Abstract

A wind power generation system capable of efficiently generating a power, wherein slits (10) are provided in the front plate of a case (2) incorporating a sirocco fan type turbine connected to a generator (3) to take in natural wind so as to rotate the blades of the turbine by a wind velocity accelerated by a pressure difference caused inside and outside the front plate and inside and outside the wall of a flange (12) at the rear end of the case (2), and a wind energy discarded so far is utilized without waste for power generation by using the sirocco fan as the turbine, whereby, since an excess wind power is temporarily stored in the form of the rotational inertia force of gas, liquid (15), and solid (13) and, when the wind power is reduced, a rotational force is maintained to continue a power generating operation, a high power generation efficiency can be maintained at a high level.

Description

Description Wind acceleration type inertial power generation system

TECHNICAL FIELD The present invention relates to a wind turbine connected to a generator based on Bernoulli's fluid theorem based on Bernie's fluid theorem. At the same time as generating electricity, the excess wind power is temporarily stored by changing the form of energy into the rotational inertia of the gas, liquid, and solid phases to prevent damage to the equipment and at the same time propellers are used when the wind power decreases. Equipped with a mechanism to maintain the rotational force of the wind turbine. Technological background Conventionally, wind power generators use natural wind as they are to generate power, and have been disadvantageous in that they have strong geographical constraints and low output. In addition, power generation work is stopped in a manner that reduces wind resistance so that excessive wind does not damage the equipment, resulting in lower power generation efficiency and the need for such equipment, leading to higher costs. You. In order to increase the output of the wind power generator, it is troublesome to increase the size of the equipment. This is based on the fact that the output of wind power is proportional to the cube of the wind speed and proportional to the square of the radius of the propeller. Also, the reason that the propeller blades are often three is considered to be that the cost is low because the rotation efficiency is good and the number of blades is small in view of the propeller acceleration force. In addition, the long radius of the propeller allows the propeller to rotate even in small winds due to the large rotating area that the wind receives, so that the wind speed to generate electricity is small. However, it is economical to avoid such considerations in places where there is sufficient wind. For this reason, the installation location of the wind power generator is geographically limited, and the cost increase associated with the increase in size increases the cost of power generation and lowers economic efficiency. Due to these circumstances, wind power generators are likely to be installed in remote areas, making power transmission expensive. This is due to the fact that the location is large and the value of the land is inexpensive, which has contributed to this trend, but has led to a situation where it is difficult to find suitable places to meet the conditions. Disclosure of the invention

The present invention incorporates a sirocco fan-type windmill that connects natural wind to a generator based on the Bernoulli theorem, which is the basic theorem of fluid mechanics, and the slit that hits the wind intake opens forward. In the case where the end forms a flange wall and the rear part is open to the outside air, a differential pressure is generated between the outside and the inside of the plate in front of the case. The wind introduced through the slit into the case is accelerated due to the differential pressure generated on the outside, and the wind is accelerated to generate electricity by pushing the windmill blades. The energy of the wind is proportional to the area where the wind hits From the above, when the contact area between the wind and the propeller is conventional, there are three blades, and the expected angle is less than 30 ° out of 360 °, which is 3330 ° / 360. Instead of using the wind at the corner where the wind was expected to be used for power generation and abandoning it, we changed the windmill to a sirocco fan-type blade to use almost all the wind for power generation. Energy will be used for power generation. In addition, a cover plate is installed on the front of the wind turbine so that the wind does not hit against the rotation of the wind turbine, and half of the wind turbine is placed in front of the wind turbine. This is a windmill with a structure in which a plate is arranged so that it does not hit the wings of the windmill and does not detour. In addition, a solid container is filled with liquid on an extended shaft that is coaxial with the shaft of the wind turbine, and is connected to a bearing fitted into the wall of the case so that the weight of the solid does not fall on the shaft. A plurality of protruding plates extend toward the axis, the container is filled with liquid, and flexible wings fixed to the axis extend radially toward the ceiling of the container. When rotating by the wind, if the wind is weak, the flexible wings fixed to the shaft contact the protruding plate on the inner wall of the solid, but flex themselves and rotate in the liquid. When the wind power increases, the flexible wings and the liquid rotate while pressing on the protruding plate on the inner wall with the resultant force, so that the rotating force acts on the entire solid container, and the solid container itself rotates. Wind energy is wind energy in the form of gas, liquid, and solid rotational inertia. Temporarily stores, when the wind is weakened wind power generation system incorporating a regulating Seiki to continue maintaining the power generation as a rotational force of the shaft. Therefore, the wind power generation system can generate power much more efficiently than the conventional wind power generators, and the range that can be used for wind power generation is wide. In particular, the cut-in wind power for starting wind power generation is 1.5 m / sec. Because of its wide range, it can generate power efficiently everywhere, so it can be generated in a place close to the power consumption area, so it can be said that it is an economical wind power generation system that can save transmission fees. BRIEF DESCRIPTION OF THE FIGURES

Figures 1 and 3 are examples of cross-sectional views of the wind power generation system of the present invention. The dotted line shows the internal structure, and the solid line shows the external structure. The wind turbine blades (1) are fixed to the rotating shaft (8) and connected to the generator (3). A shield plate (11) is provided in front of the case (2) to prevent the wind entering through the slit (10)) in front of the case (2), and the flange wall (12) accelerates the wind force by the differential pressure. The rear of the case is completely open and air is flowing. The rudder (6) keeps the wind constantly vertical and generates efficient power. Also, support these devices on the ground (9) with the support (7). Figure 2 is an example of the front view of the wind power generation system of the present invention. The dotted line shows the internal structure, and the solid line shows the external structure. The wind coming in from the slit (10) turns the windmill blades (1) to generate electricity by the generator (3), and at the same time, regulates the wind power by the regulator (5) to the gas, liquid (15), and solid (13). The power is adjusted by changing the rotational inertia force in order and temporarily storing the wind power. Fig. 4 is an example of a cross-sectional view of the regulator built in the wind power generation system of the present invention. A plurality of flexible wings (16) are fixed to the extended shaft of the rotating shaft (8) of the windmill, and the protruding plate (14) protruding from the inner wall of the solid container (13) toward the rotating shaft (8) is filled. The rotating liquid (15) and the flexible wing rotate to rotate the protruding plate. Conversely, when the wind force weakens below a certain level, the projection plate rotates the liquid (15) and the flexible wings (16). BEST MODE FOR CARRYING OUT THE INVENTION

In carrying out the invention, it is effective to reduce the size and weight of the device to make the most of its features. In other words, because the windmill is a sirocco fan type, it uses about 11 times as much wind energy as conventional wind generators without wasting it. In addition, it eliminates the need for the fuser ring phenomenon due to cutout wind speed and generates electricity with a regulator. Since the work is not interrupted, miniaturization as a whole can be achieved without lowering the output, so simplification of the structure and associated cost reduction and release of geographical constraints due to wind acceleration and power generation with extremely high efficiency can be achieved. is. Industrial applicability

As described above, the power generation system is compact and capable of generating high output, but is economical in construction costs and can be used as a great source of power and energy.
