Description
Technical field
The utility model is related to a kind of steering engines.Specifically, it is peculiar to vessel on rudder for controlling turning to for ship running direction
Frequency conversion steering engine.
Background technology
Currently, for control ship running direction turn to rudder on steering engine for ship mainly by motor, hydraulic power unit and turn
Steering engine structure forms.When work, power is provided to drive hydraulic power unit to work for hydraulic power unit by motor, the liquid that hydraulic power unit provides
Pressure oil, which by control valve group commutate etc., enters the mechanism that comes about after operation, and the oil return opening for the mechanism that comes about passes through oil pipe and hydraulic oil
Case is connected to.It can be seen that the hydraulic power unit of this mechanism peculiar to vessel that comes about is using open type hydraulic system, the i.e. liquid of oil pump offer
Pressure oil by control valve group commutate etc. enter the mechanism that comes about after operation after, then hydraulic oil flowed back to by the oil return opening for the mechanism that comes about
In case.Since above-mentioned steering engine is using open type hydraulic system, huge hydraulic power unit is needed, not only occupied space is more,
And for valve control commutate so that whole system it is less efficient, energy consumption is larger.
Utility model content
Problem to be solved in the utility model is to provide a kind of frequency conversion steering engine peculiar to vessel.Using the utility model, can not only subtract
Few occupied space improves efficiency, can also reduce energy consumption.
The above problem to be solved in the utility model is realized by following technical scheme：
The frequency conversion steering engine peculiar to vessel of the utility model includes motor, oil pump, control valve group, the mechanism that comes about and controller, described
The mechanism that comes about contains cylinder body, has rotor in cylinder body, has oil inlet and outlet on the casing wall of cylinder body.The controller is by conducting wire and electricity
Machine is connected with the mechanism that comes about, and the output shaft of motor is connected with the input shaft of oil pump.Its main feature is that the motor is variable-frequency motor, institute
It is two-way pump to state oil pump, and a pumping hole of two-way pump is connected by control valve group with an oil inlet and outlet of cylinder body, another pump
Mouth is connected to another oil inlet and outlet of cylinder body.
Further improvement of the utility model scheme be further include pressurized fuel tank, pressurized fuel tank is connected to control valve group.
Further improvement of the utility model scheme is the integrated peace of the motor, oil pump, control valve group and pressurized fuel tank
In the mechanism that comes about.
Since the motor is variable-frequency motor it can be seen from above scheme, the oil pump is two-way pump, the one of two-way pump
A pumping hole is connected by control valve group with an oil inlet and outlet of cylinder body, another oil inlet and outlet of another pumping hole and cylinder body connects
It is logical.When needing to come about to a direction, two-way pump rotation is driven under the driving of variable-frequency motor, by a pumping hole of two-way pump
Pressure oil is provided for system, to drive the mechanism that comes about that rudderpost and rudder for ship is driven to be rotated to a direction.At the same time, two-way
While one pumping hole of pump provides pressure oil for a hydraulic fluid port of the mechanism that comes about, the liquid of another hydraulic fluid port discharge for the mechanism that comes about
Pressure oil is passed back into again in another pumping hole of two-way pump.Vice versa.It can be seen that a hydraulic fluid port of two-way pump and the mechanism that comes about
Between, a closed circuit is formed between another hydraulic fluid port for the mechanism that comes about and another pumping hole of two-way pump so that the utility model
Hydraulic system used is closed type hydraulic system.In this way, eliminating larger hydraulic oil container, only a smaller pressurised oil need to be set
Case is that system supplements hydraulic oil.Compared with the background art, the occupied space of system is greatly reduced.Due to the utility model
The motor used is variable-frequency motor, and two-way pump is coordinated to come flow and the direction of control system pressure oil, is used with background technology
Valve control is compared, and is not only substantially increased the efficiency of system, is also reduced energy consumption.
Description of the drawings
Fig. 1 is the frequency conversion steering engine principle schematic peculiar to vessel of the utility model；
Fig. 2 is the frequency conversion steering engine structural schematic diagram peculiar to vessel of the utility model.
Specific implementation mode
As depicted in figs. 1 and 2, the frequency conversion steering engine peculiar to vessel of the utility model contains motor 2, oil pump 3, control valve group 4, comes about
Mechanism 6 and controller 1, the mechanism 6 that comes about contain cylinder body 66, rotor are provided in cylinder body 66.Cylinder body 66 therein contains one
The upper and lower side of a round cylinder, circle cylinder is both provided with cylinder cap, and the center of cylinder cap is machined with axis hole.The rotor contains shaft 67, turns
The upper and lower side of axis 67 is respectively protruding into the axis hole that respective barrel covers.Wherein, 67 lower end of shaft is connected with rudder for ship.The shaft 67
Three blades 68 are uniformly distributed on peripheries with, a vertical edge of blade 68 is connected with shaft 67, another vertical edge and the circle cylinder of blade 68
Inner circle between, blade 68 it is upper below between corresponding cylinder cap be in seal shape activity coordinate.The inner circle surrounding of the round cylinder is equal
There are three axial projections 69 for cloth, coordinate in seal shape activity between the inner raised edge and shaft 67 of axial projection 69.On the casing wall of circle cylinder
It is machined with oil inlet and outlet.The output shaft of the motor 2 is connected with the input shaft of oil pump 3.The motor 2 is variable-frequency motor, described
Oil pump 3 is two-way pump, and a pumping hole of two-way pump is connected by control valve group 4 with an oil inlet and outlet of cylinder body 66, another
Pumping hole is connected to another oil inlet and outlet of cylinder body 66.The controller 1 is connected by conducting wire with motor 2 and the mechanism 6 that comes about.
For ease of supplementing pressure for system, it is additionally provided with pressurized fuel tank, which passes through pipeline, valve and control valve
Group connection.
As shown in Figure 1, to further reduce the volume of the utility model, occupied space, the motor, oil pump, control are reduced
Valve group processed and the equal integrated installation of pressurized fuel tank are being come about in mechanism.
When needing to come about to a direction, two-way pump rotation is driven under the driving of variable-frequency motor, by the one of two-way pump
A pumping hole provides pressure oil for system, to drive the mechanism that comes about that rudderpost and rudder for ship is driven to be rotated to a direction.At the same time,
While a pumping hole of two-way pump provides pressure oil for a hydraulic fluid port of the mechanism that comes about, another hydraulic fluid port for the mechanism that comes about is arranged
The hydraulic oil gone out is passed back into again in another pumping hole of two-way pump.Vice versa.
