This utility model proposes a kind of ball valve actuator the most simultaneously, this actuator is by reseting spring device, power transmission, hydraulic means forms, described reseting spring device includes spring cylinder, spring, push pedal, described power transmission includes housing, piston rod, guide rod, guide block, bearing pin, shift fork, slide block, planetary gears, worm gear and worm screw, described planetary gears is made up of sun gear, planetary gear, ring gear, planet carrier, described worm gear and worm engaging, described ring gear is connected with worm gear, and described hydraulic means includes hydraulic cylinder and piston；Wherein, piston rod welds together with piston, push pedal, and piston rod is connected by bearing pin with guide block, slide block, and shift fork is connected with sun gear by spline, and the output shaft of planet carrier is connected with ball-valve valve rod, and worm gear, worm screw are arranged on housing.
In technique scheme, described worm screw is driven by underwater robot, and the power intake of worm screw is connected with the clutch end of underwater robot.
When using hydraulic-driven, ring gear is fixed, and no matter hydraulic pressure input source drives sun gear to rotate forward or reversely rotates, and power can be delivered on planetary gear by sun gear, is finally driven planet carrier to rotate by planetary gear, thus exports power.Now, not having power to input owing to ROV drives, worm screw maintains static, and has the worm-and-wheel gear of auto-lock function by ring gear locking, it is ensured that power is accurately transfer to planetary gear from sun gear.
When hydraulic-driven lost efficacy, sun gear does not has power input to be locked out under the effect of the back-moving spring of hydraulic drive mechanism, ROV drives provides power drive worm screw to rotate, the ring gear with worm gear one is driven to rotate, drive planetary gear and planet carrier to rotate by ring gear, thus realize the output of power.
This utility model simple in construction, is skillfully constructed；The transmission of planetary Bidirectional power and the reverse self-locking of worm and gear, make hydraulic-driven and ROV drive can separate non-interference action, enhance reliability and safety that deep-sea ball valve is opened, it is easy to produce, it is easy to assembling and changes, manufacturing cost can be substantially reduced.

Detailed description of the invention
Below in conjunction with the accompanying drawings with enforcement example, the utility model is described in further detail.
As it is shown in figure 1, embodiment one provides a kind of planetary gear mechanism, use the reverse self-locking function of planetary Bidirectional power transfer function and worm and gear, realize hydraulic-driven and the operating of the ROV non-interference driving ball valve of driving.This drive mechanism is made up of worm gear 5 and the worm screw 6 of planetary gears and band auto-lock function, and described planetary gears is made up of sun gear 1, planetary gear 2, ring gear 3, planet carrier 4, and described ring gear 3 is directly connected with worm gear 5.Wherein, sun gear 1 be connected with the hydraulic-driven axle of ball valve actuator and together with rotate, the output shaft of planet carrier 4 and ball-valve valve rod are connected and drive ball valve open and close.Worm gear 5 engages with worm screw 6, and worm screw 6 and worm gear 5 are interference fits, and during hydraulic failure, worm screw 6 is driven by underwater robot.
As in figure 2 it is shown, be the structure principle chart of fork type hydraulic-driven ball valve actuator.This actuator is by reseting spring device, power transmission, hydraulic means forms, left side reseting spring device includes spring cylinder 8, spring 9, push pedal 10, intermediate power transmitting device includes the planetary gear mechanism 20 realizing non-interference driving that housing 17, piston rod 12, guide rod 11, guide block 13, bearing pin 14, shift fork 16, slide block 15, this utility model provide, and right side hydraulic means includes hydraulic cylinder 18 and piston 19；Wherein, piston rod 12 welds together with piston 19, push pedal 10, and piston rod 12 is connected by bearing pin 14 with guide block 13, slide block 15, and shift fork 16 is connected with sun gear 1 by spline, the output shaft of planet carrier 4 is connected with ball-valve valve rod, and worm gear 5, worm screw 6 are arranged on housing 17.During hydraulic failure, worm screw 6 is driven by underwater robot.
When hydraulic oil promotes piston 19 to left movement, piston rod 12 other end push pedal 10 compression spring 9, guide block 13 along guide rod 11 to left movement, slide block 15 moves in the chute of shift fork 16, drive shift fork 16 and sun gear 1 to rotate simultaneously, transfer power to the output shaft of planet carrier 4 thus drive the valve rod of ball valve to rotate, it is achieved the opening and closing of ball valve.
