Description

Technical Field

[0001] This utility model belongs to the technical field of prefabricated substations, specifically a vehicle-mounted emergency prefabricated substation. Background Technology

[0002] Prefabricated substations, also known as box-type substations, are highly integrated complete sets of power distribution devices. They cleverly combine high-voltage switchgear, transformers, and low-voltage switchgear into one or more enclosures. This type of substation has a compact structure and occupies a significantly smaller area than traditional substations, effectively saving space resources. It is particularly suitable for urban areas with limited space. Vehicle-mounted emergency box-type substations integrate the functions of box-type substations onto a vehicle. Their biggest advantage is their high mobility. In the event of a sudden power outage, such as a large-scale power outage caused by a natural disaster, or in emergency tasks such as disaster relief, vehicle-mounted emergency box-type substations can be quickly deployed and put into operation to restore power supply in a timely manner, providing strong power support for social stability and the normal operation of production and life.

[0003] The existing vehicle-mounted emergency prefabricated substations have the following shortcomings: They are inconvenient to debug and install. Due to the high chassis of the vehicles, the substation doors are high off the ground, requiring workers to use ladders to climb and open the doors for debugging and cable installation. Since existing vehicle-mounted emergency prefabricated substations do not come with ladders, workers need to carry them separately, increasing manpower. Furthermore, hastily moving ladders on-site can delay the debugging and installation process. In the event of an emergency power demand, preparations cannot be completed in a timely manner, significantly reducing emergency response efficiency. Utility Model Content

[0004] To overcome the above-mentioned shortcomings, this utility model provides a vehicle-mounted emergency box-type substation, which solves the problem that existing vehicle-mounted emergency box-type substations are inconvenient to debug and install.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vehicle-mounted emergency box-type substation, comprising a substation box body, a fixing component provided on one side of the substation box body, a guide rail fixedly connected to one side of the substation box body, a movable frame slidably connected to the guide rail, a ladder rotatably connected to the movable frame, a protective cover and a connecting block fixedly connected to one side of the substation box body respectively, a connecting shaft rotatably connected to the protective cover, a pair of connecting blocks coaxially fixedly connected to the connecting shaft, a box door fixedly connected to one side of each pair of connecting blocks, the top of the connecting shaft fixedly connected to the connecting block, and a transmission component provided on the protective cover.

[0006] As a further embodiment of this utility model: the fixing component includes a second protective cover, which is fixedly connected to one side of the substation box. A servo motor is fixedly connected to one side of the second protective cover. The output end of the servo motor passes through the second protective cover and is rotatably connected to it. A bidirectional threaded rod is coaxially fixedly connected to the output end of the servo motor. A pair of nuts are threaded onto the bidirectional threaded rod, and an L-shaped fixing block is fixedly connected to each nut.

[0007] As a further embodiment of this utility model: a through groove is provided on the side of the protective cover away from the substation box, and the through groove is adapted to the L-shaped fixing block.

[0008] As a further embodiment of this utility model: the transmission assembly includes a worm gear and a support block. The worm gear is coaxially and fixedly connected to the bottom of the connecting shaft. The support block is fixedly connected to an inner wall of the protective cover. A worm is rotatably connected to the support block. The worm meshes with the worm gear. A gear is coaxially and fixedly connected to one end of the worm.

[0009] As a further embodiment of this utility model: a cylindrical rack is fixedly connected to the side of the movable frame near the protective cover, and the cylindrical rack meshes with a gear.

[0010] As a further embodiment of this utility model: both sides of the protective cover are provided with through holes, which are adapted to the cylindrical rack.

[0011] As a further embodiment of this utility model, a pair of limiting blocks are fixedly connected to the side of the guide rail away from the substation box.

[0022] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0023] like Figures 1-5 As shown, this utility model provides a technical solution:

[0024] A vehicle-mounted emergency box-type substation includes a substation enclosure 1. A fixing assembly is provided on one side of the substation enclosure 1. A guide rail 2 is fixedly connected to one side of the substation enclosure 1. A movable frame 3 is slidably connected to the guide rail 2. A ladder 4 is rotatably connected to the movable frame 3. A protective cover 5 and a connecting block 6 are fixedly connected to one side of the substation enclosure 1. A connecting shaft is rotatably connected to the protective cover 5. A pair of connecting blocks 7 are coaxially fixedly connected to the connecting shaft. A door 8 is fixedly connected to one side of each pair of connecting blocks 7. The top of the connecting shaft is fixedly connected to the connecting block 6. A transmission assembly is provided on the protective cover 5. The fixing assembly can vertically fix the ladder 4, so that the ladder 4 is stored vertically on one side of the substation enclosure 1. The ladder 4 is stable and does not shake, and will not be damaged by bumps and collisions during vehicle travel, ensuring transportation safety. When arriving at the emergency site, the staff can quickly unlock the fixing components and lower the ladder 4 to carry out operations, which greatly shortens the preparation time and improves the efficiency of emergency response. After the ladder 4 is lowered, the ladder 4 drives the moving frame 3 to slide on the guide rail 2 to the appropriate position below the box door 8. The relevant components on one side of the moving frame 3 drive the transmission components inside the protective cover 5 to work, so that the connecting shaft on the protective cover 5 rotates. The connecting shaft drives the box door 8 to open through the connecting block 7, so that the box door 8 opens just as the staff pushes the ladder 4 into place, without the need to operate the box door 8 separately, which greatly saves time and effort.

