[0002] Floating boxes are the main structure of floating marine components. They can provide a mobile platform for large equipment such as vehicles and engineering machinery, or be used as a wave-dissipating structure for breakwaters. Due to their modular nature, they are easy to deploy by road and rail transport.

[0003] However, the nearshore area has complex sea conditions and large waves. Affected by factors such as water depth and waves, the stability of the pontoon when moving on the water surface is poor, which affects the transfer efficiency of the pontoon and the implementation progress of the splicing operation. Utility Model Content

[0027] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0029] Floating boxes, as core components of offshore floating structures such as jetties, floating breakwaters, and floating piers, are widely used in offshore operations. They provide stable floating platforms for large equipment such as vehicles and construction machinery, and can also act as wave-damping structures in specific scenarios, reducing the impact of waves on nearshore facilities. The main advantage of floating boxes lies in their modular design, which allows them to be freely assembled into various floating platforms and jetties. This enables convenient transportation of floating boxes by road and rail, and rapid deployment, thus adapting to diverse construction needs.

[0030] Currently, the structure of floating pontoons is relatively simple, making it difficult to flexibly cope with complex marine environments. Especially in near-shore areas with large waves, the stability of the pontoons is poor when moving on the water surface due to changes in water depth and the degree of wave undulation. This is not conducive to smooth movement and precise docking on the water surface, thus affecting the transfer efficiency of the pontoons and the implementation progress of the splicing operation, which in turn affects the smooth progress of subsequent marine operations. In addition, since the pontoons lack self-propulsion capabilities, they need to be moved with the help of lifting equipment and other auxiliary tools during the splicing process. Therefore, the investment of human and material resources is large, which increases the splicing cost.

[0031] In view of this, this application provides a multifunctional floating box, combined with Figures 1-7 The multi-functional floating box provided in this application is described below.

[0032] A multifunctional floating box includes a box body 1, an external power unit 2, and at least two stabilizing components 3. The external power unit 2 is connected to the side wall of the box body 1 along its length to drive the box body 1 to move. The at least two stabilizing components 3 are respectively disposed on opposite sides of the box body 1 along its width and are symmetrically distributed relative to the box body 1 to limit the degree of sway of the box body 1. The length direction and the width direction of the box body 1 are perpendicular to each other.

[0033] For box 1, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the container 1 can provide installation positions for components such as the external power unit 2 and the stabilization component 3; and at least two adjacent pontoons can be spliced ​​together to form floating platforms or trestle structures and other floating components, providing corresponding load-bearing platforms, and can also be used as vehicles to transfer personnel, equipment and goods, improving the flexibility of pontoon applications.

[0034] For example, the buoy 1 can be made of high-strength alloy steel with strong corrosion resistance, which is beneficial to improving the overall strength and service life of the buoy.

[0035] For the external power unit 2, the external power unit 2 is connected to the side wall of the box 1 along the length of the box 1, and can be used to provide driving force for the pontoon and drive the box 1 to move. For example, before the pontoon is spliced, the external power unit 2 is used to drive the pontoon to move, so that the two pontoons can be brought closer to each other, thereby reducing the dependence on auxiliary equipment such as hoisting equipment during splicing, which is conducive to reducing the splicing difficulty of the pontoon and the input of manpower and material resources, and improving the splicing efficiency of the pontoon.

[0036] For example, the pontoon is driven by the external power unit 2 to move as a water vehicle, which can be used to transfer personnel and equipment, thus enriching the pontoon's functions and improving its practicality and flexibility.

[0037] For stable component 3, such as Figure 1 and Figure 3 As shown, the pontoon has at least two stabilizing components 3, which are respectively arranged on opposite sides of the pontoon 1 in the width direction and are symmetrically distributed relative to the pontoon 1 to limit the rolling degree of the pontoon 1. More specifically, when the sea surface is rough, the pontoon is prone to large fluctuations, increasing the rolling degree of the pontoon, which is not conducive to the transfer on the water surface or the implementation of splicing operations. By setting at least two stabilizing components 3 in the width direction of the pontoon 1 and symmetrically distributing them on opposite sides of the pontoon, a rolling damping moment can be formed on opposite sides of the pontoon to resist the waves, reduce the rolling degree of the pontoon when transferring on the water surface, thereby improving the stability of the pontoon on the sea surface and ensuring the smooth progress of offshore operations.

