piece

2 and 3 fixed connection of intake end, floating part 4 and 3 fixed connection of intake end,

filter mantle

5 and 2 fixed connection of connecting piece, and filter mantle 5 covers

intake end

3, 3 water inlets of intake end are located and are equipped with the filter screen, wherein intake hose 1 is flexible hose, floating part includes the floater, the floater passes through connecting piece and intake end fixed connection, the floater reciprocates along with the water level change. In the suction pump working process, the pump body passes through flange joint with the hose of intaking, the hose of intaking also passes through flange joint with the end of intaking, along with the sewage in the suction pump extraction effluent water sump, the end of intaking is through the floating piece rather than fixed, the floater promptly, can float from top to bottom along with the water level change, the buoyancy that this floater provided guarantees that the end of intaking floats on the effluent water sump surface all the time, the suspension coal grain in the effluent water sump carries out prefiltering through the outer filter mantle of the end of intaking earlier, the rethread end of intaking filters once more, sewage after the filtration can be more convenient does further processing, the end of intaking keeps on the effluent water sump surface all the time simultaneously, avoided stopping up the port of intaking more and more because of the coal deposit at the bottom of the effluent water sump, and then lead to the problem of entire system trouble. Meanwhile, no matter how the water level changes, the water inlet hose is kept above the water level all the time due to the fact that the water inlet hose is telescopic, and therefore corrosion of sewage is avoided.

Example 2:

the utility model provides a floating water pump water installations, wherein floating part includes the kickboard, and the connecting piece passes the kickboard, and end and connecting piece fixed connection intake, suction pump during operation, the kickboard reciprocates along with the water level change, also floats on the effluent water sump surface all the time simultaneously rather than fixed end of intaking, has avoided more and more blockking up the port of intaking because of the coal deposit at the bottom of the effluent water sump, and then leads to the problem of entire system trouble. The rest of the structure is the same as that of example 1.

Example 3:

the utility model provides a floating water pump water installations, still includes the automatic switch subassembly, and the automatic switch subassembly includes controller and level sensor, and controller and suction pump pass through the relay and connect, and controller and level sensor are connected, and level sensor locates the pond bottom, and the controller includes the PCB board, is equipped with control circuit on the PCB board, and control circuit receives the water level information of level sensor input, and rethread relay electrical apparatus control suction pump starts and closes. In the working process, select to set for the water level according to long-pending coal measure in whole effluent water sump, before not reaching to set for the water level, the suction pump operation constantly takes out sewage, when reaching to set for the water level, the controller passes through the relay and closes the suction pump, and the suction pump stops drawing water. The problem that the water inlet end is too close to the bottom of the sewage pool after the water level of the sewage pool is reduced, and the accumulated coal at the bottom of the sewage pool blocks the water inlet port to cause equipment failure is avoided. Therefore, after the set water level is selected, the whole sewage pump can realize autonomous operation and automatic water inlet. The rest of the structure is the same as that of embodiment 1 or embodiment 2.
