Description

Vertical wind power generator with dust collector {vertical wind power generator for using concentration device}

The present invention relates to a vertical axial wind power generator that is generated by using wind, as well as to eliminate the resistance that interferes with the rotation of the blade as well as to improve the efficiency by changing the flow of air and can be applied to flowing water.

In recent years, wind power has become one of the most prominent renewable energy sources, and it is rapidly spreading not only in Europe but also in the US and China. Wind power generation is divided into vertical axis and horizontal axis, and vertical axis wind power generation is representative of Savonius type using drag and Darius type using lift.

     Patent No. 10-0927237 has good idea, but it does not help greatly in improving efficiency for cost, and Patent No. 10-0916701 is far from improving efficiency, and Patent No. 10-0895038 is somewhat inefficient in terms of cost effective dust collector. There is a side.

     Patent registration 10-0810990 has a dust collector, but the power generation is proportional to the cube, not the square of the wind speed, so the low point from the ground is much lower wind speed, so the efficiency is lower as the tower is lower. Patent No. 10-0490683 claims to produce efficient power by adjusting the pitch angle, but the efficiency is not much improved.

     Although efforts are being made to concentrate the wind and improve the part that hinders the rotation of the blade, there is a problem that the cost-effectiveness improvement effect, which is a chronic problem of vertical shaft wind power generation, is insignificant.

     In order to solve the above problems, the blade is composed of the inner shell and the outer shell to form a structure that separates and combines automatically with each other, dramatically reducing the resistance acting in the opposite direction of the blade rotation and both lift and drag In addition to improving power generation efficiency, the fluid induction plate using a tension spring was used to speed up the flow of fluid such as wind to rotate the rotor blades faster to produce more power. In addition, by using high tower, strong wind can be used and vertical axis wind power generation using drag and lift simultaneously maximizes efficiency.

     As described above, the present invention, the blade is composed of the inner shell of the wind resistance and the outer shell little resistance, significantly reducing the resistance of the parts that do not need to rotate significantly improved the efficiency of the vertical axis wind power generation. In addition, it can be applied in both water and air, and is equipped with a dust collecting device using a tension spring for higher efficiency. This dust collector is excellent for using Savonius-type blades that use drag, and it can replace the present invention where safety problems or noise are so high that it is impossible to install horizontal axial wind power generation. It is possible to generate power even in impossible skyscrapers, and it is possible to compete with horizontal wind farms by enabling vertical wind farms in the large wind power market.

      The present invention is intended to remove the drag hindered rotation and to use the strong wind by collecting the wind using a dust collector, for example, wind blowing during the day at a speed of 22m per second more than the wind blowing all year round at a speed of 3m per second Since it has a lot of energy, the gathering of fluids such as wind is important, so the present invention is more valuable.

     As described above, the present invention is equipped with a dust collector that can not be installed in a horizontal shaft wind power generation with an efficiency of about 15-20%, and can generate power with high efficiency of 120-130%. The invention will greatly contribute to the growth of new and renewable energy industry in wind power as well as large wind power generation.

     When described in detail by the accompanying drawings as follows and will be described mainly in the wind energy.

     1 is a perspective view of an improved blade, in which the blades d, e, f gain wind and power to rotate, but a, b, c are rather obstructed to rotate, this resistance In order to reduce the maximum, the blade inner shell 13 and the blade outer shell 14 is a structure that is automatically separated and combined under the wind.

     The blade holder 12 is vertically connected to the main shaft 15, and the blade 11 composed of the blade inner shell 13 and the blade shell 14 has an angle of s in the figure in the direction of rotation to the blade holder 12. It is fixed at 120 ~ 140 degrees and each blade is winded and turned counterclockwise.

     The blades are convex in the direction of rotation to apply Bernoulli's principle, which is the same as the principle of ascension of the plane, and the curved part flows quickly and the fluid flows quickly, which means that the pressure of fluid such as air is weak. This is the principle that the object moves toward the weaker pressure. In this figure, blade d is lift, blade e is drag, and blade f is lift.

