Background

In the prior art, patent document No. CN201621084840.1 provides a trough-type solar concentrator, in which a reflector support frame of the trough-type solar concentrator has a stable structure and a light weight, so that the center of gravity of the trough-type solar concentrator falls on the middle point of a truss, and the trough-type solar concentrator is driven to rotate at a constant speed by a minimum driving force in actual operation, thereby achieving the purposes of energy saving and environmental protection. The reflector support frame is horizontally provided with a first fixed cross beam and a second fixed cross beam, so that the structural strength of the reflector support frame is increased, and the first fixed cross beam and the second fixed cross beam are connected through a second connecting rod, so that the gravity from the reflector group is effectively dispersed, and the supporting effect of the reflector support frame is enhanced; secondly, the triangular structure of the reflector support frame is added, so that the structure of the reflector support frame is more stable. Although the device has more beneficial effects, the following problems still exist: solar energy has low density and interstitial properties and is not spatially distributed uniformly, and when solar radiation is directed at a horizontal collector at an oblique angle, the intensity of the solar radiation is lost to some extent, while increasing the reflective area reduces this unwanted loss. In view of this, we propose a trough solar collector with enhanced concentration.
