Embodiment Construction

[0038] Such as figure 2 As shown, the axis 3 of the main support structure of the parabolic trough concentrator is parallel to the axis of rotation 5 of the parabolic trough concentrator, and they are in the same plane, which is the central plane 7 of the main support structure; The central plane 14 is symmetrical with two mirror arm fixing plates 11 forming a mirror arm mounting point 12 . Such as figure 1 As shown, the support structure of the parabolic trough concentrator consists of the main support structure 1 and twenty-eight on both sides of the main support structure 1, and at the mirror arm mounting point 12, the reflector arm fixing plate 11 is connected to the main The support structure 1 is formed by the mirror support arm 6 connected.

[0039] image 3 For the assembled parabolic trough concentrator, the inner sub-mirror 8-1 of the parabolic reflector and the outer sub-mirror 8-2 of the parabolic reflector are installed on the supporting structure of the assem...

Abstract

Provided is a paraboloid groove type condenser assembling method. For an existing paraboloid groove type condenser, positions of reflector supporting arms (6), relative to a main supporting structure (1), are confirmed, and shapes of supporting arm templates (16), and positions of the supporting arm templates (16), relative to the main supporting structure (1) can be confirmed, wherein bottom edge shapes of the supporting arm templates (16) are the same as upper edge shapes of the reflector supporting arms (6). When the supporting arm templates (16) keep the positions relative to the main supporting structure (1) and move from one end of the main supporting structure (1) to the other end of the main supporting structure (1) along the main supporting structure axis (3), the reflector supporting arms (6) and the supporting arm templates (16) are tightly attached and aligned to one another and connected with the main supporting structure (1) at reflector supporting arm mounting points (12) of the main supporting structure (1), all the reflector supporting arms (6) are installed at required positions, parabolic reflector inner sub-mirrors (8-1) and parabolic reflector outer sub-mirrors (8-2) are installed on the reflector supporting arms (6), and the paraboloid groove type condenser meeting requirements is formed.

Description

technical field [0001] The invention relates to an assembly method of a parabolic trough concentrator of solar thermal power generation equipment. Background technique [0002] As a collection device for solar radiation energy, the parabolic trough concentrator is used in conjunction with the heat absorbing tube to form a parabolic trough collector, which can provide heat for solar thermal power generation. [0003] In foreign countries, trough solar thermal power generation is already a mature technology, and the construction period of trough power plants is constantly shortening. A trough solar collector field of a 50MW trough solar power plant can be completed within 2 months. This is mainly due to the fact that some foreign companies have mastered the mature trough concentrator assembly process during the 20 to 30 years of trough thermal power generation development. The Proceedings of the Solarpaces Conference in 2011 included an article "Collector assembly concept wit...
