Description

Technical Field

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

[0002] With the popularization of green building concepts, the functionality and energy efficiency of roofs, as an important component of building envelopes, have received widespread attention. Traditional building roofs have a single function, only providing basic shelter from wind and rain, and have many limitations: for example, during rainfall, rainwater is mostly discharged directly through conventional drainage systems, lacking effective collection and utilization of rainwater resources, resulting in a large waste of water resources.

[0003] Therefore, roof structures capable of recycling rainwater have emerged on the market. For example, a green building energy-saving roof with patent application number 202422659705.6 has water collection components installed on the sloping sides of the roof panel, and filter plates are installed inside the water collection components to filter out larger impurities before collecting them again. However, this method still has certain drawbacks. For example, the roof is exposed to the elements for a long time, and the surface of its roof panel is prone to accumulating dust, fallen leaves, bird droppings, and other debris. Although the filter plates can filter out large particles such as liquids, the rainwater in the initial stage of rainfall still carries pollutants, forming high-turbidity runoff. Directly flowing into the drainage pipes not only reduces the water resource recycling rate but also increases the burden of subsequent purification treatment. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in related technologies. To this end, this utility model proposes a green building energy-saving roof structure.

[0005] The technical solution to the technical problem solved by this utility model is as follows:

[0006] This utility model proposes a green building energy-saving roof structure, including a roof body composed of two inclined top plates and a roof cover plate. A rain collection box is provided above the roof cover plate, and a collection port is also provided at the bottom of the top plate. A guide plate is connected to the inner side of the top plate by a rotatable shaft, and the guide plate is driven to rotate within the collection port by a drive component provided on the top plate, realizing the switching between rain collection state and closed state. A guide channel is fixed to the inner side of the bottom of the guide plate. One side of the guide channel is closed by a sealing plate, and the other side is open, so as to guide the rainwater in the guide channel to the rain collection box.

[0007] Preferably, a flow guide tarpaulin is connected between the flow guide plate and the inner side of the collection port, and the flow guide tarpaulin and the flow guide plate form a flow guide channel for controlling the flow direction of the collected rainwater.

Rotatable composite photovoltaic panels are installed inside the light-collecting openings, and the composite photovoltaic panels are switched between open light-collecting and closed light-guiding states by a rotating component.

[0011] Preferably, the composite photovoltaic panel includes a protective plate and a photovoltaic panel body distributed vertically. In the closed flow-guiding state, the top surface of the protective plate and the top surface of the top plate are on the same plane. In the open light-receiving state, the photovoltaic panel rotates and leaks into the sunlight.

[0012] Preferably, the composite photovoltaic panel has a rotating rod at the bottom, with both ends of the rotating rod rotatably connected to both sides of the light-collecting opening.

[0014] Preferably, an incubation box is provided on each of the two sides above the roof slab, and green vegetation is planted in the incubation box.

[0015] Preferably, the guide channel is provided with drip holes for drip irrigation of the green vegetation in the incubator.

[0016] The above technical solution has the following advantages or beneficial effects:

[0017] 1. This utility model utilizes the dynamic adjustment of the guide plate to achieve timed collection of rainwater: In the early stage of rainfall, the guide plate is flush with the top plate, discarding rainwater carrying pollutants; in the later stage, the guide plate rotates to form an angle, intercepting clean rainwater into the guide channel, and finally flowing into the rainwater collection box, thereby ensuring that the collected rainwater meets the water quality standards for secondary use, significantly improving the utilization rate of rainwater resources, and at the same time greatly reducing the cost and pressure of subsequent purification treatment.

