Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for generating electricity using a fluid.

[0002]

2. Description of the Related Art Conventionally, as means for transmitting energy, that is, power, there is a belt drive or a gear drive.
These can visually recognize the transmission of power.

[0003] Electric power is widely used as a power source for factory equipment and home electric appliances, and these electric powers are used in hydroelectric power stations, thermal power stations, or nuclear power stations, except for factories having private power generation facilities. Power is being transmitted from This transmission line requires installation and laying by qualified personnel.

[0004]

Along with the increase in power demand in the [0006] In recent years, the expansion of power generation equipment has become an urgent need,
Hydropower plants have a problem of destruction of the natural environment, thermal power plants have a problem of depletion of petroleum resources, environmental pollution or global warming due to carbon dioxide emissions, and nuclear power plants have measures against radioactivity and alleviation of local residents' anxiety. to become a problem, it is the actual situation that can not be promoted easily power plant construction.

On the other hand, power generation facilities utilizing natural energy such as solar power and wind power have been constructed.
Since the amount of power generated varies greatly depending on the weather and seasons, it cannot be a stable power source.

Various power generators have been developed in addition to the above, but there are many which require enormous capital investment and those which are theoretically possible but extremely difficult to put into practical use. No alternative to power generation has emerged.

An object of the present invention is to provide a power generator having a relatively simple structure and easy installation.

[0008]

According to the present invention, there is provided a tubular body which is formed into an annular shape by enclosing a fluid therein, a power source provided inside the tubular body for transmitting power to the fluid, And means for generating electric power by the power transmitted by the motor.

[0009] By such a configuration, the fluid given speed by the power source is going to transmit the power to the means for generating electric power. Thereby, electric power for operating each electric device can be taken out by the energy generated by the power generation device provided near the supply position.

[0010] The tube in which the fluid is enclosed forms an annular shape, so that the fluid initially given a speed efficiently transmits power to circulate.

In the present invention, an embodiment in which the fluid is a gas, the power source is a fan, and the power generation means uses a wind power generator is possible. In this embodiment, the fluid for transmitting power is air. At this time, a duct can be used as the tubular body, and a propeller (fan) can be used as the power source. Further, a generator (wind power generator) having a propeller can be used as a means for generating power. Thereby, power can be transmitted by arranging the duct on a target path.

Further, an embodiment is possible in which the fluid is a liquid, the power source is a screw, and the power generation means uses a hydraulic power generator. In the embodiment using water as the transmitting fluid, a tube is adopted as the tubular body, the power source is constituted by a motor and a screw having a waterproof function, and the power generating means is also a generator and a screw having a waterproof function. With this configuration, power can be transmitted by disposing the tube in a target path.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a partially cutaway perspective view showing a power generator according to an embodiment of the present invention, and FIG. 2 is a perspective view showing another embodiment of the present invention.

The power generator 1 according to the present invention comprises a duct 10 which is an annular tube, a motor 12 installed inside the duct, to which a power supply 11 is connected, and a power source 14 constituted by a fan 13 connected to an output shaft of the motor 12. And the power source 14
A propeller 15 and a propeller 1 arranged to rotate by a flow 18 of air within a more accelerated duct.
5 is constituted by a power generating means 17 constituted by a DC generator 16 connected to the DC power generator 5.

A fan 13 rotated by a motor 12
Is generated by the air flow 18 inside the duct 10.
7 is rotated, and a DC generator 16 connected to the propeller 15 generates electric energy. The electric energy generated by this is home appliance 1
9 is used as the energy to operate.

A plurality of the power generating means are arranged in the duct 10 in the same direction.
Are connected by wiring.

Since the duct 10 has an annular shape, the air flow 18 sent from the power source 14
Come back to. As described above, the power generation device of the present embodiment can generate power by effectively utilizing the flow of air generated by the power source.

FIG. 2 shows another embodiment of the present invention. In the present embodiment, a power source 21 and a power generation unit 22 are provided inside a tubular duct 20.

In this embodiment, the fluid is filled in the duct 20 as water. Power source 21 is battery 11
And a screw 24 connected to the output shaft of the submersible motor. Further, the power generating means 22 is also provided with a screw 24
Is provided with a generator 25 which is connected to a shaft and has a waterproof mechanism, and is installed inside the duct 20. Power source 2
The water speeded by one screw 24 forms a unidirectional water flow 26 inside the duct 20. This stream 2
6, the screw 24 of the power generation means 22 inside the waterway 20
Is rotated to rotate the input shaft of the generator 25 to generate power. The water flow 26 also circulates because the duct 20 has a closed water channel and returns to the power source 22 again, so that the energy of the water flow generated from the power source 22 is efficiently used.

The duct 20 can be installed in any direction. By making the material of the duct 20 transparent, the flow of the fluid inside the duct can be visually recognized by the rotation of the screw 24.

According to the present invention, the following effects can be obtained. (1) a tubular body that is formed into an annular shape by enclosing a fluid therein;
By providing a power source provided inside the tubular body for transmitting power to the fluid, and a means for generating power by the power transmitted by the fluid, the fluid generated by the power source is supplied to each power generation unit. By transmitting power, electric energy can be extracted from each power generation unit. (2) Since the tube in which the fluid is sealed forms an annular shape, the fluid once given a speed by the power source circulates through the inside of the tube, so that power can be efficiently generated. (3) The power generation device can transmit power to each device by installing a tube and a power generation means near a device such as a home appliance to be used and connecting to a power source.
