Description

Technical Field

[0001] This utility model relates to the field of municipal engineering, and in particular to an automatic switching diverter for municipal rainwater and sewage separation pipelines. Background Technology

[0002] Municipal sewage pipes generally include branch pipes, trunk pipes, and main trunk pipes. Since rainwater does not require treatment and is typically discharged into nearby water bodies, rainwater pipes generally include branch pipes and trunk pipes. Rainwater and sewage separation is a drainage system that separates rainwater and sewage, each transported through its own pipe for discharge or subsequent treatment. Rainwater is discharged directly into rivers through a rainwater pipe network, while sewage is collected through a sewage pipe network and sent to a sewage treatment plant for treatment, preventing sewage from directly entering rivers and causing pollution.

[0003] For example, the invention patent with application number CN202210268317.8 discloses a rainwater and sewage diversion mechanism and diversion method for municipal pipelines, including a diversion well assembly. The diversion well assembly includes a well body and an inlet water pipe network, a rainwater pipe network and a sewage pipe network respectively connected to it. The top of the well body is provided with a well cover, and a lifting mechanism is installed on the top of the well cover. The telescopic end of the lifting mechanism is provided with a control valve assembly, which is slidably connected inside the well body. When the mechanism is at its highest point inside the well body, it controls the connection between the inlet water pipe network and the rainwater pipe network.

[0004] The aforementioned existing technology uses a mechanical method to separate rainwater and sewage through the control valve assembly. During use, it requires manual or remote control adjustment by staff according to weather conditions. The equipment is costly, and the control valve may fail due to malfunctions during long-term use, resulting in rainwater not being drained in time, causing road flooding and affecting pedestrian traffic.

[0005] Therefore, those skilled in the art have provided an automatic switching diverter for municipal stormwater and sewage separation pipelines to solve the problems mentioned in the background art. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an automatic switching diverter for municipal stormwater and sewage separation pipelines, which solves the problems mentioned in the background section.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0008] An automatic switching diverter for municipal stormwater and sewage separation pipelines includes a diversion well, which is a hollow rectangular body. A manhole cover is movably engaged at the top of the diversion well. An inlet pipe is connected to one side of the diversion well, and a stormwater pipe and a sewage pipe are connected to the other side of the diversion well, with the stormwater pipe located above the sewage pipe. An automatic switching diversion component is installed inside the diversion well cavity. The diversion component includes a rotating plate, a diversion part, and a rotating part. The diversion part includes an inlet fixedly installed at the top of the rotating plate. A converging pipe is connected to one side of the inlet, and a corrugated pipe is connected to one end of the converging pipe, which is inserted into the stormwater pipe cavity. The rotating part includes a semi-cylindrical block, a rotating shaft, and a counterweight block, with the counterweight block movably installed at the bottom of the rotating plate.

[0009] According to the aforementioned municipal stormwater and sewage separation pipeline automatic switching diverter, the semi-cylindrical block is fixedly installed at the bottom of the rotating plate, the rotating shaft is fixedly installed through the semi-cylindrical block, the rotating shaft is movably installed in the diversion well cavity, and the rotating plate is located between the inlet pipe and the stormwater pipe.

[0010] According to the aforementioned municipal stormwater and sewage separation pipeline automatic switching diverter, the inlet is located on the side near the inlet pipe, the corrugated pipe is located on the side near the stormwater pipe, the corrugated pipe is elastically expandable and contractible, the converging pipe is trapezoidal in shape, and the converging pipe is connected to the inlet and the corrugated pipe.

[0011] According to the aforementioned municipal stormwater and sewage separation pipeline automatic switching diverter, a baffle is fixedly installed on the bottom end of the rotating plate near the water inlet pipe, and there is an angle between the baffle and the rotating plate.

[0012] According to the aforementioned municipal stormwater and sewage separation pipeline automatic switching diverter, the bottom end of the rotating plate is fixedly installed on the side near the stormwater pipe, and the top of the counterweight is movably installed on the mounting base. There are multiple sets of counterweights.

[0013] According to the aforementioned municipal stormwater and sewage separation pipeline automatic switching diverter, the inlet is rectangular, the inlet cavity inlet area is larger than the inlet pipe, and a protective pad is fixedly installed on the inner wall of the end of the inlet near the inlet pipe. The protective pad is made of rubber.

