Description

The invention relates to an electrical holding device for holding to a metallic object.Boat hooks are known for holding to and pushing off objects, which are also referred to as peek hooks (Nautian Language). Peek hooks are versatile for a large number of different actions. A particular situation for ships that can be maneuvered with few crew members is a closure. For sluices, the ship moves into the full or empty sluice basin and when changing the level in the sluice it is necessary that at least one person on the ship constantly flies or catches strengthers on the sluice wall in order to stabilize the position of the ship in the sluice. If the ship is located during the closure next to the sluice wall which is usually heavily infested with algae, a binder cannot be easily transferred from one sheet pile to the next. Furthermore, handling with softeners on the lock wall is associated with a great deal of algal abrasion. Some exercise is required so that the person taking care of the conversion of the strengthers necessary during the transfer does not become contaminated with algae after the transfer. Persons who have little lock exercise can be wet after a closure and provided with lock wall abrasion.In the patent specification DE 315 426 A a boat pole with an electric magnetic head is disclosed. The supply of electric current to the electromagnet is left open.U.S. patent application US 2014 / 0 364 021 A1 discloses a peek hook with an additional tip made of a permanent magnet. This serves to be able to absorb water-floating strengthers with a float with a metallic plate as a magnetic element from the water.In the German laid-open specification DE 20 63 046 A a recovery device for underwater devices is disclosed. This device has, among other elements, an electromagnet which closes a valve via which a balloon is inflated. If the electrical current flow of the electromagnet is interrupted, the valve opens and inflates the balloon for recovery of the underwater device.It is an object of the invention to provide a boat pole with an electromagnet which is easy to handle.The object according to the invention is achieved by a boat hull having the features according to claim 1.According to the concept of the invention, an electric boat pole for holding to a metallic object is provided, which consists essentially of a holding pole and at least one electric magnet, wherein the at least one electric magnet is fastened to a first end of the holding pole. According to the idea of the invention, it is provided that the magnet replaces the tip of a peek hook. The electrically switchable magnet can be used to hold itself on a metal pole, on a sheet pile, on a metal hull of a larger ship or on metal constructions, such as, for example, on metal bridge pillars or on metal swimming buoys.The electric magnet can be supplied with an accumulator arrangement or with electric current via an electric cable. For this purpose, it can be provided that a cable for an electric current supply for the at least one electric magnet is arranged at a second end of the holding rod, wherein the electric current supply can be switched on and off by means of a switch in the holding rod. Since the electric magnet is not buoyant and has a relatively high dead weight, it can be provided in an advantageous embodiment of the holding device according to the invention that the electric cable is buoyant. Floatable electric cables are known from the field of pool robots. Should the electrical holding device walk outboard, the cable floats up and, if the water depth is not too deep, the electrical holding device can be resumed on the floating cable.In order to improve the retention of the at least one electric magnet on an external wall, it can be provided in an advantageous embodiment of the retaining device that the at least one electric magnet is connected to the retaining rod via a tilt-elastic element.Since the boot rod is battery-operated, it is provided that at least one electric battery is arranged in the holding rod, which battery can be charged via a contactless charging device. Thus, the holding rod can be mounted on board in a holding clamp, as is known for garden equipment, on board in a sea-proof manner. The clamping device can charge the accumulators in the holding device via a charging coil.In order to make the boat hull buoyant, it can be provided that at least one floating body is arranged in the holding hull, which floating body is dimensioned such that the entire holding device is buoyant. Thus, the support rod is protected from getting under the water should it be accidentally dropped.In order to be able to place the holding rod while waiting during the entry into the lock, a supporting pin can be arranged at the second end, on which supporting pin the holding rod can be placed. The support pin may have a ball tip that cannot puncture a deck floor.In order to avoid annoying fishing after a lost boat pole, it can be provided that a burlline is arranged at the second end.The invention is explained in more detail with reference to the following figures.It shows: FIG. 1 shows an electric boat pole according to the invention, which is outlined in an interrupted manner, in a first embodiment, FIG. 2 shows an electric boat pole according to the invention, which is outlined in an interrupted manner, in a second embodiment, FIG. 3 shows details of the electric boat pole, which can occur in both embodiments according to FIG. 1 or FIG. 2, FIG. 4 shows a boat hull according to the invention in use in the lock of a ship, FIG. 5 shows two completely illustrated boat poles in different embodiments.FIG. 1 shows an electric holding