Description

Technical Field

[0001] This utility model relates to the field of urban drainage facilities, and in particular to a rainwater pipe drainage structure. Background Technology

[0002] The proper placement and installation of rainwater pipes is a crucial aspect of building drainage systems. As an important component of urban building facades, curtain walls not only serve as the building envelope but also play a key role in the building's aesthetics.

[0003] In existing technologies, the outlet of rainwater pipes is generally exposed near the ground, which can easily affect the aesthetics of the building. In addition, the inlet of the rainwater pipe is on the roof, and the high-speed water flow during drainage may impact surrounding facilities or pedestrians. Large-scale drainage may cause the ground to become slippery, increasing the risk of pedestrians slipping and creating safety hazards. Chinese patent CN115653216A discloses a concealed rainwater pipe drainage device and its working method. The rainwater pipe is installed as a whole in the curtain wall facade, maintaining the aesthetics of the building. However, maintenance personnel need to remove the curtain wall facade when inspecting the rainwater pipe, resulting in high maintenance costs. Utility Model Content

[0004] This utility model provides a rainwater pipe drainage structure that optimizes the drainage path of the rainwater pipe, ensuring the overall aesthetics of the curtain wall while reducing drainage safety hazards and maintenance costs of the rainwater pipe.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rainwater pipe drainage structure, comprising: a rainwater pipe, a building curtain wall, a sealing component, and a grass swale; The rainwater pipe is used to transport water. The rainwater pipe includes a first pipe section, a second pipe section, and a third pipe section connected in sequence. The first pipe section and the second pipe section are respectively fixedly connected to the inner side of the building curtain wall. The first pipe section extends along a first direction and has a water inlet that communicates with the outside. The second pipe section extends along a second direction and has a spiral guide vane for deceleration inside. The third pipe section extends along a third direction. The first direction, the second direction, and the third direction are perpendicular to each other. The second pipe section and the third pipe section are respectively located at the bottom of the first pipe section. The building curtain wall has an opening extending along the third direction. The third pipe section passes through the opening and has a water outlet located outside the opening. The sealing assembly is sleeved on the outer periphery of the third pipe segment, and the third pipe segment is fixedly connected to the building curtain wall through the sealing assembly; The grass swale is located on the ground outside the building curtain wall, the grass swale extends along the second direction, and the bottom end of the opening is spaced above the grass swale.

[0006] Preferably, the rainwater pipe drainage structure further includes a water-blocking component, which includes a limiting part and a water-blocking plate. The limiting part is spaced apart on the outside of the building curtain wall and sleeved on the outer periphery of the third pipe section. The limiting part is fixedly connected to the third pipe section. The water-blocking plate is located on the outside of the water outlet and is hinged to the limiting part. The water-blocking plate can cover or leave the water outlet open.

[0007] Preferably, the limiting part includes a clamp, a limiting rod, and a limiting member. The clamp is sleeved on the outer periphery of the third pipe section, the limiting rod is located at the top of the third pipe section, the limiting rod extends along the second direction and passes through the clamp, and the limiting member is installed on both sides of the limiting rod along the second direction to limit the clamp to the limiting rod, thereby completing the fixed connection between the limiting part and the third pipe section. The baffle plate is hinged to the limiting rod.

[0008] Preferably, the water-blocking assembly further includes a hinge, which is sleeved on the limiting rod, and the water-blocking plate is fixedly connected to the hinge.

[0009] Preferably, the baffle plate is an arc-shaped steel plate, and the baffle plate protrudes in a direction away from the water outlet.

[0010] Preferably, the limiting part is spaced 50-60mm from the building curtain wall in the third direction.

[0011] Preferably, the grassed swale includes a swale bottom and a first slope and a second slope located on both sides of the swale bottom along the third direction. The top of the first slope is fixedly connected to the bottom of the building curtain wall, and the top of the second slope is not lower than the top of the first slope.

[0012] Preferably, a planting layer is provided at the top of the second slope and at the top of the ditch bottom, and a gravel layer is provided at the top of the first slope.

[0013] Preferably, the building curtain wall includes a curtain wall panel and a curtain wall keel. The curtain wall panel has the opening.

[0014] Preferably, the sealing component is a rubber sleeve.

