5926 / Ol / Bu / gn - January 19 - January 5, 1972

Anchoring of the device in front of a bridge warehouse (pillar) to collect all floating debris or the like including oil brought downstream of a river by its flow.

The embodiment includes a tank 10 which is generally very similar to that of the embodiments of Figures 1 and 2; it has opposite side walls 11, a rear wall 12 and a front wall 13 and a floating deck lh » Since the tank is not used to move (drive) through the water, there is no need here, front and rear walls designed so that the buoyancy of the tank (reduction in flow resistance) is improved, and the tank can be made deeper in relation to its length. Since the tank is not intended to be manned, the cabin 15 and the rings 15 * ν can be dispensed with. The motor for operating the paddle wheel or the like 22 and the tine shaft 30 is still mounted on the deck and provided with a suitable housing.For the sake of clarity, this motor and the necessary gearbox for driving the paddle wheel and the shaft 30 are shown in FIG. 3 -5 not shown. In this embodiment, the trough 27 and its movable lip 28 are not required because the tank is hardly exposed to sudden changes in the water level.

As in the embodiment according to FIG. 2, here too the paddle wheel 22 is as far behind as possible

set forward so that the inlet passage 17 is relatively short. The paddle wheel is here actually mounted in front of the floating dock 14, with the paddle wheel housing 26 extending forward to form a foredeck 33, under which the inlet passage 17 is arranged, and the forward one end d & s foredeck is provided with slots 32, work in which or through which the tines 29th For the sake of clarity, only one set of four prongs is shown in FIG. 4, and the prongs are omitted from FIG. In order to increase the lift, the deck 14 is widened and extends further to both sides of the foredeck 33 and 34 and 35, as shown in FIGS. 4 and 5.

At the front end of the tank 10 is provided with a V-shaped guide means (inlet mouth) which allows the oil and other floating material to flow (directed) into the inlet port 16. This guide means (which is shown only in Fig. 5 for the sake of clarity) consists of two (cantilever) arms 36 and 371 which be carried (supported) on the water by swimmers (not shown), being by each of the two Arms hanging down an apron with its lower end dipping below the water level.

At the rear end of the deck 14, a slot 38 is provided which communicates with the interior of the tank (FIGS. 4 and 4) 5) communicates. Through this slot, very light floating debris collected by the device, such as Long pieces of wood, bottles, tins, tins, which be piled or heaped up inside the container, overflowing or "poured over" into one floating wire mesh cage (not shown) in the river

The rear wall 12 of the tank is expediently shaped so as shown in Figure 3 at 39, so that they are such waste up through the slot 38 in the cage brings or leads.

If desired, the tank can be provided with a driven endless conveyor belt, which moves on the deck from front to rear, and on which material brought up by the prongs 29 is deposited and to the rear, i.e. to the rear part of the tank, and from there is brought into the wire cage. This relieves the weight of any such material on the tank and prevents it from sinking too deeply into the water.

If desired, the tank can be provided with additional ballast tanks, which make it possible to that the tank in the water is raised above the level at which the floating dock (alone) allows it to swim brings. This may be desirable when very thin oil is to be collected and by suction Surface tension plays a major role in the topmost water layer.

The embodiment according to FIG. 6 is also intended for stationary use, for example

to lay against a harbor wall to collect oil that has hit the wall by wind or currents is driven.

In this embodiment, the tank has a semicircular contour in plan view, the flat side (outer wall) 39 being intended to rest against the harbor wall. The curved side kO of the tank is provided with two oil collecting systems kl and k2, of which, such as ± _n ^ has each an inlet port, an inlet passage, a weir, a wing or paddle wheel and prongs described en preceding embodiments. The deck Ik is provided with a central opening 43 which is surrounded by a wire mesh fence, not shown. This permits bottles, tin cans, wood and the like aufschwimmendes waste material rises through the opening, without being washed over the deck ·

The deck is provided with hangings kk , to which ropes can be connected, which can haul the tank from one place to the other. This is necessary because a change in wind or tide can change the direction in which an oil spill or mud or the like is drifting, thus requiring that the location of the tank be changed.

While the device according to the invention is particularly suitable for collecting oil from the surface (the water level) of water, it should be emphasized that other floating goods, such as marine

Outward movement of the flap is prevented by boards or similar straps attached to both sides of the front part of the tank. When the tank moves through the water, the water pressure (upstream pressure) will easily (slightly or more) the flap. open and so allow water to enter through the resulting opening, and the water leaves the tank again through its bottom. This arrangement is, so it has been found suitable to reduce the water resistance at the forward movement of the tank significantly "The arrangement can also be used with advantage, even if the tank is partially freed from the water, such as additional while driving when using (then more or less empty) buoyancy tanks on each side of the tank, as already described above .
