[0002] Roof drainage is a crucial functional system in housing construction. It is mainly responsible for the timely and effective removal of liquid substances such as rainwater and melted snow accumulated on the roof. Through properly designed drainage facilities such as drainage gutters, rainwater pipes, drains, rainwater buckets, etc., the water on the roof is guided to the ground drainage system or specific drainage areas. Roof drainage has many important functions and benefits. It can effectively prevent water accumulation on the roof, prevent rainwater from leaking into the interior of the building, protect the roof structure and interior decoration and furniture from water damage, and extend the service life of the building. Good drainage can keep the indoor environment dry and comfortable, reduce the growth of mold, and provide a healthy environment for residents;
[0003] Roof drainage for buildings usually consists of drainage gutters, rainwater pipes, rainwater buckets, and drainage ditches. Drainage gutters are used to collect rainwater from the edge of the roof. Rainwater pipes transport rainwater from the gutters to the ground. Rainwater buckets are installed on the gutters or roofs to effectively intercept debris and guide rainwater into the pipes. Drainage ditches serve as auxiliary drainage and centralized drainage.
[0004] However, the drainage of traditional roofs of buildings is easily blocked by debris such as leaves, branches, and garbage, especially in autumn when there are many fallen leaves. Debris can easily enter the drainage system, causing pipe blockage and affecting the drainage effect. Once the pipe is blocked, rainwater cannot be discharged in time and will accumulate on the roof, increasing the load on the roof. Therefore, a roof drainage device for buildings is proposed to solve the above problems. Utility Model Content

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0034] Reference Figure 1-Figure 3 , the utility model provides an embodiment: a roof drainage device for a building, including a parapet 1, which plays a role in protecting personnel safety and preventing rainwater from overflowing directly from the edge of the roof. The parapet 1 is fixedly connected to a structural layer 2 inside the parapet, which plays a role in bearing vertical loads and can withstand huge pressure. The upper surface of the structural layer 2 is fixedly connected to an insulation layer 3, which adopts polystyrene foam board to have the advantages of light weight, low thermal conductivity, good thermal insulation performance, low water absorption, and low temperature resistance. The insulation layer 3 can make the temperature inside the building more stable and reduce temperature fluctuations. The upper surface of the insulation layer 3 is fixedly connected to a slope layer 4, which provides a certain inclination angle for the surface layer 6, so that rainwater falling on the roof can flow quickly to the drain outlet. The upper surface of the slope layer 4 is fixedly connected to a waterproof layer 5, which adopts a polymer modified asphalt waterproof membrane to prevent rainwater, snow water, etc. from flowing in. When rainwater seeps into the building, the upper surface of the waterproof layer 5 is fixedly connected to the surface layer 6, and the surface layer 6 is provided with a left-right symmetrical drainage ditch 7 so that the accumulated water can flow quickly. A plurality of grooves 9 are provided inside the drainage ditch 7 to reduce the impact of the water flow and make the rainwater flow more smoothly in the drainage ditch 7, reducing the splashing of water. A geotextile 8 is laid inside the drainage ditch 7 to effectively prevent the fine particles around the drainage ditch 7 from entering the drainage ditch 7 with the water flow. A net 10 is fixedly connected inside the drainage ditch 7 to further filter out large particles and impurities that the geotextile 8 cannot filter out to prevent the rainwater pipe 24 from being blocked. A diversion pipe 11 is fixedly connected to one side of the surface layer 6 to introduce the accumulated water on the surface of the surface layer 6 into the rainwater gutter 13. A drainage component is provided on one side of the parapet 1 to discharge the rainwater inside the diversion pipe 11.
[0035] Specifically, when the rainfall is heavy, a large amount of rainwater will flow into the drainage system in a short period of time, or when there is a lot of dust and particulate impurities in the air, the parapet 1 is used to block and effectively prevent people from falling from the edge of the roof. The insulation layer 3 reduces and prevents the transfer of heat, thereby improving the energy utilization efficiency of the building and reducing energy consumption during heating in winter and cooling in summer. The slope layer 4 provides a suitable slope to ensure that rainwater can flow smoothly to the drainage system and prevent the occurrence of water accumulation. The waterproof layer 5 extends the service life of the building by blocking water penetration. The drainage ditch 7 opened inside the roof surface layer 6 can efficiently collect and discharge accumulated rainwater. At the same time, the multiple grooves 9 opened inside can change the speed and flow distribution of the water flow and optimize the drainage effect. In addition, a layer of geotextile 8 laid on the surface has a good effect in filtering fine particles and impurities. The permeability of the geotextile 8 protects the drainage system and avoids blockage. Furthermore, the net 10 is used to further remove larger impurity particles, which is convenient for cleaning and maintenance, keeping the roof drainage system clean and efficient.
