Description
The present invention relates to a vertical axis wind power generation device, and more particularly, to a vertical axis wind power generation device that can be installed on the coastal surface of the seashore and the wind direction of the sea wind and land wind in the day and night always obtain the maximum power generation efficiency.
In general, the wind power generator rotates the blades by the wind force, the force of the wind to generate electrical energy by the rotational force generated at this time. Such a wind power generation device basically consists of a supporting structure for supporting a rotating blade and a rotating shaft for generating a rotational force by the wind.
According to the shape of the rotating shaft rotated by the rotary blades are divided into a horizontal axis wind power generator and a vertical axis wind power generator.
In general, horizontal axis wind turbines have a propeller-type rotating wing installed at the peak of a high host, which cannot achieve efficiency of 60% or more, and have a high initial installation cost due to high host installation cost.
Therefore, in recent years, the research and development of the vertical axis wind power generator rather than the horizontal axis is actively progressing.
In the vertical axis wind turbine, a plurality of blades are disposed at equal intervals on a vertical axis in a turbine-type rotor blade unit. Therefore, in order to minimize the wind resistance at the rotational radius facing the wind direction and the rotation progress direction of the rotor blades, the blade section is formed in a convex curved shape in the rotation progress direction. Therefore, in the forward direction, the wind is held as much as possible to obtain maximum rotational propulsion, and in the reverse direction, the wind resistance is minimized.
The structure of the rotor blade of the conventional vertical wind power generator is disposed at a certain height from the ground surface, and the surrounding space is sufficient, so that the wind direction is constant in the air, but the wind direction is not constant and changes frequently at the surface of the uneven surface. Due to the frequent changes in various forms such as vortices or rising air, the structure of the rotary wing suspended at a certain height from the ground surface could not sufficiently increase the energy conversion efficiency on the ground surface.
In addition, the coastal areas are unexpectedly super strong winds such as typhoons, so structural strength must be maintained to withstand the strong winds.
An object of the present invention is to provide a vertical wind power generator having a sufficiently high energy conversion efficiency in the wind direction is changed to day and night by varying the wind characteristics installed on the shore surface of the coast.
Another object of the present invention is to provide a vertical wind power generator that can withstand very strong strong winds such as typhoons or gusts even if installed in the coastal region by making the length of the vertical axis as short as possible.
Still another object of the present invention is to provide a vertical wind power generator capable of guiding smooth rotation of the blade having a height longer than the length of the vertical axis and structurally stable by supporting the rotary wing assembly with the vertical guide roller.
Still another object of the present invention is to provide a vertical wind power generation device that can lower the initial installation cost because it is not necessary because the host facility is installed on the ground surface.
Still another object of the present invention is to provide a vertical wind power generator that is easy to install and maintain by placing a generator on an upper vertical shaft.
In order to achieve the object of the present invention described above, the apparatus of the present invention has a rotating blade assembly coupled to the shaft support housing and the shaft support housing is rotated by wind power. The shaft support housing has a lower shaft support and an upper shaft support disposed at regular intervals in the center of the main frame and the main frame, and a vertical axis disposed vertically between the upper and lower shaft supports. The rotary wing assembly has a plurality of blades arranged concentrically on the vertical axis and having a circular upper and lower support portions having the same radius of rotation, and equidistantly spaced on the concentric circles at regular intervals between the upper and lower support portions. Each of the plurality of blades includes an arcuate upper side support coupled to the upper support to be positioned on the first radiation, an arcuate lower support coupled to the lower support to be positioned on a second radiation advanced at a certain angle than the first radiation. And a curved plate which is fixed between the upper and lower supporters and is convex in the rotational direction. Here, the first radiation and the second radiation refer to straight lines extending radially from the center of the rotation axis.
In the present invention, the rotor blade assembly is a plurality of vertical frames for vertically extending from the upper support of each of the plurality of blades to support a vertical gap between the upper and lower supports, and a plurality of vertical frames extending from each of the plurality of vertical frames to rotate on the vertical axis And a plurality of horizontal arms for securing the wing assembly to the vertical axis.
In addition, the rotary wing assembly is preferably rotatably supported by a plurality of guide rollers fixed to the bottom and ceiling of the body frame, respectively.
Each blade should have a slit that vertically bisects along the twisted slope in the center of the curve.
In the present invention, the generator is built in the inner space of the upper shaft support. This allows the generator to be placed on top of the vertical axis so that the generator can be lifted and installed by a crane without disassembly and assembly of the rotary vane assembly and easily lifted during maintenance.
In the present invention, since the blade of the rotary wing assembly is convex with respect to the rotation progress direction to form a warp inclined in the forward direction to form a structure that bears the wind as much as possible in the rotation radius of the wind direction, and meets the wind in the rotation radius of the reverse direction of the wind progression By minimizing the area, energy conversion efficiency can be maximized. In other words, the turbine-type rotor blade assembly rotates smoothly even in a region where the wind direction is severely changed and the wind speed is low, thereby efficiently generating power through continuous and stable energy conversion.
It is economical because initial facility investment cost can be saved because there is no need to install high host because it is installed on the surface in order to make full use of wind characteristics of coastal area.
In addition, the length of the vertical shaft shorter than the height of the blade can reduce the torsional force applied to the shaft to minimize the damage of the shaft bearing can extend the life of the device and reduce maintenance costs.
In addition, the present invention has a structure in which the generator is built into the inner space of the upper shaft support portion, so that the generator can be lifted and installed by a crane without disassembly and assembly of the rotary wing assembly, thereby facilitating construction convenience and convenience during maintenance. .
Therefore, in Korea, where three sides face the sea, small-scale wind power generation is possible for farms and regional units in coastal islands.

Referring to the drawing, therefore, when the blade starts to enter the forward rotation radius, as shown in Fig. 8, since the blade is opened from the lower side to the forward wind, since the wind enters from the lower side of the blade and the bottom is blocked by the ground, the inner surface of the curved plate is closed. As it twists up the reverse slope, it forms an upward airflow and exits upward. At this time, as the upward air flow twists the reverse slope, the force generated in the rotational direction on the inner surface of the curved plate is doubled so that the rotational driving force is doubled.
The blade is subjected to maximum rotational propulsion both up and down in a position perpendicular to the wind direction in the forward rotation radius.
The lower side of the blade begins to exit the forward radius of rotation, but the upper side is still open and forward rotational force is applied.
When the blade starts to enter the reverse rotation radius, the upper side still enters the state of receiving the forward wind, so it starts to receive the wind resistance, but still enters the state of the rotational force acting in the forward direction. In addition, the wind hit the lower side is to be deflected along the inclined surface twisted from the lower side to the upper side to minimize the wind resistance.
Even if the blade is located at a position perpendicular to the wind direction in the reverse rotation radius, the wind is combed by the streamlined curved surface and twisted slopes and slits to minimize the wind resistance on the blade.
Therefore, in the reverse rotation radius, the wind is deviated by the sloped slope structure to minimize wind resistance, and in the forward rotation radius, the wind is maximized, and the inflowed wind is converted into the rising air along the sloped reverse slope to escape upward. By guiding them out, they can maximize rotational propulsion.
Therefore, in coastal areas, the temperature of the land which warms up quickly during the day is higher than that of the sea, which is relatively low. Therefore, the wind is the sea breeze (the wind blowing from the sea) on the ground. As the wind blows, the sea breeze blows over the land. In order to maximize the wind characteristics of the coastal region as described above, the blade surface is formed so that the lower side opens faster than the upper side in the forward direction with respect to the wind direction.
In addition, the
While the present invention has been described in connection with what is presently considered to be practical and exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
