[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and ultimately outputs alternating current. A wind turbine generally consists of components such as a wind wheel, a generator, a direction regulator, a tower, a speed limit safety mechanism and an energy storage device. The working principle of a wind turbine is relatively simple. The wind wheel rotates under the action of wind, and it converts the kinetic energy of the wind into the mechanical energy of the wind wheel shaft. The generator rotates and generates electricity driven by the wind wheel shaft. Broadly speaking, wind energy is also solar energy, so it can also be said that a wind turbine is a heat energy generator that uses the sun as a heat source and the atmosphere as a working medium.

[0022] See also Figure 1-4 , the present invention provides a technical solution:

[0023] A bird-repellent power generation wind turbine guide cover comprises a first cover surface 2 and a second cover surface 6, wherein the second cover surface 6 is arranged at the upper left end of the first cover surface 2, and the second cover surface 6 is fixedly connected to the first cover surface 2 by internal screws, and the third cover surface 7 is arranged at the lower left end of the first cover surface 2, and the third cover surface 7 is fixedly connected to the first cover surface 2 by internal screws, and the second cover surface 6 and the third cover surface 7 are also connected by internal screws, and the top ends of the first cover surface 2, the second cover surface 6 and the third cover surface 7 are all provided with an impeller fixing groove 1, and the impeller fixing groove 1 is fixedly connected to the top ends of the first cover surface 2, the second cover surface 6 and the third cover surface 7 by welding, and the top end of the impeller fixing groove 1 is provided with an impeller fixing groove section 8, and the impeller fixing groove section 8 is fixedly connected to the top end of the impeller fixing groove 1 by welding, and the annular surface of the impeller fixing groove section 8 is provided with an impeller fixing screw groove 9, and the impeller fixing A fixed screw groove 9 passes through the impeller fixing groove section 8, an impeller port 10 is arranged in the middle of the top of the impeller fixing groove 1, and the impeller port 10 passes through the impeller fixing groove 1, and a guide end 4 is arranged at the front end of the first cover surface 2, the second cover surface 6 and the third cover surface 7, and the guide end 4 connects the first cover surface 2, the second cover surface 6 and the third cover surface 7 through internal screws, and a guide tip 3 is arranged at the front end of the guide end 4, and the guide tip 3 is fixedly connected to the front end of the guide end 4 by welding, and a guide cover fixing section 12 is arranged at the rear end of the first cover surface 2, the second cover surface 6 and the third cover surface 7, and the guide cover fixing section 12 is fixedly connected to the first cover surface 2, the second cover surface 6 and the third cover surface 7 by screws, and a guide cover fixing screw groove 11 is arranged on the annular surface of the guide cover fixing section 12, and the guide cover fixing screw groove 11 passes through the surface of the guide cover fixing section 12.
