The unmanned aerial vehicle engine is generally a fuel engine, and when the unmanned aerial vehicle engine is started in a low-temperature environment, the physical performance of the unmanned aerial vehicle engine is reduced due to the influence of low temperature on liquids such as fuel oil, lubricating oil and the like in the engine, so that the engine is difficult to start. The operation of current carrying out low temperature to unmanned vehicles engine mainly relies on the manual work to carry out auxiliary mode, because the engine is installed in unmanned vehicles's engine compartment's inside, through the covering of the engine compartment that is equipped with the oil cooler cooling wind channel with the engine enclosure, therefore need dismantle parts such as the covering of engine compartment earlier before starting the engine, after changing high temperature lubricating oil, carry out the disk oar again and start many times, after the start is accomplished again with spare part assembly reduction, such operation is both wasted time and energy, and carry out quick dismouting to spare part under low temperature environment, unmanned vehicles ' risk has been increased. However, the manual auxiliary starting has the advantage that the structure of the existing unmanned aerial vehicle does not need to be improved, and the influence on the use caused by the change of the performance parameters of the existing unmanned aerial vehicle is avoided.
In some special cases, it is required that the unmanned aerial vehicle must be able to lift off quickly (typically, it is required that the lift off must be started within 30 minutes), but in a low temperature environment, even if an operation of manual auxiliary starting is adopted, the starting of the engine usually takes more than 1 hour, and the starting success rate of the engine within 30 minutes is almost zero. Therefore, it is necessary to design an auxiliary device for quickly starting an engine of an unmanned aerial vehicle at a low temperature without affecting the performance parameters of the existing unmanned aerial vehicle.
Disclosure of Invention
The invention aims to provide auxiliary equipment for starting an engine of an unmanned aerial vehicle, which aims to solve the problem that the success rate of quickly starting the engine of the existing unmanned aerial vehicle at low temperature is low in the prior art.

The beneficial effect of this basic scheme lies in: when the unmanned aerial vehicle engine is started, the engine cabin is heated by adopting the scheme, so that the engine is heated in a hot environment, and the success rate of successful starting of the engine within 30 minutes reaches more than 80 percent.
In order to further improve the starting timeliness of the unmanned aerial vehicle engine, the air outlet pipeline is provided with an air outlet part communicated with the engine cabin through an oil cooler cooling air duct. By adopting the arrangement, warm air can enter the engine cabin without improving or disassembling the skin of the engine cabin, so that the time required for disassembling parts such as the skin is shortened, and the problem of increased accident risk rate of the unmanned aerial vehicle caused by disassembling the parts such as the skin is also reduced.
In order to further improve the starting timeliness of the unmanned aerial vehicle engine, the return air pipeline is provided with a return air part communicated with the engine cabin through a gap between the skin of the engine cabin and the propeller. By adopting the arrangement, the air in the engine compartment can flow back to the air heating equipment without improving or dismantling the skin of the engine compartment, so that the time required for dismantling parts such as the skin is shortened, and the problem of increased accident risk rate of the unmanned aerial vehicle caused by dismantling the parts such as the skin is also reduced.
Further, the air heating device comprises a cuboid-shaped shell, the air heating device is located inside the shell, an air outlet connected with an air outlet pipeline is formed in the shell, and an air return port connected with an air return pipeline is formed in the shell. By adopting the arrangement, all parts of the auxiliary equipment can be integrated on the shell to form a set of integrated equipment which can independently operate, thereby being convenient to use.
Further, the air heating heater is a fuel oil type air heater, and an exhaust port of the air heating heater is positioned at the side part of the shell. By adopting the arrangement, the heating efficiency can be ensured, and the influence of heat on other settings beside the unmanned aerial vehicle during heating can be avoided.