[0014] This utility model provides an automatic switching diverter for municipal stormwater and sewage separation pipelines, which has the following beneficial effects:

[0015] (1) By setting a diversion component in the diversion well cavity, the rotating part and the guiding part work together to automatically adjust the guiding direction according to the flow rate. When the sewage flow rate is small, it flows directly through the diversion well and into the sewage treatment station through the sewage pipe. When it rains, the initial rainwater pollution is heavy and the flow rate is small, so it flows directly through the diversion well and into the sewage treatment station through the sewage pipe. When the rain is heavy, the rainwater flow rate in the inlet pipe is large, which causes the rotating part to drive the guiding part to rotate from the inclined state to the horizontal state. The rainwater enters the rainwater pipe through the diversion component and is directly discharged into the natural water body. The automatic guiding mechanism can quickly divert the rainstorm runoff and reduce the pressure on the pipe network. This device does not require an external power device, has a stable structure and low maintenance cost.

[0016] (2) By setting the inlet, the converging pipe and the corrugated pipe to be connected, when the rainwater flow is large, the rainwater is in the inlet and the converging pipe cavity. At this time, the weight of the rotating plate on the side closer to the inlet pipe is greater than that on the other side. After the inlet is close to the inner wall of the diversion well, the rotating plate is in a horizontal state. The rainwater is discharged directly into the rainwater pipe through the corrugated pipe. By setting the converging pipe to be in the shape of a trapezoid, the trapezoidal structure smoothly transitions the water flow, reduces local resistance, and avoids vibration noise and structural wear caused by turbulent impact.

[0017] (3) By fixing the mounting base at the bottom of the rotating plate and movably mounting the top of the counterweight on the mounting base, and by having multiple sets of counterweights, the rotating plate is tilted in the normal state, and the sewage directly enters the sewage pipe through the diversion well. By fixing the pad on the inner wall of the end of the inlet near the inlet pipe, the pad is made of rubber. When the rainwater flow increases, the rotating plate is in a horizontal state. At this time, the inlet is in contact with the inner wall of the diversion well. The pad can protect and buffer the inlet and extend its service life. Attached Figure Description

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Please see Figure 1-5 As shown, this utility model is an automatic switching diverter for municipal rainwater and sewage diversion pipelines, including a diversion well 10, which is a hollow rectangular body. A well cover 14 is movably engaged at the top of the diversion well 10. An inlet pipe 11 is connected through one side of the diversion well 10, and a rainwater pipe 12 and a sewage pipe 13 are connected through the other side of the diversion well 10. The rainwater pipe 12 is located above the sewage pipe 13. An automatic switching diversion component 15 is provided inside the cavity of the diversion well 10. The diversion component 15 includes a rotating plate 16, a diversion part, and a rotating part. The diversion part includes an inlet 17 fixedly installed at the top of the rotating plate 16. A converging pipe 18 is connected through one side of the inlet 17, and a corrugated pipe 19 is connected through one end of the converging pipe 18. The corrugated pipe 19 is inserted into the cavity of the rainwater pipe 12. The rotating part includes a semi-cylindrical block 20, a rotating shaft 21, and a counterweight 23. The counterweight 23 is movably installed at the bottom of the rotating plate 16.

[0027] Specifically, by installing a diversion component 15 inside the diversion well 10, the rotating part and the guiding part work together to automatically adjust the guiding direction according to the flow rate. When the sewage flow rate is small, it flows directly through the diversion well 10 and into the sewage treatment plant through the sewage pipe 13. When it rains, the initial rainwater pollution is relatively heavy and the flow rate is small, so it flows directly through the diversion well 10 and into the sewage treatment plant through the sewage pipe 13. When the rain is heavy, the rainwater flow rate in the inlet pipe 11 is large, causing the rotating part to drive the guiding part to rotate from an inclined state to a horizontal state. The rainwater enters the rainwater pipe 12 through the diversion component 15 and is directly discharged into the natural water body. The automatic guiding mechanism quickly diverts the rainstorm runoff and reduces the pressure on the pipe network. This device does not require an external power unit, has a stable structure, and has low maintenance costs.

[0028] Among them, such as Figure 1-3 As shown, the semi-cylindrical block 20 is fixedly installed at the bottom of the rotating plate 16, and the rotating shaft 21 is fixedly installed through the semi-cylindrical block 20. The rotating shaft 21 is movably installed in the cavity of the diversion well 10, and the rotating plate 16 is located between the water inlet pipe 11 and the rainwater pipe 12.

