[0040] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0041] The first aspect embodiment of the present application proposes a splitting system 10, which can realize the splitting operation of rainwater and sewage and guarantee the rainwater and sewage treatment effect. The splitting system 10 of the present application embodiment will be introduced below with reference to Figures 1 to 5 Specifically, the splitting system 10 comprises a well body 100, a splitting piece 200 and a limiting part 300.

[0042] Figure 1 ​, the well body 100 is used for rainwater and sewage transfer. The well body 100 defines a cavity 110, which can be cylindrical. The well body 100 includes a water inlet 120, a first water outlet 130, and a second water outlet 140. Referring to Figure 1 In the orientation, the left side opening of the well body 100 can be the water inlet 120, the upper side opening can be the first water outlet 130, and the lower side opening can be the second water outlet 140. It can be understood that the water inlet 120, the first water outlet 130, and the second water outlet 140 are all in communication with the cavity 110 and are arranged at intervals from each other. Rainwater and sewage can enter the cavity 110 through the water inlet 120 and be discharged through the first water outlet 130 or the second water outlet 140.

[0043] It can be understood that the specific discharge area of the first water outlet 130 and the second water outlet 140 can be determined according to actual conditions. In the embodiment of the application, the first water outlet 130 is connected to a natural water body through a first drain pipe, and the second water outlet 140 is connected to a sewage treatment plant through a second drain pipe. That is, when the water quality flowing into the cavity 110 is good, the water body can be directly discharged into a natural water body (river, lake, or ocean); when the water quality flowing into the cavity 110 is poor, the water body can be discharged into a sewage treatment plant for purification treatment.

[0044] Referring to Figures 1 to 5 , the shunt 200 can rotate relative to the well body 100 to shunt rainwater and sewage. Specifically, the shunt 200 can be arranged in the cavity 110 and can rotate relative to the well body 100 to a first rotation position and a second rotation position. The specific rotation direction of the shunt 200 can be determined according to actual conditions. When in the first rotation position, the shunt 200 can block the water inlet 120 and the second water outlet 140, and the water inlet 120 is connected to the first water outlet 130, that is, the water body can enter the cavity 110 through the water inlet 120 and be discharged through the first water outlet 130. When in the second rotation position, the shunt 200 can block the water inlet 120 and the first water outlet 130, and the water inlet 120 is connected to the second water outlet 140, that is, the water body can enter the cavity 110 through the water inlet 120 and be discharged through the second water outlet 140. It can be understood that the shunt can be a wall or a hard plate body.

[0045] Referring to Figure 1 , the limiting part 300 is used for limiting the shunt 200. The limiting part 300 can be located in the cavity 110 and connected to the well body 100. The limiting part 300 can be detachably connected to the shunt 200. Specifically, when the limiting part 300 is connected to the shunt 200, because the limiting part 300 is connected to the well body 100, the shunt 200 can be inhibited from rotating relative to the well body 100; when the limiting part 300 is separated from the shunt 200, the shunt 200 can normally rotate relative to the well body 100 to change the rotation position.

[0046] In the technical scheme of the utility model, the shunt system 10 includes well body 100 and shunt piece 200. Well body 100 defines a cavity 110, and well body 100 includes a water inlet 120, a first water outlet 130 and a second water outlet 140 that communicate with the cavity 110. In the prior art, a combined drainage system is used to collect and transport rainwater and sewage at the same time, which can cause untreated sewage to be directly discharged into natural water bodies, impairing the self-purification ability of the natural water bodies and causing rainwater waste. The shunt piece 200 of the present scheme is located in the cavity 110, and the shunt piece 200 is configured to be rotatable to a first rotational position and a second rotational position relative to the well body 100. In the first rotational position, the water inlet 120 communicates with the first water outlet 130, and the shunt piece 200 blocks the water inlet 120 and the second water outlet 140, i.e. the water in the well body 100 can be discharged through the first water outlet 130. In the second rotational position, the water inlet 120 communicates with the second water outlet 140, and the shunt piece 200 blocks the water inlet 120 and the first water outlet 130, i.e. the water in the well body 100 can be discharged through the second water outlet 140. Therefore, the present scheme can use the shunt system 10 to achieve rainwater and sewage shunting, so that rainwater and sewage flow to different areas, effectively collecting and treating rainwater and sewage, preventing rainwater and sewage from mixing and flowing into natural water bodies, and protecting the ecological system of the natural water bodies.

