Embodiment Construction
[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0022] The invention provides an unmanned aerial vehicle for surveying and mapping. By improving the structure of the air filter of the unmanned aerial vehicle, the unmanned aerial vehicle can work normally in a harsh environment at high altitude.
[0023] The drone of the present invention comprises a fuselage, an engine is installed at the front end of the fuselage, a carburetor is connected to the engine, an air filter is connected to the carburetor, figure 1 A schematic diagram showing the connection of the engine, carburetor and air filter in the drone of the present invention. Such as figure 1 As shown, on the exhaust pipe 10 of the engine 1, a first air guide pipe 18 is externally connected, and the first air guide pipe 18 penetrates from the lower end of the air filter 17 and then is formed by the air filter 17. The upper end pierces ...

The invention discloses an extended-range unmanned aerial vehicle with a novel air cleaner. The unmanned aerial vehicle comprises a fuselage, an engine is installed at the front end of the fuselage, a carburetor is connected to the engine, and the air cleaner is connected to the carburetor; a first gas guide pipe is externally connected to an exhaust pipe of the engine, penetrates in from the lower end of the air cleaner and penetrates out from the upper end of the air cleaner. According to the unmanned aerial vehicle, the air cleaner is connected to the carburetor, the gas guide pipe externally connected to the exhaust pipe of the engine penetrates through the air cleaner, air in the air cleaner is heated by heat generated by tail gas of the engine through the gas guide pipe, and therefore air entering the carburetor is hot, a gas inlet is effectively prevented from freezing, and safe and stable operation of the engine is guaranteed; besides, flight performance is improved, and the maximum range of the unmanned aerial vehicle is increased.
Description
technical field [0001] The invention relates to the field of small unmanned aerial vehicles, in particular to an extended-range unmanned aerial vehicle with a novel air filter. Background technique [0002] The engines used by drones on the market are mainly developed for large-scale model aircraft, which have certain limitations, such as poor adaptability to conditions such as temperature, humidity, and air pressure. Ordinary engines cannot run stably at this altitude. Because the air is thin and the temperature is low in high altitude areas, the air intake of the engine carburetor is easy to freeze in this environment, which may reduce the engine speed at least, or cause the engine to stall, seriously affecting the normal operation of the drone. Contents of the invention [0003] To this end, the present invention provides a new extended-range unmanned aerial vehicle with a new type of air filter that can at least solve at least part of the above-mentioned problems, and...
