Description

Technical Field

[0003] Patent document CN2806299Y discloses a combined floating platform with adjustable water level. By setting a water inlet at the lower end of the floating platform to connect the inside of the platform, and controlling the water volume by using a pump, the draft of the floating platform can be adjusted to meet the needs of floating platform facilities for different purposes.

[0004] Patent document US6564741B2 discloses a telescopic pontoon platform and its usage method, comprising a telescopic pontoon structure that achieves telescopic functionality through multiple nested tubes, used to support various marine observation and energy production equipment. The platform is compact in design, easy to deploy and recover, and suitable for a wide range of applications from small buoys to large marine platforms.

[0005] While these devices possess some draft adjustment capabilities, they cannot dynamically adjust their attitude based on the real-time flow velocity and direction of ocean and inland waters. This can lead to instability phenomena such as lateral drift, thereby affecting the stability of detection or operations. Utility Model Content

[0033] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0034] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it will not be further defined and explained in subsequent figures.

Therefore, they should not be construed as limitations on this utility model.

[0036] like Figure 1-3As shown, this embodiment provides a float-type underwater operation device with adaptive flow velocity and direction, including a float 1, an adjustment head 2, a telescopic structure 3, multiple stabilizing wings 4, and a control unit.

[0037] like Figure 1-2 As shown, the float 1 has a sealed air chamber inside, which provides a constant buoyancy source for the equipment, ensuring that positive buoyancy is maintained regardless of load increases or decreases. The upper end of the float 1 has a construction area 101, which is used to set up functional units 102, which can be configured to perform functions such as communication, detection, and photography as needed.

[0038] like Figure 1 , 3 As shown, the adjusting head 2 is located at the lower end of the float 1. The telescopic structure 3 connects the float 1 and the adjusting head 2, and is used to adjust the relative distance between the adjusting head 2 and the float 1 to change the overall center of gravity of the equipment, thereby achieving longitudinal attitude adjustment. Stabilizing fins 4 are set on the outer periphery of the float 1, and the angle of each stabilizing fin 4 relative to the corresponding tangential plane of the float 1 is adjustable, thereby generating a controllable force component in the horizontal plane to counteract the yaw moment caused by the lateral flow velocity. The equipment is equipped with a control unit, which is used to control the telescopic amount of the telescopic structure 3 and the angle of each stabilizing fin 4.

[0039] It should be noted that the telescopic structure 3 is driven by the first drive mechanism, and each stabilizing wing 4 is driven by the second drive mechanism. The control unit collects data such as flow velocity, flow direction, and attitude angle in real time, and controls the operation of the first and second drive mechanisms based on the equipment attitude information and environmental change information to adjust the telescopic amount of the telescopic structure 3 and the angle of each stabilizing wing 4 relative to the corresponding position tangent of the float 1. Preferably, the second drive mechanism is a motor, and the motor controls the angle change of the stabilizing wing 4 through a gear assembly.

[0040] like Figure 1 As shown, the stabilizing wing 4 has a symmetrical structure, with inclined sides on both the upper and lower sides. The inclined sides converge towards the middle and intersect with the outer edge, thereby maintaining the stability of the wing.

[0041] like Figure 1-3 As shown, the float 1 comprises multiple interconnected cylindrical sections, with the stabilizing wing 4 positioned on the outer periphery of the final stage cylindrical section of the float 1, near the telescopic structure 3 and the adjusting head 2. The multi-section interconnected cylindrical float 1 can be lengthened or reduced by disassembly and reassembly, thereby linearly adjusting the displacement and buoyancy reserve. The stabilizing wing 4 is only arranged on the outer periphery of the final stage cylindrical section near the telescopic structure 3 and the adjusting head 2, ensuring that the stabilizing wing 4 is always in the most stable assembly area.

