Rotary luffing sun tracker

Abstract

The invention discloses a rotary luffing sun tracker, which belongs to the field of solar energy application and is used for real-time dynamic tracing of the sun orientation of a solar energy concentrating and collecting system and a solar energy photovoltaic power generating system. The rotary luffing sun tracker is characterized by consisting of a two-coordinate high-precision sun tracing sensor 1, a rigid bearing platform 2, a set of or a pair of electrical push rods 3, a set of two-circuit electrical equipment driving systems 4 and a set of electric horizontally-rotating platforms 5, wherein the two-coordinate high-precision sun tracing sensor 1 is arranged on a light facing face of the rigid bearing platform 2; the lower ends of the set of or pair of electrical push rods 3 are hinged on the platform faces of the electric horizontally-rotating platforms 5 while the upper ends are hinged with the rigid bearing platform 2; one or one group of supporting feet is fixedly connected to the platform faces of the electric horizontally-rotating platforms 5; a group of coaxial hinging supporting holes are formed on the supporting feet; and the lower abdomen of the rigid bearing platform2 is hinged with the hinging supporting holes. The rigid bearing platform 2 can be pushed to perform luffing up and down around a hinged shaft of the electric horizontally rotating platforms 5 on the platform faces of the electric horizontally rotating platforms 5 at an angle of within 90 degrees through the up and down movement of moveable sleeves of the electrical push rods 3; and then the electric horizontally rotating platforms 5 carry the rigid bearing platform 2 to trace the sun motion in all directions through the rotation of the electric horizontally-rotating platforms 5 in the horizontal direction so that the light receiving face of the rotary luffing sun tracker always faces the sun.

Description

Technical field [0001] The invention is a rotating and pitching sun tracker, which belongs to the field of solar energy application, and is used for tracking and collecting solar energy by solar heat collection and heat collection systems and solar photovoltaic power generation systems, especially indispensable for solar energy high-magnification concentrating collection systems. Real-time dynamic tracking of equipment. Background technique [0002] Today, when the global fossil energy is about to be exhausted, the in-depth development and application of solar energy has attracted people's attention. But in the past, people only developed some basic products in the field of low-temperature application of solar energy, such as solar water heaters, solar photovoltaic cells and other products that do not have high requirements for tracking or basically do not need tracking. Mature, so tracking technology is not widely used. Today, people have gone deep into the research and d...

Problems solved by technology

[0003] In the existing technology, the sun tracker always adopts the "pivot drive" structure of "rotating central column + circular arc gear" like the common satellite receiving antenna type, resulting in large equipment structure, high cost and poor wind resistance , It needs a large power drive, so that it cannot be popularized and used, which creates an insurmountable barrier to the high temperature application of solar energy
