According to an embodiment of the present invention, referring to fig. 1 to 11, a solar rack may specifically include a rack structure 100, a solar panel, a plurality of rotating mechanisms and a driving device 400. The frame structure 100 includes a fixing portion 110 and a rotating mechanism 120 disposed at a top end of the fixing portion 110, and the solar panel is mounted on the rotating mechanism 120 of the frame structure 100. The plurality of rotating mechanisms are sequentially mounted on the supporting structure 100 and comprise a first rotating member 200 and a second rotating member 300 which are in transmission connection. The driving device 400 includes a driving element 410 and a main rope 420, at least one main rope 420 is orderly connected to the first rotating element 200, the driving element 410 is connected to the main rope 420, the main rope 420 drives the first rotating element 200 to rotate under the action of the driving element 410, so as to drive the second rotating element 300 to rotate, and further drive the rotating mechanism 120 to rotate, so as to adjust the angle of the solar panel.

It should be noted that the angular velocity of the second rotating member 300 should be greater than that of the rotating mechanism 120, and the radius of rotation of the first rotating member 200 is greater than that of the second rotating member 300.

Generally speaking, in this embodiment, the linear velocities of the second rotating component 300 and the rotating component 120 are the same, and at this time, the angular velocity of the second rotating component 300 is greater than the angular velocity of the rotating component 120, so that when the output shaft of the driving component 410 drives the second rotating component 300 to rotate for one circle, the rotating angle of the rotating component 120 does not reach one circle, even only a small angle is tilted, so that the rotating component 120 and the solar panel can more stably rotate along with the second rotating component 300, and the stability of the whole photovoltaic system is improved. Meanwhile, the driving member 410 can adjust the rotation angle of the rotating mechanism 120 more precisely, so that the solar panel is adjusted to the most suitable position, and the power generation efficiency is high.

In addition, the rotation radius of the first rotating member 200 is larger than that of the second rotating member 300, so that the load on the whole solar rack is more applied to the fixing portion 110, the pulling force on the main rope 420 is reduced, and the load on the driving device 400 is reduced, so that the whole photovoltaic system is more uniformly stressed, has better wind resistance and is higher in safety.

In addition, when the tension applied to the main rope 420 is reduced, the amount of expansion and contraction of the length thereof is reduced, and the transmission is more stable. Meanwhile, under the condition that the lengths of the main ropes 420 are the same, compared with the solar supports used in the prior art, the solar supports provided by the embodiment have smaller angle deviation of the solar panels on the solar supports, so that the transmission distance of the main ropes 420 can be greatly increased under the requirement of acceptable angle deviation, the installed capacity of the system is greatly improved, the total generated energy is improved, and the economic benefit is high.

In addition, the main rope 420 can greatly reduce the type selection requirement of the main rope 420 due to the reduction of the tension of the main rope 420, so that the material cost of the main rope 420 is reduced, and the economic benefit is higher.

Specifically, in the present embodiment, two main ropes 420 are commonly provided, and are respectively disposed on two opposite sides of the driving element 410 and extend in a direction away from each other, and at this time, each main rope 420 can be respectively connected to at least one first rotating element 200.

Alternatively, referring to fig. 10, two first rotating members 200 are fixed to each of the fixing portions 110. At this time, the number of the main ropes 420 is two, the two main ropes 420 are respectively disposed on two opposite sides of the driving member 410 and extend in the same direction, and the two main ropes 420 are respectively connected to the two first rotating members 200 disposed on the at least one fixing portion 110.

Alternatively, referring to fig. 11, the number of the main ropes 420 is one, and the main ropes are directly sleeved on the first rotating members 200 arranged on the same straight line.

Alternatively, the first rotating member 200 is a reel, and the outer side wall of the reel is wound with the auxiliary ropes, and the number of the auxiliary ropes may be one or two. If the number of the auxiliary ropes is one, the middle section of the auxiliary rope is wound around the first rotating member 200 and is locked by the buckle, and both ends of the auxiliary rope are fixed to different parts of the main rope 420. At this time, the driving member 410 drives the auxiliary rope and the first rotating member 200 to rotate through the main rope 420. If the number of the auxiliary ropes is two, one ends of the two auxiliary ropes are wound around the first rotating member 200 and are fastened by the buckles, and the other ends of the two auxiliary ropes are respectively fixed to different parts of the main rope 420. In contrast, the driving member 410 drives the auxiliary rope and the first rotating member 200 to rotate through the main rope 420.

