[0031] Example

[0032] An offshore floating vertical axis wind power generation hydrogen production ship, comprising:

[0033] A hydrogen production floating vessel 1, a cable is connected to the deck of the hydrogen production floating vessel 1, and one end of the cable away from the hydrogen production floating vessel 1 is fixed to a seabed pile foundation;

[0034] The vertical axis wind power generation device 3 is distributed in an array on the top surface of the hydrogen production floating ship 1. The vertical axis wind power generation device 3 includes a bracket 9, a support shaft 14, a rotating drum 13, blades 4 and an air guide ring for guiding wind energy to the blades 4. The bracket 9 is fixed to the top surface of the hydrogen production floating ship 1, the rotating drum 13 is rotatably sleeved on the outside of the supporting shaft 14, the blades 4 are distributed in an annular shape around the rotating drum 13, the air guide ring is arranged on the outside of the blades 4 and the bottom end is connected to the bracket 9, and the supporting shaft 14 is vertically fixed on the bracket 9;

[0035] The seawater electrolysis hydrogen production device 2 is located inside the hydrogen production floating vessel 1. The seawater electrolysis hydrogen production device 2 is used to utilize the electric energy output by the vertical axis wind power generation device 3 to electrolyze the seawater;

[0036] The gas storage device is located inside the hydrogen production floating vessel 1 and is used to store hydrogen and oxygen produced by the seawater electrolysis hydrogen production device 2 .

[0037] In this embodiment, Figure 1 and Figure 2As shown, the cables connected to the deck of the hydrogen production floating ship 1 are used to stabilize the hull to prevent it from swaying excessively or drifting away in strong winds and waves. The array distribution of the vertical axis wind power generation device 3 can maximize the use of wind resources and improve power generation efficiency. The design of the wind guide ring helps to guide the wind direction so that the blades 4 can capture wind energy more effectively. The support shaft 14 and the bracket 9 should be designed to be a structure that can withstand strong wind loads to ensure the safety of the wind power generation device in severe sea conditions. The wind energy drives the blades 4 to rotate and then drives the drum 13 to rotate. The rotor of the corresponding generator (not shown in the figure) connected to the drum 13 starts to move to generate current, such as Figure 4 and Figure 5 As shown, the vertical axis wind power generation device 3 has a wind guide ring, which can guide the wind energy to the blades 4 to the greatest extent, improve the utilization rate of wind energy, and further improve the power generation efficiency of the vertical axis wind power generation device 3. The power generation device is composed of blades 4, wind guide rings, brackets 9, and support shafts 14. The entire vertical axis wind power generation device 3 has a simple structure, is easy to install, has low cost, and is easy to promote and apply. The seawater electrolysis hydrogen production device 2 (belonging to the existing public technology) uses the electric energy output by the vertical axis wind power generation device 3 to electrolyze seawater to produce hydrogen, and the generated hydrogen and oxygen are respectively stored in the gas storage device, which effectively solves the problem of electric energy required for offshore seawater electrolysis hydrogen production and has strong practicality.

[0038] It should also be noted that the reason for installing the vertical axis wind power generation device 3 on the hydrogen production floating ship 1 in this scheme is: if a conventional horizontal axis wind turbine is used, its blade rotation axis is parallel to the ground, and its center of gravity will change when the blade rotates, which will easily cause the center of gravity of the ship to change. The blade rotation axis of the vertical axis wind turbine is perpendicular to the ground, and the center of gravity is not easy to change when the blade rotates, and the center of gravity of the ship is also not easy to change, making the ship more stable.

[0039] Furthermore, a power storage device 16 and a rectifier 15 are provided on the circuit connecting the output end of the vertical axis wind power generation device 3 and the seawater electrolysis hydrogen production device 2. The rectifier 15 is located at the front end of the power storage device 16, and a cable is connected between the power storage device 16 and the rectifier 15.