[0025] The fixing assembly includes a second protective cover 9, which is fixedly connected to one side of the substation box 1. A servo motor 10 is fixedly connected to one side of the second protective cover 9. The output end of the servo motor 10 passes through the second protective cover 9 and is rotatably connected to it. A bidirectional threaded rod 11 is coaxially fixedly connected to the output end of the servo motor 10. A pair of nuts 12 are threadedly connected to the bidirectional threaded rod 11. An L-shaped fixing block 13 is fixedly connected to each nut 12. When the ladder 4 is vertical, one side of the ladder 4 is close to the second protective cover 9. The L-shaped fixing blocks 13 hook and fix the two support rods of the ladder 4 respectively. When the ladder 4 needs to be released, the servo motor 10 is started. The output end of the servo motor 10 drives the bidirectional threaded rod 11 to rotate. The bidirectional threaded rod 11 drives the pair of nuts 12 to move closer to each other, so that the L-shaped fixing blocks 13 move away from the corresponding support rods of the ladder 4, and the ladder 4 is released.

[0026] A through groove is provided on the side of the protective cover 2 9 away from the substation box 1. The through groove is adapted to the L-shaped fixing block 13. The L-shaped fixing block 13 slides in the through groove on the protective cover 2 9, effectively preventing the nut 12 from rotating with the bidirectional threaded rod 11.

[0027] The transmission assembly includes a worm gear 14 and a support block 15. The worm gear 14 is coaxially fixedly connected to the bottom of the connecting shaft, and the support block 15 is fixedly connected to the inner wall of the protective cover 5. A worm 16 is rotatably connected to the support block 15. The worm 16 meshes with the worm gear 14. A gear 17 is coaxially fixedly connected to one end of the worm 16. A cylindrical rack 18 is fixedly connected to the side of the moving frame 3 near the protective cover 5. The cylindrical rack 18 meshes with the gear 17. The cylindrical rack 18 moves together with the moving frame 3. The cylindrical rack 18 drives the gear 17 to rotate. The gear 17 drives the worm 16 on the support block 15. The worm 16 can drive the worm gear 14 to rotate. The worm gear 14 drives the connecting shaft to rotate.

[0028] Both sides of the protective cover 5 are provided with through holes, which are adapted to the cylindrical rack 18. The cylindrical rack 18 can pass through the through holes on both sides of the protective cover 5.

[0029] A pair of limiting blocks 19 are fixedly connected to the side of the guide rail 2 away from the substation box 1. The limiting blocks 19 can restrict the movement range of the moving frame 3 on the guide rail 2 and prevent the moving frame 3 from slipping. When the moving frame 3 contacts the limiting block 19 away from the protective cover 5, the ladder 4 on the moving frame 3 can rotate and stand upright on the corresponding position on the side of the protective cover 9, so that the L-shaped fixing block 13 fixes the ladder 4. When the moving frame 3 contacts the limiting block 19 close to the protective cover 5, the ladder 4 on the moving frame 3 is in a suitable position below the box door 8, and the box door 8 is fully opened at the same time.

[0030] A handle 20 is fixedly connected to one side of the ladder 4. The ladder 4 can be rotated on the moving frame 3 by the handle 20. Pushing the handle 20 can move the ladder 4 closer to the protective cover 5.

[0031] The working principle of this utility model is as follows:

[0032] Limiting block 19 can restrict the movement range of moving frame 3 on guide rail 2 to prevent moving frame 3 from slipping. When moving frame 3 contacts limiting block 19 away from protective cover 1 5, ladder 4 on moving frame 3 can rotate and stand upright on the corresponding position on one side of protective cover 2 9. One side of ladder 4 is close to protective cover 2 9. L-shaped fixing block 13 hooks and fixes the two support rods of ladder 4 respectively, so that ladder 4 is stored on one side of substation box 1. The vertically stored ladder 4 is stable and does not shake. During vehicle travel, it will not be damaged by bumps and collisions, ensuring transportation safety. When it is necessary to release ladder 4, servo motor 10 is started. The output end of servo motor 10 drives bidirectional threaded rod 11 to rotate. Bidirectional threaded rod 11 drives a pair of nuts 12 to move closer to each other, so that L-shaped fixing block 13 moves away from the corresponding support rod of ladder 4, so that ladder 4 is released. When arriving at the emergency site, staff can quickly unlock ladder 4, put down ladder 4 to carry out work, greatly shorten the preparation time and improve emergency response efficiency.

[0033] When the ladder 4 is lowered, it causes the moving frame 3 to slide on the guide rail 2 until the moving frame 3 contacts the limiting block 19 near the protective cover 5. At this point, the ladder 4 on the moving frame 3 is in a suitable position below the door 8. Simultaneously, the cylindrical rack 18 moves with the moving frame 3, and the cylindrical rack 18 drives the gear 17 that meshes with it to rotate. The gear 17 drives the worm 16 on the support block 15. The worm 16 can drive the worm wheel 14 that meshes with it to rotate. The worm wheel 14 drives the connecting shaft to rotate. The connecting shaft drives the door 8 to open through the connecting block 7. This allows the door 8 to open just as the worker pushes the ladder 4 into place, eliminating the need to operate the door 8 separately and greatly saving time and effort.

[0034] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
