Coaxial asynchronous dual-drive vortex turbine

Abstract

The invention provides a coaxial asynchronous dual-drive vortex turbine which comprises a frame (7), a main shaft (3) and rotatable blades (4). The main shaft (3) is vertically arranged in the middleof the frame (7) and is positioned on an input end of an electric generator; the rotatable blades (4) are arranged on the outer edge of the main shaft (3) in the circumferential direction; and blade rotating shafts (6) are hinged to the frame (7). The coaxial asynchronous dual-drive vortex turbine adopts the technical key points that when the frame (7) rotates, a blade main body is always positioned in the frame (7), a polygonal circumscribed circle formed by connecting lines between the blade rotating shafts (6) takes the shape of a perfect circle, the circle center of the perfect circle is positioned on a center shaft of the main shaft (3), and vertical stop levers (9) used for limiting the blades (4) to rotate are arranged on the connecting lines between the adjacent blade rotating shafts (6). The coaxial asynchronous dual-drive vortex turbine has the advantages of simple and compact structure, low cost, high energy conversion efficiency and the like.

Description

technical field [0001] The present invention relates to the field of generators, in particular to a hydraulic engine or a wind engine, specifically a coaxial asynchronous double-drive vortex turbine, and the IPC classification number involved is F03B or F03D. Background technique [0002] Human beings have used wind energy and water flow energy for a long time, such as waterwheels and the famous Dutch windmills. Today, ocean current power generation and wind power generation are basically improved by referring to the principles of Dutch windmills. Using this method is currently the most ideal and effective The maximum conversion power can only be 0.26. If all the kinetic energy of wind or water is absorbed by the blades, the air pressure behind the blades and the air in front will form a confrontational situation, just like a group of people entering a revolving door. The people who have just passed are exhausted and cannot Keep going (the wind converts 100% kinetic energy t...

Problems solved by technology

[0003] However, this kind of wind turbine does not solve the problem of energy conversion and medium flow of blades. The source of energy is the speed of fluid flow. When the fluid speed is absorbed by the blades and converted into mechanical energy, the carrier such as: (air, water) still exists, according to the material The indestructible theorem, no matter what kind of carrier is used, when the fluid speed is absorbed by the blade and transformed into mechanical energy, the speed is absorbed, but the carrier still exists, if there is no place to go, resistance will be formed, there will be no new speed, no new The speed will lose the mechanical energy brought by the rotation. How to deal with these carriers without speed is the key to technological breakthroughs. It requires both speed and the removal of these carrier media that have lost speed. It can be seen that in the carrier The energy brought by the high-speed fluid medium is continuously absorbed without affecting the subsequent energy entry, which is the most ideal wind turbine

[0004] For example, a water turbine disclosed in the application publication number CN 107044375 A and a hydroelectric power generation device with the water turbine, in this technical solution, when the central axis of the central rotating assembly 3 is deflected, the connecting assembly 4 connected to the central rotating assembly 3 is in the When rotating, it will cause balance problems, increase the resistance of the output shaft, and reduce the energy efficiency conversion rate; since the connecting assembly 4 is located on the fluid path, the connecting rod 41 of the connecting assembly 4 is too thin to support the weight of the blade 53, and the connecting rod 41 is set. If it is too thick, it will increase the overall resistance of the system, so this solution has obvious defects
