[0002] At present, the country is vigorously promoting new energy, namely carbon neutrality and carbon compliance, energy conservation and emission reduction, and taking the path of sustainable development. It strongly encourages and requires the installation of photovoltaics in new industrial and commercial projects, and the proportion is increasing year by year.

[0003] Specification 55015-2021 "General Specification for Building Energy Conservation and Renewable Energy Utilization" clearly requires that the service life of roof photovoltaics should not be less than 25 years. In order to meet the 25-year photovoltaic roof, most roofs use TPO waterproof membranes, which are resistant to high temperatures and have a long service life. In order to extend the service life, the waterproof layer of the roof must not be damaged when installing photovoltaics, and the photovoltaic power generation time must be at least 25 years. To this end, a dedicated photovoltaic mounting base is required. The existing photovoltaic mounting base includes a support, a base, a plug, a fixed plate, a pressure plate, a sliding groove, a slider nut, a bolt, a groove, a convex strip and a rubber strip. The support is arranged inside the base, and plugs are provided at both ends of the base, and a pressure block is provided on the upper part of the base.

A number of grooves are provided on the lower surface of the fixed plate, and a number of convex strips are provided on the upper surface of the base. A groove is provided on the lower surface of the fixing plate, corresponding to the convex strip on the upper surface of the base. A rubber strip is provided on the lower part of the pressure plate, and the photovoltaic panel is placed between the rubber strip and the base. Its shortcomings are: (1) The base is installed on the waterproof membrane by hot air welding. Although it solves the waterproof problem, it only relies on hot air welding, resulting in an unstable installation position of the base. In case of severe weather such as strong winds and typhoons, the position of the base will be offset; (2) The base is fixed with a strip, which is heavy and has a high production cost; (3) The photovoltaic heat dissipation effect is poor; (4) The base is completely covered on the support, and it is not easy to find the installation position of the sliding nut.
