Description
Technical Field
[0001] The utility model relates to the field of optical cable junction boxes, in particular to an outdoor optical cable junction box. Background Art
[0002] An optical cable junction box, also commonly known as a street cabinet, is typically placed on a trunk optical cable and used for cable branching. It's a passive device, similar in function to a conventional copper cable junction box, except that most optical cables are routed through the junction box and then divided into several smaller pairs of optical cables in different directions. While this function can also be achieved with a fiber optic splice box, the difference is that the junction box allows for patching of optical cables and can also be used for testing and maintenance. Generally, an optical cable junction box is the demarcation point between feeder cables and distribution cables. An optical splitter, in layman's terms, is used to broadcast a light beam from a single fiber core to multiple cores via a physical channel. This is intended to improve the utilization efficiency of the trunk optical fiber and reduce the number of pairs of trunk optical fibers.

Through the technical solution of the present utility model, solar energy resources can be utilized to the greatest extent by using solar panels provided with light tracers, which effectively reduces certain resource waste and unnecessary losses, and maintains the normal operation of communications.
[0004] Most of the existing optical cable junction boxes are not equipped with heat dissipation mechanisms. After the components inside the optical cable junction box are installed, a large number of components work at the same time, which will cause the temperature inside the optical cable junction box to be high. The high temperature can easily damage the components inside the optical cable junction box, causing safety hazards. Therefore, the market urgently needs to develop an outdoor optical cable junction box to help people solve the existing problems. Utility Model Content

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0023] See also Figure 1-4The utility model provides an embodiment: an outdoor optical cable junction box, comprising an optical cable junction box 1, a junction warehouse 101 and an expansion warehouse 102 are respectively provided on both sides of the middle part of the interior of the optical cable junction box 1, and an air suction pipe 2 is fixedly provided on one side of the middle part of the lower end surface of the interior of the junction warehouse 101 and the expansion warehouse 102, the lower end of the optical cable junction box 1 is fixedly connected to a heat exchange box body 3, a plurality of heat dissipation fins 301 are fixedly provided at equal intervals on both sides of the interior of the heat exchange box body 3, a circulation pipe 302 is fixedly connected between the middle parts of the plurality of heat dissipation fins 301 on both sides, and a refrigeration device 303 is fixedly connected to the rear end of the heat exchange box body 3.
[0024] Furthermore, a strip-shaped return air outlet 103 is provided on one side of the lower end surface of the transfer bin 101 and the expansion bin 102, and the lower end of the suction pipe 2 extends to the interior of the heat exchange box 3, so that the internal gas of the heat exchange box 3 can enter the transfer bin 101 and the expansion bin 102 through the two suction pipes 2 respectively.
[0025] Furthermore, a cross bracket 201 is fixedly connected to the upper end of the suction pipe 2, and a suction fan 202 is fixedly connected to the lower end of the cross bracket 201. When the suction fan 202 rotates, the internal gas of the heat exchange box 3 is transported to the transfer bin 101 and the expansion bin 102 respectively through the suction pipe 2.
[0026] Furthermore, both upper and lower ends of the circulation pipe 302 extend out of the rear end surface of the heat exchange box 3 and are fixedly connected to the refrigeration device 303. An openable door 304 is provided at the front end of the heat exchange box 3. The refrigeration device 303 is used for cooling, and the refrigerant is transported to the heat dissipation fins 301 through the circulation pipe 302, so that the heat dissipation fins 301 cool the air inside the heat exchange box 3. When the suction fan 202 transports the cold air inside the heat exchange box 3 to the inside of the transfer bin 101 and the expansion bin 102 respectively, the inside of the transfer bin 101 and the expansion bin 102 are cooled simultaneously. The air pressure inside the transfer bin 101 and the expansion bin 102 increases, so that the hot air inside the transfer bin 101 and the expansion bin 102 flows back to the interior of the heat exchange box 3 through the strip return air port 103 under the action of air pressure and passes through multiple heat dissipation fins 301 for further cooling, so that the air inside the heat exchange box 3 and the transfer bin 101 and the expansion bin 102 flow, thereby realizing internal cooling of the entire optical cable transfer box 1, and effectively avoiding the problem that the use of internal and external air circulation in the optical cable transfer box 1 will cause dust to enter the interior of the optical cable transfer box 1, causing dust to pollute the interior of the optical cable transfer box 1.
[0027] Furthermore, the lower end of the heat exchange box 3 is fixedly connected to a concrete foundation 4 , and the front and rear ends of both sides of the middle of the upper end surface of the concrete foundation 4 are fixedly connected to embedded threaded columns 401 .
[0028] Furthermore, the heat exchange box 3 and the concrete foundation 4 are fixed by four pre-buried threaded columns 401 whose upper ends pass through the lower end surface of the heat exchange box 3 and extend to the inner threaded connection bolts 402 of the heat exchange box 3 .
[0029] Furthermore, a rectangular pad 403 is provided between the lower end of the bolt 402 and the lower end surface of the interior of the heat exchange box 3. The rectangular pad 403 expands the effective area between the bolt 402 and the lower end surface of the interior of the heat exchange box 3, thereby improving the stability of the fixed connection between the heat exchange box 3 and the concrete foundation 4. At the same time, the four bolts 402 are all arranged inside the heat exchange box 3. When the openable compartment door 304 is closed, the optical cable junction box 1 cannot be disassembled from the outside, thereby preventing unauthorized personnel from illegally disassembling the optical cable junction box 1.
[0030] Working principle: When in use, the refrigeration device 303 inside the heat exchange box 3 works, and the refrigerant generated by the refrigeration device 303 flows through the circulation pipe 302 and passes through the heat dissipation fins 301, thereby reducing the air temperature inside the heat exchange box 3. When the suction fan 202 is started, it uses suction to send the cooled air into the transfer bin 101 and the expansion bin 102 through the suction pipe 2, effectively reducing the temperature inside these two areas. With the injection of cold air, the air pressure inside the transfer bin 101 and the expansion bin 102 increases, forcing the hot air to flow back to the inside of the heat exchange box 3 through the strip return air port 103. These refluxed hot air passes through the heat dissipation fins 301 again for cooling, forming a closed-loop air circulation system. This design not only effectively prevents dust from entering the interior of the optical cable junction box 1, but also ensures that the internal components of the optical cable junction box 1 can operate stably at a lower temperature, thereby improving the safety and reliability of the equipment. At the same time, the heat exchange box body 3 is fixedly connected to the concrete foundation 4 through the embedded threaded column 401 and the bolt 402, and a rectangular pad 403 is added to the lower end of the bolt 402 to enhance the stability of the connection and prevent unauthorized disassembly of the optical cable junction box 1 by unauthorized personnel.
