Description

Technical Field

[0001] This invention relates to the field of marine photovoltaic construction technology, specifically to the design of a floating self-climbing construction platform. Background Technology

[0002] Given the current increasing energy shortage, key energy development strategies emphasize the need to advance a revolution in energy production and consumption, and to build a safe and efficient energy system. Offshore solar power, as a clean and efficient energy utilization method, possesses enormous development potential and commercial value against the backdrop of global energy transition and climate change mitigation. With increased policy support, in-depth technological research and development, and the improvement of industry standards, offshore solar power is expected to become an important component of the future energy structure.

[0003] However, marine photovoltaics is still in its early stages, facing significant construction challenges, limited available experience, and a shortage of specialized equipment. For example, the lack of offshore construction platforms hinders welding due to the absence of a stable point of contact and compromises weld quality. Furthermore, the absence of maintenance and touch-up platforms necessitates the development of a floating, self-climbing construction platform that integrates floating transportation, rapid installation, autonomous climbing, circumferential operation, and construction protection to address the existing technical limitations. Summary of the Invention

[0004] To address the issues of a lack of stable working platforms around offshore support components, insufficient leverage points for welding and maintenance operations, and difficulty in ensuring construction quality and safety, a specialized construction platform is proposed that can be floated and transported, opened and closed for installation, self-climbing and positioning, and can operate in a circumferential manner. This platform aims to solve the problems of a lack of stable working platforms, limited operating space for personnel, significant impact from wind and waves, low construction efficiency, and high safety risks in the construction of existing offshore photovoltaic and pile components.

[0005] To achieve the above objectives, the present invention provides a floating self-climbing construction platform, including a connecting frame module, a clamping module, a climbing module, and a working platform module disposed on the connecting frame module. The clamping module is connected to the component to be climbed and is used to clamp and connect the component to be climbed. The climbing module is connected to the clamping module, and the working platform module is connected to the climbing module. The continuous climbing or lowering of the component to be climbed and the working platform module is achieved by the alternating clamping of the clamping module and the climbing module and the extension and retraction of the climbing module.

[0006] Furthermore, the connecting frame module includes a first connecting frame and a second connecting frame, which are arranged symmetrically at the top and bottom and connected by a climbing module. Clamping modules are provided on the first and second frames.

[0007] Furthermore, the clamping module includes a first clamping unit, a second clamping unit, a third clamping unit, and a fourth clamping unit. The first clamping unit and the second clamping unit are arranged vertically at intervals and are installed on the first side of the connecting frame module. The first clamping unit is installed on the first connecting frame, and the second clamping unit is installed on the second connecting frame, for clamping or releasing the component to be climbed from the first direction. The second clamping unit and the fourth clamping unit are arranged vertically at intervals and are mounted on the second side connecting frame module opposite to the first side. The third clamping unit is mounted on the first connecting frame and the fourth clamping unit is mounted on the second connecting frame, and are used to clamp or release the climbing component from the second direction opposite to the first direction.

[0008] Furthermore, the climbing module includes a first climbing unit and a second climbing unit. The first climbing unit and the second climbing unit are respectively disposed opposite to each other between the connecting frame modules on the third side and the fourth side. The upper ends of the first climbing unit and the second climbing unit are respectively connected to the first connecting frame of the first clamping unit and the third clamping unit, and the lower ends are respectively connected to the second connecting frame of the second clamping unit and the fourth clamping unit, thereby forming a square clamping climbing structure surrounding the component to be climbed. The first clamping unit and the third clamping unit first clamp the upper part of the component to be climbed, the second clamping unit and the fourth clamping unit relax, and then the first climbing unit and the second climbing unit retract synchronously. Since the first clamping unit and the third clamping unit are in a clamped and fixed state, the first connecting frame is also in a fixed state, and the reaction force pulls the second connecting frame upward. Then, the first and third clamping units are released, and the second and fourth clamping units are clamped on the lower part of the component to be climbed. Then, the first and second climbing units are stretched synchronously. Since the second and fourth clamping units are in a clamped and fixed state, the second connecting frame is also in a fixed state, and the reaction force pushes the first connecting frame upward.

[0009] Furthermore, the working platform module includes a platform unit, a platform opening and closing unit, and a platform opening and closing drive unit. The platform opening and closing unit is connected to the platform unit through the platform opening and closing drive unit to form a ring platform together.

