Description

Technical Field

[0001] The utility model relates to the technical field of solar photovoltaic panels, and more specifically, to a solar photovoltaic panel. Background Art

[0002] Existing photovoltaic panels generate electricity by receiving sunlight, so the angle of the photovoltaic panel is an important factor affecting the power generation of the solar panel.

[0003] Therefore, the utility model proposes a solar photovoltaic panel capable of arbitrarily adjusting the angle of the photovoltaic panel. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a solar photovoltaic panel capable of arbitrarily adjusting the angle of the photovoltaic panel, which solves the problem of difficult angle adjustment of existing solar photovoltaic panels.

[0005] A first aspect of the utility model proposes a solar photovoltaic panel.

[0006] In view of this, a solar photovoltaic panel proposed by a first aspect of the utility model includes: a first connecting member including a first damping rotating shaft; a first photovoltaic panel, one end of which is rotatably mounted on the first damping rotating shaft, and the first photovoltaic panel can be locked relative to the first damping rotating shaft at a plurality of rotating positions; a second photovoltaic panel, one end of which is rotatably mounted on the first damping rotating shaft, and the second photovoltaic panel can be locked relative to the first damping rotating shaft at a plurality of rotating positions.

[0007] The solar photovoltaic panel provided by the utility model includes: a first connecting member, a first photovoltaic panel and a second photovoltaic panel. The first connecting member includes a first damping rotating shaft. One end of the first photovoltaic panel is rotatably mounted on the first damping rotating shaft, and the first photovoltaic panel can be locked relative to the first damping rotating shaft at a plurality of rotating positions. One end of the second photovoltaic panel is rotatably mounted on the first damping rotating shaft, and the second photovoltaic panel can be locked relative to the first damping rotating shaft at a plurality of rotating positions. The first photovoltaic panel and the second photovoltaic panel support each other. Through the first damping rotating shaft, the first photovoltaic panel and the second photovoltaic panel can be restricted, thereby suppressing the movement tendency of the first photovoltaic panel and the second photovoltaic panel, ensuring that the first photovoltaic panel and the second photovoltaic panel can maintain at a specified angle, and overcoming the tendency of the first photovoltaic panel and the second photovoltaic panel to flatten downward due to their weight. Specifically, the rotation between the first photovoltaic panel and the second photovoltaic panel can be adjusted infinitely, that is, it can stay at any angle, or the rotation between the first photovoltaic panel and the second photovoltaic panel has a finite number of rotating positions, such as setting 10 or 20 specific rotating positions.

[0008] According to the solar photovoltaic panel provided by the utility model, the following additional technical features may also be included:

[0009] In some possible designs, optionally, the first connecting member further includes: a first torsion spring installed on the first damping rotating shaft. The first torsion spring includes two first spring arms, one of the two first spring arms is arranged on the front surface of the first photovoltaic panel, and the other of the two first spring arms is arranged on the front surface of the second photovoltaic panel.

[0010] In this design, the first connecting member further includes a first torsion spring. The first torsion spring is installed on the first damping rotating shaft. One of the two first spring arms of the first torsion spring is arranged on the front surface of the first photovoltaic panel, and the other of the two first spring arms is arranged on the front surface of the second photovoltaic panel. At the same time, the first torsion spring is provided and it is defined that the two first spring arms of the first torsion spring are arranged on the opposite sides of the first photovoltaic panel and the second photovoltaic panel, that is, the front surfaces of the first photovoltaic panel and the second photovoltaic panel, so that the first spring arms can apply an inward contracting force to the first photovoltaic panel and the second photovoltaic panel. Due to gravity, the mutually supported first photovoltaic panel and the second photovoltaic panel will flatten downward, that is, gravity will apply an outward expanding force to the first photovoltaic panel and the second photovoltaic panel. The first torsion spring can balance the outward expanding force of gravity on the first photovoltaic panel and the second photovoltaic panel, so that the first photovoltaic panel and the second photovoltaic panel can be fixed at the required angle. At the same time, the first torsion spring can be improved according to actual needs. By changing the elastic coefficient of the first torsion spring, a suitable first torsion spring can be found to balance the outward expanding force of the first photovoltaic panel and the second photovoltaic panel due to gravity. Further, the requirement of the first damping rotating shaft for balancing gravity can be reduced. Especially when the weights of the first photovoltaic panel and the second photovoltaic panel are relatively large, the first damping rotating shaft alone may not be able to balance the weights of the first photovoltaic panel and the second photovoltaic panel. Through the additionally provided first torsion spring, the contracting force of the first torsion spring can balance the force of the first damping rotating shaft, thus offsetting the influence of gravity. At the same time, the damping intensity of the first damping rotating shaft can be reduced, and the user can use a smaller force to adjust the angles of the first photovoltaic panel and the second photovoltaic panel.

