Abstract
Description
Met bovenstaande overwegingen is als NIEUWHEIDSGEDACHTE een hiervoor toepasbare scheepsaandrijvingsmachineinstallatie ontworpen, in het bijzonder bij een voor. deze vaarwegen zo goed mogelijk gevormd scheeps-type n.l. met een zo vlak mogelijke bodem.With the foregoing considerations, as a NEWTHEME THOUGHT, a suitable marine propulsion machine installation has been designed, in particular at a furrow. these waterways as well as possible shaped ship type n.l. with as flat a bottom as possible.
Als aandrijvingsmachine van een overigens normale zeescheepspropeller-vorm 1 is een elektromotor, tegenwoordig bij voorkeur een 3 phasen kort-sluitmotor type, 2 gemonteerd op een gemeenschappelijke aandrijfas 3 in de elektromotor ruimte 4 waarvan de rotor 5 bij voorkeur in lucht roteert en tussen de scheepspropelIer die in water roteert is een kompar-timent met een bekende vorm van mechanische as afdichtingen. 6.As a drive machine of an otherwise normal sea-going propeller form 1, an electric motor, nowadays preferably a 3-phase short-circuit motor type, 2 is mounted on a common drive shaft 3 in the electric motor space 4, the rotor 5 of which preferably rotates in air and between the ship's propeller. rotating in water is a compartment with a known form of mechanical shaft seals. 6.
Zie figuur 1.See figure 1.
De ruimte t.b.v. de elektromotor zal worden voorzien van 2 of meer afzonderlijke motoren, die dan elk apart na elkaar kunnen worden gestart. Dit om het startvermogen van de elektrische stroom leverende scheeps-generator te beperken.The space for the electric motor will be equipped with 2 or more separate motors, which can then be started separately one after the other. This is to limit the starting power of the electric power supplying ship generator.
Aangezien een iets langere vorm van het aandrijvingsmechanisme vloei-stofstromingstechnisch geen enkel bezwaar oplevert, doch daarentegen een grotere diameter van het motorkompartiment wel bezwaarlijk is, kan worden gesteld, dat b.v. 3 afzonderlijke motoren op één as en de garantie van directe waterkoeling zonder enige bijzondere voorziening een relatief groot vermogen brengt bij een zeer beperkte startstroom.Since a slightly longer form of the drive mechanism does not pose any objections in terms of liquid flow, but a larger diameter of the motor compartment is objectionable, it can be stated that e.g. 3 separate motors on one shaft and the guarantee of direct water cooling without any special provision brings relatively high power with a very limited starting current.
De plaatsing van de elektromotor-propeller groep 7 - geheel waterdicht -is uiteraard in het onderste gedeelte van de scheepsvorm. Zie figuur 2.The placement of the electric motor-propeller group 7 - completely waterproof - is of course in the lower part of the ship shape. See figure 2.
Er is geen beletsel om dit midscheeps ofwel aan de achterzijde te projecteren. Eveneens kunnen per schip meerdere van deze groepen worden toegepast.There is no impediment to project this amidships either at the rear. Several of these groups can also be used per ship.
Deze motorgroepen worden "gehangen" aan b.v. doosvormige waterdichte kokers 8 met vaste bodem en voorzien van waterdichte kabeldoorvoeringen 9 t.b.v. de elektrische stroomtoevoer.These motor groups are "hung" on e.g. box-shaped watertight sleeves 8 with a fixed bottom and fitted with watertight cable penetrations 9 for the electric power supply.
Deze waterdichte kokers zijn vertikaal beweegbaar en zijn omsloten door eveneens waterdichte kokers 10 van iets grotere lengte en breedte afmetingen. Deze kokers maken een vast deel uit van de scheepskonstruktie.These watertight tubes can be moved vertically and are enclosed by likewise watertight tubes 10 of slightly longer length and width dimensions. These tubes are a permanent part of the ship's construction.
Zie figuur 3.See figure 3.
De koker 8 kan zodanig hoger of lager worden gesteld, dat bij vrije vaart in ruim water een volledig effect van de aandrijvingsmachine bereikt wordt bij een geheel vlakke scheepsbodem.The sleeve 8 can be set higher or lower in such a way that a full effect of the propulsion machine is achieved with a completely flat ship bottom when sailing freely in ample water.
Intrekbare scheepspropelIer aandrijving door elektromotor(en)Retractable marine propeller powered by electric motor (s)
Het mag als bekend worden verondersteld, dat er vele toepassingen als zodanig bestaan in velerlei variaties. De elektromotor als hulpaandrijvingsmechanisme komt zelfs veelvuldig voor. Ook als separaat in bedrijf te nemen soort buitenboordmotor voor z.g. langzame vaart met electrische aandrijvingsmachines is een bekend verschijnsel .It may be presumed known that there are many applications as such in many variations. The electric motor as an auxiliary drive mechanism is even common. A known phenomenon is also a type of outboard motor for so-called slow travel with electric drive machines which can be put into operation separately.
Al deze toepassingen zijn meestal bij zeeschepen gericht op de vaart in de havens, in het bijzonder in vaargebieden zonder veel hinder van watervervuiling zoals b.v. sterk ontwikkelde plantengroei en/of sterk wisselende of onbekende ondiepten.All these applications are usually aimed at seagoing vessels in ports, especially in sailing areas without much hindrance from water pollution such as e.g. strongly developed plant growth and / or strongly varying or unknown shallows.
