Description

TECHNICAL FIELD

[0001] The utility model belongs to photovoltaic tile installation accessory technical field, concretely relates to a photovoltaic tile structure with equal pressure cavity. BACKGROUND

[0002] With the acceleration of urbanization, land resources become increasingly tight. Photovoltaic tiles can effectively utilize the roof space of buildings, without occupying additional land resources, thereby realizing efficient utilization of land. This has important significance for urban construction and land resource management. Photovoltaic tiles are innovative products that combine photovoltaic cell technology with building materials. They not only have the power generation function of traditional photovoltaic cells, but also have the aesthetics and durability of building materials. Photovoltaic tiles are usually used for roof covering, which can generate electricity and replace traditional roof tiles, thereby realizing green energy utilization and aesthetic effect of buildings.

[0003] The installation of photovoltaic tiles requires close jointing between the tiles to ensure their stability and durability in daily use. However, extreme weather conditions such as strong winds and heavy rains can cause serious impact on photovoltaic tiles. These extreme weather conditions not only cause tile displacement, but also may cause tile damage, thereby causing leakage problems. Long-term leakage can cause corrosion and weakening of the building structure, further reducing the safety and service life of the building. SUMMARY

[0004] Therefore, the utility model provides a photovoltaic tile structure with equal pressure cavity, which can solve the problem of weak wind resistance and easy water seepage of existing photovoltaic panels.

[0005] The utility model is implemented as follows:

[0006] The utility model provides a photovoltaic tile structure with equal pressure cavity, which comprises a photovoltaic panel, a lower horizontal frame, an upper horizontal frame, a windproof hook, a frame, a hook, a tile hanging strip and an equal pressure cavity. A water following strip is fixedly laid on the roof, the tile hanging strip is fixedly connected to the water following strip, the hook is fixedly connected to the upper surface of the tile hanging strip, the hook is connected to the upper horizontal frame through a wedge-shaped rubber pad, the upper horizontal frame is connected to the edge of the photovoltaic panel through the frame, the upper part of the upper horizontal frame is sealed and jointed to the lower horizontal frame through a sealing rubber strip, the upper horizontal frame is slidingly connected to the windproof hook and forms the equal pressure cavity, the lower horizontal frame is fixedly connected to the edge of the photovoltaic panel, the lower horizontal frame and the frame are connected to each other, and the windproof hook is covered on the outside of the frame.

[0007] The technical effect of the photovoltaic tile structure with equal pressure cavity is as follows: 1. The lower horizontal frame and the upper horizontal frame effectively fill the gap between the upper and lower photovoltaic panels, fundamentally blocking rainwater from directly entering the inner cavity of the photovoltaic panel and reducing the risk of component aging caused by moisture.

[0008] 2. The wind hook significantly improves the stability of the overall structure, effectively resisting the invasion of strong winds and preventing the photovoltaic panel from being lifted or damaged. At the same time, the wind hook cleverly blocks part of the drainage groove, making it less noticeable and maintaining the cleanliness and aesthetics of the overall appearance.

[0009] 3. The equal pressure cavity helps balance the air pressure inside and outside the photovoltaic panel, reducing the structural stress caused by air pressure differences, thereby reducing the risk of component cracking and deformation, and prolonging the service life of the photovoltaic panel.

[0010] 4. In strong winds, especially when the wind direction is opposite to the water flow direction, wind force may push the water flow back into the drainage groove, causing poor drainage or even water accumulation. The hook can effectively block the water flow pushed by the wind force, preventing backflow.

[0011] 5. The hook not only plays a role in preventing backflow at the drainage groove, but also serves as part of the windproof component, enhancing the stability of the overall structure and preventing the photovoltaic panel from being lifted or damaged in strong winds.

[0012] 7. The wedge-shaped rubber strip forms a surface contact with the upper horizontal frame, reducing the pressure and ensuring uniform stress distribution on the photovoltaic tile horizontal frame, thereby ensuring higher overall safety.

[0013] Based on the above technical solutions, the photovoltaic tile structure with an equal pressure cavity can be further improved as follows:

[0014] Among them, the photovoltaic panel includes a first upper photovoltaic glass, a second upper photovoltaic glass, a first lower photovoltaic glass and a second lower photovoltaic glass, the photovoltaic panel is overlapped in the water flow direction, the first upper photovoltaic glass and the second upper photovoltaic glass are located on the same straight line, the first lower photovoltaic glass and the second lower photovoltaic glass are located on the same straight line, the first upper photovoltaic glass is parallel to the first lower photovoltaic glass, the second upper photovoltaic glass is parallel to the second lower photovoltaic glass, the intersection of the edges of the first upper photovoltaic glass, the second upper photovoltaic glass, the first lower photovoltaic glass and the second lower photovoltaic glass is fixedly connected with the frame by a sealing rubber strip.

The water flow direction allows rainwater to flow quickly down the surface of the photovoltaic panel, reducing water accumulation. The water flow direction allows rainwater to drain more quickly through the drainage groove, avoiding drainage groove blockage.

[0018] Further, a drainage groove is formed between the right frame and the left frame, and the drainage groove has a hollow rectangular structure.

[0019] Further, the upper horizontal frame is provided with an extended horizontal plate on the lower bottom surface, and the upper portion of the upper horizontal frame is provided with a letter L-shaped sliding groove.

[0020] Further, the windproof hook has a character F-shaped structure, and the end of the lower bottom surface of the windproof hook is fixedly connected with a character Z-shaped connecting plate, and the Z-shaped connecting plate is matched with the L-shaped sliding groove.

[0021] The improved scheme has the beneficial effects that: the character F-shaped structure has high rigidity and strength, can effectively resist the action of wind force and other external forces, and ensures the stability of the photovoltaic panel in strong wind weather. At the same time, the wind force and other external forces can be dispersed to a larger area, reducing local stress concentration and reducing the damage risk of the photovoltaic panel and the connecting parts. The character F-shaped structure can cover a larger area, effectively prevent rainwater from penetrating into the photovoltaic panel, and improve the waterproof performance.

[0022] The windproof hook is clamped and installed with the horizontal frame, which is convenient for installation and maintenance, reduces the installation time and cost.

[0023] Further, the upper end of the windproof hook is clamped above the first upper photovoltaic glass and the second upper photovoltaic glass, and the lower end of the windproof hook is clamped and connected with the upper horizontal frame and covers the right frame and the left frame in the upper group.

[0028] 2. The windproof hook significantly improves the stability of the overall structure, can effectively resist the invasion of strong wind, and prevents the photovoltaic plate from being lifted or damaged. At the same time, the windproof hook cleverly shields part of the drainage groove, so that it is not easy to be noticed, and the overall appearance is kept clean and beautiful.

[0029] 3. The equal-pressure cavity helps to balance the air pressure inside and outside the photovoltaic plate, reduces the structural stress caused by the difference in air pressure, thereby reducing the risk of component cracking and deformation, and prolonging the service life of the photovoltaic plate.

[0030] 4. In strong wind weather, especially when the wind direction is opposite to the water flow direction, the wind force may push the water flow back into the drainage groove, causing poor drainage or even water accumulation. The hook can effectively block the water flow pushed by the wind force to prevent backflow.

[0031] 5. The hook not only plays a role in preventing backflow at the drainage groove, but also can be part of the windproof component to enhance the stability of the overall structure and prevent the photovoltaic plate from being lifted or damaged in strong wind weather.
