Abstract

The invention discloses a linear Fresnel solar energy tracking driving control device. The device comprises: one group of power driving devices, multigroup fixed angle positioning devices and a connecting rod transmission apparatus. The power driving devices comprises: driving motors and automatic control systems. The control systems control workings of the motors according to a special compiled code program so as to drive a reflector group to track the sun. The angle positioning devices are used to determine initial angles of the different reflector groups. The connecting rod transmission comprises: a rigid connecting rod, a spindle sleeve slide bar and multiple groups of angle adjusting apparatuses. Therefore, multigroup reflective mirror linkage can be realized and the sun can be accurately tracked. In the invention, tracking precision is accurate; control is simple and reliable; a transmission efficiency is high; installation is simple and costs are low. And the device has many other advantages.

Description

technical field [0001] The invention belongs to the technical field of solar energy utilization, and discloses a linear Fresnel solar reflection focus tracking drive control device. Background technique [0002] Linear Fresnel Reflector (LFR) includes a linear reflector field and a receiver. These linear reflectors are arranged in parallel adjacent rows, and these reflectors can be driven by tracking means to track the movement of the sun. The sunlight reflected by the reflectors is concentrated and reflected into a receiver arranged above the reflectors, through which the solar energy is converted into thermal energy or electrical energy. [0003] The reflector in the linear Fresnel solar energy utilization system is composed of multiple reflectors, and each reflector is set at a different angle, so as to reflect and gather approximately parallel sunlight into the receiver. As the sun moves, all mirrors need to rotate to track the sun. The tracking accuracy of the mirror...
