Solar seawater desalination and heat preservation plafond of life raft

Abstract

The invention discloses a solar sea water desalination and heat preservation plafond of a life raft. The solar sea water desalination and heat preservation plafond is surrounded by an outermost anti-reflecting film layer and an innermost thermal-protective layer, a heat conduction layer is arranged on the thermal-protective layer, a heat absorption layer and a capillary layer are arranged on the heat conduction layer, and the lower end of the capillary layer and the lower end of the anti-reflecting film layer are respectively in a skirt side shape. The plafond is supported by six flexible ribs and an umbrella handle, the skirt sides of the capillary layer and the anti-reflecting film layer are placed in a water storage cabin which is separated form external sea water through a water seepage layer; and an evaporation cavity is formed among the heat absorption layer, the capillary layer and the anti-reflecting film layer, the upper end of the evaporation cavity is provided with a condensation layer which is arranged on the top of the plafond and is of a funnel shape, and a water collecting structure is formed below the condensation layer. When the solar sea water desalination and heat preservation plafond is used in a tropical sea area, the life raft enters water after being inflated, sea water is filled in the evaporation cavity from the capillary layer, an euphotic layer can accelerate a greenhouse effect in an upper cavity, absorbed solar radiation is converted into inner energy of sea water to be evaporated, and water vapor is condensed on the condensation layer so as to generate fresh water.

Description

technical field [0001] The invention relates to a life raft, in particular to a solar-powered seawater desalination heat preservation ceiling for a life raft, which can improve the survival probability of people in distress at sea. The multi-layer structure can achieve heat preservation in the cold zone, cooling in the tropics and providing the roof of the life raft with fresh water. Background technique [0002] The routes of international sailing ships often have to pass through various climatic zones, such as the Indian Ocean usually has a hot climate, while the North Atlantic Ocean has low water and strong winds and waves. In addition, shipwrecks often occur under extreme weather conditions, and the survival rate of seafarers in distress will be greatly reduced under high or low temperature conditions. Therefore, the shipwreck lifesaving device must ensure the temperature conditions of the people in distress as much as possible to improve their survival rate. However, ...

Problems solved by technology

[0004] After searching the existing technical documents, it was found that Chinese Patent No. CN200710302009.8 provides a solar multifunctional fully automatic unfolding non-overturning life raft. Although it provides related ideas for seawater desalination, its main content still relies on The originally equipped resources are used for passive lifesaving, and no specific desalination method is given

At the same time, its power and lift-off system has little application value in the reality of ocean rescue, and this rigid structure may damage the inflatable life raft

China, Patent No. CN200910165804.6 provides a luminous life raft. Although it provides the function of luminous light at night, in order to increase the chance of rescue, its structure and function are single, and it cannot cope with the reality of complex ocean conditions and long rescue time