[0010] Furthermore, the platform unit has an overall U-shaped plate structure, which is fixed around the clamping module and the climbing module, and is connected to the three sides of the frame module. When the connecting frame module moves upward, it drives the platform unit to climb upward.

[0011] Furthermore, the platform opening and closing unit is shaped to match the "U"-shaped opening of the platform unit. The platform opening and closing unit includes a first opening and closing component and a second opening and closing component. The first opening and closing component and the second opening and closing component are respectively disposed on both sides of the "U"-shaped opening of the platform unit and are connected to the platform unit through a platform opening and closing drive unit. The platform opening and closing drive unit is used to realize the closing and opening of the first opening and closing component and the second opening and closing component.

[0012] Furthermore, the platform opening and closing drive unit includes a drive component and a slider component. The drive component is disposed on the platform unit and is connected to the slider component. The slider component includes a slider and a slide rail. The slider is respectively disposed below the first opening and closing component and the second opening and closing component. The slide rail is disposed on the platform unit. By driving the slider to reciprocate along the slide rail through the drive component, the first opening and closing component and the second opening and closing component can be precisely closed and opened. When closed, the platform opening and closing unit is seamlessly connected to the platform unit to form a complete "U"-shaped annular platform.

[0013] Furthermore, a platform windproof enclosure unit is provided along the outer edge of the platform unit and the platform opening and closing unit. The platform windproof enclosure unit includes several columns and windbreaks. The several columns are vertically arranged along the outer edge of the platform unit and the platform opening and closing unit, and the windbreaks are fixed between the columns to form circumferential protection.

[0014] Furthermore, the platform unit and the platform opening and closing unit are provided with a platform buoyancy unit at the bottom, so that the overall structure of the platform unit and the platform opening and closing unit can float on the water surface.

[0015] The floating self-climbing construction platform provided by this invention has a clear structural module and a well-defined installation and usage process. It can adapt to the construction and maintenance needs of offshore photovoltaic piles, support columns and similar vertical components, effectively overcoming the problems existing in the prior art.

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to specific illustrations.

[0020] To address the issues of a lack of stable working platforms around offshore support components, insufficient leverage points for welding and maintenance operations, and difficulties in ensuring construction quality and safety, a specialized construction platform is proposed that can be floated and transported, installed by opening and closing, self-climbing and positioned, and can operate in a circumferential manner. The device has a clear structural module and a well-defined installation and usage process, and can adapt to the construction and maintenance needs of offshore photovoltaic piles, support columns, and similar vertical components, effectively overcoming the problems existing in the current technology.

[0021] The floating self-climbing construction platform provided by the present invention includes a connecting frame module, a clamping module, a climbing module, and a working platform module.

[0022] The clamping module is connected to the component to be climbed and is used to clamp and connect the component to be climbed.

[0023] The climbing module is connected to the clamping module, and the working platform module is connected to the climbing module. The continuous climbing or lowering of the component to be climbed and the working platform module is achieved through the alternating clamping of the clamping module and the extension and retraction of the climbing module.

[0024] For details, see Figures 1-3 The connection frame module includes a first connection frame 11 and a second connection frame 12. The first frame 11 and the second frame 12 are arranged symmetrically at the top and bottom, and are connected to each other through a climbing module.

[0025] This solution does not limit the structure of the first connecting frame 11 and the second connecting frame 12; the specific structure can be determined according to the actual situation.

[0026] Furthermore, the clamping module includes a first clamping unit 21, a second clamping unit 22, a third clamping unit 23, and a fourth clamping unit 24. The first clamping unit 21 and the second clamping unit 22 are respectively disposed at the upper and lower ends of the first side of the connecting frame module, and the third clamping unit 23 and the fourth clamping unit 24 are respectively disposed at the upper and lower ends of the second side of the connecting frame module opposite to the first clamping unit 21 and the second clamping unit 22, forming an opposing clamping with the first clamping unit 21 and the second clamping unit 22.

[0027] Specifically, the first clamping unit 21 and the second clamping unit 22 are arranged vertically at intervals and installed on the first side of the connecting frame module. The first clamping unit 21 is installed on the first connecting frame 11 and the second clamping unit 22 is installed on the second connecting frame 12, and is used to clamp or release the climbing component 5 from the first direction.

