externally connected to a mixing pipe. On sunny days, sewage flows into the mixing port 11, and on rainy days, rainwater flows into the mixing port 11.

[0032] The sewage outlet 12 is connected to the sewage pipe network externally, and is arranged at the bottom of the box body 1 and close to the mixed flow outlet 11, so that when sewage enters the mixed flow outlet 11, it can be discharged from this outlet; the rainwater outlet 13 is connected to the rainwater pipe network externally, and is arranged at the bottom of the box body 1 and far away from the mixed flow outlet 11. When rainwater enters the mixed flow outlet 11, it is discharged from this outlet.

[0033] like Figure 1 As shown, a distinguishing opening 14 is provided on the top of the box body 1. Figure 1 As shown, the discrimination port 14 is arranged on the other side of the box body 1, and the discrimination port 14 is located at the top of the mixing port 11, and is an external rain receiving device or rainwater outlet. When it is sunny, no rainwater flows in, and when it rains, rainwater flows into the discrimination port 14.

[0034] A discrimination chamber 15 is fixed inside the box body 1 and at the bottom of the discrimination port 14. A float 151 is accommodated inside the discrimination chamber 15. The float 151 in this embodiment is configured to be square or round. While facilitating molding, the square shape can be conveniently positioned at the bottom of the discrimination chamber 15 when it is not affected by buoyancy, while the round shape can further increase the contact surface with rainwater and improve the lifting stability.

[0035] A cable through hole is provided at the bottom of the discrimination chamber 15 for the cable 17 to pass through. The bottom of the float 151 is connected to the rotating flap door 16 through the cable 17 passing through the cable through hole. At the same time, the discrimination rainwater entering the discrimination chamber 15 can also be slowly discharged into the box body 1 through the cable through hole.

[0036] like Figure 1 As shown, a rotating flap door 16 is hinged inside the box body 1 and located at the bottom of the discrimination chamber 15. The end of the rotating flap door 16 close to the rainwater outlet 13 is connected to the float 151 through a cable 17. The rotating flap door 16 opens and closes the sewage outlet 12 and the rainwater outlet 13 according to the water inlet condition of the discrimination port 14.

[0037] In this embodiment, the bottom of the rotating flap door 16 is hinged between the sewage outlet 12 and the rainwater outlet 13, and the end of the rotating flap door 16 close to the sewage outlet 12 is connected to a sewage flap door 161 adapted to the sewage outlet 12, and the end of the rotating flap door 16 close to the rainwater outlet 13 is connected to a rainwater flap door 162 adapted to the rainwater outlet 13. When the rotating flap door 16 is rotated to different angles, the sewage outlet 12 and the rainwater outlet 13 are opened and closed respectively; for example, Figure 3As shown, when the rotating flap door 16 rotates to the position where the rainwater flap door 162 is flush with the rainwater outlet 13, the rainwater outlet 13 is closed and the sewage outlet 12 is opened, and the water inside the box body 1 can only be discharged through the sewage outlet 12 but not through the rainwater outlet 13; Figure 4 As shown, when the rotating flap door 16 rotates to the position where the sewage flap door 161 is flush with the sewage outlet 12, the sewage outlet 12 is closed and the rainwater outlet 13 is opened, and the water inside the box body 1 can only be discharged through the rainwater outlet 13 but not through the sewage outlet 12.

[0038] A counterweight 163 is fixedly connected to the top of the rain flap door 162 to help the flap door 162 rotate to the upper side in a natural state. Figure 3 When the middle rainwater flap door 162 is flush with the rainwater outlet 13, the rainwater outlet 13 is closed, so that the sewage entering the interior of the box body 1 when it is not raining can be discharged through the sewage outlet 12. Preferably, the counterweight block 163 is set to be hemispherical to reduce the risk of unexpected collision damage that may occur during the lifting process. At the same time, it is necessary to meet the requirement that the buoyancy of the float 151 when it floats inside the discrimination chamber 15 is greater than the gravity of the counterweight block 163, so that when it rains, the buoyancy of the float 151 when it floats inside the discrimination chamber 15 can pull up the counterweight block 163 to open the rainwater outlet.

[0039] The specific working process of this embodiment is as follows:

[0040] In the initial state, if Figure 2 As shown, at this time, the sewage enters the box body 1 through the mixed flow port 11, and then is discharged into the sewage pipe network through the sewage port 12.

[0041] At the beginning of the rainfall, Figure 3 As shown, although rainwater enters the discrimination port 14 and flows into the discrimination chamber 15, the buoyancy of the water is not enough to float the float, so the rainwater port 13 remains closed, and the rainwater at the initial stage of rainfall is discharged into the sewage network through the sewage port 12, realizing the initial rainwater abandonment;

[0042] During rainfall, Figure 4 As shown, at this time, rainwater enters the discrimination chamber 15 from the discrimination port 14. As the amount of rainwater in the discrimination chamber 15 increases gradually, when the internal rainwater reaches a preset level, the float 151 floats up and the rainwater flap door 162 is pulled up by the cable 17. The flap door 16 is rotated clockwise to open the rainwater port 13 until it is rotated to close the sewage port 12. At this time, the water in the box body 1 is discharged through the rainwater port 13.

[0043] After the rain stops, Figure 5As shown, no discrimination rainwater enters the discrimination chamber 15, and the discrimination rainwater in the discrimination chamber 15 slowly flows out from the cable through hole to the inside of the box body 1, and the float slowly descends until it returns to the initial state, and finally the rainwater outlet 13 is closed and the sewage outlet 12 is opened. At this time, if sewage enters the mixed flow outlet 11, it will be discharged from the sewage outlet 12.

[0044] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
