A low-temperature ignition guarantee device for a small gasoline engine of an unmanned aerial vehicle

Abstract

The invention relates to the technical field of small gasoline engines of unmanned aerial vehicles, and discloses a low-temperature ignition guarantee device of a small gasoline engine of an unmannedaerial vehicle. The device comprises an engine main body, an intake pipe and an exhaust pipe; an intake port of the intake pipe is fixedly connected with a first flange; the first flange is fixedly connected with a second flange through multiple bolts; the end, far from the first flange, of the second flange fixedly communicates with a heating mechanism; the end, far from the second flange, of theheating mechanism fixedly communicates with a guide pipe; a filter mechanism is in threaded connection to the external of an intake port of the guide pipe; a starting mechanism is fixedly connected into the guide pipe; a normally closed valve fixedly communicates to the pipe wall of the guide pipe; an intake port of the normally closed valve fixedly communicates with a thread ring; and the innerwall of the thread ring is in threaded connection with an oxygen bottle. The low-temperature ignition guarantee device of the small gasoline engine of the unmanned aerial vehicle has the advantages ofstable flight of the unmanned aerial vehicle under environments of subzero low temperature and high-altitude oxygen deficiency and high heat dissipating efficiency of the engine of the unmanned aerial vehicle.

Description

technical field [0001] The invention relates to the technical field of small gasoline engines for unmanned aerial vehicles, in particular to a low-temperature ignition guarantee device for small gasoline engines for unmanned aerial vehicles. Background technique [0002] Unmanned aircraft, referred to as "unmanned aerial vehicle", is an unmanned aircraft controlled by radio remote control equipment and self-contained program control device, or is completely or intermittently operated autonomously by the on-board computer. Compared with manned aircraft, Drones tend to be better suited for missions that are too "dull, dirty or dangerous". According to the application field, drones can be divided into military and civilian. For military use, drones are divided into reconnaissance aircraft and target drones. For civilian use, drones + industry applications are the real needs of drones; currently in aerial photography, Applications in agriculture, plant protection, miniature sel...
