Problems solved by technology

The structure of this solar heliostat tracking system is relatively simple, and the cost is reduced. However, the angle of the mirror frame rotating up and down on the horizontal rotation mechanism frame is 0-150°, and the reflector or photovoltaic panel on the mirror frame cannot be buckled upside down. Not conducive to reducing the accumulation of dust

Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0036] Such as figure 1 As shown, the heliostat tracking drive mechanism of the present invention consists of a horizontal axis azimuth adjustment mechanism 600 located on the upper part of the heliostat column 1, a U-shaped bracket 4 located on the upper part of the horizontal axis azimuth adjustment mechanism 600, and an electric cylinder located in the middle of the U-shaped bracket 4. 5 and the transmission box 9 positioned at the top of the U-shaped support 4 constitutes.

[0037] Such as figure 2 As shown, the U-shaped bracket 4 is formed by the first column 14 01 , the second column 14 02 And the bottom beam 15 constitutes. On the first column 14 of the U-shaped bracket 4 01 The upper part is welded with the first fixed plate 13 01 , on the second column 14 of the U-shaped bracket 4 02 The upper part is welded with a second fixed...

Abstract

A heliostat tracking drive mechanism, characterized in that: a U-shaped bracket (4) is connected to the upper part of the heliostat column (1), and a supporting right angle (601, 602) is connected to the upper part of the U-shaped bracket (4), The worm bearing cover flanges (701, 702) are respectively hinged with the support right angles (601, 602). The transmission box (9) drives the heliostat reflecting surface (50) to rotate around the pitch axis (60); the cylinder body (501) of the electric cylinder (5) is hinged to the bottom of the U-shaped bracket (4), and the electric cylinder (5) The push rod (502) is hinged to the drive fork (8), the drive fork (8) is fixedly connected to the transmission box (9), and the electric cylinder (5) drives the transmission box (9) to drive the reflective surface of the heliostat (50) around the horizontal axis (70) rotation; the heliostat realizes dual-axis tracking of the sun. After the work is finished, the electric cylinder (5) pushes the pitch axis (60) to a horizontal position, and the transmission box (9) drives the two semi-reflecting surfaces (5001, 5002) on both sides of the transmission box (9) to rotate and face the ground, reducing Dust collects on reflective surfaces.

Description

technical field [0001] The invention relates to a driving mechanism of a solar heliostat for tracking the sun. Background technique [0002] The heliostat is the concentrating device of the tower-type solar thermal power concentrating system. Its dual-axis tracking drive mechanism drives the reflective surface to reflect and concentrate sunlight to a fixed target. A heliostat is generally composed of a reflecting surface, a supporting frame, a tracking drive mechanism, and a tracking control system. [0003] Compared with thermal power generation, solar thermal power generation mainly uses concentrating heat collection systems instead of coal-fired boilers. In order to make tower-type solar thermal power generation competitive with conventional thermal power generation, reducing the cost of the heliostat itself and the operating cost of the heliostat is one of the effective means to achieve this goal. In the cost of the heliostat itself, the proportion of the tracking driv...
