[0034] Embodiment 1

[0035] Please refer to 1-4. The embodiment of the present invention provides a flow diversion buffer device, which includes: a well body 1, a dividing part 2 and a first water switch 3, wherein the well body 1 is provided with a water inlet 10 and a water outlet 11;

[0036] The dividing part 2 is arranged in the well body 1, dividing the space in the well body 1 into a first area 20 and a second area 21. The first area 20 is located outside the second area 21. The water inlet 10 and the water outlet 11 are respectively connected to the first area 20. The dividing part 2 is provided with a sewage interception port 22 and a sewage outlet 23. The sewage interception port 22 is connected to the second area 21, and the sewage outlet 23 connects the first area 20 and the second area 21; the first hydraulic switch 3 is arranged at the sewage outlet 23, which is used to control the conduction or closing of the sewage outlet 23. The method of use is as follows: on sunny days, the first water switch 3 is turned on, and the sewage in the upstream pipe of the well body 1 enters the first zone 20 from the water inlet 10, and the domestic sewage of the unit area 5 (such as the combined sewer community) also enters the first zone 20 through the sewage outlet 23, and then flows into the downstream from the water outlet 11; on rainy days, the first water switch 3 is closed, and the domestic sewage of the unit area 5 (such as the combined sewer community) enters the second zone 21 for storage from the sewage interception port 22, and the rainwater in the upstream pipe of the well body 1 enters the first zone 20 from the water inlet 10, and then flows into the downstream from the water outlet 11. This structure can realize the separation of clean and dirty water, effectively avoid the situation where the combined sewer pipe is mixed with sewage on rainy days, and solve the separation of clean and dirty water from the source.

[0037] Furthermore, at least one rainwater inlet 12 is provided on the well body 1. It can be understood that some unit areas 5 have a rainwater inlet 12, and some unit areas 5 have multiple rainwater inlets 12. By connecting the rainwater inlet 12 to the first area 20, multiple rainwater inlets 12 can be connected to the same well body 1. This structure can collect rainwater pipes in the unit area 5 and save installation space.

[0038] See also Figure 1 and Figure 2 In this embodiment, a preferred solution of the dividing part 2 is that the dividing part 2 includes a cylindrical barrel 24 and a cover plate 25 installed on the top of the barrel. The barrel 24 is installed in the well body 1. The barrel 24 and the bottom of the well body 1 form a second zone 21. The outer wall of the barrel 24 and the inner wall of the well body 1 and the bottom of the well form a first zone 20. Both the first zone 20 and the second zone 21 extend in the depth direction. By setting a sewage interception port 22 and a sewage outlet 23 on the barrel 24, the sewage interception port 22 is set at the upper part of the barrel 1, and the sewage outlet 23 is set at the lower part of the barrel 24, so as to ensure that the water cached in the barrel 24 can be emptied into the first zone 20 by gravity flow. If the sewage interception pipe connected to the sewage interception port 22 passes through the well body 1, the pipe needs to be sealed and connected to the well body 1. It can be understood that in this embodiment, the well body 1 can be a newly built well body, or it can be a rainwater well modification port under the rain grate in the unit area 5, and the existing equipment can be used for modification, saving construction time and construction cost.

[0039] It can be understood that if the well body 1 in this embodiment is a cylindrical structure, it should be arranged on the same center line as the cylinder 24 of the dividing part 2, the cylinder 1 is installed at the bottom of the well body, the outer wall of the dividing part 2 and the inner wall and bottom of the well body 1 form a first area 20, and the inner wall of the dividing part 2 and the bottom of the well body form a second area 21. The depth and diameter of the cylinder 1 are designed according to the amount of sewage to be buffered. In addition, in order to discharge the water in the second area 21 cleanly, the sewage outlet 23 is set near the bottom of the well body 1, and the sewage in the second area 21 flows from the sewage outlet 23 into the first area 20 through gravity flow, and the water in the second area 21 can be discharged without the help of other equipment. This structure can save resources.

[0040] In addition, as a preferred solution, the water cached in the second zone 21 can be discharged into the first zone 20 by gravity flow, or by pump discharge or air discharge. The use of gravity flow discharge saves resources, requires no maintenance, and has low cost.

[0041] See also Figure 4 and Figure 5 As another preferred solution of the dividing part 2 in this embodiment, the second area 21 formed by the dividing part 2 is further provided with a diversion part 210, which divides the second area 21 into a buffer area 211 and a diversion area 212. The diversion part 210 is provided with a sewage inlet 215, a sewage interception port 22, and a sewage outlet 23. The sewage inlet 215 connects the buffer area 211 and the diversion area 212. The sewage on sunny days is diverted to the first area 20 through the diversion part 210, and the sewage on rainy days is diverted to the buffer area 211 for temporary storage. The diversion part 21 is arranged near the top of the second area 21, does not affect the storage space of the buffer area 211, and has a simple overall structure and is easy to maintain. In addition, it is conceivable that since the diversion portion 210 is designed to be located near the top of the second zone 21, the water in the buffer zone 211 below the diversion portion 2 will not be able to drain by gravity. At this time, it is necessary to design an emptying device, which is arranged in the buffer zone 211. The emptying device connects the buffer zone 211 and the first zone 20, and is used to drain the water stored in the buffer zone 211 into the first zone 20.

