Description

Technical Field

[0001] The present invention relates to the technical field of sewage discharge, and particularly to a sewage diversion and discharge device that collects sewage on sunny days and discharges it on rainy days. Background Art

[0002] Under the background of the rapid development of the global economy and the acceleration of the urbanization process, the sewage discharge volume has been continuously increasing, posing a serious threat to the ecological environment. Sewage discharge has always been the focus of our attention. Therefore, the construction of drainage facilities has always been a top priority, especially for the construction of rural drainage facilities. Generally, there is a situation of combined sewage drainage in rural domestic sewage. On sunny days, the amount of sewage in the combined sewage channel is not large, almost all of which is domestic sewage, and all of it needs to be collected for treatment and reuse. However, on rainy days, the water volume in the drainage channel is large, and a large amount of sediment and bacteria are mixed with the rainwater. These water bodies generally need to be directly discharged, which will greatly increase the burden on the sewage treatment plant, and the treatment value of these sewage is not high. Therefore, a sewage diversion and discharge device needs to be set up to achieve sewage collection on sunny days and discharge on rainy days.

[0003] In the prior art, the sewage often contains relatively large impurities. When these impurities enter the device, it is very easy to cause blockage, resulting in the failure of the device. At the same time, most of the existing devices are manually operated. On rainy days, manual operation is required to change the drainage direction. On the one hand, the labor intensity is relatively large, and on the other hand, the situation of untimely diversion may occur. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems in the prior art, and a sewage diversion and discharge device that collects sewage on sunny days and discharges it on rainy days is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions: A sewage diversion and discharge device that collects sewage on sunny days and discharges it on rainy days, including a recovery pipe, a sewage discharge pipe, and a main body with an upwardly open concave cross-section. A fixed cylinder is fixedly connected to the inner bottom wall of the main body, and an intermediate column is fixedly connected to the inner side wall of the fixed cylinder through a support rod; A drainage mechanism is arranged in the main body, and the drainage mechanism is composed of a filtering component, a driving component, a discharging component, and a control component: The filtering component includes a filter screen, the filter screen is fixedly connected between the fixed cylinder and the intermediate column, and a rotating shaft is rotatably connected to the intermediate column through a bearing; The driving component includes a plurality of driving shafts, the driving shafts are rotatably connected to the fixed cylinder and the intermediate column through bearings, and a cavity is provided in the intermediate column; The discharging component includes a first pipe and a plurality of second pipes. The first pipe is fixedly connected to the bottom wall of the main body through penetration, the second pipes are fixedly connected to the fixed cylinder through penetration, and a first solenoid valve and a second solenoid valve are respectively arranged in the first pipe and the second pipes; The control component includes a plurality of sliding grooves which are formed on the side wall of the middle column; A stirring mechanism is arranged between the middle column and the fixed cylinder, and the stirring mechanism includes a lifting ring which is slidably connected to the inner side wall of the main body.

[0006] Furthermore, the filtering component further includes a plurality of scraping blocks which are fixedly connected to the side wall of the outer end of the rotating shaft located outside the middle column, and the cross section of the scraping block is a right triangle.

[0007] Furthermore, the driving component further includes a partition board which is fixedly connected between the middle column and the fixed cylinder. The partition board is provided with a plurality of through holes. A section of the driving shaft located between the middle column and the fixed cylinder penetrates and is fixedly connected with a water wheel, and the water wheel corresponds to the through holes one by one. The driving shaft penetrates and extends into the cavity and is fixedly connected with a driving bevel gear, and the rotating shaft penetrates and extends into the cavity and is fixedly connected with a driven bevel gear, and the driving bevel gear meshes with the driven bevel gear.

[0008] Furthermore, the discharging component further includes a third pipe which is fixedly connected to the side wall of the main body. The first pipe is fixedly connected to the recovery pipe through a flange, and the third pipe is fixedly connected to the sewage pipe through a flange.

[0009] Furthermore, the control component further includes a plurality of sliders which are slidably connected to the middle column through the sliding grooves. The sliders are fixedly connected with a buoyancy ring together. The upper surface of one of the sliders is fixedly connected with a button switch. A spring is fixedly connected between the slider and the top wall of the sliding groove. The button switch is electrically connected to the first solenoid valve and the second solenoid valve through a wire.

