Description

Technical Field

[0001] This invention relates to the field of outdoor communication cabinets, and more specifically to a high-strength explosion-proof outdoor communication cabinet. Background Technology

[0002] High-strength explosion-proof outdoor communication cabinets are metal containers used in outdoor environments to store and protect electronic equipment. They possess multiple characteristics such as explosion resistance and corrosion resistance. They are primarily used to store and protect critical equipment in telecommunications, communications, and energy sectors. This type of communication cabinet offers several advantages: High protection: Utilizing special protective materials and featuring a bottom sealing strip, it effectively isolates equipment from wind and sand, providing reliable protection even in extremely harsh outdoor conditions. Explosion-proof: Through reinforced cabinet materials and fixing methods, it possesses excellent shock and explosion resistance, preventing equipment damage or failure caused by external factors. Long lifespan: The cabinet is made of corrosion-resistant materials, and the surface coating is treated strictly according to relevant standards, ensuring long-term reasonable outdoor use. Stability: The internal temperature of the cabinet is stably controlled, providing a comfortable operating environment unaffected by climate changes. Flexibility: The internal space of the cabinet can be flexibly configured, allowing for the adjustment or installation of various equipment and cables as needed.

[0003] However, when existing outdoor communication cabinets are in use, because they are usually sealed and have relatively small internal spaces, they are prone to generating heat, water vapor, and other gaseous substances after long-term operation. If these gases accumulate inside the cabinet and are not discharged in time, they may lead to a high concentration of oxygen. Once exposed to a source of fire or an electric arc, this could cause an explosion. Therefore, when the oxygen concentration inside an outdoor communication cabinet increases after prolonged use, it cannot automatically and quickly connect the inside of the cabinet with the outside to reduce the oxygen concentration inside the cabinet, which will create a potential explosion hazard inside the cabinet. Summary of the Invention

[0018] (2) By setting an adjustment part at the top inside the communication cabinet, the present invention can drive the power-off frame to descend and squeeze the switch on the outer surface of the electrical components when the adjustment part is running, so as to automatically cut off the power to the communication cabinet, thereby preventing the communication cabinet from being kept powered when the oxygen concentration inside the communication cabinet is high, avoiding the occurrence of electric arc that could cause the communication cabinet to explode, thus effectively playing an explosion-proof role.

[0019] (3) By setting control buttons on both sides inside the communication cabinet, the control buttons will be squeezed when the limit plate comes into contact with the inner surface of the communication cabinet, thereby energizing the warning light strip.

[0029] Please see Figures 1-6 As shown, the present invention is a high-strength explosion-proof outdoor communication cabinet, comprising: a protective mechanism 1 and an explosion-proof mechanism 2, wherein the explosion-proof mechanism 2 is fixedly installed inside the protective mechanism 1;

[0033] The transmission unit 24 has a support frame 241 inside. The upper and lower ends of the support frame 241 are symmetrically welded with limit sleeves 245. Limit slides 246 are opened in the middle of both sides of the limit sleeves 245. The center of the limit sleeves 245 is rotatably engaged with the transmission sprocket shaft 244. The outer surface of the transmission sprocket shaft 244 is meshed with a second transmission chain 243. The outer surface of the transmission sprocket shaft 244 at the top of the support frame 241 is meshed with a first transmission chain 242.

[0034] The protective mechanism 1 has a communication cabinet 112 inside. The front of the communication cabinet 112 is rotatably installed with a cabinet door 15. The top center of the communication cabinet 112 is fixedly installed with a first filter plate 17. The top of the communication cabinet 112 is fixedly installed with a protective cover 18. The upper surface of the protective cover 18 is fixedly installed with a solar panel 19. The center of both sides of the communication cabinet 112 is provided with a snap-fit ​​groove 11.

[0035] The upper part of both sides of the communication cabinet 112 is provided with a plug-in slot 110. A support frame 13 is fixedly installed inside the communication cabinet 112. An electrical component 111 is fixedly installed on the upper part of the support frame 13. Oxygen concentration sensors 14 are evenly fixedly installed on both sides of the support frame 13. A transmission rod 16 is symmetrically rotated and snapped onto one side of the inside of the communication cabinet 112. The outer surfaces of the upper and lower ends of the transmission rod 16 are fixedly installed with first transmission sprockets 12.

[0036] The protective top plate 237 is slidably inserted into the upper outer surface of the communication cabinet 112 through the insertion slot 110. One end of the protective top plate 237 inside the second connecting part 21 and the first connecting part 23 is interlocked with each other inside the communication cabinet 112. A gap is provided between the protective cover 18 and the communication cabinet 112. The protective side plate 232 is interlocked with both sides of the communication cabinet 112 through the interlocking slot 11.

