Description
Technical Field
The invention relates to the technical field of photovoltaic power generation, in particular to a pavement integrated solid filling water-blocking type water surface photovoltaic power generation system.
Background
The photovoltaic power generation system utilizes the photovoltaic components, the inverter and other equipment to form the power generation system, and is an environment-friendly, safe and reliable green energy source. Photovoltaic power stations are green electric power development energy projects encouraged by the country and make an important contribution to the construction of a low-carbon society. However, due to low photovoltaic power generation energy density, the occupied area is large under the same capacity configuration, and precious land resources are occupied. The number of reservoirs, lakes and mining subsidence areas in China is large, and the water surface photovoltaic is built by utilizing the idle water surface space, so that the resources are optimally utilized, the land resources can be reasonably utilized, the generated energy is improved, the water body environment is protected, and the floating dust is reduced.
The environment where the water surface floating photovoltaic power station is located is moist, structural components are easy to corrode, and in order to ensure corrosion resistance and service life of floaters, hollow blow molding high-density polyethylene floating bodies are generally adopted to provide buoyancy for components of the water surface photovoltaic power station, small-sized equipment such as a string inverter, a combiner box and the like.
The structural form of the hollow blow molding product has great influence on production efficiency and quality, and the flat structure with uniform thickness is most favorable for blow molding into the floating body with uniform wall thickness. The photovoltaic power station needs to support the photovoltaic module by utilizing the floating objects to a certain angle, and the floating objects have special shape requirements. At present, most floating body structures at home and abroad only consider meeting the requirement of the inclination angle of power generation, but neglect adverse factors brought to production and quality control. How to optimally design the floating body structure so as to meet the use requirement and facilitate production is a problem which needs to be solved at present.
Since 2015, the development of water surface photovoltaic technology in China is rapid, and particularly in coal mining subsidence areas in two-Huai areas, the construction of a plurality of water surface photovoltaic power stations is finished at present. The area of the water area of the subsidence area is limited, the construction requirement of the water surface photovoltaic power station is difficult to meet, and a plurality of water surface photovoltaic power stations gradually develop to water surface areas such as reservoirs, lakes and the like. Different from the subsidence area, the water areas such as reservoirs, lakes and the like integrate a plurality of functions such as water supply, cultivation and the like, if the floating body form similar to the subsidence area is adopted, the water surface area can be blocked in a large area, the contact of air, sunlight and water is blocked, and the death of aquatic organisms caused by the lack of oxygen in the water body is caused. Therefore, the shielding of the floating body to the water surface is reduced on the premise of ensuring the quality, the function and the stability of the floating body, and the improvement of the light transmittance and the hydrophilicity of the floating body is a problem to be solved by the development of the water surface photovoltaic technology.
Compared with calm coal mining subsidence areas, water areas such as lakes, rivers and the like have more severe environments, wind, wave and current loads are larger, whether the connection between the floating bodies can adapt to severe water surface environments or whether the connection can release energy accumulated by the wave and current acting on the floating bodies is one of the problems to be solved urgently.
At present, a hollow floating body is adopted as a floating body of the photovoltaic module, once the floating body has a break to cause water seepage of the floating body, the floating body can lose buoyancy, so that the photovoltaic module or other equipment on the floating body sinks into water, and the safety of a photovoltaic power station is endangered. Hollow blow-molded high-density polyethylene floating bodies filled with environment-friendly solid materials which are insoluble in water and have a density smaller than that of water are widely used in the market, but the hollow blow-molded high-density polyethylene floating bodies are applied in a small amount, so that the problems of breakage and water leakage of the floating bodies can be solved, and the problems still exist.
