Description

Technical Field

[0001] The invention belongs to the technical field of rainwater and sewage diversion, and in particular is a rainwater and sewage diversion device for urban buildings. Background Art

[0002] With the development of economy and the enhancement of environmental protection awareness, water resources are becoming more and more precious. In order to make better use of rainwater resources, my country has implemented a drainage method in which rainwater and sewage are discharged through separate municipal drainage pipes, that is, rainwater and sewage diversion. Rainwater and sewage diversion refers to the separation of rainwater and sewage, each using a pipe for transportation, and discharge or subsequent treatment. Rainwater is discharged directly into the river through the rainwater pipe network, and sewage is concentrated through the sewage pipe network and sent to the sewage treatment plant for treatment, thus avoiding sewage directly entering the river and causing pollution. In addition, the collection, utilization and centralized management of rainwater discharge can reduce the impact of water on sewage treatment plants and ensure the treatment efficiency of sewage treatment plants.

[0003] Rainwater is less polluted and can be discharged directly into rivers after diversion. After natural sedimentation, it can be used as natural landscape water or as urban municipal water for spraying roads. Therefore, rainwater flows into rivers after purification and buffering, which can improve the efficiency of surface water use. At the same time, sewage is concentrated and discharged into the sewage network, and treated by sewage treatment plants to achieve sewage regeneration. After the diversion of rainwater and sewage, the sewage collection rate can be accelerated, the sewage treatment rate can be improved, and sewage pollution to rivers and groundwater can be avoided. It can not only improve the urban water environment, but also reduce the cost of sewage treatment.

[0004] In the prior art, the drainage of rainwater and sewage is generally completely independent. However, in daily life, residents often dump untreated domestic sewage into manhole covers, automobile exhaust pollution, oil stains left on the ground by open-air vendors, etc. The rainwater in the early stage of rainfall will dissolve a large amount of the above pollutants by washing roofs and roads. Discharging them into a separate rainwater pipe will aggravate the pollution of natural water bodies. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the embodiments of the present invention is to provide a rainwater and sewage diversion device for urban buildings.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a rainwater and sewage diversion device for urban buildings, comprising a diversion well frame and a partition, the diversion well frame is divided into a rainwater area and a sewage area by the partition, and also comprises a curved pipe, a wheel body, and a water storage frame, the two side walls of the sewage area are respectively provided with a sewage inlet pipe and a sewage outlet pipe, the two side walls of the rainwater area are respectively provided with a rainwater inlet pipe and a rainwater outlet pipe, a second torsion spring is fixedly installed on the rainwater inlet pipe, one end of the second torsion spring is fixedly installed with a curved pipe, and a water absorbing pipe is fixedly installed on one end of the rainwater inlet pipe located in the rainwater area A rubber ring is provided in the sewage area, a wheel body is fixedly installed on one side of the wheel body with a rotating shaft, the rotating shaft is rotatably connected to the diversion well frame, a first torsion spring is fixedly installed on the rotating shaft and the side wall of the diversion well frame, a plurality of water storage frames are circumferentially arranged on the wheel body, one end of the water storage frame is open, the open end of the water storage frame corresponds to the bent pipe, a first push rod, a second push rod and a third push rod are respectively fixedly installed on the water storage frame, the water storage frame below the first push rod is positioned opposite to the bent pipe outlet, and the widths of the first push rod, the second push rod and the third push rod gradually increase.

[0008] As a further improvement scheme: a clearance groove is provided on the partition at a position corresponding to the bent pipe.

[0009] As a further improvement scheme: a baffle is slidably connected to one side of the partition located in the rainwater area, the baffle is located directly below the give way groove, and a floating plate is fixedly installed on one end of the baffle away from the give way groove.

[0022] The technical solution of the present application is further described in detail below in conjunction with specific implementation methods.

