Problems solved by technology

However, the consumables of the steering mechanism on each solar photovoltaic are too large to cause waste, so a linkage photovoltaic tracking system was developed. Each photovoltaic tracking system is connected through a linkage structure, and the angles of multiple solar photovoltaic panels are adjusted through the linkage structure, but now Some linkage structures have low strength and poor stability. In windy and snowy weather, the linkage structure will be damaged due to excessive force, and the linkage mechanism has poor support effect on photovoltaic panels.

Embodiment 1

[0052] like Figures 1 to 3 As shown, this specific embodiment discloses a photovoltaic tracking system, including: a plurality of pillars 100; a plurality of main beams 200, and a plurality of main beams 200 are arranged side by side; There are bearings on the top, the shaft head of the main beam is located on the bearing of the pillar, the main beam can rotate on the pillar, the main beam 200 is used to install the solar photovoltaic panel A; at least one connecting rod assembly 400, the connecting rod assembly 400 is connected to the same The main beam 200 and the connecting rod assembly 400 include a pair of swing arms 410 and a connecting rod 420. One end of the swing arm 410 is fixedly connected to the main beam 200, and the other end is hinged to the connecting rod 420, and the connecting rod 420 is located on the pair of swing arms 410. Between them, the swing arm 410 includes two sub-swing arms 411, and there is a certain angle between the two sub-swing arms 411, and ...

Embodiment 2

[0062] The structure of the photovoltaic tracking system disclosed in the second embodiment is basically the same as that of the first embodiment, the difference is that in this embodiment, such as Figure 10 As shown, the transmission mechanism 500 is an electric push rod. The input end of the electric push rod is arranged on the pillar 100 and connected to the driving device, and the output end of the electric push rod is hinged to the third long beam of the first main beam 300 . The driving device controls the expansion and contraction of the electric push rod, the electric push rod drives the first main beam to rotate, and the first main beam drives the adjacent main beam to rotate through the connecting rod assembly.

Embodiment 3

[0064] The structure of the photovoltaic tracking system disclosed in the third embodiment is basically the same as that in the first embodiment, the difference is that in this embodiment, such as Figure 11 As shown, the transmission mechanism 500 includes a rotating shaft and an arc-shaped gear 532, wherein the rotating shaft 531 is provided with a toothed protrusion, the rotating shaft 531 meshes with the arc-shaped gear 532, and the rotating shaft is connected with the output end of the driving device. The toothed arc section of the arc gear 532 meshes with the rotating shaft, and the straight end of the arc gear 532 is fixedly connected with the first main beam 300. The contact area between the arc gear and the first main beam is large, and the fixed form is firm. The driving device drives the rotating shaft 531 to rotate, and the rotating shaft 531 meshes with the transmission arc gear 532. The arc gear 532 drives the first main beam to rotate, and the first main beam dri...

Description

technical field [0001] The invention relates to the design field of solar photovoltaic tracking systems, in particular to a photovoltaic tracking system. Background technique [0002] Traditional fuel energy is decreasing day by day, and the damage to the environment is becoming more and more prominent. At the same time, there are still 2 billion people in the world who do not have normal energy supply. At this time, the whole world is turning its attention to renewable energy, hoping that renewable energy can change the energy structure of mankind and maintain long-term sustainable development. Among many renewable energy sources, solar energy has become the focus of people's attention due to its unique advantages. Abundant solar radiation energy is an important energy source, which is inexhaustible, non-polluting, cheap, and can be freely utilized by human beings. [0003] In the prior art, in order to increase the conversion rate of solar energy, a photovoltaic tracking...
