Brief description of the drawings
Accompanying drawing herein is merged in specification and forms the part of this specification, show meet it is of the present utility model
Embodiment, and for explaining principle of the present utility model together with specification.
Fig. 1 is that the parallel inlet central body of the embodiment of the utility model one moves schematic diagram.
Fig. 2 is the parallel inlet central body structure decomposition figure of the embodiment of the utility model one.
Reference：
Air intake duct under 100-, 200- fixed structures, the enterprising air flues of 300-；
1- adjustment structures, 2- drive mechanisms, 3- rotating shafts, the upper adjustable plates of 11-, adjustable plate under 12-.
Embodiment
To make the purpose, technical scheme and advantage that the utility model is implemented clearer, below in conjunction with the utility model
Accompanying drawing in embodiment, the technical scheme in the embodiment of the utility model is further described in more detail.
As shown in Figure 1 schematic diagram, this practicality are moved for the parallel inlet central body of the embodiment of the utility model one
New parallel inlet central body includes adjustment structure 1 and drive mechanism 2, and the first end of adjustment structure 1 is articulated with admittedly
Determine structure 200, the second end of adjustment structure 2 is connected with drive mechanism 2, the other end of drive mechanism 2 also with fixed structure 200
Or the other structures connection of aircraft, for making drive mechanism 2 be fixed relative to fixed structure 2, enabled to by drive mechanism 2
Adjustment structure 1 rotates around the hinge of first end, to adjust the charge flow rate of enterprising air flue 300 or lower air intake duct 200, reference picture 1
Middle dotted line be adjustment structure 1 in the presence of drive mechanism 2, adjustment structure 1 blocks position during enterprising air flue 300.
In embodiment of the present utility model, drive mechanism can be the devices such as pressurized strut, motor.
In preferred embodiment of the present utility model, adjustment structure 1 is into triangle.The adjustment structure 1 of triangle is it
Middle both ends are connected with fixed structure 200 close to the position of lower air intake duct 100 and enterprising air flue 300 respectively, so that triangle
Two faces of shape adjustment structure can be connected with up/down air intake duct so that flow through the air-flow of up/down air intake duct along two
Surface current moves.
Therefore, in preferred embodiment of the present utility model, the first face of adjustment structure 1 and enterprising 300 round and smooth mistake of air flue
Cross, and the second face of adjustment structure 1 and the lower rounding off of air intake duct 100, to reduce air-flow when air-flow flows through connecting portion
Loss.
It should be noted that the rotating shaft 3 of shown adjustment structure 1 is located at close to one end of lower air intake duct 100 in Fig. 1,
And the drive end of adjustment structure 1 is located at close to one end of enterprising air flue 300, when drive mechanism 2 drives adjustment structure 1 to rotate,
Rotating shaft end is relatively fixed with the position of fixed structure 200, and position of the drive end then with fixed structure 200 relatively moves, and this just makes
The downside of air intake duct 100 and adjustment structure 1 rounding off all the time must be descended, windage loss is small, and is adjusted because drive mechanism 2 drives
When nodule structure 1 blocks lower air intake duct 100, it can be produced compared with big gap between the upper side of adjustment structure 1 and enterprising air flue 100,
Larger windage loss is caused, therefore as needed, the rotating shaft 3 of adjustment structure 1 can also be arranged in close to upper air
The one end in road 300, and the drive end of adjustment structure 1 is arranged in close to one end of lower air intake duct 100.
As shown in Fig. 2 in preferred embodiment of the present utility model, adjustment structure 1 includes upper adjustable plate 11 and lower regulation
Plate 12, upper adjustable plate 11 after the splicing of lower adjustable plate 12 with forming complete adjustment structure 1, upper adjustable plate 11 and the lower phase of adjustable plate 12
To fixation.It is equal in upper adjustable plate 11 and face that lower adjustable plate 12 contacts with each other in addition, in preferred embodiment of the present utility model
Symmetrical semi-circular lightening hole is respectively provided with, to reach the purpose of loss of weight.But advantageously, upper adjustable plate 11 is with lowering
Save plate 12 be with rib construction platy structure, it is plane (to be based on Fig. 2 positions) above upper adjustable plate 11, for pair
Enterprising air flue 300 carries out water conservancy diversion, and it is also plane (to be based on Fig. 2 positions) below lower adjustable plate 12, for entering to lower air intake duct 100
Row flows backwards, and in the inside of upper adjustable plate 11 and lower adjustable plate 12 be it is hollow, both only by structure structural support and split,
To reach the purpose of maximized loss of weight.
In preferred embodiment of the present utility model, the connected mode of drive mechanism 2 and adjustment structure 1 is be hinged so that
Drive mechanism 2 can rotate along the hinge being connected with adjustment structure 1.Further, it is preferable to carry out of the present utility model
In example, drive mechanism 2 is connected with adjustment structure 1 by single ears structure.Single ears structure is for transmitting larger power (air intake duct
Interior air-flow can produce larger impulsive force), and connected mode is simple, reliable, it is only necessary to using bolt through adjustment structure 1 with driving
Motivation structure 2 and with nut check.
Parallel inlet central body of the present utility model is can be achieved up and down using less parts in air intake duct
The regulation of flow, and parallel inlet central body of the present utility model is simple to operate, securely and reliably, disclosure satisfy that and starts
The requirement of machine.
More than, optimal embodiment only of the present utility model, but the scope of protection of the utility model is not limited to
In this, any one skilled in the art is in the technical scope that the utility model discloses, the change that can readily occur in
Change or replace, should all cover within the scope of protection of the utility model.Therefore, the scope of protection of the utility model should be with right
It is required that protection domain be defined.
