Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic power generation devices, in particular to a flexible bracket and a photovoltaic power generation device. Background Art

[0002] With the growing global demand for renewable energy, photovoltaic power generation, as a representative of clean energy, has received widespread attention and application. Photovoltaic power generation can be installed on rooftops, on the ground, on water surfaces, or other suitable locations for power generation, supply, or energy storage. Photovoltaic power generation uses solar energy to directly convert light energy into electrical energy through the photovoltaic effect. It primarily consists of three main components: solar panels (modules), a controller, and an inverter. Its core component is a photovoltaic cell (usually made of silicon). When light shines on a photovoltaic cell, the light energy stimulates the movement of electrons, generating an electric current.

[0003] Because photovoltaic modules are typically placed outdoors, brackets are typically used to secure the position of photovoltaic panels during operation. These brackets are used to support and secure the structure of the photovoltaic solar panels, ensuring they are at the optimal angle and position to receive sunlight. However, traditional photovoltaic brackets typically utilize fixed steel structures, which are less flexible. Once the photovoltaic panels are installed and secured to the brackets, the orientation angle and height of the panels are fixed, making them difficult to change and resulting in an extremely low error tolerance. This fixed bracket structure presents numerous inconveniences in practical applications: On the one hand, because the angle of incidence of sunlight varies with the season, time of day, and geographic location, the fixed brackets cannot be flexibly adjusted to change the orientation angle and height of the photovoltaic panels mounted thereon, thereby limiting the power generation efficiency of the photovoltaic power generation system under different conditions. On the other hand, for applications where the angle and height of the photovoltaic panels need to be frequently adjusted to adapt to special environments or for maintenance operations, traditional fixed brackets are particularly inconvenient, increasing the difficulty and cost of human operation.

[0004] In summary, existing photovoltaic brackets do not allow for secondary height and angle adjustments of the photovoltaic panels mounted on them to adapt to changes in sunlight and meet the needs of different application scenarios, resulting in numerous limitations and deficiencies. Therefore, a bracket structure that overcomes the shortcomings of traditional fixed photovoltaic brackets and offers a high degree of adjustability and flexibility is proposed. Utility Model Content

DETAILED DESCRIPTION

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods, but the present invention is not limited to the following embodiments.

[0025] Example 1:

[0026] See attached Figures 1 to 5 A flexible bracket includes a support leg 1 and an adjustment device. The support leg 1 is provided with an adjustment device, and a photovoltaic panel 6 can be fixed on the adjustment device. The adjustment device can then adjust the inclination angle of the photovoltaic panel 6 in the width direction and the inclination angle of the photovoltaic panel 6 in the length direction respectively, thereby adjusting the angle of the photovoltaic panel 6 fixed on the bracket. With the flexible bracket of the utility model, the staff can adjust the angle of the photovoltaic panel 6 fixed on the bracket by the flexible bracket according to actual needs to adapt to the changes in sunlight and meet the needs of different application scenarios. It has a simple structure and is highly adjustable and flexible.

[0027] Specifically, the adjustment device includes a first adjustment mechanism 2 and a second adjustment mechanism 3. The first adjustment mechanism 2 can adjust the tilt angle of the photovoltaic panel 6 fixed on the bracket in the width direction, and the second adjustment mechanism 3 can adjust the tilt angle of the photovoltaic panel 6 fixed on the bracket in the length direction.

[0028] Specifically, the first adjustment mechanism 2 includes a rotating shaft 21 and a driving assembly 22. A first connecting block 11 is provided at the bottom of each of the two supporting legs 1. The rotating shaft 21 is arranged between the two supporting legs 1, and its two ends are rotatably connected to the two first connecting blocks 11. One end of the rotating shaft 21 passes through the corresponding first connecting block 11 and is connected to the driving assembly 22. The driving assembly 22 is used to drive the rotating shaft 21 to rotate. A second connecting block 211 is provided on the rotating shaft 21. Figure 1 As described above, two second connecting blocks 211 can be set, and the photovoltaic panel 6 can be fixed on the second connecting blocks 211. When the driving component 22 drives the rotating shaft 21 to rotate, the photovoltaic panel 6 is driven to rotate in the width direction through the second connecting block 211, thereby adjusting the inclination angle of the photovoltaic panel 6 in the width direction.

[0029] Specifically, the drive assembly 22 includes a worm gear 221, a worm 222, and a motor 223. One end of the rotating shaft 21 passes through the corresponding first connecting block 11, on which a worm gear 221 is provided. A worm 222 is provided below the worm gear 221 and meshes with the worm 222. A first housing 224 is provided on the side of the first connecting block 11 facing the worm gear 221 and worm 222. The first housing 224 encases the worm gear 221 and worm 222 to protect them. One end of the worm 222 passes through a side wall of the first housing 224 and is connected to the output end of the motor 223. The motor 223 is fixed to the corresponding outer wall of the first housing 224. When the inclination angle of the photovoltaic panel 6 in the width direction of the photovoltaic panel 6 needs to be adjusted, the motor 223 is started, the worm 222 drives the worm gear 221 to rotate, and the rotating shaft 21 rotates accordingly, and drives the photovoltaic panel 6 to rotate in the width direction through the second connecting block 211.

[0030] Specifically, the side of the first housing 224 facing the motor 223 is hingedly connected to a second housing 225 via a connecting assembly 23. The second housing 225 encases the motor 223 to provide protection. The second housing 225 can be opened or closed relative to the first housing 224 via the connecting assembly 23, thereby facilitating regular maintenance of the motor 223. A heat dissipation net 226 is provided on one side of the second housing 225 to prevent the first and second housings 224, 225, from overheating.