[0011] In some possible designs, optionally, the solar photovoltaic panel further includes: a first bushing installed at one end of the first photovoltaic panel and sleeved on the first damping rotating shaft, and one end of the first photovoltaic panel is rotatably installed on the first damping rotating shaft through the first bushing; a second bushing installed at one end of the second photovoltaic panel and sleeved on the first damping rotating shaft, and one end of the second photovoltaic panel is rotatably installed on the first damping rotating shaft through the second bushing.

[0012] In this design, the solar photovoltaic panel further includes: a first bushing and a second bushing. The first bushing is installed at one end of the first photovoltaic panel, and the second bushing is installed at one end of the second photovoltaic panel. Both the first bushing and the second bushing are sleeved on the first damping rotating shaft. One end of the first photovoltaic panel is rotatably installed on the first damping rotating shaft through the first bushing, and one end of the second photovoltaic panel is rotatably installed on the first damping rotating shaft through the second bushing. Connecting the first damping rotating shaft through the bushings can ensure the connection strength between the photovoltaic panel and the first damping rotating shaft.

[0013] Furthermore, the first photovoltaic panel and the first bushing are integrally formed, and the second photovoltaic panel and the second bushing are integrally formed.

[0014] In some possible designs, optionally, one of the first pointer and the first scale is provided on at least one first bushing, and the other of the first pointer and the first scale is provided on at least one second bushing. The rotation angle between the first photovoltaic panel and the second photovoltaic panel can be indicated by the first pointer and the first scale.

[0015] In this design, the first pointer and the first scale are respectively provided on at least one first bushing and at least one second bushing. The rotation angle between the first photovoltaic panel and the second photovoltaic panel can be indicated by the first pointer and the first scale, so that the user can intuitively determine the rotation angle between the first photovoltaic panel and the second photovoltaic panel, and then adjust the angle between the first photovoltaic panel and the second photovoltaic panel, so that the first photovoltaic panel or the second photovoltaic panel can be closer to the direct sunlight.

[0016] In some possible designs, optionally, the first bushing includes a plurality of first sub-bushings, the second bushing includes a plurality of second sub-bushings, and the plurality of first sub-bushings and the plurality of second sub-bushings are alternately arranged on the first damping rotating shaft.

[0017] In this design, the first bushing includes a plurality of first sub-bushings, and the second bushing includes a plurality of second sub-bushings. By alternately arranging the plurality of first sub-bushings and the plurality of second sub-bushings on the first damping rotating shaft, the connection strength between the first photovoltaic panel and the second photovoltaic panel and the first damping rotating shaft is improved, and the misalignment of the first photovoltaic panel and the second photovoltaic panel in position can be prevented.

[0018] In some possible designs, optionally, the first pointer and the first scale are respectively provided on at least one group of adjacent first sub-bushings and second sub-bushings. The rotation angle between the first photovoltaic panel and the second photovoltaic panel can be indicated by the first pointer and the first scale.

[0019] In this design, the rotation angle between the first photovoltaic panel and the second photovoltaic panel can be indicated by the first pointer and the first scale, enabling the user to intuitively determine the rotation angle between the first photovoltaic panel and the second photovoltaic panel, and thus adjust the angle between the first photovoltaic panel and the second photovoltaic panel so that the first photovoltaic panel or the second photovoltaic panel can be closer to the direct sunlight.

