Description

Radial Wind Chamber Vertical Axis Wind Turbines

The present invention relates to a vertical axis wind turbine, and more particularly to a vertical axis wind turbine with higher efficiency by improving the structure and shape.

In general, since the vertical axis wind turbine is less efficient than the horizontal axis wind turbine, research and development has not been actively conducted. However, in terms of physics, the existing horizontal axis wind turbines that generate horizontal wind force to lift and drag resistance to the vertical wing surface and convert it back to vertical rotational power have high energy loss due to frictional resistance such as drag force. It can be seen that the fall.

Specifically, the horizontal axis wind turbine currently widely used has a large energy loss rate due to the wind as described above, in order to obtain the required electrical energy, the length of the blade must be manufactured in the size of several tens of meters. In addition, the vertical wind pressure applied to each of the blades of several tens of meters in length generated a torsional pressure at the joint portion of the rotational axis with tremendous moment force. One wing fixing device is required, and the material of the wing also needs to be made of a special material. Therefore, the horizontal axis wind turbines currently in use are excessively expensive to manufacture the vanes, and the height and size of the steel cylindrical tower supporting the wind turbines are enormously increased to withstand the horizontal wind pressure applied to each vane. Inevitably, there is a problem in that an excessive installation cost and a considerable maintenance cost are required.

Therefore, it can be assumed that the vertical axis wind turbine, which is a device that uses the horizontally-generated wind turbine as a rotating force using horizontal rotating blades, can minimize energy loss and obtain higher efficiency. . However, the existing vertical shaft wind turbine currently being manufactured and used is significantly reduced efficiency, the problems are as follows.

First, the wind turbine has not solved the problem of reducing the frictional resistance to the blade portion that rotates as opposed to the wind when rotating. Specifically, conventional vertical wind turbines are designed to produce large frictional resistance due to wind pressure on the blades that rotate in the same direction as the wind, while using them as rotating energy. There was a problem that frictional resistance occurred. That is, the existing vertical axis wind turbine can generate a considerable amount of rotational energy in the same direction as the wind pressure, but the overall efficiency is not large due to the relationship that generates a loss energy equivalent to the rotational energy in the opposite direction to the wind pressure. Had a problem.

In addition, in order to increase the rotational force about the central axis, the greater the rotational force of the moment is applied to the central axis, the greater the rotational force can be obtained. However, the wing of the conventional vertical wind turbine has a short moment arm from the central rotational axis. It is a structure, which shows a limit of inefficiency.

Secondly, existing vertical wind turbines are usually small wind turbines, which are limited in their size and structure. Specifically, in terms of the structural aspect, the wing is a vertical surface in the form of a curved shape, which is limited to a certain extent in expanding the diameter and height of the wing. The problem is that designing a system is not easy. In addition, due to the relationship that the structure is difficult to make a structural reinforcement when the wing is large, high wind pressure may cause problems in the structural safety of the wing when rotating at high speed.

Third, existing large-scale vertical axis wind turbines are exposed to limitations in the selection of installation location, safety, and tower height due to their structural shape and operating principle. In general, a large vertical shaft wind turbine developed in the past is mostly a turbine blade is developed as a fixed vertical plane of the curved or flat surface form is supported by the outer steel cage. And to support the wind turbine is a form that is supported by a wider lower structure of the steel structure. Therefore, such a structure is not only exposing the problem in the location selection because of its large size, but also causes a structural problem in installing a high steel frame tower in order to be exposed to wind pressure of a suitable height.

Accordingly, the applicant of the present invention has been to find a vertical axis wind turbine having a simple structure and more efficient to solve the problems described above.

In addition, the vertical axis wind turbine according to the present invention in order to operate the wing opening and closing control device for controlling the opening and closing of the wing to the wind vane to operate the upper and lower wings and the outer wing of the turbine rotated by the wind most effectively. Regardless of which direction the wind vane and vane opening / closing controller controls the opening and closing of each vane in the wind turbine, the wind turbine always provides an efficient rotational energy.

In addition, the vertical axis wind turbine according to the present invention is designed in a three-dimensional truss structure to structurally and safely expand the blade size when the diameter of the turbine is expanded to obtain the required power energy, the turbine during the wind The wing opening and closing rail control hydraulic cylinder device is installed so that all the wings can be closed for a minimum.

