Description

Technical Field

[0001] The utility model belongs to the field of ocean observation, and in particular relates to a floating ball used for a submerged buoy. Background Art

[0002] In the fields of marine scientific research, resource exploration and environmental monitoring, as the latest development of the most important observation platform for long-term anchored safety observation / monitoring of the marine environment, the high-quality observation and safe communication of the timed communication anchored buoy observation system requires the joint action of the communication buoy of timed communication and the main buoy for large-profile current observation. In marine observation, the Euler method is a major form of marine observation. Anchored buoys, anchored buoys and seabed bases are the three most commonly used Euler method observation platforms, which are mainly suitable for the observation of marine parameters at fixed positions. Compared with anchored buoys, although anchored buoys have the disadvantage of weak communication capability, they have the advantages of long-term concealment, easy deployment and not easy to be destroyed. In recent years, the newly developed timed communication anchored buoys take into account some of the advantages of anchored buoys and anchored buoys, solve the communication capability problem of anchored buoys, and have higher reliability and security in terms of timed communication.

[0003] For example, the invention patent with publication number CN104890816B discloses a timing satellite communication buoy, including a vertically arranged plastic-coated steel cable, on which are arranged a first inductively coupled temperature and salt chain, a second inductively coupled temperature and salt chain, a main buoy, and a deep-sea current and temperature and salt measurement unit; the main buoy is equipped with an acoustic Doppler current profiler, a satellite communication buoy, a timing release device and a data and control electronic warehouse; the buoy measuring instruments are connected to the data and control electronic warehouse through cables, respectively.

[0004] The buoys in the prior art are mostly submarine-shaped, cylindrical or spherical. Due to the design defects of the outer wall, the outer shape is subjected to uneven force, the posture is not stable enough in the water, and it is inconvenient to deploy and recover. It is easy to roll over during storage and transportation, and its unreasonable outer shape design also causes greater resistance from the water during recovery and deployment.

[0005] In view of this, this application is hereby filed. Utility Model Content

[0006] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a floating ball for a submerged buoy. The utility model is achieved through the following technical solutions:

[0007] A floating ball for a submerged buoy comprises a shell, wherein the longitudinal sections of the shell in all directions are axially symmetrical quasi-circular sections, the quasi-circular sections are formed by combining a plurality of tangent arcs, and the diameters of the arcs on both sides of the longitudinal direction at the maximum diameter position of the quasi-circular section gradually decrease to form a smooth outer wall of the shell.

[0008] Preferably, an equipment compartment is provided in the housing.

[0009] Preferably, the equipment compartment is arranged along the central axis of the shell as a hollow channel with openings at both ends.

[0010] Preferably, an upward-looking Doppler current profiler and a downward-looking Doppler current profiler are respectively installed at the upper and lower ends of the hollow channel, and a control module and a power supply module are arranged between the upward-looking Doppler current profiler and the downward-looking Doppler current profiler.

[0011] Preferably, a plurality of buoy nests opening upward are provided on the shell.

[0012] Preferably, the buoy nests are distributed in a circular array along the central axis of the shell.

[0013] Preferably, a waterproof coating is coated on the outer wall of the shell.

[0014] Preferably, the shell is an apple-shaped structure with a large upper portion and a small lower portion.

[0015] Preferably, the float is filled with glass beads and resin.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. By setting the shell to a quasi-circular cross-section, the float is ensured to have good stability in the water, reducing the rotation and shaking caused by hydrodynamics, thereby improving the accuracy of the measurement data. In addition, the smooth outer wall of the shell can reduce water flow resistance and improve the underwater movement efficiency of the float.

[0018] 2. By setting the equipment compartment as a hollow channel with openings at both ends along the central axis of the shell, it is convenient for wiring and maintenance of the equipment, and it is also more suitable to install an upward-looking Doppler current profiler and a downward-looking Doppler current profiler at both ends of the hollow channel respectively.

