Embodiment

[0036] Example: such as figure 1 with figure 2 As shown, a water spraying device installed on a helicopter includes a high-pressure pump 1 arranged at the bottom of the helicopter (not shown in the figure) and a water gun 2 communicated with the high-pressure pump 1. The water gun 2 includes a gun barrel 3 and The nozzle 4, the gun barrel 3 and the nozzle 4 are welded into an integral structure, one end of the gun barrel 3 communicates with the high-pressure pump 1, and the nozzle 4 is arranged on the other end of the gun barrel 3; the gun barrel 3 is a multi-stage variable-diameter guide tube , that is, along the axial direction of the gun barrel 3, from one end of the gun barrel 3 to the direction of the nozzle 4, the diameter of the inner tube of the multi-stage variable diameter guide tube gradually becomes smaller. The jetted water column in the existing helicopter firefighting can not reach the effect of high water pressure and long range, and during the helicopter fir...

Abstract

The invention discloses a water spraying device mounted on helicopter and a control method. The water spraying device comprises a high-pressure pump and a water gun, wherein the high-pressure pump isarranged on the bottom of the helicopter, the water gun is communicated with the high-pressure pump, the water gun comprises a gun pipe and a nozzle, one end of the gun pipe is communicated with the high-pressure pump, and the nozzle is arranged at the other end of the gun pipe; the gun pipe is a multi-stage reducer flow guide pipe, that is, the diameter of the inner pipe body of the multi-stage reducer flow guide pipe is gradually reduced from one end of the gun pipe to the nozzle in the axial direction of the gun pipe. The water spraying device has the advantages of high water pressure and far range, and high-rise fire fighting requirements are met.

Description

technical field [0001] The invention relates to a water spray device installed on a helicopter and a control method, belonging to the technical field of fire fighting aviation. Background technique [0002] The core equipment of fire-fighting aviation technology is fire-fighting aircraft. Because helicopters have unique properties such as vertical take-off and landing and hovering in the air, they are more suitable for fire-fighting tasks in many aspects. Therefore, fire-fighting agencies in various countries tend to focus on the development of helicopter technology for forest fires. Special tasks such as rescue in water disasters, delivery of combatants, transportation of the wounded, and transfer of trapped persons in (super) high-rise fires are mainly divided into four rescue functions: high-altitude fire extinguishing, emergency rescue, air transportation, and reconnaissance command. [0003] With the rapid development of modern urban construction, there are more and mor...
