[0034] like Figure 1 and Figure 2As shown, the embodiment of the utility model provides a concrete roof photovoltaic bracket for supporting and installing a photovoltaic panel 2, including a fixed rail 1, a pair of fixed rails 1 are arranged side by side, and two support rods 3 are arranged on each of the pair of fixed rails 1. The top of the support rod 3 is hinged with a mounting plate 4 for connecting the photovoltaic panel 2, and a driving mechanism 7 for driving the bottom ends of the two support rods 3 to move closer to each other is arranged on the fixed rail 1. Through this structural method, a pair of fixed rails 1 are fixed on the concrete roof, and two sets of driving mechanisms 7 are used to synchronously drive the two pairs of support rods 3 to rotate synchronously. When in the vertical state, the photovoltaic panel 2 can be lifted and supported to support and fix the photovoltaic panel 2. When the two pairs of support rods 3 are synchronously driven toward the horizontal by two sets of driving mechanisms 7, the photovoltaic panel 2 can be driven to move down close to the fixed rail 1. At this time, the photovoltaic panel 2 is close to the concrete roof, which can effectively reduce the tension of the wind on the photovoltaic panel 2 in windy weather, and avoid the phenomenon that the wind tension at the bottom of the photovoltaic panel 2 is too large and causes damage to the photovoltaic panel 2; a mounting ear block 12 is fixed to the bottom of the outer wall of the fixed rail 1, and a mounting hole 13 is opened on the mounting ear block 12 for installing and fixing the fixed rail 1.

[0035] like Figures 1 to 3 As shown, the driving mechanism 7 includes a rail groove 10 provided on the fixed rail 1, a bidirectional screw rod 15 rotatably installed in the rail groove 10, a pair of slide seats 14 slidably embedded in the rail groove 10, and a driving motor 11 installed at the end of the fixed rail 1 for driving the bidirectional screw rod 15 to rotate. The bottom ends of the two support rods 3 are respectively hinged with a pair of slide seats 14, and the pair of slide seats 14 are symmetrically threadedly sleeved with the bidirectional screw rod 15. By starting the driving motor 11 to drive the bidirectional screw rod 15 to rotate, the pair of slide seats 14 can be driven to move closer to or away from each other, which is used to lift the photovoltaic panel 2 through the support rod 3 or drive the photovoltaic panel 2 to move downward. A baffle 8 is fixed between the ends of the pair of fixed rails 1, and a rubber pillow strip 9 is arranged on the top of the baffle 8. After the photovoltaic panel 2 moves down close to the concrete roof, the photovoltaic panel 2 abuts on the rubber pillow strip 9 on the top of the baffle 8, and can cooperate with the fixed rail 1 to seal the bottom of the photovoltaic panel 2.

[0036] like Figures 1 to 5As shown, the two pairs of mounting plates 4 corresponding to the pair of fixed rails 1 are respectively provided with a first connecting member 5 and a second connecting member 6, the first connecting member 5 is used for the hinged installation of the mounting plate 4 and the photovoltaic panel 2, and the second connecting member 6 is used for the hinged sliding installation of the mounting plate 4 and the photovoltaic panel 2. Specifically, a connecting seat 16 is fixed on the top of the two pairs of mounting plates 4, the first connecting member 5 includes a first connecting block 17 hinged on the connecting seat 16, the hinge axis direction of the first connecting block 17 and the connecting seat 16 is perpendicular to the hinge axis direction of the support rod 3 and the mounting plate 4, a connecting ear plate 18 is provided on the first connecting block 17, and a first connecting hole 19 is opened on the connecting ear plate 18, the second connecting member 6 includes a second connecting block 20 hinged on the connecting seat 16, the hinge axis direction of the second connecting block 20 and the connecting seat 16 is perpendicular to the hinge axis direction of the mounting plate 4 and the support rod 3 The hinge axis direction of the rod 3 is vertically distributed; the second connecting member 6 also includes a connecting top plate 21 slidably connected to the top of the second connecting block 20, and a second connecting hole 22 is opened on the connecting top plate 21; the connecting top plate 21 is vertically distributed to the hinge axis direction of the second connecting block 20, and fixed blocks 23 are vertically fixed at both ends of the bottom of the connecting top plate 21, and two sliding rods 24 are fixedly connected between a pair of fixed blocks 23, and the two sliding rods 24 are movable through the second connecting block 20. Through this structural method, a pair of first connecting blocks 17 and a pair of connecting top plates 21 are respectively connected to the two sides of the bottom of the photovoltaic panel 2. When one of the two-way screw rods 15 is started alone, the corresponding side of the photovoltaic panel 2 can be driven to rise and fall, thereby adjusting the angle of the photovoltaic panel 2, so that the photovoltaic panel 2 can obtain better lighting effects according to the installation environment and improve the efficiency of solar energy utilization.

[0037] The working principle of the technical solution provided by the utility model is as follows:

[0038] When in use, a pair of fixed rails 1 are fixed on the concrete roof, and a pair of first connecting blocks 17 and a pair of connecting top plates 21 are respectively connected to the two sides of the bottom of the photovoltaic panel 2 using bolts. As a result, when a pair of driving motors 11 are started synchronously and the two bidirectional screw rods 15 are driven to rotate synchronously, the slide seats 14 on the fixed rails 1 are driven to move away from each other. At this time, the two pairs of support rods 3 rotate synchronously toward a vertical state, and the photovoltaic panel 2 can be lifted and supported for supporting and fixing the photovoltaic panel 2. When a pair of driving motors 11 are started in reverse, the pair of slide seats 14 on the fixed rails 1 slide close to each other, and the two pairs of support rods 3 tend to be horizontal, driving the photovoltaic panel 2 to move down and close to the fixed rails 1. The two ends of the photovoltaic panel 2 rest on the rubber pillow strips 9 at the top of the baffle 8. At this time, the photovoltaic panel 2 is close to the concrete roof, which can effectively reduce the tension generated by the wind on the photovoltaic panel 2 in windy weather, and avoid the phenomenon that the wind tension at the bottom of the photovoltaic panel 2 is too large and causes damage to the photovoltaic panel 2. Furthermore, by utilizing the hinged connection between the second connecting block 20 and the first connecting block 17 and the connecting seat 16 at the top of the two pairs of mounting plates 4, and the sliding cooperation between the connecting top plate 21 and the second connecting block 20, when one of the bidirectional screw rods 15 is started alone, the corresponding side of the photovoltaic panel 2 can be driven to rise and fall, thereby adjusting the angle of the photovoltaic panel 2, so that the photovoltaic panel 2 can obtain better lighting effects according to the installation environment, thereby improving the efficiency of solar energy utilization.

In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
