[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0019] Figure 1 This is a schematic diagram of the structure of the present invention. Figure 1 ;

[0020] Figure 2 This is a schematic diagram of the structure of the present invention. Figure 2 ;

[0021] Figure 3 For the present invention Figure 1 A schematic diagram of the structure at point A. Detailed Implementation

[0022] Figures 1-3 As shown in the figure, the roof system with green vegetation in this embodiment includes a modular roof tray 1. The modular roof tray 1 has a vegetation layer 12, a substrate layer 13, a filter layer, a drainage layer 15 and a water storage layer arranged from top to bottom.

[0023] In this scheme, the modular roof tray 1 includes a tray shell 11 with an open top. The drainage layer 15 is located inside the tray shell 11 and divides the internal space of the tray shell 11 into a vegetation space and a water storage space. The vegetation layer 12, the substrate layer 13 and the filter layer are set in the vegetation space, and the water storage space is used as the water storage layer 16.

[0024] Specifically, the drainage layer 15 includes a concave-convex drainage plate with drainage holes, which is detachably fixed inside the tray housing 11. The concave-convex drainage plate is selected from any existing technology suitable for this solution, and drainage holes are pre-drilled or added later. The drainage holes are located on the raised parts of the concave-convex drainage plate, which will not be elaborated further here. The use of the concave-convex drainage plate provides a certain water storage function in the grooved area, combining drainage and water storage capabilities, ensuring that the green vegetation neither accumulates water nor suffers from water shortage, thus improving the survival rate of the green vegetation.

[0025] In this embodiment, the filter layer includes a geotextile layer 1401 for separating the matrix layer 13 and the drainage layer 15, and a filling layer 1402 for supporting the geotextile layer 1401. The filling layer 1402 has a certain water permeability and the ability to block sand, gravel and particles in the matrix layer 13. Preferably, materials such as sponge, acrylic cotton or sand and gravel can be used as the filling layer 1402. In this solution, the filling layer 1402 includes sand and gravel laid on top of the drainage layer 15, so that the filter layer also has a certain support capacity. The geotextile layer 1401 is any geotextile suitable for this solution in the prior art, laid on the top surface of the sand and gravel, and the periphery of the geotextile extends upward, so that the geotextile surrounds and forms a trough-shaped space with an open top. The vegetation layer 12 and the matrix layer 13 are arranged in the trough-shaped space.

[0026] In this embodiment, the vegetation layer 12 and the substrate layer 13 are laid from top to bottom within the trough-shaped space. The substrate layer 13 can utilize a lightweight growth medium, selected based on the growth characteristics of the planted plants, such as rice husks, vermiculite, expanded clay, peat moss, synthetic foam or rock wool, or polyacrylonitrile fiber flocculent material. This substrate is thin, has a light load, and offers better durability and water retention. This special substrate layer requires no management, allowing the green plants to grow healthily under natural climatic conditions. The plant layer can be planted with shallow-rooted plants such as sedum, grasses, and small shrubs, improving survival rates and facilitating maintenance.

[0027] In this embodiment, the modular roof trays 1 are in several groups, arranged along a predetermined path. Adjacent modular roof trays 1 are detachably connected, and the water storage layers 16 of the several groups of modular roof trays 1 are interconnected. The modular green roof trays feature a diverse and flexible design, enabling quick installation, safe construction, and simple and convenient construction. They are also easy to transport, install, and dismantle. Compared with existing technologies, this invention can be used for green vegetation roof construction in complex situations where material transportation is difficult, ensuring high efficiency in green vegetation roof construction, saving manpower, materials, and other resources, and reducing costs. This invention has a simple structure, is manufactured in a production workshop, and assembled on-site without additional fixing. It does not affect other construction procedures or completed construction projects, and can be quickly dismantled and replaced later, saving manpower and financial resources. In this solution, the modular roof trays 1 are connected horizontally and vertically to form a large-area roof. In practical applications, they can be arranged to form numbers, letters, or predetermined shapes, which will not be elaborated further here.

[0028] In this embodiment, the modular roof tray 1 has a connecting part I 31 and a connecting part II 32. Adjacent modular roof trays 1 are connected by mortise and tenon joints through corresponding connecting parts I 31 and II 32. The mortise and tenon joint connection method has the function of quick disassembly and assembly, is convenient to implement, and has good tensile strength after the structure is fitted. Specifically, the connecting part I 31 extends outward from the side wall of the tray shell 11 and has a clamp-shaped structure with an open front end. The connecting part I 31 has an assembly cavity located inside the open end and communicating with the open end. In this embodiment, the assembly cavity is cylindrical. The connecting part II 32 extends outward from the side wall of the tray shell 11 and has an assembly part in the outward direction of the connecting part II 32. The assembly part extends outward so that the lateral dimension of the assembly part exceeds that of the connecting part II 32. The shape of the assembly part is consistent with the cavity shape of the assembly cavity and is slightly smaller than the size of the assembly cavity, so that when adjacent modular roof trays 1 are connected, they fit together to form a mortise and tenon joint assembly structure.

[0029] In this embodiment, adjacent modular roof trays 1 are assembled by at least two sets of matching connecting parts I 31 and II 32. The two sets of matching connecting parts I 31 and II 32 are far apart from each other, which improves the connection strength and reliability and avoids relative rotation or displacement of adjacent modular roof trays 1 after connection.

