Abstract

The invention relates to an underwater power station comprising a support structure for supporting the underwater power station on the bottom of the body of water as well as a machine gondola. The support structure and the machine gondola can be releasably connected to one another by means of a coupling device. The invention is characterized in that the underwater power station further comprises a boom that is pivotally hinged to the support stricture, a connection cable that has a first attachment point on the machine gondola and a second attachment point on the boom, and a cable guide that has a section which is open towards the boom.

Description

Modular underwater power station and method of assembly The invention concerns a modular underwater power station according to the preamble of claim 1 and a method of assembly.
Underwater power stations for using water current, in particular tidal current, can be formed as free-standing units with a water turbine rotating on a machine gondola, which is typically propeller-shaped. The gondola is hence fastened to a supporting structure, which is formed floating or anchored on a water bed. A modular version of such underwater power stations contains a releasable coupling device between the machine gondola and the supporting structure so that in particular for servicing a facility the components subjected to pre-determined maintenance cycles can be raised above the water surface for inspection Document EP 1366287 Al discloses an example of modular underwater power station. To do so, a machine gondola is mounted on foundations made of individual components with a supporting structure erected thereon by means of a guide cable arrangement. Safe running of the connection cable presents one of the difficulties associated with this assembly step, so as to provide connection between the electrical components of the facility and a terrestrial mains. Lowering of such a connection cable must be synchronous with machine gondola, to avoid any risk of cable wrapping up in the coupling area between the machine gondola and the supporting structure due to an excessive length of the connection cable, respectively to prevent the connection cable from running disorderly around the supporting structure of the underwater power station and in the worst case from reaching into the flight path of the water turbine. For that purpose document EP 1366287 Al afore mentioned suggest to provide a guide groove along the supporting structure for the connection cable, whereas said channel extends from a fixed section articulated on the supporting structure to the water bed via a second, foldable section.
A service diver places and fastens the connection cable after coupling of the machine gondola on the supporting structure along said guide groove. This operation would involve several divers and prove hazardous. Moreover, for each service measure requiring the machine gondola to be lifted the connection cable should be loosened from the guide groove, an operation which can only be performed by a diver according to the concept exposed above.
Document GB 2437534 A discloses a simplified variation of the cable guide.To do so, a fixed connecting sleeve extends from the machine gondola inside which a portion of the connection cable runs, whereas it is secured at a distance from the coupling device on the supporting structure as well as from the rotating installation section. Such a design still exhibits the shortcoming that the connection piece arranged freely in the surrounding flow is sufficiently stable and hence of massive construction.
Moreover, it does not reach to the water bed so that the cable guide is no determined either from the outlet of the connecting sleeve.
The object of the invention is to provide a device and a method for reliably guiding a connection cable from the machine gondola and leading usually to a national grid on land, for modular underwater power station including a machine gondola releasably fastened to the supporting structure.. The construction of this element must be simple and reliable, consequently the cable run must be automated when coupling the machine gondola to the supporting structure and dispense with the intervention of service divers.
The object of the invention is satisfied by the characteristics of the independent claim. The starting hypothesis is a cable run which is preferably in the form of a groove, which is guided along a supporting structure fixed on the water bed.
Preferably the cable guide runs in the upper section with a certain, minimum tilt against the vertical along the supporting structure so that a circuit is selected in flow shadows of the bearing portions and the resting position of the connection cable is secured in the cable guide. In the lower section, the cable run is continuously horizontal and reaches in the spout, without substantial height offset relative to the environment, the area of a hinge for a swivel-mounted boom articulated around the supporting structure.
The purpose of the boom is to run reliably the connection cable when the machine gondola is coupled and to insert it in the cable guide, which in this view is open in the direction of the boom and lies substantially in the swivel plane of the boom. In this view the connection cable is run via a first fastening point on the machine gondola and a second fastening point on the boom, whereas this second fastening point is spaced apart from the hinge of the boom on the supporting structure. Due to this arrangement of the connection cable, the lowering of the machine gondola causes a synchronous swivel movement of the boom in the direction of the coupling device on the supporting structure, which can be supported by a motorised system in a possible version. In the easiest case, the movement will however only result from the effect of the own weight of the boom according to the guiding of the length of connection cable between the first fastening point and the second fastening point. In an alternative embodiment the movement of the boom is motorised or the boom is prestressed in the laying direction. It may also be envisioned to provide a stop for guaranteeing a minimum tilt position against the vertical in the direction of the laying.
