Description

Technical Field

[0001] This utility model relates to the technical field of rainwater drainage auxiliary equipment, and in particular to a siphon rainwater hopper connector and its siphon rainwater hopper. Background Technology

[0002] Siphonic rainwater hoppers are the core component of siphonic rainwater drainage systems. Their design principle is based on the siphon effect in fluid mechanics, enabling efficient and rapid drainage of rainwater from roofs. They are widely used on various large roofs, factories, train stations, supermarkets, airports, hotels, and other rooftops. When using siphonic rainwater hoppers, a stainless steel base needs to be connected to HDPE pipes (high-density polyethylene pipes). Therefore, we urgently need a siphonic rainwater hopper connector and the siphonic rainwater hopper itself.

[0003] Currently, the connection method between the stainless steel chassis and the HDPE pipe is as follows:

[0004] 1. Threaded connection: After the connection is made, glue is applied between the stainless steel base and the HDPE pipe. However, after a period of time, the glued area is easily damaged, which can lead to water leakage at the connection between the stainless steel base and the HDPE pipe.

[0005] 2. Flange connection: Flange connection is extremely unstable and can easily lead to loosening between the stainless steel base and the HDPE pipe. The unstable connection between the stainless steel base and the HDPE pipe can also cause water leakage at the connection point. Utility Model Content

[0006] To address the shortcomings of the existing production technology, the applicant provides a siphon-type rainwater hopper connector and its siphon-type rainwater hopper. By improving the connection method between the stainless steel chassis and the HDPE pipe, leakage at the connection point between the stainless steel chassis and the HDPE pipe is avoided. At the same time, the stability of the connection between the stainless steel chassis and the HDPE pipe is also improved.

[0007] The technical solution adopted in this utility model is as follows:

[0008] A siphon-type rainwater hopper connector includes: a stainless steel base, an HDPE pipe, and a limiting mechanism. The stainless steel base is a hollow structure, and the HDPE pipe is a hollow structure and is integrally injection molded with the stainless steel base. The limiting mechanism is installed between the stainless steel base and the HDPE pipe and is used to limit the axial movement between the stainless steel base and the HDPE pipe, as well as the circumferential rotation between the stainless steel base and the HDPE pipe.

[0009] Therefore, the integral injection molding connection method of the stainless steel chassis and HDPE pipe, compared with the existing threaded or flanged connections, is simpler in structure and easier to operate. The integral injection molding ensures a tighter connection between the stainless steel chassis and HDPE pipe, preventing leakage at the connection point. Furthermore, the integral injection molding simplifies the installation process of the entire siphon rainwater hopper connector, improving installation efficiency. In addition, the limiting mechanism restricts axial and circumferential movement between the stainless steel chassis and HDPE pipe, improving the stability of the connection and reducing the risk of damage to both components, thus lowering the overall maintenance rate of the siphon rainwater hopper connector. The stable connection further prevents leakage at the connection point.

[0010] As a further improvement to the above technical solution: the limiting mechanism includes: multiple first limiting parts and multiple second limiting parts, wherein the first limiting parts and the second limiting parts are all installed between the stainless steel chassis and the HDPE pipe; in the axial direction, the multiple first limiting parts are equally spaced, the multiple second limiting parts are equally spaced, and the first limiting parts and the second limiting parts are staggered; in the circumferential direction, the multiple first limiting parts are arranged in an equally spaced ring, and the multiple second limiting parts are arranged in an equally spaced ring. Thus, the multiple first limiting parts and the multiple second limiting parts generate constraint forces in both the axial and circumferential directions between the stainless steel chassis and the HDPE pipe, thereby restricting the axial movement and circumferential movement between the stainless steel chassis and the HDPE pipe.

[0011] As a further improvement to the above technical solution: the first limiting part includes: a first limiting block and a first limiting groove. The first limiting block is installed on the outer wall of the stainless steel chassis, and the first limiting groove is opened on the inner wall of the HDPE pipe. The first limiting block is adapted to the first limiting groove, and the first limiting block is inserted into the first limiting groove.

