[0028] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0029] In some embodiments, please refer to the accompanying drawings. Figures 1-4 A heavy-duty photovoltaic frame includes a fixed frame 1, an auxiliary installation mechanism 2, a multi-angle self-locking adjustment mechanism 3, and a photovoltaic mounting frame 4. The auxiliary installation mechanism 2 for assisting in the installation of heavy photovoltaic panels is symmetrically installed on the front and rear sides of the right end of the fixed frame 1. The auxiliary installation mechanism 2 includes a movable component for facilitating the installation of photovoltaic panels and a support component for restricting the movable component. The movable component is installed on the front and rear sides of the right end of the fixed frame 1, and the support component is connected to the movable component.

[0030] The movable component is in a folded and retracted state when the photovoltaic panel is not being installed, and unfolds when the photovoltaic panel needs to be installed by pulling down the movable component.

[0031] The left end of the fixed frame 1 is symmetrically equipped with multi-angle self-locking adjustment mechanisms 3 for adjusting the angle of the photovoltaic mounting frame 4, facilitating the installation of photovoltaic panels and controlling the installation angle of the photovoltaic panels; the multi-angle self-locking adjustment mechanism 3 includes a rotating component, a multi-stage adjustment component and a locking component. The rotating component is provided on the left end of the fixed frame 1, and the multi-stage adjustment component and the locking component are installed on the rotating component; the rotating component is connected to the lower left side of the photovoltaic mounting frame 4, and the lower right side of the photovoltaic mounting frame 4 is hinged to the fixed frame 1;

[0032] In this invention, the movable component is pulled down to unfold, and then the photovoltaic mounting frame 4 is moved by pulling the component. Under the action of the limiting component, the photovoltaic mounting frame 4 is made to be horizontal. At this time, the photovoltaic panel can be pushed from the right end of the fixed frame 1 onto the photovoltaic mounting frame 4 through the movable component, and then the photovoltaic panel can be fixed on the photovoltaic mounting frame 4. After installation, the photovoltaic mounting frame 4 is rotated upward by the multi-stage adjustment component, and the locking component realizes multi-angle self-locking control of the photovoltaic mounting frame 4. Through the cooperation of the rotation component, the multi-stage adjustment component and the locking component, the device can flexibly adjust the installation angle of the photovoltaic panel, improve the installation efficiency of the photovoltaic panel, and improve the practicality of the device. Furthermore, through the cooperation of the movable component and the support component, it is convenient for operators to install heavy photovoltaic panels onto the photovoltaic mounting frame 4, reducing the probability of the photovoltaic panel tipping over during installation, and further improving the practicality of the device.

[0033] like Figure 1 and Figure 2 As shown, the movable component includes a first connecting rod 21, a second connecting rod 22, a support rod 23, and a sliding component for assisting the movement of the photovoltaic panel. The first connecting rod 21 is symmetrically hinged to the front and rear sides above the right end of the fixed frame 1, and the second connecting rod 22 is symmetrically hinged to the front and rear sides below the right end of the fixed frame 1. The outer ends of the first connecting rod 21 and the second connecting rod 22 are hinged to the support rod 23. The sliding component is installed in the middle of the support rod 23. The support component is installed on the first connecting rod 21 and the second connecting rod 22.

[0034] The sliding component may be a support guide wheel 24, and the support guide wheel 24 is rotatably mounted in the middle of the support rod 23.

[0035] like Figure 1 and Figure 2 As shown, the support assembly includes a support foot 25, a locking plate 26, and a limiting rod 28. The support foot 25 is fixedly installed at the lower end of the support rod 23. Two locking plates 26 are rotatably installed at the outer end of the support rod 23, and the locking plates 26 are provided with locking arc grooves 27 that cooperate with the limiting rods 28. The limiting rods 28 are symmetrically fixedly installed on the upper and lower sides of the right end of the fixing frame 1. The locking arc grooves 27 are engaged with the limiting rods 28.

[0036] In this invention, when the photovoltaic panel is not installed, the locking arc groove 27 is engaged with the limiting rod 28, and both the first connecting rod 21 and the second connecting rod 22 are tilted upwards and folded in retracted state, while the support rod 23 is in a vertical state. When the photovoltaic panel needs to be installed, the photovoltaic mounting frame 4 is first placed in a horizontal state, and then the locking plate 26 on the fixing frame 1 is rotated outwards to separate the locking arc groove 27 from the limiting rod 28. Then, the support rod 23 is pulled downwards, and the support rod 23 drives the first connecting rod 21 and the second connecting rod 22 to rotate downwards until the lower end of the support foot 25 contacts the ground. At this time, the first connecting rod 21 and the second connecting rod 22 are in a horizontally extended state, while the support rod 23 remains in a vertical state. The upper end of the support guide wheel 24 on the support rod 23 corresponds to the lower end of the photovoltaic mounting frame 4, and then the photovoltaic panel can be pushed onto the photovoltaic mounting frame 4 for installation via the support guide wheel 24.

