1. An exchangeable in-pipe power generating device comprising:
a pipe unit including a pipe body that extends along a pipe axial direction, and an opening that is disposed on said pipe body and that extends along the pipe axial direction;
a base unit including a first base portion that extends along the pipe axial direction and that is disposed in said pipe body, said first base portion being adjacent to said opening; and
a power generating unit including a plurality of power generators that is disposed on said first base portion and that is spaced apart from one another along the pipe axial direction, each of said power generators including a blade module that is rotatable about a blade axis, and a power converting module that is disposed on said first base portion and that is driven by said blade module to convert kinetic energy into electrical energy, the blade axis of each of said power generators cooperating with the pipe axial direction to form an acute angle;
wherein said opening of said pipe unit is disposed at top of said pipe body; and
wherein said power generating unit further includes a circuit board that is connected to said base unit and that is electrically coupled to said power converting module of each of said power generators, said circuit board having an outer portion that is distal from said opening, and an inner portion that is opposite to said outer portion and that is proximate to said opening.
