| مستخلص: | A swimming pool bottom hydraulic pushed automatic cleaner includes an underwater cleaner and a control power supply connected by a buoyancy cable. The underwater cleaner includes a housing cover, housing body, filter, double extension shaft motor assembly, hydraulic driven jaw-type clutch impeller combination, water inlet/outlet flow passage, wheel and bracket, an isolated hood and a cable with floaters. Along with the changing of the rotating direction of the motor, the impeller combination is 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 adjust the direction after touching the wall. Furthermore, two or more axial-flow pumps are arranged horizontally and parallelly, so that the cleaner has turning function and orderly complete coverage cleaning is realized. |
