Description

Swing arm device of photovoltaic tracking support

Technical Field

The utility model relates to a solar photovoltaic tracking support system, in particular to a swing arm device of a photovoltaic tracking support.

Background

When the solar photovoltaic bracket tracking system is installed on the ground or on the water surface, the movement of the sun needs to be tracked in real time, and the direction (such as the movement from east to west) of a photovoltaic module is adjusted, so that sunlight directly irradiates to a light receiving plane of a photovoltaic panel, and the photovoltaic power generation amount is improved. A conventional photovoltaic rack tracking system, such as that shown in fig. 1 and 2, has a photovoltaic main shaft 1 mounted on a column 2, for example, by bearings (not shown). One end of one swing arm cantilever 3 is sleeved on the main shaft 1 through the hoop 4, and the other end of the swing arm cantilever is connected with a telescopic rod of the electric push rod 6, for example, when the electric push rod 6 runs under the control of the tracking device, the telescopic rod drives the swing arm cantilever 3 to swing around the main shaft 1, and further drives the main shaft 1 to rotate, so that the photovoltaic module installed on the main shaft 1 can track the movement of the sun. However, in the swing arm anchor ear 4 shown in fig. 1, the part connected with one end of the swing arm cantilever 3 is connected by welding, and since the other end of the swing arm cantilever 3 is connected with the push rod 6 mounted on the upright post 2, an inverted triangle relationship is formed between the three parts, so that the swing arm cantilever 3 and the anchor ear 4 are not connected in a vertical right-angle shape, and thus, when the two are welded, the problem of large processing error caused by difficult positioning exists. In addition, the swing arm cantilever 3 and the push rod 6 shown in fig. 1 are directly connected, and a flexible adjusting mechanism is lacked, so that a larger position needs to be reserved at the installation position of the swing arm cantilever 3 and the push rod 6, so that the interference and clamping of the swing arm and the push rod are avoided, and the strength of the swing arm is influenced.
