Abstract:
1. An energy storage power generating system comprising two series of motor units and their equipments for using the energy, one of the motor units is the main power source which constantly rotates when there is wind, which includes at least one to a multiple of wind-energy power machines which drive a generator in operation to generate electricity, or which transmits the power through a power output shaft, a clutch, a gear which connects a power output end gear of the respective wind-energy power machine to a first common transmission shaft provided with a constant speed controller, the power is then through a transmission member transmitted to a second common transmission shaft which is shared by the standby power source, and the common transmission member drives the generator to generate electricity, or the generator is driven to generate electricity through the integration of vertical series connection and parallel connection combined system; the other series of the motor unit is a standby power source, which includes at least one to a multiple of wind-energy power machines, at least one to a multiple of air compressor which generate high pressurized air, and sufficient containers which accumulate pressurized air and at least a turbine which uses the pressurized air to generate rotation power or a pneumatic motor or a fluid pump, and a high pressure air piping and a solenoid valve as well as sub-containers provided on each floor; the at least one to a multiple of wind-energy power machines drive the air compressor to do work, or through the power output shaft, a clutch, a bevel gear which connect the respective wind-energy power machine the power is transmitted to a common transmission shaft, a transmission member or a reduction gearbox drives the air compressor to do work, or through the integration of vertical series connection and parallel connection combined system the power is transmitted to drive the air compressor in operation, the generated pressurized air is accumulated in the container; the connection piping between the container of the air compressor and the next container is provided with a check valve, the solenoid valve and the throttle valve are provided in the piping between the container and the turbine or the pneumatic motor or the fluid pump; the turbine and the pneumatic motor are driven in operation by the pressurized air supplied by the container, and through a second common transmission shaft, clutch and a common transmission member the generator is driven to generate electricity; the motor units as the main power source and as the standby power source are selected by means of an automatic controller system which controls the time to alternately operate the motor unit, its controlling mode or program is as follows, when there is natural wind, the both wind-energy power machine units and air compressor set or the fluid pump operate simultaneously to do work, but the turbine or the pneumatic motor or the water-wheel machine is in the shutdown state, the clutch on the second common transmission shaft is disconnected, the motor unit as the main power source drives the generator in operation to generate electricity; when the natural wind blows so weakly that the speed of the motor unit as main power source or the power output or the generator power is lower than a predetermined value, the automatic controller system sends a command to let the clutch of the first common transmission shaft disconnect, at the same time the solenoid valve automatically opens, the throttle valve controls the flow rate of the pressurized air in the container, the pressurized air is inputted into the turbine or the pneumatic motor and the rotation power is generated, the clutch of the second common transmission is automatically closed, the output power drives the generator to generate electricity, or it controls and drives the water-wheel machine and power generating unit to generate electricity.
