Description

Technical Field

[0001] This utility model relates to the field of marine engineering technology, and in particular to a floating platform for marine operations. Background Technology

[0002] In the field of marine operations, various floating equipment are widely used in resource exploration, energy development, aquaculture, and many other scenarios. However, existing marine floating equipment suffers from numerous thorny problems caused by unreasonable structural design.

[0003] Chinese patent CN119521799A, "A Photovoltaic Structure Applied to the Sea Surface and a Floating Photovoltaic Power Station," employs a conventional array of pontoons to support the photovoltaic panels. This structure is relatively dispersed and simple, exhibiting significant instability in complex sea conditions. In rough seas, the pontoons sway with the waves, making it difficult for the photovoltaic panels to maintain a stable orientation. This not only affects power generation efficiency but can also damage equipment components due to excessive swaying, greatly reducing the safety and reliability of the photovoltaic power station operating at sea. Furthermore, the operating area of ​​this power station is relatively fixed, making it difficult to flexibly adjust the installation position and angle of the photovoltaic panels. It cannot adapt to different light directions and intensities at different times, limiting operational flexibility and hindering the full utilization of solar energy resources. In addition, this floating photovoltaic power station lacks an effective autonomous drive and control structure, relying primarily on external towing vessels for position adjustments at sea. This method is not only inefficient but also difficult to implement in adverse weather conditions, with extremely low precision in direction and speed control. It cannot meet the need for rapid response and position adjustments in changing sea conditions, severely restricting its widespread application and efficient operation in marine operations.

[0004] Similarly, other traditional floating platforms for marine operations generally suffer from similar problems. Simple support structures cause the platform to sway violently in wind and waves, threatening operational safety; fixed operating areas and a lack of adjustable components limit the placement and operation space of the equipment, making it unable to adapt to diverse operational needs; the absence or inefficiency of drive and control structures means the platform's movement relies on external forces, and its directional and speed control precision is poor, failing to respond promptly to adjustments in the operational position. Therefore, the development of a stable, flexible, and autonomously maneuverable floating platform for marine operations is urgently needed. Utility Model Content

[0030] Example 1

[0031] Please see Figure 1 This utility model provides a floating platform for marine operations. The sea surface lacks a fixed support surface and is affected by wind, waves, tides, and other factors, making the operating environment complex and unstable, and traditional land-based equipment difficult to apply directly. The marine operation platform provides buoyancy through floating pods and enhances stability through a supporting structure, providing a relatively stable foundation for operations. This solves the core pain points of "no fixed operating surface" and "large environmental fluctuations," while integrating operating space and mobility to meet the specific needs of marine operations.

[0032] For example, during seabed mineral and oil and gas resource exploration, the platform can carry geological detectors, sampling equipment, etc. Staff can operate the instruments on the stable platform to complete seabed data collection, sample extraction and other tasks, avoiding the impact of ship swaying on the detection accuracy.

[0033] For applications such as offshore wind power base installation and submarine cable laying, the platform can hold construction tools and components. The sliding work section can flexibly adjust the position of the equipment and move it to the construction site in conjunction with the drive mechanism, providing a close-range operating platform for construction personnel.

[0034] Please see Figure 1 , Figure 3 and Figure 5 In this embodiment, the floating platform includes a floating pod 100, a first support frame 200, a working platform 260, and a drive mechanism 300. The floating pod 100 is hollow and can float on the sea surface. The first support frame 200 is disposed inside the floating pod 100 and includes a rod portion 210 and a support portion 220 disposed at the bottom of the rod portion 210. The rod portion 210 includes a plurality of parallel support rods 211 and a plurality of connecting rods 212 connecting the plurality of support rods 211. The bottom of the support rods 211 is also provided with support legs 221. The working platform 260 includes a first mounting frame 261 and a first bearing plate 262 disposed on the top of the first mounting frame 261. The drive mechanism 300 is disposed at one end of the floating pod 100 and is used to drive the floating pod 100 to move.

[0035] The hollow buoyancy 100 is the core of the platform's buoyancy, enabling the entire platform to float stably on the sea surface, thus solving the fundamental problem of not having a fixed working surface. Even when the sea surface fluctuates due to wind and waves, its closed hollow structure can provide continuous buoyancy, providing a basic support for the equipment and personnel on the platform, and supporting the overall floating requirements of the platform when operating in various sea areas.

