Description

The present invention relates to a renewable energy turbine that rotates at high speed with a very small amount of water or air, which enables small-scale power generation.

The mainstream of power generation uses steam turbines such as thermal power generation and nuclear power generation.

However, there are problems with both power generation methods. Thermal power generation has a problem of carbon dioxide emissions, nuclear power generation has a problem of nuclear waste, and high-concentration nuclear waste must be isolated and managed for tens of thousands of years. In particular, thermal power generation is said to need to be stopped urgently because it emits a large amount of carbon dioxide, which causes global warming. It is said that the cause of abnormal weather these days is global warming, and once warming begins, water vapor, which is a greenhouse gas, increases, which causes a runaway state in which carbon dioxide contained in the atmosphere further increases. It is.

On the other hand, when it comes to power generation using natural energy, there is a problem that hydroelectric power generation alone is not enough, and wind power generation and solar power generation are affected by the weather.

As a remedy for this, it is conceivable to popularize relatively stable hydroelectric power generation, geothermal power generation, and wave power generation. There was a problem that the amount of capital investment was enormous because it required a facility to handle the power generation.

The problem to be solved is that the facilities for hydroelectric power generation, geothermal power generation, and wave power generation are large-scale.

The present invention includes a rotary magnet device that converts reciprocating motion into rotary motion using a permanent magnet, and also includes a reciprocating motion mechanism that reciprocates with a fluid substance such as water or air, and links the two appropriately in terms of drive and feedback. By doing so, it is characterized in that it is configured to rotate even with a small flow rate if there is a fluid substance having a certain pressure.

Since the renewable energy turbine of the present invention is small, can be used for both gas and liquid, and rotates at a small flow rate, hydroelectric power generation, geothermal power generation, and wave power generation can be made extremely small. By the way, wave power generation is used for pumping to apply pressure to air or water, instead of directly converting the vertical motion of the wave into rotational motion. If such small-scale power generation spreads to each region or household, it should greatly contribute to global warming countermeasures.

FIG. 3 is an explanatory diagram showing the relationship between the magnet on the rotating body and the stator magnet. FIG. 4 is an explanatory diagram showing the relationship between the magnet on the rotating body and the stator magnet.

This will be described using a bar magnet having a length of 3 cm, which is generally sold.

FIG. 1 is a side view and a plan view showing a partial cross section of an embodiment of the apparatus of the present invention, and the cross section is a reciprocating motion mechanism powered by fluid pressure.

The reciprocating motion mechanism consists of a pressure chamber filled with a fluid substance and a cylinder, and a switching valve 2 is built in the pressure chamber and a piston 4 is built in the cylinder. Thick arrows indicate the flow of fluid.

Further, 16 magnets are fixed to the rotating magnet board 6 in a circular shape, and half of them have opposite polarities. By the way, the magnet expresses the north pole in a dark color. Further, these 16 magnets will be referred to as rotating magnets.

Since the stator magnet 7 needs to have a width equal to or larger than the arrangement interval of the rotating magnets, in this embodiment, it is composed of four magnets and a fixing member for bundling them.

Further, the stator magnet 7 must be configured to move in a direction against a large force generated between the stator magnet 7 and the rotating magnet, but since it is desired to carry out this with the smallest possible force, the vicinity of the center of the magnet is as shown in the figure. It is rotatably supported, and a part of the magnet fixing member functions as a lever, and by tilting it, the same effect as movement is realized.

The pressure direction of the piston 4 that drives this lever is switched by the switching valve 2, and the optimum timing for maintaining the rotation is transmitted to the switching valve 2 by the feedback link 9 from the crank provided in the rotating body.

As shown in FIG. 2, the lever and the piston 4 are connected via the drive link 10, and the two stator magnets are connected to each other by the connecting rod 11.

As shown in FIG. 3, the height of the rotating magnet on the rotating magnet board is not constant. The reason is to maintain the rotation, and at the same time, it also has a role of determining the rotation direction, which is the most important feature of the present invention.

FIG. 3 is an explanatory view showing the force applied to the stator magnet with respect to the rotating magnet at four important positions ABCD of the rotating magnet board 6 by arrows. There are several cases where the height of the stator magnet is different at each position, but the rotational moment is ignored.

A-1 and A-2 show that if the height is maintained at this level against the vertical force, there is no big difference in the force applied in the vertical and horizontal directions even if the height is slightly different. ing.

B-1, B-2, and B-3 indicate when the stator magnet comes to the place where the polarity of the rotating magnet is reversed. In any case, no force is applied in the vertical direction, but B in the horizontal direction. -1 indicates that it becomes a brake, B-2 indicates that it is in a neutral state, and B-3 indicates that a force is generated in the direction of rotation with a considerable force. In order to avoid the braking state, the stator magnet 7 always operates against the force in the vertical direction so as to avoid the state of B-1.

The description of C and D will be omitted because the vertical forces are only opposite.

FIG. 4 is a diagram showing a case where the runout width of the stator magnet is large and a case where the runout width is small.

CASE-1 shows a case where the rotation speed of the rotating body is reduced because the pressure of the fluid material is weak or the load is large, and therefore the operating width of the piston 4 is increased.

CASE-2 shows a case where the rotation speed is increased and the operating width of the piston is reduced due to the strong pressure of the fluid substance. In either case, the rotation is maintained by avoiding the brake states of B-1 and D-1.

Power can be generated by installing a coil in the vicinity of the rotating magnet board 6, or by connecting another small generator to the crankshaft 8. In this way, if water in a high place is connected with a hose or the like, it becomes an ultra-small hydroelectric power generation device. In the case of geothermal heat, the ejected steam may be connected as it is. Wave power is used by compressing air by pumping or pumping water.
