[0001] The utility model relates to the technical field of rainwater and sewage diversion devices, and in particular to a rain-sensitive self-driven rainwater and sewage diversion device. Background Art

[0002] A patent application with application number CN2018209752407 discloses an intelligent rainwater and sewage diversion device, which uses whether there is water flowing into the rainwater inlet as the standard for distinguishing the water quality of the rainwater and sewage mixed flow pipe. Once water flows into the rainwater pipe inlet, it is determined that it is raining, the sewage outlet is closed, and the rainwater outlet is opened to collect rainwater; when there is no water flowing into the rainwater pipe inlet, it is determined that sewage is entering, the sewage outlet is opened, and the sewage is discharged from the sewage outlet.

[0003] However, in actual use, the intelligent rainwater and sewage diversion device requires continuous and large amounts of discrimination water as a driving force for closing the sewage outlet flap door, and the flow rate requirement for the discrimination water is relatively high, resulting in limitations in actual use.

[0004] Therefore, there is an urgent need to provide a rain-sensitive self-driven rainwater and sewage diversion device to solve the defects and shortcomings in the above-mentioned prior art. Utility Model Content

[0029] [First embodiment]

[0030] like Figure 1-5 The first embodiment of the utility model is a rain-sensitive self-driven rainwater and sewage diversion device, comprising a box body 1, the outer side of the box body 1 is respectively provided with a mixed flow port 11, a sewage port 12 and a rainwater port 13; in this embodiment, as Figure 1 As shown, the mixed flow port 11 is externally connected to a mixed flow pipe. On sunny days, sewage flows into the mixed flow port 11, and on rainy days, rainwater flows into the mixed flow port 11. The sewage port 12 is externally connected to a sewage pipe network, which is arranged at the bottom of the box body 1 and close to the mixed flow port 11, so that when sewage enters the mixed flow port 11, it is convenient to discharge from this port; the rainwater port 13 is externally connected to a rainwater pipe network, which is arranged on a side of the box body 1 away from the mixed flow port 11. When rainwater enters the mixed flow port 11, it is discharged from this port.

[0031] like Figure 1As shown, a distinguishing opening 14 is provided on the top of the box body 1. Figure 1 As shown, the mixing port 11 and the distinguishing port 14 are arranged on the same side of the box body 1, and the distinguishing port 14 is located at the top of the mixing port 11, with an external rain receiving device or rainwater outlet. When it is sunny, no rainwater flows in, and when it rains, rainwater flows into the distinguishing port 14.

[0032] The box 1 is provided with a discriminating device 15, which opens and closes the sewage outlet 12 according to the water inlet condition of the discriminating port 14; Figure 1 As shown, the discrimination device 15 in this embodiment includes a rotating rod 151, the middle part of the rotating rod 151 is hinged to the inside of the box body 1, one end of the rotating rod 151 is hinged to a connecting rod 152, and the other end of the connecting rod 152 is connected to a flap door 153, and the flap door 153 is set to a shape that matches the sewage outlet 12 so as to facilitate the opening and closing of the sewage outlet 12. In this embodiment, the flap door 153 is set to a hollow structure so as to facilitate receiving the discrimination rainwater flowing into the top discrimination port 14; correspondingly, a flap door emptying port 1531 is opened at the bottom of the flap door 153, and the discrimination rainwater entering the flap door 153 can be slowly discharged through the emptying port 1531.

[0033] like Figure 1 As shown, the other end of the rotating rod 151 is fixedly connected with a counterweight 154, and the mass of the counterweight 154 needs to be set to be greater than the mass of the flap door 153 and less than the sum of the masses of the flap door 153 and the internal preset liquid level rainwater, so that when no rainwater is judged to enter the flap door 153, the counterweight 154 can lift the flap door 153 to a high position due to its own weight, thereby opening the sewage outlet 12, and after the flap door 153 is judged to have reached the preset liquid level, the flap door and the internal judged rainwater The mass exceeds the self-weight of the counterweight 154, so that it falls to a low position and finally closes the sewage outlet 12. As a preferred embodiment of this embodiment, the counterweight 154 can be set to a spherical or hemispherical shape to reduce the risk of unexpected collision damage that may occur during the lifting process.

[0034] The specific working process of this embodiment is as follows:

[0035] In the initial state, if Figure 2 As shown, at this time, neither sewage nor rainwater enters the mixed flow port 11 , and the counterweight block 154 falls due to its own weight, causing the flap door 153 to be lifted to a high position, thereby opening the sewage port 12 .

[0036] When sewage enters the mixing port 11, Figure 3 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.

[0037] At the beginning of the rainfall, Figure 4As shown, at this time, rainwater enters the discrimination port 14 and flows into the flap gate 153, causing the weight ratio on both sides of the rotating rod 151 to change. When the rainwater inside the flap gate 153 reaches a preset liquid level, as the rainwater gradually enters the flap gate 153, the flap gate 153 begins to slowly descend but the sewage outlet 12 is not closed. At this time, rainwater enters the mixing port 11. The pollutant content of the rainwater is relatively high in the initial stage and can be discharged through the sewage outlet 12. Part of the rainwater enters the flap gate to accelerate the descent of the flap gate.

[0038] As the water inside the flap door increases, the flap door gradually drops until the sewage outlet 12 is completely closed. Figure 5 As shown, at this time, the rainwater entering the mixing port 11 will be directly discharged into the rainwater pipe network through the rainwater port 13.

[0039] After the rain stops, when there is no water entering the mixed flow port 11, the rainwater in the flap gate slowly flows out from the flap gate drain port 1531, and the device returns to its initial state. At this time, if sewage enters the mixed flow port 11, it is discharged from the sewage port 12.

[0040] 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.
