Step-by-step unfolding and folding photovoltaic support, mobile photovoltaic power generation device and construction method of mobile photovoltaic power generation device

Abstract

The invention discloses a step-by-step unfolding and folding photovoltaic support. The support includes a foundation bearing auxiliary beam, a cabin body and the two foldable photovoltaic modules that are fixed on the upper surface of the foundation bearing secondary beam, and the locking mechanism that is arranged on the cabin body. The two photovoltaic assemblies are rotatably arranged on the foundation bearing auxiliary beams and located on the two sides of the cabin body respectively. The locking mechanism comprises two locking pieces extending out of the two sides of the cabin body respectively. The photovoltaic module comprises a plurality of rotatably connected photovoltaic units and has a first state in which the photovoltaic units are unfolded to form a tiled splice plate shape and a second state in which the photovoltaic units are folded to form a plurality of laminated plate shapes, and in the second state, the photovoltaic module stands on the foundation bearing auxiliary beam; and the locking piece is used for locking the photovoltaic module when the photovoltaic module stands on the foundation bearing auxiliary beam. The invention further discloses a mobile photovoltaic power generation device and a construction method thereof. The photovoltaic power generation system can be quickly built in a specified scene, is convenient to transport and small in occupied area, can realize high-power power generation after being unfolded, and is flexible and practical.

Description

technical field [0001] The invention relates to the field of photovoltaic technology, in particular to a step-by-step unfolding and folding photovoltaic support, a mobile photovoltaic power generation device and a construction method thereof. Background technique [0002] With the development and progress of society, the sustainable development of the environment and resources has attracted more and more attention, and the utilization of new energy has become more and more important. The solar photovoltaic power generation process is simple, there are no mechanical rotating parts, no fuel consumption, no emission of any substances including greenhouse gases, no noise, no pollution, and the solar energy resources are widely distributed and inexhaustible. Therefore, compared with new power generation technologies such as wind power, biomass power and nuclear power, photovoltaic power generation is a renewable energy power generation technology with the most ideal characteristi...

Problems solved by technology

[0004] However, due to the low energy density of solar energy, this makes the photovoltaic power generation system occupy a large area. The photovoltaic power generation system is usually built in an open and remote area, and the ultra-long-distance transmission of electric energy will cause energy loss and increase the cost of electricity.

As a result, the photovoltaic power generation system is restricted by the construction site, and it cannot be quickly built in the specified scene, which limits the application and popularization of the photovoltaic power generation system. In the case of high-power mobile power supply, the construction of existing photovoltaic power generation systems requires a long period of time, and cannot provide power supply in a timely manner.
