Description

Technical Field

[0001] The utility model belongs to the technical field of railway freight car power generation, in particular to a railway freight car wind power generation device. Background Art

[0002] With the development of economy and the continuous development of demand in express logistics and other industries, my country's railway freight cars are constantly developing in the direction of fast and heavy load. The existing railway freight cars are equipped with a power generation room in the front of the car, which supplies power to the front of the car and the lighting inside the front of the car. The carriages of railway freight cars do not have electricity, because railway freight cars are one carriage fixed to another carriage, and each carriage is equipped with a brake device under it. Most of the existing railway freight cars still use traditional pneumatic brake systems because there is no electricity. The pneumatic brake system does not require the supply of electricity, but problems often occur. Therefore, in order to solve this problem, the railway freight car is equipped with a detection device on the pneumatic brake system to detect whether the pneumatic brake system can be pneumatic normally, especially whether the pneumatic valve is open. If all railway freight cars are converted into fast and heavy-loaded freight cars, the existing pneumatic brake system may need to be changed to a more appropriate electric control brake system. In order to solve the braking problem more safely, the existing railway freight cars are also equipped with anti-skid devices and wheel axle temperature detection devices. In order to achieve effective braking and monitor the wheel axle temperature at all times, it is necessary to equip the railway freight car with a reliable power supply device.

[0003] For railway passenger cars, each carriage is connected with cables and wires, and no additional power supply equipment is needed. However, for railway freight cars, if the carriages are modified to be connected to external wires, it will cost a lot and is not very realistic. In addition, the entire freight railway will also need to be equipped with cables and wires.

[0004] At present, there is a device for generating electricity by cutting magnetic flux lines by rotating the axle of the truck. For the generator that cuts magnetic flux lines by rotating the axle of the truck, the gap between the stator and the rotor is very small, mostly between 1-2mm. Since the railway truck will vibrate and bump during movement, the biggest difficulty is to ensure that the gap between the motor rotor and the stator is constant. Once the gap between the stator and the rotor changes, the stator and the rotor will collide, and the generator cannot work normally.

[0005] To this end, for railway freight cars, an external power generation device can effectively solve the problem of power supply required for the freight car compartments. Utility Model Content

DETAILED DESCRIPTION

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

[0026] like Figure 1-5As shown, a railway freight car wind power generation device includes a power generation device 102, and the power generation device 102 includes a wind power generation device and a stable platform 10. The wind power generation device utilizes the wind power that is inevitably generated when the freight car is running, and converts it into electric energy for use by the freight car's electric device; the stable platform is to prevent the freight car from shaking too much during operation, which causes the entire wind power generation device to fall off easily. Rotating blades are arranged at both ends of the wind power generation device, and the rotating blades are arranged at both ends, which fully meet the requirements of the freight car not turning around and directly changing the direction to move forward. The situation that the other side cannot generate wind power conversion once the freight car turns around and moves forward due to the rotating blades arranged at a single end will not occur. The middle part of the wind power generation device is detachably connected to the stable platform 10, and the stable platform 10 is connected to the bottom of the train freight car compartment 103 through a double-head mounting rod 12; the wind power generation device is connected to the electric device of the train freight car compartment. The electric device of the train freight car compartment includes electric control braking system, anti-skid device, wheel axle temperature detection and other equipment that requires electricity.

[0027] Among them: Figure 1 and 2 As shown, the wind power generation device includes a rotating hub 1, rotating blades 2, a speed increaser 3, a generator 4, a power distribution management system 5, a constant voltage processor 6 and a storage device 7. The rotating blades 2 are fixed on the rotating hub 1, the rotating hub is connected to the speed increaser 3, the speed increaser 3 is connected to the generator 4, the rotor winding outlet end of the generator 4 is connected to the constant voltage processor 6 through a frequency converter, a group of automatic switch groups are set at the rear end line of the constant voltage processor 6, and a group of automatic switch groups are set at the rear end line of the stator winding outlet end of the generator 4. The two automatic switch groups are connected in parallel and connected to the storage device 7.

