Description

TECHNICAL FIELD

[0001] The present application relates to the field of ocean buoys, in particular to a seawater self-ballast split type buoy. BACKGROUND

[0002] In the field of ocean monitoring, channel marking, environmental detection and other ocean-related fields, buoys are widely used as key equipment, which need to work stably for a long time in complex sea conditions to ensure the normal realization of data acquisition, signal transmission and other functions. However, the current buoy products on the market still have many problems to be solved in structure design and working performance, which are difficult to meet the efficient and stable demand in actual application. In order to make the buoy stability meet the design requirements, it is necessary to reduce the buoy gravity center and make the buoy reach the designed draft, which requires additional ballast for the buoy. In the prior art, high-density substances such as cement or ballast iron are generally used as ballast, and the weight of these additional ballast is an important factor for the increase of construction, transportation and maintenance costs of the buoy.

[0003] The patent with publication number CN214356541U discloses a buoy using seawater self-ballast, which sets a ballast water tank in the buoy body to provide ballast effect by using seawater naturally entering the tank, without the need for additional ballast such as cement and ballast iron, effectively reducing the overall weight during the hoisting and recovery process of the buoy, reducing the construction, operation and maintenance costs of the buoy, and reducing the equipment requirements for offshore operation vessels, to a certain extent, improving the safety of offshore operations and providing a new idea for lightweight design of the buoy.

[0004] Although the above-mentioned scheme provides ballast effect by seawater entering the ballast water tank without additional ballast, the stability of the scheme in complex marine environment still has obvious defects. In the marine environment, ocean current impact and wave disturbance are normal, and such external forces can easily cause the buoy to tilt and swing. When the buoy tilts, the ballast water tank on the downward tilting side will surge more seawater due to the increase of water depth, and the ballast water tank on the upward tilting side will flow out part of the seawater due to the drop of water level. This phenomenon will cause the gravity center of the buoy to shift sharply, further aggravating the tilting degree of the buoy. If the tilting angle exceeds the safety threshold, it will not only affect the normal working accuracy of the monitoring equipment on the buoy, but also may cause the buoy to overturn due to gravity imbalance, seriously threatening the structural safety and operation stability of the buoy, and cannot meet the demand of long-term reliable work in complex sea conditions.

DETAILED DESCRIPTION

[0031] In order to further understand the features, technical means and specific purposes and functions achieved by the present application, the present application will be described in further detail below in conjunction with the drawings and specific embodiments.

[0032] REFERENCE Figures 1 to 11The application discloses a seawater self-ballast split type buoy, which comprises a buoy main body 1 and an anti-toppling structure; the buoy main body 1 comprises a plurality of ballast water tanks 11 arranged around a middle axis of the buoy main body 1, the lower end of each ballast water tank 11 is provided with a water inlet, and the upper end of each ballast water tank 11 is provided with an air passage valve 12 capable of detecting air pressure at two ends; the anti-toppling structure comprises a mounting seat 2 and a plurality of buoyancy self-adjusting structures 3, the mounting seat 2 is arranged at the middle part of the plurality of ballast water tanks 11, the plurality of buoyancy self-adjusting structures 3 are correspondingly arranged with the plurality of ballast water tanks 11, the buoyancy self-adjusting structure 3 comprises a support arm assembly 31, an elastic reset assembly 32, a float box assembly 33 and a gas conveying assembly 35, one end of the support arm assembly 31 is hinged to the mounting seat 2, the two ends of the elastic reset assembly 32 are hinged to the upper end of the ballast water tank 11 and the middle part of the support arm assembly 31 respectively, the elastic reset assembly 32 is used for providing a pulling force to the support arm assembly 31 towards the ballast water tank 11, the float box assembly 33 is connected to the other end of the support arm assembly 31, and the two ends of the gas conveying assembly 35 are connected to the air passage valve 12 and the float box assembly 33 respectively.

