Groove type solar heat collection field arrangement method and heat collector adjusting device

Abstract

The invention relates to a groove type solar heat collection field arrangement method, which belongs to the field of solar power generation. The method comprises the following steps that S1, a solar incident angle is calculated, and a loop number proportion is determined; and S2, the groove type heat collector is arranged, tracking shafts are arranged in the south-north horizontal mode and the east-west horizontal mode respectively during arrangement, and the number proportion of the south-north horizontal arrangement and the east-west horizontal arrangement is the same as the number proportion of loops. A heat collector adjusting device comprises a heat collector mirror surface, a mounting frame for mounting the heat collector mirror surface, a rotating shaft arranged on the mounting frame and supporting frames arranged at the two ends of the rotating shaft, and further comprises adjusting assemblies arranged on the supporting frames, and each adjusting assembly comprises a supporting seat and a hydraulic cylinder hinged to the supporting seat; the end of the mounting frame is fixedly connected with a swing plate, and the end, away from the mounting frame, of the swing plate is hinged to a piston rod of the hydraulic cylinder. The device has the effects of stabilizing the output energy of the heat collector and improving the circulation efficiency of the trough type solar heat power generation system.

Description

technical field [0001] The present application relates to the field of solar power generation, in particular to a method for arranging a trough-type solar heat collection field and a heat collector adjusting device. Background technique [0002] The trough heat collection system uses the trough parabolic concentrating reflector to collect the solar radiation energy with high heat flux density to realize the light-to-heat conversion process of the system. Sunlight incident on the earth's surface through the atmosphere will produce radiant energy with low heat flux density, direct use will affect its economy, and only by gathering the radiant energy with low heat flux density can it be converted into radiant energy with high heat flux density. From the analysis of optical theory, it can be known that parabolic concentrator is a line shape that can converge a beam of parallel light to a point. Therefore, parabolic concentrating has become a very common form of concentrating, a...

Problems solved by technology

[0003] In view of the above-mentioned related technologies, the inventor believes that the current layout of the trough solar heat collection field is widely used in the north-south direction or the east-west direction, but only in a single direction. This single layout has limitations and may easily lead to The energy output of the thermal field is unstable, which in turn affects the cycle efficiency of the trough solar thermal power generation system
