Detailed implementation manners
[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0025] Please refer to Figures 1 to 11, the utility model provides a technical solution: a prefabricated substation, including a box body 1 and a box door 2 hinged to the box body 1. A U-shaped block 3 is fixedly connected to the box body 1. A sliding rod 5 is provided on one side of the U-shaped block 3. A sliding sleeve 4 is movably arranged outside the sliding rod 5. The sliding sleeve 4 can not only slide outside the sliding rod 5 but also rotate outside the sliding rod 5. A plurality of grooves 22 are arranged inside the sliding sleeve 4 at equal intervals in a ring shape. A plurality of protrusions 21 matching the grooves 22 are arranged outside the sliding sleeve 4. When the grooves 22 and the protrusions 21 are engaged, the sliding sleeve 4 cannot rotate, so that the cross bar 6 cannot rotate either. The cross bar 6 blocks the rotation of the box door 2, avoiding the box door 2 from closing under the action of wind and causing injury to maintenance personnel. A cross bar 6 is arranged outside the sliding sleeve 4, and a blocking plate can also be installed outside the cross bar 6 to block the through groove 7. The blocking plate is located inside the box door 2 and does not affect the movement of the cross bar 6. A lock box 13 is installed outside the box door 2. A rotating shaft 12 is rotatably installed on the lock box 13. One end of the rotating shaft 12 is rotatably connected to a handle 9. The handle 9 facilitates the staff to rotate the rotating shaft 12. When the box door 2 needs to be opened, rotate the handle 9 to make the rotating shaft 12 rotate. The rotating shaft 12 makes the rotating plate 18 rotate through the square part 20. The rotating plate 18 drives the connecting block 17 to rotate. Since the connecting block 17 is rotatably connected to the lock rod 16 and the lock rod 16 is restricted by the limiting piece 15 and cannot rotate, the lock rod 16 moves under the action of the connecting block 17. The two lock rods 16 move closer to each other. The two ends of the lock rod 16 retract to the inside of the box door 2. The lock rod 16 is no longer blocked by the box body 1. When the lock rod 16 moves, it will also drive the cross bar 6 to move. The cross bar 6 makes the sliding sleeve 4 move, and the groove 22 and the protrusion 21 are separated, so that the locking of the box door 2 can be released and the box door 2 can be opened. The other end of the rotating shaft 12 is provided with a square part 20. A rotating plate 18 is installed outside the square part 20. A square groove 19 matching the square part 20 is opened in the middle of the rotating plate 18. The two ends of the rotating plate 18 are respectively rotatably connected to a connecting block 17. The lock rods 16 are symmetrically arranged inside the box door 2. When the box door 2 is closed, the lock rods 16 are used to fix the box door 2. The end of the connecting block 17 far from the rotating plate 18 is rotatably connected to the lock rod 16. One end of the cross bar 6 is fixedly connected to one of the lock rods 16.
[0026] Wherein, the hinge part between the box door 2 and the box body 1 is on the same axis as the sliding rod 5. When the box door 2 rotates to open or close, the box door 2 rotates around the hinge part between the box door 2 and the box body 1 as the center of the circle. When the sliding sleeve 4 rotates, the cross bar 6 rotates around the sliding rod 5 as the center of the circle. Therefore, making the hinge part between the box door 2 and the box body 1 and the sliding rod 5 on the same axis enables the box door 2 and the cross bar 6 to rotate smoothly without interference between them.
[0027] Wherein, a through groove 7 is provided through the box door 2. The through groove 7 is used to avoid the cross bar 6 and prevent the cross bar 6 from being blocked by the box door 2 during movement.
[0028] Among them, multiple limit plates 15 are fixedly connected to the inner side of the box door 2, and the locking rod 16 is slidingly connected to the adjacent limit plates 15. The limit plates 15 are used to limit the locking rod 16, making the locking rod 16 more stable during movement and preventing the locking rod 16 from deflecting under the action of the connecting block 17.
[0029] Among them, a card block 10 is fixedly connected to the inner side of the lock box 13, and a card slot 11 that matches the card block 10 is penetrated through the handle 9. The card block 10 and the card slot 11 are used to fix the handle 9.
[0030] Among them, a baffle 8 is rotatably installed on one side of the lock box 13. The baffle 8 is used to cover the lock box 13 to prevent external impurities from entering the lock box 13. A magnet 14 is provided on the inner side of the lock box 13. The baffle 8 is made of iron. The magnet 14 is used to adsorb the baffle 8, thereby fixing the baffle 8.
[0031] Specifically, when it is necessary to open the box door 2 for inspection, open the baffle 8, bend the handle 9 downward to separate the card slot 11 from the card block 10, rotate the handle 9 to a horizontal state, and then rotate the handle 9 to rotate the shaft 12. The shaft 12 rotates the rotating plate 18 through the square portion 20, and the rotating plate 18 drives the two connecting blocks 17 to move. The connecting blocks 17 make the two locking rods 16 move closer to each other, and the two ends of the locking rod 16 retract to the inner side of the box door 2. The locking rod 16 is no longer blocked by the box body 1, and the locking rod 16 also drives the cross bar 6 to move. The cross bar 6 moves the sliding sleeve 4, and the groove 22 is separated from the ridge 21. At this time, the sliding sleeve 4 can rotate normally, and the lock of the box door 2 can be released, and then the door can be opened. Open the box door 2. When the box door 2 is opened to a suitable angle, turn the handle 9 to reset and rotate the handle 9, thereby resetting the two locking rods 16. The locking rod 16 drives the cross bar 6 to reset, and the cross bar 6 drives the sliding sleeve 4 to move. The groove 22 in the sliding sleeve 4 engages with the ridge 21, so that the sliding sleeve 4 cannot rotate, thereby locking the box door 2, thereby preventing the box door 2 from closing under the action of wind and causing injury to maintenance personnel. Finally, bend the handle 9 upwards to engage the slot 11 with the block 10 to fix the handle 9, thereby preventing the locking rod 16 from moving under gravity or external action, causing the sliding sleeve 4 to separate from the ridge 21 and lose the locking effect on the box door 2.
