Description

Technical Field

[0001] This invention relates to the field of power maintenance technology, and in particular to an insulation isolation device for a low-voltage live-line working branch box. Background Technology

[0002] Power maintenance refers to the regular or irregular inspection, upkeep, modification, and upgrading of equipment and facilities in a power system to ensure its normal operation. It covers all aspects of power generation, transmission, distribution, and consumption, including equipment maintenance and repair, transmission line inspection and repair, fault diagnosis and upgrading of distribution systems, and maintenance of user-side equipment. These are all indispensable parts of the power system and are of great significance for ensuring the stability and security of power supply.

[0003] In the prior art, the patent publication number CN109301739A discloses an insulation isolation device for replacing circuit breakers in a low-voltage cable branch box under live conditions. The low-voltage cable branch box is equipped with a main copper busbar and circuit breakers. The main copper busbar is horizontally arranged, and several circuit breakers are arranged side by side below the main copper busbar. Three connecting copper busbars are arranged side by side between the circuit breakers and the main copper busbar. The insulation isolation device includes an insulation isolation cover, which includes a horizontal support plate, a partition plate connected side by side to the rear side of the horizontal support plate, and a main copper busbar isolation plate vertically connected to the top of the horizontal support plate. The main copper busbar isolation plate covers the front of the main copper busbar, and the partition plate is inserted between two adjacent connecting copper busbars. However, this comparative technology has very few application scenarios and is a fixed structure. Especially in the field, the insulation isolation of low-voltage branch boxes requires a movable insulation isolation device. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that the existing low-voltage branch box is too close to the adjacent lines inside the cabinet, and there is no isolation measure between the fuse holders, which does not meet the safe operating distance. This invention is equipped with a photoelectric sensor, and the wedge block can drive the electromagnet to adjust its position according to the length of the fuse holder. The electromagnet magnetically attracts the frame, thereby further limiting the position and preventing the device from shifting during maintenance, which would affect the maintenance efficiency. This invention provides a convenient low-voltage live-line working branch box insulation isolation device.

[0005] Another objective of this invention is to address the problem that existing low-voltage branch boxes are large in size and pose a risk of electric shock to people and animals when located outdoors. This invention features a downward-folding hinge to insulate the bottom of the branch box as well. Furthermore, this movable structure has a wide range of applications. Existing insulation devices are fixed and cannot be moved, making them very convenient for personnel to carry when going out. This invention provides a widely applicable insulation device for low-voltage live-line working branch boxes.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an insulation isolation device for a low-voltage live-line working branch box, comprising a mounting plate, an adjustment structure two being provided on one side of the mounting plate, a first hinge being symmetrically provided on one side of the adjustment structure two, a side plate being provided on one side of the first hinge, an adjustment structure one being provided on one side of the side plate, a wedge block being fixedly connected to one side of the adjustment structure one, a second hinge being provided on the side of the side plate away from the wedge block, an isolation plate being provided on one side of the second hinge, and a downward folding hinge being provided at the bottom of both the isolation plate and the side plate.

[0007] Preferably, an electromagnet is provided on one side of the wedge block, and a photoelectric sensor is provided on the other side of the wedge block. The adjustment structure includes a first slider, a first rack is fixedly connected to the bottom of the first slider, and a first gear is meshed with the outer wall of the first rack.

[0008] Preferably, a first connecting shaft is fixedly connected to the middle of the first gear, one end of the first connecting shaft passes through one side of the side plate and is fixedly connected to a second driving member, and the other end of the first connecting shaft passes through the middle of the first gear and is rotatably connected to the inside of the side plate.

[0009] Preferably, a first groove is provided on one side of the side plate, and the first slider is slidably connected in the first groove of the side plate. The second driving component includes a motor and a knob, and one side of the second driving component is disposed on the side of the side plate close to each other.

[0010] Preferably, the second adjustment structure includes a first driving member, a second connecting shaft is fixedly connected to one side of the first driving member, a second bevel gear is fixedly connected to one end of the second connecting shaft, and the tooth end of the second bevel gear is meshed with the first bevel gear.

