Description

Technical Field

[0001] The present invention belongs to the field of electromechanical technology, and relates to a mechatronic product for storing the vibration energy of railway tracks. It can be used for storing, transporting, and converting the vibration energy of tracks in the fields of railway and urban rail transit. In particular, it relates to a method and device for storing the vibration energy of tracks. Background Art

[0002] At present, the new energy power generation technologies in China mainly utilize renewable energy sources including solar energy, biomass energy, wind energy, geothermal energy, wave energy, ocean current energy, and tidal energy, and realize the power generation process through existing technologies. However, for rail transit, which has geographical environments such as mountains, plains, plateaus, rivers, lakes, and seas, as well as engineering environments such as tunnels, bridges, and underground special areas, the long and narrow space with complex environments makes it difficult to find new energy power generation methods suitable for various environments. The only common feature is that the trains passing through the tracks generate huge vibration energy, which has high utilization value. However, the running time of trains is short and the energy is large. In addition, railway tracks involve personal safety factors, and the space around the tracks is narrow. Therefore, it is relatively difficult to collect, store, and convert and utilize the vibration energy of the tracks. If the vibration energy of the tracks can be converted from one form to another and stored for release and utilization in a limited space, it will greatly change our view of renewable energy and actively take all means to utilize it.

[0003] Air, as a common medium around us, occupies a certain space but has no fixed shape and volume. When pressure is applied to the air in a closed container, the volume of the air is compressed, increasing the internal pressure. When the external force is removed, the air will return to its original volume under the action of the internal pressure. If there is a movable object in the container, when the air returns to its original volume, the object will be pushed out by the pressure of the air in the container. This principle is widely used in production and life. Compressed air is the second largest power energy after electricity and is also a process gas source with various uses. Its application scope covers industries and departments such as petroleum, chemical industry, metallurgy, electric power, machinery, light industry, textile, automobile manufacturing, electronics, food, medicine, biochemistry, national defense, and scientific research. Whether it is a ballast bed or a ballastless bed for railway tracks, the space from the bottom of the track to the bed is relatively small, and it is basically impossible to install equipment. Summary of the Invention

[0039] The principle of the track vibration energy storage unit array of the present invention is as Figure 2 shown:

[0040] The array of track vibration energy storage units consists of multiple compressed air storage units 4 and pneumatic generators arranged in sequence beside the track, and the number thereof can be combined according to actual power supply requirements.

[0041] When the train passes by, the track vibration is converted into compressed air by the air compression unit for storage. The multiple air compression units 31 arranged in an array along the track are conducive to the conversion and convergence of energy, can quickly fill the air storage tank 42 to improve the storage efficiency, and are also easy to maintain and manage.

[0043] The compressed air storage unit 4 includes: an air storage tank intake valve 41, an air storage tank 42, an air storage tank base 43, an air storage tank exhaust overflow valve 44, and an air storage tank exhaust check valve 45; the air storage tank intake valve 41 is fixedly connected to the air storage tank 42; the air storage tank 42 is respectively fixedly connected to the air storage tank base 43 and the air storage tank exhaust overflow valve 44; the air storage tank exhaust overflow valve 44 is connected to the air storage tank exhaust check valve 45 and the pneumatic power generation device 5 in sequence through a trachea.

[0044] As Figure 5As shown in the figure, the pneumatic power generation device 5 includes: turbine A, turbine B, turbine C, and turbine D. The intake hole 51 of turbine A is connected to the exhaust hole 53 of turbine A through an air duct; the intake hole 52 of turbine B is connected to the exhaust hole 54 of turbine B through an air duct; the intake hole 55 of turbine C is connected to the exhaust hole 56 of turbine C and the intake air duct 59 of turbine C respectively through an air duct; the intake hole 57 of turbine D is fixedly connected to the exhaust hole 58 of turbine D and the intake air duct 510 of turbine D respectively through an air duct; turbine A511, turbine B512, turbine C513, and turbine D514 are fixedly connected to the turbine shaft 515; the rotor 517 of the pneumatic power generation device is fixedly connected to the turbine shaft 515 through the pneumatic power generation device bearings 516 at both ends; the stator 518 of the pneumatic power generation device is fixedly connected to the motor housing 519.

