Description

Technical Field

[0001] The utility model relates to the technical field of trough type solar power generation, in particular to a trough type collector heat preservation simulation device. Background Art

[0002] The inlet and outlet of the trough collector are connected to the collector tube. Generally, three ball heads are used to form a connecting rod mechanism. The ball heads can rotate, and then the connecting rod mechanism can rotate with the collector. Because the inlet and outlet connecting rod mechanisms of the trough collector need to rotate with the collector, and because the collector tube expands, the expansion can reach several hundred millimeters. The connecting rod mechanism hydraulically moves outward along the axial direction of the collector tube to compensate for the expansion of the collector tube. Therefore, the insulation of the connecting rod mechanism is also relatively special, especially the insulation of the ball head part. During the movement of the collector, it cannot interfere with the insulation of the elbows on both sides, otherwise the insulation of the ball head part will easily break. Generally, the collector insulation must be installed on the collector for movement testing before manufacturing to ensure that the insulation can operate for a long time. Utility Model Content
