Description
Oppfinnelsen vedrører en innretning for berging av et ubemannet undervannsfartøy, av den i innledningen til patentkrav 1 definerte type. The invention relates to a device for salvaging an unmanned underwater vessel, of the type defined in the introduction to patent claim 1.
Ved en kjent bergingsinnretning av denne type (DE 195 44 656 Cl) er den på fartøyet anordnede bergingsdel utformet som et øre mens den til løfteinnretningen tilknyttede In the case of a known salvage device of this type (DE 195 44 656 Cl), the salvage part arranged on the vessel is designed as an ear, while the one connected to the lifting device
fanginnretning er utformet som en krankrok, festet til et fra en kranarmende senkbart og hevbart tau. For under bergingen å redusere antall feilkoblinger mellom undervannsfar-tøyet og fanginnretningen når krankroken skal tres inn i øret, benyttes det for fremføring av krankroken mot øret en fangline, som i endene er festet til krankroken og ved hjelp catch device is designed as a crane hook, attached to a rope that can be lowered and raised from a crane arm. In order to reduce the number of misconnections between the underwater vessel and the catching device during the salvage when the crane hook is to be threaded into the ear, a fishing line is used to advance the crane hook towards the ear, which is attached to the crane hook at the ends and with the help of
av en fra kranarmenden utragende utligger, kan legges ut i en linebue ned mot vannflaten. Fanglinen er ført gjennom en på utliggeren ved hjelp av et forlengbart, elastisk tøyningselement festet griper, som er utformet slik at den åpner seg selvstendig for fri-giving av fanglinen når den i øret innførte fangline er strukket etter en oppspoling. of an outrigger protruding from the crane arm, can be laid out in an arc of line down towards the water surface. The fang line is led through a gripper attached to the outrigger by means of an extendable, elastic stretching element, which is designed so that it opens independently to release the fang line when the fang line inserted in the ear is stretched after a reel.
En slik bergingsinnretning virker ganske pålitelig, også under sjøgangsbetingelser, for styrte undervannsfartøy i den øvre vekstklasse, dvs. mer enn 500 kg. Such a recovery device seems quite reliable, also under seagoing conditions, for steered underwater vessels in the upper growth class, i.e. more than 500 kg.
Ved en likeledes kjent bergingsinnretning (DE 197 45 088 Al) er fanginnretningen utformet som en bergingsruse, som er anordnet på den frie enden til et med sitt fotpunkt In the case of a similarly known recovery device (DE 197 45 088 Al), the capture device is designed as a recovery device, which is arranged on the free end of a with its base
nær vannflaten ved bergingsskipets side avstøttet og om fotpunktet svingbart bærestativ. Etter at bergingsrusen er senket til vannflaten, blir undervannsfartøyet, som i den nevnte publikasjonen benevnes som "UnterwasserlaufkOrper", ført inn i rusen gjennom ruseåpningen og stoppet der, hvoretter bærestativet svinges opp igjen, slik at undervannsfar-tøyet kan tas ut fra rusen om bord i bergingsskipet. close to the surface of the water at the side of the salvaging vessel supported and swiveling about the base. After the recovery float has been lowered to the water surface, the underwater vessel, which in the aforementioned publication is referred to as "UnterwasserlaufkOrper", is brought into the float through the float opening and stopped there, after which the support stand is swung up again, so that the underwater vessel can be removed from the float on board in the salvage ship.
En slik bergingsinnretning benyttes for berging av lette undervannsfartøy, men det er relativt vanskelig å treffe og føre undervannsfartøyet inn i ruseåpningen, særlig i sjø-gang, og bergingen krever en viss øvelse. Such a salvage device is used for the salvage of light underwater vessels, but it is relatively difficult to hit and guide the underwater vessel into the ruse opening, especially in sea-going, and the salvage requires a certain amount of practice.
Hensikten med oppfinnelsen er å tilveiebringe en bergingsinnretning for lette under-vannsfartøy, eksempelvis med en vekt på 50 kg eller mindre, med hvilken bergingsinnretning undervannsfartøyet på en enkel og pålitelig måte kan opptas i vannflaten i nærheten av bergingsplattformen og hives om bord i bergingsplattformen. The purpose of the invention is to provide a salvage device for light underwater vessels, for example with a weight of 50 kg or less, with which salvage device the underwater vessel can be taken up in a simple and reliable way in the water surface near the salvage platform and lifted on board the salvage platform.
Denne hensikt oppnås med de trekk som er angitt i patentkrav 1. This purpose is achieved with the features specified in patent claim 1.
