Description

Technical Field

[0001] This utility model relates to the field of buoy technology, and in particular to a buoy that reduces rolling. Background Technology

[0002] In fields such as marine science research, climate prediction, and marine environmental monitoring, accurate observation of air-sea fluxes (including momentum flux, heat flux, and mass flux) is a core foundation. By acquiring data on energy and mass exchange between the air-sea interface, we can provide crucial support for understanding ocean circulation, global climate change mechanisms, and the formation processes of extreme weather events such as typhoons.

[0003] Traditional buoys often employ single- or double-compartment buoyancy structures with poorly designed centers of gravity, making them prone to violent swaying or tilting under the influence of wind, waves, and ocean currents. These attitude changes directly interfere with the measurement accuracy of sensors for wind speed, direction, radiation, temperature, and humidity, leading to significant errors in air-sea flux calculations. Especially under extreme sea conditions such as typhoons and giant waves, they can even cause equipment damage due to loss of attitude control. Furthermore, traditional mooring systems often use single steel cables or simple combinations of ropes, which are structurally rigid but have weak buffering capacity. Under the influence of strong currents and giant waves in the deep sea, they are susceptible to concentrated stress, leading to cable breakage or anchoring failure. Summary of the Invention

[0004] To address the shortcomings of the existing technologies, a roll-damping buoy is provided, which improves the stability of the buoy under extreme sea conditions, thereby enhancing the accuracy of data observation.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is a roll-damping buoy, comprising a main float consisting of five buoyancy chambers, connecting rods at the top of the five buoyancy chambers, and floats at the bottom of the five buoyancy chambers. A sealed chamber connected to the main float via a first inclined rod is located in the middle of the main float. A control chamber connected to the main float via a second inclined rod is located at the top of the sealed chamber. An upper mast is located at the top of the control chamber, and a first support rod is located at the top of the upper mast. A buoy platform attitude monitoring system is located on the first support rod. A lower mast is located at the bottom of the sealed chamber, and an instrument compartment and a battery compartment are located at the bottom of the lower mast. An anchoring mechanism is connected to the bottom of the battery compartment. Connecting rods are provided between adjacent floats. An oil cavity is located inside each float, and the oil cavity is filled with damping oil.

[0006] The aforementioned anti-roll buoy has a buoy outer wall wrapped with a damping material layer, which is made of polyurethane foam or rubber-based composite material.

[0007] In the aforementioned type of anti-roll buoy, the thickness of the damping material layer is 5-10mm, and the surface is provided with grooves or textured structures.

[0008] The aforementioned anti-roll buoy further includes a pipeline pump and valve system for controlling the flow of damping oil, the pipeline pump and valve system including an electric hydraulic pump and a solenoid valve assembly; the connecting rod is provided with a through cavity for connecting the oil chambers of each float to form a closed hydraulic circuit; the electric hydraulic pump and the solenoid valve assembly are mounted on the connecting rod, and the electric hydraulic pump and the solenoid valve assembly are signal-connected to the controller.

[0009] The aforementioned anti-roll buoy, wherein the buoy platform attitude monitoring system includes: The gas analyzer installed on the first support pole, along with the GPS, gyroscope, electronic compass, and accelerometer adjacent to the gas analyzer, also includes a first air temperature and humidity sensor, a sea surface temperature sensor, a four-component radiation sensor, and an atmospheric pressure sensor. The four-component radiation sensor extends horizontally 2 meters beyond the first support pole, and the highest point of the first support pole is 6 meters above the average water level.

[0010] The aforementioned anti-roll buoy has a second support rod below the first support rod, and a second air temperature and humidity sensor and a wind speed and direction sensor are installed on the second support rod; the highest point of the second support rod is 3 meters above the average water level, and a marine droplet flux meter is installed above the control cabin, the marine droplet flux meter being 1.5 meters above the average water level.

[0011] The aforementioned type of anti-roll buoy is equipped with a single-point current meter and a wave meter on the water surface, which are connected to the main buoy via a Dyneema rope.

[0012] The aforementioned anti-roll buoy, wherein the mooring mechanism comprises a main cable, a relay transmission chamber, and an anchoring unit, the mooring mechanism having an overall inverted S-shaped structure, the length of which is 1.3-1.5 times the water depth of the deployment area, and the anchoring unit comprising a gravity anchor, a holding anchor, and an anchor chain.

