[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] First embodiment

[0027] Traditional high-speed rail electrical systems are usually powered by external energy. This not only consumes more power, but also increases the demand for external energy. When there are fewer passengers, it will also cause greater operating losses. In order to provide an independent power supply for the electrical system of the high-speed rail, optimize energy use, improve the overall energy efficiency of the high-speed rail, and reduce dependence on the external power grid, refer to Figure 1 - Figure 2 The present embodiment provides a high-speed rail intelligent air compression rotating permanent magnet generator charging device, which consists of a generator air intake pipe 12, a generator mounting bracket 13 and a generator mechanism. The generator mounting bracket 13 is fixedly installed on the inner side of the generator air intake pipe 12. The generator air intake pipe 12 can be installed at the head position of the high-speed rail. When the high-speed rail is running, a fast airflow enters the generator air intake pipe 12, drives the generator mechanism to generate electricity, and stores it for use by the electrical system of the high-speed rail.

[0028] The power generation mechanism in this embodiment is arranged on the generator mounting bracket 13 and is driven by wind to rotate and generate electricity when the high-speed rail is running. The power generation mechanism includes a generator housing 4 fixedly mounted on the top of the generator mounting bracket 13, and a generator rotor rotating shaft 10 arranged in the middle position of the generator housing 4. Generator rotor bearings 11 are fixedly arranged at the axis centers of both ends of the generator housing 4, and one end of the generator rotor rotating shaft 10 passes through the two generator rotor bearings 11 and is rotatably connected thereto. The generator rotor rotating shaft 10 rotates in the two generator rotor bearings 11, which can make the rotation of the generator rotor rotating shaft 10 feel stable.

[0029] Second embodiment

[0030] In order to convert mechanical energy into electrical energy by utilizing the power generated by air flow to provide power for the battery system of high-speed rail, refer to Figure 3 and Figure 5In this embodiment, a rotating assembly for driving the generator rotor rotating shaft 10 to rotate by wind force is provided at the end of the generator rotor rotating shaft 10 away from the generator housing 4. The specific implementation method is that the rotating assembly includes a generator rotating shaft 3 fixedly arranged at the end of the generator rotor rotating shaft 10 away from the generator housing 4, and three equally distributed generator blades are arranged on the generator rotating shaft 3. The diameters of the three generator blades gradually decrease along the axial direction of the generator rotating shaft 3. The gradually decreasing diameters of the three generator blades can help better manage the airflow, reduce eddy currents and resistance, thereby improving the rotation efficiency, and at the same time help to balance the overall structure of the generator, reduce the lateral force caused by the airflow, reduce vibration, and extend the service life of the charging device.

[0031] The generator blades include eight semi-fan-shaped blades 1 distributed in a circular array. The interval between two adjacent semi-fan-shaped blades 1 is 45°, and the semi-fan-shaped blades 1 are tilted downward by 30°. When the high-speed rail is running, the air flow drives the generator blades to rotate, which can obtain the maximum thrust area and accelerate the rotation speed of the generator blades. The semi-fan-shaped blades 1 made of carbon fiber material have the advantages of light weight, high strength and long life, which improves the practicality of the entire charging device.

[0032] A T-shaped fan blade mounting plate 2 detachably connected to the generator rotating shaft 3 is fixedly provided at the axis of the generator blade, so that the generator blade can be removed from the generator rotating shaft 3 for inspection or maintenance after long-term use.

[0033] Third embodiment

[0034] In order to achieve higher stability and reliability in the power generation process and reduce maintenance requirements, refer to Figure 4 and Figure 6 In this embodiment, a power generation component that generates current when the generator rotor rotating shaft 10 rotates is arranged on the inner side of the generator housing 4. The specific implementation method is that the power generation component is fixedly arranged on the generator rotor permanent magnet strip mounting barrel 9 outside the generator rotor rotating shaft 10, and twenty-four generator rotor permanent magnet strips 8 distributed in a circumferential array are fixedly arranged on the inner side of the generator rotor permanent magnet strip mounting barrel 9. A generator stator T-type permanent magnet strip mounting barrel 5 is fixedly installed on the inner side of the generator housing 4. Twenty-four generator stator T-type permanent magnet strips 6 distributed in a circumferential array are fixedly installed on the inner side of the generator stator T-type permanent magnet strip mounting barrel 5. The twenty-four generator rotor permanent magnet strips 8 are respectively matched with the twenty-four generator stator T-type permanent magnet strips 6, and the magnetic poles of several generator rotor permanent magnet strips 8 and the generator stator T-type permanent magnet strips 6 are arranged alternately. When the generator rotor permanent magnet strip mounting barrel 9 drives the generator rotor permanent magnet strip 8 to rotate, the twenty-four generator rotor permanent magnet strips 8 rotate on the inner side of the twenty-four generator stator T-type permanent magnet strips 6 respectively.

[0035] Generator stator copper coils 7 fixed to the generator stator T-shaped permanent magnet bar mounting barrel 5 are respectively arranged on both sides of the generator stator T-shaped permanent magnet bar 6. The generator stator copper coils 7 are electrically connected to a regulator through wires, and the regulator is connected to the battery wires of the high-speed rail. The current generated by the generator stator copper coils 7 is transmitted to the battery for storage through the regulator. The generator stator T-shaped permanent magnet bar mounting barrel 5 and the generator rotor permanent magnet bar mounting barrel 9 are made of aluminum alloy material, which reduces the wear of mechanical parts and improves the stability and reliability of the system.

[0036] The present invention has a compact structure, small size, light weight, high efficiency and large output power. It runs at high speed on a high-speed rail, so that a fast airflow enters the generator air intake pipe 12. The rotating assembly drives the generator rotor rotating shaft 10 to start rotating. The generator rotor rotating shaft 10 drives the generator rotor permanent magnet bar 8 of the power generation assembly to rotate. The generator rotor permanent magnet bar 8 rotates on the inner side of the generator stator T-shaped permanent magnet bar 6, so that the generator stator copper coil 7 generates current. Through efficient energy conversion and recovery, carbon emissions and environmental impacts in operation are reduced, which helps to achieve green travel.

[0037] When the charging device is actually used on the high-speed railway, the fast airflow generated by the high-speed railway running at high speed enters the generator air intake pipe 12, and the high-speed airflow drives the three generator blades to rotate at the same time, and the three generator blades drive the generator rotating shaft 3 to rotate at the same time, and the generator rotating shaft 3 drives the generator rotor rotating shaft 10 at one end thereof to start rotating, and the generator rotor rotating shaft 10 drives the generator rotor permanent magnet bar mounting barrel 9 to rotate, and the generator rotor permanent magnet bar mounting barrel 9 drives the twenty-four generator rotor permanent magnet bars 8 inside it to rotate at the same time, and the generator rotor permanent magnet bar 8 rotates on the inner side of the generator stator T-type permanent magnet bar mounting barrel 5, and the generator stator T-type permanent magnet bar 6 is fixedly installed on the inner side of the generator stator T-type permanent magnet bar mounting barrel 5, and the generator rotor permanent magnet bar 8 rotates on the inner side of the generator stator T-type permanent magnet bar 6, so that the generator stator copper coil 7 generates current, and the generated current is transmitted to the high-speed railway battery through the regulator for storage for use by the high-speed railway electrical equipment.
