<p>PURPOSE:To use a sailing device as a wind-driven generator when the equipment is at anchor and as a sailing device when the equipment is taken in tow by providing blades and sails on a rotary body. CONSTITUTION:When the equipment is at anchor, a winding drum is rotated and the sails 20 are stored in a horizontal member 15. When the blades 19 receive wind presure, the rotary body 18 rotates and when a clutch 13 is connected, the rotation of the rotary body 18 is transmitted to an electromotor-generator 1 through bevel gears 9, 10 and a transmission 3. Therefore, generation is conducted and electric power is supplied to a batery. When the ship is taken in tow, the winding drum is turned back to spread the sail 20. When the power of the battery or the generator is supplied to the electromotor generator 1, the rotary body 18 rotates, the transmission 3 changes into a reduction gear and the rotary body 18 rotates at a low speed. Then, when the rotary body 18 is rotated up to a desired position to cut the electric power source in conformity to the wind direction, the rotary body 18 stops and an electromagnetic brake 4 works and therefore, the rotation of the rotary body 18 is braked and fixed at the desired position.</p> |
