When the second spring 12 is in a natural state, the second floating plate 17 is in contact with the second piezoelectric ceramic 18.

[0080] When the sea surface fluctuates, the second body 14 vibrates, the second floating plate 17 moves up and down under the action of the vibration of the second body 14, and the ship exhaust in the first air cushion 2 is sucked into the second body 14 / the ship exhaust in the second body 14 is sent to the carbon dioxide inlet 301; the second piezoelectric ceramic 18 can be compressed when the second floating plate 17 moves up.

[0087] In the embodiment, further comprising:

[0088] The LED lamp 23 is made of transparent glass, so that the seaweed can carry out sufficient photosynthesis during the day and avoid impurities entering the seaweed cultivation box 3, the LED lamp 23 is arranged in the seaweed cultivation box 3 and is electrically connected with the first piezoelectric ceramic 10 and the second piezoelectric ceramic 18;

[0089] The zirconium oxide oxygen content analyzer is arranged in the seaweed cultivation box 3, and the seaweed cultivation box 3 communicates with the gas storage tank through the oxygen outlet, and a safety valve is arranged on the oxygen outlet.

[0090] In the embodiment, further comprising:

[0091] The outer shell 27 is made of transparent material and is rotatably installed inside the seaweed cultivation box 3. The LED light 23 is installed inside the outer shell 27. The outer surface of the outer shell 27 is provided with guide vanes 28. When the ship's exhaust gas enters the seaweed cultivation box 3 through the carbon dioxide inlet 301, it can drive the outer shell 27 and the guide vanes 28 to rotate.

[0092] In this embodiment, it also includes:

[0093] The second air cushion 24 is placed on top of the seaweed cultivation box 3;

[0094] The first valve is located at the first air inlet 201;

[0095] The second valve is located at the second air inlet 601;

[0096] The third valve is located at the carbon dioxide inlet 301;

[0097] The vent 25 is connected to the second high-pressure tank 19. The vent 25 is equipped with a vent valve, which is a one-way valve that only allows gas to be discharged to the outside of the second high-pressure tank 19. The vent 25 is lower than the carbon dioxide inlet 301.

[0098] The seaweed cultivation box 3 has a seawater exchange port, which is equipped with a water exchange valve.

[0099] The specific work process is as follows:

[0100] Under normal conditions, the first, second, and third valves are all open, the vent valve is closed, and the ship's exhaust gas enters the gas supply pipe 1. When it flows through the cooling device, the ship's exhaust gas exchanges heat with the seawater in the cooling chamber and cools down. The seawater absorbs heat and evaporates, entering the collection section 5 through the vent. The temperature of the ship's exhaust gas drops to a temperature suitable for seaweed absorption.

[0101] Driven by wave energy, the first body 6 and the second body 14 vibrate synchronously. In the first body 6, when the first float 9 moves downward, ship exhaust gas from the gas supply pipe 1 enters the first body 6. When the first float 9 moves upward, the space within the first body 6 is compressed, and ship exhaust gas is sent from the first body 6 into the first high-pressure tank 11, which in turn lifts the first sphere 13 and sends it into the first air cushion 2 through the first air inlet 201. Simultaneously, the first float 9 compresses the first piezoelectric ceramic 10 to generate electricity, which powers the LED light 23, providing the light energy needed for photosynthesis in the seaweed. The operating mechanism of the second body 14 is the same as that of the first body 6, except that the first body 6 is used to send ship exhaust gas from the gas supply pipe 1 into the first air cushion 2, while the second body 14 is used to transport ship exhaust gas from the first air cushion 2 to the carbon dioxide inlet 301 of the seaweed cultivation tank 3.

[0102] The first body 6 and the second body 14 are connected by the rigid lever 22, so that the first body 6 and the second body 14 vibrate synchronously, thereby realizing synchronous suction and synchronous exhaust, and the gas flow of the two is the same. Under the action of the first body 6 and the second body 14, the ship exhaust is periodically discharged into the seaweed cultivation box 3, is absorbed and treated by seaweed, and the first air cushion 2 maintains the dynamic balance of the internal air pressure and provides stable support force for the seaweed cultivation box 3. The LED lamp 23 periodically emits light under the action of the first piezoelectric ceramic 10 and the second piezoelectric ceramic 18, and irradiates the seaweed with the effect of “flickering”. The seaweed performs photosynthesis in the alternating light and dark environment. Research shows that the light and dark alternating environment can significantly improve the photosynthetic carbon fixation efficiency of seaweed, that is, improve the processing efficiency of seaweed on ship exhaust carbon dioxide.

[0103] When the ship exhaust enters the seaweed cultivation box 3 through the carbon dioxide inlet 301, the ship exhaust has a certain air pressure and can drive the shell 27 and the guide vane 28 to rotate. The seaweed in the seaweed cultivation box 3 is planted in a suspended manner in water, so the guide vane 28 can drive the seaweed to rotate, play a stirring role, and make the seaweed more fully absorb carbon dioxide in the ship exhaust, thereby improving the processing effect and efficiency of carbon dioxide.

[0104] The oxygen content in the seaweed cultivation box 3 is detected and compared by the zirconium oxide oxygen content analyzer. When the oxygen in the seaweed cultivation box 3 reaches a preset value, the safety valve is opened, the oxygen is collected into the gas storage tank, and the safety valve is automatically closed after a period of discharge.

[0105] When the seaweed cultivation box 3 needs to be replaced with water, the first valve and the third valve are closed, the second valve and the air release valve are opened, and the ship exhaust in the first air cushion 2 is discharged from the air release port 25 and is not supplemented (the air release valve is a one-way valve). After the first air cushion 2 is discharged, the support force of the seaweed cultivation box 3 is insufficient, and the seaweed cultivation box 3 and the first air cushion 2 sink below the sea surface together. At this time, the second air cushion 24 floats on the sea surface, and the seaweed cultivation box 3 is pulled up by the buoyancy of the second air cushion 24 to avoid further sinking of the device as a whole. The seawater in the seaweed cultivation box 3 is replaced with external seawater by opening the water replacement valve. After the seawater is fully replaced, the water replacement valve is closed.

[0106] The air release valve and the second valve are closed, and the first valve is opened. Under the action of the wave energy air inlet device, the first air cushion 2 is quickly inflated. When the gas pressure sensor detects that the first air cushion 2 reaches a preset air pressure, the second valve and the third valve are opened, the air pressure dynamic balance of the first air cushion 2 is restored, the first air cushion 2 generates buoyancy, and the first air cushion 2 and the seaweed cultivation box 3 rise to the sea surface together, and the device starts to work again.
