Nowadays, it is necessary to plant greenery on the garage structure roof to correspond to the concept of green building.

[0003] However, the drainage problem of the garage structure roof is an important factor affecting the safety of the garage structure. The existing structure roof has low drainage efficiency and incomplete drainage, which can easily cause root rot of planted vegetation. At the same time, the garage roof will leak due to excessive water accumulation, affecting the structural strength of the garage. Utility Model Content

[0004] The purpose of the present utility model is to provide a large-area garage structure roof drainage system to solve the problems raised in the above-mentioned background technology.

[0005] A roof drainage system for a large-area garage structure includes a guide portion, an exhaust portion is provided in the guide portion, the guide portion surrounds the exhaust portion, a collecting portion is connected below the guide portion, and an external discharge device is provided in the collecting portion;

[0006] The diversion part comprises, from top to bottom, planting soil, filter stones, geotextile and hydrophobic plate.

[0007] Preferably, the exhaust portion is a cylindrical exhaust hole, and the guide portion also includes a concentrically arranged filter outer ring and a filter inner ring, both of which penetrate the filter stone, geotextile and hydrophobic plate, and the filter stone is filled between the filter inner ring and the filter outer ring.

[0008] Furthermore, the diameter of the outer filter ring is larger than that of the inner filter ring.

[0009] Furthermore, the collecting part includes a cup-shaped water collecting hopper, which is arranged at the bottom of the inner filter ring. The cup-shaped water collecting hopper is connected to a sedimentation tank. A diversion pipe is opened on the side of the sedimentation tank, and the diversion pipe is connected to the accumulated water collection tank.

[0010] Furthermore, the external discharge device includes a sewage pump, which is fixedly connected to the bottom of the accumulated water collection tank and is electrically connected to an automatic switch device.

[0012] Furthermore, an observation plate is fixedly connected to the top of the exhaust hole, and the observation plate is made of a transparent material.

[0013] Furthermore, the guide pipe is opened at the upper edge of the sedimentation tank.

[0014] Compared with the prior art, the utility model has the following beneficial effects: the diversion part of the utility model is paved with planting soil, filter stones, geotextile and hydrophobic plates in sequence, and rainwater can flow down quickly through the planting soil in the filter stone layer until it reaches the hydrophobic plate at the bottom. The hydrophobic plate adopts a honeycomb hydrophobic plate, which is more conducive to the flow of water and facilitates the collection of water to the cup-shaped water collecting bucket, making the filtration of accumulated water more thorough and accelerating the discharge of accumulated water. At the same time, it reduces the weight of the garage roof and reduces the risk of leakage of the garage roof. The filter outer ring is arranged to penetrate the enclosing filter stones, geotextile and hydrophobic plates, and the filter stones are filled between the filter outer ring and the filter inner ring. The filter stones and the two layers of filter rings can effectively block the planting soil from flowing into the collection part with the water to prevent blockage.

[0015] The collecting part of the utility model is provided with a water reservoir to accumulate water for sedimentation, so that the accumulated water is filtered twice, thus preventing the system from being blocked and damaged and ensuring the drainage speed.

[0016] The exhaust section not only serves as a monitoring device for water accumulation on the garage roof, but also provides a pressure differential to activate the siphon system, effectively activating the system and accelerating the water flow. This prevents the accumulation of small particles that could cause blockage and damage to the system, allowing for more thorough drainage of accumulated water. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The following will be combined with specific embodiments and attached Figure 1-3 , clearly and completely describe the technical solutions in the embodiments of the present utility model.

[0022] A large-area garage structure roof drainage system includes a diversion part 1, which is arranged on the top layer of the garage structure roof. The diversion part 1 includes planting soil 11, filter stones 12, geotextiles 13 and hydrophobic plates 14 laid in sequence from top to bottom. The planting soil 11 is located on the top, and green plants can be planted to increase greening. The filter stones 12 under the planting soil 11 are distributed up and down according to different diameter levels, that is, they can filter water quality and prevent soil and water loss. The gaps between the filter stones 12 can ensure air permeability. A geotextile 13 is laid at the bottom of the filter stones 12. The geotextile 13 has high water permeability, which can ensure that rainwater flows smoothly and can also ensure air permeability. At the same time, its holes are very small, which can completely prevent the planting soil 11 from being lost with rainwater. A hydrophobic plate 14 is laid under the geotextile 13. The hydrophobic plate 14 is honeycomb-shaped. The honeycomb-shaped hydrophobic plate 14 is a prior art with strong water permeability, which can facilitate the water collected at the bottom layer to pass through the hydrophobic plate 14 and be collected to the drainage position.

