The protection mechanism is arranged outside the storage tank, and the inner side surface of the protection mechanism is fixedly connected to the outer surface of the storage tank, and the protection mechanism is fixedly connected to the top of the bottom plate; Wherein, the storage mechanism comprises: An oil bin, the oil bin is arranged inside the storage tank, and a transparent window is provided on one side of the oil bin close to the center of the storage tank, and the outer side of the oil bin is fixedly connected to the inner side of the storage tank; An oil inlet pipe, the oil inlet pipe is arranged on a side of the storage tank away from the bottom plate, an end of the oil inlet pipe close to the storage tank passes through the storage tank and extends to the inside of the oil bin, and the outer side surface of the oil inlet pipe is fixedly connected to the inner side surface of the storage tank, and the outer side surface of the oil inlet pipe is fixedly connected to the inner side surface of the oil bin; A material discharge assembly, which is arranged outside the storage tank and fixedly connected to the top of the bottom plate; A liquid level component, wherein the liquid level component has an observation structure for observing the liquid level inside the oil tank, the liquid level component is arranged inside the oil tank, and the outer side surface of the liquid level component is fixedly connected to the inner side surface of the storage tank; The tank emptying cabinet is placed on the deck of the ship and fixed on the deck through the threaded holes at the four corners of the bottom plate. Then, oil is injected into the oil tank through the oil inlet pipe to add or supplement the oil. When storing the oil, the oil inlet pipe is arranged on the top of the oil tank.

[0012] Furthermore, an elliptical hole is provided on one side of the first fixing ring close to the bottom plate, and the elliptical hole penetrates the first fixing ring and several second fixing rings at one time, and the first fixing ring and the second fixing ring are both made of elastic material, and there are several elliptical holes, and the several elliptical holes are evenly arranged along the circumference of the first fixing ring. When the ship shakes, the storage tank continues to move due to inertia, and the storage tank squeezes the first fixing ring and the second fixing ring, thereby providing buffering.

The oil hits the baffle, which is corrugated and made of flexible material. The baffle stretches after the impact, which can further buffer the oil. The circular hole connects the oil on both sides of the baffle to ensure sufficient discharge of the oil, so that the oil passes slowly to a certain extent, which can not only reduce the amplitude of the liquid shaking, but also balance the pressure of the liquid on both sides of the baffle to a certain extent, so that the baffle is more evenly stressed.