When running the connection cable from the machine gondola to a second fastening point on the boom, spaced apart from the supporting structure, this section of the connection cable is pulled sufficiently outwardly when lowering the machine gondola to reliably prevent the cable from wrapping up in the coupling device. Additionally, this section of the connection cable is inserted automatically in the guide groove. For that purpose, a sufficiently accurate orientation of the machine gondola is provided with respect to the cable guide, which is secured through a suitably designed coupling device.
Additionally, the length of connection cable between the first fastening point on the machine gondola and the second fastening point on the boom and the length of the boom must be determined so that once the machine gondola has been coupled to the supporting structure the boom substantially ends up lying on the water bed. Moreover the diving depth of the supporting structure should be paid attention to, more precisely the distance of the coupling device on the supporting structure from the water surface. In particular for great diving depths it may prove necessary, that the second fastening point of the connection cable on the boom does not include any fixed fastener but that the connection cable may be run through this second fastening point with a controlled movement. Consequently, embodiments can be envisioned for which the connection cable is picked up in the second fastening point when the machine gondola starts to be lowered by means of a device intended for that purpose, in order to continuously reduce the length of the piece of the connection cable between the first fastening point and the second fastening point in a first step of the method. If a predetermined length of this connection piece has been reached, which corresponds to a determined diving depth of the machine gondola, picking up the connection cable on the second fastening point on the boom is stopped. This operation may involve an appropriate clamping mechanism so that subsequently the length of the connection cable between the first fastening point and the second fastening point is kept unchanged and when the machine gondola of the boom is further lowered, the boom carries out the rotational movement aforementioned around the hinge installed on the supporting structure, so that the connection cable pulls in a controlled fashion and ultimately rests in the cable run.
For further running the connection cable starting from the second fastening point on the boom the connection cable is preferably returned at least along a portion of the length of the boom. Particularly preferably the connection cable runs in the boom which is formed hollow for that purpose. consequently, the exit point of the connection cable is preferably situated in the area of the hinge of the boom and runs from that point along the water bed up to mains coupling point on land.
Moreover, a strain relief is preferably provided between the first fastening point and the second fastening point. For that purpose different embodiments can be envisioned, for instance using a reinforced sheathing of the connection cable.
Additionally, cable protection elements can be used at least along the section of the connection cable between the first fastening point and the second fastening point and/or at the exit region of the connection cable on the boom.
The cable guide must be formed so that the insertion region in the cable guide can be found by rotating the boom with the connection cable. To that end the partial region of the cable guide opening up to the boom is preferably fitted with a tapered opening area, which is formed sufficiently wide for reliable introduction of the connection cable. in particular this catching region, as well as the further section of the cable guide, are preferably arranged hydraulically. A tillable grid structure may be envisaged at least in partial regions.
The invention is described more in detail below using exemplary embodiments and in connection with figure illustrations. The following details are shown: Figure 1 shows a modular underwater power station according to the invention when lowering the machine gondola.
Figure 2 shows the underwater power station of figure 1 just before coupling the machine gondola in the supporting structure.
Figure 3 shows an underwater power station according to the invention after coupling the machine gondola on the supporting structure with a connection cable inserted in the cable guide and a boom resting on the water bed.
Figure 1 is a diagrammatic representation of a modular underwater power station 1. Said station includes a supporting structure 4 resting on the water bed 5. A receptacle 12 is provided on the upper end of the supporting structure 4 in which receptacle a connection piece 13 can be inserted for coupling the machine gondola 2. To do so, the machine gondola 2 includes at least one water turbine 3, which is predominantly propeller-shaped.
A connection cable 8 extends from a first fastening point 10 on the machine gondola 2. Moreover, the connection cable 8 runs over a boom 6, which is connected with a hinge 7 and in a swivel fashion with the supporting structure 4. A second fastening point 11 is provided on the boom 6 for the connection cable 8 which is arranged so that the own weight of the oblique boom 6 sufficiently pulls the section of the connection cable between the first fastening point 10 and the second fastening point 11 and keeps this section clear from the receptacle 12 in the supporting structure 4.
Besides, a cable guide 9 in the form of a groove opening up to the boom 6 is installed on the supporting structure 4, which in the upper section runs substantially along the support column of the supporting structure 4 in flow shadows of the facility and in the lower section turns into a bent section, which emerges to the water bed 5 in the area of the hinge 7 of the boom 6. To do so, the cable guide 9 is oriented so that the connection cable 8 is laid down in the cable guide 9 by the movement of the boom 6 for angularly accurate insertion of the connection piece 13 in the receptacle 12. This can be clearly seen on figures 2 and 3.
To do so, figure 2 shows the laying position of the boom 6 on the water bed. In this assembly step the connection cable 8 is already situated close to the cable guide 9, wherein it ends up lying once the connection piece 3 has been fully lowered in the receptacle 12. The connection cable 8 is now inserted reliably and definitely.
Should service require bringing up the machine gondola 2 to the surface the machine gondola 2 can be raised from this final cable laying position, without fearing that a section of the connection cable 8 becomes entangled in the supporting structure and causes complications when raising the machine gondola.