[0033] When the seawater self-ballast split buoy main body 1 is placed on the sea surface, the seawater will flow into the ballast tank 11 through the water inlet hole at the lower end of the buoy main body 1. As the seawater continues to enter, the air in the ballast tank 11 is gradually squeezed, causing the air pressure in the ballast tank 11 to continue to rise. At this time, the air valve 12 installed at the upper end of the ballast tank 11 can detect the air pressure difference between the two ends. When the pressure difference reaches the set threshold, the air valve 12 automatically opens, and the high-pressure air in the ballast tank 11 flows to the corresponding float assembly 33 through the air supply assembly 35, prompting the float assembly 33 to expand and contact with the seawater. The float assembly 33 thus generates upward buoyancy. When the air pressure inside and outside the ballast tank 11 gradually balances, and there is no pressure difference or the pressure difference is within the allowable error range, the air valve 12 closes. When the buoy main body 1 is tilted and shaken by wind and waves, the volume of the ballast tank 11 on the tilted side of the buoy main body 1 increases below the water surface, and more seawater enters the ballast tank 11 through the water inlet hole, causing the air pressure in the ballast tank 11 to rise again. The air valve 12 opens again due to the pressure difference between the two ends, and the air in the ballast tank 11 continues to flow to the corresponding float assembly 33 through the air supply assembly 35, causing the float assembly 33 to further expand and increase the buoyancy it provides. At the same time, during the tilting of the ballast tank 11, the corresponding support arm assembly 31 will rotate around its hinge with the mounting seat 2, keeping the relative position of the float assembly 33 unchanged. The increased buoyancy of the float assembly 33 is transmitted to the elastic reset assembly 32 through the support arm assembly 31, which generates a pulling force towards the ballast tank 11 on the support arm assembly 31. This pulling force acts on the ballast tank 11, pushing the ballast tank 11 upwards to reset. During the resetting of the ballast tank 11, the space inside the ballast tank 11 increases, and the internal air pressure decreases. The air valve 12 opens again, and the air flows back to the ballast tank 11 from the float assembly 33 through the air supply assembly 35. The buoyancy of the float assembly 33 decreases, and the buoy main body 1 gradually returns to a stable state. Through the cooperation of the ballast tank 11 and the float assembly 33, the buoy main body 1 can quickly respond and generate a reverse adjusting force, effectively suppressing the tilting and shaking of the buoy main body 1, and ensuring that the buoy main body 1 can work normally in complex sea conditions.

[0034] Referring to Figure 4 and Figure 5 , the support arm assembly 31 includes a first support arm 311 and a second support arm 312. One end of the first support arm 311 is hinged to the mounting seat 2. One end of the second support arm 312 is slidingly arranged in the first support arm 311, and the other end of the second support arm 312 is connected to the float assembly 33. The air supply assembly 35 is arranged in the first support arm 311 and the second support arm 312. When the air in the ballast tank 11 flows to the air supply assembly 35, the air supply assembly 35 first pushes the second support arm 312 to slide along the first support arm 311.

[0035] In the process of transporting seawater from the ballast split type buoy, in order to save space and facilitate transportation, the second branch arm 312 is stored in the first branch arm 311, at this time the distance between the float tank assembly 33 and the middle part of the buoy body 1 is small, the whole support arm assembly 31 is in a compact state, when the buoy body 1 is placed on the sea surface, seawater enters the ballast tank 11 through the water inlet hole at the lower end of the ballast tank 11, as the seawater continues to be injected, the air in the ballast tank 11 is squeezed, the air pressure in the tank gradually rises, when the air pressure rises to make the air passage valve 12 both ends produce enough pressure difference, the air passage valve 12 opens, the high pressure air in the ballast tank 11 enters the gas conveying assembly 35, at this time, the high pressure air in the gas conveying assembly 35 will first generate a thrust on the second branch arm 312, push the second branch arm 312 to slide along the inside of the first branch arm 311, make the second branch arm 312 stretch out from the first branch arm 311, as the second branch arm 312 stretches out, the position of the float tank assembly 33 connected with the other end of the second branch arm 312 moves, the distance between the float tank assembly 33 and the middle part of the buoy body 1 increases, after the second branch arm 312 stretches out to the appropriate position, the gas conveying assembly 35 continues to convey high pressure air to the float tank assembly 33, make the float tank assembly 33 swell, enter the subsequent buoyancy adjustment stage, through the first branch arm 311 and the second branch arm 312 to form a longer force arm, so as to enhance the adjustment torque of the buoy body 1 inclination.

