Three-axis sunlight tracking and attitude-adjustment exposure frame

Abstract

The invention discloses a three-axis sunlight tracking and attitude-adjustment exposure frame. The three-axis sunlight tracking and attitude-adjustment exposure frame comprises a support, a frame body and a control unit; the support comprises a base, a first supporting pillar, a first motor, a second supporting pillar, a second motor, a third supporting pillar and a third motor; two side surfaces at the external side of the frame body which are perpendicular to each other are provided with a first light sensor and a second light sensor; and the surface of the frame body is provided with a third light sensor. According to the three-axis sunlight tracking and attitude-adjustment exposure frame of the invention, a three-axis mobile mechanism is adopted to carry out attitude adjustment, so that the degree of freedom and the spatial mobility of the overall unit can be greatly improved; the second supporting pillar and the third supporting pillar are constantly perpendicular to each other spatially, and therefore, displacement control can be more convenient, and planar dead-angle-free mobile operation can be ensured; the light sensors are perpendicular to each other in pairs, so that light signals can be obtained completely, and the excellent tracking effect of the device can be ensured; and since the light sensors are set in such a way, a requirement for real-time tracking can be satisfied, and automation degree is high.

Description

technical field [0001] The invention relates to a three-axis sunlight tracking capital adjustment exposure frame. Background technique [0002] In the application field of solar energy, in order to make better use of the sun's rays, the exposure racks in the solar equipment are equipped with tracking and adjustment mechanisms to adjust the posture according to the angle of the sun's rays, so that the normal direction of the plane where the exposure rack is located is in line with the The incident light remains parallel. The number of drive shafts used in the current tracking fund exposure rack is generally single-axis or double-axis. This structure restricts the degree of freedom and spatial mobility of the whole machine, making the ray tracing width smaller and affecting the scope of application of the product. In addition, the attitude adjustment accuracy of the structural target currently used is insufficient, the sensor arrangement is simple, and more directions and pla...

AI Technical Summary

Problems solved by technology

The number of drive shafts used in the current tracking fund exposure frame is generally single-axis or double-axis. This structure restricts the degree of freedom and spatial movement capability of the whole machine, making the ray tracing width smaller and affecting the scope of application of the product.

In addition, the attitude adjustment accuracy of the structural target currently used is insufficient, the sensor arrangement is simple, and more directions and planes cannot be obtained, especially the light information on the back, which makes the tracking equipment invalid. It cannot meet the real-time tracking requirements under dynamic use conditions. The direction of light collection needs to be adjusted in advance, and the degree of automation is not high, which may also lead to missed opportunities to capture light, resulting in waste of energy and a decrease in the accuracy of the whole machine
