The arrangement positions of the strip-shaped convex part (501) and the strip-shaped concave part (502) on the two hybrid heat storage half-tanks (5) are opposite, and the strip-shaped convex part (501) and the strip-shaped concave part (502) can be docked with each other.

8. The low-melting-point molten salt hybrid heat storage device according to claim 1, characterized in that Sealing gaskets (503) are further arranged at the mutually contacting ends of the two hybrid heat storage half-tanks (5).

9. The low-melting-point molten salt hybrid heat storage device according to claim 1, characterized in that A sealing plate (303) is further arranged on the side of the fixing plate (302) for fitting and contacting with the hybrid heat storage half-tank (5).

10. A working method of the low-melting-point molten salt hybrid heat storage device according to claim 1, characterized in that, It includes: When adding raw materials, the two mixing heat storage semi-tanks (5) are closed under the drive of the adjusting bracket assembly (4), and one end of the two closed mixing heat storage semi-tanks (5) is sealed by the fixed plate (302); driven by the angle adjusting assembly (2), the top plate (3) rotates around the first selected middle part, and the top plate (3) is lifted so that the open ends of the two closed mixing heat storage semi-tanks (5) are vertical or inclined upward, and raw materials are added from the open ends and the cover (7) is installed; When stirring the raw materials, driven by the angle adjusting assembly (2), the top plate (3) rotates around the first selected middle part to lay the mixing heat storage semi-tank (5) flat; the rotating motor (6) drives the spiral stirring rod (603) to rotate and stir the raw materials; the third driving member (701) drives the rotating disc (702) to rotate, and then drives the turning plate (703) to rotate to turn the raw materials, and the rotation direction of the turning plate (703) is opposite to the rotation direction of the spiral stirring rod (603) to prevent the raw materials from stacking; During the cleaning process, the two mixing heat storage semi-tanks (5) are separated under the drive of the adjusting bracket assembly (4), and the inner walls of the two mixing heat storage semi-tanks (5) and the spiral stirring rod (603) are cleaned.
