Hit or when the impact of current or the extruding of the weight of protecting box 7 etc. cause the pressure in inner chamber 66 to rise, now A-B ＞ 0, control
Unit makes the sounding of sound generating mechanism 61 and expels fish.If A-B is more than 0 for continuous more than one minute, expression causes chamber pressure
Increased power source is that the also as non-animal such as fish that can not be driven away by sound is signified, then carries out sounding and drive, and is not imitated
Fruit, now control unit 62 sound generating mechanism 61 is stopped sounding and is revised as preset value B to stop the sound generating mechanism sounding moment the
The pressure that one pressure sensor detects subtracts the difference A obtained by the pressure that second sensor detects.Modification can produce above
If caused by the pressure of interior intracavitary rises to the impact of burst, if after the external force disappearance preset value B can more than difference A i.e.
The phenomenon of duration, the phenomenon that the presence of the phenomenon is unable to be found when can cause to have fish to damage protecting box 7 produce, therefore this
Control unit further has following functional module, i.e., if it find that the pressure that first pressure sensor detects subtracts the second biography
When difference A obtained by the pressure that sensor detects is less than preset value B, preset value B is adjusted to be equal to the moment by control unit 62
The pressure that first pressure sensor detects subtracts the difference A obtained by the pressure that second sensor detects.
Control unit makes the process of the sounding of sound generating mechanism 61 be：Motor 6113 is made forward and reverse reciprocating motion, drive
The rotating of 6113 drive screw of motor 6112, the driving of screw mandrel 6,112 615 left reciprocating motion of dynamic stripper plate, dynamic stripper plate 615 extrude
First air bag 614 and the second air bag 616 so that air-flow flows by whistle 612 between the first air bag and the second air bag, air-flow
By causing whistle sounding to produce sound during whistle 612.
