[0019] In this embodiment, when in use, the oil supply unit is installed on the first support frame and the second support frame through a bolt assembly, and then the semi-elliptical shell cover 2 is buckled on the base frame 1, at this time, the first opening 4 of the semi-elliptical shell cover 2 is in contact with the base frame 1, and then the semi-elliptical shell cover 2 is locked with the base frame 1 through the lock, so that the damage of the oil supply unit caused by collision can be prevented. Meanwhile, when being transported, the oil supply unit is first installed on the first support frame and the second support frame through a bolt assembly, and then the free end of the lifting rope is extended into the semi-elliptical shell cover 2 from outside the semi-elliptical shell cover 2 through the second opening 3 to fix the first support frame and the second support frame, and then the semi-elliptical shell cover 2 is buckled on the base frame 1, and finally the semi-elliptical shell cover 2 is locked with the base frame 1 through the lock, so that lifting can be realized and the oil supply unit can be protected, and the force applied by the lifting rope is applied at the center of gravity of the whole composed of the oil supply unit, the base frame and the semi-elliptical shell cover 2 (the main weight is the oil supply unit), so that the oil supply unit, the base frame and the semi-elliptical shell cover 2 can be prevented from being tilted during lifting. The design that the projections of the first support frame and the second support frame on the upper surface of the base frame 1 are located in the upper surface of the base frame 1 makes it convenient to cover the semi-elliptical shell cover 2 on the base frame 1, and meanwhile, the edge of the base frame 1 beyond the semi-elliptical shell cover 2 also has a protective effect on the oil supply unit and the semi-elliptical shell cover 2, which makes a distance between the semi-elliptical shell cover 2 and objects outside the semi-elliptical shell cover 2.

[0020] As a preferred mode, the base frame 1 and the first support frame and the second support frame are all made of carbon steel. Carbon steel is easy to weld, convenient to process and low in price, thereby saving cost.

In this way, the first top plate 6 and the second top plate 8 play a supporting role for the oil supply unit, and the gap between the two adjacent first support columns 5 and the gap between the two adjacent second support columns 7 facilitate the hoisting rope to pass through, so that the free end of the hoisting rope can be tied to the first support frame and the second support frame.

[0022] As a preferred mode, the lock includes a 7-shaped plate 9, a first screw hole 10, a second screw hole 11, a bolt 12, the vertical part of each 7-shaped plate 9 is fixedly connected with the upper surface of the base frame 1 at the end away from the transverse part, the free end of the transverse part of each 7-shaped plate 9 faces away from the whole composed of the first support frame and the second support frame, the first screw hole 10 is arranged on the transverse part of each 7-shaped plate 9, the connecting plate 13 is arranged on the semi-elliptical shell cover 2, the second screw hole 11 is arranged on the connecting plate 13, and the bolt 12 is arranged to pass through the first screw hole 10 and the second screw hole 11 to lock the semi-elliptical shell cover 2 and the base frame 1 together. After the arrangement, the bolt 12 is arranged to pass through the first screw hole 10 and the second screw hole 11 to lock the semi-elliptical shell cover 2 and the base frame 1 together. The 7-shaped plate 9 is arranged to facilitate the installation of the bolt 12 when the lower surface of the base frame 1 is in contact with the ground (as shown in Figure 1 Figure 2 ).

[0023] As a preferred mode, the connecting plate 13 is arranged on the outer circumferential surface of the semi-elliptical shell cover 2 at the first opening 4. The semi-elliptical shell cover 2 is fixedly connected with the 7-shaped plate 9 through the connecting plate 13. After the arrangement of the connecting plate 13, a distance is arranged between the connecting plate 13 and the edge of the first opening 4 of the semi-elliptical shell cover 2, and the distance is equal to the length of the vertical part of the 7-shaped plate 9, so that when the semi-elliptical shell cover 2 is closed on the base frame 1, the bolt 12 is arranged to fixedly connect the connecting plate 13 and the 7-shaped plate 9 together.

[0024] As a preferred mode, the semi-elliptical shell cover 2 is made of carbon steel.

[0025] As a preferred mode, the lower surface of the base frame 1 is provided with an anti-skid rubber layer 14. The anti-skid rubber layer 14 prevents the base frame 1 from sliding when placed on the deck of a ship.
