Description

Technical Field

[0001] This utility model belongs to the field of municipal engineering, specifically, it relates to an anti-clogging device for rainwater and sewage separation wells. Background Technology

[0002] Separation wells for rainwater and sewage are key facilities in urban drainage systems. They are mainly used to separate rainwater and sewage for treatment, thereby improving sewage treatment efficiency, protecting the aquatic environment, and reducing the burden on the drainage system.

[0003] The prior art (publication number: CN220225650U) discloses a rainwater and sewage diversion well that is not clogged. The well includes a diversion well, with a combined pipe and a rainwater pipe connected to the left and right sides of the well, respectively. A sewage pipe is provided on the lower front side of the diversion well. An anti-clogging mechanism corresponding to the sewage pipe is provided on the lower inside of the diversion well. The anti-clogging mechanism includes a mudguard, a hydraulic cylinder and a water baffle. The mudguard is fixedly installed on the lower inside of the diversion well.

[0004] Existing technology prevents sewage pipes from being blocked by allowing silt to settle automatically by sealing the sewage outlet. However, while existing technology can prevent blockage, it cannot discharge sewage after sealing the sewage pipe. This means that when there is a lot of water in the diversion well, sewage will enter the rainwater pipe along with rainwater. Therefore, the anti-blockage structure of existing technology needs to be improved.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A rainwater and sewage separation well anti-clogging device includes:

[0008] The main body of the diversion well is a conventional rainwater and sewage diversion well. A sewage pipe is fixedly connected to the lower side of the diversion well body, and a rainwater pipe is fixedly connected to the upper side of the other side of the diversion well body. The sewage pipe and the rainwater pipe are cylindrical and can communicate with the cavity of the diversion well body.

[0009] The sedimentation structure is located at the bottom of the cavity of the diversion well body to prevent silt from clogging the sewage pipe. The sedimentation structure includes a high-pressure pipe and a filter screen. The high-pressure pipe is fixedly connected to the bottom of the cavity of the diversion well body, and the filter screen is fixedly connected to the wall of the high-pressure pipe. The high-pressure pipe can communicate with the sewage pipe.

[0010] In a preferred embodiment of this utility model, the high-pressure tube is a Z-shaped hollow tube with a closed upper opening and a lower opening that can connect to the end of the sewage pipe. The filter screen is located below the closed opening of the high-pressure tube and is an arc-shaped screen.

[0011] In a preferred embodiment of the present invention, the sedimentation structure further includes an inclined platform, a motor, a cover pipe, and a baffle plate. The inclined platform is fixedly connected to the bottom of the cavity of the diversion well body, the motor is fixedly connected to the inner wall of the cavity of the diversion well body, the cover pipe is fixedly connected to the bottom of the motor, the baffle plate is fixedly connected to the wall of the cover pipe, and a waterproof shell is installed on the wall of the motor.

[0012] In a preferred embodiment of this utility model, the inclined platform is in the shape of an inclined frustum, with the lowest point of the inclined surface facing the sewage pipe. A semi-circular opening is provided at the top of the connection between the high-pressure pipe and the sewage pipe. The cover pipe can block the opening on the wall of the high-pressure pipe. The cover plate is a rectangular plate and is symmetrically arranged on the front and rear walls of the cover pipe.

[0013] In a preferred embodiment of the present invention, the cavity of the diversion well body is further provided with a toggle structure, which includes a rotating shaft, a drive groove, a toggle plate and a moving rod. The rotating shaft is rotatably connected to the top of the cavity of the diversion well body, the drive groove is opened on the wall of the rotating shaft, the toggle plate is fixedly connected to the bottom of the rotating shaft, and the moving rod is fixedly connected to the top of the cover pipe.

[0014] In a preferred embodiment of the present invention, the rotating shaft is cylindrical, the driving groove is formed on the arc surface of the rotating shaft, the driving groove is threaded, the lever is rectangular, and multiple identical levers are arranged in a circular array at the bottom of the rotating shaft.

