Description

Technical Field

[0001] The present invention relates to the field of photovoltaic equipment, and in particular to a photovoltaic device. Background Art

[0002] Photovoltaic systems can convert light energy into electrical energy. Photovoltaic modules usually need to be installed in a location where they can be exposed to sunlight to receive light energy. Photovoltaic systems include photovoltaic modules and mounting brackets for photovoltaic module installation.

[0003] Most of the current mounting brackets are fixed brackets, which cannot adjust the tilt angle (abbreviated as tilt angle) of the photovoltaic module. The photovoltaic module is installed by a fixed bracket and can only be placed at a fixed tilt angle. However, the angle of direct sunlight is different at different times of the day. The installation of fixed brackets cannot adjust the optimal tilt angle of the photovoltaic module at different times, which is not conducive to optimizing the power generation capacity of the photovoltaic module. Especially in relatively narrow installation places such as balconies, if the tilt angle of the photovoltaic module cannot be adjusted, it may cause the photovoltaic module to receive less or even no light energy.

[0004] A small number of current mounting brackets are brackets with manually adjustable inclination angles, but the means for adjusting the inclination angles are cumbersome and the process is complicated, and the inclination angle adjustment of the photovoltaic module cannot be quickly achieved. Summary of the invention

[0005] The purpose of the present invention is at least to provide a photovoltaic device that can conveniently adjust the inclination angle of photovoltaic modules, so that the photovoltaic modules can be at the optimal power generation angle in different time periods, thereby improving the power generation efficiency of the photovoltaic modules.

[0033] In some embodiments, Figure 3 As shown, both ends of the rotating shaft 122 are sleeved on the first end of the supporting frame 121. In some embodiments, a tube support 1211 is provided on the first end of the supporting frame 121. The tube support 1211 is a sleeve structure. Both ends of the rotating shaft 122 are sleeved in the tube support 1211 to achieve the fixation of the rotating shaft 122 and the first end of the supporting frame 121. In some embodiments, a hook 1111 is provided on the first side 111 of the photovoltaic module 110, such as Figure 2 and Figure 3As shown, a bayonet is provided on the hook 1111, and the bayonet is an open structure. The hook 1111 is inserted into the rotating shaft 122 through the bayonet, and the hook 1111 can rotate relative to the rotating shaft 122, so as to realize the rotatable connection between the photovoltaic component 110 and the rotating shaft 122. In some embodiments, the first end of the hook 1111 is fixed to the first side 111 of the photovoltaic component 110, and the second end of the hook 1111 is an arc structure. In this case, the hook 1111 is an arc hook, and the two ends of the arc hook extending along the arc are close to each other to form an open bayonet. The rotating shaft 122 is a circular rotating shaft, and the rotating shaft 122 is a circular columnar structure as a whole. The arc hook is inserted into the rotating shaft 122 through its bayonet, that is, the arc hook is surrounded by the outside of the rotating shaft 122, and can rotate relative to the rotating shaft 122, so as to realize the rotatable connection between the photovoltaic component 110 and the supporting frame 121.

[0034] In some embodiments, the adjustment assembly 123 includes an adjustment wrench 1231, which is disposed on the first side 111 of the photovoltaic assembly 110. The photovoltaic assembly 110 can be rotated around the rotating shaft 122 by turning the adjustment wrench 1231 counterclockwise or clockwise. In some embodiments, the first end of the adjustment wrench 1231 extends outward from the photovoltaic assembly 110 to facilitate the operation of the adjustment wrench 1231, and the second end of the adjustment wrench 1231 is connected to the photovoltaic assembly 110. In some embodiments, in order to facilitate the connection between the adjustment wrench 1231 and the existing photovoltaic assembly 110, a side extension structure is provided at the second end of the adjustment wrench 1231 to cooperate with the notch of the side 112 of the existing photovoltaic assembly 110, and the side extension structure can be extended into the notch of the side 112 of the photovoltaic assembly 110 to achieve a snap connection.

[0035] In some embodiments of the present specification, by setting the support frame 121 and the adjustment component 123 to cooperate with the relevant structures of the existing photovoltaic component 110 (such as the first side 111 and the side 112), the support frame 121 and the adjustment component 123 can be quickly installed and disassembled from the existing photovoltaic component 110, so as to facilitate the modification of the photovoltaic component 110 on the basis of the existing photovoltaic component 110 and the adjustment of the inclination angle of the existing photovoltaic component 110.

