Description

Technical Field

[0001] The invention belongs to the technical field of offshore wind power generation and relates to an offshore wind power generation ship. Background Art

[0002] In recent years, the offshore wind power industry has prospered. According to Clarkson's forecast, the scale of offshore wind power operation is expected to grow at an average annual compound growth rate of 23%, increasing to more than 250GW by the beginning of 2030. With the continuous expansion and operation of offshore wind farms, the demand for operation and maintenance ships is also increasing.

[0003] At present, offshore wind power has a higher technical threshold than onshore wind power. The technology for accepting large-capacity wind power has not yet been broken through, and the contradiction of benefit sharing with conventional power sources has not been resolved. This makes it difficult for offshore wind power to be stably connected to the power grid, which in turn affects its large-scale development. The construction and operation and maintenance of offshore wind farms need to face complex environmental conditions, such as typhoons and waves. This increases the difficulty and cost of construction and operation and maintenance; at the same time, the performance of offshore wind power installation ships and operation and maintenance ships also needs to be continuously improved to meet the needs of large-scale and far-reaching offshore wind power projects.

[0004] The operation and maintenance costs of offshore wind farms are relatively high, mainly including the costs of ship operation and maintenance, equipment maintenance, personnel training, etc. At present, some equipment still has deficiencies in reliability and needs to be further improved. Common offshore wind power generation equipment and offshore operation and maintenance ships operate separately. This means that when the hull is operating at sea, facing sudden changes in the environment, the offshore wind power generation equipment sometimes cannot supply power to the hull in time. If the power cannot be replenished in time, it will bring certain safety hazards to the normal operation of the hull. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that offshore wind power generation equipment and offshore operation and maintenance ships are operated separately in the prior art, which means that when the hull is operating at sea, it is faced with sudden changes in the environment and sometimes cannot replenish electricity in time. If electricity cannot be replenished in time, it will bring certain safety hazards to the normal operation of the hull. How to combine offshore wind power generation and the operation of the hull in the most convenient way is a problem to be considered at present. Based on this, an offshore wind power generation ship is provided, which simplifies the energy transmission process, reduces energy loss, and makes the entire system more compact and efficient, providing reliable guarantee for the autonomous navigation and power supply of the ship, so that the hull can flexibly face various situations at sea, and improves the utilization efficiency of offshore wind power.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] An offshore wind power generation ship comprises a hull, wherein a plurality of cross beams are arranged on both sides of the hull, vertical rods are arranged on the cross beams, blades are arranged on the vertical rods, and the blades are connected to power generation units;

[0008] The power generation unit is connected to the hull driving unit.

[0009] Furthermore, in the present invention, the cross beams are vertically distributed along the hull.

[0010] Furthermore, in the present invention, the cross beams on both sides of the hull are distributed in parallel in sequence.

[0011] Furthermore, the present invention also includes a float, which is arranged at the end of the beam away from the hull.

[0012] Furthermore, in the present invention, the floats on either side of the hull are all integrated structures, and the floats connect several beams on the corresponding side in sequence.

[0013] Furthermore, in the present invention, the float is made of polyethylene.

[0014] Furthermore, in the present invention, the crossbeam is fixedly connected to the hull.

[0015] Furthermore, in the present invention, the power generation unit is a generator motor, and the generator motor is rotationally connected to the blades.

[0016] Furthermore, in the present invention, the vertical rod is rigidly connected to the horizontal beam.

[0017] Furthermore, in the present invention, a plurality of the vertical rods are distributed at intervals along the cross beam.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The invention discloses an offshore wind power generation ship, which takes the hull as the base, and a plurality of beams and vertical rods are arranged on both sides of the hull, so that the layout of the blades is more flexible, and the angle or position can be adjusted according to the change of wind direction and wind speed, so as to maximize the capture efficiency of wind energy, enhance the adaptability and stability of the wind power generation ship under different sea conditions and climatic conditions, and the connection between the blades and the power generation unit can efficiently capture the abundant wind energy resources at sea and convert them into electric energy, and the power generation unit is directly connected to the hull drive unit, so as to realize the instant conversion and utilization of energy, and this integrated design not only simplifies the energy transmission process and reduces energy loss, but also makes the whole system more compact and efficient, and provides reliable guarantee for the autonomous navigation and power supply of the ship, so that the hull can flexibly face various situations at sea, and improve the utilization efficiency of offshore wind power, and the power generation method of the hull does not produce any harmful emissions during operation, and is friendly to the marine environment. In addition, by effectively utilizing wind energy, the fuel consumption and operating costs of the ship can be significantly reduced, and a win-win situation of economic benefits and environmental benefits can be achieved.

