, arranging a second main oil tank mounting seat at the joint of the main oil tank and the consumption oil tank, and arranging a second main oil tank mounting seat connected with the wings of the unmanned aerial vehicle on the side of the main oil tank relative to the consumption oil tank;
, the oil consumption tank is provided with an oil return port communicated with the engine for returning oil;
, arranging a consumed oil tank swash plate for slowing down oil shake at the position, opposite to the oil return port, of the consumed oil tank;
, arranging a plurality of swash plates for slowing down oil movement in the main oil tank;
the invention has the beneficial effects that: the oil tank is arranged in the wing, so that the capacity is not limited any more, and the volume can be increased; the main oil tank of the oil tank is arranged on two sides of the machine body, the volume of the consumed oil tank is small, the consumed oil tank does not occupy too large space of the machine body, and the middle section of the whole machine body can be arbitrarily provided with load equipment.

Detailed Description
The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the invention.
As shown in FIG. 1, a gravity type split oil tank for small unmanned aerial vehicles comprises a consumption oil tank 17 communicated with an unmanned aerial vehicle engine and two main oil tanks 1 (only the main oil tank on the side is shown in FIG. 1, the main oil tank on the other side is symmetrical with the main oil tank and is not shown) positioned on the upper sides of the two sides of the consumption oil tank 17, a main oil tank oil outlet 8 of each main oil tank is communicated with a consumption oil tank oil inlet 11 of the consumption oil tank through a connecting pipe 15, an oil filling port 6, a through air port 5 and a consumption oil tank communication port 7 are arranged on the upper side of each main oil tank, close to the side of the consumption oil tank, a main oil tank communication port 9 is arranged right above the consumption oil tank, the main oil tank communication port is communicated with the consumption oil tank communication port through a second connecting pipe 16, and a consumption oil tank;
when the oil pumping device is specifically implemented, the atmosphere pressure in the main oil tank and the atmosphere pressure in the consumed oil tank can be ensured to be the same by arranging the vent hole, the main oil tank communicating port and the consumed oil tank communicating port, oil in the main oil tank positioned above the vent hole can be slowly supplemented into the consumed oil tank along with the consumption of the consumed oil tank under the action of gravity, and a high-pressure pump does not need to be arranged in a split oil tank for pumping oil as in the prior art;
in specific embodiments, a second main oil tank mounting seat 4 is arranged at the joint of the main oil tank 1 and the consumption oil tank 17, and a main oil tank mounting seat 2 connected with the wing of the unmanned aerial vehicle is arranged on the side of the main oil tank relative to the consumption oil tank;
in another embodiments, the consumption oil tank is provided with an oil return port 18 for returning oil, which is communicated with the engine;
more specifically, a consumed oil tank wave-preventing plate 14 for slowing down oil shaking is arranged at a position, right opposite to the oil return port, of the consumed oil tank, so that the situation that the flight control is influenced by the random shaking of the oil in the oil tank is prevented;
the whole process of oil filling, oil discharging and oil returning is described by combining the specific structure described above:
refueling: refuel through the oil filler hole on the main tank, use the three-way pipe to refuel to two main tanks simultaneously when refueling, the oil that adds gets into through the main tank oil-out and consumes the oil tank, along with adding the increase of oil mass, the liquid level that consumes the oil tank flushes with the main tank liquid level, and finally, consumes the oil tank and reaches maximum position with the main tank simultaneously.
Oil production: the oil enters the engine for use only through the oil outlet of the consumption oil tank. Along with the consumption of gasoline, the liquid level of the consumed oil tank is lower than that of the main oil tank, so that the oil in the main oil tank enters the consumed oil tank through the oil outlet of the main oil tank under the action of gravity.
Oil return: redundant oil of the engine enters the oil tank again through an oil return port of the consumed oil tank, and a swash plate is added to prevent the return oil from impacting the oil quantity sensor.
When the airplane is in different postures, in order to prevent oil from shaking randomly in the oil tank (the flying control is influenced by too much shaking), a plurality of wave guards 3 for slowing down the movement of the oil are arranged in the main oil tank;
the whole oil tank is only provided with an oil consumption tank for communicating with the engine to supply oil, and the oil consumption tank is provided with an oil mass sensor 10 for detecting the oil mass.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
