It should also be understood that terms defined in, for example, common dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and should not be interpreted in an idealized or highly formal sense, unless explicitly defined as such herein.

[0032] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0033] As mentioned in the background technology above, although the existing technology has achieved the rotation and flipping of photovoltaic panels to adapt to changes in the solar altitude and azimuth angles, the photovoltaic panels are placed outdoors and are easily affected by the environmental climate, especially in windy areas. Since the photovoltaic panels have a certain angle with the horizontal ground, in windy weather, the photovoltaic panels will be subject to a large wind load, which can easily damage the photovoltaic panels. Based on this, the inventors of this application provide a photovoltaic bracket in one or more embodiments, which achieves the adjustment of the angle of the photovoltaic panel through the first drive mechanism and the sliding connection between the slide rod and the second vertical pole; the photovoltaic panel can be adjusted to a horizontal state and lowered to a safe height through the first drive mechanism and the second drive mechanism, avoiding the problem of damage to the photovoltaic panel due to the wind load in windy weather. Thus, one or more problems in the existing technology are solved.

[0034] In response to the above-mentioned technical problems, the present invention provides a photovoltaic bracket, such as Figure 1 and Figure 2 The utility model shows that: a mounting frame, the mounting frame for mounting the photovoltaic panel includes an upper frame 1 and a lower frame 2, and the upper frame 1 and the lower frame 2 are arranged parallel to each other up and down; an adjusting mechanism, the adjusting mechanism includes a sliding rod 3, a first vertical rod 4, a second vertical rod 5, a first driving mechanism 6 and a second driving mechanism 7, one end of the sliding rod 3 is connected to the upper frame 1, and the other end is connected to the lower frame 2, the top of the first vertical rod 4 is connected to the side of the sliding rod 3 close to the upper frame 1, and the side of the sliding rod 3 close to the lower frame 2 is slidably connected to the top of the second vertical rod 5, the driving end of the first driving mechanism 6 is connected to the bottom end of the first vertical rod 4 to drive the first vertical rod 4 to move in the vertical direction and drive the sliding rod 3 to slide on the second vertical rod 5, thereby adjusting the angle of the photovoltaic panel, the driving end of the second driving mechanism 7 is connected to the bottom of the second vertical rod 5 to drive the second vertical rod 5 to move in the vertical direction, and under the joint action of the first driving mechanism 6, the overall height of the photovoltaic panel is adjusted.

[0035] Specifically, when the angle of the photovoltaic panel needs to be adjusted according to the solar altitude, the first drive mechanism 6 drives the first vertical pole 4 to move vertically, thereby driving one end of the slide bar 3 to move vertically and, at the same time, driving the other end of the slide bar 3 to slide on the top of the second vertical pole 5, thereby adjusting the angle of the photovoltaic panel installed on the mounting frame. When encountering strong winds, the first drive mechanism 6 drives the first vertical pole 4 downward, lowering the top of the first vertical pole 4 to the same height as the top of the second vertical pole 5, and the photovoltaic panel is in a horizontal position. The second drive mechanism 7 is then activated to drive the second vertical pole 5 downward. Under the combined action of the first drive mechanism 6 and the second drive mechanism 7, the height of the photovoltaic panel, which is in a horizontal position, can be lowered to a safe height, thereby reducing the effects of strong winds and the wind load on the photovoltaic panel. Furthermore, a wind speed monitor can be installed on the mounting frame. When the monitored wind speed reaches a certain value, the photovoltaic panel control system can issue a command to the first drive mechanism 6 and the second drive mechanism 7, instructing them to operate to lower the photovoltaic panel to a safe height. The photovoltaic panels can also be lowered to a safe height in advance based on the weather forecast.

[0036] Compared with the existing technology, the photovoltaic bracket of the present application realizes the adjustment of the angle of the photovoltaic panel through the first drive mechanism 6 and the sliding connection between the slide rod 3 and the second vertical pole 5; the photovoltaic panel can be adjusted to a horizontal state and lowered to a safe height through the first drive mechanism 6 and the second drive mechanism 7, avoiding the problem of damage to the photovoltaic panel due to wind load in windy weather.

[0037] In some embodiments, the first driving mechanism 6 includes a first air cylinder, and the driving function of the first driving mechanism 6 is realized by the first air cylinder.

[0038] In some embodiments, the second driving mechanism 7 includes a second air cylinder, and the driving function of the second driving mechanism 7 is realized by the second air cylinder.

[0039] In some embodiments, as Figure 1 As shown, the photovoltaic support further includes a diagonal brace 8. The bottom end of the diagonal brace 8 is pivotally connected to the bottom end of the first vertical pole 4, and the top end of the diagonal brace 8 is slidably connected to the slide bar 3 between the top end of the first vertical pole 4 and the top end of the second vertical pole 5. The diagonal brace 8 strengthens the support structure and ensures the safety of the photovoltaic panel. Specifically, the bottom end of the diagonal brace 8 is pivotally connected to the bottom end of the first vertical pole 4 via a pin.

The two adjustment mechanisms further enhance the stability and rationality of the photovoltaic support structure.

[0041] In some embodiments, as Figure 5 As shown, a T-shaped slot 9 is provided at the bottom of the slide bar 3 along its length, and a T-shaped protrusion 10 is provided at the top of the second vertical bar 5, which is rotatable thereon. The T-shaped protrusion 10 is arranged in the T-shaped slot 9 and allows the T-shaped slot 9 to slide on the T-shaped protrusion 10. When the first driving mechanism 6 drives the first vertical bar 4 to move up and down, it drives the T-shaped slot 9 to slide on the T-shaped protrusion 10. Specifically, two parallel vertical plates 12 are provided on the second vertical bar 5, and a first pin 13 is provided on the T-shaped protrusion 10. The two ends of the first pin 13 are respectively rotatably connected to the two vertical plates 12. The first pin 13 and the vertical plate 12 realize the rotational connection between the T-shaped protrusion 10 and the top of the second vertical bar 5 to adapt to the change of the angle of the slide bar 3.

[0042] In some embodiments, as Figure 6 As shown, a rotatable T-shaped slider 11 is connected to the top of the diagonal brace 8. The T-shaped slider 11 is slidably disposed within the T-shaped slot 9. The sliding movement of the T-shaped slider 11 within the T-shaped slot 9 establishes a sliding connection between the top of the diagonal brace 8 and the slide bar 3. Specifically, the top of the diagonal brace 8 is rotatably connected to the T-shaped slider 11 via a second pin 14 to accommodate changes in the angle between the diagonal brace 8 and the slide bar 3.