[0038] In some embodiments, the stabilizing component 3 includes a sway-damping fin structure 310, a transmission structure 320, and a drive component 330; wherein, a storage groove 101 is provided on the side wall of the housing 1 for sway-damping fin structure 310 in the recovery condition, that is, the sway-damping fin structure 310 is rotatably disposed relative to the storage groove 101 and can be located in the storage groove 101 in the recovery condition; the transmission structure 320 is disposed inside the housing 1 and connected to the sway-damping fin structure 310; the drive component 330 is disposed inside the housing 1 and connected to the transmission structure 320.

[0039] The application of stabilizing component 3 can improve the stability of the pontoon on the sea surface; such as Figure 1 and Figure 2 As shown, the stabilizing component 3 includes a fin damping structure 310, a transmission structure 320, and a drive component 330. The fin damping structure 310 can generate a damping torque near the water surface during deployment, thereby reducing the degree of swaying of the pontoon on the water surface and improving the stability of the pontoon. During recovery, the fin damping structure 310 can be stored in the storage tank 101 when the wind and waves are small or when two adjacent pontoons are spliced, so as to avoid the deployed fin damping structure 310 interfering with the placement or splicing of the pontoon.

[0040] For the transmission structure 320 and the drive component 330, the transmission structure 320 is disposed inside the housing 1 and connected to the anti-roll fin structure 310; the drive component 330 is disposed inside the housing 1 and connected to the transmission structure 320; as Figure 2 As shown, the drive component 330 can provide driving force to the anti-roll fin structure 310. The driving force output by the drive component 330 drives the anti-roll fin structure 310 to move through the transmission structure 320, so as to drive the anti-roll fin structure 310 to perform deployment or retraction actions.

[0041] For example, the drive component 330 may adopt a drive structure with linear drive function, such as a linear motor or hydraulic rod, which will not be described in detail here.

[0042] In some embodiments, the anti-roll fin structure 310 includes a fin rotating device 311 and a fin 312. The fin rotating device 311 is located in the receiving groove 101 and is fixedly connected to the transmission structure 320, and is rotatably disposed on the side wall of the receiving groove 101. The fin 312 is connected to the fin rotating device 311 through a rotating shaft 3111, and the fin rotating device 311 drives the fin 312 to rotate through the rotating shaft 3111.

[0043] For the anti-roll fin structure 310, such as Figure 2As shown, the storage tank 101 can protect the rotating fin device 311 during the recovery process, preventing the rotating fin device 311 from being bumped during the movement of the float and affecting the adjustment effect of the fin 312, and ensuring that the anti-roll fin structure 310 can be completely recovered into the storage tank 101; at the same time, the fin 312 of the rotating fin device 311 is connected to the rotating fin device 311 through a rotating shaft 3111, and the rotating shaft 3111 drives the fin 312 to rotate in the water, and the rotating fin 312 adjusts the anti-roll torque to cope with different degrees of wind and waves, ensuring the stability of the float.

[0044] In some embodiments, the transmission structure 320 includes a transmission rod 321 and a gear 322; the transmission rod 321 is fixedly connected to the output end of the drive component 330; a rack portion 3211 is provided on the side of the transmission rod 321, and the extending direction of the rack portion 3211 is the same as the moving direction of the transmission rod 321; the gear 322 meshes with the rack portion 3211 and is fixedly connected to the rotating fin device 311 through a connecting shaft 3221.

[0045] For the transmission structure 320, the transmission structure 320 can drive the anti-roll fin structure 310 connected to it to rotate under the drive of the drive component 330, thereby enabling the anti-roll fin structure 310 to smoothly switch between the deployed state and the retracted state; for example, such as Figure 2 As shown, when the piston rod of the drive component 330 extends or retracts, it can drive the transmission rod 321 to move in a straight line, and drive the gear 322 meshing with it to rotate through the rack portion 3211 on the side wall of the transmission rod 321. Since the rotating fin device 311 is rotatably connected to the side wall of the storage groove 101, and the gear 322 and the rotating fin device 311 are fixedly connected through a connecting shaft 3221, the rotating gear 322 can drive the rotating fin device 311 to rotate synchronously, thereby enabling the anti-roll fin structure 310 to switch between the deployed state and the retracted state.

[0046] In some embodiments, the housing 1 is provided with a plurality of assembly slots 102 along its circumference, and a plurality of connection holes 103 are provided through the sidewall of each assembly slot 102.

