The invention relates to a solar tracking system, especially to a rotary solar single-shaft tracking system comprising a plurality of solar photovoltaic assembly units. The solar photovoltaic assembly units include standing columns; rotating shafts are fixed at the standing columns; and photovoltaic assemblies are fixed at the rotating shafts. A rotating arm is fixed at one end of each rotating shaft and all the rotating arms are connected by connecting ropes; the connecting ropes are fixed at drive units; and the drive units drive the rotating arms to make rotation by the connecting ropes. According to the invention, the system has the simple structure; multiple rotating shafts can be driven synchronously to follow the sun position synchronously; the rotary drive mechanism only bears the torque and large and independent foundation is not required; and the conversion efficiency of the sun light is improved. And technical problems that the existing solar tracking system has the complicated structure; simultaneous rotation of multiple rotating shafts can not be realized; and the conversion efficiency of the sun light is low in the prior art can be solved.

Example Embodiment

[0031] Examples:
[0032] Such as figure 1 with 2 As shown in and 3, a gyroscopic solar single-axis tracking system includes a plurality of solar photovoltaic module units 28, the solar photovoltaic module unit 28 includes a column 5, a shaft 1 is fixed on the column 5, and a plurality of photovoltaic modules are fixed on the shaft 1 Component 2. The solar photovoltaic module units 28 are arranged in a matrix form, and the rotating shafts 1 in the same matrix are parallel to each other, and two rotating shafts in different matrices but on the same straight line are connected by a rotating shaft connection structure. The two ends of the rotating shaft 1 are fixed on the upright post by split square bearings.
[0033] The rotating shaft 1 is fixed with a rotating arm 4 perpendicular to the rotating shaft. The rotating arm 4 includes an upper rotating arm 11 and a lower rotating arm 10. The upper and lower rotating arms are welded to the rotating shaft 1. The upper and lower rotating arms are perpendicular to the rotating shaft 1. Two adjacent upper rotating arms 11 are connected by steel cables 3, and two adjacent lower rotating arms 10 are also connected by steel cables 3, and the two steel cables 3 are parallel to each other. A column 5 is fixed between the mutually parallel rotating shafts, and a driving device is installed on the column 5, and the number of rotating shafts 1 on both sides of the driving device is equal. The driving device includes a rotating disk 7 fixed on a column. A rotating rod 29 is provided under the rotating disk 7, and a motor 9 is connected to the rotating rod 29. The motor 9 drives the rotating rod 29 to rotate. The rotating rod 29 and the rotating disk 7 are matched with a worm gear In this way, the rotation of the rotating rod 29 drives the rotating disk 7 to rotate. Such as Figure 4 As shown, a concentric rotating plate 8 is fixed on the rotating disk 7. The upper and lower ends of the rotating plate 8 are each fixed with a fixed shaft 30. Two shackles 12 are sleeved on the fixed shaft 30. The shackle 12 is U-shaped and has an opening. There is a cylindrical ring 14 on the two free ends of the, the cylindrical ring is sleeved on the fixed shaft, and the U-shaped space 15 formed is sleeved with the fixed ring 31 at the end of the steel cable (such as Image 6 Shown). The other end of the steel cable 3 is fixed on the rotating arm 4. The rotating arm 4 is equally fixed with a fixed shaft 30, two shackles 12 are installed on the fixed shaft 30, one shackle 12 is connected to the rotating plate 8 of the driving device through a steel cable 3 to the left, and the other shackle 12 Connect another rotating arm 4 through a steel cable 3 to the right. Such as Figure 5 As shown, one of the two ends of the steel cable 3 is equipped with a screw buckle 13. The screw buckle 13 includes a U-shaped buckle at both ends and a spiral body in the middle. The length of the steel cable can be adjusted by adjusting the spiral body, so that the steel cable The length of the buckle is adjusted to the required length, one of the U-shaped buckles is used to connect with the shackle, and the other U-shaped buckle is connected with the fixing ring of the steel cable. The steel cable 3 connects the rotating arms to form an annular rotating chain. The driving device drives the rotating arms to rotate, thereby driving the rotating shaft to rotate. The rotation of the rotating shaft causes the photovoltaic modules on it to also rotate, forming a tracking of sunlight. When the photovoltaic modules are all facing upwards, the distance between the upper and lower rows of steel cables is the largest. When the rotating plate swings left and right, the maximum swing angle is 60°. When swinging, the distance between the upper and lower rows of steel cables gradually decreases. Due to the restriction of the installation terrain, the steel cable is allowed to form an offset angle α, 0°≦α≦30°.
[0034] Such as Figure 7 As shown, the center of the bearing is a square through hole. The bearing is composed of two semicircular bearing bodies 17 with the same shape and structure. An arc-shaped working surface is provided on the arc-shaped outer surface of the bearing body 17, and there is a rib 20 on both sides of the working surface. The rib 20 is arc-shaped. The arc of the rib 20 is the same as that of the bearing body. The curvature of the outer surface is the same. A rectangular positioning groove is opened on the plane forming the inner surface of the bearing body 17, two bearing bodies are spliced ​​to form a circular bearing, and the two positioning grooves form a square through hole in the center of the bearing body for accommodating the square shaft 1 . The bearing end cover 16 is in the shape of a semi-circular arc. The two sides of the bearing end cover are the connecting body 18, the connecting body 18 is a hollow cuboid, the upper surface of the connecting body 18 is a smooth plane, and the lower surface of the connecting body 18 is a tooth surface. A bolt hole is opened in the middle of the upper surface of the connecting body 18, and the bolt hole penetrates the tooth surface of the lower surface of the connecting body. The inner arc surface of the bearing end cover is the contact surface, and the contact surface matches the working surface. The bearing base 19 includes a contact surface matingly connected with the working surface. Below the contact surface is a support seat. Connecting bodies are integrally formed on both sides of the contact surface. The structure of the connecting body is the same as that of the connecting body on the bearing end cover.

The cross section of the connecting structure 21 is rectangular, and the area of ​​the cross section is half of the rotating shaft 1. The connecting structure 21 is a hollow rectangular tube body, the connecting structure 21 is flush with the bottom surface of the rotating shaft 1, and the longitudinal section of the rotating shaft 1 is in the shape of a rectangular wave. A cover 25 is welded to the joint between the rotating shaft 1 and the connecting structure 21, and the size of the cover 25 is the same as the size of the gap between the rotating shaft 1 and the connecting structure 21. The bottom surfaces of the two connecting structures 21 are flush with the bottom surface of the rotating shaft 1, the upper surface of the connecting structure 21 is a connecting and fixing surface 23, and there are positioning pieces and fixing pieces on the connecting and fixing surface 23. The positioning member includes a reinforcing rib 26 and a slot 22. The reinforcing rib 26 is located at one end of the connecting and fixing surface 23 close to the shaft 1.