[0036] Please see Figure 1 and Figure 5 The first support frame 200, located within the floating pod 100, is the core component ensuring stability. Several parallel support rods 211 of the rod section 210 are connected by connecting rods 212 to form a rigid frame structure, enhancing the overall structural strength of the platform. The bottom support legs 221 and the support rods 211 form a triangular support structure, distributing the platform's weight and operational loads across the floating pod 100, reducing platform swaying caused by uneven stress in wind and waves, and significantly improving platform stability under conditions of large environmental fluctuations. This structure ensures the platform remains stable during equipment operation and personnel handling, preventing swaying from affecting operational accuracy.

[0037] Please see Figure 2 and Figure 3 The work platform 260, consisting of a first mounting frame 261 and a first support plate 262, provides dedicated operating space for offshore operations. The first support plate 262 can support various work equipment such as geological survey instruments and construction tools, while the first mounting frame 261 provides stable support for the support plate, ensuring that the equipment is not easily displaced when the platform shakes. This structure meets the operational needs of equipment placement and personnel operation, facilitating data acquisition, equipment installation, and other tasks.

[0038] The drive mechanism 300, located at one end of the floating pod 100, is the core of the platform's movement, driving the floating pod 100 to move on the sea surface and freeing the platform from dependence on external towing. Under the influence of wind and waves, the platform's position can be adjusted via the drive mechanism 300 to ensure precise arrival at the work site, facilitating flexible switching between different work areas and completing mobile work tasks.

[0039] Taking seabed oil and gas exploration as an example, this platform plays a significant role in near-shore exploration areas with turbulent waves. The floating pod 100, with its hollow structure, provides ample buoyancy, allowing the platform to float stably on the surface of the exploration site and resist the undulating effects of wind and waves. The support rods 211 and connecting rods 212 of the first support frame 200 form a robust framework, while the triangular structure of the support legs 221 further reduces platform sway, ensuring the stability of the geological detectors and sampling equipment mounted on the first bearing plate 262 of the work platform 260. Standing on the bearing plate, personnel can smoothly operate the equipment to transmit detection signals to the seabed and lower samplers, avoiding deviations in detection data or sampler position shifts due to platform sway. When it is necessary to move to the next exploration site, the drive mechanism 300 is activated, moving the platform on the sea surface without waiting for external vessels to tow it, efficiently completing exploration operations at different locations and significantly improving the efficiency and accuracy of seabed oil and gas exploration.

[0040] Further, please see Figure 5 The first support frame 200 is further provided with a second support frame 231 and a third support frame 232 at intervals on both sides; the second support frame 231 and the third support frame 232 are respectively provided with a second bearing plate 233 and a third bearing plate 234; the second bearing plate 233 and the third bearing plate 234 are both provided with a gap between them and the first bearing plate 262.

[0041] Further, please see Figure 3 and Figure 4 The top of the first support plate 262 is also provided with a first sliding working part 240 and a second sliding working part 250; the first sliding working part 240 and the second sliding working part 250 are respectively disposed at both ends of the first support frame 200.

[0042] Furthermore, the first sliding work unit 240 includes a first slide block 241 and a second slide block 242 disposed on both sides of the end of the first support frame 200, and a first work rod 245 that moves based on the first slide block 241 and the second slide block 242 via a first slider 243 and a second slider 244; the first sliding work unit 240 and the second sliding work unit 250 have the same structural configuration.

[0043] Furthermore, the first working rod 245 is connected to the first slider 243 and the second slider 244 via a first connecting frame 246; the first connecting frame 246 includes a first frame body 247 and a first connecting block 248 and a second connecting block 249 disposed on both sides of the first frame body 247; the two ends of the first working rod 245 are respectively hinged to the first connecting block 248 and the second connecting block 249; the first connecting block 248 and the second connecting block 249 can be displaced in the interval between the first support frame 200, the second support frame 231, and the third support frame 232.

[0044] Further, please see Figure 5 The support leg 221 at the bottom of the support rod 211 includes a first support leg and a second support leg; the first support leg, the second support leg and the support rod 211 form a triangular support structure.

[0045] The second sliding working part 250 includes a third slide block 251 and a fourth slide block 252 disposed on both sides of the end of the first support frame 200, and a second working rod 255 that moves based on the third slide block 251 and the fourth slide block 252 via a third slider 253 and a fourth slider 254.

