Description

Technical Field

[0001] This invention relates to the field of marine buoys, specifically to a seawater self-ballast split-type buoy. Background Technology

[0002] In marine-related fields such as ocean monitoring, navigational marking, and environmental detection, buoys are widely used as key equipment. They need to operate stably for extended periods under complex and changing sea conditions to ensure the normal functioning of data acquisition and signal transmission. However, current buoy products on the market still have many unresolved issues in structural design and performance, making it difficult to meet the high-efficiency and stable requirements of practical applications. To achieve the designed stability of the buoy, its center of gravity needs to be lowered, and the buoy needs to reach its designed draft, which requires adding extra ballast. In existing technologies, high-density materials such as cement or ballast iron are generally used as ballast, and the weight of these extra ballast materials is a significant factor contributing to the increased costs of buoy construction, transportation, and maintenance.

[0003] Patent CN214356541U discloses a seawater self-ballast buoy. By setting up a ballast water tank on the buoy body, seawater naturally enters the tank to provide ballast, eliminating the need for additional ballast materials such as cement and ballast iron. This effectively reduces the overall weight of the buoy during deployment and retrieval, lowers the construction, operation and maintenance costs of the buoy, and reduces the equipment requirements for vessels operating at sea. It also improves the safety of offshore operations to a certain extent and provides a new approach to lightweight buoy design.

[0004] Although the above-mentioned scheme provides ballast by introducing seawater into the ballast tanks without the need for additional ballast, its stability in complex marine environments remains significantly flawed. In the marine environment, ocean currents and waves are common occurrences, and such external forces can easily cause the buoy to tilt and sway. When the buoy tilts, the ballast tank on the downward tilting side will receive more seawater due to the increased depth, while the ballast tank on the upward tilting side will lose some seawater due to the drop in water level. This phenomenon will cause a sharp increase in the buoy's center of gravity shift, further exacerbating the buoy's tilt. If the tilt angle exceeds the safety threshold, it will not only affect the normal operating accuracy of the monitoring equipment on the buoy, but may also cause the buoy to capsize due to imbalance, seriously threatening the buoy's structural safety and operational stability, and failing to meet the requirements for long-term reliable operation in complex sea conditions. Summary of the Invention

[0005] To address the aforementioned issues, a self-ballasting split-type seawater buoy is provided. By incorporating an anti-tipping structure, the tilting and swaying of the buoy body is effectively suppressed, ensuring that the buoy body can function normally under complex sea conditions.

[0006] To address the problems of existing technologies, this invention provides a seawater self-ballasting split-type buoy, comprising a buoy body and an anti-tipping structure. The buoy body includes multiple ballast water tanks arranged around its central axis.

The anti-tipping structure includes a mounting base and multiple buoyancy self-adjusting structures. The mounting base is located in the middle of the multiple ballast water tanks. Each buoyancy self-adjusting structure corresponds to one of the multiple ballast water tanks. Each buoyancy self-adjusting structure includes a support arm assembly, an elastic reset assembly, a float assembly, and an air supply assembly. One end of the support arm assembly is hinged to the mounting base. The two ends of the elastic reset assembly are hinged to the upper end of the ballast water tank and the middle of the support arm assembly, respectively. The elastic reset assembly provides a pulling force towards the ballast water tank to the support arm assembly. The float assembly is connected to the other end of the support arm assembly.

[0008] Preferably, the pontoon assembly includes an upper limit plate and a pontoon airbag; the upper limit plate is connected to the end of the second support arm; the pontoon airbag is located at the lower end of the upper limit plate and is connected to the ballast water tank through an air supply assembly.

[0009] Preferably, the float assembly further includes a shape control component, which includes a lower limit plate and a support net; the lower limit plate is parallel to the upper limit plate, and a plurality of second guide rods are provided around the lower limit plate, the second guide rods being slidably connected to the upper limit plate; the two ends of the support net are respectively connected to the upper limit plate and the lower limit plate.

