Description

Technical Field

[0001] This application relates to the technical field of urban drainage, and specifically relates to a diversion structure for urban drainage. Background Art

[0002] With the development of the economy and the enhancement of environmental protection awareness, water resources are becoming increasingly precious. In order to make better use of rainwater resources, China implements a drainage method in which rainwater and sewage each use a separate municipal drainage pipe, that is, rainwater-sewage diversion. That is, a part of the sewage from balconies, roofs, etc. of each residential community is connected to the municipal pipe network through balcony risers and building exterior wall pipes. This part of the water is basically domestic sewage such as laundry water on sunny days. However, in rainy days, the rainwater passing through this drainage pipe is often clean rainwater later. The water that the city needs to treat is divided into two types: natural rainwater and urban sewage. Natural rainwater has little pollution and can be directly discharged into the urban river system. Urban sewage has high pollution. Directly discharging it into the river will cause pollution, and it needs to be collected into the sewage treatment system and undergo certain treatment before it can be discharged. And when it rains, rainwater will also enter the sewage collection system. Since rainwater does not need to be treated, flowing into the sewage treatment system will increase the treatment cost. Rainwater-sewage diversion is a drainage system that refers to separating rainwater and sewage and transporting them through separate pipes for discharge or subsequent treatment. Rainwater can be directly discharged into the river through the rainwater pipe network. Sewage needs to be collected through the sewage pipe network and then sent to the sewage treatment plant for treatment. After the water quality meets the standards, it is discharged into the river again. This can prevent the river from being polluted.

[0003] A prior patent (publication number: CN217759158U) discloses a diversion structure for urban drainage, including a catch well. A switching well is arranged at the bottom of the catch well. The upper end of the catch well is open, and an inlet grille is inserted and fixed in the upper end opening of the catch well. A sewage discharge pipe and a rainwater direct discharge pipe are arranged at the bottom of the catch well. The upper end of the sewage discharge pipe is flush with the bottom of the catch well. By arranging the sewage discharge pipe and the rainwater direct discharge pipe, when the rainwater is excessive, a large amount of later rainwater is directly discharged through the rainwater direct discharge pipe. When the rainwater decreases, the liquid level in the catch well drops, the floating cylinder resets, and the flow regulating valve is driven to reset through the linkage mechanism, and the upper end of the rainwater direct discharge pipe is blocked again.

[0004] The above-mentioned comparative document points out that this device discharges a small amount of rainwater into the sewage treatment system through the sewage discharge pipe, effectively reducing the amount of rainwater directly entering the sewage treatment system and reducing the pressure on the sewage treatment system. And it is triggered automatically throughout the process without the need for control, with a simple and reliable structure and low manufacturing and maintenance costs. However, the linkage mechanism includes multiple parts, such as an upper piston rod, a lower piston rod, and a gear-rack transmission pair. These devices not only increase the complexity of the system but also may lead to difficult maintenance and an increased risk of failures. Utility Model Content

[0005] In response to the shortcomings of the prior art, the present application provides a diversion structure for urban drainage, which has the advantages of reducing maintenance and extending the life of the device. It solves the problem that the linkage mechanism includes multiple parts, such as an upper piston rod, a lower piston rod, and a rack and pinion transmission pair. These devices not only increase the complexity of the system, but may also cause maintenance difficulties and increase the risk of failure.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a diversion structure for urban drainage, including a water collecting pipe, a rainwater straight discharge pipe is fixedly connected to the inside of the water collecting pipe, three fixing seats are fixedly connected to the upper end of the outer wall of the rainwater straight discharge pipe, the upper ends of the three fixing seats are penetrated by through holes, the insides of the three through holes are fixedly connected with sliding rods, and the upper ends of the three sliding rods are fixedly connected to floating plates.

[0007] The outer wall of the rainwater straight discharge pipe is rotatably connected with a baffle, the bottom end of the floating plate is fixedly connected with three first ball seats, the upper end of the baffle is fixedly connected with three second ball seats, and ball head connecting rods are ball-connected between the three first ball seats and the second ball seats.

