Description

Technical Field

[0001] The invention relates to a floating photovoltaic power station, belonging to the technical field of floating photovoltaic power generation. Background Art

[0002] Photovoltaic power station refers to a photovoltaic power generation system that uses solar energy and special materials such as crystalline silicon panels, inverters and other electronic components to connect to the power grid and transmit electricity to the grid. Photovoltaic power station is one of the green power development energy projects that the country encourages the most.

[0003] In order to save land resources, floating photovoltaic power stations used on water are gradually being widely used. In floating photovoltaic power stations, a bearing system needs to be set up to support photovoltaic modules. Specifically, the bearing system mainly includes a float and a bracket. The float only provides buoyancy, and the bracket is set on the float to support the photovoltaic modules.

[0004] For example, the Chinese utility model patent "Floating Photovoltaic Power Station and Its Supporting System" with the authorization announcement number CN209700889U, the supporting system of the floating photovoltaic power station includes a walkway float that provides buoyancy and forms a first operation and maintenance channel, the walkway float is provided with a fixing portion for being fixedly connected to the front side of the photovoltaic module, and one photovoltaic module is only fixedly connected to one walkway float located in front of it. In the supporting system of the above-mentioned floating photovoltaic power station, the walkway float has both the functions of supporting the photovoltaic module and providing buoyancy. Compared with the prior art float that only provides buoyancy, it reduces the number of components, thereby effectively reducing the cost; at the same time, when wave fluctuations cause adjacent walkway floats to have a displacement difference, since one photovoltaic module is only fixedly connected to one walkway float located in front of it, the impact of the displacement difference on a single photovoltaic module is effectively reduced, thereby reducing the probability of damage to the photovoltaic module and increasing the service life of the photovoltaic module. However, in this patent, one end of the component is connected to the float and the other end is connected to the purlin. Due to the different materials and mechanical properties of the float and the purlin, the deformation between the two is not synchronized, which will cause uneven deformation of the component and damage the component. At the same time, only one purlin is set under the component, and the component is connected to the purlin through a V-shaped support frame. The load on the V-shaped support frame is greater than the vertical load transmitted by the component, and as the V-shaped angle increases, the load amplification becomes more obvious. Therefore, in order to ensure the optimal installation spacing of the components, a high-strength V-shaped support with a large V angle is required, which will cause material waste.

[0005] For another example, the Chinese invention patent "A floating platform for installing photovoltaic modules on water" with patent publication number CN107054577A includes a float and a bracket arranged on the float, and photovoltaic modules are installed on the bracket, characterized in that: the float and the bracket form a number of floating units connected to each other, and the float of each floating unit includes more than three floats arranged in a straight line, which are small floats located at the north and south ends of the floating unit and a large float located between the two small floats, and the buoyancy of the large float is two to three times that of the small float. The main beam of the platform is fixed to each float by a first connecting member, and a front support and a rear support for installing photovoltaic modules are arranged in pairs on the main beam. The height difference between the front support and the rear support is adjusted to control the inclination angle of the module installation, and the photovoltaic module is connected to the front support and the rear support in a flexible hinged manner through the second connecting member thereon; etc. The present invention realizes processing and installation standardization and reduces costs. However, in this patent, different floating units are required to realize the module installation function, electrical equipment installation function, and operation and maintenance walkway function, and the number of component components is large and complex.
