Description

Technical Field

[0001] This utility model belongs to the field of marine observation buoy technology, specifically relating to a three-dimensional marine hydrological observation buoy device. Background Technology

[0002] With the continuous growth of global demand for renewable energy, offshore wind power, as an important component of clean energy, is gradually becoming a key direction for optimizing the energy structure of various countries. Marine hydrological observation is fundamental to the design, operation, and maintenance of wind farms, and faces numerous challenges, including a complex and ever-changing marine environment, the high cost of constructing observation platforms, and the need for precise data monitoring.

[0003] Traditional marine hydrological observation buoys mostly adopt disc or columnar structure designs, but these structures have certain limitations in dealing with extreme marine environments, improving monitoring accuracy and reducing costs: (1) poor hydrodynamic performance, disc structures are prone to large rolling motion in waves, and columnar structures are prone to vortex-induced vibration; (2) fixed instrument mounting depth, making it impossible to achieve three-dimensional observation; (3) complex mooring system, and conventional four-corner mooring methods are difficult to recover. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides a three-dimensional marine hydrological observation buoy device, which adopts an innovative streamlined floating body structure design and is combined with a single-point mooring system to improve the hydrodynamic performance of the buoy.

[0005] The specific technical solution of this utility model is as follows:

[0006] The aforementioned three-dimensional marine hydrological observation buoy device includes a buoy, a mooring cable, and anchors. The buoy has an ellipsoidal head, a cylindrical or conical gradually changing cross-section in the middle, and a conical tapering tail. The head is connected to the mooring cable, and several observation instruments are mounted on the mooring cable.

[0007] Furthermore, the buoy has a teardrop-shaped structure with a length L to maximum diameter D ratio of 4:1, an ellipsoidal segment length of L / 4, a tapered gradually changing cross-section segment length of L / 2, a tapered contraction segment length of L / 4, and a cone angle of 15°.

[0008] Furthermore, the buoy has a submarine-type structure with a length L to maximum diameter D ratio of 4:1, an ellipsoidal segment length of L / 4, a cylindrical gradually changing cross-section segment length of L / 2, a conical contraction segment length of L / 4, and a cone angle of 15°.

[0009] Furthermore, the outer surface of the buoy is provided with flow-guiding fins.

[0010] Furthermore, the observation instruments are arranged at intervals along the length of the mooring cable to observe the marine hydrological conditions at different depths.

[0011] Furthermore, the anchor is a holding anchor.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] (1) The buoy of this application can provide a stable platform for various marine observation equipment, and the observation instruments can be arranged at different water depths to realize three-dimensional high-quality marine hydrological observation at different water depths.

[0014] (2) The buoy in this application adopts a submarine / teardrop shape, which can effectively reduce the load of the incoming flow on the buoy; with single-point mooring, the buoy can rotate with the incoming flow, so that the load of the buoy is at the minimum level, which greatly improves the stability and reliability of the structure and extends the service life of the buoy.

[0015] (3) The anchors are holding anchors, which are similar to the anchoring and raising of the ship. They can be easily anchored and recycled, making the construction and recycling of the whole system very convenient and helping the whole system to be reused. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0020] like Figure 1 and Figure 2 As shown, a three-dimensional marine hydrological observation buoy device includes a buoy 1, a mooring cable 2, and an anchor 4. The head of the buoy 1 is an ellipsoidal section, the middle section is a cylindrical or conical gradually changing section, and the tail is a conical contraction section. The head is connected to the mooring cable 2, and several observation instruments 3 are installed on the mooring cable 2.

[0021] Mooring cable 2 is fixed to the seabed by anchors 4, and buoy 1 floats on the sea surface under the action of buoyancy. Buoy 2 is equipped with energy facilities such as batteries to provide power for observation instruments 3, enabling three-dimensional observation of the marine hydrological environment. Compared with traditional buoys, this buoy structure can effectively reduce the marine load it receives, and its construction and recovery are very convenient. It can effectively improve the stability, reliability and service life of the observation system, and reduce the system cost. In addition, a vertical observation matrix is ​​constructed to achieve high-quality three-dimensional observation of marine hydrology.

[0022] Continue reading Figure 1 Buoy 1 has a submarine-type structure with a length L to maximum diameter D ratio of 4:1. The ellipsoidal section is L / 4 of the length; the cylindrical gradually changing section is L / 2 of the length; and the conical contraction section is L / 4 of the length with a cone angle of 15°. (Continue reading...) Figure 2 Buoy 1 has a teardrop-shaped structure with a length L to maximum diameter D ratio of 4:1. The ellipsoidal section is L / 4 long; the tapered gradually changing section is L / 2 long; the tapered contracting section is L / 4 long and has a cone angle of 15°.

[0023] The submarine / teardrop-shaped buoy 1 can effectively reduce the ocean current load on the structure, thereby improving the stability of the structure; in combination with the single-point mooring, the buoy 1 can rotate around the anchor point in the direction of the wave and current load, always keeping the structure at the level of minimum load.

[0024] The observation instruments 3 are spaced apart along the length of the mooring cable 2 and fixed to it. Distributed along the water depth, they enable observation of marine hydrological conditions at different depths, including the measurement of ocean dynamic parameters such as waves and currents, and the observation of marine environmental parameters such as oxygen content and temperature. The observation signals are transmitted to a storage structure within the buoy 1 via cables running along the mooring cable 2 for storage. The single-point mooring system and the use of submarine / teardrop shaped buoys ensure that the observation instruments remain stable within a certain depth range without significant fluctuations.

[0025] Anchor 4 uses a holding anchor. During construction, the buoy is simply thrown into the sea, and the holding anchor will sink to the seabed. Under the action of the ocean current, the holding anchor will be subjected to horizontal force and automatically embed itself into the seabed and hold firmly. In addition, the holding anchor is very easy to retrieve, similar to the anchoring and retrieving of a ship. After completing the observation mission in one sea area, it can be easily transferred to another sea area, thus realizing the reuse of the buoy.

[0026] In addition, the outer surface of the buoy 1 of this application is provided with flow guide fins 5 to suppress vibrations caused by lateral flow.

[0027] In summary, this application constructs a complete marine hydrological observation buoy device through a submarine / teardrop-shaped buoy 1, single-point mooring, holding anchor, observation instruments 3 fixed on the mooring cable 2, and auxiliary facilities such as the power supply inside the buoy 1. This achieves the minimum load on the observation buoy, significantly improving the stability, reliability, and service life of the structure. In addition, the observation instruments 3 are directly deployed at different water depths, enabling hydrological observation at different depths and providing excellent observation results. Finally, the use of the holding anchor makes the construction and recovery of the entire system very convenient.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
