Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the construction of a structure of a power generator for the purpose of small-scale power generation using the water flow of a river.

[0002]

2. Description of the Related Art In the conventional power generation, the mainstream is a power generation configuration in which a water flow velocity is guided by a rotary shaft through a rotary vane and a generator motor is rotated. The water-drop head power generation dam has a large-scale configuration, and engine-powered portable generators and the like are in widespread use (see, for example, Japanese Patent Publication No. 2-55679 and Hei 2-332869).

[0003]

[Problems to be Solved by the Invention] A power generation device using a water stream as a power generation device that can easily secure power for activities around rivers such as camps.

[0004]

In order to achieve the above-mentioned object, the rotation is generated by the flow velocity of the river water flow based on the inner wall multi-blade hollow tube of the specification of Japanese Patent Application Nos. 1-159621 and 2-4618. Therefore, it is structured to generate electricity.

Therefore, the decrease in power generation due to the insufficient flow velocity
The transmission mechanism is set to maintain the rotation speed of the electromotive component.

[0006]

[Operation] The main body is installed in the water of the river, and the water flow passes through the multi-blade hollow tube, so that a rotating force is generated in the hollow tube. Join to the part.

As a result, the number of rotations required for the power generation capacity can be maintained.

In FIG. 2, the operating structure of the transmission mechanism is constructed by a hydraulic system. It works as a shifting function based on the fluid velocity pressure depending on the volume. The speed change ratio varies depending on the pump diameter and the ratio of the flow speed, the volume, and the number of blades. Stabilization of the rotation speed, like centrifugal clutch technology,
It is configured to stabilize the rotational speed by hydraulic flow control utilizing centrifugal force.

Therefore, the main body is installed in a river having a flow velocity, and electric power is led out by a cable and used. To prevent outflow, maintain a stable position with a tow rope.

The tow rope is provided with tension and has a structure for stopping the generation of electricity when the rope is cut off and leaked.

EXAMPLES Examples will be described with reference to the drawings.
The structure shown in FIG. 1 aligns the covers (1) and (2) having a dustproof net for collecting water flow in the freely rotatable multiblade hollow tube (3) by the support structure from the cover (2). Let
The generated rotational force is made up of gears to form a gear shift component,
This rotation is joined to the rotation of the electromotive structure.

The electromotive component is described in Japanese Patent Application No. 3-184213. Set the power generation capacity at an arbitrary length. The winding coil configuration (5) provides power output from the terminal configuration.

[0013] Rotational power is shut off at the time of outflow / leakage. For example, a structure in which the speed change mechanism is separated by a spring is used. In Fig. 2, the structure is designed to prevent accidents by shutting off the hydraulic line.

Since the main body is always underwater installed, the metal (8) for supporting the rotation of the multi-blade hollow tube (3) is a waterproof metal for maintaining airtightness, and is considered to prevent water leakage into the structure. That.

When a coaxial connection is used in a drainage pipe having a large amount of water, a bypass pipe having a saturated water amount should be set. The diameter of the net matches the diameter of the pipe.

By integrally forming the above as shown in the figure, the permanent magnet of the electromotive component can rotate at high speed, and an electromotive current is generated in the electromotive coil fixed from the cover. Note that the coil and magnet reversal structure of the electromotive component is not preferable due to the effect of centrifugal force on the coil during long-term use.

FIG. 3 shows an example of a configuration using a multiblade hollow tube and an existing power generation motor. In this structure, the rotation of the multi-blade hollow tube is output as a vertical axis output or as a hydraulic line, and is connected to the shaft of the generator motor via a speed change component. Follow the installation specifications for a long time. Displayed in hydraulic specifications. See Fig. 7 of mechanical patent application No. 2-4618.

In this method, since the power generation section can be set above the water surface, waterproofing measures are simple. In case of hydraulic type,
The generator motor can be installed at any point (considering pressure fluctuations) using only the circulating oil line. For the integrated type, set a generator motor in the body frame. The power generation component should be set on the ground that can handle fluctuations in water levels as much as possible.

An example of use is shown in FIG.

EFFECTS OF THE INVENTION The present invention provides the following effects by virtue of the constitution and establishment as described above.

This structure is convenient for outdoor activities in the river basin because it is possible to easily secure electricity even in the water flow velocity and water amount of a small river.

By setting the speed change component, it is possible to rotate the electromotive component at a high speed and maintain a stable rotation speed.

The outflow / leakage prevention function enables safe use.

Although there are various kinds of equipment, this device also corresponds to one item of the energy-saving purpose equipment group.

No running cost is required due to the use of river water flow.

Even in the drainage pipe, the electric power can be secured by the coaxial connection.

It is possible to provide a low-cost electric power securing device even in an undeveloped area.
