Description

Technical Field

[0001] This application relates to civil engineering, and in particular to a corrosion-resistant composite compartmentalized municipal drainage structure. Background Technology

[0002] Municipal drainage structures are a core component of urban water cycle systems, undertaking the tasks of collecting, transporting, and discharging rainwater, domestic sewage, and some industrial wastewater. Their stability is directly related to urban flood control safety, the quality of the living environment, and the long-term operation of infrastructure. Currently, most municipal drainage systems achieve water flow transmission through a single cavity and rely on an overall anti-corrosion coating to protect the structure in order to cope with water erosion and the erosion of mild corrosive media.

[0003] Most existing drainage structures do not have clearly defined chambers for water flow treatment processes. Functions such as filtration, transportation, and corrosion resistance are concentrated in one area, and corrosion protection is mostly integrated. This design means that when the local anti-corrosion layer is damaged by impurities or water flow impact, corrosive media will directly erode the main structure, causing problems such as leakage and reduced strength. This not only shortens the life of the structure but also increases maintenance costs and frequency.

[0004] To address the aforementioned issues, this application innovatively proposes a corrosion-resistant composite compartmentalized municipal drainage structure. By independently setting up three functional compartments—a pretreatment compartment, a corrosion-resistant isolation compartment, and a main drainage compartment—a stepped treatment process of impurity interception, corrosion isolation, and transportation is formed. The three compartments work together to achieve functional zoning, and the targeted protection of the corrosion-resistant isolation compartment enhances the overall corrosion resistance, effectively solving the problems of traditional structures. Utility Model Content

[0005] The purpose of this application is to provide a corrosion-resistant composite compartmentalized municipal drainage structure, which has the advantage of strong corrosion resistance and solves the problem of poor corrosion resistance in existing technologies.

[0006] The corrosion-resistant composite compartmentalized municipal drainage structure provided in this application adopts the following technical solution: it includes a pretreatment chamber, a corrosion-resistant isolation chamber and a main drainage chamber. The corrosion-resistant isolation chamber is fixedly installed at the bottom of the pretreatment chamber by studs. The main drainage chamber is fixedly installed at the bottom of the corrosion-resistant isolation chamber by studs. The top of the pretreatment chamber is provided with a cover plate by studs. Two sets of water inlet pipes are provided on the top of the cover plate.

[0007] By adopting the above technical solution, the pretreatment chamber, anti-corrosion isolation chamber and main drainage chamber are fixed with studs to form a compartmentalized structure, realizing the functional zoning of the drainage process. This allows the pretreatment, anti-corrosion isolation and main drainage functions to be independent yet coordinated, avoiding the problem of insufficient corrosion resistance caused by the mixed functions of traditional single chambers. The overall corrosion resistance and operational stability of the drainage structure are improved, and each chamber is installed independently, which facilitates individual maintenance and replacement.

[0008] Preferably, guide plates are provided on both sides of the inner wall of the pretreatment chamber, and grooves are provided on both sides of the inner wall of the pretreatment chamber, with the same filter component provided in both sets of grooves.

[0009] By adopting the above technical solution, a guide plate and a filter assembly in the groove are set on the inner wall of the pretreatment chamber. The guide plate can reduce the impact of water flow turbulence on the chamber, and the filter assembly can perform preliminary filtration of the incoming water flow, intercept impurities, reduce the wear of the subsequent anti-corrosion isolation chamber and main drainage chamber caused by impurities, and ensure the service life of the overall structure.

[0010] Preferably, the filter assembly includes two connecting blocks and two mounting blocks. The two connecting blocks are slidably connected in two grooves. A lead screw is mounted on the bottom of one connecting block via a rotating shaft. The shaft end of the lead screw is mounted on a mounting block via a rotating shaft. The two mounting blocks are slidably connected in two grooves. A threaded block is threadedly connected to the surface of the lead screw. A slide rod is mounted on the bottom of the other connecting block. A slider is slidably connected to the surface of the slide rod. A grid plate is provided between the slider and the threaded block. A filter plate is provided between the two mounting blocks. A knob is mounted on the top of one connecting block. The knob is fixedly connected to the shaft end of the lead screw via a rotating shaft.

