152 of the corresponding link 151, with diaphragm 58 pressed tightly (by seal plate 155) between ends 152 and 156b (to forestall liquid leakage into the control field meeting). With reference once more to FIG. 7, cam tracks 50a have similar shapes, however the 2 cams 50 are assembled basically "back-to-again" (one is rotated by 180 degrees in regards to the vertical axis in FIG. 7 relative to the opposite), which orients the cam observe 50a of one of them as the mirror picture of cam track 50a of the other (in order that the angular orientation of one monitor 50a about shaft fifty two is displaced relative to the orientation of the opposite monitor 50a about shaft 52). Similarly, in the FIG. 10A embodiment, two equivalent cams 50' are assembled basically "back-to-again" on shaft 52, thus orienting cam track 50b of one among them because the mirror picture of cam track 50b of the other. As proven in FIGS. A seal plate 155 (shown in FIGS. 155a (shown in FIG. 7) of control box portion 14a. A shift link 156 fits within an opening by the middle of each seal plate 155. As cam 50 pivots link 151 upward (or downward), link 156 at the alternative finish of the inflexible shift assembly (comprising link 151, tube 154, and link 156) will pivot downward (or upward).
Alternatively, the parts are all related to a single circuit board sixty eight (in which case, board 70 is omitted). In a most popular embodiment, the microprocessor is preprogrammed to assert any of two or more units of management alerts to motor 74. For example, the microprocessor can be programmed to assert a primary set of comparatively low present signals to the motor in the event that the batteries powering the apparatus have a low level (or Tempe if the onboard sensors indicate that the apparatus is caught in opposition to an impediment), and otherwise to assert a second set of comparatively excessive present indicators to the motor. Stepper motor 74 and cam gear cluster fifty five are also mounted inside assembled elements 14a, 14b, and 14c. Two cams 50 and one cam gear 54 are fixedly mounted on cam shaft 52. Shaft fifty two is rotatably mounted to factor 14a by cam bearings 51. Thus, cams 50, gear 54, and shaft fifty two rotate together as a unit. Gear cluster 55, engaged between motor Add Listing 74 and cam gear 54, is driven by motor 74 (which is ideally an electronically controlled electric step motor).
The inventors contemplate that the invention can be helpful for other functions, e.g., to clean other surfaces submerged in water or in liquids apart from water. 4 and 13) and an outlet 10. Outlet 10 is dimensioned for attachment to the decrease finish of a flexible hose 8 (proven only in FIG. 13), and so outlet 10 is generally referred to herein as a "hose connection" 10. Typically, the upper finish of hose eight shall be related to one of many Pool cleaning service near me's existing suction ports, which in flip is related to a traditional surface unit 8A (shown in FIG. 13) disposed above the water floor. A first embodiment of the invention will probably be described with reference to FIGS. 1-8 and 11-22. In this embodiment, the invention features a turbine assembly 12 having an inlet 9 (proven in FIGS. The term "water" will probably be used in a broad sense all through the specification, including within the claims, to denote fresh water, salt water, and every other liquid in which a floor (to be cleaned by the inventive apparatus) is immersed.
In any embodiment of the invention, the programming card could be coded with a pattern of notches at along its edges. Use of such a battery pack permits safer and extra convenient operation than could be achieved with Miami Pool Installation cleaners which have employed a energy cable extending to the submerged apparatus from a power provide disposed above the water floor. Selection of a bigger inlet dimension ends in slower, extra thorough, cleansing than is normally achievable with a smaller turbine inlet. When the notched card is positioned into position adjoining the magnetic (or optical or mechanical) switches, the card will (or is not going to) actuate mechanical means for controlling the scale of a turbine assembly fluid inlet nozzle depending on the absence (or presence) of a notch at the situation of the mechanical means. The larger inlet will even permit for passage of bigger debris. In most well-liked embodiments, the inventive apparatus is powered by an onboard battery pack sealed in a water-tight enclosure. The smaller inlet will give higher turbine velocity resulting in larger unit velocity and in addition increase torque for higher wall climbing.
The currents of the "comparatively low" current alerts might be selected to maximise the torque exerted by the motor while minimizing battery consumption, and the currents of the "comparatively excessive" current alerts could be selected to maximize the torque exerted by the motor (with no battery consumption minimization constraint). Each of cams 50 defines a cam monitor 50a (greatest proven in FIG. 5) having a non-uniform radius relative to shaft 52. In variations on this embodiment, cams 50 are replaced by cams 50' shown in FIG. 10A or cams such as the cam having camtrack 50A' proven in FIGS. Thus, the motor could be controlled to consume much less power in response to the "relatively low" current alerts than in response to the "comparatively high" current alerts. 9 and 10. Each of cams 50' defines at the very least one cam track 50b having a non-uniform radius relative to central portion 52a of cam 50' (cams 50' are mounted to shaft fifty two by inserting shaft fifty two through portion 52a of every cam 50'). A pair of cam follower links 151 (one of which is proven in FIG. 7A and in FIG. 7B) are provided, each having a cam follower shaft one hundred fifty which rides in one of the cam tracks 50a or 50b. Or, a pair of cam follower hyperlinks 151' (one shown in every of FIGS.
