Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0015] Example 1, see Figure 1A wind power compressed air power generation device shown in the figure includes a power wind blade 4, an electric air compressor unit 3, and a generator 1. A plurality of power wind blades 4 are arranged above a connecting rod 11 at equal angles around the connecting rod 11. The lower part of the connecting rod 11 is connected to a first speed-changing gear 5. The first speed-changing gear 5 is meshed and connected to a second speed-changing gear 6. A crank rod 7 is arranged on the second speed-changing gear 6. One end of the crank rod 7 is connected to a piston on an air compressor 8 to push the piston to generate air pressure. The output end of the air compressor 8 is connected to one end of a high-pressure gas storage tank 9. The other end of the high-pressure gas storage tank 9 is provided with a jet port 13. A valve 12 is arranged on the jet port 13. An impeller 2 is arranged above the jet port 13. The impeller 2 is connected to the generator 1. When the impeller 2 rotates driven by gas injection, it drives the generator 1 to generate electricity.

[0016] In this embodiment, a pressure indicating meter 10 is arranged on the high-pressure gas storage tank 9 to monitor the air pressure in the tank and automatically control the opening of the valve 12 when the set value is reached. The diameter of the first speed-changing gear 5 is larger than that of the second speed-changing gear 6 to achieve speed increase. The crank rod 7 converts the rotational motion of the second speed-changing gear 6 into the linear motion of the piston through reciprocating motion to drive the air compressor 8 to work. The gas injection direction of the jet port 13 matches the blade angle of the impeller 2 to maximize the conversion of gas kinetic energy into the rotational kinetic energy of the impeller 2. The electric air compressor unit 3 is powered by the generator 1 and is used to maintain the air pressure in the high-pressure gas storage tank 9 when the wind power is insufficient to ensure the continuous operation of the power generation device.

[0017] In the specific implementation process, the power wind blade 4 adopts a four-blade structure, and the blades are symmetric in pairs. The connecting rod 11 is made of carbon fiber material to reduce weight, and its lower end is rigidly connected to the first speed-changing gear 5 through a coupling. The tooth number ratio of the first speed-changing gear 5 to the second speed-changing gear 6 is 5:1. The output shaft of the second speed-changing gear 6 is connected to the crank rod 7 through an eccentric wheel mechanism. The stroke length of the crank rod 7 is set to 1.2 times the piston stroke to ensure sufficient compression.

[0018] The air compressor 8 adopts a compound structure, and the volume of each cylinder is 0.5 cubic meters. The working pressure range is set to 0.8 - 1.2 MPa. The jet port 13 is designed as a tapered nozzle, and the outlet diameter is adjusted to 50 - 100 mm according to the size of the impeller 2. The jet angle forms a 30° angle with the blades of the impeller 2. The impeller 2 is made of aluminum alloy material, with a diameter of 1.2 meters and 12 blades. The blade twist angle changes gradually along the radial direction. The generator 1 selects a permanent magnet synchronous generator, and the rated power is configured to be 5 - 50 kW according to the system scale. The power of the electric air compressor unit 3 is 20% of the rated power of the generator 1, and frequency conversion control is adopted to match different load requirements.

[0019] In the present invention, wind energy is converted into mechanical energy by the power wind blade 4, driving the first speed-changing gear 5 and the second speed-changing gear 6 to rotate. The second speed-changing gear 6 drives the piston movement of the air compressor 8 through the crank lever 7 to generate compressed air and store it in the high-pressure gas storage tank 9. The pressure indicator 10 of the high-pressure gas storage tank 9 monitors the air pressure. When the set value is reached, the valve 12 automatically opens, and the compressed air is ejected from the jet port 13 to push the impeller 2 to rotate and drive the generator 1 to generate electricity. Part of the electric energy generated by the generator 1 is supplied to the electric air compressor unit 3. The electric air compressor unit 3 supplements compressed air when the wind power is insufficient to maintain the air pressure in the high-pressure gas storage tank 9. This device realizes the conversion of wind energy to compressed air energy, and solves the problem of unstable wind power generation through energy storage and energy recycling. The design of the speed-changing gear increases the rotation speed. The crank lever 7 converts the rotational motion into a linear motion. The matching design of the jet port 13 and the impeller 2 optimizes the energy transfer efficiency. The introduction of the electric air compressor unit 3 ensures the continuity of power generation, enabling the device to operate stably under different wind conditions.
