Description

Technical Field

[0001] This utility model relates to the field of photovoltaic building technology, and in particular to a waterproof integrated connection device for photovoltaic tiles and roof structures. Background Technology

[0002] With the promotion of building-integrated photovoltaics (BIPV) technology, photovoltaic tiles, capable of simultaneously generating electricity and providing roof protection, are increasingly widely used in the construction industry. However, existing methods of connecting photovoltaic tiles to roofs have significant drawbacks, hindering their further development. Traditional connections often employ simple overlapping or direct bolt fixing, resulting in weak waterproofing. Gaps between the photovoltaic tiles and the roof structure, as well as between the photovoltaic tiles themselves, easily become channels for rainwater infiltration. During heavy rains and strong winds, leaks occur frequently, not only affecting the building's internal environment but also causing corrosion and damage to the roof structure, significantly shortening the building's lifespan. Furthermore, insufficient structural stability means the roof bears long-term wind loads... Due to snow load and the self-weight of photovoltaic tiles, traditional rigid fixing methods are difficult to adapt to the thermal expansion and contraction caused by temperature changes, which can easily lead to loosening and deformation of the connection parts, or even cause the photovoltaic tiles to fall off, posing a serious safety hazard. In addition, they have poor compatibility and maintainability. Different roof structures have different requirements for connection devices, and traditional devices lack adaptive designs. Installation requires a lot of roof modifications, which increases costs and damages the original waterproofing system. Moreover, frequent repairs of leaks and reinforcement of loose parts are required later, making maintenance complex, costly, and affecting power generation efficiency. Therefore, the development of an integrated connection device that is reliable in waterproofing, structurally stable, highly adaptable, and easy to maintain has become an urgent need in the industry.

[0012] 2. This utility model achieves flexible movement through the connecting shaft. The device does not require extensive modification to the roof and can adapt to different types of roof structures, reducing construction costs. Moreover, the connection of each component is reliable. During later maintenance, only targeted inspection and replacement of damaged parts are required, reducing maintenance complexity and costs. At the same time, it avoids the impact of frequent maintenance on the power generation efficiency of photovoltaic tiles, ensuring long-term stable power generation benefits. In addition, the waterproof plate with grooves and locking blocks achieves a quick disassembly effect, and damaged panels can also be disassembled and replaced individually.

A photovoltaic panel fixing seat 4 is provided at the top of the frame 2, and photovoltaic tiles 5 are fixedly installed on both sides of the photovoltaic panel fixing seat 4. The photovoltaic panel fixing seat 4 is used to fix the photovoltaic tiles 5, ensuring the stability of the photovoltaic tiles 5 on the roof and enabling the photovoltaic tiles 5 to effectively cooperate with other structures. A water guide channel 6 is provided in the gap between each photovoltaic tile 5 to guide water flow and organize the drainage of rainwater falling on the roof, preventing water accumulation and penetration, and enhancing the waterproof effect. A fixing shaft 7 is fixedly connected inside the frame 2, mainly for... The waterproofing membrane 8 and other components are fixed and positioned to ensure that they are relatively stably connected to the frame and other structures, thus maintaining the integrity of the integrated waterproofing structure. The outer surface of the frame 2 is provided with the waterproofing membrane 8, an important waterproofing component. Together with the photovoltaic tile 5 and the water channel 6, it forms a waterproofing system that covers part of the roof area and prevents rainwater from seeping into the building. The roof beam 1 is fixedly connected to the house 9, and the outer wall of the house 9 is fixedly connected to the energy storage box 10, which is used to store the electrical energy generated by the photovoltaic tile 5. It has functions such as energy conversion, temporary storage, and protection, which facilitates the subsequent use and management of electrical energy and ensures the stability of the power system.

It also makes the line layout neat and easy to maintain. A groove 12 is opened on one side of the waterproofing membrane 8, and a clip 13 is fixedly connected to the other side of the waterproofing membrane 8.

[0017] Please see Figures 1-3The frame 2 is made of metal, which has high strength and corrosion resistance, ensuring the overall structural stability of the device.
