10. a kind of wind powered street lamp according to claim 7, it is characterised in that: the blower rear portion of the blower fan system is equipped with
Empennage is so that blade face comes wind direction；When the wind powered street lamp can be carried out storage and release to the sun, include the following steps；
When A1, solar panel power generation, solar panel electric power distribution to wind powered street lamp is carried by control module
Battery charging, after control module predicts battery completely electricity, control module is electronic by standby solar panel electric power
Machine drives hydraulic backup pump to continue energy storage to accumulator；
A2, after the oil storage of accumulator is full, control module stops solar panel to standby motor；
When ambient is turned secretly to threshold value, control module with the electricity of battery to street lamp power supply, road lamp power supply, after the electricity of battery is finished, control
Molding block open throttle valve, accumulator start to hydraulic pump input high pressure oil come driven generator power generation, with to street lamp power supply, road lamp power supply into
Row illumination, the control module continue extra generator electric energy to charge to battery simultaneously；
A3, when three energy storage operations can be carried out when having the sun also has the daytime of wind, the energy storage operation includes control module pipe
It manages solar panel and rotates emergency generator to battery by hydraulic motor to battery charging, control module opening throttle valve
Charging, wind drive blade make hydraulic pump to accumulator energy storage；
When battery is full of, control module starts the hydraulic backup pump of standby motor drive, exports to the first high-pressure oil pipe high
Pressure oil, when accumulator stores full high pressure oil, control module closes standby motor, motor/generator stop operating it is hydraulic after
Standby pump stops to the first high-pressure oil pipe conveying high-pressure oil, while control module opens a point high pressure oil extra to valve or overflow valve
Branch to fuel tank.
