Description

Technical Field

[0001] This invention relates to the field of drainage pipe technology, specifically to a rainwater and sewage separation drainage pipe. Background Technology

[0002] Separate sewer systems are drainage systems that connect sewage pipes and rainwater pipes. They are designed to alter downstream discharge patterns during rainfall. During the dry season and early rainfall periods, urban sewage typically contains more impurities and needs to flow through sewage pipes to wastewater treatment plants for filtration before being discharged into the ecosystem. Later rainfall periods, with fewer impurities, can be directly discharged into lakes and rivers through rainwater pipes, reducing the burden on wastewater treatment plants.

[0003] A search revealed a Chinese patent with authorization number CN218643497U, which discloses a rainwater and sewage separation drainage pipe. The rainwater and sewage separation drainage pipe is horizontally arranged, with fixing lugs fixedly connected to both sides. A partition is fixedly connected to the middle of the interior of the rainwater and sewage separation drainage pipe. Rainwater flows above the partition, sewage flows below the partition, and a filter screen is fixedly connected to the top of the partition.

[0004] The aforementioned patented rainwater and sewage separation drainage pipe has the following shortcomings: it uses a filter screen to filter rainwater and sewage, but it cannot quickly remove impurities and filth. Long filtration cycles can easily lead to blockages, making it difficult to guarantee filtration effectiveness. Existing technology requires stopping the entire pipeline drainage and then removing the impurities from the inlet, which is time-consuming and labor-intensive, increasing maintenance costs for operators and significantly reducing the efficiency of the separation drainage. Therefore, a corresponding technical solution needs to be designed to address these issues. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a rainwater and sewage separation drainage pipe, which solves the technical problems.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a rainwater and sewage diversion drainage pipe, including a rainwater and sewage diversion box, a filter adjustment structure, a cleaning position shielding mechanism and a limiting shielding mechanism, wherein the front and rear ends of the rainwater and sewage diversion box are fixedly connected to a drainage pipe adapter pipe one and a drainage pipe adapter pipe two, and the outer ends of the drainage pipe adapter pipe one and the drainage pipe adapter pipe two are respectively fixedly connected to an inlet extension pipe and an outlet extension pipe.

[0007] A partition is fixedly installed in the middle of the interior of the rainwater and sewage separation box, and a through groove is opened in the middle of the partition.

[0008] The filter adjustment structure is rotatably connected to the upper middle of the rainwater and sewage diversion box, and the lower end of the filter adjustment structure is connected to the through groove.

[0009] The cleaning position shielding mechanism is respectively located at the upper and lower ends of both sides of the rainwater and sewage diversion box, and is used to disassemble and clean the internal dirt or impurities;

[0010] The limiting and shielding mechanism is connected through the upper and lower ends of the rainwater and sewage diversion box near the front, and is used to block rainwater.

[0011] Preferably, the first and second drain pipe adapters are outward-facing constricted structures, the inlet extension pipe and the outlet extension pipe are straight pipe structures, and support legs are fixedly distributed on both sides of the rainwater and sewage diversion box.

[0012] The outward-curving, tapered drain pipe connectors one and two not only ensure smooth fluid flow within the pipes but also facilitate connection with other drain pipes, improving the system's versatility and compatibility. The support legs provide stable support for the entire device, ensuring its stability in different installation environments and reducing the risk of damage caused by vibration or external forces.

[0013] Preferably, the filter adjustment structure includes an end plate, a fixed cylinder, an adjusting ring, a screw, a filter plate, and a fixed column. The end plate has pads fixedly provided at its bottom front and rear ends. The upper part of the pads is threadedly connected to the upper end of the rainwater and sewage diversion box. The fixed cylinder is fixedly provided in the middle of the end plate. The adjusting ring is rotatably connected to the upper end of the fixed cylinder. Extension rods are fixedly distributed on the outer side wall of the adjusting ring. The screw is connected through the inside of the adjusting ring.

[0014] The extension rod allows operators to easily rotate the adjustment ring by hand. When the adjustment ring is rotated, the screw will move up and down accordingly. The pad is used to install the end plate above the rainwater and sewage diversion box. The end plate passes through the fixing cylinder, which limits and stabilizes the sliding adjustment screw and the fixing column.

[0015] Preferably, the fixing column is fixedly disposed at the bottom of the screw and is connected through to the upper end of the rainwater and sewage diversion box. A support base is fixedly disposed at the bottom of the fixing column, and the filter plate is fixedly disposed at the bottom of the support base. Filter holes are distributed inside the filter plate.