[0042] like Figure 2 , 4As shown, the adjusting head 2 includes a main housing 5, and the telescopic structure 3 includes a vertical steel belt 31 and a drive belt 32. The vertical steel belt 31 has intermittently distributed meshing holes. The drive belt 32 is perpendicular to the vertical steel belt 31 and has a toothed structure on its edge. The vertical steel belt 31 meshes with the drive belt 32, and the free end of the vertical steel belt 31 is connected to the lower end of the float 1. Under the action of the drive belt 32, the vertical steel belt 31 extends spirally out of the main housing 5 and connects with each other layer by layer to form a cylindrical shape, thereby increasing the distance between the float 1 and the adjusting head 2.

[0043] It should be understood that the main shell 5 provides sealing and support for the telescopic mechanism, and includes a vertical steel belt 31, a drive belt 32, a first drive mechanism for rotating the drive belt 32, and a guide mechanism for engaging and lifting the drive belt 32 with the vertical steel belt 31. The drive belt 32 utilizes high longitudinal stiffness to transmit thrust, and the vertical steel belts 31 interlock to form a self-supporting cylinder, maintaining structural strength during telescopic movement. The entire structure enables the axial adjustment of the center of gravity of the float-type underwater operating equipment.

[0044] like Figure 3-5 As shown, the vertical steel strip 31 may still vibrate due to lateral flow impact when extended, thus requiring additional protective measures. A cylindrical rigid stabilizing sleeve 6 is provided below the float 1, and the upper section of the spirally extended cylindrical vertical steel strip 31 is located within the stabilizing sleeve 6. The stabilizing sleeve 6 provides radial restraint for the upper section of the steel strip, and its rigidity also buffers lateral impacts, acting as a "crash cage" in the event of an accidental lateral collision, preventing localized plastic deformation of the steel strip from causing extension and contraction jamming.

[0045] like Figure 5 As shown, the stabilizing sleeve 6 is provided with multiple flow stabilizing holes 7, through which liquid can enter the enclosed area of ​​the stabilizing sleeve 6. The flow stabilizing holes 7 enable communication between the water inside the sleeve and the external flow field, preventing the formation of closed cavity vortices inside the sleeve; at the same time, they can reduce the lateral flow velocity, playing a damping role, thereby further improving the stability of the equipment.

[0046] like Figure 1-5 As shown, the adjusting head 2 includes a protective cover 8, which is fitted over the main housing 5. A buffer gap is provided between the protective cover 8 and the main housing 5 to absorb impact energy. The protective cover 8 has multiple drainage holes 9 to achieve rapid drainage. The protective cover 8 includes a cylindrical section 81 and an inverted truncated cone section 82. The inverted truncated cone section is more conducive to its water entry operation.

[0047] like Figure 1As shown, the float 1 and the adjusting head 2 are connected by an adjustable-length rope 10. The adjustable-length rope 10 is added between the float 1 and the adjusting head 2 as a mechanical redundancy backup. The rope 10 can help share the load, and when the telescopic structure 3 malfunctions or loses power, the rope 10 can be manually or automatically locked to prevent the adjusting head 2 from falling freely, thus improving system safety.

[0048] like Figure 1-3 As shown, multiple pulley assemblies 11 are evenly distributed along the edge of the upper end face of the adjusting head 2, i.e. the upper end face of the protective cover 8. The pulley assembly 11 includes a pulley frame 12 and a pulley 13 to form a low-friction guide, realizing the reversal of the rope 10. The lower end of the float 1 is provided with a paired rope loop 14. The rope 10 connecting the adjusting head 2 and the float 1 passes through the pulley 13 and the rope loop 14, so that the rope 10 is always subjected to force in the tangential direction, reducing lateral bending. The length of the rope 10 changes with the distance between the float 1 and the adjusting head 2.

The descriptions of these embodiments are merely for the purpose of aiding understanding of this invention and its core concepts. It should be noted that those skilled in the art can make various improvements and modifications to this invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this invention.