[0010] Preferably, the pontoon assembly also includes multiple support components, which are equally spaced between the upper limit plate and the lower limit plate. The support components are used to provide support force to the support net toward the center of the support net.

[0011] Preferably, the shape control component further includes a plurality of second springs, which are respectively sleeved on a plurality of second guide rods, and the two ends of the second springs abut against the ends of the second guide rods and the upper limit plate, respectively.

[0012] Preferably, the elastic reset assembly includes a first pull rod and a guide reset assembly; the two ends of the first pull rod are respectively hinged to the first support arm and the guide reset assembly; the guide reset assembly is disposed at the upper end of the ballast water tank, and the guide reset assembly is used to limit the movement path of one end of the first pull rod and push one end of the first pull rod to reset.

[0015] Preferably, the airway control assembly further includes two unblocking components, which are respectively connected to two extrusion plates and are used to drive the two extrusion plates away from each other.

[0016] The advantages of this invention compared to the prior art are:

[0017] 1. This invention features an anti-tipping structure. The ballast water tank utilizes the natural inflow of seawater to compress air and generate high pressure. This, combined with an air duct valve that automatically detects and controls the pressure difference, allows the air supply assembly to supply air to the float assembly without external power. This causes the float assembly to automatically expand and generate buoyancy, achieving initial stability and subsequent tilt adjustment of the buoy. The tilted ballast water tank, due to its increased volume, rapidly draws in more seawater, increasing the internal air pressure. The air duct valve opens immediately, allowing high-pressure air to flow rapidly to the float assembly, further expanding it and increasing buoyancy. Simultaneously, the support arm assembly maintains the float assembly's stable position, and the elastic reset assembly converts buoyancy into a reset force, quickly resetting the ballast water tank. The coordinated action of these components rapidly generates a reverse adjustment force, effectively suppressing the tilting and swaying of the buoy and ensuring its normal operation under complex sea conditions.

[0018] 2. This invention features a first arm and a second arm. During transportation, the second arm is housed within the first arm, resulting in a compact support arm assembly. The distance between the buoy assembly and the center of the buoy body is small, reducing the overall volume of the buoy. After the buoy is deployed to the sea surface, the ballast tank generates high pressure by compressing air through the inflow of seawater. The pressure difference is detected and automatically opened by the air duct valve, allowing high-pressure air to enter the air supply assembly. The air supply assembly uses the high-pressure air to push the second arm out from within the first arm, causing the buoy assembly to move and increase the distance between it and the center of the buoy body. The first and second arms form a longer lever arm, thereby enhancing the adjustment torque for tilting the buoy body.

[0019] 3. This invention features an upper limit plate and a buoy airbag. The upper limit plate restricts the expansion direction of the buoy airbag, guiding it to expand primarily downwards. This ensures the buoy airbag can fully contact the seawater, efficiently generating upward buoyancy and providing a basis for buoy stability and adjustment. When the buoy tilts, the air pressure in the ballast tank on the tilted side increases, and more air enters the buoy airbag through the air supply assembly, causing it to expand further and increasing buoyancy. This, combined with the support arm assembly, pushes the buoy back to its original position. When the buoy returns to its original position, the air pressure in the ballast tank decreases, the air inside the buoy airbag flows back, and the buoy airbag contracts. The buoy airbag is connected to the ballast tank through the air supply assembly, thus enabling flexible changes in the air pressure inside the ballast tank. Attached Figure Description

