Abstract

The present invention relates to the field of photovoltaic technologies, and provides a one-way transmission photovoltaic tracker and a photovoltaic tracker array. Said photovoltaic tracker comprises: an upright column for supporting the one-way transmission photovoltaic tracker; a one-way transmission device for breaking the transmission of opposite torque along a main beam during the rotation of the photovoltaic tracker, the lower end of the one-way transmission device being connected to the top end of the upright column; the main beam, inserted in the one-way transmission device, and rotatably connected to the upright column by means of the one-way transmission device; and a photovoltaic assembly, fixed on the main beam, and being able to rotate on the upright column along with the main beam. The described structure is able to reduce the superimposition of an opposite torque towards the center of the main beam, avoiding damage to the center of the main beam because of bearing too large opposite torque.

Abstract

Disclosed are a main beam and an application thereof, and a photovoltaic tracking support, wherein the main beam comprises a flat plate and an elliptical arc plate, two ends of the flat plate are fixedly connected to corresponding ends of the elliptical arc plate respectively to form a ring, and the plane at which the flat plate is located is perpendicular to the long axis of the ellipse at which the elliptical arc plate is located. Provided at the same time is an application of the main beam in the photovoltaic tracking support. The photovoltaic tracking support comprises a main beam, and further comprises: a column; and a bearing seat, which comprises a bearing ring, a Z-shaped support plate and a bottom plate that are successively connected, wherein a cross-sectional shape of the Z-shaped support plate is Z-shaped, the main beam is installed in the bearing ring, the flat plate of the main beam is directly opposite to a photovoltaic module, and the bottom plate is connected to the column. Under the premise of ensuring the same thickness, the main beam of the present invention improves the transverse sectional resistance moment and saves on costs. The main beam may be used in the photovoltaic tracking support to reduce the hot spot effect of a double-sided photovoltaic assembly and extend the service life of the double-sided photovoltaic assembly.
