It should be noted that these exemplary embodiments can be implemented in many different forms and should not be construed as being limited to the embodiments described herein.

[0034] like Figures 1 to 5 As shown, as the first aspect of the utility model, the photovoltaic tracking bracket includes a mounting base 4, a support column 1, a first telescopic movable member 2 and a second telescopic movable member 3. The support column 1 is rotatably arranged on the mounting base 4. The upper end of the support column 1 is rotatably connected with a first frame 11 and a second frame 12, and the first frame 11 and the second frame 12 are located on both sides of the support column 1. One end of the first telescopic movable member 2 is rotatably connected to the support column 1, and the other end is rotatably connected to the first frame 11, and the first telescopic movable member 2 is used to drive the first frame 11 to rotate at the end of the support column 1. One end of the second telescopic movable member 3 is rotatably connected to the support column 1, and the other end is rotatably connected to the second frame 12, and the second telescopic movable member 3 is used to drive the second frame 12 to rotate at the upper end of the support column 1. One end of the support column 1 away from the first frame 11 and the second frame 12 is rotatably arranged on the mounting base 4; wherein the first frame 11 and the second frame 12 are respectively and independently used to set photovoltaic components.

[0035] In this embodiment, the photovoltaic tracking bracket adjusts the two photovoltaic components to the optimal lighting angle through the adjustment of the first telescopic movable member 2 and the second telescopic movable member 3 according to the angle of sunlight, thereby improving the power generation efficiency of the photovoltaic components; in strong wind weather, the photovoltaic tracking bracket can make the two photovoltaic components in a horizontal state to reduce wind resistance, and at the same time rotate the supporting column 1 to change the angle of the two photovoltaic components, so that the length direction of the two photovoltaic components is consistent with the wind direction of the strong wind, further reducing wind resistance, so as to maintain stability even under the pressure of strong wind; in rainy days, through the driving of the first telescopic movable member 2 and the second telescopic movable member 3, the first frame 11 and the second frame 12 form an umbrella-like state on the supporting column 1, and rainwater can clean the dust on the surface of the photovoltaic component, and there is no water accumulation on the surface of the photovoltaic component, so that rainwater can quickly flow out from the surface of the photovoltaic component.

[0036] In an optional embodiment, a mounting plate 13 is sleeved on the support column 1. In the embodiment of the present application, the mounting plate 13 may be a rectangular plate-like structure, and the sliding direction of the mounting plate 13 is the length direction of the support column 1. One side of the mounting plate 13 is rotationally connected to an end of the first telescopic movable member 2 away from the first frame 11, and the other side of the mounting plate 13 is rotationally connected to an end of the second telescopic movable member 3 away from the second frame 12. The first telescopic movable member 2 and the second telescopic movable member 3 are relatively arranged on both sides of the mounting plate 13. Due to the positioning of the first telescopic movable member 2 and the second telescopic movable member 3 by the mounting plate 13, in the process of the first telescopic movable member 2 driving the first frame 11 and the second telescopic movable member 3 driving the second frame 12, the first frame 11 and the second frame 12 can be more stably rotated at the end of the support column 1, thereby more stably adjusting the angle of the photovoltaic module.

[0037] In an optional embodiment, the mounting plate 13 is slidably disposed on the support column 1, and the photovoltaic tracking bracket further comprises an adjustment component for driving the mounting plate 13 to reciprocate on the support column 1. A rotating carrier plate 41 is rotatably disposed on the mounting base 4, and the rotating carrier plate 41 may be a circular structure.

[0038] The adjustment assembly includes a first adjustment drive member 51 and a second adjustment drive member 52; one end of the first adjustment drive member 51 is arranged on the rotating carrier plate 41, and the other end is connected to the mounting plate 13; one end of the second adjustment drive member 52 is arranged on the rotating carrier plate 41, and the other end is connected to the mounting plate 13. The first adjustment drive member 51 and the second adjustment drive member 52 can synchronously drive the mounting plate 13 to reciprocate on the support column 1. The first adjustment drive member 51 is connected to one side of the mounting plate 13, and the second adjustment drive member 52 is connected to the other side of the mounting plate 13, which can realize stable driving of the mounting plate 13, thereby making the mounting plate 13 stably slide on the support column 1. The first adjustment drive member 51, the second adjustment drive member 52, the first telescopic movable member 2 and the second telescopic movable member 3 are not located on the same side of the mounting plate 13. The support column 1 can be a square column structure or a cylindrical structure. In the embodiment of the present application, the support column 1 can be a cylindrical structure. The support column 1 with a cylindrical structure is more convenient for the mounting plate 13 to reciprocate thereon. One end of the support column 1 away from the first frame 11 and the second frame 12 is arranged on the rotating carrier 41, and the support column 1 is located between the first adjustment drive member 51 and the second adjustment drive member 52. The arrangement of the rotating carrier 41 can drive the support column 1, the first adjustment drive member 51 and the second adjustment drive member 52 to rotate synchronously.

