"Rescue hovercraft" to solve complex environmental emergency rescue

Rescue service agencies around the world generally believe that the hovercraft can quickly fly over water, ice, floods, and snow, and perform fast and safe search and rescue operations. It is the only high-speed, effective rescue operation in response to special conditions such as swamps or beaches. platform. Because the hovercraft is based on the principle of aerodynamics, the air pressure pad lifts the hull to achieve a low-resistance state similar to magnetic levitation, and the air flow generated by the air propeller is used as a propelling force, so the hovercraft can adapt to a variety of complicated environments and travel fast.

As floods continue to spread throughout the country, relief efforts cannot be delayed.

In recent years, various news reports on floods have been seen from time to time. According to statistics, in 2015 , 319 people died in floods in China and 81 were missing . In 2016 , there were 51 heavy rainfall processes across the country with an average rainfall of 730 mm , 684 people died and 207 people were missing . The flooding of towns and towns is serious, and in 192 cities such as Wuhan, Nanjing and Jiujiang, internal conflicts have occurred. Not only the normal operation of the city has been affected, but various problems have also been encountered in the implementation of the rescue.

In the flood-fighting period, serious water accumulation on the urban road surface caused floods, submerged fields and other places were flooded, and there were also various floating objects, such as floating wooden boards and rubbish. Fire rescue teams rely on assault boats for water rescue. Propellers are often entangled with water grass, garbage, and other debris. They are also easily damaged when they encounter reef hulls. When the water depth is about 30 centimeters or when the water condition is not clear, the assault boat cannot be used. Fire engines are also not suitable. It is difficult to quickly reach rescue points to carry out rescue work.

In addition to floods, many people in distress are trapped in muddy beaches, swamps, ice caves and other harsh environments that require emergency rescue cases every year. Firefighters must use planking, ladders, or supine methods to reach the point of the person in distress. Such rescue methods are not only time-consuming and labor-intensive, but people in distress are likely to die because they cannot be rescued in a timely manner. In addition, fire fighters are also very likely to be trapped in deep danger in the rescue process. Cases of firefighters who died because of the rescue were heard. Rescue workers must try to save their lives by putting their lives in danger. They should have appropriate equipment to carry out rescue operations in a safe and fast manner.

Firefighters sacrifice themselves to save another life?

l Firefighters had a death rate of 13.33% due to flooding from 2005 to 2013 , which was the third leading cause of death for firefighters.

l 2010 Nian 7 20, Dalian fire brigade at the end of the bonded area non-commissioned officers Zhang oil depot explosion incidents, was involved in the sea died a heroic death in the implementation of monitoring tasks.

l 2016 Nian 6 20, Hunan Longshan county Lhez, firefighters rushed to the assault because of Yang Yu in the rescue in the flood, upside down in the water sacrifice, only 28 years old.

l 2017 Nian 10 30, Yunnan Lincang three people late at night to catch fish, one person was swept away by rushing water missing, two people were trapped, at any time may be washed away by the flood. The local fire squadron commander Tian Zhengjun led the team to the scene. After more than three hours of rescue, two people were trapped and rescued, but Tian Zhengjun was involved in the turbulent river and water sacrifice. He was only 27 years old.

The above list is only a few examples in recent years. These shocking figures and real cases have caused us to think deeply. Although rescue should not be delayed, how can firefighters' life safety be guaranteed? To avoid the casualties of rescue workers at work, it is necessary not only to increase the level of individual rescue technicians for firefighters, but also to provide scientific and sophisticated emergency rescue equipment.

Hovercraft's advantage in rescue and rescue

The hovercraft's "amphibious function" and "suspension characteristics" enable it to enter dangerous areas such as rapids, swamps, and mudflats, where vehicles and boats cannot reach. Hovercrafts are often the best platform to provide rescue services in these areas. It can better protect the rescue workers and quickly transport them to the rescue point for rescue. It is the most advanced equipment for water rescue in the world.