[0012] As a further improvement to the above technical solution: the second limiting part includes: a second limiting block and a second limiting groove. The second limiting block is installed on the inner wall of the HDPE pipe, and the second limiting groove is opened on the outer wall of the stainless steel chassis. The second limiting block is adapted to the second limiting groove, and the second limiting block is inserted into the second limiting groove.

[0013] As a further improvement to the above technical solution: the stainless steel chassis is inserted into the HDPE pipe and integrally injection molded with the HDPE pipe.

[0014] As a further improvement to the above technical solution: the HDPE pipe includes: a first connecting part, a second connecting part, and a third connecting part. The first connecting part and the second connecting part are located on the side closer to the stainless steel chassis, and the third connecting part is located on the side away from the stainless steel chassis. The first connecting part and the second connecting part are both connected to the third connecting part. An installation groove is formed between the first connecting part and the second connecting part. The limiting mechanism is installed between the first connecting part and the HDPE pipe.

[0015] As a further improvement to the above technical solution: an extension is provided on the side of the stainless steel chassis near the HDPE pipe.

[0016] As a further improvement to the above technical solution: the extension is inserted into the mounting groove, the outer wall of the extension abuts against the inner wall of the first connecting part, and the inner wall of the extension abuts against the outer wall of the second connecting part. Thus, by inserting the extension into the mounting groove, an axial support force is provided to the stainless steel chassis through the HDPE pipe, thereby further restricting the axial movement between the stainless steel chassis and the HDPE pipe, and improving the stability of the connection between the stainless steel chassis and the HDPE pipe.

[0017] As a further improvement to the above technical solution: the inner walls of the stainless steel chassis, the second connecting part, and the third connecting part are flush. Therefore, through this design where the inner walls of the stainless steel chassis, the second connecting part, and the third connecting part are flush, rainwater smoothly transitions between the stainless steel chassis and the HDPE pipe during the entire use of the siphon rainwater hopper, achieving more efficient and faster rainwater drainage.

[0018] A siphon-type rainwater hopper includes: a siphon-type rainwater hopper connector.

[0019] The beneficial effects of this utility model are as follows:

[0020] The integral injection molding connection method between the stainless steel base and HDPE pipe offers a simpler structure and easier operation compared to existing threaded or flanged connections. This integrated molding ensures a tighter connection between the stainless steel base and HDPE pipe, preventing leaks. Furthermore, the integrated molding simplifies the installation process of the siphon-type rainwater hopper connector, improving installation efficiency. In addition, the limiting mechanism restricts axial and circumferential movement between the stainless steel base and HDPE pipe, enhancing connection stability and reducing the risk of damage. This lowers the overall maintenance rate of the siphon-type rainwater hopper connector. The stable connection further prevents leaks at the joint.

[0021] This utility model also has the following advantages:

[0022] 1. This utility model uses multiple first limiting parts and multiple second limiting parts to generate constraint forces between the stainless steel chassis and the HDPE pipe in both the axial and circumferential directions. In this way, the axial movement between the stainless steel chassis and the HDPE pipe and the circumferential movement between the stainless steel chassis and the HDPE pipe can be restricted.

[0023] 2. This utility model inserts the extension into the mounting groove and provides an axial support force to the stainless steel chassis through the HDPE pipe. This further restricts the axial movement between the stainless steel chassis and the HDPE pipe, thereby improving the stability of the connection between the stainless steel chassis and the HDPE pipe.

[0024] 3. This utility model uses a design where the inner walls of the stainless steel chassis, the second connecting part, and the third connecting part are flush, so that rainwater can smoothly transition between the stainless steel chassis and the HDPE pipe during the entire use of the siphon rainwater hopper, thereby achieving more efficient and faster rainwater discharge.

