Description
Technical Field
The invention relates to a kinetic energy recovery power generation device for a railway wagon during braking, in particular to a technology for converting kinetic energy of a vehicle into electric energy during braking.
Background
The most common form of braking for existing railway freight cars is tread braking. During braking, the brake shoes on the brake beam press the wheels tightly under the action of braking force to generate frictional resistance, so that the vehicle stops running. This process is equivalent to converting the kinetic energy of the vehicle while in operation into heat energy to be dissipated in the air. Although the tread brake has simple structure and wide application, the tread brake can only dissipate the kinetic energy of the vehicle during braking, and cannot be effectively utilized.
Disclosure of Invention
Aiming at the problems, the invention discloses a power generation device for recovering braking kinetic energy of a railway wagon. The device can make the induction coil close to the permanent magnet by utilizing the action of the brake beam close to the wheel pair when the vehicle brakes, so that the magnetic force line cuts the induction coil to generate current.
The invention is realized by the following technical scheme:
a power generation facility for railway freight car braking kinetic energy is retrieved, power generation facility installation sets up on freight car bogie, and the bogie includes: the wheel and the axle body of the axle form the wheel pair assembly, and the brake beam, the brake lever and the brake pull rod form the brake device; the method is characterized in that: the axle body of the axle is fixedly provided with a permanent magnet rotating along with the axle, and the brake beam and the permanent magnet are correspondingly and fixedly provided with an induction coil which moves along with the brake beam and is used for generating electricity.
And the energy storage device is arranged on the bogie and is electrically connected with the induction coil through a cable.
The induction coil is arranged above or below the horizontal plane of the permanent magnet on the axle, so that the induction coil and the permanent magnet are in non-contact proximity.
The invention has the beneficial effects that:
1. the energy-saving braking device can convert part of kinetic energy dissipated by the conventional railway wagon into electric energy to be stored and utilized during braking. The method is favorable for developing other vehicle-mounted energy consumption applications of the railway wagon by utilizing the stored electric energy.
2. The energy that is required to be converted into heat energy for dissipation during braking will be reduced and the pressure (or friction) required between the wheel and the brake shoe will be reduced, and therefore the compressed air required to be consumed by the vehicle braking system will also be reduced, reducing energy consumption.
3. The kinetic energy consumed in the braking process can reduce the abrasion between the wheel and the brake shoe, and prolong the service life of the wheel and the brake shoe.
4. The system of the invention has simple structure, easy manufacture and lower cost.
5. The induction coil and the permanent magnet are not contacted in the application process through reasonable spatial layout.

With reference to the attached drawings.
A power generation facility for railway freight car braking kinetic energy is retrieved, power generation facility installation sets up on freight car bogie, and the bogie includes: the wheel assembly comprises a wheel 1 and an axle body 2 which form a wheel pair assembly, and a brake beam 3, a brake lever 7 and a brake pull rod 8 which form a brake device; the axle body 2 is fixedly provided with a permanent magnet 4 rotating along with the axle, and the brake beam 3 and the permanent magnet 4 are correspondingly and fixedly provided with an induction coil 5 moving along with the brake beam 3 and used for power generation.
An energy storage device 6 is arranged on the bogie, and the energy storage device 6 is electrically connected with the induction coil 5 through a cable 10.
The induction coil 5 is arranged above or below the horizontal plane of the permanent magnet 4 on the axle, and the non-contact approach of the induction coil 5 and the permanent magnet 4 is realized. When the induction coil 5 is leaned against the axle with the brake beam 3, it does not contact the permanent magnet 4 on the axle.
As shown in the figure, the permanent magnet 4 is arranged at the axle body 2 of the axle, the induction coil 5 is arranged on the brake beam 3, the energy storage device 6 is arranged at the proper position of the car body or the bogie, and the induction coil 5 and the energy storage device 6 are connected by a cable. The permanent magnet 4 can be assembled on the axle by interference fit through cold pressing, and two semicircles can be adopted to be connected and wrapped on the axle body 2 of the axle through fastening. The induction coil 5 is arranged above or below the permanent magnet 4 through spatial layout, so as to avoid contact. The energy storage device 6 includes a battery and a power supply control system.
As shown in fig. 1, a common rail wagon tread brake mainly comprises a brake beam 3, a brake lever 7, a brake pull rod 8, a fixed fulcrum 9 and the like, wherein brake shoes 3.1 are installed at two ends of the brake beam 3. When the vehicle brakes, the brake beam 3 slides towards two sides until the brake shoe 3.1 is attached to and tightly presses the wheel tread 1.1, and when the brake beam 3 slides towards the middle, the brake shoe 3.1 is separated from the wheel tread 1.1.
As shown in fig. 2, the permanent magnet 4 is mounted on the axle body 2, the induction coil 5 is mounted on the brake beam 3, and the mounting number of the permanent magnet 4 and the induction coil 5 can be adjusted as required. The permanent magnet 4 can be assembled on the axle by interference fit through cold pressing, and two semicircles can be adopted to be connected and wrapped on the axle body 2 of the axle through fastening. The energy storage device 6 is fixedly arranged on fixed structures such as a sleeper beam of the vehicle bogie and comprises a storage battery and a power supply control system.

When the brake beam 3 is released, the induction coil 5 moves away from the permanent magnet 4 on the axle body 2 along with the brake beam, and no current is generated.
