Description

[Detailed description of the invention] The present invention is a jet device for steering or propulsion and steering of a ship, and consists of a pump that sucks water from the bottom of the ship and discharges it in a selectable direction, and a jet device that selectively directs water flow at the ship wall. The present invention relates to a type having a passage system for ejecting water and a motor fixed to the passage system for driving the pump.

Jet devices of this type with propeller pumps or centrifugal pumps driven by internal combustion engines or electric motors are known and are used as side thrusters, especially stern side thrusters or propulsion and steering devices.

The components of this jet system, namely the pump, its casing, deflection device, passageway, motor, motor foundation and other general auxiliary equipment, have traditionally been integrated into the ship individually, sometimes separately with the hull. It was welded. This is inconvenient for storing, assembling, and replacing such components.

It is therefore an object of the invention to improve a jet device of the type mentioned at the outset and to facilitate its storage, assembly and disassembly.

This problem is solved according to the invention in a jet device for steering or propulsion-steering a ship of the type mentioned at the outset, in which the motor is located in at least a portion of one passage, and the longitudinal axis of the motor is aligned with the longitudinal axis of said passage. the pump, the pump casing and at least the part of said passage forming the basis of the motor are arranged in a transportable unit, parallel to said passage and mounted by means of a supporting structure in such a way that said passage forms the basis of the motor; This was solved by configuring the .

By configuring the jet device as in the present invention, it is not only easy to stock, assemble, and disassemble the components constituting the jet device, but also the jet device can be easily repaired and replaced. In other words, since the jet device is a transportable unit, repairs and replacements of the components that make up the jet device are carried out by mooring the ship in a bay, removing the jet device as a unit from the ship, and then repairing and replacing the components that make up the jet device. The damaged component can then be repaired and replaced, transported to the unit and then to the bay, where it can be reinstalled on the ship. Therefore, the time required for repairs and replacements is extremely short, and the time that the ship must be moored in the bay is also extremely short.

Further, in a side thruster, particularly a side thruster for a stern, it is advantageous if the jet device is configured as described in claim 2 of the utility model registration. Further, in the propulsion and steering device, the jet device is constructed as shown in claim 3 of the utility model registration. In this case, it is common to provide four passages in four main directions. Of course, if the water stream is freely discharged backwards or if there is no need for a forward discharge of the water stream, the passage extending along one of said main directions can be omitted. In such a propulsion and steering device, all four passages or separate passages can be used as the basis for the motor. Thus, in side thrusters the motors are arranged at right angles to the longitudinal axis of the ship, whereas in propulsion and steering systems the motors can also be arranged longitudinally. A particularly advantageous configuration for the propulsion and steering device is described in claim 4 of the utility model registration.

The invention will now be explained with reference to the drawings: A propeller pump 1 (FIG. 1) is mounted in a casing 2 rotatably about a vertical axis. The propeller pump 1 sucks water from the bottom of the ship (West German Patent No. 2215344, US Patent No.
3903833 specification). Channels 3, 4 are connected to the casing on both sides. These passages 3, 4 are oriented towards the starboard and port sides of the vessel 5. The flow of water sucked in by the propeller pump is directed selectively into one passage by the shield 6. For this purpose, the shield 6 is pivotably mounted in the housing 2 about a horizontal axis 7 and is driven to pivot by a hydraulic motor 8 or another suitable drive. The propeller pump is driven by a motor 11 via an orthogonal transmission 9, for example a bevel gear transmission or a worm transmission or the like, and a cardan shaft 10. Although the motor 11 is an internal combustion engine in this embodiment, it may also be an electric motor. In this case, the lateral thrust by the water is controlled in that the shield 6 is only partially pivoted.

One of the passages, namely passage 4, is fixedly connected to the housing 2 and together with the spars 12 forms the basis of the motor. In this type, a propeller pump 1, its casing 2, the passage 4, a water flow deflection device (shield 6), its driving device, and a motor 1 are provided.
1 and torque transmission members (transmission device 9 and cardan shaft 1
0) constitutes a unit that can be stored, transported and assembled separately. By using the passage 4 as the basis for the motor, a structure with low weight is obtained.

FIG. 2 shows a jet device configured as a propulsion and steering device. A propeller pump 21, which may be a centrifugal pump, is arranged within the bend 22 so as to be rotatable about a vertical axis of rotation. The bend 22 itself is supported in the casing 23 so as to be pivotable about the same axis of rotation. bend 2
2 is constructed in an L-shape, and water sucked in by its vertical part is discharged from the horizontal part in a selected direction. Said pivoting movement is provided by a motor 24. A motor 25 is provided to rotate the propeller pump. This motor 25
The torque is transferred to the Cardan shaft 26 and the orthogonal transmission 2.
7 to the propeller pump. The discharged water is directed in four directions. This is an opening 28 that opens to the outside or is connected to a passageway;
29 and another opening facing opening 29;
This is done via a channel 30 which together with a beam 31 forms the basis of the motor.

All parts described constitute components that can be transported and assembled as a unit.

Note that any type of connecting member for the passageway and the opening to the ship can be used, so it is not shown in the drawings. Kuratsuchi,
Auxiliary equipment such as coolers, batteries, switching and control boxes, etc. are likewise not shown, but these can optionally belong to the unit according to the invention.