[0013] The aforementioned anti-roll buoy has a main cable consisting of a coupling steel cable and a Dyneema cable. The coupling steel cable consists of two sections, each 500m long, with a relay transmission compartment between the two sections. The Dyneema cable has a diameter of 15mm and its surface is coated with an anti-corrosion coating. The coupling steel cable, the Dyneema cable, and the parallel release device are connected by a waterproof connector.

[0014] The aforementioned anti-roll buoy has glass floats spaced 50-100m apart on the main cable, and a counterweight on the main cable; an electric rotating ring is provided between the top of the main cable and the bottom of the battery compartment, and a parallel release device is provided between the bottom of the main cable and the anchoring unit.

[0015] The beneficial effect of this utility model of a roll-damping buoy is that the main buoy adopts a combination structure of "five buoyancy chambers, top connecting rod and bottom buoy", and with the center of gravity design of "battery compartment located at the bottom of the lower mast", the center of gravity of the buoy is greatly reduced, effectively suppressing the swaying and tilting under the action of wind and waves.

[0016] Because the upper and lower masts are slender columns with small cross-sections, wind and water resistance can be greatly reduced while minimizing wave interference, thus further improving the stability of the buoy in extreme sea conditions.

[0017] The relaxed inverted S-shaped structure can absorb external impacts through its own shape changes, reducing the sway amplitude of the air-sea flux buoy and improving the accuracy of data observation.

[0018] Through its segmented design and integration with the relay transmission cabin, the coupling steel cable can adapt to the complex environment of the deep sea, ensuring stable and reliable data and power transmission over long distances. It breaks through the limitations of single-cable transmission distance and is suitable for deep-sea environments above 4,000 meters. Attached Figure Description

[0021] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. Example

[0022] like Figure 1-4 As shown, an air-sea flux buoy includes a main float consisting of five buoyancy chambers 1, connecting rods 2 at the top of the five buoyancy chambers 1, and floats 3 at the bottom of the five buoyancy chambers 1. A sealed chamber 5 connected to the main float via a first inclined rod 4 is located in the middle of the main float. A control chamber 7 connected to the main float via a second inclined rod 6 is located at the top of the sealed chamber 5. An upper mast 8 is located at the top of the control chamber 7, and a first support rod 9 is located at the top of the upper mast 8. A buoy platform attitude monitoring system is mounted on the first support rod 9. A lower mast 10 is located at the bottom of the sealed chambers 5. An instrument compartment 11 and a battery compartment 12 are located at the bottom of the lower mast 10. The battery portion of the entire system is designed to be installed at the bottom of the lower mast, breaking through the conventional center of gravity position of buoy platforms, greatly increasing the buoy's stability and improving its wave resistance. An anchoring mechanism is connected to the bottom of the battery compartment 12. The air-sea flux buoy is divided into an above-water section and an underwater section. The overall length of the air-sea flux buoy is approximately 13.75 meters, and the above-water section is approximately 6 meters long. A solar panel 35 is installed above the main buoy. A CTD24 is installed below the sealed compartment 5. The upper mast 8 and lower mast 10 are made of five titanium alloy round tubes of equal length combined with molded polyurea material, reinforced with an internal titanium alloy round tube skeleton and filled with elastic non-absorbent foam material. Because the upper mast 8 and lower mast 10 are slender columns with a small cross-section, wind and water resistance can be greatly reduced while minimizing wave interference, significantly improving the buoy's ability to control the sway amplitude. A connecting rod 39 is provided between adjacent floats 3, and an oil chamber 40 is provided inside the float 3, which is filled with damping oil.

[0023] The buoy 3 is made of a high-strength, seawater-corrosion-resistant metal alloy (such as titanium alloy) and has a fully sealed structure to prevent seawater from seeping into the internal oil cavity. The damping oil is a high-viscosity damping oil (such as silicone oil). The damping oil consumes the energy generated by wave impact through its own viscous resistance, achieving passive roll reduction, while the buoyancy of the oil cavity helps the buoy maintain overall balance.

[0024] When waves impact the buoy, the damping oil inside the float 3 generates shear resistance due to its viscosity, hindering the rapid swing of the float 3; at the same time, the external damping material consumes wave energy through deformation and friction, weakening the impact load.

