[0020] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0021] The utility model provides an electrical circuit protection device, such as Figures 1-4 As shown, the electrical line protection device includes: a mounting frame 2 arranged in a distribution box body 1; a limit rod 5 installed on the mounting frame 2 for supporting the electric wires; an isolation plate 6 fixed on the limit rod 5 for isolating different electric wires; a wire arrangement port 8 arranged on the mounting frame 2, a block being detachably installed in the wire arrangement port 8; and a cooling component installed on the mounting frame 2, the cooling component being used to increase the air flow rate in the distribution box body 1.
[0022] In this embodiment, the distribution box body 1 serves as the basic structure of the entire device. The distribution box body 1 provides a protective enclosed environment for the internal circuits and equipment. The limiting rod 5 is used to support the wires, ensuring that the wires are in fixed positions, avoiding random swinging or cross-winding, thus keeping the circuits clean and orderly, reducing the phenomenon of messy cables, reducing the risk of electromagnetic interference and physical wear, improving the stability and reliability of the circuits. The partition board 6 prevents direct contact between the wires, enhancing the insulation performance, and is also conducive to the heat dissipation of the wires, reducing the safety hazards caused by overheating. The temperature reduction component is used to increase the air flow rate inside the distribution box, promote the heat dissipation of the wires, prevent the wires from overheating, and reduce the risk of safety accidents such as fires caused by overheating.
[0023] In a further preferred embodiment of the present utility model, the temperature reduction component includes a mounting plate 13 installed on the mounting frame 2; a blower 14 and an exhaust duct 15 fixed to the top of the mounting plate 13. The exhaust duct 15 is connected to the exhaust end of the blower 14, and the intake end of the blower 14 extends outside the distribution box body 1; a plurality of branch ducts 16 fixed to the exhaust duct 15, and a plurality of the branch ducts 16 can all extend to the bottom of the mounting plate 13.
[0024] In this embodiment, the mounting plate 13 serves as a support platform for the blower 14 and the exhaust duct 15. The blower 14 sucks the cold air outside the distribution box through its intake end, and after being accelerated by the impeller inside the blower 14, it is discharged through the exhaust end, introducing the cold air outside the distribution box into the box and accelerating the discharge of the hot air inside the box, thereby effectively reducing the temperature inside the distribution box and protecting the wires from overheating damage. The design of the exhaust duct 15 and the branch ducts 16 makes the exhaust effect of the blower 14 more uniform and can cover a wider area inside the distribution box.
[0025] In a further preferred embodiment of the present utility model, the mounting frame 2 is provided with ventilation openings, and a metal isolation net 4 is arranged inside the ventilation openings. A plurality of fixing bolts 3 are threadedly installed on the mounting frame 2, and a plurality of the fixing bolts 3 are all threadedly connected to the distribution box body 1.
[0026] In this embodiment, the ventilation openings allow a certain degree of air exchange between the inside and outside of the distribution box, which helps to discharge the hot air inside the distribution box and is also conducive to preventing damage to electrical components caused by excessive humidity inside the box. The metal isolation net 4 is used to prevent external dust, insects, rodents and other sundries from entering the inside of the distribution box through the ventilation openings, keeping the inside of the distribution box clean and the electrical components safe. By tightly connecting the mounting frame 2 to the distribution box body 1 through the fixing bolts 3, not only the stability of the mounting frame 2 is improved, but also the subsequent maintenance and repair work is facilitated. When it is necessary to replace or adjust the components on the mounting frame 2, only need to loosen the fixing bolts 3 to easily remove the mounting frame 2, which greatly saves the maintenance time and cost.
[0027] In a further preferred embodiment of the present utility model, the number of wire arranging ports 8 is the same as the number of power supply wires connected into the distribution box body 1. Two electric telescopic rods 9 are installed on the mounting frame 2, and the output rods of the two electric telescopic rods 9 are both fixed with the same abutting plate 10. A support plate 11 is provided on the mounting frame 2, and the abutting plate 10 and the support plate 11 are respectively located at the top and bottom of a plurality of the wire arranging ports 8.
