(Points of interest)
Portable so-called portable generators have been mainly used to convert heat energy and light energy obtained from gasoline engines, cassette cylinders, LP gas, and solar panels into electric power. The number of users who refrain from using the solar panel is increasing, especially when it is used for camping or outdoor leisure, because the exhaust gas may cause adverse effects on the natural environment. The generators used are expensive and large when they require a large amount of power, which increases the weight of the power generator and makes it unstable due to weather such as cloudy weather. As a result, the power generation amount is greatly affected by this.

(Conventional technology)
Reflecting this situation, proposals that can be used to overcome this situation are not unheard of.
For example, as represented by the following proposed in Patent Document 1 (1), a water turbine is attached to a downward rotating shaft inclined in the downstream direction of the water flow provided in the float, and a mooring line is attached to the float , Flowing from the bridge or river bank toward the center of the flow, and the generator is driven by the rotating shaft at the upper part of the rotating shaft, or as seen in Patent Document 1 (2) below, When a plurality of movable blades having a concave receiving surface and a convex back surface are pivotally mounted around the periphery and the rotating shaft is immersed in a posture perpendicular to the water flow, When a water flow is received on the receiving surface, it automatically stands up due to water pressure, and when a water flow is received on the back of each movable wing, it can be self-cleaned while closing so that it automatically collapses due to the water pressure, and the kinetic energy of the water flow is reduced. Can be converted to the rotational force of the rotating shaft In addition, as described in Patent Documents 1 (3) to 1 (6), it is fixedly installed such as the riverbed or the seabed, and the kinetic energy such as river water current, seawater current, or wave motion is applied to the axial rotation force. There are some things that can be converted to.

However, what is installed in the river flow of the float as shown in the former patent document 1 (1) needs to be installed in a river with a certain depth of water and becomes shallow due to drought. In such a case, it may become unusable, and there is a concern that it may be dangerous to install it in a river that is flooding. There is a risk of causing a failure or damage, and the complexity of the structure may cause a deterioration in the stability and durability of the operation. In addition, the latter patent documents 1 (3) to 1 ( 6) Fixed installations such as riverbeds and seabeds as shown in 6) need to be installed with sufficient strength so that they do not easily collapse due to increased water or high waves, and are therefore difficult to remove easily. And personally environment even less that can be installed, were those is difficult to use as a portable power generator.

(Points of interest)
Portable so-called portable generators have been mainly used to convert heat energy and light energy obtained from gasoline engines, cassette cylinders, LP gas, and solar panels into electric power. The number of users who refrain from using the solar panel is increasing, especially when it is used for camping or outdoor leisure, because the exhaust gas may cause adverse effects on the natural environment. The generators used are expensive and large when they require a large amount of power, which increases the weight of the power generator and makes it unstable due to weather such as cloudy weather. As a result, the power generation amount is greatly affected by this.

(Conventional technology)
Reflecting this situation, proposals that can be used to overcome this situation are not unheard of.
For example, as represented by the following proposed in Patent Document 1 (1), a water turbine is attached to a downward rotating shaft inclined in the downstream direction of the water flow provided in the float, and a mooring line is attached to the float , Flowing from the bridge or river bank toward the center of the flow, and the generator is driven by the rotating shaft at the upper part of the rotating shaft, or as seen in Patent Document 1 (2) below, When a plurality of movable blades having a concave receiving surface and a convex back surface are pivotally mounted around the periphery and the rotating shaft is immersed in a posture perpendicular to the water flow, When a water flow is received on the receiving surface, it automatically stands up due to water pressure, and when a water flow is received on the back of each movable wing, it can be self-cleaned while closing so that it automatically collapses due to the water pressure, and the kinetic energy of the water flow is reduced. Can be converted to the rotational force of the rotating shaft In addition, as described in Patent Documents 1 (3) to 1 (6), it is fixedly installed such as the riverbed or the seabed, and the kinetic energy such as river water current, seawater current, or wave motion is applied to the axial rotation force. There are some things that can be converted to.

However, what is installed in the river flow of the float as shown in the former patent document 1 (1) needs to be installed in a river with a certain depth of water and becomes shallow due to drought. In such a case, it may become unusable, and there is a concern that it may be dangerous to install it in a river that is flooding. There is a risk of causing a failure or damage, and the complexity of the structure may cause a deterioration in the stability and durability of the operation. In addition, the latter patent documents 1 (3) to 1 ( 6) Fixed installations such as riverbeds and seabeds as shown in 6) need to be installed with sufficient strength so that they do not easily collapse due to increased water or high waves, and are therefore difficult to remove easily. And personally environment even less that can be installed, were those is difficult to use as a portable power generator.

(Awareness of problems)
As described above, the various water turbines that have been proposed in the past and the hydroelectric piezoelectric machines that use them are difficult to use depending on the depth of the river or sea, the weather, etc., and may be dangerous to install and use. In addition, things that are fixedly installed on the bottom of a river or sea must be installed in a river or sea area with sufficient water volume, and can be easily installed when individuals want to use it. The water flow that is not easily removed after use, but is suitable for installation, management, and use mainly by the national government, local organizations, and companies. It is possible to efficiently convert and use the potential energy of a nearby water stream, such as domestic wastewater from a house drain or rainwater discharged from a rain gutter, to other useful energy.

As described above, the water turbine device of the present invention and the small-scale generator using the water turbine device can achieve the intended purpose evenly by the new configuration, and are easy to manufacture, and have a conventional fuel. Compared to portable generator technology that requires a large amount of energy, it does not require any fuel and enables energy conversion, utilization and power generation more efficiently without adversely affecting the natural environment. The structure is simple, the durability is greatly increased, the weight is low, the cost is low, and the cost is much more economical. In addition, workability such as transportation, installation, use, removal and storage is possible. In the past, it was difficult to install and use, and the safety and stability of the use of river water and seawater was questioned. It is highly appreciated and widely used by households in the generator manufacturing and sales industry that wants to promote the sale of portable generators, and in the power generation industry that constructs, manages, and operates large- and medium-sized power generation facilities. It is expected to become popular.
