[0007] Furthermore, both ends of the second square tube are sealedly connected to the first square tube and the second square tube respectively through flanges.

[0008] Through the above arrangement, there is good sealing between the second square tube and the first square tube, and between the second square tube and the third square tube, and water leakage is not easy.

[0009] Furthermore, a first ear plate is fixedly connected to the inner wall of the upper side of the second square tube, a second ear plate is fixedly connected to the upper end of the baffle, and the first ear plate is rotatably connected to the second ear plate via a rotating shaft.

[0022] The technical solution of the present invention will be further specifically described below with reference to embodiments and in conjunction with the accompanying drawings.

[0023] like Figures 1 to 4As shown, a vertical pipe structure of a roof rainwater system includes a vertical pipe body 3, a filtering mechanism 4 and a branch pipe 5. The upper end of the vertical pipe body 3 is installed on the roof and is equipped with the filtering mechanism 4. The branch pipe 5 includes a first square pipe 51, a second square pipe 52 and a third square pipe 53. One end of the first square pipe 51 is fixedly connected to the vertical pipe body 3 at an angle downward, and the second square pipe 52 is coaxially and detachably connected between the first square pipe 51 and the third square pipe 53. The end of the third square pipe 53 away from the second square pipe 52 is connected to the floor. The branch pipe 5 also includes a baffle 54 whose upper end is hinged to the upper inner wall of the second square pipe 52. The baffle 54 is free to droop under the action of gravity to prevent odor in the vertical pipe body 3 from being discharged to the floor.

[0024] Through the above arrangement, first, the baffle 54 can prevent odor from being discharged to the floor; second, the second square tube 52 can be detachably connected between the first square tube 51 and the third square tube 53, so as to facilitate the maintenance or replacement of the baffle 54; third, the filtering mechanism 4 can prevent foreign matter on the roof from entering the riser body 3 and clogging the riser body 3.

[0025] The riser main body 3 of the present application is basically a vertically arranged circular tube, the upper end of which is installed on the roof to receive rainwater from the roof. The filtering mechanism 4 can adopt an existing filter structure to prevent foreign matter from mixing with rainwater into the riser main body 3. The first square tube 51, the second square tube 52 and the third tube 53 are basically coaxially arranged. The lower end of the first square tube 51 is welded to the riser main body 3. The domestic water of the floor passes through the third tube 53, the second square tube 52, the first square tube 51 and the riser main body 3 to be discharged to the ground. When the domestic water passes through the second square tube 52, the domestic water pushes open the baffle 54 and flows toward the riser main body 3. After the domestic water flows through the second square tube 52, the baffle 54 is opened. 4 hangs down freely under the action of gravity to prevent the odor in the riser body 3 from being discharged to the floor through the second riser; the baffle 54 of the present application is rectangular. When the baffle 54 hangs down freely, the gap between the edge of the baffle 54 and the side wall of the second square tube 52 is less than 5 mm; after long-term use, the rotation resistance of the upper end of the baffle 54 increases, and the baffle 54 is likely to be always open or always closed. When always open, it cannot block the odor, and when always closed, it affects the drainage of the floor; the second square tube 52 can be removed from between the first square tube 51 and the third square tube 53, and then the baffle 54 in the second square tube 52 can be replaced or repaired, and then the second square tube 52 can be reinstalled.

[0026] As an implementation method, both ends of the second square tube 52 are sealedly connected to the first square tube 51 and the second square tube 52 respectively through flanges.

[0027] Through the above arrangement, the second square tube 52 and the first square tube 51 , as well as the second square tube 52 and the third square tube 53 , have good sealing properties and are not prone to water leakage.

[0028] The upper end of the first square tube 51 and the lower end of the third square tube 53 of the present application are both provided with a first flange extending outward, and both ends of the second square tube 52 are both provided with a second flange extending outward. The second flanges at both ends of the second square tube 52 are fastened to the corresponding first flanges by bolts. In order to increase the sealing performance, a sealing ring can be installed between the first flange and the second flange.

[0029] As an implementation method, a first ear plate 6 is fixedly connected to the inner wall of the upper side of the second square tube 52, and a second ear plate 7 is fixedly connected to the upper end of the baffle 54. The first ear plate 6 is rotatably connected to the second ear plate 7 through a rotating shaft 8.

[0030] Through the above arrangement, the baffle 54 is hinged to the upper inner wall of the second square tube 52 through the first ear plate 6 , the rotating shaft 8 and the second ear plate 7 .

[0031] As an implementation method, the rear outer wall or the front outer wall of the first square tube 51 is tangent to the outer wall of the standpipe body 3 .

[0032] Through the above arrangement, the vibration and noise of the riser structure are reduced.

[0033] like Figure 4 As shown, after the domestic water on the floor is discharged from the first square pipe 51, it is basically discharged to the inner wall of the vertical pipe body 3 along the tangential direction to reduce the impact of the domestic water on the vertical pipe body 3, thereby reducing the vibration and noise of the vertical pipe body 3.

[0034] As an implementation method, the filtering mechanism 4 includes a partition 41 , on which a plurality of filtering holes 42 are provided, and which covers the upper end of the standpipe body 3 .

[0035] The partition 41 of the present application is made of stainless steel and is not easy to rust. The partition 41 is provided with a long strip filtering hole 42 to facilitate the falling of rainwater. At the same time, the partition 41 can block larger foreign objects to prevent foreign objects from clogging the standpipe body 3.

[0036] As an implementation method, the outer diameter of the partition 41 is larger than the outer diameter of the upper end of the riser body 3.

[0037] The above arrangement further prevents foreign matter from entering the riser body 3 .

[0038] As the usage time increases, more and more foreign matter is accumulated on the upper side of the partition 41, which may easily affect drainage. It is troublesome to directly clean the foreign matter on the partition 41. In reality, the partition 41 is usually lifted up first, and then the foreign matter on the upper side is poured out. The partition 41 of the present application has a large area. After the partition 41 is lifted up, there is basically no foreign matter around the upper end of the riser main body 3, forming a circle of clean area, which prevents foreign matter around the partition 41 from falling into the riser main body 3 after the partition 41 is lifted up. After cleaning the foreign matter on the partition 41, the partition 41 is covered back on the upper end of the riser main body 3.

[0039] As an implementation method, the filtering mechanism 4 further includes a handle 43 fixedly connected to the upper side of the partition 41 .

[0040] Through the above arrangement, it is convenient to lift the partition 41 through the handle 43 so as to clean foreign matter on the upper side of the partition 41.

[0041] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to this utility model.