[0011] By adopting the above technical solution, the filter assembly uses a structure of lead screw, threaded block, slide bar, and slider in conjunction with the grid plate and filter plate. The position of the grid plate can be adjusted by turning the lead screw with a knob, which makes it easy to adjust the filter gap according to the impurity content of the water flow and improve the adaptability of the filter. At the same time, the connecting block and the mounting block are slidably connected in the groove, which makes the grid plate and filter plate easy to disassemble, clean or replace, reducing the difficulty of maintenance and ensuring long-term stable filtration effect.

[0012] Preferably, the corrosion-resistant isolation cavity is provided with a polytetrafluoroethylene plate, a fiberglass mesh, and a main frame from the inside to the outside. Epoxy resin adhesive is provided between the polytetrafluoroethylene plate and the fiberglass mesh and between the fiberglass mesh and the main frame. Three sets of arc-shaped platforms are provided inside the corrosion-resistant isolation cavity.

[0013] By adopting the above technical solution, the corrosion-resistant isolation cavity adopts a layered structure of polytetrafluoroethylene (PTFE) plate, fiberglass mesh, and main frame, with the layers bonded together by epoxy resin adhesive. The PTFE plate directly contacts the corrosive medium, blocking the corrosion path with its corrosion resistance. The fiberglass mesh enhances the crack resistance of the interlayer connection, offsets the deformation stress of different materials, and avoids interlayer cracking and leakage. The main frame provides structural support, and the internal arc-shaped platform guides the water flow smoothly, reducing turbulent impact, further improving the corrosion resistance, durability, and structural stability of the corrosion-resistant isolation cavity.

[0014] Preferably, a guide pipe is provided on one side of the corrosion-resistant isolation cavity near the top, and the other end of the guide pipe is fixedly inserted inside the main drainage cavity.

[0015] By adopting the above technical solution, the anti-corrosion isolation chamber is connected to the main drainage chamber through a guide pipe. The guide pipe is set near the top of the anti-corrosion isolation chamber to prevent overflow of the anti-corrosion isolation chamber.

[0016] Preferably, the guide tube is provided with an installation plate inside, a spring is provided on one side of the installation plate, an annular ring is provided inside the guide tube, and a plug is provided at the other end of the spring, the plug being adapted to the annular ring.

[0017] By adopting the above technical solution, the guide pipe is equipped with a spring, plug and annular ring cooperation structure, which can prevent water in the main drainage chamber from flowing back to the anti-corrosion isolation chamber, thus achieving the effect of preventing backflow.

[0018] Preferably, both the pretreatment chamber and the corrosion-resistant isolation chamber are provided with partitions at their bottoms, and both sets of partitions are provided with through holes on their surfaces.

[0019] By adopting the above technical solution, a partition with through holes is set at the bottom of the pretreatment chamber and the anti-corrosion isolation chamber. The partition can separate the internal space of each chamber, and the through holes ensure that the water flows through in an orderly manner, so that the water is fully treated before entering the next chamber, thereby improving the pertinence and effectiveness of each chamber's function.

[0020] Preferably, both the pretreatment chamber and the main drainage chamber are made of corrosion-resistant concrete, and a water outlet pipe is provided on one side of the main drainage chamber.

[0021] By adopting the above technical solution, the pretreatment chamber and the main drainage chamber are made of corrosion-resistant concrete material. With the addition of the outlet pipe, the corrosion resistance of these two chambers is enhanced, enabling them to resist long-term erosion by the flowing water.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] This corrosion-resistant composite compartmentalized municipal drainage structure forms a compartmentalized structure by fixing the pretreatment chamber, corrosion-resistant isolation chamber, and main drainage chamber with studs. This achieves functional zoning of the drainage process, making the pretreatment, corrosion-resistant isolation, and main drainage functions independent yet coordinated. It avoids the problem of insufficient corrosion resistance caused by the mixed functions of traditional single chambers, and improves the overall corrosion resistance and operational stability of the drainage structure. In addition, each chamber is installed independently, which facilitates individual maintenance and replacement. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 This application will be described in further detail below.