Detailed Implementation

[0032] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0033] Reference Figures 1 to 11As shown: A seawater self-ballasting split-type buoy includes a buoy body 1 and an anti-tipping structure; the buoy body 1 includes multiple ballast water tanks 11 arranged around its central axis, with water inlets at the lower end of each ballast water tank 11 and air valves 12 for detecting air pressure at both ends installed at the upper end of each ballast water tank 11; the anti-tipping structure includes a mounting base 2 and multiple buoyancy self-adjusting structures 3, the mounting base 2 being located in the middle of the multiple ballast water tanks 11, and the multiple buoyancy self-adjusting structures 3 corresponding to the multiple ballast water tanks 11 respectively, the buoyancy self-adjusting structures... The structure 3 includes a support arm assembly 31, an elastic reset assembly 32, a float assembly 33, and an air supply assembly 35. One end of the support arm assembly 31 is hinged to the mounting base 2. The two ends of the elastic reset assembly 32 are respectively hinged to the upper end of the ballast water tank 11 and the middle part of the support arm assembly 31. The elastic reset assembly 32 is used to provide a pulling force to the support arm assembly 31 toward the ballast water tank 11. The float assembly 33 is connected to the other end of the support arm assembly 31. The two ends of the air supply assembly 35 are respectively connected to the airway valve 12 and the float assembly 33.

[0034] When seawater is placed on the sea surface from the ballast split buoy body 1, the seawater will naturally flow into the ballast water tank 11 through the water inlet at the lower end of the ballast water tank 11 on the buoy body 1. As seawater continues to enter, the air inside the ballast water tank 11 is gradually compressed, causing the air pressure inside the ballast water tank 11 to continuously increase. At this time, the air duct valve 12 installed at the upper end of the ballast water tank 11 can detect the air pressure difference between its two ends. When the pressure difference reaches a set threshold, the air duct valve 12 automatically opens, and the high-pressure air inside the ballast water tank 11 flows to the corresponding float assembly 33 through the air supply component 35. This causes the float assembly 33 to expand and come into contact with seawater, thus generating upward buoyancy. When the air pressure inside and outside the ballast tank 11 gradually equalizes, and there is no pressure difference on both sides of the air duct valve 12 or the pressure difference is within the allowable error range, the air duct valve 12 closes. When the buoy body 1 tilts and sways due to wind and waves, the volume of the ballast tank 11 on the tilted side of the buoy body 1 increases below the water surface, and more seawater enters the ballast tank 11 through the inlet, causing the air pressure inside the ballast tank 11 to rise again. Due to the pressure difference at both ends, the air duct valve 12 opens again, and the ballast tank... Air within ballast tank 11 flows continuously through air supply assembly 35 to the corresponding float assembly 33, causing the float assembly 33 to expand further, thus increasing its buoyancy. Simultaneously, during the tilting process of ballast tank 11, the corresponding support arm assembly 31 rotates around its hinge point with the mounting base 2, maintaining the relative position of the float assembly 33. The increased buoyancy of the float assembly 33 is transmitted through the support arm assembly 31 to the elastic reset assembly 32. The elastic reset assembly 32 exerts a pulling force on the support arm assembly 31 towards the ballast tank 11. This pulling force acts on... Ballast water tank 11 is pushed upward to reset. During the reset process, the internal space of ballast water tank 11 increases and the internal air pressure decreases. The air passage valve 12 opens again, and air flows back from float assembly 33 to ballast water tank 11 through air supply assembly 35. The buoyancy of float assembly 33 decreases, and buoy body 1 gradually returns to a stable state. Through the synergistic effect of ballast water tank 11 and float assembly 33, it can quickly respond and generate reverse adjustment force, thereby effectively suppressing the tilting and swaying of buoy body 1 and ensuring that buoy body 1 can work normally under complex sea conditions.

[0035] Reference Figure 4 and Figure 5 As shown: The support arm assembly 31 includes a first arm 311 and a second arm 312; one end of the first arm 311 is hinged to the mounting base 2; one end of the second arm 312 is slidably disposed inside the first arm 311, and the other end of the second arm 312 is connected to the float assembly 33; the air supply assembly 35 is disposed inside the first arm 311 and the second arm 312; when the air in the ballast water tank 11 flows to the air supply assembly 35, the air supply assembly 35 first pushes the second arm 312 to slide along the first arm 311.