[0028] The third clamping unit 23 and the fourth clamping unit 24 are arranged vertically at intervals and are installed on the second side connecting frame module opposite to the first side. The third clamping unit 23 is installed on the first connecting frame 11 and the fourth clamping unit 24 is installed on the second connecting frame 12. They are used to clamp or release the climbing component 5 from the second direction opposite to the first direction.

[0029] The first clamping unit 21, the second clamping unit 22, the third clamping unit 23 and the fourth clamping unit 24 in this solution have the same structure, which are respectively composed of a clamping drive assembly, a clamping arm and a friction pad.

[0030] In this solution, the clamping drive component is implemented by using a hydraulic cylinder as the clamping drive component. The cylinder body of the hydraulic cylinder is fixed on the connecting frame, and the end of its piston rod is connected to the clamping arm. The clamping arm clamps and releases the climbing component by driving the extension and retraction of the piston rod through the hydraulic cylinder.

[0031] The clamping arm is located at the end of the piston rod of the clamping drive assembly. Both ends of the clamping arm are designed with guide ramps to securely clamp the climbing component. For example, the clamping arm can be an arc-shaped or V-shaped clamping arm.

[0032] Meanwhile, friction pads are installed on the inner side of the gripping arm to increase the friction of the contact surface, improve the gripping force, and prevent slippage.

[0033] It should be noted that the first clamping unit 21 and the second clamping unit 22 in this solution are detachably connected to the first connecting frame 11 and the second connecting frame 12. This solution does not limit the detachable structure; the specific configuration can be determined according to the actual situation. (See [reference]). Figure 4 In this solution, the first clamping unit 21 and the second clamping unit 22 are detachably connected by setting a spring buckle 25.

[0034] The climbing module includes a first climbing unit 31 and a second climbing unit 32. The first climbing unit 31 and the second climbing unit 32 are respectively disposed opposite to each other between the connecting frames on the third side and the fourth side. The upper ends of the first climbing unit 31 and the second climbing unit 32 are respectively connected to the first connecting frame 11 of the first clamping unit 21 and the third clamping unit 3, and the lower ends are respectively connected to the second connecting frame 12 of the second clamping unit 22 and the fourth clamping unit 24, thereby forming a square-shaped clamping and climbing structure surrounding the component to be climbed.

[0035] This solution does not limit the structure of the climbing module. Specifically, it can be described as an electrically or hydraulically driven jack, which is used to realize the extension and retraction climbing action of the climbing module.

[0036] First, the first clamping unit 21 and the third clamping unit 23 clamp the upper part of the component 5 to be climbed. The second clamping unit 22 and the fourth clamping unit 24 are released. Then, the first climbing unit 31 and the second climbing unit 32 retract synchronously. Since the first clamping unit 21 and the third clamping unit 23 are in a clamped and fixed state, the first connecting frame 11 is also in a fixed state. The reaction force pulls the second connecting frame 12 upward.

[0037] Then, the first clamping unit 21 and the third clamping unit 23 are released, and the third clamping unit 23 and the fourth clamping unit 24 are clamped to the lower part of the component to be climbed. Then, the first climbing unit 31 and the second climbing unit 32 are stretched synchronously. Since the third clamping unit 23 and the fourth clamping unit 24 are in a clamped and fixed state, the second connecting frame 12 is also in a fixed state, and the reaction force pushes the first connecting frame 11 upward.

[0038] Thus, this cycle of "clamping-extending-changing-clamping-retracting" enables the platform to climb autonomously along the components like an inchworm, and at any given time, at least one clamping unit will rigidly lock the platform to the components, fundamentally ensuring safety.

[0039] Secondly, after climbing to the designated working height, the first clamping unit 21, the second clamping unit 22, the third clamping unit 23, and the fourth clamping unit 24 can simultaneously clamp the component 5 to be climbed, so that the platform is stably fixed in the working position, providing reliable support for welding, installation, inspection, maintenance, and painting of the offshore photovoltaic support components, and improving the construction conditions at sea where there is no fixed working surface.

[0040] The working platform module includes a platform unit 41, a platform opening and closing unit 42, a platform opening and closing drive unit 43, a platform windproof enclosure unit 44, and a platform buoyancy unit 45. The platform opening and closing unit 42 is connected to the platform unit 41 through the platform opening and closing drive unit 43, together forming a return platform.

