Portable oil skimmer

A portable oil skimmer comprising:

• a collection unit configured to collect spilled oil while floating on an ocean surface,
• wherein the collection unit comprises:
• a main body configured to allow a first oil-skimming member to be rotatably mounted on a front end thereof, a second oil-skimming member to be rotatably mounted on a rear end thereof, and a pipe to be connected to an upper portion thereof so as to communicate with an interior thereof,
• a pair of buoyant bodies mounted on two side surfaces of the main body, with the main body interposed therebetween;
• an oil pump disposed in the main body, the oil pump being configured to convey oil collected by the first oil-skimming member and the second oil-skimming member outside of the main body through the pipe;
• a first motor configured to generate rotational driving force to be supplied to the first oil-skimming member;
• a first battery configured to supply power to the first motor;
• a first power transmission unit configured to transmit rotational driving force generated by the first motor to the first oil-skimming member,
• wherein the pair of buoyant bodies comprises a first buoyant body mounted on a left surface of the main body:
• wherein the first motor, the first battery, and the first power transmission unit are disposed in a first space defined in the first buoyant body,
• wherein the first buoyant body comprises:
• a plurality of protruding portions protruding from an inner side surface thereof toward the first space;
• a lower portion defining the first space having an open upper side;
• and
• an upper portion coupled to the lower portion to cover the open upper side of the first space, and
• wherein the protruding portions protrude in a direction from grooves formed in the lower portion for coupling to the upper portion toward the first space.
