Air supplementing device and optical cable installation device

Abstract

The invention discloses an optical cable installation system and an air supplementing device. The air supplementing device is used for supplementing air into a pipeline provided with an optical cable and comprises a first air supplementing housing; a second air supplementing housing which is combined with the first air supplementing housing in an openable mode so as to limit an enclosed high-voltage air supplementing cavity during combination, wherein the air supplementing cavity is constructed to be used for accommodating a part of the pipeline with an air inlet arranged in the pipe wall of the pipeline so as to convey air into the pipeline; and a first air inlet apparatus which is arranged on the first air supplementing housing or the second air supplementing housing so as to supply high-voltage air into the air supplementing cavity. By using the air supplementing device and the optical cable installation system, when the optical cable is laid over a long distance, the air can be supplemented into the optical cable through selecting different positions of the optical cable, and the optical cable can keep advancing forwards high efficiently.

Description

technical field [0001] The invention relates to an optical cable installation system, in particular to an air supply device and an optical cable installation system for installing an optical cable in a pipeline by means of air blowing. Background technique [0002] The known method of installing optical cables into ducts by air blowing. This method can reduce the resistance of the cable when installing the cable, and can continuously install the cable into a pipe with a length of several hundred to several kilometers. [0003] figure 1 It is a schematic diagram showing the principle of an optical cable installation device in the prior art. The optical cable installation device comprises a duct 203 for installing an optical cable 300, an air blowing device 201 for blowing air into the duct 203, and a double roller 2207 for extruding the optical cable, such as from an optical cable reel, and transporting the optical cable. . Further, an air inlet 205 communicating with an ...
