In some embodiments, the adjustable photovoltaic support apparatus of the embodiment of the present invention further includes a control assembly 52, where the control assembly 52 includes at least one driving member having a driving portion, and the driving portion is configured to be connected to the fifth connecting portion 413 and the sixth connecting portion 423, so as to drive the fifth connecting portion 413 and the sixth connecting portion 423 to rotate around the second axis.
For example, when there is a driving member, the fifth connecting portion 413 and the sixth connecting portion 423 are connected to the driving portion of the driving member through a rope, and it is ensured that the rotation angles of the fifth connecting portion 413 and the sixth connecting portion 423 are consistent when they rotate. As shown in fig. 1, when the driving member is started, the rope is tightened, and the first rotating member 41 and the second rotating member 42 rotate around the first axis in the same direction to drive the second rope 22 to rotate, so that the front end of the photovoltaic panel 6 is higher than the rear end of the photovoltaic panel 6, thereby adjusting the light receiving angle of the photovoltaic panel 6.
It is understood that when the position of the second rope 22 in the up-down direction is changed, the first rope 21 is deformed and tends to return to the original position. Then, when the second driving member is turned off, the rope is released, the first rope 21 is gradually restored to the initial position, and the photovoltaic panel 6 drives the second connecting member to be restored to the initial position, so that the angle adjustment is performed next time.
For example, when there are two driving members, the output parts of the two driving members are respectively connected to the fifth connecting part 413 and the sixth connecting part 423 through ropes, and the directions and the sizes of the ropes received by the fifth connecting part 413 and the sixth connecting part 423 are equal. When the driving members are simultaneously turned on or off, the first rotating member 41 and the second rotating member 42 can be controlled to simultaneously rotate, so as to adjust the light receiving angle of the photovoltaic panel 6.
It should be noted that the driving member may be a motor, and of course, the driving member may also be a structure with a self-locking function, for example: ratchet pawl structure.
For example, the driver is formed of a ratchet pawl structure, the ratchet forming a driving portion, the driving portion being connected to the fifth connecting portion 413 and the sixth connecting portion 423 by a rope. The drive division is rotatable in one direction, then can not rotate in another direction be the lock-up state promptly, and the drive division can lock the rotation of drive division with the pawl cooperation after rotating certain angle so, that is to say, rotates the drive division to drive five connecting portion and sixth connecting portion 423 rotations through the rope, thereby make second rope 22 remove, in order to realize photovoltaic board 6 angle modulation in the second direction.