[0010] Furthermore, the stirring mechanism further includes a sliding sleeve which is fixedly connected to the inner side wall of the main body. The sliding sleeve is slidably connected with a sliding column. The sliding column is fixedly connected to the upper surface of the lifting ring. The upper surface of the sliding column is fixedly connected with a toothed frame. One of the driving shafts is rotatably connected to the sliding sleeve and the main body through a bearing and extends to the outside of the main body. A section of the driving shaft located inside the sliding sleeve is fixedly connected with a driving gear. The driving gear meshes with the toothed frame. The side wall of the main body is fixedly connected with a generator through a bracket. One end of the driving shaft located outside the main body is fixedly connected to the input shaft of the generator.

[0011] Furthermore, the surface of the scraping block is coated with a Teflon coating.

[0012] Furthermore, the buoyancy ring is made of polystyrene foam material and is coated with a polyurethane film on the outside.

[0013] Furthermore, the inner side wall of the main body is fixedly connected with a guiding ring, and the thickness of the guiding ring gradually decreases from the inner side wall of the main body towards the middle.

[0014] Further, the cross-sections of the sliding groove and the slider are both convex-shaped.

[0015] The present invention has the following advantages: 1. Through the setting of the filter screen, after the sewage enters the device, it is first filtered by the filter screen to prevent large impurities from entering the device, thus avoiding the situation of the device being blocked by impurities and ensuring the smooth discharge of sewage; 2. While the filter screen is filtering, the rotating shaft rotates, driving the scraping block to rotate, scraping the impurities on the filter screen. At the same time, as the scraping block rotates, with the cooperation of the inclined surface of the scraping block, the impurities in contact with the scraping block gradually leave the filter screen under the action of force and enter the gap between the fixed cylinder and the main body for storage, thus realizing the self-cleaning of the filter screen and avoiding the blockage of the filter screen by impurities, which affects the filtration; 3. After the water passes through the filter screen, it falls on the partition plate, then passes through the through holes and impacts the water wheel, driving the water wheel to rotate, and further driving the device to operate, so that the device does not require an external power mechanism, making the device more energy-saving; 4. On sunny days, the water volume is small, and all the water on the partition plate can pass through the through holes and fall. At this time, the button switch is not triggered, and the water enters the recovery pipe through the first pipe and then enters the sewage treatment plant. On rainy days, the water volume is large, and at this time, the water on the partition plate cannot be discharged in time, resulting in the accumulation of water on the partition plate, which in turn causes the switch to be triggered. At this time, the water directly passes through the second pipe, the third pipe and the sewage discharge pipe for discharge, thus realizing the automatic control of the water flow direction on sunny and rainy days, greatly reducing the labor intensity, and the diversion is more timely; 5. When discharging sewage on rainy days, the water volume is large and the water flow is fast. The impurities stored between the fixed cylinder and the main body are discharged together with the water flow through the faster water flow, thus realizing the self-cleaning of collecting impurities, without the need for regular manual cleaning, further reducing the labor intensity and improving the degree of automation; 6. While the rotating shaft rotates, it will also drive the driving gear to rotate. Through the meshing of the driving gear and the tooth frame, the slider drives the lifting ring to move up and down reciprocally, so that the dialing block moves up and down reciprocally, continuously stirring the impurities, making them flow away smoothly with the water flow and preventing them from adhering to the main body and the fixed cylinder.

Specific embodiments

[0018] 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. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Embodiment Refer to Figure 1-8 , a sewage diversion and discharge device with rain collection and sewage discharge in sunny days, including a recovery pipe 33, a sewage discharge pipe 34, and a main body 1 with a concave shape with an upward opening cross-section. The inner bottom wall of the main body 1 is fixedly connected with a fixed cylinder 2, and the inner side wall of the fixed cylinder 2 is fixedly connected with an intermediate column 3 through a support rod 4; A drainage mechanism is arranged in the main body 1, and the drainage mechanism is composed of a filtering component, a driving component, a discharging component, and a control component: The filtering component includes a filter screen 5. The filter screen 5 is fixedly connected between the fixed cylinder 2 and the intermediate column 3, and the intermediate column 3 is rotatably connected through a bearing with a rotating shaft 9; The driving component includes a plurality of driving shafts 12. The driving shafts 12 are rotatably connected through bearings with the fixed cylinder 2 and the intermediate column 3, and the intermediate column 3 is provided with a cavity 8; The discharge component includes a first pipe 15 and a plurality of second pipes 17. The first pipe 15 is fixedly connected through the bottom wall of the main body 1, and the second pipes 17 are fixedly connected through the fixed cylinder 2. A first solenoid valve 16 and a second solenoid valve 18 are respectively arranged in the first pipe 15 and the second pipes 17. The first solenoid valve 16 is a normally open solenoid valve, which closes when powered on, and the second solenoid valve 18 is a normally closed solenoid valve, which opens when powered on; The control component includes a plurality of sliding grooves 20, which are opened on the side wall of the middle column 3; A stirring mechanism is arranged between the middle column 3 and the fixed cylinder 2. The stirring mechanism includes a lifting ring 25 slidably connected to the inner side wall of the main body 1. The lifting ring 25 is an incomplete circular ring (as Figure 5 shown).

