Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline connection technology, and in particular to an anti-clogging rainwater and sewage diversion pipeline connection structure. Background Technology
[0002] In modern urban construction and environmental protection, stormwater and sewage separation systems play a crucial role. These systems separate and transport surface runoff from rainfall with wastewater generated by residential and industrial processes through independent networks of rainwater and sewage pipes. This is significant for improving the treatment efficiency of sewage treatment plants, preventing river pollution, and mitigating urban flooding.
[0003] Effective separation of rainwater and sewage relies on the stable and reliable operation of the pipeline system. In traditional pipeline construction, pipe sections are typically connected using methods such as flange connections, socket bonding, or heat fusion. These connection methods often require a high level of technical expertise from the construction environment and operators, and the process is relatively cumbersome. Furthermore, over long-term use, the joints may experience decreased sealing performance or even leakage due to factors such as material aging or foundation settlement, thus undermining the original purpose of rainwater and sewage separation.
[0004] An even more serious challenge comes from pipe blockage. Rainwater pipes inevitably accumulate sediment, leaves, and other debris, while sewage pipes often contain various types of household waste. These impurities easily accumulate inside the pipes, especially at joints and bends, under the influence of water flow, gradually forming blockages. Once a pipe becomes blocked, traditional methods of handling it are usually very complex, often requiring large-scale dredging equipment, and sometimes even excavation and severing of the affected pipe section. This not only results in high maintenance costs but also severely impacts normal drainage function and the surrounding environment. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a clog-resistant rainwater and sewage diversion pipe connection structure, which aims to improve the problems of inconvenient connection and sealing of existing rainwater and sewage diversion pipes and the difficulty in cleaning after the pipes are clogged by impurities.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A clog-resistant rainwater and sewage diversion pipe connection structure includes: a diversion pipe, a rainwater pipe, a drainage pipe, a sewage pipe, and a discharge pipe; as well as a connecting component for connecting the pipes and an anti-clogging component for preventing clogging;
[0008] The inside of the diversion pipe is provided with a partition plate extending along its length, which divides the inner cavity of the diversion pipe into mutually isolated rainwater channels and sewage channels;
[0009] The rainwater pipe and drainage pipe are respectively connected to both ends of the rainwater channel, and the sewage pipe and wastewater pipe are respectively connected to both ends of the sewage channel, thus forming two completely independent transport paths. The connecting assembly detachably connects the rainwater pipe and sewage pipe to the diversion pipe, and the anti-clogging component is installed inside the rainwater pipe and sewage pipe in a retractable manner.
[0010] Preferably, the connecting assembly includes a housing fixed to the inlet end of the diverter pipe, a sliding ring is slidably disposed inside the housing, and a toothed ring is also disposed inside the housing that is radially contracted by the axial displacement of the sliding ring.
[0011] Preferably, an annular sealing groove is formed on the inner wall of the outer casing; the connecting assembly further includes a sealing ring, which is fitted around the outer periphery of the rainwater pipe or sewage pipe and embedded in the sealing groove.
[0012] Preferably, the sliding ring is installed in a position that allows it to be abutted and pushed by the end of the rainwater pipe or sewage pipe inserted into the housing.
[0013] Preferably, the anti-blocking component includes an interception net; a sealing block is fixed on the outer wall of both the rainwater pipe and the sewage pipe, and a sliding groove is provided on the sealing block; a connecting block is fixed at the top of the interception net, and a slider that slides in cooperation with the sliding groove is provided on the connecting block.
[0014] Preferably, the connecting block and the sealing block can be inserted and fitted together to form a seal.
[0015] Preferably, the anti-blocking component further includes a handle fixed to the connecting block.
[0016] Preferably, the mesh surface of the interception net is perpendicular to the axial direction of the pipeline in which it is located.
[0017] Preferably, the ends of the drain pipe and the sewage pipe are further reinforced by flange fastening.
[0018] This utility model has the following beneficial effects:
[0019] 1. This utility model solves the problems of complex pipe connection operation, unreliable fixing and poor sealing in the prior art by setting a self-locking connection assembly composed of a shell, a sliding ring and a toothed ring. The structure uses the sliding ring to push and squeeze the toothed ring to generate radial locking when the pipe is inserted, thus achieving the technical effect of rapid installation, stable connection and reliable sealing.
[0020] 2. This utility model solves the problem in the prior art that the pipe must be disassembled for cleaning and maintenance after the pipe becomes blocked by setting an anti-blocking component with a slider and a groove that can be pulled out from the outside of the pipe. This makes the process cumbersome and time-consuming. It achieves the technical effect of quickly cleaning and maintaining the interception net without interrupting the main pipeline, thus improving practicality and convenience.
