Tracing transmission mechanism suitable for solar concentrating system

Abstract

The invention relates to a tracing transmission mechanism suitable for a solar concentrating system. A centring round rail is arranged at the bottom of a horizontal rotating disc, a driving friction wheel and driven friction wheels are movably connected with the centring round rail, and a pitching mechanism is arranged above the horizontal rotating disc. The tracing transmission mechanism further comprises a friction wheel height adjusting device connected with the driving friction wheel. Friction between the driving friction wheel and the centring round rail is used for driving the horizontal rotating disc to rotate, and therefore the motor is prevented from burning out; the pitching mechanism is used for adjusting the orientation of a solar concentrating mirror; the friction wheel height adjusting device prevents the driving friction wheel from falling off the centring round rail by adjusting the height of the driving friction wheel; the horizontal rotating disc is used for adjusting the horizontal direction of the concentrating mirror to trace the azimuth angle of the sun, the pitching mechanism is used for adjusting the vertical angle of the concentrating mirror to trace the elevation angle of the sun, and by means of the cooperation of the horizontal rotating disc and the pitching mechanism, sunlight is radiated perpendicularly to achieve photovoltaic conversion at the maximum efficiency.

Description

technical field [0001] The invention relates to the technical field of solar energy, and is especially suitable for a tracking transmission mechanism of a solar concentrating system. Background technique [0002] A concentrated solar system consists of two main devices: a concentrated solar module and a tracker. The tracker includes a transmission mechanism and an electric control part. The electric control part controls the movement of the transmission mechanism, and the transmission mechanism drives the solar concentrator to move, so that the mirror surface of the solar concentrator faces the sun, and the sunlight is concentrated on the focus of the mirror. The orientation of the solar concentrator conforms to the trajectory of the sun through the tracker. Existing tracking transmission mechanism adopts chain or gear transmission mechanism. The matching clearance of the chain or the gear transmission mechanism is large, and the vibration of the tracking transmission mec...

AI Technical Summary

Problems solved by technology

However, in the above technical solution, the motor directly drives the rotating disk to rotate. If the rotating disk is overloaded, it is easy to burn out the motor.

[0004] It can be seen that the tracking transmission mechanism applicable to the solar concentrating system in the prior art has the following defects: the tracking transmission mechanism cannot be overloaded, and the tracking transmission mechanism is prone to failure