[0032] Example 1: A corrosion-resistant composite compartmentalized municipal drainage structure, referring to... Figure 1 The system includes a pretreatment chamber 2, an anti-corrosion isolation chamber 3, and a main drainage chamber 4. The anti-corrosion isolation chamber 3 is fixedly installed at the bottom of the pretreatment chamber 2 by studs, and the main drainage chamber 4 is fixedly installed at the bottom of the anti-corrosion isolation chamber 3 by studs. A cover plate 1 is installed on the top of the pretreatment chamber 2 by studs, and two sets of water inlet pipes 5 are installed on the top of the cover plate 1. By fixing the pretreatment chamber 2, the anti-corrosion isolation chamber 3, and the main drainage chamber 4 with studs to form a compartmentalized structure, the functional zoning of the drainage process is realized. The pretreatment, anti-corrosion isolation, and main drainage functions are independent yet coordinated, avoiding the problem of insufficient corrosion resistance caused by the mixed functions of traditional single chambers. The overall corrosion resistance and operational stability of the drainage structure are improved, and the independent installation of each chamber facilitates individual maintenance and replacement.

[0033] Example 2: A corrosion-resistant composite compartmentalized municipal drainage structure, referring to... Figure 2 , Figure 3 and Figure 4Both sides of the inner wall of the pretreatment chamber 2 are provided with guide plates 201, and both sides of the inner wall of the pretreatment chamber 2 are provided with grooves 202. The same filter assembly 6 is provided in both sets of grooves 202. The guide plates 201 and the filter assembly 6 in the grooves 202 are provided in the inner wall of the pretreatment chamber 2. The guide plates 201 can reduce the impact of water flow turbulence on the chamber. The filter assembly 6 can perform preliminary filtration of the incoming water flow, intercept impurities, reduce the wear of the subsequent anti-corrosion isolation chamber 3 and main drainage chamber 4 caused by impurities, and ensure the service life of the overall structure. The filter assembly 6 includes two connecting blocks 603 and two mounting blocks 607. The two connecting blocks 603 are slidably connected in the two grooves 202 respectively. A lead screw 605 is mounted on the bottom of component 3 via a pivot. The end of the lead screw 605 is mounted on a mounting block 607 via the pivot. Two mounting blocks 607 are slidably connected in two grooves 202. A threaded block 606 is threadedly connected to the surface of the lead screw 605. A slide rod 609 is mounted on the bottom of another connecting block 603. A slider 608 is slidably connected to the surface of the slide rod 609. A grid plate 601 is positioned between the slider 608 and the threaded block 606. A filter plate 602 is positioned between the two mounting blocks 607. A knob 604 is mounted on the top of one connecting block 603. The knob 604 is fixedly connected to the end of the lead screw 605 via a pivot. The filter assembly 6 uses a lead screw 605, a threaded block 606, and... The sliding rod 609 and slider 608, in conjunction with the structure of the grille 601 and filter plate 602, allow the position of the grille 601 to be adjusted by rotating the screw 605 via the knob 604. This facilitates adjustment of the filter gap according to the impurity content of the water flow, improving filtration adaptability. Simultaneously, the connecting block 603 and the mounting block 607 are slidably connected within the groove 202, making it easy to disassemble, clean, or replace the grille 601 and filter plate 602, reducing maintenance difficulty and ensuring long-term stable filtration performance. The corrosion-resistant isolation chamber 3, from the inside out, is equipped with a polytetrafluoroethylene plate 303, a fiberglass mesh 302, a main frame 301, and the polytetrafluoroethylene plate 303 and fiberglass mesh 302 are connected to each other. Epoxy resin adhesive is installed between the main frame 301. Three sets of arc-shaped platforms 304 are installed inside the corrosion-resistant isolation cavity 3. The corrosion-resistant isolation cavity 3 adopts a layered structure of polytetrafluoroethylene plate 303, fiberglass mesh cloth 302 and main frame 301, and the layers are bonded by epoxy resin adhesive. The polytetrafluoroethylene plate 303 is in direct contact with the corrosive medium and blocks the corrosion path with its corrosion resistance. The fiberglass mesh cloth 302 enhances the crack resistance of the interlayer connection, offsets the deformation stress of different materials, and avoids interlayer cracking and leakage. The main frame 301 provides structural support and, together with the internal arc-shaped platforms 304, guides the water flow to flow smoothly and reduces turbulent impact, further improving the corrosion resistance, durability and structural stability of the corrosion-resistant isolation cavity 3.

