Sand proof curtain for secondary reflection tower and lifting system of sand proof curtain

Abstract

The invention relates to a sand proof curtain for a secondary reflection tower and a lifting system of the sand proof curtain. The sand proof curtain comprises a sand proof net and an annular gripping apparatus, wherein the sand proof net comprises a cylinder type sand proof net part and a funnel type sand proof net part; the funnel type sand proof net part is positioned at the upper end of the cylinder type sand proof net part; the annular gripping apparatus is positioned between the cylinder type sand proof net part and the funnel type sand proof net part; the lifting system comprises hoisters, fixed pulleys, hoisting steel cables and guide rails; the hoisters are mounted below vertical columns of the secondary reflection tower; the corresponding fixed pulleys are mounted at the top ends of the vertical columns; the guide rails are arranged on one side, corresponding to the annular gripping apparatus, of each of the vertical columns; one end of each of the hoisting steel cables is coiled up through the hoisters, and the other ends of the hoisting steel cables run over the fixed pulleys to be connected with steel cable joints on the annular gripping apparatus. According to the sand proof curtain for the secondary reflection tower and the lifting system of the sand proof curtain, the structure is simple, the design is reasonable, the occupied space is small, the operation is easy, and the sand proof effect is good.

Description

technical field [0001] The invention relates to an anti-sand curtain for a secondary reflection tower and a lifting system thereof, belonging to the technical field of anti-sand of a secondary reflection tower. Background technique [0002] Solar thermal power plants are generally built in areas rich in solar energy resources. These areas are concentrated in central and western China and are often areas where sandstorms frequently occur. Sandstorm is a general term for both sandstorm and dust storm. It refers to a weather phenomenon in which a large amount of sand and dust on the ground is swept into the air by strong winds, making the air particularly turbid, and the horizontal visibility is lower than 1Km. Among them, a sandstorm refers to a sand-carrying storm formed by strong winds blowing a large amount of sand particles into the air layer near the ground, and a dust storm is a storm formed by high winds that drag a large amount of dust and other fine-grained materials ...

AI Technical Summary

Problems solved by technology

The reflective material used in the secondary reflection tower is mainly aluminum, and its surface hardness will be shortened under the influence of high-intensity dust storms
