[0001] The utility model relates to the field of photovoltaic panel fixing devices, in particular to a detachable fixing tool for a flexible photovoltaic panel. Background Art

[0002] At present, the roofs of many old buildings are built with color steel tiles. In order to make full use of photovoltaic energy, take into account the load-bearing capacity of color steel tile roofs and eliminate safety hazards, flexible photovoltaic panels are usually installed on color steel tile roofs. Flexible photovoltaic panels have photovoltaic power generation functions and are lighter than conventional glass frame components, reducing the burden of equipment installation and transportation, while avoiding excessive load on the roof.

[0003] For example, CN216312997U discloses an installation structure of a color steel tile photovoltaic power station, which includes a photovoltaic unit, a mounting plate, color steel tiles and U-shaped purlins. The photovoltaic unit includes a semi-flexible photovoltaic panel, a snap-on short frame and a shock-absorbing rubber strip. The snap-on short frame is symmetrically arranged on a pair of sides of the semi-flexible photovoltaic panel, and the other pair of sides of the semi-flexible photovoltaic panel is symmetrically provided with wind-resistant purlins. The shock-absorbing rubber strips are arranged on the back of the semi-flexible photovoltaic panel. The opposite sides of the semi-flexible photovoltaic panel with the snap-on short frame are fixed to the mounting plate by pressure block bolts, and the other pair of sides of the semi-flexible photovoltaic panel are glued to the wind-resistant purlins. The mounting plate and wind-resistant purlins are bolted to the U-shaped purlins.

[0004] However, this type of flexible photovoltaic panel fixed on the color steel tile by bolts has a large area of ​​color steel tile roof with low load-bearing capacity. This method requires processing the roof, which will reduce the load-bearing capacity of the color steel tile. It is also inconvenient to disassemble after fixing, which is not conducive to the recycling of the flexible photovoltaic panel. Utility Model Content
