Description

A magnetic levitation variable speed wind generator

Technical field:

The utility model relates to the field of motors, in particular to a magnetic levitation variable speed wind power generator.

Background technique:

A wind turbine is a power machine that converts wind energy into mechanical energy and mechanical energy into electrical energy, also known as a windmill. Broadly speaking, it is a thermal energy utilization engine that uses the sun as the heat source and the atmosphere as the working medium. For many centuries, wind generators, like hydraulic machinery, have been used as power sources to replace human and animal power, and have played an important role in the development of productivity. As the main component of the generator, its performance will greatly affect the power generation efficiency and service life of the overall generator. In order to improve the power generation efficiency, many wind power generators currently use magnetic levitation generators, and magnetic levitation bearings are installed in them. Compared with traditional rolling and sliding bearings, magnetic bearings are characterized by no mechanical contact, no force transmission medium, and controllable support, so they have superior performance that traditional bearings cannot match. Magnetic bearings can be divided into three types: active magnetic bearings, passive magnetic bearings and hybrid magnetic bearings. So far, the main research object is active magnetic bearings, which is due to the high controllability and relatively small volume of active magnetic bearings. However, for some wind turbines in special applications, especially in the case of continuous power generation and energy supply, once the wind force becomes too small to drive the shaft to rotate, the power generation and energy supply will be interrupted , thus affecting the use of actual equipment.

detailed description:

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in detail:

As shown in Figure 1 and Figure 2, a magnetic levitation variable speed wind generator is shown, which is applied to equipment that requires continuous energy supply and where the wind speed changes greatly. It includes a bottom support base 1 and is fixedly installed on the bottom support base 1 On the magnetic levitation generator body 2, a passive gear 3 is fixedly connected to the rotating shaft end of the magnetic levitation generator body 2, and a driving shaft 4 parallel to the rotating shaft is fixedly installed on the side of the magnetic levitation generator body 2, so One end of the driving shaft 4 is fixedly equipped with fan blades 5, and the other end of the driving shaft 4 is provided with at least three driving gears 6 with successively decreasing diameters. The driven gear 3 and the driving gear 6 There is a connecting piece 7 for transmission connection between the two. Above the connecting piece 7, there is a toggle device that can toggle the connecting piece 7 back and forth.

As a preferred embodiment, in order to make the transmission effect between the passive gear and the driving gear better, the connecting member 7 is set as a chain, and the chain transmission connection between the passive gear 3 and the driving gear 6 can maintain better The transmission connection can maintain good stability.

However, in practical applications, in order to facilitate the fast and convenient switching of the connecting piece between the driving gears, as shown in Figures 2 and 3, the toggle device includes hollow support rods 8 placed on both sides of the connecting piece 7 And the horizontal cross bar 9 between the hollow support rods 8, a long groove-shaped slide rail is provided on the lower side of the horizontal cross bar 9, and a dial ring that can slide freely back and forth on the slide rail is provided 10. There are two traction ropes 11 attached to the dial ring 10 that can pull and slide it back and forth, and the two traction ropes 11 respectively pass through the inner cavity of the hollow support rod 8 on both sides and surround the hollow support rod 8. On the winding disk 12 at the bottom, as a preferred embodiment, the traction rope 11 is set as a soft steel wire rope, thus ensuring sufficient strength and toughness. In the process, it is only necessary to control the operation of the miniature deceleration motor according to the needs, and then drive the winding disc to rotate and make the front and rear traction rings of the traction rope 11 slide freely on the horizontal bar, and then drive the chain to switch back and forth between different driving gears, so as to keep the motor shaft Different speed ratios to the fan blade shaft.
