Description

Technical Field

[0001] This utility model relates to the field of power system construction and operation and maintenance technology, specifically to a signal transfer device for the migration of the main distribution network system. Background Technology

[0002] The migration of the main and distribution network systems is a routine operation carried out by the power industry to improve the reliability, capacity expansion, or intelligent upgrade of the power grid. Its core is to safely and seamlessly switch the load from the old substation, switchgear, or line to the new system without affecting the power supply to users or minimizing the power outage time. Among them, the signal transfer device is a key auxiliary equipment for the migration of the main and distribution network systems. It is essentially a temporary "bridge" installed between the old and new systems. Through its internal terminal blocks, transformers, and other components, the old secondary cables are connected, and after necessary isolation and conversion, they are output to the new protection and control devices, thereby achieving a seamless switch of signal paths in physical terms.

[0003] Existing signal transfer devices lack auxiliary facilities for on-site technicians, forcing operators to carry their own tool bags or find temporary platforms to place instruments and tools. This not only significantly reduces work efficiency but also increases the risk of tools slipping, being lost, or even falling into operating equipment. Secondly, the enclosures of existing signal transfer devices have cable entry points for temporary cables, which are easily left open due to human negligence after work, exposing the delicate electrical components inside to dust and moisture for extended periods, seriously threatening the insulation performance and long-term operational reliability of the equipment. Therefore, those skilled in the art provide a signal transfer device for migrating main and distribution network systems to solve the problems mentioned in the background. Utility Model Content

[0004] The purpose of this utility model is to provide a signal transfer device for the migration of the main distribution network system, and to solve the problems mentioned in the background art above.

[0005] This utility model provides the following technical solution: a signal transfer transition device for main distribution network system migration, including a protective enclosure and a transition component body for signal transfer. The transition component body is installed inside the enclosure. A storage groove is provided on one side of the outer wall of the enclosure. A placement component for carrying objects is installed in the storage groove. A wire-passing port is provided on both the inner wall of the storage groove and the inner wall of one side of the enclosure. A protective component for blocking one of the wire-passing ports is installed inside the enclosure.

[0006] As a preferred embodiment of the above technical solution, the placement component includes a carrying plate, which is rotatably connected to the lower part of the inner wall of the storage slot. The box body has a working cavity, and a worm gear is rotatably connected to one side of the inner wall of the working cavity.

[0007] As a preferred embodiment of the above technical solution, a worm gear is rotatably connected to one side of the inner wall of the working chamber, the worm gear and the worm wheel mesh with each other, the output end of the worm wheel penetrates the inner wall of the working chamber, and the output end of the worm wheel is fixedly connected to one side of the carrying plate, and a knob is rotatably connected to one side of the box body, the output end of the knob penetrates the box body, and the output end of the knob is fixedly connected to one end of the worm gear.

[0008] As a preferred embodiment of the above technical solution, the protective component includes guide rails, and two guide rails are provided. Both guide rails are fixedly connected to the inner wall of the box, and a baffle is slidably connected to the outside of the two guide rails. The baffle matches one of the wire passages.

[0009] As a preferred embodiment of the above technical solution, a rotating rod is fixedly connected to the end of the worm gear away from the knob, one end of the rotating rod is rotatably connected to the inner wall of the working cavity, a first bevel gear is fixedly sleeved on the outside of the rotating rod, and a second bevel gear is rotatably connected to the inner wall of the working cavity near the transition component body, and the first bevel gear and the second bevel gear mesh with each other.

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0015] Please see Figures 1-6 As shown, this utility model provides a technical solution: a signal transfer transition device for main distribution network system migration, including a protective enclosure 1 and a transition component body 2 for signal transfer. The transition component body 2 is installed inside the enclosure 1. A storage groove 3 is provided on one side of the outer wall of the enclosure 1. A placement component 4 for carrying objects is installed in the storage groove 3. A wire threading port 5 is provided on both the inner wall of the storage groove 3 and the inner wall of one side of the enclosure 1. A protective component 6 for blocking one of the wire threading ports 5 is installed inside the enclosure 1.