[0023] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0024] See also Figures 1 to 6 In one embodiment, a rainwater and sewage diversion device for urban buildings includes a diversion well frame 1 and a partition 13. A cover plate 8 is also installed on the top of the diversion well frame 1. The diversion well frame 1 is divided into a rainwater area and a sewage area by the partition 13. It also includes a curved pipe 9, a wheel body 12, and a water storage frame 22. The two side walls of the sewage area are respectively provided with a sewage inlet pipe 3 and a sewage outlet pipe 10. The two side walls of the rainwater area are respectively provided with a rainwater inlet pipe 4 and a rainwater outlet pipe 11. The sewage inlet pipe 3 and the rainwater inlet pipe 4 are provided with At a higher position of the diversion well frame 1, the sewage outlet pipe 10 and the rainwater outlet pipe 11 are arranged at a lower position of the diversion well frame 1, and the sewage outlet pipe 10 and the rainwater outlet pipe 11 are at a certain distance from the bottom of the diversion well frame 1. A support ring 41 is fixedly installed on the rainwater inlet pipe 4, and an annular groove 42 is provided on the rainwater inlet pipe 4. A second torsion spring 27 is fixedly installed on the support ring 41, and a fixing ring 91 is fixedly installed at one end of the second torsion spring 27. The fixing ring 91 is fixedly installed with the inner part of the bent pipe 9. The rainwater inlet pipe 4 is fixedly connected to the wall, and a water-absorbing rubber ring 26 is fixedly installed on one end of the rainwater inlet pipe 4 located in the rainwater area. The water-absorbing rubber ring 26 is arranged in an inclined direction and inclined toward the inner wall of the curved pipe 9. The water-absorbing rubber ring 26 has the characteristics of swelling when absorbing water and shrinking when losing water. A wheel body 12 is arranged in the sewage area, and a rotating shaft 6 is fixedly installed on one side of the wheel body 12. The rotating shaft 6 is rotatably connected to the diversion well frame 1. The rotating shaft 6 and the side wall of the diversion well frame 1 are fixedly installed with a first torsion spring 21. The wheel body A plurality of water storage frames 22 are arranged circumferentially on 12, and one end of the water storage frame 22 is open, and the open end of the water storage frame 22 corresponds to the bent pipe 9. A first push rod 23, a second push rod 24, and a third push rod 25 are fixedly installed on the water storage frame 22, respectively. When the first torsion spring 21 and the second torsion spring 27 are not subjected to torsion, the position of the water storage frame 22 below the first push rod 23 is opposite to the outlet of the bent pipe 9, and the widths of the first push rod 23, the second push rod 24, and the third push rod 25 gradually increase.

[0025] In this embodiment, on sunny days, the first torsion spring 21 and the second torsion spring 27 are not subjected to torsion, the outlet of the curved pipe 9 is always aligned with the water storage frame 22 below the first push rod 23, and the sewage area maintains normal sewage water flow between the sewage inlet pipe 3 and the sewage outlet pipe 10. When it rains suddenly, the pollutants on the ground flow into the diversion well with the flushing of the initial rain. The pollutants mixed in the initial rain make the concentration of the pollutants in the initial rain relatively large. Therefore, it is necessary to discharge the initial rain to the sewage area. After the sudden rain, the initial rain will first wet the surface and then wet the pipe. The inner wall, and then the excess rainwater will flow out from the rainwater inlet pipe 4. In this embodiment, the rainwater inlet pipe 4 is connected by a curved pipe 9 to directly guide the initial rain to the curved pipe 9. At this time, the curved pipe 9 is facing the water storage frame 22. When the water storage frame 22 accumulates a certain amount of rainwater, the wheel body 12 will rotate, so that the initial rain can be directly discharged. While the wheel body 12 rotates, the curved pipe 9 is still continuously discharging water. When the wheel body 12 rotates, the first push rod 23, the second push rod 24, and the third push rod 25 successively push the curved pipe 9 to deflect, and as the amount of rain discharged from the rainwater inlet pipe 4 continues to increase , which causes the water-absorbing rubber ring 26 located at the outlet of the rainwater inlet pipe 4 to continuously absorb water. After the water-absorbing rubber ring 26 continuously absorbs water and expands, the water-absorbing rubber ring 26 fills the gap between the rainwater inlet pipe 4 and the curved pipe 9, thereby increasing the friction between the rainwater inlet pipe 4 and the curved pipe 9. Secondly, when rainwater flows out of the curved pipe 9, due to the gravity of rainwater, the flowing rainwater has a tendency to drive the curved pipe 9 to rotate to a vertical state. Therefore, under the action of the first push rod 23, the second push rod 24, the third push rod 25, the water-absorbing rubber ring 26, and the gravity of rainwater, the curved pipe 9 is driven to rotate. When the water inlet pipe 4 moves to a vertical state, all the rainwater will be discharged into the rainwater area. If it rains again in a short time, the water-absorbing rubber ring 26 has not lost water and is still in a state of close fit with the elbow 9. Therefore, the rainwater is still discharged into the rainwater area. When it has not rained for a long time, the water-absorbing rubber ring 26 gradually loses water, and the friction between the rainwater inlet pipe 4 and the elbow 9 is reduced. At this time, under the action of the second torsion spring 27, the elbow 9 rotates back to its original position, waiting for the next rainfall, and again directing the initial rain to the sewage area and discharging it to the sewage treatment plant for treatment.