[0020] The filtering component further includes a plurality of scraping blocks 10. The scraping blocks 10 are fixedly connected to the side wall of the outer end of the rotating shaft 9 located outside the middle column 3. The cross section of the scraping block 10 is a right triangle (as Figure 5 shown), that is, one side of the scraping block 10 is an inclined surface. During its rotation, the inclined surface contacts the impurities on the filter screen 5 and pushes them to move. At this time, the component force of the force received by the impurities will cause the impurities to slide along the inclined surface until they leave the upper surface of the filter screen 5. Through the setting of the filter screen 5, large impurities are blocked to prevent them from entering the fixed cylinder 2 and affecting the operation of the device. During the diversion process, the rotating shaft 9 drives the scraping block 10 to rotate, and the rotation of the scraping block 10 will push the impurities on the filter screen 5, making them gradually move away from the filter screen 5 and fall from the filter screen 5 into the storage between the main body 1 and the fixed cylinder 2, thus realizing the self-cleaning of the filter screen 5 and preventing impurities from blocking the filter screen 5 and affecting normal sewage discharge.

[0021] The driving component further includes a partition plate 6, which is fixedly connected between the middle column 3 and the fixed cylinder 2. The partition plate 6 is provided with a plurality of through holes 7. A section of the driving shaft 12 located between the middle column 3 and the fixed cylinder 2 is fixedly connected with a water wheel 14 through. The water wheel 14 has a plurality of blades. The water flowing down through the through holes 7 impacts the blades of the water wheel 14, which can cause the water wheel 14 to rotate. The water wheel 14 corresponds to the through holes 7 one by one. The driving shaft 12 penetrates and extends into the cavity 8 and is fixedly connected with a driving bevel gear 13. The rotating shaft 9 penetrates and extends into the cavity 8 and is fixedly connected with a driven bevel gear 11. The driving bevel gear 13 meshes with the driven bevel gear 11. After the sewage enters the fixed cylinder 2, it falls on the partition plate 6 and then falls through the through holes 7 of the partition plate 6. After the sewage falls, it impacts the blades of the water wheel 14, causing the water wheel 14 to rotate. The water wheel 14 drives the driving shaft 12 to rotate. The driving shaft 12 drives the driving bevel gear 13 to rotate. The rotation of the driving bevel gear 13 drives the driven bevel gear 11 meshing with it to rotate. The driven bevel gear 11 drives the rotating shaft 9 to rotate. The device is driven by the gravity of the falling sewage without external power components, making the device more energy-saving.

[0022] It is worth mentioning that the rotation speed of the scraping block 10 is related to the rotation speed of the drive shaft 12, and the rotation speed of the drive shaft 12 is related to the water flow rate. That is, the greater the water flow rate, the faster the rotation speed of the scraping block 10, and vice versa. Thus, the device can automatically adjust the cleaning rate of the filter screen 5 according to the water flow rate.

[0023] The discharge component further includes a third pipe 19. The third pipe 19 is fixedly connected to the side wall of the main body 1. The first pipe 15 is fixedly connected to the recovery pipe 33 through a flange. The recovery pipe 33 is connected to the pipe for transporting sewage to the sewage treatment plant. The third pipe 19 is fixedly connected to the sewage discharge pipe 34 through a flange. The sewage discharge pipe 34 is connected to the pipe for discharging sewage into the river.