[0016] Furthermore, the placement component 4 in this device provides a safe and convenient temporary operating platform for on-site technicians. The self-locking feature of the placement component 4 ensures that the unfolded placement component 4 can stably and reliably support tools, instruments and other items without accidentally tipping over, greatly improving operating efficiency and solving the pain point of tools having nowhere to be placed and being easily scattered and lost during on-site operations. This effectively improves work efficiency. The protective component 6, through linkage with the placement component 4, realizes the safe action of automatically closing the wire threading port 5 when the placement component 4 is retracted, eliminating the risk of forgetting to close the wire threading port 5 due to human negligence. This effectively prevents dust, moisture or foreign objects from entering the interior of the housing 1 through the wire threading port 5, always maintaining the complete protection level of the housing 1, ensuring the long-term safety and reliability of the internal transition component body 2, and a protective door is hinged on one side of the housing 1.

[0017] It is worth noting that the transition component body 2 is based on existing technology and includes multiple sets of passive contact conversion modules, high-precision signal isolation circuits, terminal blocks with visual indicator lights, and standardized interface modules that support hot-swapping. Its working principle is to achieve adaptive conversion of signal formats through passive contact modules, and distribute them to the output end after purification by the isolation circuit. At the same time, relying on the hot-swappable design and status indication function, it can safely and transparently complete the seamless switching of the secondary circuit of the main distribution network system while ensuring the continuity of signal migration throughout the process. This will not be elaborated further here.

[0018] As one implementation method in this embodiment, please refer to Figures 4-5 As shown, the placement component 4 includes a carrying plate 401, which is rotatably connected to the lower part of the inner wall of the storage slot 3. A working cavity 402 is opened inside the box body 1. A worm gear 403 is rotatably connected to one side of the inner wall of the working cavity 402. A worm 404 is rotatably connected to one side of the inner wall of the working cavity 402. The worm 404 and the worm gear 403 mesh with each other. The output end of the worm gear 403 passes through the inner wall of the working cavity 402 and is fixedly connected to one side of the carrying plate 401. A knob 405 is rotatably connected to one side of the box body 1. The output end of the knob 405 passes through the box body 1 and is fixedly connected to one end of the worm 404.

[0019] Furthermore, when using the device, rotating the knob 405 directly drives the worm gear 404 to rotate, which in turn drives the meshing worm wheel 403 to rotate. The output end of the worm wheel 403 is converted into the outward and downward rotational motion of the carrying plate 401, allowing it to unfold smoothly from the storage slot 3 until the carrying plate 401 rotates to a horizontal position or the required angle. Through the mechanical self-locking characteristics of the worm wheel 403 and the worm gear 404, it automatically locks itself. At this point, the carrying plate 401 can stably and reliably support tools, instruments, and other items without accidentally tipping over, greatly improving operational efficiency and solving the pain point of tools having nowhere to be placed and being easily scattered and lost during on-site operations. This effectively improves work efficiency. In addition, a support frame is fixedly connected to the middle of the lower end of the carrying plate 401. When the carrying plate 401 is unfolded to a horizontal position, the support frame can be attached to and supported on the side wall of the housing 1, thereby reducing the load on the worm wheel 403 and the worm gear 404 and improving the stability of the carrying plate 401.

[0020] As one implementation method in this embodiment, please refer to Figures 5-6As shown, the protective component 6 includes two guide rails 601, both of which are fixedly connected to the inner wall of the housing 1. A baffle plate 602 is slidably connected to the outside of both guide rails 601. The baffle plate 602 matches one of the wire-passing ports 5. A rotating rod 603 is fixedly connected to the end of the worm gear 404 away from the knob 405. One end of the rotating rod 603 is rotatably connected to the inner wall of the working chamber 402. A first bevel gear 604 is fixedly sleeved on the outside of the rotating rod 603. The working chamber 402 is located near... A second bevel gear 605 is rotatably connected to one side of the inner wall of the near-transition component body 2. The first bevel gear 604 and the second bevel gear 605 mesh with each other. A spur gear 606 is rotatably connected to the inner wall of the housing 1. The output end of the second bevel gear 605 passes through one side of the inner wall of the working cavity 402, and the output end of the second bevel gear 605 is fixedly connected to one end of the spur gear 606. A rack 607 is fixedly connected to the lower part of the side of the baffle plate 602 near the loading plate 401. The rack 607 and the spur gear 606 mesh with each other.

