[0002] Compared with rigid photovoltaic support structures, flexible photovoltaic support structures have stronger terrain adaptability and can provide a wide clearance for the use of lower space. However, since flexible supports usually connect multiple photovoltaic panels together with a cable structure, in order to achieve the angle adjustment of photovoltaic panels according to the sun's position similar to the rigid photovoltaic support tracking structure, improve the utilization of solar energy in different time periods and seasons, and ensure that the angles of all photovoltaic panels on the flexible support face the sun's position to the maximum extent, the technology needs to be improved.

[0003] At present, the flexible photovoltaic brackets existing in the prior art can only adjust the angle in one direction when adjusting the angle of the photovoltaic panel, but cannot adjust two angles at the same time.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0040] This application provides an embodiment of a bidirectionally adjustable flexible photovoltaic bracket. For details, please refer to Figures 1 to 5 .

[0041] The bidirectionally adjustable flexible photovoltaic bracket in this embodiment includes: a first bracket 1 and a second bracket 2, a support platform 4 is arranged on the top of the first bracket 1 and the second bracket 2, a first elastic lifting mechanism 5 and a second elastic lifting mechanism 6 are arranged on the support platform 4 at intervals, a first cable 11 is overlapped between the first elastic lifting mechanism 5 on the first bracket 1 and the first elastic lifting mechanism 5 on the second bracket 2, a second cable 12 is overlapped between the second elastic lifting mechanism 6 on the first bracket 1 and the second elastic lifting mechanism 6 on the second bracket 2, and the first cable 11 and the second cable 12 are used for erecting and fixing the photovoltaic panel 3.

[0042] It should be noted that: the flexible photovoltaic bracket can adjust the angle of the photovoltaic panel 3 by directly tightening or loosening the cables (the first cable 11 and the second cable 12), and the height difference between the first cable 11 and the second cable 12 and the height difference between the two ends of the first cable 11 and the second cable 12 are achieved by the first elastic lifting mechanism 5 and the second elastic lifting mechanism 6 on the first bracket 1 and the second bracket 2. It has a simple structure, is easy to operate, and is convenient for construction, installation, maintenance and replacement. There is no need to modify the bracket structure or add additional processing devices to each photovoltaic panel 3, which can significantly reduce manufacturing costs.

[0043] The above is an embodiment of a bidirectionally adjustable flexible photovoltaic bracket provided in the embodiment of the present application. The following is an embodiment of a bidirectionally adjustable flexible photovoltaic bracket provided in the embodiment of the present application. For details, please refer to Figures 1 to 7 .

[0044] The bidirectionally adjustable flexible photovoltaic bracket in this embodiment includes: a first bracket 1 and a second bracket 2, the tops of the first bracket 1 and the second bracket 2 are both provided with a support platform 4, the support platform 4 is provided with a first elastic lifting mechanism 5 and a second elastic lifting mechanism 6 at intervals, a first cable 11 is overlapped between the first elastic lifting mechanism 5 on the first bracket 1 and the first elastic lifting mechanism 5 on the second bracket 2, a second cable 12 is overlapped between the second elastic lifting mechanism 6 on the first bracket 1 and the second elastic lifting mechanism 6 on the second bracket 2, and the first cable 11 and the second cable 12 are used to set up and fix the photovoltaic panel 3. Specifically, the first bracket 1 and the second bracket 2 can be set as a height-adjustable structure.

[0045] It is understandable that when either end of the first cable 11 or the second cable 12 is tightened, the elevation of the connection point between the first cable 11 or the second cable 12 and its tightening side bracket (the first bracket 1 or the second bracket 2) will decrease, and conversely, when relaxed, it will increase under the action of elasticity.

[0046] The first elastic lifting mechanism 5 and the second elastic lifting mechanism 6 both include a cable limiter and a cable elastic supporter, and the cable limiter and the cable elastic supporter are both fixed on the supporting platform 4 .

[0047] The cable limiting member comprises a U-shaped plate 7, on which a vertical moving channel for limiting the cable is provided.

[0048] The cable elastic support member includes an elastic member, a pad 9 and a pulley 10, one end of the elastic member is fixedly connected to the support platform 4, and the other end is fixedly connected to the pad 9, the pulley 10 is arranged on the pad 9, and the two ends of the pulley 10 are respectively in contact with the inner walls of both sides of the U-shaped plate 7. Specifically, the elastic member can be a spring 8.

[0049] It can be understood that the cable and the elastic member are connected through the pulley 10 and the pad 9. The function of the elastic member is to bear the force and adjust the elevation of the connection point between the first cable 11 or the second cable 12 and the bracket (the first bracket 1 or the second bracket 2) through deformation; the function of the pulley 10 is to change the direction of the cable force and reduce the physical wear of the cable when the cable is pulled.

[0050] It should be noted that the pulley 10 is connected to the U-shaped plate 7 by contact, and no other restraining device is used, so that the spring 8 and the pulley 10 can be easily repaired and replaced. When in use, the force direction of the pulley 10 is as follows: Figure 7 As shown, the pulley 10 is firmly pressed on the backing plate 9 and can only move up and down in a predetermined direction.

[0051] A limiting slideway for limiting the position of the pulley 10 may also be provided on the inner side wall of the U-shaped plate 7 .

[0052] An arc-shaped groove for contacting the pulley 10 is provided on the top of the pad 9 .

[0053] The function of the backing plate 9 is to connect the elastic member and the pulley 10. When in use, a small amount of lubricant can be applied to the arc-shaped groove to reduce the friction of the pulley 10 when sliding.

[0054] A support baffle 13 is provided on the periphery of the U-shaped plate 7, one end of the support baffle 13 is fixedly connected to the U-shaped plate 7, and the other end is fixedly connected to the support platform 4. The local stability can be improved by providing the support baffle 13. Specifically, a connecting plate 14 is provided between the two U-shaped plates 7 on the first bracket 1 and between the two U-shaped plates 7 on the second bracket 2 to further improve the overall stability.

[0055] The system further comprises: a first motor, a second motor, a third motor and a fourth motor. The first motor and the second motor are used to pull the two ends of the first cable 11 , and the third motor and the fourth motor are used to pull the two ends of the second cable 12 .

[0056] In specific implementation, the first bracket 1 and the second bracket 2 are installed in the north-south direction, and a certain elevation difference can be set first according to the latitude of the location. The elevation difference that can be changed between the first bracket 1 and the second bracket 2 is small, and the change in the direct sunlight angle caused by the change of seasons (north-south direction) is small, which can better meet the angle adjustment in the north-south direction. The elevation difference between the two springs 8 on the same bracket (the first bracket 1 or the second bracket 2) is used to adjust the change in the direct sunlight angle caused by the sun rising in the east and setting in the west (east-west direction). The adjustable range is large, which can better meet the angle adjustment in the east-west direction. At the beginning of installation, a certain sag is retained for the first cable 11 and the second cable 12 to facilitate the contraction of the cable for adjustment. At the same time, the first motor and the second motor are placed at both ends of the first cable 11, and the positions are fixed. The third motor and the fourth motor are placed at both ends of the second cable 12, and the positions are fixed. By using the first motor, the second motor, the third motor and the fourth motor to pull the cable or relax the cable, the angle adjustment in two directions can be achieved at the same time.

[0057] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