[0015] In a preferred embodiment of this utility model, the moving rod is an inverted L-shaped rod, and the side end of the moving rod can be engaged in the drive groove.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. By setting up a sedimentation structure and using a high-positioned filter screen to filter sewage, the sedimentation effect of silt in sewage is improved, while preventing the filter screen from being blocked. This achieves a dual filtration and anti-clogging effect. Furthermore, the sewage pipe will not be closed due to the need for sedimentation, which would cause silt to accidentally enter the rainwater pipe. Therefore, this solution has better performance than existing technologies.

[0018] 2. By setting up a toggle structure, the toggle plate can be automatically driven to stir the water in the main cavity of the diversion well when discharging sludge, thereby increasing the activity of the water in the main cavity of the diversion well and increasing the speed at which sludge is discharged from the sewage pipe.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0028] like Figure 1 and Figure 2 As shown, a rainwater and sewage separation well anti-clogging device includes: a separation well body 20, which is a conventional rainwater and sewage separation well. A sewage pipe 21 is fixedly connected to the lower side of the separation well body 20, and a rainwater pipe 22 is fixedly connected to the upper side of the other side of the separation well body 20. The sewage pipe 21 and the rainwater pipe 22 are cylindrical pipes, and the sewage pipe 21 and the rainwater pipe 22 can communicate with the cavity of the separation well body 20. This is existing technology, so it will not be described in detail here.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a sedimentation structure is installed at the bottom of the cavity of the diversion well body 20 to prevent silt from clogging the sewage pipe 21. The sedimentation structure includes a high-lift pipe 30 and a filter screen 31. The high-lift pipe 30 is fixedly connected to the bottom of the cavity of the diversion well body 20, and the filter screen 31 is fixedly connected to the wall of the high-lift pipe 30. The high-lift pipe 30 can communicate with the sewage pipe 21.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the high-pressure pipe 30 is a Z-shaped hollow tube. The upper opening of the high-pressure pipe 30 is closed, and the lower opening of the high-pressure pipe 30 can connect to the end of the sewage pipe 21. The filter screen 31 is located below the closed opening of the high-pressure pipe 30 and is an arc-shaped screen. The sedimentation structure also includes an inclined platform 32, a motor 33, a cover pipe 34, and a baffle plate 35. The inclined platform 32 is fixedly connected to the bottom of the cavity of the diversion well body 20. The motor 33 is fixedly connected to the inner wall of the cavity of the diversion well body 20. The cover pipe 34 is fixedly connected to the bottom of the motor 33. The baffle plate 35 is fixedly connected to the wall of the cover pipe 34. A waterproof shell is installed on the wall of the motor 33. The inclined platform 32 is a truncated cone shape. The lowest point of the inclined plane 32 faces the sewage pipe 21. A semi-circular opening is provided at the top of the connection between the high-pressure pipe 30 and the sewage pipe 21. The cover pipe 34 can block the opening on the wall of the high-pressure pipe 30. The cover plate 35 is a rectangular plate. The cover plate 35 is symmetrically arranged on the front and rear walls of the cover pipe 34. A toggle structure is also provided in the cavity of the diversion well body 20. The toggle structure includes a rotating shaft 37, a drive groove 38, a toggle plate 39 and a moving rod 36. The rotating shaft 37 is rotatably connected to the top of the cavity of the diversion well body 20. The drive groove 38 is opened on the wall of the rotating shaft 37. The toggle plate 39 is fixedly connected to the bottom of the rotating shaft 37. The moving rod 36 is fixedly connected to the top of the cover pipe 34.

