Abstract

This application relates to a multifunctional recovery apparatus of shore adhesion oils. The multifunctional recovery apparatus of shore adhesion oils removing and recovering oil spilling and sticking at a shore is mounted on a four-wheel vehicle. A skimmer assembly separating oil sticking to the surface of rocks at a shore, and absorbing and recovering an oil spill at the shore is installed at the front of the four-wheel vehicle. The skimmer assembly includes a rotary skimmer having a rotary roller separating oil, and a vacuum suction skimmer suctioning oil floating on a water surface. The rotary skimmer and the vacuum suction skimmer may be selectively or simultaneously used, if necessary.

First claim

What is claimed is:

1. A multifunctional recovery apparatus of shore adhesion oils that is mounted on a four-wheel vehicle and removes and recovers oil flowing to a shore or oil stuck to the shore, the multifunctional recovery apparatus comprising:
a skimmer assembly installed at the front of the four-wheel vehicle, separating oil sticking to a surface of sand or gravel at a shore, and absorbing and recovering oil flowing to the shore; and
an oil storage tank selectively receiving oil recovered from the skimmer assembly,
wherein the skimmer assembly comprises:
a rotary skimmer separating and collecting oil sticking to a surface of sand or gravel at a shore; and
a vacuum suction skimmer disposed behind the rotary skimmer and adsorbing oil flowing on a water surface,
wherein the rotary skimmer comprises:
a skimmer body configured to separate oil;
a scraper protruding toward the skimmer body to separate oil and foreign substances from the skimmer body;
a discharge pipe configured to discharge the oil and the foreign substances separated by the scraper to the outside; and
a transfer pump disposed under the scraper and transferring oil and water dropping from a lower portion of the scraper to the oil storage tank or to the outside,
and wherein an oil recovery bag for recovering the discharged oil and foreign substances is detachably coupled to an outlet of the discharge pipe.

2. The multifunctional recovery apparatus of claim 1 , wherein the transfer pump comprises:
a first transfer line having a first end connected to the transfer pump and a second end connected to the oil storage tank; and
a second transfer line having a first end connected to the transfer pump and a second end connected to an external discharge hose provided from the outside, and
a valve selectively opening and closing the second transfer line is disposed at the first end of the second transfer line.

3. The multifunctional recovery apparatus of claim 2 , wherein the skimmer body comprises:
a separator disposed to be able to horizontally rotate and having coupling protrusions at both ends, respectively;
a cover plate having both sides to which both ends of the separator are rotatably coupled, respectively, and shielding an upper portion of the separator;
a guide screw rotatably disposed inside the cover plate and transferring oil and foreign substances separated by the scraper to the discharge pipe; and
an oil storage container disposed under the scraper, receiving oil and water dropping from the lower portion of the scraper, and having the transfer pump therein.

4. The multifunctional recovery apparatus of claim 3 , wherein the separator comprises:
a rotary roller disposed to be able to rotate horizontally with respect to the ground; and
a brush spirally disposed on an outer surface of the rotary roller in a longitudinal direction,
wherein the brush is a bunch of fibers made of a lipophilic material.

5. The multifunctional recovery apparatus of claim 3 , wherein the separator comprises a rotary drum disposed to be able to rotate horizontally with respect to the ground, and a surface of the rotary drum has lipophilicity.

6. The multifunctional recovery apparatus of claim 3 , wherein the skimmer assembly further comprises a vacuum tank connected to the vacuum suction skimmer and transmitting vacuum suction force to the vacuum suction skimmer.

7. The multifunctional recovery apparatus of claim 6 , further comprising an up-down actuator having a first side connected to the vacuum suction skimmer and a second side connected to the four-wheel vehicle, and moving up and down the vacuum suction skimmer.

8. The multifunctional recovery apparatus of claim 3 , further comprising connection arms disposed in parallel with each other at the front of the four-wheel vehicle, each having a first side hinged to the front of the four-wheel vehicle and a second side connected to the cover plate.

9. The multifunctional recovery apparatus of claim 8 , wherein a tongs-shaped gripper is disposed at the second ends of the connection arms, so the rotary skimmer is separably coupled.

10. The multifunctional recovery apparatus of claim 9 , wherein a disc-type oil recoverer is separably coupled to the grippers.

11. The multifunctional recovery apparatus of claim 10 , wherein the disc-type oil recoverer comprises:
a frame body forming an external shape and a frame;
a rotary shaft rotatably installed on the frame body;
a drum composed of a plurality of discs arranged on the rotary shaft with regular intervals in a longitudinal direction of the rotary shaft; and
a drum skimmer protruding from the frame body facing the drum and separating oil and foreign substances from a surface of the drum.

12. The multifunctional recovery apparatus of claim 11 , wherein the frame body is made of fiber reinforced plastics (FRP).
