Description

Technical Field

[0001] This invention belongs to the field of power communication technology, and specifically relates to a portable power communication operation and maintenance device. Background Technology

[0002] In the operation and maintenance of power communication networks, portable power communication operation and maintenance devices are widely used in various scenarios such as substations, power plants, and outdoor power communication nodes to enable on-site testing, debugging, fault diagnosis, and signal relay of power communication lines and equipment. Their portability and practicality directly affect the efficiency and quality of operation and maintenance work. These devices typically integrate core components such as communication modules, detection modules, control modules, and power supply modules, all housed in a single enclosure. To facilitate the movement and transportation of the device, most existing portable power communication operation and maintenance devices are equipped with wheels at the bottom of the enclosure. These wheels allow for rapid transfer between different operation and maintenance scenarios, reducing the workload for personnel and aligning with the design intent of portable equipment.

[0003] Currently, in existing technologies, the wheels at the bottom of portable power communication maintenance device enclosures are mostly fixedly installed, meaning they are fixedly connected to the bottom of the enclosure. This only allows for rolling movement and cannot be adjusted for height or storage according to the needs of the usage scenario. In actual power communication maintenance and repair operations, the ground at the maintenance site is often uneven or contains debris. Furthermore, it is crucial to ensure the stable fixation of the device enclosure during maintenance to prevent displacement due to the wheels rolling, which could affect testing accuracy and debugging results. Therefore, workers must use additional support structures such as anchor bolts and support feet to lift the device enclosure off the wheels, thus detaching the wheels from the ground and achieving stable positioning of the enclosure.

[0004] However, with existing equipment, staff need to install and adjust the support structures such as the feet separately each time maintenance is performed. After the maintenance is completed, the support structures also need to be disassembled, which adds extra steps, consumes a lot of manpower and time, and seriously reduces the overall efficiency of maintenance. On the other hand, the adjustment process of the foot support structure is cumbersome and requires repeated adjustments to make the enclosure reach a horizontal and stable state. Especially in complex outdoor maintenance scenarios, the ground is not flat and the adjustment is more difficult. This not only increases the workload of the staff, but may also cause the enclosure to tilt due to improper adjustment, affecting the accuracy of maintenance, testing and debugging. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention aims to provide a portable power communication operation and maintenance device. This device can perform efficient operation and maintenance testing of power communication facilities, effectively meeting the practical needs of efficient, convenient, and flexible power communication operation and maintenance work. It effectively solves the technical problems of inconvenient installation and debugging, low operation and maintenance efficiency, heavy operational burden, and impact on the portability of the device in existing technologies.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A portable power communication operation and maintenance device includes a housing and an operation and maintenance testing component. The housing has a window on its front side, a side panel installed at the window, and a window opener connected to the side panel. The side panel is fixed to the housing by a latch. The bottom surface of the housing has an upward-facing groove, within which two L-shaped flip frames are symmetrically installed. A wheel is installed at one right-angled end of each flip frame, and a support leg is installed at the other right-angled end. A synchronous flip drive component connected to the two flip frames is located within the groove, driving the two flip frames to flip synchronously and switching the support of the wheel and support leg on the ground. The operation and maintenance testing component is installed inside the housing. A telescopic rod is installed on the side of the housing.

[0007] Preferably, the synchronous flipping drive assembly includes a lateral drive, a connecting rod, and two moving blocks, the moving blocks being slidably mounted left and right within the groove; the right-angle end of the flipping frame is rotatably connected to the lower part of the corresponding moving block; one end of the connecting rod is rotatably mounted on the inner side of the groove away from the moving block, and the other end of the connecting rod is rotatably connected to the middle of the right-angle side of the flipping frame; the actuating part of the lateral drive is connected to the two moving blocks, and is used to drive the two moving blocks to move away from or closer to each other.

[0008] Preferably, the connecting rods are symmetrically arranged on the front and rear sides of the flipping frame.

[0009] Preferably, a sliding rod is horizontally installed in the groove in the left-right direction, and the moving block is slidably sleeved on the sliding rod.

[0010] Preferably, the transverse drive includes a screw and a crank handle. The screw is horizontally arranged in the left-right direction and rotatably installed in the groove. One end of the screw extends through the groove and out of the housing body and is concentrically fixed to the crank handle. Two moving blocks are respectively threaded onto the positive and negative threads on both sides of the screw.

