Differential pressure solar automatic tracking device

Abstract

The invention belongs to the field of solar tracking brackets and is suitable for solar photovoltaic inaccurate automatic tracking. The differential pressure solar automatic tracking device of the present invention includes a pressure difference generating device, a transmission mechanism, and a night reset device. The pressure difference generating device is an organic working medium metal sealing tube embedded in a parabolic groove on both sides of the middle partition and the partition. and a metal deformation actuator, and a group of gas tubes are arranged around the reflector as a tracking sensor for the time angle; the present invention aims to propose a differential pressure solar automatic tracking device, which can make the sealed organic medium expand by concentrating light through the change of the solar angle Drive the differential pressure mechanism to rotate to track the sun.

Description

Technical field [0001] The invention belongs to the field of solar tracking brackets and is suitable for inaccurate automatic tracking of solar photovoltaic. technical background [0002] In terms of sun tracking: fixed inclination, horizontal axis tracking, fixed inclination azimuth tracking, oblique single-axis (or polar axis) tracking, dual-axis tracking, etc. are often used to reduce the incident angle of light on the receiving surface. Most tracking systems realize automatic control through power electronics. The system is relatively complex and has high cost and maintenance costs. The initial investment of the single-axis tracking system is relatively small, and the structure of the tracking equipment is simple. However, because the incident light cannot always be parallel to the main optical axis, the effect of collecting solar energy is not ideal. [0003] The dual-axis tracking system can be used in any solar system to improve its operating efficiency. There are also ma...

but expensive

[0004] Existing tracking devices for observing solar activity are accurate but expensive; among them, the traditional differential pressure and control-release solar trackers have complex principles and structures; clock-based and program-controlled tracking devices have accumulated errors And it cannot be automatically eliminated; the photoelectric tracking device is more accurate in tracking, the principle is simple, and it is easy to implement, but it cannot continuously track the sun's movement, and the high price is the problem existing in the current solar tracking device
