Ancient pumps—shovel pumps

A water pump is an ancient agricultural tool used by the Han people; it is a water-fetching mechanism that makes use of the principle of levers. A water pump consists of a crossbar and a long rod; one end of the crossbar is connected perpendicularly to the long rod by a straight rod, while the other end has a bucket filled with water suspended there by a rope. When people place the bucket on the crossbar of the pump, the other end of the crossbar sinks, while the top end of the long rod rises ； When the bucket is lifted, the other end of the crossbar rises, while the top end of the long rod drops. In this way, it is easy to draw water from lower places and transport it to higher places. The water pump played an important role in ancient Chinese agricultural production, especially in areas with scarce water resources. Until the 1950s, water wheels were still in use in some rural areas of southern China.
The water pump was an agricultural tool used by the Han people in ancient China for drawing water, operating primarily on the principle of levers. It consists of a crossbar and a long rod; one end of the crossbar is vertically connected to the long rod via a straight rod, while the other end is equipped with a bucket for holding water. When in use, human power is used to move the bucket up and down to lift water from a lower position to a higher one. The design of the water pump is simple yet efficient, making it particularly suitable for areas with limited water resources. Until the 1950s, some rural areas in southern China were still using water wheels, demonstrating their long-term importance in agricultural production. .
The water pump – well, the ancients were wise
