Description
【考案の詳細な説明】 （産業上の利用分野） この考案は、昇降式スラスタの構造に関するもので、とくに昇降式スラスタの 封水筒のために設けられるシール部の周辺の構造に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a structure of a lifting thruster, and more particularly to a structure around a seal portion provided for a water cylinder of a lifting thruster.
（従来の技術） 第３図は従来の昇降式スラスタの構造を示し、モータ１の動力を入力軸２、ベ ベルギヤ３、およびプロペラ軸４を介してプロペラ５に伝え、スラストを発生さ せる構造をそなえる。船体外と船体内とはシール６によって分離されている。ス ラスタを使用しないときは、一対の油圧シリンダ７，７によって上方に引き上げ られ、船体外部に設けた部屋８内に収容格納される。(Prior Art) FIG. 3 shows the structure of a conventional lift type thruster, in which the power of the motor 1 is transmitted to the propeller 5 via the input shaft 2, the bevel gear 3 and the propeller shaft 4 to generate thrust. Provide. The outside of the hull and the inside of the hull are separated by a seal 6. When the thruster is not used, it is pulled up by a pair of hydraulic cylinders 7, 7 and housed and stored in a room 8 provided outside the hull.
（考案が解決しようとする課題） 一般に、シール６は損傷するケースが非常に多いが、その理由の一つとして、 部屋８の中は殆ど水流がなく、そのため、ふじつぼ、かきなどの介殻類が封水筒 ９の表面に付着し易く、これらの介殻が付着した状態のまゝで封水筒９が昇降し 、そのつどシール６の内面を擦過することになるということが挙げられる。シー ル６が擦過損傷すると、船外からの水の侵入を防ぐための手段がほかに装備され ていないので、そのつど船をドックに入れて修理する必要があり、出費が嵩むと いう問題点があった。(Problems to be solved by the invention) In general, there are many cases where the seal 6 is damaged, and one of the reasons is that there is almost no water flow in the room 8 and therefore shells such as barnacles and oysters. Can easily adhere to the surface of the water sealing cylinder 9, and the water sealing cylinder 9 moves up and down until the shells are adhered, and the inner surface of the seal 6 is rubbed each time. If the seal 6 is scratched and damaged, there is no other means to prevent the intrusion of water from the outside of the ship, so it is necessary to put the ship in the dock and repair it each time, which is expensive. was there.
この考案は、上記の問題点を解決するためになされたもので、封水筒のために 設けられるシールの摺動面の損傷を著しく軽減し、シールからの水の侵入を防止 することによって、シールの修理のための入渠の頻度を減少し、もって維持費の 軽減を達成しうる昇降式スラスタの構造を提供することを目的としている。 The present invention has been made to solve the above problems, and significantly reduces damage to the sliding surface of the seal provided for the water sealing cylinder, and prevents water from entering through the seal. It is an object of the present invention to provide a structure of an elevating thruster which can reduce the frequency of the dock for repairing the building and thus reduce the maintenance cost.
（課題を解決するための手段） 上記の目的達成のために、本考案の昇降式スラスタは、昇降装置によってプロ ペラ部を上方に移動して格納できる昇降式スラスタにおいて、船体内外を貫通し て昇降する封水筒の外周面に対向して設置されて常時船外の水をシールするシー ルのほかに、そのシールよりもさらに船外の水に近い側であって封水筒の外周面 との間にごく僅かの隙間を残す関係位置に、封水筒の上下移動に応じて封水筒周 面の付着物を掻き落とすための刃物が船体側から突設された構造をそなえている 。(Means for Solving the Problems) In order to achieve the above object, the lifting thruster according to the present invention is a lifting thruster that can move a propeller part upward by a lifting device and store it. In addition to the seal that is installed facing the outer peripheral surface of the rising and lowering water sealing cylinder and constantly seals the water outside the ship, it is closer to the water outside the ship than the seal and the outer peripheral surface of the water sealing cylinder. It has a structure in which a blade for scraping off the deposits on the surface of the water sealing cylinder is projected from the hull side in accordance with the vertical movement of the water sealing cylinder at a position where a very small gap is left between them.