[0020] Furthermore, in the present invention, the cross beams are distributed vertically along the hull, so that the blades can be more evenly distributed on both sides of the hull, thereby more effectively capturing wind energy from different directions. This layout reduces the wind energy loss caused by changes in wind direction and improves the power generation efficiency of the entire system. The vertically distributed cross beams provide additional support and stability for the hull, dispersing the impact of wind and waves on the hull, thereby enhancing the stability and safety of the entire wind turbine.

[0021] Furthermore, in the present invention, the beams on both sides of the hull are distributed in parallel, and the parallel distribution of the beams forms a stable support frame on both sides of the hull. This layout can effectively disperse the various forces borne by the hull, such as wind force, wave impact, etc., thereby improving the structural stability of the entire wind turbine, and can ensure that the hull can still maintain stable operation in high wind speeds and huge waves. The parallel distribution of the beams also helps to reduce the efficiency loss caused by mutual interference between wind turbines.

[0022] Furthermore, the present invention also includes a float, which is arranged at the end of the beam away from the hull. The arrangement of the float significantly increases the buoyancy of the wind turbine when operating at sea, helps the hull to better adapt to fluctuations in sea conditions, and reduces the risk of shaking and capsizing caused by natural factors such as waves and tides. The float also helps to balance the buoyancy on both sides of the hull, improves the stability of the entire wind turbine, and ensures that it can still generate electricity stably in severe sea conditions. In the installation position, the float is installed at the end of the beam, which can directly bear part of the wind force, reduce the direct impact of wind force on the hull, and thus protect the hull from damage.

[0023] Furthermore, in the present invention, the floats on either side of the hull are all integrated structures, and the floats sequentially connect several beams on the corresponding side. In this solution, the integrated floats extend along the side of the hull, tightly connecting multiple beams together to form a stable side support system. This enhances the hull's ability to resist roll when encountering lateral external forces such as wind and waves, ensuring the stability of the wind turbine in severe sea conditions. At the same time, the continuity of the floats helps to reduce the swaying amplitude of the hull in the waves, allowing the wind turbine to operate more stably and reducing energy loss and equipment damage caused by shaking.

[0024] Furthermore, in the present invention, the float is made of polyethylene, which has extremely strong corrosion resistance and can resist the erosion of salt, chemicals and microorganisms in seawater, so that the float can maintain stable performance in long-term offshore operations, extend service life and reduce maintenance costs.

[0025] Furthermore, in the present invention, the fixed connection between the vertical rod and the hull provides a solid support structure for the entire wind turbine. This connection method helps to enhance the overall strength and rigidity of the hull, so that the hull can better resist the impact of natural forces such as wind and waves when operating at sea, and maintain the stability of the hull.

[0026] Furthermore, in the present invention, the power generation unit is a generator motor, and the generator motor is rotationally connected to the blades. The direct rotational connection between the generator motor and the blades reduces the loss of energy during the transmission process. The wind energy captured by the blades is directly transmitted to the generator motor through rotation, thereby converting it into electrical energy.

[0027] Furthermore, in the present invention, the vertical rods and the horizontal beams are rigidly connected, and a stable support frame is formed between the two, which significantly enhances the overall rigidity of the wind turbine. This stability helps to resist various external forces brought by the complex offshore environment, such as wind and wave impact, ship shaking, etc., to ensure the stable operation of the hull and power generation equipment.

[0028] Furthermore, in the present invention, the vertical rods are spaced along the cross beams, providing more options and flexibility for the installation of the wind turbine. According to the wind resources, the hull size and the power generation demand, the number and position of the vertical rods can be reasonably adjusted to optimize the layout of the wind turbine.

[0039] See also Figure 1 The embodiment of the present invention discloses an offshore wind power generation ship, which solves the problem that offshore wind power generation equipment and offshore operation and maintenance ships in the prior art are operated separately, which makes it sometimes impossible to replenish electricity in time when the hull is operating at sea and faces sudden changes in the environment. If the electricity cannot be replenished in time, it will bring certain safety hazards to the normal operation of the hull. The device arranges an array of wind turbines on the hull and on both sides of the ship to maximize the use of wind field power on the sea surface. On both sides of the hull, a number of fixed beams are installed, and supporting vertical rods and generators are installed on the beams. Fixed floats are installed at the ends of the beams, and their buoyancy plays a role in supporting the wind turbines. When the hull is moored or sailing, it generates electricity under the action of the sea breeze.