[0036] Referring to Figure 4 , Figure 5 and Figure 6 : the float tank assembly 33 includes an upper limiting plate 331 and a float tank air bag 332; the upper limiting plate 331 is connected with the end of the second branch arm 312; the float tank air bag 332 is arranged at the lower end of the upper limiting plate 331, and the float tank air bag 332 is connected with the ballast tank through the gas conveying assembly 35.

[0037] In the process of transporting seawater from the self-ballast split buoy, the second branch arm 312 is retracted in the first branch arm 311, the float tank assembly 33 is with the second branch arm 312 in a compact state, at this time, the float tank air bag 332 is not inflated, maintains a small volume, and the upper limiting plate 331 plays a certain storage and protection role on the float tank air bag 332, avoiding unnecessary extrusion or damage to the float tank air bag 332 in the transportation process, when the buoy main body 1 is placed on the sea surface, high-pressure air pushes the second branch arm 312 out of the first branch arm 311 through the air conveying assembly 35, then the air conveying assembly 35 continues to convey high-pressure air to the float tank air bag 332, and the float tank air bag 332 starts to inflate and expand, because the float tank air bag 332 is arranged at the lower end of the upper limiting plate 331, the upper limiting plate 331 can limit the expansion direction of the float tank air bag 332, guide the float tank air bag 332 to mainly expand downward, so that it can contact with seawater, when the buoy main body 1 is inclined, the air pressure in the ballast tank 11 on the inclined side rises, more air enters the float tank air bag 332 of the corresponding float tank assembly 33 through the air conveying assembly 35, the float tank air bag 332 further expands, the buoy main body 1 is reset by the buoy main body 1, and the buoy main body 1 is reset, the air pressure in the ballast tank 11 decreases, the air in the float tank air bag 332 flows back to the ballast tank 11, and the float tank air bag 332 is contracted, so that the air pressure in the ballast tank 11 changes flexibly.

[0038] Referring to Figure 6 and Figure 7 As shown: the float tank assembly 33 further includes a shape control assembly 333, the shape control assembly 333 includes a lower limiting plate 3331 and a support net 3333; the lower limiting plate 3331 is parallel to the upper limiting plate 331, a plurality of second guide rods 3332 are arranged around the lower limiting plate 3331, and the second guide rods 3332 are slidably connected with the upper limiting plate 331; the two ends of the support net 3333 are connected with the upper limiting plate 331 and the lower limiting plate 3331 respectively.

[0039] In the transportation stage, the buoyancy chamber 332 is not inflated, small in size, the support net 3333 is in a relaxed state, and the upper limiting plate 331 and the lower limiting plate 3331 jointly form a storage protection for the buoyancy chamber 332. After the buoyant body 1 is thrown into the sea, the air pressure in the ballast water tank 11 rises to open the air valve 12, high-pressure air enters the buoyancy chamber 332, and the buoyancy chamber 332 starts to inflate and expand. Since the buoyancy chamber 332 is attached to the inside of the support net 3333, it will be constrained by the support net 3333 during the expansion process, and at the same time, it will exert a force on the lower limiting plate 3331 away from the upper limiting plate 331. Under the action of the force, the lower limiting plate 3331 drives the second guide rod 3332 to move away from the upper limiting plate 331 along the central axis of the upper limiting plate 331. The support net 3333 expands gradually with the movement of the lower limiting plate 3331, and the expanded support net 3333 cooperates with the upper limiting plate 331 and the lower limiting plate 3331 to guide the uniform and regular expansion, avoiding local over-inflation or irregular shape. When the buoyant body 1 is tilted, the air pressure in the ballast water tank 11 on the tilted side further rises, more air enters the buoyancy chamber 332 to make it continue to expand, and the buoyancy chamber 332 exerts a greater force on the lower limiting plate 3331. The lower limiting plate 3331 drives the second guide rod 3332 to further slide, and the support net 3333 continues to expand. Through the regular expansion shape, the buoyancy chamber 332 maximizes the contact area with seawater, thereby improving the efficiency and stability of the generated buoyancy.

[0040] Referring to Figure 6 and Figure 7 The buoyancy assembly 33 further includes a plurality of support assemblies 334, which are arranged at equal intervals between the upper limiting plate 331 and the lower limiting plate 3331. The support assemblies 334 are used to provide a support force to the support net 3333 towards the center of the support net 3333.

