Today we will talk about a simple and effective method that will allow you to raise water from areas located in the lowlands. This method was used in ancient times. And today it does not lose its relevance. With its help, territories are drained, water is transported in places where there is no free access to electricity.
The creation of a unique mechanism dates back to about 250 BC. Its inventor is Archimedes, and therefore today the mechanism is called the Archimedes screw.
The mechanism, like all ingenious inventions, is quite simple. It is based on a hollow tube, and inside it is a screw. During the rotation of the screw (it is set in motion by hand or with the help of a wind or water wheel), the liquid rises in a spiral. The main thing is that the mechanism is at a certain angle to the horizon.
Our ancestors similarly raised water for irrigation, drained sewage pits and swamps. The advantage is that absolutely any liquid can be lifted using the mechanism.
Today, similar designs are often installed in hatcheries. Archimedes screws lift aquatic inhabitants without injuring them. These mechanisms are very popular in Holland, where it is necessary to regularly drain coastal areas that are below the water level.
Take a look at your kitchen grinder. Even it uses an Archimedes screw. With its help, the shredded products are transported to the knives.
Some craftsmen, trying to simplify the design, subject it to some changes. But the essence remains the essence. The mechanism is similar to a screw pump, only it has a different design.
The screw does not always rotate inside a stationary pipe, the body of the structure can also rotate. The screw is not a necessary element of the mechanism. It can be replaced by an ordinary tube attached to the shaft in the form of a spiral. The only constant condition is the angle of inclination of the entire structure to the horizon.
To raise liquid in large volumes, the flexible pipe can be replaced with a corrugation, the diameter of which reaches 110 millimeters.
Archimedes screw is the best option for irrigating areas located near water bodies. A water wheel will help to set the shaft of the mechanism in motion; it is enough to fix it downstream.
