Description of the working principle: when the dry-wet dual-purpose oil-water cooling motor works underwater, water is pumped into the water circulation chamber by the external water pumping mechanism, then the water enters the shell water cooling chamber 2 and the machine-sealed water cooling chamber 5 through the outer side water inlet cooling channel, and then the water flow enters the inner side water outlet cooling channel 22 to spirally advance so as to adsorb heat emitted by the rotor in the rotation process; when the dry-wet dual-purpose oil-water cooling motor works underwater, when an external water pumping mechanism pumps water, water with sludge is often easily pumped into the case water cooling chamber 2 and the mechanical seal water cooling chamber 5, because the external water inlet cooling channel is designed to extend towards the mechanical seal water cooling chamber 5 in a spiral manner, the water flow spirally advances through the external water inlet cooling channel, and because the ratio of the distance of the external spiral radiating fins 21 at the position of the external spiral radiating fins 21 close to the water inlet 1 to the distance of the external spiral radiating fins 21 away from the water inlet 1 is 1:1.5, after the water flow enters the dense external spiral radiating fins 21 from the sparse external spiral radiating fins 21, the water flow spirally accelerates, and after the water flow after the spiral acceleration enters the internal water inlet cooling channel, because the internal water inlet cooling channel is communicated with one end of the external water inlet cooling channel far from the water inlet 1 and extends towards the case water cooling chamber 2 in a spiral manner, and the internal spiral radiating fins 221 extend towards the position of the water outlet 4 The ratio of the distance between the inner spiral radiating fins 221 and the inner spiral radiating fins 221 far away from the water outlet 4 is 1.5:1, after water flow enters the denser outer spiral radiating fins 21 from the more sparse outer spiral radiating fins 21, the water flow is spirally accelerated at the moment, sludge is reduced and is adsorbed on the machine shell water cooling chamber 2 and the machine seal water cooling chamber 5 when the water flow is turbulent, and meanwhile, when the water flow is spirally accelerated, even if part of sludge is adsorbed on the machine shell water cooling chamber 2 and the machine seal water cooling chamber 5, the sludge can be flushed out by the spirally accelerated water flow; the acceleration of the water flow can more quickly bring out the heat emitted by the rotor; part of sludge which is not washed out is adsorbed in the inner side water outlet cooling channel 22, the flow limiting valve is opened at the moment to discharge water flow, the flow limiting handle 9 is rotated at the moment to drive the flow limiting rotating shaft to rotate, and further to drive the flow limiting resistance sheet 11 to rotate, so that the flow limiting resistance sheet 11 is parallel to the flow limiting shell 10, at the moment, the water flow in the inner side water outlet cooling channel 22 flows the distributed part through the flushing pipe and then flows out of the motor shell through the flow limiting valve, and because the flushing pipes with different nodes are designed on the inner side water outlet cooling channel 22 and the directions of the flushing pipes are consistent, at the moment, when the water flow flows out through the flushing pipe, the water flow in the inner side water outlet cooling channel 22 forms stirring, so that the sludge adsorbed in the inner side water outlet cooling channel 22 is flushed and stirred, and then the sludge is carried; the current-limiting rotary channel 12 designed on the current-limiting resistance sheet 11 will accelerate the water flow passing through the current-limiting rotary channel 12, so that the water flow in the inside water outlet cooling channel 22 is stirred more violently, when the water flow enters the flow-limiting valve through the flushing pipe, part of the water flow directly flows out of the motor shell through the flow-limiting valve, while the remaining portion of the water flow will enter the restricted flow vortex 12 through the inlet of the restricted flow vortex 12, then the water is sprayed out through the gradually reduced outlet pipe diameter and then is gathered into the water flow which directly flows out through the flow limiting valve, and thus the flow velocity of the portion of the water flow is increased, and the flow velocity of the flow restriction valve is increased, the stirring of the water flow in the inside outlet cooling channel 22 will be more violent, then stirring the sludge adsorbed on the water outlet cooling channel 22 at the inner side, washing the sludge out by water flow, and flowing out of the motor shell through the washing pipe and the flow limiting valve;
