Abstract
Description
Technical Field
[0001] This application relates to the field of stormwater pipes, and in particular to a cross-street stormwater pipe interface structure. Background Technology
[0002] With the improvement of urbanization, municipal stormwater pipes in urban areas have played a significant role in preventing urban flooding. Stormwater pipes are specially designed pipe systems to transport intercepted rainwater in towns and cities, guiding rainwater from rooftops to ground or underground drainage systems.
[0003] During the rainy season, street drainage systems play a crucial role in reducing rainwater accumulation and minimizing its impact on traffic and pedestrians. The airtightness of the joints between drainage pipes is essential for ensuring rainwater can smoothly enter the drainage system.
[0004] Currently, rainwater pipes are sealed using a sealing ring, which is located at the base of the spigot end, specifically at the end of the female connector. This location experiences the greatest deformation under stress. Uneven stress during installation can lead to leaks. Summary of the Invention
[0005] To enhance the sealing performance of rainwater pipe interfaces and reduce the risk of leakage at the interfaces, this application provides a structure for a rainwater pipe interface across a street.
[0006] The technical solution for the cross-street storm drain interface structure provided in this application is as follows:
[0007] A cross-street storm drain pipe interface structure includes:
[0008] The interface body can be fitted onto the end of the rainwater pipe;
[0009] A connecting component is disposed on the inner wall of the interface body and connected to the rainwater pipe. The connecting component includes multiple protruding rings disposed inside the interface body and threads formed on the side of the protruding rings away from the interface body.
[0010] A sealing ring is disposed on the side of the thread away from the interface body. When the sealing ring contacts the rainwater pipe, the connecting assembly is interference-fitted with the sealing ring.
[0011] By adopting the above technical solution and designing the connecting components and sealing rings, efficient connection and tight sealing between the rainwater pipe and the interface are achieved. The combination of multiple convex rings and threads not only enhances the stability of the connection but also ensures a seamless fit between the interface and the rainwater pipe, effectively preventing rainwater leakage. The easy disassembly of the connecting components and sealing rings allows maintenance personnel to easily inspect and replace them, greatly reducing maintenance costs and time. Thus, the connecting components and sealing rings enhance the sealing performance of the rainwater pipe interface, thereby reducing the risk of leakage at the interface.
[0012] Optionally, a plurality of the protruding rings are spaced apart along the length of the interface body, and a space is provided between the protruding rings for the slag generated during twisting to enter.
[0013] By employing the above technical solution, some slag or debris is often generated during the tightening process. The space between these protruding rings can effectively contain this slag, preventing it from entering the interface and thus keeping the interface clean and unobstructed. The presence of slag can increase friction during tightening, leading to accelerated interface wear. Containing slag through the space between the protruding rings reduces this unnecessary friction and extends the service life of the interface. Furthermore, this spaced arrangement can effectively distribute stress, improving the interface's resistance to pressure and impact.
[0014] Optionally, the adjacent convex rings have different lengths, with the length of the convex rings set to 10mm-12mm.
[0015] By adopting the above technical solution, convex rings of different lengths can better adapt to interfaces or connecting components of different sizes and shapes, improving the product's versatility and flexibility. Different convex ring lengths allow for a tighter fit at the interface, thereby enhancing sealing performance and preventing gas or liquid leakage. This further enhances the sealing of the rainwater pipe interface, reducing the risk of leakage. The difference in length between adjacent convex rings can also increase the structural stability of the interface to a certain extent, making it more robust and reliable, and able to withstand greater pressure and impact.
[0016] Optionally, a friction block that fits into the rainwater pipe is provided on the inner side of the sealing ring. The cross-section of the friction block is set as a right-angled triangle, and the distance from the inclined surface of the friction block to the sealing ring gradually decreases from the pipe opening closer to the rainwater pipe to the pipe opening farther away from the rainwater pipe.
[0017] By adopting the above technical solution, the friction block increases the contact area and friction between the sealing ring and the rainwater pipe, resulting in a tighter and more reliable seal. The right-angled triangular cross-sectional shape ensures a good sealing effect under different pressures. When the rainwater pipe is squeezed or expanded, the friction block can flexibly adjust its position to maintain a tight fit with the pipe. Furthermore, the combination of the friction block and the sealing ring enhances the stability of the entire interface structure.
[0018] Optionally, the sealing ring is configured as an integrally formed annular sealing ring with uniform hardness throughout.
[0019] By adopting the above technical solution, the sealing ring is integrally molded, ensuring the durability and stability of the interface structure. Even under harsh weather conditions, the sealing ring maintains stable performance, effectively preventing malfunctions such as rainwater leakage caused by interface problems. Furthermore, the sealing ring has a uniform hardness throughout, providing not only excellent sealing performance but also greater environmental friendliness.
