Definitions
- the present invention relates to a device for remov ⁇ ing impurities from water, more precisely a device which comprises a substantially V-shaped floating cassette hav ⁇ ing a rear portion with projecting legs, and a collecting means.
- SE 416,659 discloses techniques for removing and collecting impurities, such as oil, oil products, dead animals, undesirable surface vegetation, and all sorts of rubbish, from the sea, lakes, rivers, streams, swimming pools, and other bodies of water.
- impurities such as oil, oil products, dead animals, undesirable surface vegetation, and all sorts of rubbish
- the device described in the SE patent has several drawbacks.
- its rear portion is made up of a number of interconnected, tubular netting elements.
- this device is only able to operate at a fixed depth of water, which is most unsatisfactory, since the impurities are, of course, to be found at all levels.
- this prior-art device can only be used with a rather wide-meshed net, or the flow through the netting elements, as well as the compacting of the impurities therein, will become poor. If so, only lumps of oil and other such fairly solid impurities can be collected.
- the object of the present invention is to completely eliminate, or considerably reduce, the drawbacks of prior- art techniques.
- the device according to the invention is essen ⁇ tially characterised by a tube which is connected to said rear portion and opens at a hole therein and which is enclosed by the collecting means, and a vertically adjust ⁇ able plate which is pivotably connected to the cassette for collecting the impurities at an optional depth of water.
- Fig. 1 is a schematic side view showing a device according to the invention
- Fig. 2 is a top view showing the device of Fig. 1
- Fig. 3 is a view showing a vertically adjustable bottom plate according to the invention.
- Fig. 4 is a broken-away side view showing a rear por- tion of the device.
- Figs 1 and 2 illustrate a preferred embodiment of the invention, which comprises an adjustable, floating cassette 1 having a rear portion 2 tapering conically into a tube 4.
- Front legs or pontoons 3a, 3b and rear legs or pontoons 13a, 13b are connected to the rear portion 2.
- the pontoons 3a, 3b, 13a, 13b are articulated to the rear portion 2 to make the device flexible when there is a wave motion.
- a vertically adjustable bottom plate or 'ski board' 6, which is pivotably connected to the rear portion 2 by a shaft 7, is provided between the front pontoons 3a, 3b.
- the bottom plate 6 is perforated to a certain extent in order to reduce the water resistance.
- a fibre cloth or a fine-meshed net is connected to the tube 4 which it encloses along part of its length.
- the fibre cloth 8 is maintained on the tube 4 by a clamp or brake means 14, e.g. a tightening strap permitting the fibre cloth 8 to be fed out at an optional rate.
- a valve 9 is provided in the tube 4.
- a feeder means 15 such as a propeller, flushing nozzles and a mechanical screw for pushing the impurity towards and into the fibre cloth 8 and compacting it.
- the front pontoons 3a, 3b may be equipped with feeder means, e.g. flushing nozzles 16.
- the cassettes 1 mounted on pontoons can be adjusted to different depths of water by means of the vertically adjustable bottom plate 6, as shown in more detail in Fig. 3.
- a front portion of the bottom plate 6 is perforated.
- the bottom plate 6 is equipped with side walls 10 having lifting eyes 11 connected to the front pontoons 3a, 3b by wires, ropes, chains or the like, for adjusting the draugh .
- the feeder means 15 is arranged in the rear portion 2 and is, in this embodiment, a propeller 15.
- This propeller is disposed just in front of the opening of the tube 4, and its driving device 17 is attached to an upper plate 18 of the rear portion 2.
- the device 1 operates as follows. A device 1 (or several such juxtapos ⁇ ed devices) is winched or towed across the area of water from which an impurity is to be removed.
- the bottom plate 6 is set at a suitable depth, depending on the vertical spreading of the impurity.
- the impurity is transported by the movement of the device 1, optionally with the aid of water (jets) or compressed air supplied to the cassette 1 through the flushing nozzles 16. Then, the impurity is conducted into the tube 4 and the fibre cloth 8 by the propeller 15.
- the fibre cloth 8 is fed out as it is being filled with the impurity.
- the valve 9 is temporarily closed, whereupon the fibre cloth is drawn together or tied up, or riveted or the like, just behind the tube 4, and is cut off by a suitable device (not shown). This results in suitable, sausage-shaped elements having a weight of about one to a few dozen tons, which are taken on board a boat, a barge or the like.
- the rear pontoons 13a, 13b may be dispensed with, the front pontoons 3a, 3b may at least partly consist of booms that can be extended to an optional length, and the feeder means 15 may be a screw without a shaft portion provided in the tube 4.
