Description

Technical Field

[0001] This invention relates to the field of cable branch box technology, specifically a cable branch box and its fireproof, explosion-proof, and pressure-relief structure. Background Technology

[0002] With the accelerated construction of my country's new power system, the continuous deepening of urban and rural power distribution network transformation, and the rapid rise of the new energy industry, the power distribution system is transforming towards intelligence, efficiency, and safety. As the core carrier of power transmission, the scale and coverage of cable laying continue to expand. As a key node device in the power distribution network, cable branch boxes undertake the important functions of cable line branching, switching, power distribution, and equipment protection. They have been widely used in urban power distribution networks, industrial parks, new energy power plants, transportation hubs, and rural power grid transformation, becoming one of the important basic equipment to ensure the stable operation of the power system.

[0003] Currently, cable branch boxes and their fireproof and explosion-proof pressure relief structures are unable to provide efficient protection, making them prone to combustion and explosion, thus posing safety hazards. Improvements are needed. Summary of the Invention

[0004] To address the problems in the prior art, the present invention provides a cable branch box and its fireproof, explosion-proof, and pressure-relief structure.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a low-voltage cable branch box, including a branch box structure, a door panel is hinged to the branch box structure by a hinge rod, and a handle is fixedly provided on the door panel;

[0006] The branch box structure is used for low-voltage cable protection and connection work. The branch box structure includes a support base, on which a ventilated cabinet is fixedly connected. Safety components are fixedly installed inside the ventilated cabinet, and a top plate is fixedly installed on the top of the ventilated cabinet.

[0007] Specifically, the safety component includes a first docking safety mechanism and a second docking safety mechanism. The first and second docking safety mechanisms have identical structures and are symmetrically arranged. The branch box structure provides protection for the safety component, while the ventilated cabinet supports and protects the safety component. The ventilated cabinet is fixed to the support base for support, and the door panel is hinged to the branch box structure for internal protection. The safety component is equipped with a combination of the first and second docking safety mechanisms, providing multi-layer protection. The dual switches enhance safety performance.

[0008] Specifically, the second docking safety mechanism includes an insulating protection plate, on the top of which a main control cabinet is fixedly installed. An instrument panel is electrically connected to the main control cabinet, and a docking protection unit is electrically connected to the instrument panel. The structure of the second docking safety mechanism facilitates protective docking operations. The main control cabinet, instrument panel, and docking protection unit are electrically connected to achieve power-on protection. The protection module can control the electrical connection with the first and second guide busbars by rotating. The rotating disk controls the rotation of the threaded rod, causing two insulating sliding blocks to move on the guide slot seat, thereby pushing the first and second docking units to move and align with the first and second guide busbars. This connects the first and second guide busbars to the docking connector through the protection module, thereby improving safety and stability.

[0009] Specifically, the docking protection unit includes a connector, a busbar groove is fixedly connected to the connector, a docking connection seat is electrically connected to the busbar groove, and a docking protection module is electrically connected to the docking connection seat.

[0010] Specifically, the docking protection module includes an insulating protective block, on which a first guide bus and a second guide bus are fixedly mounted, and an insulating explosion-proof plate is fixedly mounted. A protection module is installed on the insulating protective block, and the protection module is docked with the first guide bus and the second guide bus. The connection between the first guide bus and the protection module is controlled through the protection module.

[0011] Specifically, the protection module includes a rotating disk, a threaded rod fixedly connected to the rotating disk, an insulating sliding block threadedly connected to the threaded rod, the insulating sliding block slidably connected to the guide slot seat, a first docking unit hinged on the insulating sliding block, the first docking unit being supported at the bottom by a protective insulating sleeve block, and the rear end of the protective insulating sleeve block being supported and protected by a second docking unit.

[0012] Specifically, the first docking unit includes a first outer insulating conductive base, a first telescopic conductive block is telescopically connected to the first outer insulating conductive base, a first guiding docking link is fixedly connected to the first telescopic conductive block, a first horizontal round rod is fixedly provided on the first guiding docking link and the first outer insulating conductive base, a first pushing guide rod is hinged on the first horizontal round rod, and the bottom of the first pushing guide rod is hinged to the first hinged link.

[0013] Specifically, the second docking unit includes a second outer insulating conductive seat, a second telescopic conductive block telescopically connected to the second outer insulating conductive seat, a second guiding docking link fixedly connected to the second telescopic conductive block, a second horizontal round rod fixedly connected to the second guiding docking link, a second hinged link hinged to the second horizontal round rod, and a second push guide rod hinged to the lower end of the second hinged link. The connecting seat in the docking protection unit is electrically connected to the busbar trough, the busbar trough is electrically connected to the docking communication seat, the upper end of the docking communication seat is electrically connected to the docking protection module, the insulating protective block is fixed to the insulating explosion-proof plate, and the protection module can rotate on the insulating explosion-proof plate to control the connection with the first and second guiding busbars. The bottom of the protection module is electrically connected to the docking communication seat. When docking is required, the rotating disk is rotated, and the rotating disk drives the threaded rod to rotate, so that the threaded rod drives the two insulating sliding blocks to slide and adjust on the guide slot seat, changing the first docking unit. The first and second docking units are fixedly installed with the protective insulating sleeve block for insulation protection. When the insulating sliding block moves, it drives the first hinged connecting rod to move, which in turn drives the first push guide rod to move. This causes the first push guide rod to drive the first horizontal round rod to move, which in turn controls the movement of the first guide docking connecting rod and the first telescopic conductive block. The first telescopic conductive block slides on the first outer insulating conductive seat, thereby causing the first guide docking connecting rod to move longitudinally and connect with the second guide busbar. When the second insulating sliding block moves, it drives the second push guide rod to move, which in turn drives the second hinged connecting rod to push the second horizontal round rod. This causes the second horizontal round rod to drive the movement of the second telescopic conductive block and the second guide docking connecting rod. The second telescopic conductive block slides on the second outer insulating conductive seat, controlling the longitudinal movement of the second guide docking connecting rod, so that the second guide docking connecting rod is connected and aligned with the first guide busbar, enabling energization or de-energization.