（作用） 封水筒の付着物を掻き落とすための刃物が、封水筒の船体貫通部に設けられる シールよりもさらに船外の水に近い側に、封水筒の外周面に対向してごく僅かの 隙間を残す関係位置に設けられているので、封水筒が上下移動するとき、封水筒 の付着物は、必ず上記シールに到達する以前に刃物の部分を通過して刃物によっ て該付着物が掻き落とされ、封水筒周面が常に平滑に保たれるので、該周面と摺 動するシール内面の摩耗損傷が著しく軽減される。(Function) The blade for scraping off the deposits on the water sealing cylinder is located on the side closer to the water outside the ship than the seal provided in the hull penetrating part of the water sealing cylinder, facing the outer peripheral surface of the water sealing cylinder. Since it is provided at a related position that leaves a gap, when the water sealing cylinder moves up and down, the adhered matter on the water sealing cylinder must pass through the blade part before it reaches the seal, and the adhered material should be attached by the blade. Since the peripheral surface of the water sealing cylinder is always scraped off and kept smooth, wear damage on the inner surface of the seal that slides on the peripheral surface is significantly reduced.
（実施例） つぎにこの考案の実施例について、図面に基づいて詳細に説明する。(Example) Next, the Example of this invention is described in detail based on drawing.
第１図および第２図において、第３図に用いた符号と同一の符号は、同図にお けると同等の部材を表示するものとする。１０は封水筒で、本図例では、プロペ ラ部と一体に連結された旋回筒１１と封水筒１０とは別体に構成されている。１ ２は旋回筒１１のためのシールで、封水筒１０と旋回筒１１との間に介在する。 In FIGS. 1 and 2, the same reference numerals as those used in FIG. 3 indicate the same members as those in FIG. Reference numeral 10 denotes a water sealing cylinder. In this example, the swirling cylinder 11 integrally connected to the propeller portion and the water sealing cylinder 10 are configured separately. Reference numeral 12 denotes a seal for the swirl cylinder 11, which is interposed between the water sealing cylinder 10 and the swirl cylinder 11.
１３は封水筒１０のためのシールで、船体Ａと封水筒１０との間に介在する。Reference numeral 13 denotes a seal for the water sealing cylinder 10, which is interposed between the hull A and the water sealing cylinder 10.
１４は予備シールで、シール１３よりも船外の水に近い側に設けられている。 Reference numeral 14 denotes a preliminary seal, which is provided closer to the water outside the ship than the seal 13.
予備シール１４は、第２図に示すように、中空の弾性材によってリング状に構成 され、出入口１４ａから中空部１４ｂに向かって空気圧ライン１５の空気圧を導 通することにより、予備シール１４が内側に向かって膨張して、突起１４ｃが封 水筒１０の外周面に隙間のない状態に押し付けられて完全なシール状態を実現す る。空気圧を遮断すると、予備シール１４はその弾性によって旧状に復帰し、封 水筒１０との接触が開放されて両者の間に再び隙間が生じる。As shown in FIG. 2, the preliminary seal 14 is made of a hollow elastic material in a ring shape and conducts the air pressure of the pneumatic line 15 from the inlet / outlet port 14a to the hollow portion 14b, so that the preliminary seal 14 is not inward. The projection 14c expands toward and is pressed against the outer peripheral surface of the water sealing cylinder 10 in a state where there is no gap, thereby realizing a completely sealed state. When the air pressure is cut off, the pre-seal 14 returns to the old state due to its elasticity, the contact with the water sealing cylinder 10 is released, and a gap is formed again between the two.
