Description

Technical Field

[0001] The utility model belongs to the technical field of offshore wind power foundations, and in particular relates to a multifunctional offshore wind power observation buoy. Background Art

[0002] With the growing global demand for renewable energy, offshore wind power, as a key component of clean energy, is becoming a key area for optimizing energy structures in various countries. Meteorological and hydrological observations for offshore wind farms are fundamental to their design, operation, and maintenance. These observations face numerous challenges, including the complex and volatile marine environment, high infrastructure costs, and the need for precise data monitoring. Traditional offshore wind power observation platforms often utilize floating or fixed foundations, but these structures have limitations in terms of adapting to extreme marine environments, improving monitoring accuracy, and reducing costs.

[0003] Based on this, this patent proposes a multifunctional offshore wind power observation buoy. Through the coordination of a slender truss and the center of gravity, the buoy can effectively reduce the wave load on the buoy and improve the stability of the buoy. It can provide a stable platform for various observation equipment, realize three-dimensional high-quality observation of ocean wind resources and ocean hydrology, and has huge advantages in structural reliability. Utility Model Content

[0004] In order to make up for the shortcomings of the existing technology, the purpose of this utility model is to provide a multifunctional offshore wind power observation buoy, which provides a stable platform for various observation equipment and realizes three-dimensional high-quality observation of ocean wind resources and ocean hydrology.

[0005] The multifunctional offshore wind power observation buoy comprises a truss, an observation platform arranged on the top of the truss, and a ballast block arranged at the bottom of the truss. The ballast block is used to lower the center of gravity of the buoy, and the truss is used to provide buoyancy; the ballast block is fixed to the seabed by a mooring cable.

[0006] Furthermore, a wind measuring instrument is provided on the observation platform, and a hydrological observation instrument is provided on the truss.

[0007] Furthermore, the ballast block is a spherical structure filled with high-density ballast material.

[0008] Furthermore, the truss includes a plurality of hollow tubes made of buoyancy material.

[0009] Furthermore, the truss includes a plurality of vertical supports between the observation platform and the ballast block, and a plurality of oblique supports are provided between two adjacent columns.

[0010] Furthermore, the columns and inclined supports are hollow pipes made of buoyancy materials.

[0011] Furthermore, four columns are provided between the observation platform and the ballast block.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] (1) The overall structure of the buoy in this application is slender, and compared with traditional buoys, the height difference between its center of gravity and center of buoyancy is greatly increased, thereby greatly improving the stability of the structure and providing a platform for various ocean observation equipment to achieve high-quality observation of ocean wind resources and ocean hydrology.

[0014] (2) The buoy of the present application is composed of a slender truss and a ballast block, that is, its overall structure extends into the water depth, which can significantly reduce the wave load on the structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 This is a schematic structural diagram of the utility model.

[0016] In the figure: 1-Observation platform, 2-Truss, 3-Ballast block, 4-Mooring cable. DETAILED DESCRIPTION

[0017] In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the present invention is further described below with reference to the accompanying drawings.

[0018] like Figure 1 As shown, a multifunctional offshore wind power observation buoy comprises a truss 2, an observation platform 1 mounted on top of the truss 2, and a ballast block 3 mounted on the bottom of the truss 2. The ballast block 3 is used to lower the buoy's center of gravity, while the truss 2 provides buoyancy for the buoy. The ballast block 3 is secured to the seabed via a mooring cable 4. The ballast block 3 is a spherical structure filled with a high-density ballast material. The truss 2 comprises several hollow tubes, preferably elongated hollow tubes, made of buoyant material.

[0019] It can be understood that through the cooperation between the truss 2 and the ballast block 3, the overall structure of the buoy of the present application is slender, and compared with traditional buoys, the height difference between its center of gravity and center of buoyancy is greatly increased, thereby greatly improving the stability of the overall structure.

[0020] During operation, the buoy is fixed to the seabed by a mooring cable 5. Observation instruments, including wind resource, wave, current and other observation instruments, can be arranged on the observation platform 1 and the truss 2. In a specific embodiment, a wind measuring instrument is set on the observation platform 1, and a hydrological observation instrument is set on the truss 2. Some energy facilities such as photovoltaic panels are installed to power the instruments to achieve three-dimensional observation of the marine environment.

[0021] Continue reading Figure 1As can be seen, the truss 2 comprises several vertical columns supporting the space between the observation platform 1 and the ballast block 3, with several diagonal supports positioned between adjacent columns. Both the columns and diagonal supports are hollow tubes made of buoyant material. In one embodiment, four columns are positioned between the observation platform 1 and the ballast block 3.

[0022] Considering that wave loads decay downward with water depth, this application designs truss 2 (i.e., the columns and diagonal supports) as slender hollow tubes. The buoy structure is extended toward the water depth, reducing the structural proportion of the buoy at the water surface and thereby reducing the wave loads on the buoy as a whole. Furthermore, the slender structural arrangement effectively increases the height difference between the center of gravity and the center of buoyancy, thereby increasing the restoring moment when the buoy is tilted by external forces, thereby enhancing the buoy's ability to withstand wind and wave waves.

[0023] 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.
