Submersible power generator

摘要

A submersible power generator with an inner/outer double rotational armatures-type power generation mechanism provided with an outer rotational armature and an opposing inner rotational armature to rotate opposite to the outer rotational armature, and a pair of propellers, where one of the propellers is connected to one of the inner and outer rotational armatures and the other of the propellers is connected to the other armatures, and a casing for accommodating the inner/outer double rotational armatures-type power generation mechanism and shielding it from an external environment. The submersible power generator is installed under water to operate in a water current with a gravity W that is larger than buoyancy F acting thereon during operation of the submersible power generator, and makes a rotational moment center that a sum total of rotational moments generated by gravity W, buoyancy F, and drag D in a water current becomes zero.

1. A submersible power generator comprising:
relatively rotating inner and outer armatures, wherein the rotating inner and outer armatures are a double rotational armatures-type power generation mechanism provided with an outer rotational armature and an inner rotational armature opposing the outer rotational armature to rotate in a direction opposite to a direction of rotation of the outer rotational armature; a pair of propellers driving the inner and outer armatures to rotate relative to each other, wherein the pair of propellers disposed coaxially with blades of one of the pair of propellers and blades of the other of the pair of propellers twisted in opposite directions relative to an extending direction of a central axis of the pair of propellers, wherein one of the propellers is connected to one of the inner and outer rotational armatures and the other of the propellers is connected to the other of the inner and outer rotational armatures; and a casing accommodating the inner and outer armatures and shielding the inner and outer armatures from an external environment; wherein the submersible power generator is installable under water and operatable in a water current, wherein, during operation, the submersible power generator has a gravity W acting thereon that is larger than a buoyancy F acting thereon, wherein the submersible power generator, as seen on a meridian plane, forms a rotational moment center, wherein a sum total of rotational moments generated by the gravity W acting thereon, the buoyancy F acting thereon and a drag D acting thereon in the water current that forms around the rotational moment center becomes zero, wherein the rotational moment center is located on the casing, and wherein the meridian plane is a vertical plane including a rotational axis of the propellers.