[0011] Preferably, the window opener includes a hinge block, a first flip rod, a second flip rod, and a tension spring. The side plate is movably disposed at the window, and the hinge block is rotatably mounted on the upper edge of the window opening. A vertical groove is provided on the inner sidewall of the side plate, and the hinge block is slidably engaged in the groove. One end of the first flip rod and the second flip rod are vertically fixedly connected, and the vertical connection point of the two flip rods is rotatably connected to the inner sidewall of the window. The other end of the first flip rod is rotatably connected to the lower inner side of the side plate, and the other end of the second flip rod is rotatably connected to one end of the tension spring. The other end of the tension spring is horizontally rotatably connected to the inner sidewall of the box.

[0012] Preferably, the hinge block has a T-shaped bayonet through it, and the slide groove includes two symmetrically opened L-shaped through slots, and the T-shaped bayonet is slidably engaged in the two L-shaped through slots of the slide groove.

[0013] Preferably, the latch is installed on the lower edge of the side plate; a handle is provided on the outer side of the side plate.

[0014] Preferably, a first magnetic block is installed on the upper edge of the side plate, and a second magnetic block that cooperates with the first magnetic block is fixed on the side of the top window of the box.

[0015] Preferably, the operation and maintenance detection component includes a core control module, a power supply module, a communication detection module, a fault location module, a data storage module, and a human-machine interaction module; The core control module is used to coordinate the work of all functional modules, receive detection data and instruction signals from each module, perform simple data processing and logical judgment, and control the issuance of instructions. The power module is used to provide a stable operating voltage for all modules of the device and has overcharge, over-discharge and short circuit protection functions. The communication detection module is used to quickly detect the connectivity status, signal strength, and transmission rate of the communication link, and to identify abnormal signals in the link. The fault location module is used to quickly locate the fault location; The data storage module is used to record detection data and fault information, and the data can be exported through the interface; The human-computer interaction module includes a touch screen for controlling and displaying various parameters of power communication.

[0016] The beneficial effects of this invention are as follows: 1. This invention coordinates the overall operation through a core control module, provides stable power supply through a power module, efficiently completes link detection and anomaly location through a communication detection and fault location module, retains data through a data storage module, and simplifies the operation process through a human-machine interaction module. Ultimately, it achieves device integration and portability, enabling rapid commencement of power communication operation and maintenance work without complex assembly. This significantly reduces the workload of maintenance personnel, shortens fault diagnosis time, and improves on-site operation and maintenance efficiency. At the same time, it ensures stable operation of the device in complex outdoor environments, extends its service life, and adapts to various power communication on-site operation and maintenance scenarios.

[0017] 2. This application utilizes a handle to push the side panel upwards. With the rotational cooperation of the first and second flipping rods, the tension spring is stretched, the hinge block rotates upwards, and the side panel flips and slides on the hinge block, ultimately allowing the side panel to be flipped and supported on the top of the housing. This achieves the flipping and opening of the side panel without affecting the operator's access to the maintenance and testing components through the window. When the side panel is closed, pulling it downwards with the handle, under the spring force, and through the cooperation of the flipping plate, hinge block, and other structures, makes the flipping and closing of the side panel easier and more convenient.

[0018] 3. When the screw is rotated by the crank, the movable blocks fitted on the positive and negative threads of the screw will move away from or towards each other under the sliding limit of the slide rod. When the movable blocks move away from each other, the connecting rod rotates upward and under its hinge limit, the tilting frame will rotate around the hinge point of the movable blocks, causing the right-angle side of the tilting frame mounting feet to flip to a horizontal state and the right-angle side of the mounting wheels to flip to a vertical downward state, thus supporting the four wheels on the ground and enabling the device to move. When the movable blocks move towards each other, the connecting rod rotates downward, causing the right-angle side of the tilting frame mounting wheels to rotate to a horizontal state and the right-angle side of the mounting feet to be in a vertical state, thus the feet stably support the device and effectively prevent the box from moving backward during operation and maintenance, which would affect the testing.

Detailed Implementation

[0020] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are for illustrative purposes only and are not intended to limit the scope of the invention.