[0041] The platform unit 41 has an overall U-shaped plate structure, which is fixed around the clamping module and the climbing module, and is connected to three sides of the second connecting frame 12 in the frame module. When the second connecting frame 12 moves upward, it drives the platform unit 41 to climb upward. Its opening direction is consistent with the mounting side of the first clamping unit 21 and the second clamping unit 22. The platform unit 41 includes a main platform plate, a main frame, a kick plate, a guardrail base, and a guide rail mounting seat.

[0042] The main platform plate is a U-shaped integral structure made up of multiple steel plates. The main frame is connected to the main platform plate to increase the load-bearing capacity of the main platform plate to support its own weight and personnel load.

[0043] A kick plate can be installed along the outer edge of the main platform plate and the edge of the inner hole to prevent tools or debris from falling.

[0044] Several sleeves are installed at equal intervals on the outer edge of the main platform plate for inserting the columns of the windproof enclosure.

[0045] Guide rail mounting bases are provided below the two sides of the "U"-shaped opening for setting the platform opening and closing drive unit 43.

[0046] The platform opening and closing unit 42 is shaped to match the "U"-shaped opening of the platform unit 41. The platform opening and closing unit 42 includes a first opening and closing component and a second opening and closing component. The first opening and closing component and the second opening and closing component are respectively disposed on both sides of the "U"-shaped opening of the platform unit and are connected to the platform unit through the platform opening and closing drive unit 43. The platform opening and closing drive unit 43 realizes the closing and opening of the first opening and closing component and the second opening and closing component.

[0047] The platform opening and closing drive unit 43 includes a drive component and a slider component. The drive component is disposed on the platform unit and its drive is connected to the slider component.

[0048] The composition of the drive components is not limited in this solution. For example, it can be a servo motor, but the specific components can be determined according to the actual situation.

[0049] The slider assembly includes a slider and a slide rail. The slider is respectively located below the first and second opening / closing components. The slide rail is located in the guide rail mounting seats below the two sides of the "U"-shaped opening of the platform unit 41. The slider is driven by the drive component to reciprocate along the slide rail, thereby enabling the first and second opening / closing components to precisely close and open. When closed, the platform opening / closing unit 42 and the platform unit 41 are seamlessly connected to form a complete "U"-shaped circular platform. Construction personnel can walk around the component 360 degrees without blind spots, solving the problem that traditional suspended platforms or scaffolding cannot perform continuous circumferential operations, and greatly improving the quality and convenience of welding and anti-corrosion construction.

[0050] The platform windproof enclosure unit 44 is installed on the platform unit 41. It includes several vertical columns along the outer edge of the platform unit 41 and the platform opening and closing unit 42, as well as windbreak plates fixed between the columns, forming circumferential protection.

[0051] Retractable windproof bracing can be added to the outside of the windward side of the enclosure to further enhance wind resistance.

[0052] The platform buoyancy unit 45 is composed of multiple pontoons, which are fixed to the bottom of the platform unit 41 and the platform opening and closing unit 42, forming a matrix distribution to provide buoyancy so that the working platform module and its supporting overall structure can float on the water surface.

[0053] The floating self-climbing construction platform constructed using the above scheme is illustrated below with an example to show its working process in a specific application. It should be noted that this example does not limit the scope of this scheme. The specific steps are as follows: a. See Figure 5 The platform opening and closing unit 42 is fully opened by the drive component, and the first clamping unit 21 and the second clamping unit 22 are removed, so that the clamping module, the climbing module and the work platform module form fully open openings on the corresponding sides: b. See also Figure 6 After the overall structure is transported by sea to the designated location, the component to be climbed is allowed to enter the clamping module and the climbing module through the installation opening, and positioned in the center of the square clamping and climbing structure formed by the clamping module and the climbing module: c. See also Figure 7 Close and lock the platform opening and closing unit 42, reinstall the first clamping unit 21 and the second clamping unit 22 back to their original positions and fix them, so that the overall structure returns to the closed state.

[0054] d. See Figures 8-9 The motor drives the first clamping unit 21 and the third clamping unit 23 at the top to retract towards the component to be climbed, so that the two clamp the component to be climbed from opposite sides, thus completing the upper clamping. At this time, the second clamping unit 22 and the fourth clamping unit 24 are in the relaxed state.

