摘要:
The invention relates to a regulator for compensating level variations of water surface in conjunction with a water intake opening. The regulator includes a shutter member (11) to be moved vertically, which can be moved between the open position and the closed position, whereby while in the open position, the shutter member (11) opens a flow path to enable stream of water, and while in the closed position, the shutter member closes the flow path. According to the invention, the regulator includes a float (4) connected to the shutter member (11), which has been arranged before the shutter member (11) in the flow direction and dimensioned to float in a given depth, and which as the water level (13) sinks, moves the shutter member (11) toward the closed position.

Provided is a device for collecting oil contained in ice. The device includes a lifting device fixed for example to a vessel, a cage of separation adapted to be lowered into the water between the ice blocks by means of the lifting device and formed by a box which lets water and oil but substantially no ice, and an oil collector for collecting the oil on the water surface in the space defined by the separation of cage.
摘要:
The object of the invention is a purification device and a corresponding method for removing impurities from the surface of the water. The purification device has a suction device (2) with a suction canal (1). A vertical sheath forming a suction canal (1) according to the invention has a vertically narrow and horizontally wide suction slit (3), which is above the surface (4) of the water to be processed. Further, below the suction slit (3), the sheath has an underwater control surface (5) uniformly rising from the horizontal upwards towards the suction slit, along which control surface the air flow directed into the suction slit (3) pulls the impurities on the surface of the water (4) along with it.
