Disclosure of Invention
Aiming at the problems, the invention provides a three-layer vertical axis double-channel wind driven generator which is used for solving the problems of low wind energy utilization rate, low generated energy, large starting resistance and difficult large-area popularization of the vertical axis wind driven generator in the current market.
In order to achieve the above purpose, the invention adopts the following technical scheme:
a three-layer vertical axis double-channel wind driven generator comprises a main power generation assembly and a secondary power generation assembly; the main power generation assembly comprises an inner coil frame, a magnet frame and an outer coil frame which are coaxially arranged on the main shaft and can rotate relatively; the inner coil rack is sleeved in the magnet rack; the magnet frame is sleeved in the outer coil frame; the outer coil frame is driven to rotate by a main fan blade on the outer wall; the outer coil frame drives the magnet frame to rotate through the first magnetic gear transmission assembly;
the auxiliary power generation assemblies are arranged at two ends of the main power generation assembly; the auxiliary power generation assembly comprises a rotating frame rotatably arranged on the main shaft; the rotating frame is driven to rotate by an auxiliary fan blade on the outer wall; the rotating frame drives the outer coil frame to rotate through a second magnetic gear transmission assembly.
Compared with the prior art, the invention has the beneficial effects that:
1. the channels are increased, so that coil windings are arranged on two sides of the permanent magnet poles of the magnet frame, the permanent magnet resources are fully utilized, the winding length is increased by nearly one time compared with that of the original single winding, and the power generation efficiency of the vertical axis wind turbine is obviously improved.
2. The outer layer coil accelerates the middle permanent magnet layer through the magnetic gear to form a differential speed, such as: when the outer layer rotating speed is 100rpm and the magnetic gear transmission ratio is 1:3, the speed of the middle permanent magnet is 300rpm, the speed of the outer layer coil cutting magnetic force lines is 400rpm, and the inner layer coil is static, so that the speed of the cutting magnetic force lines is 300rpm, namely the rotating speed of the middle layer permanent magnet, and therefore the magnetic force line cutting speed and the generating efficiency are remarkably improved through relative rotation.
3. Auxiliary starting is carried out, and the rotating speed of the main fan blade is continuously kept. The tip speed ratio of a general lift type blade is high, but the starting is difficult, and the lift type blade and a resistance type blade are directly connected in the market, so that the starting problem is only solved, but after the speed of the blade is up, the further lifting of the speed of the main blade is seriously hindered, and the efficiency of the whole machine is influenced. The resistance type blade drives the lift type main blade through the magnetic gear, the speed ratio of the general resistance type blade tip is below 0.9, the speed ratio of the lift type blade tip can reach about 4, the transmission ratio is set to be about 1:4, and the resistance type blade can bring continuous power to the main blade during operation (the actual wind resistance and the stable operation are considered to be about 1:2).
4. When the rotating speed exceeds a certain value, the brake block moves outwards to be in contact with the brake disc, so that the running speed of the blades is reduced, and the damage to the generator due to overlarge current caused by overlarge speed is avoided. When the speed is reduced, the brake block moves inwards due to the reduction of centrifugal force, and normal operation is restored. The device has the advantages of simple structure, no need of power, automatic operation, safety and reliability.
