Description

Technical Field

[0001] This utility model relates to the field of offshore wind power generation technology, specifically to a device that can adjust the height of a floating offshore wind turbine generator in real time. Background Technology

[0002] The principle of wind power generation is to use wind power to drive the rotation of wind turbine blades, and then use a speed increaser to increase the rotation speed, thereby causing a generator to generate electricity. Offshore wind power generation devices can be supported in two ways: fixed and floating. However, fixed devices are only suitable for nearshore waters due to their limited water depth. Driven by the need for development in deep waters, floating offshore generators are gradually becoming the mainstream. A floating offshore power generation device consists of a support platform floating on the sea, a wind turbine mounted on the support platform, and a support mast connecting the support platform and the wind turbine.

[0003] In existing technologies, the height of a wind turbine relative to the sea level is usually kept relatively constant. However, as the wind force at sea changes continuously, the height of the wind turbine relative to the sea level cannot adapt to the changes in wind force, resulting in insufficient stability of the wind turbine. Utility Model Content

[0004] Based on the technical problems existing in the prior art, this utility model provides a device that can adjust the height of a floating offshore wind turbine in real time. It can adjust the height of the turbine relative to the sea level according to the size of the wind and waves, so that the height of the turbine relative to the sea level can adapt to changes in wind force, thereby improving the stability of the turbine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A device for real-time adjustment of the height of a floating offshore wind turbine includes a support platform, a buoyancy component, a support rod, and a wind turbine mounted on the support platform, and a power component interconnected with the buoyancy component. The buoyancy component includes a floating chamber mounted on the support platform and a vent pipe connecting the floating chamber and the power component. The floating chamber is connected to the support rod and has a water passage hole. The power component includes an air pump mounted on the support platform, and the air outlet of the air pump is connected to the vent pipe.

[0007] A further improvement of this utility model is that the support platform is provided with an installation hole for the support rod to pass through, the wall of the installation hole is provided with a sliding groove, the support rod is provided with a sliding block adapted to the sliding groove, and the sliding block is slidably disposed in the sliding groove.

[0008] A further improvement of this invention is that the central axis of the mounting hole is perpendicular to the support platform, and the central axis of the sliding groove is parallel to the support platform.

[0009] A further improvement of this invention is that a support frame is provided on the outer side of the floating chamber.

[0010] A further improvement of this utility model is that the support frame is provided with several gravity blocks.

[0011] A further improvement of this invention is that the power assembly further includes a water level sensor disposed on the floating chamber and a control valve disposed at the air outlet of the air pump, wherein the water level sensor is electrically connected to the control valve.

[0012] A further improvement of this utility model is that the peripheral sidewall of the support rod is provided with several support baffles.

[0013] A further improvement of this invention is that the bottom surface of the supporting baffle is parallel to the supporting platform.

[0014] A further improvement of this invention is that it also includes several power submarine cables disposed at the bottom of the support platform.

[0015] A further improvement of this invention is that a counterweight is provided at the end of the power submarine cable away from the support platform.

[0016] Compared with the prior art, the present invention has at least the following beneficial technical effects:

[0017] This utility model provides a device for real-time adjustment of the height of a floating offshore wind turbine generator, comprising a support platform, a buoyancy component mounted on the support platform, a support rod, and a wind turbine, as well as a power component interconnected with the buoyancy component. The buoyancy component includes a floating chamber mounted on the support platform and a vent pipe connecting the floating chamber and the power component. The floating chamber is connected to the support rod and has a water passage. The power component includes an air pump mounted on the support platform, with the air pump's outlet connected to the vent pipe. When the sea conditions change, the air pump draws or pumps air into the floating chamber, causing a change in the air-to-water ratio within the floating chamber. This allows for adjustment of the wind turbine's height relative to the sea level according to the size of the waves, enabling the wind turbine's height to adapt to changes in wind force and thus improving the wind turbine's stability.

[0031] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0032] Example 1

[0033] Please refer to Figure 1-3 The present invention provides a device 100 for real-time adjustment of the height of a floating offshore wind turbine generator set, including a support platform 10, a buoyancy component 20, a support rod 30 and a wind turbine 40 disposed on the support platform 10, and a power component 50 interconnected with the buoyancy component 20, wherein the support rod 30 and the wind turbine 40 are relatively fixed.