[0045] The control principle of the track vibration energy storage system of the present invention is as Figure 3 shown:

[0046] Before the train passes through the track vibration energy storage system, the vibration sensing unit 7 triggers an instruction through vibration acceleration to notify the controller 2 of the information about the approaching train and its traveling direction. The controller 2 controls the opening or closing of the air storage tank intake valve 41 of the air compression unit 31 to control whether it stores air, and transmits the control information to the monitor 1 for monitoring.

[0047] When the train passes through the track vibration energy storage system, the air compression unit 31 uses the vertical vibration displacement of the track to push the cylinder piston 319 to compress air, and continuously transports it to the air storage tank 42. The air storage tank 42 stores air; the controller 2 controls the opening or closing of the charging switch of the battery pack 6 to control whether the battery pack 6 is charged. The air convection caused when the train passes through flows through the intake air duct into the turbine chamber to push the turbine to rotate, and flows out from the exhaust port. The pneumatic generator charges the battery pack 6.

[0048] When the train leaves the track vibration energy storage system, the controller 2 controls whether the exhaust valve of the compressed air storage unit 4 releases compressed air for power generation and whether the battery pack 6 is charged; when the compressed air storage unit 4 is filled with gas, the air storage tank 42 of the compressed air storage unit 4 waits to be taken out and replaced with an empty air storage tank 42.

[0049] When the data of the controller 2 is abnormal, the monitor 1 stops the controller 2 manually, and the excess gas transported by the air compression unit 31 will overflow through the overflow valve of the compressed air storage unit 4.

[0050] Refer to Figure 4As shown in the figure, the vibration energy storage principle is as follows: When the train approaches the area of the compressed air storage unit array 3 and the track vibration reaches the trigger value of the vibration sensing unit 7, the trigger activates the controller 2 to turn on the air storage mode and the charging mode; When the train passes through the area of the compressed air storage unit array 3, a large displacement is generated in the vertical direction at the bottom of the track 310 between the two sleepers. When the track 310 vibrates, it causes the buffer device 311 to vibrate and generate vertical vibration and displacement. The buffer device 311 is equipped with a spring with a large stiffness inside. When the spring vibrates, it will filter out some high-frequency vibrations, and the energy utilization rate is the highest during low-frequency resonance; When the track 310 moves downward, the vertical displacement of the buffer device 311 drives the connecting rod 312 fixedly connected to it to rotate counterclockwise around the connecting rod rotating shaft 314 with the connecting rod bracket 316 as the support; After the connecting rod 312 rotates, it drives the piston rod 315 rotatably connected to it to rotate around the piston rod rotating shaft 313, and the piston rod 315 drives the cylinder piston 319 to slide downward along the cylinder wall 317 to compress the air; The compressed air enters the compressed air storage unit 4 through the cylinder exhaust valve 320, the cylinder exhaust check valve 325, and the air storage tank inlet valve 41 for storage. When the pressure of the compressed air reaches the storage upper limit, the excess gas conveyed by the air compression unit 31 will overflow through the overflow valve of the compressed air storage unit 4; When the track 310 moves upward, the return spring 318 pulls the cylinder piston 319 to slide upward along the cylinder wall 317, and the air flows into the lower chamber of the cylinder through the cylinder inlet check valve 324 and the cylinder inlet valve 321. At the same time, the cylinder piston 319 uses the piston rod 315 to push the connecting rod 312 to rotate clockwise around the connecting rod rotating shaft 314 with the connecting rod bracket 316 as the support, pressing the buffer device 311 tightly against the bottom of the track 310.