[0039] The mounting base 4 is also provided with a rotating motor 42, which is used to drive the rotating carrier plate 41 to rotate on the mounting base 4. The mounting base 4 is also integrally formed with a mounting ring 43, which is a ring-shaped structure, and the rotating carrier plate 41 is located in the mounting ring 43. An annular mounting groove is formed between the mounting ring 43 and the rotating carrier plate 41, and the rotating motor 42 is located in the mounting groove. In the embodiment of the present application, the mounting groove can be covered so that the rotating motor 42 is in a sealed environment to reduce the influence of dust and rain.

[0040] In this embodiment, in a sunny state, the first adjustment drive member 51 and the second adjustment drive member 52 drive the mounting plate 13 to slide on the support column 1 in a direction away from the mounting base 4, and at the same time, the first telescopic movable member 2 and the second telescopic movable member 3 extend to respectively drive the first frame 11 and the second frame 12 to be in a horizontal state, at which time, the first adjustment drive member 51 and the second adjustment drive member 52 stop driving. Then the rotary motor 42 drives the rotating carrier plate 41 to rotate, so that the first frame 11 and the second frame 12 rotate to the angle with the strongest sunlight, and then the first telescopic movable member 2 drives the first frame 11 to retract, so that the side of the first frame 11 away from the end of the support column 1 tilts downward. The second telescopic movable member 3 extends again, so that the side of the second frame 12 away from the end of the support column 1 tilts upward. Therefore, the photovoltaic components on the first frame 11 and the second frame 12 can be adjusted to a better sunlight exposure angle, which is conducive to absorbing light and improving efficiency.

[0041] In rainy days, the first frame 11 of the first telescopic movable member 2 tilts downward on the side away from the end of the supporting column 1, and the second telescopic movable member 3 drives the second frame 12 to tilt downward on the side away from the end of the supporting column 1, so that the angle between the first frame 11 and the second frame 12 and the supporting column 1 is less than 90°, forming an umbrella-like state, so that rainwater can wash dust on the surface of the photovoltaic module, and rainwater can quickly flow to the ground to reduce water accumulation.

[0042] In a strong wind state, the first telescopic movable member 2 and the second telescopic movable member 3 extend to respectively drive the first frame 11 and the second frame 12 to be in a horizontal state to reduce wind resistance; then the rotating motor 42 drives the rotating carrier plate 41 to rotate, so that the length direction of the first frame 11 and the second frame 12 is consistent with the wind direction of the strong wind, further reducing wind resistance and maintaining the photovoltaic module in a stable working state under strong winds, while also reducing the damage to the tracking bracket.

[0043] On a cloudy day, the first adjustment drive member 51 and the second adjustment drive member 52 drive the mounting plate 13 to slide on the supporting column 1 toward the mounting base 4, and then the first telescopic movable member 2 and the second telescopic movable member 3 respectively drive the first frame 11 and the second frame 12 to rotate toward the supporting column 1 until the first frame 11 and the second frame 12 are in a vertical state. At this time, the first frame 11 and the second frame 12 are consistent with the length direction of the supporting column 1, thereby reducing the adsorption of dust and impurities on the photovoltaic module, improving the power generation efficiency of the photovoltaic module, and extending the service life of the two photovoltaic modules.

[0044] In an optional embodiment, a support plate 14 is connected to the end of the mounting base 4. In the embodiment of the present application, the support plate 14 can be a rectangular plate-shaped structure. The first frame 11 is rotatably connected to the support plate 14 through a plurality of first hinges. The first hinge is composed of a first fixing member and a first hinge seat. The first fixing member is connected to the first frame 11, and the first hinge seat is connected to the support plate 14. The second frame 12 is rotatably connected to the support plate 14 through a second hinge. The second hinge is composed of a second fixing member and a second hinge seat. The second fixing member is connected to the second frame 12, and the second hinge seat is connected to the support plate 14. The provision of the first hinge and the second hinge realizes the rotatable connection between the first frame 11 and the second frame 12 and the support plate.

[0045] A multi-channel sensor 141 is provided in the middle of the support plate 14 for sensing light intensity, rainfall, wind direction and wind speed. A control unit is provided on the mounting base 4 for controlling the driving of the first adjustment drive member 51, the second adjustment drive member 52, the first telescopic movable member 2 and the second telescopic movable member 3. When the multi-channel sensor 141 senses the light intensity, rainfall, wind direction and wind speed, the control unit is activated again to drive the first adjustment drive member 51, the second adjustment drive member 52, the first telescopic movable member 2 and the second telescopic movable member 3 to work.

[0046] In an optional embodiment, the length of the support column 1 is greater than the length of the photovoltaic module. When the length of the support column 1 is greater than the length of the photovoltaic module, the first frame 11 and the second frame 12 can be in a vertical state.

[0047] In an optional embodiment, the first telescopic movable member 2, the second telescopic movable member 3, the first adjusting driving member 51 and the second adjusting driving member 52 are respectively and independently one of an electric cylinder, a pneumatic cylinder and an oil cylinder.

[0048] The first telescopic movable member 2, the second telescopic movable member 3, the first adjusting driving member 51 and the second adjusting driving member 52 in the embodiment of the present application can all be electric cylinders, which have higher precision and can further improve the use effect of the photovoltaic tracking bracket.
