Technical Field
[0001] This invention relates to the field of offshore wind power generation technology, and particularly to a lift-type offshore wind power station. Background Technology
[0002] Offshore wind power stations are a new type of energy source that uses offshore wind resources to generate electricity. Wind power generation converts the kinetic energy of wind into electrical energy. As a clean and renewable energy source, wind energy has attracted the attention of countries around the world to areas with abundant wind resources, especially given the increasingly severe situation of oil resources.
[0003] However, existing lift-type offshore wind power stations still have the following problems: 1. Due to the harsh marine environment, the existing equipment of existing lift-type offshore wind power stations has low adaptability to the marine environment and low practicality; 2. Existing offshore wind power stations have high equipment costs due to various reasons, which prevents them from being put into use on a large scale; 3. Existing offshore wind power stations have limited technology for deep-sea wind power stations, that is, wind power stations with water depths greater than 50 meters, and the existing equipment has low practicality. Summary of the Invention
[0004] The main objective of this invention is to provide a lift-type offshore wind power station, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:
[0006] A liftable offshore wind power station includes a foundation frame. First connecting blocks are fixedly connected to the upper left and upper right ends of the foundation frame, and first anchor chains are sleeved within each of the two first connecting blocks. Anchor blocks are fixedly connected to the ends of the two first anchor chains furthest from the first connecting blocks. A connecting seat is fixedly connected to the middle of the upper end of the foundation frame, and a first tower is fixedly connected to the middle of the upper end of the connecting seat. A first wind turbine is fixedly connected to the upper end of the first tower, and first blades are fixedly connected to the output end of the first wind turbine. Four liftable floats are symmetrically and equidistantly fixed to the upper end of the foundation frame.
[0007] Preferably, the lifting float includes a hinge shaft, with a lower lifting lug and an upper lifting lug movably interposed on the outer surface of the hinge shaft. A floating mechanism is fixedly connected to the upper end of the upper lifting lug, and a central column is fixedly interposed in the middle of the floating mechanism. The lower lifting lug is fixedly connected to the base frame.
[0008] Preferably, the floating mechanism includes a lower base and an upper base. Two connecting rings are fixedly connected to the opposite surfaces of the lower base and the upper base, and a bladder is installed between the two connecting rings. A control mechanism is fixedly connected to the right end of the upper base. A second tower is fixedly connected to the middle of the upper end of the lower base. A second fan is fixedly connected to the upper end of the second tower. A second blade is fixedly connected to the output end of the second fan. The lower base is fixedly connected to the upper lifting lug.
[0009] Preferably, the intermediate column is fixedly connected between the lower base and the upper base.
[0010] Preferably, the control mechanism includes a wave detector, an air compressor is fixedly connected to the upper end of the wave detector, an air storage tank is fixedly connected to the left end of the air compressor, an air filling and emptying valve group is fixedly connected to the left end of the air storage tank, a connecting pipe is fixedly connected to the middle of the lower end of the air filling and emptying valve group, and the wave detector is fixedly connected to the upper base.
[0011] Preferably, the gas storage tank and the gas filling / discharging valve assembly are both fixedly connected to the upper base, and the connecting pipe is connected through the upper base.
[0012] Preferably, the capsules are all configured with a structure of cylindrical ends and a spherical middle section.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. This invention uses an inflatable structure for the lifting float. By setting a second tower, a small second fan and second blades are installed on the second tower to achieve lightweight power generation. The electricity generated mainly powers the air compressor, which stores the compressed gas in an air tank. When the wave detector detects severe sea conditions or its height exceeds the set height difference, the automatic control mechanism inflates or deflates the float, thereby changing its shape and achieving overall lifting and lowering. This allows it to avoid sea condition risks or adjust its overall attitude, thus adapting to severe sea conditions and improving the practicality of the equipment.
[0015] 2. Since each liftable buoy is equipped with a small generator on its upper part, it can independently form a power generation and gas charging and discharging control system. The liftable buoy can be configured and used as an independent offshore wind power station. In sea areas with suitable conditions, it can be deployed in large numbers in this way to form a small wind farm of a certain scale and improve the efficiency of offshore wind power generation.
[0016] 3. By improving the counterweight of the lower part of the liftable buoy and fixing its upper part to the dock with fixed cables, a ship berthing fender with power generation function is constructed. It can be used in situations where underwater hull berthing is required. The wind turbine part on the upper part can not only supply electricity, but also install warning lights on the wind turbine to enable navigation of ships at night. At the same time, it can be used as a multi-functional inflatable fender configuration for large oil tankers to provide power supply for ships during long-term barge operations, saving ship fuel. It can generate wind power and be used for fendering at the same time, making it highly practical. Attached Figure Description

[0026] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0027] like Figure 1-6 As shown, the liftable offshore wind power station includes a base frame 1. The upper left and upper right ends of the base frame 1 are fixedly connected to first connecting blocks 2, and first anchor chains 3 are sleeved in both first connecting blocks 2. Anchor blocks 4 are fixedly connected to the ends of the two first anchor chains 3 away from the first connecting blocks 2. A connecting seat 5 is fixedly connected to the middle of the upper end of the base frame 1. A first tower 7 is fixedly connected to the middle of the upper end of the connecting seat 5. A first wind turbine 8 is fixedly connected to the upper end of the first tower 7. A first blade 9 is fixedly connected to the output end of the first wind turbine 8. Four liftable floats 6 are fixedly connected symmetrically at equal intervals to the upper end of the base frame 1.
