The present invention relates to a submerged motor pump. The purpose of the present invention is to provide the submerged motor pump having a structure for protecting a cable and lifting itself and capable of easily performing lifting operation for inspection and maintenance of a submerged motor pump while providing an environment for safely protecting various cables connected to a submerged motor pump from water flow. According to the present invention, the submerged motor pump comprises: an electric motor for generating a rotary force by receiving electricity and rotating a rotary shaft by using the generated rotary force; and an impeller combined with the rotary shaft for allowing a fluid to flow while rotating. Moreover, the submerged motor pump installed inside a tubular case and arranged in water comprises: a protective tube arranged inside the tubular case to accommodate a cable connected to the submerged motor pump inside to transmit an electronic and control signal to the submerged motor pump, wherein an upper end is installed in the upper end part of the tubular case and a lower end is installed in the submerged motor pump to be fixed, and having an extendable structure in a longitudinal direction by being formed as a telescopic structure wherein at least two protective tubes having different diameters are combined with each other to form a multi-stepped structure; and a lifting means arranged inside the protective tube, and for lifting the submerged motor pump to an upper part by including a hydraulic cylinder whose upper end part is fixed to the upper end part of the tubular case, and lower end part is installed to be connected to the submerged motor pump. |