[0026] See also Figure 5 In one embodiment, a ring sleeve 14 is fixedly mounted on the diversion well frame 1 , and the ring sleeve 14 is coaxially arranged with the rotating shaft 6 , and the ring sleeve 14 is rotatably connected with the rotating shaft 6 .

[0027] In this embodiment, a sliding ring 20 is rotatably provided on the ring sleeve 14 , and the sliding ring 20 is fixedly connected to the rotating shaft 6 . By providing the ring sleeve 14 , the wheel body 12 can be stably rotated.

[0028] See also Figure 2 , Figure 3 , Figure 4 In one embodiment, a clearance groove 15 is provided on the partition plate 13 at a position corresponding to the bent pipe 9 .

[0029] In this embodiment, the clearance groove 15 is provided to allow the bent pipe 9 to make way during the rotation process.

[0030] See also Figure 2 , Figure 3 , Figure 4 In one embodiment, a baffle 18 is slidably connected to one side of the partition 13 located in the rainwater area, and the baffle 18 is located directly below the clearance groove 15. A floating plate 19 is fixedly installed on one end of the baffle 18 away from the clearance groove 15.

[0031] In this embodiment, as the rain continues to be discharged, the rainfall tends to be smaller. Although the rainfall is decreasing, it is not necessary to discharge the rainwater into the sewage area at this time. Therefore, the continuous entry of rainwater into the rainwater area causes the position of the floating plate 19 to rise, and after rising, it drives the baffle 18 to move. The baffle 18 moves to close the give way groove 15, thereby preventing the curved pipe 9 from rotating into the sewage area.

[0032] See also Figure 2 , Figure 3 , Figure 4 In one embodiment, a floating rod 16 is slidably mounted on the inner wall of the rainwater area, a warning plate 17 is fixedly mounted on one end of the floating rod 16 away from the water surface, and a slide groove 7 corresponding to the warning plate 17 is opened on the cover plate 8.

[0033] In this embodiment, it can be known that rainwater is different from sewage, and the silt in rainwater cannot be filtered out. The soil on the ground has been completely dissolved in the rainwater after being washed by rainwater. In order to speed up the discharge of rainwater, it is impossible to set a filtering device that can filter out the silt. Therefore, the rainwater discharged from the rainwater inlet pipe 4 still contains a large amount of silt. In the present invention, the rainwater outlet pipe 11 is set at a certain distance from the bottom of the diversion well, so that the silt can be retained by the distance set at the bottom. Long-term and large-scale discharge of silt will cause the riverbed to rise, thereby polluting the water body and reducing the living space of aquatic organisms. Therefore, in this embodiment, by intercepting part of the silt in the diversion well, the discharged silt can be further reduced. In this embodiment, after rainwater enters the rainwater area, the float rod 16 will rise, and then the rainwater will settle in the rainwater area, and the silt will be located at the bottom. In the dry season, the float plate 19 will descend and fit the silt. When there is no silt in the rainwater area, the float plate 19 will descend to fit the bottom of the diversion well. At this time, one end of the warning plate 17 is inserted into the slide groove 7 and is flush with the surface of the cover plate 8. When silt exists, the float plate 19 descends to fit the silt. At this time, the warning plate 17 will extend out of the cover plate 8. The surface of the warning plate 17 can be sprayed with a striking color for warning.