[0011] Preferably, the bottom of the first bevel gear is fixedly connected to a third connecting shaft, the bottom end of the third connecting shaft is rotatably connected to the inside of the mounting plate, the middle of the mounting plate is symmetrically provided with a second sliding groove, and the top of the mounting plate is symmetrically provided with a T-shaped sliding groove.

[0012] Preferably, a second gear is fixedly connected to the middle of the third connecting shaft, the teeth of the second gear are symmetrically meshed with a second rack, and a connecting column is fixedly connected to the side of the second rack that is far away from it.

[0013] Preferably, a second slider is fixedly connected to the top of the connecting column, a movable plate is fixedly connected to the top of the second slider, and T-shaped sliders are symmetrically fixedly connected to the bottom of the movable plate. The side of the movable plate that is furthest away from the first hinge is located on one side.

[0014] Preferably, a photoelectric sensor 2 is provided on one side of the movable plate, the outer wall of the second slider is slidably connected to the second groove of the mounting plate, and the outer wall of the T-shaped slider is slidably connected to the T-shaped groove of the mounting plate.

[0015] Preferably, the outer wall of the second connecting shaft is rotatably connected to one side of the mounting plate, and the first driving component includes a motor and a knob, with one side of the first driving component disposed on one side of the mounting plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention uses a wedge-shaped block to hang the device on the copper plate at the rear end of the fuse holder in the low-voltage branch box, thereby reinforcing the device. The side plate isolates the fuse holder that needs maintenance from the other fuse holders. Then, by rotating the isolation plate, the fuse holder that needs maintenance is exposed for maintenance. The first and second hinges allow the device to be folded when not in use. The overall structure of the device is small, making it easy to carry. This solves the problem that frequent power outages during low-voltage branch box maintenance require the shutdown of nearby lines, which significantly impacts the reliable power supply for residential users.

[0017] This invention uses a second driving component to rotate a first connecting shaft, causing a first gear to rotate, which in turn moves a first rack, thereby moving a first slider through a first sliding groove. This causes a wedge-shaped block to move, which in turn moves a photoelectric sensor and an electromagnet. The photoelectric sensor detects the width of the weld bead, and the electromagnet attracts the wedge-shaped block to the frame behind the weld bead, further limiting the device's position. This allows the device to be adjusted according to the width of the weld bead in different low-voltage branch boxes, making it suitable for weld beads of different widths and thus enhancing its practicality.

[0018] This invention uses a first driving component to drive a second connecting shaft to rotate, thereby causing two second racks to move horizontally left and right, which in turn drives the connecting column to move horizontally left and right. This allows the two moving plates to move away from or towards each other. A T-shaped slider makes the movement of the moving plates more stable. The movement of the moving plates causes the side plates to move horizontally left and right on the mounting plate. This allows the position of the side plates to be adjusted according to the length of the weld base to be maintained, making it suitable for weld bases of different lengths and further enhancing the practicality of the device.

[0028] The technical solution of the present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. The described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] Example 1: Refer to Figures 1 to 8 This paper presents an insulation isolation device for low-voltage live-line working branch boxes. Low-voltage branch boxes have complex internal structures, especially with the parallel installation of multiple switches, resulting in limited spacing between fuse holders. This can easily lead to safety hazards during operation due to proximity to nearby lines. To address this issue, this paper designs an insulation isolation device for low-voltage live-line working branch boxes. Through a rational mechanical structure design and intelligent adjustment functions, this device effectively isolates the fuse holder requiring maintenance from other fuse holders, preventing misoperation. It also meets the compatibility requirements of fuse holders of different sizes, improving operational efficiency and safety.

[0030] The device consists of a mounting plate 1 and a side plate 2, which are connected by a first hinge 3 and a second hinge 4. The mounting plate 1 serves as the base of the device and is fixed to the frame of the branch box, while the side plate 2 can rotate up and down via hinges, facilitating the folding and unfolding of the device. One side of the side plate 2 is connected to an isolation plate 6 via the second hinge 4. The isolation plate 6 can rotate left and right to cover or expose the fusion seat.

[0031] Both the partition plate 6 and the side plate 2 are provided with a bottom hinge 29. When the device is retracted, the bottom hinge 29 can also be folded up to protect the bottom of the branch box.

