Definitions
- Buoyancy modification module for a modular underwater vehicle
- the invention relates to a buoyancy modification module for a modular underwater vehicle and an underwater vehicle.
- Modular watercraft are usually put together in a mission-typical way and consist of different modules that take on different functions.
- the various modules are connected to one another in a similar way to standard containers.
- the modules usually have standardized external dimensions and connecting elements.
- the type and number of modules can be easily selected and simply connected to form an underwater vehicle depending on the mission.
- the mass and thus the buoyancy of the modular watercraft can change during the mission.
- the modular watercraft can hold objects, for example rock samples, measuring devices, raw materials, waste and much more.
- the modular watercraft can deliver objects, for example measuring devices, consumables (for example fuel for underwater equipment), smaller autonomous underwater vehicles and much more.
- Buoyancy within the meaning of the invention can be positive or negative. Negative lift is also called downforce.
- a modular watercraft with at least one utility element and two first bow elements is known from DE 10 2017 200 078 A1.
- a method for controlling a buoyancy control device is known from WO 2016/026894 A1.
- a device for pressing a buoyancy tank is known from DE 10 2010 047 677 A1.
- a configurable underwater vehicle is known from WO 2009/008880 A1.
- the object of the invention is to create a module with which the buoyancy of a modular underwater vehicle can be modified in order to compensate for the pick-up or release of objects.
- the buoyancy modification module according to the invention for a modular underwater vehicle has at least one first frame, the frame being designed to connect the buoyancy modification module to further modules.
- the buoyancy modification module is flushed with water. This means that unused spaces in the buoyancy modification module are buoyancy-neutral.
- the entire module does not have to be designed as a pressure body, which would be problematic, for a simple combination of modules, for example a cuboid basic shape of the module, is optimal, which, however, a pressure body is not optimal.
- the frame can actually be designed as a framework in the form of the edges of a cuboid. This enables the modules to be easily connected in all three spatial directions.
- the buoyancy modification module has at least one first pressure hull, the first pressure hull having at least one first flood area. At least one first pump is arranged in the buoyancy modification module, the first pump being able to convey water from the surroundings or a buoyancy-neutral reservoir into the first flood area and from the first flood area into the surroundings or a buoyancy-neutral reservoir.
- the system is comparatively simple. However, it is disadvantageous that the pump itself and also the first flood area are thus exposed to the effects of the surrounding water. Impurities, corrosion and growth are particularly relevant.
- a buoyancy-neutral reservoir can, for example, have the shape of a balloon. However, this changes the volume. In addition, the elastic materials used for this age comparatively quickly, which increases the risk of failure. The space requirement must also be taken into account in the construction.
- the frame has a basic shape which corresponds to a straight prism with a regular square as the base.
- the frame has a cuboid basic shape, a cuboid being a straight prism with a rectangle as the base area.
- the first pressure body has at least one first drying area, the at least one first pump being arranged in the first drying area
- the arrangement of the first pump in the first dry area inside the first pressure hull enables the use of a simpler pump, which is not is exposed to both the ambient water and the ambient pressure as well as the resulting changing ambient conditions.
- the buoyancy modification module has at least one first gas area, the first gas area being connected to the first flood area.
- the first gas area has a first gas pressure when the first flood area is completely emptied. Furthermore, when the first flood area is completely flooded, the first gas area has a second gas pressure. The difference between the first gas pressure and the second gas pressure results from the reduction in the space available for the gas in the first gas region.
- the first flood area and the first gas area form a common space.
- the first flow region 2/3 represents this common area and the first gas region 1/3, so is this common space flooded maximum 2/3 system.
- this would triple the gas pressure between the emptied state and the flooded state.
- the separation between the first Flood area and the gas area take place purely in terms of control technology, for example through the pressure change inside.
- the buoyancy modification module has at least one second gas area, the first gas area and the second gas area being connected to one another in a gas-carrying manner.
- the first gas area is arranged in the first pressure hull and the second gas area is arranged outside the first pressure hull.
- the second gas region is arranged in a second pressure body.
- the second pressure body particularly preferably forms the second gas region.
- the second pressure body is a pressurized gas cylinder.
- the buoyancy modification module can also have more than one second gas area.
- two, three, four, six, eight or ten commercially available gas pressure bottles can form second gas areas.
- the first gas area and the second gas area are connected via a first gas pump.
- the resulting gas pressure results from the reduction or increase in the available volume.
- a pressure difference can be generated by a gas pump.
- the pressure acting against the first pump during flooding can be reduced in order to save power there.
- the disadvantage is the increase in the complexity of the system.
- the first gas area and the second gas area are connected via a first valve, the first valve preventing the penetration of liquid into the second gas area.
- the first valve is a check valve or another one-way valve.
- the first gas area has a first gas pressure when the first flood area is completely emptied, the first gas pressure corresponding to half the maximum immersion pressure. This pressure has proven to be optimal to keep the performance of the first pump at the lowest possible level and thus to save energy.