[0036] During the transportation of the seawater self-ballast split buoy, to save space and facilitate transportation, the second arm 312 is housed within the first arm 311. At this time, the distance between the buoy box assembly 33 and the middle of the buoy body 1 is small, and the entire support arm assembly 31 is in a compact state. When the buoy body 1 is placed on the sea surface, seawater enters the ballast water tank 11 through the water inlet at the lower end of the ballast water tank 11. As seawater is continuously injected, the air inside the ballast water tank 11 is compressed, and the air pressure inside the tank gradually increases. When the air pressure increases to the point that a sufficient pressure difference is generated across the air passage valve 12, the air passage valve 12 opens, and the high-pressure air inside the ballast water tank 11 enters the air supply assembly 35. At this time, the high-pressure air in the air supply assembly 35 will... First, a thrust is generated on the second arm 312, pushing the second arm 312 to slide along the inside of the first arm 311, causing the second arm 312 to extend out from the first arm 311. As the second arm 312 extends, the position of the float assembly 33 connected to the other end of the second arm 312 moves, and the distance between the float assembly 33 and the middle of the buoy body 1 increases accordingly. After the second arm 312 extends to the appropriate position, the air supply assembly 35 continues to supply high-pressure air to the float assembly 33, causing the float assembly 33 to expand and enter the subsequent buoyancy adjustment stage. The first arm 311 and the second arm 312 form a longer lever arm, thereby enhancing the adjustment torque on the tilt of the buoy body 1.

[0037] Reference Figure 4 , Figure 5 and Figure 6 As shown: The float assembly 33 includes an upper limit plate 331 and a float airbag 332; the upper limit plate 331 is connected to the end of the second support arm 312; the float airbag 332 is located at the lower end of the upper limit plate 331, and the float airbag 332 is connected to the ballast water tank through the air supply assembly 35.

[0038] During the transportation of the seawater self-ballast split buoy, the second arm 312 retracts into the first arm 311, and the float assembly 33 is in a compact state along with the second arm 312. At this time, the float airbag 332 is not inflated and maintains a small volume. The upper limit plate 331 plays a certain role in storing and protecting the float airbag 332, preventing it from being subjected to unnecessary compression or damage during transportation. When the buoy body 1 is placed on the sea surface, high-pressure air is first pushed by the air supply assembly 35 to extend the second arm 312 out of the first arm 311. Then, the air supply assembly 35 continues to deliver high-pressure air to the float airbag 332, and the float airbag 332 begins to inflate. Since the float airbag 332 is located at the lower end of the upper limit plate 331, the upper limit plate... Plate 331 can limit the expansion direction of buoy airbag 332, guiding buoy airbag 332 to expand mainly downwards so that it can contact seawater. When the buoy body 1 tilts, the air pressure in the ballast water tank 11 on the tilted side increases, and more air enters the buoy airbag 332 of the corresponding buoy assembly 33 through the air supply component 35. The buoy airbag 332 expands further, increasing buoyancy. Together with the support arm assembly 31 and other structures, it pushes the buoy body 1 back to its original position. When the buoy body 1 returns to its original position, the air pressure in the ballast water tank 11 decreases, and the air in the buoy airbag 332 flows back to the ballast water tank 11. The buoy airbag 332 contracts and is connected to the ballast water tank 11 through the air supply component 35, thereby realizing flexible changes in the air pressure in the ballast water tank 11.

[0039] Reference Figure 6 and Figure 7 As shown: the float assembly 33 also includes a shape control assembly 333, which includes a lower limit plate 3331 and a support net 3333; the lower limit plate 3331 is parallel to the upper limit plate 331, and a plurality of second guide rods 3332 are provided around the lower limit plate 3331, which are slidably connected to the upper limit plate 331; the two ends of the support net 3333 are respectively connected to the upper limit plate 331 and the lower limit plate 3331.

