Mechanical double-shaft solar tracking bracket

Abstract

The invention relates to a mechanical double-shaft solar tracking bracket which comprises a vertical column, a sun hour angle tracking mechanism, a spiral spring force accumulating mechanism, an escapement speed regulating mechanism, a transmission locking mechanism, an altitude angle tracking mechanism and a solar cell panel, wherein the vertical column is installed on the lower end of a sun hour angle tracking motor in the sun hour angle tracking mechanism; one end of a spiral spring shaft of the spiral spring force accumulating mechanism is connected with a gear of the sun hour angle tracking mechanism; the escapement speed regulating mechanism is connected with a spiral spring shaft output gear which is arranged at the other end of the spiral spring shaft in the spiral spring force accumulating mechanism by a transition gear; a locking claw of the transmission locking mechanism locks or releases an input gear of the escapement speed regulating mechanism; a solar cell installation panel is installed outside a sun hour angle installation panel of the altitude angle tracking mechanism; and the solar cell panel is fixedly installed on the solar cell installation panel. The mechanical double-shaft solar tracking bracket has the advantages of simple mechanical structure, stable running, low production cost, short running time of an electric control system and low start frequency and prolongs the service life of the system to a great extent.

Description

technical field [0001] The invention relates to the field of solar tracking brackets, in particular to a mechanical dual-axis solar tracking bracket. Background technique [0002] At present, there are three tracking methods widely used in solar photovoltaic automatic tracking systems, namely, horizontal single-axis tracking, inclined latitude angle oblique single-axis tracking and dual-axis tracking. Axis tracking has two rotational degrees of freedom. The tracking control strategy adopted by the three tracking systems is an active tracking control strategy, which calculates the orientation of the sun in the sky and controls the orientation of the photovoltaic array. This active photovoltaic automatic tracking system can be better applied in the environment with a lot of frost, snow and dust, and can also work reliably in an unattended photovoltaic power station. [0003] However, since the existing solar photovoltaic automatic tracking systems rely on motors to precisely...
