The ships are all provided with a liquid cargo tank, namely a closed tank used for carrying liquid cargo. When the cargo tank is loaded with liquid cargo, the cargo tank cannot be completely filled based on the amount of cargo and the safety of the liquid cargo, so that a space often remains above the liquid cargo level in the cargo tank.
Due to the reason, free liquid level exists in the liquid cargo tank, namely when the ship swings in the sailing process, liquid cargo in the liquid cargo tank flows along with the swing of the ship, and then the center of gravity of the whole liquid cargo in the liquid cargo tank deviates, so that an extra tilting moment is generated, the swing amplitude of the ship is increased, and the stability of the ship is further influenced.
In the process of the rolling motion of the ship, the rolling motion of the ship is severe, in order to reduce the influence of the free liquid level, a longitudinal bulkhead is usually added in a liquid cargo tank, 1 or 2 longitudinal bulkheads are used for horizontally dividing the liquid cargo tank into 2 or 3 longitudinal liquid cargo tanks, the offset distance in the liquid cargo offset process is reduced in this way, and further the influence of the free liquid level on the stability of the ship is reduced, but even if the longitudinal bulkheads are added, the liquid cargo tank has large size, so when the liquid cargo tank is inclined under the action of wind waves in the sailing process of the liquid cargo ship, the liquid cargo still has large inclination moment (within the allowable range of the liquid cargo ship), which cannot be avoided.
When the ship rolls, the liquid cargo in the liquid cargo tank can move along with the rolling of the ship, so that the liquid cargo has certain mechanical energy, particularly, the rolling motion of the ship is particularly severe in a heavy storm day, and the mechanical energy contained in the liquid cargo is particularly abundant.

As shown in fig. 16, when the ship leans to the left during the sailing process, the liquid cargo level in the cargo tank will flow toward the left bulkhead (the bulkhead close to the port side in the cargo tank), which causes the liquid cargo level at the right side in the cargo tank to lower relative to the right bulkhead (the bulkhead close to the right side in the cargo tank), the liquid cargo level at the left side in the cargo tank to raise relative to the left bulkhead (the bulkhead close to the port side in the cargo tank), the volume of the right floating plate 7 immersed in the liquid cargo level decreases, the buoyancy of the right floating plate 7 in the liquid cargo decreases, the buoyancy of the left floating plate 6 in the liquid cargo does not change, the right floating plate 7 will move toward the bottom of the cargo compartment along the right guide bar 5 under the action of its own weight, therefore, the rope belt 8 is pulled to move, the rope belt 8 can provide certain pulling force for the left floating plate 6, and the left floating plate 6 can move towards the cabin top along the left guide rod 4 under the action of the pulling force of the rope belt 8. In the moving process of the left floating plate 6 and the right floating plate 7, the rope belt 8 drives the belt wheel 901 to rotate, so that the generator 902 generates electricity. In fact, the vessel's heeling and heeling are often continuously alternated, so the device of the present invention is able to generate electricity continuously during the rolling motion of the vessel.
Furthermore, the invention is preferably used for liquid cargo ships (oil tankers, liquefied gas ships, liquid chemical ships and the like), the liquid cargo ships generally have large load capacity, the number of liquid cargo tanks on the ships is large, the size of each liquid cargo tank is large, one to two groups of the device can be arranged in each liquid cargo tank, so that the device can be arranged on the whole ship in a large number, and when the liquid cargo ships are subjected to wind wave action to swing in the sailing process, the recoverable energy is very large, and the power generation effect is good.
