If the wind speed of nature is not high, the power generation effect cannot be obtained, so the installation location had to be greatly restricted. In addition, when the wind power increased, the rotation drive part could not withstand high heat, so the power generation work had to be stopped temporarily.

れることにより発電効率を高めることを可能にした。[Means for Solving the Problems] This system is based on the principle of accelerating a fluid when passing through a narrow cross-section area according to Bell-Nouy's law by installing a case outside the rotor as a main means for accelerating wind speed. The power generation efficiency is increased by increasing the rotating force of the rotor by utilizing it, so the device can be made compact and the manufacturing cost can be saved accordingly. Further, another rotor that is interlocked with the rotation of the rotor is filled with a liquid around the rotor and is rotated to convert the wind energy into the rotational energy of the liquid with a relatively small resistance force, and at the same time, a solid container for containing the liquid is provided. The liquid also rotates and absorbs the excess energy of the natural wind as the rotational energy of the solid, so the need for the so-called feathering phenomenon in which the wind with a wind speed above a certain level is released as the cutout wind speed and power generation work is suspended during that time It is a wind power generation system that is equipped with a regulator that removes the power and continuously enables power generation work, and adjusts the fluctuation range of power generation depending on the strength of the wind power. In addition, since the current wind power generator uses a propeller as a rotor, compared with the fact that the utilization rate of natural energy is low due to the relatively small contact area with the natural wind, the turbine-shaped rotor is used. By using more natural wind and making contact with it, it was possible to increase the power generation efficiency by incorporating more natural energy into power generation.

解放する。[Function] Since the case is installed in front of the rotor and the rear of the case is opened, the wind speed increases as much as the frontage becomes narrower. This can be explained by Bell-Nouy's law, which is the basic principle of fluid motion, because the product of velocity and width is constant. Therefore, even if it is the minimum wind speed required for power generation, the wind speed can be increased by combining the case and rotor conveniently, so the so-called cut-in wind power can be lowered by expanding the range of wind speed required for power generation to a smaller speed. This relaxes the conditions of the site of installation of the wind power generator, thereby releasing the topographical constraints more widely.

トがかかります。2. Description of the Related Art Conventional wind power generators increase power generation by lengthening the blades of propellers.
The reality is that the size of the equipment increases and the cost increases, and the location of installation is also inconvenient because the wind power is concentrated in polar regions. This is because the power generation capacity is small compared to other thermal power generation and nuclear power generation. In order to increase the power generation capacity, there is a method of covering the propeller to speed up the wind speed to increase the power generation, but if the blade is lengthened the rotating area of the propeller becomes large and the wind speed slows down according to Bernoulli's theorem, so it is large It cannot be applied to power generation and has not been put to practical use. Taking the most common three-blade blade of a conventional propeller as an example, the total angle of the three blades is within 30 °. Even though the wind energy of 30 ° out of 360 ° is used for power generation, it is thrown away without using the wind energy of 330 ° later. Therefore, the power generation is still small. In addition, excessive wind power causes the wind turbine to stop generating power and lowers the power generation efficiency, and at the same time, the cost of the equipment for that is high.

可能にして発電の効率を下げない方法です。[Means for solving the problem] The decisive defect of conventional wind power generation is that the power generation is small. There are two common methods currently used to increase the output of this wind power generation. Of the two methods, the most practical method is to increase the length of the blade of the wind turbine type propeller because the output is proportional to the square of the radius of the propeller. Since the cost is proportional to the cube of the radius, the power cost increases, so there is a limit and it is not a fundamental solution to the output shortage. Next, as another method of increasing the output, a method of covering the wind turbine type propeller to accelerate the wind speed to increase the power generation is technically unsuitable for large-scale power generation as described in the previous section. . The technical deficiency is that the wind power generator has a problem in that the wind speed of natural wind is increased by increasing the output by combining the slit machined in the front wall of the box containing the wind turbine and the turbine type wind turbine. solved. First, a theoretical consideration of the basics of the effectiveness of this method is as follows. You That is, the Bernoulli's theorem is applied to the wind speed and pressure in front of the box and the wind speed and pressure passing through the slit on the box surface as follows. Each letter is U: wind speed, ν: wind speed passing through the slit Σζ: loss coefficient associated with the contraction of the slit part and the rapid expansion of the box, and the contraction of the slit part is {(1 / C c ) -1} 2 : C
c = 1.0 (when the corner is rounded), the loss of sudden expansion is
ξ {1- (a / A)} ξ = 1.0 a: slit cross-sectional area, A: box cross-sectional area, P 1 -P 2 : pressure difference between box front surface and inner surface Cd: box resistance coefficient, Cd = 2.0 (This is a case of a two-dimensional rectangle and may be a small value.) From this, the increase rate of wind speed from Equations (1) and (2) is With a / A = 0.1, a simple trial calculation The results are obtained, but it is theoretically said that the wind speed tends to accelerate until the tiredness. In fact, due to the fact that the lift force as the component force of the wind force exceeds the propulsive force of the same component by several tens of times. It is possible to give momentum to the torque of the windmill to accelerate it. In fact, in the wind turbine type experimental machine that we made, we obtained a 10 times acceleration result on a power generation basis simply by covering the propeller. In addition, considering that the results of confirmation that the lift force is 50 times the propulsion force have been reported in the research institute of Delft University of Technology, a large amount of power generation can be obtained by the wind power generation method. In addition, because the regulator that we have developed stores excess wind power as rotary inertia energy in the order of gas, liquid, and solid, it is possible to continue power generation work without suspending the feathering phenomenon or power generation work. This is a method that does not reduce the efficiency of power generation.

By releasing, the electric power will be greatly reduced economically and it will be very useful for exhaust gas regulation.