[0034] See also Figure 2 , Figure 3 , Figure 4 In one embodiment, the warning plate 17 is provided with scale lines.

[0035] In this embodiment, by providing scale lines, the depth of silt in the rainwater area can be read, so that it is convenient for the staff to take corresponding measures.

[0036] See also Figure 2 , Figure 3 , Figure 4 In one embodiment, a sludge pipe 2 is provided in the rainwater area, and one end of the sludge pipe 2 is connected to a sludge pump.

[0037] In this embodiment, the sludge pipe 2 is provided so that the sludge can be cleaned when sludge suction is required.

[0038] See also Figure 1 , Figure 6 In one embodiment, a fixing rod 5 is fixedly mounted on one end of the rotating shaft 6 away from the wheel body 12 .

[0039] In this embodiment, a fixing rod 5 is provided so that the fixing rod 5 can be driven to rotate while the wheel body 12 rotates. The water storage frame 22 on the wheel body 12 will rotate due to the initial rain filling. When the curved pipe 9 is rotated to a vertical state, the water storage frame 22 will rotate in the opposite direction. Therefore, the corresponding fixing rod 5 also exhibits reciprocating rotation. When the fixing rod 5 is rotated to the maximum angle, the two ends of the fixing rod 5 are respectively in contact with the rainwater inlet pipe 4 and the sewage inlet pipe 3, thereby knocking the rainwater inlet pipe 4 and the sewage inlet pipe 3, so that the dirt deposited on the surface of the rainwater inlet pipe 4 and the sewage inlet pipe 3 can be separated from the pipe wall, thereby avoiding the blockage of the rainwater inlet pipe 4 and the sewage inlet pipe 3 under long-term use.

[0040] The working principle of the present invention is as follows: on sunny days, the outlet of the curved pipe 9 is always aligned with the water storage frame 22 below the first push rod 23, and the sewage area maintains normal sewage water flow between the sewage inlet pipe 3 and the sewage outlet pipe 10. When it rains suddenly, the rainwater inlet pipe 4 is connected through the curved pipe 9 to directly guide the initial rain to the curved pipe 9. At this time, the curved pipe 9 is facing the water storage frame 22. When the water storage frame 22 accumulates a certain amount of rainwater, the wheel body 12 will rotate, so that the initial rain can be directly discharged. During the rotation of the wheel body 12, the curved pipe 9 is still continuously discharging water. When the wheel body 12 rotates, the first push rod 23, the second push rod 24, and the third push rod 25 successively push the curved pipe 9 to deflect. As the amount of rain discharged from the rainwater inlet pipe 4 continues to increase, the water-absorbing rubber ring 26 located at the outlet of the rainwater inlet pipe 4 continues to absorb water. After the water-absorbing rubber ring 26 continues to absorb water and expands, the water-absorbing rubber ring 26 fills the gap between the rainwater inlet pipe 4 and the curved pipe 9, thereby increasing the amount of rain. The friction between the water inlet pipe 4 and the curved pipe 9, and secondly, when rainwater flows out of the curved pipe 9, due to the gravity of rainwater, the flowing rainwater has a tendency to drive the curved pipe 9 to rotate to a vertical state. Therefore, under the action of the first push rod 23, the second push rod 24, the third push rod 25, the water-absorbing rubber ring 26, and the gravity of rainwater, the curved pipe 9 is driven to rotate to a vertical state. At this time, all the rainwater will be discharged to the rainwater area. As the water level of the rainwater rises, the floating plate 19 moves up to block the groove 15, so that the curved pipe 9 is always located in the rainwater area. After the rain stops, after an interval of time, the interval here is to avoid raining again after the rain stops and to give the water-absorbing rubber ring 26 time to lose water, and then the curved pipe 9 returns to its original position under the action of the second torsion spring 27, waiting for the next rainfall. After a long period of drought, the silt depth inside the rainwater area can be judged according to the position of the warning plate 17, so that the silt can be cleaned through the silt pump and the silt pipe 2.
