  • Patent number: 11365905
    Abstract: An energy concentrating apparatus includes: a mounting platform, a mounting support, a rotating support, a reflective mirror, an arc-shaped slide rail, a linking rod, a sliding parts, a drive device, and a pull rope. The mounting support is located on the mounting platform. A rotation shaft of each rotating support is rotatably located on the corresponding mounting support, and a rotation shaft of each reflective mirror is rotatably located on the corresponding rotating support. The arc-shaped slide rail is located on the mounting platform, and the sliding parts is slidably located in the arc-shaped slide rail, the linking rod is connected to the sliding parts and the reflective mirror respectively, and a curvature of the arc-shaped slide rail is different such that the reflective mirror rotates towards a different direction.
