Dish type solar tracking and direction angle driving system

Abstract

The invention discloses a dish type solar tracking and direction angle driving system which comprises a receiver, a protective board, at least three thermocouple temperature sensors, a central control unit, a direction angle sensor, a direction angle driving mechanism, a GPS (Global Position System) module, a power supply and a direction angle gear transmission mechanism, wherein the direction angle driving mechanism is used for driving the direction angle gear transmission mechanism and provided with at least two driving motors; and the thermocouple temperature sensors are distributed on theprotective board and arranged in a circular shape by taking a receiving port of the receiver as a center, and at least three thermocouple temperature sensors are arranged on each circle. The dish type solar tracking and direction angle driving system has the advantages of high reaction speed, high tracking precision, low cost, working stability of the driving part thereof, strong shock resistance, large transmission torque and long service life.

Description

technical field [0001] The invention relates to a dish type solar tracking and azimuth driving system. Background technique [0002] Solar thermal power generation has attracted widespread attention around the world because its power generation method is similar to the traditional power generation method, easy to connect to the grid, and easy to promote on a large scale. There are four main types of solar thermal power generation: solar trough power generation, solar tower power generation, solar dish power generation, and solar chimney power generation. Solar dish power generation is a method with the highest photoelectric conversion efficiency among solar thermal power generation methods. At the same time, it has the characteristics of standardized production and high flexibility. It will have a lot of room for development in the future. The incident sunlight is focused into the receiver through the rotating parabolic butterfly concentrator, the working fluid is heated, a...

However, these technologies are all tracking at non-focus points, which cannot reflect the actual working conditions of the focus points in real time, which will lead to shortcomings such as slow tracking response speed and low tracking accuracy.

[0003] At present, most of the traditional gear transmission mechanisms use a single driving gear to drive a single or multiple driven gears, and are widely used to transmit power and reducers. There are many types, different models, and a wide range of applications. With the scientific With the continuous development of technology and the improvement of production level, ordinary gear transmission can no longer meet people's use requirements due to the shortcomings of small number of contact teeth, unstable work, weak impact resistance, small transmission torque and short service life.
