An umbrella-shaped protection device used in an engine air inlet channel comprises an umbrella stand structure, umbrella cloth installed on the umbrella stand structure and an elastic compensation ring installed on the umbrella stand structure and located on the periphery of the umbrella cloth. The umbrella stand structure comprises a sleeve telescopic rod, a supporting seat, a combined sliding seat, a plurality of transverse supporting rods, a plurality of inclined supporting rods and a loosening pin, the sleeve telescopic rod is sleeved with the combined sliding seat in a sliding mode, and a buckling mechanism is arranged in the combined sliding seat. The loosening pin penetrates through the supporting seat, extends into the sleeve telescopic rod and is matched with the buckling mechanism, so that the umbrella stand structure can be unfolded or folded. When the umbrella-shaped protection device used in the engine air inlet channel is used, a worker controls the umbrella stand structure to be unfolded or folded from the top of the umbrella stand structure, operation from the interior of an engine is not needed, protection of the internal structure of the engine is better facilitated, the unfolded umbrella stand structure is better attached to the inner wall of the engine air inlet channel, and the service life of the engine air inlet channel is prolonged. Foreign matters can be effectively prevented from entering the engine.

    一种发动机进气道内用的伞状保护装置,包括一伞架结构、安装在伞架结构上的伞布及安装在伞架结构上且位于伞布外围的弹性补偿环;所述伞架结构包括一套筒伸缩杆、一支撑座、一组合滑座、若干横向支撑杆、若干斜向支撑杆及一松脱销,所述组合滑座滑动套设在套筒伸缩杆上,且组合滑座内置有一扣合机构,所述松脱销穿过所述支撑座并伸入所述套筒伸缩杆内并与所述扣合机构配合,使得所述伞架结构可张开或收合。本案的发动机进气道内用的伞状保护装置使用时,工作人员从伞架结构的顶部控制伞架结构的撑开或收起,无需从发动机内部操作,更利于对发动机内部结构的保护,且撑开后的伞架结构更贴合发动机进气道的内壁,可有效防止异物进入发动机。
