Description
The present invention relates to a kind of screw propeller that is used for and drive ship stern tube leak free fender guard; wherein reserve an intermediate cavity between pipe and the screw propeller wheel hub on the quarter; it by a tubulose with the concentric protective case of screw propeller wheel hub be that so-called cable protector is covered; this protective case one side is fixed on the stern tube, and opposite side jumps to the screw propeller wheel hub and leave a circular clearance.
(DE-AS1120921 in this class fender guard; DE-AS1183399) a kind of fender guard; provided as " cable protection " legend; though a kind of enough protection that are used for the stern tube leak free to cable wire and hawser cable are provided; be that they can not clamp-on narrow relatively circular clearance between protective case and the screw propeller wheel hub; but can not protect quite thin rope-like constructed; this class formation thing is because the current that cause of screw propeller and poured this narrow circular clearance; rotation in protected then cover part is in addition caught and is wound on around the prop shaft; like this, just may cause damaging stern tube leak free end instr owing to twining the formation thing.
In order to eliminate these shortcomings, suggestion had so been arranged, promptly protective case and stern tube do not rigidly fix, and protective case is connected with the screw propeller wheel hub, and it rotates (DE-PS313669) with propeller boss.The protective case of a this as work capstan winch these rope yarn terminations of can reeling certainly, and to stern tube sealing can not cause damage.
Though this known fender guard has been realized its purpose for quite thin rope, also have shortcoming, promptly thick tow and cable wire also can twine, and this just may cause the screw propeller locking and make engine breakdown and analogue thus.
The task that the present invention proposes is; overcome aforesaid shortcoming; and provide a kind of stern tube leak free fender guard that is used for according to this; it makes that on the one hand sealing is harmless to the thin relatively rope-like constructed thing of clamp-oning the circular clearance to stern tube, does not provide the running surface of coiling on the other hand yet to thick rope.
The present invention solves like this to this task: in the intermediate cavity between stern tube in protective case and screw propeller wheel hub; the ring concentric in a U-shaped cross section of configuration with the screw propeller wheel hub; its U-shaped opening radially outward points to; and make it so dispose and determine in this circular clearance relatively; promptly; by the fishing tackle rope that the circular clearance may be clamp-oned, fishing net or similar rope-like constructed thing termination are caught and are enwinded by this ring.
By this measure, carry the task except that solving, also reached other favourable effects, promptly clevis eye spare is because its big relatively capacity, will can be used as the warehouse of a relatively large coiling thing with the time of run that a docking time spent adapts at least usually and works for long relatively.
After ship being introduced dock, this clevis eye will be unstowed at every turn.But for such a case, promptly this clevis eye may twine fullly prematurely entirely, and this fender guard can et out of order yet, thereby stops entering of new twister because by a kind of delay effect on the circular clearance twister is torn.
An enforcement structure by apparatus of the present invention is stipulated like this; during the protective case that promptly has narrow relatively circular clearance between screw propeller wheel hub and protective case is provided with; this clevis eye spare is rigidly fixed on the end face of this screw propeller wheel hub with the leg piece of its screw propeller side; and; another leg piece stretches in the intermediate cavity between stern tube and screw propeller wheel hub, is covered with certain distance and stops (claim 2) apart from protection simultaneously.
Like this, conception plans of the present invention can be simple especially and the little mode of cost realize.
The additional embodiments regulation; for structural details is so to be provided with; promptly; between screw propeller wheel hub and protective case, be equipped with a big relatively circular clearance; according to this; this clevis eye spare moves a corresponding distance (claim 3) to the protective case direction; for this reason; not that an attachment flange (claim 4) that extends radially inwardly is set on clevis eye spare; be exactly that this spacing part is made of a leg piece continuation of stretching this clevis eye stern tube side that reaches protective case and fix there; this moment, another leg piece was done freely to stop to the axial distance of screw propeller wheel hub; and rigidly fix a tubular ring concentric with it on the screw propeller wheel hub, this ring reaches in the leg piece of screw propeller side of clevis eye and the gap between protective case (claim 5).
In the sketch mode fender guard of the present invention has been described for example in the accompanying drawings.
Accompanying drawing 1 is by an embodiment sectional side elevation of claim 2
Accompanying drawing 2 is by the sectional side elevation of an embodiment of claim 4
Accompanying drawing 3 is by the sectional side elevation of an embodiment of claim 5
The stern tube sealing that in accompanying drawing 1, utilizes 1 one of expression to be provided with as the multiple tracks lip seal, its sealing lip 2 and sleeve 3 synergies, these sleeve 3 close-fittings are on prop shaft 4, and end and screw propeller wheel hub 5 be rigidly connected by flange 3a, and the other end is charged in the stern tube 6.
The tube-shaped cover of middle cavity 7 usefulness 8 that forms thus covers, and this protective case one side is rigidly fixed on the stern tube 6, and its other end is cross over screw propeller wheel hub 5 the preceding paragraphs distance and form free circular clearance 9 with the cylindrical platform 11 of cutting that has herein.
In the cavity 7 that forms by protective case 8, settle a U-shaped and the ring 10 concentric with screw propeller wheel hub 5; this hoop is outward also promptly to protective case 8 openings; also the leg piece 10a with its screw propeller side so is rigidly fixed on the end face of wheel hub 5, and promptly the outward flange of described leg piece roughly aligns with the cylindrical platform 11 of cutting of wheel hub 5.Thus, the size of this clevis eye is chosen such that promptly its recess space can hold by the fishing tackle rope, and the termination of fishing net or similar rope-like constructed thing may be squeezed into many coiling occupy-places of circular clearance.
The configuration of a kind of protective case of expression in accompanying drawing 2, wherein, though sealing has accompanying drawing 1 to implement the same case of structure with regard to stern tube, the obvious increase shown in Figure 1 made a farfetched comparison in the circular clearance between screw propeller wheel hub and protective case.
