Array type heat collecting device and control method thereof

Abstract

The invention relates to an array type heat collecting device and a control method thereof, and belongs to the field of solar heat utilization. The array type heat collecting device comprises a plurality of heat collectors and a driving system, wherein the heat collectors are distributed in an arrayed manner; the driving system comprises a power unit, a shaft transmission unit and a plurality of adjusting units; an input end of the shaft transmission unit is connected with an output end of the power unit; each adjusting unit comprises a clutch transmission structure, a first speed reducer and an output shaft; input ends of the clutch transmission structures are connected with an output end of the shaft transmission unit; output ends of the clutch transmission structures are connected with input ends of the first speed reducers through the output shafts; and the output ends of the first speed reducers are connected with the heat collectors. By the driving system of the array type heat collecting device, rotating power is provided for the rows of heat collectors through the power unit; the structure of the driving system is simplified; the cost is saved; and control on an optional row of heat collectors can be randomly stopped but control on the other rows of heat collectors is not affected.

Description

technical field [0001] The invention relates to an array type heat collecting device, which belongs to the field of solar heat utilization, in particular to an array type solar heat collecting device and a control method thereof. Background technique [0002] Solar energy is a clean energy source with a wide range of sources. The use of temperature, light and heat can be applied to heat-consuming fields such as industry and agriculture at 80-250°C, and its high-temperature light-to-heat utilization can be applied to solar power generation technology at 250-800°C. [0003] Solar collectors are the key components of various solar heat utilization systems. Whether it is solar water heaters, solar cookers, active solar houses, solar greenhouses or solar drying, solar industrial heating, solar thermal power generation, etc., solar collectors are inseparable, and solar collectors are used as the power or core components of the system. . [0004] When the user has a large demand ...

AI Technical Summary

Problems solved by technology

Since the solar collector needs to adjust the orientation of the concentrator during use, the solar collector needs to be equipped with a drive system to drive the concentrator to change its orientation. The existing array solar collectors are equipped in a one-to-one form Drive system, that is, a row of collectors is equipped with a drive system, and each drive system needs to be equipped with power units and control components, etc., which makes the overall drive system of the entire array collector complex in structure, large in floor space, and requires multiple The control cabinet is used for control, which wastes manpower and material resources

[0005] This shows that the above-mentioned existing heat collector drive system obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.