[0016] The fixed column is used to drive the support base and filter plate to rise and fall, thereby moving the filter plate up and down and adjusting its position in the rainwater and sewage diversion box. The filter holes are used to filter and block dirt and impurities.

[0017] Preferably, a slot 1 is provided on the upper side of the rainwater and sewage diversion box, and a sealing slot 2 is provided on the outer end of the slot 1.

[0018] The upper side of the rainwater and sewage diversion box is provided with a second empty groove, and the outer end of the second empty groove is provided with a third sealing groove.

[0019] The lower interior of both the first and second empty slots has a rounded corner structure.

[0020] Empty slot one and empty slot two are used to fasten the inner plate inside the shielding plate. The shielding plate is used to install to sealing slot two or sealing slot three. The sealed installation prevents water leakage. The rounded corner structure is used to more smoothly clean impurities outward.

[0021] Preferably, the cleaning position blocking mechanism includes a blocking plate, a limiting slide rod, a positioning stake, a locking bolt, and a positioning cylinder. The limiting slide rod is fixedly distributed at the upper and lower ends of the outer side walls of the first and second empty slots, and the positioning stake is fixedly disposed at the front and rear ends of the outer side walls of the first and second empty slots.

[0022] Angle plate one is fixedly provided at the upper and lower ends of the outer side wall of the shield, and angle plate two is fixedly provided at the front and rear ends of the outer side wall of the shield.

[0023] The limiting slide bar and the positioning stake are respectively slidably connected inside corner plate one or corner plate two;

[0024] Both corner plate one and corner plate two are L-shaped plate structures;

[0025] The L-shaped plate structure of corner plate one and corner plate two allows them to slide outwards to the outside of the limiting slide rod and positioning stake.

[0026] Preferably, lifting devices are fixedly provided at both ends of the outer side wall of the baffle;

[0027] The positioning cylinder is fixedly installed on the front and rear ends of the outer side walls of the first and second empty slots, and the positioning cylinder is located at the inner end of the positioning pile. The locking bolt is threaded through and connected to the inside of the second corner plate.

[0028] The lifting device allows operators to easily hold and slide the baffle plate inside and out, reducing labor intensity and making operation simpler. It can greatly shorten cleaning time and improve the overall operating efficiency of the rainwater and sewage diversion drainage pipe. The locking bolt is used to insert into the positioning cylinder through the thread to tighten and lock the baffle plate to the inside of empty trough one and empty trough two.

[0029] Preferably, an elliptical groove is provided on the outer side of the positioning pile near its inner end;

[0030] An outer end of the second corner plate is provided with a through hole, a spring is fixedly provided at the outer end of the through hole, a fixed plate is fixedly provided at the outer end of the spring, a pull ring is fixedly provided at the outer end of the fixed plate, a positioning rod is fixedly provided at the inner end of the fixed plate, and the positioning rod is connected through the through hole.

[0031] The positioning rod is used for insertion and installation into the slot. The elliptical slot serves two purposes: firstly, it secures the positioning rod to prevent it from loosening; secondly, it supports the locking bolts, allowing for adjustment to tighten the baffle plate. Pulling the pull ring causes the positioning rod to move outward under the action of the spring, sliding to the appropriate position so that the positioning rod aligns with the slot. Releasing the pull ring allows the positioning rod to insert into the slot, thus positioning the baffle plate. Simultaneously, the locking bolts further enhance the baffle plate's fixation, preventing it from loosening during operation and ensuring its sealing performance during normal use, preventing rainwater and sewage leakage.

[0032] Preferably, the rainwater and sewage diversion box has an installation groove near the front of its upper and lower ends, a sealing groove at the upper end of the installation groove, and an installation hole at the corner of the sealing groove.

[0033] Mounting slot one is used to fix the mounting plate, sealing slot one is used to seal the mounting plate, and mounting hole is used to pass bolts through to lock the mounting plate.

[0034] Preferably, the limiting and blocking mechanism includes a sealing baffle, a fixed plate, a sealing plate, a rotating rod, a rotating disk, and a handle. The fixed plate is fixedly disposed at the bottom of the sealing plate, and a threaded cylinder is fixedly disposed at the middle of the upper end of the sealing plate. The rotating rod is rotatably connected to the inside of the threaded cylinder, and the sealing baffle is fixedly disposed at the bottom of the rotating rod.

