In order to effectively increase the annual power generation of photovoltaic power plants, the photovoltaic module tracking system has been favored by large-scale photovoltaic power plant projects. The photovoltaic module tracking system adjusts the orientation of the photovoltaic modules mounted on it so that the photovoltaic modules are always facing the sun, so as to obtain the maximum amount of radiation and improve the power generation efficiency of the entire photovoltaic power plant.

Among them, the drive unit mainly includes a rotary reduction motor, an electric push cylinder, etc. The drive unit is directly and rigidly connected to the rotary actuator of the tracking bracket to provide power for tracking. However, when a strong wind occurs, the above drive unit will be directly hit by the impact of continuously changing direction, without any buffer, and it is easy to reduce the life of the drive unit; and, in order to resist strong winds, the above flat single-axis photovoltaic tracking bracket needs to strengthen the structural strength, such as Choose higher-strength materials, reinforced material thickness and size, etc., which not only increases the cost, but also increases the installation difficulty; in addition, the above drive unit must be erected near the same level as the torque beam, which causes When the photovoltaic tracking bracket is high, the drive unit also needs to be built very high, which is easy to be restricted by the geographical location of the site, which increases the difficulty of installation and operation and maintenance work.
因此,有必要提供一种新的用于光伏组件的跟踪系统。Therefore, it is necessary to provide a new tracking system for photovoltaic modules.

Here, two rollers 66 are provided, and the two rollers 66 respectively abut on both side surfaces of the actuating rod 3 in the second direction. When the traction mechanism 4 drives the slider 6 to move in the second direction, the driving end 32 of the actuating rod 3 moves accordingly, and the swing block 65 rotates at an angle relative to the base 61, so that the When the actuating rod 3 moves relative to the roller 66, both of the rollers 66 are in contact with the actuating rod 3 in a direction perpendicular to the surface of the actuating rod 3, and the actuating rod 3 is effectively limited , High stability. When the actuating rod 3 reciprocates with the slider 6, the length of the portion of the actuating rod 3 that protrudes downward beyond the base 61 changes accordingly. Of course, in order to make the movement of the actuating rod 3 relative to the roller 66 smoother, the roller 66 may be rotatably disposed on the swing block 65.
所述牵引机构4包括牵引绳41、设置在底座11一侧并用于卷绕所述牵引绳的卷扬机42、转向机构43。所述牵引绳41通常可采用既定规格的钢丝绳,通过所述牵引绳41实现卷扬机42与转向机构43、滑动件6之间的柔性连接,避免外部冲击力直接作用在卷扬机42上,进一步提高该跟踪系统100的安全可靠性。所述转向机构43包括沿第二方向设置在所述滑轨机构5两端的一对换向轮431,所述牵引绳41的两端可分别经由两个所述换向轮431再与所述滑动件6的两个固定部64相连接。除此,所述牵引机构4的卷扬机42的安装位置不受限制,可安装在跟踪系统100中较低的位置,大大降低现场安装难度。在此,所述卷扬机42可设置在所述转动梁2所对应的位置,使得两个所述换向轮431与卷扬机42之间的部分牵引绳41长度与受力状态趋于一致。所述跟踪系统100遭遇强风或外部冲击时,所述牵引绳41可缓冲外部冲击力的影响。所述跟踪系统100实现了柔性驱动,改变了传统技术中刚性连接结构所导致的强度不足,易在外部冲击力作用下受损,使用寿命降低等问题。The traction mechanism 4 includes a traction rope 41, a winch 42 provided on the side of the base 11 and used for winding the traction rope, and a steering mechanism 43. The traction rope 41 can generally be a steel wire rope of a predetermined specification, and the flexible connection between the hoist 42 and the steering mechanism 43 and the sliding member 6 is achieved through the traction rope 41 to prevent the external impact force from directly acting on the hoist 42 to further improve the The safety and reliability of the tracking system 100. The steering mechanism 43 includes a pair of reversing wheels 431 disposed at both ends of the slide rail mechanism 5 in the second direction. Both ends of the traction rope 41 can be connected to the The two fixing portions 64 of the slider 6 are connected. In addition, the installation position of the hoist 42 of the traction mechanism 4 is not limited, and can be installed at a lower position in the tracking system 100, which greatly reduces the difficulty of on-site installation. Here, the hoisting machine 42 may be disposed at a position corresponding to the rotating beam 2, so that the length of the partial traction rope 41 between the two diverting wheels 431 and the hoisting machine 42 tends to be consistent with the force state. When the tracking system 100 encounters strong wind or external impact, the traction rope 41 can buffer the impact of external impact. The tracking system 100 realizes flexible driving, which changes the strength shortage caused by the rigid connection structure in the conventional technology, and is easy to be damaged under the impact of external impact, and the service life is reduced.
显然地,所述跟踪系统100应用于农/渔光互补等安装高度较高、难度较大的电站项目时,需适当增加所述作动杆3的长度,同时将所述卷扬机42安装在高度较低的位置,降低安装成本,且便于日后的更换和维护。Obviously, when the tracking system 100 is applied to power plant projects with high installation height and difficulty, such as agricultural/fishing-light complementary, the length of the actuating rod 3 needs to be appropriately increased, and the winch 42 is installed at the same height The lower location reduces installation costs and facilitates future replacement and maintenance.
