Detailed description of the invention
Fig. 1 is single structure schematic diagram of the invention, in which: graininess brass material oil hammer in a kind of (a) embodiment,
(b) it is rubber hose, (c) is semi-circular high-density resin fuel tank；
Fig. 2 is the overall structure diagram that the present invention realizes its function；
Fig. 3 is graininess brass material oil hammer schematic diagram in another embodiment of the present invention.
Wherein: 1 is fuel tank；2 be oil hammer；3 be fuel feed pump；4 be oil return pipe.
Specific embodiment
The invention will be described in further detail with reference to the accompanying drawing:
Referring to Fig. 1 and Fig. 2: the unmanned plane oil storage system that Anti-inclining of the invention shakes, including fuel tank 1 and setting are in oil
Oil hammer 2 in case 1, the oil hammer 2 are connected to the engine oil mouth outside fuel tank 1 by fuel feed pump 3, in the fuel tank 1 also
It is provided with the oil return pipe 4 connecting with engine and carburetor；Fuel tank 1 is semi-circular fuel tank；Oil hammer 2 includes oil nozzle 2.3, oil nozzle 2.3
Lower end be fixedly connected with terminal pad, the downside of terminal pad is connected with the pendant 2.1 as made of several metallic particles bonding；
Fuel feed pump 3 and oil return pipe 4 are rubber hose, and fuel feed pump 3 protrudes into the bottom of fuel tank 1 and is connected on oil nozzle 2.3.
As shown in Fig. 1 (c): fuel tank 1 is the semi-circular high-density resin fuel tank that lower part is divided into dome-type, the fuel tank 1
The avris of 1 upper surface of fuel tank is arranged in oil filler.The bottom setting of fuel tank 1 is fluted.The upper surface of fuel tank 1 is plane, in oil
The side of case 1 is provided with the fixed bracket 1.1 of the fuel tank for connecting aircraft.Fuel tank 1 of the invention uses high density epoxy resin
Material effectively prevent the infiltration and corrosion of gasoline.Hemispherical is used in shape, and more conducively fuel oil and oil hammer inclines with aspect
It tiltedly shakes and changes position, hemispherical can increase sky into utilization rate, in the fuel tank of same weight classes, reach volume maximization.
The setting of fuel tank oil inlet can prevent fuel oil from being splashed out when aircraft shakes and come in upper surface, while improve the convenient function of oiling
Energy.There are tank bottoms using groove shapes, very big limit reduces dead oil amount.
Such as Fig. 1 (b): oil pipe (fuel feed pump and oil return pipe) of the invention uses rubber hose, when craft inclination shakes, oil
Pipe can guarantee that oil hammer slidably reciprocates without by external force, because liquid will receive gravity factor, with the variation of craft inclination posture
And change location guarantees that oil hammer can touch liquid always so oil hammer also will be slided and then.Such as scheme totally two hoses, one
It is engine oil pipe, another is engine oil return pipe.Hose uses epoxide resin material, and effective oil resistant is corrosion-resistant.Hose
It can guarantee that oil hammer is not influenced when slidably reciprocating in fuel tank with aspect variation by external force.Effectively always by gravity
Influence touches fuel oil.It prevents engine and does not oil and stop working because inhaling.
The pendant 2.1 of oil hammer 2 of the invention is formed by several brass particles are viscous.Implement in one of which of the invention
In example, as shown in Fig. 1 (a): connector is a round terminal pad 2.2.1, and the upper end of pendant 2.1 is connected to round terminal pad
2.2.1 downside.Pendant 2.1 is bonded as round estrade structure by brass particle, makes pendant 2.1 after each brass particle bonding
Form sponge effect.Pendant 2.1 can reduce the frictional force of oil hammer from shape and surface smoothness, enable oil hammer in fuel tank
It is interior freely to roll.
In another embodiment of the invention, described tapered as shown in figure 3, connector is tapered copper sheathing shell 2.2.2
It is partially cone on barrel housing 2.2.2, lower part is drum；2.1 top of pendant stretches to tapered copper sheathing shell
2.2.2 interior.The upper part of tapered copper sheathing shell 2.2.2 is cone, and lower part is drum-shaped；The pendant 2.1 is by brass
Particle is bonded as bullet-shaped structure.The brass particle diameter wrapped up in tapered copper sheathing shell 2.2.2 is 2.1 lower half of pendant
Divide the half of exposed brass particle diameter.2.1 lower half portion particle wide arc gap of pendant in the present embodiment is big,
Top half gap is small, and lower half portion is conducive to fuel oil absorption, and top half is conducive to exclude bubble, filters fine impurities.Under
The tapered shell structure of hypophysis 2.2, shell lower half portion is drum, and particle is effectively prevent to fall off, top half cone, increasingly
Small section is effectively expelled from residual bubble and impurity.The oil nozzle 2.3 and connector of oil hammer 2 are an entirety, and connector is tapered
Shell structure, shell lower half portion are drums, and particle is effectively prevent to fall off, and top half cone, smaller and smaller section has
Effect is expelled from residual bubble and impurity.Oil nozzle 2.3 uses hangnail shape, and oil pipe is effectively facilitated to be inserted into and prevent from falling off.
Oil hammer 2 of the invention uses brass material, effectively prevent the corrosion and oxidation of gasoline.Oil hammer 2 uses spheric granules
It is bonded, similar foam plays the role of sponge effect, can play oil suction, invades liquid level hereinafter, only even being not all of
It wants oil hammer to touch liquid, ensures that in oil pipe without bubble, engine is effectively prevent to stop working due to not oiling because inhaling.Oil hammer 2
Aircraft lower part is connected to using suspension type using fuel tank 1 of the present invention, prevents fuel oil rotten and volatilization.Hemispherical can increase fuel tank
Volume, fuel tank lower hemispherical be conducive to simultaneously fuel oil and oil hammer with aspect tilt and slide, make oil hammer always and fire
Movement when oil keeps colluding effectively prevent oil hammer to be detached from fuel oil and bubble is caused to enter oil pipe.Hair is effectively reduced in hemispherical design
Motivation dead oil amount, as far as possible raising fuel utilization ratio, improve aircraft cruise duration, increase power to weight ratio.
Referring to fig. 2: mounting means of the invention is as follows:
Installation site: outermost is hemispherical fuel tank, and fuel tank internal is oil hammer, and oil pipe connects oil hammer and outer
It connects.
Connection type: engine is mounted on central plate lower end under body, oil hammer and engine in body the top, fuel tank
Oily device is connected by oil pipe, and oil hammer is in fuel tank internal lowermost end；
Overall work principles illustrated of the invention:
A. when engine is run, carburetor can automatically generate negative pressure, and oil hammer touches fuel oil, the negative pressure meeting of carburetor always
The fuel oil that oil hammer touches is absorbed by oil pipe, extra fuel oil can return in fuel tank from carburetor oil return pipe；
B. in flight, posture can swing back and forth aircraft, and fuel oil will receive gravity influence at this time, move back in fuel tank
It is dynamic, remain at fuel tank extreme lower position.Oil hammer can also swing with fuel oil, touch always due to being influenced by gravity
Fuel oil guarantees that fuel feeding is continuous in oil pipe.
