Definitions

  • the invention relates to an independently moving machine according to the preamble of claim 1.
  • FIG. 1 A water turbine, not shown, drives via its shaft-mounted turbine gear 11 and a shift gear 4 an intermediate gear and reduction gear 6, which is in engagement with a plate drive gear 8 and sets a suction plate 2 in slow continuous rotary motion with the axis of rotation B via a centrally located suction nozzle 10.
  • a suction plate 1 is rotated via gears 3, 5, 7 and suction nozzle 9.
  • the directions of rotation are indicated by arrows.
  • Both suction plates 1 and 2 made of elastic material, such as silicone rubber, rotate in the opposite direction of rotation and slide over the pool floor.
  • the existing swimming pool filtration systems work with different amounts of water and suction power, which are reduced in the machine by valve control to acceptable, uniform operating values.
  • a suction pressure of 2o mbar is sufficient to achieve a suction plate contact pressure of approx. 2oo N.
  • the machine can thus safely move up to the water surface of a swimming pool lined with plastic sheeting without removing the sheeting from the outer wall by suction.
  • FIG. 2 A possible suction plate control is explained using a sectional drawing according to FIG. 2.
  • An elongated housing 53 has two filter chambers 14 and 15 and a turbine chamber 24 arranged between them.
  • the suction plates 1 and 2 are rotatably mounted in the bottom of the housing 53.
  • the suction line of the filter system is attached to a rising pipe 13 of the machine, which can be rotated axially relative to the housing 53, via a flexible suction hose (not shown).
  • the entire water flow now flows through the inner tube of the suction nozzle 10 provided with a non-return flap 16 into the filter chamber 14, then through a filter screen 18 and an open valve flap 20 into the turbine chamber 24 and through a water turbine 25 to the riser tube 13.
  • the water turbine 25 runs and drives via a drive shaft 26 and the turbine gear 11, the reduction gear 5 and 6 and the suction plates 1 and 2, as described above.
  • the plate drive gear 7 rigidly connected to the suction nozzle 9 additionally controls a driver via an eccentric disk, not shown lever 23, which brings the two valve flaps 20 and 21 into their opposite switching positions via a switching rod 22.
  • the water flow will proceed analogously through the suction port 9 released by a non-return flap 17 and a filter screen 19, the open valve flap 21, the turbine chamber 24 and the water turbine 25 to the riser pipe 13.
  • the suction plate 2 will, for example, suck onto the floor and interrupt the water supply; the suction force increases to approx. 5ooo N.
  • the installation of a compensating valve arrangement helps to remedy the situation, whereby the open valve passage should be larger than double the inner suction port.
  • the water coming from outside flows in the direction of the arrow (FIG. 2) through a compensating valve 27 into a valve chamber 32 within a valve box 52, then through a compensating valve 28 into a valve channel 33 and an opening 54 in the outer tube 73 of the suction nozzle 10 under the suction plate 2.
  • the water is diverted through the basin floor at a high flow rate under the suction port 10, whereby a great cleaning effect is achieved.
  • a spring 35 of the compensating valve 29 is responsible for the forces under the suction plate 1.
  • the suction plate 1 will rotate freely around the suction plate 2 sucked in in the manner described.
  • a vacuum is also built up under it, which, however, has to be much weaker than that under the suction plate 2.
  • the adjustment is made with the spring 36 of the compensating valve 27.
  • the water flowing freely from the outside becomes during amplification the Spring 36 opposes an increased entry resistance, whereby a negative pressure is built up in the valve chamber 32, which continues with an open check valve 31 through a valve channel 43 to under the suction plate l. If the suction plate 1 does not lie flush on the pool floor, no negative pressure can build up, which causes the compensating valve 27 to close and the entire suction flow under the suction plate 1 to pull the water away, which immediately results in a ground closure.
  • a roller chain 39 (FIG. 2), which is anchored rotatably on the two suction ports 9 and 10, interrupts the bottom closure of the two suction plates 1 and 2 at one point.
  • a local water flow is created, through which larger sediments, e.g. Sheets under which suction plates are conveyed.
  • the suction plates 1 and 2 are identical and have radial water passage channels 40 (FIGS. 2 and 5) from the center, which open into a concentric compensating bead 38. Further out there is a sealing flange 37 with an edge 42 bent upwards. If the machine moves over the basin floor and reaches an upright wall at an angle of, for example, 45 ° (FIG. 3), the edge 42 ( Fig. 2) bent over with the sealing flange 37 over the compensating bead 38, whereby water can flow in. The fixed suction pressure under the suction plate 2 coincides and the suction plate 1 is no longer moved forward.