Innretningen ifølge oppfinnelsen, for berging av et ubemannet, fjernstyrt undervannsfar-tøy, har den fordel at fanginnretningens nettutførelse gir en stor trefflate for tilveie-bringelse av koblingen mellom undervannsfartøyet og fanginnretningen, hvorved pålite-ligheten til den for bergingen avgjørende kobling mellom undervannsfartøy og fanginnretning økes også under ugunstige betingelser, eksempelvis ved sjøgang og/eller når personalet er lite øvet. Da den på undervannsfartøyets overside, som trenger opp gjennom vannflaten, plasserte bergingskrok kan fanges opp i en hvilken som helst nettmas-ke, vil også en mindre nøyaktig manøvrering av det fjernstyrte undervannsfartøyet gi en kobling til fanginnretningen. Så snart forbindelsen mellom nettet og bergingskroken er tilveiebrakt, kobles undervannsfartøyet av, samtidig som nettet bringes inn. Selv om koblingen skulle slå feil som følge av en dårlig manøver, vil en slik feilaktig kobling ikke medføre noen fare, fordi bergingsnettet ikke har noen kollisjonsmasse av betyd-ning. Koblingsforsøkene kan derfor avbrytes og gjenopptas vilkårlig mange ganger. The device according to the invention, for salvaging an unmanned, remote-controlled underwater vessel, has the advantage that the capture device's net design provides a large impact surface for providing the connection between the underwater vessel and the capture device, whereby the reliability of the connection between the underwater vessel and the capture device, which is crucial for the salvage is also increased under unfavorable conditions, for example when going to sea and/or when the staff is not very experienced. Since the salvage hook placed on the upper side of the underwater vessel, which penetrates through the surface of the water, can be caught in any net mesh, a less precise maneuvering of the remote-controlled underwater vessel will also provide a connection to the capture device. As soon as the connection between the net and the recovery hook is established, the underwater vessel is disconnected, at the same time as the net is brought in. Even if the coupling should fail as a result of a poor manoeuvre, such an incorrect coupling will not cause any danger, because the recovery net has no significant collision mass. The connection attempts can therefore be interrupted and resumed any number of times.
Hensiktsmessige utførelsesformer av den nye bergingsinnretningen, med fordelaktige videreutviklinger og utforminger av oppfinnelsen, er angitt i de ytterligere patentkrav. Appropriate embodiments of the new salvage device, with advantageous further developments and designs of the invention, are specified in the further patent claims.
Ifølge en fordelaktig utførelsesform av oppfinnelsen er bergingsnettet forbundet med løfteinnretningen ved hjelp av en bergingsline og er forsynt med oppdriftslegemer. Den fritt valgbare linelengde mellom bergingsplattformen og det flytende bergingsnett mu-liggjør en utstrakt frikobling av bergingsnettet med hensyn til bergingsplattformens bevegelser. Ved sjøgang og betydningsløs strømning kan man gi en slakk line, og ved sporbar strømning og samtidig sjøgang kan det hensiktsmessig benyttes en lang line, som eliminerer en flytende bergingsplattforms vertikale bevegelser relativt bergingsnettet. Som følge av de på bergingsnettet anordnede oppdriftslegemer vil bergingsnettet være utspent i en plan flytetilstand og undervannsfartøyet kan lett kjøre inn under nettflaten og således med sin bergingskrok fanges opp i en av nettmaskene. Fortrinnsvis er bergingskroken slik anordnet på undervannsfartøyet at krokåpningen er rettet mot un-dervannsfartøyets hekk. Fangingen av bergingskroken i nettet oppnås da ved å koble ut undervannsfartøyets drift eller ved å kjøre undervannsfartøyet akterover. According to an advantageous embodiment of the invention, the salvage net is connected to the lifting device by means of a salvage line and is provided with buoyancy bodies. The freely selectable line length between the salvage platform and the floating salvage net enables extensive decoupling of the salvage net with respect to the salvage platform's movements. In the case of rough seas and insignificant currents, a slack line can be provided, and in case of traceable currents and simultaneous seas, a long line can be appropriately used, which eliminates a floating salvage platform's vertical movements relative to the salvage net. As a result of the buoyancy bodies arranged on the salvage net, the salvage net will be stretched out in a level floating state and the underwater vessel can easily drive under the surface of the net and thus be caught with its salvage hook in one of the net meshes. Preferably, the salvage hook is arranged on the underwater vessel in such a way that the hook opening is directed towards the stern of the underwater vessel. The capture of the salvage hook in the net is then achieved by disconnecting the underwater vessel's operation or by driving the underwater vessel astern.
