Embodiment Construction

[0043] The present invention will be further elaborated and described below in conjunction with the drawings and specific embodiments.

[0044] Such as figure 1 As shown, a schematic diagram of the overall structure of a bladeless wind power generation device in a preferred embodiment of the present invention is shown. To facilitate the understanding of the structure diagram, Figure 2-Figure 9 Shows a schematic diagram of each part. In this power generation device, there is a hollow thin-walled tube 1 in the shape of an inverted truncated cone. The diameter of the hollow thin-walled tube 1 gradually increases from bottom to top, and the cross section is a regular circular shape, so that it can accept any direction Wind load, and the hollow thin-walled tube can greatly increase the diameter of the windward surface and reduce the height of the overall device. The connecting rod 3 is arranged coaxially with the hollow thin-walled tube 1 and one end partially extends into the inner...

Abstract

The invention discloses a blade-free wind power generation device based on a vortex vibration theory and an electromagnetic induction theory. The blade-free wind power generation device comprises a hollow thin-wall cylinder, wherein the hollow thin-wall cylinder is in an inverted circular truncated cone shape. The hollow thin-wall cylinder is installed on a connecting rod through a fixing device,the hollow thin-wall cylinder and the connecting rod are installed in an erected mode, and the bottom of the connecting rod is fixed to a foundation. A permanent magnet which synchronously swings along with the connecting rod sleeves the connecting rod located at the bottom of the hollow thin-wall cylinder. A plurality of closed electromagnetic induction coils are laid outside the permanent magnet, and when the permanent magnet synchronously swings along with the connecting rod, magnetic induction lines of the permanent magnet alternately cut the electromagnetic induction coils to generate thecurrent. By the adoption of the blade-free wind power generation device based on the vortex vibration theory and the electromagnetic induction theory, no conventional fan blades are required, a magnetic field is generated by the use of vortex vibration to conduct cutting, and then electric energy is formed; and the wind load in any wind direction can be received, and the situation that an additional device is needed to guide the wind direction so as to obtain the maximum wind energy is not required.

Description

Technical field [0001] The invention relates to a bladeless wind power generation device based on the principles of eddy current vibration and electromagnetic induction, and belongs to the field of renewable energy wind power generation. Background technique [0002] As a kind of renewable green energy, the reasonable development and utilization of wind energy can effectively alleviate the current energy shortage and the pollution caused by fuel materials to the environment, which has been highly valued by all countries. As of 2014, the cumulative global installed wind power capacity has increased to 425 GW year by year, and according to estimates, the cumulative global installed wind power capacity will increase to 8.5 TW by 2050. In China, the installed capacity of wind power has developed rapidly since 2006. As of 2010, the cumulative installed capacity of wind power reached 45GW. [0003] At present, the most important fan principle is to use wind to drive the fan blades to ro...
