[0002] In the prior art, a rainwater-sewage diversion device is often used to achieve the diversion of rainwater and sewage, so that sewage can enter the sewage pipe network on sunny days, and rainwater can enter the rainwater pipe network on rainy days.

[0003] Existing rainwater and sewage diversion devices often use the large flow of rainwater caused by rainfall as a judgment condition to close the sewage outlet and open the rainwater outlet, so that the rainwater is discharged into the rainwater pipe network through the rainwater outlet during rainfall. On the one hand, the rainfall process is a relatively complex and uncontrollable process. The existing rainwater and sewage diversion devices are not suitable for rainwater and sewage diversion work during rainfall with small flow rate. The rainwater outlet cannot be completely opened and the sewage outlet closed during small flow rate rain, thereby reducing the rainwater and sewage diversion efficiency. On the other hand, the float and cover body used to judge the flow rate will inevitably participate in the drainage and sewage discharge process. After long-term use, the judgment accuracy will be reduced, affecting the rainwater and sewage diversion efficiency.

[0026] [First embodiment]

[0027] like Figure 1-3The figure shows a rainwater-sewage diversion determination device provided by the first embodiment of the utility model, comprising a shell 1, on which a mixing port 11, a discrimination port 12, a sewage port 13 and a rainwater port 14 connected to the interior of the shell 1 are respectively opened, rainwater, sewage and a mixture of rainwater and sewage can flow into the interior of the shell 1 through the mixing port 11, a discrimination chamber 2 is arranged inside the shell 1, and the discrimination chamber 2 is connected to the discrimination port 12 and the interior of the shell 1. When it rains, a large amount of rainwater flows into the interior of the shell 1 through the mixing port 11, while a small amount of rainwater enters the discrimination chamber 2 through the discrimination port 12. When there is no rainfall, the sewage is discharged through the sewage port 13. Discrimination components connected to each other are arranged inside the shell 1 and the discrimination chamber 2. The discrimination component can automatically control the opening and closing of the sewage port 13 according to the liquid level position inside the discrimination chamber 2. When the discrimination chamber 2 determines that it is currently raining, the sewage port 13 is closed, and the rainwater is discharged through the rainwater port 14.

[0028] In this embodiment, the discrimination port 12 is arranged at a higher position than the mixing port 11 so as to distinguish the two. When it rains, a small amount of rainwater enters the discrimination chamber 2 through the discrimination port 12, and when it is sunny, sewage enters the shell through the mixing port 11. When it rains, a large amount of rainwater and sewage mixture enters the shell 1 through the mixing port 11; the rainwater port 14 is arranged at a higher position than the sewage port 13. After the rainwater is discharged to the rainwater pipe network through the rainwater port 14, the bottom sediment can be discharged together with the sewage through the sewage port 13.

[0029] In this embodiment, on the one hand, by placing the discrimination component part inside the discrimination chamber, the discrimination piece inside the discrimination chamber only contacts rainwater and avoids contact with sewage as much as possible, thereby further improving the applicability and cleanliness of the discrimination piece, extending its service life, and improving the discrimination efficiency. On the other hand, by placing the discrimination component part inside the discrimination chamber, the discrimination piece inside the discrimination chamber can float with only a small flow of rainwater, thereby driving the sewage outlet to close and the rainwater outlet to open, and the rainwater and sewage diversion effect can be effectively achieved even in small-flow rainfall weather, thereby improving the rainwater and sewage diversion efficiency.

[0030] like Figure 1-3As shown, the discrimination chamber 2 in this embodiment includes a discrimination shell 21, and the discrimination shell 21 includes a discrimination shell 211 and a top discrimination cover 212. The discrimination shell 211 is fixed to the inner wall of the shell 1, and the discrimination cover 212 is detachably installed on the top of the discrimination shell 211, so as to facilitate the loading and unloading of the discrimination components inside the discrimination chamber 2. A discrimination hole 213 connected to the shell 1 is opened at the bottom of the discrimination shell 211. Rainwater that has been discriminated inside the discrimination chamber 2 can gradually enter the shell 1 through the discrimination hole 213 and finally be discharged. The aperture size of the discrimination hole 213 determines the speed at which the liquid level inside the discrimination chamber 2 drops. The larger the aperture of the discrimination hole 213, the faster the water flow rate from the inside of the discrimination chamber 2 to the outside, and thus the faster the sewage outlet 13 opens. Therefore, the aperture size of the discrimination hole 213 can be determined according to the actual sewage discharge demand to achieve different opening and closing speed controls of the sewage outlet 13.