[0032] The device is equipped with two adjustment mechanisms: Adjustment Mechanism One and Adjustment Mechanism Two. Adjustment Mechanism Two is responsible for moving the side plate 2 horizontally left and right on the mounting plate 1 to accommodate welding bases of different lengths; Adjustment Mechanism One, on the other hand, adapts to welding bases of different widths by moving the wedge block 5 back and forth. The design of the wedge block 5 allows it to be securely hung on the rear connection plate of the branch box welding base, ensuring the stability of the device.

[0033] An electromagnet 26 is installed on one side of the wedge-shaped block 5 to attract it behind the fusion seat, further enhancing the limiting effect of the device. A photoelectric sensor 27 is installed on the other side to detect the width of the fusion seat, providing data support for the adjustment structure and ensuring precise positioning of the wedge-shaped block 5. All components of the device are made of acrylic glass. Acrylic glass is lightweight, has high mechanical strength, is easy to process, has strong impact resistance, good weather resistance, and strong flame retardancy. It is also self-extinguishing. These characteristics make the device safe, portable, and easy to install, making it particularly suitable for the complex environment of low-pressure branch boxes.

[0034] The main function of the second adjustment structure is to adjust the position of the side plate 2 to accommodate welding seats of different lengths. A drive device (such as a motor or manual knob) moves the first hinge 3 and the side plate 2 horizontally left and right on the mounting plate 1. This design allows the device to flexibly adapt to branch boxes of different sizes, avoiding installation difficulties caused by size mismatches.

[0035] The adjustment structure 1 achieves the forward and backward movement of the wedge block 5 through the cooperation of the first slider 13, the first rack 12, and the first gear 11. Specifically, the second driving component 9 (motor or knob) drives the first connecting shaft 10 to rotate, which in turn drives the first gear 11 to rotate. Since the first rack 12 meshes with the first gear 11, the rack will move horizontally back and forth inside the side plate 2, causing the slider 13 to slide along the slide groove 14, ultimately achieving the position adjustment of the wedge block 5.

[0036] The photoelectric sensor 27 detects the width of the weld bead in real time and feeds the data back to the adjustment mechanism. When the second drive component 9 is a motor, the motor automatically adjusts the position of the wedge block 5 according to the sensor signal; when the drive component is a knob, the operator can manually adjust the position of the wedge block 5 according to the sensor reading. This design satisfies the requirements of automation while retaining the flexibility of manual adjustment.

[0037] The design of side plate 2 and isolation plate 6 effectively isolates the weld bead requiring maintenance from other weld beads. By rotating isolation plate 6, the target weld bead can be exposed while other weld beads are blocked, preventing accidental operation. This isolation measure significantly improves operational safety. The device has a compact overall structure, is lightweight, and easy to carry. When not in use, isolation plate 6 can be rotated to fit against side plate 2, and side plate 2 can be folded onto mounting plate 1 to achieve complete folding of the device. This design not only saves space but also facilitates storage and transportation.

[0038] The device, through its adjustable structure design, can adapt to low-pressure branch box fuse holders of different sizes, exhibiting high versatility. Simultaneously, the magnetic attraction function of the electromagnet 26 and the intelligent adjustment function of the photoelectric sensor make the installation and use of the device more convenient, helping to increase operator acceptance and promote its widespread adoption.

[0039] This device is suitable for live-line work on low-voltage branch boxes, especially in environments where multiple switches are installed in parallel. By isolating the fuse holders that require maintenance, the device can effectively avoid safety hazards caused by proximity to nearby lines and reduce the impact of frequent power outages on residential users.

[0040] In practical applications, this device significantly improves work efficiency and safety. Through precise adjustment, it can quickly adapt to different sized welding seats, reducing installation time. Simultaneously, the electromagnet's attraction function and the photoelectric sensor's intelligent detection function ensure the device remains stable during maintenance, preventing displacement or loosening.

[0041] This device, through its rational mechanical structure design and intelligent adjustment functions, solves the safety hazard problem caused by insufficient spacing between fuse holders in low-voltage branch boxes. Its portability, versatility, and convenience make it widely applicable in low-voltage live-line work. By isolating the fuse holders requiring maintenance, the device not only improves operational efficiency but also significantly reduces the risk of misoperation, providing strong protection for the safe operation of the power system.