[0037] Through the above technical solution, the protective top plate 237 can be slidably inserted into the upper outer surface of the communication cabinet 112 through the insertion groove 110, which facilitates the sliding of the protective top plates 237 away from each other, thereby releasing oxygen inside the communication cabinet 112. One end of the protective top plate 237 inside the second connecting part 21 and the first connecting part 23 is interlocked with each other inside the communication cabinet 112, thereby achieving a sealing effect. A gap is provided between the protective cover 18 and the communication cabinet 112, thereby achieving a ventilation and heat dissipation effect. The protective side plate 232 is interlocked with both sides of the communication cabinet 112 through the interlocking groove 11, thereby facilitating the sealing of the sides of the communication cabinet 112 by the protective side plate 232.

[0038] One end of the tensioning torsion spring 221 is fixedly connected to the bottom surface of the limiting horizontal plate 225. The middle part of the limiting horizontal plate 225 is threadedly connected to the threaded rod 222. The bottom of the power-off frame 223 slides in contact with the upper outer surface of the snap-fit ​​groove 11. The transmission gear plate 236 is slidably inserted into both ends of the support frame 241 through the limiting sleeve 245. The transmission gear plate 236 is slidably snapped into the limiting slide 246 through the limiting snap-fit ​​block 233.

[0039] Through the above technical solution, one end of the tension torsion spring 221 is fixedly connected to the bottom surface of the limiting horizontal plate 225, the middle part of the limiting horizontal plate 225 is threadedly connected to the threaded rod 222, the bottom of the power-off frame 223 slides in contact with the upper outer surface of the snap-fit ​​groove 11, and the transmission tooth plate 236 slides into the two ends of the support frame 241 through the limiting sleeve 245, thereby limiting the sliding of the two ends of the protective side plate 232. The transmission tooth plate 236 slides into the limiting slide 246 through the limiting block 233, which can ensure that the transmission tooth plate 236 maintains stable sliding inside the limiting sleeve 245.

[0040] The transmission sprocket shaft 244 is rotatably connected to the second transmission sprocket 226 via the first transmission chain 242, and the transmission sprocket shaft 244 is rotatably connected to the first transmission sprocket 12 via the second transmission chain 243. Wedge blocks are fixedly connected to the bottom of both ends of the limiting horizontal plate 225, and the upper part of the power-off frame 223 is in contact with the wedge blocks.

[0041] Through the above technical solution, the transmission sprocket shaft 244 can be rotatably connected to the second transmission sprocket 226 through the first transmission chain 242. Therefore, when the drive motor 227 rotates, it can control the transmission sprocket shaft 244 to rotate. Moreover, the transmission sprocket shaft 244 is rotatably connected to the first transmission sprocket 12 through the second transmission chain 243, thereby enabling transmission between the upper and lower sets of transmission sprocket shafts 244 of the transmission part 24, so that the two sets of transmission sprocket shafts 244 keep rotating synchronously and in the same direction. Wedge blocks are fixedly connected to the bottom of both ends of the limiting horizontal plate 225, so that the upper part of the power-off frame 223 abuts against the wedge blocks, thereby making the power-off frame 223 tilted at the bottom of the limiting horizontal plate 225, and facilitating the bottom of the power-off frame 223 to contact the switch on the outer surface of the electrical component 111.

[0042] A transmission gear is fixedly installed inside the limiting sleeve 245 and on the outer surface of the transmission sprocket shaft 244. The transmission gear plate 236 inside the second connecting part 21 and the first connecting part 23 is slidably connected inside the limiting sleeve 245 through the transmission gear.

[0043] Through the above technical solution, a transmission gear can be fixedly installed inside the limiting sleeve 245 and on the outer surface of the transmission sprocket shaft 244. Moreover, the transmission gear plates 236 inside the second connecting part 21 and the first connecting part 23 are slidably connected inside the limiting sleeve 245 through the transmission gear, which facilitates the transmission of the two sets of transmission gear plates 236 inside the limiting sleeve 245 and ensures that the two sets of transmission gear plates 236 slide synchronously in opposite directions.

