Self-cleaning shield pump
By designing a self-cleaning mechanism in the canned motor pump, the impeller rotation drives the cleaning brush and guide block to push the slide bar to extend and retract, thus solving the problem of impurities entering the pump body and achieving the effect of reducing the risk of blockage and maintenance costs.

AI Technical Summary
Technical Problem
If the medium in an existing canned motor pump is not cleaned sufficiently, impurities can easily enter the pump, causing blockages and wear, which affects the operation and lifespan of the equipment.
Method used
A self-cleaning shielded pump was designed, comprising a pump body and a cleaning mechanism. The cleaning mechanism includes a connecting pipe, a bracket, and a cleaning component. The impeller rotation drives the cleaning brush and guide block to push the slide bar to extend and retract, intercepting and removing large impurities in the conveyed medium.
Benefits of technology
It effectively prevents impurities from entering the pump body, reduces the risk of blockage, and minimizes equipment failure and maintenance costs.

Abstract
The self-cleaning shield pump comprises a pump body and a cleaning mechanism, the cleaning mechanism comprises a connecting pipe, a support and a cleaning assembly, the connecting pipe is provided with an opening and an in-pipe space communicated with the opening, the support is fixed in the in-pipe space, and the cleaning assembly is connected with the inner wall of the connecting pipe. The cleaning assembly comprises an outer ring, an impeller and a cleaning brush, the impeller is fixedly connected with the outer ring, the cleaning brush is arranged on the outer ring, the cleaning mechanism further comprises a plurality of sliding rods, a plurality of guide blocks and a plurality of elastic pieces, the sliding rods are slidably connected to the support, the elastic pieces are arranged on the sliding rods in a sleeving mode, the guide blocks abut against the sliding rods, and the guide blocks are fixedly connected with the cleaning assembly. The multiple sliding rods, the multiple guide blocks and the multiple elastic pieces are arranged in a one-to-one correspondence mode, and the cleaning mechanism can effectively intercept large impurities in a conveying medium and prevent the large impurities from entering a pump body of the shield pump, so that the risk that the pump body is blocked is reduced, and equipment faults and maintenance cost caused by impurity blocking are reduced.
