A rotating mechanism for driving the mounting bracket to rotate up and down is provided on the rotating part of the rotary reducer. Photosensitive sensors and control boxes are respectively provided on the front and back sides of the mounting bracket. The rotating mechanism, the rotary reducer, and the photosensitive sensors are all controlled by the control box.

[0006] In a preferred embodiment, the rotating mechanism includes a motor, a planetary reducer, a lower connecting frame, and an upper connecting frame. The lower connecting frame is in a "U" shape structure. A rotating shaft is horizontally arranged between the lower connecting frames.

In this utility model, a rotary reducer is used as the horizontal rotation power source of the solar thermal power generation equipment, and a motor + planetary reducer is used as the vertical rotation power source of the solar thermal power generation equipment.

[0018] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] Reference Figure 1-2, a solar thermal power generation tracking device, including a vertical pole 2 and a mounting bracket 3 for installing a reflecting lens. At the top of the vertical pole 2, there is a rotary reducer 6 for driving the mounting bracket 3 to rotate horizontally. On the rotating part of the rotary reducer 6, there is a rotating mechanism for driving the mounting bracket 3 to rotate up and down. On the front and back sides of the mounting bracket 3, there are respectively a photosensitive sensor 4 and a control box 11. The rotating mechanism, the rotary reducer 6 and the photosensitive sensor 4 are all controlled by the control box 11. The rotating mechanism includes a motor 8, a planetary reducer 9, a lower connecting frame 7 and an upper connecting frame 5. The lower connecting frame 7 is of a "U" - shaped structure. A rotating shaft 10 is horizontally arranged between the lower connecting frames 7. The upper and lower ends of the upper connecting frame 5 are respectively fixedly connected to the mounting bracket 3 and the rotating shaft 10. The motor 8 and the planetary reducer 9 are both installed on one side of the lower connecting frame 7. The output end of the motor 8 is connected to the input end of the planetary reducer 9. The output end of the planetary reducer 9 is fixedly connected to the rotating shaft 10. The rotary reducer 6 is used as the horizontal rotation power source of the solar thermal power generation device. The rotary reducer 6 can achieve unlimited circumferential rotation and deceleration, and can withstand large axial forces, radial forces and overturning forces. At the same time, the motor 8 + planetary reducer 9 is used as the up - and - down rotation power source of the solar thermal power generation device. While ensuring the overall structure is compact, it increases the overall output torque (moment) and power, and can also significantly improve the overall stability and the ability to resist impact and vibration, and can ensure the accuracy during the overall adjustment.

[0020] Further, the overall upper connecting frame 5 is of an "I" - shaped connection structure. The above design can ensure the strength and stability of the upper connecting frame 5 to support the mounting bracket 3.

[0021] Further, the bottom of the vertical pole 2 is fixedly connected with a base 1. The base 1 is in the shape of a frustum of a cone with a narrow top and a wide bottom. There are also fixing bolts on the base 1 for installing at the placement position. Since the base 1 is in the shape of a frustum of a cone as a whole, it can increase the contact area with the placement surface, thereby ensuring the strength after subsequent installation and being not prone to phenomena such as tipping.

[0022] Further, an inclination sensor 12 electrically connected to the control box 11 is also provided on the top of the rotary reducer 6. Designing an inclination sensor 12 for monitoring the overall levelness on the top of the rotary reducer 6 can monitor the overall levelness of the solar thermal power generation device in real - time before and after installation to ensure the overall accuracy during installation. At the same time, it can also monitor in real - time whether the device as a whole is tilted due to soil settlement or other factors during subsequent use.

[0023] Further, the control box 11 is communicatively connected to an external control terminal (not shown in the figure) by wire. Through the external control terminal, the work of the tracking device can be remotely controlled, and at the same time, the data changes of the tracking device can be collected in real - time. The external control terminal is preferably a computer.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
