Description

Technical Field

[0001] The present invention belongs to the technical field of rail train power generation, and specifically relates to a train flexible self-generating device and a power generation control method. Background Art

[0002] As an efficient and convenient mode of transportation, rail transit has been widely used around the world. The rapid development of the railway system is not only reflected in the field of high-speed railways, but also covers various forms such as urban rail transit and scenic rail trains for tourism. With the popularization of rail transit and the advancement of technology, how to improve the energy efficiency of trains and reduce dependence on external energy supply has become one of the important directions of rail train technology development.

[0003] At present, most rail trains rely on external power grids or onboard battery systems for power supply. However, in certain scenarios such as tourist attractions, the deployment of external power supply systems is inconvenient due to the high cost of laying power grids and strict environmental requirements. Therefore, improving the self-generation capacity of rail trains to meet the energy needs of trains during driving has become an effective solution.

[0004] Most of the current technologies used for train self-generation focus on kinetic energy recovery and braking energy reuse. During train operation, especially during the braking phase, the train's kinetic energy is often converted into heat energy and wasted. Although some technologies have attempted to convert the kinetic energy during braking into electrical energy through energy recovery devices, existing devices have problems such as complex structure, low efficiency, and high maintenance costs. In addition, the long-term operation of energy recovery devices may cause damage to the tracks.

[0005] At the same time, the existing rail train kinetic energy recovery technology is mostly used in high-speed railway systems and has not been widely used in scenic sightseeing trains. Scenic rail trains are usually small in size, light in body, and run at a low speed, which makes it difficult to effectively apply the existing power generation technology on scenic rail trains.

[0011] In one implementation of the above device, a ball is fixedly sleeved on the outer side of the main shaft, and a spherical rubber jacket is sleeved on the ball.

[0012] In one embodiment of the above device, the shell is a hollow high-strength rectangular box with an open front and a semi-open top.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the relevant technical solutions. Obviously, the described embodiments are only part of the embodiments, 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.

[0033] like Figure 1 As shown, the flexible self-generating device for train disclosed in this embodiment includes an upper mounting seat 1, a swing arm rod 2, a linear telescopic rod 3, a connecting column 4, a shell 5 and a power generation assembly 6.

[0034] like Figure 2 As shown, the upper mounting seat 1 is a hinged ear seat, which is detachably fixed to the bottom plate of the two side beams of the rail train bogie by high-strength bolts.

[0035] The swing arm member 2 is composed of two swing arm members, the upper part of which hinges and clamps the upper mounting seat; and the lower part of which hinges and clamps the connecting column 4.

[0036] The linear telescopic rod 3 connects and fixes the rail vehicle bogie and the swing arm member 2, and the linear telescopic rod can be extended or contracted under external drive.

[0037] The housing 5 is a hollow high-strength rectangular box with an open front and a semi-open top. Three connecting columns 4 are arranged at fixed intervals on the top of the housing, and each connecting column is connected to a swing arm rod 2 and an upper mounting seat 1.

[0038] like Figure 3 As shown, the power generation assembly 6 includes a main rotating shaft 61, a transverse rotating shaft 62, a shock absorbing spring 63, a rotor 64, a rotating shaft sleeve 65, a vertical rotating shaft 66, a stator winding 67, a gear 68 and a piezoelectric beam 69.

[0039] A ball bearing is fixedly sleeved on the outer side of the main rotating shaft 61, and a spherical rubber sleeve is sleeved on the ball bearing, which greatly reduces the wear on the rail surface. At the same time, it can stably exert the self-generating effect while ensuring the safety of driving.

[0040] The inner side of the main rotating shaft 61 is connected with a transverse rotating shaft 62 along the length direction, and the end of the transverse rotating shaft is connected to the housing. The transverse rotating shaft is a telescopic sleeve rod, and a shock absorbing spring 63 is arranged on the outer side thereof to support the main rotating shaft.

[0041] like Figure 4As shown, a cylindrical rotor 64 is arranged in the middle of the main shaft 61, and the rotor will rotate along with the rotation of the main shaft.

[0042] The main shaft 61 is provided with a shaft sleeve 65. The bottom end of the shaft sleeve is fixedly connected with a vertical shaft 66 along the vertical direction, and the end of the vertical shaft is connected to the bottom end of the housing. The vertical shaft is a telescopic sleeve rod, and a shock absorbing spring 63 is arranged on the outside to support the shaft sleeve.

[0043] A shaft sleeve 65 is also sleeved outside the vertical shaft.

[0044] like Figure 5 As shown, the inner surface of the shaft sleeve 65 outside the main shaft is fitted with a stator winding 67. The stator winding is arranged on the shaft sleeve at an angle of 2 / 3π of the circumferential phase difference.

[0045] Since the rotor is a magnet and the stator winding is a conductor, the moving path of the rotor intersects with the direction of the magnetic field; when the main shaft drives the stator and rotor to rotate, it will cut the magnetic flux lines to form current, and the current will flow into the collector assembly in the shell through the main shaft and the transverse shaft.

[0046] like Figure 6 As shown, a cylindrical gear 68 is fixedly arranged behind the main shaft 61, and piezoelectric beams 69 arranged in a circumferential form are arranged behind the gear. The front end of the piezoelectric beam contacts the edge of the gear, and the rear end of the piezoelectric beam is inserted into the collector assembly of the shell.

[0047] When the gear rotates continuously with the main shaft, the piezoelectric beam will be continuously moved by the gear to generate a stable potential difference. This part of the potential difference energy flows into the collector assembly through the line.

[0048] Six groups of power generation components 6 are evenly arranged at fixed intervals in the inner cavity of the housing 5. The rotating shaft sleeves of adjacent power generation components are connected and limited to each other by limiting rods.

[0049] like Figure 7 As shown, when the device is used for self-generation, it is necessary to first fix the four upper mounting seats on the bottom plates of the beams on both sides of the rail train bogie corresponding to the positions on both sides of the two rails, and then connect the swing arm rod, linear telescopic rod, connecting column, shell and power generation assembly in sequence; then drive the linear telescopic rod to make the ball of the power generation assembly in close contact with the bottom surface of the rail; when the train starts, the ball will rotate in the opposite direction of the train, and at the same time drive the main shaft to rotate to generate electricity.

[0050] A plurality of self-generating devices are arranged at fixed intervals on each carriage of a rail train.

[0051] A control method for self-generating electricity using the device, the steps of which are as follows:

[0052] 1. Multiple devices are installed at fixed intervals on each carriage of a rail train.

[0053] 2. Obtain the power status of electrical equipment in each carriage of the rail train and the driving status of the rail train.

[0054] 3. Make judgments based on the data obtained in step 2 and adjust the status of the device.

[0055] 4. When the train brakes, it is in full power generation state, and the linear telescopic rods that drive all devices bring the balls of the power generation components into close contact with the ground of the rails, so as to make full use of the huge kinetic energy when the train brakes.

[0056] 5. When the train accelerates or travels at a constant speed, it is in a low-power power generation state. At this time, the power of the electrical equipment on each carriage is judged. For the carriage with less than one-third of the power, the drive device charges the electrical equipment on the carriage; for the carriage with more than one-third of the power, the ball bearings of the device are separated from the rails to avoid energy loss caused by normal power generation, while extending the service life of the device and reducing maintenance costs.

[0057] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although detailed descriptions have been made with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