[0024] The control component further includes a plurality of sliders 21. The sliders 21 are slidably connected to the middle column 3 through sliding grooves 20. The sliders 21 are fixedly connected to a buoyancy ring 22 together. A button switch 23 is fixedly connected to the upper surface of one of the sliders 21. The button switch 23 is a special underwater switch with an IP68 waterproof performance, thus ensuring its normal use in water. A spring 24 is fixedly connected between the slider 21 and the inner top wall of the sliding groove 20. The button switch 23 is electrically connected to the first solenoid valve 16 and the second solenoid valve 18 through wires. After the button switch 23 is pressed, the first solenoid valve 16 and the second solenoid valve 18 can be powered on. When it is sunny, the sewage is mostly domestic wastewater at this time, and the water flow rate is small. After the water falls from the filter screen 5, the multiple through holes 7 can quickly drain the water, so that the sewage enters the recovery pipe 33 through the first pipe 15 and is then discharged into the sewage treatment plant for treatment through the recovery pipe 33. When it is rainy, the sewage is a mixture of domestic sewage and rainwater at this time, and the water flow rate is large. At this time, more water enters the device. After the water falls on the partition plate 6, the multiple through holes 7 cannot drain the water in time, resulting in the accumulation of water on the partition plate 6. As the amount of water on the partition plate 6 continuously increases, until the sewage contacts the buoyancy ring 22, the buoyancy ring 22 rises due to buoyancy, and the buoyancy ring 22 drives the slider 21 to rise. When the slider 21 contacts the button switch 23, the button switch 23 is triggered. At this time, the first solenoid valve 16 is powered on and closed, and the second solenoid valve 18 is powered on and opened. At this time, the falling sewage will be discharged through the second pipe 17 and pass through the gap between the main body 1 and the fixed cylinder 2, and finally be discharged into the sewage discharge pipe 34 through the third pipe 19 for direct discharge. Thus, the device can automatically control the sewage diversion direction according to the water flow rate, without manual operation, greatly reducing the workload and making the diversion more timely.

[0025] The stirring mechanism further includes a sliding sleeve 27, which is fixedly connected to the inner side wall of the main body 1. A sliding column 28 is slidably connected to the sliding sleeve 27. The sliding column 28 is fixedly connected to the upper surface of the lifting ring 25. A toothed frame 29 is fixedly connected to the upper surface of the sliding column 28. One of the drive shafts 12 is rotatably connected to the sliding sleeve 27 and the main body 1 through bearings and extends to the outside of the main body 1. A drive gear 30 is fixedly connected to a section of the drive shaft 12 located inside the sliding sleeve 27. The drive gear 30 meshes with the toothed frame 29. Teeth are provided on two opposite inner side walls of the toothed frame 29 (as shown in Figure 8 ), and the drive gear 30 is an incomplete gear (as shown in Figure 8 ). When the drive gear 30 rotates, it can alternately mesh with the teeth on the two inner side walls of the toothed frame 29, so that the toothed frame 29 moves up and down reciprocally. The side wall of the main body 1 is fixedly connected to a generator 31 through a bracket. One end of the drive shaft 12 located outside the main body 1 is fixedly connected to the input shaft of the generator 31. When the drive shaft 12 rotates, it drives the generator 31 to rotate, generating electric energy for the use of the push button switch 23 and the first solenoid valve 16 and the second solenoid valve 18. When the drive shaft 12 rotates, it also drives the drive gear 30 to rotate. When the drive gear 30 rotates, it will alternately mesh with the teeth on the two opposite inner side walls of the toothed frame 29. Thus, when the drive gear 30 rotates, it drives the toothed frame 29 to move up and down reciprocally. The toothed frame 29 drives the sliding column 28 to move up and down reciprocally. The sliding column 28 drives the lifting ring 25 to move up and down reciprocally. Finally, the slider 26 moves up and down reciprocally with the lifting ring 25. Through the up and down reciprocating movement of the lifting ring 25 and the slider 26, the impurities between the stirring main body 1 and the fixed cylinder 2 are agitated, so that they can better enter the third pipe 19 with the water flow, avoiding the impurities adhering to the main body 1 and the fixed cylinder 2 and ensuring the complete discharge of the impurities.

[0026] The surface of the scraping block 10 is coated with a Teflon coating. The Teflon coating has properties such as low friction, corrosion resistance, anti-sticking and high insulation. On the one hand, it avoids the corrosion of the scraping block 10. On the other hand, it can reduce the friction between the impurities and the scraping block 10, so that the impurities can be better sent away from above the filter screen 5 by the scraping block 10.

[0027] The buoyancy ring 22 is made of polystyrene foam. The polystyrene foam has a porous structure and a small density, and has a large buoyancy in water, which can better trigger the push button switch 23. And its outside is coated with a polyurethane film. The externally wrapped polyurethane film has waterproof and anti-corrosion functions, avoiding the corrosion of the buoyancy ring 22 caused by long-term contact with sewage and affecting its function.

[0028] A guiding ring 32 is fixedly connected to the inner side wall of the main body 1. The thickness of the guiding ring 32 gradually decreases from the inner side wall of the main body 1 to the middle (as shown in Figure 2 ). Through the setting of the guiding ring 32, the water flow entering the device can flow above the filter screen 5, so as to be filtered and then discharged.

