[0028] Please refer to Figures 1-4 , this utility model provides a new technical solution: a photovoltaic flexible bracket, which includes a power conversion box 1, an N-shaped plate 2 is fixedly installed on the upper surface of the power conversion box 1, and a hollow column 7 is fixedly installed on the upper surface of the N-shaped plate 2;

[0029] Among them, an adjustment mechanism is provided on the N-shaped plate 2, and the adjustment mechanism includes a fixed rod 3, a first bevel gear 4, a second bevel gear 5, a threaded rod 6, a hollow column 7, a limiting groove 8, a sliding block 9, a limiting block 10, a rotating platform 11, a hydraulic device 12, a hydraulic rod 13, a fixed block 14, a damper 15, a spring 16, a piston rod 17, a photovoltaic power generation panel 18 and a knob 19.

[0030] Furthermore, the fixed rod 3 is rotatably sleeved on the inner surface of the vertical plate of the N-shaped plate 2, and the rear end of the fixed rod 3 penetrates through the rear surface of the N-shaped plate 2;

[0031] Among them, the knob 19 is fixedly installed at the rear end of the fixed rod 3.

[0032] Furthermore, the first bevel gear 4 is fixedly sleeved on the outer surface of the fixed rod 3, and the second bevel gear 5 is meshed and connected to the outer surface of the first bevel gear 4;

[0033] Among them, the threaded rod 6 is fixedly sleeved on the inner surface of the second bevel gear 5, and the lower end of the threaded rod 6 is rotatably connected to the upper surface of the power conversion box 1.

[0034] Furthermore, two limiting grooves 8 are respectively opened on the inner surface of the hollow column 7, the sliding block 9 is threadedly sleeved on the outer surface of the threaded rod 6, and the sliding block 9 is slidably sleeved on the inner surface of the hollow column 7;

[0035] Among them, two limit blocks 10 are both fixedly installed on the outer surface of the sliding block 9. The two limit blocks 10 are respectively slidably connected with the two limit grooves 8. The rotating platform 11 is fixedly installed on the upper surface of the sliding block 9.

[0036] Furthermore, the lower surface of the hydraulic actuator 12 is rotatably connected to the upper surface of the rotating platform 11. The hydraulic rod 13 is slidably sleeved on the inner surface of the hydraulic actuator 12. The fixed block 14 is rotatably connected to the upper end of the hydraulic rod 13.

[0037] Furthermore, the damper 15 is fixedly installed on the upper surface of the fixed block 14. The spring 16 is fixedly installed on the upper surface of the damper 15. The piston rod 17 is fixedly installed on the upper end of the spring 16, and the piston rod 17 is slidably sleeved on the inner surface of the damper 15;

[0038] Among them, the photovoltaic panel 18 is fixedly installed on the upper surface of the piston rod 17;

[0039] When this photovoltaic flexible bracket is in use, by rotating the knob 19, the knob 19 drives the fixed rod 3 fixedly installed on the front surface to rotate. The fixed rod 3 drives the first bevel gear 4 fixedly sleeved on the outer surface to rotate. The first bevel gear 4 drives the second bevel gear 5 meshed on the outer surface to rotate. The second bevel gear 5 drives the threaded rod 6 fixedly sleeved on the inner surface to rotate. At this time, the sliding block 9 threadedly sleeved on the outer surface of the threaded rod 6 slides upward in the inner wall of the hollow column 7 through the thread provided on the outer surface of the threaded rod 6. The two limit blocks 10 fixedly installed on the outer surface of the sliding block 9 limit the sliding block 9 with the two limit grooves 8 opened on the inner wall of the hollow column 7, preventing the sliding block from rotating by itself through the thread provided on the outer surface of the threaded rod 6, and limiting it so that it can only move up and down. At this time, by starting the hydraulic actuator 12, the hydraulic actuator 12 drives the hydraulic rod 13 slidably sleeved on the inner surface to move upward through operation. At the same time, the hydraulic rod 13 exerts an upward thrust on the fixed block 14 rotatably connected to the upper end. At this time, the fixed block 14 pushes the photovoltaic panel 18 to rotate on the upper surface of the rotating platform 11 to complete the angle adjustment. When the photovoltaic panel 18 moves backward under the influence of the environment, the photovoltaic panel 18 exerts a pressure on the piston rod 17 fixedly installed on the rear surface, causing it to slide downward on the inner surface of the damper 15. The damper in the present invention is a liquid damper, and its working principle is based on the principle of fluid mechanics, and the damping effect is achieved through the flow and pressure transmission of the damping oil in the closed container. And at the same time, the piston rod 17 exerts a pressure on the spring 16 fixedly installed on the lower surface, causing it to contract, and the elastic potential energy of the spring 16 itself is used to slow down the force of the photovoltaic panel 18 moving backward to form a buffer;

[0040] This photovoltaic flexible bracket drives the sliding block to move upward through a threaded rod, that is, drives the rotating platform and the photovoltaic power generation panel above the sliding block to move upward. At the same time, the hydraulic device can be used to drive the photovoltaic power generation panel to rotate on the rotating platform to complete the angle adjustment, maximizing the power generation efficiency of the photovoltaic power generation panel, further improving the energy utilization rate. Moreover, this photovoltaic flexible bracket can use springs, dampers and piston rods to slow down the irregular vibration with a large deformation amplitude generated by the photovoltaic power generation panel under the action of wind load, thereby protecting the photovoltaic power generation panel components and helping to improve the service life of the photovoltaic power generation panel components.

[0041] Working principle: When this photovoltaic flexible bracket is in use, by rotating the knob 19, the knob 19 drives the fixed rod 3 fixedly installed on the front surface to rotate. The fixed rod 3 drives the first bevel gear 4 fixedly sleeved on the outer surface to rotate. The first bevel gear 4 drives the second bevel gear 5 meshed on the outer surface to rotate. The second bevel gear 5 drives the threaded rod 6 fixedly sleeved on the inner surface to rotate. At this time, the sliding block 9 threadedly sleeved on the outer surface of the threaded rod 6 slides upward in the inner wall of the hollow column 7 through the thread provided on the outer surface of the threaded rod 6. Two limit blocks 10 fixedly installed on the outer surface of the sliding block 9 and two limit grooves 8 opened on the inner wall of the hollow column 7 limit the sliding block 9 to prevent the sliding block from rotating by itself through the thread provided on the outer surface of the threaded rod 6, and limit it so that it can only move up and down. At this time, by starting the hydraulic device 12, the hydraulic device 12 drives the hydraulic rod 13 slidably sleeved on the inner surface to move upward through operation. At the same time, the hydraulic rod 13 exerts an upward thrust on the fixed block 14 rotatably connected at the upper end. At this time, the fixed block 14 pushes the photovoltaic power generation panel 18 to rotate on the upper surface of the rotating platform 11 to complete the angle adjustment. When the photovoltaic power generation panel 18 moves backward under the influence of the environment, the photovoltaic power generation panel 18 exerts a pressure on the piston rod 17 fixedly installed on the rear surface, causing it to slide downward in the inner surface of the damper 15. The damper in the present invention is a liquid damper, and its working principle is based on the principle of fluid mechanics, and the damping effect is realized through the flow and pressure transmission of damping oil in a closed container. And at the same time, the piston rod 17 exerts a pressure on the spring 16 fixedly installed on the lower surface, causing it to contract, and the elastic potential energy of the spring 16 itself is used to slow down the force of the photovoltaic power generation panel 18 moving backward to form a buffer.

[0042] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