[0040] Specifically, Figure 3As shown, the main function of the power storage device 16 is to store the electric energy generated by the vertical axis wind power generation device 3 so that it can be used when the wind is insufficient or continuous power supply is required to the electrolysis of seawater hydrogen production device 2. Taking into account the particularity of the marine environment, the power storage device 16 should use a battery that is resistant to seawater corrosion, high temperature and long-life, such as a lithium battery or an all-vanadium liquid flow battery. The power storage device 16 should be designed with charging management and discharge protection functions to ensure the safety and stable operation of the battery. The rectifier device 15 is located at the front end of the power storage device 16. Its main function is to convert the alternating current generated by the wind power generation device into direct current so as to supply the electrolysis of seawater hydrogen production device 2. Selecting an efficient and stable rectifier device 15 can improve the conversion efficiency of electric energy and reduce energy consumption. In general, this setting is quite reasonable and effective for an offshore floating vertical axis wind power generation hydrogen production ship, and can ensure the stable operation of the system and efficient energy conversion.

[0041] Furthermore, the power storage device 16 is a battery, and the rectifying device 15 is a rectifier.

[0042] Specifically, the battery as a power storage device 16 is mainly used to store the electric energy generated by the vertical axis wind power generation device 3. When the wind resources are abundant, the battery can store excess electric energy; when the wind is insufficient or continuous power supply is required to the electrolysis of seawater hydrogen production device 2, the battery can release the stored electric energy. The main function of the rectifier is to convert the alternating current generated by the wind power generation device into direct current so as to supply the electrolysis of seawater hydrogen production device 2. The rectifier realizes the conversion of alternating current to direct current by controlling the flow direction of the current. In the vertical axis wind power generation hydrogen production ship floating at sea, it is a reasonable choice to use a battery as a power storage device 16 and a rectifier as a rectifier device 15. Through reasonable design and selection, the stable operation of the system and efficient energy conversion can be ensured.

[0043] Furthermore, the gas storage device includes a hydrogen storage tank 18 and an oxygen storage tank 17, which are installed inside the hydrogen production floating vessel 1, and the hydrogen storage tank 18 and the oxygen storage tank 17 are connected to the gas outlet of the seawater electrolysis hydrogen production device 2 through pipelines.

[0044] Specifically, Figure 3As shown, the hydrogen storage tank 18 is used to store the hydrogen produced by the electrolysis of seawater hydrogen production device 2. Since hydrogen is a flammable and explosive gas, the hydrogen storage tank 18 needs to use special materials and designs to ensure its safety and reliability. The oxygen storage tank 17 is used to store the oxygen produced by the electrolysis of seawater hydrogen production device 2. Compared with hydrogen, oxygen is more stable, but appropriate measures are also needed to ensure storage safety. The hydrogen storage tank 18 and the oxygen storage tank 17 should be made of corrosion-resistant, high-pressure-resistant and high-temperature-resistant materials to meet the special requirements of the marine environment. The hydrogen storage tank 18 can be equipped with safety devices such as pressure sensors, temperature sensors and automatic discharge valves to prevent hydrogen leakage and explosion accidents. The oxygen storage tank 17 also needs to have similar safety devices to ensure storage safety. The capacity of the hydrogen storage tank 18 and the oxygen storage tank 17 should be reasonably planned according to the output of the electrolysis of seawater hydrogen production device 2 and the needs of offshore operations to ensure sufficient storage capacity and continuous supply capacity. The hydrogen storage tank 18 and the oxygen storage tank 17 are installed inside the hydrogen production floating ship 1 to protect them from the influence of sea waves and bad weather. At the same time, the installation location should take into account the need for convenient maintenance and overhaul. The hydrogen storage tank 18 and the oxygen storage tank 17 are connected to the gas outlet of the electrolytic seawater hydrogen production device 2 through pipelines. These pipelines need to be made of corrosion-resistant and high-pressure resistant materials to ensure the safe transportation of hydrogen and oxygen. At the same time, the connection of the pipelines should be firm and reliable to prevent leakage accidents.

[0045] Furthermore, a booster pump 19 is provided on the front end pipelines of the hydrogen storage tank 18 and the oxygen storage tank 17 .