[0031] In this embodiment, the discrimination component includes a discrimination member 22 located inside the discrimination chamber 2, the discrimination member 22 is connected to the cover member 24 through the connecting member 23 through the driving pulley 28, the driving pulley 28 is fixed inside the discrimination chamber 2, the cover member 24 is located inside the shell 1 and outside the discrimination chamber 2, the cover member 24 is hinged to the inner wall of the shell 1 through the hinge 25, when the discrimination member 22 rises synchronously with the liquid level in the discrimination chamber 2, the cover member 24 is loosened through the connecting member 23 through the driving pulley 28, and the cover member 24 gradually descends under the action of its own gravity and finally closes the sewage outlet 13, on the contrary, when the discrimination member 22 descends synchronously with the liquid level in the discrimination chamber 2, the cover member 24 is tightened through the connecting member 23 through the driving pulley 28, and the cover member 24 gradually rises and gradually separates from the sewage outlet 13 and finally opens the sewage outlet 13.

[0032] Preferably, in this embodiment, the discriminating element 22 uses a discriminating weight that can rise and fall synchronously with the liquid level inside the discriminating chamber 2, so that the total mass of the discriminating weight can be adjusted to meet different drainage requirements.

[0033] In this embodiment, the connecting member 23 is a flexible connecting member so as to stabilize the process of tightening the cover member 24 when the discriminating member 22 rises and falls synchronously with the liquid level inside the discriminating chamber 2 .

[0034] like Figure 2-3As shown, the cover member 24 in this embodiment includes a sealing ball 241 and a sealing plate 242 fixed to the outer edge of the sealing ball 24. The sealing ball 241 and the sealing plate 242 match the aperture of the sewage outlet 13. Specifically, the sealing ball 241 can be placed inside the sewage outlet 13, and the sealing plate 242 fits with the sewage outlet 13 to achieve a sealing effect when the sewage outlet 13 is closed. The purpose of this arrangement is also to facilitate the separation of the sealing ball 24 from the sewage outlet 13 when the sewage outlet 13 is opened. In order to further improve the sealing effect, sealing rings can be respectively provided on the bottom surface of the sealing plate 242 and the top surface of the sewage outlet 13, that is, on the fitting surfaces of the two. The sealing rings can be made of flexible rubber material to improve the sealing effect while achieving flexible contact.

[0035] In order to ensure the free lifting effect of the discrimination member 22 and avoid the discrimination member 22 being tightly attached to the inner wall of the discrimination chamber 2 due to the pulling of the connecting member 23, a positioning part 26 is extended from the inside of the discrimination chamber 2, and a positioning pulley 261 is hinged at the end of the positioning part 26. The connecting member 23 is wrapped around the outer edge of the positioning pulley 261. Through the action of the positioning pulley 261, it can be ensured that the discrimination member 22 is always located in the inner center of the discrimination chamber 2 during lifting and lowering to achieve free lifting.

[0036] A hinged portion 27 is provided protruding from the inside of the shell 1, and the hinged member 25 is hinged to the hinged portion 27 by a pin 271, so that the cover member 24 can rotate or swing around the hinged position where the pin 271 is located when the connection member 23 is tightened or relaxed; therefore, correspondingly, an extension portion 131 is provided on the inner wall of the shell 1 protruding inwardly at the position corresponding to the sewage outlet 13, and the extension portion 131 is arranged to be inclined to match the movement trajectory of the cover member 24, thereby further ensuring that when the sewage outlet 13 is opened and closed, the sewage outlet 13 can fit more perfectly with the cover member 24.

[0037] like Figure 2 As shown, on a sunny day (not raining), the device is in a non-working state, and the discrimination member 22 falls to the bottom of the discrimination chamber 2 in the shell 1 due to the influence of gravity. At the same time, the discrimination member 22 drives the connected connecting member 23 to move through the driving pulley 28, and drives the cover member 24 to rotate or swing upward around the hinge position where the pin shaft 271 is located. At this time, the sewage outlet 13 is opened, and the sewage from the residential area and the industrial area enters the interior of the shell 1 from the mixed flow outlet 11 of the shell 1. Because the height of the rainwater outlet 14 is higher than the sewage outlet 13, the water in the mixed flow outlet 11 flows to the sewage outlet 13 for discharge.

[0038] like Figure 3As shown, in the rainy state, the device is in working state, and a small amount of rainwater will enter the discrimination chamber 2 through the discrimination port 12. The liquid level in the discrimination chamber 2 continues to rise, driving the discrimination member 22 to rise synchronously. At the same time, the cover member 24 is no longer restricted by the tension of the connecting member 23 on the discrimination member 22. The cover member 24 is rotated or swung downward at the hinged position where the pin 271 is located to seal and close the sewage outlet 13. At this time, the rainwater entering the shell 1 from the mixing port 11 will flow to the rainwater outlet 14.

[0039] When the rainfall ends, the discrimination hole 213 in the discrimination chamber 2 slowly flows out the internal rainwater into the shell 1, and the discrimination member 22 will drop synchronously with the drop of the water level in the discrimination chamber 2, and synchronously drive the other end cover member 24 to move upward through the connecting member 23, and the sewage outlet 13 is opened, and the work is completed.

[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.
