[0002] Building-integrated photovoltaics (BIPV) is a technology that integrates photovoltaic modules into building structures, which can generate clean energy while providing building material functions. In BIPV systems, photovoltaic panels are usually installed on the facade of a building. Due to the limitation of the lighting angle of the facade, photovoltaic panels cannot effectively receive sunlight, thus affecting their power generation efficiency.

[0003] In order to optimize the light received by photovoltaic panels, photovoltaic brackets are usually used to adjust their orientation. However, the photovoltaic bracket designs currently on the market generally have limitations and can only adjust the vertical angle. This limitation prevents photovoltaic panels from fully utilizing the sunlight conditions throughout the day, limiting the improvement of power generation efficiency.

[0004] In addition, some photovoltaic brackets are vertical brackets, which are generally fixed on a horizontal plane. The rotation angle of the photovoltaic panel in the horizontal direction is adjusted by rotating the vertical bracket. However, this type of vertical bracket has certain limitations in use. It generally needs to be installed and fixed on a relatively horizontal plane, which inevitably takes up too much space. However, for vertical walls, in order to install more photovoltaic panels within a limited wall area, it is not suitable to use vertical brackets. Utility Model Content

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0038] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0039] The embodiment of the present application provides a photovoltaic panel posture adjustment device installed on the surface of a facade structure. Figures 1 to 5 As shown, the photovoltaic panel posture adjustment device includes a photovoltaic bracket 10 and a photovoltaic panel 20.

[0040] Wherein, the photovoltaic bracket 10 includes a supporting frame 1, a telescopic mechanism 2, a rotating member 3 and a driving mechanism 4. The supporting frame 1 includes a first end and a second end, the first end is hinged to a first predetermined position of the facade structure, and the rotation axis of the hinged position is parallel to the horizontal plane, and the second end is located below the first end. The direction from the first end to the second end of the supporting frame 1 is defined as the n direction. The telescopic mechanism 2 is arranged between the second end of the supporting frame 1 and the facade structure, one end of which is hinged to the second end of the supporting frame 1, and the other end is hinged to the second predetermined position of the facade structure, and the second predetermined position is located below the first predetermined position. The rotating member 3 is rotatably mounted on the supporting frame 1, and the rotation axis of the rotating member 3 is along the n direction. The driving mechanism 4 is mounted on the supporting frame 1, and is used to drive the rotating member 3 to rotate.

[0041] Furthermore, the photovoltaic panel 20 includes a front side and a back side, and the back side is connected and fixed to the rotating member 3 . The photovoltaic panel 20 rotates along with the rotation of the rotating member 3 .

[0042] When the photovoltaic panel posture adjustment device of this embodiment is used, on the one hand, the telescopic length of the telescopic mechanism 2 can be adjusted to change the angle of the support frame 1 relative to the facade structure surface, thereby achieving the vertical angle adjustment of the photovoltaic panel 20; on the other hand, the driving mechanism 4 can drive the rotating member 3 to rotate in a predetermined direction to a predetermined angle, thereby achieving the horizontal angle adjustment of the photovoltaic panel 20. It can be seen that the photovoltaic bracket 10 of the photovoltaic panel posture adjustment device of this embodiment can achieve both the vertical angle adjustment of the photovoltaic panel 20 and the horizontal angle adjustment of the photovoltaic panel 20, so that the photovoltaic panel 20 can track the sun as much as possible, so as to fully utilize the sunlight and improve the power generation efficiency of the photovoltaic panel 20.

[0043] In addition, in the photovoltaic panel posture adjustment device of the present embodiment, the photovoltaic bracket 10 is completely located on the back of the photovoltaic panel 20, so the photovoltaic panel 20 can basically completely cover the photovoltaic bracket 10, with a compact structure and relatively small occupied space, while also improving the aesthetics of the facade.

[0044] In one embodiment, the telescopic mechanism 2 may be, but is not limited to, an electric push rod, a hydraulic cylinder, a pneumatic cylinder, etc.

[0045] In one embodiment, if Figures 2 to 5 , the rotating member 3 of the photovoltaic panel posture adjustment device can be a rotating shaft structure, which is installed on the support frame 1 and extends in the n direction. It should be noted that the rotating member 3 is a rotating shaft structure, which does not represent an optical axis with equal diameters at all locations. In order to facilitate the installation of the rotating member 3 on the support frame 1, a step structure can be machined at a predetermined position of the rotating member 3 to facilitate the installation of the bearing structure to achieve a rotational connection with the support frame 1. In addition, the rotating member 3 and the photovoltaic panel 20 can be connected and fixed by bolt and nut fasteners, a latch structure, and the like.

