The installation of supports and photovoltaic panels is a critical step in offshore photovoltaic construction, requiring significant investment in both construction and labor costs.

[0003] Currently, offshore photovoltaic module construction involves first installing and securing the brackets on a pile foundation, followed by the installation of the photovoltaic panels using a temporary offshore platform. Specifically, a piling vessel performs pile foundation construction. Once the piles are complete, the brackets are installed, and finally, a temporary offshore platform is set up. The temporary platform primarily consists of a springboard, which workers secure at both ends to the bracket purlins. The photovoltaic panels are then installed on the temporary platform using mechanical assistance. In practical application, this process requires a large temporary platform, requiring significant manpower and material resources, resulting in low installation efficiency.

The supporting device 6 can provide sufficient supporting force to carry the weight of the photovoltaic module and also has the function of adjusting the height, which is convenient for adjustment under different water levels and installation requirements. It is used to lift the photovoltaic module so as to move the photovoltaic module. The setting of the supporting pulley 7 is used to cooperate with the sliding track 3 to realize The photovoltaic assembly now slides along the sliding track 3. Preferably, the supporting device 6 is a jack, which is used to be installed at the bottom of the photovoltaic assembly, and the supporting pulley 7 is installed at the supporting end of the jack. The jack is installed on the photovoltaic assembly by bolts, which is convenient for disassembly and assembly; the sliding track 3 is used to provide a track for the sliding of the photovoltaic assembly, which is convenient for quickly moving the photovoltaic assembly to the installation position, and helps to improve efficiency; the traction device 4 is used to provide power for the sliding of the photovoltaic assembly, without manual pulling, which helps to reduce work intensity and ensure safety. The traction device 4 is a winch, which is installed at one end of the sliding track 3, and the traction end of the winch is used to be connected to the photovoltaic assembly;

[0024] A temporary work platform 2 for assembling offshore photovoltaic modules 5 is installed on the offshore truss 1 on one side of the sliding track 3. The temporary work platform 2 is used to provide a stable working space for the assembly, commissioning and preliminary installation of photovoltaic modules. The platform must be equipped with necessary tools and protective facilities to ensure the safety and efficiency of the workers.

[0025] In order to better cooperate with the installation of photovoltaic modules, the structure also includes a temporary support for assisting the installation of offshore photovoltaic modules 5. The temporary support includes a bottom support 9 and a tilting support 8. One end of the tilting support 8 is hinged to the bottom support 9, and the other end of the tilting support 8 is connected to the bottom support 9 through an adjustable support member 10. A temporary pulley 11 for sliding cooperation with the sliding track 3 is also installed at the bottom of the bottom support 9.

[0026] The present invention provides an offshore photovoltaic module installation structure that can be used for offshore photovoltaic installation construction, solving the problems of the existing installation process such as the large temporary operation platform 2, the difficulty of construction operation, low efficiency, and high risk, and can further improve installation efficiency and safety.

[0027] When in use, first lay the sliding track 3 on the upper part of the truss, then set up a temporary working platform 2 at one end, assemble the photovoltaic bracket and photovoltaic panel components into a whole on the platform, and then move the whole component to the sliding track 3. A winch is set at each end, and the winch pulls and controls the photovoltaic component to slide as a whole to the installation position and fix it. Specifically:

[0028] Taking the installation of photovoltaic modules on the first axis as an example, a temporary operating platform 2 is set up near the coast based on the installed truss foundation, and sliding tracks 3 made of channel steel are laid from near to far. Then, photovoltaic support units are assembled on the temporary operating platform 2. The photovoltaic support units are divided into long units and short units, and the sliding systems of the two units can be used alternately.

[0029] When installing a short unit, a jack is installed on the crossbar at the bottom of the photovoltaic module bracket, and a supporting pulley 7 is installed at the bottom of the jack. At this time, the jack is in a jacking state, so that the legs of the photovoltaic module bracket are suspended in the air, and then the photovoltaic panel assembly is laid on the upper part of the bracket. After the overall assembly is completed, the unit is pulled by a winch and slid along the track to the preset installation position;

[0030] When installing long units, temporary brackets need to be installed at the cantilevered positions on both sides of the PV module bracket. The height can be adjusted by controlling the retraction and extension of the basket bolts to achieve reliable support for the PV module bracket.

[0031] After the photovoltaic module is moved into place and fine-tuned, the jack is retracted, the photovoltaic module is unloaded onto the truss as a whole, and then the photovoltaic module bracket is bolted to the truss;

[0032] After each unit is slid, the jack, sliding track 3 and temporary bracket of this section are removed, and then the next unit is slid and installed. The sliding of the short unit and the long unit are alternately cycled until the installation of the axis is completed.

[0033] The advantages of the present invention are:

[0034] 1. Reduced manpower input and improved installation efficiency;

[0035] 2. High degree of mechanization and good overall installation effect;

[0036] 3. Effectively reduce safety risks and alleviate the pressure of safety supervision and management;

[0037] Compared with the existing offshore photovoltaic installation process, the present invention has the advantages of high efficiency and safety, strong operability, and saving labor and machinery costs. It has important practical significance for improving the efficiency of offshore photovoltaic installation construction and ensuring the safety of construction team workers.