Ifølge en foretrukket utførelsesform av oppfinnelsen har nettet en trekantform, idet bergingslinen er festet til en nettspiss og bestykkingen av bergingsnettet med oppdriftslegemer er foretatt langs den nettkant som ligger overfor festepunktet. According to a preferred embodiment of the invention, the net has a triangular shape, the salvage line being attached to a net tip and the rigging of the salvage net with buoyancy bodies is carried out along the net edge opposite the attachment point.
For å muliggjøre en berging når enten det forekommer strøm eller ikke, er bergingsnettet ifølge en fordelaktig utførelsesform av oppfinnelsen avstivet langs de fra bergingsli-nens festepunkt og mot den med oppdriftslegemer bestykkede nettkant førende nettkanter, slik at bergingsnettet beholder sin trekantform også i en kreftefri og flytende tilstand (ved manglende strøm). Avstivningene er elastisk bøyelige og foreligger fortrinnsvis i form av ved nettkantene anordnede flberglasstaver. In order to enable a salvage whether there is current or not, the salvage net is, according to an advantageous embodiment of the invention, stiffened along the net edges leading from the attachment point of the salvage line and towards the net edge equipped with buoyancy bodies, so that the salvage net retains its triangular shape also in a force-free and liquid state (in case of lack of power). The stiffeners are elastically flexible and are preferably in the form of fiberglass rods arranged at the net edges.
Oppfinnelsen skal nå forklares nærmere under henvisning til tegningen som viser utfø-relseseksempler og hvor rent skjematisk Figur 1 viser en situasjon under berging av et undervannsfartøy ut fra en flytende bergingsplattform, The invention will now be explained in more detail with reference to the drawing which shows examples of implementation and where purely schematically Figure 1 shows a situation during the salvage of an underwater vessel from a floating salvage platform,
Figur 2 viser et forstørret riss av utsnittet II i Figur 1, Figure 2 shows an enlarged view of section II in Figure 1,
Figur 3 viser et hekkriss av en bergingsplattform med en bergingsinnretning ifølge et ytterligere utførelseseksempel, og Figure 3 shows a stern view of a recovery platform with a recovery device according to a further exemplary embodiment, and
Figur 4 viser et grunnriss av et bergingsnett i den i figur 3 viste bergingsinnretning. Figure 4 shows a ground plan of a recovery net in the recovery device shown in Figure 3.
I den i figur 1 skisserte situasjon ved en berging, blir et med egen drift forsynt og fjernstyrt undervannsfartøy 11, som eksempelvis kan være en såkalt drone for minesøking og -ødeleggelse, opptatt ved hjelp av en bergingsinnretning i nærheten av en flytende bergingsplattform 12 og løftet opp fra vannflaten 13 og over på bergingsplattformen 12. Bergingsplattformen 12 er som regel et overflateskip, hvor undervannsfartøyet (dronen) tas med som hjelpefartøy og settes ut i vannet når det skal anvendes, idet undervannsfar-tøyet etter avsluttet innsats styres tilbake til moderskipet og innfanges der ved hjelp av bergingsinnretningen. In the situation outlined in Figure 1 during a salvage operation, a self-powered and remote-controlled underwater vessel 11, which can for example be a so-called drone for mine search and destruction, is captured by means of a salvage device in the vicinity of a floating salvage platform 12 and lifted up from the surface of the water 13 and onto the salvage platform 12. The salvage platform 12 is usually a surface ship, where the underwater vessel (drone) is brought along as an auxiliary vessel and put into the water when it is to be used, as the underwater vessel is steered back to the mother ship after the end of the effort and captured there using the recovery device.
