PURPOSE: A fluid blade is provided to minimize damage to components including a blade even when the intensity of fluid increases in a place where difference between the rise and fall of the tide is large. CONSTITUTION: A fluid blade comprises a ring-shaped housing(100), a rotary body(200), a rotary shaft(300), a vane position control module, a coil, and a magnet. A vane is mounted on the side of the rotary body. The rotary shaft comprises an elongated groove for turning a vane and a space for the rotary body. The vane of the rotary body is exposed to the outside through the elongated groove. The space for the rotary body is formed inside the elongated groove. The vane position controlling module rotates the rotary body to a safety position when the intensity of fluid which bumps against the vane is high. The vane position controlling module reversely rotatesto a fluid power generation position in case the intensity of fluid is low. The magnet is placed at a position corresponding to the coil and installed in the end of the rotary shaft. |