It can be seen that the number of the main ropes 420 and the arrangement of the main ropes 420 and the first rotating member 200 can be varied, and the above-mentioned embodiments are only some examples, which are not limited herein, and are within the protection scope of the present invention.

Preferably, the driver 410 is a worm gear reducer. Generally, when the solar panel is affected by high wind, the solar panel will shake greatly, so as to drive the rotating mechanism 120 and the second rotating member 300 to rotate, and further drive the first rotating member 200 to rotate. The worm gear reducer has a self-locking function, and can limit the first rotating part 200 to rotate under the driving of the second rotating part 300 to a certain extent, so as to limit the rotation of the second rotating part 300 and the rotating mechanism 120, and enable the solar panel to be still in a stable state under the action of wind power.

Specifically, referring to fig. 1 to 6, the first rotating member 200 is in transmission connection with the second rotating member 300 through a shaft 500, and at this time, the first rotating member 200 drives the second rotating member 300 to rotate synchronously under the action of the main rope 420. In this case, the first rotating member 200 and the second rotating member 300 are generally disposed at the position above the fixed portion 110, but if the second rotating member 300 is a roller wound with the transmission rope 310 and the two ends of the transmission rope 310 are fixed at different positions of the rotating mechanism 120, the first rotating member 200 and the second rotating member 300 can be disposed at the position below the fixed portion 110, so that the stability is better.

In practical production, referring to fig. 7 to 9, the first rotating member 200 can also be in transmission connection with the second rotating member 300 through the transmission member 600, and at this time, the first rotating member 200 drives the transmission member 600 to work under the action of the main rope 420, so as to drive the second rotating member 300 to rotate. In this case, the first rotating member 200 is generally disposed at a position lower than the fixed portion 110, and stability is good. The transmission member 600 may be two synchronous pulleys (or drums) that rotate synchronously with the first rotating member 200 and the second rotating member 300, and the second rotating member 300 is driven by the first rotating member 200 and the transmission member 600 to rotate through a set of synchronous belts (or transmission ropes 310) provided on the two synchronous pulleys (or drums). In addition, the transmission member 600 may also be a connecting rod, and two ends of the connecting rod are respectively fixed at the eccentric positions of the first rotating member 200 and the second rotating member 300, so that the second rotating member 300 is driven by the first rotating member 200 and the transmission member 600 to rotate. Of course, the transmission member 600 may have other structures, and it is sufficient to realize the transmission connection between the first rotating member 200 and the second rotating member 300, and this embodiment only illustrates some possible embodiments, and is not limited herein, and is within the protection scope of the present invention.

In the above two embodiments, the shaft 500 or the transmission member 600 may drivingly connect one first rotating member 200 and one second rotating member 300. At this time, the mass of the first rotating member 200 should be greater than 10kg, so that it has a large inertia, increasing the kinetic energy conversion of the rotating mechanism 120. Thus, when the rotating mechanism 120 is inclined to drive the second rotating member 300 and the first rotating member 200 to rotate due to the wind force, the first rotating member 200 has a larger inertia and is not easily driven by the rotating mechanism 120, thereby improving the wind resistance of the solar rack to a certain extent.

Of course, the shaft 500 or the transmission member 600 may also drivingly connect the two first rotating members 200 and the one second rotating member 300. In which the shaft 500 drivingly connects two first rotating members 200 and one second rotating member 300, refer to the example shown in fig. 10 in which two first rotating members 200 are fixed to each fixed portion 110. At this time, the total mass of the two first rotating members 200 should be greater than 10kg, so that the two first rotating members 200 have larger inertia, thereby increasing the kinetic energy conversion of the rotating mechanism 120. Thus, when the rotating mechanism 120 is inclined to drive the second rotating member 300 and the first rotating member 200 to rotate due to the wind force, the first rotating member 200 has a larger inertia and is not easily driven by the rotating mechanism 120, thereby improving the wind resistance of the solar rack to a certain extent.

