SE452485B - OIL COLLECTION DEVICE FOR PURIFYING OIL POLLUTATED WATER - Google Patents

Description

Which has the features stated in the characterizing part of claim 1. By means of the specified adjustable drive device, the tugs become easy to maneuver and the inflexible coupling of the boats with the barge means that the tendency of the boats to collapse is prevented.

The invention has significant advantages over the prior art. Acquisition costs are low as tugs already exist and it is only a matter of acquiring the oil capture barge. The unutilized capital is very small as this only relates to the barge because the tugs can be used in the usual way. The effect is large at high working speed and in addition the invention offers many combination possibilities. Maintenance costs are low as the oil capture barge is virtually maintenance-free. The degree of readiness is high because the tugs are constantly in use or available. Reliability is great because all sensitive parts and operation occur on the constantly waiting tugs.

No additional staff is required.

The invention will be described in more detail below with reference to the accompanying drawings, which show exemplary embodiments. Figures 1 and 1a show a tugboat trailer according to the invention during transport to the place of use. Fig. 2 shows the tugboat trailer according to Figs. 1 and 1a in use and Fig. 3 shows a further combination possibility according to the invention.

In Fig. 1, an oil catchment barge is denoted by 1, which at the height of the waterline has an oil or similar receiving opening 2. the opening leads to an inner collecting container. Such openings and collection containers and other devices for collecting and collecting oil are known and will therefore not be described in more detail. During transport to the place of use, the barge is pulled by a first tugboat 3 while the second tugboat 4 independently moves to the place of use. The tugs are provided with a pair of rudder propellers 5, 6, which are arranged before the rally center of gravity 7. The two rudder propellers are, for example, in parallel with each other during transport to the place of use and are swung out of this position, so that the tugboat is turned during maneuvering. In use, the two tugboats 3 and 4 (Fig. 2) are connected to each other by means of the oil catchment barge 1 over coupling element 17, so that they form an open angle in the direction of movement 8 of the towing trailer.

The oil catchment barge lies with its axis in the bisector of this angle. the opening is turned in the direction of travel and can in this way absorb oil 18. The rudder propellers are set in contrast to the rest position shown in Fig. 1 in such a way relative to each other that their traction direction forms a right angle with the connecting line 9, 10 between the lateral center of gravity 7 and their actual pivot axis and more specifically in such a way that in this rest position (or starting position) - at the same propeller force - they exert the same or opposite torques about the lateral center of gravity. If they are pivoted from this rest position or starting position in the same direction of rotation, the tugs perform a pivoting movement without turning (this device is described in detail in DE-OS 27 18 831).

If the rudder propeller is turned in a suitable position, the pushing forces 11, 12 and 14, 15 of the rudder propellers lead to a resultant 15, 16, which extends parallel to the direction of travel 8. How to find this suitable position is within the control of the helmsman's ability to maneuver the boat.

The tugboats arranged in the manner described relative to the barge force the oil intended for capture into the opening of the barge. Occurring gaps between tugs and barges can be covered.

The invention enables a number of combination possibilities. In Fig. 3, for example, two oil catchment barges are arranged next to each other. These barges are towed by a pair of tugs 22, 23 and 24, 25 on each side. The tugboats arranged one after the other 454 452 485 4 are connected to each other in such a way that the lateral displacement of both pairs is transmitted to the barges. The coupling means 27, 28 between the paired tugs 22, 23 and 24, 25, respectively, do not cause any pivoting of the tugs in each pair relative to each other, as schematically indicated. Fig. 3 only illustrates the combination possibilities of the invention. As two barges and four tugs are available, for reasons of convenience, two units consisting of one barge and two tugs are usually assembled.

-If the arrangement of the tugboat propeller so requires, the tugboats can also be connected to the barge over the bow. They will then reverse, which, however, does not change the principle of the invention.

Claims (1)
