    Title: Device for plotting a floating object
    The invention relates to a device for expanding a floating power object, such as a spare boat or a liferaft, of the crane or davit type, which is arranged on a deck of the ship, in particular a sea ship, or a platform in a sea area according to the preamble of claim 1.
    A similar device is known from DE 101 51 911 A1, wherein the pivotal movement of the carrier relative to the base, which causes the outboard transfer of the floating power object, can be effected via electrical, pneumatic or hydraulic means. This should preferably take place independently of a central energy supply, in order to support operationality even in emergencies. However, further details for forming a decentralized energy supply are not specified in DE 101 51 911 A1.
    With such a construction of the drive for the pivoting movement which only has its own decentralized energy supply, the problem arises that only the decentralized energy supply can be used for the usual operation of the device. It must therefore be particularly robust and of high quality. Moreover, it is not certain that an energy supply in an emergency will actually be able to provide enough energy for the swinging movement. In the event of a breakdown, just like the vehicle electrical system, this could go out of operation.
    The on-board network, that is to say the central energy supply of electrical consumers of the seagoing vessel or the platform, usually has its own generator that is driven by a combustion machine. This installation is usually arranged in the lower part of the seagoing vessel and is therefore at risk in the event of an accident, such as in a fire or when water is made.
    It is therefore an object of the invention to provide a device according to the preamble of claim 1, which makes it possible to safely and reliably launch the floating power object under all circumstances and also in the case of damage.
    The object is achieved in that a control device is provided according to claim 1, with which the pivotal drive for the pivotal movement of the carrier can optionally be connected to the electrical on-board network of the seagoing vessel or the platform, or to an uninterrupted power supply device.
    An uninterruptible power supply device, also known as the abbreviation USV or in the English form as UPS (Uninterruptible Power Supply), is to be understood to mean an electrical device which in an emergency situation supplies a consumer with power when the normal power supply fails. In contrast to other emergency power units, the electrical power is available immediately or almost immediately. However, uninterruptible power supply devices are usually only designed for a relatively short bridging of a power outage. These are therefore limited for delivering power in energy content. Accordingly, the structural complexity is also clearly reduced compared to a device that is constantly and continuously in operation.
    In order to achieve the object according to the invention, on the one hand a usual routine operation of the device for expanding a floating power object is possible, wherein the energy supply of the swivel drive and possibly also further electric drives or consumers of the device via the on-board network of the seagoing vessel or platform. The vehicle electrical system is usually robust and powerfully constructed and is therefore also capable of enabling the davit to be repeatedly pivoted and pivoted with the floating power object, which can be a spare boat or a liferaft. On the other hand, the control device makes it possible to switch to the uninterrupted power supply device in an emergency, such as a fire or when a lot of water is made, in which the on-board network is no longer available. This is only available for these special and rare cases. This can therefore be constructed correspondingly easily and compactly, since in the event of an injury that requires leaving the sea-going vessel or the platform, it must only effect a one-time swiveling out of the floating object, such as a life raft.
    Of course, the uninterrupted power supply device can also be dimensioned such that it can also provide further drives or other functions of the device with energy for at least a short time. Such drives or functions can be, for example, the drive for lowering the floating power object or operating the coupling devices for releasing the floating power object from the coupling elements of the davit.
    The control device can be designed in such a way that the energy supply of the device, and in particular the one for swinging out the davit, automatically switches on the on-board network, as long as it is under enough voltage to supply the davit with power. The normal operation of the device is hereby realized, wherein, for example, a reserve boat with men is launched, so that it is transferred or can carry out certain tasks. Only when the on-board network fails, which is recognized by the control device via a sensor device as the occurrence of damage, does it also automatically switch to the uninterrupted power supply device (UPS). This switching can alternatively or as a replacement for automatic operation also be carried out by someone operating the device, for which a separate display and operating device is provided at the control field of the control device. This also includes manually or electrically operated switching elements that are part of the control device.
