Embodiment 1

[0022] The solar tower power generation mirror field heliostat group control device of the present invention includes each heliostat azimuth control drive mechanism, each heliostat pitch transmission mechanism, and pitch control drive mechanism.

[0023] Such as Figure 4 As shown, the azimuth control drive mechanism can adopt a motor (not shown) fixed on the upper end of the support 13, which is movably connected with the apex of the heliostat through the pitch axis 12; the support 13 is vertically fixed on the ground . The motor rotates to drive the heliostat 11 to rotate around the axis of the bracket 13 through the pitch shaft 12 .

[0024] Such as Figure 4 , Figure 5a As shown, the pitch transmission mechanism of the heliostat includes a mirror body connecting rod 14, an arc-shaped slider 16, an arc-shaped guide rail 17, a vertically moving slider 21, a vertical guide rail 20, a slider connecting rod 18, and a rocker 19; One end of the connecting rod 14 is movably c...

Abstract

The invention relates to a heliostat grouping control device in a heliostat field of a solar tower power plant, wherein an azimuth control driving mechanism of the device provided by the invention is installed at the upper end of a bracket; the bracket is vertically fixed on the ground; the peaks of heliostats are flexibly connected with the azimuth control driving mechanism through a pitching axis; the azimuth control driving mechanism drives the heliostats to synchronously track the azimuth angle of the sun to operate through the pitching axis; the pitching motors of pitching control driving mechanisms drive transmission wheels to rotate, thereby driving transmission rods to make a push-pull reciprocating movement; and power is transferred to the heliostats through the pitching transmission mechanism of each heliostat, thereby driving each heliostat to finish a pitching movement. The heliostat grouping control device provided by the invention adopts a single pitching control driving mechanism to control a group of heliostats which are longitudinally arranged, thereby realizing the pitching tracking of the sun, and the number of the pitching control driving mechanisms is reduced by N-1 (N shows the number of heliostats in the same line), thereby reducing the control cost of the heliostat field.

Description

technical field [0001] The invention belongs to the field of solar energy utilization, and relates to a grouping control device for heliostats in a concentrating field of a large-scale solar power generation system, in particular to a grouping control device for heliostats in a solar tower-type power generation mirror field. Background technique [0002] Concentrating solar power (CSP) technology uses concentrating devices to track and condense solar radiation and convert it into high-temperature heat energy for thermal power generation. Concentrating solar power generation technology has high photoelectric conversion efficiency, and with the expansion of scale, the cost of power generation can be further reduced, so it has a good development prospect. At present, the forms of concentrating solar thermal power generation mainly include trough type, dish type and tower type. The trough-type concentrating power generation technology uses a parabolic cylindrical reflective con...
