LIGHTNING CONDUCTOR STRUCTURE IN TELESCOPIC MAST
PROBLEM TO BE SOLVED: To provide a lightning conductor structure that can secure energization irrespective of a telescopic length.SOLUTION: In a marine telescopic hard sail comprising multi-stage hard sails supported by a telescopic mast M and telescopically moving in the vertical direction, unit masts 1-3 of respective stages are configured such that an upper stage side unit mast 2 is held with a slide plate 6 made of a nonconductive material mounted in an inner circumferential wall of a lower stage side unit mast 1, a lightning rod 7 is mounted in the upper end of the telescopic mast M, and a conduction device 10 mounted with a slider in a leaf spring contacted with a conductor is mounted in the outer circumferential surfaces of the unit masts 1-3 of the respective stages. An energizing path is secured by the conductor of the conduction device 10, and thereby the breakage of hydraulic equipment and electronic equipment in the mast due to lightning can be avoided.
【課題】伸縮長さによらず通電確保できる落雷時導通構造を提供する。【解決手段】伸縮マストＭに支持されて上下方向に伸縮する複数段の硬帆からなる船舶用伸縮硬帆において、各段の単位マスト１〜３は、下段側単位マスト１の内周壁に取付けられた非通電材料製のスライドプレート６で上段側単位マスト２が保持されており、伸縮マストＭの上端部には避雷針７が取付けられており、各段の単位マスト１〜３の外周面間において、通電体を接触させる板バネに摺動子を取付けた導通装置１０が取付られている。導通装置１０の通電体により、通電経路を確保することにより、落雷によるマスト内部の油圧機器や電子機器の破損を回避できる。【選択図】図１