[0037] like Figure 3 and Figure 4 As shown, the rotating assembly includes a rotating rod 31 and a sliding rod 32. The lower end of the rotating rod 31 is hinged to the fixed frame 1. A sliding groove 33 is provided on the rotating rod 31. The sliding rod 32 is slidably connected to the sliding groove 33 and the upper end of the sliding groove 33 is hinged to the lower left side of the photovoltaic mounting frame 4. The rotating rod 31 and the sliding rod 32 are connected to a multi-stage adjustment assembly and a locking assembly.

[0038] like Figure 3 and Figure 4 As shown, the multi-stage adjustment assembly includes ratchet 35, cam 36 and locking rod 37. A limit groove 34 is provided on the sliding rod 32. Multiple ratchet 35 are fixedly installed in the limit groove 34. The ratchet 35 are linearly and evenly distributed in the limit groove 34. A cam 36 is rotatably installed in the middle of the opposite end of the front and rear rotating rods 31. A locking rod 37 is fixedly installed above the cam 36. The locking rod 37 engages with the ratchet 35.

[0039] A torsion spring is wound around the connecting shaft between the cam 36 and the rotating rod 31, and one end of the torsion spring is fixedly connected to the cam 36, and the other end of the torsion spring is fixedly connected to the rotating rod 31, so that the locking rod 37 on the cam 36 is always located between the two ratchet teeth 35.

[0040] The upper end of the ratchet 35 is provided with an arc surface;

[0041] like Figure 3 and Figure 4 As shown, the locking assembly includes a locking plate 310, a locking groove 38 is provided at the upper end of the sliding rod 32, an unlocking groove 39 is provided at the lower end of the sliding rod 32, and the locking plates 310 are symmetrically fixedly installed at the ends of the two rotating rods 31 that are far apart from each other, and the cam 36 is provided with an avoidance groove 311 and a slot 312.

[0042] The lower end of the unlocking groove 39 is provided with an arc surface, and the arc surface at the lower end of the unlocking groove 39 is higher than the arc surface at the upper end of the ratchet 35.

[0043] The arc surface at the upper end of the ratchet 35 and the arc surface at the lower end of the unlocking groove 39 both face upwards;

[0044] The upper end of the locking groove 38 is also provided with an arc surface, and the arc surface provided on the locking groove 38 faces downward.

[0045] In this utility model, when photovoltaic panels need to be installed, the photovoltaic mounting bracket 4 is pulled upward. At this time, the photovoltaic mounting bracket 4 rotates upward. The rotation of the photovoltaic mounting bracket 4 drives the sliding rod 32 to rotate upward. During the upward rotation, the sliding rod 32 extends outward along the sliding groove 33, and the sliding rod 32 drives multiple ratchet teeth 35 to move upward together. At this time, the locking rod 37 moves unidirectionally along the arc surface set on the ratchet teeth 35. Whenever the locking rod 37 separates from a ratchet tooth 35, the torsion spring returns to its original state, driving the cam 36 to reset. At this time, the locking rod 37 resets and is limited by the lower end of the previous ratchet tooth 35. When the locking rod 37 moves downward, it drives the cam 36 to rotate upward. At this time, the upper end of the locking plate 310 will engage with the clearance groove 311 on the cam 36.

[0046] At this point, continue to pull the photovoltaic mounting bracket 4 upward to separate the locking plate 310 from the clearance groove 311 until the locking rod 37 moves to the unlocking groove 39. Since the arc surface at the upper end of the unlocking groove 39 is higher than the arc surface at the upper end of the ratchet 35, the angle of the upward rotation of the cam 36 increases. At this point, the upper end of the locking plate 310 will engage with the slot 312 on the cam 36. At this point, the locking rod 37 will lift up and remain locked. At this point, the locking rod 37 can move freely within the limiting groove 34 without touching the ratchet 35.

[0047] Then, the photovoltaic mounting frame 4 is rotated downwards, causing the sliding rod 32 to rotate downwards. The sliding rod 32 moves inwards along the slide groove 33 and retracts. At this time, the locking rod 37 will be in the locking groove 38 on the sliding rod 32. Under the action of the upper arc surface of the locking groove 38, the cam 36 rotates downwards. At this time, the torsion spring resets, causing the locking plate 310 to separate from the slot 312. At this time, the photovoltaic mounting frame 4 is in a horizontal state, and the photovoltaic panel installation operation can be carried out. After the installation is completed, the photovoltaic mounting frame 4 is pulled upwards. At this time, the locking rod 37 can only move downwards under the action of the ratchet 35, realizing the multi-angle self-locking adjustment of the photovoltaic mounting frame 4.

[0048] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
