Abstract
The invention relates to the field of design of aero-engine spray pipes and backwards pushing devices, and provides a spray pipe with a backwards pushing function. The rectangular spray pipe is backwards pushed. Each external outlet of the spray pipe is provided with a rotatable adjusting piece through a rotating shaft, and the area of each adjusting piece is equal to the area of the corresponding external outlet; an actuating cylinder drives the adjusting pieces to rotate around the rotating shafts through a pull rod, each external outlet can be wholly shielded when the corresponding adjusting piece rotates to a preset position, and therefore the backwards thrust is produced, the effect of backwards pushing the rectangular spray pipe through the backwards pushing effect is achieved, practicability is high, and the application range is wide.

The technical scheme is that：It is a kind of with the anti-jet pipe for pushing away function, including rectangular nozzle body, by two pieces vertically
Side plate and at least four pieces horizontal plates are constituted, and the import of the rectangular nozzle body, outlet shapes are rectangle, and gas channel is divided into two
The individual identical and outer culvert that is distributed up and down and positioned at two contain outward between intensions, also including pressurized strut, adjustment sheet and pull bar；
Each described outer culvert exit is provided with the adjustment sheet by a rotating shaft, and the adjustment sheet is equal with the rotating shaft
Perpendicular to described two blocks vertical side plates, the adjustment sheet around the axis of rotation, and per adjustment sheet area described in block and an institute
State the outer area equation for containing outlet；
The pressurized strut includes four, and one group of two of which is hinged on the homonymy of the rectangular nozzle body cylinder, and together
Two of side pressurized struts distribution symmetrical above and below；
The drive end of the pressurized strut of homonymy is hinged with one end of the pull bar, the other end of the pull bar and the tune
The roller end of nodal plate is fixedly connected.
Alternatively, one end of one end of the pressurized strut and the pull bar is by hinge, the axis of the bearing pin with
The shaft parallel of adjustment sheet.
Alternatively, the quantity of the pull bar is four, and one group of two of which is arranged in the same of the rectangular nozzle body cylinder
Side, each described pull bar are hinged with a pressurized strut respectively；
Two pull bars positioned at two upper lateral parts are connected with the adjustment sheet of same upper lateral part respectively, under both sides
Two pull bars in portion are connected with the adjustment sheet of same side lower part respectively.
It is an advantage of the current invention that：The present invention's has the anti-nozzle structure for pushing away function simple, the start of rectangular nozzle both sides
Cylinder can realize the regulation moved to adjustment sheet by pull bar, realize the repulsion of rectangular nozzle, and practical, purposes is wide
General, to realizing rectangular nozzle repulsion effect is significant.
Description of the drawings
During accompanying drawing herein is merged in description and the part of this specification is constituted, show the enforcement for meeting the present invention
Example, and be used for explaining the principle of the present invention together with description.
Fig. 1 present invention has axonometric chart during a kind of state of the anti-jet pipe for pushing away function；
Fig. 2 the present invention have it is counter push away function jet pipe another kind state when axonometric chart.
Specific embodiment
Here in detail exemplary embodiment will be illustrated, its example is illustrated in the accompanying drawings.Explained below is related to
During accompanying drawing, unless otherwise indicated, the same numbers in different accompanying drawings represent same or analogous key element.
As shown in Figure 1 to Figure 2, it is of the invention with the anti-jet pipe for pushing away function, can realize that the counter of rectangular nozzle pushes away.Jet pipe
Rectangular nozzle body 1 can be included, be made up of two blocks of vertical side plates and at least four pieces horizontal plates, concrete closure is no longer gone to live in the household of one's in-laws on getting married
State；The import of rectangular nozzle body 1, outlet shapes are rectangle；Jet pipe also includes gas channel, be divided into two it is identical and divide up and down
The outer culvert (i.e. gas channel) of cloth and positioned at two outward contain between intensions (i.e. gas channel).
Jet pipe also includes pressurized strut 2, is arranged on the outside of vertical side plate by bolted splice.The number of pressurized strut 2 is four, its
In two bond pads 1 cylinder of rectangular nozzle body homonymy, and two pressurized struts, 2 distribution symmetrical above and below of homonymy.
Jet pipe also includes adjustment sheet 3；Each outer exit of containing arranges one piece of area with the outer area equation for containing outlet
Adjustment sheet 3, and adjustment sheet 3 is perpendicular to two blocks of vertical side plates.It should be noted that adjustment sheet 3 can turn in several ways
Arrange dynamicly and contain exit outside, in the present embodiment, be the rotating shaft connect setting by perpendicular to vertical side plate, rotating shaft can
To be wherein one long side of adjustment sheet 3, adjustment sheet 3 can rotate around the axis；Further, in the vertical of rectangular nozzle body 1
The axle of vertical bearing pin (each side plate two, distribution symmetrical above and below), the axis of bearing pin and the rotating shaft of adjustment sheet 3 is set on side plate
Line is parallel, 3 axial end portion of adjustment sheet be fixedly connected with bearing pin so that adjustment sheet 3 can be rotated around bearing pin, concrete structure is no longer
Repeat.
The present invention include upper and lower outer culvert, therefore adjustment sheet 3 including two, distribution symmetrical above and below that is to say upper and lower
Outer culvert exit is respectively provided with an adjustment sheet 3, can block outer culvert outlet when adjustment sheet 3 turns to certain angle completely so that
In outer culvert passage, gas is returned, and realization is counter to push away function.In addition, when counter pushing away, adjustment sheet 3 can turn to outer culvert with it is interior
At cylinder between culvert pipe body, and it is close to the cylinder, reducing affects.
Jet pipe also includes pull bar 4, and the quantity of pull bar 4 is four.Wherein, 4 one groups of two pull bars are arranged in rectangular nozzle body 1
The homonymy (outside of one of vertical side plate) of cylinder, one end of each pull bar 4 respectively with a pressurized strut 2 (its drive end)
It is hinged, the other end of pull bar 4 is fixedly connected to drive adjustment sheet 3 to rotate around bearing pin with the bearing pin of adjustment sheet 3.Specifically, it is located at
Two pull bars 4 of two upper lateral parts are connected with the adjustment sheet 3 of same upper lateral part respectively, and two pull bars 4 positioned at two side lower parts are distinguished
It is connected with the adjustment sheet 3 of same side lower part.
The present invention the operation principle with the anti-jet pipe for pushing away function be：
Gas Jing after the parts such as compressor, turbine, combustor, enters rectangular nozzle by inside and outside culvert, from rectangular outlet
Discharge and produce thrust.When the pressurized strut 2 of 1 both sides of rectangular nozzle body is moved, by pull bar 4 to 3 generation effect of adjustment sheet, make
Obtain the bearing pin rotation that pull bar 4 and adjustment sheet 3 can be on cylinders.Adjustment sheet 3 can be entirely outer when turning to precalculated position
Contain outlet to block, so as to produce contrary thrust, play repulsion.
The above, the only specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, any
Those familiar with the art the invention discloses technical scope in, the change or replacement that can be readily occurred in all are answered
It is included within the scope of the present invention.Therefore, protection scope of the present invention with the scope of the claims should be
It is accurate.
