A solar heat collecting and tracking drive unit, comprising a driven assembly (102) connected to at least two reflector rotary shafts (8) and a driving assembly connected to the driven assembly (102) by means of a transmission assembly (101). The driving assembly drives the driven assembly (102) to perform reciprocating motion along a fixed track by means of the transmission assembly (101). Also disclosed are a solar heat collecting and tracking drive array and a heat collecting device. Multiple reflector rotary shafts (8) can perform synchronous reciprocating rotation at the same angular speed, and meanwhile, multiple sets of reflectors (9) can be in synchronized linkage and precisely track the sun. The solar heat collecting and tracking drive unit and array and the heat collecting device have high tracking precision, simple and reliable control, high transmission efficiency, easy and convenient installation, and low costs. |
