Supporting structure for solar flat single shaft tracking system

Abstract

The invention discloses a supporting structure for a solar flat single shaft tracking system. The solar flat single shaft tracking system comprises a solar cell module and horizontal rotating shafts, wherein the horizontal rotating shafts and the solar cell module are fixedly connected as an integrated structure. The supporting structure comprises a support frame, a roller assembly and a connection shaft on the support frame, wherein the connection shaft connects the adjacent two horizontal rotating shafts; the shaft center of the connection shaft and the shaft center of the horizontal rotating shafts are not on the same straight line; after the connection shaft and the horizontal rotating shafts are connected, the connection shaft and the horizontal rotating shafts are displayed as a crankshaft structure integrally; and the connection shaft is arranged on the corresponding roller assembly. The supporting structure for a solar flat single shaft tracking system of the invention forms a crankshaft structure through coordination of the connection shaft and the horizontal rotating shafts integrally, thus being able to conveniently adjust the centre of gravity position according to the characteristics of the assembly, and at the same time the connection shaft rotates through the roller assembly on the support frame to convert the sliding friction of an existing structure into rolling friction, thus effectively reducing the driving moment.

Description

technical field [0001] The invention belongs to the technical field of solar tracking, in particular to a support structure for a solar flat single-axis tracking system. Background technique [0002] The structure of the existing solar flat single-axis tracking system is to install solar cell components on the horizontal shaft, the horizontal shaft is connected to the support ring through a large plastic bearing, the support ring is connected to the ground through a column, and a swing connecting rod is installed on the horizontal shaft. The rod drives the horizontal shaft to rotate ±45 degrees. [0003] In the above structure, it is difficult for the rotation center of the horizontal shaft to coincide with its center of gravity. In actual installation, it is necessary to adjust the center of gravity by adjusting the distance between the swing link and the horizontal shaft or by adding a counterweight. Moreover, the plastic bearing has a large external dimension, which is di...

Problems solved by technology

[0003] In the above structure, it is difficult for the rotation center of the horizontal shaft to coincide with its center of gravity. In actual installation, it is necessary to adjust the center of gravity by adjusting the distance between the swing link and the horizontal shaft or by adding a counterweight. Moreover, the plastic bearing has a large external dimension, which is different from that of the horizontal shaft. The support ring is not easy to achieve a good fit, and at the same time, the contact area with the support ring is large, the relative friction is relatively large, and a large driving torque is required