[0040] During the transportation phase, the float airbag 332 is not inflated and is small in size. The support net 3333 is in a loose state. The upper limit plate 331 and the lower limit plate 3331 together provide containment and protection for the float airbag 332. When the buoy body 1 is deployed to the sea surface, the air pressure in the ballast water tank 11 increases, causing the airway valve 12 to open. High-pressure air enters the float airbag 332, and the float airbag 332 begins to inflate. Because the float airbag 332 is attached to the inside of the support net 3333, it is constrained by the support net 3333 during the expansion process. At the same time, it exerts a force on the lower limit plate 3331 away from the upper limit plate 331. Under this force, the lower limit plate 3331 drives the second guide rod 3332 away from the central axis of the upper limit plate 331. The upper limit plate 331 and the support net 3333 gradually unfold as the lower limit plate 3331 moves. The unfolded support net 3333 cooperates with the upper limit plate 331 and the lower limit plate 3331 to guide its uniform and regular expansion, avoiding excessive local bulging or irregular shape. When the buoy body 1 tilts, the air pressure in the tilted side ballast tank 11 further increases, and more air enters the float airbag 332 to make it continue to expand. The thrust of the float airbag 332 on the lower limit plate 3331 increases, and the lower limit plate 3331 drives the second guide rod 3332 to slide further. The support net 3333 continues to unfold. The regular expansion shape ensures that the contact area between the float airbag 332 and the seawater is maximized, thereby improving the efficiency and stability of buoyancy generation.

[0041] Reference Figure 6 and Figure 7 As shown: The floating box assembly 33 also includes a plurality of support assemblies 334, which are equally spaced between the upper limit plate 331 and the lower limit plate 3331. The support assemblies 334 are used to provide support force to the support net 3333 towards the center of the support net 3333.

[0042] Specifically, the support component 334 includes a support ring 3341, the inner side of which is connected to the support net 3333, and the outer side of the support net 3333 is provided with a plurality of sliders 3342, which are slidably connected to a plurality of second guide rods 3332 respectively. A third spring 3343 is provided between two adjacent sliders 3342 on the same second guide rod 3332.

[0043] High-pressure air enters the float airbag 332, causing it to expand. However, due to the radial support force of the support component 334, the float airbag 332 cannot expand excessively radially. Instead, it expands axially (up and down) along the second guide rod 3332. The thrust generated by the axial expansion of the float airbag 332 acts on the lower limit plate 3331, pushing the lower limit plate 3331 and causing the second guide rod 3332 to move outward from the upper limit plate 331. During this process, the second guide rod 3332 and the slider 3342 slide relative to each other. The slider 3342 always maintains a stable sliding state along the second guide rod 3332, without affecting the deployment of the support net 3333. As the float airbag 332 enters the seawater, it expands axially in a directional manner, generating a more concentrated and stable buoyancy. Combined with the uniform radial support force of the support component 334, this makes the buoyancy point more stable and allows for a faster and more precise response to the tilt adjustment needs of the buoy body 1.

[0044] Reference Figure 6 and Figure 7 As shown: The shape control component 333 also includes a plurality of second springs 3334, which are respectively sleeved on a plurality of second guide rods 3332. The two ends of the second springs 3334 abut against the ends of the second guide rods 3332 and the upper limit plate 331, respectively.

