Hydraulic driven jaw-type clutch impeller combination and swimming pool bottom hydraulic pushed automatic cleaner comprising same

A swimming pool bottom hydraulic pushed automatic cleaner, comprising:

• an underwater cleaner and a control power supply, which are connected together by a 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, wherein the hydraulic driven jaw-type clutch impeller combination includes:
• an impeller with sharp teeth on an end surface of a hub and a shaft sleeve with sharp teeth on an end surface, the two end surfaces with sharp teeth being a pair of meshing surfaces, wherein:
• the shaft sleeve is fixed in the root of an outrigger shaft of a double extension shaft motor assembly;
• the impeller is sleeved on the end portion of the outrigger shaft;
• the impeller is axially slidable and rotatable;
• the impeller and the shaft sleeve constitute a pair of jaw-type clutches;
• and
• along with the changing of the rotating direction of a motor, the impeller and the shaft sleeve are reliably engaged and disengaged under the action of hydraulic power to change the working state of the impeller;
• the housing cover part, the housing body part, the double extension shaft motor assembly, the hydraulic driven jaw-type clutch impeller combination, the water inlet/outlet flow passage and the cable constitute an axial-flow pump with double water injection nozzle;
• both ends of the motor of the double extension shaft motor assembly are provided with outrigger shafts;
• the motor is watertight;
• the hydraulic driven jaw-type clutch impeller combination is installed on the outrigger shaft of the double extension shaft motor assembly;
• the water inlet/outlet flow passage comprises a flow passage, a flow guide cover and a swinging cap;
• the water inlet/outlet flow passage is a water inlet/outlet channel, with a water inlet in the front end and a water outlet in the tail end;
• the housing cover part comprises a housing cover and a lock catch;
• the housing body part comprises a housing body, a one-way water inlet valve, a suction pipe, a one-way drain valve and a deflection member;
• the housing cover and the housing body are hermetically connected with each other through the lock catch;
• the one-way water inlet valve is arranged at the bottom of the housing body;
• the suction pipe is extracted from the front and rear ends at the bottom of the housing body, and extended under the leading and trailing edges of the underwater cleaner;
• the deflection member is an adjustment feeler lever arranged in the leading edge of the housing cover;
• the filter comprises a filter bracket and a filter bag;
• the filter is installed at the bottom of the housing body;
• the one-way water inlet valve and the upper end of the suction pipe are arranged within the filter;
• the wheel and the bracket is fixedly installed on the side of the housing body;
• the isolated hood is placed between the filter and the double extension shaft motor assembly and installed on the housing cover;
• and
• the control power supply comprises a power supply, a control circuit and a chassis.