[0028] The rotating hub 1 is also provided with a blade correction device 13, which mainly prevents the central axis of the rotating blade from deviating too much, thereby causing damage to the blade or the entire wind power generation device.

[0029] like Figure 3 As shown, the front and rear ends of the wind power generation device are respectively provided with rotating blades, and the front and rear ends are air inlet ends, and a dustproof net 14 is provided on the air inlet end. A protective cover 8 is provided on the outside of the wind power generation device, and a mounting frame 9 is provided on the protective cover 8. Figure 4 As shown, the wind power generation device is detachably connected to a mounting plate 11 on a stable platform 10 via a mounting frame 9 .

[0030] like Figure 5 As shown, the double-headed mounting rod 12 is detachably connected to the truck chassis 101 at the bottom of the train truck compartment 103 .

[0031] Among them: the protective cover can prevent dust and debris from entering the motor, and can also prevent the blades from being hit by stones jumping from the railway. When the train is moving, in the case of rain, mud, dust, etc., the protective cover can also reduce the entry of external pollutants, which can reduce the failure of the power generation device and further extend the service life of the power generation device.

[0032] Among them, the stable gimbal is a three-axis anti-shake gimbal, which is connected by axes set in three directions; the axes set in the three directions are respectively the vertical support axis, the curved steering axis and the horizontal axis for adjusting the horizontal position. The three axes are connected by a smooth axis, and the camera shake is balanced by controlling the movement of the three axes. When it is working, when the truck is running, the entire car is bumped, and the stable gimbal fixed on the truck chassis will be affected, but the three-axis anti-shake gimbal will maintain balance through its own adjustment when it is bumped, thereby reducing or eliminating the impact of the truck car bumping on the wind turbine, especially the impact on the blades and the rotating shaft. When the gimbal moves forward, the gimbal bracket will move backward, so that the wind turbine fixed on the entire stable gimbal remains unchanged.

[0033] The power generation device is hinged and fixed to the fixed frame at the bottom of the truck through a stable anti-shake platform. The stable anti-shake platform can maintain the balance and fixation of the entire power generation device through self-balancing adjustment capabilities; it can ensure that the motor position is adaptively adjusted when the truck encounters bumps and vibrations during operation, and the hinge is convenient for installation, disassembly and replacement.

[0034] When the fan is running, the wind acts on the blades, generating a forward thrust, which causes the rotating blades to start rotating, and also rotates with the rotating hub, generating a torque. The rotating hub transmits the kinetic energy of rotation to the drive shaft, which passes through the gearbox, and the gears in the gearbox increase the speed, and then transmits the kinetic energy to the generator, which converts the mechanical energy into electrical energy. The constant voltage processor controls the output power of the wind turbine to adapt to the load changes of the power grid.

[0035] The wind turbine blades convert wind energy into mechanical energy by rotating the blade shaft. The materials of the blades are usually glass fiber reinforced plastic, carbon fiber and polymer. In this embodiment, the blades are made of carbon fiber material, which has the advantages of light weight, reducing the bearing capacity of the stable platform, high strength, corrosion resistance, and can well adapt to various natural conditions of railway freight cars on the running railway. Under the action of wind energy, the deformation and deformation of the blades are very small, and its main movement mode is rotation. The rotation of the blades drives the main shaft to rotate, thereby generating a torque to convert wind energy into electrical energy. Therefore, the loss of the entire motor is relatively small.

[0036] During installation, the installation orientation must be such that the axis of the rotating blades is aligned parallel to the axis of the truck. This way, there is no need to adjust the direction of the wind, because rotating blades are provided at both ends of the wind turbine. Therefore, wind energy can be generated regardless of the direction in which the carriage is moving. Especially after the train truck arrives at the station, when the locomotive is replaced to change the direction of the truck carriage, there is no need to deliberately turn the device because the wind energy can be felt at both ends.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