[0047] like Figure 1 , Figure 4 and Figure 5 As shown, the box 1 has multiple assembly slots 102 along its circumference, and multiple connection holes 103 are provided through the side wall of each assembly slot 102 to provide additional connection positions so that two floats can be spliced ​​together by fasteners such as bolts, or the spliced ​​floats can be reinforced to further improve the strength of the floating components; other auxiliary components can also be added to the box 1 through the connection holes 103 and fasteners such as bolts to enrich the function of the floats.

[0048] In some embodiments, the external power unit 2 is fixedly connected to the housing 1 via a connecting plate 4. The connecting plate 4 includes a first connecting part 410 and a second connecting part 420. The first connecting part 410 is connected to the housing 1 via a connecting hole 103. The bottom of the second connecting part 420 is fixedly connected to the top of the first connecting part 410, and the two are perpendicular to each other. The second connecting part 420 is connected to the external power unit 2.

[0049] When the pontoon needs to be moved, the external power unit 2 can be fixed to the side wall of the pontoon via the connecting plate 4, so that the pontoon has the function of transfer and can be driven to move; such as Figure 1 and Figure 3 As shown, the connecting plate 4 includes a first connecting part 410 and a second connecting part 420 that are perpendicular to each other; wherein, the bottom of the second connecting part 420 is fixedly connected to the top of the first connecting part 410, and can provide corresponding connection positions at different heights so as to connect the connecting plate 4 with fasteners such as bolts, and at the same time improve the fit between the external power unit 2 and the housing 1.

[0050] In some embodiments, the multi-functional floating box further includes a docking plate 510 and a pin 520, wherein the docking plate 510 is connected to the side wall of the box body 1 through a connecting hole 103; a docking part 511 is provided on the side of the docking plate 510 away from the box body 1, and the docking part 511 has a pin hole 512 adapted to the pin 520, and the extending direction of the pin hole 512 is the same as the length direction of the box body 1.

[0051] The mating plate 510 can be used to splice adjacent boxes 1 to form floating platforms or piers and other floating components. The mating plate 510 can be fixed to the side wall of the box 1 by fasteners such as connecting holes 103 and bolts. During the splicing process, the two boxes 1 are brought close to each other so that the mating parts 511 on the mating plates 510 of the two boxes 1 can align with each other. Since the mating parts 511 protrude in the direction away from the box 1, they can be combined when the two boxes 1 are joined together, and operating space can be reserved so that the pin 520 can be inserted into the matching pin hole 512 to complete the splicing of the floating box. The extension direction of the pin hole 512 is the same as the length direction of the box 1, which can ensure the stability of the pin 520 in the pin hole 512 and prevent the pin 520 from falling off and affecting the splicing quality.

[0052] In addition, compared with using bolt fasteners to rigidly connect adjacent pontoons, pontoons connected by mating plates 510 can achieve slight misalignment and deflection, which can reduce the stress generated at the connection of mating plates 510, improve the reliability of the connection between pontoons 1 and the ability to cope with wind and waves.

[0053] In some embodiments, the housing 1 is provided with an inner compartment 104 and an outer compartment 105, which are connected by a first flow channel 106 and a second flow channel 107. In the height direction of the housing 1, the height of the first flow channel 106 is less than the height of the second flow channel 107. The top of the housing 1 is provided with a first control switch 1061 for controlling the on / off state of the first flow channel 106 and a second control switch 1071 for controlling the on / off state of the second flow channel 107.

[0054] For interior compartment 104 and exterior compartment 105, such as Figure 4 As shown, the inner compartment 104 and the outer compartment 105 are located inside the container 1 and can be used to store liquids such as fresh water or fuel, thus combining storage and wave resistance functions. More specifically, when storing liquid, the first flow channel 106 and the second flow channel 107 can be opened by the first control switch 1061 and the second control switch 1071, respectively, connecting the inner compartment 104 and the outer compartment 105. By making the height of the first flow channel 106 less than the height of the second flow channel 107 in the height direction of the container 1, it can be ensured that the liquid flows between the outer compartment 105 and the inner compartment 104 through the first flow channel 106, thereby realizing the storage or output of the liquid. At the same time, the air in the inner compartment 104 can enter the outer compartment 105 through the second flow channel 107, which can maintain the air pressure balance in the container 1 and ensure the smooth transfer of liquid between the inner compartment 104 and the outer compartment 105.