[0035] The rotating disk is rotatably connected to the upper end of the rotating rod, and the handle is rotatably connected to the top end of the rotating disk;

[0036] When rainwater needs to be stopped, turn the handle to rotate the rotating disc and rotating rod. The threaded cylinder is used to stabilize and limit the rotation of the rotating rod, thereby rotating the sealing baffle to the appropriate position to block the flow of rainwater or open the flow. This ensures good sealing performance, effectively avoids rainwater leakage caused by poor sealing, and reduces the labor intensity of operators.

[0037] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0038] (1) By connecting the drain pipes 1 and 2, the inlet extension pipe and the outlet extension pipe to the front and rear ends of the rainwater and sewage diversion box, a stable channel is provided for the entry and exit of rainwater and sewage. The rainwater and sewage flow between the upper and lower layers through the partition inside the rainwater and sewage diversion box. The filter adjustment structure is connected by a rotating connection through the middle of the upper end of the rainwater and sewage diversion box, which makes it easy to manually rotate and adjust the position of the filter plate inside the rainwater and sewage diversion box to adapt to rainwater and sewage with different flow rates and impurity contents, thus improving the filtration effect. During the rainy season or when the sewage flow is large, the filter plate can be raised to increase the filtration area and effectively filter the upper rainwater channel. At the same time, during the dry season or when the sewage flow is small, the filter plate can be lowered to filter the lower sewage channel. It can effectively intercept impurities and particulate matter in sewage and prevent them from entering the rainwater pipe or sewage treatment plant, thus protecting the subsequent treatment equipment and natural water bodies. It can reduce the possibility of blockage while ensuring the filtration effect.

[0039] (2) By installing cleaning position shielding mechanisms on the upper and lower ends of both sides of the rainwater and sewage diversion box, the shielding plate can be flexibly installed and disassembled, which facilitates quick cleaning of dirt or impurities at the front end of the filter plate and achieves the purpose of accurately cleaning dirt in the rainwater or sewage channel.

[0040] (3) The installation slots at the upper and lower ends of the rainwater and sewage diversion box provide space for the installation of the limiting shielding mechanism, thereby achieving the cut-off of rainwater or sewage. Rainwater discharge or cut-off can be controlled at any time according to actual needs. When it is necessary to clean up dirt and impurities, the limiting shielding mechanism can be closed to stop rainwater and sewage in front. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0057] Please see Figures 1-11The present invention provides a technical solution: a rainwater and sewage diversion drainage pipe, including a rainwater and sewage diversion box 1, a filter adjustment structure 2, a cleaning position shielding mechanism 3 and a limiting shielding mechanism 4. The front and rear ends of the rainwater and sewage diversion box 1 are fixedly connected to a drainage pipe adapter pipe 11 and a drainage pipe adapter pipe 2 13. The outer ends of the drainage pipe adapter pipe 11 and the drainage pipe adapter pipe 2 13 are respectively fixedly connected to an inlet extension pipe 12 and an outlet extension pipe 14.

[0058] A partition 16 is fixedly installed in the middle of the interior of the rainwater and sewage separation box 1, and a through groove 161 is opened in the middle of the partition 16;

[0059] The filter adjustment structure 2 is rotatably connected to the upper middle of the rainwater and sewage diversion box 1, and the lower end of the filter adjustment structure 2 is connected to the through groove 161.

[0060] The cleaning position shielding mechanism 3 is respectively located on the upper and lower ends of both sides of the rainwater and sewage diversion box 1, and is used to disassemble and clean the internal dirt or impurities;

[0061] The limiting and shielding mechanism 4 is connected through the upper and lower ends of the rainwater and sewage diversion box 1 near the front, and is used to block rainwater.

[0062] Further improvements include outward-facing constricted structure for drain pipe connector 11 and drain pipe connector 2 13, straight pipe structure for inlet extension pipe 12 and outlet extension pipe 14, and fixed support legs 15 on both sides of the rainwater and sewage diversion box 1.

[0063] The outward-facing constricted drain pipe connector 11 and drain pipe connector 2 13 not only ensure smooth fluid flow within the pipe but also facilitate connection with other drain pipes, improving the system's versatility and compatibility. The support leg 15 provides stable support for the entire device, ensuring its stability in different installation environments and reducing the risk of damage caused by vibration or external forces.

[0064] Further improvements include an end plate 21, a fixed cylinder 212, an adjusting ring 22, a screw 23, a filter plate 24, and a fixed column 25. The end plate 21 has pads 211 fixedly installed at the front and rear ends of its bottom. The upper part of the pads 211 is threadedly connected to the upper end of the rainwater and sewage diversion box 1. The fixed cylinder 212 is fixedly installed in the middle of the end plate 21. The adjusting ring 22 is rotatably connected to the upper end of the fixed cylinder 212. An extension rod 221 is fixedly distributed on the outer wall of the adjusting ring 22. The screw 23 is connected through the interior of the adjusting ring 22.

