Description

Technical field

[0001] The present utility model relates to the technical field of a power generation device, in particular a wind-powered compressed air power generation device. By converting wind energy into compressed air energy and subsequently driving a generator to produce electricity, an efficient use of clean energy is enabled, while simultaneously providing energy storage and continuous power generation. State of the art

[0002] Conventional wind power generation technology relies primarily on the direct drive of generators by wind turbines, whose power generation efficiency is highly dependent on fluctuations in wind speed. Furthermore, it lacks energy storage capacity, making a stable power supply difficult to achieve. In addition, existing compressed air energy storage systems often depend on external power sources, resulting in a relatively low energy utilization rate. Therefore, a device that integrates wind energy capture, compressed air energy storage, and stable power generation is urgently needed to address these challenges. Content of the utility model

[0003] To solve the problems existing in the prior art, the present utility model proposes a wind-powered compressed air power generation device which specifically includes the following: Wind-powered compressed air power generating device, comprising drive blades, an electric air compression unit, a generator; several of the drive blades are arranged around a connecting rod at identical angles; the connecting rod is connected at the bottom to a first gearbox, which is engaged with a second gearbox; a cam rod is provided on the second gearbox, the end of which is connected to a piston on an air compressor, pushing the piston to generate air pressure; an output end of the air compressor is connected to one end of a high-pressure gas storage tank, which is used to monitor the air pressure inside the tank and automatically controls the opening of a valve when a predetermined value is reached; a gas nozzle is provided at the other end, on which a valve is provided; impellers are provided above the gas nozzle.which are connected to the generator, the generator is driven to generate electricity when the impellers are turned by the spray of gas.

[0004] Furthermore, a pressure gauge is provided on the high-pressure gas storage tank, which is used to monitor the air pressure inside the tank and automatically controls the opening of the valve when a predetermined value is reached.

[0005] Furthermore, the diameter of the first gear unit is larger than the diameter of the second gear unit to allow for an increase in speed.

[0006] Furthermore, the cam rod converts the rotary motion of the second gear unit into a linear motion of the piston through a lifting motion, thus driving the air compressor into operation.

[0007] Furthermore, the direction of the gas spray from the gas nozzle is adapted to a blade angle of the impellers, maximizing the kinetic energy of the gas and converting it into the kinetic energy of the rotation of the impellers.

[0008] Furthermore, the electric air compression unit is supplied with electricity by the generator in order to maintain the air pressure of the high-pressure gas storage tank in the event of insufficient wind power, thus ensuring continuous operation of the power generation device.

[0009] The above technical solution has the following advantageous effects: The present utility model converts wind energy into mechanical energy via drive blades. A first and a second gear unit are driven to rotate the turbine. The second gear unit, via a cam rod, drives the piston of an air compressor, generating compressed air which is stored in a high-pressure gas storage tank. A pressure gauge in the high-pressure gas storage tank monitors the air pressure. The valve opens automatically, and the compressed air is released from a gas nozzle when a predetermined pressure is reached. This sets the impellers in motion, driving the generator to produce electricity. A portion of the electricity generated by the generator powers the electric air compressor. This compressor supplements the compressed air supply when wind power is insufficient, thus maintaining the air pressure in the high-pressure gas storage tank.The device enables the conversion of wind energy into compressed air energy and, through energy storage and a closed-loop system, solves the problem of instability in wind power generation. The design of the gearbox increases the rotational speed, the cam rod converts the rotary motion into linear motion, and the precise fit of the gas nozzle and impellers optimizes energy transfer efficiency. The introduction of the electric air compression unit ensures the continuity of power generation, allowing the device to operate stably under varying wind conditions.

