Abstract

The water provides a water signal generating device. With the water signal generating device adopted, a power source is not required, and a signal generating unit can be powered through utilizing water mechanical energy. The water signal generating device includes a contact type generator made of a flexible material and a signal generating unit; and a wavy electrode layer and a friction layer of the contact type generator can contact with and leave away from each other under the impact of the mechanical energy of water, and contact charges can be generated at the surfaces of the wavy electrode layer and the friction layer, so that electric signals can be generated between an electrode layer arranged on the friction layer and the wavy electrode layer, wherein the electric signals are adopted as a power source of the signal generating unit so as to drive a signal generating component in the signal generating unit to emit light signals or wireless signals. According to the underwater signal generating device, a static electricity friction generator can be integrated on the contact type generator, so that the static electricity friction energy of a liquid-solid interface and the mechanical energy of water wave slapping can be utilized at the same time. The signal generating device can be integrated on a lifesaving device such as a life jacket, so that a body floating on water can automatically send out distress signals.

Description

technical field [0001] The invention relates to an underwater signal generating device, in particular to a self-powered underwater signal generating device which converts mechanical energy in the form of waves, running water, raindrops, etc. into electric energy and a lifesaving device using the signal generating device. Background technique [0002] When an object is floating in water, especially in a large area of ​​water, the position of the object is usually confirmed by the color of the floating object, the colored pigment carried, etc. This method requires a lot of manpower and material resources to search. With the development of electronic equipment technology, electronic devices can also be installed on the floating objects, and the floating objects can be remotely tracked and positioned through the signals sent by the electronic devices. [0003] However, this method of arranging the electronic device on the floating object needs to provide power for the electronic...
