DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a cleaning-device combination for cleaning oil-contaminated shore water and shore area, the combination comprising at least one manually operated brush having an arm and a collecting container having as part of the container or separately a scraper or suchlike for removing from the brush the oil adhering to the brush and for directing the oil into the container.
For cleaning a shore area and shore water from oil spills it is known to use spades, brushes and other similar tools to which the oil adheres or by means of which the soil can more or less satisfactorily be skimmed from water surface, from stones and rocks on the shore, etc. When brushes are used it is natural that the brush must betweentimes be continually cleaned, for example by drawing or pressing it against the rim of the collecting container. All known devices are, however, in generral unsatisfactory with respect to their cleaning efficiency and their capacity, and also with respect to the capability of the collecting member itself to be cleaned rapidly. For this reason the object of the present invention is to provide a combination which is specifically suitable for the said purpose and in which the manual work can be made more effective and can be facilitated as much as possible.
In order to achieve this objective the cleaning-device combination according to the invention is characterized in that the brush comprises a substantially cylindrical bristled part and an arm secured to it centrally in the manner of an axle, and that the cleaning device for the bristled part, mounted in connection with the container, on the other hand comprises a mantle part which substantially corresponds to the outer shape of the bristled part, one end of the cleaning device being open for the pushing in of the brush and there being mounted inside it on a bearing a scraping device which pushes between the bristles of the bristled part, the scraper scraping oil from the bristles and directing the oil into the said container when the brush is being rotated in one direction or when the brush is being pulled out.
The device for cleaning the bristled part is preferably mounted above the collecting container in such a way that the open end of the mantle is directed obliquely upwards. The said open end may slightly widen conically in order to facilitate the pushing in of the bristled part.
The scraper is, in a manner known per se, preferably saw-blade-like and mounted on a bearing on one side of the mantle in such a manner that its teeth push between the bristles of the brush in the peripheral direction, obliquely inwards towards the core of the bristled part. In this case the teeth can be given the shape of a bird's beak so that, when the bristled part is rotated against the teeth, the teeth press inwards towards the core. At the mouth of the mantle part there may be a guide plate adjoining the scraper in such a manner that, when the bristled part is pushed in, this guide plate raises the scraper blade to the periphery of the bristles.
The combination according to the invention preferably comprises a collecting container to be shared by several users, i.e. several brushes, together with a cleaning device.
The invention and its other special characteristics and advantages are described below in greater detail in the form of an example and with reference to the accompanying drawings, in which:
FIG. 1 depicts a brush according to the invention, upon having been lifted from water,
FIG. 2 depicts a brush according to the invention being used in surface water of a shore area,
FIG. 3 depicts schematically a cross section of the cleaning device as seen from the end,
FIG. 4 depicts the cleaning device mounted on the collecting container, and
FIG. 5 depicts, partially in cross section, the same device as is shown in FIG. 4, but as seen from the side.
The brush belonging to the combination according to the invention is indicated in FIG. 1 by reference numeral 1. It comprises a substantially cylindrical bristled part 2 made of, for example, plastic,
