Description

Technical Field

[0001] The present invention relates to the technical field of high-speed rail power supply, and more specifically, to a backup power supply system for high-speed rail transportation. Background Art

[0002] High-speed rail has the advantages of high speed and high punctuality, and is one of the most ideal ways to transport express parcels. However, in order to ensure the monitoring of items inside the high-speed rail during transportation, existing high-speed rail EMUs are generally equipped with backup power supply cabinets to deal with emergencies and ensure that the vehicle monitoring unit, communication unit, and lighting unit can be used normally.

[0003] However, due to the small internal space of the existing high-speed railway, the backup power supply cabinets on the high-speed railway are generally installed in the aisle of the high-speed railway carriage. At the same time, the existing high-speed railway backup power supply cabinets are large in size and the aisle near the power supply cabinets are narrow. When the power supply cabinet needs to be repaired or inspected daily, the cabinet door of the power supply cabinet needs to be opened. However, most of the existing backup power supply cabinets are generally embedded. In order to ensure the aesthetics of the high-speed railway aisle, the surface of the existing backup power supply cabinet door is flush with the inner wall of the high-speed railway aisle. At the same time, most of the existing power supply cabinet doors are hinged to open and close. In this way, when the power supply cabinet door is opened, the cabinet door is blocked by the inner wall of the high-speed railway aisle and can only be opened and closed by 90 degrees, thereby causing a certain obstruction to the high-speed railway aisle, making it inconvenient for people to walk in the aisle.

[0037] See also Figure 1-10 , the present invention provides the following technical solutions:

[0038] Specifically, it refers to a backup power supply system for high-speed rail transportation, including a cabinet 1, in which electrical components 4 are arranged, and multiple lighting components 5 are arranged on the inner walls of the left and right sides of the cabinet 1. Two cabinet doors 2 that seal the inner cavity of the cabinet 1 are arranged on the front of the cabinet 1, and an extendable mechanism 3 is arranged between the cabinet 1 and the opposite sides of the two cabinet doors 2. The extendable mechanism 3 includes a U-shaped seat 31, and a contraction groove 33 is opened on the front of the cabinet 1 close to the U-shaped seat 31. The vertical plate of the U-shaped seat 31 extends into the contraction groove 33 and slides in the contraction groove 33. A rotating shaft 32 is rotatably connected between the upper and lower horizontal plates of the U-shaped seat 31. The side of the cabinet door 2 close to the U-shaped seat 31 extends between the upper and lower horizontal plates of the U-shaped seat 31 and is sleeved on the outer surface of the rotating shaft 32. Therefore, the cabinet door 2 opens and closes with the rotating shaft 32 as the rotation point.

[0039] The upper and lower horizontal plates of the U-shaped seat 31 are both provided with a transmission cavity 34, and the upper and lower ends of the rotating shaft 32 are respectively rotated to penetrate into the two transmission cavities 34, and a disc 35 is provided at one end of the rotating shaft 32 located in the transmission cavity 34, and two push rods 36 are provided on the inner wall of the rear side of the contraction groove 33, and the other end of the push rod 36 slides into the transmission cavity 34, and a sleeve shaft 37 away from the center of the disc 35 is provided on the surface of the side of the disc 35 facing away from the rotating shaft 32, and a first rotating plate 38 is rotatably sleeved on the outer surface of the sleeve shaft 37, and the other side of the first rotating plate 38 is hinged to one end of the push rod 36 located in the transmission cavity 34. When the cabinet door 2 needs to be opened, the cabinet door 2 is opened with a sleeve shaft 37 away from the center of the disc 35. The rotating shaft 32 rotates outward as the rotating point, and the rotating shaft 32 drives the disc 35 to rotate synchronously. Since the sleeve shaft 37 is set at the eccentric position of the disc 35, the sleeve shaft 37 will form a thrust on the first rotating plate 38 during the rotation of the disc 35. At the same time, since the push rod 36 is kept stationary, the first rotating plate 38 will form a reverse thrust on the U-shaped seat 31, so that the U-shaped seat 31 gradually moves out of the contraction groove 33, thereby causing the cabinet door 2 to move to the front side. In this way, when the cabinet door 2 rotates more than 90 degrees, the inner wall of the high-speed railway aisle will not block the cabinet door 2, so that the cabinet door 2 can be rotated to 180 degrees and contact the inner wall of the high-speed railway aisle (see the attached manual). Figure 4 ), the above structure will not occupy the internal space of the cabinet 1 and too much aisle space. It will not affect the maintenance work of the high-speed rail maintenance personnel, nor will it affect other people walking in the aisle. It optimizes the maintenance of the backup power supply system and does not occupy too much internal installation space of the high-speed rail.