[0019] 3. By setting a waterproof coating on the outer wall of the shell, it can prevent seawater erosion, extend the service life of the float, keep the surface of the shell smooth, effectively reduce water film adhesion, and further reduce underwater resistance. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The utility model is further described below in conjunction with the accompanying drawings.

[0023] like Figure 1 As shown, this embodiment provides a buoy for a submerged buoy, including a shell 1, the longitudinal sections of the shell 1 in all directions are axially symmetrical quasi-circular sections, the quasi-circular sections are formed by a combination of multiple tangent arcs, and the diameters of the arcs on both sides of the longitudinal direction at the maximum diameter position of the quasi-circular section gradually decrease to form a smooth outer wall of the shell 1.

[0024] By setting the shell 1 to a quasi-circular cross section, the float is ensured to have good stability in the water, reducing the rotation and shaking caused by hydrodynamics, thereby improving the accuracy of the measurement data. In addition, the smooth outer wall of the shell 1 can reduce water flow resistance and improve the underwater movement efficiency of the float.

[0025] Preferably, the housing 1 is an apple-shaped structure with a large upper portion and a small lower portion, which helps the float to maintain a vertical state in the water. The apple-shaped structure with a large upper portion and a small lower portion can provide better buoyancy distribution, ensuring that the float maintains a specific posture stably on the water surface, and helps the float to self-position and orient in the ocean current.

[0026] During transportation, the buoy is often placed on the deck. The apple-shaped placement effect is better than the spherical shape and other easy-to-roll shapes. The apple-shaped bottom support is also conducive to stable placement during transportation.

[0027] Under the condition of a certain volume, compared with buoys of other shapes, the solution provided in this embodiment can to a large extent reduce the water resistance of the buoy when it is deployed and sinks, and when it is recovered and floats, shorten the time consumed in sinking and floating, and can automatically right its posture to achieve rapid deployment and rapid recovery of the anchored submerged buoy; it can help the anchored submerged buoy to maintain a stable posture in the water flow and reduce the impact of fluid disturbances; it has higher stability than buoys of other shapes, can resist the effects of external forces, and is not easy to capsize or be damaged during transportation and storage.

[0028] The specific design method of the longitudinal section of the shell is to connect the arcs with proportional radii of the series 1, 3, 5, 8, 13, and 26. Based on the central axis of the float, three circles A, B, and C are drawn from bottom to top with radii of 8 units, 13 units, and 13 units respectively. Circle A is circumscribed with circle B, and circle B is circumscribed with circle C. The three centers and two circumscribed points are all located on the central axis.

[0029] Draw three circles D1, E, and D2 above circle A, with radii of 5 units, 1 unit, and 5 units respectively. The centers of circles D1, E, and D2 are on the same horizontal line. Circles D1 and D2 are circumscribed to circle A respectively, and the arc between the two circumscribed points is the bottom of the float. With the centers of circles D1 and D2 as vertices and the line connecting the centers of circles D1 and D2 as the base, draw a line segment of 8 units in length to the upper left and upper right at an angle of 135 degrees; draw circles with radii of 3 units at the other end points of the two line segments: circle F1 and circle F2.

[0030] On the left side of the central axis, draw a circle with a radius of 8 units and circumscribed to the central axis and circle F1: circle G1. On the right side of the central axis, draw a circle with a radius of 8 units and circumscribed to the central axis and circle F2: circle G2. At this time, circle G1 and circle G2 are circumscribed to circle C at the same time, and the arc between the two circumscribed points is the top of the apple float.

