Lifeboat for emergency rescue

Abstract

The invention relates to a lifeboat for emergency rescue. The lifeboat comprises an elastic hull. The front and two sides of the elastic hull are provided with a first buoy assembly, on which a second buoy assembly is arranged. The back of the elastic hull is provided with an elastic coaming plate which is respectively connected to the first and second buoy assemblies. The lifeboat also comprises a power unit which is arranged on the elastic hull or the elastic coaming plate and is used for providing power. The invention has the following superior effects: during navigation, a lifeboat is easy to pierce by sharp apparatuses such as obstacles or foreign materials in water such that a first cavity of the first buoy assembly or second buoy assembly leaks air; a proper amount of an expansion foaming agent is filled into the first cavity through expansion foaming agent filling equipment until the first cavity is filled with the expansion foaming agent, so as to continuously utilize the first cavity to raise bearing capacity of the lifeboat and increase emergency rescue probability; and a lifebuoy assembly has functions of saving space, preventing scarification, preventing collision and increasing buoyancy and has an emergency lifesaving function, and the lifeboat has a simple structure and is safe and reliable.

Description

technical field [0001] The invention relates to the technical field of water rescue equipment manufacturing, in particular to a lifeboat for emergency rescue. Background technique [0002] In recent years, the shipping industry has developed vigorously, and the number of ships and shipbuilding technology have greatly improved. Although the general trend of maritime accidents in the world has slowed down, the number of maritime accidents remains high. According to statistics from relevant departments, at least 78 ships were wrecked in 2012, and about 981 people died in maritime accidents. In June 2015, a passenger ship sailing from Nanjing, China to Chongqing sank in the waters of Jianli, Hubei, in the middle reaches of the Yangtze River, killing more than 400 people and leaving many people missing. [0003] The lifeboat has the advantages of shallow draft, portability, and high mobility. It is mainly used for emergency rescue in flood fighting and disaster relief, and can a...

Problems solved by technology

[0004] The hulls of existing lifeboats are mostly composed of glass fiber reinforced plastics, plywood and rubber sheets. Because most of the existing lifeboats are heavy, they need to be transported by special storage vehicles. However, in areas where roads are washed out or blocked, due to The road conditions are poor, and it is difficult to move the entire lifeboat to its destination in time even if multiple people carry it together

[0005] In addition, the inflatable self-rescue boat is an effective escape and life-saving equipment in the event of flood disasters. Since it can be deflated and folded when not in use, it basically does not need to occupy a large space and is low in cost. Many flood disaster-prone areas use inflatable self-rescue boats. The boat is used as a backup safety escape device at home. The conventional inflatable self-rescue boat is basically a closed air chamber made of a polymer material. The self-rescue boat has a simple structure, is easy to manufacture, and has low cost, but it is prone to the following problems during use: First, the ability to resist wind and waves is poor, and flood disasters are often accompanied by violent wind and rain. When the wind is strong, it is easy to overturn the self-rescue boat, which brings life danger to the survivors. Chinese patent application number ZL2013103415350 and Chinese patent application number ZL2013204803715 have applied for a self-rescue boat that can adjust the counterweight, prevent wind and rollover, and facilitate communication with the outside world. And the lifeboat composed of multiple air chambers solves the problem of personnel escape in flood control and rescue to a certain extent, but it still has some places to be improved, for example, the accommodation space for the escape personnel is easily occupied by the hull after the hull is inflated , the hull is made of polymer film material. Although it has a multi-air chamber structure, it is still easy to be pierced by sharp objects such as preset obstacles or sundries in the water, causing the entire inflatable boat to leak air and lose buoyancy, which is harmful to the life and property of escapees. There is a high probability of hazard

Although the structure of the lifeboat discloses a hull for inflating, and the accommodation space inside the hull is provided with a rigid wall formed by plugging boards, which reduces the buoyancy of the lifeboat and affects the navigation speed, and its structure More complex and less practical