[0040] Specifically, it includes the following structures:

[0041] Example 1

[0042] The present embodiment discloses an offshore wind power generation ship, including a hull 1, wherein a plurality of cross beams 6 are arranged on both sides of the hull 1, vertical rods 4 are arranged on the cross beams 6, blades 3 are arranged on the vertical rods 4, and the blades 3 are connected to a power generation unit; the power generation unit is connected to a hull driving unit.

[0043] Furthermore, in an embodiment of the present invention, the power generation unit can be connected to the hull driving unit via a cable, and the electric energy generated by the power generation unit is transmitted to the driving unit on the hull via the cable. The electric energy can also be transmitted wirelessly, for example, the electric energy generated by the wind turbine can be transmitted to the hull via microwave transmission or laser transmission.

[0044] It should be noted that the present device is not limited to the above two disclosed methods of connecting the power generation unit and the hull drive unit, as long as the power generation unit can transmit the generated electrical energy to the hull drive unit to drive the hull.

[0045] Furthermore, in the embodiment of the present invention, the cross beam 6 can be flexibly arranged according to the size of the hull, and the cross beam 6 and the vertical pole 4 can adjust the angle or position according to the changes in wind direction and wind speed, so as to maximize the wind energy capture efficiency and enhance the adaptability and stability of the wind power ship under different sea conditions and climatic conditions.

[0046] Furthermore, in the embodiment of the present invention, the blades 3 are connected to the power generation unit to directly convert wind energy into electrical energy, and the wind power ship can efficiently capture the abundant wind energy resources at sea and convert them into electrical energy. This method of directly utilizing natural wind energy is not only environmentally friendly and pollution-free, but also helps to reduce dependence on fossil fuels and promote the development of sustainable energy.

[0047] This embodiment uses the hull as the base, and a number of beams and vertical rods are set on both sides of the hull, so that the layout of the blades is more flexible, and the angle or position can be adjusted according to the changes in wind direction and wind speed, so as to maximize the capture efficiency of wind energy, enhance the adaptability and stability of wind power generation ships under different sea conditions and climate conditions, and the connection between the blades and the power generation unit can efficiently capture the abundant wind energy resources at sea and convert them into electrical energy. At the same time, the power generation unit is directly connected to the hull drive unit, realizing the instant conversion and utilization of energy. This integrated design not only simplifies the energy transmission process and reduces energy loss, but also makes the entire system more compact and efficient, providing reliable guarantee for the autonomous navigation and power supply of the ship, so that the hull can flexibly face various situations at sea, improve the utilization efficiency of offshore wind power, and the power generation method of the hull does not produce any harmful emissions during operation, which is friendly to the marine environment. In addition, by effectively utilizing wind energy, the fuel consumption and operating costs of the ship can be significantly reduced, achieving a win-win situation of economic benefits and environmental benefits.

[0048] Example 2

[0049] The present embodiment discloses an offshore wind power generation vessel, comprising a hull 1, wherein a plurality of cross beams 6 are arranged on both sides of the hull 1, vertical rods 4 are arranged on the cross beams 6, blades 3 are arranged on the vertical rods 4, and the blades 3 are connected to a power generation unit; the power generation unit is connected to a hull driving unit, and the cross beams 6 are vertically distributed along the hull 1.

[0050] Furthermore, in the embodiment of the present invention, the vertical distribution design of the cross beam 6 enables the wind turbines to be more evenly distributed on both sides of the hull, thereby more effectively capturing wind energy from different directions. This layout reduces the loss of wind energy caused by changes in wind direction, improves the power generation efficiency of the entire system, and the vertically distributed cross beam 6 provides additional support and stability for the hull 1. When operating at sea, the hull will be affected by natural forces such as wind and waves and produce shaking and vibration. The vertical design of the cross beam 6 helps to disperse these forces and reduce the impact on the hull structure, thereby enhancing the stability and safety of the entire wind turbine.

[0051] Furthermore, in the embodiment of the present invention, by vertically arranging the cross beams 6 on both sides of the hull, the space above the hull can be more effectively utilized to install the wind turbine, and this layout not only reduces the occupation of the internal space of the hull, but also makes the installation and maintenance of the wind turbine more convenient. At the same time, sufficient space is reserved for possible future expansion and upgrading.

[0052] Furthermore, in the embodiment of the present invention, the vertically distributed cross beams 6 have little effect on the hydrodynamic performance of the hull, which helps to maintain the streamlined design of the hull and reduce the resistance during navigation. This can not only increase the navigation speed of the wind power ship, but also reduce fuel consumption.