[0008] Through the above scheme, through the arrangement of the first ball seat, the second ball seat, the ball head connecting rod and the baffle, when the water level in the water collecting pipe rises, the float plate rises with the water level, thereby opening the channel of the rainwater direct discharge pipe, so that rainwater can be directly discharged through the rainwater direct discharge pipe. While the float plate rises, the rising force of the float plate is converted into a rotational force through the inclined connecting rod, thereby rotating the baffle plate to reduce the speed at which rainwater enters the sewage discharge device, so that the accumulation speed of rainwater in the water collecting well is accelerated, so that a large amount of later rainwater is directly discharged through the rainwater direct discharge pipe. The device can effectively divert rainwater and sewage, avoid rainwater directly entering the sewage treatment system, thereby reducing the burden on the sewage treatment system, saving energy, and being beneficial to environmental protection.

[0009] Furthermore, the bottom ends of the three sliding rods are fixedly connected to a limiting plate.

[0010] Through the above solution, the setting of the limiting plate is used to limit the position of the sliding rod to prevent the sliding rod from escaping from the through hole.

[0011] Furthermore, water outlets are provided at the bottom end of the water collecting pipe and the upper end of the baffle.

[0012] Through the above solution, the outlet pipe is used to allow sewage to flow out of the collecting pipe.

[0013] Furthermore, the bottom end of the water collecting pipe is fixedly connected to a water outlet pipe, and the bottom end of the water outlet pipe is fixedly connected to a bottom plate.

[0014] Through the above scheme, the box body composed of the outlet pipe and the bottom plate is used to collect sewage inside.

[0015] Furthermore, one side of the bottom end of the bottom plate is fixedly connected with a sewage pipe.

[0016] Through the above solution, the sewage collected inside the box formed by the water outlet pipe and the bottom plate is discharged through the sewage pipe.

[0017] Furthermore, a fence is fixedly connected to the upper end of the water collecting pipe, and a water draining cover is fixedly connected to the upper end of the fence.

[0018] Through the above solution, the water draining cover is used to prevent sundries from entering the inside of the water collecting pipe.

[0019] Furthermore, the floating plate is slidably arranged inside the water collecting pipe.

[0020] Through the above solution, the floating plate can slide through the sliding rod in the through hole, and thus can slide inside the water collecting tank.

[0021] Furthermore, the baffle is rotatably arranged inside the water collecting pipe.

[0022] Through the above solution, the baffle rotates inside the water collecting pipe to adjust the speed of sewage discharge.

[0023] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0024] For the diversion structure for urban drainage, through the settings of the first ball seat, the second ball seat, the ball head connecting rod and the baffle, when the water level in the water collecting pipe rises, the floating plate rises with the water level, thereby opening the channel of the rainwater direct discharge pipe, so that the rainwater can be directly discharged through the rainwater direct discharge pipe. While the floating plate is rising, the force of the rising floating plate is converted into a rotating force through the inclined connecting rod, and then the baffle rotates to reduce the speed of rainwater entering the sewage discharge device, so that the accumulation speed of rainwater in the catch basin increases, and a large amount of later rainwater is directly discharged through the rainwater direct discharge pipe. This device can effectively separate rainwater and sewage, avoid rainwater from directly entering the sewage treatment system, thereby reducing the burden on the sewage treatment system, saving energy, and being beneficial to environmental protection.

[0032] Please refer to Figure 1 , Figure 2 and Figure 3 In this embodiment, a diversion structure for urban drainage includes a collector pipe 1. Inside the collector pipe 1, a rainwater direct discharge pipe 2 is fixedly connected. The rainwater direct discharge pipe 2 is used to directly discharge the later rainwater. At the upper end of the outer wall of the rainwater direct discharge pipe 2, three fixed seats 3 are fixedly connected. Through holes 4 are provided through the upper ends of the three fixed seats 3. Slide bars 5 are fixedly connected inside the three through holes 4. The upper ends of the three slide bars 5 are fixedly connected to a floating plate 6. The arrangement of the through holes 4 and the slide bars 5 enables the floating plate 6 to move up and down smoothly. The outer wall of the rainwater direct discharge pipe 2 is rotatably connected to a baffle 8. At the bottom end of the floating plate 6, three first ball seats 9 are fixedly connected. At the upper end of the baffle 8, three second ball seats 10 are fixedly connected. Ball head connecting rods 11 are ball-jointed between the three first ball seats 9 and the second ball seats 10. The ball head connecting rods 11 are used to connect the first ball seats 9 and the second ball seats 10.

