Magnetic floating self-powered radio transmitter

The present invention relates to a radio transmitter for self-generating magnetic power, and particularly to a radio transmitter that generates power to be supplied to a power source by a relative movement of a first magnet between a second magnet and a third magnet to generate a change in magnetic flux density.

In order to study wild animals, wildlife researchers will install radio transmitters on their bodies to track their daily life habits.

The general radio transmitter is, for example, the Republic of China Invention Patent Bulletin No. I296333 "Micro Tracking Device for Tracking the Motion Track of Animals and Its Usage Method", or the Republic of China New Patent Bulletin No. M370296 "Bird Tracking Device, Base" Taiwan and its bird tracking system, however, all of the above disclosed cases need to use the battery to provide the overall device power, resulting in the following defects:

1. Use the built-in battery to supply the power source, and replace or charge it for a while.

2. It is not easy to replace the battery if it is installed on a bird or a ferocious animal.

3. If the battery is dead or faulty, the object to be tracked will lose its signal and lose its connection.

Accordingly, it is a primary object of the present invention to provide a radio transmitter having a self-generating function, particularly a radio transmitter that generates an induced current by varying the magnetic flux density.

Based on the above objectives, the inventors have developed a magnetic floating self-powered radio transmitter, including one hair, in the spirit of continuous innovation and research and development. An electric unit and a radio transceiver unit, the power generating unit has a tube body, a first magnet is disposed in the tube body, and a second magnet and a third magnet are respectively connected to the two ends of the tube body, and the first The N pole of the magnet faces the N pole of the second magnet, the S pole of the first magnet faces the S pole of the third magnet, and the power generating coil is wound around the tube body, by the first magnet Generating a magnetic force of the same polarity with the second magnet and the third magnet, respectively, causing the first magnet to reciprocate in the tube body, thereby generating a change in magnetic flux density, causing the power generating coil to generate an induced current, and conducting the current Radio transceiver unit.

Further, the power generating unit has a charging battery electrically connected to the power generating coil, and the charging battery is electrically connected to the transceiver unit for storing excess power.

Further, a sleeve is disposed on the tube body and the power generating coil, and a first fixing portion is respectively disposed on the two ends of the tube body, and the second magnet and the third magnet are respectively fixed on a cover body.

Placed in the chamber whereby the sleeve and cover protect the internal components from damage.

Further, a coupling member is disposed on the sleeve to be combined with the object to be tracked, especially for the researcher to combine it with the wild animal to be tracked.

The main effects of the present invention are:

1. The direction of placement is not limited.

2. The slight action can make the first magnet start reciprocating motion. At the same time, the first magnet can continue to move inside the tube to ensure sustainable production of electricity.

3. In addition to directly transmitting power to the transceiver unit, it can also be stored to the rechargeable battery so that the transceiver unit does not have the concern of power failure.

4. This creation is particularly suitable for tracking and positioning of wild animals such as birds, land animals or marine life.
