The contest included laying and connecting two trays of hoses, motorized pump trains, and water guns.

“Stay in position, prepare, start……”With the referee’s whistle, the players rushed out of the starting point like an arrow from the string, teammates on the side of the field shouted anxiously, and the players sweated and raced against time. There was a kind of "hot" atmosphere in the whole arena. The competition includes three projects: the water discharge exercise of the motorized pump train, the extension exercise of the hose at the water gun, and the connection of the two trays of the hose. There are sixty-year-old "veterans" and "newborn calves" on the competition field. Recruits”, everyone compares physical fitness, stamina, style, and courage. You chase after me, not to be outdone. The part-time firefighters have a tenacious fighting style and a brave fighting spirit.

It is understood that the participating township and township part-time firefighting teams are composed of 7 members. According to the standard of "one vehicle, one team, one room", they are equipped with fire trucks, fire fighting equipment, and built a special fire fighting garage. , Each team can receive 60,000 yuan of special government funding each year, which fundamentally solves the "worries for the future".

Xinhua County has a wide area and a large population. The 27 towns and towns under its jurisdiction are mostly remote villages.

Fire safety knowledge (1)

Fire is a natural phenomenon. Tamed fire is a friend of mankind. It brings light and warmth to people and promotes the progress of human civilization and society. However, if the fire is out of control and causes a fire, it will cause huge losses to people's lives and property. According to statistics, there were more than 140,000 fires in my country in 1997, with more than 7,000 casualties, and 8% of the fires were caused by children playing with fire. It can be seen how important it is for students to understand and master some fire protection knowledge to reduce and prevent the occurrence of fires.

The history of the assault boat

The prototype of the assault boat
According to the records of Motorboating in the Guinness Book of the World, the history of inflatable boats can be traced back to 880 BC. King Ashurnasirpal II, the Assyrian, ordered his troops to continuously inflate the greased hides so that they could pass the river. ! In ancient China, in the Song and Ming dynasties, people also used sealed and inflated animal skins to pass rivers. The emergence of the assault boat is mainly due to its speed

In 1839, after the Duke of Wellington made the first pontoon test of an inflatable boat, in 1840, the British Thomas Hancock designed an inflatable raft and included his work related introduction in the "British Natural "The Origin and Process of Rubber" in the book. In 1844, a navy captain Halkett designed a wheel-shaped inflatable boat, which was used in Arctic expeditions many times. Frenchman Clement Ader also designed a floating vessel. In fact, many other pioneers invented inflatable rafts, which heralded the birth of "inflatable boats". In 1913, Albert Meyer of Germany came up with a fairly novel design. By 1920, his company, Ginseng Bau Pneum. Boote is marketing his "Qi" ship, 9 of which have been used in the German army, and have gradually become an assault boat

Modern assault boat
In France and the United Kingdom, ZODIAC and RFD successively launched the first modern rubber boats. In 1919, the founder of RFD Ray Foster Dagnall tested an inflatable boat on Lake Wisely in the United Kingdom and improved his design in the 1930s. This is the ancestor of a popular inflatable life raft. In France in 1934, Pierre Debroutelle designed the prototype of an inflatable boat.

The first modern inflatable boat was used in the French Navy. The development model of ZODIAC triggered the rapid development of civilian and military inflatable boat industries. Correspondingly, Pierre Debroutelle designed the first U-shaped rubber boat in 1937. On August 10, 1943, he applied for a patent for this design. This is also the most straightforward version of sports and entertainment inflatable boats to this day.

Assault boat components and structure
Since then many new manufacturers, new models and new designs have been introduced to the market. Inflatable boats are no longer small inflatable boats on the back of a big yacht! It can reach 45 feet long or even longer! The “rigid” glass fiber reinforced plastic hull and aluminum hull have gradually replaced the original inflatable bottom! Luxurious and beautiful decorative parts, even the ship’s warehouse also appeared on the inflatable boat. Corresponding to its name, today, inflatable boats often just refer to the boat’s pontoons being inflated, and the bottom of the boat may be made of fiberglass and aluminum. However, inflatable boats have always existed and changed. More and more popular!
