Embodiment Construction

[0025] The present invention will be further described in detail below with reference to the accompanying drawings, so that those skilled in the art can implement it with reference to the text of the description.

[0026] It should be understood that terms such as "having", "including" and "including" used herein do not equate the presence or addition of one or more other elements or combinations thereof.

[0027] Such as figure 1 As shown, the present invention provides a heliostat tracking control device, including:

[0028] A light concentrating device, which includes a supporting structure, a heliostat 1 arranged on the supporting structure, and a transmission system device. The light concentrating device realizes the heliostat 1 tracking through the pitch rotation and horizontal rotation of the east-west and north-south dimensions. Day tracking

[0029] The tracking device 2 includes a driving device and a sensor. The tracking device 2 is installed on the corner of the heliostat ...

Abstract

The invention discloses a heliostat tracking control device, which comprises a light concentration device and a tracking device, wherein the light concentration device comprises a supporting structure, and a heliostat and a transmission system device arranged on the supporting structure; and the tracking device comprises a driving device and sensors, the sensors comprise a time tracking sensor and a photosensitive tracking sensor, and the transmission system comprises a worm gear device and a pushing rod device. According to the heliostat tracking control device provided by the invention, through adopting the transmission system mode of combining the worm gear and the pushing rod, the time tracking sensor and the photosensitive tracking sensor are matched, problems of low precision and high price in the previous heliostat tracking are overcome, and the practical value is extremely high.

Description

Technical field [0001] The invention relates to the field of solar tracking, more specifically, the invention relates to a heliostat tracking control device. Background technique [0002] At present, there are three main methods of solar thermal power generation, namely tower solar thermal power generation, trough solar thermal power generation and butterfly solar thermal power generation. Heliostat is the core component of the concentrating device of the solar thermal power generation system and controls the entire solar power station. In the solar thermal power generation facility, the solar energy collection device needs to track the change of the sun’s position. In the traditional solar thermal power generation method to collect sunlight, there are two driving methods for the fixed mirror, namely the azimuth-tilt mirror and Spin-pitch fixed lens. Conventional azimuth-pitch heliostats use motor pulses or encoder pulses combined with the initial position angle to indirectly ca...