[0047] In addition, the shunt system 10 further includes a limiting part 300 located in the cavity 110 of the well body 100 and connected to the well body 100. The limiting part 300 is separably connected to the shunt piece 200 to inhibit the rotation of the shunt piece 200 relative to the well body 100. Therefore, the limiting part 300 can effectively improve the stability of the rotation shunting of the shunt piece 200, realize the continuous and reliable operation of the shunt system 10, and ensure the treatment effect of rainwater and sewage.

[0048] Referring to Figure 1 and Figure 2 , the specific shunting arrangement of the shunt piece 200 will be described below. In some embodiments, the shunt piece 200 divides the cavity 110 into a first cavity 111 and a second cavity 112, i.e. the first cavity 111 is not in communication with the second cavity 112. When in the first rotational position, the first cavity 111 communicates the water inlet 120 and the first water outlet 130, so that the water can only be discharged through the first water outlet 130. When in the second rotational position, the second cavity 112 communicates the water inlet 120 and the second water outlet 140, so that the water can only be discharged through the second water outlet 140. The shunt piece 200 of the present scheme can divide the cavity 110 into the first cavity 111 and the second cavity 112 that are independent of each other, effectively collect and treat rainwater and sewage, ensure the accuracy and stability of water shunting, and protect the ecological system of the natural water bodies.

[0049] It should be noted that during the switching of the rotating position of the flow distributor 200, the cavity volumes of the first cavity 111 and the second cavity 112 are constant, but the cavity positions of the first cavity 111 and the second cavity 112 are changed. In some embodiments, the cavity volume of the first cavity 111 can be equal to that of the second cavity 112. In other embodiments, the cavity volume of the first cavity 111 can be smaller or larger than that of the second cavity 112. The specific settings of the first cavity 111 and the second cavity 112 can be determined according to actual conditions, and some embodiments of the present application are described by taking the example that the volume of the first cavity 111 is equal to that of the second cavity 112.

[0050] Referring to Figure 3 and Figure 5 , the specific settings of the limiting part 300 are described below. In some embodiments, the limiting part 300 has a first position and a second position. When in the first position, the limiting part 300 can be connected to the flow distributor 200, i.e., it can inhibit the rotation of the flow distributor 200 relative to the well body 100, thereby ensuring the accuracy and stability of the flow distribution operation. When in the second position, the limiting part 300 can be spaced from the flow distributor 200, i.e., the flow distributor 200 can normally rotate relative to the well body 100. Specifically, in the horizontal direction, the limiting part 300 can move away from the cavity 110, thereby switching from the first position to the second position. The position switching operation of the limiting part 300 of the present scheme is convenient and fast, which can stabilize the flow distributor 200 at the target rotating position and ensure the stability of the water flow distribution.

[0051] It should be noted that in some embodiments, the well body 100 can be provided with a guide groove, and the limiting part 300 can move in the guide groove, thereby ensuring the accuracy and stability of the movement of the limiting part 300. In other embodiments, the flow distribution system 10 can be provided with a power assembly to drive the movement of the limiting part 300. Specifically, motor drive or hydraulic drive can be adopted, and the specific driving settings of the limiting part 300 can be determined according to actual conditions. In other embodiments, when in the second position, the limiting part 300 can be withdrawn into the well body 100 to avoid interfering with the normal rotation of the flow distributor 200.