[0040] The lighting assembly 5 includes a lighting fixture 51, which is arranged in a cabinet 1. A storage groove 52 adapted to the outer surface of the shell of the lighting fixture 51 is opened on the inner wall of the cabinet 1 near the lighting fixture 51, and a pushing cavity 56 is opened in the side wall of the cabinet 1. Two movable rods 54 are arranged on the surface of the shell of the lighting fixture 51 near the pushing cavity 56. A movable component is arranged between the lighting fixture 51 and the movable rods 54. The other ends of the two movable rods 54 are slid into the pushing cavity 56. A pushing plate 57 is arranged at one end of the two movable rods 54 located in the pushing cavity 56. A second spring 58 movably sleeved on the outer surface of the movable rod 54 is arranged between the pushing plate 57 and the inner wall of the pushing cavity 56. When the second spring 58 is not squeezed, the second spring 58 will form a thrust on the pushing plate 57, so that the lighting fixture 51 shrinks into the storage groove 52.

[0041] A pulling rod 59 is provided on the surface of the U-shaped seat 31 facing the pushing cavity 56, and the other end of the pulling rod 59 slides into the pushing cavity 56, and a pulling rope 511 is provided between the pulling rod 59 and the pushing plate 57. A directional wheel 510 is rotatably connected to the bottom wall of the pushing cavity 56, and the pulling rope 511 is laid on the outer surface of the directional wheel 510 and is transmitted on the outer surface of the directional wheel 510. Therefore, when the U-shaped seat 31 moves out of the contraction groove 33, the U-shaped seat 31 will form a pulling force on the pulling rope 511, so that the pulling rope 511 pulls the pushing plate 57 to move to the side close to the storage groove 52. At this time, the movable rod 54 can push the lighting fixture 51 out of the storage groove 52. The above structure can automatically push the lighting fixture 51 out of the storage groove 52 when the staff opens the cabinet door 2, so as to illuminate the inside of the standby power supply cabinet. There is no need for the staff to check with a flashlight, which makes it more convenient for the staff to check the standby power supply cabinet on the high-speed railway.

[0042] A power source for providing power to the lighting fixture 51 is provided in the storage slot 52, and an infrared switch for controlling the lighting fixture 51 to be turned on is provided in the storage slot 52. Therefore, when the lighting fixture 51 is pushed out of the storage slot 52, the infrared switch turns on the lighting fixture 51, causing the lighting fixture 51 to emit light. When the lighting fixture 51 is retracted into the storage slot 52, the infrared switch turns off the lighting fixture 51.

[0043] The movable component includes a hinged head 53, which is arranged on the surface of the lighting fixture 51 shell near the movable rod 54. A rotating shaft 512 is rotatably connected between the two horizontal plates of the hinged head 53. One end of the movable rod 54 near the hinged head 53 is sleeved on the outer surface of the rotating shaft 512. Therefore, the lighting fixture 51 can rotate on the movable rod 54, so as to adjust the illumination angle of the lighting fixture 51, thereby further improving the lighting effect inside the power supply cabinet.