Den på bergingsplattformen 12 anordnede bergingsinnretning innbefatter en fanginnretning 14, som samvirker med en på den gjennom vannflaten 13 ragende overside av un-dervannsfartøyet 11 anordnede bergingsdel 15, så vel som en løfteinnretning 16, hvor-med fanginnretningen 14 kan senkes fra bergingsplattformen 12 ned til vannflaten 13 og hives igjen fra vannflaten 13 opp til bergingsplattformen 12. Som det større utsnitt i figur 2 viser, er bergingsdelen 15 på fartøyet utformet som en fangkrok 17. Denne fangkrok er orientert slik at krokåpningen 171 er rettet mot undervannfartøyets 11 hekk. Fanginnretningen 14 innbefatter et i hovedsaken plant, flytende nett 18, heretter kalt bergingsnett 18, som ved hjelp av en bergingsline 19 er forbundet med løfteinnretningen 16. I utførelseseksempelet i figur 1 har bergingsnettet 18 en rettvinklet firkantform og er festet til en tverrstang 20 ved den enden hvor bergingslinen er tilknyttet. Tverrstangen 20 er i begge ender forsynt med flottører eller oppdriftslegemer 26, slik at tverrstangen 20 flyter på vannflaten 13. Bergingslinen 19 angriper midt på tverrstangen 20, og for utlegging av bergingsnettet 18 kreves det en med pilen 22 antydet strømning, som eksempelvis kan tilveiebringes ved at bergingsplattformen 12 beveger seg litt forover eller ved at det foreligger sjøgang. Fordelaktig kan bergingsnettet 18 være fremstilt av flytedyktig materiale, eller det kan ved den relativt tverrstangen 20 bakre nettkant være forbundet med her ikke viste oppdriftslegemer, for derved å bedre den plane flytestilling eller svømmestilling. Av den på bergingsplattformen 12 monterte løfteinnretning 16 er i figur 1 bare en utligger 23 vist. Utliggeren kan eksempelvis være en bom. På utrigge-rens 23 fritt utragende ende er bergingslinen 19 ført over en omstyringsskive 24. Ved hjelp av en ikke vist vinsj kan bergingslinen 19 fires eller hales inn. The salvage device arranged on the salvage platform 12 includes a capture device 14, which cooperates with a salvage part 15 arranged on the upper side of the underwater vessel 11 protruding through the water surface 13, as well as a lifting device 16, with which the capture device 14 can be lowered from the salvage platform 12 down to the water surface 13 and is raised again from the water surface 13 up to the salvage platform 12. As the larger section in figure 2 shows, the salvage part 15 on the vessel is designed as a grappling hook 17. This grappling hook is oriented so that the hook opening 171 is directed towards the stern of the underwater vessel 11. The catching device 14 includes a mainly flat, floating net 18, hereinafter called salvage net 18, which is connected to the lifting device 16 by means of a salvage line 19. In the embodiment in Figure 1, the salvage net 18 has a right-angled square shape and is attached to a crossbar 20 at the the end where the recovery line is connected. The transverse rod 20 is provided at both ends with floats or buoyancy bodies 26, so that the transverse rod 20 floats on the surface of the water 13. The salvage line 19 attacks the middle of the transverse rod 20, and for laying out the salvage net 18 a flow indicated by the arrow 22 is required, which can for example be provided by that the salvage platform 12 moves slightly forward or that there is a seaway. Advantageously, the rescue net 18 can be made of buoyant material, or it can be connected to buoyancy bodies not shown here at the relative crossbar 20 rear net edge, in order to thereby improve the level floating position or swimming position. Of the lifting device 16 mounted on the salvage platform 12, only one outrigger 23 is shown in Figure 1. The outrigger can, for example, be a boom. On the freely protruding end of the outrigger 23, the salvage line 19 is guided over a diverting disc 24. With the help of a winch, not shown, the salvage line 19 can be hauled in or hauled in.
For berging av undervannsfartøyet 11 styres dette slik i retning av bergingsnettet 18 at fartøyet kommer inn under bergingsnettet 18. Så snart undervannsfartøyet 11 befinner seg med sin fangkrok 17 et eller annet sted under nettflaten, reduseres farten og fartøyet bakkes eventuelt slik at det skjer en bakoverrettet bevegelse relativt fangnettet 18. Som følge herav vil fangkroken 17 hake seg opp i en av nettmaskene. Så snart en slik innha-king av fangkroken 17 har funnet sted i bergingsnettet 18, kobles driften av undervanns-fartøyet 11 ut. Samtidig hales bergingslinen 19 inn ved hjelp av løfteinnretningens 16 vinsj, slik at bergingsnettet 18 ved slutten av innhalingen vil henge i bommen 23 med det i nettet fangede undervannsfartøy 11. Bommen kan så svinges inn eller trekkes inn over bergingsplattformen 11. Bergingsnettets 18 bærekapasitet tilpasses undervannsfar-tøyets 11 vekt. For salvage of the underwater vessel 11, this is controlled in the direction of the salvage net 18 so that the vessel enters under the salvage net 18. As soon as the underwater vessel 11 is located with its grappling hook 17 somewhere below the surface of the net, the speed is reduced and the vessel is possibly banked so that a backwards direction occurs movement relative to the catch net 18. As a result, the catch hook 17 will hook into one of the net meshes. As soon as such hooking of the grappling hook 17 has taken place in the salvage net 18, the operation of the underwater vessel 11 is switched off. At the same time, the salvage line 19 is hauled in using the winch of the lifting device 16, so that at the end of hauling in, the salvage net 18 will hang in the boom 23 with the underwater vessel 11 caught in the net. -the 11 weight of the cloth.
