Description

Technical Field

[0001] This utility model relates to the field of energy-saving building technology, and in particular to an energy-saving roof structure for green buildings. Background Technology

[0002] Green building, as an important way to conserve energy, reduce emissions, and minimize environmental impact, has been widely promoted and applied. As a crucial component of a building, the structural design of the roof has a significant impact on the overall performance of a green building.

[0003] Traditional building roof structures have a relatively simple function, mainly serving to shelter from wind and rain and protect the building's interior space. In terms of energy utilization, most roofs do not fully consider the collection and conversion of renewable energy sources such as solar and hydropower.

[0004] To address this issue, an existing patent application (202320429332.6) describes a green building roof structure that utilizes rotatable solar panels to convert solar energy into electrical energy, thus improving solar energy utilization. Drainage pipes are also installed on the roof to collect rainwater into a storage chamber. While this structure makes full use of natural resources, it still has certain drawbacks.

[0005] For example, as rainwater washes over the roof, it carries away fallen leaves, dust, and other debris, which then enters the drainage pipes. This debris not only severely pollutes the collected rainwater, making it difficult for the water to meet the standards for direct use and increasing the cost and difficulty of subsequent purification treatment; but it also easily accumulates and tangles inside the pipes, causing blockages and severely affecting the efficiency of rainwater collection. Utility Model Content

[0006] This utility model aims to at least partially solve one of the technical problems in related technologies. To this end, this utility model proposes an energy-saving roof structure for green buildings.

[0007] The technical solution to the technical problem solved by this utility model is as follows:

[0008] This utility model proposes an energy-saving roof structure for green buildings, comprising: at least one set of photovoltaic modules placed on the roof, each photovoltaic module including several sets of base frames, on which several sets of photovoltaic panels are arranged closely along the axial direction of the several sets of base frames; a rainwater collection assembly, at least one set of rainwater collection assemblies placed on the side of the photovoltaic panels, each rainwater collection assembly including a connected guide box and a water storage tank, the guide box having a water inlet channel, and a filter plate being arranged in the water inlet channel; a water diversion assembly, the water diversion assembly being closably connected to the top of the guide box via a drive assembly, the water diversion assembly being equipped with a rainwater sensor, the rainwater sensor being controlled and connected to the drive assembly; and a water pump, the water pump being connected to several sets of water storage tanks via water pipes.

[0009] Preferably, the diversion assembly includes two symmetrical unit plates, the outer sides of which are hinged to the top surface of the diversion box; the drive assembly includes at least one set of drive motors placed on the side wall of the water storage tank, the output shaft of the drive motor passes through the water storage tank and is connected to a crank rod, and two sets of guide rods are hinged on the crank rod, the other ends of the two guide rods being respectively hinged to the bottom surface of the unit plate.

[0010] Preferably, a rotatable shaft is connected to the base frame, and several sets of photovoltaic panels are detachably connected to the shaft, with the photovoltaic panels arranged along the axis of the shaft.

[0011] Preferably, a rotating motor is connected to one of the base frames, the rotating motor is connected to the rotating shaft, and several sets of base plates are fixedly connected to the rotating shaft, with the photovoltaic panels detachably connected to the base plates.

[0012] Preferably, the photovoltaic panel is circumferentially connected to a protective frame, and the protective frame is detachable from the base plate via a bolt assembly.

[0013] Preferably, cultivation boxes are installed outside the water storage tanks located on both sides of the roof, and vegetation is planted in the cultivation boxes.

[0014] Preferably, the water storage tank is provided with an openable and closable top cover; the incubator is provided with several sets of absorbent cotton strips, and the other end of the absorbent cotton strips is placed inside the adjacent water storage tank through the opening of the top cover.

[0019] 1. In this invention, a photovoltaic panel is combined with a rainwater harvesting component. In terms of energy utilization and rainwater diversion, the photovoltaic panel efficiently captures solar energy and converts it into electrical energy. Furthermore, during rainfall, it acts as a diversion device, guiding rainwater to a designated area using its tilt angle. The rainwater harvesting components on both sides allow the photovoltaic panel to precisely divert rainwater into the storage tank. Simultaneously, the diversion component, filter plate, and drive component located above effectively intercept rainwater that does not meet utilization standards, ensuring the high quality of the collected rainwater.

