Mirror board support device of solar trough type power generation system

Abstract

The invention discloses a mirror board support device of a solar trough type power generation system, which comprises a grider brace and a reflector supporting structure, wherein the reflector supporting structure is arranged on the grider brace through rotating parts which are arranged on two ends of the reflector supporting structure, and can rotate around axial lines of the rotating parts under the drive of an external drive device; the reflector support structure comprises a plurality of grider framework units which are connected end to end, and arc supporting parts for supporting a reflector mirror are arranged on two ends of each grider framework unit. The mirror board support device of the solar trough type power generation system has the advantages that: 1) each main member can be produced in a factory standardization manner; 2) mechanical bending resistance and torsional properties of the grider framework structures are reasonable, and materials are saved; 3) connection quantity of field bolts is little, assembly errors are favorably controlled, and assembly accuracy is higher.

Description

technical field [0001] The invention relates to a support device for a mirror panel of a trough power generation system. Background technique [0002] Such as figure 1 As shown, the trough-type parabolic heat collection system is a line focusing system composed of many reflectors 101 whose cross-section is parabola, the length direction is a trough, and the focus of the parabola is a straight line along the length direction. The incident sunlight 102 is reflected by the reflective mirror 101 and then concentrated on the focal point 103 of the reflective mirror. The trough parabolic heat collection system uses concentrated solar energy to heat the heat transfer medium in the heat collector, and generates steam in the heat exchanger to drive the steam turbine to generate electricity. Many trough concentrators can be distributed and arranged in series or parallel to form a trough mirror array, and the capacity of the mirror array system can be set according to requirements. ...
