Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaics, and in particular relates to a curved roof photovoltaic bracket installation system. Background Art

[0002] Photovoltaic power generation is a clean energy source. Building a rooftop photovoltaic power station can effectively reduce thermal power consumption. In most cases, the photovoltaic power generation time is basically consistent with the peak power consumption period of enterprises. Distributed photovoltaic power generation can better absorb photovoltaic power, enjoy preferential electricity prices, and save electricity bills for enterprises. Compared with concrete structure roofs, steel structure roofs have higher installation technology requirements for photovoltaic panels. Traditional color steel plate roofs are mostly straight slope roofs, and the guide rails are mostly fixed to the roof by clamps or self-tapping screws. The clamp installation method requires that the color steel plate itself has good strength and the corrugated steel plate structure is easy to fix furniture. For distributed photovoltaic projects with curved roofs and wavy corrugated roof panels, the clamp fixing installation method is difficult to anchor and is easy to fall off in areas with large wind loads. The installation method using self-tapping screws is prone to roof leakage. Utility Model Content

[0024] The curved roof 6 of the building is an existing structure, generally including a support frame, a plurality of purlins arranged on the support frame, and a roof color steel plate arranged on the plurality of purlins, and the roof color steel plate is in an arc shape. The guide rail assembly 1 is arranged on the roof color steel plate along the arc length direction of the roof color steel plate, and the flexible steel cable 4 passes through the inside of the guide rail assembly 1, and the flexible steel cable 4 is tensioned by the tensioning assembly 5 at both ends of the flexible steel cable 4, so that the flexible steel cable 4 abuts against the guide rail 11, so that the flexible steel cable 4 generates a downward force on the guide rail assembly 1 through the tensioning action of the flexible steel cable 4, and the guide rail assembly 1 is safely and reliably pressed on the curved roof 6. When the wind blows, the photovoltaic panel 2 and the guide rail assembly 1 are pulled upward under the action of separation. At this time, the flexible steel cable 4 is further tensioned by the upward force transmitted by the guide rail assembly 1, and is transmitted to the curved roof 6 through the tensioning assembly 5, so that it can well resist the invasion of wind and prevent the photovoltaic panel 2 from being blown away, making it difficult for the photovoltaic panel 2 to fall off, and the tensioning assembly 5 can be set on the support frame of the curved roof 6 without damaging the original roof color steel plate of the curved roof 6, which can effectively avoid the risk of roof leakage. Furthermore, if Figure 5 As shown, in actual use, a plurality of the photovoltaic support installation systems of the curved roof 6 of the present invention can be arranged at intervals on the curved roof 6 according to the area of ​​the curved roof 6 to obtain more photovoltaic power.

The two ends of the screw 52 are respectively rotatably arranged on the two fixed disks 51. The ratchet 53 is located between the two fixed disks 51 and fixed on the screw 52. The two fixed disks 51 are respectively provided with vertical slide grooves 511 at corresponding positions. The two ends of the pin 54 are respectively slidably arranged in the vertical slide grooves 511 on the two fixed disks 51. When the pin 54 moves downward in the vertical slide groove 511, it can be inserted into the tooth groove of the ratchet 53. The flexible steel cable 4 is connected to the screw 52. The fixing plate 51 is provided with a connecting plate 55, which is convenient for installing the fixing plate 51 on one end of the curved roof 6, such as installing the connecting plate 55 on one end of the supporting frame of the curved roof 6.

Each straight segment can be installed with a photovoltaic panel 2, so that the photovoltaic panel 2 can be more firmly fixed on the guide rail 11. The guide rail 11 is fixed on the curved roof 6 by the construction adhesive 7, which can assist the fixed connection between the guide rail 11 and the curved roof 6.
