[0002] In the actual use process of the existing rain and sewage diversion device, it is necessary to access the discrimination water, and determine whether the water entering the device is rainwater or sewage through the discrimination water, so as to correspondingly realize the opening and closing of the sewage outlet. The accuracy rate of discrimination by this rain and sewage diversion discrimination method is relatively high, but it is necessary to keep a certain continuous flow of the discrimination water. Therefore, there are restrictions on the on-site installation conditions, and it cannot be effectively applied to the actual application occasions where it is impossible to find a suitable discrimination water access. Therefore, it is necessary to provide a device that can also carry out rain and sewage diversion for the building mixing pipe without discrimination water. Summary of the Invention

[0031] [First Embodiment]

[0032] AsFigures 1-9 The figure shows a buffer-type intelligent rain and sewage diversion device provided by the first embodiment of the present invention. As Figures 1-3 shown, it includes a housing 1. The interior of the housing 1 is divided into a buffer chamber 11, a discrimination chamber 12, and a discharge chamber 13 by a first partition 14 and a second partition 15. As Figure 3 shown, in this embodiment, the first partition 14 and the second partition 15 are arranged in a T shape. The discrimination chamber 12 and the discharge chamber 13 are arranged on the same side of the first partition 14 and on both sides of the second partition 15.

[0033] Preferably, in this embodiment, the heights of the first partition 14 and the second partition 15 are less than the height of the housing 1, and the height of the first partition 14 is greater than the height of the second partition 15, so that in rainy days, a large flow of rainwater can directly cross the first partition 14 and enter the interior of the discrimination chamber 12 from the buffer chamber 11, and enter the interior of the discharge chamber 13 from the discrimination chamber 12 by crossing the second partition 15.

[0034] A first through hole 141 communicating the buffer chamber 11 and the discrimination chamber 12 is provided inside the first partition 14, and a second through hole 151 communicating the discrimination chamber 12 and the discharge chamber 13 is provided inside the second partition 15, so that the sewage entering the buffer chamber 11 on sunny days can first flow into the discrimination chamber 12 through the first through hole 141, and then flow from the discrimination chamber 12 into the discharge chamber 13 through the second through hole 151.

[0035] A mixed-flow port 111 communicating with the buffer chamber 11, a sewage discharge port 131 and a rainwater discharge port 132 communicating with the discharge chamber 13 are respectively provided on the housing 1, so that both rainwater and sewage can enter the interior of the buffer chamber 11 through the mixed-flow port 111. On sunny days, the sewage can be discharged into the sewage network through the sewage discharge port 131 in the discharge chamber 13. On rainy days, the sewage discharge port 131 is closed, and the rainwater can be discharged into the rainwater network through the rainwater discharge port 132 in the discharge chamber 13.

[0036] As Figure 1As shown in the figure, a lever mechanism 2 capable of controlling the opening and closing of the sewage discharge port 131 is provided inside the discrimination chamber 12 and the discharge chamber 13. The lever mechanism 2 includes a connecting rod 21 hinged to the top of the second partition 15. One end of the connecting rod 21 is connected to the float 22 inside the discrimination chamber 12, and the other end of the connecting rod 21 is connected to the cover body 23 inside the discharge chamber 13. When the liquid level inside the discrimination chamber 12 drives the float 22 to rise, the cover body 23 at the other end is driven to descend through the connecting rod 21 to close the sewage discharge port 131. As a preference in this embodiment, the lever mechanism 2 further includes a limiting device 24. One end of the limiting device 24 is fixedly connected to the second partition 15, and the other end is sleeved on the top of the cover body 23. The limiting device 24 is used to ensure that the cover body 23 realizes the lifting action in the vertical direction. The float 22 is preferably set as a sphere, which is convenient for molding and can evenly bear the buoyancy. To further ensure the sealing effect when the sewage discharge port 131 is closed, the outer edge size of the cover body 23 needs to be adapted to the inner diameter size of the sewage discharge port 131.

[0037] The improvement of this embodiment compared with the prior art lies in that: a buffer chamber volume adjustment component is provided inside the buffer chamber 11. By setting the buffer chamber volume adjustment component, the volume of the buffer chamber can be adjusted as needed, so as to correspondingly adjust the volume of the buffer chamber according to different sewage discharge amounts accessed by the mixing pipe, so as to meet the rainwater and sewage separation requirements in different situations.

[0038] Specifically, as Figure 3 shown, in this embodiment, the buffer chamber volume adjustment component includes an installation groove 112 provided on the inner wall of the buffer chamber 11 and a plug-in board 113 installed inside the installation groove 112. The outer edge of the plug-in board 113 is in plug-in fit with the installation groove 112. By inserting the plug-in board 113 into the installation groove 112 at different positions, the buffer chamber 11 can be divided into different volumes, so as to correspondingly adjust the volume of the buffer chamber according to different sewage discharge amounts accessed by the mixing pipe, so as to meet the rainwater and sewage separation requirements in different situations. Correspondingly, multiple groups of installation grooves 112 are arranged in pairs on the inner wall of the buffer chamber 11.

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

[0040] Taking the application of this embodiment to the rainwater and sewage diversion of the building balcony vertical pipe as an example, the mixing connection of the building balcony rainwater downpipe is mostly the discharge of washing sewage from the washing machine. Therefore, it can be determined that the water flowing into the mixing pipe is rainwater on rainy days and sewage on sunny days.

[0041] On sunny days, the sewage enters the buffer chamber 11 through the mixing port 111. The sewage in the buffer chamber 11 enters the inside of the discrimination chamber 12 through the first through hole 141, and then flows from the discrimination chamber 12 into the inside of the discharge chamber 13 through the second through hole 151 and is discharged into the sewage pipe network through the sewage discharge port 131 (at this time, as Figure 4as shown); if the water inflow rate at the mixed flow port 111 is greater than the discharge rate at the sewage discharge port 131, the liquid level in the buffer chamber 11 will continue to rise (at this time as Figure 5 shown); since the drainage is not continuous for a long time, after the sewage discharge stops, the liquid level inside the buffer chamber 11 will drop as the sewage is discharged until it is completely emptied (at this time as Figure 6 shown); due to different on-site situations, the number of washing machines connected to the mixed flow port 11 is also different. According to the actual on-site situation, the internal volume of the buffer chamber 11 can be adjusted by whether to install the plug-in board 113 and selecting the position of the plug-in board 113.

[0042] On rainy days, rainwater enters the buffer chamber 11 through the mixed flow port 111. The initial rainwater has a high pollutant content and can be directly discharged into the sewage pipe network through the sewage discharge port 131 (at this time as Figure 7 shown); as the rainfall continues, the liquid level inside the buffer chamber 11 rises until it crosses the first baffle 14 and enters the discrimination chamber 12. The water inflow rate of the discrimination chamber 12 increases and the liquid level rises accordingly. The float 22 rises due to buoyancy and presses down the cover body 23 through the connecting rod 21 to close the sewage discharge port (at this time as Figure 8 shown); the subsequent rainwater that enters will pass through the rain discharge port 132 and enter the rainwater pipe network (at this time as Figure 9 shown). At this time, the installation selection of the plug-in board 113 also has the function of adjusting the initial rainwater rejection flow rate.

[0043] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms. Therefore, in any regard, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
