In the working process, when the first conical grinding wheel 12 and the second conical grinding wheel 13 are meshed, connected and rotate, particulate matters in liquid flow to a gear meshing joint to easily cause the first conical grinding wheel 12 and the second conical grinding wheel 13 to be incapable of rotating, the protective cover 18 is arranged outside the working parts of the first conical grinding wheel 12 and the second conical grinding wheel 13 to prevent the particulate matters from entering the gear meshing joint to ensure that the first conical grinding wheel 12 and the second conical grinding wheel 13 can work normally, in addition, the second filter screen 19 is arranged on the protective cover 18, the liquid can enter the protective cover 18 through the second filter screen 19 when the transmission rod 11 moves up and down, so that the internal pressure of the protective cover 18 is kept constant, the transmission rod 11 can normally move up and down, the second filter screen 19 also avoids the problem that the particulate matters enter the protective cover 18, and the fixing rod 17 is used for fixing the protective cover 18, thereby ensuring proper operation of the protective cover 18.
The using method comprises the following steps: the invention drives the components in the water pumping chamber 2 to work through the work of the motor 1, so as to pump the liquid from the water pumping pipe 5 and finally discharge the liquid from the water outlet 3, when the liquid passes through the inside of the treatment chamber 4, larger particles in the liquid can be filtered by the first filter screen 9, so as to prevent the larger particles from entering the water pumping chamber 2, avoid the problem that the larger particles contact and damage the components when moving with the components in the water pumping chamber 2, cause the shortening of the service life of the submerged centrifugal pump, large particles can be left on one side of the first filter screen 9 when being filtered by the first filter screen 9, the first filter screen 9 can be blocked due to long-time accumulation, cause the pressure on one side of the first filter screen 9 with the particles to be larger and the pressure on the other side to be smaller, the first filter screen 9 can move upwards due to the pressure difference, thereby driving the fixing ring 8 to compress the spring 10, the trigger head 14 can push against the elastic membrane 20 in the moving process, then the trigger head 14 drives the elastic membrane 20 to squeeze the elastic electrode sheet 21, so that the elastic electrode sheet 21 is deformed to touch the conductive sheet 22, at this time, the first lead 23 is connected to the second lead 24, because the first lead 23 and the second lead 24 are power lines of the micro motor 6 and the motor 1 share one power source, when the first lead 23 is connected to the second lead 24, the micro motor 6 starts to operate, in addition, the first filter screen 9 drives the transmission rod 11 to move upwards when moving upwards, so as to drive the second tapered grinding wheel 13 on the transmission rod 11 to move, and finally touch the first tapered grinding wheel 12 and contact with the first tapered grinding wheel 12, and the outer surface roughness of the first tapered grinding wheel 12 and the outer surface roughness of the second tapered grinding wheel 13 are used for increasing the friction force of the first tapered grinding wheel 12 connected to the output end when the micro motor 6 operates, because the surface roughness friction force of the contact point of the first tapered grinding wheel 12 and the second tapered grinding wheel 13 is large, the rotation of the first tapered grinding wheel 12 drives the first tapered grinding wheel 12 to rotate The two-cone-shaped grinding wheel 13 rotates to drive the transmission rod 11 and the blade 15 to rotate, the blade 15 rotates to crush larger particles at the first filter screen 9 into micro particles, thereby being capable of passing through the first filter screen 9, avoiding the problem of blockage of the first filter screen 9, and in addition, the impact force of the micro particles which are contacted with the working parts in the pumping chamber 2 is small and is not enough to damage the working parts in the pumping chamber 2, thereby prolonging the service life of the submerged water pump, after the larger particles are crushed, the first filter screen 9 is not blocked, the pressure on the two sides is balanced, the spring 10 can push the fixed ring 8 and drive the first filter screen 9 to move downwards, thereby driving the first lead 23 and the second lead 24 to be disconnected, and realizing that the circuit of the micro motor 6 is switched on and off by blocking and unblocking the first filter screen 9, wherein the movable groove 7 provides a movable space for the movement of the spring 10 and the fixed ring 8.
In addition, the micro motor 6 drives the transmission rod 11 to rotate, and simultaneously drives the brush 16 to rotate, the brush 16 rotates to push out the particles blocked at the filter holes, so that the pushed particles are crushed by the rotating blade 15, the problem that the first filter screen 9 is blocked is avoided, and the crushing effect of the blade 15 is improved.
