Description

Technical Field

[0001] This utility model relates to the field of roof drainage technology, and in particular to a drainage roof. Background Technology

[0002] Roof drainage refers to the organized discharge of rainwater, snowmelt, and other water from the roof to the ground or underground drainage system. By installing a certain slope, drainage gutters, downspouts, and rainwater pipes on the roof, gravity is used to allow rainwater to quickly drain away from the roof along a predetermined path.

[0003] Its purpose is to prevent rainwater from accumulating on the roof, avoid roof leaks and water accumulation from damaging the building, protect the structural safety of the building and the indoor environment, extend the service life of the building, and at the same time keep the surrounding environment clean and dry.

[0004] For example, Chinese Patent Publication No. (CN215291025U) discloses a roof drainage structure, which describes: "It includes a drainage ditch and a plurality of drainage tiles. The drainage ditch is located below the intersection of the inner corners of two roofs and is arranged along the length of the intersection of the inner corners of the two roofs. The plurality of drainage tiles are laid above the drainage ditch along the length of the drainage ditch. The roof drainage structure according to the embodiment of this utility model can effectively prevent rain leakage from the building roof."

[0005] In summary, the drainage structure also has the following technical problems: the structure achieves rainwater drainage by laying the gutter tiles at the four corners, but because the gutter tiles are obtuse-angled, with one side tightly attached to the roof and the other side extending to the outside of the roof, rainwater is concentrated and guided by the gutter tiles when it rains. However, if someone passes under the eaves, the gutter tiles do not have a centralized discharge outlet, which will cause the person passing under to get wet. Therefore, it is necessary to propose a drainage roof and provide a new technical solution to solve the technical problems mentioned in the above patent. Utility Model Content

[0006] Therefore, it is necessary to provide a drainage roof to address the above-mentioned technical problems. By setting up a drainage structure, the surface of the roof is sloped at 1 to 3 degrees. Rainwater flows around the slope to the inside of the water barrier and is collected through a water collection trough. After being collected in the water collection trough, it is discharged in a unified manner through a drain pipe and a collection pipe. This can prevent a large amount of rainwater from flowing out from the outer edge of the house.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] A type of drainage roof.

[0009] The drainage roof specifically includes the main body of the house, and also includes the roof set on the upper part of the main body of the house. The outer periphery of the roof is provided with a drainage structure, and the interior of the drainage structure is provided with an emergency overflow structure.

[0010] The drainage structure includes a water-blocking edge fixedly connected to the perimeter of the roof. The surface of the water-blocking edge is covered with a foreign object isolation net. A water collection trough is fixedly connected inside the water-blocking edge and is located at the bottom end of the foreign object isolation net.

[0011] As a preferred embodiment of the drainage roof provided by this utility model, drainage pipes are fixedly connected to the four corners of the water-blocking edge, a collection pipe is fixedly connected to the bottom end of the drainage pipe, a drainage outlet is opened on the surface of the drainage pipe, and a protective top cover is fixedly connected to the top end of the drainage pipe.

[0012] In a preferred embodiment of the drainage roof provided by this utility model, a guide ring is fixedly connected inside the drainage pipe, a water storage ring is provided inside the drainage pipe, the bottom end of the water storage ring is slidably connected to the inside of the guide ring, and multiple drainage holes are opened inside the water storage ring.

[0013] In a preferred embodiment of the drainage roof provided by this utility model, an overflow pipe is fixedly connected to the surface of the collection pipe, and the end of the overflow pipe away from the collection pipe is fixedly connected to the inside of the water collection tank.

[0014] In a preferred embodiment of the drainage roof provided by this utility model, the surfaces of the drainage pipe and the overflow pipe are provided with grooves, the overflow pipe is slidably connected to a movable adjusting pipe, the surface of the movable adjusting pipe is provided with an overflow outlet, and the lowest end of the overflow outlet is three centimeters higher than the lowest end of the drainage outlet.

[0015] In a preferred embodiment of the drainage roof provided by this utility model, a return spring is provided inside the guide ring. The two ends of the return spring are fixedly connected to the guide ring and the water storage ring, respectively. A horizontal connecting rod is fixedly connected to the surface of the water storage ring. The end of the horizontal connecting rod away from the water storage ring is fixedly connected to the surface of the movable adjusting pipe. The horizontal connecting rod is slidably connected to the inner wall of the groove.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The drainage roof provided by this utility model has a drainage structure with a slope of 1 to 3 degrees on the surface of the roof. Rainwater flows around the slope to the inside of the water barrier and is collected by the water collection trough. After being collected by the water collection trough, it is discharged in a unified manner through the drainage pipe and the collection pipe. This can prevent a large amount of rainwater from flowing out from the outer edge of the house.

[0018] The drainage roof provided by this utility model has an emergency overflow structure. If the water storage ring cannot drain the water in time due to excessive rainfall, the water storage ring will descend and pull the movable regulating pipe down to below the water level line through the horizontal connecting rod. At this time, the rainwater inside the water collection tank can be discharged through the overflow port on the surface of the movable regulating pipe, thereby effectively increasing the drainage speed of the drainage structure when the rainfall is too heavy.