In one embodiment, referring to fig. 1 and 8 to 10, the second rotating member 300 is a drum, and the driving rope 310 is wound around the outer sidewall of the drum. The driving string 310 is separated from the two ends of the second rotating member 300 and fixed to different portions of the rotating mechanism 120.

Thus, when the second rotating member 300 is driven by the first rotating member 200 to rotate, the transmission rope 310 is separated from one end of the second rotating member 300 to extend, and the other end of the second rotating member is retracted, so as to drive the rotating mechanism 120 to rotate, thereby completing the angle adjustment of the solar panel, enabling the solar panel to be directly opposite to sunlight, and greatly improving the power generation efficiency and the power generation amount.

Specifically, if the number of the transmission rope 310 is one, the middle section of the transmission rope 310 is wound around the second rotating member 300 and is locked by the fastener, and the two ends of the transmission rope are fixed to different positions of the rotating mechanism 120 after crossing. If the number of the transmission ropes 310 is two, one ends of the two transmission ropes 310 are wound around the second rotating member 300 and are locked by the fasteners, and the other ends of the two transmission ropes 310 are crossed and then fixed to different positions of the rotating mechanism 120.

Preferably, referring to fig. 1 and 8 to 10, the rotating mechanism 120 is partially configured in a circular arc shape and is provided with a wire accommodating groove 121. The two ends of the driving rope 310 separated from the second rotating member 300 are respectively fixed to the two ends of the wire accommodating groove 121 in the rotating direction of the rotating mechanism 120.

In this embodiment, since the rotating mechanism 120 is partially arc-shaped, the extension amount of the driving rope 310 separated from one end of the second rotating member 300 is substantially equal to the contraction amount of the other end of the second rotating member during the rotation of the rotating mechanism 120, so that the rotation of the solar panel is more stable, and the driving stability is higher.

In addition, the transmission rope 310 is separated from the two ends of the second rotating part 300 and is respectively fixed at the two ends of the line accommodating groove 121 in the rotating direction of the rotating mechanism 120, so that the transmission rope 310 can more easily drive the rotating mechanism 120 to rotate, and thus, under the same angle deflection, the pulling force received by the transmission rope 310 and the main rope 420 can be reduced, the transmission is more stable, and moreover, the angle deviation of the solar panel on each solar support can also be properly reduced, the total power generation amount is further improved, and the economic benefit is higher.

Specifically, referring to fig. 8 and 9, the rotation axis of the second rotating member 300 is parallel to the rotation plane of the rotating mechanism 120, and two steering wheels 111 are disposed between the second rotating member 300 and the rotating mechanism 120. The two steering wheels 111 have a gap therebetween, and the driving rope 310 is separated from both ends of the second rotating member 300 and passes through the gap. At this time, the driving rope 310 is partially accommodated in the wire accommodating groove 121 by the two steering wheels 111, and is attached to the portion of the rotating mechanism 120 having the arc-shaped structure.

In general, if the rotation axis of the second rotating member 300 is perpendicular to the rotation plane of the rotating mechanism 120, when the rotating mechanism 120 is partially formed in a circular arc shape and is engaged with the second rotating member 300, the driving string 310 is separated from one end of the second rotating member 300 by an amount equal to the amount of contraction of the other end. However, when the rotation axis of the second rotating member 300 is parallel to the rotating mechanism 120, the extension amount of the driving string 310 separated from one end of the second rotating member 300 may be deviated from the contraction amount of the other end.

In this regard, when the rotation axis of the second rotating member 300 is parallel to the rotating mechanism 120, two steering wheels 111 are required to be disposed, so that in this case, the extension amount of the transmission rope 310 separated from one end of the second rotating member 300 can be equal to the contraction amount of the other end, thereby ensuring the stable rotation and transmission stability of the solar panel. In addition, this embodiment is through setting up two directive wheel 111 for driving rope 310 can partially laminate in rotary mechanism 120, and so, driving rope 310 is more difficult because of receiving the wind-force effect and tremble, and driving rope 310 is at rotary mechanism 120 pivoted in-process, also difficult emergence is twined, has further improved driven stability.

