DETAILED DESCRIPTION

[0033] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0034] The present application will be further described below with reference to the embodiments.

[0035] Embodiment: Reference Figures 1-11 A photovoltaic tracking device for large power stations, comprising a base 1, an adjusting frame 2 installed above the base 1, a fixing frame 3 installed on the adjusting frame 2, and a photovoltaic mounting frame 38 installed on the fixing frame 3, further comprising a tracking assembly for adjusting the angle between the photovoltaic mounting frame 38 and the adjusting frame 2, comprising a fixing ring 4 fixedly installed at the top end of the adjusting frame 2, rotating frames 5 inserted into both sides of the fixing ring 4, an electric push rod 8 movably installed on one side of the adjusting frame 2 and used for pushing the rotating frames 5 to rotate, a linkage frame 7 fixedly connected with the fastening frame 6, one end of the electric push rod 8 rotatably installed on the outer wall of the adjusting frame 2, and the other end of the electric push rod 8 movably connected with the linkage frame 7, a detection hole formed in the fixing frame 3, a detection frame 37 arranged in the fixing frame 3, a plurality of photoresistors arranged on the detection frame 37, the detection frame 37 being in a "V" shape, the photoresistors being connected with a processor, a convex lens 36 arranged in the fixing frame 3, and a photosensitive lens 35 arranged in the detection hole.

[0036] As Figure 1 and Figure 2 shown, the two fastening frames 6 are driven to rotate by pushing the linkage frame 7 through the electric push rod 8, the two rotating frames 5 are driven to rotate by the fastening frames 6, and the fixed frame 3 is installed on the fastening frames 6 and the rotating frames 5, so that the fixed frame 3 is driven to rotate by the rotating frames 5 and the fastening frames 6, thereby changing the angle of the upper photovoltaic mounting frame 38 and the photovoltaic panel. The optimal photovoltaic power generation angle is achieved.

[0037] In order to improve the quality of photovoltaic tracking, in rainy days, the light source is weak, and the photosensitive lens 35 tends to be colorless, that is, the light transmittance is strong. Under the condensing effect of the lower convex lens 36, the weak light is focused on the detection frame 37, as shown in Figure 11 , the detection frame 37 is V-shaped. When the focus is located at the center of the detection frame 37, the position of the photovoltaic panel does not need to be adjusted. When the focus is not located at the center of the detection frame 37, the processor is processed, and then the electric push rod 8 is driven to adjust the rotation of the photovoltaic panel. The rotation direction is from the center point to the focus point.

[0038] In sunny weather, the light source is strong, and the photosensitive lens 35 is dark, and the light transmittance is poor. At this time, the detection frame 37 does not detect, and the light sensing element of the tracker is used to detect the position (the prior art is not described in detail).

[0039] Referring to Figures 1-11 , an automatic lubricating assembly is used to lubricate the connection between the rotating frame 5 and the fixed ring 4.

When the fastening frame 6 rotates, the conveying element conveys the lubricating oil in the oil tank 19 to the shunt block 20. The conveying element comprises two first piston pipes 10 fixedly installed on the adjusting frame 2, first piston rods 11 movably inserted into one end of the two first piston pipes 10, transmission plates 12 fixedly arranged on one end of the two first piston rods 11, a connecting plate 9 fixedly installed on the bottom wall of the fastening frame 6, and the connecting plate 9 is located between the two transmission plates 12.

The above is not described in detail as prior art. In the process of rotating the rotating frame 5, the connecting plate 9 will drive the transmission plate 12 to slide, as shown in Figure 6 When the transmission plate 12 slides, the first piston rod 11 will slide, and when the first piston rod 11 slides into the first piston tube 10, the lubricating oil in the first piston tube 10 will enter the oil distribution block 20 through the oil outlet pipe 17, flow through the sliding connection between the rotating frame 5 and the fixed ring 4 through the oil distribution hole and the guide groove, so that the rotation is smoother, and the quality of photovoltaic tracking is improved. When the first piston rod 11 slides out of the first piston tube 10, the first piston tube 10 will draw lubricating oil in the oil tank 19 through the oil return pipe 18, and the lubricating oil will flow back to the oil tank 19 under the action of gravity.
