A passive sonobuoy with its own power generation device

Abstract

The invention discloses a passive sonobuoy with its own power generation device, which includes a casing, a buoyancy bag, a watertight electronic cabin, and a transducer. The watertight electronic cabin is sealed with a main control circuit board, and also includes a power generation device and a damping disc, the buoyant bag, the generating device, the watertight electronic cabin, the damping disc, and the transducer are connected by a flexible cable, and a Beidou antenna is connected on the inner wall of the buoyant bag, and the described generating device uses To supply power to the Beidou antenna, the main control circuit board and the transducer, the Beidou antenna is connected to the main control circuit board. The passive sonobuoy with its own power generation device of the present invention can provide continuous electric energy for the electronic devices in the buoy, which solves the problem that the current buoy cannot supply power for a long time.

Description

technical field [0001] The invention relates to a buoy, in particular to a passive sonar buoy with its own power generation device. Background technique [0002] Passive sonobuoys are usually launched by aircraft, and start working immediately after the buoy enters the water. The block diagram of the passive sonobuoy system is shown in figure 1 shown. The transducer completes the conversion of the acoustic signal to the electrical signal, that is, the acoustic signal in the underwater acoustic field where the transducer is located is converted into a corresponding electrical signal. Since the buoy is to transmit useful information representing the characteristics of the underwater target, including the propeller in the target radiation noise Shaft frequency and blade frequency, etc. Therefore, the appropriate working frequency band is selected by setting the low-frequency amplifier circuit accordingly, and the useful information contained in the frequency band is amplified,...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problem that the existing buoys have a short working time and are limited by the power supply and the flight time of the aircraft, the present invention provides a passive sonar buoy with its own power generation device, which can use seawater waves to generate electricity by itself. The electronic device provides continuous power and has the function of Beidou satellite communication, which is not limited to only communicate with the airborne equipment at a specific location