- the first gas area has a second gas pressure when the first flood area is completely flooded, the second gas pressure corresponding to 1.5 times the maximum immersion pressure. This pressure has proven to be optimal to keep the performance of the first pump at the lowest possible level and thus to save energy.
- the first gas area when the first flood area is completely emptied, has a first gas pressure, the first gas pressure corresponding to half the maximum immersion pressure, and when the first flood area is completely flooded, a second gas pressure, the second gas pressure being 1.5 times the maximum immersion pressure .
- This combination has proven to be optimal for keeping the performance of the first pump at the lowest possible level and thus saving energy.
- the first gas area and the first drying area are connected to one another in a gas-carrying manner. This allows the volume surrounding the first pump to be used. At the same time, the first pump remains dry. A somewhat more compact design is thus possible.
- a valve is preferably arranged between the first gas area and the first drying area, which valve prevents the penetration of water into the first drying area.
- the first gas area and the first flood area are separated from one another by a movable, liquid-tight layer.
- a movable, liquid-tight layer for example a film, can prevent water from getting into the first gas area. This can also prevent gas from the first gas region from being released into the environment by the first pump.
- the first pump is selected from the group consisting of diaphragm pumps, plunger pumps and rotary vane pumps.
- the first pump is preferably a plunger pump.
- the buoyancy modification module has a second pump, the first pump and the second pump being connected in parallel.
- the first pump and the second pump particularly preferably have a common drive.
- the buoyancy modification module more preferably has a third pump, the first pump, the second pump and the third pump being connected in parallel.
- the first pump, the second pump and the third pump particularly preferably have a common drive.
- the buoyancy modification module has the external dimensions 2991 mm by 2438 mm by 2438 mm.
- the invention relates to a modular underwater vehicle.
- the modular underwater vehicle consists of at least three modules. At least one module is a first buoyancy modification module according to the invention.
- the modules have a basic shape which corresponds to a straight prism with a regular square as a base.
- the modules have a cuboid basic shape, a cuboid being a straight prism with a rectangle as the base area.
- This enables an optimal combination of the modules, both in terms of stability and space utilization.
- Not all modules have to have an identical shape.
- all modules have the same footprint so that they can easily be arranged one behind the other in a row.
- the length can differ between the modules.
- modules can have different base areas, for example and in particular a module can have a base area twice as large as another module, whereby this module can be combined with two further modules arranged next to one another.
- the foremost and rearmost modules have a shape that differs significantly from this in order to design the bow and the stern of the underwater vehicle in a streamlined manner. In each case, only compatibility with the base area of the next adjacent module is necessary.
- the first buoyancy modification module is mechanically connected to all adjacent modules. Furthermore, the first buoyancy modification module has an electrical connection with at least one adjacent module. The first buoyancy modification module preferably has a data connection with at least one adjacent module.
- Underwater vehicle on at least a first payload module Underwater vehicle on at least a first payload module.
- the first lift modification module and the first payload module are preferably adjacent. This is advantageous because the first payload module can change the mass of the modular underwater vehicle when a payload is deposited or picked up. The closer the first buoyancy modification module is, the smaller the change in the trim of the modular underwater vehicle.
- Underwater vehicle has a second buoyancy modification module, the first buoyancy modification module being adjacent to the first payload module on the bow side and the second buoyancy modification module being adjacent to the first payload module on the stern side.
- This symmetrical arrangement allows the trim to be kept particularly stable.
- buoyancy modification module according to the invention is explained in more detail below with reference to the exemplary embodiments shown in the drawings.
- Fig. 1 first not flooded buoyancy modification module
- a first buoyancy modification module 10 is shown in the non-flooded state and in FIG. 2 in the flooded state.
- the buoyancy modification module 10 has a Frame 20 and a first pressure body 30 connected to frame 20.
- the interior of first pressure body 30 is divided into two areas.
- the left area is divided into a first flooding area 50, which is provided for flooding with water, and a first gas area 60, in which a gas, in particular air or nitrogen, is located.
- a second buoyancy modification module 10 which additionally has two second gas areas 70, which are connected to the first gas area 60.
- the second gas areas 70 are preferably designed in the form of commercially available pressurized gas cylinders. The advantage is that these can be arranged in addition to the usually cylindrical first pressure body 30, making good use of the space in the frame 30. Furthermore, these are commercially available and therefore comparatively inexpensive components.
- the third buoyancy modification module 10 shown in FIG. 4 additionally has a gas pump 80, via which gas can be conveyed from the first gas area 60 into the second gas area 70 and back.
- the modular underwater vehicle 100 has a first payload module 110.
- a lift modification module 10 is arranged in front of and behind the payload module 110.
- the modular underwater vehicle 100 also has a bow module 120 which, for example, can have sonar and control electronics.
- An energy module 130 is arranged at the rear. This can have an accumulator, a fuel cell and / or a diesel engine that is independent of the outside air. All other modules are supplied with energy by the energy module 130.
- the modular underwater vehicle 100 also has a stern module 140, which has, for example, the traction motor and a propeller as well as the rudders. Reference number