[0052] Referring to Figure 3 and Figure 5, the specific structure of the limiting part 300 is introduced. In some embodiments, the limiting part 300 includes a first limiting block 310 and a second limiting block 320 arranged oppositely. The structure of the second limiting block 320 can be the same as or different from that of the first limiting block 310. The embodiments of the present application take the case where the second limiting block 320 has the same structure as the first limiting block 310 as an example for illustration. When in the first position, the first limiting block 310 and the second limiting block 320 can be connected to the two side walls 210 of the flow distributor 200 along the thickness direction of the flow distributor 200 respectively, so as to inhibit the rotation of the flow distributor 200 relative to the well body 100. Further, the first limiting block 310 and the second limiting block 320 can abut against the side walls 210 of the flow distributor 200. The scheme can guarantee the stability of the limiting of the limiting part 300, and prevent the water flowing in through the water inlet 120 from impacting the flow distributor 200 in multiple directions, so as to cause the flow distributor 200 to change position greatly and cause the flow distribution to be inaccurate.

[0053] With reference to Figure 4 and Figure 5 , the relative arrangement positions of the first limiting block 310 and the second limiting block 320 are introduced below. In some embodiments, along the vertical direction, the first limiting block 310 can be arranged at the same height as the second limiting block 320. In other embodiments, along the vertical direction, the first limiting block 310 can be spaced from the second limiting block 320. Specifically, along the vertical direction, the first limiting block 310 can be arranged above the second limiting block 320 or below the second limiting block 320. The embodiments of the present application take the case where the first limiting block 310 and the second limiting block 320 are arranged at the same height as an example for illustration. The scheme can further improve the stability of the limiting of the limiting part 300 on the flow distributor 200, and thus guarantee the reliability of the flow distribution operation.

[0054] With reference to Figures 1 to 5 , the specific arrangement position of the limiting part 300 is introduced below. In some embodiments, when in the first rotation position, the limiting part 300 can be connected to the flow distributor 200 to stop rotation, i.e., the limiting part 300 can be arranged at the first rotation position. In other embodiments, when in the second rotation position, the limiting part 300 can be connected to the flow distributor 200 to stop rotation, i.e., the limiting part 300 can be arranged at the second rotation position. The embodiments of the present application take the case where the limiting part 300 is arranged at both the first rotation position and the second rotation position as an example for illustration. The scheme can limit and stop the rotation of the flow distributor 200 by the limiting part 300 no matter whether the flow distributor 200 is in the first rotation position or the second rotation position, i.e., the stability of the flow distribution can be improved effectively.

[0055] With reference to Figures 1 to 5 , in some embodiments, the well body 100 includes a third water outlet 150, which is in communication with the cavity 110. With reference to Figure 3The third water outlet 150 can be a water outlet on the right side of the well body 100, and is arranged at intervals from the water inlet 120, the first water outlet 130, and the second water outlet 140. The specific discharge area of the third water outlet 150 can be determined according to actual conditions. In the embodiment of the present application, the third water outlet 150 is connected to the storage tank through a third drain pipe, that is, when the water flowing into the cavity 110 is between high-quality and poor-quality (sewage), it can be discharged to the storage tank for treatment. The present scheme can meet the water diversion requirements in various situations, and further improve the effect of water quality-based treatment.

[0056] With reference to Figure 3 The shunt 200 can be rotated to a third rotation position relative to the well body 100. When in the third rotation position, the water inlet 120 is connected to the third water outlet 150. In the vertical direction, the third water outlet 150 is located below the first water outlet 130 and the second water outlet 140, that is, the water can be discharged from the third water outlet 150 before the first water outlet 130 and the second water outlet 140, and the water diversion operation is convenient and fast.

[0057] With reference to Figure 4 and Figure 5 In some embodiments, the limiting portion 300 includes a third limiting block 330 and a fourth limiting block 340 arranged opposite to each other. The structure of the third limiting block 330 can be the same as or different from that of the fourth limiting block 340. In the embodiment of the present application, the third limiting block 330 and the fourth limiting block 340 have the same structure. When in the first position, the third limiting block 330 and the fourth limiting block 340 are respectively connected to the two side walls 210 of the shunt 200 along the thickness direction thereof, so as to inhibit the rotation of the shunt 200 relative to the well body 100. Further, the third limiting block 330 and the fourth limiting block 340 can abut against the two side walls 210 of the shunt 200. The present scheme can further improve the stability of the limiting of the limiting portion 300, prevent the water flowing into the water inlet 120 from impacting the shunt 200 in multiple directions, and cause the shunt 200 to change position greatly, resulting in inaccurate shunting.

