Tool for reducing head loss of large-diameter sewage pump

The utility model provides a tool for reducing the head loss of a large-caliber sewage pump, and solves the problem that a 90-degree break angle formed by a water hose can cause larger head loss during engineering precipitation construction. The supporting device comprises a supporting shaft which is made of elastic materials and can be bent, the supporting shaft extends in the front-back direction, at least three arc-shaped supporting strips are arranged on the supporting shaft in the direction of the central axis of the supporting shaft, openings of the arc-shaped supporting strips face upwards, and a gap is reserved between every two adjacent arc-shaped supporting strips. The tool is convenient to use, simple in structure, convenient to machine, small in size, light in weight and convenient to carry and transfer. The problems of large water pump loss and low water pumping efficiency caused by 90-degree break angles formed by water belts in deep foundation pit water pumping are effectively solved. 本实用新型提供了一