[0014] Specifically, the bottom of the second push guide rod is connected to a second insulating sliding block, and the first hinged connecting rod is fixedly connected to the insulating sliding block. The first push guide rod controls the movement of the first horizontal round rod by pushing, so that the first guide docking connecting rod drives the first telescopic conductive block to extend and retract on the first outer insulating conductive seat. The second hinged connecting rod controls the extension and retraction of the second horizontal round rod by moving, so that the second guide docking connecting rod drives the second telescopic conductive block to extend and retract on the second outer insulating conductive seat for adjustment.

[0015] Specifically, the bottoms of the first telescopic conductive block and the second outer insulating conductive seat are electrically connected to the docking connection seat, and the first guide docking link and the second guide docking link are aligned and connected with the bottoms of the first guide busbar and the second guide busbar through telescopic connection.

[0016] The beneficial effects of this invention are:

[0017] First, this invention protects the safety components through the branch box structure. The ventilated cabinet supports and protects the safety components, and the ventilated cabinet is fixed to the support base to achieve support. The door panel is rotatably connected to the branch box structure through a hinge to provide internal protection. The safety components are equipped with a combination of a first docking safety mechanism and a second docking safety mechanism to provide multi-layer protection. The dual switch improves the safety protection performance.

[0018] Second, the present invention facilitates protective docking through the structural design of the second docking safety mechanism. The main control cabinet, instrument panel, and docking protection unit are electrically connected to achieve power-on protection. The protection module can control the electrical connection with the first guide bus and the second guide bus by rotation. The rotating disk controls the rotation of the threaded rod, causing the two insulating sliding blocks to move on the guide slot seat, thereby pushing the first docking unit and the second docking unit to move and align with the first guide bus and the second guide bus. This connects the first guide bus and the second guide bus to the docking connection seat through the protection module, thereby improving safety and stability. Attached Figure Description

The protection module 22 can rotate on the insulating explosion-proof plate 23, thereby controlling the connection with the first guide bus 19 and the second guide bus 20. The bottom of the protection module 22 is electrically connected to the docking connection seat 18. When docking connection is required, the rotating disk 24 is rotated. The rotating disk 24 drives the threaded rod 25 to rotate, so that the threaded rod 25 drives the two insulating sliding blocks 27 to slide and adjust on the guide slot seat 26, changing the first docking... Unit 28 and the second docking unit 30 are fixedly installed with the protective insulating sleeve block 29 for insulation protection. When the insulating sliding block 27 moves, it drives the first hinge connecting rod 34 to move, which in turn pushes the first push guide rod 35 to move.

The first telescopic conductive block 32 slides on the first outer insulating conductive seat 33, thereby enabling the first guiding docking... The connecting rod 31 moves longitudinally to connect with the second guide busbar 20. When the second insulating sliding block 27 moves, it drives the second push guide rod 42 to move, so that the second hinged connecting rod 41 drives the second horizontal round rod 39 to push. The second horizontal round rod 39 drives the second telescopic conductive block 38 and the second guide docking connecting rod 37 to move.

[0045] The working principle is as follows: During use, the branch box structure 1 is sealed and protected by the door panel 2. The door panel 2 is hinged to the branch box structure 1 by the hinge rod 3, allowing it to be flipped. A handle 4 is fixed on the door panel 2 for easy control of the flipping operation. The top plate 5, ventilation cabinet 7, and support base 8 inside the branch box structure 1 are fixed to protect the safety component 6.

The upper end of the docking connection seat 18 is electrically connected to the docking protection module 15. The insulating protective block 21 is fixed to the insulating explosion-proof plate 23. The protection module 22 can rotate on the insulating explosion-proof plate 23, thereby controlling the connection with the first guide bus 19 and the second guide bus 20. The bottom of the protection module 22 is electrically connected to the docking and connecting seat 18. When docking and connection are required, the rotating disk 24 is rotated, which drives the threaded rod 25 to rotate. This causes the threaded rod 25 to drive the two insulating sliding blocks 27 to slide and adjust on the guide slot seat 26, changing the positions of the first docking unit 28 and the second docking unit 30. The first docking unit 28 and the second docking unit 30 are fixedly set with the protective insulating sleeve block 29 to perform insulation protection. When the insulating sliding block 27 moves, it drives the first hinge connecting rod 34 to move, pushing the first push guide rod 35 to move. This causes the first push guide rod 35 to drive the first horizontal round rod 36 to push, so that the first horizontal round rod 36 controls the first guide docking connecting rod 31. The first telescopic conductive block 32 moves and slides on the first outer insulating conductive seat 33, thereby causing the first guide docking link 31 to move longitudinally and connect with the second guide busbar 20. When the second insulating sliding block 27 moves, it drives the second push guide rod 42 to move, causing the second hinge link 41 to drive the second horizontal round rod 39 to push. The second horizontal round rod 39 drives the second telescopic conductive block 38 and the second guide docking link 37 to move.
