Description

Technical Field

[0001] The utility model relates to a spindle-shaped neutral buoy suitable for fixed-depth hovering observation in the middle and upper oceans, belonging to the technical field of ocean monitoring. Background Art

[0002] As the most important observation platform for the newly developed long-term observation / monitoring of the mid- and upper-ocean environment at fixed depth, long-term safe on-site duty and scheduled surfacing communications require a neutral buoy that can hover at a specific water depth and have the ability to rise and fall. However, it is necessary to master the key core technologies of the neutral buoy in order to improve the overall ocean observation capabilities and achieve the best coordination of related technologies.

[0003] Lagrangian method is a major form of ocean observation. Sea surface drifting buoys, profiling buoys and neutral buoys are the three most commonly used Lagrangian observation platforms, which are mainly suitable for observing ocean parameters by tracking the movement of fluid particles. Compared with sea surface drifting buoys, although profiling buoys and neutral buoys have the disadvantage of weak real-time communication capabilities, they have the advantages of long-term concealment and not easy to be destroyed; compared with profiling buoys, the observation depth range of neutral buoys is limited, but while carrying out profiling observations, it can also realize hovering observations of fixed depth layers in the middle and upper oceans. As neutral buoys, existing profiling buoys are mostly cylindrical, while deep profiling buoys are mostly spherical. Due to design defects, the existing neutral buoys rise and fall relatively slowly, have large resistance in the water, weak turbulence resistance, and insufficient movement stability, and have failed to give full play to their capabilities as observation platforms and communication platforms.

[0004] For example, the Chinese utility model patent application with publication number CN208813456U discloses a deep-sea self-sustaining profile intelligent buoy, whose buoy shape is spherical; another example is the Chinese utility model patent application with publication number CN219134434U, which discloses a lightweight deep-sea ARGO buoy for marine environment observation, whose overall shape is cylindrical; another example is the Chinese utility model patent with publication number CN209553441U, which discloses an ARGO buoy based on wave energy, whose main pressure-resistant cabin is cylindrical.

[0005] There is almost no research on ocean depth-fixed hovering neutral buoys in the prior art, and profiling buoys are all spherical or cylindrical. As a neutral buoy for Lagrangian depth-fixed hovering ocean observation of the middle and upper layers of the ocean, it should have the ability to rise and fall regularly and the ability to communicate when rising to the sea surface. It should also meet the safety and concealment of the entire observation system and the attitude stability during depth-fixed hovering observation, make up for the lack of depth-fixed observation capabilities of profiling buoys for the middle and upper layers, and meet the needs of the control system, power guarantee system and even other observation equipment for direct storage of the mother buoy and the need for rapid lifting from the sea surface to a specific water depth. The sea surface drifting buoys in the prior art can only realize continuous observation of the sea surface, and are all spherical in shape; while the profile buoys in the prior art are selected to be spherical or cylindrical in shape. On the one hand, due to the influence of the appearance, the speed of its lifting and lowering is slow, the time consumption is long, and the energy consumption is high; in addition, since the buoy is subject to large water resistance and is greatly affected by wind and waves on the sea surface, it is difficult to achieve automatic attitude correction when it conducts regular communication on the sea surface, and the communication efficiency is low and the power consumption is large; when a neutral buoy of this shape is used for depth hovering, its turbulence resistance is weak, the motion stability is insufficient, and the depth hovering capability cannot meet the needs of platform stability for observation. Utility Model Content

[0006] The main purpose of the utility model is to provide a spindle-shaped neutral buoy suitable for fixed-depth hovering observation in the middle and upper oceans, and to improve its appearance so that it has beautiful appearance, dynamic balance, stable structure, rapid lifting and lowering, strong turbulence resistance, good movement stability, high carrying capacity, small resistance in water, and weak influence of wind and waves on the sea surface, thereby improving ocean observation and communication capabilities.

[0009] Compared with the spherical or cylindrical shape, its shuttle-shaped shape is beautiful in appearance, dynamically balanced, and stable in structure, which improves the speed of ascent and descent, reduces the time consumption, and consumes less energy. At the same time, it is subject to less water resistance and is less affected by wind and waves on the sea surface, which can improve ocean observation and communication capabilities. When hovering, it has strong turbulence resistance, good motion stability, and meets the needs of platform stability for conducting observations.

It is a buoy necessary for Lagrangian ocean observation / monitoring in the middle and upper ocean, especially for Lagrangian ocean observation / monitoring in the middle and upper ocean using timed communication.

[0029] Its longitudinal section is formed by arcs with radii proportional to each other in the series 5 and 21; specifically, with its upper and lower symmetry axes and left and right symmetry axes as center points, a first circle with a radius of 5 units is drawn; with the points 16 units to the left and right of the center point on the upper and lower symmetry axes as center points, a second circle and a third circle with a radius of 21 units are drawn respectively, the second circle and the third circle are inscribed in the first circle respectively, and the second circle and the third circle have an intersection point on both sides of the upper and lower symmetry axes respectively; the arc part of the second circle and the third circle between the two intersection points is a shuttle shape; the arc part on the left and right sides of the second circle and the third circle between the two intersection points is the left side 1 of the shuttle shape and the right side 2 of the shuttle shape.

[0030] The surface of this spindle-shaped neutral buoy suitable for fixed-depth hovering observation in the middle and upper oceans is divided into three parts, namely, a spindle-shaped upper part 3, a spindle-shaped middle part 4 and a spindle-shaped lower part 5 at 1 / 5 and 4 / 5 heights from top to bottom, and is painted in light blue, blue and dark blue from top to bottom.

[0031] The hydrological observation module 6 , the positioning communication module 7 and the satellite communication antenna module 8 are arranged in the shuttle-shaped upper part 3 , the data storage module 9 , the balancing module 10 and the control module 11 are arranged in the shuttle-shaped middle part 4 , and the battery 12 is arranged in the shuttle-shaped lower part 5 .
