Multilevel narrow tube wind-gathering wind power generation system

Abstract

The invention relates to a multilevel narrow tube wind-gathering wind power generation system which comprises narrow tubes. The narrow tubes are composed of frameworks and wall face plates, and wind guide structures are arranged in the narrow tubes. The wind power generation system further comprises impeller assemblies and electric generators, the electric generators are arranged on racks in wind guide cones of the wind guide structures, and the racks are arranged at the centers of frameworks of the wind guide cones. Wind guide plates are annularly arranged on the outer sides of wind guide cone bodies, one end of a supporting rod at the center of each wind guide plate is fixedly arranged on a base on the outer side of the corresponding wind guide cone, the other ends of the supporting rods are fixedly arranged on the inner sides of narrow tube bodies, and thus the gravity supporting function and the wind direction rectifying function can be achieved. Rear-mounted blades are annularly mounted on the outer sides of compound ring type impellers, the impellers are mounted on shaft heads of the electric generators, and therefore a set of front narrow tube wind power generation system is formed. The diameter of the rear narrow tube is larger than the diameter of the front narrow tube, and the rear narrow tube is arranged on a tail stream exhaust port of the front narrow tube in a compound coaxial line sleeving mode through the same assembly. A wind finding structure is mounted on the tail portion of the rear narrow tube. According to the multilevel narrow tube wind-gathering wind power generation system, the multilevel split-axle narrow tube wind gathering and power generation mode is adopted, and the utilization efficiency and the generating efficiency of wind energy can be improved.

Description

technical field [0001] The invention relates to the technical field of wind power generation equipment, in particular to a narrow tube wind gathering wind power generation system. Background technique [0002] The wind-gathering wind generator produced according to the narrow tube effect has a wide range of development and application prospects in the field of wind power generation technology because of its advantages of gathering wind energy, increasing pressure and increasing speed, and improving wind energy utilization.

Problems solved by technology

As we all know, if the narrow tube wind collection method is used to generate electricity, once the power is increased, the model will inevitably increase, and the diameter of the narrow tube will also need to be increased accordingly. The bigger it is, the heavier it is, and the more difficult it is to transport and install

In addition, the material and shape of the wall surface of the tube body that play the role of a real narrow tube also require a more suitable method, shape, and close cooperation with the joints of the components; secondly, for a high-power narrow tube power generation system, it is necessary to design a more favorable wind in the tube Increase speed and reduce friction loss, and can also play the dual functions of wind guide and support; more importantly, after the power is increased, if the existing public blades are used, the blades are easy to deform, so it needs to be redesigned A new type of blade that can be adapted to complete energy absorption conversion and power output in a narrow tube in a high-power system