[0051] As Figure 5As shown in the figure, the principle of the pneumatic power generation device 5 is as follows: The compressed air storage unit 4 discharges compressed air from the air storage tank exhaust overflow valve 44 through an air pipe. The compressed air flows into the turbine A air inlet hole 51 and the turbine B air inlet hole 52 of the pneumatic power generation device 5 through the air storage tank exhaust check valve 45. At the same time, the compressed air pushes the turbine A 511 and the turbine B 512 to rotate in the same direction. The turbine A 511 and the turbine B 512 drive the turbine shaft 515 to rotate. After the compressed air pushes the turbine A 511 and the turbine B 512 to do work, the energy is released and flows out of the pneumatic power generation device 5 from the turbine A exhaust hole 53 and the turbine B exhaust hole 54 respectively along the flow channel. The middle section of the turbine shaft 515 rotates in the cavity of the motor stator 518 together with the motor rotor 517 under the limit and support of the two pneumatic power generation device bearings 516, and the pneumatic power generation device 5 generates electricity and outputs it to the outside. When the train passes through the track, it will cause the surrounding air to flow rapidly along the running direction. The rapidly flowing air will be captured by the turbine C air inlet channel 59 or the turbine D air inlet channel 510 of the pneumatic power generation device 5 (the installation structures of the turbine C air inlet channel 59 and the turbine D air inlet channel 510 are one facing the running direction of the train and the other facing away from the running direction of the train), enter the cavities of the turbine C 513 or the turbine D 514, push the turbine C 513 or the turbine D 514 to rotate and boost pressure, assist the turbine A 511 and the turbine B 512 to generate electricity or generate electricity by itself and output it to the outside.

[0052] When the train leaves the area of the compressed air storage unit array 3, the controller 2 controls the air storage tank exhaust overflow valve 44 of the compressed air storage unit 4 to open to release compressed air into the pneumatic power generation device 5 for power generation. At the same time, the controller 2 controls the battery pack 6 to turn on the charging mode. When the train leaves the area of the compressed air storage unit array 3, the controller 2 controls the air storage tank exhaust overflow valve 44 of the compressed air storage unit 4 to close so that compressed air cannot enter the pneumatic power generation device 5 for power generation. At the same time, the controller 2 controls the battery pack 6 to turn off the charging mode.

[0053] When the gas pressure of the compressed air storage unit 4 reaches the upper limit, that is, when the air storage tank 42 is full of gas, the air storage tank 42 of the compressed air storage unit 4 waits to be taken out and replaced with an empty air storage tank 42. It is also possible to transfer the compressed gas to the standard air storage tank 42 through the docking air storage tank exhaust overflow valve 44 on site and then transport it.

[0054] When the battery pack 6 is fully charged or reaches the upper limit, the controller 2 prompts the monitor 1 for battery transfer or supplies power to the designated power grid around. The monitoring personnel instruct the controller 2 to close the charge and discharge channels of the battery pack 6 through the monitor 1. The maintenance personnel go to the site to take out the fully charged battery pack 6 and replace it with a new empty battery pack 6 for charging.

[0055] When the data of controller 2 is abnormal, monitor 1 stops controller 2 manually. At this time, the excess gas delivered by air compression unit 31 will overflow through the air storage tank exhaust overflow valve 44 of compressed air storage unit 4.

[0056] Referring Figure 3 and Figure 6 to

[0057] and

[0058] , the present invention relates to a method and device for storing energy of track vibration, including monitor 1, controller 2, air compression unit 31, compressed air storage unit 4, pneumatic power generation device 5, battery pack 6, and vibration sensing unit 7. Monitor 1 is connected to controller 2 through a network to monitor the operation of controller 2; vibration sensing unit 7 is connected to controller 2 through a network to trigger the output of controller 2 instructions; air compression unit 31 is connected to compressed air storage unit 4 through an air pipe; controller 2 is respectively connected to the air storage tank 42 in compressed air storage unit 4 and battery pack 6 through cables. On the one hand, it controls the storage or release of compressed air in compressed air storage unit 4; on the other hand, it controls the charging or discharging of battery pack 6; compressed air storage unit 4 is connected to pneumatic power generation device 5 through an air pipe to deliver compressed air; pneumatic power generation device 5 is connected to battery pack 6 through a cable to realize the energy storage of track 310 vibration energy. The specific steps include:

[0059] Step 1, when the train approaches the area of compressed air storage unit array 3 and the track vibration reaches the trigger value of vibration sensing unit 7, vibration sensing unit 7 triggers controller 2 to turn on the air storage mode and charging mode;

[0060] Step 2, controller 2 queries the numbers, statuses, and power levels of the air storage tanks 42 in compressed air storage unit 3 and battery pack 6, and judges whether air storage and charging are required based on the pressure of air storage tank 42 and the power level of battery pack 6:

[0061] (2a) When controller 2 judges that the statuses of air storage tank 42 and battery pack 6 are abnormal or air storage and charging are not required, controller 2 closes the cylinder intake valve 321 of the air storage tank 42 with this number and the charging channel of battery pack 6;

[0060]

[0061]

[0062] When the controller 2 can only determine that the air storage tank 42 is normal, and air storage is required while charging is not needed, the controller 2 opens the intake valve according to the air pressure in the air storage tank 42 and closes the charging channel;

[0063] When the controller 2 can only determine that the state of the battery pack 6 is normal, and air storage is not needed while charging is required, the controller 2 selects to open the charging channel according to the saturation level of the battery pack 6 and closes the intake valve;

[0064] In the third step, when the train passes through the track vibration energy storage system, the air compression unit 31 uses the vertical vibration displacement of the track 310 to push the cylinder piston 319 to compress air, and continuously delivers it to the air storage tank 42 for air storage in the air storage tank 42;

[0065] When the pressure of the air storage tank 42 of the compressed air storage unit 4 reaches the upper limit, the controller 2 opens the air storage tank exhaust overflow valve 44;

[0066] When the controller 2 has no instruction or is abnormal, the air storage tank exhaust overflow valve 44 automatically discharges compressed air to relieve pressure;

[0067] In the fourth step, the controller 2 controls the air storage tank exhaust overflow valve 44 of the compressed air storage unit 4 to open;

[0068] Release compressed gas to the corresponding pneumatic power generation device 5, and the pneumatic power generation device 5 operates and supplies power to the battery pack 6 with the specified number by the controller 2;

[0069] When the strong airflow caused by the passing of the train flows through the intake duct of the pneumatic power generation device 5 into the turbine chamber to push the turbine to rotate and flows out from the exhaust port of the turbine chamber, the pneumatic power generation device 5 operates and supplies power to the battery pack 6;

[0070] In the fifth step, the controller 2 closes the air storage tank exhaust overflow valve 44 of the compressed air storage unit 4;

[0071] When the strong airflow caused by the passing of the train flows through the intake duct of the pneumatic power generation device 5 into the turbine chamber to push the turbine to rotate and flows out from the exhaust port of the turbine chamber, the pneumatic power generation device 5 operates and supplies power to the battery pack 6 with the specified number by the controller 2;

[0072] When the strong airflow caused by the passing of the train flows through the intake duct of the pneumatic power generation device 5 into the turbine chamber to push the turbine to rotate and flows out from the exhaust port of the turbine chamber, the pneumatic power generation device 5 idles and does not supply power to the battery pack 6;

[0073] In the sixth step, when the train moves away from the compressed air storage unit array 3 area and the vibration of the track 310 is lower than the trigger value of the vibration trigger;

[0074] (6a) The controller 2 shuts down the gas storage mode of the compressed air storage unit 4 and the charging mode of the battery pack 6;

[0075] (6b) The controller 2 shuts down the gas storage mode of the compressed air storage unit 4, maintains the charging mode of the battery pack 6, and executes step 4a;

[0076] In the seventh step, when the gas pressure of the compressed air storage unit 4 reaches the upper limit, that is, when the gas storage tank 42 is full of gas, the controller 2 prompts the monitor 1 to transfer the gas storage tank 42 or transfer the compressed air;
