The invention relates to a sand blind suppression device system for a helicopter. The device consists of a water tank, a pipeline, a booster pump, a spray head, a fixed pipe and a sealing ring. The device not only can realize a dust falling effect when the helicopter takes off, but also can realize spraying at a fixed angle. According to the device, water in the water tank is sprayed out of the spray head in an atomized mode through centrifugal force generated when the blades rotate, the internal and external pressure difference of the spray head and pressurization of the booster pump, the sprayed water mist is combined with dust and particles in air and settles, and the dust removal effect is achieved; furthermore, a fixed pipe and a sealing ring control device are used for realizing fixed-angle spraying, so that the aim of saving water is fulfilled. The problem that the vision of a driver is limited when the helicopter takes off in a dusty environment can be solved, so that the helicopter takes off more safely.
本发明是一种直升机沙盲抑制装置系统,该装置由水箱,管道,增压泵,喷头,固定管,密封圈组成。本发明不仅可以实现直升机起飞时降尘的作用,进一步还能实现控制固定角度喷洒。装置通过桨叶旋转时的离心力,喷头内外压差以及增压泵增压,将水箱中的水以雾化形式从喷头喷出,喷出的水雾与空气中的灰尘,颗粒结合并沉降,达到除尘的效果;进一步利用固定管与密封圈控制装置实现固定角度喷洒,从而达到节水目的。本发明能克服直升机在多尘环境下起飞驾驶员视野受限的问题而使直升机起飞更安全。
