This is a popular science post about the development of miniature fire trucks

It has been hundreds of years since the advent of fire trucks to the present. Do you know what a fire truck is in the world? Next, the mini fire truck expert Shanghai Xizhiquan will give you a popular science.

1. 1518: The world's fire truck appeared in 1518. It was made by the craftsman Antony Bratner who was commissioned by the city of Augsburg, Germany to make metal crafts. This fire truck is a large water pump directly installed The water pump formed on the car is operated by a human lever, and the power of the car is derived from horse traction. Therefore, this car should be called a "fire fighting carriage".

2. 1666: In this year, a fire broke out in London, England. The fire burned for 4 days and 4 nights, and destroyed 1,300 houses including St. Paul ’s Church. Some medieval buildings were hit by this fire. After sweeping away, people gradually began to pay attention to the city's firefighting work. Soon after, the British invented the world's hand-pump fire truck and installed a water dragon to extinguish the fire. Of course, this fire extinguishing device is still installed on the carriage.

3. 1829: A fire engine equipped with a steam engine appeared this year, also in London, England. The inventor was the steam engineer John Breswaite. Although the fire engine was still towed by horses, it had said goodbye to manpower. The water pump, in which the fire pump is driven by a 10-cylinder twin-cylinder steam engine, is powered by coal and has a soft hose.

4. 1835: This year, New York City, the United States established the world ’s professional fire brigade. At that time, there were only four people in the establishment, specializing in firefighting work. In the next year, in 1836, this fire brigade also began with four people. Expanded to 40 people and later sequenced by NYPD.

5. 1901: Location Liverpool, United Kingdom. The Royal Carridi Company produced the world's first fire engine driven by an internal combustion engine, and was dispatched to perform tasks in August of the same year. At that time, this fire engine was still very imperfect, not only speed It is extremely slow and keeps tempering while driving.

6. 1920: In the 1920s, fire trucks working entirely on internal combustion engines began to appear. At this time, the fire trucks had a simple structure, and most of them were modified on existing truck chassis. Pumps and additional water tanks were installed on the vehicles. On the outside are fire ladders, fire axes, explosion-proof lights, and fire hoses.

After the article, the editor will give you a little knowledge about fire trucks. Do you know why fire trucks are red? Generally speaking, fire trucks in most countries are red. According to relevant investigations, every 100,000 red fire trucks are dispatched, causing 32 accidents. If the fire truck is painted in a more vivid yellow color, the number of accidents is only 14.5 for every 100,000 vehicles dispatched, which is more than half the decline, so they advocate that the fire truck be dyed yellow, but the fire department is firmly opposed to this because the yellow Stabilizing people's emotions will reduce the efficiency of firefighting, and the red color can more inspire the fighting spirit and inspire people.
