Description

Technical Field

[0001] This utility model relates to the field of environmental engineering technology, and in particular to a rainwater and sewage separation structure for a mixed-flow sewage pipe. Background Technology

[0002] Mixed-flow sewage pipes with separate stormwater and wastewater systems are used to separate and collect rainwater and wastewater: rainwater can be directly discharged into natural water bodies, while wastewater enters a treatment system to meet standards before being discharged. This effectively reduces direct sewage discharge into rivers and lakes, improving water quality. It aligns with the requirements of ecological civilization construction and contributes to achieving sustainable development goals.

[0003] Combined sewer systems utilize the differences in water quality, flow rate variations, and gravity flow characteristics between rainwater and sewage to achieve separation. In the initial stages of rainfall, surface runoff carrying impurities enters the sewage system as initial rainwater. As rainfall increases, clean rainwater overflows into natural water bodies, while sewage continuously enters the treatment system. This addresses pollution problems in aging combined sewer systems, such as those in urban villages and old industrial areas.

[0004] In some mixed-flow sewage pipe rainwater and sewage separation structures, garbage and debris in the sewage remain on the inner wall of the rainwater and sewage separator during the separation process. This leads to excessive accumulation of garbage or impurities inside the separator, causing blockage. To address this issue, a rainwater and sewage separation structure for mixed-flow sewage pipes is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a rainwater and sewage separation structure for mixed-flow sewage pipes, aiming to improve the problem in some existing mixed-flow sewage pipe rainwater and sewage separation structures where garbage and debris in the sewage remain on the inner wall of the rainwater and sewage separator during the separation of rainwater and sewage, resulting in excessive accumulation of garbage or impurities inside the separator and clogging of the separator.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A rainwater and sewage separation structure for a mixed-flow sewage pipe includes a rainwater and sewage separation pipe. A support plate is fixedly connected to the bottom of the inner wall of the rainwater and sewage separation pipe. A motor is fixedly connected to the outer wall of the support plate. A rotating bracket is fixedly connected to the drive end of the motor. A crossbar is fixedly connected to the outer wall of the rotating bracket. Multiple forks are fixedly connected to the bottom of the crossbar. A sewage outlet is provided at the bottom of the rainwater and sewage separation pipe. A filter plate is detachably connected to the top of the rainwater and sewage separation pipe. A cleaning component for cleaning is installed on the inner wall of the filter plate.

[0008] As a further description of the above technical solution:

[0009] The cleaning assembly includes a cleaning tube, the outer wall of which is fixedly connected to a plurality of fixing rings, the outer wall of which is fixedly connected to a conical plate, and the outer wall of which is fixedly connected to a high-pressure water pump.

[0010] As a further description of the above technical solution:

[0011] The inner wall of the conical plate is rotatably connected to a sliding ball, and the top of the sliding ball is fixedly connected to a conical nozzle.

[0012] As a further description of the above technical solution:

[0013] The outer wall of the sliding ball is provided with multiple water outlet grooves, and the outer wall of the filter plate is provided with multiple water outlet grooves;

[0014] As a further description of the above technical solution:

[0015] A fixing plate is fixedly connected to the outer wall of the rainwater and sewage separation pipe, and a rain sensor is fixedly connected to the top of the fixing plate.

[0016] As a further description of the above technical solution:

[0017] The inner wall of the rainwater and sewage separation pipe is fixedly connected to a second sewage pipe, and the outer wall of the second sewage pipe is fixedly connected to a lift pump.

[0018] As a further description of the above technical solution:

[0019] A water quality monitor is fixedly connected to the inner wall of the rainwater and sewage separation pipe, a liquid level sensor is fixedly connected to the inner wall of the rainwater and sewage separation pipe, and a sewage pipe is fixedly connected to the outer wall of the rainwater and sewage separation pipe.

[0020] As a further description of the above technical solution:

[0021] The outer wall of the rainwater and sewage separation pipe is fixedly connected to a rainwater drain pipe, and the inner wall of the rainwater and sewage separation pipe is equipped with a sluice gate.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the motor starts, and the starting of the motor drives the rotating bracket to rotate. The rotation of the rotating bracket drives multiple crossbars to move in a circle, thereby causing the forks to scrape the inner wall, thus preventing excessive accumulation inside the rainwater and sewage separator from clogging the inside of the separator, causing rainwater and sewage to be unable to be separated according to the design path, or even causing rainwater and sewage to mix.

[0024] 2. In this utility model, water is pumped into the inner wall of the cleaning pipe by a high-pressure water pump. The high-pressure water pump generates high pressure. At this time, the water flow is transmitted through the fixed ring to the inner wall of the water outlet groove opened on the outer wall of the sliding ball and the conical nozzle. At this time, the water flow flows along the shape of the water outlet groove inside the water outlet groove. At the same time, the water flow drives the sliding ball and the conical nozzle to rotate on the inner wall of the conical plate, thereby realizing the rotation and facilitating the uniform spraying of water on the inner wall for cleaning.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1 to 3This utility model provides an embodiment of a rainwater and sewage separation structure for a mixed-flow sewage pipe, including a rainwater and sewage separation pipe 1. A support plate 3 is fixedly connected to the bottom of the inner wall of the rainwater and sewage separation pipe 1. The support plate 3 provides an installation base for a motor 2. The motor 2 is fixedly connected to the outer wall of the support plate 3. The motor 2 serves as a power source and can drive a rotating bracket 5 to rotate. The rotating bracket 5 is fixedly connected to the drive end of the motor 2. The rotating bracket 5 rotates with the drive end of the motor 2. A crossbar 6 is fixedly connected to the outer wall of the rotating bracket 5. The crossbar 6 makes a circular motion with the rotation of the rotating bracket 5. Multiple forks 4 are fixedly connected to the bottom of the crossbar 6. The forks 4 scrape the inner wall of the rainwater and sewage separation pipe 1 to clean impurities and garbage as the crossbar 6 moves in a circular motion.