[0020] In some possible designs, optionally, the first photovoltaic panel is a single-sided solar panel or a double-sided solar panel; the second photovoltaic panel is a single-sided solar panel or a double-sided solar panel.

[0021] In this design, during actual use, since the first photovoltaic panel and the second photovoltaic panel support each other, only one of the first photovoltaic panel and the second photovoltaic panel can receive direct sunlight, and the other of the first photovoltaic panel and the second photovoltaic panel can only receive ambient reflected light for power generation, and the backs of the first photovoltaic panel and the second photovoltaic panel are exactly opposite to each other. That is to say, the ambient reflected light received by the backs of the first photovoltaic panel and the second photovoltaic panel is less. Therefore, the first photovoltaic panel and the second photovoltaic panel can be set as single-sided solar panels. At the same time, the first photovoltaic panel and the second photovoltaic panel can also both use double-sided solar panels. Although the light received by the back is less, it can still receive the reflected light from the environment and then generate electricity to improve the power generation efficiency.

[0022] In some possible designs, optionally, the first photovoltaic panel, the second photovoltaic panel and the first connecting member form a photovoltaic panel group, and the number of photovoltaic panel groups is multiple. The multiple photovoltaic panel groups are connected by a second connecting member to form a foldable structure.

[0023] In this design, the first photovoltaic panel, the second photovoltaic panel and the first connecting member form a photovoltaic panel group, and the number of photovoltaic panel groups is multiple. The multiple photovoltaic panel groups are connected by a second connecting member to form a foldable structure, which can connect multiple photovoltaic panel groups, thus facilitating the installation and arrangement of the photovoltaic panel groups.

[0024] In some possible designs, optionally, the second connecting member includes a connecting shaft, and any two adjacent photovoltaic panel groups are rotationally connected by the connecting shaft.

[0025] In this design, the second connecting member includes a connecting shaft, and any two adjacent photovoltaic panel groups are rotationally connected by the connecting shaft. Connecting through the rotating shaft is more convenient, the structure is relatively simple, and it can ensure the connection strength between different photovoltaic panel groups. And connecting through the rotating shaft facilitates folding the photovoltaic panel groups.

[0026] In some possible designs, optionally, a second pointer is provided on one of any two adjacent photovoltaic panel groups, and a second scale is provided on the other of any two adjacent photovoltaic panel groups. The rotation angle between any two adjacent photovoltaic panel groups can be indicated by the second pointer and the second scale.

[0027] In some possible designs, optionally, the connecting shaft is a second damping rotating shaft.

[0028] In this design, the second damping rotating shaft can suppress the movement trend of the photovoltaic panels in the photovoltaic panel group, ensure that the photovoltaic panels can be maintained at a specified angle, and overcome the trend of the photovoltaic panels to flatten downward caused by their weight.

[0029] In some possible designs, optionally, the second connecting member further includes: a second torsion spring, and the second torsion spring includes two second spring arms, and the two second spring arms are respectively arranged on the back surfaces of two adjacent photovoltaic panel groups.

[0030] In this design, the two second spring arms are respectively arranged on the back surfaces of two adjacent photovoltaic panel groups, so that the force for two adjacent photovoltaic panel groups to contract inward. Due to gravity, the mutually supported two adjacent photovoltaic panel groups will flatten downward, that is to say, gravity will give an outward expansion force to two adjacent photovoltaic panel groups. The second torsion spring can balance the outward expansion force of gravity on two adjacent photovoltaic panel groups, so that two adjacent photovoltaic panel groups can be fixed at a required angle.

[0031] In the solar photovoltaic panel of the present utility model, the first photovoltaic panel and the second photovoltaic panel use a damping rotating shaft to maintain the opening and closing angle of the photovoltaic panel adjusted by the user. A torsion spring is used in the middle of the damping rotating shaft to counteract the gravity of the photovoltaic panel, so that the photovoltaic panel keeps a certain angle with the ground. There are scales on the shaft sleeve to indicate the included angle between the photovoltaic panel and the ground, which is more convenient for the user to adjust the photovoltaic panel to a desired angle. The torsion spring cooperates with the damping rotating shaft to achieve the purpose of freely adjusting the angle of the photovoltaic panel. At the same time, since the torsion force provided by the torsion spring at different angles is inconsistent, there is always a certain gap with the torsion force caused by the gravity of the photovoltaic panel. Using the damping rotating shaft can balance this gap.

