152 of the corresponding link 151, with diaphragm 58 pressed tightly (by seal plate 155) between ends 152 and 156b (to stop liquid leakage into the management box meeting). With reference again to FIG. 7, Vineyard Pools cam tracks 50a have similar shapes, but the 2 cams 50 are assembled primarily “back-to-back” (one is rotated by 180 levels about the vertical axis in FIG. 7 relative to the other), which orients the cam monitor 50a of one in all them as the mirror picture of cam monitor 50a of the other (so that the angular orientation of 1 track 50a about shaft fifty two is displaced relative to the orientation of the other track 50a about shaft 52). Similarly, in the FIG. 10A embodiment, two identical cams 50′ are assembled primarily “back-to-back” on shaft 52, thus orienting cam observe 50b of certainly one of them as the mirror image of cam monitor 50b of the opposite. As proven in FIGS. A seal plate 155 (proven in FIGS. 155a (shown in FIG. 7) of management field portion 14a. A shift link 156 fits within an opening through the middle of each seal plate 155. As cam 50 pivots link 151 upward (or downward), hyperlink 156 at the alternative end of the inflexible shift meeting (comprising hyperlink 151, tube 154, and link 156) will pivot downward (or upward).
Alternatively, the components are all connected to a single circuit board 68 (through which case, board 70 is omitted). In a preferred embodiment, the microprocessor is preprogrammed to assert any of two or extra units of management signals to motor 74. For instance, the microprocessor could be programmed to assert a first set of relatively low present indicators to the motor in the occasion that the batteries powering the apparatus have a low stage (or if the onboard sensors indicate that the apparatus is stuck towards an obstacle), and otherwise to assert a second set of comparatively excessive present alerts to the motor. Stepper motor seventy four and cam gear cluster fifty five are also mounted within assembled parts 14a, 14b, and 14c. Two cams 50 Yaku Pools and Construction – San Fernando Valley one cam gear 54 are fixedly mounted on cam shaft 52. Shaft fifty two is rotatably mounted to element 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 74 and cam gear 54, is pushed by motor 74 (which is preferably an electronically managed electric step motor).
The inventors contemplate that the invention can be helpful for different applications, e.g., to wash different surfaces submerged in water or in liquids aside from water. Four and 13) and an outlet 10. Outlet 10 is dimensioned for attachment to the lower end of a flexible hose 8 (proven solely in FIG. 13), and so outlet 10 is typically referred to herein as a “hose connection” 10. Typically, the higher finish of hose 8 will probably be linked to one of the Texas Teal Pool Services‘s current suction ports, which in flip is related to a standard floor unit 8A (proven in FIG. 13) disposed above the water surface. A primary embodiment of the invention will be described with reference to FIGS. 1-8 and 11-22. In this embodiment, the invention features a turbine meeting 12 having an inlet 9 (proven in FIGS. The time period “water” can be used in a broad sense all through the specification, including in the claims, to indicate fresh water, salt water, and another liquid by which a surface (to be cleaned by the inventive apparatus) is immersed.
In any embodiment of the invention, the programming card will be coded with a pattern of notches at alongside its edges. Use of such a battery pack permits safer and extra handy operation than can be achieved with Inground Pool Prices California cleaners which have employed a power cable extending to the submerged apparatus from a energy supply disposed above the water floor. Selection of a larger inlet size leads to slower, extra thorough, cleaning than is generally achievable with a smaller turbine inlet. When the notched card is placed into place adjacent the magnetic (or optical or mechanical) switches, the card will (or is not going to) actuate mechanical means for controlling the size of a turbine assembly fluid inlet nozzle depending on the absence (or presence) of a notch at the location of the mechanical means. The larger inlet will also permit for passage of larger 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 greater turbine pace leading to greater unit velocity and likewise improve torque for better wall climbing.
The currents of the “comparatively low” present signals may be chosen to maximize the torque exerted by the motor whereas minimizing battery consumption, and the currents of the “relatively high” present 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 observe 50a (best shown in FIG. 5) having a non-uniform radius relative to shaft 52. In variations on this embodiment, cams 50 are changed by cams 50′ proven in FIG. 10A or cams such because the cam having camtrack 50A’ shown in FIGS. Thus, the motor can be controlled to devour less power in response to the “comparatively low” current signals than in response to the “relatively excessive” present signals. 9 and 10. Each of cams 50′ defines at the least one cam monitor 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 each cam 50′). A pair of cam follower hyperlinks 151 (one among which is shown in FIG. 7A and in FIG. 7B) are offered, each having a cam follower shaft one hundred fifty which rides in one of many cam tracks 50a or 50b. Or, a pair of cam follower links 151′ (one proven in every of FIGS.