[0021] like Figure 1-3As shown, this invention proposes a portable power communication operation and maintenance device, including a housing 1 and an operation and maintenance detection component, which is installed in the housing 1. A telescopic pull rod 12 is installed on the side of the housing 1 to facilitate the movement and pushing / pulling of the device. The operation and maintenance detection component includes a core control module, a power supply module, a communication detection module, a fault location module, a data storage module, and a human-machine interaction module.

[0022] The core control module, serving as the "central control hub" of the device, employs a low-power embedded chip. It coordinates the operation of all functional modules, receives detection data and instruction signals from each module, performs simple data processing and logical judgments, and issues control instructions (such as controlling the start of the detection module, data storage / transmission, etc.). This ensures the coordinated and stable operation of all modules and is the core support for the normal operation of the device.

[0023] The power module is designed for portable applications and uses a rechargeable lithium battery (supporting fast charging and long battery life). It also integrates a power management unit to provide a stable operating voltage for all modules in the device (adapting to the voltage requirements of different modules). It features overcharge, over-discharge, and short-circuit protection and allows manual switching between power supply modes (battery power / external power supply) to meet the needs of outdoor maintenance scenarios without external power sources.

[0024] The communication detection module is a core operation and maintenance function module. It is compatible with common power communication links (such as fiber optic, Ethernet, RS485 bus, etc.) and can quickly detect the on / off status, signal strength, and transmission rate of the communication link. It can also identify abnormal signals in the link (such as interference and attenuation). It can complete basic communication testing directly on-site without the need for complex external equipment, providing a preliminary basis for troubleshooting.

[0025] The fault location module, an auxiliary operation and maintenance module, works in conjunction with the communication detection module. When an abnormality in the communication link is detected, it can quickly locate the approximate location of the fault (such as fiber optic break or poor bus contact). It provides simple signal feedback (such as indicator lights or simple numerical values) to prompt operation and maintenance personnel, reducing the time cost of fault diagnosis and meeting the needs of rapid on-site operation and maintenance.

[0026] The data storage module includes a small storage unit and a simple display screen: the storage unit can record test data and fault information (supports short-term storage for easy review later), and the data can be exported through an interface.

[0027] The human-computer interaction module includes a touch screen installed at window 15 and a simple operation module with a few operation buttons (such as power on, detection start, mode switching, and data export). The button layout is simple and suitable for outdoor operation while wearing gloves. It can realize manual control of the start / stop of each module and adjustment of detection parameters (simple parameters) to meet the basic operation and maintenance needs in different scenarios.

[0028] This invention achieves overall coordination through a core control module, stable power supply through a power module, efficient link detection and fault location through a communication detection and fault location module, data storage through a data retention module, and simplified operation through a human-machine interaction module. Ultimately, it realizes device integration and portability, enabling rapid commencement of power communication operation and maintenance work without complex assembly. This significantly reduces the workload of maintenance personnel, shortens fault diagnosis time, and improves on-site operation and maintenance efficiency. At the same time, it ensures stable operation of the device in complex outdoor environments, extends its service life, and adapts to various power communication on-site operation and maintenance scenarios.

[0029] A window 15 is provided on the front side of the housing 1, and a side plate 2 is installed at the window 15. A window opener connected to the side plate 2 is installed at the window 15; the side plate 2 is fixedly connected to the housing 1 by a latch. Specifically, the window opener includes a hinge block 16, a first flip rod 61, a second flip rod 62, and a tension spring 63. The side plate 2 is movably disposed at the window 15, and the hinge block 16 is rotatably mounted on the upper edge of the opening of the window 15. A vertical sliding groove 21 is provided on the inner wall of the side plate 2, and the hinge block 16 is slidably engaged in the sliding groove 21. The hinge block 16 has a through-hole T-shaped latch, and the sliding groove 21 includes two symmetrically arranged L-shaped through slots. The T-shaped latch is slidably engaged in the two L-shaped through slots of the sliding groove 21. Through the sliding engagement of the T-shaped latch and the L-shaped through slots on the sliding groove 21, the hinge block 16 can slide smoothly along the sliding groove 21. One end of the first flip rod 61 and the second flip rod 62 are vertically fixed together, and the vertical connection point of the two flip rods is rotatably connected to the inner wall of the window 15. The other end of the first flip rod 61 is rotatably connected to the lower inner side of the side plate 2, and the other end of the second flip rod 62 is rotatably connected to one end of the tension spring 63. The other end of the tension spring 63 is horizontally rotatably connected to the inner wall of the box 1. The latch is installed on the lower edge of the side plate 2; a handle 21 is provided on the outer side of the side plate 2.