[0025] The buoy platform attitude monitoring system includes: The gas analyzer 36 installed on the first support rod 9, as well as the GPS, gyroscope, electronic compass 13, and accelerometer adjacent to the gas analyzer 36, also includes a first air temperature and humidity sensor 14, a sea surface temperature sensor 15, a four-component radiation sensor 16, and an atmospheric pressure sensor. The four-component radiation sensor 16 extends horizontally 2 meters beyond the first support rod, and the highest point of the first support rod 9 is 6 meters above the average water level.

[0026] The gas analyzer 36 (CPEC310 including a three-dimensional ultrasonic anemometer (CSAT3BH)), the four-component radiation sensor 16 (CNR4+CNF4), the sea surface temperature sensor 15 (SI-111), the GPS 37, the gyroscope 38, the first air temperature and humidity sensor 14 (HMP155), and the atmospheric pressure sensor (PTB110) are placed 6 meters above the average water level. The reasons are as follows: 1. The four-component radiation sensor 16 (CNR4+CNF4) is placed at a distance of 6 meters to avoid the influence of shadows cast by the sun on the buoy on the data, in accordance with the national standard (GB / T 12763.3-2020) for marine surveys. The sensor must not be obstructed during solar radiation observation. Simultaneously, the four-component radiation sensor 16 (CNR4+CNF4) should extend horizontally by 2 meters, with its downward-facing radiation sensor having a field of view of 150°. Calculations have shown that this avoids the influence of air-sea flux buoy reflections on radiation measurements.

[0027] 2. According to the national standard (GB / T 12763.3-2020) for marine surveys, the effective observation height for sea surface temperature is 0-10 meters. When monitoring sea surface temperature, the field of view of the sensor itself should be considered. The field of view of the sea surface temperature sensor (SI-111) is 22° (half angle). After calculation, the 6-meter distance meets the requirements of the standard while maximizing the performance of the instrument itself.

[0028] 3. To ensure the consistency of the sensor's trajectory with the air-sea flux buoy, GPS 28 and gyroscope 29 should be placed at the same height as the gas analyzer 36 and as close as possible for correction of air-sea flux data. This will improve the accuracy and precision of flux data calculation.

[0029] 4. The air vapor flux meter is installed at the top of the upper mast 8. Based on the flux contribution area (footprint) formula (Schueppat el. 1990; Leclerc and Thurtell 1990), its effective flux data contribution area radius is 100 times the installation height. In marine systems with relatively uniform buoy surfaces, installing the air vapor flux meter at the top of the upper mast 8 maximizes the acquisition of flux data from the contribution area. Simultaneously, installation at the top minimizes the cutting and breaking effects of the upper mast 8 on the airflow, improving instrument measurement accuracy.

[0030] A second support rod 17 is provided below the first support rod 9. A second air temperature and humidity sensor 18 and a wind speed and direction sensor 19 are installed on the second support rod 17. The highest point of the second support rod 17 is 3 meters above the average water level. A marine droplet flux meter 20 is provided above the control cabin 7. The marine droplet flux meter 20 is 1.5 meters above the average water level.

[0031] The impact of boundary layer turbulence on ocean droplet transport is negatively correlated with the distance of the equipment from the sea surface. Considering that the higher the installation height, the lower the impact, and that the stability of the equipment's fixed position is closely related to data quality, all factors are taken into account. Observations at 1.5 meters provide high data quality and good equipment stability, reducing the impact of buoy swaying on the data.

[0032] A single-point current meter 21 and a wave meter 22 are installed on the water surface and connected to the main buoy via a Dyneema rope. The single-point current meter 21 is a current sensor (5400), and the wave meter 22 is a wave sensor (DWR-G), placed on the water surface and floating. Simultaneously, they are connected to the sealed chamber 5 via the Dyneema rope, allowing it to float relatively freely on the water surface while also being secured to the air-sea flux buoy. The reason is as follows: 1. The ocean current sensor (5400) uses the Doppler principle and needs to be in contact with the water surface to operate. It must also be protected from interference from the underwater structure of the air-sea flux buoy, therefore a dyneema line is required to connect it to the buoy body, allowing it to drift relatively freely. It can also obtain power and data transmission from the buoy system.

[0033] 2. The wind force around the air-sea flux buoy is affected by the buoy's structure, and its impact on ocean waves differs significantly from that of natural ocean waves. The wave sensor (DWR-G) with its built-in accelerometer measures ocean waves and needs to be in contact with the water surface and float. Therefore, it needs to be connected to the buoy body with a dyneema line to allow it to drift relatively freely. It can also obtain power and data transmission from the buoy system.

