A water-bearing The conduit is mounted in a horizontal position along the bow and the conduit comprises a series of Slots or holes through which pressurized water can flow to the outside. The line is aligned so that it comes to rest under the surface of the water. A baffle is hinged in a horizontal position along the bow and around a horizontal axis pivotable. The pressurized water is forced out of the holes to create a wave or a cable cause which is pushed over the top of the guide plate. The size of the wave depends on the pressure generated by the pump, the size of the openings and the depth to which the Line is below the surface of the water. the Shaft is set at such a sufficient height that one carrying the oil or debris Layer of water goes over the top of the baffle plate.

When the watercraft is moved forward, the water wave passes over the top of the guide plate into the receiving space. When the water layer and the oil are moved over the guide plate, the mass of oil on the water surface is caused to move slightly over the upper edge of the guide plate into the receiving space. The oil can then be removed from the holding or hold by any of a variety of known methods.

Detailed description

With reference to the drawings and initially to FIG. 1, according to one embodiment, the device according to the invention on a watercraft 11 is in the form a boat with two pontoons 12 and 13 attached. The pontoon construction enables e, s ,, that the water- ' vehicle has a relatively wide rectangular bow section and a relatively flat hull

has. Suitable motors 15 can be attached to the stern of the watercraft 11 for propulsion. One deck 16 is suitably positioned over the central portion of the watercraft. A conveyor 18 extends at an upward angle from bow to stern. Part of the middle part of deck 16 is cut out at 17 with adaptation to the conveyor 18. The rear end of the conveyor 18 extends vertically above deck 16 such that any carried up along the conveyor Materials then fall onto the deck or into a container positioned on the deck be able. The conveyor 18 is a construction in the manner of an open sieve 19 for liquid Allow (water) to flow through and any debris such as weeds or plants that have been carried up on the conveyor, to hold back or prop up, as will be explained. The conveyor 18 also has drivers 21 to to prevent any debris from sliding back down the conveyor. A suitable motro and Gear drive assembly 22 drives the conveyor in the orientation of FIG. 1 in a clockwise direction.

FIGS. 2 and 3 show a pressure line arrangement 40, which includes a pressure line 24, a baffle 27 and a pivoting safety platform 38 which will now be described shall be. The line 24, which is made, for example, of metal or a solid plastic, extends horizontally along the bow of the watercraft and is used to transport pressurized water. Instead of pressurized water, it can be one under pressure standing, flocculated liquid and gas mixture can be used to give the floating material a to convey additional buoyancy.

The pressure line 24 has openings 26, e.g., slots, holes or nozzle cutouts, formed therein or attached to it. A spray, flow or jet effect forms when Pressurized water from a suitable pump, not shown, through two input lines 47 and 47A, the are each connected to opposite ends of the line 24 is conducted. By the feed of pressurized water to both ends of the conduit 24 becomes a relatively smooth and predictable uniform Preserve the amount of spray or jet effect. It has been found that when water is in only one end the pressure line 24 is pumped, an undesirably uneven spray, flow or jet effect is obtained, the spray at the input end of the line 24 has a low amplitude and on the other The end has an increasingly higher amplitude.

Suitable valves, not shown, for lines 47 and 47A may be provided to accommodate the Lines 47 and 47A directed water to the pressure line 24 and adjust the water pressure and thereby to control the height of the wave 50 caused by the jet action of the pressure line 24. At the Prior art embodiment, such as her in the above-mentioned patent, the angle of the guide plate 27 as well as the location of the Pressure line 24 are mechanically controlled in order to adjust the part of the shaft 50 which is above the guide plate to get into the stowage space of the watercraft. With the present construction, the water pressure can easily be adjusted appropriately and very finely to allow the desired portion of the shaft 50 over the guide plate 27 can go away.

The foregoing pressure control is also so far from

Significance as the pump for emulsified oil Can be throttled to a slight jet effect or to achieve a light jet so that the emulsion is not broken and a lesser one ■ 6, 'Amount of the total water required to flow over the guide plate into the loading area, however, a relatively larger amount of oil can be recovered in a more satisfactory manner.

as will be explained, the line 24 is perpendicular movable and also over a selected angle rotatable to direct the spray, flow or jet effect in the desired direction and a shaft or to create jumble of selected size extending the length of the conduit 24 and from the water surface rises upwards at a desired distance.

Refer now to Figures 5A and 5B to explain an important aspect of the present invention taken.

It should first be noted that the theory of operation and why the present inventive device \ such a significant improvement over the; Prior art achieved is not fully understood.

The most understandable explanation is as follows:

Assume that the oil recovery work is in progress. The kinetic energy of the through the slots the pressure water exiting the line 24 is the available releasing force or energy, to do this work. In the prior art construction according to FIG. 5B this power or energy visibly shared in order to access the

· * ■ Water above and below and behind the pipe 24 to act. Accordingly, with the construction shown in Fig. 5B, the oil becomes on the water surface and some amount of the "desired" water (i.e.

of the water below and behind or after the pipe 24) under and around the line through the passage 49 and over the 'transverse wall 4 5 into the storage space of the Moving the watercraft. The term "unwanted" water is used to refer to the water which is not to be treated or subjected to the procedure. It has been found that this becomes a Decreasing the effectiveness of the establishment leads.

Fig. 5A shows the present device according to the invention, with the line 24 in a manner similar to is positioned in Figure 5B. It is important, however, that in FIG. 5A the line 24 is in the vicinity of the Top of the transverse wall 4 5 is arranged such that the "undesirable" water flow below and behind the Line 24 is blocked or locked out. Accordingly, only the "desired" water from above and in front of the Line 24 causes the line 24 to flow.