     FIG. 2 shows the opening and closing state of the blades when the wind is constantly blown. Blades d, e, and f which are acting in the wind are combined with the blade inner shell 13 and the blade outer shell 14, but a, b, and c are combined. The blade endothelium 13 and the blade shell 14 are separated from each other to minimize the wind resistance, which is the curved portion of the blade shell 14, q portion is partly blocked to hold the blade endothelium 13 but is straight The p part is open, and when the wind that touches the blade is changed due to rotation, the blade endothelium (13) is naturally out like the blade c. In addition, when it comes to the position of the blade a while rotating, it tries to merge naturally, and when it comes to the position of the blade d, it is completely combined to receive the wind and perform the rotation.

      Figure 3 is a detailed view of the blade, Figure 3-a is a front view of the blade and the endothelial and the outer shell is combined, the blade endothelial guard 31 prevents the blade endothelial 13 from being pushed, Figure 3-b is a blade It is easy to understand the shape of the blade 11 as a perspective view in which the inner shell 13 and the blade outer shell 14 are separated.

      FIG. 3-c is a plan view of the blade shell 13 and the blade shell 14 separated. As shown in FIG. 3-a, the blade shell 14 has almost no function and is an asymmetric structure. The purpose is to play a supporting role, but in order to prevent the detachment of the blade endothelium 13, the two safety rings 132 at the top and bottom to connect with the outer shell for safety and additional safety measures can be taken if necessary. .

      Figure 4 is an analysis showing the reaction and the reaction against the wind, the deflection, the hatched portion when the blade is rotated in the counterclockwise direction after the improvement is not a big difference in obtaining the rotational force to the wind, The abc, which is a mesh display, had a reaction against the wind before it was improved, but after the improvement, the blade inner shell (13) and the blade outer shell (14) were separated. Shows what happened.

      Blade c has a larger resistance than ab, so its efficiency is lower, so k is larger than g or h, and net b is actually more effective, so it needs to be wider, but there is no room for d due to d acting on rotation. It is small and shows that the improvement is more than the sum of abc.

      5 is a cross-sectional view when the dust collector is attached, and the two fluid guide plates 52 are attached to collect the wind to increase the area where the blade 11 touches the wind, as well as to make the wind stronger, thereby increasing the rotational force. . The fluid guide plates 52a and 52b are primarily supported by the fluid guide plate holder 53 and finally supported by the dust collector upper support 55 and the dust collector lower support 56. The tension spring 54 is operated when the wind blows more than a certain speed to make the fluid guide plate 52 be in line with the wind, and to stop the original function of the fluid guide plate 52 and prevent the wind from being resisted. In the figure, the main shaft 15 had to be drawn long, but only the circles above and below were omitted because the drawings became complicated and the identification became unclear.

     The fluid guide plate 52a also affects the blade e, but directly affects the blade d and exerts a rotational force. The blade d also receives a naturally blowing wind at the same time, which makes the driving force much stronger. In addition, the fluid guide plate 52a serves to remove the resistance to the blades a and b by changing the wind direction at a predetermined speed or less, thereby increasing the rotational force of the rotor.

     The fluid guide plate 52b has a weak effect on the blade e, but also directly affects the blade f, which has little rotational force in the natural wind, thereby increasing the rotational force. After the fluid guide plate 52 is installed, blade d is lift, blade e is drag, and blade f is lift. However, after installation, blade d is lift and drag, and most blade e is drag and blade. f is the lift force and drag force are applied at the same time to increase the torque. The blades a and b can avoid direct wind resistance due to the fluid guide plate 52a, and the dust collector can be effectively applied to Savonius wind power generation, a typical vertical axial wind power generation using drag.

     Fig. 6 is a plan view when the dust collecting device is attached, and is a plan view of the blade on which the dust collecting device is attached. A dust collecting device having two fluid guide plates 52 is mounted above and below the main shaft 15 by using a fluid guide plate holder 53, an upper support 55, and a lower support 56 in FIG. 10 above and below the blades. (63) and the bearing connecting ring 62 and attached to the tail wing 51, which is a plate perpendicular to the ground at the opposite end of the upper support 55 to prevent the fluid guide plate 52 to rotate.

