Description

Technical Field

[0001] The present invention belongs to the field of solar thermal collectors, and more particularly to a light-tracking solar thermal collector. Background Art

[0002] In a photovoltaic support device, angle adjustment is achieved by adjusting the height and inclination of the support. In actual operation, the angle adjustment usually needs to be adjusted according to factors such as local latitude and longitude, meteorological conditions, and the type of photovoltaic module. Angle adjustment of photovoltaic support devices usually uses two methods: manual or automatic. Manual angle adjustment requires manual climbing of the pole for adjustment, so it is suitable for small-scale power stations. Automatic angle adjustment, on the other hand, can achieve full-automatic operation and is widely used in large-scale power stations.

[0003] To improve the power generation efficiency of solar panels, an automatic tracking system can be adopted. The automatic tracking system can adjust the orientation of the solar panel in real time according to the position of the sun, ensuring that the solar panel is always facing the sun's rays. This system can greatly improve the power generation efficiency of solar panels. Automatic angle adjustment usually uses devices such as angle adjustment piles, sensors, and control systems. First, information such as the solar altitude angle and azimuth angle is obtained through sensors, then the height of the support is calculated through the control system to achieve automatic adjustment, and finally the support is automatically rotated to a suitable position by an actuator, so that the solar heat collection panel faces the sun. Through angle adjustment, higher power output can be achieved by photovoltaic modules on the same piece of land, thus saving land costs.

[0004] Generally, the height of the front support of a solar photovoltaic power station is 1 - 2 meters, the height of the rear support is 2 - 4 meters, and the inclination angle of the support is 10 - 30 degrees. To prevent the solar heat collection panel from being blocked by buildings, photovoltaic devices are usually installed in locations with high altitude and open surroundings to prevent occlusion and ensure sufficient solar radiation can be received. For photovoltaic devices installed in open or high locations, since they need to have an automatic light-tracking function, the solar heat collection panel and the bottom support are usually in a movable structure to facilitate rotation of the solar heat collection panel and cooperate with the sun's light direction for light-tracking work. Since there is no occlusion, relatively speaking, the surrounding wind directly acts on the surface of the solar heat collection panel. The rotatable solar heat collection panel needs to be connected to the motor shaft of the rotating device to achieve rotation, so in windy weather, due to non-fixed installation, the solar heat collection panel is prone to shaking. In the case of long-term shaking, the structures such as screws on the surface of the photovoltaic device will become loose, affecting the stability of the entire device.

[0005] In summary, the present invention provides a light-tracking solar thermal collector to solve the above problems. Summary of the Invention