[0044] The working principle of this invention is as follows: During long-term operation of the communication cabinet, heat, water vapor, and other gaseous substances are easily generated inside the cabinet, leading to the accumulation of high-concentration oxygen. When the oxygen concentration sensor 14 detects that the oxygen concentration has increased to the set value of 21%, the drive motor 227 will be activated. Simultaneously, the drive motor 227 will drive the threaded rod 222 at the bottom to rotate synchronously. The rotation of the threaded rod 222 will cause the second transmission sprocket 226 to rotate synchronously. When the second transmission sprocket 226 rotates, it will drive the transmission sprocket shaft 244 through the first transmission chain 242 on the outer surface. Moreover, the transmission sprocket shaft 244 will drive the transmission rod 16 to rotate synchronously through the second transmission chain 243. At the same time, the transmission rod 16 will... The first transmission sprocket 12 at the bottom drives another set of transmission sprocket shafts 244 to rotate synchronously. Therefore, when the two sets of transmission sprocket shafts 244 in the upper and lower parts of the transmission section 24 rotate synchronously, they will drive the two sets of transmission tooth plates 236 inside the limiting sleeve 245 to slide synchronously in opposite directions. At the same time, the two sets of transmission tooth plates 236 will drive the second connecting part 21 and the first connecting part 23 to slide away from each other until the limiting plate 234 on the side of the second filter plate 235 is engaged with the inner surface of the communication cabinet 112. Moreover, when the protective side plates 232 inside the second connecting part 21 and the first connecting part 23 slide, they will drive the protective top plate 237 at the top to slide inside the insertion slot 110, thereby causing the two sets of protective top plates 237 to separate from each other inside the top of the communication cabinet 112. The connecting part 21 and the first connecting part 23 extend on both sides of the communication cabinet 112, and the two sets of protective top plates 237 are separated from each other. This allows the high concentration of oxygen inside the communication cabinet 112 to diffuse outward through the first filter plate 17 and the second filter plate 235, thereby reducing the oxygen concentration inside the communication cabinet 112 and eliminating potential hazards. Simultaneously, as the drive motor 227 drives the second transmission sprocket 226 to rotate, the threaded rod 222 rotates synchronously. At the same time, the limiting horizontal plate 225, limited by the limiting rod 224, descends on the outer surface of the threaded rod 222. Simultaneously, the limiting horizontal plate 225 drives the bottom power-off frame 223 to descend synchronously, causing the bottom end of the power-off frame 223 to connect with the switch on the outer surface of the electrical component 111. When the power-off frame 223 descends, it presses the switch downwards and flips it over. Furthermore, the power-off frame 223 is limited by the outer surface of the electrical component 111 during its descent, causing it to deflect outwards. After the switch deflects downwards, the power-off frame 223 returns to its original deflection under the elastic force of the tension torsion spring 221, placing the bottom of the power-off frame 223 at the bottom of the switch. Therefore, after the switch deflects and disconnects, the communication cabinet is powered off, preventing the presence of a fire source or electric arc inside the cabinet, which could ignite the high concentration of oxygen inside the cabinet and cause an explosion. Therefore, when the oxygen concentration inside the communication cabinet 112 increases, it is necessary to control the operation to power off the communication cabinet and simultaneously release the oxygen inside.This reduces the oxygen concentration inside the communication cabinet 112, thus providing double protection and enabling the communication cabinet to be explosion-proof. During maintenance, once the oxygen concentration inside the communication cabinet 112 drops to the standard value, the drive motor 227 is reversed, causing the limit plate 225 to rise on the upper surface of the threaded rod 222. Simultaneously, the power-off frame 223 causes the switch on the outer surface of the electrical component 111 to deflect upwards, energizing the communication cabinet. At the same time, the second transmission sprocket 226 drives the first transmission sprocket 12 to rotate synchronously via the first transmission chain 242 and the transmission sprocket shaft 244, thereby controlling the second connecting part 21 and the first connecting part 23 to slide back until the protective side plate 232 engages with the outer surface of the communication cabinet 112. The slot 11 engages, and simultaneously, the protective top plate 237 seals the bottom of the first filter plate 17, thus completing the reset process. The warning light strip 231 stops illuminating, and the power-off frame 223 rises to the upper outer surface of the electrical component 111, thus preparing the communication cabinet for subsequent explosion-proof operations. When the limit plate 234 contacts the inner surface of the communication cabinet 112, it presses the control button, energizing the warning light strip 231. Therefore, the warning light strip 231 emits a warning light, alerting non-professionals not to approach, thus providing a warning and protection effect to passersby. Therefore, installing the explosion-proof mechanism 2 inside the protective mechanism 1 can quickly reduce the oxygen concentration inside the communication cabinet and simultaneously provide power-off protection, preventing an explosion accident.

[0045] The foregoing detailed one embodiment of the present invention, but this is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the present invention should still fall within the patent coverage of the present invention.
