Annular floating pipe type water-surface photovoltaic power generation system and mounting method

Abstract

The invention discloses an annular floating pipe type water-surface photovoltaic power generation system and a mounting method. The system comprises a platform unit, wherein the platform unit comprises an annular floating pipe group, a bottom bracket, a photovoltaic element support component, a photovoltaic plate and a connecting piece; the annular floating pipe group consists of a plurality of annular floating pipes which are different in curve diameter and are concentrically arranged; the bottom bracket is arranged at the upper side of the annular floating pipe group; the bottom bracket and the annular floating pipe group are fixed through the connecting piece; the bottom bracket consists of main brackets and auxiliary brackets; the main brackets and the auxiliary brackets are orthogonally arranged at the upper side of the annular floating pipe group, and the auxiliary brackets are parallelly arranged between the main brackets; the main brackets and the auxiliary brackets are fixedly connected with the photovoltaic element support component; the photovoltaic plate and the photovoltaic element support component are in embedded snap joint with each other. The photovoltaic power generation system adopts high modularization thinking; the floating pipes are connected into a plurality of concentric annular shapes different in radius, so as to serve as a module main floating body. In such a design, the connecting piece is reduced; the photovoltaic power generation system can be lifted to get into water after being installed on the land, so that the mounting difficulty is greatly reduced, and the overall stability and local stability are increased.

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