[0042] Furthermore, a drainage pump 4 can be provided in the buffer zone 211 to discharge the sewage in the buffer zone 211 to the first zone 20. The sewage in the buffer zone 211 is lifted to the diversion zone 212 by pumping and then flows into the first zone 20 and discharged downstream. The control of the drainage pump 4 is simple. In addition to the pumping method of this embodiment, the buffer zone can also be emptied by air or gravity, and the specific method can be selected in combination with the actual use environment.

[0043] As a way to implement the second zone 21, the dividing portion 2 in this embodiment includes a cylindrical body 24 and a cover plate 25 installed on the top of the body. The body 24 is installed in the well body 1. The lower edge of the body 24 is located below the water inlet 10 and the water outlet 11 and does not extend to the bottom of the well body 1. The inner wall of the body 24 and part of the wall and bottom of the well body 1 form the second zone 21, which maximizes the use of the space in the well and increases the space of the buffer zone.

[0044] It can be imagined that as another implementation method of the second zone 21, the dividing part 2 in this embodiment includes a cylindrical body 24 and a cover plate 25 installed on the top of the body. The body is installed in the well body 1, and the lower edge of the body 24 extends to the bottom of the well body 1. The inner wall of the body 24 and the bottom of the well body form the second zone 21. Although the space in the buffer zone 211 is small, it is easy to install. The bottom edge of the body 24 can be buckled on the bottom of the well body 1. Compared with the above-mentioned dividing part 2, each has its advantages and disadvantages, which can be selected in combination with the actual usage scenario.

[0045] Furthermore, the diversion part 210 includes a bottom plate 213 and a baffle 214, and the cover plate 25, the baffle 214, the bottom plate 213 and part of the inner wall of the dividing part 2 enclose a diversion area 212, and the sewage inlet 215 is arranged on the baffle 214, wherein the area of ​​the bottom plate 214 is smaller than the cross-sectional area of ​​the cylinder 24 perpendicular to the axial direction, and the baffle 214 and part of the inner part of the dividing part 2 form the peripheral position of the diversion area 212, and the diversion part 210 saves components and installation space by means of the structure of the dividing part 2. Furthermore, the baffle 214 is arc-shaped, and its two ends are connected to the inside of the dividing part 2, so as to make full use of the internal space of the second area 21, increase the space of the buffer zone 211, and increase the sewage buffering capacity.

[0046] Preferably, in this embodiment, the water inlet height of the sewage interception port 22 is higher than the water inlet 10 and the water outlet 11 , so as to ensure that the water flowing out of the sewage interception port 22 can flow into the first area 21 unimpeded.

[0047] As a preferred bottom, the water inlet 10 and the water outlet 11 are arranged relatively flush, which is convenient for prefabrication and reduces water outlet resistance.

[0048] The first hydraulic switch 4 may be one of the following switches: an air bag, an air pillow, a pipe clamp valve or a flexible shut-off device; the embodiment of the present invention is not limited to this, and any switch that can control the conduction of the pipeline may be applicable to the present invention.

[0049] Embodiment 2

[0050] See also Figure 5 As shown, this embodiment 2 provides a drainage system, including:

[0051] In the above-mentioned embodiment 1, a diversion buffer device is provided, wherein the water inlet 10 of the diversion buffer device is connected to an upstream combined sewer pipe, and the water outlet 11 is connected to a downstream combined sewer pipe; the sewage pipe 6 in the unit area 5 is connected to the sewage interception port 22 of the diversion buffer device. The unit area 5 in this embodiment can be a residential house or an office building.

[0052] In summary, the diversion buffer device of the present embodiment is integrated into an integrated structure. On sunny days, the sewage flowing out of the unit area 5 enters the second area 21 from the sewage interception port 22 through the sewage pipe 6, and is discharged from the sewage outlet 23 of the second area 21. On rainy days, the first hydraulic switch 4 of the sewage outlet 23 is closed, and the sewage in the unit area 5 enters the second area 21 from the sewage interception port 22 through the sewage pipe 6 for temporary storage. At this time, rainwater in the upstream pipeline of the well body 1 or the rainwater pipe connected to the well body 1 enters the first area 20 from the water inlet 10, and is discharged to the downstream from the water outlet 11. This structure can achieve that on sunny days, the well body 1 The upstream and downstream pipes all transport sewage, and on rainy days, the upstream and downstream pipes all transport rainwater. The drainage system is based on the existing combined pipe network and only needs to install a diversion buffer device. The diversion buffer device is integrated into the one-piece structure. The second zone 21 extends downward to increase the buffer capacity, maximizes the space savings, and makes full use of the space below the ground. Compared with previous technologies, the renovation cost is low and there is no need to change the existing combined pipe. It is only necessary to set a diversion buffer device before the sewage outlet pipe is connected to the community combined pipe, so there is no need to carry out rainwater and sewage diversion renovation on the combined pipe network in front of the building.

[0053] Those skilled in the art can understand that the control method of the above-mentioned controller is only an example of the use environment of the first embodiment of the present second embodiment, and is not limiting. Those skilled in the art can make adaptive adjustments or deformations to the control method according to actual operating conditions. The present embodiment does not limit this, and it can be understood that it is still within the scope of application and protection of the present invention.

[0054] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to examples, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