[0028] The lifting float 6 includes a hinge shaft 61, with a lower lifting lug 62 and an upper lifting lug 63 movably connected to the outer surface of the hinge shaft 61. A floating mechanism 64 is fixedly connected to the upper end of the upper lifting lug 63, and a central column 65 is fixedly connected to the middle of the floating mechanism 64. The central column 65 is designed as a rigid structure to ensure structural strength meets the requirements of the rocking condition. Simultaneously, the enclosed body provides emergency buoyancy in the event of damage to the float 644. The lower lifting lug 62 is fixedly connected to the base frame 1. The floating mechanism 64 includes a lower base 641 and... The upper base 642, lower base 641, and upper base 642 are each fixedly connected to two connecting rings 643 on opposite sides, and a bladder 644 is installed between the two connecting rings 643. A control mechanism 645 is fixedly connected to the right end of the upper base 642. A second tower 646 is fixedly connected to the middle of the upper end of the lower base 641. A second fan 647 is fixedly connected to the upper end of the second tower 646. A second blade 648 is fixedly connected to the output end of the second fan 647. The lower base 641 is fixedly connected to the upper lifting lug 63. Together, the lower lifting lug 62 and upper lifting lug 63 on the lower base 641 are rigidly connected to the foundation frame 1 via a hinge shaft 61, which can accommodate the swaying to meet the tilting requirements under the influence of waves; the intermediate column 65 is fixedly connected between the lower base 641 and the upper base 642; the control mechanism 645 includes a wave detector 51, an air compressor 52 is fixedly connected to the upper end of the wave detector 51, an air tank 53 is fixedly connected to the left end of the air compressor 52, and an air filling and emptying valve assembly 54 is fixedly connected to the left end of the air tank 53. A connecting pipe 55 is fixedly connected to the lower middle part of the 54, and the wave detector 51 is fixedly connected to the upper base 642; the gas storage tank 53 and the gas filling and discharging valve group 54 are both fixedly connected to the upper base 642, and the connecting pipe 55 is connected to the upper base 642 through the pipe; the bladder 644 is designed with a structure of cylindrical at both ends and bulging in the middle. The bladder 644 at both ends is connected to the flange cylinders protruding from the lower base 641 and the upper base 642 through the connecting ring 643. When the bladder 644 is damaged, it can be replaced as a whole.
[0029] It should be noted that this invention is a liftable offshore wind power station. The entire power station is lowered by a liftable float 6, which is an inflatable structure. A second tower 646 is installed, on which a small second wind turbine 647 and second blades 648 are mounted, achieving lightweight power generation. The generated electricity primarily powers the air compressor 52. When the air compressor 52 is started, it directs air into a fixedly connected air storage tank 53 for storage. The inflation and deflation valve group 54 allows for inflation and deflation of the bladder 644 between the lower base 641 and the upper base 642 via a connecting pipe 55. When the wave detector 51 detects severe sea conditions or its height exceeds a set elevation difference, the automatic control mechanism 645 inflates or deflates the buoy 644, thereby changing its shape, raising or lowering it, avoiding sea condition risks, or adjusting its overall attitude. This is achieved by controlling the pressure to control the volume of the buoy 644, thus changing the displacement and allowing it to rise and fall in the water. Three or four symmetrically arranged buoys 6 surround the first blower 8. Since each buoy 6 has a small generator installed on its upper part, they can independently form a power generation and inflation / deflation control system. The lifting float 6 can be configured as an independent offshore wind power station, which is a scaled-down version of the SPAR type of offshore floating power station, providing a reference and test template for its large-scale development. In suitable sea areas, it can be deployed in large numbers in this way to form a small-scale wind farm. At the same time, by improving the counterweight of the lower part of the lifting float 6 and fixing its upper part to the side of the dock 14 with the fixing cable 15, a ship berthing fender with power generation function is constructed. Its internal inflation pressure is low and the elasticity of the bladder 644 is large, which can effectively buffer the berthing energy of the ship. Due to its depth in the water, With its large underwater buffer contact surface, this structure is particularly suitable for situations requiring underwater hull berthing, such as submarines, semi-submersible marine platforms, and other special vessels. The wind turbine section on top can supply electricity and also be equipped with warning lights for nighttime navigation of the vessel. When the liftable float 6 is used as an inflatable fender, it can be used for ship-to-ship berthing operations instead of being installed on the dock 14. If the liftable float 6 is designed to be miniaturized, it can be used as a multi-functional inflatable fender configuration for large oil tankers. At the same time, it can be installed on both sides of the ship to generate wind power, providing power for long-term barge operations and saving fuel for the ship.
