Water propelling device for a life-saving buoy ring

Abstract

A water propelling device is invented to rescue a drowning person with more efficiency and less risks, which includes an adjustable clamp apparatus, a hydro-driving mechanism, a waterproof chamber and a control monitor. The adjustable clamp apparatus is able to fasten various type of life-saving buoy rings. Inside the waterproof chamber, electronic circuit boards, a power supply unit with batteries, a wireless signal communication module and antennas, various sensor modules and an electronic speed controller are wired together as a control unit. The hydro-driving mechanism is at the bottom of the adjustable clamp apparatus, which is connected with the control unit to actuate and control the movements. Wireless signals are transmitted and received between the control monitor and the control unit, allowing a rescuer to operate the water propelling device remotely to deliver a life-saving buoy ring over the surface of water toward the drowning person.