[0058] With reference to Figures 1 to 3 The specific rotation process of the shunt 200 will be introduced below. In some embodiments, the shunt system 10 includes a base 400 and a driving portion connected to each other. The base 400 can be arranged at the bottom of the well body 100, and the shunt 200 can be connected to the driving portion. The driving portion has a rotation axis 500 parallel to the vertical direction, and is used to drive the shunt 200 to rotate around the rotation axis 500, so as to switch between the first rotation position and the second rotation position. The present scheme can guarantee the stability and accuracy of the rotation of the shunt 200, and guarantee the shunting effect.

[0059] The utility model discloses second aspect embodiment proposes a kind of drainage systems 1, drainage systems 1 includes the shunt system 10 of above-mentioned embodiment, the scheme can realize rainwater and sewage shunt, make rainwater and sewage flow to different area, effectively collect and handle rainwater and sewage, prevent rainwater and sewage mixed flow to natural water body, protect the ecosystem of natural water body.Limiting portion 300 can effectively promote the stability of shunt piece 200 shunt, realize the continuous reliable operation of shunt system 10, guarantee the treatment effect of rainwater and sewage.

[0060] With reference to Figures 1 to 5 In some embodiments, the drainage system 1 further includes a pre-settling tank 20, a combined sewer 30, and a monitoring module 40. The combined sewer 30 can be connected to the pre-settling tank 20 and the water inlet 120, i.e., the water in the pre-settling tank 20 can flow to the water inlet 120 through the combined sewer 30, and then enter the cavity 110 to realize shunt. The monitoring module 40 is used to monitor the water quality of the water in the combined sewer 30, and then confirm the discharge direction of the water in the combined sewer 30, to improve the accuracy of shunt. In other embodiments, the drainage system 1 further includes a control module 50, which can receive the water quality information sensed by the monitoring module 40, and control the rotation of the shunt piece 200 and the extension and contraction movement of the limiting portion 300.

[0061] With reference to Figures 1 to 5 The following describes the specific treatment process of the drainage system 1 of some embodiments of the present application. When in the middle of rainfall, the water in the combined sewer 30 is mainly rainwater (with better water quality), when the monitoring module 40 monitors that the water quality meets the target requirement, the control module 50 can control the shunt piece 200 to rotate to the first rotation position, and the limiting portion 300 can limit the shunt piece 200, i.e., the water in the combined sewer 30 can be discharged to the natural water body through the first water outlet 130, to realize rainwater collection and avoid polluting the water body. When in sunny weather, the water in the combined sewer 30 is mainly sewage, and the shunt piece 200 can rotate to the second rotation position (default state), i.e., the water in the combined sewer 30 can be discharged to the sewage treatment plant for purification treatment through the second water outlet 140, to reduce pollution to the natural water body. When in the early and late stages of rainfall, the water in the combined sewer 30 is mainly a mixture of rainwater and sewage, with water quality better than sewage but lower than rainwater, and the shunt piece 200 can rotate to the third rotation position, i.e., the water in the combined sewer 30 can be discharged to the storage tank for treatment through the third water outlet 150. The scheme can realize accurate rainwater and sewage shunt in areas where rainwater and sewage shunt cannot be implemented in underground space, the water quality discharge requirement of the end natural water body is high, and the scale of the sewage treatment plant is insufficient, without affecting the environmental quality of the end natural water body and without increasing the treatment load of the sewage treatment plant.

[0062] It should be noted that the control module 50 can preset the water diversion scheduling scheme in advance, including the water quality determination standard corresponding to the rotation position and rotation direction of the diversion device 200 and the extension movement of the limiting part 300 under the conditions of sunny day, beginning and ending period of rainfall, and middle period of rainfall.