[0023] The guide portion 1 is provided with an exhaust portion 2, which is opened in the guide portion 1. The exhaust portion 2 includes a cylindrical barrel-shaped soil cover 22, which is set through the planting soil 11 to prevent the planting soil 11 from entering the exhaust portion 2. The lower part of the guide portion 1 is connected with a collecting portion 3, which is also connected to the exhaust portion 2 directly below the exhaust portion 2. The exhaust portion 2 is a cylindrical exhaust hole 21. The guide portion 1 also includes a concentrically arranged filter outer ring 15 and a filter inner ring 16. The diameter of the filter outer ring 15 is greater than The inner filter ring 16 and the outer filter ring 15 are outside. The outer filter ring 15 passes through the filter stone 12, the geotextile 13 and the hydrophobic plate 14, and the outer filter ring 15 and the exhaust part 2 are concentrically arranged. The outer filter ring 15 is used to prevent soil from flowing out of the filter stone 12, the geotextile 13 or the hydrophobic plate 14 layer. The inner filter ring 16 is concentrically arranged inside the outer filter ring 15. The filter stone 12 is filled between the outer filter ring 15 and the inner filter ring 16, which can filter and purify the sewage flowing from the guide part 1 to the collection part 3 below the exhaust part 2.

[0024] The entire diversion portion 1 is in the shape of a funnel with the exhaust portion 2 as the center and a low center, which can better collect rainwater and has a small overall slope. The diversion portion 1 includes a cup-shaped water receiving bucket 31, which is connected to the bottom of the filter inner ring 16. The cup-shaped water receiving bucket 31 is conducive to collecting and draining rainwater. The lower part of the cup-shaped water receiving bucket 31 is connected to a sedimentation tank 32 through a pipe. A diversion pipe 33 is provided on the side of the sedimentation tank 32. The diversion pipe 33 is provided on the upper side of the sedimentation tank 32. At the edge, the rainwater entering the sedimentation tank 32 accumulates and the water level gradually rises. The silt will be deposited at the bottom of the sedimentation tank 32 because of the water. When the water level rises to the diversion pipe 33, the silt-free water can flow out from the diversion pipe 33. The diversion pipe 33 is connected to the water collection tank 34. The silt-free water after sedimentation in the sedimentation tank 32 will flow into the water collection tank 34 for storage and can be reused for watering flowers or construction, which can save water resources.

[0025] The water collection tank 34 is provided with an external discharge device 4, which includes a sewage pump 41. The sewage pump 41 is fixedly connected to the bottom of the water collection tank 34. The sewage pump 41 is electrically connected to an automatic switch device 411. The automatic switch device 411 includes an automatic switch including a slide 412 fixedly connected to the sewage pump 41. A slider 413 is slidably connected in the slide 412. A touch switch 415 is fixedly connected to the top of the slide 412. The slider 413 can slide freely in the slide 412. The slider 413 can slide freely in the slide 412. 13 is connected to a float 414 through a flexible line. The buoyancy of the float 414 in the water is greater than the gravity of the slider 413. When the water level rises, the float 414 will slide upward along the slide 412 under the action of the water buoyancy. When the slider 413 slides to the top and touches the touch switch 415, the sewage pump 41 can be turned on to drain water. The sewage pipe discharges the water in the water collection tank 34 through the drain pipe 42, which can automatically control the water level in the water collection tank 34 and prevent the accumulated water from seeping in.

[0026] An observation plate 23 is fixedly connected to the top of the exhaust hole 21. The observation plate 23 is fixedly connected to the soil cover 22. The observation plate 23 is made of transparent material, and the blockage of the cup-shaped water receiving bucket 31 can be observed from the outside.
