As preferably, the centre bit in described centrifugal drain pan upper surface is equipped with a bowl-type depression, The water sprayed from suction pump can be diverted in each water draining pass by this depression uniformly, effectively subtracts The kinetic energy that few current are lost because vertical impact is centrifuged drain pan upper surface, thus increase from each row The flow velocity of the water that road, water hole is discharged.

As preferably, fix a magnet ring at the center that described bowl-type caves in, fishing line is bound One magnet that magnetic is attracting therewith, this structure can quickly dismount sonar fish deteclor.

As preferably, in the bottom of described sonar sensor equipped with a buoyancy switch；This buoyancy is opened Close and control the break-make of way circuit and stretch out base bottom；After sonar fish deteclor is put in water, floating Power switch is moved by buoyancy of water, connects way circuit, thus starts sonar sensor and suction pump； When sonar fish deteclor is taken out from water, buoyancy switch moves down with self gravitation, automatically by circuit Disconnecting, this structure can realize the auto switching of sonar fish deteclor.

As preferably, described pedestal and the described centrifugal drain pan annular groove by one another edge It is rotatably connected.
