Abstract

The invention discloses a discrete walkway floating body and bracket combined water surface photovoltaic power generation device and method, which is composed of several photovoltaic module units (A), and is characterized in that: the photovoltaic module units (A) are equidistant along the horizontal and vertical directions Arranged, a cable bridge (7) is arranged in the middle of two adjacent photovoltaic module units (A) arranged in the longitudinal direction, and the cable bridge (7) is located on the main beam (6) of the support. Two crossbars (9) are longitudinally arranged below the same side of each photovoltaic module unit (A), and the inner crossbars (9) are connected to the main support below through the low connectors (10). The beam (6) is fixed, and the cross bar (9) described on the outside is fixed with the bracket (6) below through the high connector (8); it overcomes the shortcomings of complex structure, uneven load bearing and poor industrial versatility in the prior art , which has the advantages of solving the installation and disassembly of photovoltaic modules with small inclination angle and low center of gravity by setting reasonable fixing methods for different module types.

Technical field [0001] The present invention relates to the technical field of photovoltaic power generation, more specifically, a discrete walkway floating body and a support combined water surface photovoltaic power generation device and method. Background technique [0002] Compared with traditional ground-based photovoltaic power stations, floating photovoltaic power stations install photovoltaic power generation components on floating bodies on the water surface, which have the effect of not occupying land resources, reducing water evaporation, and inhibiting algae growth. At the same time, the water body can also cool photovoltaic modules and cables. Effectively improve power generation efficiency. [0003] my country is rich in water resources, with numerous lakes and reservoirs, and the market prospects for the development of floating photovoltaic power plants on the water surface are broad.

Problems solved by technology

[0004] At present, there are many design and construction schemes for various surface floating photovoltaic power plants, mainly based on the design of floating body plus components and the design of floating body, support and components. In the test stage, it generally has technical and economic characteristics such as complex structure, uneven load bearing, poor industrial versatility, complex construction technology, high cost, short project life, and difficult maintenance in the later stage, so it cannot be widely used.

If the design scheme of floating body plus components is adopted, all buoyancy and structural forces are provided and carried by the floating body, which requires high requirements for the floating body. The main problem is high cost, non-optimal inclination angle power generation, and the floating body is easy to deform, aging, and stress cracking , the surface hardness is low, easy to scratch, it is difficult to install and disassemble photovoltaic modules, and the project life is short, etc.; the combined design of walkway floating body, main floating body and steel bracket or the combination of full floating body walkway and steel bracket is adopted, that is, the buoyancy is provided by the floating body. The structural forces are all supported by steel support components. The main problems are uneven load bearing, excessive use of floating bodies and steel structures, complex connections and easy corrosion at the joints, poor water vapor corrosion resistance of steel supports, and difficulty in replacing floating bodies and photovoltaic modules.