[0012] Example 1: in conjunction with Fig.A wind-powered compressed air power generating device is described, comprising drive blades 4, an electric air compression unit 3, and a generator 1. Several of the drive blades 4 are arranged around a connecting rod 11 at identical angles above it. The connecting rod 11 is connected at its bottom to a first gearbox 5, which is engaged with a second gearbox 6. A cam rod 7 is provided on the second gearbox 6, the end of which is connected to a piston on an air compressor 8. The cam rod pushes the piston to generate air pressure. An outlet end of the air compressor 8 is connected to one end of a high-pressure gas storage tank 9. A gas nozzle 13, on which a valve 12 is provided, is provided at the other end of the high-pressure gas storage tank 9. Impellers 2, connected to the generator 1, are provided above the gas nozzle 13.Generator 1 is driven to generate electricity when the impellers 2 are rotated by the injection of gas.

[0013] In the present embodiment, a pressure gauge 10 is provided on the high-pressure gas storage tank 9. This gauge is used to monitor the air pressure inside the tank and automatically controls the opening of the valve 12 when a predetermined value is reached. The diameter of the first gear unit 5 is larger than the diameter of the second gear unit 6 to allow for an increase in rotational speed. The cam rod 7 converts the rotary motion of the second gear unit 6 into a linear motion of the piston by means of a stroke movement, thus driving the air compressor 8 into operation. The direction of gas spray from the gas nozzle 13 is adapted to a blade angle of the impellers 2, maximizing the kinetic energy of the gas and converting it into the kinetic energy of the rotation of the impellers 2.The electric air compression unit 3 is supplied with electricity by the generator 1 in order to maintain the air pressure of the high-pressure gas storage tank 9 in the event of insufficient wind power, thus ensuring continuous operation of the power generation device.

[0014] In the design process, a four-blade structure is used for the drive blades 4; each pair of blades is symmetrical to each other. Carbon fiber is used for the connecting rod 11 to reduce weight, and its lower end is rigidly connected to the first gearbox 5 by a coupling. The gear ratio of the first gearbox 5 to the second gearbox 6 is 5:1. An output shaft of the second gearbox 6 is connected to the cam rod 7 by an eccentric gear mechanism. The stroke of the cam rod 7 is 1.2 times the stroke of the piston to ensure sufficient compression.

[0015] The air compressor 8 uses a composite structure; each cylinder has a volume of 0.5 cubic meters, and an operating pressure range of 0.8 to 1.3 MPa is provided. The gas nozzle 13 is designed as a reduction nozzle; its diameter is adjusted between 50 and 100 mm according to the size of the impeller 2, and the gas spray angle to the impeller blades 2 is 30°. The impellers 2 are made of an aluminum alloy, have a diameter of 1.2 meters, and feature 12 blades with a radially variable blade rotation angle. The generator 1 is a permanent magnet synchronous generator with a rated output of 5-50 kW, depending on the system size. The power output of the electric air compressor unit 3 is 20% of the rated output of generator 1; various load requirements are adapted using frequency converter control.

[0016] The present utility model converts wind energy into mechanical energy by means of the drive blades 4. The first gearbox 5 and the second gearbox 6 are driven to rotate. The second gearbox 6, via the cam rod 7, drives a piston movement of the air compressor 8, generating compressed air which is stored in the high-pressure gas storage tank 9. A pressure gauge 10 of the high-pressure gas storage tank 9 monitors the air pressure. The valve 12 opens automatically, and the compressed air is injected from a gas nozzle 13 when a predetermined value is reached. Impellers 2 are driven to rotate, and the generator 1 is driven to generate electricity. Part of the electrical energy generated by the generator 1 powers the electric air compressor 3. The electric air compressor 3 supplements the compressed air supply when wind power is insufficient, thus maintaining the air pressure in the high-pressure gas storage tank 9.The device enables the conversion of wind energy into compressed air energy and, through energy storage and a closed-loop system, solves the problem of instability in wind power generation. The design of the gearbox increases the rotational speed, the cam 7 converts the rotary motion into linear motion, and the precise fit of the gas nozzle 13 and the impellers 2 optimizes energy transfer efficiency. The inclusion of the electric air compression unit 3 ensures continuous power generation, allowing the device to operate stably under varying wind conditions.
