Description

Technical Field

[0001] The utility model relates to the technical field of solar flat-plate heat collector installation, in particular to a fixing device for a solar flat-plate heat collector. Background Art

[0002] Flat-plate solar collectors are basic components for low-temperature solar thermal utilization. They are non-concentrating components in solar thermal utilization systems that receive solar radiation and transfer heat to their heat transfer medium. Flat-plate solar collectors are mainly composed of several parts, including a heat absorbing plate, a transparent cover, an insulation layer, and an outer shell. The heat absorber structure is basically in the shape of a flat plate. When the flat-plate solar collector is working, solar radiation passes through the transparent cover and is projected onto the heat absorbing plate, where it is absorbed and converted into thermal energy. The heat is then transferred to the heat transfer medium in the heat absorbing plate, causing the temperature of the heat transfer medium to rise as useful energy output for the collector.

[0003] When installing solar flat-plate collectors in a centralized manner, they are generally moved to the top of a flat support frame, laid flat and set, and then the solar flat-plate collectors are fixed to the support frame with bolts and fasteners. However, during installation, the solar flat-plate collectors need to be moved to the support frame one by one, which is not only inefficient, but also inconvenient to move to a high place due to the large size of the solar flat-plate collectors. Therefore, the present application designs a solar flat-plate collector fixing device that improves the integrated installation efficiency of the solar flat-plate collector to solve this technical defect of the prior art.
