Abstract

PROBLEM TO BE SOLVED: To enable the control of turbulence and increase the output, by downsizing a strut pipe, and making a static current plate and a rotary current plate into round plates and also, increasing the number of plates for parallel connection of rotary current plates. SOLUTION: For the device, an elbow is connected to the bottom of a strut pipe having a rotary shaft 1 within, and within the elbow, bevel gears are engaged with each other, thus rotary shafts 1 and 11 are set vertically. Then, the rotary shaft 11 projects out of the elbow 12 through a bearing 5, and a connecting pipe 15 which is provide integrally with plural rotary current plates 2 where scale-type elastic vanes 4 are attached is set onto the rotary shaft 11, and is fixed with a pin 8. Moreover, a static rectifying plate 3 is of such constitution that it is fixed outside to the right opening of the elbow 12 through a stud bolt 14. As a result, it turns out that one piece of static current plate 1 and a plurality of rotary current plates are arranged in parallel, so this is effective for prevention of turbulence of water flow, and also, since the size of the scale-type elastic vanes and the number of vanes can be set freely and the size of the rotary current plates and the number of plates can also be designed freely, the output geared to necessity can be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outboard motor used as a propulsion device attached to the rear of a boat or small boat, and is named as an electric generator. Assuming that the hull is stationary while the ship is sailing when attached to a part of the ship, the water flowing around it can reach several tens of kilometers per hour. The electric power can be taken out by attaching the generator of the water flow to a part of the hull in the same manner as the outboard motor. In addition, the present invention can be used as a device for converting kinetic energy of fluids such as rivers, waterfalls, tidal forces and the like into electric energy, not limited to ships. TECHNICAL FIELD The present invention relates to a method for manufacturing a screen generator.

[0002]

2. Description of the Related Art Conventionally, this type of apparatus has not been developed so much, and a propeller turbine is suitable. However, the flow generated in the natural world has a low streamline and turbulent flow, resulting in poor energy conversion efficiency. There is almost no value as a product.

[0003]

Most of the conventional propeller turbines have the characteristic that the output is small because only a single turbine can not be connected in series or parallel. The present invention can increase the output by connecting in parallel, and aims at controlling the turbulence and increasing the output by installing a stationary rectifying plate (3) and a rotating rectifying plate (2) as a countermeasure against turbulence generated in the natural world.

An object of the present invention is to make it possible to easily connect one stationary current plate (3) and a plurality of rotary current plates (2) with scale-shaped elastic blades in parallel, thereby increasing the output simultaneously with the rectifying action.

[0005]

As a means for achieving the above object, a stationary rectifying plate is provided which is miniaturized to reduce the loss such as the resistance of the device as much as possible and which is mounted as a turbulence prevention measure. (3) and the rotary rectifying plate (2) were configured as circular plates. Further, as a means for increasing the output, the problem can be solved by increasing the number of parallel-connected rotating rectifying plates (2) on which scale-shaped elastic blades (4) are arranged.

[0006] The scouring power generator can be installed not only at the rear of the hull but also at any part of the hull, and can be installed in any manner even in the case of rivers, waterfalls, or tidal currents due to tidal forces.

[0007]

The output of the generator with the above construction can be increased by increasing the number of parallel connection of the rotary rectifying plates of the scale turbine, and the scale turbine (FIG. 2) is connected to the rotary shaft (1). An I-type and a scale turbine (FIG. 2) connected in series (FIG. 4) are provided on a rotating shaft (11), and an L-shape is engaged with the rotating shaft (1) by a bevel gear (FIG. 5). Although the rotation direction of (1) is the same, the rotation directions of the scale turbine are perpendicular to each other in the I type and the L type.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a rotary shaft (1), a rotary rectifying plate (2), a scale-shaped elastic blade ( It is a perspective view which shows the structure of 4). FIG. 2 is a plan view thereof.
In FIG. 1, no rotational force is generated for the flow of water in the direction of the rotating shaft (1), but a rotational force is generated for the flow of water in the radial direction of the rotating shaft (1). The reason is that the flow is rectified above and below the rotary rectifier plate (2) and passes through the scale-shaped elastic blades (4) implanted on both upper and lower surfaces of the rotary rectifier plate. At this time, the flow from the fixing surface, that is, from the fixing hole (6) side, is such that the tip of the scale-shaped elastic blade is a movable elastic surface that moves up and down, and the tip portion is pushed down to the rotary rectifying plate (2) side, so Low resistance. On the other hand, the flow in the opposite direction, that is, from the tip portion, flows between the scale elastic blades and the rotary rectifying plate, and the tip portion is pushed open to receive a large resistance from the flow. Since this difference in resistance is generated on both surfaces of the rotating shaft (1) or the rotating shaft (11), the difference in resistance becomes a couple and a rotating force is generated on the rotating shaft. In FIG. 1, the flow parallel to the screen rotates clockwise in all directions, up, down, left, and right. If the direction of the scale-shaped elastic blade is reversed, that is, the direction from the fixing hole (6) to the tip rotates in the opposite direction. When installed on the current plate (2), it rotates counterclockwise.

In the embodiment shown in FIG. 4, the rotating shaft (1)
A stationary flow straightening plate (3) is installed at the lower end of a support pipe (9) having a built-in structure, and a scale turbine is connected in series with a rotating shaft (1) below the stationary straightening plate (3).

In the embodiment shown in FIG. 5, the rotating shaft (1)
An elbow (12) is connected to the lower end of a support tube (9) having a built-in shaft, and the rotating shafts (1) and (11) are set vertically by engaging a bevel gear inside the elbow, and the rotating shaft (11) is a bearing. (5) A rotary rectifying plate (2) having scale-type elastic blades (4) attached to the outside of the elbow (12) via an elbow (12). A plurality of connecting tubes (15) are connected to a rotating shaft (11) projecting to the outside. Insert and secure with pins (8). The stationary rectifying plate (3) has a configuration fixed to the right frontage of the elbow (12) through the stud bolt (14) and is referred to as an L-shaped squirting power generator. FIG. 6 is a configuration diagram showing an embodiment of an I-type insulated power generator.

[0011]

Since the present invention is configured as described above, it has the following effects.

The upper part of the rotating shaft (1) is connected to the generator in the atmosphere, and the lower part is connected to the scale turbine in the water,
The device can be manufactured easily. Also, one stationary rectifying plate (3) and a plurality of rotating rectifying plates (2) are arranged in parallel, which has an effect of preventing turbulence of a water flow flowing through the scale turbine.

[0013] Since the generator is small and portable, it can be used for emergency evacuation and emergency placement. Also,
The size and number of scale-scale elastic blades of the scale turbine can be freely set, and the size and number of rotary rectifying plates can be freely designed, so that the output can be selected as required.
