Main beam and bearing assembly of photovoltaic tracking support and photovoltaic tracking support

Abstract

The invention belongs to the photovoltaic field, and discloses a main beam and bearing assembly of a photovoltaic tracking support and the photovoltaic tracking support. The main beam and bearing assembly comprises a bearing seat, a main beam, an upper bearing and a blocking piece, the bearing seat is used for being installed on a stand column of the photovoltaic tracking support, and a through hole is formed in the bearing seat. The main beam is inserted into the through hole, the upper bearing is inserted into the through hole and is located in a gap between the main beam and the bearing seat, and a blocking shoulder protruding out of the upper surface of the upper bearing is arranged at one end of the upper bearing. The blocking shoulder abuts against one end of the bearing seat, and agroove is formed in the other end of the upper bearing; the blocking piece is connected with the groove in a clamped manner, and the part, extending out of the groove, of the blocking piece abuts against the other end of the bearing seat. The two ends of the upper bearing are limited through the blocking shoulder and the blocking piece respectively, no relative displacement space exists between the upper bearing and the bearing seat, even if the main beam and the stand column generate the relative displacement, the upper bearing and the bearing seat cannot generate the relative displacement, so that the potential safety hazards are reduced.

Description

technical field [0001] The invention belongs to the technical field of photovoltaics, in particular to a main beam and bearing assembly of a photovoltaic tracking support and a photovoltaic tracking support. Background technique [0002] Photovoltaic tracking bracket is an important part of photovoltaic equipment. It is mainly used to assist photovoltaic modules to capture incident solar energy to the maximum extent, thereby increasing the amount of solar radiation received by photovoltaic modules and improving the overall power generation. [0003] The photovoltaic tracking support generally includes a main beam, a column and a rotary driver. The main beam is fixed on the column through a bearing seat, and the rotary driver is used to drive the rotation of the main beam, which in turn drives the rotation of the photovoltaic module installed on the main beam. At present, the solar photovoltaic tracker is required for on-site installation. The bearing is inserted into the bea...

AI Technical Summary

Problems solved by technology

In the actual construction process, due to the axial component force generated by the installation deflection angle of the column and the axial displacement caused by thermal expansion and contraction, the column and the main beam move relative to each other. After the main beam moves, the edge retaining on the main beam is caused. The hoop and the bearing seat form a relative displacement, resulting in a gap and a safety hazard
