Research on Solar Power Generation Disaster Relief Tent Based on Inflatable Structure

Abstract

The local structure of disaster relief tent was analyzed by ANSYS. The deformation of inflatable column was basically consistent with the deformation of inflatable column after expansion, and the stress at different positions was also consistent with the basic size. The optimum ratio of height to width of arch was obtained to ensure the strength and stability of arch. At the same time, the optimal ratio of long axis to short axis of ellipse with small stress and strain was obtained. The suitable size was chosen to design the overall structure of the inflatable tent. The practical number and distribution mode of solar energy film was formulated, and the solar energy film was combined with tent. Finally, the inflatable structure tent with power generation function for disaster areas was obtained. Introduction In earthquake disasters, clothes and other materials were needed by the victims, and tents that could shelter the wind and rain were more needed in harsh environments [1].On May 12, 2008, a strong earthquake of magnitude 8.0 struck Wenchuan, China, requiring more than 3 million tents were erected in a few days. "Water Cube" stadium was the largest membrane structure project in the world at present, which means that domestic research on the materials and fabrication technology of inflatable membranes has gradually matured [2]. Inflatable membrane structure had been widely used in tent field [3]. Disaster relief tents were mainly used for temporary and short-term emergency relief. Most of the fabrics used were PVC or PU coated fabrics with poor air permeability or impermeability, which had poor warmth retention, thermal insulation and air permeability. Comfort was also a difficult problem in the design of tents in disaster areas. The existing disaster relief tents were heavy and inconvenient to transport. At the same time, the construction of disaster relief tents needs cooperation of many people to complete. Wind resistance of tents was mainly studied in the literature of new integral folding frame tent structures [4]; the feasibility of emergency tents and extension services from a spatial perspective were mainly studied in the literature of the design of emergency tents in post-disaster public space [5]; The design and research of inflatable tent [6] could reduce the difficulty of tent construction, and had the characteristics of lightness and convenient transportation. In the early stage of disaster relief, lighting was a big problem. . An inflatable tent with solar power could solve the problems of simple lighting difficulties and fast construction. Structural Design The inflatable structure of the tent was shown in Figure 1. Elliptical structure was adopted at the bottom and arch structure was used at the top as the tent skeleton [7]. The tent was composed of four parts: inside tent, outside tent and tent skeleton. The tent was equipped with solar power film,