[0021] 3. This utility model solves the problem that existing diversion structures may cause rainwater and sewage to mix and the diversion may not be thorough by setting an isolation plate inside the diversion pipe, thus achieving a stable and reliable rainwater and sewage diversion technology effect and avoiding cross-contamination of water bodies.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Reference Figures 1-5 This utility model provides an embodiment of a rainwater and sewage diversion pipe connection structure, including a diversion pipe 1, a rainwater pipe 2, a sewage pipe 3, a connecting component 4, a drain pipe 5, a sewage discharge pipe 6, and an anti-clogging component 8. The diversion pipe 1 is provided with an isolation plate extending along its length, which divides the inner cavity of the diversion pipe 1 into mutually isolated rainwater channels and sewage channels. The rainwater pipe 2 is connected to the inlet end of the rainwater channel, and the drain pipe 5 is connected to the outlet end of the rainwater channel, thus forming an independent rainwater transport path. At the same time, the sewage pipe 3 is connected to the inlet end of the sewage channel, and the sewage discharge pipe 6 is connected to the outlet end of the sewage channel, thus forming a sewage transport path that is completely physically isolated from the rainwater transport path. The connecting component 4 is used to detachably connect the rainwater pipe 2 and the sewage pipe 3 to the corresponding rainwater channel inlet and sewage channel inlet of the diversion pipe 1, respectively. The anti-clogging component 8 is removably installed inside the rainwater pipe 2 and the sewage pipe 3.
[0031] The connecting assembly 4 includes a housing 401, which is fixed to the rainwater inlet or sewage inlet of the diversion pipe 1. An annular sealing groove 403 is formed on the inner wall of the housing 401. A sliding ring 405 is slidably disposed inside the housing 401, capable of moving along the axis of the rainwater pipe 2 or sewage pipe 3. A toothed ring 404 is also provided inside the housing 401, which can radially contract under the pressure of the axial displacement of the sliding ring 405. Simultaneously, the connecting assembly 4 also includes a sealing ring 402, which is fitted onto the rainwater pipe 2 or sewage pipe 3. In the assembled state, the outer periphery of the insertion end of the water pipe 3, the rainwater pipe 2 or sewage pipe 3 together with its external sealing ring 402 are inserted into the outer shell 401. The sealing ring 402 is then embedded in the sealing groove 403 to form the first seal. The end of the pipe abuts against and pushes the sliding ring 405 to slide inward. The movement of the sliding ring 405 compresses the toothed ring 404, thereby causing the inner teeth of the toothed ring 404 to tightly bite against the outer wall of the rainwater pipe 2 or sewage pipe 3, thereby achieving rapid locking and fixing of the pipe. This combination connection structure of the sealing ring and the toothed ring ensures the sealing and structural stability of the pipe connection.
[0032] To address pipe blockage issues and facilitate maintenance, the anti-blocking component 8 employs a retractable modular design. The anti-blocking component 8 includes an interception net 802, the mesh surface of which is perpendicular to the axis of the pipe it is located in. Sealing blocks 801 are fixed to the outer walls of both the rainwater pipe 2 and the sewage pipe 3. Each sealing block 801 has a groove 805. A connecting block 803 is fixed to the top of the interception net 802. The connecting block 803 has a slider 804 that slides along the groove 805, allowing the entire interception net 802 to be easily inserted into or removed from the pipe sidewall along the direction of the groove 805. The connecting block 803 and the sealing block 801 can be inserted and fitted together. When the interception net is blocked... When the interceptor 802 is fully pushed into the working position of the pipe, the connecting block 803 fits tightly against the sealing block 801, thereby forming an effective seal on the pull-out port and preventing water leakage from there. To improve the ease of operation, the anti-blocking component 8 also includes a handle 806 fixed on the connecting block 803. Users can easily pull the interceptor 802 by holding the handle 806. To further enhance the reliability of the pipe end connection, the ends of the drain pipe 5 and the sewage pipe 6 are also reinforced by a flange buckle 7. The flange buckle 7 is a ring-shaped snap-fit structure that can be fastened at the pipe interface, providing additional leak-proof protection and mechanical strength.
[0033] Working principle: When installing the pipe, the operator first puts the sealing ring 402 on the outer wall of the end of the rainwater pipe 2 or sewage pipe 3, and then aligns the pipe end with the outer shell 401 of the connecting component 4 and inserts it. During the insertion process, the sealing ring 402 will slide into the sealing groove 403 in the outer shell 401 to form a seal. At the same time, the end of the pipe will push the sliding ring 405 to slide inward. The sliding ring 405 will then squeeze the toothed ring 404, causing the toothed ring 404 to contract radially and tightly lock into the outer wall of the pipe, completing a quick and firm installation.
[0034] During normal system operation, rainwater enters through rainwater pipe 2, flows through the rainwater channel within the diversion pipe 1, and is finally discharged through drain pipe 5. Sewage enters through sewage pipe 3, flows through the sewage channel isolated from it within the diversion pipe 1, and is finally discharged through sewage pipe 6, achieving complete separation of rainwater and sewage. In this process, the water flow must first pass through the interception net 802 of the anti-blocking component 8, where solid impurities in the water are intercepted, effectively preventing blockage of downstream pipes.
[0035] When maintenance and cleaning are required, the maintenance personnel first shut off the upstream water source, then hold the handle 806 on the anti-blocking component 8 and pull the connecting block 803 together with the intercepting net 802 from the sealing block 801 along the direction of the slide 805. After cleaning the impurities on the intercepting net 802, push it back to its original position along the slide 805 until the connecting block 803 and the sealing block 801 are sealed again. The entire maintenance process does not require disassembling the main pipeline, making the operation extremely convenient.
