[0028] Example:
[0029] Figure 1It is a steel-plastic connected siphon rainwater hopper, including the hopper body (not shown), and also including an intermediate steel pipe 2 and an outer pipe 3. The intermediate steel pipe 2 includes a fitting 21, a flange 25, and a reinforcing rib assembly. The flange 25 is fixed to one end of the fitting 21 for connecting to the hopper body of the siphon rainwater hopper. The reinforcing rib assembly is fixed to the outer wall of the fitting 21. The outer pipe 3 is connected to the outside of the reinforcing rib assembly.
[0030] Figure 2 This is a schematic diagram of the middle steel pipe. Figure 3 yes Figure 2 A cross-sectional schematic diagram. Figure 4 yes Figure 2 Cross-sectional view Figure 5 yes Figure 4 Enlarged schematic diagram of part D in the middle.
[0031] like Figures 2-5 As shown, the reinforcing rib group includes multiple inner axial reinforcing ribs 22, multiple circumferential reinforcing ribs 23, and multiple outer axial reinforcing ribs 24. The pipe fitting 21 is disposed outside the inner pipe 1. The inner axial reinforcing ribs 22 are fixed to the outer wall of the pipe fitting 21. The circumferential reinforcing ribs 23 are fixed to the outer wall of the inner axial reinforcing ribs 22. The outer axial reinforcing ribs 24 are fixed to the outer wall of the circumferential reinforcing ribs 23. The outer pipe 3 is fixed outside the outer axial reinforcing ribs 24.
[0032] like Figure 2 As shown, the inner axial reinforcing ribs 22 are evenly distributed around the circumference, and the outer axial reinforcing ribs 24 are evenly distributed around the circumference. The inner axial reinforcing ribs 22 and the outer axial reinforcing ribs 24 are staggered.
[0033] The inner axial stiffener 22 and the outer axial stiffener 24 serve as two layers of stiffeners, which can improve strength and are staggered to further improve the strength and toughness of each position, forming an inner and outer structure that can improve the strength of both the inner and outer parts.
[0034] like Figure 3 As shown, both the inner axial reinforcing rib 22 and the outer axial reinforcing rib 24 are rectangular strip structures. The rectangular strip structure is easier to manufacture and weld.
[0035] like Figure 2 As shown, the circumferential reinforcing rib 23 includes a plurality of intermediate reinforcing ribs, the intermediate reinforcing ribs include a plurality of arc-shaped ribs 230, the plurality of arc-shaped ribs 230 are spaced apart from each other and evenly distributed around the circumference, and at least three inner layer axial reinforcing ribs 22 are fixedly connected to the inner wall surface of one arc-shaped rib 230.
[0036] In this embodiment, one of the intermediate reinforcing ribs includes four arc-shaped ribs 230, which are evenly distributed around the circumference. The number of inner axial reinforcing ribs 22 is 12, and the number of outer axial reinforcing ribs 24 is 12. One arc-shaped rib 230 connects three inner axial reinforcing ribs 22 and two outer axial reinforcing ribs 24.
[0037] Each of the arc-shaped ribs 230 in the same group is fixedly connected to a different inner axial reinforcing rib 22, which improves the tensile and compressive strength between the inner axial reinforcing ribs 22, and also utilizes the outer axial reinforcing rib 24 of the outer layer.
[0038] like Figure 2 As shown, the arc-shaped ribs 230 in adjacent groups are spaced at a certain angle. For example, ribs 2301 and ribs 2302 in adjacent groups are spaced at an angle on the circumference. In this embodiment, the interval is 30°, which is exactly the position of an inner axial reinforcing rib 22. Three groups form a cycle, so that the same inner axial reinforcing rib 22 has different tensile forces, resulting in better compressive strength.
[0039] The circumferential reinforcing rib 23 also includes a first annular reinforcing rib 231 and a second annular reinforcing rib 232 located on the outermost side. Both of these ribs are annular rings connected end to end, so that both ends of the inner axial reinforcing rib 22 and the outer axial reinforcing rib 24 have mounting points, which facilitates connection with the outer tube 3 and the fitting 21 and improves strength.
[0040] Figure 6 This is a schematic diagram of the outer tube. The inner wall of the outer tube 3 has multiple long grooves 31, and the outer axial reinforcing ribs 24 are fixed in the long grooves 31. The end of the outer tube 3 is also provided with an inwardly facing protruding ring 32, and the outer end face of the protruding ring 32 can be heat-fused to the drainage pipe.
[0041] It also includes an inner tube 1, with the fitting 21 disposed outside the inner tube 1. This invention also includes an inner tube, which strengthens the structure and prevents rainwater from causing the intermediate steel pipe 2 to rust.
[0042] The outer tube 3 and the inner tube 1 are both plastic tubes, while the middle steel tube 2 is made of steel. The fitting 21, multiple inner axial reinforcing ribs 22, multiple circumferential reinforcing ribs 23, and multiple outer axial reinforcing ribs 24 are welded together for better strength. The inner tube 1 and the fitting 21 can be connected by interference fit or common methods such as winding and wrapping composite.
[0043] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
