Description
Technical field
The invention belongs to power management technical field, it is related to a kind of manipulation machine of control engine choke aperture
Structure.
Background technology
Country's unmanned plane just starts development in recent years at present, because China's unmanned plane manipulation technology is started late, and
The technology of various countries' this respect is not also announced externally, how to stablize, reliably transmission manipulation information be directly connected to nothing
Man-machine overall performance, thus instantly China in the urgent need to improve unmanned plane research and development, production, using etc. technology water
It is flat.If the manipulation technology of unmanned plane can not be grasped well, this can directly affect the reliability of unmanned plane and go out
Diligent rate, greatly improves the maintenance cost of unmanned plane.
The content of the invention
The technical problem to be solved in the present invention：
The engine that unmanned plane is selected is piston-mode motor, and piston-mode motor has starting failure when starting
The problem of.Fuel oil is set to enter engine vaporizer, it is necessary to open engine oil path when engine needs to start
In, while being started for the ease of engine, it is necessary to control choke aperture.The effect of choke is regulation air
Inlet, when the concentration that engine oil gas is mixed reaches certain proportion, the success rate that engine is started is very
Height, therefore the size of control choke aperture is that engine starts successful key.
Technical scheme：
A kind of operating mechanism of control engine choke aperture, including choke gear 1, manipulation cable wire 2 and
Ring pull mechanism 3, the ring pull mechanism 3 is fixed on structure deckle board, manipulates the one end of cable wire 2 and ring pull mechanism
3 connections, the other end is connected with choke gear 1, and when engine needs to start, draw ring 11 is pulled first,
At this moment ring pull mechanism 3 can be driven manipulation cable wire 2 to move by the effect of external force, while being connected with manipulating cable wire 2
Choke Rocker arm 4 will with choke rocking arm rotary shaft 5 be axle center be rotated, so as to realize to engine
The control of choke aperture.
Back-moving spring 17 is connected with the choke Rocker arm 4, after engine start, choke Rocker arm 4
Resetted in the presence of back-moving spring 17.
The ring pull mechanism 3 is by cable connector 10, draw ring 11, manipulation fixed support 12, nut 13, cable wire
Sheath 14, screw 15, self-locking nut 16 are constituted, and are manipulated fixed support 12 and are riveted on aircaft configuration web
On, draw ring 11 is fixed on manipulation fixed support 12 and fastened by self-locking nut 16 and screw 15, cable wire
Joint 10 is connected with draw ring 11 and fastened by nut 13 with three through holes, middle macropore, both sides
Aperture manipulates the circular bulb of cable wire 2 with two and is connected, and cable wire sheath 14 is fixed on manipulation fixed support 12,
It can play a part of being abrasionproof and guiding, and draw ring 11 drives two manipulation steel by the cable connector 10
Rope 2 is moved, and controls engine both sides choke Rocker arm 4 to rotate respectively.
Beneficial effects of the present invention：
The engine control that the present invention is provided can be realized to engine choke aperture in aircraft exterior
Control.Mechanism is mechanical part simultaneously, and dismounting/installation is simple.Be not in due to software systems error
Cause the problem of engine can not be started.