[0042] Example 2: Refer to Figures 1 to 8 The device includes a mounting plate 1 and a side plate 2, which are connected by a first hinge 3 and a second hinge 4. The mounting plate 1 serves as the base of the device, fixed to the frame of the branch box, providing stable support. The side plate 2 can rotate up and down via hinges, facilitating the folding and unfolding of the device for easy carrying and storage. One side of the side plate 2 is connected to an isolation plate 6 via the second hinge 4. The isolation plate 6 can rotate left and right to cover or expose the welding seats, ensuring that other welding seats are not disturbed during maintenance.

[0043] The device is equipped with two adjustment mechanisms: Adjustment Mechanism One and Adjustment Mechanism Two. Adjustment Mechanism Two drives the side plate 2 to move horizontally left and right on the mounting plate 1 to accommodate welding bases of different lengths; Adjustment Mechanism One, through the forward and backward movement of the wedge block 5, adapts to welding bases of different widths. The design of the wedge block 5 allows it to be securely attached to the rear connection plate of the branch box welding base, ensuring the stability of the device. This dual-adjustment structure design allows the device to flexibly adapt to branch boxes of various sizes, avoiding installation difficulties caused by size mismatch.

[0044] An electromagnet 26 is installed on one side of the wedge-shaped block 5 to attract it behind the fusion seat, further enhancing the limiting effect of the device. A photoelectric sensor 27 is installed on the other side to detect the width of the fusion seat, providing data support for the adjustment structure and ensuring precise position adjustment of the wedge-shaped block 5. Through real-time monitoring by the photoelectric sensor, the device can automatically adjust the position of the wedge-shaped block 5 to adapt to fusion seats of different widths, significantly improving the device's intelligence level. All components of the device are made of acrylic glass. Acrylic glass is lightweight, has high mechanical strength, is easy to process, has strong impact resistance, good weather resistance, and strong flame retardancy. It is also self-extinguishing. These characteristics make the device safe, portable, and easy to install, making it particularly suitable for the complex environment of low-pressure branch boxes. The transparency of acrylic glass also allows operators to visually observe the operating status of the device, further improving the convenience and safety of operation.

[0045] The main function of the second adjustment structure is to adjust the position of the side plate 2 to accommodate welding seats of different lengths. A drive device (such as a motor or manual knob) moves the first hinge 3 and the side plate 2 horizontally left and right on the mounting plate 1. This design allows the device to flexibly adapt to branch boxes of different sizes, avoiding installation difficulties caused by size mismatch. Specifically, the drive device, through the cooperation of gears and racks, drives the side plate 2 to slide on the mounting plate 1, ensuring precise positioning of the device.

[0046] The adjustment structure 1 achieves the forward and backward movement of the wedge block 5 through the cooperation of the first slider 13, the first rack 12, and the first gear 11. Specifically, the second driving component 9 (motor or knob) drives the first connecting shaft 10 to rotate, which in turn drives the first gear 11 to rotate. Since the first rack 12 meshes with the first gear 11, the rack moves horizontally back and forth inside the side plate 2, causing the slider 13 to slide along the slide groove 14, ultimately achieving the position adjustment of the wedge block 5. The photoelectric sensor 27 detects the width of the weld base in real time and feeds the data back to the adjustment structure. When the second driving component 9 is a motor, the motor automatically adjusts the position of the wedge block 5 according to the sensor signal; when the driving component is a knob, the operator can manually adjust the position of the wedge block 5 according to the sensor reading. This design satisfies the needs of automation while retaining the flexibility of manual adjustment.

[0047] The design of side plate 2 and isolation plate 6 effectively isolates the weld bead requiring maintenance from other weld beads. By rotating isolation plate 6, the target weld bead can be exposed while other weld beads are blocked, preventing accidental operation. This isolation measure significantly improves operational safety.

[0048] The device has a compact overall structure, is lightweight, and easy to carry. When not in use, the partition plate 6 can be rotated to fit against the side plate 2, and then the side plate 2 can be folded onto the mounting plate 1 to achieve complete folding of the device. This design not only saves space but also facilitates storage and transportation.

