AI Technical Summary

Technical Problem

Existing water rescue equipment has low propulsion efficiency at high speeds, is easily affected by water flow conditions and speed, has slow steering and thrust adjustment, and is prone to capsizing, which affects rescue efficiency.

Method used

The modular pump-jet propulsion system includes a housing, motor, shaft, impeller, shroud, guide vanes, and electronic speed controller. It utilizes eddy currents to generate propulsion, and the electronic speed controller changes the motor speed to achieve rapid steering and thrust adjustment. Multiple propulsion units are installed at the stern of the life-saving equipment to ensure normal propulsion.

Benefits of technology

It improves the high-speed propulsion efficiency of the lifesaving equipment, reduces the impact on water flow and navigation speed, enables rapid turning and thrust adjustment, ensures that the equipment can still be used normally when it capsizes, adapts to changing working conditions, and improves the equipment's maneuverability and reliability.

Abstract

The utility model belongs to life-saving equipment technical field, specifically disclose a kind of modularization pump spray propeller and lifesaving equipment.The utility model's modularization pump spray propeller, impeller of propeller operates in the uniform flow field in fairing, can effectively utilize inflow ram, so that it can better improve anti-cavitation performance at high speed, reach higher propelling efficiency, and not susceptible to water flow condition and sailing speed influence;The motor speed of propeller is changed by electronic speed regulator, to change the water velocity of fairing water outlet jet, and then the propelling force of propeller can be quickly changed;The motor speed of lifesaving equipment two sides propeller is changed by electronic speed regulator, to change the water velocity of two sides fairing water outlet jet and produce speed difference, that is, the quick steering of lifesaving equipment can be realized;Even if lifesaving equipment overturns, because the upper end and lower end of lifesaving equipment stern are all provided with propeller, the normal propelling use of lifesaving equipment is not affected.
