Embodiment 1

[0022] Embodiment 1, the present invention includes a conical wind tower 1, a connection plate 2, a permanent magnet upper plate 3, a permanent magnet plate 4, a connection support 9, an energy conversion device 8, a speed increaser 5, a generator 6 and a support 7; One end of the conical wind tower 1 is fixedly connected to the connection plate 2, and the connection plate 2 is connected to the permanent magnet upper plate 3 on the connection plate 2 to form a whole. The support 7 is provided with a generator 6, a speed increaser 5 One end is connected to the generator 6, and the other end is connected to the energy conversion device 8. The permanent magnet disk 4 is arranged on the energy conversion device 8. The permanent magnet upper disk 3 is connected with the permanent magnet disk 4 through a connection support 9, and the permanent magnet is connected to the permanent magnet disk 4. The magnetic poles on the opposite sides of the disk 3 and the permanent magnet disk 4 rep...

Embodiment 2

[0023] Embodiment 2, the conical wind tower 1 of the present invention, the connecting support 9 and the energy conversion device 8 are connected together to form a whole; when the wind acts on the conical wind tower 1, due to the Karman vortex street principle, the conical wind will The tower 1 generates a periodic alternating lateral force, which causes the conical wind tower 1 to generate periodic vibrations. The vibration frequency and amplitude obtained by the conical wind tower 1 are transmitted to the energy conversion device 8 through the connecting support 9, thereby realizing the conical wind tower 1. The transmission and transformation of the wind energy obtained by the wind tower 1. refer to figure 1 , all the other are with embodiment 1.

Embodiment 3

[0024] Embodiment 3, the permanent magnet upper disk 3 of the present invention is fixed on the connection disk 2, the permanent magnet disk 4 is fixed on the outer end of the energy conversion device 8, the relative planes of the permanent magnet upper disk 3 and the permanent magnet disk 4 are kept parallel, and The magnetic poles on the opposite planes of the permanent magnet upper disk 3 and the permanent magnet disk 4 repel each other; when the conical wind tower 1 deflects under the action of the wind, the permanent magnet upper disk 3 also deflects correspondingly, while the permanent magnet disk 4 remains unchanged. Therefore, the relative planes of the permanent magnet upper disk 3 and the permanent magnet disk 4 are no longer kept parallel, and the repulsive force generated by the short side will be greater than that of the long distance, forcing the permanent magnet upper disk 3 to return to the permanent magnet disk. 4, thereby driving the conical wind tower 1 to sw...

Abstract

The invention discloses a bladeless wind driven generator. The bladeless wind driven generator mainly solves the technical problems of influences and the like caused by using blades in an existing wind driven generator. According to the technical scheme, the bladeless wind driven generator is characterized by comprising a conical wind tower (1), a connecting plate (2), a permanent magnet upper plate (3), a permanent magnet plate (4), a connecting support (9), an energy conversion device (8), a speed increasing device (5), a power generator (6) and a support (7). One end of the conical wind tower (1) is fixedly connected with the connecting plate (2). A whole is formed by connecting the connecting plate (2) and the permanent magnet upper plate (3) on the connecting plate (2). The generator (6) is arranged on the support (7). One end of the speed increasing device (5) is connected with the generator (6), and the other end of the speed increasing device (5) is connected with the energy conversion device (8). The energy conversion device (8) is connected with the conical wind tower (1) through the connecting support (9). The bladeless wind driven generator is simple in structure, convenient to manufacture and maintain, low in manufacturing cost, free of noise, capable of protecting the natural ecological environment and the like.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, in particular to a wind power generator without blades. Background technique [0002] Wind energy is a renewable, non-polluting natural energy with huge reserves, which has been highly valued by countries all over the world. For example, from 2002 to 2015, the global installed capacity of wind power has grown from 17.4GW to 432.9GW, an increase of about 23 times. The basic principle of wind power generation is to use the wind to drive the wind rotor blades to rotate, and then increase the speed of rotation through the speed increaser, and then promote the generator to generate electricity. [0003] The devices required for wind power generation are called wind turbines, which mainly include wind rotors, generators, iron towers, and tail rudders. The blades of the horizontal axis wind turbine generally have 2-4 pieces, and as the output power of the wind turbine increases, the size ...
