Detailed description of the invention
Develop simultaneously embodiment below in conjunction with accompanying drawing, describe the present invention.
The invention provides the self power generation underwater sound source sound-producing device of a kind of pull-type;
Principle idea is that of this device design requires both to contain low-frequency acoustic signal and intermediate-freuqncy signal due in the sound field that sound source produces, therefore the present invention accounts for from following two aspects:
On the one hand, pull-type sound source towed body is installed propeller impeller under water, when the towed motion of underwater towed-body, aqueous medium flows through the blade of propeller impeller, drive propeller wheel rotation, the rotation of propeller impeller drives the alternator operation within underwater towed-body, the alternating current that alternating current generator produces is through commutator and manostat, it is changed into unidirectional current, thering is provided electric energy for the signal generator in underwater towed-body and power amplifier, signal generator and power amplifier drive low frequencies transducer to launch low-frequency acoustic signal;
On the other hand, aqueous medium flows through the blade of propeller impeller, rubs with blade, and causes the vibration of blade to produce propeller noise. The power spectrum characteristic of this propeller noise and self rotating speed of its rotating shaft have very strong contacting, and its signal main energetic concentrates on medium and low frequency section.