[0038] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0039] like Figures 1 to 4As shown, a siphon-type rainwater hopper connector includes: a stainless steel base 1, an HDPE pipe 2, and a limiting mechanism 3. The stainless steel base 1 is a hollow structure, the HDPE pipe 2 is a hollow structure, and both are integrally injection molded with the stainless steel base 1. The limiting mechanism 3 is installed between the stainless steel base 1 and the HDPE pipe 2 and is used to limit the axial movement between the stainless steel base 1 and the HDPE pipe 2 as well as the circumferential rotation between the stainless steel base 1 and the HDPE pipe 2. Therefore, the integral injection molding connection method of the stainless steel base 1 and HDPE pipe 2, compared with the existing threaded or flanged connections, is simpler in structure and easier to operate. The integral injection molding connection method ensures a tighter connection between the stainless steel base 1 and HDPE pipe 2, preventing leakage at the connection point. Simultaneously, the integral injection molding of the stainless steel base 1 and HDPE pipe 2 simplifies the installation steps of the entire siphon rainwater hopper connector, improving the installation efficiency. Furthermore, the limiting mechanism 3 restricts the axial movement and circumferential rotation between the stainless steel base 1 and HDPE pipe 2, improving the stability of the connection and reducing the risk of damage to the stainless steel base 1 and HDPE pipe 2, thereby reducing the maintenance rate of the entire siphon rainwater hopper connector. The stable connection between the stainless steel base 1 and HDPE pipe 2 further prevents leakage at the connection point.

[0040] In other words, the stainless steel chassis 1 and HDPE pipe 2 are integrally injection molded, turning the two components into one. In contrast, existing technologies, whether using threaded or flanged connections, design the stainless steel chassis 1 and HDPE pipe 2 as a single component, which reduces the risk of leakage. Furthermore, from an installation perspective, by integrally injection molding the stainless steel chassis 1 and HDPE pipe 2 during manufacturing, only one component needs to be installed during installation. This simplifies the installation process of the entire siphon rainwater hopper connector and improves its installation efficiency.

[0041] It should be noted that the integral injection molding of the stainless steel chassis 1 and the HDPE pipe 2 means that molten HDPE is injected onto the outer and inner walls of the stainless steel chassis 1 through a specific mold to form the HDPE pipe 2. The injection molding method enhances the adhesion performance at the connection between the stainless steel chassis 1 and the HDPE pipe 2, thereby making the connection between the stainless steel chassis 1 and the HDPE pipe 2 tighter.

[0042] In this embodiment, the limiting mechanism 3 includes: a plurality of first limiting parts 4 and a plurality of second limiting parts 5, wherein the first limiting parts 4 and the second limiting parts 5 are both installed between the stainless steel chassis 1 and the HDPE pipe 2; in the axial direction, the plurality of first limiting parts 4 are equally spaced, the plurality of second limiting parts 5 are equally spaced, and the first limiting parts 4 and the second limiting parts 5 are staggered; in the circumferential direction, the plurality of first limiting parts 4 are arranged in an equally spaced ring, and the plurality of second limiting parts 5 are arranged in an equally spaced ring; the first limiting part 4 includes: a first limiting block 401 and a first limiting groove 402, the first limiting block 401... The first limiting groove 402 is formed on the inner wall of the HDPE pipe 2 and installed on the outer wall of the stainless steel chassis 1. The first limiting block 401 is adapted to the first limiting groove 402 and is inserted into the first limiting groove 402. The second limiting part 5 includes a second limiting block 501 and a second limiting groove 502. The second limiting block 501 is installed on the inner wall of the HDPE pipe 2 and the second limiting groove 502 is formed on the outer wall of the stainless steel chassis 1. The second limiting block 501 is adapted to the second limiting groove 502 and is inserted into the second limiting groove 502. Thus, through multiple first limiting parts 4 and multiple second limiting parts 5, the stainless steel chassis 1 and the HDPE pipe 2 are constrained in both the axial and circumferential directions. In this way, the axial movement and circumferential movement between the stainless steel chassis 1 and the HDPE pipe 2 can be restricted.