[0065] The extension rod 221 facilitates the operator to manually rotate the adjusting ring 22. When the adjusting ring 22 is rotated, the screw 23 will move up and down accordingly. The pad block 211 is used to install the end plate 21 above the rainwater and sewage diversion box 1. The end plate 21 is used to pass through the fixed cylinder 212. The fixed cylinder 212 is used to limit and stabilize the sliding adjusting screw 23 and the fixed column 25.

[0066] In a further improvement, the fixing column 25 is fixedly installed at the bottom of the screw 23 and is connected through to the upper end of the rainwater and sewage diversion box 1. The bottom of the fixing column 25 is fixedly provided with a support base 242, and the filter plate 24 is fixedly installed at the bottom of the support base 242. Filter holes 241 are distributed inside the filter plate 24.

[0067] The fixed column 25 is used to drive the support base 242 and the filter plate 24 to rise and fall, and to move the filter plate 24 up and down to adjust its position in the rainwater and sewage diversion box 1. The filter holes 241 are used to filter and block dirt and impurities.

[0068] Further improvements include a hollow groove 18 on the upper side of one side of the rainwater and sewage separation box 1, and a sealing groove 181 on the outer end of the hollow groove 18.

[0069] A second empty groove 19 is provided on the upper end of the other side of the rainwater and sewage separation box 1, and a third sealing groove 191 is provided on the outer end of the second empty groove 19.

[0070] The lower interior of slot 18 and slot 29 has a rounded corner structure.

[0071] Empty slot 18 and empty slot 2 19 are used to fasten the inner plate inside the shield 31. The shield 31 is used to be installed at the sealing slot 2 181 or sealing slot 3 191. The sealing installation prevents water leakage. The rounded corner structure is used to more smoothly clean impurities outward.

[0072] Further improvements include a baffle plate 31, a limiting slide bar 33, a positioning stake 35, a locking bolt 36, and a positioning cylinder 37. The limiting slide bar 33 is fixedly distributed on the upper and lower ends of the outer side walls of the first slot 18 and the second slot 19, and the positioning stake 35 is fixedly installed on the front and rear ends of the outer side walls of the first slot 18 and the second slot 19.

[0073] Angle plate 32 is fixedly provided at the upper and lower ends of the outer side wall of the shielding plate 31, and angle plate 34 is fixedly provided at the front and rear ends of the outer side wall of the shielding plate 31.

[0074] The limiting slide bar 33 and the positioning stake 35 are respectively slidably connected inside the corner plate 32 or the corner plate 34;

[0075] Both corner plate 1 (32) and corner plate 2 (34) are L-shaped plate structures;

[0076] The L-shaped plate structure of corner plate 32 and corner plate 34 allows them to slide outwards to the outside of the limiting slide bar 33 and the positioning post 35.

[0077] Further improved, lifting devices 38 are fixedly provided at both ends of the outer side wall of the baffle 31;

[0078] The positioning cylinder 37 is fixedly installed on the front and rear ends of the outer side walls of the first slot 18 and the second slot 19, and the positioning cylinder 37 is located at the inner end of the positioning pile 35. The locking bolt 36 is threaded through and connected to the inside of the second angle plate 34.

[0079] The lifting device 38 allows operators to easily hold and adjust the inner and outer sliding baffle 31, reducing labor intensity and making operation simpler. It can greatly shorten cleaning time and improve the overall operating efficiency of the rainwater and sewage diversion drainage pipe. The locking bolt 36 is used to insert into the positioning cylinder 37 through the thread to fasten and lock the baffle 31 to the inside of the empty slot 18 and the empty slot 2 19.

[0080] Further improvements include an elliptical groove 351 located near the inner end of the outer side of the positioning pile 35;

[0081] Angle plate 2 34 has a through hole 341 at its outer end, a spring 391 is fixedly installed at the outer end of the through hole 341, a fixed plate 392 is fixedly installed at the outer end of the spring 391, a pull ring 393 is fixedly installed at the outer end of the fixed plate 392, and a positioning rod 39 is fixedly installed at the inner end of the fixed plate 392. The positioning rod 39 is connected through the through hole 341.