[0020] Optionally, the end of the interface body is provided with water-stop teeth, and the number of water-stop teeth is at least two, and the cross-section of the water-stop teeth is set as continuous sawtooth shape.
[0021] By adopting the above technical solution, the serrated water-stop teeth significantly enhance the sealing performance of the interface, effectively preventing liquid or gas leakage and ensuring the safety and reliability of the connection. The water-stop teeth also add a self-locking function, making the interface less prone to separation under external force, further enhancing the stability of the connection. Furthermore, the serrated water-stop teeth improve the wear resistance and durability of the interface.
[0022] Optionally, the outer side of the interface body is inclined, and the distance from the inclined surface of the outer side of the interface body to the central axis of the interface body gradually increases from the pipe opening near the rainwater pipe to the pipe opening away from the rainwater pipe.
[0023] By adopting the above technical solution, the inclined outer design can act as a guide, allowing rainwater to flow smoothly down the slope when passing through the interface, reducing the risk of stagnation and blockage. The gradually increasing distance helps to form a smoother drainage channel, facilitating interface installation and thus improving installation efficiency. Furthermore, when subjected to external forces, the inclined surface can better disperse stress, reducing the possibility of interface damage.
[0024] Optionally, at least two convex rings are provided on the outer side of the interface body, and the convex rings are spaced apart.
[0025] By adopting the above technical solution, the convex ring design increases the external surface area of the interface body, thereby increasing the contact area with the surrounding structure. This helps to disperse stress, making the interface more stable under external forces and reducing the risk of interface damage. Furthermore, during installation, it increases the friction between the worker and the interface, making installation easier. During installation or connection, the convex ring serves as a clear physical reference point, helping operators to align and position the interface more quickly and accurately, thus improving installation efficiency.
[0026] In summary, this application includes at least one of the following beneficial technical effects:
[0027] 1. By incorporating an interface body, connecting components, sealing rings, raised rings, and threads, the design of the connecting components and sealing rings achieves efficient connection and tight sealing between the rainwater pipe and the interface. The combination of multiple raised rings and threads not only enhances the stability of the connection but also ensures a seamless fit between the interface and the rainwater pipe, effectively preventing rainwater leakage. The easy disassembly of the connecting components and sealing rings allows maintenance personnel to easily inspect and replace them, significantly reducing maintenance costs and time. Thus, the connecting components and sealing rings enhance the sealing performance of the rainwater pipe interface, thereby reducing the risk of leakage at the interface.
[0028] 2. By incorporating friction blocks, the contact area and friction between the sealing ring and the rainwater pipe are increased, resulting in a tighter and more reliable seal. The right-angled triangular cross-section ensures a good seal under varying pressures. When the rainwater pipe is compressed or expanded, the friction blocks can flexibly adjust their position to maintain a tight fit. Furthermore, the combination of the friction blocks and the sealing ring enhances the stability of the entire interface structure.
[0029] 3. By incorporating water-stop teeth, at least two teeth are included, with the cross-section of each tooth featuring a continuous serrated shape. The serrated water-stop teeth significantly enhance the sealing performance of the interface, effectively preventing liquid or gas leakage and ensuring a safe and reliable connection. The water-stop teeth also add a self-locking function, making the interface less prone to separation under external force, further enhancing the stability of the connection. Furthermore, the serrated water-stop teeth improve the wear resistance and durability of the interface. Attached Figure Description

[0034] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0035] This application discloses a structure for a street-crossing storm drain interface.
[0036] Reference Figure 1 , Figure 2 and Figure 3 A cross-street storm drain pipe interface structure includes an interface body 1 that can be fitted onto the end of the storm drain pipe, a connecting component 2 disposed on the inner wall of the interface body 1, and a sealing ring 3 disposed on the side of the connecting component 2 away from the interface body 1.
[0037] The connecting component 2 is connected to the rainwater pipe. The connecting component 2 includes multiple protruding rings 21 disposed inside the interface body 1 and threads 22 formed on the side of the protruding rings 21 away from the interface body 1. The sealing ring 3 is disposed on the side of the threads 22 away from the interface body 1. When the sealing ring 3 contacts the rainwater pipe, the connecting component 2 and the sealing ring 3 are interference-fitted.
[0038] The design of connecting component 2 and sealing ring 3 achieves efficient connection and tight sealing between the rainwater pipe and the interface. The combination of multiple convex rings 21 and threads 22 not only enhances the stability of the connection but also ensures a seamless fit between the interface and the rainwater pipe, effectively preventing rainwater leakage. The easy disassembly of connecting component 2 and sealing ring 3 allows maintenance personnel to easily inspect and replace them, greatly reducing maintenance costs and time. Therefore, connecting component 2 and sealing ring 3 enhance the sealing performance of the rainwater pipe interface, thereby reducing the risk of leakage at the interface.