１６は、空気圧ライン１５の途中に設けられた開閉弁であり、１７はシール１ ３のパッキン部に設けられた圧力センサーである。本実施例のものは、開閉弁１ ６と圧力センサー１７とが電気的に連結されており、圧力センサー１７の検出値 に応じて開閉弁１６の開閉が制御されるように構成されている。 Reference numeral 16 is an on-off valve provided in the middle of the pneumatic line 15, and 17 is a pressure sensor provided in the packing portion of the seal 13. In this embodiment, the on-off valve 16 and the pressure sensor 17 are electrically connected to each other, and the opening / closing of the on-off valve 16 is controlled according to the detection value of the pressure sensor 17.
１８は刃物で、シール部の最も船外の水に近い側に封水筒１０の外周面との間 にごく僅かの隙間を残して設けられている。刃物１８は、封水筒１０が昇降する とき、封水筒１０の周面に付着する介殻やゴミなどを掻き落とすためのもので、 この予防的措置によって、シール１３ないしは予備シール１４の内面の損傷が著 しく軽減される。１９は昇降ガイドで、封水筒１０と一体的に昇降して円滑な昇 降動作を誘導するためのものである。２０は旋回モータで、旋回筒１１を封水筒 １０の内部で旋回せしめ、プロペラ５の推力の方向を自由に変換せしめるための ものである。 Reference numeral 18 denotes a blade, which is provided on the side of the seal portion closest to the water outside the ship, leaving a very small gap between the outer peripheral surface of the water sealing cylinder 10. The blade 18 is for scraping off shells, dust, and the like adhering to the peripheral surface of the water sealing cylinder 10 when the water sealing cylinder 10 moves up and down. This preventive measure prevents damage to the inner surface of the seal 13 or the preliminary seal 14. Significantly reduced. Reference numeral 19 is an elevating guide for elevating and lowering integrally with the water sealing cylinder 10 to guide a smooth ascending / descending operation. Reference numeral 20 is a turning motor for turning the turning tube 11 inside the water sealing tube 10 and freely changing the direction of the thrust of the propeller 5.
つぎに、このように構成された昇降式スラスタの使用態様について説明する。 Next, a usage mode of the lift type thruster thus configured will be described.
原則として、予備シール１４にシール作用を持たせるのは、封水筒１０が昇降動 作を必要としないときに限るものとし、封水筒１０が昇降動作を行うときのシー ル機能は、従来からのシール１３によって分担せしめるものとして、このときは 予備シール１４は封水筒の周面との間に隙間のある状態に放置するものとする。As a general rule, the pre-seal 14 should have a sealing function only when the water sealing cylinder 10 does not need to move up and down, and the sealing function when the water sealing cylinder 10 moves up and down is the same as in the conventional case. At this time, the spare seal 14 is allowed to be shared by the seal 13, and the spare seal 14 is left in a state where there is a gap between it and the peripheral surface of the water sealing cylinder.
このような使用状態において、封水筒１０がシール部を貫通して昇降すると、 損傷の対象となるのは主にシール１３であって、予備シール１４の損傷は、シー ル１３のものと比較してさらに軽微である。いま、封水筒１０が周面に介殻やゴ ミなどを帯同して上方に移動しようとすると、最も船外の水に近い側に封水筒１ ０の外周面との間にごく僅かの隙間を残して設けられた刃物１８によって、周面 の異物は強制的に掻き取られる。この予防的措置によって、シール１３の内面の 摩耗はその発生が格段に小さく抑えられる。 In such a usage state, when the water sealing cylinder 10 penetrates the seal portion and goes up and down, the seal 13 is mainly the target of damage, and the damage of the preliminary seal 14 is larger than that of the seal 13. It is even lighter. Now, when the water sealing cylinder 10 tries to move upward along with the shells and trash on the peripheral surface, a very small gap is created between the outer peripheral surface of the water sealing cylinder 10 on the side closest to the water on the outboard. The foreign matter on the peripheral surface is forcibly scraped off by the blade 18 provided left. By this preventive measure, the occurrence of wear on the inner surface of the seal 13 is significantly suppressed.
