[0023] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a special wind deflector device for a vertical axis wind turbine generator set, comprising: a bracket 1 and a generator body 3, the outer surfaces of the four sides of the bracket 1 are evenly and fixedly connected with a plurality of wind deflector components 2; the wind deflector component 2 comprises two fixed blocks 203, the tops of the two fixed blocks 203 are each provided with a T-slot 205, the inner surfaces of the two T-slots 205 are both slidably connected with a T-block 202, the front surfaces of the two T-blocks 202 are both fixedly connected with a connecting plate 204, the front surfaces of the two connecting plates 204 are fixedly connected with a wind deflector body 201, the cross section of the wind deflector body 201 is wavy, and the two fixed The outer surface of the fixed block 203 is penetrated by threaded holes 209, the outer surfaces of the two fixed blocks 203 are fixedly connected to the outer surface of the bracket 1, the inner surfaces of the two threaded holes 209 are threadedly connected with bolts 208, the inner surface of the bracket 1 is equidistantly fixedly connected with multiple placement racks 7, the tops of the multiple placement racks 7 are fixedly connected with rotating seats 8, the inner surfaces of the multiple rotating seats 8 are rotatably connected with the rotating shaft 4 through bearings, the outer surface of the rotating shaft 4 is equidistantly fixedly connected with multiple connecting sleeves 6, the outer surfaces of the multiple connecting sleeves 6 are equidistantly fixedly connected with multiple fan blades 5, and the outer surfaces of the two T-blocks 202 are provided with through holes 206.

[0024] The effect achieved by the entire embodiment 1 is that multiple wind guide components 2 are fixed on the four sides of the bracket 1. When the external wind blows onto the fan blades 5, the connecting sleeve 6 will drive the rotating shaft 4 to rotate, so that the rotating shaft 4 rotates along the bearing on the rotating seat 8, thereby driving the output end of the generator body 3 to rotate, and the mechanical energy generated by the movement is converted into electrical energy by the generator, thereby realizing power generation. Before power generation, the two T-blocks 202 on the wind guide plate body 201 can be aligned with the T-slots 205 on the fixing block 203, and then the wind guide plate body 201 can be pressed downward to insert the T-block 202 into the T-slots 205, so that the threaded hole 209 is aligned with the through hole 206 on the T-block 202, and then the bolt 208 is screwed into the threaded hole 209 and inserted into the through hole 206, so as to complete the quick installation of the wind guide plate body 201 and fix it on the four sides of the bracket 1. As for the wavy wind guide plate body 201 installed on all four sides of the bracket 1, when the airflow passes through the wavy wind guide plate body 201, the airflow will flow relatively smoothly along the curve, reducing the airflow separation and vortex generation on the leeward side, effectively reducing the reverse resistance of the wind wheel when it is operating to generate electricity under the wind, increasing the utilization rate of wind energy, and providing the efficiency of converting wind energy into electrical energy. When the wind guide plate body 201 needs to be damaged and needs to be disassembled, the above operation can be reversed to quickly disassemble the wind guide plate body 201, which is convenient for maintenance or replacement. At the same time, when fixing the wind guide plate body 201, a plurality of first circular holes can be opened on the wind guide plate body 201, and a plurality of second circular holes can be opened at the designated position of the bracket 1.

The nut 207 is tightened on the bolt 208 to strengthen the fixing effect of the T-block 202, so that the air deflector body 201 is more stable after being fixed. Then, when the external wind blows onto the fan blades 5, the connecting sleeve 6 will drive the rotating shaft 4 to rotate, so that the rotating shaft 4 will rotate along the bearing on the rotating seat 8, thereby driving the output end of the generator body 3 to rotate, and the mechanical energy generated is converted into electrical energy by the generator, thereby realizing power generation. At the same time, when the airflow passes through the wavy wind guide plate body 201, the airflow will flow relatively smoothly along the curve, reducing the airflow separation and vortex generation on the leeward side, effectively reducing the reverse resistance of the fan blades when they are operated by wind to generate electricity, increasing the utilization rate of wind energy, and providing the efficiency of converting wind energy into electrical energy.
