The invention relates to a jacking
potential energy ejecting artificial rainmaking method and
system based on a
smart power grid and relying on mountain potentials. The method and
system are characterized in that an upward
catapult upward
orbit and an parallel gravity downward
orbit, which are respectively matched with an upward
orbit car and a downward orbit car, and an fixed-wing electric powered unmanned aerial vehicle used for spreading rainfall agent pushed or pulled or bore by the upward orbit car are arranged relying on mountain potentials; a cable connected with the upward orbit car bypasses a crown block
assembly on the top end of the upward orbit and the downward orbit and is connected with the downward orbit car; a cable connected with the downward orbit car bypasses the crown block on the lower end of the downward orbit and the crown block on the lower end of the upward orbit, and is connected with the upward orbit car; the lower
tail segment of the downward orbit or the downward orbit car is provided with an impacting
kinetic energy buffer recycle device running to the
tail segment of the downward orbit; the upward orbit car is provided with a
carriage return
sump providing downward
momentum potential energy; an upper reservoir injecting water to the
carriage return
sump and a lower reservoir receiving water from the
carriage return
sump are arranged on a mountain and down the mountain respectively; the lower reservoir delivers the water to the upper reservoir relying on the off-peak
electricity of the
smart power grid, and power is generated when the water is drained from the upper reservoir to the lower reservoir to charge the electric powered unmanned aerial vehicle. The method and
system have the advantages that the cost is low, the applicability is extensive, the rainfall effect is good, and the problem of widespread water shortages in a short period is solved.
