The present invention relates to a driving part and impeller part integrated type waterjet electric propulsion device and a lifesaving jet board comprising the same. The present invention comprises: a device housing fixated on an intake flow passage of a jet board body through a body fixing unit; a rotor housing fixated to the body fixing unit and protecting a rotor spaced from an inner diameter of the device housing; a motor housing fixated to one cross-sectional surface of the rotor housing and having a driving motor therein and power-connected with the rotor; a seal housing fixated to the other cross-sectional surface of the rotor housing and rotating and supporting a driving shaft integrated with the rotor; and an impeller fixated to an end part of the driving shaft. According to the present invention, a driving part and the impeller part are integrated in order to prevent a power loss and reduce vibration and a noise, and the present invention is capable of excluding a winding effect due to foreign substances when water is introduced to the device since a shafting is not exposed.

    본 발명은 구동부 추진부 일체형 워터젯 전기 추진장치 및 이 장치를 탑재한 인명구조용 제트보드에 관한 것으로, 선체고정부를 통해 제트보드 선체의 인테이크 유로상에 고정된 장치하우징; 상기 선체고정부에 고정되고, 상기 장치하우징의 내경과 간격을 두고 설치된 회전자를 보호하는 회전자하우징; 상기 회전자하우징의 일단면에 고정되고, 구동모터가 내장되며, 회전자와 동력연결된 모터하우징; 상기 회전자하우징의 타단면에 고정되고, 상기 회전자와 일체를 이룬 구동축을 회전지지하는 씰하우징; 상기 구동축의 단부에 고정된 임펠러;를 포함하는 것을 특징으로 하는 구동부 추진부 일체형 워터젯 전기 추진장치를 제공한다. 본 발명에 따르면, 구동부와 추진부가 일체화 됨으로써 동력손실을 막고, 진동 및 소음도 줄일 수 있고, 축계가 노출되지 않으므로 물 흡입시 이물질에 의한 감김현상도 배제할 수 있다.
