Description

Technical Field

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

[0002] Floating offshore wind power is a wind power generation technology that converts wind energy into electrical energy through the rotation of wind turbine blades. Its wind turbine is provided with buoyancy by a floating body and fixed to the seabed by an anchor chain. It has good stability, is easy to transport and move, and can be used in ocean conditions with relatively deep water depths.

[0003] However, the floating body of the floating offshore wind power turbine is prone to tipping over in large waves and is greatly impacted by sea waves in harsh sea conditions, which will cause damage to the outside of the floating body. Therefore, higher requirements are imposed on the strength of the floating body, increasing the manufacturing cost. In addition, at present, the connection between the wind turbine floating body and the wind turbine is below the sea level, which greatly increases the requirement for the corrosion resistance of the connection structure and also increases the possibility of corrosion of the structure below the sea level. In addition, due to the gradual lengthening of wind turbine blades in recent years, if traditional methods are used, the distance between the blades and the sea surface is relatively low, which affects the safety of the wind turbine and also imposes higher requirements on the anti-corrosion of the wind turbine.

[0004] Therefore, there is a need in the art for a wind power generation device with strong stability and capable of increasing the height of the wind turbine. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a sandwich corrugated plate floating body power generation device with strong stability and capable of increasing the height of the wind turbine.

Among them, there are three or more floating bodies, and the floating bodies are fixedly connected to each other through connecting pieces. The floating body is connected to the wind turbine through the connecting piece.

[0007] Further, there are four floating bodies. The connecting piece comprises a vertical rod and four inclined rods. The four inclined rods are arranged in an "X" shape.

[0030] Such as Figures 1 to 4As shown in the figure, an embodiment of the present utility model provides a sandwich corrugated plate floating body power generation device, including: a fan 1 and a floating body 3. The floating body 3 is a cylinder with a hollow interior. The inner wall and the outer wall of the floating body 3 are both made of corrugated plates 5. Filling materials are poured between the inner wall and the outer wall. Sealing plates are arranged at both ends of the floating body 3. A fan 1 is connected to the top of the floating body 3. Among them, there are three or more floating bodies 3, and the floating bodies 3 are fixedly connected to each other through a connecting piece 2. The floating body 3 is connected to the fan 1 through the connecting piece 2.

[0031] The present utility model uses three or more floating bodies 3 to form a buoyancy structure, and installs a fan 1 on the side exposed above the water surface, which not only improves the structural stability, but also makes the installation position of the fan 1 high enough not to be submerged below the sea level and eroded by seawater.

[0032] The floating body 3 of the present utility model adopts a hollow structure, which can effectively reduce the overall weight of the floating body 3 and save manufacturing costs. Filling materials are poured between the inner wall and the outer wall as the counterweight of the floating body 3 to pull the bottom end of the floating body 3 into the bottom of the water, ensuring that the other end floats out of the water stably. By changing the type of filling materials, as well as the diameter and height of the floating body 3, the floating stability and performance of the floating body power generation device can be adjusted.

[0033] Both the inner wall and the outer wall of the present utility model are made of corrugated plates 5. Due to the unique "accordion effect", the corrugated plates 5 have a large out-of-plane stiffness, which not only retains the advantages of flat plates but also overcomes the disadvantages of flat plates, significantly reducing the out-of-plane deformation and increasing the shear yield strength.

[0034] Preferably, the filling material is concrete. Pouring concrete between the two layers of corrugated plates plays a connecting role and enhances its structural strength.

[0035] Preferably, the height of the floating body 3 is greater than the diameter of the floating body 3. The diameter of the floating body 3 is 20 - 40 m, and the height is 30 - 50 m. With such a design, the bottom end of the floating body 3 is more likely to be submerged in the bottom of the water, and the other end floats out of the water stably. Therefore, the installation position of the fan 1 installed on the top of the floating body 3 is high enough not to be submerged below the sea level and eroded by seawater.

[0036] Preferably, the floating body 3 is connected to the fan 1 through the connecting piece 2. To ensure the anti-corrosion performance, the connecting piece 2 can be made of anti-seawater corrosion materials. Preferably, the connecting piece 2 should also be made of high-strength materials to make it have strong anti-bending performance and improve the overall connection strength of the equipment.

[0037] In a specific embodiment, such as Figure 2As shown, the floating body 3 has four. The connecting member 2 includes a vertical rod and four inclined rods. The four inclined rods are arranged in an "X" shape. A wind turbine 1 is connected to the vertical rod. The lower end of the vertical rod is connected to the inner ends of the inclined rods at one point, and the outer ends of the inclined rods are respectively connected to a floating body 3. Preferably, the vertical rod and the inclined rods are integrally connected to increase the connection strength.

[0038] Preferably, in order to improve the connection stability of the inclined rods, a cross bar 4 can also be connected between two adjacent inclined rods. Preferably, the cross bar 4 and the inclined rods are integrally connected to increase the connection strength. In this embodiment, four floating bodies 3 are used to form a quadrilateral support structure, which has high stability, and the number of floating bodies 3 used is also reasonable, so that the cost will not be too high. It can be understood that according to the actual working conditions, the number of floating bodies 3 of the present invention can also be five or more, and can also be connected into polygons of other shapes, all of which fall within the protection scope of the present invention.

[0039] The present invention uses multiple floating bodies 3 to form a buoyancy structure, which can better reduce the impact of sea waves and improve stability. In addition, the wind turbine 1 and the connecting member 2 are connected to the top of the floating body 3, which is at a relatively high distance from the water surface, and can reduce the corrosion of seawater.

[0040] Preferably, the corrugated plates 5 forming the inner wall and the corrugated plates 5 forming the outer wall are arranged in an interleaved manner, a parallel manner or a relative manner. As Figure 4 shown, a relative arrangement manner is shown. The common waveforms of the corrugated plate 5 are sinusoidal, trapezoidal, broken line-shaped and rectangular, and the two waveforms of sinusoidal and trapezoidal are used more. It can be understood that the specific waveform to be adopted and the arrangement manner between the two layers of corrugated plates can be determined according to the situation.

[0041] Preferably, the materials of the sealing plate and the floating body 3 are both stainless steel, which have high strength and corrosion resistance, and can extend the service life of the sandwich corrugated plate floating body power generation device.

[0042] As Figure 4 shown, the corrugated plate 5 is made by welding steel plates. Preferably, the steel plate is a thin plate with a thickness of 1.5 mm to 3 mm, which can not only ensure the structural strength but also is not too heavy to ensure the floating effect.

[0043] 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 foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