[0031] Specifically, the connecting assembly 23 includes a fixed block 231, a slider 232, a rotating block 233, and a U-shaped limit block 234. The fixed block 231 is fixed to the side of the first housing 224 adjacent to the motor 223. The fixed block 231 is a hollow structure with a slide rail formed inside, and one end passes through one end of the fixed block 231. The slider 232 passes through the fixed block 231 and is inserted into the fixed block 231. The slider 232 can slide within the slide rail. A locking member 235 is provided between the slider 232 and the fixed block 231. Multiple locking holes can be provided on the slider 232, and corresponding locking holes are also provided on the corresponding side walls of the first housing 224. The locking member 235 passes through the locking holes on the side walls of the first housing 224 and on the slider 232 to lock the relative position of the slider 232 on the fixed block 231. It should be understood that the fixed block 231 and the slider 232 can also be connected by an interference fit to adjust the position of the slider 232 relative to the fixed block 231. A rotating block 233 is hingedly connected to the other end of the slider 232. The rotating block 233 is fixed to the side wall of the corresponding second housing 225. The rotating block 233 can rotate relative to the slider 232 about the connecting axis, thereby driving the second housing 225 to rotate and exposing the motor 223. A U-shaped limit block 234 is also provided at the connection between the rotating block 233 and the slider 232. The two ends of the U-shaped limit block 234 are fixed to the first housing 224, thereby limiting the rotation angle of the rotating block 233 and ensuring that the second housing 225 rests on the first housing 224 when not open. When the second housing 225 needs to be opened to a large angle relative to the first housing 224, the second housing 225 can be opened by sliding the slider 232 outward and then rotating the rotating block 233.

[0032] Specifically, the second adjustment mechanism 3 includes a U-shaped connector 31 and a telescopic rod 32. The interior of the support leg 1 is hollow and is equipped with the telescopic rod 32. The telescopic rod 32 can be extended and shortened relative to the support leg 1. The telescopic rod 32 can be an electric telescopic rod 32. The U-shaped connector 31 is fixed to the top of the telescopic rod 32. The first connecting block 11 is located in the groove of the U-shaped connector 31, and the side wall is hinged to the inner side wall corresponding to the U-shaped connector 31. The first connecting block 11 can rotate relative to the U-shaped connector 31. When the telescopic rod 32 on one support leg 1 is extended and the telescopic rod 32 on the other support leg 1 is stationary, the end of the rotating shaft 21 corresponding to the extended telescopic rod 32 is raised. The rotating shaft 21 rotates about the connection between the first connecting block 11 and the stationary telescopic rod 32, thereby driving the photovoltaic panel 6 fixed to the second connecting block 211 to rotate in the longitudinal direction, thereby adjusting the tilt angle of the photovoltaic panel 6 in the width direction. It is understood that as long as the telescopic rods 32 at both ends are extended to different lengths, they can both drive the photovoltaic panel 6 fixed to the second connecting block 211 to rotate in the longitudinal direction. At the same time, the height of the photovoltaic panel 6 fixed to the second connecting block 211 relative to the bottom surface can be adjusted by extending and shortening the telescopic rods 32.

[0033] Specifically, a base 4 is provided at the bottom of the supporting leg 1 , and a reinforcing rod 5 is provided between the two supporting legs 1 to improve the stability of the entire flexible bracket.

[0034] Example 2:

[0035] See attached Figure 4 and attached Figure 5 A photovoltaic power generation device includes a photovoltaic panel 6 and a flexible bracket according to Example 1. The photovoltaic panel 6 is fixed to the top of the second connecting block 211 of the flexible bracket. When the inclination angle of the photovoltaic panel 6 in the width direction of the photovoltaic panel 6 needs to be adjusted, the motor 223 is started, and the worm gear 221 and the worm 222 drive the rotating shaft 21 to rotate. The photovoltaic panel 6 rotates in the width direction of the photovoltaic panel 6 along with the rotating shaft 21, thereby adjusting the inclination angle of the photovoltaic panel 6 in the width direction of the photovoltaic panel 6. When the inclination angle of the photovoltaic panel 6 in the length direction of the photovoltaic panel 6 needs to be adjusted, the inclination angle of the photovoltaic panel 6 in the length direction of the photovoltaic panel 6 is adjusted by driving the telescopic rods 32 so that the two telescopic rods 32 extend to different lengths. In addition, the height of the photovoltaic panel 6 can also be adjusted by the extended lengths of the two telescopic rods 32. A heat insulation board 7 can also be provided at the bottom of the photovoltaic panel 6. The heat insulation board 7 is fixed to the top of the second connecting block 211 of the flexible bracket, and the photovoltaic panel 6 is fixed to the heat insulation board 7. The heat insulation board 7 can effectively prevent the heat generated by the photovoltaic panel 6 during the power generation process from being transferred to the second connecting block 211, thereby extending the service life of the flexible bracket. The utility model provides a flexible bracket and photovoltaic power generation device. Workers can perform secondary height and angle adjustments on the photovoltaic panels fixed on the bracket through the adjustment device of the flexible bracket according to actual needs, so as to adapt to changes in sunlight and meet the needs of different application scenarios. The utility model has a simple structure and is highly adjustable and flexible, which not only helps to improve the power generation efficiency of the photovoltaic power generation system, but also reduces the difficulty and cost of personnel operation, and promotes the application of photovoltaic power generation technology.