In a particular oil recovery operation, the prior art design shown in Figure 5B had a production rate of approximately 7.95 m / h of light crude oil. When later reclaimed at the same location, the recovered oil was No. 5 high viscosity oil. The known construction according to FIG. 5B was used and the production rate decreased to about 60% to 3,339 m / h (21 bb / hr). In contrast, with the construction according to the invention, a production of 10.335 m / i \ (65 bbl / hr) was achieved with the viscous No. 5 oil compared to 3.339 m / h. In other working conditions, the

* Construction according to the invention has a production rate of 28.62 m ³ / h (180 bbl / hr) in contrast to 7.95 m ³ / h (50 bbl / hr) with the construction according to the prior art. It appears that the construction according to the invention enables all of the water required to fill the void (caused by the jet action or the flow of the conduit 24) to come from the surface water which is necessary to carry the oil to the watercraft 11 to move, see point A in Fig. 5A and Fig. 5B for comparison. Obviously, the water that is withdrawn below the line 24 in the edge construction according to FIG. 5 causes a return of the water movement at the surface.

'- ■■ ^: ' ■: '■■■ ■ :

It seems that the increased water speed creates an empty space due to the radiation effect! (as in point A), which must be filled out. At the In the prior art, the water can be seen to come from the bottom, sides and back of the pipe 24 to fill the void; and the line in Fig. 5B acts to restrict surface water, thereby drawing more water from the bottom, sides and back of the pipe can. In contrast, the inventive Construction that this empty space (at point A) exclusively through the desired or surface water is filled.

In the known construction it is obvious there is insufficient movement of the surface water, to overcome the surface tension of the oil; and it can be seen that the water takes the path of the least resistance, so that the water is drawn off below the pressure line. It therefore appears that all energy in the construction according to the invention

* is used to generate the flow of surface water to develop above the pressure line 24 and thereby overcome the surface tension and the oil to To move the watercraft.

Another important advantage of the invention Construction is that it works satisfactorily to remove oil and debris in clogged areas regain under docks and piers and in backwaters where the forward movement of the associated Watercraft is restricted. That is, the forward movement is not necessary for a satisfactory Operation of the construction according to the invention.

A rigid guide plate 27 made, for example, of metal or a suitable rigid plastic, extends along conduit 24 and is constructed to fit around pressure conduit 24 and allows plate 27 to rotate about the conduit, see also Fig. 3A. The leading edge of the guide plate 27 is positioned near the line 24 to ensure that only the "desired" water is over the Guide plate 27 is moved. In one embodiment the invention, the front portion 28 of the guide plate 27 is designed as a semicircle, which around the conduit 24 fits around and with its rear portion 31 extending upward at an angle, the desired amount of water and the desired size of the over the upper edge 31 (a) of the guide plate 27 to be able to choose flowing wave.

The baffle 27 is designed to direct the flow or spray of water from the pressure line 24 does not bother. It should be noted that in Fig.

3A shows the guide plate 27 and the line 24 in one

. mutual facility are shown; optionally can a sealing material can be used to make an intermediate seal. .

S The guide plate 27 can be moved from an angular position to a second angular position either manually - as indicated in FIG. 2 - or hydraulically, as in FIG. 4 indicated to be moved. As Fig. 2 shows, the plate can after reaching the exact angular position of the Guide plate 27 can be locked in position, e.g. by a bolt or rod 33 extending into Holes 34 which are formed in the side walls 36 of the pressure line assembly 40 extends. The size of the through the operation of the pressure line 24 in combination with the correct positioning of the guide plate 27 formed wave therefore allows control of the movement of the floating material in the direction of the Guide plate 27 and across this.

A pivotable catch platform 38 extends over the Length of the line 24. The pivotable safety platform 38 can pivot on the edge 28 of the guide plate 27 and act as a retainer to prevent the flow of material under conduit 24 to limit. In addition, the swiveling catch platform 38, which is pivotable about an axis which is essentially the longitudinal axis of the conduit 24, in a position similar to that of the guide plate 27 locked, see Figs. 2 and 4, thereby directing the movement of the floating material upward towards the pressure line 24.

As clearly shown in Figs. 2 and 4, the guide plate 27 and the pivotable safety platform 38 can be positioned in different angular positions be to the flexibility of the design too

raise.

The pressure line arrangement 40, which, as mentioned above, the pressure line 24, the guide plate 27 and the pivoting safety platform 38 includes, is in their Brought operating position on the bow of the watercraft 11, see Fig. 1. The watercraft 11 encloses spaced apart, vertically extending, C-shaped rails 41 their bow, see also Fig. 3. Shafts 42 extend outwardly from the walls 36 of the assembly 40, and rollers 43 are attached to the free ends of the shafts 42. The respective corresponding roles 43 run in the rails 41, see FIG. 3. Hooks 44 are suitably positioned on the upper edges of the walls 36 attached. The hooks 44 are connected, for example, by suitable chains and sprocket arrangements as indicated at 46, is detected to lower the assembly 40 into position.

When the arrangement 4 0 is to be brought into its operating position, it will be in such a position lowered and supported there that the pressure line 24 is slightly below the water surface. The water or a liquid and gaseous mixture flowing under pressure through the pipe is pumped, is pushed through the openings to form the shaft or cable 50, see FIG. 4. The size of the wave is determined by adjusting the depth of the line 24 below the surface of the water, des Water pressure, the angle of rotation of the line 24 and the angle of the guide plate 27 and the pivotable Falling platform 38 discontinued. It should, of course, be noted that the speed of travel is through the water moving watercraft 11 also exerts a main effect on the wave to be developed. All in all
