Has been.

  Thus, in this conventional apparatus, a permanent magnet is disposed on the lower side of the flow path, and the permanent magnet is rotated in the circumferential direction along the flow path to attract and circulate the operating body from the outside of the flow path. It was a structure to let you.

Therefore, in the conventional apparatus, when the rotational speed of the permanent magnet is increased in order to increase the power generation, the operating body may not be able to follow the movement.
As a result, when the conventional apparatus is used, there is a problem in that the rotational energy of the permanent magnet is lost, and the water pressure cannot be reliably increased by the operating body.

Further, the conventional apparatus is configured such that the operating body passes through a position slightly separated from the water wheel.
Therefore, according to the conventional apparatus, there has been a problem that the water pressure cannot be efficiently transmitted to the blades of the water turbine without loss, and as a result, the power generation efficiency is poor.

  Further, in the conventional device, an operating device that rotates the operating body is provided below the flow path. Therefore, in the case of the conventional apparatus, there has been a problem that the height cannot be avoided, the occupied space of the apparatus is wide, and the increase cannot be avoided.
