[0002] At present, due to the vigorous development of photovoltaic technology, photovoltaic technology and photovoltaic products are becoming more and more popular and applied in life. For example, a variety of photovoltaic bracket products have appeared on the market, which combine photovoltaic panels with common outdoor brackets such as awnings, pergolas, and carports, so that the products have both solar energy conversion and shielding functions.

[0003] Traditional photovoltaic panels are usually supported by brackets to ensure that they are in an inclined state so that they can drain water on rainy days and prevent rainwater from accumulating on the photovoltaic panels. However, in the rainy season in summer, the precipitation is much greater than usual, and the drainage capacity of traditional gutters is too small. Rainwater is easily accumulated on the roof. The accumulated water causes water to enter the solar photovoltaic modules and cause damage, and rainwater overflows the gutters and causes the roof to leak. Therefore, a new technical solution needs to be designed to solve this problem. Utility Model Content

The accumulated water causes water ingress and damage to the solar photovoltaic components, and rainwater overflows the drainage gutters to cause roof leaks.

[0010] Preferably, the outer dimension of the screw rod matches the inner dimension of the fixing hole, and the dimension of the nut is larger than the dimension of the fixing hole.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model combines a stepped inclined plate, an inverted U-shaped water retaining plate, a water inlet hole, a buffer water tank and a drain pipe. When it rains, since a plurality of inverted U-shaped water retaining plates are arranged on the stepped inclined plate, the inverted U-shaped water retaining plates can block the rainwater flowing down the surface of the photovoltaic panel in sections and discharge it into the buffer water tank through the water inlet hole, and then discharge it through the drain pipe.

Then the nut is screwed to press the pressure plate onto the adjacent photovoltaic panel. At the same time, the first sealing gasket increases the sealing of the connection between the photovoltaic panel and the support frame, and the second sealing gasket increases the sealing of the connection between the pressure plate and the photovoltaic panel, thereby avoiding the gaps between adjacent photovoltaic panels that are prone to water seepage and causing damage to the photovoltaic components.

At the same time, the buffer water tank 31 can cache the rushing rainwater, thereby avoiding poor drainage causing rainwater to accumulate on the roof, resulting in water ingress and damage to the solar photovoltaic components, and avoiding rainwater overflowing the drainage trough to cause roof leakage.