[0045] The solar photovoltaic panel provided by the present utility model includes: a first connecting member 10, a first photovoltaic panel 12 and a second photovoltaic panel 14. Among them, the first connecting member 10 includes a first damping rotating shaft 102. One end of the first photovoltaic panel 12 is rotatably mounted on the first damping rotating shaft 102, and the first photovoltaic panel 12 can be locked relative to the first damping rotating shaft 102 at a plurality of rotating positions. One end of the second photovoltaic panel 14 is rotatably mounted on the first damping rotating shaft 102, and the second photovoltaic panel 14 can be locked relative to the first damping rotating shaft 102 at a plurality of rotating positions. The first photovoltaic panel 12 and the second photovoltaic panel 14 support each other. Through the first damping rotating shaft 102, the movement trends of the first photovoltaic panel 12 and the second photovoltaic panel 14 can be restricted, thereby suppressing the movement trends of the first photovoltaic panel 12 and the second photovoltaic panel 14, ensuring that the first photovoltaic panel 12 and the second photovoltaic panel 14 can be maintained at a specified angle, and overcoming the tendency of the first photovoltaic panel 12 and the second photovoltaic panel 14 to flatten downward due to their weights. Specifically, the rotation between the first photovoltaic panel 12 and the second photovoltaic panel 14 can be adjusted steplessly, that is, it can stay at any angle, or the rotation between the first photovoltaic panel 12 and the second photovoltaic panel 14 has a finite number of rotating positions, such as setting 10 or 20 specific rotating positions.

[0046] According to the solar photovoltaic panel provided by the present utility model, it may also have the following additional technical features:

[0047] In some possible embodiments, optionally, the first connecting member 10 further includes: a first torsion spring 104, mounted on the first damping rotating shaft 102, the first torsion spring 104 includes two first spring arms 106, one of the two first spring arms 106 is disposed on the front surface of the first photovoltaic panel 12, and the other of the two first spring arms 106 is disposed on the front surface of the second photovoltaic panel 14.

[0048] In this embodiment, the first connecting member 10 further includes a first torsion spring 104. The first torsion spring 104 is installed on the first damping rotating shaft 102. One of the two first spring arms 106 of the first torsion spring 104 is disposed on the front surface of the first photovoltaic panel 12, and the other of the two first spring arms 106 is disposed on the front surface of the second photovoltaic panel 14. At the same time, the first torsion spring 104 is provided and it is defined that the two first spring arms 106 of the first torsion spring 104 are disposed on the opposite sides of the first photovoltaic panel 12 and the second photovoltaic panel 14, that is, the front surfaces of the first photovoltaic panel 12 and the second photovoltaic panel 14, so that the first spring arms 106 can apply a force for the first photovoltaic panel 12 and the second photovoltaic panel 14 to contract inward. Due to gravity, the mutually supporting first photovoltaic panel 12 and second photovoltaic panel 14 will flatten downward, that is to say, gravity will apply a force for the first photovoltaic panel 12 and the second photovoltaic panel 14 to expand outward. The first torsion spring 104 can balance the force of gravity on the first photovoltaic panel 12 and the second photovoltaic panel 14 to expand outward, so that the first photovoltaic panel 12 and the second photovoltaic panel 14 can be fixed at the required angle. At the same time, the first torsion spring 104 can be improved according to actual needs. By changing the elastic coefficient of the first torsion spring 104, a suitable first torsion spring 104 can be found to balance the force of the first photovoltaic panel 12 and the second photovoltaic panel 14 to expand outward due to gravity. Further, the requirement of the first damping rotating shaft 102 for balancing gravity can be reduced. Especially when the weights of the first photovoltaic panel 12 and the second photovoltaic panel 14 are relatively large, the first damping rotating shaft 102 alone may not be able to balance the weights of the first photovoltaic panel 12 and the second photovoltaic panel 14. Through the additionally provided first torsion spring 104, the contraction force of the first torsion spring 104 can balance the force of the first damping rotating shaft 102, thereby offsetting the influence of gravity, and at the same time, the damping strength of the first damping rotating shaft 102 can be reduced, and the user can use a smaller force to adjust the angles of the first photovoltaic panel 12 and the second photovoltaic panel 14.

