Description

Technical Field

[0001] The utility model relates to the technical field of offshore construction of new energy facilities, and in particular to a dynamically adjustable offshore photovoltaic platform installation system. Background Art

[0002] As the global demand for renewable energy continues to grow, offshore photovoltaic facilities, as an important part of clean energy, are expanding in scale. However, the installation of offshore photovoltaic platforms faces unique challenges. Traditional installation methods, such as hoisting, are often limited by the complexity and unpredictability of the marine environment, especially in shallow waters with large water level changes. Hoisting operations are easily affected by tides, wind and waves, and currents, resulting in a narrow construction window, low efficiency, and high safety risks. Therefore, it is particularly urgent to develop a new installation technology that can adapt to the complex offshore environment and improve installation efficiency and safety.

[0003] Offshore photovoltaic platforms are usually large truss structures that require precise positioning and stable installation on the water. In shallow waters, the water depth varies greatly, which requires the installation equipment to not only adapt to changes in water levels, but also to operate efficiently in a limited space. In addition, the dynamic characteristics of the offshore environment, such as wind, waves and currents, place higher demands on the stability and safety of the installation process. Therefore, the ideal installation technology should have excellent shock absorption performance and three-dimensional precision control capabilities to ensure the accurate installation of the photovoltaic platform while minimizing the impact of external environmental factors.

[0004] Currently, most of the installation technologies for offshore photovoltaic platforms in the market rely on hoisting or single jacking methods, which are insufficient in the face of complex marine environments. Hoisting technology is subject to water level and weather conditions, while traditional jacking technology often cannot achieve precise control of long strokes under large water level changes and is easily disturbed by external dynamic factors. In addition, existing installation technologies also have defects in the connection and alignment between the photovoltaic platform and the mounting bracket, which may lead to instability and safety risks during the installation process.

The shock-absorbing control seat 43 cooperates with the top support base 2 and moves on the first guide rail 41 through the linear drive member 44. Meanwhile, the movement in the Y-axis direction is controlled through the second guide rail 42 to achieve positioning within the plane.

The guide groove 836 on the control frame cooperates with the guide balls to ensure smoothness during the movement of the top support base 2. Meanwhile, through the sliding cooperation between the guide balls and the sliding guide plate on the top support base 2, stable movement of the top support base 2 is achieved. In addition, the rotation adjustment unit 9 realizes rotational adjustment of the top support base 2 in the Z-axis direction through the rotating table 91, the rotating groove, the rotating circular frame 92 and the rotating unit. The guide gear set and the drive motor 333 control the rotation of the rotating gear, thereby achieving all-round positioning of the top support base 2.

[0095] Generally speaking, the shock-absorbing control mechanism 3 absorbs and reduces external impact forces through the shock-absorbing pull rope 32, the shock-absorbing spring 454 and the shock-absorbing connection unit 45, providing a relatively stable working environment for the three-dimensional control mechanism 4. Based on the shock-absorbing control mechanism 3, the three-dimensional control mechanism 4 realizes all-round precise positioning of the top support base 2 through precise X and Y-axis movement and Z-axis rotational adjustment, ensuring precise alignment and installation of the photovoltaic platform. The two cooperate with each other. The shock-absorbing control mechanism 3 provides a stable foundation, and the three-dimensional control mechanism 4 realizes precise control, jointly ensuring safe, stable and precise installation of the photovoltaic platform in a complex marine environment. Among them, the combination of dynamic balance and precise control, the shock-absorbing control mechanism 3 responds to external impact forces through real-time feedback, while the three-dimensional control mechanism 4 realizes three-dimensional positioning of the top support base 2 through precise adjustment. In addition, the cooperative control strategy realizes comprehensive control of the installation process of the photovoltaic platform through real-time adjustment of the shock-absorbing control mechanism 3 and precise control of the three-dimensional control mechanism 4, ensuring installation quality and efficiency.

[0096] When using this adjustable jacking installation bracket system, first use the three-dimensional control mechanism 4 to move the top support base 2 to a predetermined position, and then use the jacking mechanism 5 to jack up the jacking support assembly 6 to the first position for preliminary positioning. Subsequently, adjust the height of the jacking support assembly 6 as needed and perform secondary positioning through the limit insertion rod 536. Repeat the above steps until the expected height is reached. During this process, the shock-absorbing control mechanism 3 always works to absorb vibration energy, ensuring smooth installation of the photovoltaic platform. Finally, reliable connection between the photovoltaic platform and the support frame is achieved through the abutting plate mechanism 8.
