Description

Technical Field

[0001] The present invention relates to the technical field of wind turbine generators, and more particularly to a wind turbine generator device capable of generating electricity with high efficiency. Background Art

[0002] A wind turbine is a device that converts wind energy into electrical energy. Its working principle is based on the wind driving the rotor blades to rotate, and the speed is increased by the speed increaser, which drives the generator to generate electricity. The rotor blades capture the kinetic energy of the wind and convert it into mechanical energy, which is then converted into electrical energy. However, during the wind blowing process, only the front blades are always under force, so there is a lot of waste in other blades, resulting in low efficiency.

[0003] After searching, the Chinese patent with announcement number CN220539754U discloses a full wind energy wind turbine device and mounting frame. The invention adopts a cylindrical impeller and cooperates with a wind splitter to make its setting more reasonable and the utilization efficiency higher. The cylindrical impeller is usually arranged vertically and occupies less space in actual installation. The various mechanisms can be large or small as a whole according to the usage scenario, and the applicability is better.

[0004] When the above-mentioned wind turbine is in use, the wind moves along the working surface of the wind distributor, driving the wind wheel to rotate, and the wind force is transmitted to the generator to generate electricity. However, it is not convenient to dynamically adjust the blade angle according to changes in wind speed and wind direction. When the wind speed changes greatly, the efficiency of capturing wind energy is low, which in turn affects the power generation efficiency. Summary of the invention

[0008] Furthermore, a base is provided at the bottom end of the support column, a top end of the base is fixedly connected to a limiting ring, and the limiting ring is movably sleeved on the support column.

[0009] Furthermore, a mounting plate is fixedly connected to the outer bottom edge of the base.

[0010] It can be seen that in the above technical solution, the mounting plate is installed by bolts, so that the base can be installed and fixed.

[0011] Furthermore, a rotating assembly is disposed inside the base, and the rotating assembly includes a second stepper motor, a fourth rotating shaft, a second gear, a third rotating shaft and a first gear, and the second stepper motor is fixedly mounted on the inner bottom end of the base.

[0012] Furthermore, the top end of the fourth rotating shaft is movably connected to the base via a bearing, and the bottom end of the fourth rotating shaft is fixedly connected to the output shaft end of the second stepper motor, the second gear is fixedly sleeved on the fourth rotating shaft, and the second gear is meshed with the first gear, the first gear is fixedly sleeved on the third rotating shaft, the top end of the third rotating shaft is fixedly connected to the support column, and the bottom end of the third rotating shaft is movably connected to the base via a bearing.

[0014] Furthermore, both the second stepper motor and the first stepper motor are equipped with an electromagnetic locking structure.

[0015] It can be seen that in the above technical solution, the first stepper motor can lock the three blades, and the second stepper motor can lock the support column.

[0017] 1. The present invention drives the first rotating shaft to rotate by the first stepper motor, and the first rotating shaft can drive the three second rotating shafts to rotate through the bevel gear set, thereby driving the three blades to rotate.

The operation is simple, and the angles of the three blades can be dynamically adjusted according to the changes in wind speed and wind direction, which effectively improves the capture efficiency of wind energy, thereby improving the power generation efficiency;

[0018] 2. The present invention drives the fourth shaft to rotate through the operation of the second stepper motor, thereby driving the second gear to rotate.
