Generally, in order to facilitate automatic drainage of collected rainwater, the drainage tank 2 is generally arranged vertically or obliquely and vertically so as to realize an automatic sliding effect along the drainage tank 2 by utilizing the self weight of the rainwater; meanwhile, considering that the installation beam 1 is generally installed at an inclined roof or the like and is generally disposed in a horizontal lateral direction (i.e., a cross beam), the drain tank 2 may be disposed in a form perpendicular to the installation beam 1, forming a transverse-vertical cross distribution with the installation beam 1 on the building roof. And, since the photovoltaic panel is generally rectangular, after the photovoltaic panel is stably supported and mounted by the plurality of supporting mechanisms 3, the long sides of the photovoltaic panel are generally kept parallel to the drainage grooves 2, and the drainage grooves 2 are specifically located in the lower region of the long side gap of two adjacent (lateral) photovoltaic panels, so that the drainage grooves 2 can collect rainwater falling from the gap.

In this way, the supporting and mounting of the photovoltaic panel on the mounting beam 1 is mainly realized by the plurality of supporting mechanisms 3, and the supporting mechanisms 3 are specifically arranged on the mounting beam 1, so that the load of the photovoltaic panel is transferred to the mounting beam 1 through the supporting mechanisms 3, and finally the load of the photovoltaic panel is born by the mounting beam 1, and the structural strength of the mounting beam 1 is high, so that the stable supporting of the photovoltaic panel can be smoothly realized; meanwhile, rainwater in gaps of adjacent photovoltaic panels is collected through the drainage grooves 2, the drainage function can be conveniently achieved, and the drainage grooves 2 are only used for collecting rainwater and no longer bear the load of the photovoltaic panels, so that the material consumption and the material requirement of the drainage grooves 2 can be reduced in the production and manufacturing stage, and the production cost is reduced.

The base 31 is mounted on the mounting beam 1, and is typically mounted on the top surface (or top end surface) of the mounting beam 1. The supporting plate 32 is disposed on the base 31, generally on the top surface of the base 31, and is mainly used for supporting and mounting the side edge of the photovoltaic panel, such as a C-shaped groove clamped on the side edge of the photovoltaic panel. So configured, the load of the photovoltaic panel can be applied to the support pallet 32 and transferred to the mounting beam 1 through the base 31.

In order to facilitate the connection between the drainage tank 2 and the support mechanism 3 while preventing the load of the photovoltaic panel from being transmitted to the drainage tank 2, in this embodiment, a notch 311 is provided on the top surface of the base 31 to divide the base 31 into two parts through the notch 311, and the drainage tank 2 is installed through the notch 311, so that the drainage tank 2 can be embedded in the notch 311.