[0044] A limiting shell 55 is provided on the outer surface of the hinge head 53, and a circular cavity 551 is provided in the limiting shell 55. One end of the rotating shaft 512 close to the limiting shell 55 rotates and penetrates into the circular cavity 551. A contraction cavity 552 is provided in one end of the rotating shaft 512 located in the circular cavity 551. A limiting rod 553 is provided in the contraction cavity 552. One end of the limiting rod 553 slides through the outer surface of the rotating shaft 512 and extends into the circular cavity 551. One end of the limiting rod 553 located in the circular cavity 551 is hemispherical. An anti-slip plate 555 is provided at one end of the limiting rod 553 located in the contraction cavity 552. A second tension spring 556 movably sleeved on the outer surface of the limiting rod 553 is provided between the anti-slip plate 555 and the inner wall of the contraction cavity 552. A plurality of limiting grooves 554 arranged in a circumferential array are provided on the annular inner wall of the circular cavity 551. The limiting groove 554 is adapted to one end of the limiting rod 553 located in the circular cavity 551. When the limiting rod 553 moves into the limiting groove 554, the limiting rod 553 will have a limiting effect on the lighting fixture 51, so that the lighting fixture 51 will not rotate on its own. When the staff needs to adjust the lighting angle of the lighting fixture 51, they only need to press the lighting fixture 51 in the adjustment direction. At this time, the inner wall of the limiting groove 554 will squeeze the limiting rod 553, so that the limiting rod 553 gradually shrinks into the shrinkage cavity 552. At the same time, the second tension spring 556 is stressed and stretched. When the lighting fixture 51 rotates to a specified angle, the limiting rod 553 moves into the limiting groove 554 at a specified position under the pull of the second tension spring 556, thereby completing the angle fixation of the lighting fixture 51, further ensuring the effect of the staff when inspecting the inside of the power supply cabinet.

[0045] A built-in cavity 362 is provided in the upper horizontal plate of the U-shaped seat 31, and the built-in cavity 362 is located at the rear side of the transmission cavity 34. A clamping rod 363 is provided in the built-in cavity 362, and one end of the clamping rod 363 slides through the built-in cavity 362 and contacts the outer surface of the push rod 36. A built-in plate 364 is provided at one end of the clamping rod 363 located in the built-in cavity 362, and a first tension spring 365 movably sleeved on the outer surface of the clamping rod 363 is provided between the built-in plate 364 and the inner wall of the built-in cavity 362. When the clamping rod 363 contacts the outer surface of the push rod 36, the outer surface of the push rod 36 will squeeze the clamping rod 363, so that the initial position of the built-in plate 364 is on the side away from the push rod 36. In addition, the first tension spring 365 is in a stretched state, and a snap-in hole 361 adapted to the snap-in rod 363 is provided on the outer surface of the push rod 36 facing the built-in cavity 362. When the U-shaped seat 31 gradually moves out of the shrinkage groove 33, the snap-in rod 363 slides on the surface of the push rod 36 and gradually approaches the snap-in hole 361. When the cabinet door 2 rotates to one hundred and eighty degrees, the snap-in rod 363 and the snap-in hole 361 are at the same horizontal position, so that the snap-in rod 363 moves into the snap-in hole 361 under the pull of the first tension spring 365, thereby completing the fixation of the U-shaped seat 31 and making the U-shaped seat 31 unable to move. In this way, the firmness of the cabinet door 2 after opening and the stability of the lighting assembly 5 when used are guaranteed.

[0046] A pressing groove 22 is provided on the surface of the cabinet door 2 on the side away from the rotating shaft 32, and a pressing plate 21 is slidably connected in the pressing groove 22. A pushing cavity 25 is provided between the cabinet door 2 and the rotating shaft 32. A pressing rod 23 with one end sliding into the pushing cavity 25 is provided on the surface of the pressing plate 21 facing the pushing cavity 25. A first spring 24 movably sleeved on the outer surface of the pressing rod 23 is provided between the pressing plate 21 and the inner wall of the pressing groove 22. When the first spring 24 is not squeezed, the first spring 24 will squeeze the pressing plate 21 so that the outer surface of the pressing plate 21 is flush with the surface of the cabinet door 2 on the side away from the rotating shaft 32.