[0035] Example 1

[0036] like Figure 1 or Figure 4 As shown, this embodiment proposes a green building energy-saving roof structure, which includes a roof body formed by two inclined roof slabs 1, a roof cover plate, and side baffles. A rainwater collection box 14 is set above the roof cover plate to collect clean rainwater resources for secondary use. It also includes a collection port 2 opened below the roof slab 1 and a guide plate 3. The guide plate 3 and the inner side of the roof slab 1 are connected to a rotatable shaft 4, and the guide plate 3 is driven to rotate in the collection port 2 by a drive component 7 set on the roof slab 1, realizing the switching between the open and closed states of the guide plate 3. It also includes a guide channel 5, which is fixed to the inner side of the bottom of the guide plate 3. One side of the guide channel 5 is closed by a sealing plate, and the other side is open and aligned with the rainwater collection box 14, so as to guide the rainwater in the guide channel 5 into the rainwater collection box 14.

[0037] This invention achieves efficient rainwater diversion and graded collection through a flip-up guide plate 3. The inclined top plate 1 serves as the initial diversion surface, which, together with the flip-up guide plate 3, forms a rainwater interception structure: after flipping, the guide plate 3 and the top plate 1 form a specific angle, guiding the rainwater along the guide plate 3 to the lower diversion channel 5, and finally into the rainwater collection box 14.

[0038] To address the issue of high-turbidity runoff caused by rainwater carrying dust, fallen leaves, bird droppings, and other debris during the initial stages of rainfall, this invention employs a dynamic adjustment technology using a guide plate 3 to achieve phased rainwater collection: During the initial rainfall phase, the guide plate 3 remains flush with the top plate 1, allowing the initial rainwater carrying pollutants to be directly discharged, thus completing the runoff rejection; after a certain flushing time, the drive assembly 7 controls the guide plate 3 to rotate within a range of 0°-120°, forming a cutoff angle with the top plate 1, guiding subsequent clean rainwater into the guide channel 5. This ensures that the rainwater flowing into the collection tank 14 meets the secondary utilization standards, effectively improving rainwater resource utilization and reducing the pressure on subsequent purification treatment.

[0039] When rainfall is heavy, rainwater flowing downwards along the top plate 1 may directly impact the guide plate 3 and the rotating shaft 4, causing splashing and preventing it from being effectively collected into the guide channel 5. Therefore, in this embodiment, a guide tarpaulin 6 is connected between the inner sides of the guide plate 3 and the collection port 2. This guide tarpaulin 6 and the guide plate 3 form a guide channel for controlling the flow direction of the collected rainwater, ensuring that the rainwater smoothly flows into the guide channel 5 along a preset path, thus improving the reliability of rainwater collection under extreme weather conditions.

[0040] In this embodiment, the drive assembly 7 includes a drive motor 71 connected to the inner side of the top plate 1, a drive gear 72 connected to the output shaft of the drive motor 71, and a driven gear 73 sleeved on one side of the rotating shaft 4. The driven gear 73 meshes with the main gear and drives the rotating shaft 4 and the guide plate 3 to rotate.

[0041] Furthermore, bearing seats 74 are connected to both sides of the top plate 1, and a rotating shaft 4 is connected between the two bearing seats 74; a clearance opening 75 is provided on one side of the top plate 1, and the aforementioned driving gear 72 and driven gear 73 are both located in the clearance opening 75.

[0042] In this design, the rotating shaft 4 is positioned along the center of the guide plate 3, so that the top surface of the guide plate 3 forms a flow interception surface and the bottom surface forms a flow guide surface, allowing rainwater to smoothly collect and flow into the guide channel 5. To minimize the impact of the rotating shaft 4 on rainwater collection, the rotating shaft 4 is designed to fit against the guide plate 3 and the inner side of the top plate 1. This design prevents the motor output shaft from being directly connected to the rotating shaft 4, and instead, it is driven by the meshing of the driving gear 72 and the driven gear 73. To avoid affecting the transmission of the driving gear 72 and the driven gear 73, a clearance opening 75 is provided on the inner side of the top plate 1, providing complete space for the driving gear 72 and the driven gear 73 to move.

[0043] Example 2

[0044] This implementation incorporates energy-saving design based on Example 1, achieving synergy between solar energy utilization and rainwater diversion through the following structure:

[0045] refer to Figures 3 to 6 Several sets of light-collecting openings 10 are provided on the top plate 1. The light-collecting openings are arranged in a linear array above the collection port 2. A rotatable photovoltaic panel is installed in the light-collecting opening 10, and the photovoltaic panel is switched between open light-collecting and closed light-guiding states by the transmission component 8.