    It is clear that the actual movement of the pivoting movement of the davit must take place in all operating states by someone who operates the device, who has an overview of the situation. This must, for example, control the correct manning of the reserve boat to be deployed or the liferaft and monitor compliance with the safety regulations. Controllers, such as a keyboard or a switch, are provided for those who operate the device, which are arranged on or at least in the vicinity of the davit. The various functions of the davit and in particular the swing out into an outboard position in preparation for the celebration are set in motion via these operating elements. It is also possible to remotely control the functions of the davit, at least swing out of the outboard, such as via radio or infrared. Electric cable remote controls or mechanical coupling members can also be used for this purpose, such as cable hoists or bowden cables. These different handling means can preferably be operated from the deck or from optionally the rescue means or reserve boat to be deployed.
    For extreme emergencies where the emergency power supply of the davit also fails, or for maintenance purposes, it is advantageous if a possibility for manual operation of at least the swiveling movement of the davit is available. These means can for instance comprise a transmission which can be operated via a hand crank and which engages in a gear wheel in the base of the carrier of the davit, in order to bring it into a pivoting movement relative to each other, the pivoting.
    In the uninterrupted power supply device (UPS) according to the invention, rechargeable accumulators or power-efficient capacitors are advantageously used. These are compact and require little maintenance and are available in practically random energy storage capacities.
    The uninterruptible power supply device is preferably connected to the on-board network of the seagoing vessel or the platform. This guarantees that it can be kept constantly in a fully loaded condition. It is understandable that in the case of an alternating-voltage operation of the on-board network inverters must be provided which are capable of supplying the required voltage and current values for maintaining the charging state. Alternatively or additionally, it may be advantageous to connect the uninterruptible power supply device to a solar cell device or to a wind-driven generator. These can compensate for the slight temporary drop in the voltage of the components of the accumulator or the capacitor in the uninterrupted power supply device. These are possibly preferably arranged at the interpreter of the davit.
    The uninterruptible power supply device, at least the essential components such as the accumulator or the capacitor, is preferably arranged in a protected area of the seagoing vessel or platform that is in the vicinity of the davit to be driven. This area may consist of a fixed housing which provides mechanical protection of the weather or seawater and which is fixedly mounted, for example, to the carrier or the interpreter of the davit. However, the area can also lie below the deck in the vicinity of the davit and is preferably protected against the influence of heat, as can sometimes occur in the event of a fire under the deck.
    The invention is described below with reference to the exemplary embodiments according to figures 1 and 2. In the drawing:
    FIG. 1: A perspective view of a device according to the invention in a schematic representation; and
    FIG. 2: a schematic circuit plan of a control device according to the invention.
    Figure 1 shows an embodiment of the device 1 according to the invention for expanding a floating object 2. The object 2 is shown here as a dinghy, for example it must also represent other types of floating objects such as, in particular, a lifeboat, a spare boat or a liferaft. The device 1 is constructed according to the type of a crane or a davit 3 and is mounted on deck 4 of a seagoing vessel or of a platform located in a sea area. The davit comprises a base 5 mounted on the deck 4, a support 6 disposed there, which are connected to each other via a pivot bearing 7. The carrier 6 is pivotable relative to the base 5 about an axis substantially perpendicular to the deck 4. "Substantially perpendicular" in this context means that the pivot axis can also be arranged more or less obliquely with respect to perpendicular, as is known from the publication DE 101 51 911 A1 mentioned at the outset. The orientation of the pivot axis is not important for the invention. The only important thing is that as a result of the pivoting movement of the davit 3 the floating power object 2 comes to lie so far outboard of the deck 4 that it can be celebrated without danger.
    For pivoting the pivot, a pivoting drive is available, which has an electric motor 9 and transmission 10, which is arranged on the carrier 5 according to figure 1. The transmission 10 engages in a pinion located on the pivot bearing 7 or a gear wheel and, upon activation of the pivot drive 8, causes a rotation of the carrier 6 relative to the base 5 and thus relative to the deck 4. At the A hoisting arm 11 is available at the upper end of the carrier 6, which arm extends laterally and obliquely upwards from the carrier 6 over the deck 4. The carrier 6 and the hoisting arm 11 together form a crane or a davit 3. At the end region 12 remote from the carrier 4 a roller is available as diverting element 13, which is used for diverting a coupling element 14 for the connection of the object to be expanded. 2 with the davit. The coupling element 14 is, as usual, arranged as a wire cable and terminates at one end in a coupling device 15 for connecting to the object 2. The other end of the coupling element is connected to a motor or manually driven winding device 16 which for celebrating or retrieving is provided with floating object 2.
