Description

  The present invention relates to a fluid-driven small power generator, and more particularly to a power generator having a simple structure and extremely high power generation efficiency.

  A conventional fluid-driven power generation device is provided with a rotatable wing piece in the tap water flow pipe, and the axis of the wing piece is coupled with the rotor of the generator body to generate power. Achieve the efficacy of

The conventional fluid drive type power generator has the following drawbacks.
Since the rotor centering the generator body on the outside of the axis of the blade piece always transmits the rotating shaft or gear, and the rotating shaft or gear also passes through the wall of this water flow, this kinetic energy transmission In addition to having very high wear and tear, it affects the efficiency of the overall power generation, and at the same time the water flow can leak and become contaminated by drilling holes.
Since the blades have a very large gap between the inner walls of the water flow line, some water flows do not act on the blades when passing through the gaps, and therefore the power generation It also affects efficiency.
While all wings are in water and the forward water flow that is flowing provides a moment of force to rotate the wings, the other side of the wings is still in water, The resistance force can only turn the winglet slowly at a very low rotational speed, and most of the benefits are not used to cut the magnetic field lines, and the efficiency of power generation is low.

  The main object of the present invention is to provide a fluid-driven small power generator, which is directly driven by a rotor with a fluid and further reduces the diameter of the fluid outlet. For this reason, the fluid can be ejected intensively on the rotor and the kinetic energy of the fluid can be sufficiently utilized, so that a relatively good power generation efficiency is produced.

  Another object of the present invention is to provide a fluid-driven small power generator, which is a wing-type rotating device by combining a permanent magnet and the upper and lower lids of a wing. By increasing the weight of the child, it acts as a flywheel, and further effectively increases the inertia of the airfoil rotor and increases the stability of the rotation.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(First Example)
1 to 6 are views relating to a first embodiment of the present invention. The first embodiment includes an inner cylinder 1, an outer cylinder 2, a coil stator 3, a permanent magnet 4, an airfoil rotor 5, a nozzle device 6, and a circuit board 7. The inner cylinder 1 forms a cylinder by joining two semi-inner cylinders 11, and the upper end thereof is in contact with a fluid inlet that receives fluid. A shaft hole 115 and an annular groove 114 are provided on the inner side of the semi-inner cylinder 11. The outer side of the semi-inner cylinder 11 includes a linear convex edge portion 112 and a stereotactic groove 113. The outer cylinder 2 forms a cylindrical body by connecting the vertical side convex edge 215 and the vertical side concave groove 216 corresponding to the edges using the two semi-outer cylinders 21. The inner edge at one end of the semi-outer cylinder 21 is provided with a groove 213 for positioning the outer convex edge 111 of the inner cylinder 1, and the outer edge of the end is provided with an outer screw pattern 214. One half outer cylinder 21 is provided with a push button 217 of a switch. The stator 3 of the coil is wound between the linear convex edges 112 of the inner cylinder 1. Moreover, at least one of the linear convex edges 112 is formed with a notch 121A for connecting the coil stator 3 to the circuit board 7. The wing rotor 5 includes a wing upper lid 51, a wing lower lid 52, a pivot 511, and a permanent magnet 4, and is rotatably provided in the shaft hole 115 of the inner cylinder 1 by an axle joint 511. The nozzle device 6 includes a nozzle 61, an elastic joint 62, and an upper lid 63. The nozzle 61 has a convex edge 611, an inlet 612, and an outlet 613. The convex edge 611 is fitted into the annular concave groove 114 of the inner cylinder 1 for localization. The cross-sectional area of the inlet 612 is larger than the outlet 613, and the outlet 613 moves away from the central axis of the nozzle 61, thereby accelerating the water flow and concentrating the water flow, leading to one side of the airfoil rotor 5. As a result, the maximum rotation distance is generated. The hollow portion 631 and the upper lid 63 having the inner screw pattern are screwed into the outer screw pattern 214 of the outer cylinder 2. Thereby, the elastic bonded article 62 can be locked to the outer convex edge portion 111 of the inner cylinder 1. The elastic joint 62 is provided with an elastic expansion / contraction port 621 for guiding fluid to the pipe end (for example, the faucet 8). The circuit board 7 is provided on the upper edge of the stereotaxic groove 113 on the outer periphery of the inner cylinder 1 and has at least a plurality of diodes 71. You may provide the charging seat for couple | bonding a rechargeable battery as needed. A plurality of light emitting diodes 73 are also provided on the bottom side of the circuit board 7. The circuit board 7 includes a switch 74 and a push button 217 for the switch of the outer cylinder 2, and the switch 74 and the push button 217 for the switch of the outer cylinder 2 correspond to each other. The circuit board 7 is controlled.

