Abstract

Its basic structural layers, from bottom to top, are: structural layer, leveling layer, bonding layer, waterproof layer, and protective layer. Traditional rooftop photovoltaic (PV) brackets often use a through-type fixing method, requiring drilling holes in the roof to install bolts, which can easily damage the waterproof layer and lead to leakage risks. While existing counterweight brackets avoid drilling, they suffer from low friction coefficients between the concrete base and the roof, making them prone to slippage under extreme wind loads. Furthermore, their adjustment capabilities are limited, making it difficult to match PV modules with different tilt angles and heights, and they lack effective windproof structures, failing to meet the needs of high wind pressure areas.

Detailed Implementation
[0017] The present invention will be further described below with reference to the accompanying drawings.
[0018] Example 1: Please refer to Figures 1-4. This utility model provides a technical solution: a flexible roof counterweight photovoltaic bracket, including a first fixed seat 1 and a second fixed seat 2. The first fixed seat 1 and the second fixed seat 2 are arranged at equal intervals on the top of the roof, specifically at intervals of 1.2-1.8m. A support rod 3 is fixedly connected inside the first fixed seat 1, and an adjustable support rod 4 is fixedly connected inside the second fixed seat 2. A fixed seat 5 is fixedly connected to the top of both the support rod 3 and the adjustable support rod 4. A connecting seat 6 is provided inside the fixed seat 5, and a fixing bolt 7 is provided between the connecting seat 6 and the fixed seat 5. The fixing bolt 7 fixes the rotation angle of the connecting seat 6. The inner wall of the fixed seat 5 is provided with a toothed groove, and the two sides of the connecting seat 6 are provided with protrusions. Under the tightening of the fixing bolt 7, the two sides of the fixed seat 5 are tightly attached to the two sides of the connecting seat 6, so that the toothed groove and the protrusion are engaged together, thereby fixing the rotation angle of the connecting seat 6. Since the rotation angle of the connecting seat 6 is adjustable, different tilt angles of the photovoltaic panels can be installed.
[0019] A crossbar 8 is provided on one side of the connecting seat 6 corresponding to the first fixed seat 1 and on one side of the connecting seat 6 corresponding to the second fixed seat 2. T-slots 9 are provided on both sides of the crossbar 8. A connector 10 is provided in the T-slot 9 near the connecting seat 6. The crossbar 8 is fixedly connected to the connecting seat 6 through the connector 10. The connector 10 includes a T-shaped rod, which is set in the T-slot 9. One end of the T-shaped rod passes through the mounting hole on the surface of the connecting seat 6, and a nut is provided at one end of the T-shaped rod. The crossbar 8 is fixed by tightening the nut.
[0020] Rubber pads 11 are fixedly connected to the bottom of the first fixing seat 1 and the second fixing seat 2. The rubber pads distribute the load, prevent excessive local pressure from damaging the waterproof layer, and also increase the friction between the fixing seat 1 and the roof, thus improving the wind resistance. The first fixing seat 1 and the second fixing seat 2 are hollow shells, and the interior of the first fixing seat 1 and the second fixing seat 2 is filled with concrete 12. The concrete 12 can be pre-filled in the shell or poured on the construction site in advance to ensure that the weight of a single first fixing seat 1 or second fixing seat 2 reaches 60-120kg.
[0021] A stabilizing plate 13 is fixedly connected to the bottom of the support rod 3 and the adjusting support rod 4. The stabilizing plate 13 contacts the bottom of the inner wall of the housing, which improves the stability of the support rod 3 and the adjusting support rod 4. The adjusting support rod 4 adopts the existing telescopic fixing rod. By adjusting the length of the support rod 4, it can adapt to different installation angles of the photovoltaic panel.
[0022] Mounting bases 14 are fixedly connected to the first fixing base 1 and the second fixing base 2 around their perimeter. Fixing rings 15 are fixedly connected to the surface of the mounting bases 14. First steel cables 16 are provided between two adjacent first fixing bases 1 and between two adjacent first fixing bases 1. Second steel cables 17 are provided between one side of the first fixing base 1 and the corresponding second fixing base 2. The system also includes a wall 18 fixed to the flexible roof. A third steel cable 19 connected to the wall 18 is provided on the side of the first fixing base 1 and the second fixing base 2 near the wall 18. Expansion bolts are provided inside the wall 18. One end of the third steel cable 19 is fixed to one end of the expansion bolt. The pre-tension of the steel cable is set at 2.5-3.5kN, so that the fixing bases form a whole and improve the overall wind resistance.
[0023] A photovoltaic panel 20 is provided on the surface of the crossbar 8. A fixing component 21 is provided between the photovoltaic panel 20 and the T-slot 9 of the crossbar 8. The fixing component 21 includes a pressure plate 211. A screw 212 is provided in the middle of the pressure plate 211. A fixing piece 213 is threaded to one end of the screw 212. During installation, the fixing piece 213 is placed into the T-slot 9, and the fixing piece 213 presses against the surface of the photovoltaic panel. The screw 212 is threaded to the fixing piece 213, thereby fixing the photovoltaic panel using the pressure plate 211.
