Description

Technical Field

[0001] This invention relates to the field of marine photovoltaic technology, specifically to an adjustable and safe operating platform for marine photovoltaic steel structure installation pile foundations. Background Technology

[0002] Offshore photovoltaic (PV) power, as an important development direction for clean energy, boasts numerous advantages, including zero land occupation, excellent sunlight conditions, and the ability to be developed in synergy with the offshore wind power industry. It is suitable for various marine conditions, including tidal flats and nearshore areas, and is now widely used in various new energy infrastructure projects. The pile foundation structure is the core load-bearing foundation of an offshore PV power station. After the pile foundation construction is completed, multiple high-altitude, water-based operations are required, such as pile top cutting, steel structure support welding, anti-corrosion treatment, and PV bracket assembly, all carried out using a work platform. The structural performance of the work platform directly affects the safety and progress of offshore PV construction.

[0003] Currently, offshore photovoltaic (PV) pile foundation construction mostly utilizes temporary scaffolding or simple working platforms. These conventional structures have poor adaptability, making it difficult to accommodate PV pile foundations of different specifications and sizes, thus limiting their versatility. Furthermore, complex marine conditions such as tides and waves continuously disturb these temporary structures. Conventional platforms lack overall structural stability and have weak resistance to wind and wave disturbances, making them prone to structural swaying and displacement during operations, posing certain safety hazards for working at heights. The erection and dismantling of temporary structures are cumbersome, resulting in a large on-site construction workload, making it difficult to meet the demands of rapid offshore construction. Moreover, their reusability is poor; after dismantling, they are difficult to adapt to different pile foundation conditions, easily leading to waste of construction materials and increased project costs. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a highly adaptable, adjustable, and safe operating platform for offshore photovoltaic steel structure installation using pile foundations.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] An adjustable safety operation platform for offshore photovoltaic steel structure installation pile foundation includes a pile foundation body and a platform body. Multiple sets of positioning clamps are fixed along the height of one side of the outer wall of the pile foundation body. The platform body is generally set as a U-shaped structure. Multiple sets of support frames are supported at the bottom of the platform body and inside the opening on the other side of the outer wall of the pile foundation body. Each set of support frames faces the pile foundation body and is fixed with a corresponding matching positioning clamp. A diameter adjustment pad is provided between the positioning clamp and the opposite connecting clamp. Bolts are passed through the positioning clamp, the diameter adjustment pad, and the connecting clamp to achieve mutual locking and fitting. A vertical ladder is fixed at the bottom of the platform body.

[0007] The present invention, which adopts the above technical solution, has the following prominent features compared with the prior art:

[0008] By arranging positioning clamps on the outside of the main pile foundation and cooperating with connecting clamps and diameter adjustment pads at the end of the platform, the clamping size can be adjusted according to the outer diameter of the pile foundation, making it suitable for various specifications of photovoltaic pile foundations. This improves the limited versatility of traditional work platforms. Furthermore, relying on multiple sets of support frames and the separate locking installation structure of the clamps, the platform can be quickly assembled and disassembled, simplifying on-site construction procedures and reducing on-site workload. The disassembled platform can be reused to adapt to different pile foundation conditions, reducing material waste and lowering construction costs. The multi-clamp layered locking structure improves the connection and fit between the platform and the pile foundation, mitigating structural swaying and displacement caused by sea waves and tidal disturbances, enhancing the overall stability of the platform, and ensuring the safety and progress of high-altitude, water-adjacent pile foundation operations.

[0009] As a preferred embodiment, a further technical solution of the present invention is:

[0010] Preferably, the platform body is equipped with a U-shaped hollow base frame, with a fall protection net laid inside the base frame. The outer edge of the U-shaped hollow base frame is fixed with a guardrail extending vertically upward, which can form a continuous protective structure on the outside of the platform. The hollow base frame structure can reduce the overall weight of the platform and reduce the impact of wind loads on the platform. Combined with the fall protection net, it can provide protection and shielding for workers and construction tools, making up for the shortcomings of the single protective structure of traditional simple platforms and improving the overall safety of high-altitude operations at sea.