[0049] In some possible embodiments, optionally, as Figure 2 shown, the solar photovoltaic panel further includes: a first bushing 16, installed at one end of the first photovoltaic panel 12 and sleeved on the first damping rotating shaft 102, and one end of the first photovoltaic panel 12 is rotatably installed on the first damping rotating shaft 102 through the first bushing 16; a second bushing 18, installed at one end of the second photovoltaic panel 14 and sleeved on the first damping rotating shaft 102, and one end of the second photovoltaic panel 14 is rotatably installed on the first damping rotating shaft 102 through the second bushing 18.

[0050] In this embodiment, the solar photovoltaic panel further includes: a first bushing 16 and a second bushing 18. The first bushing 16 is installed at one end of the first photovoltaic panel 12, and the second bushing 18 is installed at one end of the second photovoltaic panel 14. Both the first bushing 16 and the second bushing 18 are sleeved on the first damping rotating shaft 102. One end of the first photovoltaic panel 12 is rotatably installed on the first damping rotating shaft 102 through the first bushing 16, and one end of the second photovoltaic panel 14 is rotatably installed on the first damping rotating shaft 102 through the second bushing 18. Connecting the first damping rotating shaft 102 through the bushing can ensure the connection strength between the photovoltaic panel and the first damping rotating shaft 102.

[0051] Furthermore, the first photovoltaic panel 12 and the first bushing 16 are integrally formed, and the second photovoltaic panel 14 and the second bushing 18 are integrally formed.

[0052] In some possible embodiments, optionally, as Figure 3 shown, one of the first pointer 2 and the first scale 3 is provided on at least one first bushing 16, and the other of the first pointer 2 and the first scale 3 is provided on at least one second bushing 18. The rotation angle between the first photovoltaic panel 12 and the second photovoltaic panel 14 can be indicated by the first pointer 2 and the first scale 3.

[0053] In this embodiment, the first pointer 2 and the first scale 3 are respectively provided on at least one first bushing 16 and at least one second bushing 18. The rotation angle between the first photovoltaic panel 12 and the second photovoltaic panel 14 can be indicated by the first pointer 2 and the first scale 3, so that the user can intuitively determine the rotation angle between the first photovoltaic panel 12 and the second photovoltaic panel 14, and then adjust the angle between the first photovoltaic panel 12 and the second photovoltaic panel 14, so that the first photovoltaic panel 12 or the second photovoltaic panel 14 can be closer to the direct sunlight.

[0054] In some possible embodiments, optionally, the first bushing 16 includes a plurality of first sub-bushings 162, the second bushing 18 includes a plurality of second sub-bushings 182, and the plurality of first sub-bushings 162 and the plurality of second sub-bushings 182 are alternately arranged on the first damping rotating shaft 102.

[0055] In this embodiment, the first bushing 16 includes a plurality of first sub-bushings 162, and the second bushing 18 includes a plurality of second sub-bushings 182. By alternately arranging the plurality of first sub-bushings 162 and the plurality of second sub-bushings 182 on the first damping rotating shaft 102, the connection strength between the first photovoltaic panel 12 and the second photovoltaic panel 14 and the first damping rotating shaft 102 is improved, and the misalignment of the first photovoltaic panel 12 and the second photovoltaic panel 14 in position can be prevented.

[0056] In some possible embodiments, optionally, as Figure 3As shown, at least one set of adjacent first sub-bushings 162 and second sub-bushings 182 are respectively provided with a first pointer 2 and a first scale 3. The rotation angle between the first photovoltaic panel 12 and the second photovoltaic panel 14 can be indicated by the first pointer 2 and the first scale 3.