[0036] Figure 4 is a side view of an adjusting wrench according to some embodiments.

[0037] In some embodiments, Figure 4As shown, to facilitate the operation of the adjusting wrench 1231, the adjusting wrench 1231 cooperates with the rotating shaft 122. When the adjusting wrench 1231 is turned, the rotating shaft 122 is used as a force application point to drive the photovoltaic assembly 110 to rotate around the rotating shaft 122. In some embodiments, a semicircular groove is provided on the side of the adjusting wrench 1231 close to the rotating shaft 122, and the semicircular groove is engaged with the circular rotating shaft 122. The semicircular groove can rotate relative to the circular rotating shaft 122. By turning the first end of the adjusting wrench 1231 counterclockwise or clockwise, the semicircular groove on the adjusting wrench 1231 rotates relative to the circular rotating shaft 122, and the photovoltaic assembly 110 is driven to rotate around the rotating shaft 122.

[0038] In some embodiments, to ensure the stability of the photovoltaic assembly 110 during the tilt adjustment process, the adjustment assembly 123 further includes a slide rail 1232 and a support rod 1233 .

[0039] In some embodiments, the slide rail 1232 is fixedly installed relative to the support frame 121. In some embodiments, the slide rail 1232 is vertically arranged relative to the installation plane of the photovoltaic module 110. The inclination angle of the photovoltaic module 110 described in this specification refers to the angle β between the panel of the photovoltaic module 110 and the slide rail 1232. In some embodiments, in order to realize the quick disassembly and installation of the slide rail 1232 relative to the support frame 121, a plug plate 12321 is provided on the slide rail 1232, a slot is provided on the plug plate 12321, and a hanging rod 1211 is provided on the support frame 121. The slot extends in a direction perpendicular to the installation plane (hereinafter referred to as the vertical direction), and the slot is inserted into the hanging rod 1211 in the vertical direction, and the slide rail 1232 is hung on the support frame 121 to realize the installation of the slide rail 1232.

[0040] In some embodiments, the first end of the support rod 1233 is hinged to the side 112 of the photovoltaic assembly 110, and the second end of the support rod 1233 is slidably connected to the slide rail 1232. The adjustment wrench 1231 is turned to drive the photovoltaic assembly 110 to rotate around the rotation axis 122. The rotation of the photovoltaic assembly 110 drives the second end of the support rod 1233 to slide on the slide rail 1232. The second end of the support rod slides relative to the slide rail to adjust the inclination angle of the photovoltaic assembly 110 relative to the slide rail 1232. The support rod 1233 supports the sliding of the photovoltaic assembly 110, which can ensure the structural stability of the photovoltaic assembly 110 during the inclination adjustment process.

[0041] In some embodiments, a first slider is disposed on the second end of the support rod 1233 (the first slider and the second slider described below are disposed on the second end of the support rod 1233). Figure 2The first slider is uniformly marked as slider 1234 in the figure, and the first slider is slidably matched with the slide rail 1232. The second end of the support rod 1233 is hinged to the first slider. In some embodiments, a slide groove is provided on the slide rail 1232, and the first slider is embedded in the slide groove and can slide relative to the slide groove. In some embodiments, in order to reduce the sliding friction between the first slider and the slide rail 1232, the first slider is a rolling wheel, which rolls in the slide groove provided on the slide rail 1232.

[0042] In some embodiments, a plurality of first locking holes are arranged on the slide rail 1232 along the sliding direction of the first slider. The sliding direction of the first slider is consistent with the vertical direction. Figure 2 In the figure, the first locking hole 1235 is uniformly marked as a locking hole 1235. In some embodiments, the first locking hole is set on the side wall of the slide rail 1232, and the first locking hole passes through the side wall of the slide rail 1232, and a threaded hole is correspondingly set on the first slider. When the threaded hole on the first slider slides to align with the first locking hole, the bolt passes through the first locking hole and the threaded hole in turn, and is threadedly connected with the threaded hole to achieve a fastened connection between the first slider and the slide rail 1232, thereby achieving fastening between the support rod 1233 and the slide rail 1232, ensuring the structural stability and normal operation of the photovoltaic module 110 after the inclination adjustment is completed.

