Problems solved by technology
[0004] At present, foreign research and development institutions or companies use single-axis linkage mechanism (motor-driven moving rod) or single-axis motor deceleration drive. These methods of tracking the sun in the mirror field have the problems of low tracking accuracy and high cost. At the same time, due to reflection The mirror surface cannot be turned over at the same time, which is inconvenient to clean the mirror surface, which not only greatly reduces the efficiency of light concentrating and heat collection, but also is not conducive to commercialization

The invention discloses a tracking transmission control device for a reflective linear Fresnel solar concentrator, comprising a set of driving devices, a set of primary speed reduction devices, multiple sets of secondary speed reduction devices, multiple sets of angle adjustment devices; a drive device Including the drive motor and its control system, the control system presets the sun tracking program, the drive motor works, and automatically tracks the sun; the primary reduction device includes the primary reducer, flange, coupling, and bearing support; the secondary reduction device includes the secondary Reducer, coupling, transmission shaft, fixed seat, the output end of each secondary reducer is connected with the mirror shaft; the angle adjustment device includes an electromagnetic clutch, which drives the electromagnetic clutch to work through a preset program to determine each group of mirrors the initial angle, and the linkage to track the sun synchronously, as well as ensure that each mirror returns to the horizontal and vertical position in high wind or hail weather conditions. The invention has the advantages of accurate tracking accuracy, convenient control, low cost and convenient mirror surface cleaning.
Description
technical field [0001] The invention belongs to the technical field of solar energy utilization, and discloses a tracking transmission control device for a reflective linear Fresnel solar collector. Background technique [0002] Reflective linear Fresnel solar concentrator power generation is a new medium-high temperature solar thermal power generation method newly studied in recent years, and reflective linear Fresnel solar concentrator is the core of this power generation method. Such as figure 1 As shown, a transmission control device 101 is installed correspondingly under each reflector 100, and the transmission control device 101 is installed on a support 102. A plurality of reflective mirrors 100 form a reflector field 103, and a light collector 104 is installed on the reflector field 103. The concentrator 104 is arranged parallel to the reflector field 103, and the working principle of the reflective linear Fresnel concentrator is that the rectangular reflector field...
