Description

Technical Field

[0001] The utility model relates to the field of offshore construction of new energy facilities, in particular to a multi-degree-of-freedom adjustable support frame for an offshore photovoltaic system. Background Technique

[0002] In recent years, with the increasing global demand for clean energy, the offshore photovoltaic system, as a new solar power generation method, has developed rapidly due to its vast sea area resources and less land restrictions. However, the construction and operation of offshore photovoltaic systems face many challenges, especially the installation link of offshore photovoltaic platforms. Due to the complexity and uncertainty of the offshore environment, such as the influence of waves, tides and winds, the offshore transportation and installation of large photovoltaic platforms have become the key points and difficulties in the construction process. Traditional installation methods, such as hoisting and fixed installation, are strictly restricted by water level changes and construction window periods, not only with low construction efficiency, but also with great potential safety hazards.

[0003] During the installation process of an offshore photovoltaic platform, the contact between the platform and the support structure is the key to ensuring the installation quality and safety. Traditional support structures often adopt fixed contact points. When facing large photovoltaic platforms, due to the large volume of the platform, combined with factors such as temperature stress and manufacturing errors, there will be large errors in the contact with the support structure, and even effective contact cannot be achieved, seriously affecting the fixing and jacking operations of the photovoltaic platform. Therefore, the existing technology has obvious deficiencies in dealing with the contact accuracy and adaptability between the photovoltaic platform and the support structure.

[0021] To ensure a firm contact between the support frame and the photovoltaic platform, the present utility model has carefully optimized the design of the contact plate and the contact adjustment assembly. By introducing a spherical contact plate and a hydraulically - driven support hydraulic rod and other structures, this solution realizes the adaptive adjustment of the contact surface, and can effectively address the problem of poor contact caused by platform shaking or installation errors. This design not only improves the adaptability of the support frame, but also reduces the difficulty and cost of installation and maintenance.