It is better to design the fluid guide plate 52a to be larger than the fluid guide plate 52b to achieve the force balance, and the tension spring 54 is about one quarter from the bottom of the fluid guide plate 52 and four quarters from the top. If installed at each one point, the fluid induction plate 52 due to the wind and the like can be reduced to a large part of the bending due to the opposite of the bending force. When a strong wind of more than a certain wind is blown, that is, when a strong wind of 15-20 m / s or more is blown, the dotted line in which the fluid guide plate 52 coincides with the direction of the wind . And me. The strength of the tension spring 54 is designed differently so as to come to the position of.

     FIG. 7 is a plan view of another method when the dust collector is attached, in which the fluid guide plate holder 53 is directly connected to the bearing connecting ring 62, and a blade equipped with a dust collector of a method slightly different from that of FIG. It is a plan view from above, and the bearing connecting ring 62 is not overly stressed and more stable, which may be more practical than the method of FIG. 6.

Two pairs of tension springs 54 should go above and below the blade, or else the dust collector upper support 55 and the dust collector lower support 56 will be further dotted . As such, the blades may not be in contact with each other so that they can be installed at about one quarter from the bottom of the fluid induction plate 52 and one quarter from the top. It may be practical as less is needed.

Also, the dotted line between each fluid guide plate holder 53a and 53b . like If the spring is fixed by connecting a wire or the like, the upper support 55b is not necessary, and if it is the same below, the lower support 56 paired at the bottom is also unnecessary. The fluid guide plate guide 53 may be formed in a U-shape like the fluid guide plate guide 53c indicated by a dotted line without being directly connected to the bearing connecting ring 62, but it does not seem to mean much.

      FIG. 8 is an analysis diagram showing the action against the wind after the dust collector is attached. In the absence of the dust collector, the hatched portion def gains rotational force due to the action against the wind. Wind is collected at d and f respectively, increasing the rotational force by the area n and m of the brick pattern, and the flow velocity is increased by the effect of the dust collection, and the rotational force may be increased by the star-shaped area o. This means that the efficiency is improved by the added nmo than in Fig. 4, which is generally 15-20% efficient on the horizontal axis and 15-60% on the vertical axis, but 120-130% efficient with the present invention. Can make

     FIG. 9 is a detailed view of the fluid guide plate 52. FIG. 9-A shows that the fluid guide plate 52 becomes narrower in the direction in which the fluid flows. The length of a is smaller than that of b, so that the effect of collecting air is greater, and FIG. 9-b shows a bent end to increase efficiency by preventing air from immediately exiting.

     10 is a side view of a blade equipped with a dust collector, in which only one fluid guide plate 52 supported by the upper support 55 and the lower support 56 is drawn and the auxiliary support 101 in consideration of the weight of the dust collector. You can also install). Here, the role of the tail wing 51 is very important. Even if the two fluid guide plates 52 are designed to balance each other, it cannot be perfect. Therefore, the tail wing has to keep the wind in a straight line to give the maximum dust collection effect. Tail wing 51 should be strong and large enough. Although the fluid guide plate 52 is made to rotate naturally, the guide plate safety device 103 is installed as a double safety device. The left part is the guide plate safety device 103 in an enlarged view of the right circle.

     FIG. 11 is a schematic cross-sectional view of a tower equipped with a speed increaser and a generator. In general, vertical shaft wind power generation uses a gearless generator that does not require a speed increaser when the speed increaser and the generator are installed on the ground or in the case of a tower type. It is possible to build a tower corresponding to the power generation, this picture corresponds to the lower part of Figure 10 will be connected to each other to generate power.

     The main shaft 15, which transmits the rotational force of the blades, passes through two bearings 63 supported by the bearing support 115 connected to the tower 116 and is connected to the speed increaser 111. 113) and the stator 114 shows a structure to generate power by increasing the rotational speed of the generator 112. The tower 116 of the section with the gearbox and the generator is convex, and in the case of large power generation, the tower of the section with the gearbox 111 and the generator 112 has a large number of doors on the strong arm of the mesh, It will be easy to troubleshoot shorthand.