[0031] With a radius of 26 units, make the circumscribed circle H1 of circle F1 and circle G1, and the circumscribed circle H2 of circle F2 and circle G2 respectively; the arc portion between the tangent point of the circumscribed circle H1 and circle G1 and the tangent point of circle G1 and circle C is the left portion of the upper shoulder; the arc portion between the tangent point of H2 and circle G2 and the tangent point of circle G2 and circle C is the right portion of the upper shoulder; the arc portion between the tangent point of the circumscribed circle H1 and circle D1 and the tangent point of circle D1 and circle A is the left portion of the upper shoulder; the arc portion between the tangent point of H2 and circle D2 and the tangent point of circle D2 and circle A is the right portion of the lower shoulder; the arc portion between the tangent point of the circumscribed circle H1 and circle D1 and the tangent point of the circumscribed circle H1 and circle G1 is the left connecting portion between the upper and lower shoulders; the arc portion between the tangent point of the circumscribed circle H2 and circle D2 and the tangent point of the circumscribed circle H2 and circle G2 is the right connecting portion between the upper and lower shoulders.

[0032] The housing 1 is provided with a device compartment 2. The device compartment 2 is provided along the central axis of the housing 1 as a hollow passage 21 with openings at both ends.

[0033] Preferably, an upward-looking Doppler current profiler 22 and a downward-looking Doppler current profiler 23 are respectively installed at the upper and lower ends of the hollow channel 21, and a control module 24 and an energy supply module 25 are arranged between the upward-looking Doppler current profiler 22 and the downward-looking Doppler current profiler 23. By configuring the equipment compartment 2 as a hollow channel 21 with openings at both ends along the central axis of the shell 1, it is convenient for wiring and maintenance of the equipment, and it is also more suitable to install the upward-looking Doppler current profiler 22 and the downward-looking Doppler current profiler 23 at both ends of the hollow channel 21.

[0034] Specifically, the energy supply module 25 is an electrical component such as a battery, and the control module 24 is a microprocessor and corresponding components for processing monitoring information.

[0035] Preferably, a plurality of buoy nests 3 opening upward are provided on the shell 1. Further, the buoy nests 3 are distributed in a circular array along the central axis of the shell 1. The circular array distribution along the central axis and reasonable distribution and layout can carry more communication buoys 4, which are used for regular over-sea deployment and sending out the stored detection information. Therefore, more communication buoys 4 can obtain more deployment opportunities, which can also extend the working time of the submerged buoy in the sea.

[0036] The outer wall of the shell 1 is coated with a waterproof coating. By providing the waterproof coating on the outer wall of the shell 1, seawater erosion can be prevented, the service life of the float can be extended, and the surface of the shell 1 can be kept smooth. In addition, water film is easily formed in seawater, and the water film hinders the penetration of electromagnetic waves. The waterproof coating can also effectively reduce the adhesion of the water film and further reduce the underwater resistance.

[0037] Preferably, a hook for connecting cables and other components is provided at the bottom of the housing 1 .

[0038] Furthermore, a timing release device (not shown in the figure) is provided in the buoy nest 3, and the measurement data of the timing communication is transmitted to the communication buoy 4 by means of cable-free magnetic induction wireless communication and the like; after completing the observation of the predetermined time period, the communication buoy 4 is released by the timing release device at the predetermined time, and the release time interval is usually set to 1 month. (Underwater magnetic induction communication is a technology that uses magnetic field as a carrier to transmit information, and has the advantages of strong concealment and high transmission rate. It is an existing technology and will not be described in detail here.)

[0039] The float is filled with glass beads and resin. The float uses a composite material of glass beads and resin as a filler, and the shell 1 uses glass fiber reinforced plastic (FRP). Glass beads are lightweight, high-strength, corrosion-resistant particles that increase buoyancy and reduce weight in the composite material. The resin acts as a binder to tightly bind the glass beads together to form a composite structure with excellent mechanical properties and chemical stability.

[0040] FRP has a very high strength-to-weight ratio, which means that even in extreme marine environments, the float can maintain structural integrity and withstand long-term corrosion, wear and impact. At the same time, due to the dielectric properties of glass beads and resin, the float material absorbs and reflects less electromagnetic waves, which is beneficial to the signal transmission of wireless communication equipment and radar sensors carried, and improves the reliability and accuracy of data communication.