[0043] In some embodiments, a commonly used inclination angle of the photovoltaic assembly 110 is set corresponding to the solar radiation angle in different time periods. The commonly used inclination angles include 0°, 45°, 60°, and 80°. Figure 5 1 is a schematic diagram of the structure of the slide rail according to some embodiments. In some embodiments, the position of the first locking hole on the slide rail 1232 is determined corresponding to the commonly used inclination angle. Figure 5 As shown, the multiple first locking holes arranged in sequence from bottom to top along the vertical direction on the slide rail 1232 correspond to the commonly used inclination angles of 0°, 45°, 60°, and 80°, respectively. That is to say, when the first slider slides from bottom to top along the vertical direction to the first locking hole and is fastened with the first locking hole, the inclination angle of the photovoltaic module 110 is adjusted to 0°, 45°, 60°, and 80°, respectively. It should be noted that the relevant settings of the first locking hole, including the number and position, can be adjusted according to actual conditions.

[0044] In some embodiments, in order to enhance the stability of the photovoltaic assembly 110 during the tilt adjustment process, the adjustment assembly 123 further includes an auxiliary support rod 1237, the first end of the auxiliary support rod 1237 is hinged to the support rod 1233, and the second end of the auxiliary support rod 1237 is slidably connected to the slide rail. By pulling the adjustment wrench 1231, the photovoltaic assembly 110 is driven to rotate around the rotating shaft 122. The rotation of the photovoltaic assembly 110 drives the second end of the support rod 1233 and the second end of the auxiliary support rod 1237 to slide on the slide rail 1232. The support rod 1233 and the auxiliary support rod 1237 provide sliding support for the photovoltaic assembly 110, which can further ensure the structural stability of the photovoltaic assembly 110 during the tilt adjustment process.

[0045] In some embodiments, the first end of the auxiliary support rod 1237 is hinged to the middle of the support rod 1233. In some embodiments, a second slider is provided on the second end of the auxiliary support rod 1237, and the second slider is slidably matched with the slide rail 1232. The relevant configuration of the second slider is similar to that of the first slider, and the relevant configuration of the second slider refers to the description of the first slider.

[0046] In some embodiments, a plurality of second locking holes are arranged at intervals along the sliding direction of the second slider on the slide rail 1232. The sliding direction of the second slider here is consistent with the sliding direction of the first slider. In some embodiments, the second locking hole is arranged on the side wall of the slide rail 1232, and the second locking hole penetrates the side wall of the slide rail 1232, and a threaded hole is correspondingly arranged on the second slider. When the threaded hole on the second slider slides to align with the second locking hole, the bolt passes through the second locking hole and the threaded hole in turn, and is threadedly connected with the threaded hole to achieve a fastened connection between the second slider and the slide rail 1232, thereby achieving fastening between the auxiliary support rod 1237 and the slide rail 1232, and ensuring the structural stability and normal operation of the photovoltaic module 110 after the inclination adjustment is completed.

[0047] In some embodiments, corresponding to commonly used inclination angles including 0°, 45°, 60°, and 80°, a plurality of first locking holes are provided on the slide rail 1232 from bottom to top along the vertical direction. Corresponding to the positions of the first locking holes, a plurality of second locking holes are provided on the slide rail 1232 from bottom to top along the vertical direction. Specifically, Figure 5 As shown, locking hole 51 is the first locking hole and the second locking hole corresponding to a 0° inclination angle; locking hole 52 is the first locking hole and the second locking hole corresponding to a 45° inclination angle; locking hole 53 is the first locking hole and the second locking hole corresponding to a 60° inclination angle; locking hole 54 is the first locking hole and the second locking hole corresponding to an 80° inclination angle. In some embodiments, the angle between the auxiliary support rod 1237 and the support rod 1233 is adjustable. Figure 5As shown, according to different inclination angles, the distance between the first locking hole and the second locking hole is set accordingly to adjust the angle between the auxiliary strut 1237 and the strut 1233, that is, when the inclination angles are different, the distance between the corresponding first locking hole and the second locking hole is different. In some embodiments, when the inclination angle is smaller, the distance between the corresponding first locking hole and the second locking hole is larger, so that the angle between the auxiliary strut 1237 and the strut 1233 is larger. When the inclination angle is larger, the distance between the corresponding first locking hole and the second locking hole is smaller, so that the angle between the auxiliary strut 1237 and the strut 1233 is smaller. The inclination angle is different, and the force between the photovoltaic assembly 110 and the adjustment assembly 123 is different. According to the adjustment of the inclination angle, the angle between the auxiliary strut 1237 and the strut 1233 is adjusted to adapt to the force conditions of the photovoltaic assembly 110 at different inclination angles, and ensure the structural stability of the photovoltaic assembly 110 during the inclination adjustment process.