[0047] The inside of the disk 35 is hollow, and a push rod 26 is provided in the push cavity 25, and the upper end of the push rod 26 slides through the disk 35. A third rotating plate 27 is hinged between the lower end of the push rod 26 and one end of the pressing rod 23 located in the push cavity 25. The outer surface of the disk 35 is provided with an unlocking protrusion 28 that slides through the outer surface of the disk 35. A fourth rotating plate 29 is hinged between the upper end of the push rod 26 and the unlocking protrusion 28. The initial position of the unlocking protrusion 28 is flush with the outer surface of the disk 35. The bottom wall of the transmission cavity 34 is provided with a support plate 369, and a trigger rod 367 is slidably sleeved on the support plate 369. The front end of the trigger rod 367 contacts the surface of the disc 35. After the cabinet door 2 rotates 180 degrees outward, the front end of the trigger rod 367 contacts the outer surface of the unlocking protrusion 28, and the rear end of the trigger rod 367 slides through the built-in cavity 362. A connecting rod 366 is provided on the surface of the side of the built-in plate 364 facing away from the clamping rod 363. The trigger rod 367 is located at The second rotating plate 368 is hingedly connected between one end of the built-in cavity 362 and the connecting rod 366. When the cabinet door 2 needs to be closed, the staff member presses the pressing plate 21 with his finger, so that the pressing plate 21 shrinks into the pressing groove 22. At the same time, when the pressing plate 21 moves into the pressing groove 22, the pressing rod 23 will form a thrust on the third rotating plate 27, so that the third rotating plate 27 drives the pushing rod 26 to move upward. Therefore, the fourth rotating plate 29 can push the unlocking protrusion 28 out of the disc 35, so that the unlocking protrusion 28 can squeeze the trigger rod 367, so that the trigger rod 367 moves into the built-in cavity 362. At this time, the second rotating plate 368 will form a thrust on the connecting rod 366, so that the clamping rod 363 can be pulled out of the clamping hole 361, so that the clamping rod 363 cannot restrict the pushing rod 36, thereby cannot affect the staff from closing the cabinet door 2. At the same time, the pressing groove 22 can provide the staff member with swinging space for the finger, which makes it easier for the staff to close the cabinet door 2.

[0048] The working principle of a backup power supply system for high-speed rail transportation provided by the present invention is as follows: the first step, when it is necessary to inspect the inside of the high-speed rail distribution cabinet, the staff opens the cabinet door 2, and the cabinet door 2 rotates outward with the rotating shaft 32 as the rotating point, and the rotating shaft 32 simultaneously drives the disc 35 to rotate. Since the sleeve shaft 37 is arranged at the eccentric position of the disc 35, the sleeve shaft 37 will form a thrust on the first rotating plate 38 during the rotation of the disc 35. At the same time, since the push rod 36 is kept stationary, the first rotating plate 38 will form a reverse thrust on the U-shaped seat 31, so that the U-shaped seat 31 gradually moves out of the contraction groove 33, thereby causing the cabinet door 2 to move to the front side. In this way, when the cabinet door 2 rotates more than ninety degrees, the inner wall of the high-speed rail aisle will not block the cabinet door 2, so that the cabinet door 2 can be rotated to one hundred and eighty degrees to contact the inner wall of the high-speed rail aisle;

[0049] Step 2: When the cabinet door 2 is opened, the U-shaped seat 31 will exert a pulling force on the pull rope 511, so that the pull rope 511 pulls the push plate 57 to move toward the side close to the storage slot 52. At this time, the movable rod 54 can push the lighting fixture 51 out of the storage slot 52. With the above structure, when the staff opens the cabinet door 2, the lighting fixture 51 can be automatically pushed out of the storage slot 52 to illuminate the interior of the standby power supply cabinet.

[0050] Step 3: When the cabinet door 2 rotates to 180 degrees, the clamping rod 363 and the clamping hole 361 are at the same horizontal position, so that the clamping rod 363 moves into the clamping hole 361 under the pulling of the first tension spring 365, thereby completing the fixation of the U-shaped seat 31 and making the U-shaped seat 31 unable to move.