[0046] In one embodiment, if Figure 2 and Figure 3 As shown, the driving mechanism 4 may include a first motor 411, a first bevel gear 412, and a second bevel gear 413. The first bevel gear 412 is fixedly connected to one end of the rotating member 3, the second bevel gear 413 is mounted on the supporting frame 1 and meshes with the first bevel gear 412, and the first motor 411 is mounted on the supporting frame 1 and is used to drive the second bevel gear 413 to rotate. It should be noted that the first motor 411 can directly drive the second bevel gear 413 to rotate, or a gear set can be added in the middle to drive it indirectly.

[0047] The aforementioned driving mechanism 4 includes a first motor 411 , a first bevel gear 412 and a second bevel gear 413 , which can optimize the structural layout and achieve a compact design.

[0048] In one embodiment, if Figure 4 and Figure 5 As shown, the driving mechanism 4 may include a second motor 421, a first gear 422, and a second gear 423. The first gear 422 is sleeved on the rotating member 3 and fixed, and the first gear 422 is located at a predetermined position between the two ends of the rotating member 3. The second gear 423 is mounted on the supporting frame 1 and meshes with the first gear 422. The second motor 421 is mounted on the supporting frame 1 and is used to drive the second gear 423 to rotate. It should be noted that the second motor 421 can directly drive the second gear 423 to rotate, or indirectly drive it by adding a gear set in the middle.

[0049] Among them, the aforementioned driving mechanism 4 includes a second motor 421, a first gear 422 and a second gear 423, so that the second motor 421 is placed in the middle position of the support frame 1, which is beneficial to optimize the overall mass distribution and the center of gravity position, so that the telescopic mechanism 2 can more easily push the support frame 1 to move, reduce resistance and reduce power consumption.

[0050] In one embodiment, if Figure 6 As shown, the back of the photovoltaic panel 20 may be provided with a plurality of mounting portions 201 arranged in a straight line, and each mounting portion 201 is mounted on the rotating member 3 .

[0051] In one embodiment, if Figure 6 As shown, the mounting portion 201 on the back of the photovoltaic panel 20 is an annular structure, which is sleeved on the rotating member 3, and the mounting portion 201 is connected to the rotating member 3 through a limiting structure, which is used to limit the photovoltaic panel 20 from rotating following the rotation of the rotating member 3.

[0052] In a relatively preferred embodiment, Figure 7 and Figure 8As shown, the limiting structure may include a protruding structure 301 and a groove structure 202; the protruding structure 301 is arranged at the position of the rotating member 3 body surface corresponding to the mounting portion 201, and the protruding structure 301 extends along the length direction of the rotating member 3; the groove structure 202 is arranged on the inner ring wall of the mounting portion 201; when the mounting portion 201 in an annular structure is sleeved on the rotating member 3, the protruding structure 301 and the groove structure 202 cooperate with each other. The cooperation between the protruding structure 301 and the groove structure 202 can not only ensure that the photovoltaic panel 20 rotates with the rotation of the rotating member 3, but also facilitate the installation of the mounting portion 201 on the rotating member 3 to form a guiding and positioning effect.

[0053] In one embodiment, if Fig. 9 As shown, the limiting structure may further include a positioning member 302. When the mounting portion 201 is sleeved to a predetermined height on the rotating member 3, the positioning member 302 locks the mounting portion 201 on the rotating member 3. The positioning member 302 may be a clamp structure, a latch structure, etc., which is mounted on the rotating member 3 and is located at the lower side of the mounting portion 201 to support the mounting portion 201. Alternatively, the positioning member 302 may be a bolt, a latch, etc., which passes through the mounting portion 201 and the rotating member 3 to achieve the positioning and fixation of the mounting portion 201, thereby allowing the photovoltaic panel 20 to rotate with the rotation of the rotating member 3.

[0054] In one embodiment, if Fig.10 As shown, the photovoltaic panel posture adjustment device can also include a linear displacement mechanism 5 and a connector 51, the linear displacement mechanism 5 is installed on the support frame 1 and extends along the n direction, one end of the connector 51 is installed on the linear displacement mechanism 5, and the other end of the connector 51 is slidably mounted on the rotating member 3 and supports the bottom surface of the mounting portion 201. The linear displacement mechanism 5 drives the connector 51 to move along the n direction, and then the position of the photovoltaic panel 20 on the rotating member 3 can be adjusted. It should be noted that the displacement distance of the photovoltaic panel 20 on the rotating member 3 along the n direction is limited. If the mounting portion 201 of the photovoltaic panel 20 and the rotating member 3 cooperate with each other through the protrusion structure 301 and the groove structure 202, the displacement distance of the photovoltaic panel 20 along the n direction preferably cannot exceed the extension length of the protrusion structure 301.

[0055] Furthermore, in a photovoltaic curtain wall structure, if a plurality of photovoltaic panel posture adjustment devices of the present embodiment are installed on a facade array, in order to lay as many photovoltaic panels 20 as possible within a limited installation distance, the installation distances between the photovoltaic panel posture adjustment devices are relatively compact. When the photovoltaic bracket 10 changes the angle of the photovoltaic panel 20 to achieve light chasing, partial areas of the upper and lower adjacent photovoltaic panels 20 may be blocked from each other. At this time, the spacing between the upper and lower adjacent photovoltaic panels 20 can be appropriately changed through the operation of the linear displacement mechanism 5, thereby avoiding mutual blocking.

