Problems solved by technology

This patent is easy to install and the connection between the floating bodies is firm, but there are the following problems: the left and right sides of the main floating body supported by the photovoltaic module are respectively connected to different walkway floating bodies. Damage to photovoltaic modules; there are too many types of floating bodies, and the cost of mold opening is high, which may reduce production efficiency; there is no fixed support between the long metal brackets of photovoltaic modules, which will easily cause the deformation of the two brackets to be out of sync, resulting in damage to photovoltaic modules
None of the above-mentioned patents considered the versatility of the installation and fixation of electrical equipment such as string inverters and combiner boxes on the water surface, nor did they mention the laying scheme of cables on water

Abstract

Disclosed are a three-in-one coupling insertion-pull type water surface photovoltaic power generation unit and a power generation system thereof. The photovoltaic power generation unit comprises a passage floating body and a connecting floating body arranged on a side wall of the passage floating body, wherein a power generation element is arranged on the connecting floating body. The system is formed by assembling three-in-one coupling insertion-pull type water surface photovoltaic power generation units vertically and horizontally. Horizontally, the passage floating body is assembled with a passage floating body of another three-in-one coupling insertion-pull type water surface photovoltaic power generation unit, and so on, mounting is completed. Vertically, the connecting floating body is assembled with the passage floating body of another three-in-one coupling insertion-pull type water surface photovoltaic power generation unit, and so on, mounting is completed. Finally, connecting floating bodies of a horizontal row of three-in-one coupling insertion-pull type water surface photovoltaic power generation units are independently fixed with passage floating bodies, so as to complete mounting of the whole power generation system. The unit has the characteristics of simple structure, convenient mounting and multi-functionality. The system assembly has the characteristics of simple structure and convenient mounting.

Description

technical field [0001] The invention relates to the field of photovoltaic power generation, and specifically refers to a three-in-one coupled plug-in water surface photovoltaic power generation unit and a power generation system thereof with simple structure, convenient installation and low processing difficulty. Background technique [0002] Photovoltaic power generation system refers to a photovoltaic power generation system that uses solar energy and uses special materials such as crystalline silicon panels, inverters and other electronic components to connect to the grid and transmit power to the grid. Photovoltaic power plants are currently the most encouraged green power development energy projects by the state, and have made important contributions to building a low-carbon society. However, land photovoltaic power plants occupy a large area and cannot reasonably allocate land resources. However, my country has a large number of idle water surface resources such as res...