[0082] The positioning rod 39 is used to insert and install into the slot 351. The slot 351, which has an elliptical structure, serves two purposes: firstly, to hold the positioning rod 39 in place to prevent it from loosening; and secondly, to support the locking bolt 36 for adjusting its position to secure the baffle plate 31. Pulling the pull ring 393 causes the positioning rod 39 to move outward under the action of the spring 391, sliding it to the appropriate position so that the positioning rod 39 aligns with the slot 351. Releasing the pull ring 393 allows the positioning rod 39 to insert into the slot 351, thus positioning the baffle plate 31. At the same time, the locking bolt 36 further enhances the fixing effect of the baffle plate 31, preventing it from loosening during operation and ensuring the sealing of the baffle plate 31 during normal use, preventing rainwater and sewage leakage.

[0083] Further improvements include the installation groove 17 being provided near the front of the upper and lower ends of the rainwater and sewage separation box 1, the sealing groove 171 being provided at the upper end of the installation groove 17, and the installation hole 172 being provided at the corner of the sealing groove 171.

[0084] Mounting groove 17 is used to fix the mounting plate 42, sealing groove 171 is used to seal the mounting plate 43, and mounting hole 172 is used to pass bolts through to lock the mounting plate 43.

[0085] Specifically, the limiting and blocking mechanism 4 includes a sealing baffle 41, a fixing plate 42, a sealing plate 43, a rotating rod 44, a rotating disk 45, and a handle 46. The fixing plate 42 is fixedly disposed at the bottom of the sealing plate 43. A threaded cylinder 431 is fixedly disposed at the middle of the upper end of the sealing plate 43. The rotating rod 44 is rotatably connected to the inside of the threaded cylinder 431. The sealing baffle 41 is fixedly disposed at the bottom of the rotating rod 44.

[0086] The rotating disk 45 is rotatably connected to the upper end of the rotating rod 44, and the handle 46 is rotatably connected to the top end of the rotating disk 45.

[0087] When it is necessary to stop rainwater, turn the handle 46 to drive the rotating disk 45 and the rotating rod 44 to rotate. The threaded cylinder 431 is used to stabilize and limit the rotation of the rotating rod 44, thereby causing the sealing baffle 41 to rotate to a suitable position to block the flow of rainwater or open the flow. This can ensure good sealing performance, effectively avoid rainwater leakage caused by poor sealing, and reduce the labor intensity of operators.

[0088] Working principle: The inlet extension pipe 12 and the outlet extension pipe 14 are connected to other drainage pipes respectively. The outward-curving drain pipe adapter 11 and drain pipe adapter 2 13 ensure smooth flow of fluid in the pipe.

[0089] Multiple support legs 15 firmly support the rainwater and sewage separation box 1 on the ground, providing stable support for the entire device and reducing the risk of damage caused by vibration or external forces.

[0090] During the rainy season or when sewage flow is high, rainwater or sewage enters the rainwater and sewage diversion box 1 through the inlet extension pipe 12. The upper and lower layers are separated by the partition 16. By holding the extension rod 221 and rotating the adjusting ring 22, the screw 23 moves up and down. The screw 23 drives the fixed column 25, the support base 242 and the filter plate 24 to adjust the position of the filter plate 24 in the rainwater and sewage diversion box 1. The filter plate 24 filters and blocks dirt and impurities through the filter holes 241 inside the filter plate 24. After being filtered by the filter plate 24, the clean water flows out through the outlet extension pipe 14, while dirt and impurities are blocked in front of the filter plate 24. Raising the filter plate 24 increases the filtration area and effectively filters the upper channel.

[0091] Similarly, during the dry season or when the sewage flow is low, the filter plate 24 can be lowered to filter the lower channel, effectively intercepting impurities and particulate matter in the sewage and preventing them from entering the rainwater pipes or sewage treatment plants.

[0092] When it is necessary to clean the dirt and impurities inside the rainwater and sewage diversion box 1, stop the flow of the drain pipe, rotate the handle 46 by hand, drive the rotating disk 45 and the rotating rod 44 to rotate, so that the sealing baffle 41 rotates to the appropriate position to seal and block the flow of rainwater and sewage.

[0093] First, loosen the locking bolt 36, then pull the pull ring 393 to make the positioning rod 39 move outward under the action of the spring 391, so that it leaves the slot 351. Hold the lifting device 38 to slide the cover plate 31 outward. The corner plate 1 32 and corner plate 2 34 on the outer side wall of the cover plate 31 slide and disassemble along the limiting slide rod 33 and the positioning post 35 respectively.

[0094] Clean the dirt and impurities in front of the filter plate 24, reverse the above steps, reinstall the baffle plate 31 back in its original position, and tighten the locking bolts 36.

[0095] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
