Embodiment 1

[0032] The structure of a fire-fighting unmanned aerial vehicle according to the embodiment of the present invention is as follows: Figure 1 to Figure 6 As shown, it includes: drone body 1, main duct assembly 2, tail thrust duct assembly 3, landing gear 4, engine 5 and gearbox 6; main duct assembly 2 is located in the middle of drone body 1 ; Tail thrust duct assembly 3 is located at the tail of drone body 1; landing gear 4 is located at the bottom of drone body 1; engine 5 is located inside drone body 1 and is connected to gearbox 6 through gears, and drives the main duct assembly into 2 and the tail push duct assembly 3 to complete the take-off and landing of the unmanned aerial vehicle and advance.

[0033] Among them, the main duct assembly 2 includes: the main duct 23 of the UAV body, the upper rotor head assembly 24, the lower rotor head assembly 22 and the main duct transmission system 21; the main duct 23 of the UAV body is located in the unmanned In the middle of th...

Embodiment 2

[0040] Such as Figure 4 , 6As shown, when the UAV is provided with a tail thrust duct assembly 3, the tail thrust duct transmission system 34 includes: a coupling 347, a connection plate 348, and a tail thrust drive shaft 349; the connection plate 348 is sleeved on the gearbox 6 on the output shaft; one end of the tail thrust transmission shaft 349 is connected with the connecting plate 348 through a coupling 347; the other end of the tail thrust transmission shaft 349 is connected to the 370 rotor head assembly 31; the 370 rotor is driven by the tail thrust duct transmission system 34 head component;

[0041] Its working process is: after the UAV takes off through the above steps, it drives the 370 rotor head assembly through the tail push duct transmission system 34 to make the UAV advance. The tilt angle makes the 370 rotor head assembly deflect and generate a deflection force to adjust the direction of the drone.

[0042] Among them, the engine 5 of the above two UAVs ...

Abstract

The invention discloses a firefighting unmanned ducted helicopter and relates to the field of firefighting equipment. The firefighting unmanned ducted helicopter comprises an unmanned helicopter body, a main duct assembly, a stern thrust duct assembly, a landing gear, an engine and a gearbox; the main duct assembly is positioned in the middle of the unmanned helicopter body; the stern thrust duct assembly is positioned at the stern of the unmanned helicopter body; the landing gear is positioned at the bottom of the unmanned helicopter body; the engine is positioned within the unmanned helicopter body and connected with the gearbox through a gear; and the engine drives the main duct assembly and the stern thrust duct assembly. The firefighting unmanned ducted helicopter is mainly used for fire rescue and disaster control in various places, carrying rescue equipment, performing dangerous rescue works instead of firemen, rapidly controlling and reducing disastrous situation and saving lives and money of fire victims in time.

Description

technical field [0001] The invention relates to the field of firefighting equipment, in particular to an unmanned helicopter for a firefighting duct. Background technique [0002] With the advancement of urbanization, the speed of high-rise construction is accelerating, but the development of equipment for high-rise fire protection is relatively lagging behind. At the same time, with the rapid development of the chemical industry, all kinds of fire incidents that are easy to explode and are not suitable for human beings to deal with are on the rise. In recent years, the number of casualties of firefighting officers and soldiers has been increasing due to lagging firefighting equipment in high-rise buildings and close-range handling of explosive cases during firefighting. This firefighting problem has not been resolved. At present, aerial ladder fire trucks are mostly used to solve the problem of high-rise fire protection. The effective operating height of ordinary aerial la...
