The present invention relates to a water flow detecting device capable of monitoring water flow in a pipe. More particularly, the present invention relates to a water flow detecting device having a lamp of a self power generation type to indicate the flow of water with a self power generation type without a separate power source. The present invention is to provide a water flow detecting device which can be simply installed to a pipe. The present invention includes: a rotation unit which is rotated by the flow of water, and a permanent magnet generation unit which generates power by the torque of the rotation unit. Thereby, the present invention is to provide a water flow detecting device having a display unit of a self power generation type by using water flow in a pipe. |
