Description

New energy extended program air rail train and empty iron system using the train

Technical field

The invention relates to the technical field of rail transit, in particular to a new energy extended program air rail train and an empty iron system using the train.

Background technique

With the changes of the times, the urbanization process has been accelerating, so the scale of the city has grown rapidly. With the accelerated pace of life and the rapid increase in the number of urban populations, people’s travel volume is increasing. The increase in travel is not limited to individual cities, but has spread to between urban and rural areas. Between cities.

Existing traffic has been unable to satisfy people's travel, and all major cities in the world have different levels of car congestion. Therefore, people have been looking for ways to solve the traffic congestion problem caused by the increasing amount of travel. Because the airborne train moves the ground traffic into the air, it is in many cities based on the small impact on the ground building facilities during the construction process, the fast running speed of the train after opening, the flexible laying of the track, and the pollution to the environment during the operation. The city and the city have developed rapidly.

Due to the overhead arrangement of the empty rail, the vehicle is hung below the track, and the empty rail may pass through densely populated areas. This requires that the empty rail is different from the traditional railway and requires a more energy-demanding system. The free iron rail train system can lay a more solid foundation for the further development of China's airborne rail trains.

Summary of the invention

The invention provides a new energy increasing program air rail train and an air iron system using the same, which is used for solving the energy supply problem of the air rail train using the battery as a power source.

The new energy extended program air rail train provided by the present invention and the empty iron system using the train solve the problem by the following technical points: a new energy extended program air rail train, including a vehicle body, which is provided with a vehicle body for driving the vehicle body a wheel assembly that moves along an orbit, the power source of the wheel assembly being electrical energy;

Also included is a battery pack for providing electrical power to the wheel assembly, the battery pack being electrically coupled to the wheel assembly;

Also included is a supplemental generator for charging a battery pack, the supplemental generator being electrically connected to the battery pack, the supplemental generator being one or more of the following power generating devices: a fuel generator, a photovoltaic power generation system, Wind energy generators, hydrogen fuel generators.

Specifically, because of the flexible nature of the empty rail track, the empty rail track may pass through densely populated areas and/or buildings, which requires that the empty rail track be distinguished from the traditional rail car and requires more energy-critical energy. Supply system. As a clean energy source, electric energy, as a power source for airborne rail trains, has the advantage of not polluting the urban environment. Therefore, in this case The electric drive body is used to move along the track.

It is precisely because of the special nature of the empty rail track that may pass through densely populated areas, taking into account the cost of power erection and the safety of use of the vehicle by laying cables, especially since the cable may be particularly close to the production and living environment of human beings, Not only does it put forward higher requirements for the insulation performance of power cables, but the pollution caused by electromagnetic radiation may also damage the physical health and mental health of people in a certain range. This makes the airborne direct power supply. The promotion of trains is difficult.

The battery pack provided above provides energy for the operation of the vehicle body, that is, the battery pack is used as the energy storage component, which can effectively eliminate the dependence of the rail train on the continuous power supply, that is, by setting the charging device in the local safety area, the rail along the suspension rail is avoided. All the extension directions are set to the defects of the cable. The above battery pack is preferably a super battery, such as a graphene super capacitor, a graphene lithium ion surface battery, etc., so that it can not only adapt to the operation requirements of the air rail train, but also adapts the power supply of the motor with a power ranging from several kilowatts to several tens of kilowatts, for example, The traction motor with a power of 7-15KW realizes large current discharge, and also realizes fast charging and reduces the time required for power supply of the battery pack.

Due to different operating conditions of the vehicle body, such as load, running speed, number of starts and stops, acceleration during operation and braking, it is difficult for the train to have a constant maximum travel after a single charge of the battery pack. At the same time, if the charging of the battery pack, the train stop charging, etc., the train usage rate is reduced, the scheme further includes a supplemental generator for charging the battery pack, the supplemental generator and the battery pack. Through the wire connection, the battery pack can be charged as needed during the running of the train. The electric energy provided by the supplemental generator can effectively extend the travel journey of the train, reduce the stop time of the train, ensure that it completes the prescribed route or specifies the number of round trips. Carrying missions.

As a specific implementation form of the supplemental generator, the supplemental generator is one or more of the following power generating devices: a fuel generator, a photovoltaic power generation system, a wind energy generator, and a hydrogen fuel generator.

When adopting a fuel generator, considering that the existing advanced battery can be charged with high power, the priority fuel generator can select a generator with a slightly larger power, and the fuel generator moves along the track with the train to drive the train in sparsely populated areas. When the fuel generator is started, the battery pack is quickly charged. In this case, air pollution and noise pollution are not caused to densely populated areas.

When a photovoltaic power generation system is used, the photovoltaic panel is disposed on the surface of the vehicle body and/or along the track. When the photovoltaic panel is disposed on the surface of the vehicle body, the photovoltaic power generation system can be in the whole process of photoelectric conversion. The battery pack is supplied with electric energy; when the photovoltaic panel is arranged along the track, the solar energy can be utilized as much as possible. At this time, it is preferable to set the electric energy temporary storage device along the discontinuity of the track, such as using a battery, and setting along the track discontinuity and The plurality of charging rails that are separately electrically connected by the different electric energy temporary storage devices are electrically connected to the electric energy temporary storage device when the train travels to the track segment provided with the charging rail, so as to realize high-power charging of the battery pack; as a person skilled in the art When using photovoltaic panels along the track, you can also pass The form of the charging rail is set throughout the track.

The above wind power generation and setting form may adopt the above charging scheme of setting photovoltaic panels along the track.

In the hydrogen fuel generator scheme, the source of the hydrogen fuel may be hydrogen generated by the sodium chloride electrolysis alkali process, and in the prior art, the above hydrogen is mostly evacuated. In this way, not only the combined use of resources, but also hydrogen as a clean fuel, but also has the advantage of not polluting the environment. The hydrogen fuel generator scheme can refer to the above scheme of adopting a fuel generator, but the above schemes need to overcome the problem of avoiding noise pollution in densely populated areas.
