AUTOMATIC CLEANING MACHINE WITH A HYDRAULIC DRIVE JAW TYPE CLUTCH IMPELLER COMBINATION

The present invention relates to a swimming pool bottom hydraulic pushed automatic cleaner, comprising an underwater cleaner and a control power supply, which are connected by a buoyancy cable, wherein the underwater cleaner comprises a housing cover part, a housing body part, a filter, a double extension shaft motor assembly, a hydraulic driven jaw-type clutch impeller combination, a water inlet/outlet flow passage, a wheel and bracket, an isolated hood and a cable with floaters. Along with the changing of the rotating direction of the motor, the hydraulic driven jaw-type clutch impeller combination is reliably engaged and disengaged under the action of hydraulic power to change the working state of the impeller, thereby changing water outlet of injection water flow and further changing the travel direction of the cleaner. The housing touches a wall to cause the cleaner to automatically adjust the direction after touching the wall, so as to change the travel route after touching the wall. A suction pipe and a one-way drain valve are arranged to prevent the cleaner from disturbing and diffusing the sewage at the pool bottom during traveling and reduce the weight of the cleaner when taken out from water. Furthermore, two or more axial-flow pumps are arranged horizontally and in parallel, so that the cleaner has turning function and orderly complete coverage cleaning is realized.
