Description

Technical Field

[0001] This utility model belongs to the field of toolbox technology and relates to a relay protection debugging toolbox. Background Technology

[0002] Relay protection is an important measure to detect faults or abnormalities in power systems, thereby issuing alarm signals or directly isolating or cutting off the faulty part. When operators are debugging relay protection, they need to use various tools. In order to facilitate the overall access of personnel, these tools are usually placed in a toolbox and moved by personnel.

[0003] A Chinese patent for a relay protection debugging toolbox (application number: CN202323413777.4, publication number: CN222038485U, publication date: 2023-12-14) includes a support rod and a toolbox. The toolbox is located on one side of the support rod. An adjustment structure is provided on one side of the support rod, including a connecting rod. One side of the connecting rod is fixedly connected to the support rod, and a winch is fixedly connected to the side of the connecting rod away from the support rod. A pull rope is wound on the drum of the winch, and a fixing block is fixedly connected to the free end of the pull rope. The toolbox is fixedly connected to the fixing block. The winch is used to drive the winding and unwinding of the pull rope, causing the toolbox, fixedly connected to the fixing block, to move up and down along the support rod. However, the above device still has the following problems in its implementation:

[0004] When users inspect faults in power systems, they need to frequently retrieve tools from the toolbox.

[0056] Example 7

[0057] This embodiment provides a relay protection debugging toolbox, such as Figure 1 As shown, the box includes a box body 1 and a box cover 2. The box cover 2 is hinged to one side of the box body 1. The box body 1 is provided with a storage compartment 4. The edge of the storage compartment 4 is attached to the inner wall of the box body 1. A transmission mechanism is provided at the bottom of the box body 1. The transmission mechanism is connected to a stabilizing frame 3 provided on the lower surface of the box body 1. The transmission mechanism is also connected to an adjustment mechanism provided in the box body 1. The adjustment mechanism is connected to the storage compartment 4. The storage compartment 4 moves along the height direction of the box body 1.

[0058] like Figure 2As shown, the adjustment mechanism includes a threaded rod 7 located at the bottom of the housing 1. One end of the threaded rod 7 extends out of the housing 1, and a turning block 24 is fixed to the end of the threaded rod 7 extending out of the housing 1. A bearing seat 23 is provided at the end of the threaded rod 7 inside the housing 1, and a bearing is provided between the bearing seat 23 and the threaded rod 7. Two second transmission blocks 8 are provided on the surface of the portion of the threaded rod 7 inside the housing. The second transmission blocks 8 are provided with threaded holes 10, and the second transmission blocks 8 are threaded onto the threaded rod 7 through the threaded holes 10 and threads. The two threaded holes 10 are threads in opposite directions. A sliding block 21 is fixed to the bottom of the second transmission blocks 8. A sliding groove 22 corresponding to the sliding block 21 is opened on the inner wall of the housing 1. When the threaded rod 7 rotates, the two second transmission blocks 8 move towards or away from each other along the corresponding sliding groove 22. Figure 3 As shown, each of the second transmission blocks 8 has a connecting rod 9 hinged to one end. The two connecting rods 9 are arranged crosswise, and the intersection of the two connecting rods 9 is rotatably connected through the first rotating shaft. The other end of the connecting rod 9 is hinged to the first transmission block 6, as shown. Figure 4 As shown, two first transmission blocks 6 are mounted on slide rail 5. The first transmission blocks 6 move along slide rail 5, and slide rail 5 is fixed to the lower surface of storage compartment 4.

[0059] like Figure 5 As shown, the transmission mechanism includes a first rack 12 fixed on the second transmission block 8, the first rack 12 meshing with a transmission gear 11, the transmission gear 11 being rotatably connected to the housing 1 via a second rotating shaft, the transmission gear 11 also meshing with a second rack 13, the first rack 12 and the second rack 13 being arranged parallel to the threaded rod 7, the second rack 13 being fixedly connected to the stabilizing frame 3 via a connecting block 14, as shown. Figure 4 As shown, the bottom plate of the housing 1 has a connecting groove 15. The connecting block 14 passes through the connecting groove 15 and connects to the stabilizing frame 3. The connecting block 14 can slide in the connecting groove 15. There are two stabilizing frames 3, which are symmetrically arranged on the bottom surface of the housing 1. The stabilizing frames 3 correspond one-to-one with the second rack 13. Two parallel guide rods 19 are arranged between the two stabilizing frames 3. The guide rods 19 are parallel to the threaded rods 7. A positioning block 18 is fixed in the middle of the guide rods 19. The stabilizing frame 3 has a guide hole 20 corresponding to the guide rod 19. 19 extends into the corresponding guide hole 20. By setting the positioning block 18, guide rod 19 and guide hole 20, when the transmission mechanism drives the stabilizer 3, it can restrict the stabilizer 3 to only move along the movement trajectory of guide rod 19 and guide hole 20, and at the same time improve its stability during movement. The bottom surface of the stabilizer 3 is fixed with a rubber anti-slip pad 16. The surface of the rubber anti-slip pad 16 is evenly provided with multiple anti-slip patterns 17. The rubber anti-slip pad 16 can play an anti-slip role, improve the stability of the stabilizer 3 in contact with the ground, and further improve the stability of the toolbox.

