As preferably, a bowl-type depression is equipped with at the centre bit of described centrifugal drain pan upper surface, the water sprayed from suction pump can be diverted in each water draining pass by this depression uniformly, effective minimizing current are the kinetic energy of loss because of vertical impact centrifugal drain pan upper surface, thus increase the flow velocity of the water of discharging from each water draining pass.

As preferably, fix a magnet ring at the center that described bowl-type caves in, a magnet that magnetic is attracting with it bound by fishing line, this structure can dismounting sonar fish deteclor fast.

As preferably, in the bottom of described sonar sensor, one buoyancy switch is housed; This buoyancy switch controls the break-make of way circuit and stretches out base bottom; After sonar fish deteclor is put into water, buoyancy switch moves by buoyancy of water, is communicated with 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, and automatically disconnected by circuit, this structure can realize the auto switching of sonar fish deteclor.

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