    A control device 20 is mounted in a housing 31 on the carrier 6 of the davit 3. This comprises the uninterruptible power supply device 22 as well as a transformer 32, which converts the voltage supplied from the on-board network 21 to a value suitable for supplying the uninterruptible power supply device 22. The control device 20 is connected with lines 28 both to the on-board network 21 and via the uninterruptible power supply device 22 to the motor 9 of the pivoting drive 8.
    The uninterruptible power supply device 22 has an accumulator (not shown) or a capacitor with a high energy storage capacity as energy storage, as well as further electrical components such as rectifiers, intermediate circuits and inverters, also not shown. These units serve on the one hand to form an energy storage that can drive the pivoting movement of the davit 3 in an emergency. On the other hand, in normal operation of the davit 3, these can provide the various motors of the davit 3 with drive energy.
    The main structure of an uninterruptible power supply device 22 is known to those skilled in the art and does not need to be further explained here. However, it is important that the control device 20 is designed so that it detects a failure of the on-board network 21 via a sensor (not shown in Figure 1) and then falls back on the energy storage of the uninterruptible power supply device 22, so that the energy is at least swung out once. make the davit 3 and thus the floating object 2 outboard relative to the seagoing vessel or the platform. This pivoting can be triggered in an emergency by the person responsible for this who operates the device by operating operating elements (not shown). The operating elements, such as keyboard or switch, as well as display elements are parts of the control device 20 and are arranged, for example, on the housing 31 of the control device 20, which, however, is not shown in Figure 1.
    The supply of the uninterruptible power supply device 22 can, according to the invention, take place via the on-board network 21, for which there are available in the control device 20 not only the converter 32 but also further electrical or electronic components which charge the energy storage of the uninterruptible power supply device. 22 to bring about and maintain it. Such components, which essentially form an alternating current-operated DC voltage-charging device, are known to those skilled in the art and are therefore not further explained here.
    Alternatively or additionally to charging the energy storage in the uninterruptible power supply device 22 via the on-board network 21, charging with the aid of renewable energies is also possible. Representative of this, Figure 1 shows a solar cell device 25 on the interpreter 11 of the davit 3. The use of a wind-driven generator is also possible. Since the temporary energy losses of the energy storage of the uninterruptible power supply device 22 are very small, said charging aids can be dimensioned small, since they only have to provide a relatively small power.
    Figure 2 shows in a schematic illustration a diagram for driving a davit 3 with an uninterruptible power supply device 22. A transformer 32 is supplied from the on-board network 21, which transforms the alternating voltage of the respective on-board network 21 into 230 volts alternating voltage, insofar as this is not anyway all the tension of the on-board network. A lead leads from the transformer 32 to the uninterruptible power supply device 22 and, via a non-shown charging device, provides for charging and maintaining the energy storage 26 of the uninterruptible power supply device 22, which is shown here schematically and as an example as an accumulator battery. Charging can also be effected by a regenerable energy source, which is shown here as solar cell device 25.
    A further line leads to the control device 20 and via this to a voltage-frequency converting unit 36, which is connected to the motor 9 on the swivel drive 8. The control device has a sensor, not shown here, which determines whether the on-board network 21 is active or has failed due to damage. In the latter case, the control device 20 activates via switching elements (not shown), such as a switch or a relay, an uninterruptible power supply device 22 which is now ready to take over the voltage supply from the voltage-frequency converter 36. At the same time, an optical and / or acoustic signal is output via the display unit 30 of the control device 20, such as via an indicator lamp or a signal tone by means of a horn. The electrical energy required for this is also supplied by the uninterruptible power supply device 22.
    Switching elements 27 are available in the housing 31 of the control device 20, which make it possible to at least activate the swiveling out of the davit 3 in an emergency. Conveniently, however, the other operating and display elements required for operation of the davit 3 during normal use are also arranged in this housing 31. Furthermore, the control device 20 shows an input for a remote control 34 and for a radio or infrared remote control, which is indicated in Figure 2 by the antenna 38.
    It will be clear that the parts transformer 32, uninterruptible power supply device 22, control device 20 and voltage-frequency converting unit 36 shown in Figure 2 can be accommodated in a common housing. Alternatively, the uninterruptible power supply device 22 and / or the voltage to frequency unit 36 may also be arranged under the deck where they are better protected against weather or water.
