[0002] Rainwater and sewage diversion is to collect rainwater and sewage respectively using independent pipe network systems. Rainwater is discharged into the surrounding pipes, and sewage is sent to the municipal sewage treatment plant. This is also the main mode used in new urban areas. With the increasingly rapid urban development and the gradual increase in population density, the amount of domestic sewage generated has increased, but the initial rainwater volume has not changed. The drainage mode of rainwater and sewage diversion better meets the requirements of modern society. It is generally recommended to adopt rainwater and sewage diversion for newly built urban drainage pipe network systems.

[0003] With the modern development of cities and the upgrading and transformation of old urban areas, rainwater and sewage diversion has become an important part of urban renewal and upgrading of urban quality. In view of the problems existing in the current urban rainwater and sewage diversion transformation, targeted and effective measures need to be taken in many aspects such as design, construction, and management. Ultimately, the rainwater and sewage diversion of the overall urban drainage system can be achieved, thereby reducing the pollution of sewage to the urban ecological environment and improving the overall environmental quality of the city.

[0004] However, at present, when the rainwater is small, the rainwater and sewage diversion device still has the problem that sewage will still be mixed in and directly discharged into the river along with the rainwater, causing pollution and incomplete separation. Content of the Utility Model

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention;

[0023] Please refer to Figures 1 to 4 , in the present invention, an urban rain and sewage pipe network diversion treatment device includes a pre-buried vertical cylinder 1. A protective grille cover 2 is clamped on the top of the pre-buried vertical cylinder 1. A sewage inlet pipe 3 is fixedly connected to the left side of the pre-buried vertical cylinder 1. A sewage discharge pipe 4 and a rainwater discharge pipe 5 are fixedly connected to the right side of the pre-buried vertical cylinder 1. The rainwater discharge pipe 5 is located above the sewage discharge pipe 4. A positioning disk 6 is fixedly connected inside the pre-buried vertical cylinder 1. A through hole 7 is opened inside the positioning disk 6. An I-shaped frame 8 is slidably installed on the positioning disk 6. The bottom end of the I-shaped frame 8 extends to the bottom of the positioning disk 6 and is fixedly connected with a bottom sealing block 9. A hollow buoyancy ball 10 is fixedly connected to the I-shaped frame 8. The bottom sealing block 9 cooperates with the through hole 7.

[0024] In the present invention, with the pre-buried vertical cylinder 1 as the main body of the device, first, the pre-buried vertical cylinder 1 is vertically installed underground and communicated with the sewage discharge pipe 4 and the rainwater discharge pipe 5, and at the same time, the sewage inlet pipe 3 is connected. On a normal sunny day, sewage enters the inside of the pre-buried vertical cylinder 1 through the sewage inlet pipe 3 and is discharged into the sewage treatment plant through the bottom sewage discharge pipe 4. When the rain is small, at this time, the rainwater passes through the through hole 7 and flows downward and still merges into the sewage and is discharged into the sewage treatment plant. If the rain is large, at this time, due to the blockage of the bottom sealing block 9 at the through hole 7, the downward flow of water is less than the water accumulation speed. At this time, water begins to accumulate on the top of the positioning disk 6. When the accumulated water exceeds the hollow buoyancy ball 10, at this time, under the action of buoyancy, the I-shaped frame 8 and the bottom sealing block 9 are driven to rise synchronously to block the through hole 7. At this time, all the rainwater is discharged through the rainwater discharge pipe 5 and will not merge into the sewage flow path at the bottom, reducing the pressure on the sewage treatment plant. And when the rainfall is not large, the rainwater continues to flow downward into the sewage, and the sewage discharge volume is large. At this time, the water level at the bottom of the positioning disk 6 begins to rise, and the bottom sealing block 9 will still rise due to buoyancy to block the through hole 7, preventing the sewage at the bottom from polluting the upper rainwater. Thus, the device has the advantages that when the rain is small, the sewage will not backflow and pollute, ensuring complete diversion, and solving the problem in the prior art that in the rain and sewage diversion device, when the rain is small, there is still sewage mixed in, and it is directly discharged into the river along with the rainwater, causing pollution and incomplete separation.

[0025] Please refer to Figure 1 , wherein: the right end of the rainwater discharge pipe 5 is fixedly connected with a pre-buried cylinder 51. An inner cylinder 52 is inserted into the pre-buried cylinder 51. A water inlet hole 53 communicating with the rainwater discharge pipe 5 is opened on the left side of the inner cylinder 52. A water outlet pipe 54 is fixedly connected to the right side of the pre-buried cylinder 51.

[0026] In the present utility model, rainwater is introduced into the interior of the inner net cylinder 52 through the water inlet holes 53 on the inner net cylinder 52 inside the embedded cylinder 51. The rainwater passes through the inner net cylinder 52 and is directly discharged into the river through the water outlet pipe 54. The inner net cylinder 52 filters and intercepts the sundries carried by the rainwater. After the rain, the inner net cylinder 52 can be directly hoisted vertically out of the embedded cylinder 51 to clean the sundries inside, which is convenient for operation and effectively prevents pipeline blockage.

[0027] Please refer to Figure 2 , wherein: a cover 521 is provided at the top of the inner net cylinder 52, and two hanging holes 522 are provided at the top end of the inner net cylinder 52.

[0028] In the present utility model, the inner net cylinder 52 can be conveniently opened through the cover 521, and the two hanging holes 522 are convenient for hoisting the inner net cylinder 52.

[0029] Please refer to Figure 1 and Figure 3 , wherein: a buoyancy block 91 is fixedly connected to the bottom of the bottom sealing block 9, and a conical top 92 is fixedly connected to the top of the bottom sealing block 9.

[0030] In the present utility model, when the water level at the bottom of the bottom sealing block 9 rises through the buoyancy block 91, it is smoothly lifted, and the conical top 92 reduces the flow resistance of the rainwater diversion at the top.

[0031] Please refer to Figure 1 , wherein: both the interior of the conical top 92 and the bottom sealing block 9 are hollow.

[0032] In the present utility model, through the hollow conical top 92 and bottom sealing block 9, the weight of the device is reduced, making it more sensitive to float.

[0033] Please refer to Figure 1 , wherein: limiting rings 81 are fixedly connected to the outer sides of the two vertical rods of the I-shaped frame 8.

[0034] In the present utility model, the vertical height of the I-shaped frame 8 is positioned through the limiting rings 81, so that the opening gap between the bottom sealing block 9 at the bottom and the through hole 7 remains in a fixed state, preventing excessive rainwater from flowing into the lower part and causing backflow.

[0035] The above is only the preferred specific embodiment of the present utility model; however, the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and its improvement concept of the present utility model, making equivalent replacements or changes, should be covered by the protection scope of the present utility model.