[0049] The device, through its adjustable structure design, can adapt to fuse holders of different sizes in low-voltage branch boxes, exhibiting high versatility. Simultaneously, the magnetic attraction function of the electromagnet 26 and the intelligent adjustment function of the photoelectric sensor make installation and use more convenient, helping to improve operator acceptance and promote widespread adoption. This device is suitable for live-line work on low-voltage branch boxes, especially in environments with multiple switches installed in parallel. By isolating the fuse holder requiring maintenance, the device effectively avoids safety hazards caused by proximity to nearby lines, reducing the impact of frequent power outages on residential users. Through precise adjustment, the device can quickly adapt to fuse holders of different sizes, reducing installation time. Furthermore, the electromagnet's attraction function and the photoelectric sensor's intelligent detection function ensure the device remains stable during maintenance, preventing displacement or loosening.

[0050] Adjustment structure two enables the side plate 2 to move horizontally left and right on the mounting plate 1. This function is crucial for adapting to fuse holders of different lengths, ensuring that the device can flexibly handle the structural characteristics of various low-pressure branch boxes. Adjustment structure two comprises a first driving component 8, a second connecting shaft 22, a second bevel gear 17, a first bevel gear 25, a third connecting shaft 24, a second gear 23, a second rack 21, a connecting column 20, a second slider 19, a moving plate 7, a T-shaped slider 18, and a second photoelectric sensor 28. These components work together through precise mechanical coordination to complete the position adjustment task of the side plate 2.

[0051] The power source for the second adjustment structure is the first driving component 8, which can be a motor or a knob, depending on the application requirements. When the first driving component 8 operates, the second connecting shaft 22, fixedly connected to one side of it, begins to rotate. A second bevel gear 17 is fixedly connected to one end of the second connecting shaft 22, and this bevel gear meshes with the first bevel gear 25 through its tooth ends. This bevel gear transmission design not only changes the direction of force transmission but also ensures efficient power transmission, providing a stable driving force for subsequent mechanical movements.

[0052] A third connecting shaft 24 is fixedly connected to the bottom of the first bevel gear 25, and the bottom end of the shaft is rotatably connected inside the mounting plate 1. This design ensures the stability of the third connecting shaft 24 during rotation and provides a solid foundation for subsequent mechanical transmission. A second gear 23 is fixedly connected to the middle of the third connecting shaft 24, and this gear meshes with two symmetrically arranged second racks 21 through its tooth ends. When the third connecting shaft 24 rotates within the mounting plate 1, the second gear 23 rotates accordingly, thereby driving the two second racks 21 to move horizontally left and right.

[0053] This combination of bevel gears and rack and pinion transmission design not only efficiently transmits power but also ensures transmission accuracy and stability. The use of bevel gears changes the direction of power transmission, thereby optimizing the internal spatial layout of the device and making the entire adjustment structure more compact and efficient.

[0054] A connecting post 20 is fixedly connected to the side of the second rack 21 that is furthest away from it, and a second slider 19 is fixedly connected to the top of the connecting post 20. The outer wall of the second slider 19 is slidably connected within the second groove 15 of the mounting plate 1, ensuring that the slider remains stable during movement. This groove-slider cooperation design not only provides guidance for movement but also effectively limits the wobbling of the slider, ensuring the straightness of its movement trajectory.

[0055] Meanwhile, T-shaped sliders 18 are symmetrically fixedly connected to the bottom of the movable plate 7, and their outer walls are slidably connected within the T-shaped grooves 16 of the mounting plate 1. The design of the T-shaped grooves further enhances the stability of the movable plate 7 during movement, preventing deviation or shaking caused by external forces. This double-limiting design ensures that the movable plate 7 remains stable during horizontal movement, providing a reliable guarantee for subsequent mechanical actions.

[0056] The movable plate 7 is fixedly connected to the top of the second slider 19, and a photoelectric sensor 28 is provided on one side of it. When the second rack 21 drives the connecting column 20 and the second slider 19 to move, the movable plate 7 slides horizontally on the mounting plate 1. The movable plate 7 is connected to the side plate 2 through the first hinge 3, so its movement directly drives the side plate 2 to move horizontally left and right on the mounting plate 1.