[0041] Specifically, the support assembly 334 includes a support ring 3341, the inner side of the support ring 3341 being connected with the support net 3333, and the outer side of the support net 3333 being provided with a plurality of sliding blocks 3342. The plurality of sliding blocks 3342 are respectively connected with the plurality of second guide rods 3332 in sliding mode, and a third spring 3343 is arranged between two adjacent sliding blocks 3342 on the same second guide rod 3332.

[0042] High-pressure air enters the buoyancy air bag 332, the buoyancy air bag 332 starts to expand, and the buoyancy air bag 332 cannot over-expand in the radial direction due to the radial support force of the support assembly 334, but expands in the axial direction (up and down direction) along the second guide rod 3332. The axial expansion of the buoyancy air bag 332 generates a pushing force acting on the lower limit plate 3331, which pushes the lower limit plate 3331 to move the second guide rod 3332 outward of the upper limit plate 331. In this process, the second guide rod 3332 slides relative to the sliding block 3342, and the sliding block 3342 always keeps a stable sliding state along the second guide rod 3332, without affecting the expansion of the support net 3333. In the process of the buoyancy air bag 332 entering the sea water, the buoyancy air bag 332 expands in the axial direction, which can generate more concentrated and stable buoyancy, and the uniform radial support force of the support assembly 334 can make the buoyancy action point more stable, so that the buoyancy can respond more quickly and accurately to the inclination adjustment demand of the buoyancy body 1.

[0043] Referring to Figure 6 and Figure 7 As shown in the drawings: The shape control assembly 333 further includes a plurality of second springs 3334, and the plurality of second springs 3334 are respectively sleeved on the plurality of second guide rods 3332. The two ends of the second spring 3334 respectively abut against the end of the second guide rod 3332 and the upper limit plate 331.

[0044] The second spring 3334 is used to apply a force to the lower limit plate 3331 through the second guide rod 3332, and the force is directed towards the upper limit plate 331. In the process of the expansion of the buoyancy air bag 332, the buoyancy air bag 332 will apply a force to the lower limit plate 3331. When the force exceeds the force applied by the second spring 3334 to the lower limit plate 3331 through 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. In this process, the second spring 3334 sleeved on the second guide rod 3332 is compressed, and the elastic force generated by the deformation gradually increases with the increase of the compression amount, forming a counteracting force opposite to the air bag pushing force. When the buoyancy body 1 gradually resets, the buoyancy air bag 332 contracts, the force applied by the buoyancy air bag 332 to the lower limit plate 3331 gradually decreases, and when the force is less than the force of the second spring 3334, the second spring 3334 pushes the second guide rod 3332 to move towards the upper limit plate 331 under the action of its own elastic force. The lower limit plate 3331 is reset synchronously with the second guide rod 3332, the support net 3333 gradually relaxes, and the second spring 3334 gradually returns to the initial state, waiting for the next adjustment. The second spring 3334 applies an elastic force to the lower limit plate 3331 through the second guide rod 3332, and the elastic force is directed towards the upper limit plate 331, so that the upper and lower limit plates 3331 are close to each other, and the buoyancy air bag 332 is tightly wrapped and protected, thereby reducing the risk of collision damage of the air bag during transportation.

[0045] Referring to Figure 4 , Figure 8 and Figure 9 , 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 supporting arm 311 and the guide reset assembly 322. The guide reset assembly 322 is arranged at the upper end of the ballast tank 11, and is used for limiting the movement path of one end of the first pull rod 321 and pushing the one end of the first pull rod 321 to reset.

[0046] Specifically, the guide reset assembly 322 includes a first guide rod 3221 and a moving block 3223. The first guide rod 3221 has a plurality of first guide rods 3221, which are parallel to each other. A first spring 3222 is sleeved on each of the plurality of first guide rods 3221. The moving block 3223 is slidingly connected to the plurality of first guide rods 3221, and abuts against the first spring 3222.