[0033] Please refer to Figure 3 and Figure 4 At the bottom ends of the three slide bars 5, limit plates 7 are fixedly connected. The limit plates 7 are arranged to limit the positions of the slide bars 5 and prevent the slide bars 5 from disengaging from the through holes 4. Water outlets 12 are provided at the bottom end of the collector pipe 1 and the upper end of the baffle 8. An outlet pipe 13 is used to allow sewage to flow out of the collector pipe 1. The bottom end of the collector pipe 1 is fixedly connected to an outlet pipe 13. The bottom end of the outlet pipe 13 is fixedly connected to a bottom plate 14. The box body formed by the outlet pipe 13 and the bottom plate 14 is used to collect sewage inside. On one side of the bottom end of the bottom plate 14, a sewage pipe 15 is fixedly connected. The sewage collected inside the box body formed by the outlet pipe 13 and the bottom plate 14 is discharged through the sewage pipe 15.

[0034] Please refer to Figure 1 and Figure 3, a retaining wall 16 is fixedly connected to the upper end of the water collecting pipe 1, a water draining cover 17 is fixedly connected to the upper end of the retaining wall 16, and the water draining cover 17 is used to prevent sundries from entering the interior of the water collecting pipe 1. The floating plate 6 is slidably arranged inside the water collecting pipe 1. The floating plate 6 can slide in the through hole 4 through the sliding rod 5, and thus can slide inside the water collecting tank. The baffle 8 is rotatably arranged inside the water collecting pipe 1. The baffle 8 rotates inside the water collecting pipe 1 to adjust the speed of sewage discharge.

[0035] In this embodiment, for the diversion structure for urban drainage, through the settings of the first ball seat 9, the second ball seat 10, the ball head connecting rod 11 and the baffle 8, when the water level in the water collecting pipe 1 rises, the floating plate 6 rises with the water level, thereby opening the channel of the rainwater direct discharge pipe 2, so that the rainwater can be directly discharged through the rainwater direct discharge pipe 2. While the floating plate 6 is rising, the force of the rising floating plate 6 is converted into a rotational force through the obliquely arranged connecting rod, and then the baffle 8 rotates to reduce the speed of rainwater entering the sewage treatment device, so that the accumulation speed of rainwater in the catch basin increases, and a large amount of later rainwater is directly discharged through the rainwater direct discharge pipe 2. This device can effectively separate rainwater and sewage, avoid rainwater from directly entering the sewage treatment system, thereby reducing the burden on the sewage treatment system, saving energy, and being beneficial to environmental protection.

[0036] It should be noted that the three first ball seats 9 and the second ball seats 10 are arranged staggeredly and are connected by the ball head connecting rod 11.

[0037] The working principle of the above embodiment is as follows:

[0038] When in use, when the device is not affected by the water flow, the floating plate 6 is at a lower position in the water collecting pipe 1, and the baffle 8 may be in a partially open state. As the floating plate 6 rises, through the three first ball seats 9 fixed to the bottom end of the floating plate 6, the ball head connecting rod 11 starts to tilt. This tilting force is transmitted to the three second ball seats 10 fixed to the upper end of the baffle 8 through the ball head connecting rod 11. Subject to the force transmitted by the ball head connecting rod 11, the baffle 8 starts to rotate inside the water collecting pipe 1. This rotation causes the water outlet 12 at the upper end of the baffle 8 to gradually close. As the floating plate 6 continues to rise, when the floating plate 6 rises to a certain position, the rainwater can be directly discharged through the rainwater direct discharge pipe 2 without passing through the bottom of the water collecting pipe 1, and thus is separated from the sewage and rainwater.