[0015] Compared with the prior art, the beneficial effects of this utility model are: After flowing through the first pipe section, the water enters the second pipe section where it is slowed down by a spiral guide vane, and then exits through the third pipe section into the grassed swale. The grassed swale also buffers the water flow, preventing high-speed water from being directly discharged onto the ground and impacting surrounding facilities or people. The spacing between the outlet and the bottom of the grassed swale helps prevent debris in the water flow from clogging the outlet, reducing safety hazards during drainage. At the same time, the grassed swale reduces the abruptness of the outlet protruding from the exterior of the building curtain wall, ensuring the overall aesthetics of the building curtain wall. Only the third pipe section of the rainwater pipe passes through the building curtain wall, while the second pipe, equipped with a spiral guide vane, is located on the interior side of the building curtain wall. This facilitates segmented maintenance of the rainwater pipe and helps reduce maintenance costs. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0021] A rainwater drainage structure includes: a rainwater pipe 1, a building curtain wall 2, a sealing component 3, and a grassed swale 4; the rainwater pipe 1 is used to transport water, as shown in the reference. Figure 1 and Figure 3 ,in Figure 3 For the view from the outside of the building to the inside, the rainwater pipe 1 includes a first pipe section 11, a second pipe section 12, and a third pipe section 13 connected in sequence. The first pipe section 11 and the second pipe section 12 are respectively fixedly connected to the inner side of the building curtain wall 2. The first pipe section 11 extends along a first direction X and has an inlet 111 that communicates with the outside. The second pipe section 12 extends along a second direction Y and has a spiral guide vane 121 for deceleration inside. The third pipe section 13 extends along a third direction Z. The first direction X, the second direction Y, and the third direction Z are all perpendicular to each other. The second pipe segment 12 and the third pipe segment 13 are respectively located at the bottom of the first pipe segment 11. The building curtain wall 2 is provided with an opening 21 extending along the third direction Z. The third pipe segment 13 passes through the opening 21 and is provided with a water outlet 131, which is located outside the opening 21. The sealing component 3 is sleeved on the outer periphery of the third pipe segment 13, and the third pipe segment 13 is fixedly connected to the building curtain wall 2 through the sealing component 3. The grass swale 4 is located on the ground outside the building curtain wall 2 and extends along the second direction Y. The bottom end of the opening 21 is spaced above the grass swale 4.

[0022] For example, the first pipe section 11, the second pipe section 12, and the third pipe section 13 are connected by elbows. During drainage, the water flows from the first pipe section 11 to the second pipe section 12. The spiral guide vane 121 is a spiral body whose outer edge abuts against the inner wall of the second pipe section 12. The spiral body extends spirally in the second direction Y so that after the water enters the second pipe section 12, it will rotate and flow along the spiral direction of the spiral guide vane 121 until it flows out of the second pipe section 12. This increases the path length of the water flow, promotes the dissipation of water flow energy, and effectively reduces the speed of the water flow entering the third pipe section 13. Under the guidance of the spiral guide vane 121, the impact of the water flow on the pipe wall of the second pipe section 12 is reduced. At the same time, it also helps to reduce drainage noise. There is a height difference between the outlet 131 and the bottom of the grass ditch 4, which prevents garbage, fallen leaves, etc. from clogging the outer side of the outlet 131 and causing backflow of water. The grass ditch 4 further buffers the water flow from the third pipe section 13, preventing it from impacting other surrounding facilities or pedestrians and causing safety hazards. It should be noted that the third pipe section 13, as the pipe section connecting the outdoor and indoor sides, not only passes through the building curtain wall 2, but also through the load-bearing building wall on the indoor side of the building curtain wall 2, so that the third pipe section 13 can be connected to the second pipe section 12 indoors. The first pipe section 11 and the second pipe section 12 are both located indoors of the building. The inlet 111 is located at the top of the first pipe section 11 and at the top of the building. For example, the first pipe section 11 is fixedly connected to the building curtain wall 2 through one side of the support column 6 arranged indoors of the building. That is, most of the pipe section of the rainwater pipe 1 is located indoors of the building. The grass swale 4 is set on the outside of the third pipe section 13 to reduce the abruptness of the outlet 131 of the rainwater pipe 1 being exposed outdoors, which is conducive to ensuring the overall architectural style coordination of the exterior of the building curtain wall 2. With this arrangement, only the third pipe section 13 passes through the building curtain wall 2. When maintenance is required, the third pipe section 13 can be replaced by disassembling the sealing component 3 and disconnecting from the second pipe section 12. After the second pipe section 12 is disconnected from the first pipe section 11 and the third pipe section 13, the spiral guide vane 121 can be inspected or replaced, effectively reducing the maintenance cost of the rainwater pipe 1.

[0023] Furthermore, the rainwater pipe drainage structure also includes a water-blocking component 5, which includes a limiting part 51 and a water-blocking plate 52. The limiting part 51 is spaced apart on the outside of the building curtain wall 2. The limiting part 51 is sleeved on the outer periphery of the third pipe section 13. The limiting part 51 is fixedly connected to the third pipe section 13. The water-blocking plate 52 is located on the outside of the outlet 131. The water-blocking plate 52 is hinged to the limiting part 51. The water-blocking plate 52 can cover or leave the outlet 131 open.

[0024] When there is no water flow in rainwater pipe 1, such as Figure 3-4 As shown, the baffle plate 52 covers the outlet 131. When there is water flowing in the rainwater pipe 1, such as Figure 1-2As shown, the water flow automatically opens the baffle plate 52, allowing the water to flow through the third pipe section 13 to the grassed swale 4. The baffle plate 52 can prevent the water flow from splashing too fast and wetting pedestrians around the grassed swale 4.