[0036] Reference Figure 4-Figure 6The drainage assembly includes a support plate 12 and a rainwater bucket 13, which are made of stainless steel and have excellent corrosion resistance. The support plate 12 is fixedly connected to one side of the parapet 1, and one side of the rainwater bucket 13 is fixedly connected to one side of the support plate 12. The outer wall of the bottom end of the rainwater bucket 13 is slidably connected with a bent plate 2 19, which is used to fixedly connect the rainwater bucket 13 and the rainwater pipe 24. A rotating column 2 18 is fixedly connected to the inside of one side of the bent plate 2 19, and the outer wall of the rotating column 2 18 is rotatably connected to a connecting block 17. The connecting block 17 is rotatably connected to a rotating column 16 inside, which is used to drive the bent plate 15 to rotate. The outer wall of the rotating column 16 is fixedly connected to the bent plate 15, and one side of the bent plate 15 is rotatably connected to a rotating shaft 23.
[0037] Specifically, when the rainwater pipe 24 and the rainwater gutter 13 need to be quickly installed, disassembled and maintained, after the rainwater is collected on the roof, it will flow into the rainwater gutter 13 through the guide pipe 11. The operator manually fits the bottom end of the rainwater gutter 13 with the rainwater pipe 24 to ensure that the rainwater can flow smoothly into the pipe. At the same time, the operator needs to turn the lever 21, which is connected to the connecting plate 22. The lever principle makes the connecting plate 22 rotate on one side of the bent plate 15. Driven by this action, the fixing frame 20 is driven to perform synchronous displacement inside the bent plate 2 19.
[0038] Reference Figure 4-Figure 6 The outer wall of the rotating shaft 23 is fixedly connected to a connecting plate 22, and one side of the connecting plate 22 is fixedly connected to a lever 21 for transmitting the pressure applied by the operator to drive the fixing frame 20 to move. The connecting plate 22 is internally rotatably connected to the fixing frame 20, and one side of the fixing frame 20 is rotatably connected to the inside of the bent plate 2 19. The inner sides of the bent plate 2 19 and the bent plate 1 15 are fixedly connected with a plurality of suction cups 14, which are made of silicone material, making them soft, high temperature resistant, low temperature resistant, and chemically stable, so as to better protect the rainwater pipe 24 and the rainwater bucket 13 from being squeezed and damaged. The bent plate 2 19 is internally slidably connected to the rainwater pipe 24, and the rainwater pipe 24 fits well with the rainwater bucket 13.
[0039] Specifically, at the same time, the pulling force of the fixing frame 20 causes the bent plate 15 and the bent plate 2 19 to shrink inward at the same time, generating an extrusion force. This extrusion force exerts effective pressure on the rain gutter 13 and the rain pipe 24, ensuring that the suction cup 14 can be firmly attached to their outer walls. In this process, the suction cup 14 fixes the rain gutter 13 and the rain pipe 24 together through a strong adsorption force, avoiding damage caused by the extrusion force, and providing additional safety for the entire drainage system, ensuring the stability and durability of each component, and effectively preventing the rain gutter 13 and the rain pipe 24 from being damaged by external forces during use, while ensuring the smooth discharge and collection of rainwater, thereby improving the overall waterproofing and drainage performance of the building.
[0040] Working principle: The roof drainage device of the house can effectively prevent people from falling from the edge of the roof through the parapet 1, reduce and prevent heat transfer through the insulation layer 3, and improve the energy utilization efficiency of the building. The slope layer 4 and the waterproof layer 5 provide a suitable slope to prevent rainwater and other moisture from penetrating into the interior of the building. At the same time, the drainage ditch 7 opened inside the surface layer 6 can effectively collect and discharge the accumulated rainwater, and the speed and flow distribution of the water flow can be changed through the multiple grooves 9 opened inside it. At the same time, a layer of geotextile 8 laid on its surface can effectively filter fine particles and impurities, and the larger impurity particles can be further removed through the net 10. In order to achieve the effect of convenient cleaning, rainwater will flow into the rain gutter 13 through the diversion pipe 11. The operator manually fits the bottom end of the rain gutter 13 with the rain pipe 24, and then moves the lever 21 to drive the connecting plate 22 to rotate on the side of the bent plate 15, thereby driving the fixing frame 20 to rotate inside the bent plate 2 19 and perform synchronous displacement. The pulling force will cause the bent plate 15 and the bent plate 2 19 to shrink inward at the same time to generate an extrusion force. Through this extrusion force, the suction cup 14 is firmly attached to the outer wall of the rain gutter 13 and the rain pipe 24, further protecting the rain gutter 13 and the rain pipe 24 from damage by the extrusion force, and firmly fixing them at the same time.
[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
