Embodiment Construction
[0040] Such as Figure 5 , 6 As shown, the wind turbine includes at least 6 coaxial and vertical wind rotors 2, each of which is staggered by 30 degrees in the horizontal plane. Around each wind wheel 2, an outwardly expanding flared wind tunnel 1 is respectively set in the four directions of east, west, north, south, the small mouth of the flared wind tunnel 1 is the air outlet, the big mouth is the air inlet, and the big mouth is facing the wind wheel 2. The small opening is offset along the rotation direction of the wind wheel 2, so that all the wind is led to the work blades of the wind wheel 2; The two ends are connected with the upper and lower cover plates, and the height of the flaring wind tunnel is consistent with that of the wind wheel.
[0041]The wind tunnel type wind power machine of the present invention relies on the wind tunnel to collect wind energy and transfers it to the wind wheel. Since the wind receiving area of the wind tunnel is much larger than t...

A wind-tunnel type vertical axis wind generator set is characterized in that every wind generator comprises at least six wind turbines which are coaxially and vertically arranged, and the east, west, south and north directions around every wind turbine are respectively provided with an outwards-flared wind tunnel; a fixedly-arranged secondary side is disposed inside the inner cavity of a primary side of a rotating transformer, and the primary side rotates around the secondary side; a stator is disposed inside the inner cavity of a rotor of a synchronous generator, and the rotor of the synchronous generator rotates along with the primary side of the rotating transformer synchronously; and a transmission shaft at the lower end of every turbine of the wind generator is directly connected with the upper end cover of the generator to form a direct drive wind generator set. The wind-tunnel type vertical axis wind generator set has the advantages that the generator can avoid armature reaction and is provided with reduced external characteristics and constant power characteristics. When connected to a power grid, once the grid voltage drops suddenly to result in a sudden short circuit, the wind-tunnel type vertical axis wind generator set does not need to be off-grid, so that the wind speed control and the power control of a wind power system can be omitted, not only the cost of the wind power system can be reduced significantly, but also the annual energy generating capacity of the wind power system can be increased greatly, and the wind electric field can be improved significantly.
Description
technical field [0001] The invention relates to the technical field of wind power generation, in particular to a wind tunnel type vertical axis wind power generating set. Background technique [0002] Wind power generation has lasted for more than half a century, and the development of wind power is still struggling. In the final analysis, it is caused by two technical problems of wind power: one is the difficulty of connecting wind power to the grid, and the other is the low efficiency of wind turbines. For a long time, the wind power industry has been using high-tech means outside the generator and wind turbine to solve these two major wind power technical problems, but the wind power industry is in trouble because of the high cost. It has always been the biggest obstacle to the development of wind power. Contents of the invention [0003] The purpose of the present invention is to provide a wind tunnel type vertical axis wind power generating set, which solves the prob...
