Wind tunnel convergent type power generator

Abstract

A wind tunnel collecting generator comprises a frame, a turbine rotor, a snuffle valve and a tail wing. The frame is reduced stepped and then expanded. The turbine rotor is arranged in the frame. The snuffle valve is on the wall of the frame. The tail wing is arranged on the face of frame. Via the acceleration of frame, the improved efficiency of turbine rotor and the reduced pressure of snuffle valve, the inventive generator can own wide operation range, low occupied space, low heavy, low noise and high efficiency.

Description

technical field [0001] The invention relates to a wind tunnel convergence type power generator, in particular to a wind tunnel convergence type power generator with small volume and high efficiency. Background technique [0002] As the world's oil production decreases and the greenhouse effect becomes more and more serious, countries around the world are committed to developing non-polluting energy, so wind power and solar power have become popular targets. [0003] Known wind power generator 1 (as Fig. 1), it comprises generator body 11, windmill 12, empennage 13 and fixed frame 14; Fixed frame 14 connects generator body 11 with a bearing (figure omitted), and generator body 11 The windmill 12 is connected with another bearing, and a plurality of blades 121 are arranged on the windmill 12, and the blades 121 and the axis line of the rotating shaft connected to the windmill 12 all have a fixed acute angle, and the empennage 13 is arranged on the shell of the generator body 1...

Problems solved by technology

[0004] However, in order to increase the generating power, the wind generator 1 generally achieves the effect of generating relatively large energy at a relatively small wind speed by increasing the area of ​​the blades 121, and generally increases the length of the blades 121 to achieve the purpose of increasing the area, so that the wind force The generator 1 must be suitable for use in a larger space, and the longer blades 121 also make the wind generator have a heavier weight

Moreover, in order to avoid damage to the wind power generator 1 due to excessive wind speed, a wind speed at shutdown can be set, so that the wind with a higher wind speed cannot be used to generate electricity

In addition, because the empennage 13 passively controls the direction of the wind turbine 1 through the wind direction, it is sometimes impossible to face the windward side accurately, and even the wind direction is 0 degrees, 90 degrees to the windmill 12 of the wind turbine 1. degrees or 270 degrees, it may cause the empennage 13 to be unable to play the effect of controlling the steering of the wind turbine 1

[0005] In view of the fact that the known wind generators need to occupy a large space, cannot utilize the wind of higher wind speed and the empennage may not be able to exert the effect of controlling the steering of the wind generator, so the present invention which can effectively improve the above-mentioned problems is proposed