[0045] The second spring 3334 is used to apply a force toward the upper limit plate 331 to the lower limit plate 3331 via the second guide rod 3332. During the expansion of the float airbag 332, the float airbag 332 will apply a force to the lower limit plate 3331. When this force exceeds the force applied toward the upper limit plate 331 by the second spring 3334 via the second guide rod 3332, the lower limit plate 3331 overcomes the resistance of the second spring 3334 and moves away from the upper limit plate 331 along the second guide rod 3332. During this process, the second spring 3334 sleeved on the second guide rod 3332 is compressed, and the elastic force generated by its deformation gradually increases with the increase of the compression, forming a reverse force opposite to the thrust of the airbag. When the buoy body 1 gradually... During the gradual reset, the float airbag 332 contracts, and the force exerted by the float airbag 332 on the lower limit plate 3331 gradually decreases. When the force is less than the force of the second spring 3334, the second spring 3334 pushes the second guide rod 3332 towards the upper limit plate 331 under its own rebound force. The lower limit plate 3331 resets synchronously with the second guide rod 3332, the support net 3333 gradually relaxes, and the second spring 3334 gradually returns to its initial state, waiting for the next adjustment. The second spring 3334 applies a spring force towards the upper limit plate 331 to the lower limit plate 3331 through the second guide rod 3332, causing the upper and lower limit plates 3331 to move closer to each other, forming a tight wrapping protection for the float airbag 332, thereby reducing the risk of collision damage to the airbag during transportation.

[0046] Reference Figure 4 , Figure 8 and Figure 9 As shown: The elastic reset assembly 32 includes a first pull rod 321 and a guide reset assembly 322; the two ends of the first pull rod 321 are respectively hinged to the first support arm 311 and the guide reset assembly 322; the guide reset assembly 322 is disposed at the upper end of the ballast water tank 11, and the guide reset assembly 322 is used to limit the movement path of one end of the first pull rod 321 and push one end of the first pull rod 321 to reset.

[0047] Specifically, the guide reset assembly 322 includes a first guide rod 3221 and a moving block 3223. There are multiple first guide rods 3221, which are parallel to each other, and each of the multiple first guide rods 3221 is fitted with a first spring 3222. The moving block 3223 is slidably connected to the multiple first guide rods 3221, and the moving block 3223 abuts against the first spring 3222.

[0048] One end of the first support arm 311 is hinged to the mounting base 2, and the other end is stabilized due to the position of the float assembly 33. As a result, the angle between the first support arm 311 and the upper surface of the ballast tank 11 during the tilting process gradually increases. The angle of the first tie rod 321 changes synchronously with the first support arm 311. The other end of the first tie rod 321 is hinged to the moving block 3223. Following the downward tilting trend of the ballast tank 11, the moving block 3223 slides along the first guide rod 3221 away from the tilting direction of the ballast tank 11. During the sliding process of the moving block 3223, it is compressed against the first spring 3222 on the first guide rod 3221. The first spring 3222 is compressed due to deformation and gradually stores elastic potential energy. At the same time, the first spring 3222 generates a reverse elastic force on the moving block 3223. This elastic force is transmitted to the first support arm 311 through the first tie rod 321, initially forming... To counteract the resistance to tilting of the buoy body 1 and slow down the tilting speed, preparing for subsequent repositioning, when the buoy body 1 repositions, the first spring 3222 releases its stored elastic potential energy, generating a thrust on the moving block 3223 along the first guide rod 3221 pointing to the initial position. This pushes the moving block 3223 to slide in the opposite direction along the first guide rod 3221, thereby pulling the ballast tank 11 upwards to reposition. The greater the tilt angle of the buoy body 1, the farther the moving block 3223 slides, the greater the compression of the first spring 3222, and the more stored elastic potential energy, resulting in stronger resistance to tilting and stronger power for subsequent repositioning. Conversely, when the tilt angle is small, the spring compression is small and the elastic force is moderate, avoiding over-adjustment. This ensures that the buoy body 1 can quickly reposition under strong winds and waves, while avoiding over-adjustment under light winds and waves, significantly improving the accuracy of the anti-tipping response of the buoy body 1 under different sea conditions.

[0049] Reference Figure 4 and Figure 10As shown: the gas supply assembly 35 includes a primary gas supply pipe 351 and a secondary gas supply pipe 352; the primary gas supply pipe 351 is located inside the first support arm 311 and outside the second support arm 312, and the primary gas supply pipe 351 can extend and retract along the length direction of the first support arm 311; the two ends of the secondary gas supply pipe 352 are respectively connected to the primary gas supply pipe 351 and the float assembly 33.

