Problems solved by technology

However, for large-scale or super-large solar energy collection and utilization devices, since the weight of the huge concentrating module array is borne by a column, the supporting frame is easily deformed and the driving is difficult; and because the rotation radius is too large, even if the azimuth angle Or a small error at the center axis of the elevation angle will be greatly magnified at a position far away from the center, so it is difficult to achieve accurate tracking of all concentrating modules; a large array of concentrating modules is like an open sail. The strong torque generated by the strong wind may even damage the mechanical transmission mechanism
The U.S. patent "Two-axis tracking solar collector mechanism" with the patent number US5169456 proposes a large-scale automatic tracking solar collector mechanism, which includes a two-axis tracking mechanism, a lightweight support frame and an array of concentrating modules composed of Fresnel lenses , in which the two-axis tracking mechanism is driven by two sets of active worm gear and worm gear mechanisms to adjust the azimuth and elevation angles of the light-concentrating module array. The device has good windproof performance, is not easy to deform, and has high tracking accuracy, but The two-axis tracking mechanism is too complicated, the processing cost is expensive, and the installation accuracy is high, so it is difficult to popularize and apply

Embodiment 1

[0017] The structure of a large-scale wind-proof automatic tracking solar daylighting device according to the first embodiment of the present invention is shown in Fig. 1, and includes a light-concentrating module 02 array composed of light-concentrating elements 01 and its supporting frame 03, and an array of driving light-concentrating modules 02 tracking the sun. The azimuth angle drive mechanism and the altitude angle drive mechanism, the tracking control circuit (not shown in the figure) that controls the azimuth angle and the altitude angle drive mechanism, the sunlight azimuth angle sensor 05 and the altitude angle sensor 06 that transmit signals to the tracking control circuit. The concentrating module array includes five columns of concentrating modules 02, and each column of concentrating module 02 is composed of eight concentrating elements 01 arranged in a row, which respectively pass through five parallel north-south axis AA', BB', CC' , DD', EE' are hinged on the sup...

Embodiment 2

[0023]The basic structure of this embodiment is the same as the first embodiment. The difference is: 1. The light-concentrating module array is driven by a set of sprocket synchronous transmission mechanism, and each row of light-concentrating modules rotates around its own rotating shaft; 2. The height angle drive mechanism is a hydraulic drive mechanism.

[0024] The specific structure is shown in Figure 3. The azimuth drive mechanism is mainly composed of a motor 20 controlled by a tracking control circuit and a sprocket synchronous transmission mechanism. The sprocket synchronous transmission mechanism is mainly composed of a driving sprocket 21, a chain 22 and four sprockets. 23 composition. The motor 20 is fixedly connected to the support frame 03, and its output shaft is connected to the driving sprocket 21 through the reducer 24. The driving sprocket 21 is installed on the shaft of a row of concentrating modules, and is installed on the shaft of the concentrating module 02...

Embodiment 3

[0028] The structure of this embodiment is basically the same as that of the second embodiment. The difference is that the height angle drive mechanism is composed of a set of sprocket synchronous transmission mechanism and two sets of screw nut mechanism. Two sets of the same screw-nut mechanism are hinged on both sides of the support frame, so that not only the height angle adjustment function is still realized, but also the weight of the condenser module array can be shared with multiple fixed columns, so it can further prevent light concentration The support frame of the module array is deformed, and the influence of wind is eliminated more effectively; the sprocket synchronous transmission mechanism can make the two sets of screw and nut mechanisms synchronously adjust the height angles on both sides of the support frame, making the present invention suitable for larger windproof automatic Tracking sun lighting device.

[0029] The specific structure is shown in Figure 5, the...
