The ballast water of one of them transmission power buoyancy aid (being set as A buoyancy aid) adjustment adjustment ballast tank 20 is squeezed in utilization, A floatation is increased, and sink, make the water level in the transmission power buoyancy aid pond 1 (being set as A pond) at A buoyancy aid place increase, adjustment cabin is pressed onto setting height;
Utilize another transmission power buoyancy aid pond (being set as B pond) to the water filling of A pond, make A water level in water pool rise to setting height, B water level in water pool drops to setting height;
Drop is maximum in the pond (A pond, B pond) of two buoyancy aids, and the variable height of two buoyancy aids (A buoyancy aid, B buoyancy aid) is less, can use low lift, large discharge water pump, improves the utilization ratio of water pump;
A buoyancy aid is positioned at highest order to two buoyancy aids (A buoyancy aid, B buoyancy aid), B buoyancy aid is positioned at lowest order.
2, open the 5th and open and close valve 15, first keying valve 11, open and close valve 16, second keying valve 12 control A pond by the 6th to circulate to B pond, open the 6th and open and close valve 16, second keying valve 12, A pond through hydraulic turbine generator 14 to B tank drain, A pond is high-order, B pond low level, flow from high to lower, when setting buffers has hydraulic turbine generator 14 or Reversible Pump-Turbine, current drive hydraulic turbine generator 14 or Reversible Pump-Turbine generating.
3, when A pond, B water level in water pool are parallel, close the 6th and open and close valve 16, second and open and close the neutral position that valve 12, two buoyancy aid (A buoyancy aid, B buoyancy aid) is positioned at pond.
4, A buoyancy aid squeezes into the ballast water in adjustment cabin to B buoyancy aid, and A buoyancy aid rises, and A water level in water pool declines, and B buoyancy aid sinks, and B water level in water pool rises, and now, A pond is positioned at lowest order, B pond is positioned at highest order.
5, the 6th keying valve 16, second keying valve 12 is often opened under normal circumstances, open and close valve 15, first by the 5th and open and close valve 11 control B pond to A tank drain, open the 5th and open and close valve 15, first keying valve 11, B pond through hydraulic turbine generator to A tank drain, hydraulic turbine generator is generated electricity, when draining into water level and being identical, A buoyancy aid, B buoyancy aid are positioned at the neutral position in pond.
6, by circulation, A buoyancy aid, B buoyancy aid pond pump, and rotated realize generating by the first lever 6 drivening rod 9; Meanwhile, two corresponding work done buoyancy aids 25 of setting pump along with pond 23, utilize the second lever 26, and force transfer to connecting rod 28, drivening rod 28 rotates and realizes electrical power generators.
Above-described embodiment is only one of preferred embodiment of the present invention, not limits practical range of the present invention with this, therefore: all equivalence changes done according to shape of the present invention, structure, principle, all should be covered by within protection scope of the present invention.
