Description

Prefilter immersible pump Technical Field The utility model belongs to the technical field of water pumps, relates to a submersible pump, and in particular relates to a prefilter submersible pump. Background The submersible pump is drainage equipment with an integrated motor and a water pump, is completely immersed in liquid during operation, and drives an impeller to rotate through the motor to generate centrifugal force, so that water is pressurized and conveyed to a designated position. The self-priming water pump has the advantages of compact structure and good sealing performance, can self-priming without diversion, and is suitable for various scenes such as deep well water taking, farmland irrigation, building drainage, sewage treatment, pond circulation and the like. The immersible pump can set up the filter screen generally, needs the filter screen mainly to prevent impurity (like silt, pasture and water, piece etc.) get into inside the pump body in the water, avoids blockking up impeller, wearing and tearing mechanical seal or damage motor to influence the work efficiency and the life of water pump, but fixed filter screen can lead to too much foreign matter to adsorb and lead to blockking up because of the continuous work of water pump, thereby lead to the water pump idle running to lead to the water pump to burn the machine. Disclosure of Invention The utility model aims to solve the problems in the prior art and provides a submersible pump with an automatic rolling filter screen for preventing blockage. The pre-filtering submersible pump is characterized by comprising a water pump main body, wherein a motor and an impeller are arranged in the water pump main body, a filtering base is arranged at the bottom of the water pump main body, a plurality of overflow holes are formed in the filtering base, a driving disc is arranged in the filtering base, a driving wheel and a driven wheel are arranged in the driving disc, a driving lug is arranged on the driving wheel, a plurality of jogged grooves for jogging the driving lug are formed in the driven wheel, a driving rod is arranged on the driving wheel, guide lugs are arranged between the overflow holes, driving wheel rods are arranged on the driven wheel, guide rods are arranged on two sides of the driving rod, a filtering ring net is arranged on the outer wall of the filtering base, the inner wall of the filtering ring net is in contact with the guide lugs and the driving wheel rods, and the outer wall of the filtering ring net is in contact with the guide rods. In the prefilter submersible pump, the top of the driving rod is provided with the connecting screw thread, the top of the driving rod is connected with the impeller, the filtering base is provided with the locking cover, the locking cover is provided with the connecting bearing, and the driving rod is fixed on the connecting bearing. In the prefilter submersible pump, one side of the driving wheel rod is provided with the extrusion wheel. Compared with the prior art, the prefilter submersible pump enables the filter screen out of the overflow hole to be kept clean continuously by arranging the filter ring net which moves continuously and indirectly, the overflow hole is blocked completely when the overflow hole is in value, the filter ring net can be cleaned in an auxiliary mode by extrusion of the extrusion wheel and the driving wheel rod, blocking of the filter screen is reduced, and a maintenance gap is prolonged.