[0029] Specifically, by fixing the semi-cylindrical block 20 to the bottom of the rotating plate 16, and fixing the rotating shaft 21 through the semi-cylindrical block 20, the rotating shaft 21 is movably installed in the cavity of the diversion well 10, so that the two ends of the rotating plate 16 will rotate according to the change of gravity.

[0030] Among them, such as Figure 4 As shown, the inlet 17 is located on the side near the inlet pipe 11, and the corrugated pipe 19 is located on the side near the rainwater pipe 12. The corrugated pipe 19 can expand and contract elastically. The converging pipe 18 is truncated trapezoidal in shape and is connected to the inlet 17 and the corrugated pipe 19.

[0031] Specifically, by connecting the inlet 17, the converging pipe 18, and the corrugated pipe 19, when the rainwater flow is large, the rainwater is in the cavity of the inlet 17 and the converging pipe 18. At this time, the weight of the rotating plate 16 on the side closer to the inlet pipe 11 is greater than that on the other side. After the inlet 17 is close to the inner wall of the diversion well 10, the rotating plate 16 is in a horizontal state. The rainwater is directly discharged into the rainwater pipe 12 through the corrugated pipe 19. By setting the converging pipe 18 to be in the shape of a trapezoid, the trapezoidal structure smoothly transitions the water flow, reduces local resistance, and avoids vibration noise and structural wear caused by turbulent impact.

[0032] A baffle 22 is fixedly installed on the bottom end of the rotating plate 16 near the water inlet pipe 11, and there is an angle between the baffle 22 and the rotating plate 16.

[0033] Specifically, a baffle 22 is fixedly installed on the bottom end of the rotating plate 16 near the water inlet pipe 11. There is an angle between the baffle 22 and the rotating plate 16. The kinetic energy of the water flow impacting the baffle 22 is converted into a lateral component force, which enhances the active control capability of the water flow and reduces the driving load of the rotating shaft 21.

[0034] Among them, such as Figure 5 As shown, a mounting base 24 is fixedly installed on the bottom end of the rotating plate 16 near the rainwater pipe 12. The top of the counterweight 23 is movably installed on the mounting base 24. There are multiple sets of counterweights 23. The inlet 17 is rectangular. The inlet area of ​​the cavity of the inlet 17 is larger than that of the inlet pipe 11. A protective pad 25 is fixedly installed on the inner wall of the end of the inlet 17 near the inlet pipe 11. The protective pad 25 is made of rubber.

[0035] Specifically, by fixing the mounting base 24 at the bottom of the rotating plate 16, the top of the counterweight 23 is movably mounted on the mounting base 24. There are multiple sets of counterweights 23, so that the rotating plate 16 is tilted in the normal state, and the sewage directly enters the sewage pipe 13 through the diversion well 10. By fixing the protective pad 25 on the inner wall of the end of the inlet 17 near the inlet pipe 11, the protective pad 25 is made of rubber. When the rainwater flow increases, the rotating plate 16 is in a horizontal state. At this time, the inlet 17 is in contact with the inner wall of the diversion well 10. The protective pad 25 can protect and buffer the inlet 17 and extend its service life.

[0036] The working principle of this utility model of an automatic switching diverter for municipal stormwater and sewage diversion pipelines is as follows: By setting a diversion component 15 in the cavity of the diversion well 10, the rotating part and the guiding part work together to automatically adjust the guiding direction according to the flow rate. When the sewage flow rate is small, it flows directly through the diversion well 10 and into the sewage treatment plant through the sewage pipe 13. When it rains, the initial rainwater pollution is heavy and the flow rate is small, so it flows directly through the diversion well 10 and into the sewage treatment plant through the sewage pipe 13. When the rain is heavy, the rainwater flow rate in the inlet pipe 11 is large, which causes the rotating part to drive the guiding part to rotate from an inclined state to a horizontal state. The rainwater enters the rainwater pipe 12 through the diversion component 15 and is directly discharged into the natural water body. The automatic diversion mechanism can quickly divert the runoff of rainstorms and reduce the pressure on the pipe network. This device does not require an external power unit, has a stable structure, and has low maintenance costs.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
