Sunlight reflecting spotlight sun-fixing positioning sensor and tracking drive device

Abstract

The invention relates to a sunlight reflecting spotlight sun-fixing positioning sensor and a tracking drive device, and belongs to the technical field of application of solar energy. The invention consists of the sunlight reflecting spotlight sun-fixing positioning sensor and a sunlight reflecting spotlight tracking drive mechanism connected with the sunlight reflecting spotlight sun-fixing positioning sensor by a rotary main shaft (17); the sunlight reflecting spotlight sun-fixing sensor consists of a sun-fixing aiming sensor (18), and a normal incidence and reflection converter (12); and the sunlight reflecting spotlight tracking drive mechanism consists of a semi-circle driving wheel (16), a sunlight reflecting mirror (13) arranged on a support of the semi-circle driving wheel (16), a rubber driving wheel (14) arranged below the semi-circle driving wheel (16) and a DC geared motor (15) connected with the rubber driving wheel (14). The Sunlight reflecting spotlight sun-fixing positioning sensor and the tracking drive device have the advantages of simple structure, low cost, no limitation to positions, directions and angles, precise tracking and extremely high power consumption, and can be applied to medium-and high-temperature solar energy heat-concentration.

Description

Technical field: [0001] The invention relates to a sunlight reflection and concentrating heliostat positioning sensor and a tracking transmission device, belonging to the technical field of solar energy applications. Background technique: [0002] With the increasing depletion and rising prices of global chemical energy such as petroleum and coal, as well as the rising trend of low-carbon environmental protection and energy saving, solar energy applications have attracted much attention, especially high-temperature solar energy applications. However, the acquisition of high-temperature solar energy has restricted its application due to its complicated control technology, complicated manufacturing process, and high cost, and it is even elusive. The current control method is: input the earth's rotation speed and the speed of the earth's revolution around the sun and the included angle between the earth's rotation plane and the earth's revolution around the sun into the compute...

AI Technical Summary

Problems solved by technology

If there are multiple devices, especially high-temperature solar energy, which are composed of many reflective surfaces, and their positions and initial angles are different, the calibration will be more complicated

Moreover, because the active tracking method is used, it is impossible to consider the weather conditions and cloud movement conditions, resulting in controlling the concentrating surface to always point to the sun regardless of whether the weather is sunny or rainy and whether there is cloud cover or not, resulting in unnecessary power consumption

In addition, due to the use of stepping motors for control, there are disadvantages of large power consumption and high prices