[0056] In addition, when multiple photovoltaic panel posture adjustment devices are laid on a vertical array, in order to make the upper and lower spacings of all photovoltaic panels 20 uniform and beautiful, the linear displacement mechanism 5 can also be used to appropriately adjust the spacings between the upper and lower adjacent photovoltaic panels 20.

[0057] In one embodiment, if Figures 2 to 5 As shown, the support frame 1 may be a grid-like frame formed by a plurality of strip-shaped flat plates cross-connected horizontally and vertically.

[0058] In one embodiment, when the telescopic mechanism 2 has the shortest telescopic length, the rotation axis of the rotating member 3 is preferably parallel to the surface of the facade structure.

[0059] like Fig.11 As shown, the present application also provides a photovoltaic curtain wall system, which includes at least one of the aforementioned photovoltaic panel posture adjustment devices, and all photovoltaic panel posture adjustment devices are installed on a facade structure in an array arrangement.

[0060] In one embodiment, the photovoltaic curtain wall system may include a solar tracking sensor 30 and a main control device 40. The solar tracking sensor 30 is installed at the top of the facade structure. The main control device 40 is connected to the solar tracking sensor 30 in communication, and is connected to the telescopic mechanism 2 and the driving mechanism 4 of the photovoltaic panel posture adjustment device in communication.

[0061] Specifically, the main control device 40 obtains the sun's position through the sun tracking sensor 30, calculates the optimal posture angle of the photovoltaic panel 20, and compares it with the current posture angle of the photovoltaic panel 20 to obtain the posture angle adjustment amount of the photovoltaic panel 20; the main control device 40 converts the posture angle adjustment amount into a vertical angle modification amount and a horizontal angle modification amount, and sends corresponding signals to the telescopic mechanism 2 and the driving mechanism 4 to activate the telescopic mechanism 2 and the driving mechanism 4 to adjust the current posture angle of the photovoltaic panel 20 to the optimal posture angle, so as to better receive sunlight and improve power generation efficiency.

[0062] It can be seen that the addition of the solar tracking sensor 30 and the main control device 40 can realize the flexible tracking and timely adjustment of each photovoltaic panel 20 with the angle of the sun, so that the photovoltaic panel 20 always remains at the optimal angle, maximizes the reception of sunlight, and improves the overall power generation efficiency of the photovoltaic system.

[0063] It should be noted that the main control device 40 can obtain the sun's position in real time through the sun tracking sensor 30, and adjust the telescopic mechanism 2 and the driving mechanism 4 in real time to achieve real-time adjustment of the angle of the photovoltaic panel 20. Alternatively, the main control device 40 can obtain the sun's position through the sun tracking sensor 30 at predetermined time intervals (for example, 30 minutes, 1 hour, or 2 hours), and adjust the telescopic mechanism 2 and the driving mechanism 4 at intervals to achieve periodic adjustment of the angle of the photovoltaic panel 20.

[0064] In one embodiment, the photovoltaic curtain wall system may include a posture angle sensor (not shown in the figure) that is communicatively connected to the main control device 40. The posture angle sensor is installed on the photovoltaic panel 20 of the photovoltaic panel posture adjustment device. The main control device 40 obtains the posture angle of the photovoltaic panel 20 through the posture angle sensor to determine whether the posture angle of the photovoltaic panel 20 has been adjusted to the desired posture angle.

[0065] In one embodiment, the photovoltaic curtain wall system may include a first angle sensor (not shown in the figure) and a second angle sensor (not shown in the figure) that are communicatively connected to the main control device 40. The first angle sensor is installed on the rotating member 3 of the photovoltaic panel posture adjustment device, and the main control device 40 obtains the rotation angle of the rotating member 3 through the first angle sensor. The second angle sensor is installed on the support frame 1 of the photovoltaic panel posture adjustment device, and the main control device 40 obtains the inclination angle of the support frame 1 through the second angle sensor. At the same time, the main control device 40 can also obtain the posture angle of the photovoltaic panel 20 through the numerical values ​​of the first angle sensor and the second angle sensor, thereby confirming whether the posture angle of the photovoltaic panel 20 has been adjusted to the desired posture angle.

[0066] In one embodiment, a posture angle sensor can be installed on the photovoltaic panel 20 to confirm the posture angle of the photovoltaic panel 20. At the same time, a first angle sensor can be installed on the rotating part 3 to confirm the rotation angle of the rotating part 3, and a second angle sensor can be installed on the support frame 1 to confirm the inclination angle of the support frame 1.

[0067] The above description is only a partial embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
