Novel sun-chasing transmission tracing system and photovoltaic system comprising same

Abstract

The invention discloses a novel sun-chasing transmission tracing system and a photovoltaic system comprising the same. The novel sun-chasing transmission tracing system comprises a multi-square arc tube, a vertical post and a shift wheel transmission mechanism, wherein the multi-square arc tube is used for supporting a photovoltaic panel, the vertical post is used for the multi-square arc tub, theshift wheel transmission mechanism comprises a driving motor, fan-shaped shift teeth and a roller, annular teeth are arranged on a peripheral wall of the fan-shaped shift teeth and are engaged with the roller, the driving motor drives the roller to rotate so as to drive the fan-shaped shift teeth to rotate so that the multi-square arc tub is driven to do sun-chasing motion by the fan-shaped shiftteeth; limitation teeth are arranged at initial ends and tail ends of the fan-shaped shift teeth along extension directions of the annular teeth and protrude outwards in a radial direction, and the sizes of the limitation teeth along a radiation direction of the fan-shaped shift teeth are larger than the sizes of teeth of the annular teeth along the radial direction of the fan-shaped shift teeth.The novel sun-chasing transmission tracing system is high in mechanical strength, favorable in limitation performance and simple in structure, is easy to implement and is reliable; and since the limitation teeth are arranged at two ends, the limitation position is clear and is convenient to maintain, and the maintenance difficulty is reduced.

Description

technical field [0001] The invention relates to the field of photovoltaic technology, in particular to a novel sun-tracking transmission tracking system and a photovoltaic system comprising the same. Background technique [0002] Existing photovoltaic tracking systems are mainly single-system large-capacity photovoltaic tracking systems because they are widely used in ground power stations. Due to the required capacity, a single set of photovoltaic tracking system usually needs to install more photovoltaic modules, resulting in a longer main beam of the photovoltaic tracking system. However, long girders are easily deformed by wind loads in strong wind environments. To increase the load resistance capacity, the thickness of the girder is usually increased, which not only greatly increases the cost, but also puts forward higher requirements for structural design. [0003] Photovoltaic tracking systems have a certain tracking range. How to make the photovoltaic tracker stop a...

Due to the required capacity, a single set of photovoltaic tracking system usually needs to install more photovoltaic modules, resulting in a longer main beam for the photovoltaic tracking system

However, the long main girder is easily deformed by wind load in a strong wind environment. To increase the load resistance capacity, the thickness of the main girder is usually increased, which not only greatly increases the cost, but also puts forward higher requirements for structural design.