[0011] Preferably, the exposed surfaces of the platform body are coated with a corrosion-resistant protective layer, which can form a protective barrier for the platform steel structure, reduce the corrosive effects of marine salt spray and humid seawater environment on the structure, delay the rusting and aging of the structure, maintain the structural strength and performance of the platform, extend the turnover service cycle of the platform, and adapt to long-term complex marine working conditions.

[0012] Preferably, the vertical ladder frame is integrally welded from square tubing. The top of the vertical ladder frame is rigidly fixed to the bottom surface of the U-shaped hollow base frame. The lower part of the vertical ladder frame is equipped with anti-sway clamps that encircle the outer wall of the main pile foundation. The integrally welded ladder frame structure has better overall integrity. Combined with the dual-point fixing method at the top and bottom, it can improve the stability of personnel moving up and down. The lower anti-sway clamps can limit the swaying and displacement of the bottom of the ladder frame, improve the problem of insufficient stability of the simple structure relied on by traditional offshore workers, and provide safe and reliable passage conditions for personnel to go up and down the platform.

[0013] Preferably, the outer walls of the topmost positioning clamp and the connecting clamp are provided with anti-fall lugs at intervals, providing standardized attachment points for the high-altitude anti-fall components. The attachment points are directly connected to the pile foundation bearing structure, ensuring reliable stress performance and meeting the anti-fall protection requirements for high-altitude operations at sea, further improving the platform's safety protection system.

[0014] Preferably, each set of support frames at the bottom of the platform body is equipped with symmetrically arranged support components. The support components are erected between the two sides of the connecting clamp and the bottom of the platform body. The support components include straight struts arranged parallel to the central axis of the pile foundation and inclined tie rods arranged in a cross pattern. The two ends of the straight struts and the inclined tie rods respectively connect to the bottom of the platform body and the outer wall of the connecting clamp. The support components can form a stable mechanical bearing system, improve the connection stiffness between the support frame, the clamp, and the platform body, distribute the platform's operating load and wind and wave impact load, reduce the local stress deformation of the platform, further improve the platform's overall anti-disturbance capability and structural stability, and adapt to the complex wind and wave operating environment at sea.

[0022] The present invention will be further illustrated below with reference to specific embodiments. The purpose of this illustration is solely to provide a better understanding of the invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0023] like Figures 1 to 6As shown in the figure, this embodiment provides an adjustable safety operation platform for offshore photovoltaic steel structure installation, including a pile foundation body 1 and a platform body 2. The platform body 2 is made of Q355B U-shaped high-strength steel. Multiple sets of positioning clamps 3 are fixed along the height of one side of the outer wall of the pile foundation body 1. These positioning clamps 3 are evenly arranged vertically along the pile foundation and are firmly bonded to the outer wall of the pile foundation by welding, thus pre-forming a standardized positioning and installation benchmark to avoid on-site installation misalignment. The platform body 2 is designed as a U-shaped structure. The U-shaped structure extends outwards by 75cm, allowing for rapid lateral clamping of the pile foundation without requiring overall hoisting from the pile top. This design is suitable for confined offshore hoisting operations. Multiple support frames are installed at the bottom of the platform body 2 and within the opening on the other side of the outer wall of the pile foundation body 1. Each support frame has its end facing the pile foundation body 1 and is fixed with a corresponding matching positioning clamp 3 and connecting clamp 4. Diameter adjustment pads 5 are provided between the positioning clamp 3 and the corresponding connecting clamp 4. The number of adjustment pads can be increased or decreased according to different pile outer diameter specifications, allowing for fine-tuning of the two sets of... The clamping spacing of the clamping plates adaptively matches different specifications of pile foundations, and can be adapted to various offshore photovoltaic pile foundations with diameters of Φ600mm-Φ800mm. It eliminates the assembly gap between the clamping plate and the pile body. Bolts are passed through the positioning clamping plate 3, diameter adjustment pad 5, and connecting clamping plate 4 to achieve mutual locking and fitting. The assembly method of symmetrical locking with multiple sets of bolts ensures that the clamping plate is uniformly stressed as a whole, avoiding the problem of displacement and loosening caused by unilateral stress, and achieving rigid fitting and fixing between the platform and the pile foundation. A vertical ladder frame 6 is fixed at the bottom of the platform body 2, and the clamping plate is made of 60x4 flat steel.

