Description

Technical Field

[0001] The utility model belongs to the technical field of offshore photovoltaic construction equipment, and specifically relates to a bottom-seat offshore photovoltaic conduit frame structure. Background Art

[0002] As the country's new energy power generation projects enter a stage of rapid development, various types of power generation projects are increasing, and land resources are becoming increasingly scarce. Among them, offshore new energy power generation projects will become the main battlefield in the future.

[0003] At present, prestressed concrete pipe piles or steel pipe piles are mostly used as the foundations in offshore photovoltaic projects. The photovoltaic brackets are basically hoisted as a whole. During the installation of fixed photovoltaic brackets, high requirements are placed on the position and verticality accuracy of the pile foundation. Any deviation will affect the overall hoisting of the bracket and components, and affect the component layout and power generation efficiency.

[0004] However, in actual engineering applications, in complex offshore environments, pile foundation construction currently uses the positioning system on the pile-driving ship to roughly locate the piles and then directly carry out pile foundation construction operations such as pile pressing. The pile position coordinates, pile body verticality and elevation are not strictly controlled. When there are large deviations in each group of several piles or the deviation exceeds the design allowable deviation, the overall lifting of the bracket and components will not be possible, which seriously affects the construction efficiency. The current pile foundation positioning method is prone to some pile foundations failing to meet the specifications, design and on-site construction requirements, resulting in large errors, leading to rework of prefabricated pile foundations, and repeated driving and pulling will disturb or even damage the foundation, resulting in low installation efficiency and difficulty in ensuring the quality of engineering construction, affecting the overall construction and installation qualification rate of the project.

[0005] The patent document with the publication number of CN201198927Y discloses a "separately installed conduit rack structure", which splits the eight-legged integrated conduit rack and welds it into two independent separate four-legged structures, and sets a positioning docking device on each of the two adjacent legs of the two four-legged conduit racks. Although the device is more convenient to install through the split design, the diameter of the conduit rack in the device cannot be adaptively adjusted, so the flexibility and applicability during use are insufficient and need to be improved.