  • the suction plate 1 sucks and presses the suction plate 2 even more firmly against the wall.
  • These processes are repeated alternately until the suction plate 2 has pushed through the wall and the machine is again moved in direction D (Fig. 3).
  • the machine moves vertically in the direction of arrow E towards a wall, the edges 42 on both suction plates 1 and 2 are pushed up and the suction plates lose great grip, which has a gentle effect on the mechanics. Relief from this operating situation is achieved via a programmed forced release, which is designed in such a way that a changeover gear, which is explained later and which is connected downstream of the turbine, reverses the directions of rotation of all gearwheels. The machine therefore moves backwards.
  • valve flap 20 and 21 (FIG. 2) is open for the suction plate 2.
  • the suction plate 1 rotates in the direction of the arrow around the suction plate 2.
  • the return time respectively. the angle of rotation swept during this time is decisive for the direction that the machine takes when switching back to forward running.
  • the preprogrammed return times alternately result in different directions of departure (F i , F 2 , F 3 ) from the wall (FIG. 4).
  • the return angle between 0 and 200 °
  • the machine will return to the wall with a return angle between 0 to 45 °, with a return angle between 45 and 90 ° deflect in direction D (Fig. 3) and with a return angle between Move 90 and 180 ° in the directions F 1 to F 3 , with a return angle of more than 180 ° always moving away from the wall at right angles in the direction F 2 .
  • the bottom of the suction plate, supported by the compensating bead 38 (FIGS. 2 and 5) and prestressing springs 41, is maintained, which means that the machine over the radius on a side wall of the swimming pool and climbs on it.
  • the reversal is initiated via a buoyancy body 44 or 45 (FIG. 5), as a result of which the machine changes the direction of travel in the manner described above.
  • the return angle is limited to a maximum of 100 ° so that the freely rotating suction plate does not move beyond the water surface, which would suck in air.
  • a slide 46 is pressed to the right by an expansion spring 47 and presses a rocker switch 60 to the left, so that the switching gear 3 is in engagement with the reduction gear 5.
  • the corresponding directions of rotation are indicated by arrows.
  • a release pawl 58 is ge by one of the buoyancy bodies 44 and 45 upwards pulled and tensioned a spring 61.
  • the switching gear 3 Due to the large power transmission from the water turbine to the suction plate, the switching gear 3 has the tendency to remain in engagement between the turbine gear 11 and reduction gear 5.
  • the flipped slider 46 abuts with a cam 49 on a pawl 50 which, via a pivot point 65, releases a pull lever 63 which hangs on a bolt 66 of the plate drive gear 7 and thus pulls the shift gear 3 out of engagement against its own holding force.
  • the rocker switch 60 can then switch unhindered into the position shown in FIG. 7.
  • the situation is exactly the opposite in the transmission of power, after which the switching gear 4 presses itself out of the tooth engagement. Remedy is created via a pawl 64, which prevents the rocker switch 60 from pivoting out.
  • the bolts 69 and 70 from the program gear 67 are not the same high and the reset lever 68 can be by a gravity rocker 71 in the level shift, which causes in a horizontal operating position only the longer bolt 70 causes the default, whereby the previously described larger return angle of eg 200 is turned on 0th
  • both bolts 69 and 70 can trigger the reset, and the maximum return angle is only half as large, ie 100 °, for example.
  • the turbine chamber 24 can additionally be provided with a window 75 'which can be closed by a flap 75, see FIGS. 5 and 7.
  • a pressure lever 76 Adjacent to the plate drive gear 8 is a pressure lever 76 which is displaceable in its longitudinal direction and can be pivoted to a limited extent.
  • One end of the pressure lever 76 rests on the inside of the flap 75, which is kept closed by a spring 82, as long as the pressure lever 76 does not act on the flap 75.
  • the other end region of the pressure lever 76 is connected to the release pawl 58 via a pulling element 77 and is pivoted clockwise in relation to FIG. 7 by buoyancy, which acts on the buoyancy body 44, so that the upper end of the pressure lever 76 is disengaged from the Driving pin 59 of the plate drive gear 8 is.
  • the pressure lever 76 is pivoted counterclockwise by a tension spring 79 and is in contact with a pin 80. Now the upper end of the pressure lever 76 is in the path of movement of the driving pin 59. When the plate drive gear 8 rotates clockwise, the driving pin 59 will push the pressure lever 76 downward, whereby the flap 75 opens. In the lower position, the pressure lever 76 is held by a cam which engages behind a stop pin 78. As soon as again acted on the buoyancy body 44 acts, the pressure lever 76 is returned to its rest position. This causes the flap 75 to be closed again and the cleaning device to move forward as described above.
