A cable branch box that is conducive to air exchange

Abstract

The invention discloses a cable branch box beneficial to air exchange. The cable branch box comprises a cable branch box main body, exhaust seats are symmetrically arranged at left and right sides ofthe cable branch box main body, a vent pipe is arranged at the center of the top portion of the cable branch box main body, the top portion of the vent pipe is provided with a canopy, operation boxesare symmetrically arranged at left and right sides of the top portion of the cable branch box main body, the bottom portions of the front side walls of the two sets of the operation boxes and the front side wall of the vent pipe are provided with operation doors, the inner cavity of the vent pipe is provided with a separation baffle, the bottom portion of the separation baffle is provided with a flow guide pipe, the flow guide pipe is provided with a solenoid valve, the inner cavities of the operation boxes are provided with rotation handles, the bottom portions of the rotation handles are provided with transmission rods, and a thread bushing sleeves the outer wall of the connection position between the transmission rods and the cable branch box main body. The cable branch box is reasonable in structural design, can accelerate the heat exchange efficiency between the cable branch box main body and the outside when heat dissipation is needed, can play a role in preserving heat in the cable branch box main body in cold weather, can switch between heat preservation and heat dissipation, and better meets the actual use requirements.

Description

technical field [0001] The invention relates to the technical field of cable branch boxes, in particular to a cable branch box that is beneficial to air exchange. Background technique [0002] With the development of the cabling process of the distribution network, when the independent loads with small capacity are concentrated, the cable branch box can be used to connect multiple branches of the cable, because the branch box cannot directly operate each channel, and the cable branch box is widely used. For outdoor use, with the advancement of technology, the number of cable branch boxes with switches is also increasing, and urban cables often use dual-circuit power supply mode, so some people directly call the branch boxes with switches as outdoor ring network cabinets, but at present Most of such ring network cabinets cannot realize distribution automation, but manufacturers have launched outdoor ring network cabinets that can automate distribution networks, which also blu...

Problems solved by technology

[0002] With the development of the distribution network cable process, when the distribution of independent loads with small capacity is relatively concentrated, the cable branch box can be used to connect multiple branches of the cable, because the branch box cannot directly operate each channel, and the cable branch box is widely used. For outdoor use, with the advancement of technology, the number of cable branch boxes with switches is also increasing, and urban cables often use double-circuit power supply, so some people directly call the branch boxes with switches as outdoor ring network cabinets, but at present Most of such ring network cabinets cannot realize distribution network automation, but manufacturers have launched outdoor ring network cabinets that can distribute network automation, which also makes the boundaries between cable branch boxes and ring network cabinets begin to blur

[0003] At present, the cable branch box generally adopts a closed structure. Heat is easily generated inside the transmission current, which is easy to accelerate the aging of the cable, or cause accidents. The electric-driven ventilation structure will also generate heat when it works for a long time. The most important thing is that the ventilation The ventilation structure only has the function of one-way ventilation, the ventilation efficiency is low, and the air exchange effect is poor. Since the cable branch boxes are mostly used outdoors, in the cold weather in the northern winter, the heat exchange rate between the internal heat of the cable branch box and the external heat is too fast , the cold environment will affect the cable, and it is easy to accelerate the aging of the cable. Therefore, we propose a cable branch box that is conducive to air exchange
