A floating wind turbine support platform

Abstract

This utility model discloses a floating wind turbine support platform, including side columns, a central column, and a center-of-gravity adjustment component. There are three sets of side columns, with the central column located in the middle. The center-of-gravity adjustment component is located between the three sets of side columns, and includes connecting pipes. The side columns are hollow structures, and the three sets of side columns are connected by connecting pipes that communicate with the upper ends of the side columns. A sway plate is fixed to the lower end of each side column, and a hollow cavity is formed at the upper end of the sway plate. The lower ends of the three sets of side columns communicate with the hollow cavity. An oily liquid is placed inside each side column. A vacuum pump is installed on the left side of the connecting pipe, and a solenoid valve is installed on the right side of the connecting pipe. In actual use, when the vacuum pump evacuates air from the upper end of a specific side column, the air pressure inside that side column decreases. The oily liquid in the high-pressure zone flows through the hollow cavity to the side column in the low-pressure zone under pressure. Combined with the control of the solenoid valve, the center of gravity of the platform is adjusted.

Description

Technical Field

[0001] This application relates to the field of floating platform technology, and more particularly to a floating wind turbine support platform. Background Technology

[0002] Wind turbines, as an important source of modern clean energy, generate electricity using wind power, offering advantages such as renewability and environmental friendliness. Offshore wind energy resources are abundant, making offshore wind turbine installation a common choice. However, due to the significant variations in water depth at sea, traditional fixed foundations are unsuitable, typically requiring the use of floating support platforms.

[0003] When there is a long-term stable wind direction and speed in certain sea areas, this continuous wind force will constantly exert a force on the platform to one side, thus causing the platform to be in a slight but stable tilt state for a long time.

[0004] In practical use, traditional floating support platforms for wind turbines, due to their fixed structure, cannot dynamically adjust their center of gravity, making them prone to tilting due to wind and waves. Because these platforms lack anti-tilt adjustment mechanisms, their center of gravity cannot be actively adjusted according to changes in external conditions, leading to instability and tilting issues in strong winds. This affects the operating efficiency of the wind turbine and increases the risk of equipment damage or even overturning.

[0005] Therefore, a floating wind turbine support platform is needed to solve the above problems. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this utility model provides a floating wind turbine support platform, which solves the problem mentioned in the background that, in windy environments, traditional floating wind turbine support platforms, due to their fixed structure, cannot dynamically adjust their center of gravity and are prone to tilting due to wind and waves.

[0007] To achieve the above objectives, this utility model provides a floating wind turbine support platform, comprising: side columns 1, a central column 2, and a center of gravity adjustment component 5. The side columns 1 are in three groups, and the three groups of side columns 1 are arranged in parallel and at equal intervals around each other. A central column 2 is arranged in the middle of the three groups of side columns 1, and a center of gravity adjustment component 5 is arranged between adjacent groups of side columns 1.

[0008] The center of gravity adjustment component 5 includes a connecting pipe 51. The side column 1 has a hollow structure. Two adjacent sets of side columns 1 are connected by the connecting pipe 51. The connecting pipe 51 communicates with the top of the side column 1. A sway plate 3 is fixed at the bottom of the side column 1. A hollow cavity 55 is opened at the top of the sway plate 3. The bottom of the three sets of side columns 1 communicates with the hollow cavity 55. An oily liquid 52 is provided inside the side column 1. A vacuum pump 54 is installed on one side of the connecting pipe 51, and an electromagnetic valve 53 is installed on the other side of the connecting pipe 51.

[0009] In some embodiments, the solenoid valve 53 is a normally closed solenoid valve.

[0010] In some embodiments, an inspection port 12 is provided at the upper end of the side column 1.

[0011] In some embodiments, the central column 2 is fixed to three sets of side columns 1 by a strut 4, and the three sets of side columns 1 are respectively fixed with struts 4 between them and the central column 2.

[0012] In some embodiments, reinforcing rings 11 are fixed at both the upper and lower ends of the outer side of the side column 1.

[0013] In some embodiments, the sway plate 3 is made of a high-density material, and the sway plate 3 is heavier than the side column 1.

