Description

Technical Field

[0001] The utility model relates to the technical field of offshore wind power generation, in particular to a floating power generation device. Background Art

[0002] Floating offshore wind turbines are a new type of wind power generation technology that converts wind energy into electricity through the rotation of wind turbine blades. The turbines are buoyed by a floating structure and anchored to the seabed by anchor chains. They offer excellent stability, are easy to transport, and can be used in deep waters.

[0003] However, the buoyancy of floating offshore wind turbines is prone to tipping over in strong winds and waves. In harsh sea conditions, the buoyancy is subject to significant wave impact, which can damage the exterior of the buoy. This, in turn, places higher demands on the buoyancy strength, increasing manufacturing costs. Furthermore, the connection between the buoyancy and the turbine is currently below sea level, significantly increasing the corrosion resistance requirements of the connection structure and the likelihood of corrosion below sea level. Furthermore, as wind turbine blades have gradually lengthened in recent years, using traditional methods would keep the blades at a low distance from the sea surface, impacting turbine safety and placing higher demands on corrosion protection.

[0004] Therefore, there is a need in the art for a wind power generation device that has strong stability and can increase the height of the wind turbine. Utility Model Content

[0006] The utility model provides a floating power generation device, comprising: a wind turbine, a floating body, and a counterweight. The floating body is ellipsoidal, with one end connected to the wind turbine and the other end connected to the counterweight along the long axis of the floating body. The floating body comprises three or more floating bodies, which are fixedly connected by connectors. The floating body is connected to the wind turbine via the connector, and the floating body is connected to the counterweight via a connecting ring.

[0007] Furthermore, there are four floating bodies, and the connecting parts include a vertical rod and four inclined rods. The four inclined rods are arranged in an "X" shape. The wind turbine is connected to the vertical rod, and the lower end of the vertical rod is connected to the inner end of each of the inclined rods at one point. The outer end of each of the inclined rods is respectively connected to one of the floating bodies.

[0008] Furthermore, the vertical rod is integrally connected to the tilt rod.

[0009] Furthermore, a cross bar is connected between two adjacent inclined bars.

[0010] Furthermore, the tilting rod is integrally connected to the cross bar.

[0013] Furthermore, the steel plate is in the shape of an evenly divided ellipsoid.

[0014] Furthermore, the thickness of the steel plate is 1.5 mm to 3 mm.

Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present utility model, "multiple" means two or more, unless otherwise clearly and specifically defined. In addition, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it 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 it can be an indirect connection through an intermediate medium, or it can be a communication between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0029] like Figure 1As shown, an embodiment of the present invention provides a floating power generation device, comprising: a wind turbine 1, a float 3, and a counterweight 5. The float 3 is ellipsoidal in shape, with the wind turbine 1 connected to one end and the counterweight 5 connected to the other end along its long axis. The float 3 comprises three or more floats 3, which are fixedly connected by connectors 2. The present invention utilizes three or more ellipsoidal floats 3 to form a buoyancy structure. Taking advantage of the ellipsoid's long axis, the counterweight 5 is used to pull one end of the long axis of the ellipsoidal float 3 underwater, ensuring that the other end remains stably above the surface. The wind turbine 1 is then installed on the side exposed above the surface. This improves structural stability while ensuring that the wind turbine 1 is installed high enough to avoid being submerged below sea level and eroded by seawater. By adjusting the weight of the counterweight 5 and the major-to-minor axis ratio of the float 3, the floating stability and performance of the floating power generation device can be adjusted.

[0030] Preferably, the float 3 is connected to the wind turbine 1 via a connector 2. To ensure corrosion resistance, the connector 2 can be made of seawater corrosion resistant material. Preferably, the connector 2 should also be made of high-strength material to have strong bending resistance and improve the overall connection strength of the equipment. In a specific embodiment, Figure 2 As shown, there are four floats 3, and the connecting member 2 includes a vertical rod and four inclined rods. The four inclined rods are arranged in an "X" shape. The wind turbine 1 is connected to the vertical rod, and the lower end of the vertical rod is connected to the inner end of each inclined rod at a point. The outer end of each inclined rod is connected to a float 3. Preferably, in order to improve the connection stability of the inclined rods, a cross bar can also be connected between two adjacent inclined rods. This embodiment utilizes four floats 3 to connect to form a quadrilateral support structure with high stability, and the number of floats 3 used is also reasonable, so the cost is not too high. It can be understood that according to the needs of actual working conditions, the number of floats 3 of the utility model can also be five or more, and can also be connected into polygons of other shapes, which can all fall within the scope of protection of the utility model.

[0031] This utility model utilizes multiple ellipsoidal floats 3 to form a buoyant structure, effectively reducing wave impact and improving stability. Furthermore, a counterweight 5 is attached to the lower end of the ellipsoidal structure, along its major axis, lowering the overall center of gravity and enhancing stability in adverse sea conditions. Furthermore, the wind turbine 1 and connector 2 are connected to the top of the floats 3, high above the water surface, reducing corrosion from seawater.

[0032] Preferably, the buoy 3 is connected to the counterweight 5 via a connecting ring 4. A chain of a certain length may be provided between the connecting ring 4 and the counterweight 5. The length of the chain and the weight of the counterweight 5 may be determined according to sea conditions and other conditions. The connecting ring 4 and the counterweight 5 are both made of seawater corrosion-resistant materials to provide good seawater corrosion resistance.

[0033] like Figure 3 and Figure 4 As shown, the float 3 is welded from steel plates 31. Preferably, the steel plates are thin plates with a thickness of 1.5mm to 3mm, which can ensure structural strength while not being too heavy, thereby ensuring the floating effect. The steel plates 31 here can be stainless steel, which has high strength and corrosion resistance and is suitable for making the float 3. It is understandable that the steel plates 31 here can also be made of other materials with good corrosion resistance, such as aluminum plates or copper plates. Preferably, the welds between the steel plates 31 are connected with reinforcing ribs 32 to increase the strength of the float 3 and improve the sealing of the weld joints. Further preferably, the steel plates 31 are in the shape of an evenly divided ellipsoid. The evenly divided ellipsoid is convenient for uniform processing and welding, and the weld shape is regular, which is conducive to improving the process level and saving processing and manufacturing costs.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
