Description

Technical Field

[0001] The present application relates to the field of roof technology, and in particular to green roofs of urban buildings. Background Art

[0002] Green building stems from the need and desire for more energy-efficient and environmentally friendly building practices, including environmental, economic and social benefits. It generally emphasizes the use of renewable resources, such as sunlight through passive solar and photovoltaic equipment, to reduce environmental loads and optimize systems.

[0003] Existing green roofs do not filter rainwater accurately enough when collecting it, resulting in a large amount of impurities in the collected rainwater. This, in turn, can cause impurities to easily enter the water pump when it is running to water the vegetation on the roof, causing damage to the water pump and blockage of the water pipes. Utility Model Content

[0004] In view of the deficiencies of the prior art, the present invention provides a green roof for urban buildings, which overcomes the deficiencies of the prior art and aims to solve the problems in the background technology.

[0005] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme: a green roof of an urban building, comprising a roof body, a water tank is provided on the top of the roof body, a filter plate 1 is fixedly installed on the inner wall of the water tank, a number of leakage holes are evenly provided on the inner wall of the filter plate 1, a fixed frame is fixedly installed on the top of the roof body, a frame is fixedly installed on the inner wall of the fixed frame, the top of the frame is rotatably connected to the filter plate 2, a slide is slidably connected to the inner wall of the fixed frame, a support plate is fixedly installed on the top of the fixed frame, a motor is fixedly installed on the outer side of the support plate, a power output shaft of the motor is fixedly connected to a gear, a rack is fixedly connected to the side of the slide close to the gear, an opening is provided on the top of the fixed frame, a baffle is inserted into the inner wall of the opening, and the top of the filter plate 2 is filled with a number of gravel layers of different shapes and sizes.

[0006] As a preferred embodiment, four convex grooves are symmetrically provided on both sides of the fixed frame, and the inner walls of the four convex grooves are slidably connected with convex bars, and the outer sides of the four convex bars are symmetrically fixed with two side panels, and the two side panels are arranged in an inclined shape.

[0007] By adopting the above technical solution, the side panels can be used to guide rainwater, ensuring that on rainy days, rainwater can slide along the inner side of the side panels to the inner cavity of the fixed frame, be filtered through the gravel layer, filter plate one and filter plate two, and then penetrate into the inner cavity of the water storage tank for collection.

[0008] As a preferred embodiment, a limiting groove is opened on the inner wall of the fixed frame, the slide bar and the rack are slidably connected to the inner wall of the limiting groove, the gear and the rack are meshed with each other, and the side of the second filter plate close to the slide bar is rotatably connected to the outer wall of the slide bar.

[0009] By adopting the above technical solution, the rotation of the gear can utilize the rack to drive the slide bar to slide on the inner wall of the limit groove, thereby pulling the filter plate 2 into an inclined state, so that when the baffle is separated from the inner wall of the opening, the gravel layer can be dumped to the outside through the opening, thereby facilitating the removal of the gravel layer for replacement and cleaning.

[0010] As a preferred embodiment, a water pump is fixedly installed in the inner cavity of the water storage tank, and the output end of the water pump is fixedly connected to a water pipe.

[0011] By adopting the above technical solution, the water pump can be driven to discharge the water collected in the inner cavity of the water storage tank to the outside through the water pipe, and then the collected rainwater can be sprayed onto the vegetation layer, thereby improving the utilization rate of rainwater and reducing the pressure on urban domestic water use.

[0012] As a preferred embodiment, the inner wall of the second filter plate is provided with a plurality of drain holes, and the inner wall diameters of the plurality of drain holes are larger than the inner wall diameter of the leakage hole.

[0013] By adopting the above technical solution, rainwater filtered through the gravel layer can contact the filter plate 2 and then penetrate into the surface of the filter plate 1 through the drainage hole, and then be filtered again through the leakage hole before being discharged into the inner cavity of the water storage tank for collection.

[0014] As a preferred embodiment, the bottom of the opening and the top of the second filter plate are in the same plane, and a handle is fixedly mounted on the top of the baffle.

[0015] By adopting the above technical solution, when the filter plate 2 is in an inclined state, the gravel layer accumulated on the filter plate 2 can be quickly poured out through the opening to the outside, which improves the convenience and thoroughness of removing the gravel layer.

[0016] Beneficial effects of this application:

[0017] 1. On the green roof of the urban building, rainwater is initially filtered through the gravel layer, and then penetrates through the gravel layer to the surface of the filter plate two for secondary filtration. After being filtered three times through the filter plate, it is collected into the inner cavity of the water storage tank, ensuring the thoroughness and fineness of the rainwater filtration, and avoiding the problem that impurities are easily entered into the water pump when the water pump is running to water the vegetation on the roof, causing damage to the water pump and blockage of the water pipe. The gear is driven by the driving motor to rotate, and then the rack is used to drive the slide bar to pull the end of the filter plate two close to the slide bar upward, and then it is in an inclined state. At the same time, the gravel layer can roll down through the opening along the slope formed by the filter plate two to the external storage container, thereby facilitating the replacement or cleaning of the gravel layer.

[0018] 2. The green roof of the urban building can guide rainwater by setting side panels, ensuring that rainwater can slide along the inner side of the side panels to the inner cavity of the fixed frame and be filtered through the gravel layer on rainy days, thereby improving the efficiency of rainwater collection. The convex grooves and convex strips can facilitate the installation and removal of the side panels. BRIEF DESCRIPTION OF THE DRAWINGS

Then, it penetrates through the gravel layer 17 to the surface of the filter plate 2 9 for secondary filtration. Then, it passes through the filter plate 1 5 for three filtrations and is collected into the inner cavity of the water tank 2. Then, the water pump 3 can be driven to discharge the water collected in the inner cavity of the water tank 2 to the outside through the water pipe 4, and then the collected rainwater is sprayed onto the vegetation. layer, thereby improving the utilization rate of rainwater and reducing the pressure of domestic water use in the city. The baffle 16 is removed from the inner wall of the opening 15 by pulling the handle, and then the motor 12 can be driven to drive the gear 13 to rotate, and then the rack 14 can be used to drive the slide bar 10 to pull the filter plate 2 9 close to the end of the slide bar 10 to move upward, and then it is in an inclined state. At the same time, the gravel layer 17 can follow the slope formed by the filter plate 2 9 through the opening 15 to the outside storage container, thereby facilitating the replacement and cleaning of the gravel layer 17.