[0039] Example 1

[0040] like Figures 1 to 4As shown, this embodiment proposes an energy-saving roof structure for green buildings, which includes at least one set of photovoltaic modules a placed on the roof. Each photovoltaic module a includes several sets of base frames 1, on which several sets of photovoltaic panels 3 are mounted, closely arranged along the axial direction of the base frames 1. It also includes a rainwater harvesting assembly b, with at least one set of rainwater harvesting assemblies b placed beside the photovoltaic modules a. Each rainwater harvesting assembly b includes a connected guide box 8 and a water storage tank 7. The guide box 8 is located above the water storage tank 7 and has a water inlet channel with a filter plate 9 installed inside. It also includes a water diversion assembly, which is closably connected to the top of the guide box 8 via a drive assembly. A rainwater sensor 23 is installed on the water diversion assembly and is controlled by the drive assembly. Finally, it includes a water pump 14, which is connected to several water storage tanks 7 via water pipes 13. Using this water pump 14, rainwater can be selectively stored in the water storage tanks 7 or transported to end-users.

[0041] Traditional roofs typically only have simple drainage systems that drain rainwater directly away, failing to collect and reuse this water resource. This not only wastes water resources but also exacerbates the water burden in some water-scarce areas.

[0042] Based on this, the design combines photovoltaic panels 3 with rainwater harvesting components b, resulting in significant benefits. Firstly, photovoltaic panels 3 achieve efficient power generation while simultaneously allowing rainwater to flow back, greatly expanding their utility and enabling multi-functional use of roof space. Secondly, the rainwater harvesting components b designed on both sides effectively guide rainwater into the storage tank 7, significantly improving the efficiency and stability of rainwater harvesting.

[0043] Based on this, a diversion component is also installed on the top of the water storage tank 7. When the rain is in the early stage, the rainwater washes over these photovoltaic panels 3 and easily carries away debris such as fallen leaves and dust from the photovoltaic panels 3 directly into the water storage tank 7. Although the filter plate 9 can filter out larger debris, it cannot purify the rainwater mixed with dust. This part of the water quality is difficult to meet the standard for direct use. Therefore, the diversion component is used to divert this initial rainwater. After a certain period of time, the diversion component is opened to store the rainwater that meets the use standard into the water storage tank 7.

[0044] Specifically, the diversion assembly includes two symmetrical unit plates 19, with the outer sides of the unit plates 19 hinged to the top surface of the diversion box 8. The aforementioned drive assembly includes at least one set of drive motors 20 placed on the side wall of the water storage tank 7. The drive motors 20 are electrically connected to the rain sensor 23. After passing through the water storage tank 7, the drive motors 20 are connected to a crank rod 21. Two sets of guide rods 22 are hinged to the drive plate, and the other ends of the two guide rods 22 are respectively hinged to the bottom surface of the unit plate 19.

[0045] This design utilizes a rain sensor 23 to capture rainfall signals in real time and obtain rainfall information. The system has a pre-programmed code; based on extensive environmental monitoring data and practical application experience, the rainwater on the photovoltaic panel 3 generally reaches a usable water quality standard within 5-15 minutes after rainfall begins. At this time, the rain sensor 23 quickly sends an electrical signal to the drive motor 20, which in turn rotates the crank, pushing the guide rod 22 upwards. The guide rod 22 further opens the unit plate 19 hinged to the water storage tank 7, thereby collecting usable rainwater. When the rain sensor 23 does not capture a rainfall signal, it sends an electrical signal to the drive motor 20, which resets the two unit plates 19, thus sealing the top of the drainage box 8 and preventing fallen leaves or dust from entering the water storage tank 7.

[0046] In this embodiment, the water storage tanks 7 can be interconnected via connecting pipes. Connecting the water storage tanks 7 located in the middle allows drainage to be achieved through a single water pipe 13. This design effectively reduces the number of water pipes 13 used and avoids occupying too much space. Referring to Figure 3, two sets of photovoltaic modules a are installed on the roof. When the number of photovoltaic modules a is increased, the total number of water pipes 13 in the water storage tanks 7 needs to be increased accordingly, which will increase the cost.

[0047] refer to Figure 4 In this embodiment, the filter plate 9 is arranged at an angle. This allows trapped debris to automatically slide down to the bottom along the surface of the filter plate 9 under gravity, thus keeping the space above the filter plate 9 unobstructed and allowing rainwater to flow smoothly into the water storage tank 7. This design effectively avoids the problem of rainwater flow being obstructed due to debris clogging the filter plate 9, greatly improving the efficiency of rainwater collection.

