Abstract

The invention provides a fixed adjustable solar bracket employing multiple groups of parallel pulley blocks. The fixed adjustable solar bracket comprises multiple single-group brackets, wherein solar assembly brackets of the multiple single-group brackets are taken as a whole; each single-group bracket comprises one solar assembly bracket; the solar assembly bracket is aligned through positioning holes in an upper positioning bracket and positioning holes in a lower positioning bracket and then can be inserted into a positioning pin to be fixed; each solar assembly bracket drives a control pulley block through a rotating wheel; and each control pulley block drives branch ropes to adjust the angle. The multiple single-group brackets are connected in parallel, so that the bracket can be suitable for a large photovoltaic power station. Through resistance-reducing pulley blocks, the resistance of the integral solar assembly brackets in the angle adjusting process can be reduced.

Description

technical field [0001] The invention belongs to the fields of solar photovoltaic power generation and solar thermal utilization, and relates to a fixed and adjustable solar bracket and a tracking device, in particular to a fixed and adjustable solar bracket with multiple sets of parallel pulley blocks. Background technique [0002] In order to overcome the reduction of power generation caused by fixed brackets due to seasonal changes, the fixed and adjustable type has been developed rapidly. But so far, either the sliding rod type or the screw rod type are used, but there are limitations such as large adjustment torque and the screw rod is easily affected by sand and dust. [0003] For large-scale photovoltaic power plants, dozens of strings of photovoltaic modules are usually installed on a row of fixed brackets when the terrain is flat. When multiple sets are connected in parallel, a single set of solar brackets cannot meet the demand. Contents of the invention [0004...
