Abstract

The invention discloses an inexpensive high-precision two-dimensional sun tracking mechanism used for concentrating to generate power. The two-dimensional sun tracking mechanism is characterized in that a one-dimensional rotating frame, a two-dimensional rotational mesosome framework, a latitude adjuster, a declination angle adjuster and a tracking deviation indicator are designed; the one-dimensional rotating frame is connected with a right-ascension axle and the two-dimensional rotational mesosome framework sleeved on an outer ring of the right-ascension axle; a carrier platform framework is divided into a south block and a north block, the two blocks are respectively connected with an upper side frame and a lower side frame of the two-dimensional rotational mesosome framework, and condensing lenses, photovoltaic cells, and the like, are installed on the carrier platform framework; and the right-ascension axle parallel to the earth axle rotates at a fixed speed and drives a carrier platform with an included angle (equal to the declination angle on the same day) with the right-ascension axle to rotate along with the sun. The two-dimensional sun tracking mechanism has the advantages of simple tracking method, high tracking accuracy, balanced deadweight of the device from all directions due to the layered and symmetrical carrier platforms, saved material, small wind resistance and driving power, low fabricating cost of the complete machine, effectively reduced cost of concentrating solar photovoltaic power generation and medium-high heat utilization device and improved efficiency.

Description

Technical field: [0001] The invention relates to the field of solar energy utilization, in particular to a sun tracking mechanism in a concentrating device. Background technique: [0002] The light density of solar energy is low. In order to obtain medium and high temperature heat and reduce the cost of fixed flat-panel solar photovoltaic power generation systems, people are actively developing various concentrating solar heat utilization and photovoltaic power generation devices. At present, there are three main types of solar concentrating devices, parabolic trough, dish and tower. Most of the parabolic trough devices adopt the one-dimensional tracking method of the sun by adjusting the declination angle arranged in the east-west direction. The solar declination angle δ is the angle between the sun’s incident ray and the equatorial plane. It is positive to the north. The summer solstice is 23.5°, the winter solstice is -23.5°, and the spring and autumn equinox is 0°. The...
