The invention discloses a submersible pump and a drainage emergency vehicle. The submersible pump comprises a pump body and a cutting assembly. The pump body comprises a water inlet section, a middle section and a water outlet section which are sequentially arranged in the axial direction. The cutting assembly comprises a fixed knife holder and a movable cutter. The fixed knife holder is fixedly connected to the water inlet section and comprises at least two fixed knife blades arranged in the circumferential direction at intervals. The movable cutter is arranged on the axial inner side of the fixed knife holder and is rotatably arranged relative to the pump body. According to the technical scheme, the cutting assembly comprises the fixed knife holder and the movable cutter, the fixed knife blades are fixed, the rotary movable cutter is arranged, in this way, on the flowing area of the whole pump body, the number of cutters for strip-shaped objects is increased, the cutting efficiency is improved, and then the strip-shaped objects are effectively prevented from winding the impeller.

    本申请公开了一种潜水泵和排水抢险车。潜水泵包括泵体以及切割组件。其中泵体包括在轴向上依次设置的进水段、中间段和出水段。切割组件包括定刀盘和动刀。定刀盘固定连接在进水段上且包括在周向上间隔设置的至少两个定刀叶片。动刀设置在定刀盘的轴向内侧且相对于泵体可转动地设置。本申请的技术方案的切割组件包括定刀盘和动刀这样既有固定不动的定刀叶片,还有转动的动刀,这样在整个泵体的流动面积上,增加了对带状物体切割刀的数量,提高切割效率,进而有效避免带状物体缠绕叶轮。
