Abstract
The invention relates to a marine device, in particular to improvement of a hydraulic device in a marine fin stabilizer device. The marine high-reliability numerical control fin stabilizer device comprises a fin shaft, a fin stabilizer fixedly installed on the fin shaft and the hydraulic device driving the fin shaft to rotate, wherein a hydraulic oil input port of the hydraulic device is in communicating connection with a valve output port of a digital valve, and a valve input port of the digital valve is in communicating connection with a pump output port of an oil pump. The marine high-reliability numerical control fin stabilizer device can accurately position a rotation angle of the fin shaft and is few in control links and low in failure rate.
Description
Technical field
The present invention relates to marine equipment, relate in particular to the improvement of hydraulic efficiency gear in ship stabilization fin apparatus.
Background technology
When boats and ships run into stormy waves in navigation process, can produce the phenomenon of lateral oscillation, the lateral oscillation of boats and ships can reduce the navigability of boats and ships, injured vessel body structure, affect equipment, the normal work of instrument, also can cause displacement of goods or clash into damaging, also can make passenger and crewman swoon, may affect its fighting capacity to combat vessel, in order to reduce the lateral oscillation of boats and ships, many colleagues conduct in-depth research, the good terms of settlement of effect is, at the turn of the bilge of boats and ships, stabilizer and control setup thereof are installed at present, control setup is made up of acquisition of signal and disposal system, by measuring the angle of boats and ships lateral oscillation, the angle of going the fin axle of controlling stabilizer to rotate around its axis in conjunction with control signal of the factor outputs such as speed of the ship in meters per second, control setup contains closed loop control system, need to measure the angle that fin axle rotates, and feed back to control setup, the accurate control of rotating to realize fin axle, in this control setup being formed by closed loop control system, controlling unit and parts thereof are more and complicated, there is the hidden danger that fault rate is high.Can accurately control at present fin axle rotational angle, and lower stabilizer peculiar to vessel and the control setup thereof of fault rate not yet there is good solution.
Summary of the invention:
For prior art above shortcomings, the object of the invention is to provide a kind of high reliability numerical control fin stabilizer peculiar to vessel, it can accurately locate fin axle rotational angle, and controlling unit is few, failure rate is low.
In order to solve the problems of the technologies described above, the scheme that the present invention solves its technical matters is: high reliability numerical control fin stabilizer peculiar to vessel, the hydraulic efficiency gear that comprises fin axle, is fixedly mounted on the stabilizer on this fin axle and drives described fin axle to rotate, 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.
Adopt after such scheme, because the hydraulic oil input port of hydraulic efficiency gear and the valve output port of digital valve are connected, 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 hydraulic efficiency gear cylinder body can be realized accurately and being controlled by digital valve, and the mode of operation of digital valve can be by computer controlled, thereby can adopt computing machine to pass through the accurate control of hydraulic efficiency gear forced stroke to realize the accurate control to stabilizer deflection angle, and simple in structure, volume is little, be convenient to install, again owing to not needing to install detection and the positioner of fin axle rotational angle, simplify the structure of control setup, thereby improve 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 rotarilys actuate also opening and shutting off of control figure valve core by the output shaft of stepping motor.
Described digital valve is opening and shutting off by the reciprocating driving of ball-screw control figure valve core by stepping motor.
Described digital valve drives also opening and shutting off of control figure valve core by electromagnet apparatus.
Brief description of the drawings:
Below in conjunction with the drawings and specific embodiments, the present invention's high reliability numerical control peculiar to vessel fin stabilizer is further described.
Fig. 1 is the structural principle schematic diagram of the present invention's high reliability numerical control peculiar to vessel fin stabilizer.
Detailed description of the invention:
In Fig. 1, high reliability numerical control fin stabilizer peculiar to vessel, the hydraulic efficiency gear 7 that comprises fin axle 8, is fixedly mounted on the stabilizer 9 on this fin axle 8 and drives described fin axle 8 to rotate, 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 and the valve output port of digital valve 45 are connected, 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 and being controlled 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 the accurate control of hydraulic efficiency gear 7 forced strokies to realize the accurate control to stabilizer 9 deflection angles, and simple in structure, volume is little, be convenient to install, again owing to not needing to install detection and the positioner of fin axle rotational angle, simplify the structure of control setup, thereby improve the reliability of control setup.