[0021] Furthermore, when the carrier plate 401 unfolds, one end of the worm gear 404 drives the rotating rod 603 to rotate together. The first bevel gear 604, fixed to the outside of the rotating rod 603, rotates accordingly. The first bevel gear 604 drives the second bevel gear 605 to rotate. The output end of the second bevel gear 605 drives the spur gear 606 to rotate. The rotating spur gear 606 meshes with the rack 607. Since the rack 607 is fixedly mounted on the baffle plate 602, and the baffle plate 602 is confined in the guide rail 601, the rotation of the spur gear 606 drives the rack 607 and the baffle plate 602 to move upward in a straight line. The wire pass-through port 5, which was originally blocked, is exposed, allowing the cable to pass through. After the device is used, the reverse knob 405 is turned off. The carrying plate 401 is reversed and stored in the storage slot 3 for easy movement and storage without taking up extra space. Similarly, the spur gear 606 rotates in the opposite direction to drive the rack 607 and the baffle plate 602 to move downward in a straight line. The baffle plate 602 descends to cover the wire threading port 5, while the other wire threading port 5 is covered by the carrying plate 401. Through the linkage between the baffle plate 602 and the placement component 4, the safe action of automatically closing the wire threading port 5 when the placement component 4 is retracted is realized. This eliminates the risk of forgetting to close the wire threading port 5 due to human negligence, thereby effectively preventing dust, moisture or foreign objects from entering the interior of the housing 1 through the wire threading port 5, always maintaining the complete protection level of the housing 1, and ensuring the safety and reliability of the internal transition component body 2 in long-term operation.

[0022] Working principle: When using the device, rotating the knob 405 directly drives the worm gear 404 to rotate, which in turn drives the meshing worm wheel 403 to rotate. The output end of the worm wheel 403 is converted into the outward and downward rotational motion of the carrying plate 401, which smoothly unfolds from the storage slot 3 until the carrying plate 401 rotates to the horizontal or the required angle and automatically locks. At this time, the carrying plate 401 can stably and reliably support tools, instruments and other items without accidentally tipping over, which greatly improves the operating efficiency and solves the pain point of tools having nowhere to be placed and being easily scattered and lost in on-site operations, effectively improving work efficiency. When the carrier plate 401 unfolds, one end of the worm gear 404 drives the rotating rod 603 to rotate together. The first bevel gear 604, fixed to the outside of the rotating rod 603, rotates accordingly. The first bevel gear 604 drives the second bevel gear 605 to rotate. The output end of the second bevel gear 605 drives the spur gear 606 to rotate. The rotating spur gear 606 meshes with the rack 607. Since the rack 607 is fixedly mounted on the baffle plate 602, and the baffle plate 602 is confined in the guide rail 601, the rotation of the spur gear 606 drives the rack 607 and the baffle plate 602 to move upward in a straight line. The wire pass-through port 5, which was originally blocked, is exposed, allowing the cable to pass through. After the device is used, the reverse... Turning knob 405 reverses the loading plate 401 and retracts it into storage slot 3, making it easy to move and store without taking up extra space. Similarly, the spur gear 606 rotates in the opposite direction, driving rack 607 and baffle 602 to move downwards in a straight line. The baffle 602 descends to cover the wire hole 5. Through the linkage between the baffle 602 and the placement component 4, the safe action of automatically closing the wire hole 5 when the placement component 4 is retracted is realized. This eliminates the risk of forgetting to close the wire hole 5 due to human negligence, thereby effectively preventing dust, moisture or foreign objects from entering the interior of the housing 1 through the wire hole 5, always maintaining the complete protection level of the housing 1, and ensuring the safety and reliability of the internal transition component body 2 in long-term operation.

[0023] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
