- Figure 2 is a perspective exploded view of the geared, water flow driven mechanism of Fig. 1,
- Figure 3 is a perspective view of an angled connector between an end of the hose and the outlet of the scavenging head of Fig. 1.
- Figure 4 is a perspective view of the head of a suction cleaner device provided with a rotation apparatus.
- Figure 5 is an perspective exploded view of a further embodiment of a geared water flow driven mechanism
- Figure 6 is a perspective view of the geared water driven mechanism of Figure 5 when assembled.
- a swimming pool 10 is provided with a suction pump 12, drawing water from a suction cleaner device 14 via hose 16.
- Hose 16 is normally directly connected to a pump inlet pipe 18 at a side wall 20 of swimming pool 10, but in this first preferred embodiment of the invention, hose 16 is connected to an inlet pipe 22 of a geared, water flow driven mechanism 24, Mechanism 24 is in turn, connected by its outlet pipe 26 to inlet pipe 18 of pump 12.
- the inlet end 15 of suction hose 16 is connected, for example as a press fit, to an angled connector 17, which in turn is attached, again for example as a press fit, to the swivelling outlet port 19 of suction cleaner device 14.
- Mechanism 24 provides for rotation of inlet pipe 22 together with hose 16, relative to outlet pipe 26 and outlet port 19 so as to induce axial rotation of hose 16 and of angled connector 17.
- rotation is at a rate of between one and six revolutions per hour.
- outlet pipe 26 is rigidly connected to a first chamber 28 housing a turbine in the form of a paddle wheel 30.
- Paddle wheel 30 is forced to rotate by flow of water (as indicated by dashed line A-
- a first worm gear 34 is mounted to the rotation shaft of paddle wheel 30, and drives first pinion 36 mounted on shaft 38.
- Shaft 38 also carries a second worm gear 40, which in its turn drives second pinion 42.
- Shaft 46 passes through the end 48 of chamber 28 and through cover plate 50 (when cover plate 50 is assembled to chamber 28) to mesh with a ring gear 52 provided at the periphery of output disc 54.
- Inlet pipe 32 is rigidly mounted to output disc 54, so that when paddle wheel 30 rotates and drives the gear train, made up of the worm gears, pinions, spur and ring gear, inlet pipe 32 rotates relative to outlet pipe 26.
- output disc 54 is enclosed by outer cover 55, provided with a central aperture 57 through which inlet pipe 32 projects when the components are assembled together.

- slip ring 60 may be adjusted to expose none, one or more, or all of apertures 59 to an inflow of water created by suction in outlet pipe 26 by the suction pump 12. This allows an adjustment of the flow of water impacting the paddle wheel 30 and hence the rate of rotation of inlet pipe 32 relative to outlet pipe 26.
- Angled connector 17 is arranged such that the axes of its inlet and outlet ends intersect to form a supplementary angle between them of ⁇ ° .
- the value of ex preferably lies in the range of 15° to 45°.
- inlet pipe 32 and outlet pipe 26 are so formed as to allow a push-fit connection between hose 16 and inlet pipe 32, and between pump inlet 18 and outlet pipe 26, so that the mechanism can be readily retro-fitted to existing pool cleaning equipment .
- the head 100 of a suction cleaner device 110 for the floor 112 of a swimming pool incorporates a rotation mechanism 102 comprising a turbine and reduction gear train substantially as described above for the first preferred embodiment.
- the turbine is activated by flow of water entering the underside 104 of head 100 and passing through hose 116 under the influence of a swimming pool filtration system suction pump (not shown) .
- the output disc driven by the paddle wheel of the turbine via the reducing gear train-, carries the inlet end 118 of an outlet port 120.
- Outlet port 120 is in the form of the angled connector previously described.
- Hose 116 is attached via a swivelling connection to the output end 122 of the port 120, and its output end is affixed as a press fit to the inlet pipe (not shown) at the wall of the swimming pool leading to the suction pump.
- the rotation mechanism is incorporated in the head of a suction cleaner device 110 as described above for the second preferred embodiment.
- hose 116 is affixed to output end 122 of outlet port 120 so that hose 116 is caused to rotate axially as port 120 is rotated by mechanism 102.
