Wind Power Generation System which can convert the horizontal wind to upward through the funnel to collect wind blowing from any direction}

The present invention relates to a vertical axis wind power generator that efficiently utilizes the kinetic energy of the wind flowing around a high-rise building in the mountains, the sea or the city, and more particularly, the kinetic energy of the wind flowing in the atmosphere due to the difference between high pressure and low pressure. Regardless of collecting wind blowing horizontally, it converts into vertical upward airflow flowing through a constant ventilation pipe to drive wind turbines on the vertical axis, and wind turbines that transfer electricity from wind turbines to high-efficiency generators to convert horizontal wind into electricity to vertical airflow. Present wind turbines.

The windmill, the core technology of the wind turbine described above, is the first prime mover developed by mankind with aberrations, and has been used for milling and pumping as well as processing plants in many fields for thousands of years. After the industrial revolution, which was a revolution of power, it was pushed out by steam engines.

However, even before 300 years since the Industrial Revolution, the spread of heat engine devices that obtain powerful and fast rotational power has been rapidly spreading, burning fossil fuels, burning oxygen in the atmosphere, and releasing toxic exhaust gases including carbon dioxide. In the reality that the global environment is devastated by energy waste, the collective consciousness of mankind is turning its attention to wind power generation using natural wind as the energy source of the sun as an alternative to clean energy.

Power generation methods that produce the most safe and convenient electric energy in the industrial society include hydroelectric power using water potential energy, thermal power generation using thermal energy of fossil fuels, and nuclear power generation using nuclear power.

However, these power generation methods require an enormous amount of heat energy to make large power plants and the fluids used to run them.

As fossil fuels such as petroleum and coal as energy sources used in thermal power generation, they are more dependent than other fuels, causing problems such as exhaustion of resources.

In particular, nuclear energy or fossil fuels such as petroleum and coal that emit radioactive wastes are the main causes of global warming by destroying the ozone layer.

In addition, although fossil fuels such as oil and coal are causing environmental pollution in the atmosphere, they are highly dependent on other fuels, depleting energy resources and worsening environmental pollution, thereby threatening human survival.

Due to the use of heat engine equipment, various pollutants are polluting the atmosphere by exhausting resources and burning oil and coal.In order to prevent various disasters and environmental pollution caused by global warming, fossil fuels such as oil and coal are not needed. There is a need for a rotary power unit that produces electricity.

As described above, the prime mover that does not require fossil fuels such as oil or coal includes wind turbines, hydro turbines, tidal turbines, and the like, and the most easily applied power generation method flows from high pressure to low pressure in the atmosphere. It can be said that the wind power generation using the power of the wind turbine using the power of the wind.

In the aforementioned wind power generation, wind energy is converted into mechanical energy by a windmill to drive a generator to generate electricity. The rotational power of the wind turbine varies depending on the wind speed and wind speed of the windmill (wind turbine). In winds with windmill blade length of 1m and wind speed of 10m / s, the wind turbine output is about 1kW.

Such wind power is a pollution-free energy source that does not involve waste, and wind power is used for power generation of lighthouses on remote islands with many winds. In addition, the power generation facility is very simple to install compared with other power generation devices, and there is an advantage that no waste is generated in the wind power generation device.

However, the wind turbine according to the prior art is rotated by the force of the wind in contact with a small number of propeller blades installed in the plane of the rotation radius, the method for obtaining a larger wind power output is the blade (blade) of the windmill Since there is only a method to increase the length and length, the price of the wind power generator installed in the extra-large is expensive and low power generation efficiency compared to other power generators, there is a problem of high cost and low efficiency. In addition, the propeller of the wing-type windmill is installed on the top of the installation tower and is exposed to direct contact with the outside, so if the object is blown directly by the unexpected wind or gust, it will directly damage the propeller, causing external damage to the propeller. It causes serious functional problems.

The present invention is to solve the above-mentioned problems, the horizontal blowing wind of the north-west and north-west guides in the vertical ascending direction by the wind collecting structure, and enters the inlet of the large cross-sectional area to guide the low-density low-speed wind into the high-speed wind It collects a lot of wind and guides it to a narrow ventilation pipe to increase the speed of the wind, converting it into an updraft, and turning the wind flowing in a straight line from the cylinder's ventilation pipe in the bypass spiral direction to produce a tornato to maximize the wind speed. The bladeless wind turbine is applied to drive the turbine, so there are no protruding blades, so there is no breakdown, the wheel balancing is stable, the vibration noise is low, and the wind speed is over 20m / sec. By bypassing the wind to the door damper installed in the ventilation duct, Preventing operation in advance because it is a safe house punggwan using wind power generator provides changing horizontal wind to drive the wind turbine generator to the air pockets.

In order to achieve the above object, a wind turbine using a vertical rise airflow of a wind collecting structure according to an embodiment of the present invention has an inlet formed at a lower side thereof, and winds the wind blowing in a horizontal direction through the inlet toward the center.

It is formed in eight, characterized in that the wind guide fixing piece is formed in plural, the impeller attached to the outer cylindrical rotor is also formed in plural.

As described above, the present invention guides the horizontally blowing winds of the east, west, north and north in a vertical ascending direction by the wind-up structure. By gathering in one direction to increase the density, the speed of wind movement is increased, and the angle (blowing angle) of the wind guide fixing piece is made into a specific angle.

For example, the wind guide stator nozzle is 30 degrees, and the impeller is installed and installed at an inclination angle of 45 degrees, which is responsible for the rotational function and the compression function. In comparison, the wingless big bang turbine increases the rotational force of the wind turbine in which the impeller (blade) is coupled to the outer cylindrical shape, thereby greatly improving the efficiency of the wind turbine.

In addition, the present invention is a structure of the impeller coupled to the cylindrical of the new concept as a wingless impeller protruding as compared to the windmill driven in direct contact with the wind as in the prior art, there is no damage to the wing damage and there is no vibration noise in the configuration of a stable wheel balancing, The wingless cylindrical wind turbine has a long and safe device life and can carry general high efficiency, high performance wind power generation from the smallest to the largest.

In addition, the present invention adjusts the position of the damper to open and close the wind to focus more wind to rotate the wind turbine more powerfully, so that more power generation can be carried out, on the day of high wind winds due to the typhoon wind turbine rotor overspeed This may cause damage to mechanical equipment and electrical equipment. To prevent this, open and close the damper to block the wind so that the output voltage of the generator is properly adjusted to prevent faults caused by overspeed rotation and high voltage. It is effective in preventing and increasing the overall life of the device.
