Definitions

  • the present invention relates to a device for oxygenating lower layers of standing water.
  • DE-U-296 07 656 for example, pipelines floating in water by means of buoyancy bodies are known, via which compressed air is released into the depth of the water.
  • DE-U-297 08 404 shows a housing standing under the water level with a cushion of gas mixture in the area of which circulated water is sprayed. A serpentine-like rise of air pumped in at the bottom of the water allows a device according to DE-U-298 11 813. Further devices with pumps for the introduction of air show DE-A-198 01 238 and DE-U-297 04 943.
  • the object of the present invention is to provide a device for the oxygenation of lower layers of standing water is simple in construction, requires as few supply lines as possible, intervenes minimally in the water, works as quietly as possible and can be used flexibly in many places.
  • a device for oxygenating lower layers of standing water consists of a pipe vertically inserted into a water, a shaft rotating in the pipe, a drive means for the shaft, at least one paddle stirrer fastened in the pipe to the shaft with at least two rising blades and a holding device for the pipe, the holding device holding the upper end of the pipe above the water level.
  • the paddle stirrers convey water from deeper water layers up through the pipe. The water comes out of the pipe and breaks over the edge of the pipe. This effect leads to an enrichment of the water with oxygen.
  • the path is modeled on nature, where this enrichment in flowing waters takes place through the refraction over shallows and banks.
  • the holding device is arranged on a firmly anchored device, sensors for detecting the height of the water level are present, as well as means for vertical adjustment of the pipe.
  • the holding device is arranged on a floating device and the tube is fixedly mounted on the holding device.
  • a balanced stabilizing stirrer is advantageously arranged at the lower end of the shaft.
  • at least two paddle stirrers arranged at a distance from one another, each with 4 rising blades, are attached to the shaft.
  • the drive means for the shaft preferably consist of an electric motor and an adjustable gear.
  • the transmission is advantageously infinitely variable in a range between 50 and 110 revolutions / minute.
  • the transmission has a control for automatically regulating the rotation and the control reacts to signals from a measuring instrument which measures the conveying speed of the water in the pipe.
  • the shaft is preferably mounted in a tapered roller bearing for absorbing the axial forces, and in one or ball bearings for compensating radial forces. It only needs to extend in an upper section of the tube.
  • the device according to the second embodiment of the invention is arranged, for example, on a frame connecting several floating bodies.
  • the floating bodies are advantageously floodable and can be emptied.
  • An illumination and / or a signal light is advantageously present.
  • the power supply takes place photovoltaically.
  • the electric motor is then preferably a direct current motor and there are means for storing electrical energy that is not required, these means delivering direct current when the photovoltaic supply is weakening.
  • FIG. 1 shows a schematic representation of a device 1 for oxygenating lower layers of standing water.
  • This consists of an elongated tube 2, for example with an inner diameter of 50 cm and a length of 20 m.
  • the tube 2 is preferably made of a weather-resistant plastic.
  • a rotating shaft 3 is arranged in the pipe, which is led out of the pipe 3 at the top and is flanged there to a bearing shaft 8 aligned with it.
  • the bearing shaft 8 is supported with roller and ball bearings in a bearing block 17 and is driven by a drive shaft 7, which in turn is driven by drive means which consist of a continuously variable transmission 6 and an electric motor 5, which are arranged on one above the bearing block 17
  • Frame housing 9 are attached.
  • the frame housing 9 can accommodate an illuminant.
  • the frame housing 9 and the bearing block 17 are fixedly mounted on a platform 10, which can be constructed like a lattice.
  • the platform 10 rests on floating bodies 12 connected to it.
  • the floating bodies 12 are enclosed at the bottom by frame parts 11, which extend from the platform 10, which is not shown in more detail here.
  • the tube 2 is held in the vertical position by a tubular tube holder 13.
  • the tube holder 13 is firmly screwed to the platform 10.
  • the pipe 2 is firmly connected to the pipe holder 13 by pipe clamps 14. Only one pipe holder 13 is shown here, but in practice at least two such holders are used to give the device the necessary stability.
  • two blade stirrers 15 are arranged in a rotationally fixed manner within the tube 2 at a distance from one another.
  • Paddle stirrers 15 each have four inclined blades 16 that rise clockwise when the shaft 3 rotates.
  • a balanced stabilizing stirrer 4 is arranged at the lower end of the shaft 3.
  • the shaft 3 is shown shortened here, but in practice it has a length of 2 m with a diameter of 5 cm.
  • the device 1 is brought into place with the floating platform 10, 11, 12 on a standing body of water, the tube 2 and the shaft 3 being in a horizontal position during transport.
  • pipe 2 and shaft 3 are brought into the vertical position, whereby the pipe extends about 20 m into the water.
  • the platform is anchored in a suitable manner. Partial flooding of the float and adjustment of the tube 2 ensures that the upper edge of the tube 2 is about 10 cm above the water level.
  • the motor 5 is switched on and the transmission 6 is regulated so that the shaft 3 rotates clockwise at a speed of between 56 and 98 revolutions per minute. With the shaft 3, the paddle stirrer 15 rotates with its blades 16 and requests water upwards over the edge of the tube 2, where it breaks and next to the tube 2 into the
  • the agitator can circulate around 180,000 liters of water in 24 hours.
  • the device can also be arranged on a boat or a type of solid structure.
  • the number of paddle stirrers need not be limited to 2 and the length ratios of the tube and shaft can vary.