I det i figurene 3 og 4 viste utførelseseksempel av bergingsinnretningen er løfteinnret-ningen 16 vist mer detaljert, og den med løfteinnretningen 16 via fanglinen 18 forbund-ne fanginnretning 14, som også her er utformet som bergingsnett 18, er modifisert. Utliggeren 23 er utformet som en teleskoparm 25, som kan kjøres ut fra bergingsplattformens 12 side, slik at teleskoparmens 25 fremre ende med den der anordnede styreskiven 24 får en tilstrekkelig stor avstand fra bergingsplattformens 12 side ved en bergingsope-rasjon. En vinsj 27 for bergingslinen 19 er anordnet på teleskoparmens 25 underside. I figur 3 er teleskoparmen 25 vist i en inntrukket stilling (posisjon A) og i en utskjøvet stilling (posisjon B). I den utskjøvne posisjon B er bergingslinen 19 firt og bergingsnettet 18 flyter på vannflaten 13. Til bergingsnettet 18 er det også knyttet en holdeline 28, hvis andre ende er tilknyttet bergingsplattformen 12, fortrinnsvis ved at en betjenings-person 29 holder holdelinen. Ved hjelp av denne holdeline 28 kan det på vannflaten 13 flytende bergingsnett 18 dirigeres til i nærheten av bergingsplattformen 12, og en bevegelse av den hengende last ved opptrekkingen av bergingsnettet 18 og undervannsfar-tøyet 11 kan bremses. In the embodiment of the salvage device shown in figures 3 and 4, the lifting device 16 is shown in more detail, and the catching device 14 connected to the lifting device 16 via the fishing line 18, which is also here designed as a salvage net 18, has been modified. The outrigger 23 is designed as a telescopic arm 25, which can be extended from the side of the salvage platform 12, so that the front end of the telescopic arm 25 with the guide disc 24 arranged there gets a sufficiently large distance from the side of the salvage platform 12 during a salvage operation. A winch 27 for the salvage line 19 is arranged on the underside of the telescopic arm 25. In Figure 3, the telescopic arm 25 is shown in a retracted position (position A) and in an extended position (position B). In the extended position B, the salvage line 19 is loose and the salvage net 18 floats on the surface of the water 13. A holding line 28 is also attached to the salvage net 18, the other end of which is connected to the salvage platform 12, preferably by an operator 29 holding the holding line. With the help of this holding line 28, the salvage net 18 floating on the surface of the water 13 can be directed to the vicinity of the salvage platform 12, and a movement of the suspended load when the salvage net 18 and the underwater vessel 11 is pulled up can be slowed.
Som vist i figur 4, er bergingsnettet 18 trekantformet, idet bergingslinen 19 er festet til en nettspiss 181 og det langs den relativt nettspissens 181 motliggende nettkant 182 er anordnet et antall oppdriftslegemer 21, slik at undervannsfartøyet 11 derved lett kan kjøre inn under nettflaten til det flytende bergingsnett 18. I tillegg kan ytterligere oppdriftslegemer 26 være anordnet ved nettspissen 181, for ved firt bergingsline 19 å kom-pensere for vekten til forbindelsesinnretningen mellom bergingslinen 19 og nettspissen 181 og for å hindre at nettspissen 181 synker og bergingsnettet 18 derved får en uønsket skråstilling. For å muliggjøre en berging både med og uten strømning i vannet, er de to fra nettspissen 181 mot nettkanten 182 forløpende nettkanter 183 og 184 elastisk bøye-lig avstivet, idet det der fortrinnsvis er inntrukket fiberglasstaver i nettkantene 183 og 184. As shown in Figure 4, the rescue net 18 is triangular in shape, with the rescue line 19 attached to a net tip 181 and a number of buoyancy bodies 21 are arranged along the relative net edge 182 opposite the net tip 181, so that the underwater vessel 11 can thereby easily drive under the net surface of the floating salvage net 18. In addition, additional buoyancy bodies 26 can be arranged at the net tip 181, in order to compensate for the weight of the connection device between the salvage line 19 and the net tip 181 when the salvage line 19 is loose and to prevent the net tip 181 from sinking and the salvage net 18 thereby getting an unwanted oblique position. In order to enable a salvage both with and without flow in the water, the two net edges 183 and 184 extending from the net tip 181 towards the net edge 182 are elastically braced, with fiberglass rods preferably drawn into the net edges 183 and 184.
Bergingen av undervannsfartøyet 11 med en bergingsinnretning som i figur 3 og 4, skjer på samme måte som beskrevet foran i forbindelse med figur 1. The salvage of the underwater vessel 11 with a salvage device as in figures 3 and 4 takes place in the same way as described above in connection with figure 1.