Of course, in practical production, when the rotation axis of the second rotating member 300 is perpendicular to the rotation plane of the rotating mechanism 120, two steering wheels 111 may be provided between the second rotating member 300 and the rotating mechanism 120. At this time, the two steering wheels 111 can also make the transmission rope 310 partially fit to the rotating mechanism 120, so that the transmission rope 310 is less prone to shaking due to wind, and the transmission rope 310 is less prone to winding in the rotating process of the rotating mechanism 120, thereby further improving the stability of transmission.

In one embodiment, the rotating mechanism 120 includes a rod and a compensation wheel disposed below the rod. At this time, the driving rope 310 is separated from both ends of the second rotating member 300 and is fixed to both ends of the rod respectively to drive the rod to rotate, and the compensation wheel is used to make the elongation of one end of the driving rope 310 separated from the second rotating member 300 equal to the contraction of the other end.

In one embodiment, referring to fig. 2, the second rotating member 300 is a gear, and the rotating mechanism 120 is partially configured in a circular arc shape and is provided with a plurality of teeth 122 capable of meshing with the gear.

At this time, when the second rotating member 300 is driven by the first rotating member 200 to rotate, the second rotating member 300 drives the rotating mechanism 120 to rotate through the meshing transmission between the gear and the tooth block 122, so as to complete the angle adjustment of the solar panel, so that the solar panel can be directly opposite to the sunlight, and the power generation efficiency and the power generation amount are greatly improved.

In one embodiment, referring to fig. 3 to 7, the second rotating member 300 includes two fixed plates 320 disposed opposite to each other and two supporting rods 330 disposed between the two fixed plates 320. At this time, the rotating mechanism 120 is partially formed in a circular arc shape and has a plurality of grooves 123 that can be selectively engaged with the pillars 330.

The two support posts 330 are distributed in a central symmetry manner, and when the connecting line of the two support posts 330 is distributed along the horizontal direction, the two support posts 330 are respectively clamped in the two adjacent grooves 123. At this time, if the fixture block formed between two adjacent grooves 123 tends to drive the supporting columns 330 to rotate, since the rotating arm of the force applied by the fixture block on the supporting columns 330 is almost zero, the two supporting columns 330 can be directly clamped to form self-locking, so as to limit the second rotating member 300 from rotating under the driving of the rotating mechanism 120, thereby limiting the rotation of the rotating mechanism 120, and enabling the solar panel to be in a stable state under the action of wind. Correspondingly, at this time, the support 330 can still drive the rotation mechanism 120 to rotate, because the force applied by the support 330 to the fixture is greater than zero. So, this embodiment can also guarantee that solar panel and rotary mechanism 120 smoothly follow the second and rotate 300 rotation when avoiding solar panel to rock because of receiving the wind-force effect.

In the above embodiments, the fixing portion 110 is a column, and the top end of the column is provided with a bearing 801. At this time, the plurality of fixing portions 110 are arranged along a straight line, and a main beam 802 is rotatably inserted through the bearings 801 disposed on the plurality of fixing portions 110 in sequence, so as to form the rotating mechanism 120. Wherein, be equipped with a plurality of evenly spaced distribution's purlin on the girder 802 in proper order to fixed solar panel.

Further, the number of the main beams 802 is plural, a plurality of fixing portions 110 arranged along the length direction of one main beam 802 is defined as a row, and a plurality of fixing portions 110 arranged along a line perpendicular to the length direction of the main beam 802 is defined as a row. At this time, the whole photovoltaic system is composed of the fixing portions 110 arranged in multiple rows and multiple columns, or the fixing portions 110 arranged in multiple columns and multiple columns.

If one driving member 410 drives a row of solar panels to rotate, the second rotating member 300 can only adopt the structure arrangement including the body 310 and the driving string 310 provided in the above-mentioned embodiments. At this time, the rotation axis of the second rotating member 300 is perpendicular to the length direction of the main beam 802, and the rotation axis of the first rotating member 200 is also perpendicular to the length direction of the main beam 802, and is in transmission connection with the second rotating member 300 through the fixed shaft 500 or the transmission member 600.

