The bracket is fixed and does not rotate, and the supporting wheel on the bracket supports the rolling ring on the shell to support the shell. Since the supporting wheel rolls relative to the rolling ring, driven by the driving wheel, other supporting wheels are driven to roll in the rolling ring, thereby driving the shell The body rotates, and the shell and the heat storage body are connected as a whole, so the heat storage body is also driven to rotate by the supporting wheel. Compared with the rotary heat storage device, which uses the support wheel to drive the heat storage body to rotate, the structure is simplified and the installation is more convenient.

The invention is simple in structure, easy to install, does not need a high-temperature-resistant central shaft, and the heat storage body is driven to rotate by the relative rolling of the supporting wheel outside the shell and the rolling ring, which reduces the heat storage device without affecting the performance of the heat storage device. The manufacturing cost is reduced, and the service life of the heat storage device is improved.