[0046] Specifically, Figure 3 As shown, the booster pump 19 can increase the pressure of hydrogen and oxygen in the pipeline to meet the storage requirements of the hydrogen storage tank 18 and the oxygen storage tank 17. By adjusting the output of the booster pump 19, the flow rate of hydrogen and oxygen can be controlled to ensure a stable and safe storage process. During the transportation of hydrogen and oxygen, due to factors such as pipeline length, bending and friction, the pressure will be lost. The booster pump 19 can compensate for these losses to ensure that the gas enters the storage tank smoothly. Since hydrogen and oxygen have special chemical properties, the booster pump 19 should be made of corrosion-resistant materials to ensure its long-term stable operation. The booster pump 19 should have efficient and stable performance to ensure that it can continue to provide stable pressure output during continuous work.

[0047] Furthermore, the cross-section of the blade 4 is arc-shaped, and the concave surface of the blade 4 is the air suction surface. The air suction surface and the wind energy introduced by the air guide ring rotate counterclockwise to match. One long side of the blade 4 is connected to the outer wall of the rotating drum 13, and the other long side is connected to the connecting ring 7 on the outside of the blade 4. The connecting ring 7 is located between the blade 4 and the air guide ring.

[0048] Specifically, Figure 4As shown, the blade 4 adopts an arc-shaped structure. The arc-shaped blade 4 has a concave surface and a convex surface. The concave surface is the wind suction surface, and the wind suction surface corresponds to the direction of wind energy introduced by the wind guide ring. In this way, the introduced wind energy can act on the wind suction surface of the blade 4 to the greatest extent, thereby improving the utilization rate of wind energy, making the rotation speed of the blade 4 higher and the power generation efficiency higher.

[0049] In order to further improve the power generation efficiency of the blade 4, one long side of the blade 4 is fixedly connected to the side wall of the drum 13, and the other long side is connected to the connecting ring 7. In this way, the connecting ring 7 can avoid deformation of the blade 4 and further connect the blades 4 into a whole, thereby improving the rotation efficiency of the drum 13 and further improving the power generation efficiency.

[0050] Furthermore, the air guide ring includes an air guide plate 12 and a fixed ring 5. There are multiple fixed rings 5 ​​distributed from top to bottom. There are several air guide plates 12 distributed in a ring shape between two adjacent fixed rings 5. The air guide plates 12 are arranged obliquely, and an air guide channel 8 is formed between any two adjacent air guide plates 12 in the same circumferential direction.

[0051] Furthermore, a fixing piece is provided on the top surface of the upper fixing ring 5 , and the middle part of the fixing piece is connected to the upper end of the supporting shaft 14 .

[0052] Furthermore, the fixing member is integrally formed by three fixing rods 6 , which are distributed in a scattered manner, with an angle of 120° between two adjacent fixing rods 6 , and the outer ends of the fixing rods 6 are connected to the air guide plate 12 .

[0053] Specifically, Figure 4 As shown, there are three fixing rings 5, and there are several wind guide plates 12. The wind guide plates 12 are distributed in a ring shape between two adjacent fixing rings 5. A wind guide channel 8 is formed between any two adjacent wind guide plates 12 to guide wind energy to the blades 4. The wind guide plates 12 are inclined, that is, the angle between the lower end or the upper end of the wind guide plate 12 and the edge of the fixing ring 5 is an acute angle. In this way, the wind guide channel 8 formed between the two wind guide plates 12 is more matched with the direction of the airflow generated by the driving of the car, and the wind guiding effect is better. The blades 4 can feel more wind energy and the power generation efficiency is higher. The fixing part is formed by three fixing rods 6 in one piece. The intersection of the three fixing rods 6 is connected to the support shaft 14. The three fixing rods 6 form a triangular structure, which makes the support shaft 14 more stable. The outer end of the fixing rod 6 is fixedly connected to the top wind guide plate 12. The bracket 9 is composed of three support legs 11. The three support legs 11 form a triangular support with higher stability. The X-shaped reinforcing rod 10 can improve the bearing capacity and stability of the bracket 9.

[0054] The above is only a preferred embodiment of the utility model and does not limit the utility model in any form. According to the technical essence of the utility model, within the spirit and principles of the utility model, any simple modification, equivalent replacement and improvement made to the above embodiment still falls within the protection scope of the technical solution of the utility model.