[0039] Reference Figure 2 and Figure 3 Multiple protruding rings 21 are spaced apart along the length of the interface body 1, with spaces between the protruding rings 21 to allow debris generated during tightening to enter. During tightening, debris or fragments are often generated. The spaces between these protruding rings 21 effectively contain this debris, preventing it from entering the interface and thus keeping the interface clean and unobstructed. The presence of debris can increase friction during tightening, leading to accelerated interface wear. Containing debris through the spaces between the protruding rings 21 reduces this unnecessary friction, extending the service life of the interface. Furthermore, this spaced arrangement effectively disperses stress, improving the interface's resistance to pressure and impact.
[0040] The adjacent raised rings 21 have different lengths, ranging from 10mm to 12mm. Different lengths of raised rings 21 can better adapt to interfaces or connecting parts of different sizes and shapes, improving the product's versatility and flexibility. By using different lengths of raised rings 21, a tighter fit can be formed at the interface, thereby enhancing sealing performance and preventing gas or liquid leakage. This further enhances the sealing of the rainwater pipe interface, reducing the risk of leakage. The difference in length between adjacent raised rings 21 can also increase the structural stability of the interface to a certain extent, making it more robust and reliable, and able to withstand greater pressure and impact.
[0041] Reference Figure 2 and Figure 3 The inner side of the sealing ring 3 is provided with a friction block 4 that fits into the rainwater pipe. The cross-section of the friction block 4 is set as a right triangle. The distance from the inclined surface of the friction block 4 to the sealing ring 3 gradually decreases from the pipe opening near the rainwater pipe to the pipe opening away from the rainwater pipe.
[0042] The friction block 4 increases the contact area and friction between the sealing ring 3 and the rainwater pipe, resulting in a tighter and more reliable seal. The right-angled triangular cross-section ensures a good seal under varying pressures. When the rainwater pipe is compressed or expanded, the friction block 4 can flexibly adjust its position to maintain a tight fit. Furthermore, the combination of the friction block 4 and the sealing ring 3 enhances the stability of the entire interface structure.
[0043] The sealing ring 3 is a one-piece molded annular ring with uniform hardness throughout. This one-piece molding ensures the durability and stability of the interface structure. Even under harsh weather conditions, the sealing ring 3 maintains stable performance, effectively preventing malfunctions such as rainwater leakage caused by interface problems. Furthermore, the uniform hardness throughout the sealing ring 3 not only provides excellent sealing performance but is also more environmentally friendly.
[0044] Reference Figure 2 The interface body 1 has at least two water-stop teeth 5 at its end, with a continuous serrated cross-section. These serrated water-stop teeth 5 significantly enhance the sealing performance of the interface, effectively preventing liquid or gas leakage and ensuring a safe and reliable connection. The water-stop teeth 5 also add a self-locking function, making the interface less prone to separation under external force, further enhancing the stability of the connection. Furthermore, the serrated water-stop teeth 5 improve the wear resistance and durability of the interface.
[0045] The outer side of the interface body 1 is inclined, and the distance from the inclined surface of the outer side of the interface body 1 to the central axis of the interface body 1 gradually increases from the pipe opening closer to the rainwater pipe to the pipe opening farther away from the rainwater pipe. The inclined outer design can guide rainwater to flow smoothly down the inclined surface when it flows through the interface, reducing the risk of stagnation and blockage. The gradually increasing distance helps to form a smoother drainage channel, facilitating the installation of the interface and thus improving installation efficiency. Furthermore, when subjected to external forces, the inclined surface can better disperse stress, reducing the possibility of interface damage.
[0046] Reference Figure 1 The interface body 1 has at least two convex rings 6 spaced apart on its outer side. The design of the convex rings 6 increases the external surface area of the interface body 1, thereby increasing the contact area with surrounding structures, helping to disperse stress, making the interface more stable under external forces, and reducing the risk of interface damage. Furthermore, during installation, it increases the friction between the operator and the interface, making installation easier. During installation or connection, the convex rings 6 serve as clear physical reference points, helping operators to align and position the interface more quickly and accurately, thus improving installation efficiency.
[0047] The implementation principle of the cross-street storm drain pipe interface structure in this application embodiment is as follows: Through the design of the connecting component 2 and the sealing ring 3, efficient connection and tight sealing between the storm drain pipe and the interface are achieved. The combination of multiple convex rings 21 and threads 22 not only enhances the stability of the connection but also ensures a seamless fit between the interface and the storm drain pipe, effectively preventing rainwater leakage. The easy disassembly of the connecting component 2 and the sealing ring 3 allows maintenance personnel to easily inspect and replace them, greatly reducing maintenance costs and time. Thus, the connecting component 2 and the sealing ring 3 enhance the sealing performance of the storm drain pipe interface, thereby reducing the risk of leakage at the interface.
[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