[0032] The bottom of the rainwater and sewage diversion pipe 1 is provided with a sewage outlet 7, which is used for the entry of impurities and garbage scraped by the forklift 4. The top of the rainwater and sewage diversion pipe 1 is detachably connected to a filter plate 23, which can filter larger impurities in the sewage. The inner wall of the filter plate 23 is equipped with a cleaning component for cleaning, which can clean the inner wall of the rainwater and sewage diversion pipe 1. The outer wall of the rainwater and sewage diversion pipe 1 is fixedly connected to a fixing plate 20, which provides a mounting carrier for the rain sensor 21. The top of the fixing plate 20 is fixedly connected to the rain sensor 21, which can monitor the rainfall to facilitate the system control of rainwater and sewage diversion.

[0033] The inner wall of the rainwater and sewage diversion pipe 1 is fixedly connected to a second sewage pipe 24, which is used to discharge sewage that has accumulated to a certain extent. The outer wall of the second sewage pipe 24 is fixedly connected to a lift pump 16, which provides power for the sewage to be discharged through the second sewage pipe 24. The inner wall of the rainwater and sewage diversion pipe 1 is fixedly connected to a water quality monitor 18, which can monitor the water quality in the pipe in real time. The inner wall of the rainwater and sewage diversion pipe 1 is fixedly connected to a liquid level sensor 17, which can monitor the liquid level in the pipe in real time. The outer wall of the rainwater and sewage diversion pipe 1 is fixedly connected to a first sewage pipe 19, which is used to discharge the sewage that has initially leaked in.

[0034] Reference Figures 1 to 3 The cleaning assembly includes a cleaning pipe 9, which is a channel for water flow transmission. Multiple fixing rings 10 are fixedly connected to the outer wall of the cleaning pipe 9. The fixing rings 10 are used to fix the conical plate 11 and assist in water flow transmission. The conical plate 11 is fixedly connected to the outer wall of the fixing rings 10. The conical plate 11 provides rotation space for the sliding ball 12 and the conical nozzle 13. A high-pressure water pump 8 is fixedly connected to the outer wall of the cleaning pipe 9. The high-pressure water pump 8 can generate high-pressure water flow to achieve the cleaning function. The sliding ball 12 is rotatably connected to the inner wall of the conical plate 11. The sliding ball 12 can rotate under the impact of water flow on the inner wall of the conical plate 11.

[0035] A conical nozzle 13 is fixedly connected to the top of the sliding ball 12. The conical nozzle 13 rotates with the sliding ball 12 to spray water evenly. Multiple water outlet grooves 22 are opened on the outer wall of the sliding ball 12. The water outlet grooves 22 are the path of water flow and their shape affects the direction of water flow. Multiple water outlet grooves 22 are opened on the outer wall of the filter plate 23. The water outlet grooves 22 allow the cleaned water to flow through the filter plate 23 and be discharged. A rainwater drain pipe 14 is fixedly connected to the outer wall of the rainwater and sewage diversion pipe 1. The rainwater drain pipe 14 is used to discharge rainwater that meets the conditions. A water gate 15 is installed on the inner wall of the rainwater and sewage diversion pipe 1. The water gate 15 can be controlled to open and release water according to the water quality and liquid level monitoring results to achieve rainwater and sewage diversion.

[0036] Working principle: When it is necessary to clean the debris and garbage brought by the sewage on the inner wall, the motor 2 starts. The start of the motor 2 drives the rotating bracket 5 to rotate. The rotation of the rotating bracket 5 drives multiple crossbars 6 to move in a circle, so that the fork 4 scrapes the inner wall. This scrapes the impurities and garbage into the drain outlet 7, thereby preventing excessive accumulation inside the rainwater and sewage separator and clogging the inside of the separator, which would prevent rainwater and sewage from being separated according to the design path, or even cause rainwater and sewage to mix.

[0037] When the inner wall needs to be cleaned, water is pumped into the inner wall of the cleaning pipe 9 by the high-pressure water pump 8. The high-pressure water pump 8 generates high pressure, and the water flow is transmitted through the fixed ring 10 to the inner wall of the water outlet groove 22 opened on the outer wall of the sliding ball 12 and the conical nozzle 13. At this time, the water flow flows along the shape of the water outlet groove 22 inside the water outlet groove 22. At the same time, the water flow drives the sliding ball 12 and the conical nozzle 13 to rotate on the inner wall of the conical plate 11, thereby achieving rotation and facilitating the even spraying of water on the inner wall for cleaning.

[0038] When rainwater and sewage need to be separated, sewage leaks into the inner wall through the filter plate 23 and is discharged through the sewage pipe 19. When the sewage accumulates to a certain level, the booster pump 16 discharges the sewage through the sewage pipe 24. Then, the water quality monitor 18 detects the water quality and the liquid level sensor 17 detects the liquid level. When the water quality and liquid level on the inner wall reach a certain level, the sluice gate 15 opens to release water, which facilitates the discharge of rainwater, thereby realizing the separation of rainwater and sewage.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