なお、実施例として第１図および第２図に示すものは、このようにして極力そ の発生が抑えられたシール１３の摩耗損傷が、次第に累加したときの対応手段を も、その構成中に含むものである。その対応手段の使用の態様について、つぎに 説明する。 The embodiment shown in FIGS. 1 and 2 also includes a means for responding to progressive wear of the seal 13 whose generation is minimized in this way. It includes. A mode of using the corresponding means will be described below.
シール１３が次第に損耗してシール機能が劣化してくると、シール１３のパッ キン部に水圧が発生するに至る。このとき、圧力センサー１７が該水圧を検出し 、開閉弁１６に対して空気圧の導通を指令し、該空気圧が予備シール１４に導通 されて予備シール１４によるシール状態が全く自動的に行われる。この結果、シ ール１３の内部のパッキン取替作業が船内側から自由に行われ得る状態となるの で、シールの修理作業のために船を入渠させるなどの必要はない。 When the seal 13 gradually wears and the sealing function deteriorates, water pressure is generated in the packing portion of the seal 13. At this time, the pressure sensor 17 detects the water pressure, commands the on-off valve 16 to conduct air pressure, and the air pressure is conducted to the preliminary seal 14, whereby the sealing state by the preliminary seal 14 is performed completely automatically. As a result, the packing replacement work inside the seal 13 can be freely performed from the inside of the ship, so that there is no need to dock the ship for repair work of the seal.
また、開閉弁１６の開閉操作を、圧力センサー１７からの指令系統とは別に、 これに加えて操縦スタンドからの指令によって制御し得るように設定すると、船 の運航状態に応じて、プロペラ部の昇降動作のときにのみ予備シール１４を開放 して隙間のある状態とし、昇降動作を伴わない運航状態のときは、予備シール１ ４による完全シールの状態とする二段シール装置としての使用態様の実現も可能 である。 Further, if the opening / closing operation of the on-off valve 16 is set to be controllable by a command from the control stand in addition to the command system from the pressure sensor 17, the propeller section of the propeller part can be operated according to the operating condition of the ship. The preliminary seal 14 is opened only during the raising / lowering operation so that there is a gap, and when the operating state is not accompanied by the raising / lowering operation, the preliminary seal 14 is the complete seal state. Realization is possible.
（考案の効果） この考案にかかる昇降式スラスタの構造によれば、封水筒の付着物を掻き落と すための刃物が、封水筒の船体貫通部に設けられるシールよりもさらに船外の水 に近い側に、封水筒の外周面に対向してごく僅かの隙間を残す関係位置に設けら れているので、封水筒が上下移動するとき、封水筒の付着物は、必ず上記シール に到達する以前に刃物の部分を通過して、刃物によって該付着物が掻き落とされ る。その結果、封水筒周面が常に平滑に保たれるので、該周面と摺動するシール 内面の摩耗損傷の度合いが著しく軽減され、シールの修理交換のための入渠の頻 度が減少し、維持費の軽減が達成できるなどのすぐれた効果がある。(Effect of the device) According to the structure of the lifting thruster according to the present invention, the blade for scraping off the adhering material on the water sealing cylinder is exposed to the water outside the ship more than the seal provided on the hull penetration part of the water sealing cylinder. Since it is provided on the near side so as to face the outer peripheral surface of the water sealing tube and leave a very small gap, when the water sealing tube moves up and down, the deposits on the water sealing tube must reach the above seal. The adhering material is scraped off by the blade, which has previously passed through the portion of the blade. As a result, since the peripheral surface of the water sealing cylinder is always kept smooth, the degree of wear and damage on the inner surface of the seal that slides with the peripheral surface is significantly reduced, and the frequency of docking for repair and replacement of the seal is reduced. It has excellent effects such as reduction of maintenance cost.
