Abstract

The invention relates to a two-dimensional tracking solar concentrating device, comprising: a bracket; an outer frame, which is mounted on the top of the bracket through a first bearing and can rotate relative to the bracket around an axis extending in the east-west direction; A condensing mirror with a shaped reflective surface is installed in the outer frame through a second bearing, and can be rotated relative to the outer frame around an axis extending in the north-south direction; and a solar collector tube is fixed at the focusing position of the condenser. The two-dimensional tracking solar energy concentrating device of the present invention can track sunlight in all directions, and can use a solar vacuum heat collecting tube with one end open, thereby reducing the production cost.

Description

technical field [0001] The invention relates to the field of solar energy applications, more specifically, to a two-dimensional tracking solar concentrating device. Background technique [0002] As an environmentally friendly energy source, solar energy has been widely used. At present, the tracking and concentrating devices used in solar energy are mainly trough-type parabolic tracking and concentrating devices and tower-type heliostat concentrating and concentrating devices. [0003] Most of the current trough-type parabolic concentrator tracking devices are one-dimensional tracking devices, which are usually used for solar thermal power generation. Its working condition is that the mirror usually faces south in the northern hemisphere, and the longer two mirror grooves are placed towards the east-west direction. The angle between the curved mirror surface and the horizontal line in the north-south direction is adjusted by the tracking device, so as to track the change o...