[0055] In some embodiments, the housing 1 is provided with a main flow channel 108 and branch flow channels 109 respectively connected to the main flow channel 108. Both branch flow channels 109 are connected to the outer compartment 105. In the height direction of the housing 1, the port height of one of the two branch flow channels 109 is greater than the port height of the other. The top of the housing 1 is also provided with an adapter 1010 connected to the main flow channel 108, and a third control switch 1081 for controlling the on / off state of the main flow channel 108.

[0056] Among them, since the pontoon has a storage function, in addition to storing liquids normally, its ability to resist wind and waves can be improved by increasing its weight.

[0057] For example, the main flow channel 108 is opened by the third control switch 1081, and the liquid is introduced into the main flow channel 108 by the adapter 1010. The liquid flows into the branch flow channel 109 through the main flow channel 108, and then into the outer compartment 105 through the branch flow channel 109. Since the liquid can flow from the outer compartment 105 into the inner compartment 104 through the first flow channel 106, and the air is discharged from the inner compartment 104 into the outer compartment 105 through the second flow channel 107, the gas can be discharged from the outer compartment 105 through the other main flow channel 108 and the branch flow channel 109, ensuring the air pressure inside and outside the container 1 is balanced, and allowing the liquid to be smoothly input into the container 1. Then, the main flow channel 108 is closed by the third control switch 1081. As liquid is continuously injected into the pontoon, the weight of the pontoon increases and it gradually sinks into the water, thus giving the pontoon good resistance to wind and waves.

[0058] For example, the main flow channel 108 is opened by the third control switch 1081, and gas is filled into the main flow channel 108 by the adapter 1010. The gas is then injected into the branch flow channel 109 through the main flow channel 108, and then into the outer compartment 105 through the branch flow channel 109. Since liquid can flow from the inner compartment 104 into the outer compartment 105 through the first flow channel 106, and air can be injected from the outer compartment 105 into the inner compartment 104 through the second flow channel 107, the air pressure balance in the compartment can be maintained. The liquid in the outer compartment 105 can be extracted through the other main flow channel 108 and the branch flow channel 109, so that the liquid can be smoothly discharged out of the tank 1. As the liquid is continuously discharged, the weight of the float box is continuously reduced and it gradually floats to the surface of the water, so that the float box can be reused.

[0059] It should be noted that water pumps can be used for pumping and filling water, while air pumps can be used for pumping and filling air. After the pontoon sinks, in order to accurately determine the sinking position of the pontoon, a marking buoy can be set on the water surface and the buoy and the pontoon can be connected by ropes to mark the position of the pontoon. This will not be elaborated on here.

[0060] In some embodiments, the multipurpose pontoon also includes a drag-reducing box 6, which is detachably connected to the box body 1, thereby forming a water vehicle; wherein, the drag-reducing box 6 may be provided with an assembly groove 102 and a connection hole 103, so as to enable quick assembly and disassembly of the box body 1 and the drag-reducing box 6 by means of fasteners such as bolts.

[0061] More specifically, such as Figure 1As shown, the top and bottom of the drag-reducing box 6 are respectively provided with a transfer surface 601 and a drag-reducing surface 602. The drag-reducing surface 602 is inclined in the direction away from the box body 1. The transfer surface 601 is located at the top of the drag-reducing box 6 and serves as a connection, facilitating the transfer of personnel, equipment or items to the top of the pontoon via the transfer surface 601, ensuring the transfer effect. The drag-reducing surface 602 located at the bottom of the drag-reducing splicing block can reduce the water resistance of the pontoon when it travels on the water surface, which is beneficial to reducing the energy loss during the movement of the pontoon.

[0062] In some embodiments, the side wall of the float box is further provided with a fastening component 7, which includes a fastening plate 710 and a fastening ring 720. The fastening plate 710 is connected to the side wall of the box body 1 by fasteners, and the fastening ring 720 is rotatably connected to the fastening plate 710.

[0063] like Figure 7 As shown. In practical applications, the tethering ring 720 provides the tethering point, and the rope can be tied to the tethering ring 720. Since the tethering ring 720 is rotatably connected to the tethering plate 710, the tension direction of the rope can be changed, reducing the degree of constraint between the tethering ring 720 and the tethering plate 710, and ensuring the stability of the pontoon after tethering.
