Floating body multifunctional integrated water surface photovoltaic supporting system suitable for high and cold areas

Abstract

The invention relates to a floating body multifunctional integrated water surface photovoltaic supporting system suitable for high and cold areas. The system comprises a floating body support, a support and an assembly support, wherein the support is formed by vertical intersecting and fixed connecting of a plurality of cross beams and a plurality of longitudinal beams, and the floating body support comprises floating body units. The floating body support simultaneously integrates four functions: providing buoyancy, providing walkways, and serving as a transverse bottom beam and a protective longitudinal beam. The floating body support can provide buoyancy and can also provide a walkway function; the floating body units of the floating body support are connected with the longitudinal beams and play a role of transverse bottom beams, so that the connection function of an existing cross beams is enhanced, and the integrity of the array units is enhanced. Due to the fact that the inertia moment of the floating body is far greater than the inertia moment of the longitudinal beams, the floating body support is connected with the longitudinal beams, loads on the longitudinal beams can be transmitted to other longitudinal beams through the floating body units to be shared together, thereby achieving the averaging of the beam loads, protecting the bottom beam, improving structural safety, and reducing the cost.

Description

technical field [0001] The invention relates to the field of photovoltaic technology, in particular to a floating body multifunctional integrated water surface photovoltaic support system suitable for alpine regions. Background technique [0002] Solar energy has the advantages of abundant resources, wide distribution, renewable, and no pollution. It is an ideal clean energy for human beings, has made important contributions to building a low-carbon society, and plays an important role in long-term energy strategies. In recent years, the photovoltaic power generation market has developed rapidly, but the limiting factors of land resources have become more and more obvious, which has become a bottleneck for the vigorous construction of land photovoltaic power stations. As a new type of photovoltaic power station, the surface floating power station uses a floating body support structure to float photovoltaic modules on the water surface for power generation. While saving a lot...

Problems solved by technology

For example, in CN 206878752 U and CN 206490638 U patents, the floating body can only provide buoyancy and has a single function, and the operation and maintenance walkway needs to be arranged additionally, which increases the cost; or as in CN 206734572 U and CN 206226353 U patents, the floating body adopts the type of glass fiber cloth wrapped foam material , because it is not welded and only wrapped, the floating body is not waterproof and not sealed, and the foam is easy to enter the water and pollute the water after soaking for a long time, and the environmental protection is poor

In addition, the current design of the bottom beam mostly uses standard cross-sections (such as channel steel or square steel cross-sections). For extruded profiles, such as aluminum alloy or glass fiber reinforced plastics, the use of standard cross-sections cannot achieve the purpose of light weight and high rigidity

Furthermore, there is no force conduction design in the current design of the component column