[0053] Example 3

[0054] The present embodiment discloses an offshore wind power generation ship, including a hull 1, wherein a plurality of cross beams 6 are arranged on both sides of the hull 1, vertical rods 4 are arranged on the cross beams 6, blades 3 are arranged on the vertical rods 4, and the blades 3 are connected to a power generation unit; the power generation unit is connected to a hull driving unit, and the cross beams 6 on both sides of the hull 1 are distributed in parallel.

[0055] Furthermore, in the embodiment of the present invention, the parallel beams 6 form a stable support frame on both sides of the hull. This layout can effectively disperse various forces borne by the hull, such as wind force, wave impact, etc., thereby improving the structural stability of the entire wind turbine. This stability is particularly important for wind turbines operating in harsh sea conditions, and can ensure that they can still maintain stable operation in high wind speeds and huge waves.

[0056] Furthermore, in the embodiment of the present invention, the beams 6 are all distributed in parallel, providing an orderly and regular spatial layout for the installation of wind turbines. Specifically, in this embodiment, three parallel beams 6 are respectively arranged on both sides of the hull 1, and the number on both sides is the same, thereby ensuring the balance of the support on both sides of the hull.

[0059] Furthermore, in the embodiment of the present invention, the float 5 increases the buoyancy of the wind turbine when operating at sea, which helps the hull to better adapt to the fluctuations in sea conditions and reduces the risk of shaking and capsizing caused by natural factors such as waves and tides.

[0060] Furthermore, in the embodiment of the present invention, the specific connection method between the float 5 and the crossbeam 6 is:

[0061] The crossbeam 6 and the float 5 can be slidably connected:

[0062] A slide groove is opened at the end of the beam 6, and a slider matching the slide groove is installed on the float 5. Driven by the slider, the float 5 can move slightly along the end of the beam 6, which can better adapt to water level changes or wave influences, absorb part of the impact force of the waves, and increase the stability of the system.

[0063] The crossbeam 6 and the float 5 can be hinged:

[0064] The buoy 5 is connected to the beam 6 using a hinge, allowing the buoy to rotate or swing within a certain range, thereby absorbing the dynamic load caused by waves and reducing stress concentration in the structure.

[0065] The crossbeam 6 and the float 5 can be connected by a spring or a damper:

[0066] A spring is installed at the connection between the crossbeam 6 and the float 5 to connect the crossbeam 6 and the float 5 together through the spring, or a damper can be used as an intermediate connecting piece to achieve the connection between the crossbeam 6 and the float 5. The connection method of the spring or damper can effectively absorb and dissipate wave energy, reduce the impact of the float on the crossbeam, and protect the structural integrity.

[0067] The crossbeam 6 and the float 5 can be flexibly connected:

[0068] The float 5 can be tied to the crossbeam 6 by a flexible rope. The flexible rope mentioned in this embodiment can be a steel wire rope or a synthetic fiber rope.

[0069] It should be noted that the present device is not limited to the above-mentioned connection method that has been disclosed, as long as the connection between the crossbeam 6 and the float 5 can be achieved and the buoyancy effect of the float 5 on the crossbeam 6 can be realized.

[0070] Furthermore, in the embodiment of the present invention, the float 5 is arranged at the end of the beam 6 away from the hull 1, and can serve as an extension of the beam 6, and can directly bear part of the wind force, reduce the direct impact of the wind force on the hull, thereby protecting the hull from damage. At the same time, under extreme weather conditions, the float 5 can also play a certain buffering role, reducing the risk of damage to the wind turbine due to strong winds.

[0071] Furthermore, in the embodiment of the present invention, the structure of the float 5 is not limited, as long as it can satisfy the buffering effect.

[0074] Furthermore, in the embodiment of the present invention, the integrated structure of the float 5 extends along the side of the hull 1, closely connecting the multiple beams 6 together to form a stable side support system. This structural layout significantly enhances the hull's anti-rolling ability when encountering lateral external forces such as wind and waves, ensuring the stability of the wind turbine in severe sea conditions.

[0075] Furthermore, in the embodiment of the present invention, the continuity of the float 5 enables all the beams 6 on both sides of the hull and the power generation equipment arranged on the beams 6 to form a whole, which helps to reduce the shaking amplitude of the hull in the waves, allowing the wind turbine to operate more stably and reduce energy loss and equipment damage caused by shaking.

[0076] Furthermore, in the embodiment of the present invention, the float 5 provides a stable installation platform for the wind turbine by connecting the crossbeam 6. This stable layout helps to reduce the shaking of the wind turbine during operation, so that it can more effectively capture wind energy and convert it into electrical energy.
