Definitions

  • the invention relates to a system for transferring liquids, in particular fuel, from one watercraft to another watercraft, in particular to an unmanned watercraft.
  • Refueling by means of a rigid boom system or by means of a probe and collecting funnel are known from aviation and have been in use for a long time.
  • the takeover of fuel is also known in the shipping industry.
  • task force suppliers are used to supply other ships in the fleet with fuel, among other things.
  • a tank hose is laid between the ships so that the ship to be refueled can bunker fuel.
  • the fuel can be for the watercraft itself or for aircraft used on the watercraft.
  • a tank adapter is known from US 2010/0236657 A1.
  • a device for occupying a ship is known from DE 2745927 A1.
  • a boom for catching and refueling a smaller watercraft is known from US Pat. No. 10,053,195 B1.
  • the object of the invention is to create a tank valve and a tank nozzle with which refueling can be carried out on the ship to be refueled even without human interaction.
  • the tank valve according to the invention is used to seal a tank nozzle from the environment and to close the tank.
  • the aim is to prevent water from entering the tank from the outside so that the tank valve can be used on a watercraft.
  • the tank valve has an inlet chamber.
  • the inlet chamber has an inlet opening for filling.
  • the inlet opening is surrounded by an inlet edge of the inlet chamber.
  • the inlet chamber further has an outlet opening, the outlet opening being connected to a tank.
  • a liquid can be conveyed from the outside via the inlet opening, in particular from a tank nozzle into the inlet chamber and via the outlet opening into the tank.
  • the tank valve has an inlet closure, the inlet closure being designed to close the inlet opening.
  • the inlet opening is closed with the inlet seal when no refueling is being carried out.
  • the inlet seal thus also closes the tank from the environment.
  • the inlet closure is arranged in the inlet chamber.
  • the tank valve has a force element, the force element pressing the inlet closure against the inlet edge with a first force from the inside towards the outside and sealing the inlet opening from the inside of the inlet chamber. So is the inlet opening is closed and the inlet chamber is sealed off from the environment in an unloaded case, i.e. without refueling.
  • the inlet closure is connected to an outer seal via a spacer element, the outer seal being arranged outside the inlet chamber. The spacer element thus protrudes through the inlet opening.
  • the outer seal can be pressed sealingly against the inlet edge with a second force from the outside in the direction of the inside, which is greater than the first force.
  • the outer seal therefore preferably has an opening into which a tank nozzle can preferably be inserted.
  • a force element can be a spring. It can also be about two magnets repelling each other, at least one of which, preferably both, are permanent magnets.
  • the force element can additionally have an active element which activates the force element when a force is applied that is greater than the first force.
  • the force element has a first permanent magnet and a current-carrying coil as a second magnet. The coil can be switched off or reversed so that no counterforce is generated or even a helping force is generated.
  • the advantage of the tank valve according to the invention is that the tank valve has a self-closing inlet chamber which can be switched into an open state with a tank nozzle.
  • the outer seal ensures that no liquid can get into the environment from the inlet chamber during the refueling process or, for example, that ambient water cannot get into the tank. Since the tank valve and the tank nozzle are shaped to match, the inlet chamber can only open when the tank nozzle is in contact. The tank valve cannot be opened, for example, by a wave strike.
  • the inlet closure and the outer seal are connected to one another via an instruction funnel.
  • the instruction funnel thus forms the spacer element.
  • the instruction funnel has openings through which liquid, in particular fuel, can be passed into the inlet chamber.
  • the second force is less than twice as great as the first force. This enables the inlet chamber to be reliably sealed during refueling in a simple manner. If the second force were much greater than the first force, a half-open intermediate position could easily be created.
  • the tank valve has at least one first fixing element.
  • the first fixing element is designed to fix a tank nozzle and to press the tank nozzle against the inlet closure and thus to press the outer seal against the inlet edge.
  • the tank valve preferably has at least three fixing elements which are arranged around the inlet opening.
  • the tank valve particularly preferably has four to eight fixing elements.
  • the fixing element is designed in the shape of a hook and can be folded laterally.
  • the first fixing element is moved hydraulically. If there are several fixing elements, these are preferably moved together.
  • the tank valve has at least one proximity sensor, the proximity sensor being designed to detect a tank nozzle.
  • the tank valve particularly preferably has a proximity sensor and at least one fixing element.
  • the proximity of a tank nozzle detected by the proximity sensor triggers the mechanism with which the fixing element detects the tank nozzle and presses it against the inlet closure.
  • the inlet chamber has lateral slots as outlet openings.
  • a collecting line for forwarding the liquid, in particular the fuel is preferably arranged around the circumference. In this way, an optimum of flow area and stability can be achieved.
  • the inlet chamber has a cylindrical basic shape. The inlet opening thus preferably has a rotationally symmetrical shape, particularly preferably a round shape
  • the invention relates to a first watercraft with a tank and a tank valve according to the invention connected to the tank.
  • the tank valve is arranged with the inlet opening facing upwards on the deck of the first watercraft.
  • a vertical arrangement is preferred. The surface of the deck always moves when there is a swell. If the tank valve is arranged vertically, this movement is approximately symmetrical and can best be compensated for. Also, the fleas compensation by the up and down of the wave movement can be better balanced.
  • the first watercraft is an unmanned watercraft.
  • the first unmanned watercraft can be autonomous or remote-controlled.
  • An autonomous watercraft can also be switched to a remote-controlled mode for the refueling process.
  • the invention relates to a fuel nozzle for refueling a first watercraft by a second watercraft.
  • the tank nozzle is used to be connected to the tank valve according to the invention in order to refuel.
  • the tank nozzle and tank valve are like a lock and key, two interlocking and interacting components, which are, however, installed separately.

  • the second connecting device can be connected to a stabilizing device which is used, for example, to reduce or prevent the tank nozzle from swinging on the lifting device.
  • a spring hose is preferably rolled into a spiral. This allows the hose to change its length very well. Lateral deflections can also be compensated for this way.

  • a line with a valve is arranged below the tank valve.
  • the valve opens before refueling and closes after refueling.
  • the valve is a two-way valve which can be switched between a first position and a second position.

In the second position, the connection to the tank is open and the connection to the disposal container is closed.
  • the two-way valve is in the first position when the trunk is coupled and is then brought into the second position after a small volume has flowed through so that fuel can get into the tank.