  As shown in FIG. 6, during use, the faucet 8 as the pipe end introduces a fluid, and the fluid is concentrated and guided through the nozzle device 6, and the airfoil rotor at an oblique position. The wing rotor 5 is driven and rotated by accelerating the impact on the outer side of 5 and having an excellent moment of force. Therefore, the permanent magnet 4 in the airfoil rotor 5 changes the magnetic field around it. At this time, the stator 3 of the outer peripheral coil is sensitive to an alternating voltage because the changing magnetic field generates a magnetic flux due to a change in time. The AC voltage is rectified to a DC voltage via a bridge rectifier composed of a plurality of diodes 71 on the circuit board 7. This provides for charging the rechargeable battery 72 and for the electrical energy (in the space under the light) of the lighting that causes each light emitting diode 73 to emit light, and after pressing the push button 217 of the switch, the switch 74 In conjunction with this, it is possible to control whether the DC voltage is output from the light emitting diode 73.

  In the structure of the first embodiment, not only can the weight of the airfoil rotor 5 having a relatively large rotational inertia mass be increased through the structure in which the airfoil rotor 5 encloses the permanent magnet 4. , Can increase the stability of turning. Further, contamination due to contact of the permanent magnet 4 with the fluid can be prevented. Since the airfoil rotor 5 and the permanent magnet 4 are provided directly in the fluid passage, not only can the friction and transmission wear be reduced by rotating effectively, but also the efficiency of power generation can be reduced. Can be increased. Further, it is not necessary to make a hole in the wall surface of the fluid passage, and it is possible to avoid the leakage of the fluid and the concern of contamination. The airfoil rotor 5 can be integrally molded outside the permanent magnet 4.

  In the structure of the first embodiment, since the nozzle 61 and the circuit board 7 are assembled using a fitting type, it has convenience in assembling. The length of the inner cylinder 1 is larger than that of the outer cylinder 2. Therefore, when the fluid flows out from the lower side of the inner cylinder 1, the fluid does not jump up to the position of the inner convex edge 212. Use safety and longevity can be secured.

  In the structure of the first embodiment, when actually utilized, as shown in FIG. 6, the liquid fluid can be placed at the outlet of the liquid fluid line to direct the liquid fluid downward (ie, in a vertical arrangement) or vertical. It can be made to flow out in the direction other than the arrangement. The cross-sectional area Ao of the liquid fluid outlet end of the inner cylinder 1 is preferably larger than the cross-sectional area Ai of the fluid conduit inlet end led to the elastic joint 62. As a result, air chambers 10, 10A, 10B are formed around the airfoil rotor 5 through the gap 10C below the inner cylinder 1, so that one side of the airfoil rotor 5 into which fluid is poured The reverse acting force that caused the back flow of the liquid fluid can be removed without disturbing the rotation. Therefore, the rotational speed of the airfoil rotor 5 is increased, and the power generation efficiency is further increased. That is, according to the results of experiments conducted by the inventor many times, when the cross-sectional area Ao of the outlet end of the inner cylinder 1 is larger than the cross-sectional area Ai of the fluid conduit inlet end, high efficiency can be achieved.

  When the above-described structure according to the first embodiment is applied to a gaseous fluid, the situation is similar to that of a liquid fluid, and thus the related description is omitted.