Hereinafter, the present invention will be described with reference to FIGS. 1 to 14 as follows.

Vertical axis wind turbine according to the present invention is to open the wind energy in the horizontal direction generated by the wind in each of the wings attached to the satellite disk type turbine in the vertical and outer three directions to maximize the area of the blade, the upper and lower horizontal The wind friction resistance formed by the trapezoidal wing shape and the outer blades and the windscreens attached to each radial truss increases the rotational moment arm of the wing from the central rotational axis to increase the rotational force. Wind turbines enclosed by windshields attached to the inner truss supports form a maximum frictional resistance against the wind, converting it into rotational energy, and on the other hand the blades of the turbine rotating in the opposite direction of the wind To close the wind chambers and rotate them By minimizing the frictional resistance against the wind to minimize the loss of rotational energy, to provide a vertical axis wind turbine device that generates the most efficient rotational energy as a whole.

In general, when looking at the development of vertical axis wind turbines, turbine blades that rotate in the opposite direction to the direction of the wind are fixed blades, so there is a problem that the loss of rotational energy is lost because there is no solution to the air friction resistance. Due to the short relationship between the arms of the rotational moment of the blades, the vertical shaft wind turbine is known to be less efficient because the torque is weaker than the horizontal shaft wind turbine.

The vertical axis wind turbine according to the present invention is a wind turbine for converting the wind into the maximum efficient rotational energy by solving such problems, as shown in FIG. Forming the chamber and closing all the blades of the turbine rotating in the opposite direction to the wind is characterized by forming a wind chamber of negative pressure to minimize the frictional resistance of the air.

At this time, the outer shape of the closed wind chambers of the turbine rotating in the opposite direction to the wind direction is to receive a minimum of the frictional resistance of the air in order to make the outer shape of the outer wing (5) to have a curved surface, the upper and lower wings (3 , 4) is designed to have a minimum of wind friction resistance as it is wedge shape from the center axis to the outer end.

In addition, the rotational force obtained through the rotation of the upper and lower blades (3, 4) and the outer blade (5) is transmitted to the lower gearbox through the rotary power transmission shaft (8) in the center of the wind turbine, By operating the generator to control the number of revolutions to produce electrical energy.

As shown in FIG. 3, the vertical axis wind turbine according to the invention is attached to the upper and lower vanes 3 and 4 and the respective radial trusses in the direction in which the turbine rotates in the same direction as the wind direction in order to obtain maximum air frictional resistance. Designed to receive the largest frictional resistance of the air by increasing the wind resistance and outer wing (5) to the largest frictional resistance area due to wind pressure, in particular, the shape of the upper and lower blades (3, 4) of the turbine outside the central axis It is formed to be enlarged in a horizontal trapezoidal shape toward the end, and the outer wing 5 is mounted and opened to increase the magnitude of the moment arm and the force due to wind pressure from the central rotation shaft 8 to maximize the rotational force. It was designed to have a structure that can be obtained. That is, the vertical axis wind turbine according to the present invention is characterized in that the size of the rotation momentum from the central rotation shaft 8 is increased by forming the shapes of all the blades installed in the outer direction. On the other hand, as described above, if the technical object of the present invention can be achieved, the shape of the wing is not limited to an inverted triangle. In addition, the material of the upper and lower blades (3, 4) and the outer blade (5) of the vertical shaft wind turbine according to the present invention is to be made of a new carbon glass fiber reinforced plastic (GFRP) as a material that can reduce the weight and increase the strength.

As shown in FIG. 3, the vertical axis wind turbine according to the present invention allows the entire turbine structure to consist of a radial trapezoidal wedge truss structure 6 of a radial type about a central axis of rotation 8. That is, the vertical axis wind turbine according to the present invention allows the central structure to be formed of a radial trapezoidal wedge truss structure 6 of the radial type, thereby minimizing the area of the air frictional resistance of the turbine at the portion where the turbine rotates against the wind direction. It is not only a form that can effectively reduce the air frictional resistance, but also a structure that can expand the diameter of wind turbine more stably to obtain more power energy, and also widen the surface of the rotating rail and supporting structure of the radial turbine. The turbine can be stably maintained even in the strong lateral force caused by wind pressure. The material of the radial horizontal trapezoidal wedge truss structure 6 and the outer ring 7 disclosed in one embodiment according to the invention is made of aluminum-based metal to reduce the weight of the turbine.