[0057] This design allows the position adjustment of the side plate 2 to be synchronized with the movement of the movable plate 7, ensuring the coordination and consistency of the adjustment actions. Through real-time monitoring by the photoelectric sensor 28, the position change of the movable plate 7 can be accurately captured and fed back to the control system, thereby achieving precise adjustment of the position of the side plate 2.

[0058] The adjustment structure, through the horizontally movable side plate 2, can accommodate welding seats of different lengths, significantly improving the versatility of the device. This design allows the device to quickly respond to the needs of branch boxes of different sizes, reducing installation difficulties caused by equipment incompatibility. The limiting design of the T-shaped slide and the second slide ensures the stability of the movement of the moving plate 7 and the side plate 2, avoiding displacement caused by external forces. This stability is crucial for live-line work in complex environments, ensuring the safety and reliability of the device during operation.

[0059] The real-time monitoring function of photoelectric sensor 28 and the automatic adjustment capability of the motor drive make the operation of the device more convenient and efficient. Operators can quickly adjust the position of side plate 2 through the control system to adapt to different sized welding seats, significantly improving work efficiency.

[0060] When the first drive component 8 is a knob, the operator can manually adjust the position of the side plate 2 by turning the knob. This design provides flexibility to the device, enabling it to adapt to application needs in different scenarios. In particular, manual adjustment provides a reliable backup solution when automated equipment is unavailable.

[0061] The precise engagement of the first bevel gear 25, the third connecting shaft 24, the second gear 23, and the second rack 21 enables the second adjustment structure to allow the side plate 2 to move horizontally left and right, ensuring the device can adapt to welding seats of different lengths. The limiting design of the T-shaped and second slides further enhances the stability of movement, while the real-time monitoring function of the photoelectric sensor 28 supports the intelligent adjustment of the device. This design not only improves the flexibility and adaptability of the device but also ensures its stability and reliability in complex environments, providing strong technical support for low-voltage live-line work.

[0062] The cooperation between the T-shaped slider 18 and the T-shaped groove 16 limits the movement of the moving plate 7, ensuring the straightness and stability of its movement trajectory. This design not only improves the mechanical precision of the device but also enhances its reliability in complex environments. The smooth movement of the moving plate 7 ensures accurate positioning of the side plate 2, thus adapting to welding seats of different lengths.

[0063] A photoelectric sensor 28 is installed on one side of the movable plate 7. This sensor detects the length of the welding base in real time and feeds the data back to the control system. When the first driving component 8 is a motor, the motor automatically adjusts the position of the movable plate 7 according to the sensor signal, thereby driving the side plate 2 to move to the appropriate position. This intelligent adjustment function enables the device to quickly adapt to welding bases of different sizes, significantly improving work efficiency.

[0064] When the first drive component 8 is a knob, the operator can manually adjust the position of the side plate 2 by rotating the knob. This design provides flexibility to the device, allowing it to adapt to application needs in different scenarios. For example, in highly automated environments, motor drive can be selected; while in situations requiring fine manual adjustment, it can be switched to knob mode.

[0065] The design of Adjustment Structure II fully considers the actual operational needs of the low-voltage branch box. In environments where multiple switches are installed in parallel, the spacing between fuse holders may vary depending on the equipment model and installation method. Through the flexible adjustment function of Adjustment Structure II, the device can adapt to fuse holders of various sizes, ensuring reliable isolation protection during maintenance. Adjustment Structure II, through the horizontal movement of side plate 2, can adapt to fuse holders of different lengths, significantly improving the device's versatility. The limiting design of the T-slot and the second slot ensures the stability of the movement of the moving plate 7 and side plate 2, preventing displacement caused by external forces. The real-time detection function of photoelectric sensor 28 and the automatic adjustment capability driven by the motor make the device's operation more convenient and efficient. The knob mode provides convenience for manual adjustment in special scenarios, enhancing the device's practicality.

[0066] The second adjustment structure, through its intelligent adjustment function, provides flexible, stable, and reliable side plate position adjustment capabilities for the insulation isolation device of the low-voltage live-line working branch box. Its intelligent photoelectric sensor feedback mechanism and flexible manual / automatic switching function enable the device to adapt to the structural characteristics of various low-voltage branch boxes, significantly improving operational efficiency and safety. This design not only meets the high requirements of modern power systems for equipment maintenance but also provides solid technical support for the promotion and application of the device.
