Description

Technical Field

[0001] This utility model relates to the field of junction box technology, specifically to a junction box aerosol fire extinguisher. Background Technology

[0002] A distribution box, in a power system, is a box used to distribute electrical energy, protect electrical appliances, and serve as a junction point for connecting lines during the process of transmitting power to various electrical devices. It typically contains electrical components such as switches, sockets, fuses, and circuit breakers. Distribution boxes are placed between the electricity meter and the electrical equipment. In the event of an electrical fault, the distribution box can promptly disconnect the faulty circuit, preventing the fault from escalating and affecting the entire power grid. However, due to the large number of internal electrical components, if a short circuit causes a fire, it is difficult for outside personnel to respond immediately. Even if they do, they can only find non-conductive carbon dioxide or dry powder fire extinguishers, resulting in low firefighting efficiency and the inability to extinguish the fire immediately, potentially causing greater property damage. Therefore, aerosol fire extinguishers are commonly installed in distribution boxes for immediate fire suppression. The existing technology has the following problems:

[0003] Because the existing aerosol fire extinguishers in the distribution box are installed inside the box by bolts, once a fire occurs, the aerosol fire extinguisher will automatically activate and be used up. When it needs to be replaced, tools must be used to disassemble it and install a new aerosol fire extinguisher. The disassembly and assembly process is time-consuming and affects the replacement efficiency. Utility Model Content

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand

[0022] Understood. The present invention will now be further described in conjunction with specific implementation methods.

[0023] like Figure 1 , Figure 2 , Figure 3As shown, this utility model provides a junction box aerosol fire extinguisher, including a junction box body 1, a door 2 hinged to the front of the junction box body 1, several heat dissipation holes 3 on the left and right sides of the junction box body 1, a wire inlet hole 4 penetrating the inner cavity on the left side of the junction box body 1, several terminals 11 evenly fixedly installed on the left rear end of the inner wall of the junction box body 1, a relay 12 fixedly installed on the right rear end of the inner wall of the junction box body 1, and an aerosol fire extinguisher mechanism 13 provided on the top of the inner wall of the junction box body 1. The inner wall of the housing 1 has four bolt holes 14 in a rectangular array at the top. The aerosol fire extinguisher mechanism 13 includes a mounting plate 131. Extension plates 133 are fixedly installed on both the left and right sides of the mounting plate 131. Two fixing bolts 134 are provided at the bottom of each of the two extension plates 133. The top of the fixing bolts 134 passes through to the top of the extension plate 133 and is threaded to the bolt holes 14. Two positioning mechanisms 135 are provided below the mounting plate 131. The aerosol fire extinguisher body 132 is provided between the opposite surfaces of the two positioning mechanisms 135.

[0024] Different lines can pass through the inlet hole 4 into the inner cavity of the junction box 1 and connect to the terminal block 11. At the same time, the junction box 1 can dissipate heat through the heat dissipation hole 3. During routine maintenance, the inner cavity of the junction box 1 can be observed by opening the box door 2. The relay 12 can trip in the event of a short circuit. The integrated aerosol fire extinguisher mechanism 13 is installed at the top of the inner cavity of the junction box 1. Once a fire occurs in its inner cavity, the flame will spread upward. When the temperature exceeds the set value, the built-in probe of the aerosol fire extinguisher body 132 included in the aerosol fire extinguisher mechanism 13 will send a signal to the built-in controller. The controller will activate the fire extinguishing system and release the aerosol fire extinguishing agent to extinguish the fire. During the initial installation, the mounting plate 131 can be fixed to the bottom of the inner wall of the junction box 1 by using the fixing bolt 134 to pass through the extension plate 133 and threaded to the bolt hole 14. Then, the aerosol fire extinguisher body 132 can be placed between the two positioning mechanisms 135 for positioning.

[0025] like Figure 4As shown, a clamping groove 1311 is provided at the bottom of the mounting plate 131. A positive and negative threaded rod 1312 is movably installed on the right side of the inner wall of the clamping groove 1311. The left end of the positive and negative threaded rod 1312 extends through to the left side of the mounting plate 131 and is fixedly installed with a disassembly knob 1313. The left and right sides of the outer wall of the positive and negative threaded rod 1312 are respectively provided with threaded walls with opposite threads. A movable plate 1314 is threadedly installed on the outer wall of both threaded walls. The front and rear sides of the two movable plates 1314 overlap with the front and rear sides of the inner wall of the clamping groove 1311, respectively. A suspension clamping plate 1315 is fixedly installed at the bottom of the two movable plates 1314. A dustproof baffle 1316 is fixedly installed on the opposite side of the two suspension clamping plates 1315. The top of the suspension clamping plate 1315 overlaps with the bottom of the mounting plate 131. The top of the dustproof baffle 1316 and the top of the suspension clamping plate 1315 are on the same horizontal line.

[0026] During positioning, simply turn the disassembly knob 1313 to rotate the positive and negative threaded rod 1312 in the clamping groove 1311. By using the threaded walls of the opposite threads on the left and right sides of the outer wall of the positive and negative threaded rod 1312 to connect with the threads of the moving plate 1314, the two suspension clamps 1315 can be controlled to move closer together to clamp and position the left and right sides of the aerosol fire extinguisher body 132. When the dust baffle 1316 moves inward with the suspension clamps 1315 to clamp the left and right sides of the aerosol fire extinguisher body 132, the wider dust baffle 1316 will block the upper clamping groove 1311 for protection, and the middle part of the clamping groove 1311 will be blocked by the top of the aerosol fire extinguisher body 132, thereby preventing a large amount of debris and floating objects from entering the clamping groove 1311 during fire extinguishing and affecting the positive and negative threaded rod 1312.