If one driving member 410 drives a row of solar panels to rotate, the second rotating member 300 can be the second rotating member 300 provided in any one of the above embodiments.

It should be noted that at least one rotating mechanism and driving device 400 is disposed on the fixing portion 110 of one row or one column to ensure that the rotating mechanism 120 on the supporting structure 100 can drive the solar panel to rotate.

Preferably, the solar rack further comprises at least one damping mechanism 700. When the rotating mechanism 120 drives the rotating mechanism to work under the action of wind, the rotating mechanism drives the damping mechanism 700 to work so as to limit the rotating speed of the rotating mechanism 120, so that the whole solar bracket can better adapt to severe weather such as high wind, the situation that the solar panel shakes due to the influence of high wind, the main rope 420 is driven to swing violently is avoided, and the stability of the whole photovoltaic system is improved.

Specifically, the damping mechanism 700 includes at least one damping member 710 and a crank 720 for connecting the first rotating member 200 and the damping member 710. The crank 720 has one end fixedly connected to the first rotating member 200 and the other end rotatably connected to the damping member 710.

When the rotating mechanism 120 drives the second rotating member 300 to operate, the second rotating member 300 drives the first rotating member 200 to operate, and the first rotating member 200 further drives the damping member 710 to operate, so as to limit the rotating speed of the rotating mechanism 120.

The present embodiment increases the distance between the end of the damping member 710 connected to the first rotating member 200 and the rotation center of the transmission member and the rotation radius of the end of the damping member 710 connected to the transmission member by providing the crank 720.

Specifically, the number of the damping members 710 is two, and a predetermined included angle is formed between the two damping members 710, so that during the rotation of the first rotating member 200, the length extending direction of at least one damping member 710 is not collinear with the length extending direction of the crank 720. The arrangement can avoid the situation that the damping part 710 is blocked or even dead when in operation, and ensure that the damping part 710 can provide proper resistance for the first rotating part 200 when the first rotating part 200 rotates to any angle, thereby avoiding the situation that the damping part 710 fails to cause severe shaking of the solar panel and damage the support.

Specifically, the two damping members 710 are respectively disposed on two opposite sides of the first rotating member 200, or two first rotating members 200 are respectively disposed on two ends of the second rotating member 300 through a fixed shaft 500, and then the two damping members 710 are respectively connected to the two first rotating members 200.

Of course, in practical production, the number of the damping members 710 may also be three, four or even more, and in this case, several damping members 710 may be disposed on the same side of the same first rotating member 200, and the number of the damping members 710 may satisfy: during the rotation of the first rotating member 200, at least one damping member 710 has a length extending direction that is not collinear with the length extending direction of the crank 720.

In addition to the above situations, the number and arrangement of the damping members 710 may also be set in other various manners, which should be flexibly selected according to the actual situation, and during the rotation of the first rotating member 200, it is only required to ensure that the length extending direction of at least one damping member 710 is not collinear with the length extending direction of the crank 720, which is not repeated herein, and is within the protection scope of the present invention.

Specifically, the damping mechanism 700 further includes a mounting bracket 730, and the mounting bracket 730 is fixed to the fixed portion 110, so as to rotatably fix an end of the damping member 710 away from the first rotating member 200 to the fixed portion 110.

Of course, the mounting bracket 730 can also be separately installed on the ground, and it is sufficient that the end of the damping member 710 far from the first rotating member 200 can be rotatably fixed, and this is not limited to this, and it is within the scope of the present invention.

In addition, in practical production, the damping member 710 can also be rotatably connected to the second rotating member 300 or the rotating mechanism 120, which is not described herein again and is within the protection scope of the present invention.

In the above embodiments, the descriptions of the respective embodiments have respective emphasis, and reference may be made to the related descriptions of other embodiments for parts that are not described or recited in detail in a certain embodiment.

It should be noted that the above embodiments can be freely combined as necessary. The foregoing is only a preferred embodiment of the present invention, and it should be noted that it is obvious to those skilled in the art that various modifications and improvements can be made without departing from the principle of the present invention, and these modifications and improvements should also be considered as the protection scope of the present invention.