[0019] The drainage roof provided by this utility model, by setting up an adjustable pipe, if the drain outlet on the surface of the drain pipe becomes blocked, the water level will gradually rise to be level with the overflow outlet. At this time, drainage can be assisted through the overflow outlet, thereby effectively avoiding the problem of drainage difficulties caused by blockage. Attached Figure Description

[0028] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0029] As in the background art, this structure achieves rainwater drainage by laying the gutter tiles at the four corners. However, since the gutter tiles are obtuse in shape, with one side tightly attached to the roof and the other side extending to the outside of the roof, rainwater is concentrated and guided by the gutter tiles when it rains. However, if someone passes under the eaves, the person passing under will get wet because the gutter tiles do not have a centralized discharge outlet.

[0030] To solve this technical problem, this utility model provides a drainage roof.

[0031] For details, please refer to Figures 1-3 The drainage roof specifically includes the main body of the house 1, and also includes the roof 2 set on the upper part of the main body of the house 1. The outer periphery of the roof 2 is provided with a drainage structure 3, and the interior of the drainage structure 3 is provided with an emergency overflow structure 4.

[0032] The drainage structure 3 includes a water-blocking edge 5 fixedly connected to the four sides of the roof 2. The surface of the water-blocking edge 5 is covered with a foreign object isolation net 6. A water collection trough 7 is fixedly connected inside the water-blocking edge 5 and is located at the bottom of the foreign object isolation net 6.

[0033] The drainage roof provided by this utility model has a drainage structure 3 and a slope of 1 to 3 degrees on the surface of the roof 2. Rainwater flows around the slope to the interior of the water-blocking edge 5 and is collected by the water collection trough 7. After being collected by the water collection trough 7, it is discharged in a unified manner through the drainage pipe 8 and the collection pipe 9. This can prevent a large amount of rainwater from flowing out from the outer edge of the house.

[0034] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Example 1

[0035] Please refer to Figures 2-4 A drainage roof includes a main body 1 and a roof 2 disposed on the upper part of the main body 1. A drainage structure 3 is disposed on the outer periphery of the roof 2 and an emergency overflow structure 4 is disposed inside the drainage structure 3.

[0036] The drainage structure 3 includes a water-blocking edge 5 fixedly connected to the four sides of the roof 2. The surface of the water-blocking edge 5 is covered with a foreign object isolation net 6. A water collection trough 7 is fixedly connected inside the water-blocking edge 5 and is located at the bottom of the foreign object isolation net 6.

[0037] Specifically, drain pipes 8 are fixedly connected to the four corners of the water-blocking edge 5, a collection pipe 9 is fixedly connected to the bottom end of the drain pipe 8, a drain outlet 10 is opened on the surface of the drain pipe 8, and a protective top cover 11 is fixedly connected to the top end of the drain pipe 8.

[0038] Specifically, a guide ring 12 is fixedly connected inside the drain pipe 8, and a water storage ring 13 is provided inside the drain pipe 8. The bottom end of the water storage ring 13 is slidably connected to the inside of the guide ring 12, and multiple drain holes 14 are opened inside the water storage ring 13.

[0039] With the above structural design, when it rains, rainwater drips onto the surface of the roof 2 and flows into the interior of the surrounding water-blocking channel 5 through the slope of the roof 2 surface. The rainwater flows into the interior of the water collection trough 7 and is collected. The collected rainwater flows into the interior of the drain pipe 8 through the drain outlet 10 on the surface of the drain pipe 8. The rainwater flows into the interior of the water storage ring 13 and is discharged into the interior of the collection pipe 9 through the drain hole 14. Example 2

[0040] The drainage roof provided in Example 1 is further optimized, specifically, as follows: Figures 4-5 As shown, an overflow pipe 16 is fixedly connected to the surface of the manifold 9, and the end of the overflow pipe 16 away from the manifold 9 is fixedly connected to the inside of the water collection tank 7.

[0041] Specifically, the surfaces of the drain pipe 8 and the overflow pipe 16 are provided with grooves 17, the overflow pipe 16 is slidably connected to a movable regulating pipe 18, the surface of the movable regulating pipe 18 is provided with an overflow port 19, and the lowest end of the overflow port 19 is three centimeters higher than the lowest end of the drain port 10.

[0042] Specifically, a return spring 15 is provided inside the guide ring 12. The two ends of the return spring 15 are fixedly connected to the guide ring 12 and the water storage ring 13 respectively. A horizontal connecting rod 20 is fixedly connected to the surface of the water storage ring 13. The end of the horizontal connecting rod 20 away from the water storage ring 13 is fixedly connected to the surface of the movable regulating tube 18. The horizontal connecting rod 20 is slidably connected to the inner wall of the slide groove 17.

[0043] With the above structural design, when the rainfall continues to increase, the drainage hole 14 inside the water storage ring 13 cannot discharge the rainwater in time. At this time, the rainwater continues to accumulate inside the drainage pipe 8, and its weight continues to increase, squeezing the water storage ring 13 and causing it to slide downward inside the drainage pipe 8 and compress the return spring 15. As the water storage ring 13 descends, it drives the movable regulating pipe 18 to move downward inside the overflow pipe 16 through the horizontal connecting rod 20, so that the overflow port 19 on the surface of the movable regulating pipe 18 reaches below the horizontal plane. At this time, the rainwater can be transported to the inside of the collection pipe 9 through the overflow pipe 16 and discharged. At the same time, it can effectively reduce the drainage pressure of the drainage pipe 8 alone, and the overflow pipe 16 can still drain normally after the drainage pipe 8 is blocked.