[0034] The mooring mechanism comprises a main cable, a relay transmission compartment 23, and an anchoring unit. The overall mooring mechanism has an inverted S-shaped structure, with a length 1.3-1.5 times the water depth of the deployment area. This makes the inverted S-shaped structure a relaxed inverted S-shaped structure.

[0035] The main cable consists of a coupling steel cable 25 and a Dyneema cable 26. The coupling steel cable 25 comprises two sections, each 500m long, with a relay transmission compartment 23 located between the two sections. The Dyneema cable 26 has a diameter of 15mm and an anti-corrosion coating. The Dyneema cable 26 is characterized by high strength and low weight, capable of withstanding the impact of waves and currents. The Dyneema material is resistant to seawater corrosion and UV aging, allowing for long-term stable operation in deep-sea environments. Combined with the anti-corrosion coating, its service life is further extended, meeting the needs of long-term (typically over one year) fixed-point observations by the air-sea flux buoy. The inverted S-shaped relaxation structure effectively buffers the impact of waves and currents on the buoy, reducing the stress on the system under extreme sea conditions and improving the stability of the air-sea flux buoy in extreme environments such as typhoons and large waves. The relaxed inverted S-shaped structure absorbs external impacts through its own shape changes, reducing the sway amplitude of the air-sea flux buoy and improving the accuracy of data observations.

[0036] As the transmission carrier for underwater signals and power, the coupling steel cable 25 stably transmits power supply and data signals between various components of the buoy system, ensuring effective communication between underwater sensors, relay transmission cabin 3, and other equipment with the buoy's data acquisition system. The coupling steel cable 25 consists of two sections, each 500m long, with a relay transmission cabin 23 located between the two sections. The relay transmission cabin 23 relays the data to the control cabin 7, and then transmits it to the shore station via satellite. Through its segmented design and the coordination of the relay transmission cabin, it can adapt to the complex environment of the deep sea, ensuring stable and reliable data and power transmission over long distances, breaking through the limitations of single-cable transmission distance, and is suitable for deep-sea environments above 4000 meters.

[0037] The main cable is equipped with 28 glass buoys spaced 50-100m apart. These buoys balance the weight of the main cable and underwater equipment through buoyancy, preventing the main cable from sag excessively and causing entanglement or breakage. Up to 12 glass buoys can be used to ensure the buoyancy balance of the buoy observation system in the lower layers of the water.

[0038] The main cable is equipped with a counterweight 29, which is made of titanium alloy. By setting the counterweight 29, the swaying of the main cable under the action of water flow is reduced, thereby reducing interference with underwater sensors and other equipment. In conjunction with the glass float 28, the overall anchoring system has an inverted S-shaped structure.

[0039] The top of the main cable is connected to the bottom of the battery compartment 12 via an electric rotating ring 30. The main function of the electric rotating ring 30 is to ensure stable transmission of power and data signals between the main cable and the air-sea flux buoy when the buoy rotates with the waves, etc., and to avoid the main cable from getting tangled or twisted due to the rotation of the air-sea flux buoy, which would affect the continuity and reliability of power supply and data transmission.

[0040] A parallel release device 31 is installed between the bottom of the main cable and the anchoring unit. Since the air-sea flux buoy is deployed in a deep-sea environment, after long-term observation, it is necessary to retrieve the equipment, replace parts, or obtain stored data. The parallel release device 31 allows for convenient separation of the air-sea flux buoy from the anchoring unit, avoiding equipment loss or difficulty in retrieval due to the anchoring unit being unable to detach. Simultaneously, in the event of extreme sea conditions that may endanger the safety of the air-sea flux buoy, the parallel release device 31 can serve as an emergency protection device, ensuring that the core observation equipment can be retrieved and minimizing losses. Two parallel release devices 7 are used.

[0041] The anchoring unit includes a gravity anchor 32, a holding anchor 33, and an anchor chain 34. Compared to a single gravity anchor 32, this increases the air-sea flux buoy's resistance to wind, waves, and currents, thereby improving its stability in the marine environment. The holding anchor 33 weighs approximately 6 tons, and the anchor chain 34 consists of 4 sections.

