Description

Technical Field

[0001] This utility model relates to the field of drainage technology, and in particular to a siphon-type roof rainwater drainage device for large-span airport terminals. Background Technology

[0002] Airports, as transportation hubs connecting various locations, play a vital role in urban development. The terminal building is a landmark structure of the airport, a crucial passageway for travelers. Passengers undergo security checks, baggage check-in, waiting, and transfers here, sometimes experiencing delays of several hours due to weather or aircraft malfunctions. The main terminal building's roof has a complex curved surface, forming several concave lowest points on both the land and air sides, resulting in complex water flow and making rainwater gutters difficult to install. Given these roof characteristics, failure to promptly drain rainwater from the roof would significantly impact the structure, posing a substantial potential hazard. The design incorporates a siphonic rainwater system to effectively remove large volumes of rainwater. This system is arranged in a single-bucket configuration, with indoor rainwater pipes running along the columns to the ground, exiting through closed pipes to the outside and directly into the terminal area's rainwater drainage system.

[0003] Extensive research revealed that existing siphonic rainwater drainage systems only have a filter cartridge on the top surface of the rainwater hopper during operation. While this can filter large impurities, small impurities can still enter the suspension pipe, which can easily cause blockages over time and affect the drainage effect.

[0004] Therefore, it is necessary to provide a siphonic roof rainwater drainage system for large-span terminal buildings to solve the above-mentioned technical problems. Utility Model Content

[0005] This utility model provides a siphon-type rainwater drainage device for large-span terminal building roofs, which solves the problems in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a large-span terminal building siphon-type roof rainwater drainage device, including a roof structure layer and a supporting mechanism. A rainwater hopper is embedded inside the roof structure layer, and a connecting pipe is installed through the rainwater hopper. The top end of the connecting pipe extends to the middle of the rainwater hopper, and an external thread is provided on the top surface of the connecting pipe. A second threaded connecting ring is spirally connected to the top of the connecting pipe, and a second filter cylinder is provided at the top of the second threaded connecting ring. The diameter of the filter holes inside the second filter cylinder is smaller than the diameter of the filter holes inside the first filter cylinder, and the second filter cylinder is positioned in the middle of the rainwater hopper. This allows rainwater to settle first when it enters the rainwater hopper. After the rainwater submerges the second filter cylinder inside the rainwater hopper, it enters the connecting pipe for discharge. The second filter cylinder then performs a second filtration of impurities in the rainwater. This method is simple to operate, ensures normal rainwater discharge, and avoids blockages.

[0007] Preferably, a suspension pipe is installed at the bottom of the connecting pipe, a riser is installed at one end of the suspension pipe, and an outlet pipe is installed at the bottom of the riser. By employing a siphon-type roof rainwater drainage system, in the initial stage of rainfall, when the roof rainwater height does not exceed the height of the rainwater hopper, the entire drainage system operates similarly to a gravity drainage system. As rainfall continues, when the roof rainwater height exceeds the height of the rainwater hopper, the scientifically designed anti-vortex rainwater hopper, by controlling the flow rate of rainwater entering the hopper and adjusting the flow pattern to reduce vortices, greatly reduces the amount of air entrained when rainwater enters the drainage system. This results in the drainage pipes in the system being in a full-flow state. Utilizing the height of the building roof and the potential energy of the rainwater, a siphon effect is formed when the rainwater continuously flows through the rainwater suspension pipe and falls into the rainwater riser, creating maximum negative pressure within the pipe at this point. Under the suction effect of the negative pressure within the pipe, the roof rainwater is discharged outdoors at a high flow rate.

[0008] Preferably, the support mechanism has an arc-shaped support plate inside, a connecting rod is vertically installed at the top of the arc-shaped support plate, a fixing plate is installed at the top of the connecting rod, and fixing holes are opened on the surface of the fixing plate. The fixing plate is fixedly connected to the roof structure layer by fasteners. By setting up the support mechanism, the support performance of the suspended pipe is improved. Moreover, by placing each arc-shaped support plate below the connecting pipe, the impact force of rainwater falling on the connecting pipe can be supported, preventing the impact force of rainwater from damaging the suspended pipe and further improving the service life of the suspended pipe.

[0009] Preferably, the inner wall of the rainwater hopper is provided with an internal thread, and the top of the rainwater hopper is spirally connected to a first threaded connecting ring, and the top of the first threaded connecting ring is provided with a first filter cylinder.

[0010] Preferably, multiple connecting pipes are provided, and the multiple connecting pipes are installed at equal intervals on the top surface of the suspension pipe. By providing multiple connecting pipes, the drainage efficiency of rainwater can be improved.

[0011] Preferably, multiple support mechanisms are provided, and the multiple support mechanisms are installed at equal intervals below the suspension pipe. Each of the arc-shaped support plates is located below the connecting pipe. By providing multiple support mechanisms, the support performance of the suspension pipe can be improved. Moreover, by placing each arc-shaped support plate below the connecting pipe, the impact force of rainwater falling on the connecting pipe can be supported, preventing the impact force of rainwater from damaging the suspension pipe and further improving the service life of the suspension pipe.

[0012] Compared with related technologies, the large-span terminal building siphon roof rainwater drainage device provided by this utility model has the following beneficial effects:

[0013] Compared with existing technologies, the siphonic roof rainwater drainage device for large-span terminal buildings incorporates a second filter cartridge. The diameter of the filter holes in the second filter cartridge is smaller than that in the first filter cartridge, and the second filter cartridge is positioned in the middle of the rainwater hopper. This allows rainwater to settle before entering the hopper, submerging the second filter cartridge before entering the connecting pipe for discharge. The second filter cartridge then performs a second filtration of impurities. This method is simple to operate, ensures proper rainwater drainage, and avoids blockages. The addition of a support mechanism improves the support performance of the suspended pipe, and each arc-shaped support plate is positioned below the connecting pipe to withstand the impact of falling rainwater, preventing damage to the suspended pipe and further extending its service life.
