Annular floating tube water surface photovoltaic power generation system and installation method

Abstract

The invention discloses an annular floating tube type water surface photovoltaic power generation system and an installation method. The system includes a platform unit, and the platform unit includes an annular floating tube group, a bottom support, a photovoltaic element support assembly, a photovoltaic panel and a connecting piece; the annular floating tube group consists of several The ring-shaped floating tubes with different diameters are concentrically arranged, and the bottom bracket is arranged above the ring-shaped floating tube group. The bottom bracket and the ring-shaped floating tube group are fixed by connecting pieces. The sub-supports are arranged in parallel between the main supports, the main supports and the sub-supports are fixedly connected to the photovoltaic element support assembly, and the photovoltaic panel and the photovoltaic element support assembly are embedded and engaged. The photovoltaic system adopts a highly modular idea. By connecting the floating tubes into several concentric ring shapes with different radii, as the main floating body of the module, this design reduces the number of connectors and can be hoisted into the water after installation on land, greatly reducing the It reduces the difficulty of installation and increases the overall and local stability.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation, in particular to an annular floating tube type water surface photovoltaic power generation system and an installation method. Background technique [0002] At present, the photovoltaic power generation market is developing rapidly, but land resources have become an important limiting factor for the vigorous development of ground photovoltaic power plants at this stage. Floating photovoltaic power plants on water use some kind of floating platform to float photovoltaic modules on the water surface for power generation, which can greatly save land resources. At the same time, different from ground and roof photovoltaics, water surface photovoltaics have been vigorously developed in recent years because they are close to the water surface, have high power generation efficiency, can improve the climate and water ecological environment, and are easy to clean. At present, water s...

Problems solved by technology

The floating body type can be roughly divided into two types according to the arrangement method: one is to arrange one or several photovoltaic panels on a floating body to form a small unit, such as Chinese Patent No. CN105186968. The feature of this arrangement is that it is easy to install, but the unit The connection with the unit is usually a weak point, and the overall stability is poor, and the floating body structure is made of HDPE material, which has the characteristics of corrosion resistance and strong bearing capacity. However, due to the large amount of HDPE material used, the floating body requires high precision and high floating body cost. The other is to lay steel brackets on the floating body to form a square floating body platform, and then lay photovoltaic panels on the steel brackets to form a larger square matrix, such as Chinese Patent No. CN201320070930.5. This arrangement has slightly better stability. But there are many connections and installation is very troublesome

The floating tube arrangement is generally to build a steel bracket on the long floating tube, and then lay photovoltaic panels on the steel bracket, such as Chinese Patent No. CN104953934. This arrangement has the characteristics of easy acquisition of floating tubes, simple processing and manufacturing, and modularization of units. , but the connection between the unit and the unit is troublesome, and the stability of the straight pipe is far less than that of the circular pipe in the case of strong wind and waves
