Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] Such as figure 1 , figure 2 As shown, the special-shaped heliostat of the present invention is composed of a heliostat unit reflector 1, a third vertical support 2, a second vertical support 3, a first vertical support 4, a column 5, a transmission box 6, a horizontal shaft 7, and a fourth The vertical support is composed of 8 etc. Wherein, there are two pieces of the second vertical support 3, the first vertical support 4 and the horizontal shaft 7 respectively.

[0021] The column 5 is connected to the foundation through anchor bolts. The transmission case 6 is installed on the column 5, and is connected with the upper flange of the column 5 by bolts. The transmission box 6 can move along two directions of azimuth and pitch, accurately track the rotation of the sun around the clock, and the tracking accuracy is better than 3mrd. ...

Abstract

The invention provides a solar tower-type thermal power generation special-shaped heliostat which comprises a heliostat unit reflector (1), longitudinal supports, a column (5) and a transmission box (6). The transmission box (6) is arranged on the upper flange of the column (5). Two sides of the transmission box (6) are provided with a horizontal shaft respectively. Two first longitudinal supports (4) are respectively arranged on left and right horizontal shafts (6), and are bilaterally symmetrical along the horizontal rotation center of the heliostat on one side close to the transmission box (6). Two second longitudinal supports (3) are respectively arranged on left and right horizontal shafts, are close to the first longitudinal supports (4), and are bilaterally symmetrical along the horizontal rotation center of the heliostat on the outer side of the first longitudinal supports (4). The third longitudinal support (2) and the fourth longitudinal support (8) are symmetrically arranged on the outermost sides of left and right horizontal shafts, and are bilaterally symmetrical along the horizontal rotation center of the heliostat. The outer contour of a truss formed by all longitudinal supports is an isosceles triangle. The heliostat unit reflector (1) is arranged on the truss formed by all longitudinal supports.

Description

technical field [0001] The invention relates to a solar tower type thermal power generation heliostat. Background technique [0002] The energy crisis is becoming increasingly prominent worldwide, and renewable energy will become an important part of the world's energy structure in the future. Especially, it is of great significance to the rational development of solar energy utilization. In recent years, scientific researchers from various countries in the world have carried out a lot of work and scientific exploration in this area, and have achieved remarkable results. Solar thermal power generation is the most typical representative. At present, the forms of solar thermal power generation system mainly include: solar tower type, solar trough type, solar dish type and solar Fresnel type and so on. Among them, the solar trough concentrating system is the main form of solar thermal power generation adopted in recent years. It is the earliest form of solar thermal power ge...
