Description
Technical Field

Background
Water delivery main canals, especially artificial water delivery main canals, generally adopt a self-flowing mode, such as a main canal of a central line project in north-south water diversion, and a water delivery channel as long as 1200km adopts a self-flowing mode in the whole process. A control gate 64 seat for controlling the function is arranged on the flow channel of the main canal. The main canal of the central line of north-south water diversion has a highest total head of only 100m and a runner length of 1200km, so that the flow velocity of water in the canal is slow, which is less than 0.9m/s on average, in a self-flowing mode, the too-slow flow velocity not only limits the water delivery quantity, but also easily causes the water quality to be polluted by surface source and atmospheric settlement, and causes the water quality to be poor. These phenomena of north-south diversion of mains ditches have become a common problem for mains ditches that are fed by gravity flow.
Therefore, there is a need to develop a hydrodynamic water delivery device.
