摘要:
Method for removing alluvial deposits from the bottom of a watery area, whereby the layer of alluvial deposits (6) situated on the bottom (13) is carried to a place of discharge (16), whereby the removal of the alluvial deposits (6) takes place under a diving bell (2) placed on or in the vicinity of the water bottom (13) and in which an atmospheric pressure is generated which is practically equal to or larger than the pressure of the water column measured outside the diving bell (2) as of the lower edge (5) of the diving bell (2) up to the water line (17), and whereby the alluvial deposits (6) are sucked in in situ by a pump (14) and are carried to the place of discharge (16) via a tube (15). Device to be used with the method according to the invention.
摘要:
Device for cleaning a submerged surface (12) of a vessel (7) or similar, whereby the device (3) is provided with a cleaning module (2) with at least one rotating brush (11) which, upon the movement of the cleaning module (2), ensures that the cleaning module (2) is pushed or sucked against the aforementioned surface (12), characterised in that the device (3) is further provided with a launch platform (1) that can place the cleaning module (2) against the aforementioned surface (12) and which is connected thereto by means of a first cable (15) for the control of the cleaning module (2), whereby this launch platform (1) is provided with at least one camera (4) and a drive (8) to move the launch platform (1) underwater, whereby the launch platform (1) is connected to means (16) to bring the launch platform (1) to a desired location underwater, whereby the launch platform (1) is connected via a second cable (5) to a control unit (6) for controlling the launch platform (1) and the cleaning module (2).
摘要:
Device for generating hydroelectric energy making use of the current of a river (11), estuary or similar, and this device comprises a paddlewheel (2) that can freely turn in two directions around a shaft X-X′, and comprises at least one electricity generator set (4) whose drive shaft (8a) is coupled to the shaft (3) of the paddlewheel, whereby the device (1) is further provided with means to keep the paddlewheel (2) in place against the current, characterized in that the paddlewheel (2) is self-floating.
摘要:
Device for generating energy making use of the current of a river (2), with a self-floating paddlewheel (13) and an electric generator set (17) that is coupled to the paddlewheel (13), whereby the device (1) is provided with an immersed housing (3) with an open bottom (4) in which the paddlewheel (13) is rotatably affixed and whereby there is a unit (10) to control the flow of the river (2) at the level of the paddlewheel (13), whereby the speed of the generator set (17) is kept constant by controlling the water level (9) in the housing (3) by placing its internal space (7) under pressure and/or by controlling the aforementioned unit (10).

摘要:
The invention relates to a device for removing the growth on a ship's hull (2). This device comprises a cleaning element (3) and means for displacing this cleaning element over the hull (2), which means comprise at least one cable (4) which is arranged such that it passes underneath the keel of the hull (2) and to which the cleaning element (3) and means (5) for moving the cable (4) are connected. The cleaning element comprises at least one mat (3) comprising a flat base (13) consisting of an elastically deformable material, which at least at one side, is provided with a relief (14) of wear-and-tear-resistant, elastically deformable material. In the mat (3) at least one magnet (17) is provided.
