Auto-focusing system of solar cooker

Abstract

The invention discloses an auto-focusing system of a solar cooker, belonging to the technical field of clean energy. A central axis sleeve and a control box are fixed at a base plate, a horizontal rotation axis is inserted into the central axis sleeve, a mechanical leg or other horizontal rotation devices are fixed at the horizontal rotation axis, a luffing motion mechanism is fixed at the top end of the horizontal rotation axis, a luffing motion drive motor is arranged on a luffing motor mounting board at one side of a luffing motion bracket of the solar cooker, and a luffing rotation axis for mounting the solar cooker and a solar cell plate is propped in the bearing of luffing motion bracket. The invention adopts a brand-new mechanism and a motion mode, simultaneously, adopts the solar cell to trace the system power supply and keeps the synchronous sun tracing state of the solar cell and the solar cooker so as to facilitate the solar cell to play in full swing. When the solar cookeris unused or the light condition is poor, the system does not work to reduce energy consumption at utmost. The energy collected by the solar cell can be stored in a storage cell.

Description

technical field [0001] The invention belongs to the technical field of clean energy, and in particular relates to an automatic light alignment system for a solar cooker. Background technique [0002] Most of the existing solar cookers on the market are manual solar cookers that require manual adjustment of the angle of rotation to focus. When using a manual solar cooker, people must detect the orientation of the sun and manually adjust the inclination angle of the reflector of the solar cooker to keep the spot of the reflector within the designated heating area. Manual operation is often required during use, which is very inconvenient; at the same time, the working accuracy of the solar cooker is largely affected by human factors. [0003] At present, sporadic single-axis or double-axis tracking solar cookers have entered the market. However, the results of a certain period of use show that many tracking solar cookers, even manual solar cookers, have unstable mechanical st...

AI Technical Summary

Problems solved by technology

However, the results of a certain period of use show that many tracking solar cookers, even manual solar cookers, have unstable mechanical structures, mechanical devices are prone to corrosion and rust, and have a short service life. Problems such as high cost have brought certain difficulties to the large-scale popularization of solar cookers

In addition, most of the power supply methods of the tracking system choose an external power supply line or use a battery. Install the battery during the day and charge the battery at night or when the tracking solar cooker is not in use; The solar cell is installed in a fixed way, because the photoelectric conversion efficiency of the solar cell is greatly affected by the incident angle of the sun's rays, so the solar cell does not achieve a better use effect