Figure 4 discloses a wing opening and closing adjustment device (2) for adjusting the opening and closing of the upper and lower wings (3, 4) and the outer wing (5) of the vertical axis wind turbine according to the present invention, the wind vane (1) and wing opening and closing adjustment The rail 9 and the hydraulic device for adjusting the height of the rail are integrally configured.

The vertical axis wind turbine according to the present invention is formed to change the position of the wing opening and closing adjustment rail 9 formed integrally therewith as the position of the wind vane 1 changes according to the wind direction. In addition, the entire wing opening and closing adjustment rail 9 is formed by separating the wing opening section, the inclined ramp section and the closing section. Specifically, in one embodiment of the present invention, the right section of the wing opening and closing control rail 9 is always an open section, and the left section is formed as a closed section around the front wind direction.

Figure 5 shows a cross-section of the rail of the wing opening section of the wing opening and closing adjustment rail 9 of the vertical shaft wind turbine according to the present invention, looking specifically at the configuration with reference to the drawings, the end of the upper blade (3) The wing opening and closing roller bar 12 provided in the upper portion is formed to rise upwards, and in this case, the upper and lower wings 3 and 4 and the outer wings 5 are shown to open the situation. 6 shows the inclined ramp section. When the wing opening / closing roller bar 12 formed at the end of the upper blade 3 passes through the rail slope section 11, the upper and lower blades 3 and 4 and the outer wing thereof are shown. (5) is gradually closed, Figure 7 shows the rail closed section, when the blade opening and closing roller bar 12 passes through the closed rail section, the upper and lower wings (3, 4) and the outer wing (5) is closed and rotates. When strong wind pressure is applied to the turbine due to strong wind or typhoon, the height of the open / close section of the wing opening / closing control rail 9 is adjusted by the hydraulic control device mounted on the upper part of the wing opening / closing adjustment rail 9, and the upper and lower wings 3, 4) and the open angle of the outer blade (5) was adjusted to rotate the turbine. As described above, the vertical shaft wind turbine according to the present invention allows to adjust the position of the wing opening and closing rail 9, and at the same time using the kinematic principle, the upper and lower blades (3, 4) of the vertical shaft wind turbine according to the present invention; It is characterized in that the opening and closing of the outer blade 5 can be automatically adjusted, and the wing opening and closing rail 9 according to the present invention automatically adjusts its position according to the movement of the wind vane 1. It is formed so as to enable a smooth opening and closing operation of the blade.

Looking at the configuration of the vertical shaft wind turbine according to the invention with reference to Figure 8, the anti-rotation gear device 16 of the vertical shaft wind turbine according to the present invention is the wing opening and closing adjustment device 2 when the wind turbine rotates the upper blade ( 3) The wing opening and closing roller bar 12 installed at the end is formed to prevent the rotation of the wind turbine in the direction of rotation of the wind turbine by the frictional force with the wing opening and closing adjustment rail 9, and also the rotation of the wind turbine It is formed to enable rotation of the wing opening / closing adjustment device 2 with respect to the wind direction (left direction in the figure) blowing in the opposite direction.

The position of the wing opening and closing adjustment device 2 according to the present invention is always configured to move in accordance with the position of the wind vane 1, in order to enable such an operation to increase the area of the wind vane 1 vane sufficiently large wind vane (1) The wing open / close adjustment device 2 always opens and closes the blade regardless of the rotation of the vertical shaft wind turbine by allowing the wind vane 1 to always receive the wind resistance so that the wind vane 1 always maintains its position in the wind direction. To do this. On the other hand, the anti-rotation gear 16 is fixed to the center fixed shaft 10 is formed so as to be movable only up and down.

At this time, the anti-rotation safety pin 17 is released by lifting the anti-rotation gear drive ring 18 associated with the anti-rotation gear release driving shaft 19 upward by a spaced height, thereby releasing the anti-rotation safety pin 17. An integrated wing opening and closing adjustment device 2 is rotated in the direction of the wind direction, and thus the wing of the wind turbine is operated to open and close according to the changed wind direction. For reference, the rotary drive gear 20 is divided up and down and the upper rotary drive gear is movable left and right and up and down, the lower rotary drive gear is fixed to the center fixed shaft 10 is formed to be rotated only left and right.