[0031] In practical use, when sewage enters the diversion well body 20 during the initial stage of rainfall, it will accumulate in the diversion well body 20. As the sewage accumulates in the diversion well body 20, the silt in the sewage will settle. When the sewage in the diversion well body 20 reaches the filter screen 31, the sewage at the higher level will pass through the mesh of the filter screen 31 and enter the high-lift chamber 30. From the high-lift chamber 30, it will be guided into the sewage pipe 21, thus discharging the sewage from the sewage pipe 21. When it is necessary to discharge the silt accumulated in the diversion well body 20, the motor 33 is started. The motor 33 will retract upwards, and as the motor 33 retracts, it can drive the cover pipe 34 and the baffle plate 35 to move upwards synchronously. After the pipe 34 moves upward, the opening on the wall of the high pipe 30 will be open. The mud and sewage at the bottom of the diversion well body 20 will enter the sewage pipe 21 from the opening of the high pipe 30 and be discharged. After discharge, the control motor 33 will extend downward to drive the cover pipe 34 to close the opening on the wall of the high pipe 30. When the cover pipe 34 moves upward, the moving rod 36 will be driven by the cover pipe 34 to move upward synchronously. When the moving rod 36 moves upward, its wall will move along the drive groove 38. As the drive groove 38 contacts the moving rod 36, it can drive the rotating shaft 37 to rotate in the diversion well body 20. When the rotating shaft 37 rotates, it will drive the dial plate 39 to rotate. At this time, the dial plate 39 will stir the water in the diversion well body 20.

[0032] In summary, by setting up a sedimentation structure and using a high-positioned filter screen 31 to filter sewage, the sedimentation effect of silt in sewage is improved, while the filter screen 31 is prevented from being blocked, thus achieving a dual filtration and anti-clogging effect. Furthermore, the sewage pipe 21 will not be closed due to the need for sedimentation, preventing silt from accidentally entering the rainwater pipe 22. Therefore, this solution has better performance than existing technologies.

[0033] like Figure 1 , Figure 2 and Figure 5 As shown, the rotating shaft 37 is cylindrical, the drive groove 38 is opened on the arc surface of the rotating shaft 37, the drive groove 38 is a threaded groove, the lever plate 39 is a rectangular plate, and multiple identical lever plates 39 are arranged in a ring array at the bottom of the rotating shaft 37. The shift rod 36 is an inverted L-shaped rod, and the side end of the shift rod 36 can be engaged in the drive groove 38.

[0034] In actual use, the moving rod 36 will be driven by the cover pipe 34 to move upward synchronously. When the moving rod 36 moves upward, its wall will move along the drive groove 38. As the drive groove 38 comes into contact with the moving rod 36, it can drive the rotating shaft 37 to rotate in the cavity of the diversion well body 20. When the rotating shaft 37 rotates, it will drive the dial plate 39 to rotate. At this time, the dial plate 39 will stir the water in the cavity of the diversion well body 20.

[0035] In summary, by setting up a toggle structure, the toggle plate 39 can be automatically driven to stir the water in the cavity of the diversion well body 20 when discharging sludge, thereby increasing the activity of the water in the cavity of the diversion well body 20 and increasing the speed at which sludge is discharged from the sewage pipe 21.

[0036] Working principle: When sewage enters the diversion well body 20 during the initial stage of rainfall, it accumulates within the body. As the sewage accumulates, sediment settles. When the sediment reaches the filter screen 31, the higher sewage passes through the mesh of the filter screen 31 and enters the high-lift chamber 30. From there, it is directed into the sewage pipe 21, from which it is discharged. When it is necessary to remove the sediment accumulated in the diversion well body 20, the motor 33 is activated. The motor 33 retracts upwards, which in turn moves the cover pipe 34 and the baffle plate 35 upwards simultaneously. After 34 moves upward, the opening on the wall of the high-pressure pipe 30 will be open. The mud and sewage at the bottom of the diversion well body 20 will enter the sewage pipe 21 through the opening of the high-pressure pipe 30 and be discharged. After discharge, the control motor 33 will extend downward to drive the cover pipe 34 to close the opening on the wall of the high-pressure pipe 30. When the cover pipe 34 moves upward, the moving rod 36 will be driven by the cover pipe 34 to move upward synchronously. When the moving rod 36 moves upward, its wall will move along the drive groove 38. As the drive groove 38 contacts the moving rod 36, it can drive the rotating shaft 37 to rotate in the diversion well body 20. When the rotating shaft 37 rotates, it will drive the dial plate 39 to rotate. At this time, the dial plate 39 will stir the water in the diversion well body 20.

Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
