How does the Archimedes screw water wheel work?

Built in a location with rapid water flow and uses the upstream water flow to drive the waterwheel.

A water wheel must be a drum truck used to lift water.

Principle:

The bamboo tube plays the role of a turbine: it supports the momentum of the water (provided by the kinetic energy (speed) of the water), and the energy obtained turns the tube wheel. And overcome the frictional resistance of the drum car and the reaction moment of the water lifted on the drum car).

When rotated at a certain angle, the bamboo tube initially immersed in water (filled with water) will leave the water and be lifted up. At that time, because the mouth of the bamboo tube is higher than the bottom of the tube (that's why the mouth of the bamboo tube faces the direction of the tube truck), there will be l water in the bamboo tube.

When the bamboo tube passes the top of the tube truck (when yoube bamboo begins to pour water), the position of the mouth of the tube begins to lower relative to the bottom of the tube, and the water in the bamboo tube will pour into the sink. You can adjust the position of the sink so that it can accommodate more water.

When you find that the drum truck rotates too slowly or cannot lift the water, you should install wooden boards or bamboo boards on the drum truck to enable the drum truck to obtain more energy (kinetic energy). some water. You can also immerse the cart deeper in the water to obtain energy (this way, because the angle between the position of the bamboo tube when it comes out of the water and the axis of the cart is more large, the height difference between the tube mouth and the bottom of the tube are also larger, which can make the memory of the bamboo tube pour more water).

When the speed of water flow is fsmall, the bamboo tube should also be relatively small. Otherwise, the energy that the tube car obtains from the water is limited and is not enough to overcome the reaction moment of the water. water raised on the tube vehicle (or in other words: potential energy).

In this way, the water is raised in a cycle.

The efficiency of the drum car itself is very low, but it does not need to be powered.

500-watt hydropower generation must meet at least two conditions: First, there must be a huge gap. In rivers with high specific fall rates, narrow valleys in rivers or the use of high artificial dams, large falls can occur, resulting in strong downward momentum and horizontal flow velocity.

Second, there must be huge traffic. A river with only a difference in height and without significant flow cannotform strong hydraulic power. Therefore, the flow rate plus the height difference is the main basis for determining whether hydraulic power is abundant. The water drop we use here actually uses the gravitational energy of the water.
