Description
Technical field
The utility model relates to flight equipment technical field, is specifically related to a kind of unmanned plane fuel-feed system.
Background technology
The fuel-feed system of unmanned plane comprises fuel tank, fuel feed pipe and carburettor, fuel tank and carburettor are connected into oil supply loop by fuel feed pipe, and carburettor is a very crucial equipment, if having bubble in carburettor, the fluid entering carburettor engine off will be caused, so can not have bubble in you.The fuel-feed system kind of tradition unmanned plane does not arrange the device getting rid of bubble in fluid, and this can make the range of use of unmanned plane be subject to restriction; And when in fuel tank, Fuel Oil Remaining is not many, unmanned plane can not complete some highly difficult actions, and this also further limit the range of use of unmanned plane.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of novel in design, and flexible operation is easy, effectively can discharge the unmanned plane fuel-feed system of bubble in fuel tank inner fluid.
For solving the problems of the technologies described above, the utility model provides following technical scheme: a kind of unmanned plane fuel-feed system, comprise fuel tank, fuel feed pipe, carburettor, vacuum tank, control box, fuel feed pipe connects fuel tank and carburettor, fuel tank is provided with oil filling port, control box is arranged on fuel tank, vacuum pump is provided with in described vacuum tank, tracheae is provided with between described vacuum pump and fuel tank, the top of described fuel tank is provided with oil separating plate, oil separating plate is provided with breather hole, the lower surface of oil separating plate scribbles and hates oil-based paint layer, the tracheae end stretched in fuel tank is arranged on the top of oil separating plate, described oil separating plate is provided with the through hole being suitable for fuel feed pipe, level sensor is provided with in described fuel tank, level sensor and control box are electrically connected, described level sensor is arranged on the below of oil separating plate, fuel tank is also provided with air inlet pipe, air inlet pipe is provided with intelligent valve, described intelligent valve and control box are electrically connected.
The beneficial effect that the utility model compared with prior art has is: the utility model is novel in design, structure rationally, effectively can discharge the bubble in fuel tank inner fluid, guarantee that the oil quality entered in fuel feed pipe carburettor is high, flame-out phenomenon occurs because importing bubble effectively to avoid driving engine.
Accompanying drawing explanation
Fig. 1 is the utility model integral structure schematic diagram.
Number in the figure is: 1-fuel tank, the filter of 2-oil, 3-carburettor, 4-fuel feed pipe, 5-oil hammer, 6-oil separating plate, 7-vacuum tank, 8-air inlet pipe, 9-intelligent valve, 10-level sensor, 11-control box.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
In description of the present utility model, it will be appreciated that, term " longitudinal direction ", " transverse direction ", " on ", D score, " front ", " afterwards ", " left side ", " right side ", " vertically ", " level ", " top ", " end ", " interior ", orientation or the position relationship of the instruction such as " outward " are based on orientation shown in the drawings or position relationship, it is only the utility model for convenience of description, instead of indicate or imply that the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
Known with reference to Fig. 1, a kind of unmanned plane fuel-feed system, comprise fuel tank 1, fuel feed pipe 4, carburettor 3, vacuum tank 7, control box 11, fuel feed pipe 4 connects fuel tank 1 and carburettor 3, fuel tank 1 is provided with oil filling port, control box 11 is arranged on fuel tank 1, vacuum pump is provided with in described vacuum tank, tracheae is provided with between described vacuum pump and fuel tank 1, the top of described fuel tank 1 is provided with oil separating plate 6, oil separating plate 6 is provided with breather hole, the lower surface of oil separating plate 6 scribbles and hates oil-based paint layer, the tracheae end stretched in fuel tank 1 is arranged on the top of oil separating plate 6, described oil separating plate 6 is provided with the through hole being suitable for fuel feed pipe 4, level sensor 10 is provided with in described fuel tank 1, level sensor 10 and control box 11 are electrically connected, described level sensor 10 is arranged on the below of oil separating plate 6, fuel tank 1 is also provided with air inlet pipe 8, air inlet pipe 8 is provided with intelligent valve 9, described intelligent valve 9 is electrically connected with control box 11, fuel feed pipe 4 end stretched in fuel tank 1 is provided with oil hammer 5, be provided with oil filter 2 in described oil filling port, can guarantee like this to enter containing less impurity in the fluid in fuel tank 1, and oil filter 2 is arranged in oil filling port and is convenient to change.When oil dropping apparatus 1 refuels, first open level sensor 10, the stop control lever when fluid is added to the height of level sensor 10 regulation also closes oil filling port, the intelligent valve 9 on air inlet pipe 8 is now closed by control box 11, then vacuum pump is opened, utilize the bubble in vacuum pump extraction fuel tank 1 inner fluid, oil-based paint layer is hated due to oil separating plate 6 scribbling, fluid in fuel tank 1 can not enter in vacuum pump by suck-back, after the bubble in fluid is discharged, open intelligent valve 9 again, outside air is made to enter in fluid, because the bubble in fluid is discharged, enter in the fluid in carburettor 3 and there will be no bubble.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
