Solar Equipment for Life Saving in Water

Abstract

A solar life-saving equipment in the water, which includes a conventional life-saving floatable equipment body. A solar cell, an energy storage device, a switch and a signal generator are integrated in the floatation body. The solar cell is located on the floatation body at a location which is easy to receive sunlight radiation and the switch is situated in a location easy for the user's hand to reach. The solar cell, the energy storage device, the switch and the signal generator are electrically connected to each other to form a complete electric circuit.

Description

FIELD OF THE INVENTION[0001]The invention relates to equipment used for lifesaving in an aquatic environment.BACKGROUND OF THE INVENTION[0002]When a person falls into water accidentally, conventional lifesaving devices such as life jacket, life buoy and life raft can only function to lift the body, while failing to provide generation of emergent help signals. Thus, in dangerous case, the person in distress has to help himself. This no longer satisfies modern day aquatic lifesaving needs.SUMMARY OF THE INVENTION[0003]One object of the invention is to provide convenient solar lifesaving equipment in water.[0004]This object is achieved by the following technical scheme. The solar lifesaving equipment in water comprises a conventional floatation equipment body which includes a solar cell, a storage battery, a switch and a help-requesting signal generator. The solar cell is provided on the floatation equipment body where the solar cell is disposed in a way to facilitate receiving sunligh...

AI Technical Summary

Benefits of technology

[0005]The floatation equipment body of the invention may be a life jacket, life buoy and life raft, while the storage battery may utilize electrolytic capacitor or rechargeable battery. The solar cell is mounted on the floatation equipment body in such a manner that it is readily exposed to sunlight. The solar cell serves to charge the storage battery. The switch is located at a place which allows easy access and operation by the user. Once the switch is turned on, the storage battery device powers the help-requesting signal generator via electric wiring, thereby enabling the generator to generate help-requesting signals. The help-requesting signal generator is able to generate various signals such as voice for help, light of various colors, or specific radio wave, sound wave, light wave according to desired design requirements, thereby facilitating the notification that an emergency is progress being received by the lifesaving personnel. At normal time, the solar cell is positioned on a location where it can receive sunlight radiation with ease so as to store energy, while upon an emergent situation the switch can be turned on so that the signal generator can work regardless whether it is during the day or in the night. The solar cell can be continuously charged until the person in distress is saved.

[0008](2) When an electrolytic capacitor is used in the place of a rechargeable battery, installation is one-time procedure, with high sealability and long service life and avoiding any repairment and replacement of the battery.

[0009](3) The help-request signal generator can be designed to transmit various types of help-requesting signals, for example light wave, sound wave, radio wave or the like, depending upon desired requirement, hence facilitating lifesaving personnel's efforts in locating the people in distress and commencing life-saving operations as soon as possible.

Problems solved by technology

When a person falls into water accidentally, conventional lifesaving devices such as life jacket, life buoy and life raft can only function to lift the body, while failing to provide generation of emergent help signals.

Thus, in dangerous case, the person in distress has to help himself.

This no longer satisfies modern day aquatic lifesaving needs.