[0043] It should be noted that: a first limiting block 401 and a second limiting groove 502 are provided on the outer wall of the stainless steel chassis 1. During injection molding, the inner wall of the HDPE pipe 2 forms a depression (i.e., the first limiting groove 402) relative to the position of the first limiting block 401, and the inner wall of the HDPE pipe 2 forms a protrusion (i.e., the second limiting block 501) relative to the position of the second limiting groove 502.

[0044] In this embodiment, a stainless steel base 1 is inserted into an HDPE pipe 2 and integrally injection molded with the HDPE pipe 2. The HDPE pipe 2 includes a first connecting part 201, a second connecting part 202, and a third connecting part 203. The first connecting part 201 and the second connecting part 202 are located on the side closer to the stainless steel base 1, and the third connecting part 203 is located on the side away from the stainless steel base 1. The first connecting part 201 and the second connecting part 202 are both connected to the third connecting part 203. The first connecting part 201 and the second connecting part 202 are connected to each other. An installation groove 204 is formed between the connecting parts 202; a limiting mechanism 3 is installed between the first connecting part 201 and the HDPE pipe 2; an extension part 101 is provided on the side of the stainless steel chassis 1 near the HDPE pipe 2; the extension part 101 is inserted into the installation groove 204, the outer wall of the extension part 101 abuts against the inner wall of the first connecting part 201, and the inner wall of the extension part 101 abuts against the outer wall of the second connecting part 202; the inner walls of the stainless steel chassis 1, the second connecting part 202, and the third connecting part 203 are flush. Therefore, the extension 101 is inserted into the mounting groove 204, and the HDPE pipe 2 provides an axial support force to the stainless steel chassis 1. This further restricts the axial movement between the stainless steel chassis 1 and the HDPE pipe 2, thereby improving the stability of the connection between the stainless steel chassis 1 and the HDPE pipe 2. With the design that the inner walls of the stainless steel chassis 1, the second connecting part 202, and the third connecting part 203 are flush, rainwater smoothly transitions between the stainless steel chassis 1 and the HDPE pipe 2 during the entire use of the siphon rainwater hopper, so as to achieve more efficient and faster rainwater discharge.

[0045] It should be noted that: the inner walls of the stainless steel base 1, the second connecting part 202, and the third connecting part 203 being flush means that the inner diameter R1 of the stainless steel base 1 = the inner diameter R2 of the second connecting part 202 = the inner diameter R3 of the third connecting part 203.

[0046] A siphon-type rainwater hopper includes: a siphon-type rainwater hopper connector.

[0047] The rainwater drainage process of this utility model is as follows: First, the integrally injection-molded stainless steel chassis 1 and HDPE pipe 2 are installed at the location where drainage is required; then, the side of the stainless steel chassis 1 away from the HDPE pipe 2 is welded to the location where drainage is required by argon arc welding, and the side of the HDPE pipe 2 away from the stainless steel chassis 1 is installed at the drain outlet; finally, when drainage is required, the siphon rainwater hopper can achieve more efficient and faster drainage based on the siphon effect of fluid mechanics.

[0048] In summary, the integral injection molding connection method of the stainless steel base 1 and HDPE pipe 2 of this utility model, compared with the existing threaded or flanged connections, has a simpler structure and is easier to operate. The integral injection molding connection method ensures a tighter connection between the stainless steel base 1 and HDPE pipe 2, preventing leakage at the connection point. Furthermore, the integral injection molding of the stainless steel base 1 and HDPE pipe 2 simplifies the installation steps of the entire siphon rainwater hopper connector, improving its installation efficiency. In addition, the limiting mechanism 3 restricts the axial movement and circumferential rotation between the stainless steel base 1 and HDPE pipe 2, improving the stability of the connection and reducing the risk of damage to the stainless steel base 1 and HDPE pipe 2, thereby reducing the maintenance rate of the entire siphon rainwater hopper connector. The stable connection between the stainless steel base 1 and HDPE pipe 2 further prevents leakage at the connection point.