[0046] Further, please see Figure 3 The second working rod 255 is connected to the third slider 253 and the fourth slider 254 via a second connecting frame 256; the second connecting frame 256 includes a second frame body 257 and a third connecting block and a fourth connecting block disposed on both sides of the second frame body 257; the two ends of the second working rod 255 are respectively hinged to the third connecting block and the fourth connecting block; the third connecting block and the fourth connecting block can be displaced in the interval between the first support frame 200 and the second support frame 231 and the third support frame 232.

[0047] The first sliding working unit 240 and the second sliding working unit 250 can achieve linear displacement along the sliding base, breaking the limitations of traditional fixed working areas. The working rod can drive the equipment installed on it (such as exploration probes, construction clamps, sampling devices, etc.) to move flexibly within the space between the first bearing plate 262, the second bearing plate 233, and the third bearing plate 234, covering a larger working radius, which is especially suitable for scenarios that require precise alignment (such as position calibration during the installation of seabed equipment and multi-point sampling during sample collection).

[0048] The modular design of the sliding working part is compatible with different types of working tools; through the hinge structure of the first connecting frame 246 and the second connecting frame 256, the working rod can rotate within a certain angle, and in conjunction with the sliding displacement, it can achieve a composite motion of translation and angle adjustment, which can not only meet the stable fixing requirements of heavy equipment, but also adapt to the fine operation of light instruments (such as multi-depth deployment of water quality sensors and precise docking of cable connectors).

[0049] The sliding block and the slider are designed with a rigid connection, which can maintain the positional accuracy of the working rod even when the platform shakes slightly due to waves. At the same time, the displacement of the first connecting block 248 and the second connecting block 249 in the support frame interval is restricted, which avoids equipment collision caused by excessive sliding and ensures operation safety.

[0050] When the working position needs to be changed, the first working rod 245 or the second working rod 255 is moved by sliding the drive sliders (first slider 243, second slider 244, third slider 253, fourth slider 254) along the tracks of the corresponding slides (first slide 241, second slide 242, third slide 251, fourth slide 252).

[0051] For example, in submarine cable laying operations, if it is necessary to adjust the position of the cable laying port, the third slider 253 and the fourth slider 254 can be driven to move along the third slide block 251 and the fourth slide block 252, so that the second working rod 255 can drive the laying device to move laterally to the target position.

[0052] The hinged structure between the working rod and the connecting block allows the working rod to rotate around the hinge point, enabling fine-tuning of the angle. For example, when installing offshore wind turbine base components, by rotating the first working rod 245 to make it 30° to the horizontal, it can be adapted to the inclined mounting surface of the component, and then the fastening operation is completed by fixing the position with the slider.

[0053] Sliding and angle adjustment can be performed simultaneously: In geological sampling operations, the first working rod 245 is first moved to directly above the sampling point by sliding the first slider 243 and the second slider 244, and then the working rod is rotated to tilt the sampler at its end by 45° to conform to the seabed topography and complete the sampling, thereby improving the efficiency of operation.

[0054] For example, let's take the tightening of bolts on offshore wind turbine foundations as an example:

[0055] The platform moves to the vicinity of the wind turbine base via the drive mechanism 300. The triangular support structure of the first support frame 200, the second support frame 231, and the third support frame 232 ensures the stability of the platform.

[0056] Fix a fastening tool (such as a hydraulic wrench) to the end of the first working rod 245, drive the first slider 243 and the second slider 244 to slide along the first slide block 241 and the second slide block 242, so that the tool is moved to the front of the bolt;

[0057] Rotate the first working lever 245 (via the hinge between the first connecting block 248 and the second connecting block 249) to adjust the contact angle between the wrench and the bolt, ensuring precise alignment. After tightening, slide the slider in the opposite direction to reset the working lever. Then, the second working lever 255 of the second sliding working part 250 carries the tool of the next specification, repeating the above steps to tighten other bolts. Through this combined sliding and hinge adjustment, multi-position and multi-angle operations can be efficiently completed under complex sea conditions, significantly reducing the difficulty of manual operation.