[0029] The cross-sections of both the sliding groove 20 and the slider 21 are convex-shaped (as Figure 6 shown), and the sliding connection between the convex-shaped slider 21 and the sliding groove 20 is more stable, preventing the slider 21 from detaching from the sliding groove 20.

[0030] In the present invention, sewage flows into the device through the drainage channel. Under the guiding action of the guiding ring 32, the sewage falls onto the filter screen 5 along the guiding ring 32. Larger impurities will remain on the filter screen 5, and the sewage will enter the fixed cylinder 2 through the filter screen 5.

[0031] After the sewage enters the fixed cylinder 2, it falls onto the partition plate 6, and then falls through the through holes 7 of the partition plate 6. After the sewage falls, it impacts the blades of the water wheel 14, causing the water wheel 14 to rotate. The water wheel 14 drives the drive shaft 12 to rotate, the drive shaft 12 drives the driving bevel gear 13 to rotate, the rotation of the driving bevel gear 13 drives the driven bevel gear 11 meshing with it to rotate, the driven bevel gear 11 drives the rotating shaft 9 to rotate, the rotating shaft 9 drives the scraping block 10 to rotate, and the rotation of the scraping block 10 will push the impurities on the filter screen 5, causing them to gradually move away from the filter screen 5 and fall from the filter screen 5, falling into the storage space between the main body 1 and the fixed cylinder 2.

[0032] When it is sunny, at this time the sewage is mostly domestic wastewater with a small water flow. After the water falls from the filter screen 5, the multiple through holes 7 can quickly drain the water, so that the sewage enters the recovery pipe 33 through the first pipe 15 and is then discharged into the sewage treatment plant for treatment through the recovery pipe 33.

[0033] When it is rainy, at this time the sewage is a mixture of domestic sewage and rainwater with a large water flow. At this time, more water enters the device. After the water falls onto the partition plate 6, the multiple through holes 7 cannot drain the water in time, resulting in the accumulation of water on the partition plate 6. As the amount of water on the partition plate 6 continues to increase until the sewage contacts the buoyancy ring 22, the buoyancy causes the buoyancy ring 22 to rise. The buoyancy ring 22 drives the slider 21 to rise. When the slider 21 contacts the button switch 23, the button switch 23 is triggered. At this time, the first solenoid valve 16 is energized and closed, and the second solenoid valve 18 is energized and opened. At this time, the falling sewage will be discharged through the second pipe 17 and pass through the gap between the main body 1 and the fixed cylinder 2, and finally be directly discharged into the sewage discharge pipe 34 through the third pipe 19.

[0034] Since the sewage is discharged through the second pipe 17 and enters the third pipe 19, it will pass through the entire gap between the main body 1 and the fixed cylinder 2. And during rainy days, the water flow is large and the flow rate is fast, and the sewage will also wash away and discharge the impurities between the main body 1 and the fixed cylinder 2 at the same time.

[0035] When one of the drive shafts 12 rotates, it will also drive the generator 31 to rotate to generate electrical energy for the device to use. At the same time, when the drive shaft 12 rotates, it will also drive the drive gear 30 to rotate. When the drive gear 30 rotates, it will alternately engage with the teeth on the two inner side walls of the tooth frame 29, so that when the drive gear 30 rotates, it drives the tooth frame 29 to move up and down reciprocally. The tooth frame 29 drives the sliding column 28 to move up and down reciprocally, and the sliding column 28 drives the lifting ring 25 to move up and down reciprocally. Finally, the shifting block 26 moves up and down reciprocally with the lifting ring 25. Through the up and down reciprocating movement of the lifting ring 25 and the shifting block 26, the impurities between the main body 1 and the fixed cylinder 2 are agitated, so that they can better enter the third pipe 19 with the water flow, and avoid the impurities from adhering to the main body 1 and the fixed cylinder 2.

[0036] After the rain stops, the water flow entering the device at this time decreases, and the water on the partition plate 6 will also slowly drain out. As the accumulated water on the partition plate 6 drains out, the water surface continuously drops. Under the elastic force of the spring 24, the slider 21 and the buoyancy ring 22 are reset. At this time, the push button switch 23 is released, the first solenoid valve 16 is powered off and opened, and the second solenoid valve 18 is powered off and closed. At this time, the sewage will enter the recovery pipe 33 through the first pipe 15 again.

[0037] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