[0060] In this embodiment, by setting a transmission mechanism, while the two second transmission blocks 8 move toward each other, the first rack 12 will move. The first rack 12 will drive the transmission gear 11 to rotate around the second rotating shaft. At the same time, the transmission gear 11 will drive the two second racks 13 to move away from each other. The second racks 13 will drive the connecting block 14 and the support frame to move along the trajectory of the guide rod 19 and the guide hole 20. Finally, the two stabilizing frames 3 will unfold to both sides, thereby increasing the contact area with the ground and thus improving the overall stability of the toolbox.

[0061] In this embodiment, considering that users need to frequently retrieve tools from the toolbox when detecting faults in the power system, and that the toolbox is low, requiring users to bend over multiple times to retrieve tools, resulting in high labor intensity, an adjustment mechanism is provided. When the tool retrieval height needs adjustment, rotating the screw block 24 causes the threaded rod 7 to rotate around the bearing. The external thread of the threaded rod 7 presses against the internal thread of the threaded hole 10, causing the two second transmission blocks 8 to move away from each other along the tracks of the sliding block 21 and the sliding groove 22. Simultaneously, the first transmission block 6 moves, pressing the two connecting rods 9 to rotate around the first rotating shaft. The connecting rods 9 also pry the two first transmission blocks 6 to move closer together along the track of the slide rail 5. At the same time, supported by the connecting rods 9 and the first transmission blocks 6, the storage compartment 4 gradually moves upwards. Once it reaches the appropriate position, rotating the screw block 24 stops. At this point, the height of the storage compartment 4 matches the user's height, eliminating the need for the user to bend over to pick up tools and reducing labor intensity.

[0062] This embodiment represents only a preferred implementation of the relay protection debugging toolbox of this utility model. Any toolbox designed with similar technical features to this utility model will fall within the protection scope of the relay protection debugging toolbox of this utility model.

[0063] The working principle of this utility model relay protection debugging toolbox is as follows:

[0064] When the height of the tool needs to be adjusted, the screwing block 24 is rotated. The screwing block 24 will cause the threaded rod 7 to rotate around the bearing. The external thread on the surface of the threaded rod 7 will press against the internal thread of the threaded hole 10, which will drive the two second transmission blocks 8 to move away from each other along the trajectory of the sliding block 21 and the sliding groove 22. At the same time, the first transmission block 6 will press the two connecting rods 9 to rotate around the first rotating shaft. At the same time, the connecting rods 9 will pry the two first transmission blocks 6 to move closer to each other along the trajectory of the slide rail 5. Meanwhile, with the support of the connecting rods 9 and the first transmission blocks 6, the storage compartment 4 will gradually move upward. After reaching the appropriate position, the screwing block 24 can be stopped. At this time, the height of the storage compartment 4 matches the user's height, so the user does not need to bend over to pick up the tool, reducing the user's labor intensity.

[0065] As the two second transmission blocks 8 move toward each other, they drive the first rack 12 to move. The first rack 12 drives the transmission gear 11 to rotate around the second shaft. At the same time, the transmission gear 11 drives the two second racks 13 to move away from each other. The second racks 13 drive the connecting block 14 and the support frame to move along the trajectory of the guide rod 19 and the guide hole 20. Finally, the two stabilizing frames 3 unfold to both sides, thereby increasing the contact area with the ground and thus improving the overall stability of the toolbox.

[0066] The present invention provides a detailed description of a relay protection debugging toolbox. Specific examples have been used to illustrate the implementation of the present invention. The description of the above embodiments is only for the purpose of helping to understand the structure and core idea of ​​the present invention. At the same time, those skilled in the art will recognize that there will be changes in the specific implementation and application scope based on the idea of ​​the present invention. Therefore, the content of this specification should not be construed as a limitation of this application.