[0030] This application pushes the side plate 2 upwards using the handle 21. With the rotational cooperation of the first flipping rod 61 and the second flipping rod 62, the tension spring 63 is stretched, the hinge block 16 rotates upwards, and the side plate 2 flips and slides on the hinge block 16, ultimately allowing the side plate 2 to be flipped and supported on the top of the housing 1. This allows the side plate 2 to be flipped open without affecting the operator's operation and maintenance testing of the maintenance and testing components through the window 15. When the side plate 2 is closed, the handle 21 is pulled downwards. Under the action of the spring force, the flipping plate, the hinge block 16, and other structures make the flipping and closing of the side plate 2 easier and more convenient.

[0031] A first magnetic block is installed on the upper edge of the side panel 2, and a second magnetic block 11 that cooperates with the first magnetic block is fixed on the side of the principle window 15 on the top of the box 1.

[0032] When the side panel 2 of the present invention is flipped to the top of the box 1, the side panel 2 can be fixed by the attraction of the first magnetic block and the second magnetic block 11, which effectively prevents the side panel 2 from slipping off during testing.

[0033] The bottom surface of the housing 1 has a groove 14 facing upwards. Two L-shaped tilting frames 33 are symmetrically installed in the groove 14. A walking wheel 51 is installed at one right-angle end of the tilting frame 33, and a support foot 52 is installed at the other right-angle end. A synchronous tilting drive assembly connected to the two tilting frames 33 is provided in the groove 14. The synchronous tilting drive assembly is used to drive the two tilting frames 33 to tilt synchronously and switch the support of the walking wheel 51 and the support foot 52 on the ground. The synchronous tilting drive assembly includes a lateral drive, a connecting rod 44 and two moving blocks 43. The moving blocks 43 are slidably installed in the groove 14. In this embodiment, a sliding rod 41 is horizontally installed in the groove 14 in the left and right direction, and the moving blocks 43 are slidably sleeved on the sliding rod 41. The right-angle end of the tilting frame 33 is rotatably connected to the lower part of the corresponding moving block 43; connecting rods 44 are symmetrically arranged on the front and rear sides of the tilting frame 33, one end of the connecting rod 44 is rotatably installed on the inner side of the groove 14 away from the moving block 43, and the other end of the connecting rod 44 is rotatably connected to the middle of the right-angle side of the tilting frame 33; the actuating part of the transverse drive is connected to the two moving blocks 43 and is used to drive the two moving blocks 43 to move away from or closer to each other. The transverse drive includes a screw 42 and a crank 13. The screw 42 is horizontally arranged in the left-right direction and rotatably installed in the groove 14. One end of the screw 42 passes through the groove 14, extends out of the housing 1, and is concentrically fixed to the crank 13; the two moving blocks 43 are respectively threaded onto the positive and negative threads on both sides of the screw 42.

[0034] When the screw 42 is rotated by the crank 13, the movable blocks 43 fitted on the positive and negative threads of the screw 42 will move away from or towards each other under the sliding limit of the slide rod 41. When the movable blocks 43 move away from each other, the connecting rod 44 rotates upward and under its hinge limit, the flipping frame 33 will rotate around the hinge point of the movable blocks 43, so that the right-angle side of the mounting leg 52 of the flipping frame 33 flips to the horizontal state and the right-angle side of the mounting wheel 51 flips to the vertical downward state, so that the four wheels 51 are supported on the ground, thus realizing the movement of the device. When the movable blocks 43 move towards each other, the connecting rod 44 will rotate downward, so that the right-angle side of the mounting wheel 51 of the flipping frame 33 rotates to the horizontal state and the right-angle side of the mounting leg 52 is in the vertical state, so that the mounting leg 52 stably supports the device, effectively preventing the box 1 from moving backward during operation and maintenance and testing, thus affecting the testing and use.

[0035] When using this invention, after moving the device to the testing area, rotate the crank handle 13. Through the cooperation of the screw 42, moving block 43, connecting rod 44, flipping frame 33 and other structures, the bottom walking wheels 51 of the box 1 are folded up, and the box 1 is stably supported by the support feet 52. Then push the side plate 2 up to the top of the box 1, and the power communication operation and maintenance testing work can be carried out through the operation and maintenance testing components in the window 15.
