UNDERWATER GENERATOR OF DETERRENT SOUNDS Russian patent published in 2013 - IPC A01M29/16 

FIELD: agriculture.

SUBSTANCE: invention relates to devices for non-traumatic deterrence of aquatic dwellers. The underwater generator deterrent sounds comprises a source of compressed air, an air duct, a throttle valve, a storage chamber, an air stream modulator and a valve of branching fault of air pressure. The valve of branching fault of air pressure is made in the form of a cylinder with a solid partition. The partition forms two differently directed cups. The ends of the housing of the valve of branching fault of air pressure are provided with a thread. The thread is connected to the storage chamber and the modulator housing of the air flow. In the cavity of the first cup there is a piston. The piston by compression spring is spring-loaded relative to the solid partition of the cup and is equipped with an end sealing element. In the wall of the housing of the valve of branching fault of air pressure, three groups of radial holes are made. The first group is located on the lower part and the second on the upper part of the walls of the first cup. The third group of radial holes is made in the wall of the second cup lower the end of the housing of the modulator of air flow. The housing of the valve of branching fault of air pressure is tightly crimped with an elastic seal. The part of the housing of the valve of branching fault of air pressure, equipped with the elastic seal is closed by water-permeable cover.

EFFECT: increased efficiency of non-traumatic deterrence, power and reliability in continuous operation in automatic mode, as well as mobility of the complex.
