Description

Technical Field

[0001] This invention relates to a wind and water turbine blade device that does not break even in storms or floods and can increase the wind speed and river flow velocity.

Background Art

[0002] Conventional large propeller blades can break during storms, and screw blades installed in rivers can bend even when only in contact with floating logs during floods. Also, the flow velocity of wind turbines and water wheels in rivers could not be increased.

Summary of the Invention

Problems to be Solved by the Invention

[0003] Therefore, an object of this invention is to prevent the wind and water turbine blades from breaking even in storms or floods and to increase the flow velocity hitting the blades.

Means for Solving the Problems

[0004] To solve the above problems, this invention joins a V-shaped right plate 1 and a V-shaped left plate 2 of an isosceles triangle isosceles part on the front side of the flow, and on the rear side of the flow, joins an upper plate 4, a lower plate 5, a Y-shaped right plate 6, and a Y-shaped left plate 7 for installing a rear cavity 3, and makes the front V-shaped opening width and the rear Y-shaped opening width of the flow the same width. Then, frame bars 8 are joined to the upper and lower parts of the V-shaped and Y-shaped openings, and a right stever 9 and a left stever 10 for adjusting the balance of the right-left rotation axis of the wind direction indicator for use during windmill operation are joined between the upper part, the upper and lower central parts, and the lower part of the frame bar 8. Identical multi-stage donut-shaped discs 11 arranged vertically are placed in the right-left outer sides of the right stever 9 and left stever 10 of the space installation and in the space part of the front and rear frame bars 8, and an inner cylindrical plate 12 that can be joined to the inner circle of the identical multi-stage donut-shaped discs 11 is installed and joined to join them. Then, a connecting and fixing bar 13 is installed toward the center of the inner cylindrical plate 12, joined to a rotating shaft 14 that rotates right and left, and a bearing receiving frame bar 15 for fixing the rotating shaft 14 is arranged and joined in the front-rear direction at the end of the frame bar 8. Then, a blade plate 16 is installed and joined between the rotating inner cylindrical plate 12 and the multi-stage donut-shaped disc 11 of the same shape in the bearing fixing of the bearing receiving frame bar 15. The installation angle of the blade plate 16 from the centrifugal direction is made to coincide with the angle of the V-shaped right plate 1 in the multi-stage donut-shaped disc 11 of the same shape on the right side, and the installation angle of the blade plate 16 in the multi-stage donut-shaped disc 11 of the same shape on the left side is made to coincide with the angle of the V-shaped left plate 2.

Advantages of the Invention

[0005] The windmill blades of this invention have the V-shaped right plate 1 and V-shaped left plate 2 of the isosceles part of the isosceles triangle on the front side of the flow, pushing the flow to the right and left, and the amount of wind corresponding to that flow rate flows into the blade plate 16 in the multi-stage donut-shaped disc 11 of the same shape, enabling speed increase.

[0006] Due to the presence of the right stay bar 9 and left stay bar 10 installed in the space in the structural frame of the windmill blades of this invention, the use of a wind-direction windmill becomes possible due to the existence of space for adjusting the balance of the installation of the front-rear rotating shaft during windmill operation. Also, if the length of the rear part of the Y shape of the upper plate 4 and lower plate 5 joined to the Y-shaped right plate 6 and Y-shaped left plate 7 is set to a length that generates a vertical fin effect, it can be self-sufficient in coping with changes in wind direction.

[0007] If a bridge girder is placed on the upper part of the Y-shaped part in the joining of the upper plate 4, lower plate 5, Y-shaped right plate 6, and Y-shaped left plate 7 of the windmill blades of this invention and used as a pier, it can be used as the waterwheel blades for the water in the river.

[0008] The joint part of the blade plate 16 of the windmill blades of this invention has a single-bucket structure in the joint structure between the inner cylindrical plate 12 and the multi-stage donut-shaped disc 11 of the same shape, and since the size of the single bucket can be made small, it is possible to create blades that do not break even in strong winds and floods.

Embodiment for Carrying Out the Invention

[0010] In this embodiment of the invention, the blade plate 16 is composed of an inner cylindrical plate 12 and an identical multi - stage donut - shaped disc 11, forming a structure that can achieve high strength in the production of a miniaturized bucket. It is arranged on the right and left, and is joined to the rotating shaft 14 by the connecting and fixing bar 13 and fixed to the rotating shaft 14 by the bearing - receiving frame bar 15. In front of and behind the identical multi - stage donut - shaped disc 11, through the frame bars 8 located front - rear and up - down, the V - shaped right plate 1 and V - shaped left plate 2 are used in the front to divide the flow rate to the right and left, increasing the flow rate hitting the blade plates 16 located on the right and left, thereby increasing the wind speed and river flow velocity. Also, in the rear, due to the existence of the rear cavity 3 for maintaining the long width, by joining the upper plate 4, lower plate 5, Y - shaped right plate 6, and Y - shaped left plate 7, a vertical fin effect is generated while maintaining the rear length, and due to the existence of the right stever 9 and left stever 10 at the central position of the identical multi - stage donut - shaped discs 11 on the right and left, a space is reserved for adjusting the balance of the installation of the front - rear rotating shaft during the operation of the windmill, forming a self - standing wind - direction adjustable windmill form. If the upper plate 4, lower plate 5, Y - shaped right plate 6, and Y - shaped left plate 7 parts are used as piers, a waterwheel form in the river can be achieved.