[0024] Preferably, the platform body 2 is equipped with a U-shaped hollow base frame 21. The base frame 21 is made of 25×25x2mm square tubing. A fall protection net 22 is laid inside the base frame 21. A guardrail 23 extending vertically upward is fixed to the outer edge of the U-shaped hollow base frame 21. The guardrail 23 is double-layered and 1.2m high, with a spacing of ≤600mm. The double-layered guardrail is made of 20×20x2mm square tubing, which can form a continuous protective structure on the outside of the platform. The hollow base frame 21 structure can reduce the overall weight of the platform and reduce the impact of wind loads on the platform. Combined with the fall protection net 22, it can provide protection and shielding for workers and construction tools, making up for the shortcomings of the single protective structure of traditional simple platforms and improving the overall safety of high-altitude operations at sea.

[0025] Preferably, the exposed surfaces of the platform body 2 are coated with a corrosion-resistant protective layer, which can form a protective barrier for the platform steel structure, reduce the corrosive effects of marine salt spray and humid seawater environment on the structure, delay the rusting and aging of the structure, maintain the strength and performance of the platform structure, extend the turnover service cycle of the platform, and adapt to long-term complex marine working conditions.

[0026] Preferably, the vertical ladder frame 6 is integrally welded from square tubing. The vertical ladder frame 6 is 4m long and made of 25×25x2mm square tubing. The top of the vertical ladder frame 6 is rigidly fixed to the bottom surface of the U-shaped hollow base frame 21. The lower part of the vertical ladder frame 6 is equipped with anti-sway clamps 7 that encircle the outer wall of the main pile foundation 1. The integrally welded ladder frame structure has better overall integrity. Combined with the upper and lower dual-point fixing method, it can improve the stability of personnel going up and down. The lower anti-sway clamps 7 can limit the swaying and displacement of the bottom of the ladder frame, improve the problem of insufficient stability of the simple structure relied on by traditional offshore workers, and provide safe and reliable passage conditions for personnel to go up and down the platform.

[0027] Preferably, the outer walls of the topmost positioning clamp 3 and connecting clamp 4 are provided with anti-fall lugs 8 at intervals, providing standardized attachment points for high-altitude anti-fall components. The attachment points are directly connected to the pile foundation bearing structure, ensuring reliable stress performance and meeting the anti-fall protection requirements for high-altitude operations at sea, further improving the platform's safety protection system.

[0028] Preferably, each set of support frames at the bottom of the platform body 2 is equipped with symmetrically arranged support components 9. The support components 9 are erected between the two sides of the connecting clamp plate 4 and the bottom of the platform body 2. The support components 9 include straight struts arranged parallel to the central axis of the pile foundation body 1 and inclined tie rods arranged in a cross pattern. The straight struts and tie rods are made of φ16 round steel. The two ends of the straight struts and tie rods respectively connect to the bottom of the platform body 2 and the outer wall of the connecting clamp plate 4. The straight struts bear the vertical working load, and the tie rods bear the lateral wind and wave impact load. They work together to form a stable mechanical support system, effectively dispersing and resolving concentrated stress, avoiding single-point deformation and breakage of the support frame. The support components 9 can form a stable mechanical bearing system, improve the connection stiffness between the support frame and the clamp plate and the platform body 2, disperse the platform working load and wind and wave impact load, reduce the local stress deformation of the platform, further improve the overall anti-disturbance capability and structural stability of the platform, and adapt to the complex wind and wave working environment at sea.
