The invention is related to a life-saving device for propelling a buoy ring in the water. More particularly, the life-saving device is able to transport a floating object, such as a buoy ring or a foam noodle, rapidly over the surface of water to a drowning person who is waiting for helps. The advantages of the invention are to increase the efficiency of a rescue mission and to reduce the risks a rescuer or a lifeguard encountered.
When a drowning person in the water is calling for helps, the most important task for a lifeguard or a rescuer is to deliver a buoy ring or an object with buoyancy rapidly to the drowning person to grip and clamber about, and then to tow the drowning person out of the water as quickly as possible.
In general, a lifeguard will either swim, carrying a floating object, or throw out a buoy ring toward a drowning person. However, it consumes a lot of physical strength for the lifeguard to swim with a floating object against water resistance. In addition, it causes huge risks for the lifeguard to deal with the drowning person, such as to release grip and to free clutch of the drowning person. As to throwing out a buoy ring, there are limitations of accuracy in both the direction and the distance depending on different lifeguards and the circumstances of the rescue scene.
Accordingly, the abovementioned prior arts of rescuing a drowning person are rather unsafe, inconvenient and inefficient with many shortcomings to be improved.
The primary object of the invention is to provide a water propelling device for a life-saving buoy ring. The presented device can be fastened to various types of objects with buoyancy such as a standard buoy ring, a swim board or a foam noodle. Therefore, the floating object is able to be transported rapidly over the surface of water toward a drowning person who is waiting for helps by the invented water propelling device. The invention thereby is able to increase efficiency of the rescue mission and to prevent a lifeguard or a rescuer from encountering risks.
In order to achieve the abovementioned object, the invention discloses a water propelling device for a life-saving buoy ring which comprises three mechanical parts, an adjustable clamp apparatus, a waterproof chamber and a hydro-driving mechanism. A control monitor with a screen panel, or a mobile phone with control software installed, is used by a rescuer or a lifeguard to operate the water propelling device remotely. Three mechanical parts are connected together tightly to form a rigid structure.
The adjustable clamp apparatus is composed of an adjustable clamp holder, an upper clamp and a lower clamp. The main function of the adjustable clamp apparatus is to fasten firmly an object with buoyance between the upper and the lower clamps. The clearance between the upper and the lower clamps can be changed to suit various types of floating object such as a buoy ring, a swim board or a foam noodle by setting the opening of the adjustable clamp holder.
The waterproof chamber is mounted on the top of the adjustable clamp apparatus to ensure the waterproof chamber being above the surface of water at all times in a rescue mission. Inside the waterproof chamber, there are electronic circuit boards, a power supply unit and batteries, a wireless signal communication module and antennas, various sensor modules and an electronic speed controller wired together to actuate and control movements of the invented water propelling device with the fastened floating object in the water. The command and response signals are exchanged wirelessly between the remote operating rescuer through the control monitor or the mobile phone and the waterproof chamber.
The hydro-driving mechanism is fixed to the bottom of the adjustable clamp apparatus to ensure the hydro-driving mechanism being submerged in the water at all times in a rescue mission. In addition, the hydro-driving mechanism is connected to the electronic speed controller inside the waterproof chamber by electric cables to provide a propeller function, for moving forward and backward, and a rudder function, for turning directions. The propeller function and the rudder function work together harmoniously enabling the invented water propelling device with the fastened floating object to perform movements in the water.
As a result, to rescue a drowning person calling for helps, a rescuer or a lifeguard fastens an object with buoyance available in the rescue scene with the invented water propelling device first, and puts the device and the floating object together in the water. Then, the rescuer is able to deliver the floating object to the drowning person by operating the control monitor or the mobile phone which wirelessly connects with the invented water propelling device. The command signals from the control monitor are received by the wireless signal communication module and antennas, and are transmitted to the electronic boards for processing. The output signals for the propeller function and the rudder function are generated accordingly and sent to the electronic speed controller to actuate the hydro-driving mechanism. In the mean times, various sensor modules inside the waterproof chamber collect surrounding and status information during the rescue mission for the electronic boards to process. The output signals are sent to the electronic speed controller and the hydro-driving mechanism for feedback-control adjustment of movements, and to the wireless communication modules and antennas to transmit back to the control monitor or the mobile phone for the rescuer to supervise.
Therefore, to rescue a drowning person in the water by the invented water propelling device with a life-saving buoy ring is able to resolve the limitations of the distance and the direction of throwing out a buoy ring by different rescuers at different rescue scenes. In addition, the rescuer will be released from the risks of consuming physical strength and encountering resistance against the drowning person to accomplish a rescue mission safely and quickly.
To enable a further understanding of the said objectives and technical methods of the invention herein, the drawings below are followed by the detailed descriptions of the preferred embodiments.

The adjustable clamp apparatus 10 fastened to a floating object 40 of various types, such as a buoy ring, a swimming board or a foam noodle, is fixed to the bottom of the waterproofed chamber 11. The waterproof chamber 11 is equipped with electronic circuit boards 12 connecting with a power supply unit and batteries 15, a wireless signal communication module and antennas 13, status sensors 16, a GPS (Global Positioning System) 17, a camera 18, a spotlight and a flashing light 19, a microphone 110, a speaker 111 as well as an electronic speed controller 14.
The hydro-driving mechanism 20 is fixed to the bottom of the adjustable clamp apparatus 10 to transport the fastened buoy ring 40 over the surface of water. The electronic speed controller 14 is wired with the hydro-driving mechanism 20, receiving signals generated by the electronic circuit boards 12 to actuate and control the rotating speeds of various propellers 21, 22 in the hydro-driving mechanism 20.
The control monitor 30 is used to transmit command signals wirelessly to the wireless signal communication module and antennas 13. The wireless command signals received by the wireless signal communication module and antennas 13 are sent to the control electronic circuit boards 12 for processing. The outputs are then used by the electronic speed controller 14 to actuate the speed and the direction of rotations of the propellers 21, 22 in the hydro-driving mechanism 20. As a result, the invented water propelling device with a fastened life-saving buoy ring 40 is able to perform movements of moving forward and backward and turning left and right in the water according to the operating commands of the rescuer sending by the control monitor 30. Various type of objects with buoyance can be used in a rescue mission by setting the adjustable clamp apparatus 10 of the invented water propelling device, as shown in
When a drowning person is calling for helps, the rescuer can deliver a buoy ring 40 rapidly over the surface of water to the drowning person by operating the control monitor 30 and the invention. Therefore, there will be no limitation of accuracy in the distance and the direction of throwing out a life-saving buoy ring. In addition, the rescuer does not have to swim toward the drowning person with the buoy ring. The risks of consuming physical strength and the dangers caused by the resistance of the drowning person encountered by the rescuer are lessened.
