[0041] like Figure 1 and Figure 2 As shown, this application embodiment provides a photovoltaic device 10, including:

[0042] 100 photovoltaic panels; and

[0043] A rotation adjustment assembly 400 includes a clamping member 420, a locking member 430, and a base 410. The clamping member 420 clamps the photovoltaic panel 100. The clamping member 420 is rotatably connected to the base 410 to adjust the angle of the photovoltaic panel 100 relative to the horizontal plane. The locking member 430 locks the clamping member 420 when the photovoltaic panel 100 is at a preset angle.

[0044] In the technical solution of this application embodiment, the angle of the photovoltaic panel 100 relative to the horizontal plane can be adjusted by the rotation adjustment component 400, and when the photovoltaic panel 100 is adjusted to a preset angle, the locking component 430 can lock the photovoltaic panel 100 at that preset angle, so that the photovoltaic panel 100 can fully receive sunlight and improve power generation efficiency. Specifically, in the technical solution of this application embodiment, the photovoltaic panel 100 is clamped by the clamping component 420; the clamping component 420 can rotate relative to the base 410, and its angle relative to the horizontal plane can be adjusted so that it can be adjusted to an angle that can fully utilize sunlight; when the clamping component 420 is adjusted to a preset angle relative to the base 410, the locking component 430 locks the photovoltaic panel 100.

[0045] It should be noted that this preset angle is determined based on the solar illumination conditions. For example, the user can adjust the angle relative to the horizontal plane by rotating the clamp 420, causing the photovoltaic panel 100 to rotate relative to the base 410, so that the sunlight shines on the photovoltaic panel 100 at a basically perpendicular angle, according to the current solar illumination conditions.

[0046] For example, the preset angle is determined based on the position of the obstruction. For instance, the user can adjust the angle relative to the horizontal plane by rotating the clamp 420, causing the photovoltaic panel 100 to rotate relative to the base 410, so that when the preset angle is reached, the obstruction will not block the photovoltaic panel 100.

[0047] As an optional implementation of the above embodiments, such as Figure 3 and Figure 4 As shown, the seat 410 has a mating groove S1; the mating groove S1 has an upwardly facing insertion opening S11 in the radial direction of the rotating head 421. Figure 5 and Figure 6 As shown, the clamping member 420 includes a rotating head 421. (As indicated...) Figure 2As shown, the rotating head 421 is inserted into the mating groove S1 through the insertion port S11 and rotates with the mating groove S1. The groove wall 4111 of the mating groove S1 axially positions the rotating head 421. During installation, the rotating head 421 is radially inserted into the mating groove S1 through the insertion port S11, and the rotating head 421 rotates with the mating groove S1. There is no constraint on the rotating head 421 in the rotational direction, allowing the clamping member 420 to rotate and thus adjust the tilt angle relative to the horizontal plane. Axially, the rotating head 421 is axially positioned and constrained to prevent it from sliding out of the mating groove S1. When the photovoltaic panel 100 is adjusted to a preset angle, as... Figure 2 As shown, at least a portion of the locking member 430 is embedded in the insertion port S11 and fixes the rotating head 421 in its rotation direction, and the locking member 430 abuts against the mating groove S1 on both sides of the rotating head 421 in its rotation direction. The locking member 430 is embedded in the upward-facing insertion port S11 and abuts against the mating groove S1 on both sides of the rotating head 421 in its rotation direction, such that after the locking member 430 is applied to the rotating head 421, the rotating head 421 is also constrained in its rotation direction.

[0048] Therefore, when the photovoltaic panel 100 is adjusted to a preset angle, the rotating head 421 is axially positioned via the mating groove S1. Furthermore, with the insertion port S11 facing upwards, the rotating head 421 is inserted into the mating groove S1 from top to bottom, and radially, the rotating head 421 remains stationary relative to the base 410 under its own weight. The insert is inserted into the upward-facing insertion port S11 and abuts against the mating groove S1 on both sides in the rotation direction of the rotating head 421, so that after the locking member 430 engages the rotating head 421, the rotating head 421 is also constrained in its rotation direction. Therefore, when the photovoltaic panel 100 is adjusted to a preset angle, the clamping member 420 is constrained axially, radially, and in its rotation direction.

[0049] When it is necessary to adjust the photovoltaic panel 100 from the current preset angle to another angle, the locking member 430 unlocks the rotating head and restores the degree of freedom in the rotation direction; at this time, the tilt angle of the photovoltaic panel 100 relative to the horizontal plane can be adjusted.