[0014] This utility model provides a floating wind turbine support platform with the following advantages: In actual use, the platform's stability and wind resistance are significantly improved in windy environments through the integrated and innovative center of gravity adjustment components; Utilizing the hollow structure of the side columns and the fluidity of the oily liquid, when the vacuum pump evacuates air from the upper end of a specific side column, the air pressure inside that side column decreases, and the oily liquid in the high-pressure area flows through the hollow cavity to the side column in the low-pressure area under pressure. Combined with the control of the electromagnetic valve, the adjustment of the platform's center of gravity is achieved. Attached Figure Description

The accompanying drawings are for reference and illustration only and are not intended to limit the embodiments of this application.

[0025] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0026] Please see Figure 1-4 This utility model provides a technical solution: a floating wind turbine support platform, including side columns 1, a central column 2, and a center of gravity adjustment component 5. The side columns 1 are arranged in three groups, with the three groups of side columns 1 arranged in parallel and at equal intervals. A central column 2 is arranged in the middle of the three groups of side columns 1. The center of gravity adjustment component 5 is arranged between the three groups of side columns 1. The center of gravity adjustment component 5 includes a connecting pipe 51. The side columns 1 are hollow structures. The three groups of side columns 1 are connected by the connecting pipe 51. The connecting pipe 51 communicates with the upper end of the side column 1. A sway plate 3 is fixed to the lower end of the side column 1. A hollow cavity 55 is opened at the upper end of the sway plate 3. The lower ends of the three groups of side columns 1 communicate with the hollow cavity 55. An oily liquid 52 is placed inside the side column 1. A vacuum pump 54 is installed on the left side of the connecting pipe 51, and an electromagnetic valve 53 is installed on the right side of the connecting pipe 51.

[0027] During operation, the connecting pipe 51 connects to three sets of side columns 1, allowing the oily liquid 52 inside to circulate among them. By adjusting the air pressure inside different side columns 1, the flow direction of the oily liquid 52 can be controlled. The vacuum pump 54 is used to evacuate air from the upper part of a specific side column 1, changing its internal air pressure. By controlling the opening and closing of the solenoid valve 53, the adjusted position of the oily liquid 52 can be maintained by air pressure. The sway plate 3 reduces the impact of waves on the platform. The oily liquid 52 serves as the medium for center of gravity adjustment; its flow among the three sets of side columns 1 changes the platform's center of gravity position.

[0028] The solenoid valve 53 is a normally closed solenoid valve. When not in use, the normally closed solenoid valve 53 remains closed, which means that when there is no need for regulation, the valve will not consume electrical energy to maintain the open state, thus reducing energy consumption.

[0029] An inspection port 12 is provided at the upper end of the side column 1. The inspection port 12 provides a direct passage into the interior of the side column 1, making it convenient to inspect, maintain and perform necessary repairs on the internal structure, connectors, oily liquid 52 and other components of the side column 1.

[0030] The central column 2 is fixed to the three sets of side columns 1 by the struts 4. The struts 4 are fixed between the three sets of side columns 1. The struts 4 provide additional support to ensure that the side columns 1 can be firmly fixed around the central column 2, forming a stable overall structure.

[0031] Reinforcing rings 11 are fixed to the upper and lower ends of the outer side of the side column 1. As an external reinforcement structure of the side column 1, the reinforcing rings 11 can significantly improve the compressive, bending and torsional resistance of the side column 1. Since the side column 1 is a hollow structure and there may be stress concentration caused by air pressure difference inside, the reinforcing rings 11 can effectively disperse these stresses and prevent the side column 1 from deforming or being damaged.

[0032] The sway plate 3 is made of high-density material and is heavier than the side column 1. The sway plate 3 helps to lower the center of gravity of the platform, thereby increasing the stability of the entire platform.

[0033] As an embodiment of this utility model: When adjusting the center of gravity of the floating wind turbine support platform, firstly, for the side column 1 that needs adjustment, the corresponding vacuum pump 54 is started to evacuate air from the upper end of the side column 1, adjusting the air pressure inside the side column 1. As the vacuum pump 54 operates, the air pressure inside the high-pressure side column 1 is relatively high. Under the action of the pressure difference, the oily liquid 52 will begin to flow through the hollow cavity 55 to the low-pressure side column 1, thereby achieving the adjustment of the platform's center of gravity. The normally closed solenoid valve 53 remains closed when not in use, which means that the valve will not consume electrical energy to maintain the open state when there is no adjustment requirement, reducing energy consumption. Thus, the center of gravity adjustment of the floating wind turbine support platform is completed.

[0034] The technical solutions described in the embodiments of this application can be combined arbitrarily without conflict.

[0035] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