[0034] Example 3: A corrosion-resistant composite compartmentalized municipal drainage structure, referring to... Figure 2 , Figure 5 and Figure 6 A guide pipe 8 is installed near the top of one side of the corrosion-resistant isolation chamber 3. The other end of the guide pipe 8 is fixedly inserted into the main drainage chamber 4, connecting the corrosion-resistant isolation chamber 3 and the main drainage chamber 4. The guide pipe 8 is positioned near the top of the corrosion-resistant isolation chamber 3 to prevent overflow. An installation plate 10 is installed inside the guide pipe 8, with a spring 11 on one side. An annular ring 12 is installed inside the guide pipe 8, and a plug 13 is installed at the other end of the spring 11. The plug 13 fits into the annular ring 12. This mating structure of the spring 11, plug 13, and annular ring 12 inside the guide pipe 8 prevents water in the main drainage chamber 4 from flowing back into the corrosion-resistant isolation chamber 3, achieving [the desired effect]. To prevent backflow, both the pretreatment chamber 2 and the corrosion-resistant isolation chamber 3 are equipped with baffles 7 at their bottoms. Both baffles 7 have through holes on their surfaces. The baffles 7 can separate the internal spaces of each chamber, and the through holes ensure that the water flows through in an orderly manner, allowing the water to be fully treated before entering the next chamber, thus improving the targetedness and effectiveness of each chamber's function. Both the pretreatment chamber 2 and the main drainage chamber 4 are made of corrosion-resistant concrete. A water outlet pipe 9 is installed on one side of the main drainage chamber 4. The use of corrosion-resistant concrete in the pretreatment chamber 2 and the main drainage chamber 4, along with the installation of the water outlet pipe 9, enhances the corrosion resistance of these two chambers, enabling them to withstand long-term erosion by the flowing water.

[0035] The implementation principle of this application embodiment is as follows: During use, water flows into the pretreatment chamber 2 through the two sets of inlet pipes 5 at the top of the cover plate 1. The guide plate 201 on the inner wall of the pretreatment chamber 2 guides the water flow along a preset path, reducing the impact of water flow turbulence on the chamber. The water then flows through the filter assembly 6 in the groove 202, first intercepting larger particles of impurities through the grid plate 601, and then filtering fine impurities through the filter plate 602. If it is necessary to adjust the filter gap, the knob 604 on the top of the connecting block 603 can be rotated, which drives the threaded block 606 to move through the screw 605. In conjunction with the slider 608 on the slide rod 609, the position of the grid plate 601 can be adjusted. The pretreated water flows into the anti-corrosion isolation chamber 3 through the through hole of the bottom partition plate 7 of the pretreatment chamber 2. The three sets of arc-shaped platforms 304 in the anti-corrosion isolation chamber 3 guide the water flow smoothly, reducing the impact of turbulence. The layered structure of the anti-corrosion isolation chamber 3 plays a role. The inner polytetrafluoroethylene plate 303 directly contacts the water flow and blocks corrosion due to its corrosion resistance. The process involves using fiberglass mesh 302 in conjunction with epoxy resin to enhance the crack resistance of interlayer connections, offset the deformation stress of different materials, and prevent interlayer cracking and leakage. The main frame 301 provides stable support and ensures the structural strength of the corrosion-resistant isolation chamber 3. After the water is treated in the corrosion-resistant isolation chamber 3, when the water level in the chamber reaches a certain height, the water flows through the guide pipe 8 near the top to the main drainage chamber 4. In the guide pipe 8, the water pressure pushes the plug 13 to compress the spring 11, causing the plug 13 to separate from the annular ring 12, allowing the water to flow smoothly. If the water level in the main drainage chamber 4 flows backward, the spring 11 resets, causing the plug 13 to fit against the annular ring 12, preventing backflow of water. The water entering the main drainage chamber 4 is finally discharged through the outlet pipe 9 on one side. Throughout the process, the corrosion-resistant concrete material of the pretreatment chamber 2 and the main drainage chamber 4 enhances their own corrosion resistance. The targeted protection of the corrosion-resistant isolation chamber 3 and the coordinated cooperation of each chamber achieve efficient treatment and discharge of water.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be included within the scope of protection of this application.
