Abstract

The invention relates to the field of down-leading optical cable protection and specifically provides a down-leading optical cable protection device and protection method. The down-leading optical cable protection device comprises a flow guide protector, a sealing connector, and a water seepage structure. The flow guide protector is tubular in structure and sleeves a ground leading-in part of a down-leading optical cable. The sealing connector connects the flow guide protector and the down-leading optical cable hermetically. The water seepage structure is arranged below the leading-in ground of the down-leading optical cable. The down-leading optical cable sleeved with the flow guide protector bends for a section in the water seepage structure and then the end portion is led to the ground and connected to a cable trough at the ground. The lowest end of the flow guide protector bending in the water seepage structure is provided with a drain hole. The device and the method protect down-leading optical cables from multiple aspects such as optical cable blocking and optical cable down-leading, solve the long-term problems of freezing damage and freezing breakage of the down-leading optical cables and improve the optical cable operation reliability.

Description

technical field [0001] The invention relates to the protection field of down-conducting optical cables, and specifically relates to a protection device and a protection method for down-conducting optical cables. Background technique [0002] The optical cable has been running for a long time under natural conditions. After the lead-in cable enters the cable channel through the lead-in steel pipe, due to the poor sealing of the upper end of the lead-in steel pipe and the protective sleeve or the weathering of the sealing material, the sealing effect is lost. Rainwater and ground The accumulated water can enter the bending part of the optical cable through the upper part of the frame and the cable channel, and gradually accumulate in the lower part of the optical cable, resulting in water accumulation in the pipe. In winter, the water accumulated in the steel pipe at the lower part of the cable will freeze, because the ice body expands, causing severe extrusion on the optical ...