[0034] The support platform 10 is provided with a mounting hole 11 for the support rod 30 to pass through, and the wall of the mounting hole 11 is provided with a sliding groove 12. Specifically, the central axis of the mounting hole 11 is perpendicular to the support platform 10, and the central axis of the sliding groove 12 is parallel to the support platform 10, so that the support rod 30 and the fan 40 always remain vertical relative to the support platform 10 during the height adjustment process, reducing the swaying of the support rod 30 and the fan 40 and improving the stability of the support rod 30 and the fan 40.

[0035] The buoyancy assembly 20 includes a floating chamber 21 disposed on the support platform 10 and a vent pipe 22 connecting the floating chamber 21 and the power assembly 50. Specifically, in this embodiment, the floating chamber 21 is a hollow cuboid structure.

[0036] The floating chamber 21 is connected to the support rod 30. The floating chamber 21 is provided with a water passage hole 211. Specifically, in this embodiment, the water passage hole 211 is located at the bottom of the floating chamber 21. During use, seawater enters the floating chamber 21 through the water passage hole 211. A support frame 212 is provided on the outer side of the floating chamber 21. Several gravity blocks 213 are provided on the support frame 212 to increase the self-weight of the floating chamber 21, making it less prone to capsizing due to waves and improving the stability of the floating chamber 21.

[0037] The power assembly 50 includes an air pump 51 mounted on the support platform 10, with its outlet connected to a vent pipe 22. The power assembly 50 also includes a water level sensor (not shown) mounted on the floating chamber 21 and a control valve 52 located at the air outlet of the air pump 51. The water level sensor and control valve 52 are electrically connected. Specifically, in this embodiment, a float-type water level sensor is used, and its housing is waterproof. The control valve 52 is a three-way valve. The water level sensor can obtain the water volume within the floating chamber 21 and, in conjunction with the control valve 52, facilitates the air pump 51 in controlling the amount of air pumped from the floating chamber 21.

[0038] When applied, the technical solution in this embodiment can be used in conjunction with existing marine wind and wave detection systems. When the marine wind and wave detection system detects changes in sea wind force, the air pump 51 in this application draws air outward to increase the weight of the device 100 that can adjust the height of the floating offshore wind turbine generator in real time. Alternatively, the air pump 51 in this application can supply air inward, thereby reducing the weight of the device 100 that can adjust the height of the floating offshore wind turbine generator in real time.

[0039] The support rod 30 has several support baffles 31 on its peripheral sidewall. The bottom surface of the support baffles 31 is parallel to the support platform 10, so that the support rod 30 and the fan 40 can always remain vertical relative to the support platform 10 during the height adjustment process, reducing the swaying of the support rod 30 and the fan 40, thereby further improving the stability of the support rod 30 and the fan 40.

[0040] The side wall of the support rod 30 is also provided with a sliding block 32 that is adapted to the sliding groove 12. The sliding block 32 is slidably disposed in the sliding groove 12 so that the support rod 30 is not easily dislodged from the support platform 10.

[0041] The device 100, which allows for real-time height adjustment of the floating offshore wind turbine generator, also includes several power submarine cables 60 mounted at the bottom of the support platform 10. A counterweight 61 is provided at the end of each power submarine cable 60 furthest from the support platform 10. When placing the wind turbine 40, the power submarine cables 60 are first fixed relative to the seabed. The counterweight 61 increases the weight, reducing the impact of sea waves on the support platform 10 and the wind turbine 40, and minimizing the impact of the swaying of the support platform 10 and the wind turbine 40 on wind power generation efficiency.

[0042] Example 2

[0043] Please refer to Figure 1-3This utility model provides a device 100 for real-time adjustment of the height of a floating offshore wind turbine generator. When the sea waves change, the air pump 51 draws or supplies air into the floating chamber 21, causing the air and water content ratio in the floating chamber 21 to change. This changes the weight of the entire device 100, which is capable of real-time adjustment of the height of the floating offshore wind turbine generator. As a result, the floating chamber 21 moves the wind turbine 40 up and down relative to the sea level, thereby adjusting the height of the wind turbine 40 relative to the sea level according to the wind force. This allows the height of the wind turbine 40 relative to the sea level to adapt to changes in wind force, thereby improving the stability of the wind turbine.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
