Technical Field
[0001] The utility model relates to the technical field of offshore wind power generation, in particular to a self-moving offshore floating wind power generator set. Background Art
[0002] Currently, offshore floating wind turbines are primarily towed from the dock to their location by tugboats, then secured with mooring chains attached to the exterior of the floating foundation. When the turbines need to be moved, they must be towed by tugboats. To reduce transportation costs, a self-propelled offshore floating wind turbine is proposed, in which an ocean current generator is fixed below the surface of the floating foundation. Depending on the scenario, the current generator can both generate electricity from the ocean current and serve as a propeller for the floating foundation. Utility Model Content

[0005] Preferably, the axial flow direction of the ocean current generator can be rotated in any direction, that is, 360°, so that the floating foundation can rotate in place or move straight.
[0006] Preferably, the ocean current generator is electrically connected to a wind turbine, so that the electric energy generated by the ocean current generator is combined with the wind turbine and sent out together.
[0007] Preferably, the ocean current generator is assembled by a low-speed permanent magnet direct-drive generator and corrosion-resistant high-strength metal or non-metal blades.
[0008] Preferably, the metal surface of the ocean current generator is covered with corrosion-resistant, wear-resistant paint or non-metallic coating.
[0009] Preferably, the depth range of the ocean current generator is from below the water surface to above the seabed surface.
[0010] Preferably, there are multiple ocean current generators.
[0011] Preferably, it further comprises a wave energy generator, wherein the wave energy generator is fixed on a floating foundation.
[0012] Preferably, the wave energy generator is electrically connected to a wind turbine, so that the electric energy generated by the wave energy generator is combined with the wind turbine and sent out together.
[0013] Preferably, there are a plurality of wave energy generators surrounding a floating foundation.
[0014] Compared with the prior art, the present invention has the following advantages and beneficial effects:
[0015] The utility model integrates a wind turbine, an ocean current generator and a wave energy generator, so that wind energy, ocean current energy and wave energy are used to generate electricity in normal times. When the wind turbine needs to be moved, the ocean current generator can be powered by reverse thrust to achieve self-movement. To a certain extent, it does not rely on towing, thereby effectively reducing transportation costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 2 This is the second structural diagram of a self-movable offshore floating wind turbine generator set (reflecting the reverse thrust of the ocean current generator). DETAILED DESCRIPTION
[0018] The present invention will be described in further detail below with reference to the embodiments and drawings, but the embodiments of the present invention are not limited thereto.
[0019] Example 1

[0021] Specifically, the axial direction of the ocean current generator 3 can be rotated in any direction, that is, 360 degrees. When the floating wind turbine generator set needs to be moved to another location, the reverse thrust generated by the ocean current generator 3 after power is turned on can be used (see FIG. Figure 2 The floating foundation 2 can be driven to move by itself by applying different electric energies to the ocean current generator 3, so that the floating foundation 2 can rotate in place, move straight, etc. Figure 2 shown.
[0022] Specifically, the ocean current generator 3 and the wave energy generator 4 are electrically connected to the wind turbine 1 respectively. During normal operation, the ocean current generator 3 generates electricity normally under the action of the water flow, and the wave energy generator 4 generates electricity normally under the action of the waves. The electricity they generate is combined with the wind turbine 1 and sent out together.
[0023] Specifically, the ocean current generator 3 is assembled by a low-speed permanent magnet direct drive generator and corrosion-resistant high-strength metal or non-metallic blades, and its metal surface is covered with corrosion-resistant and wear-resistant paint or non-metallic coating.
[0024] Example 2
[0025] The difference from Example 1 is that the self-movable offshore floating wind turbine generator set described in this embodiment does not include a wave energy generator (not shown in the figure).
