Abstract

PROBLEM TO BE SOLVED: To drive a generator to generate power by elevating or rotating an input shaft mounted to a floating case, in association with vertical motion and flow of water, and converting elevating motion and rotary motion of the input shaft or the oscillating motion of the floating case into rotary motion of the input shaft having an eccentric weight. SOLUTION: A case 2 formed of plastic or the like is fixed onto a graft A for culturing pearls or the like, and a generator M is provided in the case 2. In association with vertical motion of water, a resistance plate 25 is vertically moved in relation to the case 2, and an input shaft 23 integral with the resistance plate 25 is vertically moved. A rack gear 24 provided at the upper end of the input shaft 23 rotates a pinion gear 21. A driving shaft integral with the gear 21 is rotated to turn a rotor of the generator M. At this time, high- tension electromotive force is generated to generate power. The generated power is transmitted to a light emitter 16 through a lead wire to emit light. The light emitter 16 therefore emits light every vertical motion of the input shaft 23 so as to dispense with a dry battery or the like.

Device, transmitter, position measuring device (G,
P, S) or a method and apparatus for generating electric power to be supplied to a light-emitting device for lighting of a lightly-powered light vehicle on land.

[0002]

2. Description of the Related Art A light emitting device is attached to a raft for aquaculture, a float used for fishing in a line, or a device floating on the water such as a route marker, a receiver, a transmitter, and a device for position measurement. The other boats have made their presence clear, but they use batteries as the power source for these light emitters. Further, a light vehicle such as a wheelbarrow on land is not provided with a light-emitting device or the like.

[0003]

Since the light-emitting devices of the various facilities floating on water as described above need to be lit all night, a power supply box equipped with a large-capacity battery is required. If a dry battery is used as this battery, the replacement work that is extremely troublesome due to its short life is required, and the dry battery that has become unnecessary by replacement is
It was a problem because the ocean was often dumped.

[0004] Therefore, an object of the present invention is to make use of the energy generated from above and below the water surface, and in the case of light vehicles such as bicycles and wheelbarrows on land, to use the rotation of the tires of the wheels to make them extremely small. It is an object of the present invention to provide a method capable of generating electric power by a driving force and a device therefor.

[0005]

In order to solve the above-mentioned problems, the present invention provides a generator in a floating case floating on water, and an input shaft mounted on the floating case so as to be vertically movable or rotatable. It moves up and down or rotates with the rise and fall and flow of water, and the up and down movement and rotation movement of this input shaft or the swinging movement of the floating case is changed to the rotation movement of the input shaft having an eccentric weight, and these rotation movements A configuration in which a generator is driven to generate power, a generator is provided on a light vehicle such as a bicycle or a handcart or a walking stick, and a friction roller provided on a drive shaft of the generator is brought into contact with tires of wheels of the light vehicle. Alternatively, a configuration is employed in which electric power is generated in the generator by utilizing the elevating and lowering of an action rod due to the vertical movement of a walking stick.
