The invention discloses a water jet propeller structure which comprises a guide vane body, an impeller shell and an impeller rotating relative to the guide vane body. The impeller shell is arranged atthe outer side of the impeller in a sleeving mode and fixedly connected with the outer wall of the guide vane body, the impeller comprises an impeller hub and a plurality of impeller blades, and theimpeller blades are fixed to an outer ring of the impeller hub; and the guide vane body comprises a guide vane hub, and a first gap is formed between the impeller hub and the guide vane hub. The waterjet propeller structure is characterized in that an extending object stretching across the first gap between the impeller hub and the guide vane hub is fixed on one of the impeller and the guide vanebody, and a second gap is formed between the other one of the impeller and the guide vane body and the extending object. According to the water jet propeller structure, due to the fact that multiplepositions of the first gap between the impeller and the guide vane body are covered with the extending object, when a propeller operates, net-rope-shaped foreign matters are not prone to being wound into the first gap any more.
本发明公开了一种喷水推进器结构,包括导叶体、叶轮壳体以及相对导叶体转动的叶轮,叶轮壳体套在叶轮的外侧且与导叶体的外壁固定连接,叶轮包括叶轮轮毂和多个叶轮叶片,多个叶轮叶片固定在叶轮轮毂的外圈上,导叶体包括导叶轮毂,叶轮轮毂和导叶轮毂之间设有第一间隙,其特征在于,所述的叶轮和导叶体两者的其中之一上固定有横跨叶轮轮毂和导叶轮毂之间第一间隙的延伸物,另一个与延伸物之间设有第二间隙。本发明提供的喷水推进器结构中,由于叶轮和导叶体的第一间隙有多处被伸出物覆盖,推进器运转时网绳状异物不再容易卷入第一间隙中。