[0030] This embodiment also includes a sprinkler system for supplying water to the green vegetation in the modular roof tray 1. The sprinkler system has a connected inlet and a spray nozzle, and includes a nozzle 41. The inlet is connected to the water storage layer 16, and the outlet is connected to the nozzle 41. In use, the sprinkler system delivers water from the water storage layer 16 to the nozzle 41 to irrigate a preset area. The sprinkler system also includes a power source and pipes connecting the inlet and the spray nozzle. In this embodiment, the power source is an external power system connected to a water pump. By using the water from the water storage layer 16 to irrigate the green vegetation, a self-circulating water system is created, saving on irrigation costs.

[0031] In this embodiment, there is a functional gap between adjacent modular roof trays 1, which is formed by the assembly of mortise and tenon joint connecting parts I 31 and II 32; the irrigation mechanism has a water pipe 4 connecting the inlet and outlet, the water pipe 4 is located within the functional gap, and the water pipe 4 is between two sets of matching connecting parts I 31 and II 32 to ensure the performance of the water pipe 4; the water pipe 4 is connected downward to the water storage layer 16, and the nozzle 41 is set above the water pipe 4. The height of the nozzle 41 is higher than the top edge of the modular roof tray 1, so as to make the application range wider and suitable for irrigation of green vegetation.

[0032] In this embodiment, the sprinkler mechanism further includes a lifting component, which is used to raise and lower the sprinkler head 41 in the height direction. This broadens the applicability of the sprinkler head 41 to vegetation of different heights. Furthermore, in this design, a sprinkler head 41 is installed between every two modular roof trays 1. Each sprinkler head 41 has a valve on its bottom water pipe, which is independently controlled to regulate the water volume and spray speed. This makes it more suitable for rooftop systems with diverse green vegetation. The sprinkler mechanism also includes a rotating component for rotating the sprinkler head 41 and a retracting component for displacing the sprinkler head 41 towards the modular roof tray 1. This reduces the number of sprinkler heads 41 used, improves structural compactness, reduces equipment failure rate, and provides more accurate irrigation, thus increasing vegetation survival rate. The lifting component, rotating component, and retracting component can be any compatible existing technology and electrically connected to the control system. The control system should preferably use any existing technology to achieve the purpose of this design; further details are omitted here. For example, the lifting and retracting components can be selected from any of the following: lifting rod, hydraulic cylinder, or electric cylinder; the rotating components can be selected from any of the following: drive motor or universal joint. These will not be elaborated further here.

[0033] In this embodiment, a temperature and humidity monitoring element 2 is pre-embedded in the substrate layer 13. The temperature and humidity monitoring element 2 is electrically connected to the sprinkler system of the sprinkler mechanism, so that the sprinkler head 41 can be controlled to irrigate and maintain the preset vegetation according to the temperature and humidity information fed back by the temperature and humidity monitoring element 2 pre-embedded in the substrate layer 13, thereby improving the automation capability of irrigation. The irrigation system can be any of the existing technologies to achieve the intended purpose, which will not be elaborated here.

[0034] In this embodiment, the interconnected modular roof trays 1 are connected by any of the existing technologies that are suitable for this solution, and the socket-type waterproof pipe joint 5 is positioned at a lower position, so that the water storage height of several interconnected modular roof trays 1 is consistent, which is beneficial for supplying water to the sprinkler system.

[0035] In this embodiment, several sets of modular roof trays 1 with water storage layers 16 are connected to form a green vegetation system covering the roof. An overflow port 17 connected to the water storage layer 16 is provided on the modular roof tray 1 near the drainage ditch. The overflow port 17 is close to the drainage layer 15. In use, the overflow port 17 is connected to the drainage ditch, which is used to guide the overflow water to the water storage system or the drainage system. In this solution, a water storage tank is also included. The drainage ditch is connected to the water storage tank, and the water storage tank is connected to the water inlet of the irrigation and sprinkler mechanism. Specifically, the water storage tank is connected to the water storage layer 16 to replenish the water storage layer 16. The water storage tank is also connected to an external water source to supply water to the sprinkler assembly when there is insufficient rainwater.

[0036] In this embodiment, an energy system is also included to supply power to the temperature and humidity monitoring element 2, the sprinkler system, and the electrical equipment. The energy system of this solution includes a photovoltaic solar panel 6 and an energy storage device 7, which are green energy sources. The electrical energy is managed by the energy storage device for use when needed, allowing the system to continue operating even when there is no sun. The solar panel and the energy storage device are selected from any of the existing technologies and are electrically connected to the aforementioned electrical equipment using existing processing and control systems to achieve the intended functions, which will not be elaborated further here.

[0037] In this embodiment, the solar panels for photovoltaic power generation are installed on the top cover of the power control station. The top cover can be opened and closed in a controlled manner. It also serves as an inspection port for the maintenance of the internal energy storage equipment and the main water supply pump 8. The power control station is far from the drainage ditch and close to the modular roof tray 1 on the corresponding side. The main water supply pump 8 is also installed inside the power control station. The main water supply pump is controlled by the control system so that the corresponding sprinkler head 41 sprays water to the corresponding green vegetation.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
