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.

Abstract: A recovery system for large-scale spilled oil flowing onto and adhered to a shore is disclosed. The recovery system for large-scale oil flowing onto and adhered to a shore is mounted on an amphibious vehicle that can move on a neritic zone and land. A skimmer assembly is installed in a front of the amphibious vehicle. An oil collection assembly is foldably provided on each of front opposite sides of the amphibious vehicle, thereby easily collecting oil. A recovered oil treatment assembly is mounted on the amphibious vehicle and configured to accommodate the oil recovered by the skimmer assembly therein and to store separated oil by separating water from the accommodated oil.

Abstract: The present invention relates to a hydraulic height adjusting device for installing a heavy-weight structure to secure stable horizontal bearing power against a horizontal load of a heavy-weight upper structure. The present invention includes a lower frame which is installed on a top surface of the carrier and is provided with a plurality of receiving portions formed in an upwardly opened shape; and a hydraulic cylinder which is disposed in and engaged to the respective receiving portions of the lower frame, the hydraulic cylinder being moved in a vertical direction to adjust the height of the upper structure, in a state in which an upper end thereof supports the upper structure. The receiving portion is provided with a support guide which is interposed between an inner wall of the receiving portion and the hydraulic cylinder to annually enclose the hydraulic cylinder and thus prevent the hydraulic cylinder from being tilted.

Abstract: According to the present disclosure, at least two fluid inlet/outlet pipes, each of which is provided with a filter, are installed outside a structure to be bent and an end of each of the fluid inlet/outlet pipes is connected to a pressure sensor provided on the structure. Thus, since a fluid in the state in which low-frequency and high-frequency components of the disturbances generated outside the structure are removed therefrom acts on the pressure sensor, the underwater pressure sensing apparatus is capable of measuring fluid pressure in a stable state.
