Description
Technical Field
The invention relates to the technical field of photovoltaics, in particular to a floating body multifunctional integrated water surface photovoltaic support system suitable for alpine regions.
Background
The solar energy has the advantages of abundant resources, wide distribution, renewability, no pollution and the like, is an ideal clean energy source for human beings, makes an important contribution to the construction of a low-carbon society, and has an important position in a long-term energy strategy. In recent years, the development of the photovoltaic power generation market is very rapid, but the restriction factor of land resources is more obvious, and the market becomes the bottleneck of vigorous construction of land photovoltaic power stations. And surface of water floats formula power station as a novel photovoltaic power station form, utilizes certain body bearing structure to float photovoltaic module on the surface of water and generates electricity, when saving land resource in a large number, still possesses the evaporation of reduction water yield, suppresses alga and breeds, improves generating efficiency, cools off advantage such as subassembly and cable effectively. China has abundant water resources, lakes and reservoirs are numerous, the construction of the floating type water surface photovoltaic is the optimized utilization of resources, the photovoltaic application can be widened, and great attention and vigorous development are paid in recent years.
At present, the common floating body supporting platform at home and abroad mainly comprises two types: full-floating body type and floating body and bracket type. The lower part of each full-floating body type assembly is provided with buoyancy by a main floating body, and the main floating body is connected with a walkway floating body for providing an operation and maintenance channel. The module supporting component can be made into a type integrated with the main floating body, such as an integrated module supporting type disclosed in patents of CN201520668888.6, CN201520668888.6, CN201520606080.5, CN201620388933.7 and the like; or the assemblies may be supported by separate brackets secured to the main float as disclosed in patents CN201630171653.6, CN201720377962.8 and CN 201720527013.3. Although these designs have been used more extensively in existing engineering, there is room for optimization. For example, the design needs to arrange a large number of walkway floating bodies, so that buoyancy redundancy exists, and a space for further optimization is provided in terms of materials and cost; in addition, although the main floating bodies in most of the full floating body designs are provided with holes so as to save materials and increase the exposed area of the water surface to reduce the temperature of the assembly and improve the power generation efficiency, residual shielding exists after all, and the heat can not be dissipated to the maximum extent.
The number of the floating bodies used in the floating body and support type is obviously less than that of the full floating body type, the heat dissipation effect is better, and the case of large-scale engineering application is provided, but the existing design needs further optimization. For example, in CN 206878752U and CN 206490638U patents, the floating body can only provide buoyancy, the function is single, the operation and maintenance walkway needs to be additionally arranged, and the cost is increased; or as in CN 206734572U and CN 206226353U patents, the floating body is made of glass fiber cloth wrapped foam material, and the floating body is not waterproof and not sealed because the floating body is only wrapped by non-welding, so that the foam is easy to enter water to pollute the water body after being soaked for a long time, and the environmental protection property is poor. In addition, the bottom beam in the current design mostly uses standard type section (such as channel steel or square steel section), and for the section bar which can be extruded, such as aluminum alloy or glass fiber reinforced plastic, the purpose of light weight and large rigidity can not be realized by using the standard type section bar. Furthermore, no force transmission design exists in the current design of the assembly columns.