[0050] In the initial state before the buoy body 1 is transported and deployed to the sea surface, the primary air supply pipe 351 is in a contracted state, with the entire structure folded or compressed. At this time, the secondary air supply pipe 352 is located inside the second support arm 312, ensuring the structural compactness of the buoy body 1 during transportation and avoiding damage caused by excessive extension of the air supply pipe. After the buoy body 1 is placed in the seawater, the air in the ballast tank 11 is continuously compressed, the air passage valve 12 opens, and the high-pressure air in the ballast tank 11 first enters the primary air supply pipe 351. The air pressure rises rapidly, causing the primary gas delivery pipe 351 to expand. Because the primary gas delivery pipe 351 is confined between the inner wall of the first support arm 311 and the outer wall of the second support arm 312, its radial expansion space is restricted. Therefore, it can only expand directionally along the length of the first support arm 311 (i.e., the extension / retraction direction of the second support arm 312). As the primary gas delivery pipe 351 expands along its length, the side near the end of the second support arm 312 will generate a continuous thrust on the end of the second support arm 312. When this thrust overcomes the pressure of the second support arm 311… When the sliding friction and initial constraint resistance between the second arm 312 and the first arm 311 are equal, the second arm 312 begins to slide along its length within the first arm 311 and gradually extends outward. During the extension of the second arm 312, the primary air supply pipe 351 remains in an expanded state to ensure stable thrust on the second arm 312 until the second arm 312 extends to a preset length (or the primary air supply pipe 351 expands to its maximum extension limit). Then, high-pressure air enters the secondary air supply pipe 352, which delivers high-pressure air. Air is delivered to the buoy airbag 332, causing it to inflate and expand, thus generating buoyancy by contacting seawater. This initiates the overall stabilization and adjustment phase of the buoy body 1. The air delivery component 35 utilizes the high-pressure air generated by the compression of seawater in the ballast tank 11 as a power source to drive the expansion of the first-stage air delivery pipe 351 and push the second support arm 312 to extend. This eliminates the need for external power devices such as motors and hydraulic systems, thereby reducing the energy consumption and manufacturing cost of the buoy body 1, minimizing mechanical failure points, and improving the operational reliability of the buoy body 1 under complex sea conditions.

[0051] Reference Figure 4 and Figure 10As shown: the buoyancy self-adjusting structure 3 also includes an air passage control component 36, which includes a squeezing plate 361 and a squeezing guide component 362; there are two squeezing plates 361 arranged parallel to each other on both sides of the air delivery component 35; the squeezing guide component 362 is used to apply opposing thrusts to the two squeezing plates 361.

[0052] Specifically, the extrusion guide assembly 362 includes two brackets 3621 and multiple third guide rods 3622. The two brackets 3621 are respectively disposed on the outer side of the two extrusion plates 361, and both brackets 3621 are fixedly connected to the end of the second support arm 312 that extends into the first support arm 311. The multiple third guide rods 3622 are arranged parallel to each other, and the two ends of the third guide rods 3622 are respectively connected to the two brackets 3621. The two extrusion plates 361 are slidably connected to the two ends of the third guide rods 3622. A fourth spring 3623 is sleeved on both ends of the third guide rods 3622. The two ends of the fourth spring 3623 abut against the end of the third guide rod 3622 and the extrusion plate 361, respectively. The fourth spring 3623 is used to apply a thrust to the extrusion plate 361 toward the middle of the third guide rod 3622.

