Description

High-adaptation easy-expansion rigid-flexible combined type water surface photovoltaic floating system

Technical Field

The invention relates to the field of photovoltaic power generation, in particular to a high-adaptation easy-expansion rigid-flexible combined water surface photovoltaic floating system.

Background

Under the double-carbon background, the development of the photovoltaic industry enters the express way again, and the surface photovoltaic is the main battlefield of the photovoltaic industry. The photovoltaic body is used as the basis of the water surface photovoltaic power station, and is optimized and improved continuously along with the development of the industry in order to adapt to various environments, adapt to various components and adapt to the requirement of the photovoltaic power station on the continuous reduction of the cost of the floating body. Factors that currently have the greatest impact on the production and cost control of floats include:

as the capacity of individual components continues to increase, the dimensions of the individual components, including the lateral and longitudinal dimensions, continue to increase. According to the assembly installation requirements of each assembly manufacturer, in order to ensure the safety and stability of the assembly, the installation fixing point of the assembly is ensured to meet the requirements of the assembly manufacturer. The spacing between the mounting points of the components is therefore increasing as the size of the components increases. There are three main ways for manufacturers to solve this problem:

as shown in patent CN201920432945.9, the support spacing of the brackets is increased by using V-shaped brackets. However, this solution has two problems: firstly, the V-shaped support is mainly made of flat steel, the strength of the flat steel is difficult to provide effective support in the whole life cycle of the photovoltaic power station, and part of power stations find that the flat steel is deformed, so that the inclination angle of the assembly is reduced and the power generation capacity of the power station is reduced; secondly, along with the further increase of the size of the component, the distance between two supporting points of the V-shaped flat steel cannot be increased continuously. This method cannot completely solve the problem of the support interval becoming large due to the increased size of the module.

As shown in patent CN201920494305.0, in order to ensure that the distance between the supporting points meets the requirement of the assembly manufacturer, the width of the main floating body is increased. The mode has increased the production and processing degree of difficulty of main body, and along with the further increase of subassembly size, if main body size increases once more, will not have the machine can produce the main body of corresponding size. This approach also fails to address the above problems.

As shown in patent CN201920432945.9, the traditional full HDPE floating body form is abandoned in the form of a south-north steel bracket connecting walkway floating body, the steel bracket is used as a bearing component of the whole floating system and a rooting point of a component bracket, and the distance between supporting points is ensured to meet the requirements of component manufacturers by adjusting the positions of the adjacent steel brackets. The form completely returns to the original floating body plus steel bracket form, and the rigidity of the whole floating system is good, but the fatigue resistance performance is poor. The steel support is as main atress component, and is fixed through the mode of hard joint with the pavement body, under the alternating load of photovoltaic power plant long-term operation, because great intensity difference between steel support and the body, destruction appears in the tie point very easily, and steel support is as main atress component moreover, appears stress fatigue easily under the alternating load and leads to the component to warp and even break.

In addition, some manufacturers adopt the full HDPE floating body form, but the supporting point distance of the components does not comply with the requirements of the component manufacturers, so that the hidden crack of the components is caused during the long-term operation of the power station, and great risk is brought to the safety and the stability of the whole power station.

Because there is above-mentioned technical problem in the design and the production of current body for jumbo size photovoltaic module's application is difficult to popularize. These factors constitute difficulties that hinder the application of large-size components, and also hinder the popularization of water surface photovoltaic power stations, and even more hinder the realization of the dual-carbon target.
