DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wind power generator having a rotating body which rotates by receiving wind from wings.

[0002]

2. Description of the Related Art A conventional wind power generator converts a kinetic energy of the wind into a rotating motion of a rotating body by directly blowing the wind to the wings of the rotating body, thereby forming a generator connected to a rotating shaft of the rotating body. It was rotated to generate electric energy (see, for example, JP-A-54-133203).

[0003]

The wind power generator rotates the rotor of the wind power generator by wind, converts the kinetic energy of the wind into the rotational motion of the rotor, and further operates the generator to generate electric energy. However, the wind blown from the rotating body after rotating the rotating body still has much kinetic energy. For this reason, the conventional wind power generator has a problem that kinetic energy of wind cannot be efficiently converted into rotational motion.

[0004] The present invention provides a wind power generator that can obtain more energy from the wind.

[0005]

In the wind power generator according to the present invention, a liquid such as water is injected into the wind,
Part of the kinetic energy of the wind is given to water, which has a greater mass per unit volume than the wind, and the kinetic energy of the water is also applied to the rotating body of the wind turbine to reduce the kinetic energy of the wind. This is to convert the rotational motion of the rotating body efficiently.

[0006]

[Function] When water given kinetic energy from the wind collides with the wings of the rotating body, it does not flow downwindward while retaining much kinetic energy like wind, and the wings due to the viscosity and wettability of the water Most of the energy is converted into rotational motion of the rotating body by attaching to or bouncing off the surface. Also, water accelerated by a large amount of wind has a much higher kinetic energy per unit volume due to its much higher density than the wind, so the energy given to the rotating body is also greater than that of a wind of the same volume. Therefore, the kinetic energy of the wind can be efficiently converted into the rotational motion of the rotating body.

[0007]

An embodiment will be described with reference to the drawings. The wind turbine generator 1 shown in FIGS. 1 and 2 has fixed wings 4 that rectify the wind in a direction to rotate the rotating body 3 in one direction around a rotating body 3 having the wings 2 that receive the wind. The support 8 fixed to the lower fixing plate 7 having the upper fixing plate 5 and the drainage port 6 at a suitable interval, and fixed to the lower fixing plate 7 is fixed to, for example, a flat ground 9 around which there is no obstacle. Have been.
The nozzle 10 for discharging water is provided with a discharge port 11 of the nozzle 10.
Is fixed to a flat ground 9 so as to surround the wind turbine generator 1 and is attached to a column 12 which also serves as a pipe for sending water to a nozzle 10. In FIG. 2, the number of nozzles 10 is omitted for the purpose of making the entire device 1 easier to understand. The mounting plate 13 fixed to the column 8 includes a storage tank 14 disposed below the drainage port 6 of the lower fixing plate 7,
The equipment connected by piping 17 in the order of filter 15 and pump 16 is fixed. Pipe 17 on the discharge side of pump 16
Are laid in the ground in a branched manner, and are connected to the respective nozzles 10 via columns 12 which also serve as pipes. The rotating body 3 is a rotating shaft 1 rotatably held by a bearing 18.
9, a waterproof generator 20 fixed to the mounting plate 13
It is connected to the. The reason why the outer peripheral end and the inner peripheral end of the lower fixing plate 7 are bent upward over the entire circumference is to prevent water remaining in the lower fixing plate 7 from flowing out.

In the wind power generator 1 shown in FIG.
Storage tank 1 supplied to nozzle 10 via pipe 17 by 6
After the water of No. 4 is discharged in the form of a mist or a shower from the discharge port 11 of the nozzle 10, it is accelerated while being swept by the wind flowing into the apparatus 1, and hits the wings 2 with the wind to rotate the rotating body 3. The water after rotating the rotating body 3 is shaken off by the centrifugal force generated by the rotation of the rotating body 3 and flows down to the lower fixed plate 7 together with the water attached to the fixed wings 4 and the upper fixed plate 5, and then to the lower fixed plate The wastewater flows into a storage tank 14 from a drain port 6 provided in the storage tank 7 and is collected. After the water collected in the storage tank 14 is removed by a filter 15 to remove contaminants, the pump 1
6 for recycle use. The water scattered outside the apparatus 1 or reduced by evaporation is supplied, for example, by detecting the water level of the storage tank 14 with a liquid level gauge and opening and closing a solenoid valve of a water supply pipe linked with the liquid level gauge. It may be.

Water is supplied to each nozzle 10 by installing an electromagnetic valve on the nozzle 10 or on a pipe 17 connected to the nozzle 10 and controlling the opening and closing of the electromagnetic valve in conjunction with an anemoscope so that the windward side is controlled. Alternatively, water may be discharged only from the nozzle 10 at the location where the wind is taken into the apparatus 1 from. In addition, the nozzle 1 depends on the wind speed and the rotation speed of the rotating body 3.
The amount of water discharged from 0 may be adjusted. Further, between the adjacent nozzles 10, an introduction blade for guiding water discharged from the nozzle 10 toward the fixed blade 4 may be provided. For example, a wind turbine in which plate-shaped introduction wings having one end contacting the outer peripheral end of each of the fixed wings 4 are vertically arranged around the fixed wings 4 with the front and rear directions of the introduction wings facing the rotation axis 19 of the rotating body 3. In the power generator, when the nozzles 10 are provided between the introduction blades, water discharged from the nozzles 10 can be guided to the rotating body 3 together with a large amount of wind taken in by the introduction blades.

Although FIG. 1 shows the case where the number of nozzles 10 is ten, the number of nozzles 10 can be increased or decreased as necessary. Further, the nozzle 10 may be attached to the flat ground 9 or around the place where the device 1 is installed, or may be attached to a required portion of the device 1, for example, the lower fixed plate 7, the upper fixed plate 5, or the fixed wing 4. In addition to the examples shown in FIGS. 1 and 2, the nozzle may have a form in which an opening is provided at an appropriate interval on a side surface of a pipe whose one end is closed. in this case,
The water discharged from the opening of the pipe becomes water droplets by the wind blown into the device 1, accelerates while being swept by the wind, and hits the wings 2 together with the wind. The water may be injected into the wind by spraying water into a mist by an ultrasonic vibrator instead of the nozzle.

In order to prevent the rotating body 3 from becoming heavier due to the attached water and preventing the rotation of the rotating body 3 from being suppressed, a water-repellent fluorine resin or silicone oil is applied to the wing 2 or the like. Thus, water may not easily adhere. Further, an antifreeze, a preservative, an agent for preventing the generation of algae, and the like may be added to the water in the storage tank 14.

The power generation by the wind injected with water is shown in FIGS.
The present invention may be applied to any type of wind power generator other than the wind power generator 1 shown in FIG. In addition, in a freezing or snowy season or in a cold region, it is possible to prevent the wind power generator from operating due to freezing or snow accumulation by melting ice and snow with water injected into the wind. In this case, it is effective to heat the water to be discharged or to use hot water such as a hot spring. In the above description, the case where the rotational motion of the rotating body 3 is used for power generation has been described. However, the rotation of the rotating body 3 may be used to operate a water pump and a heat generator using frictional heat.

[0013]

As described above, according to the present invention, by injecting water into the wind, the kinetic energy of the wind can be efficiently converted into the rotational motion of the rotary body of the wind power generator. More power can be obtained from the generator connected to the

Further, in cold regions, etc., by dissolving ice and snow with water injected into the wind, it is possible to prevent the wind power generator from operating due to freezing or snow accumulation.