[0053] The fourth springs 3623 at both ends of the third guide rod 3622 apply opposing thrusts toward the middle of the two extrusion plates 361. Under the action of this thrust, the two parallel extrusion plates 361 approach each other, squeezing the secondary air supply pipe 352 located between them, causing the lumen of the secondary air supply pipe 352 to be cut off, forming a sealed blocking state. When the buoy body 1 is placed in seawater, the seawater filling in the ballast water tank 11 causes the air pressure to rise, and the air passage valve 12 opens. The high-pressure air can only be confined within the primary air supply pipe 351. As the high-pressure air in the primary air supply pipe 351 continues to accumulate, its internal air pressure continues to rise, pushing the primary air supply pipe 351 to expand directionally along the length of the first support arm 311, thereby generating a stable thrust on the end of the second support arm 312, causing the second support arm 312 to begin to expand in the first support arm 311. When the second arm 312 extends to the preset length, the high-pressure air in the primary air supply pipe 351 acts on the two extrusion plates 361. When the two extrusion plates 361 overcome the elastic force of the fourth spring 3623, the two extrusion plates 361 slide along the third guide rod 3622 away from the middle of the third guide rod 3622, and the distance between them gradually increases. The cavity of the secondary air supply pipe 352 begins to recover its deformation. The air passage control component 36 controls the opening and closing of the secondary air supply pipe 352 through the extrusion plates 361 to ensure that the high-pressure air is all concentrated in the primary air supply pipe 351 before the second arm 312 extends to the preset length, providing sufficient power for the primary air supply pipe 351 to push the second arm 312 to extend, thereby avoiding the problem of insufficient power and slow speed of the second arm 312 extension due to air diversion.

[0054] Reference Figure 10 and Figure 11 As shown: the airway control assembly 36 also includes two unblocking assemblies 363, which are respectively connected to two extrusion plates 361. The two unblocking assemblies 363 are used to drive the two extrusion plates 361 away from each other.

[0055] Specifically, the unblocking component 363 includes a second pull rod 3631, a locking block 3632, and a locking seat 3633. One end of the second pull rod 3631 is connected to the extrusion plate 361, and the other end of the second pull rod 3631 extends out of the first support arm 311 and is connected to the locking block 3632. The locking seat 3633 is fixed on the side wall of the first support arm 311. One side of the locking seat 3633 is provided with an inclined surface. When the locking block 3632 contacts the inclined surface of the locking seat 3633, the locking seat 3633 drives the two extrusion plates 361 to move away from each other through the locking block 3632 and the second pull rod 3631.

[0056] When the second arm 312 extends to near the preset length, the second pull rod 3631, which moves with the second arm 312, drives the locking block 3632 to the inclined surface of the locking seat 3633. The locking block 3632 contacts the inclined surface of the locking seat 3633. The inclined structure of the inclined surface converts the linear extension force of the second arm 312 into a lateral force that pulls the second pull rod 3631 away from the center of the third guide rod 3622. This lateral force is transmitted to the extrusion plate 361 through the second pull rod 3631. It is superimposed with the lateral thrust of the first-stage air pipe 351 on the extrusion plate 361, and together they overcome the opposing thrust of the fourth spring 3623 on the extrusion plate 361, pushing the extrusion plate 361 to slide away from the center along the third guide rod 3622. The distance between the two extrusion plates 361 gradually increases, and the extrusion pressure on the second-stage air pipe 352 increases. As the pressure decreases, the cavity begins to recover its deformation. At this time, the locking block 3632 passes the apex of the inclined plane and locks into the locking seat 3633, achieving a stable locking connection between the locking block 3632 and the locking seat 3633. After the locking block 3632 is locked, the second pull rod 3631 generates a continuous pulling force on the compression plate 361, keeping the compression plate 361 in the maximum sliding position along the end direction of the third guide rod 3622. The distance between the two compression plates 361 reaches its maximum. The locking connection between the locking block 3632 and the locking seat 3633 can stably fix the compression plate 361 in the separation position after the second support arm 312 reaches the preset length, thereby ensuring that the secondary air supply pipe 352 remains continuous during the adjustment of the buoy body 1, providing continuous buoyancy support for the float airbag 332 and avoiding a decrease in the stability of the buoy body 1 due to interruption of air supply.