[0057] In this embodiment, the rotation angle between the first photovoltaic panel 12 and the second photovoltaic panel 14 can be indicated by the first pointer 2 and the first scale 3, so that the user can intuitively determine the rotation angle between the first photovoltaic panel 12 and the second photovoltaic panel 14, and then adjust the angle between the first photovoltaic panel 12 and the second photovoltaic panel 14, so that the first photovoltaic panel 12 or the second photovoltaic panel 14 can be closer to the direct sunlight.

[0058] In some possible embodiments, optionally, the first photovoltaic panel 12 is a single-sided solar panel or a double-sided solar panel; the second photovoltaic panel 14 is a single-sided solar panel or a double-sided solar panel.

[0059] In this embodiment, during actual use, since the first photovoltaic panel 12 and the second photovoltaic panel 14 support each other, only one of the first photovoltaic panel 12 and the second photovoltaic panel 14 can receive direct sunlight, and the other of the first photovoltaic panel 12 and the second photovoltaic panel 14 can only receive ambient reflected light for power generation, and the backs of the first photovoltaic panel 12 and the second photovoltaic panel 14 are exactly opposite to each other. That is to say, the ambient reflected light received by the backs of the first photovoltaic panel 12 and the second photovoltaic panel 14 is less, so the first photovoltaic panel 12 and the second photovoltaic panel 14 can be provided with single-sided solar panels. At the same time, the first photovoltaic panel 12 and the second photovoltaic panel 14 can also both use double-sided solar panels. Although the light received by the back is less, it can still receive the ambient reflected light and then generate electricity to improve the power generation efficiency.

[0060] The front of the single-sided solar panel is the side that can absorb light energy for power generation, and the back is the side that cannot absorb light energy for power generation. For the double-sided solar panel, the sides of the first photovoltaic panel 12 and the second photovoltaic panel 14 facing away from each other are the fronts, and the sides of the first photovoltaic panel 12 and the second photovoltaic panel 14 facing each other are the backs.

[0061] In some possible embodiments, optionally, as Figure 4 shown, the first photovoltaic panel 12, the second photovoltaic panel 14 and the first connecting member 10 form a photovoltaic panel group 1. The number of photovoltaic panel groups 1 is multiple, and the multiple photovoltaic panel groups 1 are connected by a second connecting member 4 to form a foldable structure.

[0062] In this embodiment, the first photovoltaic panel 12, the second photovoltaic panel 14, and the first connecting member 10 form a photovoltaic panel group 1. The number of photovoltaic panel groups 1 is multiple, and multiple photovoltaic panel groups 1 are connected by the second connecting member 4 to form a foldable structure, which can connect multiple photovoltaic panel groups 1, thereby facilitating the installation and arrangement of the photovoltaic panel groups 1.

[0063] In some possible embodiments, optionally, the second connecting member 4 includes a connecting shaft 40, and any two adjacent photovoltaic panel groups 1 are rotatably connected by the connecting shaft 40.

[0064] In this embodiment, the second connecting member 4 includes a connecting shaft 40, and any two adjacent photovoltaic panel groups 1 are rotatably connected by the connecting shaft 40. Connecting through a rotating shaft is more convenient, the structure is relatively simple, and it can ensure the connection strength between different photovoltaic panel groups 1. Moreover, connecting through a rotating shaft facilitates folding the photovoltaic panel groups 1.

[0065] In some possible embodiments, optionally, a second pointer 5 is provided on one of any two adjacent photovoltaic panel groups 1, and a second scale 6 is provided on the other of any two adjacent photovoltaic panel groups 1. The rotation angle between any two adjacent photovoltaic panel groups 1 can be indicated by the second pointer 5 and the second scale 6.

[0066] In some possible embodiments, optionally, as Figure 5 shown, the connecting shaft 40 is a second damping rotating shaft 402.

[0067] In this embodiment, the second damping rotating shaft 402 can inhibit the movement tendency of the photovoltaic panels in the photovoltaic panel group 1, ensure that the photovoltaic panels can maintain at a specified angle, and overcome the tendency of the photovoltaic panels to flatten downward due to their weight.