[0025] Furthermore, the limiting part 51 includes a clamp 511, a limiting rod 512, and a limiting member 513. The clamp 511 is sleeved on the outer periphery of the third pipe section 13. The limiting rod 512 is located at the top of the third pipe section 13. The limiting rod 512 extends along the second direction Y and passes through the clamp 511. The limiting member 513 is installed on both sides of the limiting rod 512 along the second direction Y to limit the clamp 511 to the limiting rod 512, thereby completing the fixed connection between the limiting part 51 and the third pipe section 13. The baffle plate 52 is hinged to the limiting rod 512.

[0026] In some embodiments, the clamp 511 is fitted onto one end of the outlet 131 on the third pipe section 13. The limiting rod 512 is a stainless steel strip with threads on the periphery near both ends and no threads in the middle. The limiting element 513 is a nut. After determining the hinge position between the baffle plate 52 and the limiting rod 512 and the inner side of the clamp 511 fitting against the outer periphery of the third pipe section 13, the limiting element 513 is screwed onto the limiting rod 512 from both ends to complete the clamping installation. The installed baffle plate 52 can rotate around the limiting rod 512 to automatically cover the outlet 131. During disassembly, the connection between the limiting element 513 and the limiting rod 512 is released, and the limiting part 51 and the baffle plate 52 can be removed from the third pipe section 13. This facilitates the operator's disassembly and assembly of the baffle assembly 5.

[0027] Furthermore, the water-blocking assembly 5 also includes a hinge 53, which is sleeved on the limiting rod 512, and the water-blocking plate 52 is fixedly connected to the hinge 53. The water-blocking plate 52 is hinged to the limiting rod 512 via the hinge 53.

[0028] Furthermore, the baffle plate 52 is an arc-shaped steel plate, and the baffle plate 52 protrudes away from the water outlet 131. This arrangement of the baffle plate 52 can guide the high-speed water flow to the grass swale 4, reducing water splashing.

[0029] Furthermore, the limiting part 51 is spaced 50-60mm from the building curtain wall 2 in the third direction Z. This provides operating space for the operator to install the water-blocking component 5, and the outlet 131 should not protrude too far from the exterior of the building curtain wall 2 to avoid affecting the external aesthetics of the building curtain wall 2 and preventing the pipe from freezing and cracking in low-temperature environments. Preferably, the clamp 511 is fitted onto the third pipe at a distance of 50mm from the building curtain wall 2.

[0030] Furthermore, such as Figure 1As shown, the grassed swale 4 includes a swale bottom 41 and a first slope 42 and a second slope 43 located on both sides of the swale bottom 41 along the third direction Z. The top of the first slope 42 is fixedly connected to the bottom of the building curtain wall 2, and the top of the second slope 43 is not lower than the top of the first slope 42. The second slope 43 is the side of the grassed swale 4 away from the outlet 131 along the third direction Z, ensuring that the height of the second slope 43 can effectively shield the third pipe, enhance the concealment of the rainwater pipe 1, and also prevent water from splashing out of the grassed swale 4 when water flows into it.

[0031] Furthermore, a planting layer is provided at the top of the second slope 43 and the top of the ditch bottom 41, and a gravel layer is provided at the top of the first slope 42. The vegetation in the planting layer can retain water flow. For example, planting vegetation of a certain height at the top of the second slope 43 can shield the third pipe section 13 exposed outside the building, thereby improving the overall aesthetics of the exterior of the building curtain wall 2. Ensuring that no vegetation is planted at the top of the first slope 42 helps to avoid vegetation blocking the outlet 131.

[0032] Furthermore, the building curtain wall 2 includes a curtain wall panel 22 and a curtain wall keel 23. The curtain wall panel 22 is provided with the opening 21. The curtain wall keel 23 passes through the curtain wall panel 22 and is fixedly connected to the curtain wall panel 22. At least two sets of the curtain wall keels 23 are spaced apart along the first direction X on both sides of the opening 21.

[0033] In some embodiments, the curtain wall panel 22 includes multiple panels, one of which is provided with an opening 21. Two sets of curtain wall studs 23 are located on both sides of the panel in the first direction X, which helps to enhance the stability of the connection between the rainwater pipe 1 and the building curtain wall 2.

[0034] Reference Figure 3 Furthermore, the sealing component 3 is a rubber sleeve. The third pipe is fixedly connected to the building curtain wall 2 through the rubber sleeve. The rubber sleeve has a certain deformation capacity and can fit the inner side of the opening 21 and the outer side of the third pipe to form a good sealing structure. In some embodiments, refer to Figure 4 The outer diameter of the rubber sleeve is equal to the outer diameter of the water baffle 52. The sealing effect of the sealing component 3 is enhanced by applying waterproof sealant to the rubber sleeve near the outdoor side.

[0035] Based on the disclosure and teachings of the foregoing specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this application is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this application should also fall within the protection scope of the claims of this application. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this application.