[0028] In this embodiment, the fact that the number of wire arranging ports 8 is the same as the number of power supply wires connected into the distribution box body 1 ensures that each power supply wire can be connected and fixed through a dedicated wire arranging port 8, avoiding chaos and crossing, and improving the neatness and aesthetics of wire arrangement. The electric telescopic rod 9 can perform telescopic movement according to needs, thereby driving the abutting plate 10 to move up and down, which can conveniently fix and press the power supply wire, improving the stability and reliability of wire arrangement.
[0029] In a further preferred embodiment of the present utility model, rubber pads 12 are fixed on the bottom of the abutting plate 10 and the top of the support plate 11 respectively. The two rubber pads 12 can be in contact with each other, and card slots are provided on one side of the two rubber pads 12 close to each other.
[0030] In this embodiment, as a soft material, the rubber pad 12 has good elasticity and wear resistance. When the abutting plate 10 and the support plate 11 approach each other, the two rubber pads 12 can be in contact with each other to form a soft buffer layer, so that the power supply wire is not easily loosened or fallen off when subjected to external force, and also plays a role in shock absorption and noise reduction, protecting the power supply wire from mechanical impact and vibration. At the same time, the softness of the rubber pad 12 can also effectively prevent the power supply wire from being deformed or damaged due to long-term compression. The addition of the card slots further improves the fixing effect of the power supply wire, making the layout of the power supply wire in the distribution box more neat and orderly.
[0031] In a further preferred embodiment of the present utility model, threaded rods are fixed on a plurality of the limiting rods 5, and the plurality of threaded rods are all threadedly installed on the mounting frame 2. Shock-absorbing sleeves 7 that can be in contact with the wires are fixedly sleeved outside the plurality of limiting rods 5.
[0032] In this embodiment, the design of the threaded rod enables the limiting rod 5 to be firmly fixed on the mounting frame 2 through threaded connection, not easily loosened or fallen off, and the position and height of the limiting rod 5 can be conveniently adjusted to adapt to wires of different specifications and lengths. The main function of the shock-absorbing sleeve 7 is to relieve the vibration and impact generated by the wire due to external force. The direct contact between the shock-absorbing sleeve 7 and the wire also increases the friction between the wire and the limiting rod 5, further preventing the displacement or falling off of the wire.
[0033] In a further preferred embodiment of the present utility model, the mounting bracket 2 is composed of a metal bracket 17 and an insulating coating 18. The metal bracket 17 is detachably mounted inside the distribution box body 1, and the insulating coating 18 is provided on the outer wall of the metal bracket 17.
[0034] In this embodiment, the metal bracket 17 has the advantages of high strength, corrosion resistance, wear resistance, etc. These characteristics enable the metal bracket 17 to withstand large mechanical stresses and environmental erosion, maintaining a stable structure and performance. The insulating coating 18 has good insulating properties and high temperature resistance. Its main function is to prevent the metal bracket 17 from coming into direct contact with the electrical components or wires inside the distribution box, thereby avoiding potential safety hazards such as electrical short circuits or electric shocks. The insulating coating 18 can also protect the metal bracket 17 from corrosion and oxidation, extending its service life.
[0035] In a further preferred embodiment of the present utility model, the colors of the plurality of limiting rods 5 are respectively the same as the outer skin colors of the ground wire, neutral wire, and live wire inside the distribution box body 1. A dustproof cover is detachably mounted at the air inlet end of the fan 14.
[0036] In this embodiment, the color marking of the limiting rods 5 enables the operator to quickly identify and correspond to the correct wire type when installing or maintaining the wires, improving the accuracy and efficiency of the operation. The introduction of the color marking reduces the risk of electrical accidents caused by misoperation and also simplifies the operation process, enabling non-professional personnel to perform basic electrical maintenance work under guidance. The main function of the dustproof cover is to protect the fan 14 from dust and debris, extend the service life of the fan 14, and ensure its normal operation.
[0037] In summary, compared with the related art, the present device supports each electrical component through the setting of the mounting bracket 2, facilitating the unified installation and disassembly of the electrical components. By setting the cooling component, the air flow rate inside the distribution box body 1 can be adjusted, thereby increasing the heat exchange efficiency and enabling the electrical components to dissipate heat faster. By setting the limiting rods 5, the wires can be isolated and limited, and by setting the partition plate 6, the mutual contact between the wires can be prevented from affecting the heat dissipation effect, increasing the safety of the device.
