Description

Technical Field

[0001] The present invention relates to the technical field of floating photovoltaic array operation and maintenance, and specifically to a floating photovoltaic array operation and maintenance method. Background Art

[0002] A four-row floating photovoltaic array is a power generation system that installs solar photovoltaic modules on the water surface. This power generation system generally uses the water surface as a supporting platform, and four rows and two columns of photovoltaic panels are installed on a special floating structure, thereby forming a photovoltaic power station floating on the water surface. The floating photovoltaic array can be built on a variety of water bodies such as lakes, reservoirs, ponds, and artificial reservoirs. In the prior art, operation and maintenance personnel are generally required to regularly maintain the floating photovoltaic array, and dismantle and replace photovoltaic panels that cannot be used normally or the main floating body where the photovoltaic panels are installed.

[0003] However, the traditional way of operating and maintaining floating photovoltaic arrays has the following problems: 1. The photovoltaic panels in the existing floating photovoltaic arrays are generally fixedly connected to the four corners of the main floating body through four connecting parts. When dismantling and replacing a single photovoltaic panel, the operation and maintenance personnel usually need to first set up an operation and maintenance ladder that spans the photovoltaic panels front and back on the corresponding main floating body and can be used for lying operation, and then remove the two connecting parts on the photovoltaic panel close to the walkway side, and finally lie on the operation and maintenance ladder to remove the two connecting parts on the photovoltaic panel away from the walkway side, thereby realizing the dismantling and replacement of a single photovoltaic panel. This method of dismantling and replacing photovoltaic panels is relatively cumbersome as a whole, resulting in a heavy overall burden on manual operation, and during the process of dismantling and replacing photovoltaic panels, the overall load borne by the main floating body is large, resulting in high overall loss and short service life of the main floating body; 2. In the prior art, when the photovoltaic panels are dismantled, the main floating body is subjected to a large load, which leads to high overall loss and short service life of the main floating body. When the photovoltaic panel is installed on the main floating body at a certain inclination angle, it is usually required for at least two operation and maintenance personnel to first adjust the inclination angle of the paired connectors corresponding to the front and rear sides of the photovoltaic panel, and then lock and fix the connectors with the adjusted inclination angles with bolts, and finally install the photovoltaic panel on the corresponding four connectors. This operation method of installing photovoltaic panels not only has many steps and high labor costs, but also the accuracy and consistency of the overall inclination angle adjustment of the photovoltaic panel still need to be further improved; 3. In the prior art, each front and rear adjacent main floating bodies, as well as the main floating body and the corresponding adapter are generally connected by bolts and nuts. When the main floating body is to be disassembled and replaced, it is necessary to manually remove and install the bolts and nuts at each connection in turn. This operation method makes the disassembly and installation of the main floating body more time-consuming and labor-intensive, thereby resulting in low efficiency in the overall operation and maintenance of the floating photovoltaic array.

This connection method can realize the rapid installation and disassembly of the main floating body 2 under the premise of ensuring the stable installation between the front and rear adjacent main floating bodies 2 and between the main floating body 2 and the corresponding adapter 11, thereby greatly reducing the time and burden of the overall installation and replacement of the main floating body 2, and thus greatly improving the efficiency of the overall operation and maintenance of the floating photovoltaic array.