[0050] As an optional implementation of the above embodiments, such as Figure 5 and Figure 6 As shown, the rotating head 421 is provided with a plurality of first mating holes 4211, which are spaced apart along the rotation direction of the rotating head 421. Figure 2 and Figure 7As shown, the locking member 430 includes a locking block and a connecting member 432. The locking block has a second mating hole 431. The connecting member 432 is detachably connected to the second mating hole 431 and one of the plurality of first mating holes 4211. In an embodiment, the first mating holes 4211 are spaced apart along the direction of the rotating head 421. The locking member 430 includes a locking block and a connecting member 432. The locking block has a second mating hole 431.

[0051] The connector 432 can be a threaded part, a pin, etc. After the photovoltaic panel 100 is adjusted to a preset angle, to ensure alignment of the first mating hole 4211 and the second mating hole 431, the photovoltaic panel 100 is allowed to deviate slightly from the optimal irradiation angle. This ensures that after the locking block is inserted into the insertion port S11, the first mating hole 4211 and the second mating hole 431 are aligned. At this point, the connector 432 is connected to the first mating hole 4211 and the second mating hole 431. During disassembly, the constraint of the connector 432 on the first mating hole 4211 and the second mating hole 431 is released.

[0052] As an optional implementation of the above embodiments, such as Figure 5 As shown, the clamping member 420 further includes a clamping seat 422 and a transition connector 423; the rotating head 421 is connected to the clamping seat 422 through the transition connector 423. In an embodiment, the clamping seat 422, the transition connector 423, and the rotating head 421 of the clamping member 420 can be integrally formed, for example, they can be manufactured by milling or other machining processes on a metal part. The seat body 410 includes a limiting body 411, one side of which is the groove wall 4111; the limiting body 411 has a relief groove S2, which communicates with the mating groove S1; the transition connector 423 is embedded in the relief groove S2 and can rotate within the relief groove S2. In the embodiment, the limiting body 411 axially positions the rotating head 421, and the limiting body 411 is provided with a relief groove S2. The relief groove S2 is rotated and fitted with a transition connector 423, so that the clamping seat 422 can extend out of the seat body 410 to clamp the photovoltaic panel 100.

[0053] In one embodiment, the clamping member 420 further includes a clamping hand 424, which is detachably connected to the clamping base 422. The clamping hand 424 clamps the photovoltaic panel 100. The clamping hand 424 can be fixed to the clamping base 422 by a threaded connection.

[0054] As an optional implementation of the above embodiments, the photovoltaic device 10 further includes a support assembly 200; the support assembly 200 is provided with at least two rotation adjustment assemblies 400, and the rotation adjustment assemblies 400 are movable in the length direction of the support assembly 200; wherein, the clamping members 420 of two adjacent rotation adjustment assemblies 400 clamp the same photovoltaic panel 100 on both sides in the length direction. In the embodiments, by adjusting the spacing between two adjacent rotation adjustment assemblies 400, photovoltaic panels 100 of different specifications can be clamped. Figure 1 As shown, two rotation adjustment components 400 are slidably provided on the support component 200. In some other embodiments, two or more rotation adjustment components 400 may also be provided on the support component 200.

[0055] As an optional implementation of the above embodiments, the photovoltaic device 10 includes at least two of the aforementioned support components 200. Adjacent support components 200 are foldable. Figure 8 As shown, the photovoltaic device 10 includes three support components 200. Two adjacent support components 200 are configured to be foldable for storage when not in use.

[0056] Reference Figure 8 and Figure 9 As shown, the first support base 201 and the second support base 202 of two adjacent support components 200 are connected by a folding shaft 600. Figure 9 In this configuration, the folding shaft 600 is horizontally oriented. The folding shaft 600 is fixed to the first support 201, and the second support 202 has a shaft hole that mates with the folding shaft 600. The folding shaft 600 is rotatably engaged with the shaft hole, and a nut positions the folding shaft 600 axially. In some embodiments, the first support 201 and the second support 202 are further provided with latches. The latches include a connecting rod 702 and a wrench 701. Both ends of the connecting rod 702 are rotatably connected to the wrench 701 and the first support 201, respectively. The wrench 701 is also rotatably connected to the second support 202. The latches allow the first support 201 and the second support 202 to be folded and stored.

In other embodiments, the seat 410 is sleeved on the support rod 440, and the seat 410 can move relative to the support rod 440 in the height direction; after the seat 410 has moved to a certain height, the seat 410 and the support rod 440 can be locked by a threaded component.
