An azimuth tracking system using solar heat collection

Abstract

An orientation-tracking heat collection system utilizing sunlight comprises a plurality of concentric rotating plates, a motor, a plurality of reflection devices and vacuum pipe sets, wherein the radiuses of the rotating plates are different, the motor drives the rotating plates to rotate synchronously, the reflection devices are hinged to the rotating plates and the vacuum pipe sets are arranged in the internal space of the rotating plates. A water inlet pipe extending into the bottom of the internal cavity of the vacuum pipe is arranged in the vacuum pipe, arranged at the head end, in the inner ring of each rotating plate, and water inlet pipes in the inner rings of the different rotating plates are connected to a water pump after being combined. An output pipe used for outputting hot water or steam is arranged in the vacuum pipe, arranged at the tail end, in the inner ring of each rotating plate, and output pipes in the inner rings of the different rotating plates are connected to an energy storage tank after being combined. The rotating plates are mutually connected through crossed connecting rods. Rails and supporting wheels installed on the rails are arranged on the lower end surfaces of the rotating plates. According to the invention, by regulating the included angle between the light-toward surface of reflectors in the reflection devices and the horizon and driving the rotating plates to rotate through the motor, the sunlight can be utilized in a tracking mode, and the solar energy can be obtained to the maximum degree.

Description

technical field [0001] The invention relates to a solar energy tracking utilization technology, in particular to an azimuth tracking utilization solar heat collection system. Background technique [0002] my country has a vast territory and abundant solar energy resources. It is estimated that the annual solar radiation energy received by the land surface of our country is about 50×10 18 KJ, the total annual solar radiation across the country reaches 335-837KJ / cm 2 A, the median value is 586KJ / cm 2 ·A. From the perspective of the distribution of total annual solar radiation in the country, Tibet, Qinghai, Xinjiang, southern Inner Mongolia, Shanxi, northern Shaanxi, Hebei, Shandong, Liaoning, western Jilin, central and southwestern Yunnan, southeastern Guangdong, southeastern Fujian, and Hainan The total amount of solar radiation in vast areas such as the east and west of the island and the southwestern part of Taiwan Province is very large. In particular, the Qinghai-Tib...
