Floating square matrix and floating type photovoltaic system

Abstract

The invention relates to the technical field of photovoltaic power generation, in particular to a floating square matrix and a floating type photovoltaic system. The floating matrix comprises connecting rod pieces and a plurality of main floating bodies, the main floating bodies are arranged at intervals in the length direction and the width direction of the main floating bodies, and the rows of main floating bodies arranged in the width direction of the main floating bodies and the rows of main floating bodies arranged in the length direction of the main floating bodies are arranged in a staggered mode. The connecting rod piece is used for supporting and fixing the photovoltaic module, the connecting rod piece can connect the main floating bodies arranged at intervals in the length direction of the main floating bodies and the main floating bodies arranged at intervals in the width direction of the main floating bodies, the contact area of snow and the main floating bodies is reduced, the load of the accumulated snow on the floating matrix is effectively reduced, and the deformation of the connecting rod piece is reduced; and a multi-row photovoltaic module installation mode and photovoltaic modules of various specifications can be flexibly adapted according to project requirements. The floating photovoltaic system provided by the invention is more stable in structure by applying the floating square matrix.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation, in particular to a floating square array and a floating photovoltaic system. Background technique [0002] In recent years, with the rapid development of the photovoltaic industry, large-scale photovoltaic power plants have grown rapidly, especially floating photovoltaic systems. Reliability and environmental protection have been widely recognized and become an important development direction of the photovoltaic industry in the future. [0003] At present, the floating square array supporting the photovoltaic power station is mainly divided into two types in terms of structure, one is a pure floating body type square matrix structure, and the other is a square matrix structure connected by floating bodies and connecting rods. The pure floating body type square array structure is that each floating body is connected through the lugs on the floating body. The floating body is...

AI Technical Summary

Problems solved by technology

The pure floating body type square array structure is that each floating body is connected through the lugs on the floating body. The floating body is divided into walkway floating body for operation and maintenance, main floating body for installing and fixing photovoltaic modules, and other auxiliary floating bodies. Except for the main floating body, other floating bodies are exposed to the outside, easy to form snow on the walkway floating body, resulting in insufficient buoyancy of the entire phalanx structure

In addition, if the pure floating body square array structure adopts the multi-row module installation method, the square array will have insufficient rigidity, which will cause photovoltaic modules to be greatly affected by water surface fluctuations and affect power generation efficiency.

The square structure of the connection between the floating body and the connecting rods is mainly to connect the floating bodies in series through the connecting rods. The lug connection between the floating bodies is only used as an auxiliary connection method. The photovoltaic modules are installed on the connecting rods. However, the end-to-end connection It is easy to form snow accumulation on the floating body, and when multi-row modules are installed, the connecting rods are also prone to deformation