[0047] The first supporting arm 311 is hinged at one end to the mounting seat 2 and at the other end to the float assembly 33, which is positionally stable. Therefore, the angle between the first supporting arm 311 and the upper surface of the ballast tank 11 during tilting gradually increases. The angle of the first pull rod 321 changes synchronously with the first supporting arm 311. The other end of the first pull rod 321 is hinged to the moving block 3223 and will follow the downward tilting trend of the ballast tank 11 to drive the moving block 3223 to slide along the first guide rod 3221 to the side away from the tilting direction of the ballast tank 11. During the sliding of the moving block 3223, the moving block 3223 is extruded by 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 spring force on the moving block 3223, which is transmitted to the first supporting arm 311 through the first pull rod 321, preliminarily forming a resistance to the tilting of the buoy body 1 and delaying the tilting speed to prepare for subsequent resetting. When the buoy body 1 resets, the first spring 3222 releases the stored elastic potential energy to generate a pushing force on the moving block 3223 along the first guide rod 3221 to the initial position, pushes the moving block 3223 to slide reversely along the first guide rod 3221, and then pulls the ballast tank 11 to reset upward. The greater the tilting angle of the buoy body 1, the farther the sliding distance of the moving block 3223, and the greater the compression amount of the first spring 3222, the more the stored elastic potential energy, and the stronger the resistance to tilting and the power for subsequent resetting. Conversely, when the tilting angle is small, the spring compression amount is small, and the spring force is moderate, which avoids excessive adjustment, thereby ensuring the fast resetting of the buoy body 1 in strong wind and waves and avoiding excessive adjustment in light wind and waves, and significantly improving the response accuracy of the buoy body 1 in different sea conditions.

[0048] Referring to Figure 4 and Figure 10As shown: the gas delivery assembly 35 includes a primary gas delivery pipe 351 and a secondary gas delivery pipe 352; the primary gas delivery pipe 351 is arranged inside the first branch arm 311 and outside the second branch arm 312, and can be extended and retracted along the length direction of the first branch arm 311; the two ends of the secondary gas delivery pipe 352 are connected with the primary gas delivery pipe 351 and the buoy body 33 respectively.

[0049] In the initial state before the buoy body 1 is transported and launched into the sea, the primary gas delivery pipe 351 is in a retracted state, and the whole is in a folded or compressed state, at this time the secondary gas delivery pipe 352 is inside the second branch arm 312, which ensures the compactness of the buoy body 1 during transportation, and avoids damage caused by excessive stretching of the gas delivery pipe. When the buoy body 1 is put into the sea, the air in the ballast tank 11 is continuously squeezed, the air passage valve 12 is opened, and the high-pressure air in the ballast tank 11 first enters the primary gas delivery pipe 351, the internal pressure of which rises rapidly, pushing the primary gas delivery pipe 351 to start to expand. Since the primary gas delivery pipe 351 is limited between the inner wall of the first branch arm 311 and the outer wall of the second branch arm 312, its radial expansion space is constrained, so it can only expand in the length direction of the first branch arm 311 (i.e. the extension direction of the second branch arm 312). As the primary gas delivery pipe 351 continues to expand in the length direction, the side close to the end of the second branch arm 312 will continuously push the end of the second branch arm 312. When the pushing force overcomes the sliding friction between the second branch arm 312 and the first branch arm 311 and the initial constraint resistance, the second branch arm 312 starts to slide in the length direction inside the first branch arm 311 and gradually extends out of the first branch arm 311. During the extension of the second branch arm 312, the primary gas delivery pipe 351 continues to maintain the expansion state to ensure stable pushing force on the second branch arm 312, until the second branch arm 312 extends to the preset length (or the primary gas delivery pipe 351 expands to the maximum extension limit). Then the high-pressure air enters the secondary gas delivery pipe 352, which delivers the high-pressure air to the buoy gas bag 332, pushing the buoy gas bag 332 to inflate and expand, so that it contacts with the sea water to generate buoyancy, and enters the stable adjustment stage of the whole buoy body 1. The gas delivery assembly 35 uses the high-pressure air generated by the sea water squeezing in the ballast tank 11 as a power source to drive the primary gas delivery pipe 351 to expand and push the second branch arm 312 to extend, without relying on external power devices such as motors and hydraulic devices, thereby reducing the energy consumption and manufacturing cost of the buoy body 1, reducing the mechanical failure points, and improving the operation reliability of the buoy body 1 in complex sea conditions.

[0050] Referring to Figure 4 and Figure 10The buoy body 1 further comprises a buoy self-adjusting structure 3, the buoy self-adjusting structure 3 is arranged on the first branch arm 311, and the buoy self-adjusting structure 3 is arranged in the first branch arm 311.