[0046] On cloudy or rainy days, the composite photovoltaic panel 9 rotates to a closed flow-guiding state, with the upper surface and the top panel 1 forming a continuous flow-guiding surface, directing rainwater to the collection port 2, and then through the guide plate 3 into the flow channel 5, achieving efficient collection of rainwater resources. On sunny days, the composite photovoltaic panel 9 rotates to an open light-receiving state, with the bottom surface of the panel facing the direction of sunlight, converting light energy into electrical energy through the photovoltaic effect, forming a dual-function integrated system of "lighting and power generation and rainwater guidance".

[0047] In this embodiment, the composite photovoltaic panel 9 includes a protective plate and a photovoltaic panel body distributed vertically. In the closed flow-guiding state, the top surface of the protective plate and the top surface of the top plate 1 are on the same plane to guide rainwater. In the open state, the photovoltaic panel body rotates and leaks into the sunlight to collect light energy.

[0048] In this embodiment, the composite photovoltaic panel 9 has a rotating rod 11 at its bottom, with both ends of the rotating rod 11 rotatably connected to the two sides inside the light-collecting opening 10; the transmission assembly 8 includes an ear plate 81 connected to the rotating rod 11, and a through hole 82 is provided on the ear plate 81; it also includes two rotating motors 83 placed inside the top plate 1, and several sets of composite photovoltaic panels 9 are placed between the two rotating motors 83. The output shaft of the rotating motor 83 is connected to a hinge shaft 84, and a drive rope 85 is wound between the two hinge shafts 84. The drive rope 85 passes through and is located inside the through hole 82. Several sets of limiting discs 86 are also connected to the drive rope 85, and the limiting discs 86 are respectively located on both sides of the ear plate 81.

[0049] This design employs a drive rope 85 to achieve synchronous rotation of several sets of composite photovoltaic panels 9. The top-mounted rotary motor 83 is activated, driving the winch 84 to rotate and wind up the drive rope 85. During winding, the drive rope 85 pulls the limiting disc 86 upwards, which in turn drives the composite photovoltaic panels 9 to rotate around the axis of the rotating rod 11, achieving coordinated action of multiple photovoltaic panels and opening them. When a closed flow-guiding state is required, the bottom-mounted rotary motor 83 is activated, pulling the drive rope 85 to wind up around the lower winch, thereby resetting the composite photovoltaic panels 9.

[0050] It is worth noting that rubber seals are connected around the perimeter of the composite photovoltaic panel 9, and a rubber rain shield is fixed to the bottom outer side of the composite photovoltaic panel 9 to seal the light-transmitting opening 10 and prevent rainwater from leaking onto the roof through the gap between the composite photovoltaic panel 9 and the light-transmitting opening during rainfall.

[0051] Example 3

[0052] refer to Figure 6 Based on Embodiments 1 and 2, cultivation boxes 12 are respectively set on both sides above the roof slab, and green vegetation 13 is planted in the cultivation boxes 12. The green vegetation 13 can beautify the visual effect of the roof and form a three-dimensional building system; at the same time, it can release sunlight and absorb air pollutants through photosynthesis, thus improving the surrounding environment.

[0053] Furthermore, a drip hole is provided on the guide channel 5, which is used for drip irrigation of the green vegetation 13 inside the incubator 12. Figure 3 As shown, when the guide plate 3 rotates to the rain collection state, the guide channel 5 is located above the incubator 12, and some of the collected clean rainwater is dripped into the incubator 12 to irrigate the green vegetation 13 inside, making full use of rainwater resources and reducing some manual labor.

[0054] On the other hand, when the composite photovoltaic panel 9 is rotated to the open light-receiving state, the light-receiving opening 10 opens simultaneously, and sunlight can shine directly on the vegetation below through the light-receiving opening 10, forming a three-dimensional light energy utilization of photovoltaic power generation and vegetation lighting.

[0055] 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.