device 100 according to the invention, which is outlined in an interrupted manner, as a boat pole in a first embodiment. The electric holding device 100 as a boat pole serves to be held to a metallic object. Metallic articles may be: a metallic pole, a sheet pile, a metallic hull of a larger ship, or a metallic construction such as a metallic bridge pillar or a metallic swimming buoy. The electrical holding device 100 as a boat pole comprises a holding pole 110 having a diameter of a few centimeters, for example in the thickness of a broom stalk or somewhat more. An essential element of the electrical holding device 100 as a boat pole is that it has at least one electrical magnet 120 with which the holding to a metallic object is made possible. For this purpose, the at least one electric magnet 120 is fastened to a first end E 1 of the holding rod 110. The at least one electric magnet 110 can be actuated via the electric switch 140 integrated in the retaining rod, wherein the power supply is optionally effected via an electric cable 130. This cable has a plug for a cigarette lighter socket which provides a voltage of 12 V direct current and can be loaded up to 30 A. In order that the at least one electric magnet 120 can be flexibly attached, it is provided in an advantageous embodiment that it is connected to the holding rod 110 via a tilt-elastic element 150. Such resilient elements 150 are typically made of hard rubber and are used to suspend vibrating motors. For this purpose, they have on both sides a stud bolt, which is embedded in the hard rubber and has a thread, by means of which the resilient element 150 can be connected to the retaining rod 110 on the one hand and to the at least one electric magnet 120 on the other hand.FIG. 2 shows an electrical holding device 200 according to the invention, which is outlined in an interrupted manner, in a second embodiment. This embodiment of the inventive holding device 100 as a boat pole differs from the first embodiment in FIG. 1 in the use of a plurality of electrical magnets 220 which are arranged on a hard rubber rail. If the plurality of electric magnets 220 are supplied with electric current, all of the electric magnets 220 simultaneously engage the metallic substrate. For example, if a bollard is chosen as the stopping point, the electric magnets 220 will lay around the radius of the bollard and bend the hard rubber strip connecting the various electric magnets 220. This bending and the thus changed relative arrangement of the electric magnets 220 is shown in FIG. 2 as a dashed-line drawing. The electric switch 240 corresponds to the electric switch 140 in FIG. 1, and the support rod 210 corresponds to the support rod 110 in FIG. 1.The resilient element 250 also corresponds to the resilient element 150 in FIG. 1.FIG. 3 shows details of the electrical holding device 100 as a boat pole, which can occur in both embodiments according to FIG. 1 or FIG. 2. One or more accumulators are arranged in the handle of the holding rod 110 in order to enable wireless use of the holding device 100, 200.FIG. 4 shows how a holding device 100 according to the invention is used in the lock of a ship. A person stands on the deck of a ship and holds the holding device 100 like a peek hook. In this case, the electric magnet at the end of the retaining rod engages the sheet pile wall shown in the background. The person standing on the deck of the ship can now switch on the electric magnet to hold it and switch off the electric magnet to implement the electric holding device.FIG. 5 finally illustrates two holding devices 100, 200 shown completely as boat poles in different configurations, wherein all conceivable features are implemented in these configurations. The two holding devices 100 and 200 are fastened here to a wall for storage by the holding rod 110, 210 in a clamping device 310. In the clamping device 310, there is a charging device 300 in the form of a coil, to which electric current is applied by a cable attached to the clamping device 310. A floating body 170, 270 is located in the holding rod 110, 210 in order to provide buoyancy to the holding device 100, 200 should it fall into the water. Furthermore, accumulators 160, 260 for wireless operation are located in the holding rods 110, 210. The electric current for the electric magnets 120, 220 can be turned on and off via the switches 140, 240. The electrical cables 130, 230 connected to the retaining rods 110, 210 serve for direct supply of electrical current from a powerful on-board power grid. In order to protect the electrical cables 130, 230, it is provided here that a respective supporting pin 180, 280 is provided at the lower end of the holding rods 110, 210. This protects the electrical cables 130, 230 when the retaining rod is placed in place like a traveling rod. The support mandrels 180, 280 preferably have a ball at their lower end, which prevents the ship's deck from being punctured. In order to protect the holding devices 100, 200 from loss, it is provided in these configurations that the electrical cables 130 and 230 are buoyant. In addition, rig ropes 190 and 290 are provided, by means of which the electrical holding devices 100, 200 can be connected to the ship.LIST OF REFERENCE CHARACTERS100 Holding device 110 Holding rod 120 Electrical magnet 130 Cable 140 Switch 150 Flexible element 160 Rechargeable battery 170 Floating body 180 Supporting pin 190 Rigline 200 Holding device 210 Holding rod 220 Electrical magnet 230 Cable 240 Switch 250 Flexible element 260 Rechargeable battery 270 Floating body 280 Supporting pin 290 Rigline 300 Charging device 310 Clamping device E 1 First end E 2 Second end
