Groove type fused salt heat storage device

The invention relates to the technical field of heat storage devices, in particular to a groove type fused salt heat storage device which comprises a heat storage assembly, a heat exchange assembly and a heat exchange assembly. The two ends of the mirror field are connected to the cold salt tank and the hot salt tank through pipelines correspondingly, and the mirror field is used for heating the low-temperature fused salt through sunlight; the superheater is used for reacting with the fused salt and the steam in the hot salt tank to generate superheated steam; the power generation assembly is used for converting steam generated by the superheater into electric energy; the adjusting assembly comprises a rotating mechanism and a heating mechanism; fused salt from the superheater to the cold salt tank is continuously heated and turned over through the rotating mechanism and the heating mechanism, the fused salt close to the outer wall of the first pipeline can be stirred to the inner side of the first pipeline i