[0052] The fourth springs 3623 at the two ends of the third guide rod 3622 apply a pushing force to the two extrusion plates 361 towards the middle portion of the third guide rod 3622, under the action of the pushing force, the two extrusion plates 361 arranged in parallel with each other are close to each other, and the secondary gas conveying pipe 352 located between the two extrusion plates 361 is extruded, so that the lumen of the secondary gas conveying pipe 352 is cut off to form a closed blocking state, when the buoy body 1 is placed into seawater, the seawater in the ballast tank 11 is filled to cause the air pressure to be increased, the air passage valve 12 is opened, and the high-pressure air can only be limited in the primary gas conveying pipe 351, along with the continuous accumulation of the high-pressure air in the primary gas conveying pipe 351, the internal air pressure of the primary gas conveying pipe 351 is continuously increased, the primary gas conveying pipe 351 is pushed to expand along the length direction of the first branch arm 311, and then a stable pushing force is generated on the end portion of the second branch arm 312, so that the second branch arm 312 starts to slide and extend in the first branch arm 311, when the second branch arm 312 extends to a preset length, the high-pressure air in the primary gas conveying 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 portion of the third guide rod 3622, the distance between the two extrusion plates 361 is gradually increased, and the lumen of the secondary gas conveying pipe 352 starts to recover deformation, the air passage control assembly 36 controls the on-off of the secondary gas conveying pipe 352 through the extrusion plate 361, so that the high-pressure air is entirely concentrated in the primary gas conveying pipe 351 before the second branch arm 312 extends to the preset length, sufficient power is provided for the primary gas conveying pipe 351 to push the second branch arm 312 to extend, and thus the problem that the second branch arm 312 is insufficient in power and slow in speed due to air diversion is avoided.

[0053] With reference to Figure 10 andFigure 11 As shown: airway control assembly 36 also includes two dredging assembly 363, two dredging assembly 363 is connected with two extrusion plate 361 respectively, two dredging assembly 363 is used to drive two extrusion plate 361 away from each other.

[0054] Specifically, dredging assembly 363 includes second pull rod 3631, block 3632 and card seat 3633, one end of second pull rod 3631 is connected with extrusion plate 361, the other end of second pull rod 3631 extends out of first branch 311 and is connected with block 3632, card seat 3633 is fixed on the side wall of first branch 311, one side of card seat 3633 is provided with inclined surface, when block 3632 contacts with the inclined surface of card seat 3633, card seat 3633 drives two extrusion plate 361 away from each other through block 3632 and second pull rod 3631.

[0055] When the second branch 312 extends to approach the preset length, the second pull rod 3631 moving with the second branch 312 drives the block 3632 to reach the inclined surface of the card seat 3633, the block 3632 contacts with the inclined surface of the card seat 3633, the inclined structure of the inclined surface converts the linear extension force of the second branch 312 into the transverse force of pulling the second pull rod 3631 to move away from the middle part of the third guide rod 3622, the transverse force is transmitted to the extrusion plate 361 through the second pull rod 3631, and the lateral pushing force of the first level gas conveying pipe 351 on the extrusion plate 361 is superposed, which overcomes the opposite pushing force of the fourth spring 3623 on the extrusion plate 361, and drives the extrusion plate 361 to slide along the third guide rod 3622 away from the middle part, the distance between the two extrusion plates 361 gradually increases, the extrusion force on the second level gas conveying pipe 352 decreases, and the lumen starts to recover deformation, at this time the block 3632 passes over the vertex of the inclined surface and is clamped in the card seat 3633, realizing the stable clamping of the block 3632 and the card seat 3633, after the block 3632 is locked, the second pull rod 3631 generates a continuous pulling force on the extrusion plate 361, so that the extrusion plate 361 is kept in the maximum sliding position along the end of the third guide rod 3622, the distance between the two extrusion plates 361 reaches the maximum, and the locked connection of the block 3632 and the card seat 3633 can stably fix the extrusion plate 361 in the separated position after the second branch 312 reaches the preset length, so as to ensure that the second level gas conveying pipe 352 always keeps through during the adjustment of the buoy main body 1, and provide continuous buoyancy support for the buoyancy chamber 332, avoid the decrease of stability of the buoy main body 1 caused by the interruption of gas conveying.