[0068] In some possible embodiments, optionally, as Figure 5 shown, the second connecting member 4 further includes: a second torsion spring 42. The second torsion spring 42 includes two second spring arms 422, and the two second spring arms 422 are respectively arranged on the backs of two adjacent photovoltaic panel groups 1.

[0069] In this embodiment, the two second spring arms 422 are respectively arranged on the backs of two adjacent photovoltaic panel groups 1, so that there is a force for two adjacent photovoltaic panel groups 1 to contract inward. However, due to gravity, the two adjacent photovoltaic panel groups 1 that support each other will flatten downward. That is to say, gravity will give a force for two adjacent photovoltaic panel groups 1 to expand outward. The second torsion spring 42 can balance the force of gravity on the outward expansion of two adjacent photovoltaic panel groups 1, so that two adjacent photovoltaic panel groups 1 can be fixed at the required angle.

[0070] In the solar photovoltaic panel of the present utility model, the first photovoltaic panel 12 and the second photovoltaic panel 14 use a damping rotating shaft to maintain the opening and closing angle of the photovoltaic panel adjusted by the user. A torsion spring is used in the middle of the damping rotating shaft to counteract the gravity of the photovoltaic panel, so that the photovoltaic panel maintains a certain angle with the ground. There are scales on the shaft sleeve to indicate the included angle between the photovoltaic panel and the ground, which is more convenient for the user to adjust the photovoltaic panel to the desired angle. The torsion spring cooperates with the damping rotating shaft to achieve the purpose of freely adjusting the angle of the photovoltaic panel. At the same time, since the torsion force provided by the torsion spring at different angles is inconsistent, there is always a certain gap with the torsion force caused by the gravity of the photovoltaic panel. Using a damping rotating shaft can balance this gap.

[0071] The specific implementation method is as follows: The overall structure of the component is as Figure 1 shown. Multiple photovoltaic panels are placed on the ground and form a certain included angle with the ground. The number of photovoltaic panels is not limited to two, and any even number is also possible. Multiple shaft sleeves and a connecting shaft 40 are used to connect between two photovoltaic panels. A torsion spring is wound around the connecting shaft 40.

[0072] As Figure 2 shown, the torsion spring is wound around the connecting shaft 40. The torsion spring arms are located outside the photovoltaic panel and apply an inward force to the photovoltaic panel to prevent the photovoltaic panel from continuing to open outward due to gravity. The shaft sleeve is located inside the photovoltaic panel and is connected to the photovoltaic panel, and the rotation of the shaft sleeve drives the opening and closing of the photovoltaic panel. The connection method between the shaft sleeve and the photovoltaic panel can be screwed or bonded, or the shaft sleeve and the photovoltaic panel are integrally formed. A damping material is added between the connecting shaft 40 and the shaft sleeve to generate a damping force when the first photovoltaic panel 12 and the second photovoltaic panel 14 rotate.

[0073] The angle indication system is as Figure 3 shown. The first shaft sleeve 16 and the second shaft sleeve 18 are sleeved on the damping shaft. It can be seen that when the component adjusts the angle: the first shaft sleeve 16 will rotate with the first photovoltaic panel 12, and the second shaft sleeve 18 will rotate with the second photovoltaic panel 14. Scales and pointers are marked on the first shaft sleeve 16 and the second shaft sleeve 18 respectively. Thus, the angle of the photovoltaic module can be reflected by the scale indicated by the pointer.

[0074] The beneficial effects are as follows:

[0075] The torsion spring cooperates with the damping rotating shaft to achieve the purpose of freely adjusting the angle of the photovoltaic panel.

[0076] If only a damping rotating shaft is used to counteract the gravity of the photovoltaic panel, a very large damping is required, which is not convenient for the user to operate. Using a torsion spring to offset part of the gravity can reduce the required damping.

[0077] Since the torsion force provided by the torsion spring at different angles is inconsistent, there is always a certain gap with the torsion force caused by the gravity of the photovoltaic panel. Using a damping rotating shaft can balance this gap.

[0078] Add scales on the bushing to indicate the current angle, which is more convenient for users to adjust the photovoltaic panel to the desired angle.
