The utility model relates to a boat device, in particular to an improvement of a hydraulic device in a boat fin stabilizer device, and provides a boat high-reliability numerical control fin stabilizer device. The boat high-reliability numerical control fin stabilizer device comprises a fin shaft, a fin stabilizer fixedly mounted on the fin shaft and a hydraulic device driving the fin shaft to rotate, wherein a hydraulic oil input port of the hydraulic device is communicated with a valve output port of a digital valve, and a valve input port of the digital valve is communicated with a pump output port of an oil pump. By means of the boat high-reliability numerical control fin stabilizer device, the rotating angle of the fin shaft can be precisely positioned, control links are few, and the failure rate is low.
Description
Technical field
The utility model relates to marine equipment, relates in particular to the improvement of hydraulic efficiency gear in the ship stabilization fin apparatus.
Background technology
When boats and ships run into stormy waves in the navigation process, can produce the phenomenon of lateral oscillation, the lateral oscillation of boats and ships can reduce the navigability of boats and ships, the injured vessel body structure, influence equipment, the normal operation of instrument, also can cause goods displacement or bump to damage, passenger and crewman are swooned, may influence its fighting capacity to combat vessel, in order to reduce the lateral oscillation of boats and ships, many colleagues have carried out deep research, present effect terms of settlement preferably is at the turn of the bilge of boats and ships stabilizer and control setup thereof to be installed, control setup is made of acquisition of signal and disposal system, by measuring the angle of boats and ships lateral oscillation, remove to control the fin axle of stabilizer around the angle of its axis rotation in conjunction with control signal of factors such as speed of the ship in meters per second output, control setup contains closed loop control system, need to measure the angle that the fin axle rotates, and feed back to control setup, with the accurate control that realizes that the fin axle rotates, in this control setup that is constituted by closed loop control system, controlling unit and parts thereof are more and complicated, have the high hidden danger of fault rate.Can accurately control fin axle rotational angle at present, and lower stabilizer peculiar to vessel and the control setup thereof of fault rate there is not solution preferably as yet.
The utility model content:
At the prior art above shortcomings, the purpose of this utility model is that a kind of high reliability numerical control fin stabilizer peculiar to vessel will be provided, and it can accurately locate fin axle rotational angle, and controlling unit is few, and fault rate is low.
In order to solve the problems of the technologies described above, the scheme that the utility model solves its technical matters is: high reliability numerical control fin stabilizer peculiar to vessel, comprise the fin axle, be fixedly mounted on the stabilizer on this fin axle and drive the hydraulic efficiency gear that described fin axle rotates, the hydraulic oil input port of this hydraulic efficiency gear is connected with the valve output port of digital valve, and the valve input port of described digital valve is connected with the pump output terminal mouth of oil pump.
After adopting such scheme, because the hydraulic oil input port of hydraulic efficiency gear is connected with the valve output port of digital valve, the valve input port of described digital valve is connected with the pump output terminal mouth of oil pump, the volume that enters the hydraulic oil in the hydraulic efficiency gear cylinder body can be realized accurately control by digital valve, and the mode of operation of digital valve can be by computer controlled, thereby can adopt computing machine to pass through accurate control to the hydraulic efficiency gear forced stroke and realize accurate control to the stabilizer deflection angle, and it is simple in structure, volume is little, be convenient to install, again owing to do not need to install detection and the positioner of fin axle rotational angle, simplify the structure of control setup, thereby improved the reliability of control setup.
The valve output port of described digital valve refers to the hydraulic oil output port of digital valve.
The valve input port of described digital valve refers to the hydraulic oil input port of digital valve.
The pump output terminal mouth of described oil pump refers to the hydraulic oil output port of oil pump.
Described digital valve drives also opening and shutting off of control figure valve core by the output shaft rotation of stepping motor.
Described digital valve is by stepping motor opening and shutting off by the reciprocating type driving of ball-screw and control figure valve core.
Described digital valve drives also opening and shutting off of control figure valve core by electromagnet apparatus.
Description of drawings:
Below in conjunction with the drawings and specific embodiments the utility model high reliability numerical control peculiar to vessel fin stabilizer is further described.
Fig. 1 is the structural principle scheme drawing of the utility model high reliability numerical control peculiar to vessel fin stabilizer.
The specific embodiment:
Among Fig. 1, high reliability numerical control fin stabilizer peculiar to vessel, comprise fin axle 8, be fixedly mounted on the stabilizer 9 on this fin axle 8 and drive the hydraulic efficiency gear 7 that described fin axle 8 rotates, the hydraulic oil input port 6 of this hydraulic efficiency gear 7 is connected with the valve output port of digital valve 45, and the valve input port 3 of described digital valve 4 is connected with the pump output terminal mouth of oil pump 12.Because the hydraulic oil input port 6 of hydraulic efficiency gear 7 is connected with the valve output port 5 of digital valve 4, the valve input port 3 of described digital valve 4 is connected with the pump output terminal mouth of oil pump 12, the volume that enters the hydraulic oil in hydraulic efficiency gear 7 cylinder bodies can be realized accurately control by digital valve 4, and the mode of operation of digital valve 4 can be by computer controlled, thereby can adopt computing machine to pass through accurate control to hydraulic efficiency gear 7 forced strokies and realize accurate control to stabilizer 9 deflection angles, and it is simple in structure, volume is little, be convenient to install, again owing to do not need to install detection and the positioner of fin axle rotational angle, simplify the structure of control setup, thereby improved the reliability of control setup.