[0042] The coupling steel cable 25, Dyneema cable 26, and parallel release device 31 are connected by a waterproof connector 27. The waterproof connector 27 can effectively block seawater and prevent it from seeping into the connection of the main cable or equipment, ensuring the continuity of power transmission and data signal transmission, and avoiding equipment failure due to water ingress. Example

[0043] The parts that are the same as in Example 1 will not be repeated here. The difference is that: Figure 5As shown, the outer wall of the pontoon 3 is wrapped with a damping material layer 41, which is made of polyurethane foam or rubber-based composite material. The damping material layer 41 has a thickness of 5-10 mm and a grooved or textured structure on its surface. The damping material is uniformly wrapped on the outer wall of the pontoon 3 using molding or bonding processes to form the damping material layer. The surface of the damping material layer is designed with grooves or textured structures, such as honeycomb or striped grooves, to increase the frictional resistance with seawater and absorb the kinetic energy of waves through the deformation of the material itself. Example

[0044] The similarities between this embodiment and Embodiment 1 will not be repeated here. The difference lies in that: to address the dynamic adjustment requirements under different wind and wave conditions, such as... Figure 6 As shown, it also includes a pipeline pump-valve system for controlling the flow of damping oil. The pipeline pump-valve system includes an electric hydraulic pump 42 and a solenoid valve assembly 43. The connecting rod 39 has a through cavity for connecting the oil chambers of each float 3 to form a closed hydraulic circuit. The electric hydraulic pump and solenoid valve assembly are mounted on the connecting rod 39, and the electric hydraulic pump 42 and solenoid valve assembly 43 are signal-connected to the controller. The controller is a microcontroller unit (MCU) or a single-chip microcomputer.

[0045] The connecting rods can be made of corrosion-resistant metal pipes, connecting the oil chambers 40 inside the floats 3 to form a closed hydraulic circuit. An electric hydraulic pump 42 is installed on the metal pipes to drive the flow of damping oil between the floats 3. A solenoid valve assembly is installed at the junction of the connecting rods, controlled by signals from the buoy platform attitude monitoring system (gyroscope, accelerometer). This assembly controls the transfer of damping oil between different floats through the pump valves, precisely adjusting the flow direction and flow rate of the damping oil, adjusting the buoy's center of gravity distribution, and actively counteracting the capsizing moment generated by wind and waves.

[0046] The attitude monitoring system (gyroscope, accelerometer) captures the buoy's roll and pitch angles (accuracy ≤0.1°) and oscillation frequency in real time. The attitude monitoring system (gyroscope, accelerometer) is electrically connected to the buoy's control unit. The control unit determines the direction of the buoy's force imbalance under the current wind and wave conditions based on the preset wind and wave load-buoyancy matching model. It then controls the operation of the drive electric hydraulic pump and solenoid valve group to transfer damping oil from the "force-bearing side float" to the "balance side float", changing the buoy's center of gravity position and generating a reverse torque to counteract the impact of wind and waves, thus achieving dynamic stability control.

[0047] By combining the "passive damping" in Example 1 with the "active adjustment" in this example, the impact of conventional waves can be weakened by using silicone oil and damping materials, and the buoy's center of gravity can be dynamically adjusted for extreme sea conditions, effectively controlling the buoy's sway amplitude and improving the accuracy of sensor observation data.

[0048] During installation, electric hydraulic pumps and solenoid valve assemblies suitable for the marine environment should be selected, and products with high protection levels, such as models that meet IP65 and above standards, should be given priority, as they can effectively resist the invasion of seawater droplets and rainwater.

[0049] The sealing of the junction box for the electric hydraulic pump and solenoid valve assembly is crucial. The sealing gasket on the junction box cover must be intact. Tighten the screws evenly during installation to prevent gaps. If the gasket ages, replace it with a weather-resistant gasket of the same specification. Use waterproof glands at the cable inlet, selecting the appropriate gland size based on the cable diameter. When tightening, ensure the rubber sealing ring tightly wraps around the cable to prevent seawater from entering through cable gaps. Strict sealing treatment is required for the connection points between the electric hydraulic pump and solenoid valve assembly, as well as their connections to pipelines. For threaded connections, wrap Teflon tape around the threads and apply sealant, such as Loctite 596 sealant, ensuring there is no looseness after tightening.

[0050] Alternatively, protective enclosures can be installed for the electric hydraulic pump and solenoid valve assembly. These enclosures should be made of stainless steel or engineering plastics, offering excellent corrosion resistance. Drainage holes should be pre-drilled at the bottom of the enclosure to prevent rainwater or seawater from accumulating inside.

[0051] Of course, the above description is not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
