Definitions

  • the invention relates to a ship propulsion system according to the preamble of claim 1.
  • Such ship propulsion systems have variable pitch propellers. which are used in particular in ships to select the propulsion regardless of the speed of the marine engine can. Variable pitch propellers are therefore particularly advantageous when the feed often changes.
  • variable pitch propellers can indeed be made very robust, already minor defects, such as leaks, but cause that they must be repaired immediately to prevent escaping hydraulic fluid must be replaced.
  • the invention has for its object to provide a particularly safe to operate marine propulsion.
  • the invention solves the problem by a variable pitch propeller with the features of claim 1.
  • An advantage of such a marine propulsion system is that it is fault-tolerant. Even if the hydraulic adjusting device shows a leak, it is usually not necessary to repair the adjusting device immediately. The reason is that a hydrophilic hydraulic fluid such as water or glycerin is readily available everywhere with little effort. A loss of hydraulic fluid can be easily compensated.
  • Another advantage is that the formation of steam and cavitation bubbles is largely excluded. Even at high temperatures, for example in the engine room, in which a pressure water distributor can be arranged to supply the variable pitch with hydraulic fluid, and also an increased contribution of heat energy in the variable pitch by frequent operation, it is ensured that no steam and cavitation bubbles can occur. Cavitation quickly leads to heavy wear and occurs when the steam pressure is locally and temporarily undercut.
  • the hydraulic adjusting device is understood to mean, in particular, that device by means of which the setting angle, which is decisive for the pitch of the propeller blade, can be adjusted.
  • the adjusting device preferably comprises a pressurized water source for discharging pressurized water.
  • the pressure of the hydraulic fluid which is built up by the pressurized water source is at least 5 bar, in particular at least 50 bar.
  • a hydrophilic hydraulic fluid is meant, in particular, a fluid which is miscible with water in any ratio.
  • the fluid comprises at least 70% by weight of water and alcohols.
  • the hydraulic fluid for fish is nontoxic up to a concentration of 0.1% by weight. This is understood in particular to mean that the zero effect concentration, ie the concentration at which no fish dies within 24 hours, is at least 0.1% by weight.
  • the hydraulic fluid is biodegradable. This is understood to mean, in particular, that it complies with the modified OECD Screening Test OECD 301 E.
  • the hydraulic fluid is at least 80% by weight water.
  • the water it is possible for the water to contain additives, for example corrosion inhibitors and / or an antifreeze.
  • additives for example corrosion inhibitors and / or an antifreeze.
  • the higher the water content the sooner leakage into the environment can be tolerated.
  • the hydraulic fluid contains no substances toxic to aquatic organisms. By this is meant in particular that an introduction hydraulic fluid into the water is possible without endangering the aquatic life. It is particularly favorable if the hydraulic fluid contains at most 2.5 percent by weight, in particular at most 1 percent by weight, of mineral oil. If hydraulic fluid escapes, mineral oil components cause a clearly visible oil film to form on the affected water surface, which is undesirable from an environmental point of view. If the hydraulic fluid contains a mineral oil or only very small amounts thereof, escaping hydraulic fluid can not contaminate the surrounding water.
  • a list of aquatic organisms of non-toxic substances can be found, for example, in the General Administrative Order to the Water Resources Act on the classification of substances hazardous to water in water hazard classes, Federal Gazette, Vol. 51, Number 98a, ISSN 0720-6100.
  • the at least one propeller blade is at least also mounted on the hub by means of a solid lubricant element and / or self-lubricating on the hub. This prevents a release of petroleum products into the water.
  • the hydraulic adjusting device comprises a piston coupled to the at least one propeller blade, the propeller blade actuable by pressurizing the piston with hydraulic fluid, and a transfer device for converting longitudinal movement of the piston into rotational movement of the at least one propeller blade is designed self-lubricating.
  • the transfer device comprises no lubricant, in particular no mineral oil-containing lubricant. It is particularly favorable if all components of the variable pitch propeller which are at the same axial height as the hub are free of lubricants based on mineral oil. In particular, these components are self-lubricating.
  • the axial height refers to the axis of rotation of the hub.
  • FIG. 1 schematically shows a cross section through a ship 10, which has a ship propulsion 12 according to the invention, which comprises a drive motor 14 in the form of a marine diesel and a variable pitch propeller 16.
  • the variable pitch propeller 16 has a hub 18 and a first propeller blade 20.1, a second propeller blade 20.2 and other propeller blades, the FIG. 1 are not shown.
  • the propeller blades 20.1, 20.2 are variable by means of a hydraulic adjusting device 22 in pitch.
  • the slope is given by a setting angle ⁇ .
  • FIG. 1 also shows a rudder system 24 of the ship 10.
  • the adjusting device 22 has a pressurized water distributor 26, which is part of a pressurized water supply device 27 and is connected to a schematically illustrated pressurized water source 28 so that provided by the pressurized water source 28 and pressurized hydraulic fluid 29 in the form of water to a piston 30 in the Hub of the variable pitch propeller 16 can be delivered.
  • the operation of this piston is in the FIGS. 2a and 2b explained in more detail.
  • FIG. 2a shows a variable pitch propeller 16, in which the piston 30 is arranged in a hydraulic cylinder 32 within the hub 18. If the pressurized water distributor 26 acts on a first partial volume 34 of the hydraulic cylinder 32, the setting angle ⁇ increases. If the pressurized water distributor 26 acts on a second partial volume 36, the setting angle ⁇ decreases.
  • the piston 30 is made of corrosion resistant material, such as bronze and / or corrosion resistant steel.
  • FIG. 2b shows an alternative embodiment of a variable pitch propeller 16, in which the hydraulic cylinder 32 and thus the piston 30 are arranged outside the hub 18.
  • the piston 30 is connected to a piston rod 38 which passes through a shaft 40 and actuates the propeller blades 20.
  • the marine propulsion system 12 comprises a cooler 42, by means of which the hydraulic fluid 29 can be cooled.
  • the radiator 42 in the present embodiment is a heat exchanger connected to the cooling water circuit of the vessel 10.
  • the temperature T of the hydraulic fluid is continuously determined. If the temperature exceeds 60 ° C, a warning signal is output, for example in the form of an electrical signal that encodes the fact that the temperature is too high. Alternatively, the warning signal causes the radiator 42 to more strongly cool the hydraulic fluid. This prevents heating to a temperature significantly above 60 ° C and avoids vapor bubbles.
  • FIG. 3 shows the structure of the hub 18 in cross section with more details.
  • a transfer device 41 by means of which the longitudinal movement of the piston 30 is converted into the rotational movement of the propeller blades 20.
  • the hydraulic fluid 29 in the present embodiment has the following composition: 15% by weight of ethylene glycol as antifreeze and 85% by weight of water.
  • the water may be, for example, drinking water or seawater.