[0055] e. See also Figures 10-11 The jacks of the first climbing unit 31 and the second climbing unit 32 are driven by motors. With the upper first clamping unit 21 and the third clamping unit 23 clamped and fixed to the component 5 to be climbed, the first climbing unit 31 and the second climbing unit 32 retract and, with the upper first clamping unit 21 and the third clamping unit 23 as the reaction force support, drive the lower second clamping unit 22, the fourth clamping unit 24 and the work platform module to be lifted upward as a whole.

[0056] f. See also Figure 12 The second clamping unit 22 and the fourth clamping unit 24 located at the bottom are driven by a motor to retract towards the member 5 to be climbed, so that the two clamp the member 5 to be climbed from opposite sides, thus completing the lower clamping. Then the first clamping unit 21 and the third clamping unit 23 are released from clamping the member 5 to be climbed.

[0057] g, see also Figure 13 With the second clamping unit 22 and the fourth clamping unit 24 clamped and fixed to the component 5 to be climbed, and the upper first clamping unit 21 and the third clamping unit 23 released, the jacks in the first climbing unit 31 and the second climbing unit 32 are extended by the motor, and the lower second clamping unit 22 and the fourth clamping unit 24 are used as reaction force support to drive the upper first clamping unit 21, the third clamping unit 23 and the work platform module to be lifted upward.

[0058] h. Repeat steps d to g. By alternating clamping of the upper and lower clamping units and alternating extension and retraction of the climbing units, the overall structure can be continuously climbed along the component to be climbed in an inchworm-like manner.

[0059] Once the overall structure has climbed to the designated working height, the upper and lower clamping units can simultaneously clamp the component 5 to be climbed, thus stabilizing the overall structure in the working position. At this point, construction personnel can carry out circumferential construction operations using the 2 working platform components.

[0060] Since the platform unit 41 and the platform opening and closing unit 42 together form a "U"-shaped working platform around the component 5 to be climbed, continuous working space can be formed around the component 5 to be climbed, which makes it convenient for construction personnel to carry out multi-directional and unobstructed installation, inspection, maintenance or reinforcement work on its outer perimeter.

[0061] Meanwhile, the platform windproof enclosure unit 44 is set around the perimeter of the work platform, which can form a ring enclosure for the working area inside the platform, reduce the impact of the marine wind and wave environment on personnel operation and construction safety, and improve the stability and safety of the working environment inside the platform.

[0062] i. After construction is completed, in the reverse order of steps d to g, the upper first clamping unit 21, the third clamping unit 23 and the lower second clamping unit 22 and the fourth clamping unit 24 alternately clamp the component 5 to be climbed, and coordinate with the alternating extension and retraction of the first climbing unit 31 and the second climbing unit 32, so that the overall structure moves downward along the component 5 to be climbed, and completes the reverse inchworm-like descent.

[0063] j. After the overall structure descends to the water surface, the platform buoyancy unit 45 provides buoyancy, allowing the overall structure to float on the water surface; then the platform opening and closing unit 42 is opened, and the first clamping unit 21 and the second clamping unit 22 are removed, so that the overall structure forms a fully open exit opening on the corresponding side.

[0064] k. The component to be climbed 5 is released from the clamping module and the climbing module through the exit opening, and the entire structure is transported away from the construction site by marine transportation equipment to complete the dismantling and recycling.

[0065] In summary, the floating self-climbing construction platform constructed in this scheme has the following advantages over existing technologies: 1. Provides a stable working platform: The openable "U"-shaped working platform enables unobstructed operation around the components to be climbed, significantly improving weld quality and construction safety.

[0066] 2. Self-climbing function: It adopts the inchworm-like alternating action of the upper and lower clamping units and the climbing unit, and can climb to any specified height autonomously without the need for external hoisting equipment.

[0067] 3. Adaptable to marine environment: The bottom buoyancy unit allows the platform to float on the water for transportation, positioning and recovery, while the windproof enclosure effectively reduces the impact of wind and waves.

[0068] 4. Reusable: The platform allows for easy removal of components and overall recycling, making it suitable for continuous construction of batch piles and columns, and offering good economic benefits.

[0069] 5. Improved construction efficiency and safety: Reduced reliance on scaffolding, large ship machinery, and temporary suspended platforms, achieving mechanization, automation, and standardization in offshore component construction.
