DETAILED DESCRIPTION

[0021] To make the purpose, technical scheme and advantages of the embodiments of the utility model more clear, the technical scheme in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all.

[0022] The utility model will be further described below with reference to the drawings and specific embodiments EMBODIMENT

[0024] In summary: fixed glue 16 can play the role of positioning to soundproof cotton 15, so that soundproof cotton 15 is well connected with motor shell 1, soundproof cotton 15 can reduce noise, submersible pump can produce certain noise when working, especially when high load or long time running, noise will be more obvious, using soundproof cotton 15 can effectively absorb and insulate noise, reduce the influence on surrounding environment, improve use experience, meanwhile soundproof cotton 15 can absorb part of condensate water through its porous structure, prevent equipment from damp, prolong service life.

[0025] As Figures 1-4As shown, the rear side of the sealing cover 2 is provided with a cable ring 4, and the end of the cable ring 4 is provided with an elastic band 5, the bottom of the adapter shell 7 is provided with an opening 6, and the inside of the adapter shell 7 is provided with a cutting blade 12, the outer wall of the adapter shell 7 is provided with a conveying pipe 8, and the end of the conveying pipe 8 is provided with an outlet flange 9, the periphery of the adapter shell 7 is provided with a support frame 10, and the bottom of the support frame 10 is provided with a fixed base ring 11, the upper end of the cutting blade 12 is provided with a rotating rod 13, and the upper end of the rotating rod 13 is provided with a servo motor 14.

[0026] In summary: through the cable ring 4, the cable can be stored and positioned, and the elastic band 5 has good inclusiveness and can bind different numbers of cables. The cutting blade 12 is mainly used for cutting garbage, solid substances and fiber impurities in the submersible pump to ensure normal operation of the submersible pump and prolong its service life.

[0027] Working principle: when the submersible pump with spiral cutting knife and blade is in use, first, according to Figures 1-4 , the submersible pump can form negative pressure in the pump body through its pump body design, so as to suck sewage. The pump body usually has a large suction inlet and strong water suction capacity, and can handle a large amount of sewage. The sewage often contains some solid particles such as fibers, cloth and plastic. These particles can cause blockage of the pump body and pipeline, affecting the normal operation of the pump. At this time, the servo motor 14 can be started to drive the cutting blade 12 to rotate. When the sewage passes through the cutting blade 12, the solid particles will be cut into smaller pieces, so as to smoothly pass through the pump body and the conveying pipe 8. The sewage treated by the cutting blade 12 enters the inside of the pump body, and the liquid is worked by the rotation of the impeller to convert mechanical energy into liquid energy. Under the action of the impeller, the liquid is accelerated and ejected, and then the speed gradually decreases and the pressure gradually increases in the diffusion chamber of the pump shell. Finally, it is discharged from the outlet flange 9 of the pump. Noise will be generated during operation. The fixing glue 16 can position the soundproof cotton 15, so that the soundproof cotton 15 is well connected with the motor shell 1. The soundproof cotton 15 can reduce noise. The submersible pump will produce some noise during operation, especially under high load or long time operation, the noise will be more obvious. The use of soundproof cotton 15 can effectively absorb and isolate noise, reduce the impact on the surrounding environment, improve the use experience, and at the same time, the soundproof cotton 15 can absorb part of the condensed water through its porous structure, prevent the equipment from being damp, and prolong the service life.
