Description
Technical field
The present invention relates to a kind of control device of submarine navigation device, specifically a kind of non-traditional submarine navigation device
Control device.
Background technology
Thruster vector control technology is a kind of unconventional control technology, refers to that motor power passes through jet pipe or tail jet
Deflection produce thrust component come substitute former ROV control surface or strengthen ROV operating function.So-called thrust vectoring
Control refers to propulsion system in addition to providing thrust for ROV, concurrently or separately can provide driftage, rolling for ROV, bow
Required thrust is faced upward, the thrust comes from engine interior, it is no longer necessary to rudder, elevator, the mechanical device such as flank.Generally
In the case of thruster vector control technology realize that jet pipe can be divided into mechanical actuation formula Thrust-vectoring Nozzle and fixation dependent on jet pipe
Geometry pneumatic thrust vector spray.
Mechanical actuation formula Thrust-vectoring Nozzle, can meet the functional requirement of ROV substantially, but it possesses the machine of complexity
Tool structure, according to statistics, the weight of mechanical actuation formula Thrust-vectoring Nozzle is 25% or so of whole propulsion system, adjustment sheet, close
More than 1,000 part such as mounting, executing agency is used to implement thruster vector control, it is clear that considerably increase the weight of propulsion system
And complexity, the reliability of system is reduced, while the maintenance and cost Control to ROV are very unfavorable.With thrust vectoring
The development of technology, the concept of fluid thrust vector control nozzle is suggested, and this jet pipe is totally different from mechanical actuation formula thrust
Vector spray, it influences the motion state of main fluid, so as to control main flow area by entering fluid in nozzle divergence cone secondary injection
And direction, reach the purpose of thruster vector control.The technology depends on fixed geometry pneumatic thrust vector spray to realize, it is tied
Structure is simple, simplifies substantial amounts of mechanical movement part, alleviates the weight of ROV, reduce cost, has ROV stronger
Mobility and super maneuverability.But a secondary fluid injected at present typically from ROV in itself, structure is more complicated.
The content of the invention
It is an object of the invention to provide one kind is simple in construction, realized using the water in external environment to submarine navigation device
The secondary water spray thruster vector control device of thruster vector control.
The object of the present invention is achieved like this：
Including fixed plate, filling pipe, flow control valve, fixed plate is fixed on the expansion segment of jet pipe, and fixed plate will supply water
Pipeline is connected with jet pipe, and the groove that secondary water spray is injected to nozzle divergence cone, the water inlet position of water supply line are opened up in fixed plate
Communicate in the front of submarine navigation device and with external environment, flow control valve is arranged on water supply line, fixed plate expands with jet pipe
Opening section contact position has sealing system.
The invention provides the secondary water spray thruster vector control device of one kind, by simple and effective structure, the external world is utilized
Water in environment, realizes the thruster vector control to submarine navigation device.
The device of invention is made up of jet pipe, fixed plate system, the adjustable water system of flow and sealing system.By fixed plate
System is fixed on the expansion segment of jet pipe, and water supply line is connected by fixed plate with jet pipe, fixed plate internal recessing, and secondary water spray is penetrated
Enter nozzle divergence cone；Water-jet in external environment is entered nozzle divergence cone by water system by pipeline, and valve is installed on pipeline
For controlling the mass flow of secondary water spray, by different water injection rates, to reach different thruster vector control effects；Sealing
System is used between fixed plate and filling pipe and jet pipe, prevents leakage.
Secondary water spray is injected after nozzle divergence cone, and it acts on the supersonic flow of nozzle divergence cone, due to doing for jet
Relate to principle and oblique shock wave is produced in nozzle gas flow, cause the pressure distribution in jet pipe uneven so that the jet in exit occurs
Deflection, so as to produce required side force and torque.
The beneficial effects of the invention are as follows：By the use of the water in external environment as the fluid of secondary injection, submarine navigation device is not
Need to carry the device that a secondary fluid storage bin, high-pressure pump etc. are used to complete fluid secondary injection, simplify secondary injection mode,
Fluid secondary injection is simple and convenient；The apparatus structure is simple, without complicated mechanical servo, to the controlling party of thrust vectoring
Just, the system response control instruction time is short, and response is fast, and control efficiency is higher, improves the mobility of submarine navigation device；Realization is pushed away
Enter the integration of control, system whole pneumatic control reduces underwater navigation resistance；Secondary water spray can partly take into account nozzle-divergence
The cooling of section, jet pipe wall surface temperature significantly declines, and while protection nozzle structure, jet pipe infra-red radiation can again reduced, is carried
The stealth of high ROV.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
The present invention is elaborated with reference to Structure Figure citing.
With reference to Fig. 1, the invention includes jet pipe 1, fixed plate system 2, sealing system 3, filling pipe 4 and flow control valve
5。
Filling pipe 4 is fixed on the expansion segment of jet pipe 1, the air-tightness of the holding meanss of sealing system 3 through fixed plate system 2.
When the device is operated, submarine navigation device is navigated by water along a direction, and the water in external environment by leaking in extraneous water environment cruelly
Pipeline 4 enters thruster vector control device, according to required thruster vector control requirement, by flow control valve 5, obtains
The secondary water spray of certain mass flow, secondary water spray is via filling pipe 4, and the jet flow groove 6 for being incorporated into fixed plate system injects spray
The expansion segment of pipe 1, secondary water-jet acts on the supersonic flow of nozzle divergence cone, due in the interference effect jet pipe 1 of jet
Oblique shock wave is produced, the air-flow in jet pipe 1 is deflected, so as to complete thruster vector control, adjusts secondary by flow control valve 5
The mass flow of water spray, can control the size of thrust vectoring.