[0058] Further, please see Figure 6 The drive mechanism 300 includes a second mounting bracket 310 and a control shaft 333 that can rotate based on the second mounting bracket 310; the two ends of the control shaft 333 are respectively provided with a control part 340 and a drive part 360; the drive mechanism 300 is disposed at one end of the float 100 through the second mounting bracket 310.

[0059] Furthermore, the control unit 340 includes a control compartment 341 and a circuit board and a power supply battery disposed within the control compartment 341. The control circuitry within the control compartment 341 is connected to the drive unit 360 via the control shaft 333. A control handle 352 is also provided at the end of the control compartment 341.

[0060] Furthermore, the second mounting bracket 310 includes a clamping part 320 that is clamped on the float 100 and is arranged in a "U" shape, and a rotating part 330 that is provided with a first rotating head 331 and a second rotating head 332; the control shaft 333 is disposed in the first rotating head 331 and the second rotating head 332 and can rotate based on the first rotating head 331 and the second rotating head 332.

[0061] Furthermore, the drive unit 360 includes a rotating head 361 driven by the control unit 340 and a fan blade 362 that is pulsatorically connected to the rotating head 361; the end of the rotating head 361 is provided with a flow guide shroud 363.

[0062] This drive mechanism 300 achieves precise driving and flexible control of the floating platform at sea through the collaborative design of multiple components. The core of the drive mechanism 300 is to realize the movement of the platform through the control-transmission-drive link: the power supply battery of the control unit 340 provides energy for the entire mechanism, the circuit board in the control compartment 341 receives start or stop commands and transmits electrical signals to the drive unit 360 through the lines inside the control shaft 333.

[0063] The rotating head 361 of the drive unit 360 is started under the action of the control signal, which drives the fan blade 362 to rotate at high speed. The fan blade 362 cuts the water flow and generates a reaction force, forming a thrust that propels the platform to move. The guide shroud 363 at the end of the rotating head 361 guides the water flow to flow smoothly over the fan blade 362, reducing the loss of thrust due to water flow turbulence and improving propulsion efficiency.

[0064] The control shaft 333 can rotate based on the first rotating head 331 and the second rotating head 332, causing the drive unit 360 to change its overall angle (such as upward, downward, or left and right deflection), thereby adjusting the direction of the thrust of the fan blades 362 and realizing the platform's steering, lifting, or lateral movement. For example, when the platform needs to turn to the left, the control shaft 333 drives the drive unit 360 to deflect to the left, and the thrust generated by the fan blades 362 forms a lateral component force, guiding the platform to turn.

[0065] Furthermore, by operating the circuit board of the control unit 340 through the control handle 352, the current of the input drive unit 360 can be changed, thereby adjusting the rotation speed of the rotating head 361 and the fan blade 362: when the rotation speed increases, the thrust increases and the platform accelerates; when the rotation speed decreases, the thrust decreases and the platform decelerates, thus achieving linear speed control.

[0066] When the platform tilts slightly due to wind and waves, the rotation of the control shaft 333 can adjust the angle of the drive unit 360 in accordance with the platform's posture, ensuring that the fan blade 362 always cuts the water flow at a better angle and maintains propulsion efficiency (for example, when the platform tilts forward, the drive unit 360 is adjusted downward slightly to prevent the fan blade 362 from being exposed above the water surface).

[0067] The "U"-shaped clamping part 320 of the second mounting bracket 310 is firmly fixed to the end of the float 100, providing stable support for the entire drive mechanism 300; the first rotating head 331 and the second rotating head 332 of the rotating part 330 provide rotation fulcrum for the control shaft 333, ensuring stable transmission process.

[0068] In this embodiment, the control unit 340 and the drive unit 360 are directly connected through the internal wiring of the control shaft 333, resulting in low signal transmission delay. Combined with the operation of the control handle 352, the platform speed and direction can be adjusted in real time, which is especially suitable for operations that require precise alignment (such as fine-tuning when approaching a wind turbine base or exploration point).

[0069] The flow guide 363 reduces the impact and interference of water flow on the fan blades 362, and can maintain propulsion stability even in the event of surges; the firm fixation of the "U" shaped clamping part 320 prevents the drive mechanism 300 from loosening during bumps and improves the mechanism's resistance to wind and waves.

[0070] The design of this 300 drive mechanism not only meets the needs of offshore operations for platform mobility, but also ensures reliability in complex environments through structural optimization, providing core power support for the platform's efficient operation.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
