Disc type solar directional tracking device

Abstract

The invention discloses a disc type solar directional tracking device that is applied to a unit for collecting the solar energy in a solar high-temperature generator set. The disc type solar directional tracking device comprises a hydraulic drive device with a control system, a plurality of groups of disc type solar units connected with the hydraulic drive device by flexible pipes. The disc type solar units contain pedestals, vertical rotating shafts arranged on the pedestals, hydraulic motors arranged at the middle parts of the vertical rotating shafts, support frames arranged at the upper ends of the vertical rotating shafts, horizontal rotating shafts arranged on the support frames, motors arranged at the outer sides of the support frames and are connected with the horizontal rotating shafts, cambered-surface-shaped disc type solar heliostats fixedly connected to the middle parts of the horizontal rotating shafts, and heat collectors matching the solar heliostats. The heat collectors are connected with the generator set by heat-transfer mediums. According to the invention, the azimuthal angles of the sun can be tracked all the time; the receiving angle can be adjusted automatically; and the solar energy can be utilized fully.

Description

technical field [0001] The invention relates to a solar energy orientation tracking device, which is used for a solar energy collecting device in a solar high temperature generating set. Background technique [0002] Energy is the driving force of social and economic development. However, a large amount of fossil energy consumption is increasingly showing unsustainability. As a new energy source, solar energy is inexhaustible and inexhaustible. The most important thing is that solar energy is a clean energy source. When it is developed and utilized, it will not produce waste residue, waste water, waste gas, nor noise, let alone affect the ecological balance. It will definitely not cause pollution or public nuisance. [0003] At present, there are three main ways of solar thermal power generation, namely tower solar thermal power generation, trough solar thermal power generation and dish solar thermal power generation, among which the dish solar energy has the highest abso...

AI Technical Summary

Problems solved by technology

In dish-type solar thermal power generation facilities, the device for collecting solar energy needs to track the change of the sun's position. In the traditional way of dish-type solar thermal power generation to collect sunlight, the solar collector can only rotate according to certain rules, and cannot rotate in the horizontal and vertical directions. They are completely aimed at the sun at all times, the collection effect is not good, and the solar energy utilization rate is low