[0048] Specifically, limiting blocks 11 are respectively installed on the two opposite inner walls of the flow guide box 8, with the two limiting blocks 11 distributed vertically, allowing the filter plate 9 to be installed at an angle on the limiting blocks 11. This design makes the replacement of the filter plate 9 more convenient, allowing for quick replacement without complicated tools and procedures. At the same time, the waste naturally slides down under gravity, facilitating its centralized processing, reducing cleaning difficulty and time, and effectively improving the maintenance efficiency of the flow guide box 8.

[0049] In this embodiment, the bottom of the water storage tank 7 is designed with an inclined structure, with the side where the water pipe 13 is located being the lower end of the bottom surface. This structure can utilize gravity to cause rainwater in the water storage tank 7 to converge towards the water pipe 13, which can significantly improve drainage efficiency.

[0050] In practical applications, this design not only increases access to natural resources but also improves the efficiency of water collection and utilization, providing a more comprehensive solution for green buildings in terms of energy conservation, emission reduction, and comprehensive resource utilization. It aligns with the concept of sustainable development and has promising prospects for widespread application.

[0051] Example 2

[0052] like Figure 1 or Figure 6 As shown, based on Example 1, the photovoltaic panel 3 is configured to be rotatable, so that it can be kept perpendicular or nearly perpendicular to the sunlight to a greater extent, thereby maximizing the power generation effect.

[0053] In this embodiment, a rotatable shaft 2 is connected to the base frame 1. Several sets of photovoltaic panels 3 are detachably connected to the shaft 2, and the photovoltaic panels 3 are arranged along the axis of the shaft 2. A rotating motor 4 is connected to one set of base frames 1. In this embodiment, the structure of the base frame 1 is not limited. The base frames 1 in the middle and at both ends can also be used as supports. A bearing is connected between the base frame 1 and the shaft 2. By supporting the bearing with the base frame 1, deformation of the shaft 2 due to excessive load can be effectively prevented. Furthermore, a protective frame 6 is connected circumferentially to the photovoltaic panels 3. The protective frame 6 is detachably connected to the base plate 5 by bolt assembly.

[0054] In this embodiment, a rotating motor 4 drives a rotating shaft 2 and a photovoltaic panel 3 connected to the rotating shaft 2 to rotate. By rotating the rotating shaft 2 along a preset motion trajectory, the photovoltaic panel 3 is automatically and dynamically adjusted to keep it perpendicular or nearly perpendicular to the sunlight within an allowable range, thereby maximizing the power generation efficiency and achieving the maximum power generation effect.

[0055] When photovoltaic panels 3 are damaged due to unexpected situations such as hail, based on this design, replacement work can be carried out on individual damaged photovoltaic panels 3 while maintaining uninterrupted power supply to the system, and the entire replacement process can be completed within 10 minutes.

[0056] Example 3

[0057] like Figure 1 or Figure 4 As shown, based on Example 1 and adhering to the concept of green health, this example includes planting a certain amount of vegetation 16 on the roof to enhance the greening effect. Specifically, cultivation boxes 15 are set outside the water storage tanks 7 located on both sides of the roof. The cultivation boxes 15 are planted with vegetation 16. By cultivating the vegetation 16, the ecological benefits of the building are improved, and the aesthetics of the building are also enhanced.

[0058] Furthermore, in this embodiment, the top of the water storage tank 7 is open, and a closable top cover 10 is provided on the water storage tank 7. The top cover 10 can be hinged to the top of the water storage tank 7 to achieve closure of the top of the water storage tank 7. To facilitate opening the top cover 10, a handle 12 is connected to the top of the top cover 10. The operator only needs to pull the handle 12 to open the top cover 10, and then perform water quality testing or cleaning and other maintenance work inside the water storage tank 7.

[0059] Inside the cultivation box 15, several sets of absorbent cotton strips 17 are evenly arranged. One end of each cotton strip 17 is buried in the soil inside the cultivation box 15, and the other end passes through the opening between the top cover 10 and the water storage tank 7, hanging naturally inside the adjacent water storage tank 7. This design fully utilizes the rainwater collected in the water storage tank 7. Through capillary action, the rainwater rises along the absorbent cotton strips, continuously moistening the soil inside the cultivation box 15, providing a stable and sufficient water supply for the plants 16 planted within, and automatically irrigating the plants 16. This greatly eliminates the tedious process of frequent manual watering of the plants 16, effectively reducing labor input and maintenance costs. This allows the entire green building's energy-saving roof structure to achieve an efficient and environmentally friendly organic combination of water resource utilization and plant 16 maintenance.

[0060] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