[0027] like Figure 5 As shown, each positioning mechanism 135 includes a lifting control plate 1351. The opposing surfaces of the two lifting control plates 1351 are on the same vertical line as the opposing surfaces of the two suspension clamps 1315. Each opposing surface of the two lifting control plates 1351 has a lifting groove 1352. A lifting threaded rod 1353 is movably installed on the bottom of the inner wall of the lifting groove 1352. The bottom end of the lifting threaded rod 1353 extends through to the bottom of the lifting control plate 1351 and is fixedly mounted with a lifting clamping knob 1354. The outer wall of the 3 is threaded with a lifting block 1355. The opposite faces of the two lifting blocks 1355 are fixedly installed with positioning top plates 1356. The top of the positioning top plate 1356 overlaps with the bottom of the aerosol fire extinguisher body 132. The bottom of the positioning top plate 1356 is fixedly installed with a protective side plate 1357. The opposite faces of the two positioning top plates 1356 overlap with the opposite faces of the two lifting control plates 1351. The opposite faces of the two protective side plates 1357 are on the same vertical line as the opposite faces of the two positioning top plates 1356.

[0028] After the two suspension plates 1315 clamp the aerosol fire extinguisher body 132, to prevent the aerosol fire extinguisher body 132 from falling downwards, simply rotate the lifting clamping knob 1354 below the lifting control plate 1351 at the bottom of the two suspension plates 1315 simultaneously. This will drive the lifting threaded rod 1353 in the lifting slide 1352 to rotate. The threaded connection between the lifting threaded rod 1353 and the lifting block 1355 controls the positioning top plate 1356 to move the protective side plate 1357 upwards, thus pressing and fixing the bottom of the aerosol fire extinguisher body 132, completing the process. The stable installation of the aerosol fire extinguisher body 132, along with the fact that the lifting slide 1352 can be shielded by the aerosol fire extinguisher body 132 and the protective side plate 1357, can also prevent floating objects from affecting the lifting threaded rod 1353 during fire extinguishing. Similarly, reversing the lifting clamping knob 1354 can move the positioning top plate 1356 downward, and reversing the disassembly knob 1313 can separate and move the two suspension clamps 1315, releasing the clamping and fixing of the aerosol fire extinguisher body 132, thereby allowing the activated aerosol fire extinguisher body 132 to be quickly disassembled and replaced.

[0029] The working principle of the aerosol fire extinguisher in this distribution box will be explained in detail below.

[0030] like Figure 1-5As shown, different lines can pass through the inlet hole 4 into the inner cavity of the junction box 1 and connect to the terminal block 11. The junction box 1 can also dissipate heat through the ventilation holes 3. During routine maintenance, the inner cavity of the junction box 1 can be observed by opening the box door 2. The relay 12 can trip in the event of a short circuit. The integrated aerosol fire extinguisher mechanism 13 is installed at the top of the inner cavity of the junction box 1. Once a fire occurs inside, the flames will spread upwards. When the temperature exceeds the set value, the built-in probe of the aerosol fire extinguisher body 132 included in the aerosol fire extinguisher mechanism 13 will send a signal to the built-in controller. The controller will then activate the fire extinguishing system, releasing the aerosol extinguishing agent to extinguish the fire. During initial installation, the mounting plate 1 can be... 31. By using the fixing bolt 134 to pass through the extension plate 133 and threadedly connect it to the bolt hole 14, the mounting plate 131 is fixed to the bottom of the inner wall of the junction box 1. Then, the aerosol fire extinguisher body 132 can be placed between the two positioning mechanisms 135 for positioning. During positioning, simply turn the disassembly knob 1313 to drive the positive and negative threaded rod 1312 in the clamping slide 1311 to rotate. By using the threaded walls of the opposite threads on the left and right sides of the outer wall of the positive and negative threaded rod 1312 to connect with the threaded connection of the moving plate 1314, the two suspension clamps 1315 can be controlled to move closer together, clamping and positioning the left and right sides of the aerosol fire extinguisher body 132. At the same time, the aerosol fire extinguisher body 132 will clamp the middle part. The clamping grooves 1311 are shielded, and the exposed clamping grooves 1311 on both sides are shielded by dustproof baffles 1316, thus preventing a large amount of debris and floating objects from entering the clamping grooves 1311 during fire extinguishing and affecting the positive and negative threaded rods 1312. At the same time, after the two suspension plates 1315 clamp the aerosol fire extinguisher body 132, in order to prevent the aerosol fire extinguisher body 132 from falling downward, simply rotate the lifting clamping knob 1354 below the lifting control plate 1351 at the bottom of the two suspension plates 1315. This will drive the lifting threaded rod 1353 in the lifting groove 1352 to rotate. The threaded connection between the lifting threaded rod 1353 and the lifting block 1355 can control the positioning top plate 135. 6. Move the protective side plate 1357 upward to press and fix the bottom of the aerosol fire extinguisher body 132, thus completing the stable installation of the aerosol fire extinguisher body 132. At the same time, the lifting slide 1352 can be shielded by the aerosol fire extinguisher body 132 and the protective side plate 1357, which can also prevent floating objects from affecting the lifting threaded rod 1353 during fire extinguishing. Similarly, reversing the lifting clamping knob 1354 will move the positioning top plate 1356 downward, and reversing the disassembly and assembly knob 1313 will separate and move the two suspension clamps 1315 from each other, releasing the clamping and fixing of the aerosol fire extinguisher body 132, so that the aerosol fire extinguisher body 132 that has been triggered can be quickly disassembled and replaced.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
