Embodiment 1

[0036] refer to figure 1 and figure 2 , figure 1 It is a schematic diagram of the overall mechanism of the wind power generation device provided by the embodiment of the present invention, figure 2 The structural schematic diagram of the air collector module provided for the embodiment of the present invention is described in detail as follows:

[0037] The wind power generation device consists of 4 modules, including wind collector module 1, generator module 2, exhaust module 3 and support module 4;

[0038] The air collector module is provided with an air guide pipe, and an air collection port 14 communicating with the air guide pipe;

[0039] The power generation module is provided with a pipe connected to the air collecting port 14, and a generator assembly in which the blades are connected with the inner rotor in the pipe.

[0040] Wherein, there is a mounting structure on the inner wall or the outer wall of the air collector module, and the power generation module ...

Embodiment 2

[0047] refer to figure 1 and figure 2 , the present embodiment mainly describes the use of each component in the air collector module 1, detailed as follows:

[0048]The top of the wind collector module 1 is a thin-walled end cover 11, which is used to prevent rainwater. The end cover 11 is connected to the inner air guide pipe 131 through the rib plate 12 . The inner air guide pipe 131 and the outer layer air guide pipe 132 are also connected by ribs 12 . Due to the existence of the ribs 12 , the air introduced from each air inlet has little influence on other air inlets, and will not flow out from other air inlets, so that the introduced air flows to the air collecting port 14 .

[0049] In the embodiment of the present invention, the air introduced through the air inlet will drive the air at the lower port of the inner air guide pipe to flow downward, thereby reducing the wind pressure here and forming a pressure at the upper and lower ports of the inner air guide pipe....

Embodiment 3

[0051] refer to image 3 and Figure 4 , image 3 It is a schematic diagram of the full section of the generator module provided by the embodiment of the present invention, Figure 4 The exploded schematic diagram of the generator module provided by the embodiment of the present invention is described in detail as follows:

[0052] The outer wall of the generator module 2 is connected by the upper thin-walled cylinder 211 and the lower thin-walled cylinder 212 through flanges, the support frame 27 is fixed on the inner wall of the lower layer thin-walled cylinder 212, and the inner rotor 24 of the motor is installed above the support frame 27 through the shaft 25 and the bearing group 26 . The inner and outer rings of the inner rotor 24 of the motor are connected by thin-walled blades, and one end of the shaft 25 is made into a fairing form to adjust the wind direction so that more air passes through the blades connected to the inner rotor. The magnetic poles 23 are surfac...

Abstract

The invention is suitable for the field of new energy application, and provides a wind power generation device. The wind power generation device comprises a wind collector module and a power generation module, wherein the wind collector module is provided with a wind guide pipe and a wind collecting port communicated with the wind guide pipe; and the power generation module is provided with a pipe in butt joint with the wind collecting port, and a generator module positioned in the pipe and with a blade and an inner rotor connected integrally. The wind power generation device adopts a split design to separate the wind collector module and the power generation module, so that the installation and the maintenance are convenient; a principle of multiplying the wind speed by the wind collector module is used for replacing an acceleration gearbox, so that the power generation efficiency is improved; and the blade and the rotor of the generator are integrated in the wind guide pipe, so that the blade radius is decreased, and the appearance design of the whole wind power generation device is facilitated. Multiple problems caused by the gearbox are eliminated; the wind energy utilization rate and the transmission efficiency of the whole system are improved; and the flexibility and the convenience for installation and maintenance are improved.

Description

technical field [0001] The invention relates to the field of new energy applications, in particular to a wind power generating device which adopts a split design and separates a wind collector module and a power generation module. Background technique [0002] Wind energy is an inexhaustible clean energy, which has been widely concerned and continuously developed and utilized rationally and efficiently. The most common application is to use natural wind to drive wind turbines to generate electricity. According to the direction of the main shaft, wind turbines can be divided into horizontal axis wind turbines and vertical axis wind turbines. [0003] No matter what kind of wind power generation device, the windmill wings that bear the wind are all exposed outside the cabin. The wind power generator is located in the nacelle on the column, which is equipped with: the rotor head with the windmill blade installed, the main shaft connected with the rotor head and rotated as a w...
