Autotracking link gear of solar concentrating photovoltaic power generation array

Abstract

The invention discloses an automatic tracking linkage mechanism of a solar energy concentration photovoltaic power generating array, which comprises a solar concentrator array, an altitude linkage mechanism, and an azimuth linkage mechanism. The solar energy concentration photovoltaic power generating array drives the whole array of all concentrators to obliquely track a solar altitude through a set of altitude driving mechanism, and drives the whole array of all concentrators rotate around a transmission shaft to track a solar azimuth through a set of azimuth driving mechanism. The whole solar energy concentration photovoltaic power generating array only adopts the set of the altitude driving mechanism and the set of the azimuth driving mechanism, so that the whole array of all concentrators realize tracking the running of the sun by two-dimensional linkage, and the tracking cost is low; moreover, the altitude driving mechanism and the azimuth driving mechanism are formed by simple mechanisms completely, so that the whole solar energy concentration photovoltaic power generating array is manufactured easily, and has high tracking accuracy and strong capability of strong wind resistance.

Description

technical field [0001] The invention relates to the technical field of solar energy utilization, in particular to an automatic tracking linkage mechanism of a solar concentrated photovoltaic power generation array. Background technique [0002] Solar energy is a clean and pollution-free renewable energy, inexhaustible and inexhaustible. Fully exploiting solar energy can not only save the increasingly depleted conventional energy, alleviate the severe shortage of resources, but also reduce pollution and protect human beings. ecological environment for survival. Among many solar energy utilization technologies, solar photovoltaic power generation technology realizes the direct conversion of solar energy into electric energy, which is the most convenient way of utilization. It has the characteristics of safe and reliable operation, no fuel, no noise, no pollution, local utilization, It is easy to use and maintain, and the scale can be large or small, so it has been valued by c...

Problems solved by technology

Although my country has very good solar energy resources and photovoltaic cell manufacturing capacity, the overall level of the solar photovoltaic industry is still far behind that of developed countries. First, the production of crystalline silicon raw materials used in solar cells depends on imports, and raw materials are in short supply. Even for a long period of time in the future, there is little room for cost reduction. Second, there are still few applications of solar photovoltaic systems.

[0006] In recent years, concentrating photovoltaic power generation technologies at home and abroad generally use single column and orbital two-dimensional tracking of the sun to run. Because of the single-machine two-dimensional tracking, the tracking cost is high

In order to reduce the cost of tracking, a set of tracking mechanism is mainly used to drive a large concentrator to run, but as the size of the model increases, its cost also doubles and its stability is poor. The basic requirements of the place of use are also very high, which greatly limits the promotion of concentrated photovoltaic power generation technology
