Description

Technical Field

[0001] This utility model belongs to the field of solar collector technology, specifically relating to a circulating solar collector. Background Technology

[0002] A solar collector is a device that converts solar radiation energy into heat energy. It is a key component of a solar thermal utilization system. It absorbs solar radiation and generates heat energy, which is then transferred to a heat transfer medium. According to type, it can be divided into flat plate collectors, evacuated tube collectors, etc. It is widely used in solar water heaters, solar power plants and other fields. Solar collectors have the advantages of environmental protection and energy saving, and are of great significance to promoting the utilization of renewable energy.

[0003] When using a circulating solar collector to heat water, the water source is sent to the storage tank through pipes. Sunlight shines on the collector pipes, heating the volatile liquid inside the pipes. The volatile liquid vaporizes and enters the storage tank. The volatile gas comes into contact with the water source and heats it. After the water source absorbs the heat, the volatile gas condenses and returns to a liquid state, returning to the collector pipes. The sunlight continues to heat the water source inside the storage tank in a circulating manner. However, the existing storage tanks lack an agitation structure, resulting in uneven heating of the water source inside. To address the above problems, a new circulating solar collector is proposed.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4This is a schematic diagram of the circulating solar collector structure in this embodiment. The circulating solar collector in this embodiment includes: an assembly frame 1, a collector body 2, a lower cylindrical shell 3, and an upper cylindrical shell 4. The assembly frame 1 is an inclined support structure. The collector body 2 is installed equidistantly on the assembly frame 1.

A reciprocating agitation mechanism 5 for stirring the water source is installed inside the upper cylindrical shell 4. The reciprocating agitation mechanism 5 includes a reciprocating seat 51, a reciprocating screw 52, ​​a drive motor 53, a movable block 54, an agitating impeller 55, and a rack 56.
