Optical cable transfer box

Abstract

The invention discloses an optical cable transfer box, and belongs to the technical field of communication equipment. A sand falling mechanism is arranged in the upper part inside a box body. The sand falling mechanism comprises a partition plate, and a spatial area above the partition plate is filled with fine sands. Two symmetrical rotatable baffle plates are arranged at the lower side of the partition plate, and an electronic inductive switch is arranged at the front end of each baffle plate. A pneumatic cylinder is arranged in a wiring bin. A power output shaft of a stepping motor is connected with an air nozzle. The pneumatic cylinder is connected with an air pump. The air nozzle is sleeved with a thermal infrared sensing device. Compared with the prior art, by arranging the unique air jetting device and the sand falling mechanism in the optical cable transfer box, a fire occurring in the box body is extinguished first by high-pressure gas and then by the fine sands, the phenomenon of short circuit of an optical fiber line caused by fire extinguishing by water is avoided, the fire extinguishing effect is good, and the purpose of controlling fire and protecting equipment in the box body is achieved.

AI Technical Summary

Problems solved by technology

[0003] The current optical cable transfer box is mainly used for outdoor projects. Since the optical cable transfer box has an optical module card that will separate multiple optical fiber signal lines from the optical fiber circuit board to the optical fiber center backbone switch, there is heat during the transmission of optical fiber signals. And the optical cable transfer box is a relatively airtight box, the accumulation of heat will cause the temperature inside the box to rise, especially in the hot summer, the continuous high temperature will make the temperature inside the box very high, and then cause a fire, which will definitely damage the The transmission engineering of optical fiber signal causes serious consequences