Derhalve wordt sinds mensenheugenis de scheepslading in zeehavens gelost of geladen. Ofwel, bij het ontbreken van enige havenfaciliteiten, in open zee.Therefore, the cargo has been unloaded or loaded in seaports since time immemorial. In other words, in the absence of any port facilities, in the open sea.
Vooral grotere zeegaande schepen wagen zich niet graag in riviermondingen met alle verrassingen van onbekende ondiepten en/of vrijwel ondoordringbare waterplantenmassa's. Immers de situering van de voortstuwingspropeller is om redenen van efficiency vrijelijk toegankelijk voor water + eventuele ongerechtigheden.Larger seagoing ships in particular do not like to venture into estuaries with all the surprises of unknown shallows and / or virtually impenetrable water plant masses. After all, the location of the propulsion propeller is freely accessible to water + any iniquities for reasons of efficiency.
Voor min of meer kleinere vaartuigafmetingen (niet zeeschepen), bestemd om te worden gebruikt in genoemd soort moeilijk en riskant te bevaren gebieden is o.m. een waterstraal aandrijvingsmechanisme toepasbaar. Het effectief rendement is duidelijk minder want behalve plaatsverlies aan scheepsruimte t.b.v. de noodzakelijke pompinstalla-tie met adequate leidingen voor aan- en afvoer van het water heeft een dergelijke pompinstallatie een geringer rendement en dus een aanzienlijk grotere aandrijvingsmachine nodig.For more or less smaller vessel dimensions (not sea-going vessels), intended for use in areas of this type that are difficult and risky to navigate, a water jet propulsion mechanism is applicable. The effective efficiency is clearly less, because in addition to loss of space in ship space for the necessary pump installation with adequate pipes for supply and discharge of the water, such a pump installation requires a lower efficiency and thus a considerably larger drive machine.
Nog minder kwetsbaar voor waterplantenmassa's in moerasgebieden en ondiepten is een luchtpropeller aandrijving boven op het vaartuig, doch dit is duidelijk te kostbaar voor normale vracht- en/of enig beduidend passagiersvervoer vanuit enige riviermonding via open zee tot ver in een andere riviermonding.Even less vulnerable to aquatic plant masses in wetlands and shallows is an air propeller drive on top of the vessel, but this is clearly too costly for normal freight and / or any significant passenger transportation from any estuary through the open sea far into another estuary.
In gebieden met dit soort water vervui 1 ingsproblematiek, al dan niet gekombineerd met vele ondiepten, is zeker behoefte aan een redelijk snelle scheepvaart via open zee.In areas with this type of water pollution problem, whether or not combined with many shallows, there is certainly a need for reasonably fast shipping by open sea.
Vooral in subtropische en tropische landen is een snel scheepvaart verkeer wenselijk die zonder overladingsvertragingen (en risico's) ongeveer van huis tot huis passagiers en vracht over zee kan vervoeren.Particularly in subtropical and tropical countries, fast shipping traffic is desirable, which can transport passengers and freight by sea without overload delays (and risks).
Zowel voor als achter de koker 10 zijn met water gevulde komparti-menten 11 en 12, eveneens deel uitmakend van het schip. Bij het varen in zeer ondiepe wateren wordt koker 8 hoger gesteld en de afsluitplaten, 13 en 14, scharnierbaar beweeglijk, in de juiste stromingsposi-tie gesteld. Zie figuur 4.Both in front of and behind the sleeve 10 are water-filled compartments 11 and 12, also part of the ship. When sailing in very shallow waters, tube 8 is raised and the closing plates, 13 and 14, pivotally movable, are set in the correct flow position. See figure 4.
Bij vaarten in twijfel achtig vervuilde wateren, kan volgens figuur 5 de aandrijvingsmachine de gebruikelijke stand behouden middels koker 8. Hierbij blijven de afsluitplaten 13 en 14 vlak op de scheepsbodem gesloten en wordt de zeefinrichting 15 scharnierend tot onder het laagste deel van de aandrijvingsmachine in schuine stand gehouden.When sailing in doubt-like polluted waters, according to figure 5 the propulsion machine can maintain the usual position by means of tube 8. The closing plates 13 and 14 remain closed flat on the bottom of the ship and the sieving device 15 is hinged to below the lowest part of the propulsion machine. held.
De scharnierende zeef heeft bij voorkeur geen dwarsverbindingen tussen de stangen, uitgezonderd bij het scharnierpunt.The hinged screen preferably has no cross connections between the rods, except at the hinge point.
Bij het varen in door plantengroei vervuild water kan volgens figuur 6 de koker 8 hoger worden gesteld, de scharnierende platen 13 en 14 worden schuin gesteld om de waterstroom zonder merkbare hinder naar de propeller te leiden en vervolgens via kompartiment 12 te laten uitstromen. De zeefinrichting 15 wordt in vlakke of nagenoeg vlakke positie gesteld.When sailing in water polluted by plant growth, the sleeve 8 can be raised according to figure 6, the hinged plates 13 and 14 are set at an angle to direct the water flow to the propeller without noticeable hindrance and then let it flow out via compartment 12. The sieve device 15 is placed in a flat or substantially flat position.
Voor inspektie machinerieën, scharnierende platen en zeefinrichting kan koker 8 met aandrijvingsmachine geheel omhoog uit koker 10 worden gehaald (zie figuur 7) en kunnen vervolgens middels eenvoudige duiker handelingen zonodig de overige inspekties via koker 10 worden verricht.For inspection machines, hinged plates and sieving device, sleeve 8 with drive machine can be completely lifted out of tube 10 (see figure 7) and then, if necessary, the other inspections can be carried out via tube 10, if necessary.
