Technical Field

[0001] The invention relates to the technical field of ground solar photovoltaic brackets, and in particular to an aluminum profile ground solar photovoltaic bracket. Background Art

[0002] Solar photovoltaic racks are structural components used to support and fix photovoltaic modules, while ground-mounted solar photovoltaic racks are structures specially designed for installing and fixing solar photovoltaic modules on the ground, usually used in large photovoltaic power plants and commercial projects.

[0003] For example, "An aluminum profile ground solar photovoltaic bracket" with publication number CN115032509B includes two aluminum profile bases and an installation box arranged in the middle position of the two aluminum profile bases. An adjustment mechanism is provided on the installation box, and the adjustment mechanism is assembled to adjust the distance between the two installation boxes. Concrete bases are cast at both ends of the aluminum profile base.

[0004] However, in the prior art, it is inconvenient to adjust the angle of the solar panel according to weather conditions during the use of the solar photovoltaic bracket. In strong winds, the excessive contact area will cause the solar panel to be easily blown over in strong winds. At the same time, the inability to adjust the angle will cause some rainwater to accumulate in the bracket in rainy weather, causing part of the structure to be immersed in water for a long time, and its aging and oxidation rates will be accelerated.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

One end of the movable rod 42 is rotatably connected to one end of the fixed rod 41, and the other end of the fixed rod 41 is fixedly connected to one end of the base 1. One end of the positioning bracket 43 is rotatably connected to one side of the fixed rod 41, one end of the connecting rod 44 is slidably connected to the movable rod 42, and the other end of the positioning bracket 43 is rotatably connected to the connecting rod 44. A mounting connecting plate 45 is fixedly installed on the upper surface of the positioning bracket 43, and the solar panel body 4 is fixedly installed on the upper surface of the mounting connecting plate 45.

[0021] In this embodiment, the solar panel body 4 is fixedly mounted on the upper surface of the mounting connecting plate 45. When deploying the device, the base 1 is fixed on the ground by pouring concrete to maintain the stability of the foundation. When receiving solar energy normally, the plurality of mounting connecting plates 45 are adjusted to an inclined state by the direction adjustment component 2. At this time, the mounting connecting plates 45 can be completely spliced ​​together to form an inclined surface, which can normally receive solar energy. In the event of special windy and rainy weather, the mounting connecting plates 45 can also be adjusted to a horizontal state by the direction adjustment component 2. During the rotation of the movable rod 42, the angle of the connecting rod 44 will be changed, and the change in the angle of the connecting rod 44 will simultaneously push the multiple positioning brackets 43 to change the angle of the mounting connecting plate 45. When the mounting connecting plate 45 is adjusted to a horizontal state, the contact angle between the solar panel body 4 and the strong wind will be close to a parallel state, and the overall contact area will become smaller than that in the inclined state, which can prevent the solar panel from being blown over due to excessive wind force.

The connecting roller 210 at the end of the support rod 29 is overlapped on the limit frame 25 on the lower surface of the push rod 22. Under the push of the support rod 29, the connecting roller 210 moves along the direction of the limit frame 25, and thereby changes the angle of the push rod 22, thereby achieving the purpose of pushing the movable rod 42. The existence of the connecting roller 210 can greatly reduce the friction force and play a role in accelerating the angle adjustment speed.

[0024] Embodiment 3: According to Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the direction adjustment component 2 includes a support frame 21 and a push rod 22. The support frame 21 is fixedly mounted on the upper surface of the base 1, and one end of the push rod 22 is rotatably mounted at a corner at the top of the support frame 21. A guide rod 23 is fixedly mounted on one side of the push rod 22, and a reinforcement rod 48 is slidably connected to the outer wall of the guide rod 23. A first positioning block 24 is fixedly mounted on one side of the support frame 21, and a worm 28 is rotatably mounted inside the first positioning block 24. The worm 28 is parallel to the horizontal ground. A second positioning block 26 is fixedly mounted on the upper surface of the support frame 21, and a worm wheel 27 is rotatably mounted on one side of the second positioning block 26.

The self-locking function of the worm wheel 27 and the worm 28 transmission can maintain the structural stability of the entire assembly; During the rotation of the push rod 22, the reinforcing rod 48 is pushed by the guide rod 23, thereby achieving the purpose of changing the angle of the movable rod 42, and the guide rod 23 can also determine the moving route of the reinforcing rod 48, ensuring that all structures can rotate within a fixed range.

[0026] The use method and working principle of the device: the solar panel body 4 is fixedly mounted on the upper surface of the mounting connecting plate 45. When receiving solar energy normally, multiple mounting connecting plates 45 are spliced ​​together to form an inclined surface, which can normally receive solar energy. In the event of special wind and rain weather, the mounting connecting plates 45 can also be adjusted to a horizontal state through the adjustment component 2; The worm gear 27 is pushed by rotating the worm 28, and the angle of the support rod 29 is changed by using the worm gear 27. The connecting roller 210 at the end of the support rod 29 overlaps the limit frame 25 on the lower surface of the push rod 22. Under the push of the support rod 29, the connecting roller 210 moves along the direction of the limit frame 25 to change the angle of the push rod 22. During the rotation of the push rod 22, the reinforcing rod 48 is pushed by the guide rod 23, so as to achieve the purpose of changing the angle of the movable rod 42. During the rotation of the movable rod 42, the extension rod 46 on its side moves along the strip hole 47 and synchronously pushes the connecting rod 44 to change the angle of the positioning bracket 43, thereby achieving the purpose of changing the angle of the installation connecting plate 45. When the installation connecting plate 45 is adjusted to a horizontal state, the contact angle between the solar panel body 4 and the strong wind will be close to a parallel state, and the overall contact area will become smaller than that in the inclined state, which can avoid the solar panel being blown over due to excessive wind force.
